New data from a study featuring more than 55,000 Finnish men and women suggested that moderate and high levels of occupational or leisure-time physical activity may reduce the risk for HF.
The study cohorts included 28,334 men and 29,874 women from Finland, who were free of HF at baseline and between the ages of 25 and 74 years. Researchers utilized baseline measurement of different types of physical activity to predict incident HF and followed patients for a mean of 18.4 years.
During follow-up, HF developed in 1,868 (6.6%) men and 1,640 (5.5%) women. After adjusting for multivariates, including age, smoking, BMI and systolic BP, the HRs for HF were as follows for the three occupational activity levels in men: light, 1.00; moderate, 0.90; and active 0.83 (P=.005 for trend). For women, the HRs for the occupational activity levels were 1.00 for light, 0.80 for moderate and 0.92 for active (P=.007).
Similarly, HRs for HF during leisure time activity also decreased with the progression from low (men, 1.00; women, 1.00) to moderate (men, 0.83; women, 0.84) to high (men, 0.65; women, 0.75) activity levels (P<.001 for both men and women trends).
Study limitations included the self-report of physical activity, and that physical activity was recorded only once at baseline.
“This study confirms that moderate or high levels of occupational or leisure-time physical activity have a negative association with the risk of HF among men and women,� the researchers concluded.
