A longer duration of lactation (> 6 months) is associated with lower odds of non-alcoholic fatty liver disease (NAFLD) in mid-life women and may represent a modifiable risk factor for NAFLD, a recent study found. Participants from the Coronary Artery Risk Development in Young Adults cohort study who delivered ≥1 child post-baseline and underwent CT quantification of hepatic steatosis 25 years following cohort entry were included. Among the findings:
- Of 844 women who delivered after baseline, 32% reported lactation duration 0 to 1 month, 25% reported >1 to 6 months, 43% reported >6 months, while 54 (6% had NAFLD.
- Lactation duration >6 months was protective against NAFLD in mid-life after adjustment for confounders.
- The benefits of increased lactation duration on weight and waist circumference mediated < one-fourth of this benefit.
