Key result
High physical activity compared to inactivity was associated with a lower prevalence of ischemic heart disease among normal-weight adults aged ≥45 years (OR 0.49; 95% CI 0.42-0.57).
Why the study?
Does higher physical activity level reduce the prevalence of ischemic heart disease in adults aged 45 years and older with normal weight?
Cross-Sectional (n=94,455)
Does higher physical activity level reduce the prevalence of ischemic heart disease in adults aged 45 years and older with normal weight?
Even among normal-weight adults aged 45 and older, higher levels of physical activity are independently associated with a significantly lower prevalence of ischemic heart disease.

Supports promoting physical activity in normal-weight adults ≥45 years; hypothesis-generating and requires prospective confirmation.
BACKGROUND: Most ischemic heart disease (IHD) prevention programs that promote physical activity (PA) have focused on overweight/obese populations. Persons with normal body mass index (BMI) may mistakenly think that they are not at risk for IHD and remain physically inactive. Studies exploring the risk of IHD and PA level among adults aged 45 years and older with normal weight are limited. METHODS: Cross-sectional study to examine the prevalence of IHD and PA level among 94455 respondents aged 45 years and older with normal BMI using the 2007 Behavioral Risk Factor Surveillance System data. RESULTS: Approximately 50% of respondents reported low/inactive PA. The prevalence of IHD among persons with inactive, low, medium, and high PA was 16.6% (95% CI=15.1-18.1%), 9.6% (8.9-10.3%), 8.9% (8.3-9.6%), and 5.4% (4.9-5.9%). The adjusted odds ratios of IHD among persons with low, medium, and high PA compared with those with inactive PA was 0.68 (95% CI=0.59-0.79), 0.63 (0.54-0.73), and 0.49 (0.42-0.57). CONCLUSIONS: The percentage of respondents with low or inactive PA among populations aged 45 years and older with BMI 18 to <25 was alarmingly high and independently associated with higher IHD prevalence. Persons who are not overweight/obese still need to have adequate PA to reduce the risk of IHD.

Wen et al. (2011) conducted a cross-sectional in Ischemic heart disease (n=94,455). High physical activity vs. Inactive physical activity was evaluated on Ischemic heart disease prevalence (OR 0.49, 95% CI 0.42-0.57). High physical activity compared to inactivity was associated with a lower prevalence of ischemic heart disease among normal-weight adults aged ≥45 years (OR 0.49; 95% CI 0.42-0.57).
