简要总结
Childhood obesity is a major global public health problem. Several strategies have been implemented to reduce the high prevalence, the most cost-effective of which were those that focused on the school environment. Although there is vast research that focus on interventions that address obesity through interventions to improve schoolchildren diets and physical activity level in many countries of the Latin American region, there is lack of evidence of the effectiveness of multicomponent interventions that aim to reduce the prevalence of obesity among schoolchildren in the Paraguayan context.
详细描述
Nutritional education and physical activity. Interventions that promote healthy eating and lifelong physical activity in schoolchildren through school programs aim to equip children with knowledge, attitudes and behavioral skills to help them establish and maintain a healthy lifestyle.
Poor diet quality has been identified as one of the main factors contributing to the obesity epidemic. Research has shown that a diet that includes the recommended servings of fruits and vegetables (VF) reduces morbidity and mortality from non-communicable diseases (NCDs) and has also been linked to a lower risk of adiposity. Therefore, the need to promote the consumption of VF from an early age through effective programs.
The interventions in Physical Activity have shown effective results in the decrease of BMI, the thickness of the skin folds and the percentage of fat mass in school-age children. Taking into account that currently the schoolchildren have decreased the amount of time dedicated to games, sports or other types of movement and the hours of sedentary life and in front of the screens (computers, tablets, television, mobile phones, others) have increased.
It is necessary to promote the performance of physical activity in the school environment through permanent programs that contribute to improving the physical condition of children, complying with daily recommendations.

盲法说明
Three lists of schools were built, according to type of institution and area where the school is located. The first list corresponded to rural public schools, the second to urban public schools and the last to urban private schools.
Each of the lists contained the type of institution (public / private), the area where it is located (urban / rural), the name of the school and the district to which it belongs. The schools were masked with an identifier number in order to avoid bias during the assignment to the groups (intervened / control). Schools were selected using a computer based list (...)
