BACKGROUND AND PURPOSE: A recent international expert consensus opinion suggested that metabolic dysfunction-associated fatty liver disease (MAFLD) replaces nonalcoholic fatty liver disease (NAFLD), since MAFLD is a better predictor of cardiovascular disease. We estimated the prevalence of FLD in fertile females and evaluated the clinical impact of either NAFLD or MAFLD on maternal and fetal outcomes during subsequent pregnancy.
METHODS: The study population included fertile females who underwent health examinations and became pregnant within 1 year of health examination. Hepatic steatosis was defined as a fatty liver index of ≥ 30. The fertile females were divided into four groups: neither-FLD, NAFLD-only, MAFLD-only, and both-FLDs. During subsequent pregnancy, the risks of adverse pregnancy outcomes, including gestational diabetes, pregnancy-associated hypertension, preterm birth, and low birthweight, were compared among the four groups.
RESULTS: The study population comprised 762,401 females, including 720,606 with neither-FLD, 318 with NAFLD-only, 14,371 with MAFLD-only, and 27,106 with both-FLDs. Compared to females with neither-FLD, the risk of adverse pregnancy outcomes was higher in females with any FLD, with an adjusted OR of 1.73 (95% CI 1.25-2.41) in the NALFD-only group, 2.65 (2.53-2.77) in the MAFLD-only group, and 2.39 (2.31-2.48) in the both-FLDs group. Pregnancy outcomes (cesarean delivery, gestational diabetes, and low birthweight) were worse in females with MAFLD compared with NAFLD.
CONCLUSION: Any form of FLD is a risk factor for adverse pregnancy outcomes. These data suggest that MAFLD is associated with a higher risk of adverse pregnancy outcomes for both mother and fetus than NAFLD.
