Abstract

Aim

This study investigated the association of physical activity (PA) levels with all-cause and cardiovascular disease (CVD) mortality risks stratified by adiposity and age.

Methods

Participants (36 703; mean age: 49.1; 57.1% women) were selected from the Korea National Health and Nutrition Examination Survey 2007–2013. A Cox proportional hazards model was used to examine the association between PA and mortality across different adiposity categories and ages.

Results

Median follow-up was 9.22 years; 2393 individuals died, including 538 with CVD. Compared with normal-weight controls, underweight individuals had increased all-cause mortality risk (hazard ratio [HR]: 1.60, 95% confidence interval [CI]: 1.33–1.79). The overweight and obese groups demonstrated reduced mortality risks (HRs: 0.75 [95% CI: 0.67–0.84] and 0.59 [95% CI: 0.51–0.67], respectively). Mortality risk based on abdominal obesity had an HR of 1.22 (95% CI: 1.08–1.37). PA protected against mortality risk most in the obese group performing more than 1000 MET-min/week and was particularly significant among those who were underweight and obese aged 65 and older.

Conclusions

Overweight and obese Asian individuals (based on body mass index) had a lower mortality risk than those with normal body mass index, whereas obesity based on waist circumference was associated with increased mortality. PA protected against mortality across various weight categories, especially in individuals aged ≥65. Geriatr Gerontol Int 2024; 24: 1156–1164.

体力活动水平与不同肥胖程度的死亡率之间的关系：亚洲特定年龄人群的纵向研究。

目的：本研究调查了体力活动（PA）水平与全因和心血管疾病（CVD）死亡风险的关系，并根据脂肪含量和年龄进行了分层：研究对象（36 703 人；平均年龄 49.1 岁；57.1% 为女性）选自 2007-2013 年韩国国民健康与营养调查。结果：中位随访时间为 9.22 年：中位随访时间为 9.22 年；2393 人死亡，其中 538 人死于心血管疾病。与正常体重对照组相比，体重不足者的全因死亡风险增加（危险比 [HR]：1.60，95% 置信区间 [CI]：1.33-1.79）。超重组和肥胖组的死亡风险降低（危险比分别为 0.75 [95% CI：0.67-0.84] 和 0.59 [95% CI：0.51-0.67]）。基于腹部肥胖的死亡风险的 HR 为 1.22（95% CI：1.08-1.37）。在每周运动量超过1000 MET-min的肥胖人群中，体育锻炼对降低死亡风险的作用最大，在体重过轻和65岁及以上的肥胖人群中，体育锻炼对降低死亡风险的作用尤为显著：结论：超重和肥胖的亚洲人（基于体重指数）的死亡风险低于体重指数正常的人，而基于腰围的肥胖与死亡率增加有关。不同体重类别的人，尤其是年龄≥65岁的人，通过活动可降低死亡率。Geriatr Gerontol Int 2024; --：-----.
