Trend of drowning mortality among children and adolescent in Chongqing, 2012–2021

Abstract

Objective To analyze the trend change of the drowning mortality among children and adolescents in Chongqing, 2012–2021, and to provide suggestion for drowning prevention and control.

Methods Drowning death cases (ICD–10: W65.0–W74.9) among children and adolescents in Chongqing from 2012 to 2021 were derived from Chongqing death registration system. The difference of the drowning mortality between male and female, urban and rural area were compared by Chi-square test. The trend change of the drowning mortality between 2012 and 2021 was analyzed by annual percent change ( APC).

Results The mortality and ASMR of drowning among children and adolescents decreased from 9.57/10 ⁵, 9.42/10 ⁵ in 2012 to 2.80/10 ⁵, 2.83/10 ⁵ in 2021 significantly ( t =10.93, 10.52, P<0.01). And its APC were −13.15% and 13.06% respectively. The drowning mortality in male was higher than that in female ( P<0.05). The drowning mortality in rural area was higher than that in urban area ( P<0.05). The mortality of drowning among children aged between 0 and 4 years old, 5 and 9 years old, 10 and 14 years old decreased by 15.30%, 17.80% and 11.40% ( APC = −15.30%, −17.80%, −11.40%, t = 11.11, 9.22, 5.62, P<0.05). The proportion of drowning in natural water field among children and adolescents accounted for about 80%.

Conclusion The mortality of drowning among children and adolescents in Chongqing decreases rapidly. Vulnerable population of drowning includes boys, rural children and adolescents, and children age of 0–14 years old. Comprehensive prevention for drowning should be carried out continuously.

【摘要】 目的 了解 2012—2021 年重庆市儿童青少年溺水死亡率及趋势变化, 为开展溺水干预提供建议。 方法 2012—2021 年重庆市儿童青少年溺水死亡 (ICD–10:W65.0~W74.9) 个案信息来自于重庆市死因监测系统, 对不同性别、地区死 亡率比较米用 χ ² 检验, 死亡率的趋势分析米用年度变化百分比 (annual percent of change, APC) 表示。 结果 重庆市儿童 青少年溺水死亡率与标化死亡率由 2012 年的 9.57/10 万、9.42/10 万下降到 2021 年的 2.80/10 万、2.83/10 万, APC 分别为 −13.15%, 13.06% ( t 值分别为 10.93, 10.52, P 值均<0.01)。2012—2021 年男生溺水死亡率髙于女生, 农村地区溺水死亡率 髙于城市 ( P 值均<0.05)。0~4、5~9、10~14 岁年龄组溺水死亡率分别以年均 15.30%, 17.80% 与 11.40% 下降, 变化趋势差 异有统计学意义 ( APC 分别为 −15.30%, −17.80%, −11.40%, t 值分别为 11.11, 9.22, 5.62, P 值均<0.05)。自然水域是发生 溺水死亡的主要场所, 约占 80%。 结论 重庆市儿童青少年溺水死亡率呈快速下降的趋势, 男性、农村儿童青少年、0~14 岁儿童是溺水防控的重点人群, 应继续加强溺水的综合防控。
