Abstract: Objective To determine the prevalence and influencing factors of hypertension complicated with diabetes mellitus （DM） in elderly residents aged 60 years and over in Shenzhen. Methods From July 2017 to October 2018, cluster sampling method was used to select all registered permanent residents aged ≥60 years from all 51 community health service centers under the jurisdiction of Luohu District, Shenzhen. Questionnaire surveys, physical examinations, and laboratory tests were conducted to collect relevant information. Results A total of 7 982 residents were surveyed, with an average age of 67.68 ± 5.41 years, and more females （57.2%）. Of the all participants, 1 257 were found to have hypertension with DM, with a prevalence rate of 15.7%. Multivariate logistic regression showed that the elderly aged 70-79 years （OR=2.60）, 80-92 years （OR=3.91）, and with overweight （OR=1.82）, obesity （OR=4.16）, abnormal HDL-C （OR=2.12）, and hyperlipidemia （OR=1.59） were more likely to have hypertension complicated with DM; the elderly with higher levels of education and more frequent consumption of fresh fruit, rice and soybean products were less likely to have hypertension with DM; compared with the group with education levels at primary school or below, the OR values of the group with education levels at senior high school/technical secondary school, college/undergraduate and above were 0.82 and 0.65; compared with the group eating fresh fruits<4 times/month, the OR values of the group having fresh fruits 4-11 times/month and≥12times/month were 0.55 and 0.46, respectively; compared with the group eating rice<12 times/month, the OR value of the group eating rice≥12 times/month was 0.46; compared with the group eating soybean products<4 times/month, the OR value of the group eating soybean products≥12 times/month was 0.80. Conclusion The prevalence of hypertension complicated with DM in the elderly in Shenzhen is relatively high. The risk factors for hypertension with DM are old age, overweight, obesity, abnormal HDL-C and hyperlipidemia. Higher education levels and intake of more fresh fruits, rice and soybean products may be the protective factors.
