Background: The increased prevalence of overweight and obesity warrants preventive actions, particularly among people in transitional stages associated with lifestyle changes, such as occupational retirement. The purpose is to investigate the effect of a one year low-intensity computer-tailored energy balance programme among recent retirees on waist circumference, body weight and body composition, blood pressure, physical activity and dietary intake. Methods: A randomised controlled trial was conducted among recent retirees (N = 413; mean age 59.5 years). Outcome measures were assessed using anthropometry, bio-impedance, blood pressure measurement and questionnaires. Results: Waist circumference, body weight and blood pressure decreased significantly in men of the intervention and control group, but no significant between-group-differences were observed at 12 or at 24-months follow-up. A significant effect of the programme was only observed on waist circumference (-1.56 cm ( 95% CI: -2.91 to -0.21)) at 12 month follow up among men with low education (n = 85). Physical activity and dietary behaviours improved in both the intervention and control group during the intervention period. Although, these behaviours changed more favourably in the intervention group, these between-group-differences were not statistically significant. Conclusions: The multifaceted computer-tailored programme for recent retirees did not appear to be effective. Apparently the transition to occupational retirement and/or participation in the study had a greater impact than the intervention programme.

Background & aim Different non-invasive methods exist to evaluate total body fat in children. Most methods have shown to be able to confirm a high fat percentage in children with overweight and obesity. No data are available on the estimation of total body fat in non-obese children. The aim of this study is to compare total body fat, assessed by different methods in non-obese children. Methods We compared total body fat, assessed by isotope dilution, dual energy X-ray, skinfold thickness, bioelectrical impedance analysis, combination of these methods as well as BMI in 30 six to seven-year-old children. Results The children had a mean BMI of 16.01 kg/m2 (range 13.51–20.32) and five children were overweight according to international criteria. Different methods showed rather different absolute values for total body fat. Bland–Altman analysis showed that the difference between the DEXA method and isotope dilution was dependent on the fat percentage. Children with the same BMI show a marked variation in total body fat ranging from 8% to 22% as estimated from the isotope dilution method. Conclusion Non-invasive methods are presently not suited to assess the absolute amount of total body fat in 6–7 years old children.

Background. Social facilitation and meal ambiance have beneficial effects on food intake in healthy adults. Extrapolation to the nursing home setting may lead to less malnutrition among the residents. Therefore, we investigate the effect of family-style meals on energy intake and the risk of malnutrition in Dutch nursing home residents. Methods. In 2002 and 2003, a randomized controlled trial was conducted among 178 residents (mean age 77 years) in five Dutch nursing homes. Within each home, two wards were randomized into an intervention (n = 94) and a control group (n = 84). For 6 months, the intervention group received their meals family style, and the control group received the usual individual preplating services. Outcome measures were intakes of energy (kJ), carbohydrates (g), fat (g), and protein (g) and Mini Nutritional Assessment (MNA) score (0¿30). Results. The change in daily energy intake between the control and intervention group differed significantly (991 kJ; 95% confidence interval [CI], 504¿1479). The difference in intake of macronutrients was 29.2 g (95% CI, 13.5¿44.9) for carbohydrate, 9.1 g (95% CI, 2.9¿15.2) for fat, and 8.6 g (95% CI, 3.4¿13.6) for protein. The percentage of residents in the intervention group classified by the MNA as malnourished decreased from 17% to 4%, whereas this percentage increased from 11% to 23% in the control group

bioelectrical-impedance - mass index - fat - water - build
Methods: Anthropometric parameters were measured in addition to impedance (100 kHz) of the total body, arms and legs. Impedance indexes were calculated as height2/impedance. Arm length (span) and leg length (sitting height), wrist and knee width were measured from which body build indices were calculated. Total body water (TBW) was measured using deuterium oxide dilution. Extra cellular water (ECW) was measured using bromide dilution. Body fat percentage was determined using a chemical four-compartment model. Results: The bias of TBW predicted from total body impedance index (bias: measured minus predicted TBW) was different among the three ethnic groups, TBW being significantly underestimated in Indians compared to Chinese and Malays. This bias was found to be dependent on body water distribution (ECW/TBW) and parameters of body build, mainly relative (to height) arm length. After correcting for differences in body water distribution and body build parameters the differences in bias across the ethnic groups disappeared. The impedance index using total body impedance was better correlated with TBW than the impedance index of arm or leg impedance, even after corrections for body build parameters. Conclusions: The study shows that ethnic-specific bias of impedance-based prediction formulas for body composition is due mainly to differences in body build among the ethnic groups. This means that the use of 'general' prediction equations across different (ethnic) population groups without prior testing of their validity should be avoided. Total body impedance has higher predictive value than segmental impedance.
