Abstract:
This cross-sectional study aimed to examine the association of various aspects of physical activity, including intensity, duration, type, and purpose, with the phase angle (PhA), an objective indicator of health, in Korean adults after stratification by sex. Data from the 2022 Korean National Health and Nutrition Examination Survey, a nationwide, representative, population-based survey, were used. In total, 3996 participants were included in the study. Participants self-reported their weekly intensity, frequency, duration of engagement in physical activity. PhA was categorized into two groups on the basis of sex-specific averages. Multiple logistic regression analysis was used to investigate the relationship between physical activity and PhA, and proportional odds logistic regression analysis was performed to determine the association between physical activity and different subclasses of PhA. A positive association was found between sufficiently active aerobic physical activity and PhA compared with inactive physical activity (sufficiently active, male: odds ratio = 1.952, 95% confidence interval = 1.373-2.776; female: odds ratio = 1.333, 95% confidence interval = 1.019-1.745). This association was further strengthened when aerobic physical activity was accompanied by muscle-strengthening activity (sufficiently active with muscle-strengthening activity, male: aOR = 2.318, 95% CI = 1.512-3.554; female: aOR = 1.762, 95% CI = 1.215-2.556) and vigorous-intensity activities (sufficiently active with sufficient vigorous-intensity activity, male: aOR = 2.785, 95% CI = 1.647-4.709; female: aOR = 2.505, 95% CI = 1.441-4.356) and when there was more leisure-time physical activity than occupational physical activity (sufficiently active with more leisure-time physical activity, male: aOR = 2.158, 95% CI = 1.483-3.140; female: aOR = 1.457, 95% CI = 1.078-1.969). Furthermore, the inclusion of muscle-strengthening activity made a significant difference in the values of PhA for males with insufficiently active physical activity (aOR = 2.679, 95% CI = 1.560-4.602). For females with highly active physical activity (aOR = 1.521, 95% CI = 1.068-2.166), the inclusion of muscle-strengthening and vigorous-intensity activities were significantly associated with higher values for PhA. This study can be utilized to provide specific suggestions for better health programs and can change perception that only occupational physical activity is enough. This study also indicated that PhA can be used for personalized health assessments.
摘要:
这项横断面研究旨在检查身体活动各个方面的关联,包括强度,持续时间,type,和目的,与相位角(PhA),健康的客观指标,在按性别分层后的韩国成年人中。2022年韩国国家健康和营养检查调查数据一个全国性的,代表,以人口为基础的调查,被使用。总的来说,3996名参与者被纳入研究。参与者自我报告他们每周的强度,频率,参与体育活动的持续时间。根据性别特异性平均值将PhA分为两组。采用多因素logistic回归分析研究体力活动与PhA,并进行比例几率逻辑回归分析,以确定体力活动与PhA不同亚类之间的关联。与不活动的身体活动相比,充分活跃的有氧身体活动与PhA之间存在正相关(充分活跃,男性:比值比=1.952,95%置信区间=1.373-2.776;女性:比值比=1.333,95%置信区间=1.019-1.745)。当有氧运动伴随着肌肉强化活动时,这种联系得到了进一步加强(与肌肉强化活动充分活跃,男性:aOR=2.318,95%CI=1.512-3.554;女性:aOR=1.762,95%CI=1.215-2.556)和高强度活动(足够活跃,足够的高强度活动,男性:aOR=2.785,95%CI=1.647-4.709;女性:aOR=2.505,95%CI=1.441-4.356),并且当休闲时间体育活动多于职业体育活动时(足够活跃,休闲时间体育活动更多,男性:aOR=2.158,95%CI=1.483-3.140;女性:aOR=1.457,95%CI=1.078-1.969)。此外,对于体力活动不充分的男性,包含肌肉强化活动的PhA值有显著差异(aOR=2.679,95%CI=1.560-4.602).对于具有高度活跃体力活动的女性(aOR=1.521,95%CI=1.068-2.166),包含肌肉强化和高强度活动与较高的PhA值显着相关。这项研究可用于为更好的健康计划提供具体建议,并可以改变人们对只有职业体力活动就足够的看法。这项研究还表明,PhA可用于个性化的健康评估。
