The aim of this study was to identify the stepping cadence patterns in Korean adults by using objectively measured accelerometer data to analyze the time spent in each cadence category by sex and age.
During the 2014-2015 Korean National Health and Nutrition Examination Survey, 1,703 males and females aged 19-64 years provided at least 1 valid day of data (wearing an accelerometer ≥ 10 hr/d). The mean cumulative time and percentage per day in 8 cadence categories (0, 1-19, 20-29, 30-59, 60-79, 80-99, 100-119, and ≥ 120 steps/min) by sex and age group were calculated.
Cumulative time and percentage per day decreased across the incremental cadence categories. Participants spent 360.08± 2.56 min/d in the non-movement cadence category and 361.50± 2.28 min/d in the incidental movement cadence category. However, they spent only about 18.1 min/d (2.1%) at ≥ 100 steps/min. Males spent significantly more time in the cadence categories of sporadic movement, purposeful steps, slow walking, and medium walking, but the other categories, except for brisk walking, had higher values in females (p< 0.001). The older age group spent less time in non-movement cadence categories, and the youngest and oldest groups spent more time at a higher cadence (≥ 100 steps/min) than the other age groups. Similar patterns were found in a subgroup analysis by sex.
Korean adults spent most of their time at a low cadence and only a few minutes at a high cadence (≥100 steps/min); this trend was consistent across sex and age groups.
本研究旨在通过使用客观测量的加速度计数据，确定韩国成年人的步频模式，以分析按性别和年龄划分的每个步频类别所花费的时间。
在2014 - 2015年韩国全国健康与营养检查调查期间，1703名年龄在19 - 64岁的男性和女性提供了至少1个有效日的数据（佩戴加速度计≥10小时/天）。计算了按性别和年龄组划分的8个步频类别（0、1 - 19、20 - 29、30 - 59、60 - 79、80 - 99、100 - 119和≥120步/分钟）每天的平均累计时间和百分比。
随着步频类别的增加，每天的累计时间和百分比减少。参与者在非运动步频类别中每天花费360.08±2.56分钟，在偶然运动步频类别中每天花费361.50±2.28分钟。然而，他们在≥100步/分钟时每天仅花费约18.1分钟（2.1%）。男性在零星运动、有目的的步行、慢走和中等速度步行的步频类别中花费的时间明显更多，但除轻快步行外，其他类别女性的值更高（p<0.001）。年龄较大的组在非运动步频类别中花费的时间较少，最年轻和最年长的组在较高步频（≥100步/分钟）下花费的时间比其他年龄组更多。在按性别进行的亚组分析中发现了类似的模式。
韩国成年人大部分时间步频较低，只有几分钟步频较高（≥100步/分钟）；这种趋势在性别和年龄组中是一致的。
