To test the validity and intra-instrument reliability of the HJ-203 Omron pedometer when worn in different positions, under controlled and free-living conditions.
Cross-sectional.
Forty healthy adults (20 men, 29.5±7.7 years) participated in three controlled tests, i.e. 20 step test, stair climbing (up and down), and treadmill walking (five bouts at different speeds). All participants wore a HJ-203 pedometer in the pants pocket, in a carrier bag, and around the neck. Fifty-four adults (23 men, 33.9±11.1 years) participated in a free-living conditions test, wearing a HJ-203 in the pants pocket and around the neck during one day.
During controlled tests, absolute percentage error ranged between 0.1% and 14.0%. Accuracy was influenced by wearing position (p<0.001), walking speed (p<0.001), and wearing position×walking speed (p=0.001). Accuracy was poor for pedometers worn in the pants pocket, especially at slower speeds; and best when worn around the neck. During free-living conditions, APE ranged between 30.7% and 36.9% and did not differ statistically between pants pocket and neck position. Intra-instrument reliability varied for controlled tests (ICC=0.14-0.96) and was acceptable during free-living conditions (ICC=0.94).
The HJ-203 Omron pedometer showed acceptable accuracy for all wearing positions during stairs walking and treadmill walking at higher speeds; but limited accuracy during free-living conditions when worn at non-traditional wearing positions (necklace and pants pocket). Reliability was acceptable during treadmill walking at higher speeds and free-living conditions.
在受控和自由生活条件下，测试 HJ-203 欧姆龙计步器佩戴在不同位置时的有效性和仪器内信度。
横断面研究。
40 名健康成年人（20 名男性，29.5±7.7 岁）参与了三项对照测试，即 20 步测试、爬楼梯（上下）和跑步机步行（以不同速度进行五次）。所有参与者均在裤子口袋、携带袋和脖子上佩戴 HJ-203 计步器。54 名成年人（23 名男性，33.9±11.1 岁）在一天内佩戴 HJ-203 计步器，在裤子口袋和脖子上各佩戴一个计步器，参与自由生活条件测试。
在对照测试中，绝对百分比误差在 0.1%至 14.0%之间。准确性受佩戴位置（p<0.001）、行走速度（p<0.001）和佩戴位置×行走速度（p=0.001）的影响。在裤子口袋中佩戴计步器的准确性较差，尤其是在较慢的速度下；而在脖子上佩戴的准确性最佳。在自由生活条件下，APE 在 30.7%至 36.9%之间，裤子口袋和脖子位置之间无统计学差异。仪器内信度在对照测试中变化（ICC=0.14-0.96），在自由生活条件下可接受（ICC=0.94）。
HJ-203 欧姆龙计步器在楼梯行走和较高速度跑步机行走时，所有佩戴位置的准确性均可接受；但在非传统佩戴位置（项链和裤子口袋）时，自由生活条件下的准确性有限。在较高速度跑步机行走和自由生活条件下，可靠性可接受。
