A comparison of breastfed children with nutritional rickets who present during and after the first year of life.
This study compares the patient characteristics of breastfed children in Baltimore, Maryland from 1990 to 2000 diagnosed with nutritional rickets at 12 months or younger to those older than 12 months to gain a better understanding of nutritional and environmental factors. All 30 of the patients were African American. Patients 12 months or younger (n=15) compared to those older than 12 months (n=15) were more likely to be born during the summer and to present with seizures and hypocalcemia. We recommend vitamin D supplementation of all breastfed infants at an early age and that supplementation continue throughout the duration of breastfeeding.
