Background  The relationship between light intensity physical activity ( PA ), which is common in older adults, and cardiovascular disease ( CVD ) risk factors is unclear. This study examined associations of accelerometer‐measured  PA  intensity with  CVD  risk factors in older women of different race‐ethnicities.    Methods and Results  Cross‐sectional analyses were conducted in 4832 women (mean age 78.9 years; 52.5% white, 30.5% black, 17.1% Hispanic) who were without known  CVD  and wore triaxial accelerometers a minimum of 4 of 7 days with ≥10 hours/d awake wear‐time. Vector magnitude counts per 15‐s epoch were used to define time spent in low light (19–225 counts/15 s), high light (226–518), and moderate‐to‐vigorous; ≥519) intensity  PA . Fasting  CVD  biomarkers, resting blood pressure, waist girth, body mass index, and 10‐year predicted  CVD  risk (Reynolds Risk Score) were measured. After adjusting for age, wear time, race‐ethnicity, and potential confounders, each  PA  measure was favorably associated with mean high‐density lipoprotein, triglyceride, glucose, C‐reactive protein, body mass index, waist girth, and Reynolds Risk Score ( P <0.05, all). Associations with mean blood pressure, insulin, and total and low‐density lipoprotein cholesterol were variable. A 30‐minute/d increment in  PA  was associated, on average, with odds ratios for high predicted  CVD  risk (Reynolds Risk Score ≥20) of 0.96 (95% confidence interval, 0.92, 1.00), 0.88 (0.83, 0.94), and 0.85 (0.79, 0.91) for low light, high light, and moderate‐to‐vigorous, respectively, and remained significant with further mutual control for  PA  intensity.    Conclusions   PA  measured by accelerometry, including light intensity  PA , was associated with lower  CVD  risk factor levels in race‐ethnically diverse older women.
