School-based interventions on childhood obesity: a meta-analysis.

Over the past decade, childhood obesity has been recognized as a growing health problem worldwide. It is a predictor of adult obesity and is closely related to chronic lifestyle diseases.

This paper aims to evaluate the effectiveness of school based programs in the prevention and management of childhood obesity.

A comprehensive literature search was conducted in a clinical control study of school-based intervention for RCT and childhood obesity, published between 1995 and 2007. The papers included in the meta-analysis were ORs or articles with a standardized mean difference and their 95% CI. Reports can be calculated from existing data

Meta-analysis showed that participants had a significant protective effect on overweight and obesity in the school intervention program compared to the control group (OR = 0.74, 95% CI = 0.60, 0.92). More than a year of intervention has a higher OR to reduce the prevalence of obesity. However, interventional planning was not effective in reducing BMI compared to control treatment, and the weighted mean difference was -0.62 (95% CI = -1.39, 0.14).

This meta-analysis shows that there is convincing evidence that school-based interventions are at least short-term in reducing the prevalence of childhood obesity. Long-term plan is more effective than short-term plan

In systematic review and meta-analysis, to determine the impact of school-based physical activity intervention on children's body mass index (BMI), Harris and colleagues said that increasing the number of schools is necessary for current population-based policies I have concluded. Sports Activities Significant impact on the incidence of childhood obesity. Meta-analysis showed that BMI was not ameliorated by physical activity intervention. In contrast, Swedish studies by Marcus et al. Determined that school-based intervention could reduce obesity in children aged 6-10 years and may affect family eating habits. In a study of 3,135 men and women, we found that the prevalence of obesity and overweight decreased by 3.2% in schools that attempted intervention.

Economics provides several useful tools for the study of childhood obesity: insight into the economic causes and outcomes of obesity, clarification of the reasons for government intervention in the market, prevention or alleviation of obesity Use of cost-benefit analysis for policy comparison. This article summarizes the latest research in each field. Finally, the impact on health policy was discussed. In recent decades, actual food prices (food prices adjusted for inflation based on all goods and services) are falling sharply. For example, between 1990 and 2007, the actual price of a 2 liter Coca-Cola bottle fell by 34.89%, and the actual price of a cheese quarter bottle from McDonald's fell by 5.44% . 3 Between 1981 and 1994 several studies have shown that the decline in food prices accounts for 41 to 43% of the youth's increase in body mass index (BMI).
