The condition of neighborhood parks following Hurricane Katrina: development of a Post-Hurricane Assessment instrument.

Background: Parks provide environments for physical activity, yet little is known about how natural disasters affect them or how these disasters alter physical activity. Our objectives were to (1) describe the development of an instrument to assess park conditions following a hurricane and (2) document the conditions of New Orleans' parks 3 and 6 months after Hurricane Katrina.

Methods: A Post-Hurricane Assessment (PHA) instrument was developed and implemented in 54 parks 3 and 6 months post-hurricane.

Commercial venues as supports for physical activity in adolescent girls.

Objective: The purposes of this study were to describe the types and availability of commercial facilities for physical activity (PA) in six diverse geographic areas (Washington DC and Maryland; South Carolina; Minnesota; Louisiana; Arizona; and California) and to assess the relationship between those facilities and the non-school PA of adolescent girls.

Methods: A total of 1556 6th grade girls participating in the Trial of Activity for Adolescent Girls (TAAG) wore accelerometers for 7 days providing 6 days of complete data, completed questionnaires in 2003 and had their residential addresses geocoded. Nearby commercial facilities available to provide PA (i.

Girls' perception of physical environmental factors and transportation: reliability and association with physical activity and active transport to school.

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.

Development of a Direct Observation Instrument to Measure Environmental Characteristics of Parks for Physical Activity.

Background: The study's purpose is to describe the development and evaluate the reliability (inter-observer agreement) and validity (rater agreement with a gold standard) of a direct observation instrument to assess park characteristics that may be related to physical activity.

Methods: A direct observation instrument of 181 items was developed based on a conceptual model consisting of the following domains: features, condition, access, esthetics, and safety. Fifteen pairs of observers were trained and sent to two parks simultaneously to assess two Target Areas each.

Physical activity attitudes, preferences, and practices in African American, Hispanic, and Caucasian girls.

Physical activity levels in girls decline dramatically during adolescence, most profoundly among minorities. To explore ethnic and racial variation in attitudes toward physical activity, semistructured interviews (n = 80) and physical activity checklists (n = 130) are conducted with African American, Hispanic, and Caucasian middle school girls in six locations across the United States. Girls from all groups have similar perceptions of the benefits of physical activity, with staying in shape as the most important.

Reproductive decision-making among HIV-Infected women.

Objective: To describe factors related to reproductive decision-making among HIV-infected women.

Materials And Methods: A sample of HIV-infected women (N=104) who received care at an HIV clinic in the southern United States were interviewed about their reproductive decision-making. Women who became pregnant subsequent to HIV diagnosis were compared to women who did not become pregnant, and women who underwent a sterilization procedure subsequent to HIV diagnosis were compared to women who did not get sterilized.

Self-management strategies mediate self-efficacy and physical activity.

Background: Self-efficacy theory proposes that girls who have confidence in their capability to be physically active will perceive fewer barriers to physical activity or be less influenced by them, be more likely to pursue perceived benefits of being physically active, and be more likely to enjoy physical activity. Self-efficacy is theorized also to influence physical activity through self-management strategies (e.g.

The obesity epidemic: incidence and prevalence.

Obesity is a major public health problem in the United States and in Louisiana in particular. The prevalence of both overweight and obesity has increased in the past two decades. National studies and studies conducted in Louisiana in adults and children have shown that overweight and obesity are related to conditions such as hypertension, diabetes, stroke, and insulin resistance syndrome.

The significance of parks to physical activity and public health: a conceptual model.

Park-based physical activity is a promising means to satisfy current physical activity requirements. However, there is little research concerning what park environmental and policy characteristics might enhance physical activity levels. This study proposes a conceptual model to guide thinking and suggest hypotheses.
