Using group model building to understand factors that influence childhood obesity in an urban environment.

Background: Despite increased attention, conventional views of obesity are based upon individual behaviors, and children and parents living with obesity are assumed to be the primary problem solvers. Instead of focusing exclusively on individual reduction behaviors for childhood obesity, greater focus should be placed on better understanding existing community systems and their effects on obesity. The Milwaukee Childhood Obesity Prevention Project is a community-based coalition established to develop policy and environmental change strategies to impact childhood obesity in Milwaukee, Wisconsin.

"I am very, very proud of myself": improving youth activity levels using self-determination theory in program development.

Many adolescents are not meeting recommended levels for physical activity. Increasing physical activity among urban African American youth is both a challenge and a public health priority. Most research in community-based interventions has taken a didactic approach, focusing on skill and knowledge development alone, with inconclusive results.

Maintaining physical activity over time: the importance of basic psychological need satisfaction in developing the physically active self.

Purpose: Drawing from self-determination theory, this study investigated adults' perceptions of the process of long-term maintenance of physical activity and how it may relate to their self-identity.

Design: Qualitative study included 22 in-depth interviews and participants' recorded personal reflective journals.

Setting: Health/fitness facility in a Midwestern city.

An investigation of pre-activity cardiovascular screening procedures in health/fitness facilities--part II: rationale for low adherence with national standards.

The purpose of this study was to explore the rationale provided by program directors and general managers of health/fitness facilities for low adherence to nationally accepted standards related to pre-activity cardiovascular screening procedures (PACSPs) for members and clients of personal trainers. Qualitative interviews were conducted with the directors/managers in a Midwest region representing 76 facilities who indicated they did not conduct PACSPs for members and clients of personal trainers. Analysis of the rationale provided revealed 6 major clusters: (1) Purpose or need for screening; (2) time and staffing; (3) barrier to participation; (4) personal responsibility for health and actions; (5) legal issues; and (6) company or franchise policy that categorized the reasons for low adherence to PACSPs.

An investigation of pre-activity cardiovascular screening procedures in health/fitness facilities--part I: is adherence with national standards decreasing?

This investigation determined the number of health/fitness facilities within a Midwestern region conducting pre-activity cardiovascular screening procedures (PACSPs) consistent with American Heart Association/American College of Sports Medicine (AHA/ACSM) standards. Interviews were conducted with 123 commercial, community, corporate, and academic settings (84% response rate), with 40 (33%) facilities requiring members to complete a pre-activity screening device. Of those, 20 (50%) required physician clearance for "at-risk" members prior to physical activity participation.
