Table 3. Predictors of infant vitamin D deficiency using multiple logistic regression.

Infant and maternal variables	Odds ratio	p-value	95% confidence interval
Infant age <3 months	5.99	0.004*	1.75–20.54
Darker skin color type (III–VI)	1.71	0.348	0.56–5.28
Sun index	0.78	0.060	0.57–0.98
Maternal VDD	5.96	0.049*	1.004–35.382
Maternal VDI	3.84	0.020*	1.24–11.92

Overall model: LR chi squared=30.83, p=0.0003.

VDD: vitamin D deficiency, VDI: vitamin D insufficiency.
