Abstract Objective To explore the influencing factors of subjective cognitive decline (SCD) in community elderly population. Methods A total of 603 people in the Yongqiao neighborhood Dongguan Street Community in Suzhou City, Anhui Province were selected as the research object by convenient sampling method in December 2020. They were divided into the normal control group with the score ＜five scores and the SCD group with the score ≥five scores. The general information of the people in the Yongqiao district was collected, such as name, sex, age, height, weight, body mass index, education level, annual household income, total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), and high density lipoprotein (HDL) values, TG/HDL ratio, TC/HDL ratio, LDL/HDL ratio, and non-high-density lipoproteins were also converted. Univariate and multivariate logistic regression models were used to analyze the relevant influencing factors in patients with SCD. Results Among the 603 people tested in the community, 395 cases (65.51%) had subjective cognitive decline. Univariate analysis showed that there were statistically significant differences in age, sex, smoking status, drinking status, education level, family annual income, HDL, TC/HDL, and LDL/HDL between the two groups (P＜0.05). Logistic regression analysis showed that gender, age, smoking, drinking, and TC/HDL ratio were risk factors for subjective cognitive decline (OR＞1, P＜0.05), and LDL/HDL ratio was protective factor for subjective cognitive decline (OR＜1, P＜0.05). Conclusion In the elderly population in the community, the prevalence of SCD is high, and there is a correlation between gender, age, smoking, drinking, education, family income, HDL, TC/HDL ratio, LDL/HDL ratio, and SCD. Reasonable intervention should be carried out as soon as possible in the population with risk factors of SCD to delay the development of dementia.
