PA was evaluated by means of a questionnaire aimed to assess intense and sedentary activities on the previous day. This information was then converted to metabolic equivalents (METs). Serum CRP concentrations were determined by a high‐sensitivity assay. CRP values >10mg/L were eliminated. Information on sociodemographic characteristics, diet (24‐hr dietary recall), supplements, habits, chronic disease (self‐reported diabetes, hypertension and coronary heart disease), and anthropometry (weight and height) was also obtained. A total of 706 non‐pregnant women 12 to 49 y (mean 30.0 ± 9.3 y) were evaluated. Mean PA was 49.0 ± 8.34 METs/day. Median CRP was 1.7 mg/L (interquartile range: 0.74, 3.9). Prevalence of elevated CRP concentrations (≥3 to 10 mg/L), was 32%. An inverse association was observed between PA and CRP (p<0.05). After adjusting by age, BMI, energy and alcohol intake, tobacco use, vitamin supplements, chronic disease, socioeconomic status, and ethnicity, logistic regression analysis showed that women in the lowest quartile of PA had greater risk of elevated CRP, compared to women in the highest quartile (OR: 2.32, 95% CI: 1.17, 4.64). Age, BMI, tobacco use, and chronic disease were positively associated with elevated CRP (p<0.05). It was concluded that PA is negatively associated with low‐intensity chronic inflammation in Mexican women of reproductive age.
