Insights
Hypertension affects 71.9% of Hainan centenarians, primarily as isolated systolic hypertension. Blood pressure varies by gender and region, with women and eastern regions showing higher risks.
Area of Science:
- Gerontology
- Cardiovascular Health
- Epidemiology
Background:
- Centenarians represent a unique population for studying aging and health.
- Understanding blood pressure profiles in extreme longevity is crucial for public health.
- Hainan province has a high concentration of centenarians, making it a key study area.
Purpose of the Study:
- To investigate blood pressure levels and hypertension influencing factors in Hainan centenarians.
- To establish baseline data for future research on blood pressure in this population.
- To analyze the prevalence and characteristics of hypertension among the oldest old.
Main Methods:
- Cross-sectional study utilizing baseline data from the China Hainan Centenarian Cohort Study (CHCCS).
- Inclusion of 1,002 centenarians with data from questionnaire surveys, physical examinations, and physiological index detection.
- Hypertension prevalence analysis based on the 2018 guidelines for Chinese adults.
Main Results:
- Median systolic blood pressure: 152.0 mmHg; diastolic: 76.0 mmHg; pulse pressure: 76.5 mmHg.
- Hypertension prevalence was 71.9%, with isolated systolic hypertension at 60.1%.
- Women (OR=1.624) and the eastern region had higher hypertension risks compared to men and northern/central regions.
Conclusions:
- High prevalence of hypertension, predominantly isolated systolic hypertension, observed in Hainan centenarians.
- Significant gender and regional disparities in hypertension prevalence exist within this population.
- Findings highlight the need for targeted interventions considering demographic factors in centenarian health.
Abstract:
Objective: To explore the blood pressure levels and the influencing factors of hypertension among Hainan centenarians, and provide basic data for the further blood pressure related studies of the centenarian population. Methods: The baseline data were from China Hainan Centenarian Cohort Study (CHCCS). This cross-sectional data, based on the community population, was a complete sample study of centenarians, including questionnaire survey, physical examination and physiological index detection. A total of 1 002 centenarians were recruited to describe the blood pressure level. According to the guidelines for the prevention and treatment of hypertension in Chinese adults in 2018, the prevalence of hypertension was analyzed. Results: The median levels of systolic blood pressure, diastolic pressure and pulse pressure were 152.0, 76.0 and 76.5 mmHg, respectively. Blood pressure level was higher in females than in males. The prevalence of hypertension was 71.9%, mainly in isolated systolic hypertension with the prevalence of 60.1%. The results of multivariate analysis showed that the risk of hypertension in women was higher than that in men (OR=1.624, 95%CI: 1.155-2.283), and the risk of hypertension in the northern (OR=0.625, 95%CI: 0.434-0.901) and central areas (OR=0.586, 95%CI: 0.346-0.993) was lower than that of the Eastern. Conclusion: The prevalence of hypertension, mainly in isolated systolic hypertension, showing gender and regional distribution differences.

Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
Blood Pressure
Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the...
