title: Serum levels of C-reactive protein are associated with obesity, weight gain, and hormone replacement therapy in healthy postmenopausal women.
abstract: The authors evaluated the cross-sectional and prospective associations between the serum concentration of C-reactive protein and measures of obesity and fat distribution, hormone replacement therapy (HRT) use, and serum sex hormones in postmenopausal women from the Healthy Women Study (Allegheny County, Pennsylvania, 1998). The authors tested the hypothesis that C-reactive protein levels would be higher among HRT users and among women with greater body mass index, waist circumference, or visceral fat. There were 207 women in the study who were > or =8 years postmenopausal (101 HRT users and 106 HRT nonusers). The median levels of C-reactive protein were 3.01 mg/liter in HRT users compared with 1.74 mg/liter in nonusers (p = 0.002). C-reactive protein levels were strongly positively correlated with measures of body size, fatness, fat distribution, and weight gain among HRT users and nonusers. C-reactive protein was also positively correlated with serum estrone levels (r(s) = 0.38) among HRT nonusers. The highest level of C-reactive protein was found among HRT users in the highest quartile of visceral fat (4.29 mg/liter) compared with women not on HRT and in the lowest quartile of visceral fat (0.96 mg/liter). The use of HRT and measures of overall body fatness are important correlates of C-reactive protein among postmenopausal women.
