Prevalence of Hypocalcemia in Seizures in Infancy

A one-year prospective study on developmentally normal children between 1-mo to 2-y with seizures was done to study the prevalence of hypocalcemia. The contribution of hypovitaminosis-D to hypocalcemia was also studied. Of 78 infants (51 boys) enrolled, 18 (23.1%) had hypocalcemia. Fifteen (19.2%) had hypocalcemia secondary to hypovitaminosis-D and 3 (3.8%) had hypomagnesemia. In infants aged less than 6 mo who were exclusively breastfed, 15 (41.67%) had hypocalcemia in comparison to other two age groups 2 (10.53%) in 6–12 mo age-group and 1 (4.35%) in 1–2 y age-group]. This association was statistically significant (p?=?0.001).
