The Influence of Home and School Environments on Children's Diet and Physical Activity, and Body Mass Index: A Structural Equation Modelling Approach.

Introduction The home and school environments play important roles in influencing children's health behaviours. However, their simultaneous influence on childhood obesity has not yet been examined. We explore the relationship of the home and school environments with childhood obesity, to determine whether this relationship is mediated by children's fruit and vegetable intake and physical behaviours.

Relationships of sun-protection habit strength with sunscreen use during outdoor sport and physical activity.

The objective of this cross-sectional questionnaire study was to assess associations of a self-report index of sun protection habit strength with sunscreen use in sporting environments and outdoor physical activity. Participants (n = 234) in field hockey, soccer, tennis and surf sports in Queensland, Australia, completed a self-administered survey on sun protection during organized sport, and during general outdoor physical activity during 2005/2006. The sun protection habit strength index was dichotomized into two categories.

Perceived neighborhood environment and park use as mediators of the effect of area socio-economic status on walking behaviors.

Background: Access to local parks can affect walking levels. Neighborhood environment and park use may influence relationships between neighborhood socioeconomic status (SES) and walking.

Methods: Self-report data on perceived park features, neighborhood environment, park use, neighborhood walking and sociodemographics were obtained from a sample of Australian adults, living in high/low SES areas.

Perceived barriers to leisure-time physical activity in adults: an ecological perspective.

Background: Perceived barriers are modifiable correlates of participation in physical activity. Associations of specific perceived barriers with participation in and level of walking for recreation, and other leisure-time physical activity (LTPA) were examined. Personal, social, and environmental factors associated with these perceived barriers were then examined.

Effects of a walking program in the psychiatric in-patient treatment setting: a cohort study.

Issue Addressed: To assess the effectiveness of a walking program in a psychiatric in-patient unit.

Method: In-patients at a private psychiatric unit were offered the opportunity to participate in a daily morning 40- minute walk led by an activity supervisor. After discharge, outcomes for patients who had regularly participated in the walking group (n=35) and patients who had not participated (n=49) were compared for length of stay during their period of admission and Clinical Global Impression-Severity (CGI-S) and Depression Anxiety Stress Scales (DASS) scores measured at admission and discharge.
