To established population norms for pedometer determined step counts in older Australians.
A representative sample of 684 participants over the age of 55 years wore a pedometer for a week in Newcastle, Australia.
Response rate was 32%. Median daily step count was 8605 in those aged 55-59 years declining to 3778 in those over 80 years old. The proportion who reached 8000 steps per day was 62% in those 55-59 years and 12% in those over 80 years. Daily step counts were highest on Thursdays and Fridays and least on Sundays. Weekend days had on average 620 less steps than weekdays. After adjusting for age, there was a negative association of step count with body mass index >30, and with a history of arthritis but no significant association with other demographic variables.
Pedometry is feasible in an elderly sample, and research involving pedometers must take days of the week into account.
确定澳大利亚老年人通过计步器测量的步数的人群标准。
在澳大利亚纽卡斯尔，对684名55岁以上的参与者进行代表性抽样，让他们佩戴计步器一周。
回复率为32%。55 - 59岁人群的每日步数中位数为8605步，80岁以上人群则降至3778步。每天达到8000步的比例在55 - 59岁人群中为62%，在80岁以上人群中为12%。周四和周五的每日步数最高，周日最少。周末的步数平均比工作日少620步。在调整年龄后，步数与体重指数>30以及关节炎病史呈负相关，但与其他人口统计学变量无显著关联。
计步在老年样本中是可行的，涉及计步器的研究必须考虑一周中的日期。
