Gender differences in college leisure time physical activity: application of the theory of planned behavior and integrated behavioral model.

OBJECTIVE: National data consistently report that males participate in leisure time physical activity (LTPA) at higher rates than females. This study expanded previous research to examine gender differences in LTPA of college students using the theory of planned behavior (TPB) by including 2 additional constructs, descriptive norm and self-efficacy, from the integrated behavioral model. PARTICIPANTS: Participants were college students (N = 621) from a large public university in the southeastern United States. METHODS: A self-report, classroom-based assessment with validated and reliable measures of LTPA, TPB constructs, descriptive norm, self-efficacy, and demographics was conducted in fall 2009. RESULTS: Regression analyses revealed attitude (ß = .119), intention (ß = .438), self-efficacy (ß = .166), body mass index (BMI) (ß = -.084), and sports participation (ß = .081) as significantly associated with LTPA for females (R (2) = .425, p < .001), whereas intention (ß = .371) was significant for males (R (2) = .202, p < .001). CONCLUSIONS: Practitioners should consider tailoring promotional materials to address these gender differences in efforts to increase LTPA participation among college students.

Sleep disturbance and risk behaviors among inner-city African-American adolescents.

Adolescents tend to experience more problems with sleep loss as a natural consequence of puberty, whereas teens from impoverished urban areas are likely to witness neighborhood violence and/or engage in risk behaviors that may affect sleep. Data from the Mobile Youth Survey, a longitudinal study of impoverished inner-city African-American adolescents (1998-2005; N = 20,716; age range = 9.75-19.25 years), were used to compare paired years of annual surveys elicited by questions about how sleep was affected when bad things happen to friends or family. Using a cross-lagged panel multivariate approach comparing reports for two sequential years and controlling for age/gender plus exposure to traumatic stress and violence, prior sleep disturbance was associated with carrying a knife/gun, brandishing a knife/gun, using a knife/gun, quick temperedness, warmth toward mother, worry, and belief in the neighborhood street code in the latter year. Conversely, seeing someone cut, stabbed, or shot, using alcohol, worry, and internalized anger were associated with sleep disturbance in a latter year. Although a limited measure of sleep disturbance was used, these findings support further research to examine sleep disturbance and risk behaviors among low-income adolescents.

The origins of hopelessness among inner-city African-American adolescents.

Much has been written in recent years about hopelessness among residents of impoverished inner-city neighborhoods, but little research has been conducted on the origins of hopelessness. The literature on social disorganization and the literature on child development independently suggest two possible causes of hopelessness among adolescents: disruptive events and lack of connectedness to people and institutions. We explore these two factors as predictors of hopelessness for 5895 youths living in impoverished inner-city neighborhoods in Mobile, Alabama. The longitudinal data for this study allow us to explore the development of hopelessness over time, predicted by prior levels of disruption and connectedness. The results show that over time several variables associated with disruption (Change in Mother Figure, Exposure to Violence, Traumatic Stress, Worry) and connectedness (Sense of Community, Warmth Toward Mother, Religiosity) are positively or negatively associated with increased feelings of hopelessness among inner-city adolescents.
