This study aimed to identify intrapersonal, behavioral, and environmental factors associated with engaging in recommended levels of physical activity among rural Latino middle school youth. Data were from an anonymous survey of 773 Latino youth (51% female) about level of and barriers and motivators to physical activity, risk behaviors, and park use. Logistic regression models identified factors correlated with meeting recommended levels of physical activity (5 days or more 360 min/day). Thirty-four percent of girls and 41% of boys reported meeting this physical activity recommendation. Participation in an organized after school activity (p < .001) and in physical education (PE) classes 5 days a week (p < .001) were strongly associated with meeting recommended physical activity level. Making PE available 5 days a week and creating opportunities for organized after school physical activity programs may increase the number of rural Latino middle school youth who meet recommended physical activity level.

Background:

The goals of this study were to examine 1) longitudinal trajectories of energy expenditure from recreational physical activity (PA) in postmenopausal women, 2) whether women who belong to different PA trajectories engage in different types of PA, and 3) whether baseline sociodemographic, health, psychosocial, and lifestyle characteristics predict membership in PA trajectories.

Methods:

Women from the Women’s Health Initiative Observational Study with baseline PA data (n = 92,629) were included. Physical activity, measured via self-report 6 times over 8 years, was converted to MET hr/wk for analysis. Latent growth curve mixture models and latent profile models were used to analyze longitudinal PA trajectories and cross-sectional PA composition, respectively.

Results:

Three distinct, stable PA trajectories (highly, moderately, and minimally active) were identified with nearly 75% of the women classified as minimally active (≤ 8 MET-hr/wk). The majority of women who were at least moderately active engaged in a balanced combination of walking, moderate, and vigorous PA. Sociodemographic characteristics such as income, education, and past vigorous PA were predictive of PA trajectory, as were some health status indicators (eg, body mass index), but not health related quality of life.

Conclusions:

Self-reported PA is largely stable across nearly a decade of follow-up in postmenopausal women.

Background:

Recent research demonstrates the importance of targeting the built environment to support individual physical activity, particularly for people experiencing health disparities. Master plans to promote biking and/or pedestrians (BPMPs) are a potential method for environmental change. This descriptive study aims to provide a snapshot of plan attributes and better understand demographic, social and transportation characteristics of communities with BPMPs.

Methods:

We collected a census sample of BPMPs from 4 states. Population and commuting data were obtained from national statistics.

Results:

294 master plans were included, with most plans representing municipalities. 62% of plans targeted biking only, one-fifth targeted biking and walking, and 15% targeted walking only. The sampled locations have a similar demographic profile as the overall U.S. for median age and household income, people of color, high school education, and income inequality. The degree of racial diversity of sampled communities is slightly less than the U.S. average and the percentage of people who walk to work were slightly higher.

Conclusions:

Given that communities with master plans have a similar profile as the overall U.S., BPMPs could feasibly be spread to communities throughout the country. Further research is planned to describe BPMPs in detail toward informing future plan development.
