Abstract EN
Objective.
To evaluate the effectiveness of a 12-month multicomponent obesity prevention intervention.
Setting.
9 elementary schools in Santiago, Chile.
Subjects.
6–8 y old low-income children (N=1474).
Design.
Randomized controlled study; 5 intervention/4 control schools.
We trained teachers to deliver nutrition contents and improve the quality of PE classes.
We determined % healthy snacks brought from home, children’s nutrition knowledge, nutritional status, duration of PE classes, and % time in moderate/vigorous activity (MVA).
Effectiveness was determined by comparing Δ BMI Z between intervention and control children using PROCMIXED.
Results.
% obesity increased in boys from both types of schools and in girls from control schools, while decreasing in girls from intervention schools (all nonsignificant).
% class time in MVA declined (24.5–16.2) while remaining unchanged (24.8–23.7%) in classes conducted by untrained and trained teachers, respectively.
In boys, BMI Z declined (1.33–1.24) and increased (1.22–1.35) in intervention and control schools, respectively.
In girls, BMI Z remained unchanged in intervention schools, while increasing significantly in control schools (0.91–1.06, P=0.024).
Interaction group * time was significant for boys (P<0.0001) and girls (P=0.004).
Conclusions.
This intervention was effective in controlling obesity, but not preventing it.
Even though impact was small, results showed that when no intervention is implemented, obesity increases.
