Abstract
OBJECTIVES
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.
METHODS 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.
RESULTS 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.
CONCLUSIONS 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.

본 연구에서는 2014-2015년도 국민건강영양조사자료의 가속도계 자료를 활용하여 한국 성인의 성별, 연령별 케이던스 패턴을 확인하였다. 한국 성인은 하루 평균 약 12시간(약 87%)을 분당 20보 이하의 낮은 케이던스에서 보냈고, 분당 100보 이상의 높은 케이던스에서는 하루 중 단지 약 18분 (약 2%)의 시간을 보냈다. 성별 및 연령대에 따라 약간의 차이는 있으나, 대부분 유사한 양상을 보였다.
Key Message
Korean adults spent approximately 12 hours per day (about 87%) at a low cadence (<20 steps per minute) while spending only about 18 minutes per day (about 2%) at a high cadence (≥ 100 steps per minute). Even though certain amount of differences between sex and age groups do exist, most have shown similar patterns.

Abstract
OBJECTIVES
The study aimed to examine whether simultaneously meeting the combined guidelines of accelerometer-assessed moderate to vigorous physical activity (MVPA) and self-reported muscle-strengthening activity (MSA) was associated with lower odds of metabolic syndrome (MetS) than meeting neither or 1 of the guidelines among the Koreans.
METHODS This cross-sectional analysis included 1,355 participants from the Korea National Health and Nutrition Examination Survey (2014-2015). Logistic regression was used to analyze the associations across groups of MVPA-MSA guideline adherence (meeting neither [reference]; meeting MVPA only; meeting MSA only; meeting both MVPS and MSA) with MetS components (abdominal obesity, hypertriglyceridemia, low high-density lipoprotein cholesterol [HDL-C], hypertension, and hyperglycemia). The odds ratios (ORs) were adjusted for covariates (e.g., sex, age, body mass index, and accelerometer wearing time).
RESULTS MSA only significantly reduced the OR for abdominal obesity (OR, 0.34; 95% confidence interval [CI], 0.13 to 0.91). Meeting both MVPA and MSA reduced the OR for hypertriglyceridemia (OR, 0.59; 95% CI, 0.39 to 0.88) and low HDL-C (OR, 0.46; 95% CI, 0.31 to 0.68). Compared to meeting neither, MVPA only (OR, 0.63; 95% CI, 0.44 to 0.89) and both MVPA and MSA (OR, 0.46; 95% CI, 0.28 to 0.76) significantly reduced the OR for MetS.
CONCLUSIONS Combined MVPA-MSA was more beneficially associated with MetS prevalence than MVPA only and MSA only. Considering that more than 85% of Korean adults do not meet both the MVPA and MSA guidelines, public health actions to promote adherence should be supported.

본 연구는 2014-2015 국민건강영양조사 자료의 가속도계 자료와 신체활동 설문지를 활용하여 한국 성인의 유산소 신체활동과 근력강화운동 지침 충족 여부에 따른 대사증후군의 오즈비를 확인하였다. 그 결과, 유산소 신체활동과 근력강화운동 지침을 모두 충족한 한국 성인은 둘 중 하나의 지침만을 충족하거나, 모두 충족하지 않는 성인에 비해 더 낮은 오즈비를 나타내었다.
Key Message
In this study, the 2014-2015 Korean National Health and Nutrition Examination Survey data, the odds ratio of metabolic syndrome was confirmed according to the guidelines for aerobic physical activities and muscle-strengthening activities were met in Korean adults.
As a result, Korean adults who met both the guidelines for aerobic physical activity and muscle-strengthening activities showed a lower odds ratio than adults who met only one of the guidelines or did not meet both guidelines.
