The association between hepatitis and osteoporosis: a nested case-control study using a national sample cohort
- 117 Downloads
The prevalence of hepatitis B was higher in osteoporosis patients than the control group, especially in females. However, the prevalence of hepatitis C was not different. The matching for various factors improved to have same conditions between osteoporosis patients and the control group.
Although chronic liver disease, including hepatitis B and hepatitis C, has been associated with osteoporosis in previous studies, the evidence was insufficient, and some findings were inconsistent. The aim of this study was to evaluate the relationship between hepatitis B or hepatitis C and osteoporosis.
We used the Korean National Health Insurance Service-National Sample Cohort with ≥ 50-year-old participants from 2002 to 2013. Age was determined at osteoporosis diagnosis. We extracted 68,492 osteoporosis patients (ICD-10 codes E7001–E7004, HC341–HC345) with a 68,492-member control group at a ratio of 1:1 by age, sex, income, region of residence, hypertension, diabetes, and dyslipidemia. We analyzed previous histories of hepatitis B (ICD-10 codes B18.0–B18.1) and hepatitis C (ICD-10 code B18.2) in the osteoporosis patients and control groups. The logistic regression with the crude and adjusted model was analyzed. Additionally, subgroup analyses divided by age and sex were performed.
The adjusted odds ratios for hepatitis B and hepatitis C were 1.19 (95% confidence interval (CI) = 1.11–1.28, P < 0.001) and 1.04 (95% CI = 0.90–1.19, P > 0.05), respectively, in osteoporosis patients. Subgroup analyses showed that the risk of hepatitis B was higher in osteoporosis patients in female groups but not in male groups.
Hepatitis B virus infection might be a risk factor for osteoporosis.
