Abstract

Background To investigate the incidence and characteristics of falls in senior citizens at xicheng district community in Beijing, analyse the relationship among falls incidence of the elderly, vision and related falls risk factors, and provide guidance for the elderly on fall prevention and intervention.

Methods The survey covered all the 7 communities on xinjiekou street at xicheng district in Beijing, 1082 elderly people who meet the requirements of over 60 years old were surveyed by systematic sampling method and 1082 investigation forms were received (response rate was 100%), and 1034 effective questionnaires were obtained (effective rate was 95.6%), including 399 men (38.6%) and 635 women (61.4%). Presenting visual acuity (VA) , slit-lamp examination, direct fundus ophthalmoscope, stereopsis test and colour vision examination were measured at 141 old people.

Bivariate analysis was performed by Chi-square test, and multiple analysis was performed by Logistic regression.

Results In 1034 of the elderly, 167 people experienced 189 times falls in the past 2 years and incidence rate of falls among the elderly was 16.2% .It was higher in women (18.0%) than in men (13.3%), there were significant difference in fall incidence rate between women and men (P = 0. 047). The proportions of 141 old people examining vision < 1.0 was 56%, and proportion losing Stereo vision completely was 7.8%. Eye disease inspection results showed that cataract (91.5%) and macular degeneration (33.3%) were the major eye disease in old people. According to our results, the risk factors of falls were cataract (P = 0.004, OR = 1.727, 95% CI: 1.187 ~ 2.512), glaucoma (P = 0.028, OR = 2.507, occupation (P = 0.041), dizziness (P = 0.001, OR = 2.663, 95% CI: 1.503 ~ 4.614), other body disease (P = 0.003, OR = 1.801, 95% CI: 1.217 ~ 2.666), 95% CI: 1.105 ~ 5.684).when compared to the age group from 60 to 64 years old, 70 to 79 years old elderly have more falls risk (P = 0.002).

Conclusions The incidence rate of falls is high in the elderly of Beijing urban communities, and cataract and glaucoma lead to decreased vision are the risk factors of falls.
