Brief summary

The study aims at evaluating the effects of an intervention among diabetic women (40 years or older) who belong to the Basic Health Units System (Brazilian public health system). The novelty of this project is that the intervention is low cost and demands very little from the health system in terms of structure, facilities and personnel.

Detailed description

The objective of this project is to evaluate the effect of a physical exercise program on the biochemical profile of type 2 diabetic women users of Basic Health Units (BHU) in the urban area of the city of Pelotas (Brazil). This is a randomized clinical trial, where two BHU's of the 14 eligible for the study will be drawn for inclusion in the study. Only those units with more than 100 registered diabetic patients are eligible, they also are not linked to educational institutions and do not present Physical activity projects. Four Basic Health Units (BHU) of the municipality of Pelotas (Brazil) were randomized, two for the intervention group and two for the control group. The intervention group will perform circuit-like physical exercises three times a week and the control will receive counseling to practice physical activity and meetings every 15 days with the womens to carry out walks. The program lasted 12 weeks, with three weekly sessions and presented four distinct sequences containing 10 exercises each, which were performed and circuit form and modified every three weeks. In the first week of the intervention, the women performed a passage in the circuit and with each new week a passage was increased, until the number of three passes was reached (number of passages kept fixed until the end of the intervention). Each exercise initially had a duration of 30 seconds, with a duration of 10 seconds added every three weeks up to a maximum of 60 seconds; The interval of 30 seconds between exercises was kept fixed throughout the intervention. The intensity was controlled by the subjective perception of effort. Mainly blood chemistry will be measured and evaluated.Possible confounding factors to be controlled: age, skin color, schooling, family income, weight, Body Mass Index (BMI), alcohol consumption, smoking, waist circumference, time to diagnose the disease, use of Medicines for diabetes and eating habits. The information will be collected at the baseline, at the eighth week and at the end of the study. Descriptive analyzes of the data will be performed initially, the associations will be tested by correlation, t-test and ANOVA for repeated measures. For comparisons of categorical variables, Chi-square tests will be used for heterogeneity or linear trend. The multivariate analysis will be run through logistic regression. The analyzes will be performed by intention to treat and by adherence, and the level of significance accepted for the study will be 5%. This study will seek to fill gaps in the knowledge about intervention studies in BHU's in order to identify whether physical exercise interventions with proper planning and orientation can promote improvements in the severity of the disease in diabetic women.
