Light-Intensity Physical Activity and Cardiometabolic Risk Among Older Adults With Multiple Chronic Conditions:

Purpose:To assess the relationship between light-intensity physical activity (LIPA) and cardiometabolic risk factors among middle-aged and older adults with multiple chronic conditions.Design:Cross-sectional design utilizing data from the Health and Retirement Study (2010, 2012).Setting:Laboratory- and survey-based testing of a nationally representative sample of community-dwelling middle aged and older adults.Participants:Adults aged 50 years and older (N = 14 996).Measures:Weighted metabolic equivalent of tasks was calculated using self-reported frequency of light, moderate, and vigorous physical activity. Cardiometabolic risk factors (systolic and diastolic blood pressure, glycosylated hemoglobin [HbA1c], high-density lipoprotein cholesterol [HDL-C], total cholesterol, and non-HDL-C) were objectively measured. A multiple chronic condition index was based on 8 self-reported chronic conditions.Analysis:Weighted multivariate linear regression models.Results:Light-intensity physical activity was independen...
