Influences on neighborhood walking in older adults.

The purpose of this cross-sectional survey study was to examine the influence of self-efficacy, outcome expectations, and environment on neighborhood walking in older adults with (n = 163, mean age = 78.7, SD = 7.96 years) and without (n = 163, mean age = 73.6, SD = 7.93 years) mobility limitations, controlling for demographic characteristics. Multiple regression revealed that in mobility-limited older adults, demographic characteristics, self-efficacy, and outcome expectations explained 17.4% of variance in neighborhood walking, while environment (neighborhood destinations and design) explained 9.4%. Destinations, self-efficacy, sex, and outcome expectations influenced walking. In those without mobility limitations, demographic characteristics, self-efficacy, and outcome expectations explained 15.6% of the variance, while environment explained 5.6%. Self-efficacy, sex, and design influenced walking. Neighborhood walking interventions for older adults should include self-efficacy strategies tailored to mobility status and neighborhood characteristics.

A parent-adolescent intervention to increase sexual risk communication: results of a randomized controlled trial.

This article reports results of a randomized controlled trial designed to test an intervention to increase parent-adolescent sexual risk communication among Mexican parents. Data were analyzed from parents (n = 791) randomly assigned to an HIV risk reduction or health promotion intervention. Measures were administered at pretest, posttest, and 6- and 12-month follow-ups. Generalized estimation equation (GEE) analysis indicates parents in the HIV risk reduction intervention reported significantly more general communication (p < .005), more sexual risk communication (p < .001) and more comfort with communication (p < .001) than parents in the control intervention. Behavioral, normative, and control beliefs significantly mediated the effect of the intervention on all communication outcomes. This study demonstrates the efficacy of an intervention to increase the quality and quantity of parent-adolescent communication related to general and sex-specific communication.
