Abstract:Objective Through the analysis of the epidemiological characteristics and influencing factors of hypertension and prehypertension in five population inspection reports in Nanjing from 2008 to 2016,to provide a basis for the government and units to carry out targeted hypertension prevention and control measures.Methods The blood indicators,blood pressure,and BMI values of the five populations of Nanjing public security system,education system,medical and health system,general public servants,and other public institutions from 2008 to 2016 were selected,and a database was established for retrospective analysis.Results A total of 83 377 physical examinations were included,including 61 001 males and 22 376 females,with an average age of 56.63 years.The prevalence of hypertension increased year by year in the group >80 years old,and the prevalence of prehypertension increased year by year in the group ≤40 years old.The 80-year-old group decreased year by year,and the difference was statistically significant (P<0.05 ).The prevalence of hypertension in the public security system was decreasing year by year,and the prevalence of prehypertension in the public security system was increasing year by year,the difference is statistically significant (P<0.05 ).The prevalence of hypertension is related to advanced age,men,health and education industries,BMI≥24,decreased HDL-C,increased LDL-C,increased TC,increased TG,increased fasting blood glucose,increased glycosylated hemoglobin,and increased uric acid High and increased creatinine were related,and the difference was statistically significant (P<0.01 ).Conclusion The prevalence of hypertension in the population included in this study is significantly higher than the prevalence rates of adult hypertension reported in my country.There are differences in the prevalence of hypertension and prehypertension among industries,and the prevalence of hypertension and prehypertension There are differences in each age group.
