本研究旨在评估胃癌 (GC) 患者的生活方式相关行为，并调查 GC 诊断后的时间与这些行为之间的关联。本研究纳入了 29,478 名年龄 ≥ 40 岁的成年人（包括 338 名 GC 患者）参加2014-2021年韩国国民健康与营养检查调查的人。多元logistic回归分析探讨了GC诊断后的时间（5年前诊断出GC的患者[<5岁组]和5年前诊断出GC的患者[≥5岁组]）与生活方式因素之间的关联。根据年龄和性别进行亚组分析。无论诊断后的时间如何，GC 组的当前吸烟率并不低于健康组。与健康对照组相比，<5 岁组的每月酒精摄入量较低（比值比 [OR]，0.450；95% 置信区间 [CI]，0.275-0.736）。与健康对照组相比，≥5岁组的力量训练率较低（OR，0.548；CI，0.359-0.838）。针对≥5岁组的亚组分析显示，力量训练率显着较低，尤其是年龄≥65岁的患者和男性患者（OR，分别为0.519和0.553；CI，分别为0.302-0.890和0.340-0.901）。临床医生应该即使在 GC 诊断后 5 年后，仍继续对患者进行生活方式行为改变方面的教育，特别是戒酒。力量训练教育对于 ≥65 岁的患者或男性患者尤其重要。版权所有 © 2024。韩国胃癌协会。

This study was performed to assess the lifestyle-related behaviors of patients with gastric cancer (GC) and to investigate the associations between the time since GC diagnosis and these behaviors.This study included 29,478 adults (including 338 patients with GC) aged ≥ 40 years who participated in the Korea National Health and Nutrition Examination Survey 2014-2021. Multiple logistic regression analysis explored the associations between the time since GC diagnosis (patients diagnosed with GC less than 5 years ago [<5 years group] and those diagnosed with GC 5 or more than years ago [≥5 years group]) and lifestyle factors. Subgroup analyses were conducted based on age and sex.The current smoking rate was not lower in the GC group than in the healthy group, regardless of time since diagnosis. Compared to the healthy controls, monthly alcohol intake was lower in the <5 years group (odds ratio [OR], 0.450; 95% confidence interval [CI], 0.275-0.736). The ≥5 years group showed a lower rate of strength training (OR, 0.548; CI, 0.359-0.838), compared with the healthy control group. Subgroup analysis focusing on the ≥5 years group revealed a significantly lower rate of strength training, particularly in patients aged ≥65 years and male patients (OR, 0.519 and 0.553; CI, 0.302-0.890 and 0.340-0.901, respectively).Clinicians should continue educating patients on lifestyle behavior modifications, particularly alcohol abstinence, even beyond 5 years after GC diagnosis. Education on strength training is especially important for patients ≥65 years or male patients.Copyright © 2024. Korean Gastric Cancer Association.
