ABSTRACT
Objective: To study epidemiological characteristics of hypertension in returning nationals and their offspring, and analyze its relative risk factors. Methods: A total of 1 278 returning nationals were randomly selected as nationals group, and 1 267 local residents were regard as local residents group. All subjects received questionnaire and physical examination. Multifactor logistic regression analysis was used to analyze relative risk factors. Results: Incidence rate of hypertension was 19.25% in nationals group (standardized rate was 16.23%), which was significantly higher than 13.10% of local residents group (standardized rate was 11.04%) (χ2=17.72, P<0.01). As age increased, incidence rate of hypertension showed an increasing trend, which started to significantly rise in 30~ years group. Multi-factor Logistic regression analysis indicated that factors entered equation were gender, age, alcohol drinking, high-fat diet, dyslipidemia, body mass index, genetic factor and exercises, and their OR values were 1.76, 2.37, 3.62, 2.98, 1.86, 3.15, 3.12 and 2.74 respectively. Conclusion: Incidence rate of hypertension in returning nationals is significantly higher than that of local residents. Incidence rate of hypertension of returning nationals showed an increasing trend. Their risk factors were age, alcohol drinking, high-fat diet, dyslipidemia, body mass index, genetic factor and exercises etc.
