Detailed Description
Cardiovascular disease (CVD) is a leading cause of mortality worldwide and Colombia is not an exception. Epidemiological studies have demonstrated that CVD risk factors are identifiable in childhood and they are predictor of CDV risk in adulthood. Worldwide, CDV primary prevention that begins in childhood is identified as a strategy that decreases the burden of this disease.
Programs developed in educational communities (EC), that include in their planning and implementation students, teachers and parents, with training to food personnel, are the most effective strategies to create healthy school environments and reduce the burden of chronic diseases. However recent studies that evaluate physical activity through accelerometers have not shown effectiveness.
In 2009, the Si! program and Fundación CardioInfantil performed a randomized and controlled community trial in facilities of the Colombian Family welfare Institute, ICBF, from Usaquen locality in Bogotá, finding that a pedagogical intervention (PI) in preschool children, their parents and teachers is effective in improving knowledge, attitudes and habits towards an active lifestyle and healthy diet.
The construction of the proposed intervention is based on the best available evidence about programs, policies and practices that positively impact in healthy eating and physical activity habits in EC.
The objectives of this project are to evaluate changes in healthy foods consumption and energy expenditure in children from kindergarten to second grade of elementary school that receives pedagogical intervention (PI) adapted to its context, compared to another EC that develops its habitual curriculum. In addition, this study evaluates changes on cardiovascular risk factors in children. Also, it evaluates changes in healthy foods consumption in their parents and teachers.

Intervention / Treatment |
---|---|
Experimental: Investigational
An education intervention was implemented in 5 schools including 516 children, 360 parents and 240 teachers. The Pedagogical Intervention last two and a half years. In children, the intervention included class activities (1/week) and the use of educational materials for the development of pedagogical activities (posters and educative guide). In parents included 3 workshops/year (2 hours each) about the areas of the intervention; sending healthy notes (1/month) and celebration of healthy family day (1/year). In teachers included 3 workshops/year (2 hours each) about the areas of the intervention; planning and realization of pedagogical activities to develop with the students (1/week) and follow-up visits to school (1/month). |
The educational intervention helped to increase the knowledge of attitudes, and habits of healthy lifestyle in children, parents and teachers and it was based on health promotion models and social cognitive theory, to be articulated with the Institutional Educational Project through the pedagogical component that integrates three areas, physical activity, healthy eating, and the knowledge of the body and the heart with the dynamics of the educative community. The program covered self-care of the body and heart, healthy diet, and physical activity |
Active Comparator: Control
The control group consisted of 4 schools including 354 children, 305 parents and 110 teachers. The activities in control group last two and a half years. Children received the standard curriculum in health and physical activity of the national Ministry of Education. In parents and teachers included 3 workshops/year (2 hours each) about the first aid and accident prevention. |
The control group did not receive an educational intervention in areas of physical activity, healthy eating, and the knowledge of the body and the heart.
Instead, children received the standard curriculum in health and physical activity of the national Ministry of Education.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in active energy expenditure in children
Time Frame: Baseline and 2.5 years
|
The energy expenditure (Kilocalories/day), in children from Kindergarten to grade 2 of elementary school, generated by physical activity was evaluated using accelerometers during 4 consecutive days, 24hours/day (2 weekend days and two schooldays) through an Actiheart® 4 type accelerometer. Possible differences between changes in active energy expenditure means was assessed using test t-test. Multi-variable models were performed to adjust for potential con-founders. |
Baseline and 2.5 years
|
Changes in healthy foods consumption in children
Time Frame: Baseline and 2.5 years
|
A food frequency survey (ENSIN 2010) was used in children from Kindergarten to grade 2 of elementary school. Healthy foods consumptions were defined as the accomplishment of 3-4 of the 4 measured components (intake of Fruits and vegetables ≥3 times a day, Fiber: ≥3 times a day, Fish: ≥2 times a week, Sugary beverages: ≤ 1 time a day). Possible differences between changes in the proportion of children with healthy foods consumption was assessed using chi2 test. Multi-variable models were performed to adjust for potential con-founders. |
Baseline and 2.5 years

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Changes in the Body Mass Index in children
Time Frame: Baseline and 2.5 years
|
Using the Quetelet index, that considers the BMI as the relationship between the body weight given in kg and the square size taken in meters. Possible differences between changes in BMI means was assessed using test t-test. Multi-variable models were performed to adjust for potential con-founders. |
Baseline and 2.5 years
|
Changes in the perimeter of the waist in children
Time Frame: Baseline and 2.5 years
|
Using a tape measure on the skin just above the iliac crest, in feet position.
