Factors Associated With the Risk Discontinuing 'Any Breastfeeding' to Six Months, Xinjiang, PR China, 2003–2004

Factors	Values	Cox Regression
		n	HR	95% CI
Ethnics	Han	40	1
	Uygur	164	2.93	1.14	7.56
	Others	63	0.94	0.31	2.88
Age of Infant When Mother Returned to Work	No Job	77	1
	>= 6 Months	143	1.69	0.80	3.59
	< 6 Months	47	3.57	1.61	7.89

2 log likelihood (deviance) = 630.94, df = 4.

Non-significant variables were birth seasons, maternal age, job, years of education, delivery method, whether demand fed, time of making decision about infant feeding method, the time of baby's first suckling after birth, baby's first feed, how early breastmilk 'came in', whether maternal mother breastfed her babies, maternal mother's feeding preference, baby's gender, the gender mother prefer, baby's birthweight, mother's knowledge of formula, number of family members, whether pacifier used, whether mother able to breastfeed after returning to work.

All variables in the final model were variables for which, when excluded, the change in deviance compared with the corresponding chi-square test statistic on the relevant degrees of freedom was significant.

HR is Hazard Ratio and 95% CI is 95% confidence intervals.
