目的通过了解某职业队列人群肺癌患者分布特征10年变化趋势,为确定肺癌高危人群、制定肺癌的预防控制及诊疗措施提供基础数据与科学依据。方法运用整群抽样方法,抽取2001~2010年间该职业队列人群ICD-10分类标准编码为肺癌的住院患者完整的病案资料,进行统计分析,描述该职业队列人群中老年肺癌患者分布特征10年变化趋势。结果 10年该职工医院男性肺癌患者明显高于女性(2.26~22.67)∶1。61岁~年龄段肺癌患者所占比例最大(45.84%);71岁以上肺癌患者构成比与年份存在正相关(rs=0.758,P<0.001),平均增长速度为3.19%。各职业组肺癌患者以采矿工人组及冶炼工人组所占比例最大(占62.13%),其中冶炼工人组肺癌患者构成比例与年份存在正相关(rs=0.551,P<0.001),平均增长速度为3.19%。结论肺癌病死率高,疾病负担重,男性61岁以上及从事采矿、冶炼工作者是肺癌发生的高危人群,应加强该人群的健康教育与防护;冶炼工人肺癌患者逐年增多,应改善该人群的作业环境及加强职业防护,切实提高该人群生命健康质量。
Objective To understand the ten-year trend of the distribution of lung cancer patients in a certain occupational cohort and provide the basic data and scientific basis for the prevention and control of lung cancer and diagnosis and treatment measures for identifying the high-risk population of lung cancer. Methods A cluster sampling method was used to collect the complete medical records of hospitalized patients with ICD-10 classification of lung cancer from 2001 to 2010. The statistical analysis was conducted to describe the distribution characteristics of elderly patients with lung cancer in the occupational cohort for 10 years trend. Results The hospitalized male hospitalized patients with lung cancer were significantly higher than females (2.26 ~ 22.67) in 10 years. The proportion of patients with lung cancer was the highest (45.84%) in the age group of 1.61 years old. The proportion of patients with lung cancer over the age of 71 was positively correlated with the year rs = 0.758, P <0.001) with an average growth rate of 3.19%. The occupational group had the largest proportion of miners and smelting workers (62.13%). The proportion of lung cancer patients in smelting workers was positively related to the year (rs = 0.551, P <0.001), and the average growth rate was 3.19%. Conclusion The mortality rate of lung cancer is high, the burden of disease is heavy. Men over 61 years of age and engaged in mining and metallurgical work are the high risk groups of lung cancer. Health education and protection should be strengthened for this group of patients. The number of lung cancer patients in smelting workers is increasing year by year. Working environment and strengthening occupational protection, and effectively improve the quality of life and health of the population.
