Australian guidelines recommend that children participate in at least one hour of physical activity every day. We aimed to measure physical activity participation in a random sample of Australian primary school children and to determine the biological, behavioural, environmental and social influences associated with insufficient daily activity.
We analysed the following cross-section data from a randomly selected sample of children (N=518) aged 5 to 12 years: age, gender, socioeconmic status (SES) indicators, family size, home play equipment availability, transport method to school, and estimated time per week in physical and sedentary activity. Logistic regression analysis was performed to determine variables that were associated with insufficient (<60 minutes) daily activity.
Seventy-six children (15% of the cohort) failed to meet the minimum activity recommendations of 60 minutes of daily activity. These children were significantly less likely to walk or cycle to school (adjusted odds ratio (OR) 0.43; 95% CI=0.24-0.77) or participate in organised sports or activity (OR 0.42; 95% CI=0.28-0.64) and were more likely to spend in excess of 2 hours a day watching television of using a computer for entertainment (OR 2.10 (1.16-3.78). Age, gender, SES and family size were not significantly associated with insufficient activity.
There exists a significant proportion of the paediatric population who are insufficiently active. Interventions to encourage increased activity in this sub-group may be successful if they seek to alter sedentary behaviour (namely television use) and method of transportation to and from school.
澳大利亚指南建议儿童每天至少参加一小时体育活动。我们旨在对澳大利亚小学生的随机样本进行体育活动参与情况的测量，并确定与每日活动不足相关的生物学、行为、环境和社会影响因素。
我们分析了从5至12岁儿童（N = 518）的随机样本中获取的以下横断面数据：年龄、性别、社会经济地位（SES）指标、家庭规模、家中是否有游乐设备、上学交通方式以及每周估计的体育活动和久坐活动时间。进行逻辑回归分析以确定与每日活动不足（<60分钟）相关的变量。
76名儿童（占队列的15%）未达到每日60分钟活动的最低建议。这些儿童步行或骑自行车上学的可能性显著降低（调整后的优势比（OR）为0.43；95%置信区间=0.24 - 0.77），参加有组织的体育活动或运动的可能性也降低（OR为0.42；95%置信区间=0.28 - 0.64），且每天花超过2小时看电视或使用电脑娱乐的可能性更大（OR为2.10（1.16 - 3.78））。年龄、性别、SES和家庭规模与活动不足无显著关联。
相当大比例的儿科人群活动不足。如果旨在改变久坐行为（即看电视）以及上下学交通方式，那么针对该亚组鼓励增加活动的干预措施可能会成功。
