    JMIR Research Protocols 8 (2019)4. - ISSN 1929-0748
    Background: The persistence of health inequalities within high-income societies such as the Netherlands indicates the importance of researching effective ways to reduce those inequalities. Multiple strategies for reducing health inequalities have been identified. Specifically targeting health-related behaviors among lower socioeconomic status groups is one of those strategies. All in all, it seems relatively clear what types of approaches in general lead to health-related behavior change. However, it is still unclear how these approaches, in interaction with context, trigger a specific desired change. In the Netherlands, the private funding organization, Fonds NutsOhra, funded 46 small-scale projects under the umbrella of the Healthy Futures Nearby program. The projects aim to reduce vulnerable families’ health deprivation by triggering lifestyle changes.

    Objective: This study aimed to outline and justify the protocol for the overall evaluation of the program. The evaluation aimed to find out to what extent and how the small-scale projects and approaches within the program affect (or not) health-related behaviors and improve perceived health.

    Methods: The approach to the overall evaluation of the 46 projects builds on a combination of 3 frequently used evaluation models; it is theory-based, realist informed, and uses a mixed methodology design. Methods include analysis of quantitative project data, document analysis, focus groups, and interviews. A study design has been drawn up that values and uses the multifaceted development of the projects and the influence this might have on implementation and project outcomes. Also, it respects the complex nature of the projects and is suited to studying health promotion mechanisms in depth. Finally, it optimizes the usage of all—quantitative and qualitative—project evaluation data available.

    Results: This study protocol included the design of at least 4 different studies. The results will hence provide information on (1) building and defining theories of change in health promotion practice, (2) mechanisms at work in promotion of healthy behavior among vulnerable families, (3) what works and what does not in professionals’ practices in health promotion among those vulnerable groups, and (4) what works and what does not in health promotion projects with a participatory approach. In addition, data will be collected on the overall effectiveness of the 46 initiatives. Data collection started in 2016. Data analysis is currently underway, and the first results are expected to be submitted for publication in 2019.

    Conclusions: This overall evaluation provides a unique opportunity. The diversity of projects allows for a study protocol that answers in greater depth questions of how specific health promotion approaches work while also elucidating their effectiveness in a more traditional way. Using a theory-based complexity-sensitive approach that is mainly realist informed, this study also provides an opportunity to see whether combining assumptions from different evaluation perspectives yields relevant information.
    Poverty-related diseases: factors that predict coping in two Cameroonian settings
    Makoge, Valerie ; Hogeling, Lette ; Maat, Harro ; Vaandrager, Lenneke ; Koelen, Maria - \ 2019

    In this paper, we explore the connection between poverty and health (poverty-related diseases: PRDs) by investigating the factors that play a role in how two groups of people in Cameroon cope with health challenges: workers in a large agro-industrial organization (living in ‘camps’) and students in two major universities (living on ‘campuses’). We investigated factors reported in the literature as being associated with coping, summarized under the ‘salutogenic umbrella’, as well as demographic, social and environmental factors. A total of 509 respondents from camps and campuses participated in this study. We used a combination of standardized and un-standardized survey instruments to measure coping. We used χ2 and ANOVA tests to investigate bivariate differences and multiple logistic regression analysis to determine which significant survey factors predicted coping. Our results showed expected and unexpected differences between the settings. Individual dispositional factors such as sense of coherence (SOC), self-efficacy (SE), subjective wellbeing and self-rated health differed significantly between the settings. Expected coping resources such as income and SE did not differ between non-copers and copers. Two factors emerged as predictors of coping: living environment (setting) and SOC. Our results highlight the need for a multidimensional perspective on poverty and also the need to apply the salutogenic approach in PRD research. In particular, the emphasis this approach puts on stressors and the capacity to employ a variety of resources to overcome stressors is a fruitful way to better understand PRDs and the importance of location-specific circumstances where poverty, health and diseases are connected.

    Barriers and Facilitators for Health Behavior Change among Adults from Multi-Problem Households: A Qualitative Study
    Nagelhout, Gera ; Hogeling, Lette ; Spruijt, Renate ; Postma, Nathalie ; Vries, Hein de - \ 2017
    International Journal of Environmental Research and Public Health 14 (2017)10. - ISSN 1660-4601 - 17 p.
    Multi-problem households are households with problems on more than one of the following core problem areas: socio-economic problems, psycho-social problems, and problems related to child care. The aim of this study was to examine barriers and facilitators for health behavior change among adults from multi-problem households, as well as to identify ideas for a health promotion program. A qualitative study involving 25 semi-structured interviews was conducted among Dutch adults who received intensive family home care for multi-problem households. Results were discussed with eight social workers in a focus group interview. Data were analyzed using the Framework Method. The results revealed that the main reason for not engaging in sports were the costs. Physical activity was facilitated by physically active (transport to) work and by dog ownership. Respondents who received a food bank package reported this as a barrier for healthy eating. Those with medical conditions such as diabetes indicated that this motivated them to eat healthily. Smokers and former smokers reported that stress was a major barrier for quitting smoking but that medical conditions could motivate them to quit smoking. A reported reason for not using alcohol was having difficult past experiences such as violence and abuse by alcoholics. Mentioned intervention ideas were: something social, an outdoor sports event, cooking classes, a walking group, and children’s activities in nature. Free or cheap activities that include social interaction and reduce stress are in line with the identified barriers and facilitators. Besides these activities, it may be important to influence the target group’s environment by educating social workers and ensuring healthier food bank packages.
    Health care costs attributable to overweight calculated in a standardized way for three European countries

    This article presents a tool to calculate health care costs attributable to overweight in a comparable and standardized way. The purpose is to describe the methodological principles of the tool and to put it into use by calculating and comparing the costs attributable to overweight for The Netherlands, Germany and Czech Republic. The tool uses a top-down and prevalence-based approach, consisting of five steps. Step one identifies overweightrelated diseases and age- and gender-specific relative risks. Included diseases are ischemic heart disease, stroke, hypertension, type 2 diabetes mellitus, colorectal cancer, postmenopausal breast cancer, endometrial cancer, kidney cancer and osteoarthritis. Step two consists of collecting data on the age- and gender-specific prevalence of these diseases. Step three uses the population-attributable prevalence to determine the part of the prevalence of these diseases that is attributable to overweight. Step four calculates the health care costs associated with these diseases. Step five calculates the costs of these diseases that are attributable to overweight. Overweight is responsible for 20–26 % of the direct costs of included diseases, with sensitivity analyses varying this percentage between 15–31 %. Percentage of costs attributable to obesity and preobesity is about the same. Diseases with the highest percentage of costs due to overweight are diabetes, endometrial cancer and osteoarthritis. Disease costs attributable to overweight as a percentage of total health care expenditures range from 2 to 4 %. Data are consistent for all three countries, resulting in roughly a quarter of costs of included diseases being attributable to overweight.

    Verbrede financiering is een thema dat in de afgelopen jaren snel aan populariteit gewonnen heeft. Vele organisaties werken eraan, of hebben er interesse voor. Het aantal publicaties op dit gebied is aanzienlijk. Het gaat daarbij aan de input zijde om financieringsbronnen, instrumenten en mechanismen die ten behoeve van het duurzaam beheer geld inbrengen (subsidies, belastingvoordelen, kredieten aandelen, obligaties; privaat, publiek, nationaal en internationaal). Aan de output zijde van het systeem betreft het de betaling voor de duurzame levering van goederen en diensten uit het ecosysteem en de markten – of andersoortige arrangementen - die daarmee samenhangen.

    This study examines the recent socio-economic history of a Bajau fishing village on the northwest coast of Sabah, a state in the federation of Malaysia. The character of maritime anthro pology and anthropology of fishing was discussed as well. The question is raised whether maritime anthropology and anthropology of fishing are meaningful specializations. This question was answered positively.

    The social analysis of Gayang was based on three theories of development i.e. of Mygdal, Pearse and Galjart. The socio-economic development in Gayang was seen in the light of these theories. The material on Gayang shows that these theories are only valid under particular conditions.

    The major concepts used in the analysis of Gayang were incorpo ration and scarcity. Incorporation was defined as an increase of the number of relations between the inhabitants of a local community and the wider society, as an intensification or an an institutionalization of these relations. Scarcity is usually defined as the relationship between supply and demand expressed in money. Because so much of the economic life of peasants has a value that cannot be expressed in money, labour has been used instead, despite its shortcommings.

    In order to understand the economic behaviour of small-scale fishermen some of the insights gained from peasant studies have proved useful. in this study Scott's "safety first" principle and "subsistence ethic" are used in conjunction with Moerman's in sight as to the expectation of entrepreneurial behaviour of peasants.

    The research problem has been defined as follows:
    1. Can a process of incorporation of Gayang into the wider society be identified? If yes, what is its character, what are the different processes involved and what are the causes?
    2. Did any change occur in the relative scarcity of resources and means of production? If yes, to what extend are they related to a process of incorporation, or should they be explained in a different way?
    3. What is the effect of incorporation and the change in the relative scarcity on the social organization of production and distribution?

    In the second chapter the history of Sabah, which has affected the developments of Gayang, is discussed. Before the history of Sabah is given, a brief history of the harbour principalities of Brunei and Sulu is presented, since Sabah fell under their jurisdiction prior to the colonial period. The nature of these harbour principalities, which form a special type, is examined and is used to explain the historical development of this region. The precolonial history is seen as the history of the perifery of these harbour principalities.

    Colonial rule in Sabah was introduced by the Chartered Company, a commercial firm. This changed the nature and increased the integration of Sabah in the world economy. After the Japanese occupation during the second world war, which in Sabah was particularly harsh, Sabah became a British Crown Colony, which after independence became a state in the federation of Malaysia. Sabah experienced rapid development in this period as indicated by the growth of the G.N.P. and improved its infra-structure, health service, education etc.

    The literature about the Bajau is reviewed in chapter three. Generally the Bajau seem to have been low status sea-nomads, owing alligiance to the different noblemen in the archipelago, especially in Sulu. On the northwest coast of Sabah they appear to have settled and to have been followers of islam for over two hundred years.

    Chapter four describes and analyses life in Gayang, especially focussing on the recent socio-economic history. The description starts with the significant features of the surroundings i.e. the river, the sea, the beach, mangrove swamps, land and communications. Household composition, leadership, the economic position of those households which fall into the lowest category with regard to the ownership of means of production, the role of the government, individualism and economic activities are treated. Nearly sixty percent of all households consist of parents and children only and if one includes households consisting of single individuals, households of couples without children and one parent families, this would amount to seventy nine percent. Households which consist of more than three generations form nine percent of all households.

    Leadership in Gayang is not linked to inherited titles and is not associated with status or any special lifestile. Leadership in Gayang is most clearly to be seen in fishing and is linked to ownership. The owner takes all the decisions and initiative. However it is not uncommon to find the leader of a fishing trip in the morning acting as a common crew member in an other fishing trip on the same day and vice versa.

    The economic position of those households which fall into the lowest category with regard to the ownership of means of production, is reviewed in some detail. Of these seventeen households, three are dependent on support from relatives in order to fulfil their daily needs. Two households can make ends meet but cannot save, and the rest like all other households save and invest.

    It seems that life in Gayang is characterised by individualistic behaviour. When parents and children live in the same house they may or may not form a single household. In the latter case, business transactions between the two households are normal. Parents do not expect to be supported by their children or other relatives unless they have no income and are unable to work.

    Most households are engaged in agriculture and fishing but crafts, gathering, trading, wage labour and migrant labour also play a - minor - role in economic life.

    Rice is primarily a subsistence crop, providing the staple food. Fishing provides most of the cash but home consumption takes precedence over the sale of fish.

    Striking features of the fishing industry in Gayang are the absence of middlemen, credit and indebtness, the short duration and standardization of the contracts between owner and crew and labour shortage. Fish is sold on the market by the fishermen's wives directly to the consumer. This income allows the fishermen to pay for their consumer good and to accumulate capital, which is used to buy their fishing gear. This fishing gear is paid for in cash.

    The number of men available in Gayang is only half of that needed to operate all nets simultaneously and as a consequence a con siderable part of the capital invested in nets cannot be made fully productive. It was concluded that the increasing incorporation of Gayang had resulted in a situation in which no longer the availability of the means of production limits the size of production but the availability of labour. The result has been a smaller scale of the production units because of an increased emphasis on the gill net which needs only two men to operate and the introduction of shared ownership of the more labour-intensive beach seines in order to develop more durable relations with the crew. Looking at the processes outlined in the theory of Mygdal, Pearse and Galjart we see some differences with the development processes in Gayang: marginalisation of a large portion of the population does not occur; it is unlikely that the control of resources is transferred to groups or individuals outside the village, there is no withdrawal into a subsistence economy and there is no emigration. It is hypothesized that the nature of the available technology in combination with some environmental fea tures are responsable for the increased demand for labour which cannot be supplied and therefore forms a complex of factors that must be conditional for the validity of the theories of Mygdal, Pearse and Galjart.
