This study was performed to determine the relationship between leisure-time physical activity (LTPA) and the metabolic syndrome (MS) in 16,681 adults (43 ± 0.44 y) enrolled in NHANES III.
LTPA was classified as regularly active (≥ 5 d/wk moderate and/or ≥ 3 d/wk vigorous), irregularly active (some LTPA), or inactive (no LTPA). The MS was positive with three or more conditions: 1) abdominal obesity, 2) low HDL-C, 3) hypertriglyceridemia, 4) elevated blood pressure, or 5) elevated glucose. Logistic regression examined the relationship between LTPA and the MS, adjusting for age, race, smoking status, and educational attainment stratified by gender.
In men only, irregular activity and inactivity was related to an increase in the MS (irregular: OR = 1.52 95% CI 1.11, 1.23; inactive: OR = 1.60, 95% CI 1.18, 1.98; test for trend P = 0.004). Inactivity increased the odds for abdominal obesity (P < 0.05).
LTPA levels might influence the development of MS and abdominal obesity.
