Prevalence and factors associated with self-reported injuries in Nepal: a secondary analysis of the nationally representative cross-sectional STEPS Survey, 2019

Abstract

ObjectiveThis study aims to determine the prevalence and factors associated with injuries in the adult population of Nepal.Design and participantsSecondary analysis of the data from the cross-sectional WHO STEPwise Approach to NCD Risk Factor Surveillance (STEPS) Survey Nepal, 2019. A multistage cluster sample of 5593 adults aged 15–69 years who have been the usual residents of the household for at least 6 months. A binary logistic regression model was employed to identify the determinants of injuries.SettingData were derived from the STEPS Survey Nepal, 2019.Primary and secondary outcome measuresThe primary outcome was injured person defined as one who had road traffic injuries (RTIs), had other serious unintentional/accidental injury, or had been seriously injured in a violent incident within the past 12 months. The secondary outcome measure was factors associated with injuries.ResultsOver 11% of the 4996 study participants reported any injuries during the past 12 months. About 3.75% of the participants experienced a RTI, 4.71% had experienced unintentional injuries other than RTI, while 5.33% had been injured in violent incidents. Individuals belonging to the middle wealth quintile (crude OR (COR)=2.95, 95% CI 1.27 to 6.84) were associated with increased odds of RTIs. By occupation, homemaker (COR=0.45, 95% CI 0.24 to 0.84) was protective against these injuries. Likewise, currently married individuals (COR=3.74, 95% CI 1.37 to 10.17), ever married individuals (COR=3.49, 95% CI 1.08 to 11.25) and individuals not in employment (COR=2.13, 95% CI 1.16 to 3.91) were associated with an increased likelihood of sustaining an intentional injury. Injuries were higher among rural participants.ConclusionsThis study provides the baseline population-based estimates of the prevalence of injuries in Nepal. It describes the mechanisms and risk factors of these injuries. It is hoped that this evidence will serve as a stimulus for future studies to elucidate comprehensive national information about injuries.
