Maternal Occupational Tobacco Exposure and Newborn Umbilical Cord Serum Leptin Concentration.

Objective: To assess the effect of maternal occupational tobacco handling (bidi rolling) on cord serum leptin levels.

Methods: We enrolled 64 neonates born to women who were bidi-rollers, and 64 small for gestational age (SGA) neonates and 57 term appropriate for gestational age (AGA) neonates born to mothers with no tobacco exposure. Cord blood leptin levels between the groups were compared.
