Table 2.

Odds ratios (95% confidence intervals) for the self-perceived health variables in relation to birth weight low versus normal in the upper half and birth weight measured continuously in the lower half of the table. ORs are shown uncorrected and corrected for age, sex, age of mother, parity, and gestational age for the full sample as well as different age and sex sub-samples.
