Although previous research has shown that the NRP instruction improves knowledge and skill among health care personnel in the delivery room, both short-term and long-term, there has been little evidence to demonstrate NRP impact on infant morbidity. Several strategies were used in this study to control for bias and to adjust for secular trends in decreased infant morbidity during the study period. This study demonstrated sufficient support for the hypothesis that a significant improvement occurred among neonates in their Apgar score after the NRP instruction in Illinois. Empirical support is provided for the clinical effectiveness of NRP instruction.

We studied behavioral factors that place intravenous drug users at risk for the acquisition and transmission of the human immunodeficiency virus (HIV) in a sample of 855 individuals not in drug treatment, living in central and southwestern Ohio. The HIV seropositivity rate for the sample was 1.5%. Three factors were significantly related to HIV infection: homeless shelter residence (odds ratio [OR] = 7.7, 95% confidence interval (CI) = 3.0-20.0), travel to northeastern HIV hyperendemic areas (OR = 5.2, 95% CI = 1.8-15.4), and recent male homosexual or bisexual behavior (OR = 11.2, 95% CI = 2.9-43.9).

This study investigated factors influencing child survival to age 5 years for a rural farm sample in Iloilo Province, Philippines. Children from better quality housing were more likely to live to age 5 than were children from worse quality housing. The life expectancy at birth, indirectly estimated by the Brass method, was 63-4 years for children from worse quality housing and 69-9 years for children from better quality housing. The implications are explored.
