Pedometer measurement of physical activity and chronic disease risk factors of obese lower socioeconomic status African American women.
2007
Background: To evaluate physical activity with pedometers and health markers of chronic disease in obese, lower socioeconomic African American women. Methods: Thirty-five women (48 ± 8 y) wore pedometers for 2 weeks. One-way analyses of variances were used to compare age, weight, body mass indices (BMI), and health markers of chronic disease (including blood pressure, cholesterol, triglycerides, glycosylated hemoglobin, fibrinogen, C-reactive protein) between women who were classified by steps per day as sedentary (SED < 5,000; 2,941 ± 1,161 steps/d) or active (ACT ≥ 5,000; 7,181 ± 2,398 steps/d). Results: ACT had significantly lower BMI (ACT: 37.2 ± 5.6; SED: 44.4 ± 7.2 kg/m2) and hip circumferences (ACT: 37.2 ± 5.6; SED: 44.4 ± 37.2 cm) and higher total cholesterol (ACT: 230 ± 53; SED: 191 ± 32 mg/dL) than SED. There were no differences in health markers of chronic disease between SED and ACT. Pearson product moment correlations showed significant negative correlations between steps/d and weight (r = –....
