Gender-specific prevalence and associated factors of hypertension among elderly Bangladeshi people: findings from a nationally representative cross-sectional survey.

ABSTRACT:

Objective

We aimed to estimate the gender-specific prevalence and associated factors of hypertension among elderly people in Bangladesh.

Design and method

We analysed data from the food security and nutrition surveillance round 2018-2019. The multistage cluster sampling method was used to select the study population. Hypertension was defined as systolic blood pressure ?140?mm?Hg and/or diastolic blood pressure ?90?mm?Hg and/or having a history of hypertension. We carried out the descriptive analysis, bivariate and multivariable logistic regression to report the weighted prevalence of hypertension as well as crude and adjusted ORs with 95% CI. A p value<0.05 was considered statistically significant.

Setting

The study was conducted in 82 clusters (57 rural, 15 non-slum urban and 10 slums) in all eight administrative divisions of Bangladesh.

Participants

A total of 2482 males and 2335 females aged ?60 years were included in this analysis.

Results

The weighted prevalence of hypertension was 42% and 56% among males and females, respectively. The prevalence was higher among females across all sociodemographic, behavioural and clinical strata. Factors associated with higher odds of hypertension (adjusted OR (AOR) (95% CI) for males and females, respectively) were age ?70 years (1.32 (1.09, 1.60) and 1.40 (1.15, 1.71)); insufficient physical activity (1.50 (1.25, 1.81) and 1.38 (1.15, 1.67)); higher waist circumference (2.76 (2.22, 3.43) and 2.20 (1.82, 2.67)); and self-reported diabetes (1.36 (1.02, 1.82) and 1.82 (1.35, 2.45)). Additionally, living in slums decreased (0.71 (0.52, 0.96)) and education >10 years increased odds of hypertension (1.83 (1.38, 2.44)) among males.

Conclusion

In Bangladesh, half of the elderly persons were hypertensive, with a higher prevalence in females. In both sexes, odds of hypertension was higher among persons with older age (?70 years), insufficient physical activity, higher waist circumference and self-reported diabetes. The Ministry of Health of Bangladesh should consider these findings while designing and implementing health programmes for elderly population.

Project description:BACKGROUND:Hypertension is a rapidly growing epidemic in China. Yet, it remains inadequately controlled, especially in rural areas. The internet has shown potential for better health management in different settings; however, few studies have investigated its role in hypertension management in China. OBJECTIVE:This study aims to examine the association between internet access and hypertension awareness, treatment, and control among elderly Chinese adults and to investigate whether the association between internet access and hypertension management differed between those living in urban and rural areas. METHODS:We obtained data from the nationally representative survey of the China Health and Retirement Longitudinal Study in 2011. Hypertension was defined as (1) average systolic blood pressure of ≥140 mm Hg or average diastolic blood pressure of ≥90 mm Hg or (2) currently taking antihypertensive medications. The outcome assessed included hypertension awareness, treatment, and control. The key independent variable was defined as whether one had internet access at home. We performed multivariate logistic regressions for each of the 3 outcomes. RESULTS:Among 5135 hypertensive respondents (age 62.4 [SD 9.9] years; 2351/5135, 45.78% men), 12.89% (662/5135) had internet access at home. Compared with those who had no internet access, internet access was positively associated with hypertension awareness (odds ratio [OR] 1.36, 95% CI 1.07-1.73) and treatment (OR 1.38, 95% CI 1.09-1.75), but not with control (OR 1.19, 95% CI 0.90-1.58). Internet access reduced urban-rural disparity in hypertension awareness by 9.6% (P=.02), treatment by 8.3% (P=.05), but not in control. In addition, the moderating effect of internet access on urban-rural disparities in hypertension management was larger among females. The decreased urban-rural disparities were primarily driven by that internet access improved the management level in rural areas. CONCLUSIONS:Despite the low rate of internet access among the elderly population, the internet shows its potential as a platform for achieving better hypertension management in China. Strategies for reducing the disparities in hypertension management and overall disease burden of hypertension among the elderly population might consider the internet as a platform.

Project description:BackgroundPrevalence of hypertension increases with age, but there is a general perception in India that women are less affected at every stage of life, although empiric evidence hardly exists regarding gender difference in hypertension in Indians of different ages. Therefore, we aimed to examine the gender difference in hypertension among Indians across various age-groups; and the contribution of variation in body mass index (BMI) to this difference.MethodsData were analysed after combining National Family Health Survey 4 (n = 294,584 aged 35-49 years) and Study of Ageing and Health wave 2 (n = 7118 aged 50 + years) datasets (NFHS-SAGE). Longitudinal Ageing Study of India (LASI) dataset (n = 65,900 aged > 45years) was analysed to replicate the results. Hypertension was defined if systolic and diastolic blood pressure was > 89 and/or > 139 respectively and/or if there was a history of anti-hypertensive medication. Descriptive summaries were tabulated and plotted to examine the gender difference in hypertension in various age-groups (35-39,40-44, 45-49, 50-54, 55-59, 60-64, 65-69, ≥ 70). Odds Ratios (ORs) from logistic regression models estimated the age gradient of hypertension and their male-female difference, adjusted for Body Mass Index (BMI).ResultsMales had a higher prevalence of hypertension up to 50 years; after that, females had higher rates. The estimates of age gradient, expressed as ORs, were 1.02 (1.02, 1.02) in males versus 1.05(1.05, 1.06) in females (p < 0.001) in NFHS-SAGE and 1.01(1.01, 1.02) in males versus 1.04(1.03, 1.04)in females (p < 0.001) in LASI;these differences marginally changed after adjustment with BMI.ConclusionThis is perhaps the first study to comprehensively demonstrate that cardio-metabolic risk in Indian females surpasses males after 50 years of age, "busting the myth" that Indian females are always at much lower risk than males; and this evidence should inform the Indian healthcare system to prioritise older women for screening and treatment of hypertension.

Project description:The World Health Organization (WHO) has recently developed a non-laboratory based cardiovascular disease (CVD) risk chart considering the parameters age, sex, current smoking status, systolic blood pressure, and body mass index. Using the chart, we estimated the 10-years CVD risk among the Bangladeshi population aged 40-74 years. We analyzed data from a nationally representative survey conducted in 2018-19. The survey enrolled participants from 82 clusters (57 rural, 15 non-slum urban, and 10 slums) selected by multistage cluster sampling. Using the non-laboratory-based CVD risk chart of the World Health Organization (WHO), we categorized the participants into 5 risk groups: very low (<5%), low (5% to <10%), moderate (10% to <20%), high (20% to <30%) and very high (> = 30%) risk. We performed descriptive analyses to report the distribution of CVD risk and carried out univariable and multivariable logistic regression to identify factors associated with elevated CVD risk (> = 10% CVD risk). Of the 7,381 participants, 46.0% were female. The median age (IQR) was 59.0 (48.0-64.7) years. Overall, the prevalence of very low, low, moderate, high, and very high CVD risk was 34.7%, 37.8%, 25.9%, 1.6%, and 0.1%, respectively. Elevated CVD risk (> = 10%) was associated with poor education, currently unmarried, insufficient physical inactivity, smokeless tobacco use, and self-reported diabetes in both sexes, higher household income, and higher sedentary time among males, and slum-dwelling and non-Muslim religions among females. One in every four Bangladeshi adults had elevated levels of CVD risk, and males are at higher risk of occurring CVD events. Non-laboratory-based risk prediction charts can be effectively used in low resource settings. The government of Bangladesh and other developing countries should train the primary health care workers on the use of WHO non-laboratory-based CVD risk charts, especially in settings where laboratory tests are not available.

Project description:ObjectivesThis study aimed to examine the distribution of daily salt intake across the hypertension care cascade and assess the proportional distribution of these care cascade categories across various salt consumption level.DesignA population-based national cross-sectional study.SettingsData from the Bangladesh STEPS 2018 survey were used, encompassing both urban and rural strata within all eight divisions. National estimates were generated from weighted data.ParticipantsA diverse population of 6754 men and women aged 18-69 years was included in the study.Outcome measuresDaily salt consumption was estimated using the spot urine sodium concentration following Tanaka equation. Distribution of salt intake among different categories of hypertension care cascade, including hypertensives, aware of hypertension status, on treatment and under control, was assessed.ResultsIndividuals with hypertension consume more salt on average (9.18 g/day, 95% CI 9.02 to 9.33) than those without hypertension (8.95 g/day, 95% CI 8.84 to 9.05) (p<0.02). No significant differences were found in salt intake when comparing aware versus unaware, treated versus untreated and controlled versus uncontrolled hypertension. In the overall population, 2.7% (95% CI 2.1% to 3.6%) of individuals without hypertension adhered to the recommended salt intake (<5 g/day) while 1.6% (95% CI 1.0% to 2.4%) with hypertension did so (p<0.03). Among individuals with hypertension, 2.4% (95% CI 1.4% to 4.0%) of those aware followed the guideline while only 0.8% (95% CI 0.4% to 1.9%) of those unaware adhered (p<0.03). Additionally, no significant differences were observed in adherence between the treated versus untreated and controlled versus uncontrolled hypertension.ConclusionsIndividuals with hypertension consume significantly more salt than those without, with no significant variations in salt intake based on aware, treated and controlled hypertension. Adhering to WHO salt intake guidelines aids better blood pressure management. By addressing salt consumption across hypertension care cascade, substantial progress can be made in better blood pressure control.

Project description:BackgroundGlobally, tobacco kills more than nine million people per year. Annually in Bangladesh, smoking accounts for 1.2 million illnesses and over one hundred fifty thousand deaths. Worldwide, about one out of five school students smoke tobacco, and this problem is also growing significantly in Bangladesh. There is a need to address this problem. However, to the best of knowledge, no published study has been evaluated the changes in factors associated with tobacco use over time among Bangladeshi adolescent students using large, nationally representative comparable surveys. Our objective was to identify the factors associated with tobacco use among school going students, examine any changes in them over time, and explore policy options based on national surveys.MethodsWe analysed the data from the 2007 and the 2013 Global Youth Tobacco Survey (GYTS), a school-based survey targeting adolescents age 13-15 years (7th-9th grade), developed by the World Health Organization (WHO) and the Centres for Disease Control and Prevention (CDC). The samples were selected based on a two-stage cluster sample design. The data were collected in school classes using a self-administered anonymous survey. We applied chi-square tests and survey logistic regression models for analysing the data.ResultsOverall tobacco usage significantly declined from 8.4 to 6.9% over six years. The prevalence of tobacco use decreased among females (5.22 to 2.84%), those who received anti-tobacco messages (8.93 to 7.24%) and because of age restriction could not buy tobacco products (18.86 to 15.78%). Compared with the female, the odds of overall tobacco smoking among male students was 1.97 (CI: 0.99-3.92) in the year 2007 and it increased (OR = 3.07; CI: 1.56-6.04) in the year 2013. Moreover, the odds of smoking among those exposed to tobacco smoke had increased (OR = 3.26; CI: 1.46-7.29 vs 5.43; CI: 1.63-18.07) from 2007 to 2013.ConclusionThere was a decline in tobacco use, especially among female students. Male students were higher tobacco user. It appeared anti-smoking campaign and age restriction policies were working.

Project description:BACKGROUND:Recent research suggests that mental health problems in spouses of cancer survivors are associated with worse mental health in the survivors themselves. Adequately treating spousal mental health problems therefore represents an opportunity to improve outcomes for both cancer survivors and their co-surviving family members. OBJECTIVE:Using nationally representative data, this study sought to determine how depression treatment differs between spouses of cancer survivors with depression compared to the general married population and assess rural/urban disparities in treatment. DESIGN:The design of the study is cross sectional. PARTICIPANTS:Data are from the Medical Expenditures Panel Survey, a household-based survey of US adults; we concatenated data from 2004 to 2013. We identified spouses of cancer survivors (n =?225) and a comparison group of married adults (n =?3678). MAIN MEASURES:Key measures included depression, guideline concordance of depression treatment (at least four prescriptions related to depression treatment, or at least eight psychotherapy or counseling visits), and sociodemographic characteristics. Logistic regressions evaluated the association between whether their spouse had cancer and receipt of guideline-concordant treatment, controlling for sociodemographic characteristics; secondary analyses included rurality as a moderator. Analyses were weighted to account for the complex sampling design. KEY RESULTS:Spouses of cancer survivors were 33% less likely to receive guideline-concordant depression treatment than comparison spouses (odds ratio (OR) 0.67, 95% confidence interval (CI) 0.45-0.99), controlling for covariates. Rural-urban disparities were observed: rural spouses of cancer survivors were 72% less likely to receive guideline-concordant treatment (OR 0.28, 95% CI 0.11-0.68) than rural comparison spouses. Spouses of cancer survivors and comparison spouses were no different in their receipt of any treatment versus no treatment. CONCLUSIONS:Spouses of cancer survivors with depression may be at increased risk of non-guideline-concordant depression treatment, particularly in rural areas. The findings have implications for identifying and educating individuals with depression in primary care and other clinical areas.
