The prevalence of isolated systolic hypertension in adult populations from the Han, Uygur and Kazakh ethnic groups in Xinjiang, China.
OBJECTIVE
To estimate the current prevalence and epidemiology of isolated systolic hypertension (ISH) among adult populations from different ethnic groups in Xinjiang province and to further establish a theoretical basis for developing personalized therapeutic strategies for hypertensive populations.


METHODS
To analyze the prevalence and risk factors of ISH in different ethnic groups in Xinjiang province, a cluster sampling method was adopted to conduct a cross-sectional study on people aged 35 years and older from the Han, Uygur and Kazakh populations in the Urumqi, Kelamayi, Hetian, Zhaosu, Fukang, Tulufan and Fuhai.


RESULTS
A total of 14,618 adults were surveyed with a response rate of 88.80%. The overall prevalence of ISH was 11.95% (men: 10.84% vs women: 12.92%); the prevalence of ISH in women was significantly higher (χ(2) = 15.06, p = 0.00) than that in men. The prevalence varied significantly with age (χ(2) = 822.71, p = 0.00) and increased in the elderly (χ(2) = 769.59, p = 0.00). A logistic regression analysis revealed that age, obesity, diabetes and dyslipidemia are major risk factors for ISH; patients with hypertension combined with obesity or diabetes are at a high risk of ISH.


CONCLUSIONS
The prevalence of ISH in Xinjiang is higher than average and exhibits a gender difference. There is a trend of increased prevalence with increasing age. Populations with obesity, diabetes or dyslipidemia, and patients who have hypertension combined with obesity and/or diabetes, should be aware of early preventive interventions.
