Association between pre-pregnancy low-risk factors and risk of obesity in offspring.
PAR, population attributed risk.
Adjusted for mother’s age at birth (years), mom’s race/ethnicity (white, others), parity (null-parity, 1, 2, 3, ≥4 previous pregnancies), pre-pregnancy alcohol intake (0, 0-5, 5-15, ≥15g/day), educational attainment of spouse/partner (high school/college, graduate school), and gender of the offspring (boy, girl). Reference group for relative risk calculation is all other women with no low risk factor.
Table 1 in supplement shows the numeric estimates of relative risk and population attributed risk.
