Abstract

Purpose: To evaluate the possible relationship between self-reported history of abortion and nonalcoholic fatty liver disease (NAFLD) in middle-aged and elderly Chinese women.

Methods: A cross-sectional study was performed in 5911 women aged 40 years or older in Jiading District, Shanghai, China. Reproductive histories, including miscarriage and induced abortion, were collected using a validated questionnaire by trained physicians. Abdominal B-mode ultrasound evaluation and serum liver enzymes levels were used in the diagnosis of NAFLD.

Results: The percentage reporting history of abortion in women with NAFLD was higher than in those without NAFLD (72.4% vs. 69.3%, age-adjusted P = .001). Compared with women without a history of abortion, the fully adjusted odds ratio (OR) for NAFLD in those with a history of abortion was increased by 28% (OR, 1.28 and 95% confidence interval [CI], 1.06-1.55). Histories of miscarriage and induced abortion were also associated with increased risk of prevalent NAFLD in fully adjusted models (OR, 1.84 and 95% CI, 1.24-2.72; OR, 1.23 and 95% CI, 1.02-1.50, respectively).

Conclusions: Both miscarriage and induced abortion are associated with prevalent NAFLD in middle-aged and elderly Chinese women.
