Obesity and childhood obesity are growing public health problems. Some studies have shown a link between early breastfeeding cessation and introduction of complementary foods may be a contributing factor to this problem.

The aims of this study were to determine any relation between breastfeeding and infant BMI, formula consumption and infant BMI, timing of complementary foods and infant BMI, and maternal vitamin D status and infant BMI.

One hundred thirty-two mother-infant pairs were seen at approximately 3, 6, and 9 months post-partum. Anthropometric measurements were taken at all time points. Mother gave 24-hour recall and infant weights before and after feeding at the three month visit, dietary questionnaires were filled out at 6 and 9 months visits. Blood samples were taken from mothers at 3 month visit to analyze for vitamin D status.

No significant relations were found between breastfeeding, formula consumption, timing of complementary foods or maternal vitamin D status and infant BMI.

Our results are supported by what was found in the current literature.
