The effects of health interventions on dietary habits and physical measurements

The objective of this study was to determine the effects of health interventions on dietary habits and physical measurements. This quasi-experimental intervention study was performed with health service clients. The individuals' dietary habits, anthropometric measurements and blood pressure (BP) were obtained and measured, and a Food Frequency Questionnaire was administered upon their enrollment in the service. Interventions included physical activity, nutritional education groups, and individual nutritional counseling. Effects were measured by repeating physical measurements and using the What's your diet like? test. A total of 167 participants (mean age=52.5 years, SD12.6 years; 92.8% women) were included in the study. Following the interventions, there was a reduction in systolic BP (P=0.02) and use of animal fats (P<0.01), as well as an increase in the percentages of individuals having a normal waist circumference and daily consumption of greens/vegetables and milk/dairy products (P<0.01). Participation in the interventions was effective in improving the clients' nutrition and health, demonstrating the importance of interventions that combine dietary practices and physical activity in the promotion of health.
