| Objective To investigate the prevalence of osteoporosis and related influencing factors in the elderly females with coronary heart disease, so as to provide more theoretical basis for the coordinated prevention and treatment of the two diseases. Methods 181 elderly female patients with a diagnosis of coronary heart disease were successfully collected, and performed bone density testing, and investigated the basic situation, including basic information such as age, family, height, weight, income, and place of residence, and so on. According to the presence or absence of osteoporosis, they were divided into an observation group and a control group. The prevalence and influencing factors of osteoporosis in elderly women with coronary heart disease were analyzed by a single factor and multi-factor Logistic regression, and the model was predicted by combining with the ROC curve. Results There are 110 patients with coronary heart disease and osteoporosis, the prevalence rate is 60.8%, and the incidence is higher in rural high-income people and urban low-income people (P<0.05); Univariate analysis showed that age, BMI, hypertension, diabetes, coronary heart disease family history, smoking history, and marital status were distributed differently in the two groups (P<0.1); Multivariate logistic regression analysis showed that advanced age, hypertension, diabetes, family history of coronary heart disease, smoking history and BMI≥28 kg/m2 were the risk factors for osteoporosis in coronary heart patients (P<0.05); The results of ROC curve: AUC=0.820, P<0.001.Conclusion ①Old age, hypertension, diabetes, family history of coronary heart disease, smoking history, and BMI≥28 kg/m2 are the independent risk factors for osteoporosis in the elderly female coronary heart patients. These risk factors are consistent with coronary heart disease risk factors. Therefore, there is a common etiological basis for the cooperative prevention and treatment of the two diseases; ②Among these influencing factors, social factors cannot be ignored, and changing lifestyles and increasing understanding of the disease may reduce its incidence. |
