Impact of an education intervention using email for the prevention of weight gain among adult workers

Abstract

Objective: To evaluate the impact of a worksite intervention to prevent weight gain among adult workers. Design: A controlled community trial was performed by dividing the workers into two groups: intervention group (IG) and control group (CG). The theoretical framework applied was Intervention Mapping Protocol and the intervention was implemented through interactive software for weight self-monitoring. To evaluate the impact of the intervention, the differences in weight, BMI and waist circumference between the IG and CG were assessed before and 6 months after the intervention by regression models. Additionally, the sustainability of the intervention was evaluated at 12 months after the intervention. Settings: São Paulo, Brazil. Subjects: Four companies; 281 workers for the analysis of effectiveness and 427 for the analysis of sustainability. Results: The intervention resulted in significant reductions in weight, BMI and waist circumference in the IG compared with the CG. The impact of the intervention on IG individuals' body weight was 20?73 kg, while the weight of CG individuals increased. IG individuals with adequate initial weights did not show significant variations, while those who were overweight demonstrated a significant reduction in body weight. The intervention resulted in a reduction of 0?26 kg/m 2 in BMI and 0?99 cm in waist circumference, and the sustainability analysis after 12 months showed a continued reduction in body weight (20?72 kg). Conclusions: The behavioural intervention was effective, resulting in weight maintenance among participants with adequate initial weight and in significant reductions among those who were overweight. More research on longer-term weight maintenance is needed.

Quanto à avaliação da presente revisão sistemática, as principais limitações foram a utilização de apenas uma base de dados e a dificuldade no método de análise dos artigos devido às diferenças em seus aspectos metodológicos.…”
