RESUMO
Previous studies have shown that among Bangladeshi adults, one-fifth have hypertension. The National Heart Foundation of Bangladesh participated in May Measurement Month (MMM) campaigns in 2017, 2018, 2019, as well as in 2021 as a part of a global initiative aimed at raising awareness of high blood pressure (BP) and to act as a temporary solution to the lack of nationwide screening programmes. This opportunistic screening of voluntary participants aged ≥18 years was carried out from May to July 2021. Data were collected from more than 150 screening sites in all 64 districts in Bangladesh. Blood pressure measurement, the definition of hypertension, and statistical analysis followed the MMM protocol. Data on 28 355 individuals were finally analysed. Among the participants, 17 941 (63.3%) were female. After multiple imputation, 11 194 (39.5%) had hypertension. Among the 11 194 participants with hypertension, 78.8% were aware of having hypertension and 65.6% were on antihypertensive medication. Among 11 194 participants with hypertension, 7340 participants (65.6%) were on antihypertensive medication and 43.8% had controlled BP (<140/90â mmHg). Of those on antihypertensive medication, 66.8% had controlled BP. A voluntary BP screening programme can identify significant numbers of people with raised BP and thus contributes importantly to the prevention of cardiovascular diseases.
RESUMO
BACKGROUND: The World Health Organization (WHO) promotes the HEARTS technical package for improving hypertension control worldwide, but its effectiveness has not been rigorously evaluated. OBJECTIVE: To compare hypertension outcomes in clinics implementing HEARTS versus clinics continuing usual hypertension care in rural Bangladesh. METHODS: A matched-pair cluster quasi-experimental trial in Upazila Health Complexes (UHCs; primary healthcare facilities) was conducted in rural Bangladesh. A total of 3935 patients (mean age 52.3 years, 70.5% female) with uncontrolled hypertension (blood pressure (BP) ≥140/90 mm Hg regardless of treatment history) were enrolled: 1950 patients from 7 HEARTS UHCs and 1985 patients from 7 matched usual care UHCs. The primary outcome was systolic BP at 6 months measured at the patient's home; secondary outcomes were diastolic BP, hypertension control rate (<140/90 mm Hg) and loss to follow-up. Multivariable mixed-effects linear and Poisson models were conducted. RESULTS: Baseline mean systolic BP was 158.4 mm Hg in the intervention group and 158.8 mm Hg in the usual care group. At 6 months, 95.5% of participants completed follow-up. Compared with usual care, the intervention significantly lowered systolic BP (-23.7 mm Hg vs -20.0 mm Hg; net difference -3.7 mm Hg (95% CI -5.1 to -2.2)) and diastolic BP (-10.2 mm Hg vs -8.3 mm Hg; net difference -1.9 mm Hg (95% CI -2.7 to -1.1)) and improved hypertension control (62.0% vs 49.7%, net difference 12.3% (95% CI 9.0 to 16.8)). Rate of missed clinic visits was lower in the intervention group (8.8% vs 39.3%, p<0.001). CONCLUSIONS: After WHO-HEARTS package implementation in rural Bangladesh, BP was lowered and hypertension control improved significantly compared with usual care. TRIAL REGISTRATION NUMBER: NCT04992039.

OBJECTIVES: This 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. DESIGN: A population-based national cross-sectional study. SETTINGS: Data 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. PARTICIPANTS: A diverse population of 6754 men and women aged 18-69 years was included in the study. OUTCOME MEASURES: Daily 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. RESULTS: Individuals 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. CONCLUSIONS: Individuals 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.

BACKGROUND: Considering the health literacy status of service seekers is crucial while developing programs and policies to improve service delivery in primary health care settings. OBJECTIVE: Our aim was to assess health literacy among adults seeking non-communicable disease (NCD)-related services in primary health care centers (PHC) of Bangladesh and identify its contributing factors and its preventive effect on risky behaviors. METHODS: In this cross-sectional study, 2,793 NCD service seekers were interviewed face-to-face from eight rural and three urban PHCs selected by a multi-stage random sampling method. We used the European Health Literacy Survey Questionnaire to collect data on health literacy. We applied logistic regression analysis to identify the contributing factors related to adequate health literacy. Odds ratios were used to calculate the preventive fraction of health literacy for NCD risk behaviors. KEY RESULTS: Limited health literacy was found among 43% of the respondents. Adequate health literacy was associated with younger age, male sex, having a formal education, living in an extended family, hailing from a high socioeconomic group, and attending urban PHC. After adjusting the sociodemographic factors, the prevalence of smoking, smokeless tobacco usage, and inadequate fruits and vegetables consumption among participants were found to be 25%, 51%, and 18% lower for people with sufficient health literacy. CONCLUSIONS: NCD service seekers have a high rate of inadequate health literacy. Adequate health literacy has the potential to lower the behavioral risk factors of NCDs. [HLRP: Health Literacy Research and Practice. 2024;8(1):e12-e20.].
PLAIN LANGUAGE SUMMARY: This study is the first to address the knowledge gap regarding the state of NCD-related health literacy in Bangladesh. The findings of this study can be used by policymakers to create initiatives that will improve the health literacy of people seeking primary health care for NCDs.

The present study was undertaken to identify the major nutrient content in processed foods commonly consumed in Bangladesh, their label conformity healthiness, and percent daily nutrient contribution. Twenty-four nationally representative composite samples were analyzed using AOAC and other standard methods. Results were compared with label information using a restrictive approach and EU tolerance guidelines. The healthiness of the products was evaluated in terms of the Health Star Rating (HSR) scheme and the UK traffic light labeling system. Among the analyzed samples, fried pulse, chanachur, lozenge, and fried peas had the highest amount of protein, fat, carbohydrates, and dietary fiber, respectively. Biscuits and milk chocolate had high levels of trans fatty acids (TFA) and saturated fatty acids (SFA). It was observed that around half of the products lacked information about saturated fatty acid (46%), followed by total dietary fiber and trans-fat (38% each). Other information was missing in one-fifth of the products, namely protein (17%), total fat (17%), available carbohydrate (17%), energy (17%), sugar (21%), and salt (21%). Label compliance analysis according to the restrictive approach revealed that none of the products accurately reported the salt, sugar, saturated fat, and trans fat content on the label. According to the EU tolerance guideline, approximately half of the products had protein (58%), fat (54%), and carbohydrate (42%) levels that fell within the EU tolerance limit. However, only around one-third of the samples had sugar (21%), salt (38%), and saturated fat (33%) levels that met the EU tolerance limit. In terms of healthiness analysis, according to the HSR, the range of stars was between 0.5 and 2.5 of the foods where fried peas got the highest rating (2.5 stars), while in terms of the UK traffic light system, none of the samples got all green signals. The lozenge got green lights for fat, SFA, and salt contents. It was also found that consumption of 100 g of fried peas or pulse would exceed the acceptable daily limit of salt, sugar, and SFA compared to the daily maximum allowable intake for the 2000 kcal diet recommended by the WHO. However, according to the serving size, biscuits were major contributors of TFA, sugar, and SFA, whereas fried pulse was a key contributor of sodium/salt. Proper regulatory actions should be introduced to promote healthy processed foods with user-friendly front-of-the-pack labeling and monitor their quality to prevent non-communicable diseases (NCDs).
RESUMO
The World Health Organization recommended reducing one's salt intake below 5 g/day to prevent disability and death from cardiovascular and other chronic diseases. This review aimed to identify salt estimation at the population level in South Asian countries, namely Afghanistan, Bangladesh, Bhutan, India, Nepal, Pakistan, and Sri Lanka. We searched electronic databases and government websites for the literature and reports published between January 2011 and October 2021 and also consulted key informants for unpublished reports. We included studies that assessed salt intake from urinary sodium excretion, either spot urine or a 24 h urine sample, on a minimum of 100 samples in South Asian countries. We included 12 studies meeting the criteria after screening 2043 studies, out of which five followed nationally representative methods. This review revealed that salt intake in South Asian countries ranges from 6.7-13.3 g/day. The reported lowest level of salt intake was in Bangladesh and India, and the highest one was in Nepal. The estimated salt intake reported in the nationally representative studies were ranging from 8 g/day (in India) to 12.1 g/day (in Afghanistan). Salt consumption in men (8.9-12.5 g/day) was reported higher than in women (7.1-12.5 g/day). Despite the global target of population salt intake reduction, people in South Asian countries consume a much higher amount of salt than the WHO-recommended level.

OBJECTIVES: Left ventricular dysfunction and remodeling can occur as a result of aortic valve stenosis (AS). Three-dimensional speckle tracking echocardiography (3D-STE) can detect early left ventricular myocardial dysfunction even before ejection fraction declines. The purpose of this study was to look at the relationship between various myocardial strain parameters measured by 3D-STE in asymptomatic severe AS patients from Bangladesh. METHODS: This study included 46 patients with asymptomatic severe AS but preserved LV systolic function (mean age 50.11 ± 12.66 years, LVEF 63.78 ± 3.95%, AS group) and 33 healthy subjects with no cardiovascular disease (mean age 48.21 ± 4.53 years, LVEF 65.15 ± 3.13%, control group). 3D-STE was used to measure left ventricular global myocardial strain parameters such as peak systolic longitudinal strain (PSLS), circumferential strain, radial strain, and area strain. RESULTS: The AS group had significantly thicker interventricular septum and posterior ventricular wall than the control group (1.49 ± .19 cm vs. .81 ± .09 cm, p < .001; 1.73 ± 1.71 cm vs. .81 ± .10 cm, p = .003, respectively.) In the AS group, the Indexed Aortic Valve Area (AVA) was significantly lower than in the control group. (.29 ± .10 vs. 2.03 ± .18, p < .001, respectively). In terms of LVEF (p = .102), left ventricular end diastolic volume (p = .075), or left ventricular end systolic volume (p = .092), no significant inter-group difference was found. However, global PSLS (-10.75 ± 2.27 vs. -16.42 ± 2.76, p < .001), circumferential strain (-14.26 ± 3.40 vs. -16.64 ± 2.56, p = .001), area strain (-22.70 ± 4.19 vs. -26.45 ± 9.90, p = .024) and radial strain (32.20 ± 8.77 vs. 41.00 ± 7.52, p < .001) in the AS group were significantly lower than in the control group. CONCLUSION: Our findings showed reductions in left ventricular global myocardial strains, particularly PSLS in patients suffering from asymptomatic severe AS in Bangladesh; this is consistent with other studies. Reduced area strain, detectable with 3D-STE, is also consistent with that pattern.

OBJECTIVES: Team-based care is essential for improving hypertension outcomes in low-resource settings. We assessed perceptions of country representatives and healthcare workers (HCWs) on team-based hypertension care in low/middle-income countries. DESIGN: Two cross-sectional surveys. SETTING: The first survey (Country Profile Survey) was conducted in 17 countries and eight in-country regions: Algeria, Bangladesh, Burundi, Chile, China (Beijing, Henan, Shandong), Cuba, Ethiopia, India (Kerala, Madhya Pradesh, Maharashtra, Punjab, Telangana), Nepal, Nigeria, Philippines, Saint Lucia, Sri Lanka, Thailand, Turkey, Uganda and Vietnam. The second survey (HCW Survey) was conducted in four countries: Bangladesh, China, Ethiopia and Nigeria. PARTICIPANTS: Using convenience sampling, participants for the Country Profile Survey were representatives from 17 countries and eight in-country regions, and the HCW Survey was administered to HCWs in Bangladesh, China, Ethiopia and Nigeria. OUTCOME MEASURES: Country-level use of team-based hypertension care framework, comprising administrative, basic and advanced clinical tasks. Current practices of different HCW cadres, perspectives on team-based management of hypertension, barriers and facilitators. RESULTS: In the Country Profile Survey, all (23/23, 100%) countries/regions surveyed integrated team-based care for basic clinical hypertension management tasks, less for advanced tasks (7/23, 30%). In the HCW Survey, 854 HCWs participated, 47% of whom worked in rural settings. Most HCWs in the sample acknowledged the value of team-based hypertension care. Although there were slight variations by country in the study sample, overall, barriers to team-based hypertension care were identified as inadequate training (83%); regulatory issues (76%); resistance by patients (56%), physicians (42%) and nurses (40%). Facilitators identified were use of treatment algorithms (94%), telehealth/m-health technology (92%) and adequate compensation for HCWs (80%). CONCLUSIONS: Our findings revealed key lessons for health systems and governments regarding team-based care implementation. Specifically, policies to facilitate additional training, optimise HCWs' roles within care teams, use of hypertension treatment protocols and telehealth/m-health technology will be essential to promote team-based care.

BACKGROUND: In Bangladesh, the rapid rise of noncommunicable diseases (NCDs) has become a significant public health concern. This study assesses the readiness of hypertension (HTN)- and diabetes mellitus-related services at primary health-care facilities in Northeast Bangladesh. METHODOLOGY: A cross-sectional survey using a semi-structured interview was conducted between April 2021 and May 2021 among 51 public primary health-care facility staff (upazila health complexes [UHCs]). The NCD-specific service readiness was assessed using an adapted questionnaire from the WHO manual of Service Availability and Readiness Assessment and included four domains: guidelines and staff, basic equipment, diagnostic facility, and essential medicine. For each domain, the mean readiness index score was calculated. Facilities with a readiness score of above 70% were considered to be ready. RESULTS: The diagnostic capacity of the UHCs ranged from 0% to 88.9%, the availability of essential medicine and basic equipment varied between 15.4%-69.2% and 36.4%-100%, respectively, whereas the score in availability of basic amenities was between 57.1% and 100%. The score for the protocol drugs used to manage HTN was 52.9%, whereas for diabetes, it was 88.2%. The average general service readiness score for the facilities was 59.1%. Overall 17.6% of the facilities were assessed to be ready. CONCLUSION: Currently, primary health-care facilities are not ready to implement the national guidelines for diagnosing and treating diabetes and HTN due to shortages of medications, staff, and diagnostic materials.

OBJECTIVE: This study aimed to assess the validity of three commonly used (Tanaka, Kawasaki, INTERSALT) methods based on spot urinary sodium excretion against the 24-hour urinary sodium excretion to estimate the dietary salt intake in Bangladesh. DESIGN: A population-based cross-sectional survey. SETTING: A cross-sectional survey was done in an urban and a rural area of Bangladesh in 2012-2013. PARTICIPANTS: 418 community living residents aged 40-59 years participated in the survey and data of 227 subjects who had complete information were analysed for this validation study. OUTCOME MEASURES: The Bland-Altman method was used to evaluate the agreement between the estimated and measured 24-hour urinary sodium. The estimated average salt intake from Tanaka, Kawasaki and INTERSALT methods were plotted against 24-hour urinary sodium excretion. RESULTS: The mean 24-hour estimated salt intake was 10.0 g/day (95% CI 9.3 to 10.6). The mean estimated urinary salt by Tanaka, Kawasaki and INTERSALT methods were 8.5 g/day (95% CI 8.2 to 8.8), 11.4 g/day (95% CI 10.8 to 12.0) and 8.8 g/day (95% CI 8.6 to 9.0), respectively. Compared with the estimated mean salt intake from 24-hour urine collection, the Bland-Altman plot indicated the mean salt intake was overestimated by the Kawasaki method and underestimated by Tanaka and INTERSALT methods. The linear regression line showed the Kawasaki method was the least biased and had the highest intraclass correlation coefficient (0.57, 95% CI 0.45 to 0.67). CONCLUSION: Tanaka, Kawasaki and INTERSALT methods were not appropriate for the estimation of 24-hour urinary sodium excretion from spot urine samples to assess dietary salt intake in Bangladesh. Among the three methods, the Kawasaki method has the highest agreement with the 24-hour urinary sodium excretion concentration in this population.

OBJECTIVE: To estimate the costs of scaling up the HEARTS pilot project for hypertension management and risk-based cardiovascular disease (CVD) prevention at the full population level in the four subdistricts (upazilas) in Bangladesh. SETTINGS: Two intervention scenarios in subdistrict health complexes: hypertension management only, and risk-based integrated hypertension, diabetes, and cholesterol management. DESIGN: Data obtained during July-August 2020 from subdistrict health complexes on the cost of medications, diagnostic materials, staff salaries and other programme components. METHODS: Programme costs were assessed using the HEARTS costing tool, an Excel-based instrument to collect, track and evaluate the incremental annual costs of implementing the HEARTS programme from the health system perspective. PRIMARY AND SECONDARY OUTCOME MEASURES: Programme cost, provider time. RESULTS: The total annual cost for the hypertension control programme was estimated at US$3.2 million, equivalent to US$2.8 per capita or US$8.9 per eligible patient. The largest cost share (US$1.35 million; 43%) was attributed to the cost of medications, followed by the cost of provider time to administer treatment (38%). The total annual cost of the risk-based integrated management programme was projected at US$14.4 million, entailing US$12.9 per capita or US$40.2 per eligible patient. The estimated annual costs per patient treated with medications for hypertension, diabetes and cholesterol were US$18, US$29 and US$37, respectively. CONCLUSION: Expanding the HEARTS hypertension management and CVD prevention programme to provide services to the entire eligible population in the catchment area may face constraints in physician capacity. A task-sharing model involving shifting of select tasks from doctors to nurses and local community health workers would be essential for the eventual scale-up of primary care services to prevent CVD in Bangladesh.

This study explores the differences in factors associated with hypertension between younger and older subjects in an urban slum community in Bangladesh. We analyzed the data of 1,008 men and 1,001 women obtained from a cross-sectional survey conducted between October 2015 and April 2016. Multivariable logistic regression models were stratified by age (18 to 44 and 45 to 64 years) in men and women separately. The multivariable model included age (continuous) and the following categorical variables simultaneously: education duration, marital status, tobacco smoking, smokeless tobacco use, total physical activity, body mass index (BMI), waist circumference, and the blood levels of glycated hemoglobin (HbA1c), triglycerides, high- and low-density lipoprotein (HDL and LDL) cholesterol. Hypertension was defined as the presence of either blood pressure ≥140/90 mmHg or the use of antihypertensive medication. The prevalence of hypertension was 13.0% (younger men), 14.6% (younger women), 35.6% (older men), and 38.7% (older women). In younger men, higher waist circumference and increased LDL cholesterol levels were significantly associated with hypertension. In older men, physical activity was the only significant factor that was inversely associated with hypertension. In younger women, higher BMI, increased HbA1c, triglycerides, and LDL cholesterol levels were associated with hypertension. In older women, a higher HbA1c was the only factor significantly associated with hypertension. These findings suggest that public health interventions to prevent hypertension may require different approaches according to sex and age groups within the poor urban population in Bangladesh.

Background: In Bangladesh, there is a scarcity of nationally representative data on the burden of chronic obstructive pulmonary disease (COPD). Methods: To estimate the COPD prevalence in rural settings, this cross-sectional, population-based study was conducted in all eight administrative divisions of Bangladesh, and involved adults aged 40 years and above. By using multi-stage random sampling, 2,458 individuals were enrolled. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines were used to diagnose COPD based on post-bronchodilator lung function, while additional participant data was gathered through computer-assisted personal interviews. Results: A 2% COPD prevalence (95% CI: 1.45, 2.55) was found in the study sample with a statistically significant difference between males (2.7%; 95% CI: 1.8, 3.6) and females (1.2%; 95% CI: 0.59, 1.81). Increasing age significantly inflated the odds of having COPD irrespective of sex (OR: 1.03; 95% CI: 1.00, 1.05; P value < 0.05). Furthermore, prevalence of COPD was higher among manual workers, cigarette smokers, and those that used the indoor kitchen and did not have a primary education. Sex-based analysis showed that smokeless tobacco consumption was significantly associated with COPD occurrence among males (OR: 2.14; 95% CI: 1.05, 4.37; P value < 0.05), but not females. Further, using an indoor kitchen increased the odds of developing COPD by 400% among female participants (OR: 4.39; 95% CI: 1.37, 14.10; P value < 0.05). Conclusion: This study provides a comprehensive sex-based estimation of COPD prevalence among rural population and imparts significant contribution to the growing database on COPD prevalence in Bangladesh.
RESUMO
High dietary salt intake increases the risk of noncommunicable diseases (NCDs). NCDs are increasing among the urban poor in Bangladesh, but the data of their dietary salt intake are yet scarce. This study aimed to explore the amount of dietary salt intake among adults in an urban slum area in Dhaka, Bangladesh. A cross-sectional community-based study was conducted. We randomly selected 100 residents (39 men and 61 women) aged 20-59 years without history of NCDs. A modified World Health Organization standard instrument was used for behavioral risk factor assessment and physical measurements. Dietary salt intake was estimated from the measurement of sodium (Na) excretion in spot urine samples.The estimated mean dietary salt intake was 7.8 ± 2.5 g/day, and the mean Na/potassium (K) ratio in urine was 4.9 ± 3.4. More than half (54%) of them always took additional salt in their meals, but only 6% of them consumed 5 or more servings of fruits and vegetables per day. A quarter of them perceived salt reduction not at all important. Increased mean salt intakes were marginally associated with lower waist circumference and lower waist-hip ratio. Dietary salt intake among urban slum residents was higher than the recommended level of 5 g/day; however, its association with NCD risk factors was not significant. Further studies are required to identify the urban poor specific factors.

INTRODUCTION: Interventions aimed at promoting healthy eating habits in adolescence can help prevent chronic diseases and promote healthy ageing. The aim of this paper is to describe the fruit and vegetables consumption habits of adolescents in Dhaka, Bangladesh as well as to identify the socio-environmental, personal, and behavioral factors that influence these habits. MATERIALS AND METHODS: The baseline data from an intervention study involving 823 grade ten students from two randomly selected secondary schools in a semi-urban area of Dhaka were analyzed. The intake of fruit and vegetables was measured in terms of serving size per day. Hierarchical multiple regression was used to assess the ability of socio-environmental factors such as social support, perceived barriers, and living with patient with chronic diseases; personal factors such as knowledge, self-rated practice, behavioral intention, and body mass index; and behavioral factors such as physical activity, sedentary hours, and sleep duration to predict the level of daily fruit and vegetables intake, after controlling the effect of demographic characteristics of adolescents. RESULTS: The average daily consumption of fruit and vegetables was 1.22 and 1.99 servings, respectively. Only one-fifth of the respondents (21%) reported eating five servings of fruit and vegetables a day. Inaccessibility at home was reported as the most perceived barrier for both fruit and vegetables intake. Adolescents' higher fruit and vegetables intake was found to be associated with higher maternal educational attainment, more social support, adequate self-rated practice, positive behavioral intention, higher body mass index, better physical activity, and adequate daily sleeping. CONCLUSION: The findings revealed insufficient fruit and vegetables intake among adolescents in a semi-urban area of Bangladesh and associated socio-environmental, personal, and behavioral factors that were utilized in developing an intervention program for this transient age group. TRIAL REGISTRATION: Trial was registered at ClinicalTrials.gov (NCT03975335) https://clinicaltrials.gov/ct2/show/NCT03975335 on June 01, 2019.

According to the Non-communicable disease Risk Factors Survey of 2018, more than one-fifth (21.0%) of adults aged 25 years or older have hypertension and one-third of the adults did not have their blood pressure (BP) measured in their lifetime in Bangladesh. The National Heart Foundation of Bangladesh participated in May Measurement Month (MMM) 2017 and 2018 as well as this 2019 as a part of a global initiative aimed at raising awareness of high BP and to act as a temporary solution to the lack of screening programmes worldwide. This opportunistic screening of voluntary participants aged ≥18 years was carried out from May to July 2019. Data were collected from 100 screening sites in 16 districts in Bangladesh. BP measurement, the definition of hypertension, and statistical analysis followed the MMM protocol. Data on 24 941 individuals were analysed. Among the participants, 12 658 (50.8%) were female. After multiple imputation, 6990 (28.0%) had hypertension. Among the 6990 participants with hypertension, 5007 (71.6%) were on antihypertensive medication and 5331 (76.3%) were aware of having hypertension. Among 6990 participants with hypertension, 3217 (46.0%) had controlled BP (<140/90 mmHg) and among the participants with hypertension and on antihypertensive medication, 64.2% had controlled BP. Opportunistic BP screening can identify significant numbers of people with raised BP and thus assist in the prevention of cardiovascular diseases.
RESUMO
OBJECTIVE: We implemented this study to report the prevalence and associated risk factors of hypertension among adult men and women aged >30 years residing in selected urban and rural areas of Dhaka division, Bangladesh. DESIGN: Cross-sectional study. SETTING: Two urban (Dhaka city north and Dhaka city south) and two rural (Narsinghdi and Gazipur district) areas of the Dhaka division. PARTICIPANTS: A total of 4856 male and female participants were included in the final analysis, of whom 2340 (48.2%) were from urban and 2516 (51.8%) were from rural areas. PRIMARY OUTCOME: Hypertension was the dependent variable for this study and was operationally defined as systolic blood pressure >140 mm of Hg and/or diastolic blood pressure >90 mm of Hg, and/or persons with already diagnosed hypertension. RESULTS: The overall prevalence of hypertension was 31.0%, and the prevalence was higher among urban participants (urban: 36.9%, rural: 30.6%). Age (across all categories), female (urban-adjusted OR (AOR): 1.3, 95% CI: 1.0 to 1.5 and rural-AOR: 1.7, 95% CI: 1.4 to 2.1)), higher educational status (urban-AOR: 1.7, 95% CI: 1.3 to 2.2 and rural-AOR: 2.1, 95% CI: 1.5 to 3.1), inadequate physical activity (urban-AOR: 1.3, 95% CI: 1.0 to 1.7 and rural-AOR: 1.5, 95% CI: 1.2 to 1.9) and overweight/obesity (urban-AOR: 2.7, 95% CI: 2.1 to 3.3 and rural-AOR: 2.1, 95% CI: 1.7 to 2.5) were associated with hypertension in both urban and rural areas. Women who were not currently married during the survey had higher odds of hypertension only in the rural areas (rural-AOR: 1.8, 95% CI: 1.3 to 2.4), and respondents who were not working during the survey had higher odds of hypertension only in the urban areas (AOR: 1.7, 95% CI: 1.0 to 2.6). CONCLUSION: Since the prevalence of hypertension was high in urban and rural areas, the government of Bangladesh should consider implementing hypertension prevention programmes focusing young population of Dhaka division. In addition, early screening programmes and management of hypertension need to be strengthened for people with hypertension in both the areas.

OBJECTIVE: Prevention of mortality due to cardiovascular disease (CVD) through control of hypertension is a public health priority in Bangladesh. Our objective was to assess sex differences in prevalence and determinants of hypertension among adults in one rural area of Bangladesh. STUDY DESIGN: Cross-sectional. SETTING AND PARTICIPANTS: From January 2014 to December 2015, we conducted a cross-sectional study of 2600 men and women aged ≥18 years located in one rural district of Bangladesh. We collected data on demographics, behavioural factors, physical measurements and health history. PRIMARY OUTCOME MEASURES: Our primary outcome was hypertension (systolic blood pressure ≥140 or diastolic blood pressure ≥90 mm Hg). RESULTS: The average age of participants was 41.6 years and 53.7% were women. Hypertension prevalence was 6.9% (95% CI 5.9 to 7.9), and was significantly higher among women (8.9%) than men (4.5%). The highest prevalence of hypertension was observed among women aged ≥60 years at 21.3% (95% CI 16.6 to 26.7). A higher proportion of men with hypertension were aware of their condition (72.2%) compared with women (52.4%). Determinants of hypertension included older age, higher education, current tobacco use, increasing body mass index, and hyperglycaemia. CONCLUSION: Our research suggests that hypertension prevalence is higher among women than men in rural Bangladesh. Sex-specific interventions should be developed to inform adults of the necessary lifestyle changes that may reduce the risk of hypertension and subsequent CVDs.

Elevated blood pressure (BP) is a growing burden worldwide, leading to over 10 million deaths each year. According to Non-communicable disease (NCD) Risk Factors Survey Bangladesh 2010, one-fifth (21.9%) of adults aged 25 years or more have hypertension. Almost one-third of the adult population did not have their BP measured in their lifetime in Bangladesh. National Heart Foundation of Bangladesh participated in May Measurement Month (MMM) 2018 as a part of a global initiative aimed at raising awareness of high BP and to act as a temporary solution to the lack of screening programmes nationally. An opportunistic cross-sectional survey of volunteers aged ≥18 years was carried out in May 2018. Blood pressure measurement, the definition of hypertension and statistical analysis followed the MMM protocol. Data were collected from 10 screening sites in 9 districts in Bangladesh. A total of 5208 individuals were screened during MMM18. After multiple imputation, 1750 (33.6%) had hypertension. Among the 1750 participants with hypertension, 1312 (75.0%) were aware of having hypertension. Among those that were not on antihypertensive medication, 15.2% were hypertensive and among those that were on antihypertensive medication 33.6% had uncontrolled hypertension. The present study showed that opportunistic screening can identify significant numbers of people with raised BP. A periodic public health programme at a national level needs to be initiated to increase hypertension detection and control rates and thus for prevention of cardiovascular diseases.
RESUMO
In low and middle-income countries (LMICs), strict social distancing measures (e.g., nationwide lockdown) in response to the COVID-19 pandemic are unsustainable in the long-term due to knock-on socioeconomic and psychological effects. However, an optimal epidemiology-focused strategy for 'safe-reopening' (i.e., balancing between the economic and health consequences) remain unclear, particularly given the suboptimal disease surveillance and diagnostic infrastructure in these settings. As the lockdown is now being relaxed in many LMICs, in this paper, we have (1) conducted an epidemiology-based "options appraisal" of various available non-pharmacological intervention options that can be employed to safely lift the lockdowns (namely, sustained mitigation, zonal lockdown and rolling lockdown strategies), and (2) propose suitable application, pre-requisites, and inherent limitations for each measure. Among these, a sustained mitigation-only approach (adopted in many high-income countries) may not be feasible in most LMIC settings given the absence of nationwide population surveillance, generalised testing, contact tracing and critical care infrastructure needed to tackle the likely resurgence of infections. By contrast, zonal or local lockdowns may be suitable for some countries where systematic identification of new outbreak clusters in real-time would be feasible. This requires a generalised testing and surveillance structure, and a well-thought out (and executed) zone management plan. Finally, an intermittent, rolling lockdown strategy has recently been suggested by the World Health Organization as a potential strategy to get the epidemic under control in some LMI settings, where generalised mitigation and zonal containment is unfeasible. This strategy, however, needs to be carefully considered for economic costs and necessary supply chain reforms. In conclusion, while we propose three community-based, non-pharmacological options for LMICs, a suitable measure should be context-specific and based on: (1) epidemiological considerations, (2) social and economic costs, (3) existing health systems capabilities and (4) future-proof plans to implement and sustain the strategy.
