Assessing Latent Effects of Prenatal Cocaine Exposure on Growth and Risk of Cardiometabolic Disease in Late Adolescence: Design and Methods

Table 2

Self-reported drug use during pregnancy among women giving birth to infants with or without prenatal cocaine exposure in the Miami Prenatal Cocaine Study.

Drug	Mothers of non-cocaine-exposed infants (n = 223)		Mothers of cocaine-exposed infants (n = 253)
	Total drug exposure, median (min to max)*	% Using (n)	Total drug exposure, median (min to max)*	% Using (n)
Alcohol (number of drinks)^†	54 (2 to 1680)	30.9 (69)	96 (1 to 5226)	66.8 (169)
Tobacco (number of cigarettes)^†‡	854 (1 to 5880)	17.0 (38)	2184 (1 to 8820)	73.5 (186)
Marijuana (number of joints)^†	28 (1 to 807)	11.7 (26)	24 (1 to 1320)	45.1 (114)
Cocaine/crack (number of lines/rocks)	⋯	⋯	134 (1 to 19600)	68.4 (173)

*Median values based only on mothers reporting use, calculated using total exposure composites: (number of weeks used) × (usual number of days per week) × (usual dose per day).
^†P < 0.01, between-group comparisons of percentage of maternal drug use (columns 2 and 4).
^‡P < 0.05, between-group comparisons of median maternal drug use (columns 1 and 3).
