The objective of this study was to describe associations between childhood
factors and adult daily substance use profiles among homeless women and to
identify independent predictors of daily substance use for the overall samp
le and for ethnic/acculturation subgroups. Structured surveys were administ
ered to 1,331 homeless women in Los Angeles who were either daily drug and
alcohol users for the past 6 months or nondaily substance users. Physical a
buse and parental drug abuse predicted daily drug use in the whole sample a
nd selected subgroups, whereas parental alcohol abuse predicted daily alcoh
ol use in the whole sample. Teen self-esteem was also found to have a prote
ctive effect an daily alcohol use for the sample and for African American w
omen. Negative peer influence in adolescence predicted daily drug use among
high-acculturated Latinas. In summary, childhood abuse, parental substance
use, and negative peer influence affect important roles in homeless women'
s daily substance use.
