ObjectiveTo determine the current situation of patients with diabetic foot and influencing factors in Jinyang community of Shanghai.

MethodsA total of 1400 patients with diabetes registered in community management from January 2019 through December 2019 were randomly selected for survey. All patients completed the screen for diabetic foot and then were divided into control group （n=159） and observation group （n=1 241） according to the occurrence of diabetic foot. Patient's demographics and medical history were recorded， including gender， age， history of long-term smoking， course of disease， history of trauma infection， fasting blood glucose， 2 h postprandial blood glucose （2hPG）， glycosylated hemoglobin （HbAlc）， blood lipid level， history of hyperglycemia， diabetic nephropathy， and diabetic retinopathy. Univariate and multivariate logistic analyses were performed with these possible influencing factors.

ResultsUnivariate analysis showed that the incidence of diabetic foot was not significantly associated with gender， age， history of trauma infection， course of disease or blood lipid level （P>0.05）， whereas had statistical significance with long-term smoking history， fasting blood glucose and 2-hour diabetes mellitus PG， HbAlc， history of hypertension， diabetic nephropathy and diabetic retinopathy （P<0.05）. Multivariate logistic analysis showed that the incidence of diabetic foot was not statistically associated with gender， age， history of trauma infection， course of disease or blood lipid level （P>0.05）； it was significantly associated with long-term smoking history， fasting blood glucose and 2-hour diabetes mellitus PG， HbAlc， history of hypertension， diabetic nephropathy and diabetic retinopathy （P<0.05）.

ConclusionThere are multiple influencing factors of diabetic foot in Jinyang community. We should take corresponding measures to control the blood glucose level of diabetic patients and reduce the incidence of diabetic foot.
