The purpose of this study is to explore the smoking-related behaviors of people ≥60 years of age with respiratory diseases in Shangqiu area. A total of 550 patients with respiratory diseases ≥60 years old who were treated at the First People's Hospital of Shangqiu from April 2015 to April 2017 were selected as the survey subjects through random sampling. Among them, there were 351 males and 199 females; the age ranged from 60 to 86 (72.85±5.71) years old. Follow-up until April 2020, and the follow-up was 3 years or more and related information and death information were also collected. The multivariate Cox proportional hazard regression model was used to analyze the influence of smoking behavior in the survey subjects on the death risk of people with respiratory diseases ≥ 60 years old. A total of 550 cases were included in the survey, and 25 cases were lost to follow-up. The effective number was 525, and the survey effective rate was 95.45%. Among the 525 patients, 336 (64.00%) were males and 189 (36.00%) were females. The age ranged from 60 to 86 (72.69±5.64) years old. The education level was mainly high school and technical secondary school, accounting for 39.24% of the total population. The primary diseases included tracheitis/bronchitis, asthma, pneumonia, COPD and lung cancer. Among 525 patients with respiratory diseases ≥60 years old, non-smokers accounted for 11.05% (58/525), smokers accounted for 68.00% (357/525), and quitters accounted for 20.95% (110/525). The duration of smoking was more than 20 years, accounting for 33.33% (175/525). The smoking intensity was mainly moderate, accounting for 33.90% (178/525). The duration of smoking cessation was mainly<5 years, accounting for 8.76% (46/525). Follow-up until April 2020, the mortality rate of 525 patients with respiratory diseases ≥60 years old was 14.10% (74/525). Cox regression analysis showed that smoking duration, smoking intensity, cumulative smoking amount, and duration of smoking cessation were the influencing factors of death in patients with respiratory diseases ≥60 years old in Shangqiu area (P<0.05). It can be seen that smoking duration, smoking intensity, cumulative smoking amount, and smoking cessation duration may be independent risk factors for death in patients with respiratory diseases ≥ 60 years old in Shangqiu area, and may increase the relative risk of death.
探讨商丘地区≥60岁呼吸系统疾病人群吸烟相关行为状况。收集2015年4月至2017年4月在商丘市第一人民医院就诊的≥60岁呼吸系统疾病患者550例作为调查对象，其中男351例，女199例；年龄60~86（72.85±5.71）岁。随访至2020年4月，随访3年及以上，收集相关信息及死亡信息。采用多因素Cox比例风险回归模型分析调查对象吸烟行为对≥60岁呼吸系统疾病人群死亡风险的影响。共纳入调查人数550例，剔除失访病例25例，有效人数525例，调查有效率95.45%；525例患者中，男336例（64.00%），女189例（36.00%）；年龄60~86（72.69±5.64）岁，受教育程度以高中及中专为主，占全部人数的39.24%，原发病包括气管炎/支气管炎、哮喘病、肺炎、COPD及肺癌。525例≥60岁呼吸系统疾病患者中，不抽烟者占11.05%（58/525），吸烟者占68.00%（357/525），戒烟者占20.95%（110/525），吸烟时长以>20年为主，占33.33%（175/525）；吸烟强度以中度为主，占33.90%（178/525）；戒烟时长以<5年为主，占8.76%（46/525）。随访至2020年4月，525例≥60岁呼吸系统疾病患者死亡率为14.10%（74/525）；Cox回归分析，吸烟时长、吸烟强度、累计吸烟量、戒烟时长是商丘地区≥60岁呼吸系统疾病患者死亡的影响因素（P<0.05）。吸烟时长、吸烟强度、累计吸烟量、戒烟时长可能是商丘地区≥60岁呼吸系统疾病患者死亡的独立危险因素，可能增加死亡相对危险度。.
