Effect of maternal cigarette smoking on Apgar scores
S. M. Garn, M. Johnston, S. A. Ridella and A. S. Petzold
As shown in a total of 43,492 live-born singleton infants, the proportion
of low and depressed Apgar scores is related to the extent of maternal
cigarette usage during pregnancy. In particular, the three-pack level of
smoking (41 to 60 cigarettes per day) is reflected in a near-quadrupling of
low and depressed one-minute and five-minute Apgar scores in both blacks
and whites and also after exclusion of prematurely born infants.
