Background. Morbidity and mortality linked to injury has become an increasingly important public health concern worldwide, especially in developing countries. Despite the potentially severe nature of torso injury, little is known about the population-based epidemiology of torso injury in sub-Saharan Africa. Objectives. To determine the incidence, identify common mechanisms, and assess the socioeconomic consequences of torso injury in Cameroon. Methods. We performed a torso injury sub-analysis of a larger descriptive cross-sectional community-based study on injury epidemiology in the preceding 12 months in the Southwest region of Cameroon. Sampling was done using the three-stage cluster sampling technique. The differences between groups were evaluated using χ 2 and adjusted Wald tests. Results. We identified 39 cases of torso injuries out of 8 065 participants, providing a yearly incidence estimate of 488 (95% confidence interval (CI) 356 -668) per 100 000 person-years. Road traffic injury was the most common mechanism of torso injury. The median (interquartile range (IQR)) cost of treatment for torso injury was USD58 (10 -137), over four times the median (IQR) cost for non-torso injury at USD12 (3 -43) (p=0.0004). About half of affected households (51%) reported being unable to afford necessities such as rent and food after injury v. 33% of households with members with non-torso injuries (p=0.018). Conclusion. Torso injuries have an incidence of 488/100 000 person-years, and road traffic injuries account for the majority of the injuries. Road traffic control measures and trauma care strengthening may reduce the impact of torso injuries and injuries in Cameroon.

Introduction:Extremity injuries are a leading cause of morbidity in low- and middle-income countries (LMICs), often resulting in marked short-term and long-term disabilities. Most of the existing knowledge on these injuries originates from hospital-based studies; however, poor access to health care in LMICs limits these data because of inherent selection bias. This subanalysis of a larger population-level cross-sectional study in the Southwest Region of Cameroon aims to determine patterns of limb injury, treatment-seeking behaviors, and predictors of disability.Methods:Households were surveyed in 2017 on injuries and subsequent disability sustained over the previous 12 months using a three-stage cluster sampling framework. Subgroups were compared using the chi square, Fisher exact, analysis of variance, Wald, and Wilcoxon rank-sum tests. Logarithmic models were used to identify predictors of disability.Results:Of 8,065 subjects, 335 persons (4.2%) sustained 363 isolated limb injuries. Over half of the isolated limb injuries (55.7%) were open wounds while 9.6% were fractures. Isolated limb injuries most commonly occurred in younger men and resulted from falls (24.3%) and road traffic injuries (23.5%). High rates of disability were reported, with 39% reporting difficulty with activities of daily living. Compared with individuals with other types of limb injuries, those with fractures were six times more likely to seek a traditional healer first for care (40% versus 6.7%), 5.3 times (95% CI, 1.21 to 23.42) more likely to have any level of disability after adjustment for injury mechanism, and 2.3 times more likely to have difficulty paying for food or rent (54.8% versus 23.7%).Discussion:Most traumatic injuries sustained in LMICs involve limb injuries and often result in high levels of disability that affect individuals during their most productive years. Improved access to care and injury control measures, such as road safety training and improvements to transportation and trauma response infrastructure, are needed to reduce these injuries.
