Overweight and obesity in children and adolescents (2011) In Mexico 29.3% of the total population (33 millions) are children (0 to 14 years old) (INEGI 2010) The National Survey on Health and Nutrition (ENSANUT 2012) shows that: 34.4% of children from 5 to 11 years old have excessive weight 19.8% overweight and 14.6% obesity Between 2006 and 2012 these numbers have not increased 35% of teenagers from 12 to 19 years old, present overweight or obesity. The obesity rate is higher in women (23.7%) that in men (19.6%) Between 2006 and 2012 the overweight and obesity increase in 5% -Instituto Nacional de Estadística y Geografía.

Causes Physical activity. ENSANUT 2012 More than half of children between 10 and 14 years old have not carried out any formal physical activity, in the last 12 months previous to the survey. Only 33% of surveyed children stay less than two hours (maximum recommended time) in front of the screens. School diet Several studies have indicated that the Mexican students consume an average of 433 calories in the school snack, with a change in the consumption pattern: Children 1 to 4 years old increased calories intake from 165 to 297 kcal. Students 5 to 11 years old increased calories intake from 190 to 343 kcal. Energy average allowance of lunch must be of 17.5% of total energy: Pre-school 227 kcal +/-5% Primary school 276 kcal +/-5% Secondary school 382 kcal +/-5% Rivera-Dommarco J, et al.

As an answer of Mexico’s government, the Ministry of Health, started the National Agreement for Nutritional Health: Strategy against overweight and obesity (ANSA), January 2010. Both government and society must act to combat the epidemic of obesity National policies should encourage and provide opportunities for increased physical activity and improve the availability and accessibility of healthy foods The severity of the problem calls for the participation and responsibility of different government sectors, civil society, private sector as well as individuals and families. Strategies and actions for overweight and obesity prevention in Mexico
Strategies and actions in school setting School as important setting to promote healthy nutrition and physical activity habits Action Plan for Schools Health Promotion and Education Regular physical activity Availability and access to healthy food and beverages in schools Action Plan for Schools Health Promotion and Education Regular physical activity Availability and access to healthy food and beverages in schools Guidelines on Nutrition Standards for Foods and Beverages offered in Schools
Implementation of guidelines Gradually, (by school years) to allow a sustained and continuous change, enabling acceptance and adjustment of all actors Energy per portion <= 140 kcal Total fats <= ≤ 40% Energy per portion < = 130 kcal Total fats <= ≤ 40% Reduction of sugar, saturated and trans fats, sodium and fiber Energy per portion <= 130 kcal Total fats <= ≤ 35% More reduction of sugar, saturated and trans fats and sodium Stage I (School year 2010-2011). Stage II (School year 2011- 2012) Stage III (Starting from school year 2012)
Closure of stage II

Daily consumption: 1) Vegetables and fruits, 2) Plain water, 3) Prepared food Recommendations for school snack Energy Value 15% to 20% (17.5% average) 25-30% fats, 55-60% carbohidrates, 10-15% protein Saturated fats <10%, trans fat <1%, Added sugars <10%, salt < 5g To include daily: One or more portions of vegetables and fruits One portion of prepared food according to nutritional criteria Plain water Twice a week: one portion ok semi or skimmed milk or yogurt, fermented dairy products, juices non caloric sweeteners free Once a week: salty snacks, cookies, candies and desserts that fulfill the nutritional criteria

Main results Most of the members of the educational community (teachers, parents and students) knew about the general guidelines (77.14%). 75.46% of school vendors fulfilled the general guidelines. The same beverages were offered in pre, primary and secondary schools. There was some resistance from parents used to sending a school snack with a high energy content and sugared beverages.

Conclusions During these evaluations we can observe the following: In the first stage there was resistance from the vendors because they didn’t have the educational materials and there is also a lack of cooperation from the parents. In the second stage there is more participation of all actors, the vendors had the educational material, they agreed to follow the guidelines because they knew them and parents take into consideration the guidelines to prepare the lunch of their chidren.
Challenges of the guidelines To put emphazis in students and teachers about the importance of physical activity, by means of educative campaigns which underline their benefits. To increase the participation of parents for motivating physical activity. To intensify the supervision of sale of food and beverages by the committees and principals
