Incidence of fall related injury in people aged 50 and above and risk factors in 8 provinces in China: a cross-sectional study / 中华流行病学杂志

ABSTRACT

Objective To estimate the incidence and distribution characteristics of fall related injury in people aged ≥50 years in 8 provinces in China and related physiological,psychological and social risk factors.Methods Cross-sectional data were collected from adults aged ≥50 years participating in the World Health Organization (WHO) study on global ageing and adult health (SAGE) round 1 in China.Two-level hierarchical logistic model was used to identify the related factors for fall-related injury.All the models were stratified by living area (urban/rural).Results Estimated incidence of fall related injury (road traffic injury was not included) was 3.2％.Ageing and multiple chronic conditions (OR=2.55,95％CI1.41-4.64) was significantly associated with the incidence of fall related injury in urban area.In rural area,depression (OR=4.33,95％ CI2.52-7.42) and multiple chronic conditions (OR=2.46,95％CI1.37-4.41) were associated with the incidence of fall related injury.Conclusions This study estimated the incidence of fall related injury in adults aged ≥50 years in 8 provinces in China.A significant association between multiple chronic conditions and fall related injury were found in both urban and rural residents.Targeted measures should be taken for the prevention and control of chronic diseases in elderly population.
