- Abstract
Objective: To evaluate the impact of a low-cost nutritional intervention in changing the lifestyle of adults.Design: Randomised clinical trial.Setting: Primary health-care centre in São José do Rio Preto, São Paulo State, Brazil.Subjects: We randomly assigned 104 adults (83 women and 21 men aged 30–65 years, body mass index 24–35 kg m−2, non-diabetic) into two groups: nutrition counselling and control. Each subject in the intervention group received three individualised nutritional counselling sessions during the first 6 months aimed at increasing intakes of fruits, vegetables and olive oil, reducing saturated fat and improving physical activity. Body composition, biochemical indicators and lifestyle were assessed at baseline and at 6 months and 1 year in both groups.Results: After 6 months of follow-up, body weight, waist circumference, diastolic blood pressure, fasting blood glucose, total and low-density lipoprotein cholesterol, total and saturated fat, and dietary energy and cholesterol levels showed a more significant decrease among subjects in the intervention group than in the control group (P<0.05). Moreover, the intervention group showed significantly greater improvement in each intervention goal, such as reduced intake of saturated fat and increased intakes of fruits, vegetables, fibre and olive oil (P<0.05). After 12 months of follow-up, most of the outcomes were maintained.Conclusions: The low-cost nutritional intervention programme improved serum lipids profile and weight control, and appeared to be feasible for use at a primary health-care centre in a developing country.
