RESUMO:

Background: There has been an increase in overweight prevalence, which constitutes an important public health problem in adolescents. In this sense, prevention interventions focused on the promotion of healthy habits may lead to better health behaviors, with more significant use of multimedia tools and other innovative technological resources, highlighting the Internet. Thus, cultural adaptation of interventions based on international technologies aimed at the prevention of overweight is placed as a feasible alternative considering the scarcity of national production for this type of intervention. Objectives: To evaluate the effects of an intervention using a computer program, via the web, adapted to the Brazilian reality (StayingFit Brasil), in the health parameters of adolescents enrolled in elementary schools of the public school of the city of Salvador, Bahia. Methods: A systematic review was carried out in accordance with the recommendations proposed by the Guide Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA), registry (# CRD42018089340). Relevant scientific articles were searched in MEDLINE / PubMed, Embase, Scopus, Lilacs, PsycINFO, Cochrane and MEDLINE / Ovid. Randomized clinical trials and quasi-experimental studies examining the effect of an intervention - using computerized feedback (website or CD-ROM) - on food consumption and anthropometric parameters in adolescents in the school environment were included. In addition, a cultural adaptation study was conducted following four of the five steps of Barrera et al (2013): (1) information gathering; (2) preliminary adaptation design, which included the participation of topical experts for preliminary evaluation of the original content of the intervention; (3) preliminary adaptation tests; (4) adaptation refinement. A web school-based 12-month trial examining 7th to 9th grade students was conducted under registration number RBR-7qgnbn. The students were from twelve schools belonging to the comprehensive public education system of Salvador, Bahia, Brazil. The schools’ students were randomly distributed into the intervention and control groups. The adolescents in the intervention group participated in StayingFit, an online programme designed to encourage and guide healthy eating habits and control body weight. Data on food consumption, anthropometry, physical activity level, and sedentarism were collected from all of the students at the beginning of and after the 12-month study. Sociodemographic and socioeconomic data were collected at baseline. Generalised estimating equations (GEEs) were used to evaluate the effect of the intervention. The analyzes were performed in the statistical package Stata, version 14.0. Results: After the analysis of the original and the translated versions by the topical experts, modifications were suggested in order to provide a better understanding of the phrases translated into Portuguese and also into the reality of the adolescents, in order to guarantee the semantic, idiomatic and experimental equivalence of the adapted program. Participants demonstrated to understand the content of the sessions, navigating easily and approving the layout of the virtual environment. The baseline data showed a high prevalence of overweight (14.4% overweight, 8.5% obesity), physical inactivity (87.6%) and sedentary lifestyle (59.1%). In addition, low prevalence of adolescents with regular consumption of fruits (18.8%) and vegetables / legumes (16.3%). At the end of the follow-up period, students in the intervention group had a 43% increased chance of regularly consuming beans (OR=1.43, 95% CIs=1.10-1.86) and a 35% decreased chance of regularly consuming soft drinks (OR=0.65, 95% CIs=0.50-0.84). No differences were found between the groups studied with regard to the anthropometric parameters. Conclusion: The process of cultural adaptation of the StayingFit program to Brazil was successful in developing an engaging and interactive intervention for adolescents of full-time public schools in Salvador/BA/Brazil. Despite these modest results, the implementation of a web intervention can be beneficial and help promote positive changes in adolescent eating habits.
