2015—2024年浙江省常山县老年人跌倒的流行病学特征及变化趋势

Epidemiological characteristics and trends of fall injuries among the elderly in Changshan County of Zhejiang Province, 2015–2024

  • 摘要: 目的 了解浙江省常山县60岁及以上老年人跌倒的流行病学特征及变化趋势,为制定针对性的老年人跌倒防控措施提供依据。方法 收集2015—2024年常山县3家全国伤害监测哨点医院门急诊首次就诊的≥60岁老年人伤害病例资料,采用χ2检验、趋势χ2分析老年人跌倒的流行特征,并采用平均年度变化百分比(AAPC)分析老年人跌倒的变化趋势。结果 2015—2024年常山县共报告≥60岁老年人跌倒病例17 145例,占全人群伤害病例的9.43%,男女性别比为1:1.04;跌倒占全部伤害的比例呈上升趋势(AAPC=3.10%,P<0.001),是老年人伤害门急诊就诊的首位原因(48.41%)。60~<70岁年龄组跌倒构成比呈下降趋势(AAPC=-1.78%,P=0.001),70~<80岁年龄组跌倒构成比呈上升趋势(AAPC=3.41%,P<0.001)。老年人跌倒发生高峰时间段为8:00—12:00(46.20%),主要发生在家中(65.92%);随着年龄增加,家中发生跌倒的比例呈上升趋势(χ2趋势=660.188,P<0.001)。老年人跌倒后伤害性质以骨折为主(38.97%),骨折占比呈上升趋势(AAPC=4.65%,P=0.003),女性骨折占比高于男性;随着年龄的增加,骨折占比呈上升趋势(χ2趋势=183.665,P<0.001)。结论 常山县老年人跌倒防控形势严峻,跌倒为伤害发生的首位原因,且占全部伤害的比例呈上升趋势,发生地点以家中为主,发生后结局以骨折为主。应开展针对性健康宣教,并采取综合的跌倒预防控制策略。

     

    Abstract: Objective To understand the epidemiological characteristics and changing trends of falls among adults aged 60 years and above in Changshan County, Zhejiang Province, and to provide evidence for developing targeted fall prevention and control measures for the elderly. Methods Data on first-visit injury cases of adults aged ≥60 years from outpatient and emergency departments of three national injury surveillance sentinel hospitals in Changshan County during 2015-2024 were collected. The chi square test and chi-square test for trend were used to analyze the epidemiological features of elderly falls, and the average annual percent change (AAPC) was applied to evaluate the temporal trends of falls. Results A total of 17 145 fall cases among adults aged ≥60 years were reported in Changshan County from 2015 to 2024, accounting for 9.43% of all injury cases across all age groups, with a male tofemale sex ratio of 1:1.04. The proportion of falls among all injuries showed an increasing trend (AAPC = 3.10%, P < 0.001), and falls ranked as the leading cause of outpatient and emergency injury visits among the elderly (48.41%). The constituent ratio of falls declined in the 60-<70 years age group (AAPC = -1.78%, P = 0.001), while it increased in the 70-<80 years age group (AAPC = 3.41%, P < 0.001). Falls predominantly occurred between 8:00 and 12:00 (46.20%), and most events took place at home (65.92%). The proportion of home-occurred falls increased with advancing age (χ2 trend = 660.188, P < 0.001). Fracture was the principal nature of injury following falls (38.97%), and its proportion presented an upward trend (AAPC = 4.65%, P= 0.003); females had a higher proportion of fractures than males. The proportion of fractures rose as age increased (χ2trend = 183.665, P < 0.001). Conclusion Fall prevention and control faces severe challenges in Changshan County. Falls are the leading cause of injuries and their proportion among all injuries is on the rise. Most falls occur at home, and fractures are the major consequent injury outcome. Targeted health education and comprehensive fall prevention and control strategies should be implemented.
