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.

This study is an examination of eating behaviors and body image concerns among 587 female collegiate athletes from nine colleges/universities representing 14 different sports. Measures included the Eating Disorders Inventory-2 (EDI-2), the Eating Attitudes Test (EAT-26), and a questionnaire gathering general demographic information, reasons for dieting and/or using other methods of weight control, as well as information about expressed concerns from others regarding the respondents weight. Three sport groups were hypothesized to be at increased risk: athletes whose performance is subjectively scored; athletes who compete in a sport where a low body weight is considered advantageous; and athletes who must wear body conrevealing clothing. Chi-Square and Logistic Regression analyses revealed no association between these sport groups and the presence of a subclinical eating disorder (SED). Additional analyses determined no statistical association between student-athletes competing at the National Collegiate Athletic Association Division I level (versus Division II or III level) or student-athletes who were scholarship recipients (versus non-scholarship recipients) and the presence of SED. Student-athletes who have heard expressed concerns from others regarding their body weight were significantly more likely to report the presence of SED (p < .0001). Therefore, special care should be taken with all student-athletes when discussing body weight.
