Prevalence, awareness, treatment, and control of hypertension among very elderly Chinese: results of a community-based study

Dietary patterns, skeletal muscle mass loss, and cardiovascular risk among elderly men: A preliminary cross-sectional study in Sichuan province

The present study investigated the correlation between dietary patterns (DPs) with skeletal muscle mass (SMM) and cardiovascular risks in Sichuan males aged ≥65-years-old. Three major DPs were extracted by principal component analysis: animal-based and processed food, traditional food, and ovo-lacto vegetarian food, which accounted for 14.83%, 14.36%, and 11.86% of the variance, respectively. Adjusted logistic regression analysis showed that animal-based and processed food DP was positively associated with overweight/obesity(OR: 3.25, 95% CI: 1.94-5.46) and dyslipidemia(OR: 3.53, 95% CI: 2.00-6.22). Traditional DP was negatively associated with overweight/obesity(OR: 0.51, 95% CI: 0.36-0.72), dyslipidemia(OR: 0.50, 95% CI: 0.35-0.75), and high blood pressure(OR: 0.54, 95% CI: 0.38-0.77), but positively associated with decreased SMM (OR: 2.21, 95% CI: 1.36-3.16). Ovo-lacto vegetarian DP was negatively associated with dyslipidemia (OR: 0.56, 95% CI: 0.39-0.81) and hyperuricemia (OR: 0.56, 95% CI: 0.39-0.79), but positively associated with decreased SMM (OR: 1.57, 95% CI: 0.74-2.32). How to choose the best DP to control the cardiovascular risks and fight skeletal muscle loss needs further investigation in the future.

A Community-Based Study on Waist-to-Height Ratio: An Indicator for Systolic Hypertension in a Rural Community of Hilly Region

The prevalence of hypertension gradually becomes a serious public health threat as it is a very pertinent risk factor for cardiovascular and cerebrovascular diseases. This study aims to estimate the prevalence of isolated systolic hypertension (ISH) among the hilly region's rural community and identify the indicators of ISH among study participants. A community-based cross-sectional study was conducted among 1220 participants in the rural community of the hilly region. A multistage random sampling technique was applied to recruit the participants. Demographic and anthropometric dimensions were measured to analyze the outcome of the study. The participants' mean age was 44.42 ± 15.54 years, with a majority of 822 female participants (67.40%). The prevalence of ISH was found as 27.45%. A statistically significant positive correlation (p < 0.05) of the waist-to-height ratio (WHtR) and body mass index (BMI) were observed with systolic blood pressure (SBP) in male as well as female participants, whereas BMI and WHtR had no correlation with diastolic blood pressure (DBP). Among female participants, the area under the curve (AUC) for BMI and WHtR was 0.604 (95% confidence interval 0.565-0.643, p-value = 0.020*) and 0.622 (95% confidence interval 0.584-0.660, p-value = 0.020*), respectively. Among male participants, the AUC for BMI and WHtR was 0.574 and 0.592, respectively. Hence, it cannot be considered very satisfactory. The increasing prevalence of ISH in a rural community is also a public health concern. At the preliminary stage, anthropocentric measurements are the primary tool for a family physician while treating the patients. This study concluded that WHtR is a better indicator than BMI for systolic hypertension. Although we have not observed a strong correlation of WHtR with systolic hypertension, it is required to perform future research to support this study's evidence.

Comparison of self-reports and biomedical measurements on hypertension and diabetes among older adults in China

Background

Researchers interested in the effects of health on various life outcomes often use self-reported health and disease as an indicator of true, underlying health status. However, the validity of reporting is questionable as it relies on the awareness, recall bias and social desirability. Accordingly, biomedical test is generally regarded as a more precise indication of the disease.

Methods

Using data from the third wave of China Health and Retirement Longitudinal Study (CHARLS), we selected individuals aged 40–85 years old who participated in both health interview survey and biomedical test. Sensitivity, specificity, false negative reporting and false positive reporting were used as measurements of (dis) agreement or (in) validity, and binary and multinomial logistic regression were used to estimate under-report or over-report of hypertension and diabetes.

Results

Self-reported hypertension and diabetes showed low sensitivity (73.24 and 49.21%, respectively) but high specificity (93.61 and 98.05%, respectively). False positive reporting of hypertension and diabetes were 3.97 and 1.67%, while false negative reports were extremely high at 10.14 and 7.38%. Educational attainment, hukou, age and gender affected both group-specific error and overall error with some differences in their magnitude and directions.

Conclusion

Self-reported conditions underestimate the disease burden of hypertension and diabetes in China. Adding objective measurements into social survey could improve data accuracy and allow better understanding of socioeconomic inequalities in health. Furthermore, there is an urgent need to provide basic health education and physical examination to citizens, and promote the use of healthcare to lower the incidence and unawareness of disease in China.

Effects of Disability Type on the Association between Age and Non-Communicable Disease Risk Factors among Elderly Persons with Disabilities in Shanghai, China

Little is known about differences in the association between age and risk factors of non-communicable diseases (NCDs), according to the disability type in Chinese elderly persons with disabilities. Thus, we examined the effects of these differences in elderly persons with disabilities in Shanghai, China. We evaluated four NCD risk factors (hypertension, hyperglycemia, hyperlipidemia, and overweight) using health data obtained from 20,471 elderly persons with disabilities in 2017. Logistic regression analyses explored differences in the association between age and NCD risk factors according to the disability types, after adjusting for sociodemographic characteristics. We observed significant differences in the association between age and NCD risk factors across disability types; a significant association was observed between older age and higher odds of hypertension (p < 0.001) among subjects with a physical disability. However, the prevalence of hypertension did not significantly differ by age in subjects with multiple disabilities. Interventions for elderly patients whose disabilities are more strongly affected by environmental factors should focus more on reduction of subjects’ barriers to activities through improvements in living and environmental adaptability for physical activities.

Hypertension Prevalence, Treatment and Control in Older Adults in a Brazilian Capital City

BACKGROUND

The diagnosis, treatment and control of arterial hypertension are fundamental for a reduction in cardiovascular outcomes, especially in the elderly. In Brazil, there are few studies that specifically identified these rates in the elderly population.

OBJECTIVE

To verify rates of prevalence, treatment and control of hypertension in elderly people living in the urban area of a Brazilian capital city.

METHODS

A cross-sectional, population-based, randomized, cluster-based study with 912 non-institutionalized elderly individuals (≥ 60 years), living in urban areas in the city of Goiania, Midwest Brazil. Predictor variables were: age, gender, socioeconomic and lifestyle aspects. Blood pressure measurements were performed at home; patients were considered as having arterial hypertension when SBP and/or DBP ≥ 140/90 mmHg or when using antihypertensive drugs (dependent variable). Rates of hypertension treatment and control were evaluated. Variable association analyses were performed by multivariate logistic regression and level of significance was set at 5%.

RESULTS

The prevalence of arterial hypertension was 74.9%, being higher (78.6%) in men (OR 1.4, 95% CI: 1.04-1.92); the treatment rate was 72.6%, with higher rates being observed in smokers (OR 2.06, 95% CI: 1.28-3.33). The rate of hypertension control was 50.8%,being higher in women (OR 1.57, 95% CI: 1.19-2.08).

CONCLUSION

The prevalence rates were high. Treatment and control rates were low and associated with gender, age and lifestyle, indicating the need for early and individual interventions.

Prevalence, awareness, treatment, and control of hypertension among Chinese working population: results of a workplace-based study

We investigated the prevalence, awareness, treatment, and control of hypertension and the related risk factors among Chinese working population. From 2012 to 2013, a total of 37,856 employees aged 18-60 years from 61 workplaces were sampled. Standard questionnaire surveys and physical examinations were undertaken. Multilevel logistic regression models were performed to identify the risk factors. Overall, the age-standardized prevalence of hypertension was 23.3% (95% confidence interval [CI]: 22.9%-23.7%). Among the hypertensives, 47.8% (95% CI: 46.8%-48.8%) were aware of their condition, 20.6% (95% CI: 19.8%-21.4%) were in treatment, but only 8.5% (95% CI: 7.9%-9.1%) had controlled hypertension. White-collar employees had a lower odds of hypertension compared with the blue-collar (odds ratio: 0.77, 95% CI: 0.71-0.84), whereas the state-owned enterprise employees had a higher odds compared with their private enterprise counterparts (odds ratio: 1.69, 95% CI: 1.07-2.65). Lower awareness and treatment were associated with being younger, higher education, and those from workplace without affiliated hospital. Higher occupation status individuals were more likely to be treated but no sign of better control. There is substantial room for improvement in hypertension diagnosis and treatment among the employees. Effective intervention programs are urgently needed at the workplaces.

Prevalence and control of hypertension among a Community of Elderly Population in Changning District of shanghai: a cross-sectional study

BACKGROUND

Hypertension is considered a major public health challenge. It is the most important risk factor for cardiovascular disease and is a prominent risk for China's elderly population. However, few studies have addressed the effect of blood pressure control on elderly hypertension patients in China. In response, this study aimed to investigate the prevalence and control of hypertension in the elderly population in Shanghai's communities.

METHODS

A secondary data analysis based on a government-financed health check-up program for an elderly population aged 65 and older from 2012 to 2014 was conducted in a central district of Shanghai.

RESULTS

Of the 44,978 study participants, 20,305 (45.1%) were males and 24,673 (54.9%) were females. The participants' median age was 72. Half of the participants were overweight or obese (BMI ≥ 24.0 kg/m2). The prevalence of hypertension was 59.9%. In the 18,032 participants without prior diagnosis of hypertension, 5530 (30.7%) had increased blood pressure. Among the 26,946 confirmed hypertension patients, the proportions of treatment and blood pressure control were 32.8% and 43.4% respectively. Multivariate analysis showed that the uncontrolled hypertension was significantly associated with older age, being overweight or obese, a lower level of education, an unbalanced dietary pattern, regular drinking and non-comorbidities.

CONCLUSIONS

The prevalence of hypertension was high in China's elderly population. The proportion of individuals who received treatment remained low, and blood pressure control was poor among hypertension patients. These results indicate that improvement of the ability to manage and control hypertension among urban elderly residents is urgently needed.
