Abstract
INTRODUCTION:
Physical activity is a well-established lifestyle intervention used to decrease weight and the risk of developing chronic medical conditions such as Type 2 Diabetes and Cardiovascular Disease. In an increasingly sedentary society, there is a need to discover new approaches to encouraging exercise in individuals at risk. This pilot study evaluated the effectiveness of a culturally sensitive exercise intervention in obese African American women with prediabetes.
METHODS:
A prospective cohort of 64 participants aged 18 to 70 not taking weight-loss medication was recruited into a tiered, supervised physical activity intervention. Of the 64 enrolled, 28 individuals completed the study. The intervention consisted of various exercises, increasing in intensity every phase, taught by faculty at Norfolk State University over the course of 24 weeks. Following the intervention, participants were encouraged to continue exercising independently for the remaining 24 weeks of the study. Participants were evaluated at the Strelitz Diabetes Center every 12 weeks for a series of clinical tests, with laboratory tests being obtained every other visit. The primary outcome was weight loss and its maintenance at Weeks 24 and 48. Additionally, descriptive statistics of the changes in blood pressure, heart rate, weight, BMI, body fat percentage, and laboratory values throughout the study were calculated using data from the Baseline, Week 24, and Week 48 visits.
RESULTS:
Throughout the course of the study, participant vitals improved. From the initial visit to Week 48, participants lost an average of 4.93±1.6 pounds. Interestingly, from Week 24 to Week 48 there was an average weight gain of 0.96±1.2 pounds. Additionally, among the laboratory tests conducted, there was an average increase in the fasting blood glucose and total cholesterol by 1.61±1.8 mmol/L and 0.14±4.2 mg/dL respectively. Further analysis revealed that these values were decreased in the supervised half of the study and increased during the unsupervised phase.
CONCLUSION:
Overall, the exercise intervention led to modest improvements in vitals and laboratory values in high-risk individuals during the supervised phase. These findings warrant further investigation to improve long-term adherence in prediabetic and diabetic populations.
