Department of Public Health Scholarship and Creative Works

Background

Preliminary evidence suggests that the physical environment and transportation are associated with youth physical activity levels. Only a few studies have examined the association of physical environmental factors on walking and bicycling to school. Therefore, the purpose of this study was (1) to examine the test-retest reliability of a survey designed for youth to assess perceptions of physical environmental factors (e.g. safety, aesthetics, facilities near the home) and transportation, and (2) to describe the associations of these perceptions with both physical activity and active transport to school.

Methods

Test and retest surveys, administered a median of 12 days later, …

Early Predictors Of Sexual Behavior: Implications For Young Adolescents And Their Parents, Lisa D. Lieberman

Department of Public Health Scholarship and Creative Works

The study provides empirical evidence of the independent contribution of nonsexual romantic relationships in the seventh grade to the onset of sexual intercourse by the ninth grade for both males and females. In addition, it shows that among females, seventh graders in serious relationships with older teenagers—uniquely defined as those two or more years older—have an increased likelihood of sex in the ninth grade. Finally, the study demonstrates that seventh graders of both genders who have had serious romantic relationships were already significantly different in the sixth grade from those who have not: They had peers who were more accepting …

Perceived Smoking Environment And Smoking Initiation Among Multi-Ethnic Urban Girls, Tracy R. Nichols, Amanda Birnbaum, Sara Birnel, Gilbert J. Botvin

Department of Public Health Scholarship and Creative Works

Purpose

To examine associations between the perceived smoking environment and smoking initiation among urban multi-ethnic adolescent girls in New York City.

Methods

Self-report surveys completed in grades 7, 8, and 9 assessed girls’ (n = 858) smoking initiation, and perceived smoking environment (family smoking, friends’ smoking, smoking norms, and cigarette availability). Carbon monoxide breath samples were collected from girls using a variation of the bogus pipeline procedure.

Results

Differences were found in smoking prevalence with white girls reporting the highest prevalence of smoking at baseline and the greatest increase in smoking prevalence from seventh to eighth grade. Black girls reported …

In this longitudinal study, we examined the relationship between changes in time spent watching television and playing video games with frequency of leisure-time physical activity across a 2-year period among adolescent boys and girls (N=4594" role="presentation" style="box-sizing: border-box; margin: 0px; padding: 0px; display: inline-block; line-height: normal; font-size: 16.200000762939453px; word-spacing: normal; word-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; position: relative;">). Latent growth modelling indicated that a decrease in time spent watching television was associated with an increase in frequency of leisure-time physical activity. That relationship was strong in magnitude …
