Abstract
Introduction: We investigated the association between physical activity (PA) and CRP and WBC count in men and women at different age.
Methods: The Moli-sani Project is an ongoing cohort study on subjects aged >=35 yrs, randomly recruited from the general population of a Southern Italian region. After exclusion of subjects with CVD (5%) and incomplete questionnaires (13%), 3,485 females and 3,071 males were cross-sectionally analyzed. PA was assessed by a structured questionnaire (24 questions on working and leisure time). Weekly energy expenditure in metabolic equivalent task-hours (MET-h) and age were were calculated in tertiles. CRP levels were measured by immunoturbidimetric method (IL, Milan, Italy).
Results: Correlation analysis (Pearson's test) showed inverse correlation between CRP and PA (p<0.0001), both in men and women. WBC count was inversely correlated with PA in men (p=0.016), but not in women (p=0.07). High PA was also associated with lower BMI, waist circumference, systolic and diastolic blood pressure, LDL, total cholesterol and triglycerides and higher HDL (p<0.001).
In multivariate regression analysis, CRP was still associated with PA in the younger (p=0.0154) and older (p=0.006) age tertiles in men and in the old age tertile (p=0.023) in women. WBC count remained positively associated with PA in the younger (p=0.018) and older (p=0.006) age group.
Conclusions: PA was associated with a better anti-inflammatory profile both in men and women and was dependent on age.
