Insights
Chronic heart failure (CHF) affects 4.30% of Xinjiang's elderly population, with higher prevalence in Kazakh and Uighur ethnic groups and increasing rates with age. Atrial fibrillation, hypertension, and coronary heart disease are significant risk factors.
Area of Science:
- Cardiology and Geriatric Epidemiology
- Public Health and Population Studies
Context:
- Chronic heart failure (CHF) poses a significant health burden on aging populations globally.
- Understanding the epidemiological characteristics of CHF in diverse ethnic groups within specific regions is crucial for targeted interventions.
- Xinjiang, a region with a diverse ethnic makeup, requires specific research into its elderly population's cardiovascular health.
Purpose:
- To determine the prevalence and distribution of chronic heart failure (CHF) in the elderly population (≥60 years) of Xinjiang.
- To identify risk factors and common co-existing cardiovascular diseases associated with CHF across different ethnic groups in Xinjiang.
- To analyze the variations in CHF prevalence based on ethnicity, gender, and age within the studied population.
Summary:
- A cross-sectional study involving 3,858 participants in Xinjiang revealed a 4.30% prevalence of CHF in individuals aged 60 and over.
- Prevalence rates varied significantly among ethnic groups (Han, Uighur, Kazakh), with higher rates observed in males and increasing prevalence with advancing age.
- Atrial fibrillation was identified as an independent risk factor, while hypertension and coronary heart disease were the most common comorbidities.
Impact:
- The findings highlight significant ethnic and age-related disparities in CHF prevalence within Xinjiang's elderly population.
- This research underscores the importance of considering specific ethnic and demographic factors in the prevention and management of CHF.
- Strengthened epidemiological studies on high-risk populations are essential for developing effective public health strategies to combat chronic heart failure in the region.
Objective:
To investigate the prevalence and distribution of chronic heart failure (CHF) in the aged population of Xinjiang.
Methods:
Four-stage random sampling method was employed in this cross-sectional study to analyze the prevalence, risk factors and combined cardiovascular diseases of heart failure among different ethnic groups in aged (≥60 years and over) population of Xinjiang. Sample of studied population was recruited from 6 different regions in Xinjiang, namely Urumqi, Karamay, Fukang, Turfan Basin, Hetian and Ili Kazakh Autonomous Prefectures.
Results:
3 858 participants were surveyed, with the response rate as 89.14% . The prevalence of CHF was 4.30% in this cohort, including 2.74% in Han, 5.25% in Uighur and 6.32% in Kazakh ethnic groups respectively. The prevalence rates of CHF in different ethnic groups were significant different, statistically (χ(2) = 22.62, P = 0.00). Prevalence in males was 5.50%, predominant in the CHF, with females as 3.13%, and the difference between genders was significant (χ(2) = 13.65, P = 0.00). The prevalence rates of CHF increased in proportion with aging and were 3.39%, 3.68%, 5.12% and 6.82% in the 60-64, 65-69, 70-74, 75 years and over age groups, respectively. The prevalence rates of different age groups showed significant differences (χ(2) = 13.29, P = 0.004), and increased with age. The prevalence of CHF presented a rising trend (χ(2) = 12.07, P = 0.001).
Results:
of this study showed that atrial fibrillation was an independent risk factor for CHF (OR = 5.20, 95%CI: 2.32-11.70 and OR = 5.54, 95% CI:3.83-8.02). The most common combined single cardiovascular disease appeared to be hypertension(50 cases, the constituent ratio was 30.12%), followed by coronary heart disease (12 cases, 7.23%).
Conclusion:
The prevalence of heart failure in population over 60 years was high in Xinjiang, and there showed ethnic differences. Hypertension and coronary heart disease were the basic cardiovascular diseases combined with heart failure in the various ethnic groups in Xinjiang. To strengthen epidemiological study on those high risk populations related to chronic heart failure was important on the strategies of prevention and treatment to this health problem.
