RESUMO
PURPOSE: This study examines the relationship between perinatal substance use and adverse pregnancy outcomes among a select group of high risk women residing in the state of Hawaii. METHODS: Participants were the 2,750 women who had live births during 1994 and 1995 and were enrolled in Hawaii's Perinatal Support Services (PSS) program. Demographic and behavioral risk factors associated with selection for participation in the PSS program were examined along with patterns of substance use and adverse perinatal outcomes. PRINCIPAL FINDINGS: After adjustment for demographic factors, Hawaiian/part Hawaiian women compared to non-Hawaiian women were 1.5 times as likely to drink alcohol (p<0.01) and 1.8 times as likely to smoke (p<0.001). Among these women, the relative risk (RR) for preterm delivery was significantly higher for those who used alcohol (RR=1.7, p=0.027), tobacco (RR=1.6, p=0.027), or illicit drugs (RR=1.8, 0.029). Among the same women, the relative risk for low birth weight was significantly higher for those who smoked (RR=1.6, p=0.010) or used illicit drugs (RR=1.7, p=0.046). CONCLUSION: Hawaiian/part Hawaiian PSS women had a higher prevalence of substance use than non-Hawaiian PSS women, even after adjusting for age, education, and marital status. RELEVANCE TO ASIAN AMERICAN AND PACIFIC ISLANDER POPULATIONS: Special attention must be paid to the reasons why Hawaiian/part Hawaiian pregnant women use tobacco and alcohol at higher rates than women of other ethnic groups enrolled in Hawaii's PSS Program. Furthermore, services to assist pregnant women refraining from using illicit drugs should be supported.
