A minority of adults in developed countries engage in sufficient physical activity (PA) to achieve health benefits. This study aims to identify modifiable perceived resources and barriers to PA among New Zealand adults.
Secondary analysis of a 2003 nationally representative cross-sectional mail survey, stratified by region, age, and ethnicity, and analyzed utilizing ordinal logistic regression.
Overall, n = 8038 adults responded to the survey, of whom 49% met updated guidelines for sufficient PA. Perceived accessibility of local resources was associated with PA; however, for some resources there was more awareness among individuals whose predominant activity was not commonly associated with that resource (eg, health clubs and walkers). Perceived local environmental barriers demonstrated negative (steep hills, crime, dogs) and positive (unmaintained footpaths) associations. The absence of perceived environmental barriers was strongly associated with increased activity, suggesting the number of barriers may be a critical factor.
Complex relationships between perceptions of local environments and activity patterns among adults were found. Although complex, these results demonstrate positive associations between awareness of resources and perceived lack of barriers with being sufficiently physically active for health. Therefore, investments in provision and/or promotion of local resources have the potential to enable active healthy communities.

Little is known about the relationships between objectively measured commute distance with actual and perceived transport-related physical activity (TPA) engagement.
A telephone survey assessed travel behaviors to place of work/study within an adult sample (n = 772) residing in New Zealand.
Overall, 50% of respondents perceived they could, and 10% of the sample actually did, use TPA modes to commute to their occupation for distances less than 5 km. Differences between TPA perceptions and engagement existed for all distance classifications, and prevalence declined as distances increased.
Differences between TPA engagement and perceptions were evident. Actual and perceived TPA engagement levels declined as commute distance increased.

Breaks in sedentary behavior are associated with reduced body size in general populations. This study is the first to consider the relationship between objectively assessed sedentary breaks and body size in Pacific children and their mothers.
Pacific children aged 6 years (n = 393) and their mothers (n = 386) residing in New Zealand were invited to participate in 2006. Sedentary time was assessed via accelerometry. Average frequency, duration, and intensity of breaks in sedentary time per hour were calculated. Waist circumference was assessed and demographic factors collected via questionnaire. Relationships between waist circumference and potential associated factors for participants were assessed using linear regression analyses.
Accelerometer data were obtained from 126 children (52 boys) and 108 mothers. Mean (standard deviation) waist circumference values for mothers and children were 114 cm (20.1 cm) and 59.4 cm (7.8 cm), respectively. For mothers, time spent sedentary and being an ex/nonsmoker were positively related to waist circumference. For children, watching television every day and having a mother with a high waist circumference was associated with a greater waist circumference.
Strategies that focus on reducing sedentary time in Pacific mothers and on encouraging television free days in young Pacific children are recommended.
