air conditioning facility and setting of the toilet were observed on site.Results Injury incidence rate in dwelling houses with dark lighting was 20.2% while that in brighter houses was 1.7%

and the differences were statistically significant（p<0.01）.Injury incidence rate in houses with anti-slip floor was 27.0% while that in houses without anti-slip floor was 39.2%

and the differences were statistically significant（p<0.01）.Injury incidence rate in using squatting pan was 12.2% while that in using toilet was 1.9%

and the differences were statistically significant（p<0.01）.Logistic regression analysis was conducted for the investigation result

home environment with injury incidence rate ranked from the top was lighting of the dwelling house（influence coefficient:4.955）

setting of toilet（influence coefficient:4.261）

anti-slip of the floor（influence coefficient:2.885）and air conditioning facility（influence coefficient:0.953）respectively.Conclusion Major risk factors influencing injury among community-dwelling elderly persons were lighting of the dwelling house

setting of toilet and anti-slip of the floor.Removing hidden dangers in time and improving home environment for elderly persons are important measures to prevent injury from happening among elderly persons.
