Emerging evidence suggests that body weight misperception may be associated with psychological distress among people in developed countries. Participating in physical activity (PA) may negate the association between weight misperception and psychological distress given the well-known benefits of PA on psychological health. This study examined the role of PA in associations between body weight misperception and psychological distress among young South Korean adults.
Data from individuals aged 20 to 39 years who participated in the Fifth Korean National Health and Nutrition Examination Surveys 2010-2012 ( = 6055) was included in the logistic regressions.
The proportions of the respondents under- and over-perceiving their body weight were 66.9% and 0.8% among men and 16.3% and 15.6% among women respectively. A moderating effect of PA participation was observed on the relationship between body weight over-perception and depressed mood (Odds Ratio [OR] = 0.55; 95% Confidence Intervals [95% CI] = 0.34, 0.89). Among individuals who did not meet the recommended vigorous-intensity PA (≥ 20 min/session and ≥ 3 day/week), body weight over-perception was associated with depressed mood (OR = 1.71, 95% CI = 1.19, 2.46) compared to the accurate-perception group. However, no association was observed among those who met the recommended vigorous-intensity PA (OR = 1.52, 95% CI = 0.45, 5.22). Similar patterns were found among physically active versus inactive individuals (recommended walking not met: OR = 2.02, 95% CI = 1.29, 3.15; recommended walking met: OR = 1.28, 95% CI = 0.66, 2.49; muscular strengthening exercises for < 2 day/week: OR = 1.74, 95% CI = 1.21, 2.51; muscular strengthening exercises for ≥ 2 day/week: OR = 1.38, 95% CI = 0.37, 5.14). No relationship existed between body weight over-perception and depressed mood after adjusting for PA.
Participating in regular PA may buffer a potential negative impact of body weight over-perception on depressive mood.
新出现的证据表明，体重误判可能与发达国家人群的心理困扰有关。鉴于体育活动对心理健康的诸多益处，参与体育活动（PA）可能会消除体重误判与心理困扰之间的关联。本研究探讨了体育活动在韩国年轻成年人的体重误判与心理困扰之间的关联中所起的作用。
将参加2010 - 2012年第五次韩国全国健康与营养检查调查（n = 6055）的20至39岁个体的数据纳入逻辑回归分析。
男性中体重感知不足和超重的受访者比例分别为66.9%和0.8%，女性中分别为16.3%和15.6%。观察到体育活动参与对体重超重感知与抑郁情绪之间的关系有调节作用（优势比[OR]=0.55；95%置信区间[95%CI]=0.34，0.89）。在未达到推荐的高强度体育活动（≥20分钟/次且≥3天/周）的个体中，与体重准确感知组相比，体重超重感知与抑郁情绪相关（OR = 1.71，95%CI = 1.19，2.46）。然而，在达到推荐的高强度体育活动的个体中未观察到关联（OR = 1.52，95%CI = 0.45，5.22）。在有体育活动与无体育活动的个体中也发现了类似模式（未达到推荐步行量：OR = 2.02，95%CI = 1.29，3.15；达到推荐步行量：OR = 1.28，95%CI = 0.66，2.49；每周进行肌肉强化锻炼少于2天：OR = 1.74，95%CI = 1.21，2.51；每周进行肌肉强化锻炼≥2天：OR = 1.38，95%CI = 0.37，5.14）。在调整体育活动因素后，体重超重感知与抑郁情绪之间不存在关联。
参与规律的体育活动可能会缓冲体重超重感知对抑郁情绪的潜在负面影响。
