Effectiveness of a Program for Physical Activity and Healthy Eating Promotion in Hypertensives

Summary

The main purpose of this study is to evaluate the effectiveness of VAMOS program, a physical activity and healthy eating promotion program, in hypertensive from Recife-Pernambuco- Brazil. Approximately 90 subjects with a diagnosis of hypertension, under anti-hypertensive medication and classified as non-physically active, will be selected and randomly distributed into two groups: a change behavior group (CBG) and control group (CG). The CBG will participate of a change behavior program, entitled VAMOS - Active Life Improving Health, for 12 weeks and composed of a weekly meeting, in group, lasting about 90 minutes. In each weekly meeting, will be presented and discussed guidelines and strategies for practical physical activities in different fields and for adoption of a healthy diet in order that the level of physical activity and eating quality improve. The program will be evaluated by effectiveness, implementation and maintenance (initial and individual level) dimensions of RE-AIM framework. The effectiveness will be assessed from anthropometric measurements, body composition, eating habits, physical activity level, stages of self-change, self-efficacy, social support, quality of life and assessment of cardiovascular function at rest (clinic and home blood pressure, arterial stiffness, blood flow and flow-mediated dilation, heart rate and heart rate variability) before and after 12 weeks of intervention. The implementation will be assessed by identifying the extent to which the program will be conducted as planned. The maintenance, initial and at individual level, will be estimated from revaluations of all outcomes, as measured before and after the intervention, three months after the end of the program. For data analysis, in addition to descriptive statistics, two-way ANOVA for mixed models wil be applied for for within and between groups comparison, if the premises of this test are met. The level of significance that will be adopted is P\<0.05. All analyzes will be done at SPSS statistical package, version 17.0.
