    Abstract

    Objective: To evaluate whether five-year changes in self-reported physical activity level were associated with changes in waist circumference, weight, serum lipids and blood pressure. Methods: In the Inter99 study (1999-2006) in Copenhagen, Denmark, 4039 men and women (30-60 years) answered questions on lifestyle and provided blood samples and anthropometric measures at baseline and after five years. Multiple regression analyses were performed with five-year value of each cardiovascular biomarker as outcome and change in physical activity level as explanatory variable. Results: Approximately 50% of the study population were men (n = 2023). Change in physical activity level was inversely associated with change in weight (p < 0.0001), waist (p < 0.0001), diastolic blood pressure (p = 0.04), total cholesterol (p = 0.006), LDL (p = 0.007), triglycerides (p = 0.02) and with a composite risk score "the Copenhagen risk score" (p < 0.0001), and positively associated with HDL in men (p = 0.01). Conclusion: Five-year changes in physical activity level were significantly associated with relevant changes in weight, waist circumference, diastolic BP and serum lipids in a population-based cohort of adult men and women. Change in physical activity level induced a significant change in HDL concentration in men only. Women's use of hormone replacement therapy may partly explain this gender difference.
