Sexual risk classes among youth experiencing homelessness: Relation to childhood adversities, current mental symptoms, substance use, and HIV testing.

The aim of this study was to determine whether there are meaningful subgroups with different types of sexual risk behaviors among youth experiencing homelessness and examine the associations between potential classes and other risk variables. A latent class analysis was used to identify classes of youth according to sexual risk behaviors and sexual assault. A two-class solution was found to be the best fit for the data-Lower and Higher Risk groups.

Association Between Health Beliefs and Gestational Weight Gain.

Background: The Institute of Medicine (IOM) provides recommendations for optimal weight gain during pregnancy to minimize complications associated with obesity and excessive weight gain. The Health Belief Model and prior research suggest knowledge of health recommendations and associated risks motivate health behaviors. This study determined whether knowledge of maternal and infant obesity risks during pregnancy (ORDP) and knowledge of IOM gestational weight gain (GWG) recommendations were associated with total GWG and likelihood of adhering to IOM recommendations.
