Association between characteristics of parous women and NAFLD at 25 years: unadjusted and multivariable adjusted odds ratios (95% Cl).

Characteristic	Unadjusted OR (95% CI)	p value	Multivariable^* OR (95% CI)	p value

Age (per 5 year)	1.38 (0.94–2.02)	0.10
White race (vs. Black)	1.29 (0.74–2.25)	0.37	2.36 (1.24–4.50)	0.01
Total post-baseline parity (per birth)^†	0.66 (0.46–0.97)	0.03	0.75 (0.51–1.11)	0.15
BMI (per 3 kg/m² increase)	1.25 (1.10–1.43)	<0.01	1.30 (1.13–1.50)	<0.01
Education >high school vs. ≤high school	0.76 (0.39–1.49)	0.43
Lactation duration (0–1-month reference)
>1 to 6 months	0.91 (0.47–1.78)	0.79	0.84 (0.42–1.70)	0.64

Multivariable model determined by backward stepwise elimination with race, BMI and lactation duration in final model.

^†

Forced into final model to adjust lactation duration for number of post-baseline births.

BMI, body mass index; HOMA-IR, homeostatic model assessment of insulin resistance; NAFLD, non-alcoholic fatty liver disease; OR, odds ratio.
