Risk factors for cardiovascular disease from a population-based screening study in Tianjin, China: a cohort study of 36,215 residents

BACKGROUND: Cardiovascular disease (CVD) is a harmful disease that poses a serious threat to human life. By effectively controlling its risk factors, the occurrence and development of CVD can be reduced, and people’s health status and quality of life can be improved. METHODS: A total of 36,215 participants were collected from participants of the Early Screening and Comprehensive Intervention Program for High Risk Population of Cardiovascular Disease in Tianjin on July 31, 2017. We analyzed the relationship between CVD risk and personal information, personal and family medical history, biochemical index, and physical fitness index using Pearson’s chi-squared test with and without Yates’s correction for continuity, and Fisher’s exact test. CVD risk-related factors were examined through logistic regression and decision tree analysis. RESULTS: A personal history of hypertension and apoplexy had a contingency coefficient with CVD risk of more than 0.3. A higher risk of CVD was also found to be associated with biochemical markers of cholesterol, low-density lipoprotein cholesterol, and blood sugar. Logistic regression analysis revealed 12 indicators to be influencing factors of CVD, including age, systolic blood pressure (SBP), diastolic blood pressure (DBP), and the number of people aged >90 in the family. Hypertension, SBP, BMI, cholesterol, and blood glucose were associated with five or more other indicators. CONCLUSIONS: The prevalence of CVD risk factors in Tianjin residents is relatively high. Family disease history and individual physical fitness indicators need to be taken into account during CVD screening and intervention, to reduce the risk of CVD.
