- Adj = Adjusted value. No crude values are presented. All values have been corrected for residence (urban vs. rural), ethnicity (Latin vs. non-Latin), work (work vs. no work of the mother), education (≤ 5 years of education vs. >5 years of education) Bf = Breastfeeding Excl = Exclusive, for definition see text. Odds/Hazard ratios with 95% confidence intervals are given for all outcome measures except for "any breastfeeding" where values indicate differences in duration in months. * In all analyses of maternal attitude and feeding pattern, the attitudes "good" (n = 272) and "neutral" (n = 1) were collapsed into one group and then compared with " very good" (n = 229).# Reported attitudes towards breastfeeding have been dichotomized into "positive" vs. "indifferent, negative, the mother reported not knowing the attitude". † Indicates the number of censored/total observations. Hazard ratios > 1 indicate longer exclusive breastfeeding duration (usually hazard ratios in survival analyses indicate an increased risk of "death", i.e. short time to endpoint, but in this case transformations have been carried out to make data easier to interpret for the reader.). π p = 0.0468
