ABSTRACT

OBJECTIVE: To describe the implementation and feasibility of the national healthcare guidelines on childhood obesity in a region with a high prevalence of overweight and obesity in children. DESIGN: Descriptive, implementation study. METHOD: The implementation of the guidelines took place in the borough Amsterdam West. In total, 17 general practitioners (GP) from the Academic General Practice Network (ANH) of the VU University Medical Center, Amsterdam, participated in the study, along with 19 child healthcare practitioners and 3 paediatricians. A number of measures were taken to promote implementation. Feasibility was evaluated using both qualitative and quantitative methods. RESULTS: The participating healthcare providers found the training in application of the guidelines and case study discussions useful. GPs found that their role as central caregiver was not feasible. All participants expressed a preference for child healthcare practitioners as the central caregiver. A total of 327 obese children were invited to attend the GP's surgery; only 65 of them participated in the study and only 28 children were monitored for a whole year. Collaboration agreements between involved healthcare providers were rarely fulfilled. CONCLUSION: Implementation of the national healthcare guidelines on childhood obesity in the current form appears not to be feasible in Amsterdam West, despite the many implementation-enhancing measures that were applied. It is questionable whether the national healthcare guidelines on childhood obesity in its current form can contribute to addressing the societal problem of overweight and obesity in children.

ABSTRACT

The purpose of this study was to examine the concurrent validity of the Personal Activity Monitor (PAM) accelerometer relative to the Actigraph accelerometer using oxygen consumption as a reference, and to assess the test-retest reliability of the PAM. Thirty-two fit, normal weight adults (aged 21-54) performed two activities, treadmill walking and stair walking, while wearing the PAM, the Actigraph and the Cosmed K4b(2). Correlation coefficients and agreement in absolute energy expenditure (EE) levels between PAM, Actigraph and Cosmed were calculated. The test-retest reliability was examined among 296 PAM's using a laboratory shaker. Intraclass correlation coefficients (ICC) and coefficient of variation (CV) were determined. Correlations for treadmill walking and stair walking, respectively, were r(2)=0.95 and r(2)=0.65 for PAM with Actigraph, r(2)=0.82 and r(2)=0.93 for PAM with VO(2) and r(2)=0.64 and 0.74 for Actigraph with VO(2). Both the PAM and Actigraph underestimated EE during treadmill and stair walking by a substantial amount. The test-retest reliability of the PAM was high [ICC=0.80; 95% confidence interval (CI) (0.28;0.92) and intra-CV=1.5%]. The PAM and Actigraph accelerometer are comparable in assessing bodily movement during treadmill and stair walking. The PAM is a valid device to rank subjects in EE and can be useful in collecting objective data to monitor habitual physical activity.

ABSTRACT

OBJECTIVE: To evaluate the effect of Go4it, a multidisciplinary group education programme for adolescents with overweight or obesity. DESIGN: Uncontrolled intervention study. METHOD: At the obesity outpatient clinic of the Transmural Research and Treatment Centre for Overweight and Obese Children of the VU University Medical Center, Amsterdam, The Netherlands, a group education programme was developed for adolescents (age 12-18 year) who are overweight or obese. Obese adolescents who were referred to the obesity outpatient clinic were asked to participate. During 7 sessions (one session every two weeks) the adolescents were educated on the health consequences of obesity, diet, physical activity, energy balance, improving self-esteem and how to handle bullying and other difficult situations. All sessions were held in groups of 8-10 adolescents. In addition, two sessions were organised for the parents concerning the health consequences of obesity, diet, and physical activity. Body weight and height, glucose tolerance (by an oral glucose tolerance test; OGTT), and insulin resistance were measured at enrolment into the Go4it programme and 6 months later. RESULTS: In total, 93 adolescents (39 boys, 54 girls) were included with a mean age of 3.9 (SD: 1.7) years. Of those, 69 adolescents (74%) attended at least 6 out of 7 sessions of the education programme. Stabilisation or reduction in obesity levels following completion of Go4it was achieved in 51 (74%) of these participants. 50 adolescents had a second OGTT. The BMI standard deviation score (BMI-sds) decreased by 4.3% for boys (p = 0.020) and 3.3% for girls (p = 0.017). Among girls, fasting blood glucose levels decreased by an average of 0.37 mmol/l (95% CI: 0.14-0.60) and insulin concentrations decreased by an average of 299 pmol/l (95% CI: 71-528). CONCLUSION: Participation in the Go4it education programme is accompanied by a stabilisation or reduction in the level of obesity and has favourable effects on glucose and insulin metabolism.

ABSTRACT

OBJECTIVE: To outline the rationale, objectives and strategies used in a systematically designed research programmme to study specific weight gain-inducing behaviours, their social-psychological as well as environmental determinants, and the effects of interventions aimed at the prevention of weight gain. DESIGN: The evidence for potential behavioural determinants and strategies to prevent weight gain was reviewed, and the methods applied within the Netherlands Research programme weight gain prevention (NHF-NRG) project were described. The project is designed according to the Intervention Mapping protocol. SETTING: The Netherlands. SUBJECTS: The main target groups are (a) adolescents (12-16 y) in secondary school, (b) young adults (20-40 y) at the workplace and (c) recently retired people (55-65 y) at home. INTERVENTIONS: Each intervention includes an individual component, in which computer-tailored information is provided. Additionally, interventions are aimed at changing environmental components. RESULTS: The short-term results of this project can be expected by the beginning of 2005. Guidelines for nationwide weight gain prevention, based on this research programme, will become available in 2007. CONCLUSIONS: Based on the few interventions that were evaluated to date, no robust conclusions can be drawn regarding the effectiveness of obesity prevention. The systematic and multidisciplinary design of the NHF-NRG programme enables the identification of potentially effective methods and strategies for the prevention of weight gain.

ABSTRACT

The effectiveness was examined of inactivity and weight loss as criteria to identify a frail subgroup within independently living elderly persons participating in the SENECA study (Survey in Europe on Nutrition and the Elderly, a Concerted Action). Eight-hundred-forty-nine participants (aged 75 to 80) from nine countries were classified in four subgroups: 1) inactive elderly (lowest tertile activity score: n = 204); 2) weight losing elderly (lowest quintile: * 6.3% weight loss over 4-5 years: n = 108); 3) both inactive and weight losing (n = 54); 4) neither inactive nor weight losing: reference (n = 483). Differences in health, physical functioning and nutritional characteristics between groups 1, 2 and 3 respectively, and the reference group were evaluated. Compared to the weight-stable, active reference group, both inactive, weight losing (group 3) and inactive subjects (group 1) reported significantly more chronic diseases (2.2 and 1.8 vs. 1.1), disabilities (81 and 80 vs. 43%), use of medications (both 2.3 vs. 1.1) and care services (26 and 21 vs. 6%), and a lower self-rated health (2.8 and 3.1 vs. 3.8), relative health (1.9 and 2.1 vs. 2.6), and physical performance score (17 and 18 vs. 22). In addition, inadequate micronutrient intake and biochemical deficiencies were more prevalent. Weight-losing elderly were not significantly different from the reference group with respect to these characteristics. Therefore, physical inactivity alone or in combination with weight loss seems to be a practical and inexpensive screening criterion for identifying a subgroup of elderly with less favourable health and nutritional characteristics and poorer physical functioning among non-institutionalised elderly.

ABSTRACT

OBJECTIVE: To examine the effects of 17 weeks of physical exercise and micronutrient supplementation on the psychological wellbeing of 139 independently living, frail, elderly subjects (inactive, body mass index < or =25 or experiencing weight loss). METHODS: Participants (mean (SD) age 78.5 (5.7)) were randomly assigned to: (a) comprehensive, moderate intensity, group exercise; (b) daily micronutrient enriched foods (25-100% recommended daily amount); (c) both; (d) neither. A social programme and identical regular foods were offered as attention control and placebo. RESULTS: At baseline, moderate to low but significant correlations were found between general wellbeing scores and physical fitness (r = 0.28), functional performance (r = 0.37), and blood concentrations of pyridoxine (r = 0.20), folate (r = 0.25), and vitamin D (r = 0.23) (all p values < or =0.02), but not with physical activity levels and other blood vitamin concentrations. General wellbeing score and self rated health were not responsive to 17 weeks of exercise or nutritional intervention. CONCLUSION: Psychological wellbeing in frail elderly people was not responsive to 17 weeks of intervention with exercise and/or micronutrient enriched foods. The moderate but significant correlations between wellbeing and physical fitness and several blood vitamin concentrations at baseline suggest that changes in wellbeing may occur after long term interventions.
