Promoting fruit and vegetable consumption: Methodological protocol of a randomized controlled community trial

This study aimed to develop community educational activities in Brazilian primary health care settings. A randomized controlled community trial was conducted to encourage fruit and vegetable consumption (FV-RCT) in a representative sample of consumers aged 20 years or older in a Brazilian city. The fruit and vegetable consumption was classified according to the transtheoretical models stages of change, reflecting different degrees of readiness for change. The educational activities were based on the transtheoretical model and a problematizing-dialogic pedagogy, planned by an interdisciplinary team, using information collected in a qualitative pilot study. The actions were conducted over seven months, and baseline data were collected from 1483 participants. The educational strategies included workshops interspersed with motivational messages conveyed via postcard, interactive environment-based activities, and informative material. In the workshops, different techniques were used - conversation circles, image theatre, self-portraits, cooking and art as experience. The applied intervention based on the chosen theories implied in a refinement of the intervention, but, nevertheless, proved to be feasible for large population groups and to the scenario of health services. Thus, this interdisciplinary FV-RCT study represents an effort to advance methodological issues and provide theoretical subsidies for actions.

Coexistence of risk behaviors for being overweight among Brazilian adolescents

This study aimed to evaluate the magnitude of and the factors associated with the coexistence of risk behaviors for being overweight among Brazilian adolescents. This is a cross-sectional study with a representative sample of adolescents (mostly aged 13-15years) enrolled from public and private schools of Brazil in 2012. The co-occurring sedentary behavior and inadequate food consumption (regular intake of sugary and fried foods, and irregular consumption of fruits and vegetables-FV) was estimated using a Venn diagram. Sociodemographic, familial, and behavioral factors associated with the number of risk behaviors for being overweight were identified using an ordinal logistic regression analysis. Sedentary behavior was observed in 62.0% of adolescents. Regular intake of sugary or fried food was observed in 55.3% and 23.5% of adolescents, respectively, with 51.9% having an inadequate intake of FV. At least one risk behavior was reported in >90.0% of adolescents; 6.1% reported all 4. Being female, having a higher maternal education level, attending private school, not having breakfast or meals with parents regularly, eat watching television, and not practicing weekly leisure time physical activity were associated with an increased chance of having multiple risk behaviors. This study observed a high prevalence of coexisting of risk behaviors, which was associated with sociodemographic, familial, and behavioral factors. These findings may contribute to a clearer understanding of the associations between different behaviors among adolescents, and may be used to improve public health surveillance and to develop strategies that address multiple behaviors, in order to prevent overweight among adolescents.

Effectiveness of nutritional intervention in overweight women in Primary Health Care

Objective: To assess the effectiveness of nutritional intervention in overweight women undergoing Primary Health Care.Methods: An intervention study was conducted with overweight adult and elderly women aged 20 years or older (body mass index ≥25.0 kg/m² and ≥27.0 kg/m², respectively) who were subjected to 12 months of individual nutritional monitoring. The effectiveness of the intervention was assessed by dietary, health, and anthropometric indicators.Results: Most of the 71 individuals were adults with a low income and poor level of education. After the intervention, there was an increase in number of meals and in the frequency of breakfasting. Moreover, there were more fruits and vegetables consumed, in addition to a decrease in household availability of salt, sugar, oil, and fried foods consumption. An improvement in health and weight self-perception was observed, as well as a decrease in body mass and abdominal adiposity, in particular among those participating in several consultations (n >9).Conclusion: The proposed nutritional intervention was effective and viable for improving the care of overweight individuals and those suffering from destabilized comorbidities, and may be extended to other contexts.

Consumption of these foods was classified as: do not consume sweets and soft drinks regularly; consume sweets or soft drinks regularly; and consume sweets and soft drinks regularly. Its association with sociodemographic information, eating habits, and family contexts were investigated via multiple ordinal regressions. Regular consumption of sweets and/or soft drinks was reported by 19.2% and 36.1% of adolescents, respectively, and higher prevalence was associated with female gender, age 14-15 years, higher maternal education, not living with the mother and father, not eating meals with the parents, eating while watching TV, and longer TV time. Nearly one-fifth of adolescents regularly consumed sweets and soft drinks, which was associated with socio-demographic and behavioral factors that should be targeted in order to improve their food consumption.
