Abstract:Objective To analyze the major risk factors of cardiovascular diseaseand their aggregationin the elderly aged 65 years and above receiving free services from the basic public health service project in Qionglai City, and to provide a basis for promoting the health of the elderly. Methods Based on the data about physical examination of the elderly aged 65 years and above in the basic public health service project in Qionglai City in 2020. Chi-square test or chi-square test for trend was employed to analyze the prevalence of cardiovascular disease risk factors in populations. Binary logistic regression analysis was used to analyze the clustering of cardiovascular disease risk factors in populations with different demographic and social characteristics. Results There were 96.00% of the elderly with one or more risk factors for cardiovascular disease and 53.77% of the elderly with aggregation of three or more than risk factors for cardiovascular disease. The first risk factor of single cardiovascular disease was hypertension, with a prevalence rate of 64.51%. Statistically significant differences existed in the prevalence rate of hypertension among populations with different ages, occupations and medical payment methods (all P<0.001). Among the above-mentioned three kinds of populations, the prevalence rate of hypertension was found to be the highest in the age group of 75 years and above (68.19%), workers specializing in production/transportation/service industry (71.38%), and population with commercial/public medical insurance (78.81%). There were statistically significant differences in the aggregation risk of ≥3 cardiovascular disease risk factors among populations with different genders, occupations, marital status, medical payment methods, and ages (all P<0.05). As for the aggregation risk of ≥3 cardiovascular disease risk factors, the risk of males was 1.479 times that of females, the risk of production/transportation/service industry workers was 1.582 times that of mental workers, the risk of the divorced population was 1.539 times that of the married population, and the risks of urban employees with basic medical insurance and populations with commercial/public medical insurance were 1.814 times and 1.994 times that of poverty population with relief medical care, respectively. The proportions of aggregation of ≥3 cardiovascular disease risk factors in the age groups of 65-79 years and 80 years and above were 55.09% and 44.64%, respectively. Conclusion The prevalence and aggregation exposure of cardiovascular disease risk factors were serious in the elderly receiving services from the basic public health service project in Qionglai City. Comprehensive intervention projects should be conducted on population with important socio-demographic characteristics.
