Gender differences in the effect of linguistic acculturation on substance use among Mexican-origin youth in the southwest United States.

This study tested for gender differences in the impact of linguistic acculturation on pro-drug norms, substance use intentions, and actual substance use among youth of Mexican heritage in a large metropolitan area in the Southwest United States. The authors analyzed baseline survey data provided by 2,487 middle school students of Mexican heritage who were part of a larger, multiethnic randomized efficacy trial of a drug abuse prevention program. Using multi-group structural equation modeling, the authors found that linguistic acculturation was positively and directly related to adherence to pro-drug norms, substance use intentions, and recent alcohol use, controlling for age, poor grades, and socioeconomic status.

Reducing low birth weight infancy: assessing the effectiveness of the Health Start program in Arizona.

This study compares the incidence of low birth weight among mothers enrolled in Arizona's Health Start program to a sample of non-Health Start mothers with similar medical and social risk factors. A quasi-experimental design was used to match Health Start program participants to non-participants on the basis of similar medical and social risk factors. Health Start program data were linked to birth certificate data to create a sample of 5,480 pregnant women.
