Introduction: Double-blind placebo-controlled studies investigating the effect of a few-foods diet (FFD) on attention-deficit/hyperactivity disorder (ADHD) have provided consistent evidence that ADHD can be triggered by foods, indicating the existence of a food-induced ADHD subtype. In 2001 the “few-foods” approach was included in an ADHD treatment protocol. This approach consists of (a) determining, by means of an FFD, whether food is a trigger of ADHD; (b) reintroducing, in FFD responders, foods to assess which foods are incriminated; (c) finally composing a personalised diet eliminating the involved foods only. In the Netherlands the few-foods approach is applied in practice. We aimed to retrospectively assess its effectiveness on ADHD and oppositional defiant disorder (ODD) in real life. Methods: Data from all children who started the few-foods approach in three specialised healthcare facilities during three consecutive months were included. Behavior was assessed at start and end of the 5-week FFD, using the ADHD Rating Scale and a structured psychiatric interview. Clinical responders (behavioral improvements ≥40%) proceeded with the reintroduction phase. Results: Data of 57 children, 27 taking medication and 15 following some elimination diet at start, were available. No differences were noted between parental scores of children with and without medication or some elimination diet at start. 21/27 (78%) children stopped taking medication during the FFD. 34/57 (60%) children were ADHD responders, 20/29 (65%) children meeting ODD criteria were ODD responders. 26/34 (76%) ADHD responders started the reintroduction phase; 14/26 (54%) still participated at six months. Teacher data were available of 18/57 (32%) children. 9/18 (50%) children were ADHD responders. Conclusion: The FFD, if applied by trained specialists, may lead to clinically relevant reduction of ADHD and ODD symptoms in general practice, and a concomitant decrease of ADHD medication. These results corroborate the existence of an ADHD subgroup with food-induced ADHD. Defining and eliminating the incriminated foods, i.e. the underlying causal triggers, may result in secondary prevention of food-induced ADHD. Research into underlying mechanism(s) is of vital importance: finding an easier method or biomarkers for diagnosing food-induced ADHD and ascertaining the incriminated foods may lead to redundancy of the few-foods approach.

Alzheimer’s disease - cognition - memory clinic - nutrition - prevention - subjective cognitive decline
As nutrition is one of the modifiable risk factors for cognitive decline, we studied the relationship between dietary quality and clinical characteristics in cognitively normal individuals with subjective cognitive decline (SCD). We included 165 SCD subjects (age: 64 ± 8 years; 45% female) from the SCIENCe project, a prospective memory clinic based cohort study on SCD. The Dutch Healthy Diet Food Frequency Questionnaire (DHD-FFQ) was used to assess adherence to Dutch guidelines on vegetable, fruit, fibers, fish, saturated fat, trans fatty acids, salt and alcohol intake (item score 0-10, higher score indicating better adherence). We measured global cognition (Mini Mental State Examination), cognitive complaints (Cognitive Change Index self-report; CCI) and depressive symptoms (Center for Epidemiologic Studies Depression Scale; CES-D). Using principal component analysis, we identified dietary components and investigated their relation to clinical characteristics using linear regression models adjusted for age, sex and education. We identified three dietary patterns: (i) "low-Fat-low-Salt", (ii) "high-Veggy", and (iii) "low-Alcohol-low-Fish". Individuals with lower adherence on "low-Fat-low-Salt" had more depressive symptoms (β -0.18 (-2.27--0.16)). Higher adherence to "high-Veggy" was associated with higher MMSE scores (β 0.30 (0.21-0.64)). No associations were found with the low-Alcohol-low-Fish component. We showed that in SCD subjects, dietary quality was related to clinically relevant outcomes. These findings could be useful to identify individuals that might benefit most from nutritional prevention strategies to optimize brain health.

Objectives: Tobacco flavours are an important regulatory concept in several jurisdictions, for example in the USA, Canada and Europe. The European Tobacco Products Directive 2014/40/EU prohibits cigarettes and roll-your-own tobacco having a characterising flavour. This directive defines characterising flavour as 'a clearly noticeable smell or taste other than one of tobacco [⋯]'. To distinguish between products with and without a characterising flavour, we trained an expert panel to identify characterising flavours by smelling. Methods: An expert panel (n=18) evaluated the smell of 20 tobacco products using self-defined odour attributes, following Quantitative Descriptive Analysis. The panel was trained during 14 attribute training, consensus training and performance monitoring sessions. Products were assessed during six test sessions. Principal component analysis, hierarchical clustering (four and six clusters) and Hotelling's T-tests (95% and 99% CIs) were used to determine differences and similarities between tobacco products based on odour attributes. Results: The final attribute list contained 13 odour descriptors. Panel performance was sufficient after 14 training sessions. Products marketed as unflavoured that formed a cluster were considered reference products. A four-cluster method distinguished cherry-flavoured, vanilla-flavoured and menthol-flavoured products from reference products. Six clusters subdivided reference products into tobacco leaves, roll-your-own and commercial products. Conclusions: An expert panel was successfully trained to assess characterising odours in cigarettes and roll-your-own tobacco. This method could be applied to other product types such as e-cigarettes. Regulatory decisions on the choice of reference products and significance level are needed which directly influences the products being assessed as having a characterising odour.

Chikungunya - community participation - Dengue - prevention - Zika
BACKGROUND: In the Caribbean, mosquito-borne diseases are a public health threat. In Sint Eustatius, dengue, Chikungunya and Zika are now endemic. To control and prevent mosquito-borne diseases, the Sint Eustatius Public Health Department relies on the community to assist with the control of Aedes aegypti mosquito. Unfortunately, community based interventions are not always simple, as community perceptions and responses shape actions and influence behavioural responses Objective: The aim of this study was to determine how the Sint Eustatius population perceives the Aedes aegypti mosquito, mosquito-borne diseases and prevention and control measures and hypothesized that increased knowledge of the virus, vector, control and prevention should result in a lower AQ1 prevalence and incidence of mosquito-borne diseases.
METHODS: This study was conducted in Sint Eustatius island in the Eastern Caribbean. We combined qualitative and quantitative designs. We conducted interviews and focus groups discussions among community member and health professional in 2013 and 2015. We also conducted cross-sectional survey to assess local knowledge on the vector, virus, and control and prevention.
RESULTS: The population is knowledgeable;
DISCUSSION: In the context of Sint Eustatius, when controlling the Aedes population it may be a strategic option to focus on the household level rather than the community and build collaborations with households by supporting them when they actively practice mosquito 25 control. To further increase the level of knowledge on the significance of mosquito-borne diseases, it may also be an option to contextualize the issue of the virus, vector, prevention and control into a broader context.
CONCLUSION: As evidenced by the increasing number of mosquito-borne diseases on the island, it appears that knowledge amongst the lay community may not be transferred into 30 action. This may be attributed to the perception of the Sint Eustatius populations that mosquitoes and the viruses they carry are not a high priority in comparison to other health concerns.

Lifestyle intervention studies have shown that the development of cardiometabolic diseases can be partly prevented or postponed by the combination of a healthy diet and physical activity. Cardiometabolic diseases and their risk factors are particularly prevalent among individuals with low socioeconomic status and some ethnic minorities, and therefore these groups especially may benefit from participating in lifestyle interventions. Although individuals with low socioeconomic status and ethnic minorities could potentially benefit from lifestyle interventions, it seems that these groups are often not successfully reached for such interventions. Moreover, when they do participate in these interventions, they seem more likely to quit. The overall aim of this thesis was therefore to study opportunities for, and the effectiveness of, lifestyle interventions to reduce the risk of cardiometabolic diseases, targeting individuals with low socioeconomic status of different ethnic origins. To this end, this thesis reports two studies that identified opportunities for adapting lifestyle interventions to the target group’s needs, one study describing the process of adapting an effective lifestyle intervention (SLIM) into a new lifestyle intervention targeting individuals with low SES of different ethnic origins (MetSLIM) and two studies that determined the effectiveness of lifestyle interventions among the target group.
The aim of the study described in chapter 2 was to identify opportunities for adapting lifestyle interventions in such a way as to be more appealing for individuals with low socioeconomic status. The study provided insight into perspectives of groups with different socioeconomic positions regarding their current eating and physical activity behaviour; triggers for lifestyle change; and preferred ways to support lifestyle change. Data were gathered in semi-structured focus group interviews with adults with low socioeconomic status (four groups) and with adults with high socioeconomic status (five groups). In general, three key topics were identified, namely: current lifestyle is logical for participants given their personal situation; lifestyle change is prompted by feedback from their body; and support for lifestyle change should include individually tailored advice and could profit from involving others. The perceptions of the participants with low socioeconomic status were generally comparable to the perceptions shared by the participants with high socioeconomic status. Some perceptions were, however, especially mentioned in the low socioeconomic status groups. Participants with low socioeconomic status indicated that their current eating behaviour was sometimes affected by cost concerns. They seemed to be especially motivated to change their lifestyle when they experienced health complaints but were rather hesitant to change their lifestyle for preventive purposes. Regarding support for lifestyle change, participants with low socioeconomic status preferred to receive advice in a group rather than on their own. For physical activities, groups should preferably consist of persons of the same age, gender or physical condition.
The aim of the study described in chapter 3 was to identify how Turkish and Moroccan adults living in the Netherlands, aged 45 years and older, could be reached to participate in health checks for cardiometabolic diseases and follow-up (lifestyle) advice. In this study, questionnaire data were combined with interview data. This was done in order to use the narratives from the interviews to get a better understanding of the numbers that resulted from the questionnaire data. It turned out that both ethnic groups preferred an invitation from their general practitioner (GP) for a health check and preferred to fill out the health check questionnaire at the GP’s office or at home, on paper. They preferred to receive advice at individual level in relation to personal matters via either a physician or a specialised healthcare professional. Sixty-one percent of the Turkish respondents preferred to receive information in their native language, compared to 37% of the Moroccan respondents. Several participants mentioned a low proficiency in the local language as an explanation for their preference to fill out the health check questionnaire at home, to receive advice from an ethnicity-matched professional and to receive information in their native language. The results of this study suggested that the GP would be a promising contact to reach adults of Turkish and Moroccan origin for health checks or (lifestyle) advice. Furthermore, the findings suggested that it would be necessary to provide information in individuals’ native language to overcome language barriers and that (lifestyle) advice should be tailored towards the needs of the targeted individuals.
The insights gained into the needs and preferences of the target group – as described in chapter 2 and chapter 3 – were taken into account in the design of the MetSLIM intervention study. The MetSLIM study targeted individuals with low socioeconomic status of Dutch, Turkish and Moroccan origin. The MetSLIM study protocol was based on the SLIM study protocol. The SLIM study showed the beneficial effects of nutrition advice and physical activity promotion on the prevention type 2 diabetes, but drop-out was relatively high among low SES participants. Chapter 4 provides a detailed description of the development from the SLIM study protocol to the MetSLIM study protocol. Furthermore, this chapter gives insight into the obstacles encountered in developing the MetSLIM study to target individuals with low socioeconomic status of different ethnic origins. The new elements regarding the lifestyle intervention programme were: 1) additional group meetings about price concerns and social occasions with regard to a healthy diet; 2) ethnicity-matched dieticians; 3) gender-matched sports instructors; 4) all activities in the participants’ own neighbourhood; and 5) activities for women and men separately. The new elements regarding the study design, in order to study the effectiveness of the MetSLIM intervention programme, included: 1) from an university stetting to a community setting; 2) from a randomised controlled trial to a quasi-experimental study; 3) waist circumference – as a visible cardiometabolic risk factor – as main study outcome; 4) recruitment via GPs and in community centres; 5) translated study materials and ethnicity-matched research assistants involved in measuring; and 6) fewer measurements and measurements that could take place at different locations. Adaptations to the original SLIM study protocol were considered necessary in order to overcome practical barriers that hinder the target group’s participation; to suit the target group’s (cultural) needs; and to make it feasible to perform the study in a local (community) setting.
MetSLIM was not the only study set up based on the SLIM study. The SLIMMER study translated SLIM from a university setting to a real-world setting. The intervention was implemented in the public health and primary healthcare setting involving local GPs, practice nurses, dieticians, physiotherapists and sports clubs. The SLIMMER study did not target individuals with low socioeconomic status in particular; however, 52% of the study participants did have a low socioeconomic status, as determined by highest completed educational level. Chapter 5 describes how we explored the role of socioeconomic status in willingness to participate, programme attendance, programme acceptability, adherence to lifestyle guidelines, drop-out and effectiveness in the SLIMMER diabetes prevention intervention. The SLIMMER study was a randomised controlled trial, targeting 40- to 70-year-old adults at increased risk of type 2 diabetes, carried out in Apeldoorn and Doetinchem. The intervention group participated in a 10-month lifestyle programme: weekly training sessions were guided by a physiotherapist, and dietary advice was given by a dietician during 5–8 individual consultations and one group session. Measurements were carried out at baseline, after 12 months and six months after the active intervention period ended. The study showed that participation, attendance, acceptability, adherence, drop-out and effect of the SLIMMER study were mostly not affected by socioeconomic status. The SLIMMER study was able to reach the low socioeconomic status group as effectively as the higher socioeconomic status group, resulting in at least similar health benefits. The SLIMMER sample size was too small to study differences within the low socioeconomic status group, e.g. comparing the low vs. the least educated or comparing ethnic groups. Only 10% of the 316 SLIMMER participants had the lowest educational levels (no education or primary education) and only 11% had a foreign background.
The aim of the study described in chapter 6 was to measure the effectiveness of the MetSLIM intervention on waist circumference and other cardiometabolic risk factors, lifestyle and quality of life among 30- to 70-year-old adults with an elevated waist-to-height ratio. In the MetSLIM study, 220 individuals participated, of whom 40% had no education or only primary education and of whom 64% had a foreign background. MetSLIM had a quasi-experimental design with measurements at baseline and after 12 months. Participants were recruited in deprived neighbourhoods of Arnhem and Eindhoven via either their GP or in community centres. The intervention group participated in a 12-month lifestyle programme: an introductory group meeting was guided by the researcher, weekly physical activity lessons were guided by a sports instructor and dietary advice was given by an ethnicity-matched dietician (in total four hours of individual consultations and three group sessions). The study showed that the MetSLIM lifestyle intervention was effective in reducing waist circumference, other measures of obesity, total and LDL cholesterol, and quality of life. MetSLIM had a drop-out of 31%, which was higher than at 12 months in the SLIM study (10%) and SLIMMER study (13%), but comparable to drop-out in similar studies among ethnic minorities or low socioeconomic status populations.
Finally, in chapter 7, the main results of this thesis are described, followed by a discussion of methodological considerations, public health implications, suggestions for future research and the general conclusion. The adaptation process from SLIM to MetSLIM is discussed, including a reflection on the decision to use SLIM as a starting point and the decision to target three different ethnic groups at the same time. Moreover, difficulties in defining and selecting persons with low socioeconomic status and specific ethnic groups within research are addressed. As SLIMMER and MetSLIM proved that low socioeconomic status populations can be reached, and that their health can be improved when they participate in lifestyle interventions, it is suggested that further implementation should be considered. Insight should be gained into the ‘black box’ of lifestyle interventions; i.e. we should get to know what works for whom. Planned future research includes a process and economic evaluation of MetSLIM.
This thesis has shown that intensive combined lifestyle interventions can be effective in low socioeconomic status populations and identified possible adaptations to make lifestyle interventions more suitable for individuals with low socioeconomic status of Dutch, Turkish and Moroccan origin. The question is not whether a lifestyle intervention can be effective, but how diverse groups can be reached and benefit from it. For this purpose, further insight into the success of different adaptations for different target groups should be obtained to reveal the effective elements to reach, inspire and retain different low socioeconomic status populations and ethnic minorities with lifestyle interventions.

Background: Expert guidelines formulated by the World Cancer Research Fund and the American Institute for Cancer Research (WCRF/AICR) advised no use of dietary supplements for cancer prevention. However, it is unclear whether those recommendations also apply to populations at high risk for incident or recurrent colorectal tumors specifically, since dietary supplement use is ubiquitous in western countries where colorectal tumors are common. Furthermore, before the association between dietary supplement use and recurrence and survival in colorectal cancer patients can be examined, more information about the consistency of dietary supplement use is needed, as it is plausible that use varies over time after colorectal cancer diagnosis. This thesis focuses on the association between dietary supplement use and colorectal tumor risk and recurrence in the general population and in high-risk populations, and describes the consistency of use in patients who were diagnosed with colorectal cancer.
Methods and results: First, we conducted a systematic literature review with meta-analyses of observational studies about the association between dietary supplement use and colorectal cancer risk. Our findings suggested inverse associations between multivitamins (use versus no use: RR=0.92; 95% CI 0.87–0.97, calcium supplements (use versus no use: RR=0.86; 95% CI 0.79–0.95) and colorectal cancer risk, while the association for other supplements and colorectal cancer risk was inconsistent.
Second, we investigated the role of dietary supplements in recurrence of colorectal adenomas and advanced colorectal adenomas in a prospective cohort study of 565 patients with a history of sporadic colorectal adenomas. Dietary supplement was not associated with total adenoma recurrence (HR=1.03; 95% CI 0.79–1.34).
Third, dietary supplement use and colorectal adenoma risk was examined in a prospective cohort study among 470 individuals with Lynch syndrome. No associations were found between dietary supplement use (HR=1.18; 95% CI 0.80–1.73) and colorectal adenoma risk in these individuals.
Finally, in an ongoing prospective cohort study among incident colorectal cancer patients we evaluated whether dietary supplement use was consistent over time. Dietary supplement use was extensively assessed with a detailed self-administered questionnaire at diagnosis, six months and two years post-diagnosis. We observed that dietary supplement use among 160 colorectal cancer patients was common at all time points, but use was inconsistent from diagnosis to two years post-diagnosis.
Conclusion: The results in this thesis do not point toward a preventive nor a harmful role for dietary supplement use in colorectal tumor risk and recurrence in the general population and in high-risk populations for colorectal cancer. However, dietary supplement use appeared to be inconsistent over time after colorectal cancer diagnosis, and use should be repetitively assessed over time. Since dietary supplement use is rising in countries where colorectal tumors are prevalent and the incidence of colorectal tumors will increase due to screening practices, research on the role of dietary supplement use for primary or tertiary prevention of colorectal tumors should continue in which use should be repetitively and comprehensively assessed.

Dietary flavonoid intake is associated with reduced risk of cardiovascular diseases, possibly by affecting metabolic health. The relative potency of different flavonoids in causing beneficial effects on energy and lipid metabolism has not been investigated. Effects of quercetin, hesperetin, epicatechin, apigenin and anthocyanins in mice fed a high-fat diet (HF) for 12 weeks were compared, relative to normal-fat diet. HF-induced body weight gain was significantly lowered by all flavonoids (17–29 %), but most by quercetin. Quercetin significantly lowered HF-induced hepatic lipid accumulation (71 %). Mesenteric adipose tissue weight and serum leptin levels were significantly lowered by quercetin, hesperetin and anthocyanins. Adipocyte cell size and adipose tissue inflammation were not affected. The effect on body weight and composition could not be explained by individual significant effects on energy intake, energy expenditure or activity. Lipid metabolism was not changed as measured by indirect calorimetry or expression of known lipid metabolic genes in liver and white adipose tissue. Hepatic expression of Cyp2b9 was strongly downregulated by all flavonoids. In conclusion, all flavonoids lowered parameters of HF-induced adiposity, with quercetin being most effective.

Excessive salt intake is associated with hypertension and cardiovascular diseases. Salt intake exceeds the World Health Organization population nutrition goal of 5 grams per day in the European region. We assessed the health impact of salt reduction in nine European countries (Finland, France, Ireland, Italy, Netherlands, Poland, Spain, Sweden and United Kingdom). Through literature research we obtained current salt intake and systolic blood pressure levels of the nine countries. The population health modeling tool DYNAMO-HIA including country-specific disease data was used to predict the changes in prevalence of ischemic heart disease and stroke for each country estimating the effect of salt reduction through its effect on blood pressure levels. A 30% salt reduction would reduce the prevalence of stroke by 6.4% in Finland to 13.5% in Poland. Ischemic heart disease would be decreased by 4.1% in Finland to 8.9% in Poland. When salt intake is reduced to the WHO population nutrient goal, it would reduce the prevalence of stroke from 10.1% in Finland to 23.1% in Poland. Ischemic heart disease would decrease by 6.6% in Finland to 15.5% in Poland. The number of postponed deaths would be 102,100 (0.9%) in France, and 191,300 (2.3%) in Poland. A reduction of salt intake to 5 grams per day is expected to substantially reduce the burden of cardiovascular disease and mortality in several European countries.

Background: Hypertensive disorders of pregnancy (HDPs), including gestational hypertension and pre-eclampsia, are common obstetric complications associated with adverse health outcomes for the mother and child. It remains unclear how dietary intake can influence HDP risk. Objective: We investigated associations between prepregnancy dietary patterns and risk of HDPs. Design: We selected 3582 women participating in the Australian Longitudinal Study on Women's Health, which is an observational population-based study. Women were not pregnant at baseline in 2003 and reported at least one live birth between 2003 and 2012. Diet was assessed by using a validated 101-item food-frequency questionnaire in 2003, and factor analysis was used to identify dietary patterns. HDPs were assessed by using the question, "Were you diagnosed or treated for hypertension during pregnancy?" Generalized estimating equation models were used to estimate RRs (95% CIs) adjusted for dietary, reproductive, sociodemographic, and lifestyle factors. Results: During 9 y of follow-up of 3582 women, 305 women (8.5%) reported a first diagnosis of HDPs in 6149 pregnancies. We identified 4 dietary patterns labeled as meat, high-fat, and sugar; Mediterranean-style; fruit and low-fat dairy; and cooked vegetables. In the adjusted model, the meat, high-fat, and sugar, fruit and low-fat dairy, and cooked vegetable dietary patterns were not associated with HDP risk. The Mediterranean-style dietary pattern (characterized by vegetables, legumes, nuts, tofu, rice, pasta, rye bread, red wine, and fish) was inversely associated with risk of developing HDPs (quartile 4 compared with quartile 1: RR, 0.58; 95% CI, 0.42, 0.81). Conclusions: In this population-based study of Australian women, we observed an independent protective dose-response association between prepregnancy consumption of a Mediterranean-style dietary pattern and HDP risk. Additional studies are recommended to confirm our findings by prospectively examining whether the implementation of the Mediterranean-style dietary pattern before pregnancy has a role in the prevention of HDPs.

objective To investigate community adherence to recommended behaviours for proper deployment of solar-powered mosquito trapping systems (SMoTS) after 3- to 10-week use. methods Solar-powered mosquito trapping system, which also provided power for room lighting and charging mobile phones, were installed in houses in Rusinga Island, western Kenya. We used a structured checklist for observations and a semi-structured questionnaire for interviews in 24 homesteads. We also analysed the subject of 224 community calls to the project team for technical maintenance of SMoTS. results Most respondents cared for SMoTS by fencing, emptying and cleaning the trap. Our observations revealed that most traps were fenced, clean and in good working condition. A significantly higher proportion of community calls was lighting-related. Lighting was the main reason respondents liked SMoTS because it reduced or eliminated expenditure on kerosene. However, some respondents observed they no longer heard sounds of mosquitoes inside their houses. All respondents reportedly slept under insecticide-treated nets (ITNs) before receiving SMoTS. After receiving SMoTS, most respondents reportedly continued to use ITNs citing that the project advised them to do so. Some beach residents stopped using ITNs because they no longer heard mosquitoes or due to heat discomfort caused by lights. conclusion Electricity-related incentives played a greater role in encouraging adherence to recommended behaviours for proper deployment of SMoTS than the potential health benefits in the early stages of the intervention. Although energy-related financial incentives may play a role, they are insufficient to ensure adherence to health advice, even in the short term. Ongoing community engagement and research monitors and addresses adherence to recommended behaviours including continuation of current malaria control strategies.

Invasive species can have strong impact on the local ecosystem, not only substantial impact on the local ecosystem, but also on economy and human health. This review on marine alien species outlines aspects of prevention, eradication and control strategies. When managing invasive species, prevention is preferable and less costly than controlling species. Especially for marine environments, invasive species can disperse rapidly and can be particularly hard to detect.

Within the framework of the Interreg project ‘Gezonde Kas’ a decision support system (DSS) for Botrytis risk in tomato was developed. This report fi rst summarizes existing knowledge on botrytis in tomato. The quantitative relationships are subsequently laid down in computer code. This code formed the basis of a dynamic simulation model to predict the risk on botrytis in a tomato crop. The model requires input from the climate computer of the greenhouse, and can also manage input from manual measurements. The report describes when and how the model predicts a high spore pressure and an increased risk on Botrytis infection, on the basis of climate conditions in the greenhouse. The prediction is highly improved when the data from the regular measurement box (‘meetbox’) are extended with data from a grid of sensors, positioned on representative spots in the greenhouse. The use of the model is facilitated for growers by the addition of a graphical user interface (GUI). The functionality of the GUI is explained. The DSS is now commercially available for growers and advisors, and can be used with and without other products of the Gezonde Kas project

Background: Breast-feeding is protective against respiratory infections in early life. Given the co-evolutionary adaptations of humans and cattle, bovine milk might exert similar anti-infective effects in human infants. Objective: To study effects of consumption of raw and processed cow's milk on common infections in infants. Methods: The PASTURE birth cohort followed 983 infants from rural areas in Austria, Finland, France, Germany, and Switzerland, for the first year of life, covering 37,306 person-weeks. Consumption of different types of cow's milk and occurrence of rhinitis, respiratory tract infections, otitis, and fever were assessed by weekly health diaries. C-reactive protein levels were assessed using blood samples taken at 12 months. Results: When contrasted with ultra-heat treated milk, raw milk consumption was inversely associated with occurrence of rhinitis (adjusted odds ratio from longitudinal models [95% CI]: 0.71 [0.54-0.94]), respiratory tract infections (0.77 [0.59-0.99]), otitis (0.14 [0.05-0.42]), and fever (0.69 [0.47-1.01]). Boiled farm milk showed similar but weaker associations. Industrially processed pasteurized milk was inversely associated with fever. Raw farm milk consumption was inversely associated with C-reactive protein levels at 12 months (geometric means ratio [95% CI]: 0.66 [0.45-0.98]). Conclusions: Early life consumption of raw cow's milk reduced the risk of manifest respiratory infections and fever by about 30%. If the health hazards of raw milk could be overcome, the public health impact of minimally processed but pathogen-free milk might be enormous, given the high prevalence of respiratory infections in the first year of life and the associated direct and indirect costs.

BACKGROUND Hypertension has recently been identified as the leading risk factor for global mortality. This study aims to present the national prevalence of hypertension and prehypertension and, their determinants in Vietnamese adults. METHODS Nationally representative data were obtained from the National Adult Overweight Survey 2005. This one visit survey included 17,199 subjects aged 25–64 years, with a mean body mass index (BMI) of 20.7kg/m2. RESULTS The overall census-weighted JNC7 (the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure) defined prevalence of hypertension was 20.7% (95% confidence interval (CI) = 19.4–22.1); the prevalence of prehypertension was 41.8% (95% CI = 40.4–43.1). Hypertension and prehypertension were more prevalent in men. Higher age, overweight, alcohol use (among men), and living in rural areas (among women) were independently associated with a higher prevalence of hypertension, whereas higher physical activity and education level were inversely associated. Age, BMI, and living in rural areas were independently associated with an increased prevalence of prehypertension. Among the hypertensives, 25.9% were aware of their hypertension, 12.2% were being treated, and 2.8% had their blood pressure under control; among the treated hypertensives, 32.4% had their blood pressure controlled.

In the past few decades, farms have increased in size and the focus of management has changed from curative to preventive. To help farmers cope with these changes, veterinarians offer veterinary herd health management (VHHM) programs, whose major objective is to support the farmer in reaching his farm performance goals. The association between farm performance and participation in VHHM, however, remains unknown. The aim of this paper was to compare farm performance parameters between participants and nonparticipants in VHHM and to differentiate within participation to evaluate the possible added value of VHHM on the farm. Five thousand farmers received a questionnaire about the level of VHHM on their farm. Farm performance parameters of these 5,000 farms were provided. For all respondents (n = 1,013), farm performance was compared between participants and nonparticipants and within level of participation, using linear mixed and linear regression models. Farmers who participated in VHHM produced 336 kg of milk/cow per year more and their average milk somatic cell count (SCC) was 8,340 cells/mL lower than farmers who did not participate in VHHM. Participating herds, however, had an older age at first calving (+12 d), a lower 56-d nonreturn rate percentage (-3.34%), and a higher number of inseminations per cow (+0.09 inseminations). They also had more cows culled per year (+1.05%), and a lower age at culling (-70 d). Participants in the most-extended form of VHHM (level 3) had a lower SCC (-19,800 cells/mL), fewer cows with high SCC (-1.70%), fewer cows with new high SCC (-0.47%), a shorter calving interval (-6.01 d), and fewer inseminations per heifer (-0.07 inseminations) than participants in the least-extended form of VHHM (level 1). Level 3 participants, however, also had more cows culled per year (+1.74%) and a lower age at culling (-103 d). Discussing specific topics with the veterinarian (milk production, fertility, and udder health) had only marginal effects on improving the farm performance parameters related to those topics. Given the relevance of fertility on the farm and the focus on longevity by society, it is important to determine underlying reasons for the negative associations of these topics with participation in VHHM. A longitudinal study could provide answers to this. For now, veterinarians should be aware of the associations. The increased milk production and milk quality could help the marketing of VHHM to farmers.

Out-of-wedlock pregnancy among adolescents in sub-Saharan Africa is a major concern, because of its association with health, social, psychological, economic and demographic factors. This article describes the development of the Teenage Mothers Project, a community-based intervention to improve psychological and social well-being of unmarried teenage mothers in rural Uganda. We used Intervention Mapping (IM) for systematically developing a theory and evidence-based comprehensive health promotion programme. A planning group consisting of community leaders, teenage mothers, staff of a community-based organization and a health promotion professional was involved in the six steps of IM: needs assessment, programme objectives, methods and applications, intervention design, planning for adoption and implementation and planning for evaluation. The programme includes five intervention components: community awareness raising, teenage mother support groups, formal education and income generation, counselling, and advocacy. The intervention components are based on a variety of theoretical methods, including entertainment education, persuasive communication, mobilization of social networks and social action. In conclusion, IM facilitated the planning group to structure the iterative, bottom-up, participatory design of the project in a real-life setting and to use evidence and theory. The article provides suggestions for the planning of support interventions for unmarried teenage mothers.

Background: Schools are important settings for the promotion of a healthy diet and sufficient physical activity and thus overweight prevention. Objective: To assess differences in school nutrition environment and body mass index (BMI) in primary schools between and within 12 European countries. Methods: Data from the World Health Organization (WHO) European Childhood Obesity Surveillance Initiative (COSI) were used (1831 and 2045 schools in 2007/2008 and 2009/2010, respectively). School personnel provided information on 18 school environmental characteristics on nutrition and physical activity. A school nutrition environment score was calculated using five nutrition-related characteristics whereby higher scores correspond to higher support for a healthy school nutrition environment. Trained field workers measured children’s weight and height; BMI-for-age (BMI/A) Z-scores were computed using the 2007 WHO growth reference and, for each school, the mean of the children’s BMI/A Z-scores was calculated. Results: Large between-country differences were found in the availability of food items on the premises (e.g., fresh fruit could be obtained in 12%-95% of schools) and school nutrition environment scores (range: 0.30-0.93). Low-score countries (Bulgaria, Czech Republic, Greece, Hungary, Latvia and Lithuania) graded less than three characteristics as supportive. High-score (=0.70) countries were Ireland, Malta, Norway, Portugal, Slovenia and Sweden. The combined absence of cold drinks containing sugar, sweet snacks and salted snacks were more observed in high-score countries than in low-score countries. Largest within-country school nutrition environment scores were found in Bulgaria, Czech Republic, Greece, Hungary, Latvia and Lithuania. All country-level BMI/A Z-scores were positive (range: 0.20-1.02), indicating higher BMI values than the 2007 WHO growth reference. With the exception of Norway and Sweden, a country-specific association between the school nutrition environment score and the school BMI/A Z-score was not observed. Conclusions: Some European countries have implemented more school policies that are supportive to a healthy nutrition environment than others. However, most countries with low school nutrition environment scores also host schools with supportive school environment policies, suggesting that a uniform school policy to tackle the “unhealthy” school nutrition environment has not been implemented at the same level throughout a country and may underline the need for harmonized school policies.
