We studied factors associated with the weekly occurrence of physical injuries in a rural setting to determine injury-related burden and risk exposures.
Prospective cohort study.
Suna-West subcounty, Migori County, Western Kenya.
390 study participants (subjects) cluster sampled from 92 households, recruited and followed up for 12 weeks, between August and October 2019.
We collected data weekly on occurrence of injuries, individual-level and household-level independent variables using a standard interviewer-administered questionnaire adapted from the WHO survey tool for injuries. Analyses related occurrence of injuries and independent variables using a multilevel Poisson regression model, adjusting for age and sex.
Quantifying injury-related burden and patterns by demographic, occupational and societal risk exposures.
We documented 44 injuries, coming from 38 subjects dwelling in 30 of the 92 study households. On average, each study subject and household experienced 1.2 and 1.5 episodes of injuries across the 12 study weeks. Open wounds and bruises were the most frequent injuries commonly reported among middle-aged (18-54 years) and young (5-17 years) subjects at 32.2 and 7.6 episodes per 1000-person week, respectively. The common cause of injuries among young, middle-aged and old subjects (>54 years) were falls, road accidents and person-related assault or being hit by an object, each at 15.2, 18.9, and 11.4 episodes per 1000-person week, respectively. Subjects not domesticating animals (incidence rate ratio (IRR)=7.6, 95% CI 1.4 to 41.7) and those making a visit outside the local subcounty of residence (IRR=2.2, 95% CI 1.5 to 3.1) were at higher risk of reporting injuries.
We provide evidence of a higher burden of physical injuries associated with demographic, occupational and societal risk exposures with the most injuries resulting from falls. Further studies could better define granular characteristics constituting these factors.
我们研究了农村地区每周发生身体伤害的相关因素，以确定与伤害相关的负担和风险暴露。
前瞻性队列研究。
肯尼亚西部米戈里县萨纳-韦斯特次县。
2019 年 8 月至 10 月期间，从 92 户家庭中以集群方式抽取 390 名研究参与者（研究对象）进行招募和为期 12 周的随访。
我们每周使用经过世卫组织伤害调查工具改编的标准访谈员管理问卷收集伤害发生情况以及个体和家庭层面的独立变量数据。使用多水平泊松回归模型分析伤害发生情况和独立变量，同时调整年龄和性别因素。
我们记录了 44 起伤害事件，涉及居住在 92 户家庭中的 38 名研究对象。平均而言，每位研究对象和家庭在 12 周的研究期间分别经历了 1.2 和 1.5 次伤害事件。开放性伤口和瘀伤是最常见的伤害，常见于中年（18-54 岁）和青年（5-17 岁）人群，分别为每 1000 人周 32.2 和 7.6 例。青年、中年和老年（>54 岁）人群受伤的常见原因分别是跌倒、道路事故和与人有关的袭击或被物体击中，分别为每 1000 人周 15.2、18.9 和 11.4 例。不饲养动物的研究对象（发病率比（IRR）=7.6，95%置信区间 1.4 至 41.7）和离开居住地本地次县的研究对象（IRR=2.2，95%置信区间 1.5 至 3.1）报告受伤的风险更高。
我们提供了与人口统计学、职业和社会风险暴露相关的身体伤害负担较高的证据，其中大部分伤害是由跌倒造成的。进一步的研究可以更好地定义构成这些因素的粒度特征。
