Odds ratios for independent risk factors associated with being overweight or obese in the final logistic regression model for 9206 5 and 6 year old children in rural Bavaria

	Odds ratio (90% CI) for:
	Being overweight		Being obese
Breast feeding	0.79 (0.68 to 0.93)		0.75 (0.57 to 0.98)
High level of parental education (⩾10 years)*	0.81 (0.70 to 0.95)		0.75 (0.58 to 0.98)
Maternal smoking during pregnancy	1.52 (1.81 to 1.95)		1.85 (1.26 to 2.71)
Birth weight <2500 g	0.68 (0.53 to 0.88)		0.81 (0.54 to 1.20)
Own bedroom	1.24 (1.05 to 1.46)		1.20 (0.91 to 1.59)
Consumes butter ⩾3 times/week	0.72 (0.62 to 0.84)		0.69 (0.54 to 0.90)

^*This variable changed the odds ratio for breast feeding and being overweight or obese by at least 10%, so confounding was assumed to have occurred.
