Poor physical activity in the elderly as assessed by a visual analogue scale is associated with dyslipidemia

The aim of the present study was to evaluate the association between a subjective measure of physical activity assessed by a Visual Analogue Scale (VAS) and dyslipidemia in an elderly population of Iran. A total of 74 elderly subjects (39 males) aged 65 years and older who referred to the Cardiovascular Department of the Hospital were studied. Physical activity was assessed on a 100 mm VAS according to which patients were then divided in to two groups active (activity score > or = 50; n = 31) and inactive (activity score < 50; n = 43). Body Mass Index (BMI), systolic and diastolic blood pressure, triglycerides, total cholesterol, Low-Density Lipoproteins (LDL) and High-Density Lipoproteins (HDL) were measured by standard methods. TG (p = 0.021) and LDL (p = 0.006) were significantly higher and HDL was significantly lower (p = 0.028) in the inactive group. No significant associations were found for other variables. As the first report from Iran, present results are important given the race differences that exist in response of plasma lipids to exercise training. Limitations of the present study include its cross-sectional, rather than prospective, structure and the relatively small sample size. It remains to be seen whether VAS can be used as a rapid screening tool for the presence of dyslipidemia in the elderly.
