Public Health Perspectives on the Family: An Ecological Approach to Promoting Health in the Family and Community

The family, as a setting of practice, is increasingly recognized as critical to health promotion. A better understanding of the nature and process through which families take an active part in their own health can serve as the basis for designing and linking health interventions with public health programs. The integrating function of the family, viewed through an ecological context, makes it an effective entry point and central focus in health promotion.

Using the rural-urban continuum to explore adolescent alcohol, tobacco, and other drug use in Montana.

The purpose of the study was to compare 30–day prevalence of alcohol, tobacco, and other drug use among twelfth-grade students in Montana across a rural-urban continuum during 2000, 2002, and 2004. The methods include an analysis of the Montana Prevention Needs Assessment (N = 15,372) using multivariable logistic regression adjusting for risk factors, protective factors, and demographics variables. Findings revealed that adolescent substance use varies across the rural-urban continuum. Risk of cigarette, smokeless tobacco, and alcohol use increased in more rural counties while risk of marijuana, LSD, and any drug decreased in more rural counties. The specificity provided through use of such a classification scheme has important implications for designing effective drug-prevention programs across diverse settings.

Growth in Adolescent Self-Regulation and Impact on Sexual Risk-Taking: A Curve-of-Factors Analysis

Adolescent self-regulation is increasingly seen as an important predictor of sexual risk-taking behaviors, but little is understood about how changes in self-regulation affect later sexual risk-taking. Family financial stress may affect the development of self-regulation and later engagement in sexual risk-taking. We examined whether family financial stress influences self-regulation in early adolescence (age 13) and growth in self-regulation throughout adolescence (from age 13–17 years). We then assessed the effects of family financial stress, baseline self-regulation, and the development of self-regulation on adolescent sexual risk-taking behaviors at age 18 years. Using a curve-of-factors model, we examined these relationships in a 6-year longitudinal study of 470 adolescents (52% female) and their parents from a large northwestern city in the United States. Results indicated that family financial stress was negatively associated with baseline self-regulation but not with growth in self-regulation throughout adolescence. Both baseline self-regulation and growth in self-regulation were predictive of decreased likelihood of engaging in sexual risk-taking. Family financial stress was not predictive of later sexual risk-taking. Intervening to support the development of self-regulation in adolescence may be especially protective against later sexual risk-taking.
