The purpose of this article is to describe the study design, protocol, and baseline results of the “Healthy Habits, Healthy Girls” program. The intervention is being evaluated through a randomized controlled trial in 10 public schools in the city of São Paulo, Brazil. Data on the following variables were collected and assessed at baseline and will be reevaluated at 7 and 12 months: body mass index, waist circumference, dietary intake, nutrition, physical activity, social cognitive mediators, physical activity level, sedentary behaviors, self-rated physical status, and overall self-esteem. According to the baseline results, 32.4% and 23.4% of girls were overweight in the intervention and control groups, respectively, and in both groups a higher percentage failed to meet daily recommendations for moderate and vigorous physical activity and maximum screen time (TV, computer, mobile devices). There were no significant differences between the groups for most of the variables, except age (p = 0.000) and waist circumference (p = 0.014). The study showed a gap in the Brazilian literature on protocols for randomized controlled trials to prevent obesity among youth. The current study may thus be an important initial contribution to the field.

“…those immediately after their completion -are unknown and any effect in the intervention group may have faded before the post-test measurement. Recent meta-analyses and reviews examining school-based obesity prevention programmes that focused on changing lifestyles found greater effects in longer interventions -those that lasted several years -and in those in which parents were involved (32)(33)(34) . The intervention evaluated in the present paper took 6 months at maximum and parents did not participate in it.…”

Objective: To study the effects of school lessons about healthy food on adolescents' self-reported beliefs and behaviour regarding the purchase and consumption of soft drinks, water and extra foods, including sweets and snacks. The lessons were combined with the introduction of lower-calorie foods, food labelling and price reductions in school vending machines. Design: A cluster-randomized controlled design was used to allocate schools to an experimental group (i.e. lessons and changes to school vending machines) and a control group (i.e. 'care as usual'). Questionnaires were used pre-test and post-test to assess students' self-reported purchase of extra products and their knowledge and beliefs regarding the consumption of low-calorie products. Setting: Secondary schools in the Netherlands. Subjects: Twelve schools participated in the experimental group (303 students) and fourteen in the control group (311 students). The students' mean age was 13·6 years, 71·5 % were of native Dutch origin and mean BMI was 18·9 kg/m 2 . Results: At post-test, the experimental group knew significantly more about healthy food than the control group. Fewer students in the experimental group (43 %) than in the control group (56 %) reported bringing soft drinks from home. There was no significant effect on attitude, social norm, perceived behavioural control and intention regarding the consumption of low-calorie extra products. Conclusions: The intervention had limited effects on students' knowledge and selfreported behaviour, and no effect on their beliefs regarding low-calorie beverages, sweets or snacks. We recommend a combined educational and environmental intervention of longer duration and engaging parents. More research into the effects of such interventions is needed.
