Prevalence of H-type hypertension and its risk factors among residents aged 35 years and older in Minhang District of Shanghai

Objective To investigate the prevalence of H-type hypertension and its risk factors among residents aged 35 years and older in Minhang District of Shanghai. Methods A multistage randomized sampling method was used to select the participants. Questionnaires, physical measures and laboratory tests were conducted among all participants. Logistic regression model was used to analyze the influencing factors of H-type hypertension. Results A total of 3 059 valid data were obtained in the study. The prevalence of H-type hypertension was 47.04% in residents aged 35 years and older. Participants with H-type hypertension accounted for 87.95% of all patients with hypertension in Minhang District. Results of multivariate logistic regression analysis showed that male gender (OR=1.44, 95% CI:1.21-1.73), the age of 45 years and older (OR=2.05, 95% CI:1.46-2.88), overweight (OR=1.67, 95% CI:1.40-2.00) and fat (OR=2.80, 95% CI:2.13-3.70), hypertension grade 2 and 3 (OR=13.42, 95% CI:8.97-20.06), diabetes (OR=1.66, 95% CI:1.35-2.04), high creatinine (OR=2.84, 95% CI:1.35-5.99), low folic acid (OR=1.46, 95% CI:1.23-1.73) and low vitamin B12 levels (OR=1.22, 95% CI:1.03-1.45) were risk factors of H-type hypertension. Conclusions There was a high prevalence of H-type hypertension in residents of Minhang District. Intervention programs for risk factors should be carried out in community residents to prevent and control H-type hypertension.
