Barriers and Enablers That Influence Overweight/Obesity/Obesogenic Behavior in Adolescents From Lower-Middle Income Countries: A Systematic Review.

ABSTRACT

BACKGROUND: Overweight/obesity during adolescence in lower-middle income countries has become a public health problem with consequences in adulthood. Inadequate dietary habits, poor diet quality, sedentary behavior, and parental obesity have been reported. OBJECTIVE: To describe management of obesity-like food habits and behavior of adolescents from lower-middle income countries with respect to what keeps them using this diet (barriers) and what helps them avoid it (enablers). METHODS: Systematic review of the literature related to obesity and food intake of adolescents conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). RESULTS: We classified 11 eligible studies describing the barriers to and enablers of the management of obesity-like food intake and obesity lifestyle. The dual burdens of malnutrition and increased urbanization have been observed. There is preference for processed food, dietary habits, and obesity-like food intake and sedentary behavior. Barriers to managing body weight gain included mostly consumption of fast-food and snack food, less vegetable and fruit intake, skipping meals, and sedentary behavior. Enablers of managing body weight gain included changes in nutritional habits, perception of the consumption of healthy food, physical activity, and engagement in programs to change lifestyle. CONCLUSION: The globalization of the fast food industry has provided an obesogenic environmental stimulus for adolescents in lower-middle income countries.
