Preliminary Results of the Planet Nutrition Program on Obesity Parameters in Mexican Schoolchildren: Pilot Single-School Randomized Controlled Trial.

ABSTRACT: School-based obesity prevention programs are key to promoting healthy habits. The aim of this study was to evaluate the effect of the Planet Nutrition program on BMI z-score and other parameters compared to a control group of Mexican schoolchildren after 9 weeks of intervention. The effect of the summer holidays on the BMI z-score was also evaluated at 23 weeks. A pilot randomized controlled trial design was used and 41 schoolchildren were randomized (21 intervention group and 20 control). The program included 18 nutrition education sessions, 20 physical activity classes and six brochures for parents. At 9 weeks, no significant differences were found between the intervention and control groups in the change in BMI z-score (-0.11, 95% CI -0.23, 0.01). Significant differences were observed in some secondary outcomes: body fat percentage (-1.72, 95% CI -3.42, -0.02), waist circumference (-3.45, 95% CI -5.55, -1.36), physical activity (0.44, 95% CI 0.01, 0.88) and nutrition knowledge (1.15, 95% CI 0.27, 2.03). Summer holidays negatively affected the BMI z-score in both groups, reducing the difference observed between groups at 9 weeks (-0.07, 95% CI -0.22, 0.07). The Planet Nutrition program showed favorable effects in some obesity and lifestyle parameters in the short term.

Project description:Existing evidence on the role of sociodemographic variables as risk factors for overweight and obesity in school-aged children is inconsistent. Furthermore, findings seem to be influenced by the obesity definition applied. Therefore, this study aimed to investigate if school sociodemographic indicators were associated with weight status in Irish primary schoolchildren and whether this association was sensitive to different obesity classification systems.A nationally representative cross-sectional sample of 7542 Irish children (53.9% girls), mean age 10.4 (±1.2SD) years, participating in the Childhood Obesity Surveillance Initiative in the 2010, 2012/2013 or 2015/2016 waves were included. Height, weight and waist circumference were objectively measured. Five definitions of obesity were employed using different approaches for either body mass index (BMI) or abdominal obesity. Associations between overweight and obesity and sociodemographic variables were investigated using adjusted multilevel logistic regression analyses.Children attending disadvantaged schools were more likely to be overweight and obese than their peers attending non-disadvantaged schools, regardless of the obesity classification system used. Associations remained significant for the BMI-based obesity definitions when the sample was stratified by sex and age group, except for boys aged 8-10.5 years. Only boys aged ?10.5 years in disadvantaged schools had higher odds of abdominal obesity (UK 1990 waist circumference growth charts: OR?=?1.56, 95%CI?=?1.09-2.24; waist-to-height ratio: OR?=?1.78, 95%CI?=?1.14-2.79) than those in non-disadvantaged schools. No associations were observed for school urbanisation level.School socioeconomic status was a strong determinant of overweight and obesity in Irish schoolchildren, and these associations were age- and sex-dependent. School location was not associated with overweight or obesity. There remains a need to intervene with school-aged children in disadvantaged schools, specifically among those approaching adolescence, to prevent a trajectory of obesity into adult life.

Project description:BackgroundWith the epidemic of childhood obesity, there is national interest in state-level school policies related to nutrition and physical activity, policies adopted by states, and relationships to youth obesity.PurposeThis study develops a comprehensive state-level approach to characterize the overall obesity prevention policy environment for schools and links the policy environments to youth obesity for each state.MethodsUsing 2006 School Health Policies and Programs Study (SHPPS) state data, qualitative and quantitative methods were used (2008-2009) to construct domains of state-level school obesity prevention policies and practices, establish the validity and reliability of the domain scales, and examine their associations with state-level obesity prevalence among youth aged 10-17 years from the 2003 National Survey of Children's Health.ResultsNearly 250 state-level obesity prevention-policy questions were identified from the SHPPS. Three broad policy topic areas containing 100 food service and nutrition (FSN) questionnaire items; 146 physical activity and education (PAE) items; and two weight assessment (WA) items were selected. Principal components analysis and content validity assessment were used to further categorize the items into six FSN, ten PAE, and one WA domain. Using a proportional scaled score to summarize the number of policies adopted by states, it was found that on average states adopted about half of the FSN (49%), 38% of the PAE, and 17% of the WA policies examined. After adjusting for state-level measures of ethnicity and income, the average proportion of FSN policies adopted by states was correlated with the prevalence of youth obesity at r =0.35 (p=0.01). However, no correlation was found between either PAE or WA policies and youth obesity (PAE policies at r =0.02 [p=0.53] and WA policies at r =0.16 [p=0.40]).ConclusionsStates appear to be doing a better job adopting FSN policies than PA or WA policies, and adoption of policies is correlated with youth obesity. Continued monitoring of these policies seems to be warranted.

Project description:BACKGROUND:The Nepal School Meals Program reached 600,000 schoolchildren in basic education in 2017 and plays a key role in the government's strategy to increase children's academic and nutritional outcomes. A large part of the program is implemented through cash transfers with schools responsible for the school meal delivery. Home-grown school feeding, an approach in which local communities are given greater control over the school meals program and part of the food is sourced locally, may strengthen local ownership and improve meal quality, but there is a lack of evidence for impact. METHODS:This study piloted home-grown school feeding in 30 schools reaching nearly 4000 children in Sindhupalchok and Bardiya districts in Nepal with the aim to assess operations and outcomes in comparison to the regular cash-based school meals program. The study used a one-time post evaluation with a mixed methods approach. Qualitative data were collected through 12 focus group discussions and 28 key informant interviews with government and school staff, parents, cooks, cooperative members, World Food Programme representatives and other stakeholders involved in the pilot program. The quantitative part applied a quasi-experimental design and used cross-sectional data collected from 1512 children in 30 pilot and 30 control schools. RESULTS:The quantitative data indicated that children in the pilot schools had a significantly higher provision of midday school meals (+?19%; p?<?0.01) and a higher school meal quality in terms of dietary diversity (+?44%; p?<?0.01) and nutritional content (e.g. a 21%-points higher consumption of vitamin A-rich fruit and vegetables; p?<?0.01). The qualitative data identified key drivers of these positive outcomes as the use of standard meal options, capacity building of local stakeholders, strengthened community ownership and accountability mechanisms, and local food supply chains. Maintaining the observed gains would require a 20-33% increase in the current budget per school meal in addition to the cost of capacity building. CONCLUSIONS:This study for Nepal shows that home-grown school feeding strengthened operations of the school meals program and led to a significantly higher meal provision and quality of school meals.
