Acceptability and Feasibility of a Tai Chi/Qigong Intervention for Older People Living With HIV.

Tai chi/qigong (TCQ) is a low impact, meditative movement with breathwork that may benefit people with HIV (PWH) over 50 years old. This study is a feasibility clinical trial of a remote TCQ intervention for older PWH. Participants (n = 48) were recruited via clinic sites and social media and randomized to a TCQ, sham qigong, or wait-list control group. The 12-week intervention included fourteen 45-60-minute sessions. Acceptability (satisfaction, attitudes, practice, attendance) and feasibility (retention rate, adverse events, remote delivery) data were surveyed. Overall retention rate was 72.9%, but 81.2% for the TCQ group. Most TCQ participants attended at least 10 sessions (62.5%) and were practicing TCQ after 2 weeks (72.7%). Over 92% of TCQ participants reported satisfaction and positive attitudes and preferred remote versus in person delivery (63.6%). Two mild intervention related adverse events occurred. Findings suggest that a remote TCQ intervention is acceptable, feasible, and safe among older PWH.

RESUMEN: Tai chi/qigong (TCQ) es un movimiento meditativo de bajo impacto con ejercicios de respiración que puede beneficiar personas que viven con VIH (PVV) mayores de 50 años. Este estudio es un ensayo clínico de viabilidad que evalúa una intervención de TCQ administrada remotamente para personas mayores que viven con VIH. Participaron personas (n = 48) reclutadas en clínicas y redes sociales, asignadas aleatoriamente a un grupo de TCQ, qigong falso, o control en lista de espera. La intervención duró 12 semanas con catorce sesiones de 45 a 60 minutos. Se encuestaron datos sobre aceptabilidad (satisfacción, actitudes, práctica, asistencia) y viabilidad (retención, eventos adversos, entrega remota). La tasa de retención general fue del 72,9%, pero del 81,2% para el grupo de TCQ. La mayoría de los participantes de TCQ asistieron a al menos 10 sesiones (62,5%) y continuaron practicando después de 2 semanas (72,7%). La satisfacción y las actitudes positivas hacia la intervención fueron reportadas por más del 92% de los participantes de TCQ quienes prefirieron la participación remota contra clases en persona (63,6%). Dos eventos adversos leves relacionados con la intervención ocurrieron. Los resultados sugieren que una intervención de TCQ administrada de forma remota es aceptable, viable y seguro para personas mayores que viven con VIH.

Comorbidities among persons living with HIV (PLWH) in Florida: a network analysis.

People living with HIV (PLWH) experience a higher rate of age-related comorbidities at younger ages. Understanding common comorbidities among PLWH and their relationship to one another could be significant in improving aging for PLWH. The goal of the present study is to identify the most common comorbidities among PLWH and the relationship between them using network analysis. We used abstracted electronic medical record (EMR) data of PLWH from the Florida Cohort study, a prospective cohort study conducted in eight cities in Florida, USA. We used International Classification of Diseases (10th revision, ICD-10) code to classify comorbidities and organ systems. Network analysis was conducted to determine the degree and betweenness centrality among comorbidities. We included 756 PLWH with an average age of 46.4 years (SD 11.3) in the analysis. Infectious diseases (A00-B99, 50.8%), mental and behavioural (F01-F99, 47.0%), endocrine, nutritional and metabolic (E00-E88, 45.2%), and circulatory (I00-I99, 39%) disorders were the most prevalent system comorbidities among PLWH. Hypertensive disorder (I10-I1635.8%), dyslipidaemia (E78, 25.7%) and major depressive disorder (F32-F33, 23.9%) were the most common non-infectious conditions affecting PLWH. Viral hepatitis (B15-B19, 17.1%) and syphilis (A15-A53, 12%) were the most common coinfections among PLWH. Hypertension, dyslipidaemia and major depressive disorder were the most central of the comorbidities among PLWH. Comorbidities among PLWH were most prevalent for chronic disease and mental illness. Targeting shared disease risk factors in addition to monitoring known pathological pathways may prevent comorbidities among PLWH.

Personal exposure to household air pollution and lung function in rural Bangladesh: A population-based cross-sectional study.

We assessed whether personal exposure to household air pollution [PM2.5 and black carbon (BC)] is associated with lung functions (FEV1, FVC, and their ratio) in non-smoking adults in rural Bangladesh. We measured personal exposure to PM2.5 using gravimetric analysis of PM2.5 mass and BC by reflectance measurement between April 2016 and June 2019. The average 24-hour PM2.5 and BC concentration was 141.0µgm-3 and 13.8µgm-3 for females, and 91.7 µgm-3 and 10.1 µgm-3 for males, respectively. A 1 µgm-3 increase in PM2.5 resulted in a 0.02 ml reduction in FEV1, 0.43 ml reduction in FVC, and 0.004% reduction in FEV1/FVC. We also found a similar inverse relationship between BC and lung functions (9.6 ml decrease in FEV1 and 18.5 ml decrease in FVC per 1µgm-3 increase in BC). A higher proportion of non-smoking biomass fuel users (50.1% of the females and 46.7% of the males) had restrictive patterns of lung function abnormalities, which need further exploration.

Household biomass fuel use is associated with chronic childhood malnutrition: Result from a nationwide cross-sectional survey in Bangladesh.

Despite significant investment, childhood malnutrition continues to be a significant public health problem especially in least developed countries. The aim of this study was to find association between household biomass fuel (BMF) use and childhood malnutrition in Bangladesh using data from Demographic and Health Survey 2011. We included a total 6891 children under 5 years of age in the analysis. The prevalence of wasting, underweight, and stunting from BMF using household was 16.1% (n = 997; 95%CI, 15.1-17.3), 39.0% (n = 2399; 95%CI, 37.1-40.9), and 43.3% (n = 2620; 95%CI, 41.6-45.1), respectively. Underweight and stunting were significantly higher among children from households using BMF compared with the children from CF using households (underweight, biomass vs clean fuel: 39.0% vs. 23.5%, p < 0.001; stunting, biomass vs clean fuel: 43.3 vs. 31.5%, p < 0.001). The use of BMF in the household was significantly associated with underweight (OR = 1.38; 95%CI: 1.10-1.73) and stunting (OR = 1.58; 95%CI: 1.18-1.98) among children <5 years of age after adjusting possible confounders in mixed effect logistic regression analysis. This study found a significant association between chronic childhood malnutrition and household BMF use which is indicating possible alternative risk factor for malnutrition. Further prospective research is required to explore the mechanism of how BMF use results in chronic malnutrition.

Evaluating medicine prices, availability and affordability in Bangladesh using World Health Organisation and Health Action International methodology.

BACKGROUND: Previous studies have shown limited availability of medicines in health facilities in Bangladesh. While medicines are dispensed for free in public facilities, they are paid out-of-pocket in private pharmacies. Availability, price and affordability are key concerns for access to medicines in Bangladesh. METHODS: The World Health Organization/Health Action International survey methodology was used to determine price, availability and affordability of 61 lowest price generic (LPG) and originator branded medicines in public facilities, private retail pharmacies and private clinics across 6 regions of Bangladesh. Medicines for non-communicable and infectious diseases, and both on and off the national Essential Medicines List were included. Prices were compared internationally using Median Price Ratio (MPR). RESULTS: Mean LPG (originator brand) availability in the public sector, private retail pharmacies, and private clinics was 37%, 63 (4) percent, and 54 (2) percent, respectively. Medicines for Non-Communicable Diseases (NCD) and essential medicines were significantly less available than infectious disease medicines and non-essential medicines, respectively. Mean LPG (originator brand) MPR was 0.977 in the public sector, 1.700 (3.698) in private retail pharmacies and 1.740 (3.758) in private clinics. Six medicines were expensive by international standards across all sectors. The least affordable treatments in both private sectors were bisoprolol (hypertension), metformin (diabetes) and atorvastatin (hypercholesterolemia). CONCLUSION: Availability and affordability of NCD medicines are key concerns where the burden of NCD is rising. These findings show improvement from earlier studies, but room for further advances in availability and affordability of NCD medicines in Bangladesh. A small number of medicines are consistently expensive across sectors in Bangladesh, suggesting the need for strategies to address prices for certain medicines.

Access to primary health care for acute vascular events in rural low income settings: a mixed methods study.

BACKGROUND: Cardiovascular diseases (CVDs) are the leading cause of global mortality. Among the CVDs, acute vascular events (AVE) mainly ischemic heart diseases and stroke are the largest contributors. To achieve 25% reduction in preventable deaths from CVDs by 2025, health systems need to be equipped with extended service coverage in order to provide person-centered care. The overall goal of this proposed study is to assess access to health care in-terms of service availability, care seeking patterns and barriers to access care after AVE in rural Bangladesh. We will consider myocardial infarction (MI) and stroke as acute vascular events. METHODS/DESIGN: We will conduct a mixed methods study in rural Matlab, Bangladesh. This study will comprise of a) health facility survey, b) structured questionnaire interview and c) qualitative study. We will assess service availabilities by creating an inventory of public and private health facilities. Readiness of the facilities to deliver services for AVE will be assessed through a health facility survey using 'service availability and readiness assessment' (SARA) tools of the World Health Organization (WHO). We will interview survivors of AVE and caregivers (present and accompanied the person during the event) of person who died from AVE for exploring patterns of care seeking during an AVE. For exploring barriers to access care for AVE, we will conduct in-depth interview with survivors of AVE and caregivers of the person who died from AVE. We will also conduct key informant interviews with the service providers at primary health care (PHC) facilities and government high level officials at central health administration of Bangladesh. DISCUSSION: This study will provide a comprehensive picture of access to primary health care services during acute cardiovascular events as stroke & MI in rural context of Bangladesh. It will explore available service facilities in rural area for management, utilization of services and barriers to access care during an acute emergency. This study will help to generate hypothesis, develop programs and policies for better access to care for AVE in similar rural settings considering barriers of access and improving utilization.

Prevalence and Determinants of Chronic Obstructive Pulmonary Disease (COPD) in Bangladesh.

RATIONALE: There is a paucity of population-based data on COPD prevalence and its determinants in Bangladesh. OBJECTIVE: To measure COPD prevalence and socioeconomic and lifestyle determinants among ≥40 years Bangladeshi adults. METHODS: In a cross-sectional study, we measured lung function of 3744 randomly selected adults ≥40 years from rural and urban areas in Bangladesh, using a handheld spirometer. COPD was defined according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria as post-bronchodilator ratio of Forced Expiratory Volume in 1st second (FEV1) to Forced Vital Capacity (FVC) < 0.7. In addition, COPD was also assessed by the lower limit of normal (LLN) threshold defined as lower fifth percentile for the predicted FEV1/FVC. RESULTS: The prevalence of COPD was 13.5% by GOLD criteria and 10.3% by LLN criteria. Prevalence of COPD was higher among rural than urban residents and in males than females. More than half of the COPD cases were stage II COPD by both criteria. Milder cases (Stages I and II) were over estimated by the GOLD fixed criteria, but more severe cases (Stages III and IV) were similarly classified. In multiple logistic regression analysis, older age, male sex, illiteracy, underweight, history of smoking (both current and former), history of asthma and solid fuel use were significant predictors of COPD. CONCLUSION: COPD is a highly prevalent and grossly underdiagnosed public health problem in Bangladeshi adults aged 40 years or older. Illiteracy, smoking and biomass fuel burning are modifiable determinants of COPD.

Patterns of common illness and injury of readymade garment workers and a review of safety practices in Bangladesh.

BACKGROUND: Readymade garment workers globally experience distinctive vulnerabilities at the workplace. The situation is worse in many developing countries. However, there is a lack of scientific evidence about the health and safety of garment workers in the workplace. OBJECTIVE: The objective of this study was to examine the patterns of illness and injury of garment workers, factory level health safety policies and programs, and views and perception of management staff at factories in Bangladesh. METHODS: This mixed-method study was conducted among garment workers and management level staff between January 2018 and April 2019. We extracted 4000 health records of the workers who attended primary health care centers of the factories and conducted 11 key informant interviews using qualitative method from different management-level staff. RESULTS: Half of the workers (51.0%) were working in the sewing section following 12.8% in quality control and 12.3% in the laundry section. A review of the medical records showed that peptic ulcer diseases (PUDs) (19.2%), fever (11.7%), loose motion (10.3%), and headache (9.4%). Needle injury was uncommon for taking medical care. Occupational safety and health management, safe drinking water, access to maternity leave and other facilities were better in large and medium factories compared with those in small factories. CONCLUSIONS: Although the readymade garments sector is one of the largest sources of foreign currency revenue earnings in Bangladesh, occupational health and safety issues of workers remain a big concern. Thus, support from the government needs more focus on the health and safety of workers.

Smoking-attributable mortality in Bangladesh: proportional mortality study.

OBJECTIVE: To directly estimate how much smoking contributes to cause-specific mortality in Bangladesh. METHODS: A case-control study was conducted with surveillance data from Matlab, a rural subdistrict. Cases (n = 2213) and controls (n = 261) were men aged 25 to 69 years who had died between 2003 and 2010 from smoking-related and non-smoking-related causes, respectively. Cause-specific odds ratios (ORs) were calculated for "ever-smokers" versus "never-smokers", with adjustment for education, tobacco chewing status and age. Smoking-attributable deaths among cases, national attributable fractions and cumulative probability of surviving from 25 to 69 years of age among ever-smokers and never-smokers were also calculated. FINDINGS: The fraction of ever-smokers was about 84% among cases and 73% among controls (OR: 1.7; 99% confidence interval, CI: 1.1-2.5). ORs were highest for cancers and lower for respiratory, vascular and other diseases. A dose-response relationship was noted between age at smoking initiation and daily number of cigarettes or bidis smoked and the risk of death. Among 25-year-old Bangladeshi men, 32% of ever-smokers will die before reaching 70 years of age, compared with 19% of never-smokers. In 2010, about 25% of all deaths observed in Bangladeshi men aged 25 to 69 years (i.e. 42,000 deaths) were attributable to smoking. CONCLUSION: Smoking causes about 25% of all deaths in Bangladeshi men aged 25 to 69 years and an average loss of seven years of life per smoker. Without a substantial increase in smoking cessation rates, which are low among Bangladeshi men, smoking-attributable deaths in Bangladesh are likely to increase.

Effect of exposure to maternal diabetes during pregnancy on offspring's brain cortical thickness and neurocognitive functioning.

Little is known about the long-term effects of maternal diabetes during pregnancy (DP), either gestational diabetes or preexisting diabetes (type 1 or type 2), on offspring's brain morphometry and neurocognitive functioning (NCF). This study examined the effect of prenatal exposure to maternal DP on the brain structure and NCF in children between 9 and 10 years of age. This study used cross-sectional neuroimaging and NCF data from the baseline wave of the Adolescent Brain and Cognitive Development® study. Exposure to maternal DP was assigned from the developmental history questionnaire. Differences in the brain cortical thickness (CTh) and five cognitive abilities (executive function, working and episodic memory, processing speed, and language abilities) were examined in diabetes-exposed and diabetes-unexposed children. Linear mixed effect models and generalized linear models were used to adjust for the effect of confounding variables. A total of 9,967 children (718 diabetes-exposed and 9249 unexposed) were included in the analysis. Diabetes-exposed children had lower whole-brain CTh [mean: exposed vs unexposed = 2.725 mm vs 2.732 mm; difference (95%CI): -0.007 mm (-0.013, -0.001)] compared to unexposed children after adjusting for confounding variables. Diabetes-exposed children had lower CTh in most part of the occipital lobe of both hemispheres, right postcentral gyrus, and left superior parietal cortex. Diabetes-exposed children also had lower scores in processing speed task [mean difference (95%CI): -1.7 (-2.8, -0.6)] and total cognition [mean difference (95%CI): -0.6 (-1.2, -0.02)]. Diabetes-exposed children have reduced CTh and NCF during preadolescence, which might have implications for psychomotor development during later life. Prospective studies are needed to confirm our findings.

Disparities in Compliance with Colorectal Cancer Screening: Evidence from Two US National Surveys.

OBJECTIVE: Colorectal cancer (CRC) is the most preventable cancer if adherence to its screening guidelines through compliance with physician recommendations are met. Lack of access to care is the most significant barrier which was decreased by the Affordable Care Act (ACA), that may influence healthcare behaviors/practices. The aim of this study was to determine the factors affecting compliance with recommendations for CRC screening between two US National Health Interview Surveys (NHIS) in 2010 and 2015. METHODS: We used individual data of adults aged ≥50 years from the Cancer Module of NHIS that repeats every-5-years. Multiple logistic regression analyses were employed to identify the compliance associated factors and their changes after five years. RESULTS: We included final data of 1,553 and 2259 and individual from 2010 and 2015, respectively. Overall, compliance to physician recommendations for colorectal cancer was 85.70% in 2010 and 81.54%. Men compiled more in 2010 than women which was reversed in 2015. The multivariable-adjusted odds of compliance were increased with age; lower for female [Odds ratio (OR)= 0.45 Confidence Interval (CI 95% 0.27, 0.75), having a family history of CRC [OR=3.05 CI:1.02, 9.05], having insurance [OR 3.58 CI:1.4, 9.12], and Odds increased with the number of doctor visit in 2010. However, in 2015 the odds were substantially increased with the increasing age, reversed odds for female [OR= 3.49 CI: 1.67, 7.29)], increased for non-Hispanic Blacks [OR= 4.87 CI: 2.05, 11.55] and lower for Asian [OR=0.33 CI:0.15, 0.74], higher for family history of colorectal cancer [OR=3.31 CI:1.92, 5.69]. Although insurance coverage and the number of doctor visits were significant predictors of compliance in 2010, those became non-significant in 2015. CONCLUSIONS: Compliance disparities by gender and access to healthcare either reduced in strength or reversed between 2010 and 2015. The non-Hispanic Black significantly higher in compliance than other race-ethnicities in 2015.

Effect of maternal hypertensive disorder on their children's neurocognitive functioning in mediated via low birthweight and BMI not by brain cortical thickness.

The aim of the study was to examine the association between prenatal exposure to maternal Hypertensive disorder during pregnancy (HDP) on brain structure and neurocognitive functioning (NCF) in singleton children aged between 9 and 10 years using the baseline wave of the Adolescent Brain and Cognitive Development (ABCD) Study. The ABCD Study® interviewed each child (and their parents), measured NCF, and performed neuroimaging. Exposure to maternal high blood pressure (HBP) and preeclampsia or eclampsia (PE/EL) were extracted from the developmental history questionnaire. Differences in cortical thickness (CTh) and five cognitive abilities (two executive functions, working and episodic memory, processing speed, and two language abilities) between exposed and unexposed children were examined using generalized linear models. The mediating effects of CTh, birthweight, and BMI on the relationship between maternal HDP on NCF were also examined. A total of 584-children exposed to HBP, 387-children exposed to PE/EL, and 5,877 unexposed children were included in the analysis. Neither CTh nor NCF differed between the exposed and unexposed children with or without adjusting for the confounders including the child's age, sex, race, education, and birth histories. The whole-brain CTh did not mediate the relationships between HDP and NCF. However, the relationship between HDP and most of the NCF was mediated by the child's birthweight and BMI. Exposure to maternal HDP can affect their offspring's later-life cognitive abilities via low birthweight and BMI during childhood. Prospective longitudinal studies, following up from infancy, are needed to further delineate the association of HDP on children's cognitive abilities.

Reduction of household air pollution through clean fuel intervention and recovery of cellular immune balance.

BACKGROUND: We conducted a clean fuel intervention trial (Bangladesh Global Environmental and Occupational Health (GEOHealth) (NCT02824237) with liquefied petroleum gas (LPG) for 26 months among rural Bangladeshi women chronically exposed to household air pollution (HAP) from biomass fuel (BMF) use. We aimed to evaluate the effect of HAP reduction following LPG intervention on immune response outcome. METHODS: We supplied LPG cook stove and refills in cylinder in 200 households for 26 months. We measured personal exposure to HAP [particulate matter 2.5 (PM2·5), black carbon (BC) and carbon monoxide (CO)] in 200 women (main cook) by personal monitors at pre- and post-intervention. Immune function was assessed before and after intervention, in blood collected within 2 weeks of HAP measurements. Primary endpoints included reduction in HAP, lymphocyte proliferation and oxidative stress response, and alterations in T and B cell proportions. FINDINGS: Exclusive LPG use for 26 months resulted in significant reduction in PM2·5 (43.5%), BC (13%) and CO (48%) exposure in the women. For one unit decrease in BC, Treg cells and memory B cells increased by 7% and 34% respectively, in the peripheral circulation. One unit decrease in CO was significantly associated with increase in early B cells and plasmablasts by 66% and 5% respectively. For one unit decrease in BC, percent-dividing cells, proliferation and expansion indices increased by 2%, 0.4%, and 1%, respectively. INTERPRETATION: Reduced personal exposure to HAP through clean fuel intervention was related to a return towards cellular immune balance.

Acculturation gap conflicts and self-rated health among Hispanic emerging adults.

INTRODUCTION: Emerging adulthood is a distinct and challenging developmental stage of life. It may be particularly stressful for Hispanic emerging adults due to various cultural stressors. However, there is little research on the impact of one particular cultural stressor, the acculturation gap. Therefore, this study aims to examine whether acculturation gap conflicts are associated with self-rated health. METHOD: Participants were recruited in Arizona and Florida, and 200 Hispanic emerging adults (ages 18-25) completed a cross-sectional survey. Data were analyzed using hierarchical multiple regression. RESULTS: Coefficients from a hierarchical multiple regression model indicated that higher levels of acculturation gap conflicts were associated with lower self-rated health after controlling for psychological stress and other demographic variables. DISCUSSION: This is the first study on acculturation gap conflicts and self-rated health among Hispanics. Findings from this study indicate that acculturation gap conflicts are associated with self-rated health and merit further investigation as they may have implications for health interventions targeting Hispanics.

Association of household air pollution with cellular and humoral immune responses among women in rural Bangladesh.

Household air pollution (HAP) arising from combustion of biomass fuel (BMF) is a leading cause of morbidity and mortality in low-income countries. Air pollution may stimulate pro-inflammatory responses by activating diverse immune cells and cyto/chemokine expression, thereby contributing to diseases. We aimed to study cellular immune responses among women chronically exposed to HAP through use of BMF for domestic cooking. Among 200 healthy, non-smoking women in rural Bangladesh, we assessed exposure to HAP by measuring particulate matter 2.5 (PM2.5), black carbon (BC) and carbon monoxide (CO), through use of personal monitors RTI MicroPEM™ and Lascar CO logger respectively, for 48 h. Blood samples were collected following HAP exposure assessment and were analyzed for immunoprofiling by flow cytometry, plasma IgE by immunoassay analyzer and cyto/chemokine response from monocyte-derived-macrophages (MDM) and -dendritic cells (MDDC) by multiplex immunoassay. In multivariate linear regression model, a doubling of PM2.5 was associated with small increments in immature/early B cells (CD19+CD38+) and plasmablasts (CD19+CD38+CD27+). In contrast, a doubling of CO was associated with 1.20% reduction in CD19+ B lymphocytes (95% confidence interval (CI) = -2.36, -0.01). A doubling of PM2.5 and BC each was associated with 3.12% (95%CI = -5.85, -0.38) and 4.07% (95%CI = -7.96, -0.17) decrements in memory B cells (CD19+CD27+), respectively. Exposure to CO was associated with increased plasma IgE levels (beta(ß) = 240.4, 95%CI = 3.06, 477.8). PM2.5 and CO exposure was associated with increased MDM production of CXCL10 (ß = 12287, 95%CI = 1038, 23536) and CCL5 (ß = 835.7, 95%CI = 95.5, 1576), respectively. Conversely, BC exposure was associated with reduction in MDDC-produced CCL5 (ß = -3583, 95%CI = -6358, -807.8) and TNF-α (ß = -15521, 95%CI = -28968, -2074). Our findings suggest that chronic HAP exposure through BMF use adversely affects proportions of B lymphocytes, particularly memory B cells, plasma IgE levels and functions of antigen presenting cells in rural women.

Cardiovascular diseases risk prediction in patients with diabetes: Posthoc analysis from a matched case-control study in Bangladesh.

PURPOSE: This study aimed to investigate the estimated 10-year predicted risk of developing cardiovascular diseases (CVD) among participants with and without diabetes in Bangladesh. METHODS: We performed posthoc analysis from a matched case-control study conducted among 1262 participants. A total of 631 participants with diabetes (case) were recruited from a tertiary hospital, and 631 age, sex and residence matched participants (control) were recruited from the community in Dhaka, Bangladesh. Socioeconomic anthropometric, clinical and CVD risk factor data were collected from the participants. The 10-year estimated CVD risk was calculated using the Framingham Risk Score, which has reasonable validity in South Asians. RESULTS: The mean (SD) age of the participants were 51 (10) years. Total 52.3% of cases and 17.2% of controls were at high risk for CVD. The 10-year risk of CVD increased by age and was higher among males in both groups. Among the control group, high CVD risk was more prevalent among higher education and income groups. More than 85% of the tobacco smokers and 70% of chewing tobacco users in the case group were at high risk of CVD. Prevalence of high CVD risk among non-smokers cases was 8.6%. About 35% of hypertensive participants in the control group were at high risk of CVD. CONCLUSION: Bangladeshi patients with diabetes showed a significant burden of CVD risk at a relatively younger age. Strategies for reducing tobacco use and improving BP control in people with diabetes is needed for lowering future CVD risks.

Exposure to household air pollutants and endothelial dysfunction in rural Bangladesh: A cross-sectional study.

More than one third of world's population use biomass fuel for cooking that has been linked to an array of adverse health hazards including cardiovascular mortality and morbidity. As part of Bangladesh Global Environmental and Occupational Health (GEO Health) project, we assessed whether household air pollution (HAP) was associated with dysfunction in microvascular circulation (measured by reactive hyperemia index [RHI]). METHODS: We measured exposure to HAP (particulate matter [PM2.5], carbon monoxide [CO], and black carbon [BC]) for 48 hours of 200 healthy nonsmoker adult females who used biomass fuel for cooking. Exposure to PM2.5 and BC were measured using personal monitor, RTI MicroPEM (RTI International, NC) with an internal filter that had been both pre- and post-weighed to capture the deposited pollutants concentration. Lascar CO logger was used to measure CO. Endothelial function was measured by forearm blood flow dilatation response to brachial artery occlusion using RHI based on peripheral artery tonometry. A low RHI score (<1.67) indicates impaired endothelial function. RESULTS: Average 48 hours personal exposure to PM2.5 and BC were 144.15 µg/m3 (SD 61.26) and 6.35 µg/m3 (SD 2.18), respectively. Interquartile range for CO was 0.73 ppm (0.62-1.35 ppm). Mean logarithm of RHI (LnRHI) was 0.57 in current data. No statistically significant association was observed for LnRHI with PM2.5 (odds ratio [OR] = 0.97; 95% confidence interval [CI] = 0.92, 1.01; P = 0.16), BC (OR = 0.85; 95% CI = 0.72, 1.01; P = 0.07), and CO (OR = 0.89; 95% CI = 0.64, 1.25; P = 0.53) after adjusting for potential covariates. CONCLUSIONS: In conclusion, HAP was not associated with endothelial dysfunction among nonsmoking females in rural Bangladesh who used biomass fuel for cooking for years.

Psychosocial stress, bicultural identity integration, and bicultural self-efficacy among Hispanic emerging adults.

Most studies on psychosocial stress among Hispanics have focused on risk factors. To better understand psychosocial stress among this population, this study aimed to examine components of bicultural identity integration and bicultural self-efficacy, that may be associated with lower psychosocial stress among Hispanic emerging adults (ages 18-25). This aim was tested on a cross-sectional sample of Hispanic emerging adults (Mage = 21.30, SD = 2.09) that included 200 participants (Arizona n = 99, Florida n = 101). The sample included men (n = 98) and women (n = 102). Most participants were US-born (70%), college students (69.5%), and of Mexican heritage (44%). Standardized coefficients from a hierarchical multiple regression model indicate that higher levels of the bicultural harmony component of bicultural identity integration (ß = -0.26, p < 0.001) and the social groundedness component of bicultural self-efficacy (ß = -0.23, p < 0.01) were associated with lower levels of psychosocial stress. To our knowledge, this is the first study to examine components of bicultural identity integration and bicultural self-efficacy and their respective associations with psychosocial stress among any racial/ethnic group. Thus, more studies are needed to replicate our findings to determine if bicultural identity integration and bicultural self-efficacy should be considered in psychosocial stress interventions for Hispanics.

Undiagnosed Isolated Systolic and Diastolic Hypertension Subtypes and Their Correlates in Bangladesh: A Nationwide Survey.

OBJECTIVES: This study was performed to identify the distribution of undiagnosed isolated hypertension subtypes and their correlates amongst adults aged 35 years and older in Bangladesh using data from the Bangladesh Demography and Health Survey 2011. METHODS: Out of a total of 17,964 selected households, 7,880 were included in the final analysis for this study. Systolic and diastolic blood pressure (BP) were measured 3× at 10-minute intervals. Hypertension subtypes were defined for individuals not under antihypertensive treatment as systolic-diastolic hypertension (SDH): systolic BP (SBP) ≥ 140 mm Hg and diastolic BP (DBP) ≥ 90 mm Hg; isolated diastolic hypertension (IDH): SBP < 140 mm Hg and DBP ≥ 90 mm Hg, and isolated systolic hypertension (ISH): SBP ≥140 mm Hg and DBP < 90 mm Hg. RESULTS: The predominant hypertension subtypes were SDH and IDH [5.2%; 95% confidence interval (CI): 4.7-5.1] followed by ISH (3.8%; 95% CI: 3.4-4.2). Multiple logistic regression showed that age and gender were significant predictors of ISH. SDH was associated with females [odds ratio (OR): 1.8; 95% CI: 1.3-2.6], the older age group (OR-7.4; 95% CI: 4.3-12.7), and overweight or obese individuals (OR: 1.6; 95% CI: 1.1-2.4). Non-manual work (OR: 1.5; 95% CI: 1.0-2.0]) and being overweight or obese (OR: 1.9; 95% CI: 1.4-2.8) were factors associated with IDH. CONCLUSION: ISH, IDH and SDH represent salient subtypes of hypertension in Bangladesh. To identify preventive intervention for averting adverse cardiovascular events, further research is needed.

Overweight and abdominal obesity as determinants of undiagnosed diabetes and pre-diabetes in Bangladesh.

BACKGROUND: Type 2 diabetes and pre-diabetes are an increasing pandemic globally and often remain undiagnosed long after onset in low-income settings. The objective of this study is to assess the determinants and prevalence of undiagnosed diabetes and pre-diabetes among adults in Bangladesh. METHODS: In an exploratory study, we performed oral glucose tolerance test on 1243 adults ≥20 years of age from urban Mirpur, Dhaka (n = 518) and rural Matlab, Chandpur (n = 725) who had never been diagnosed with diabetes or pre-diabetes. We collected data on socioeconomic, demographic, past medical history, physical activity, and measured weight, height, waist and hip circumferences, and blood pressure. Risk factors associated with undiagnosed diabetes and pre-diabetes were examined using a multiple logistic regression model. RESULTS: Overall prevalence of diabetes and pre-diabetes was 6.6 % (95 % CI 5.3, 8.1) and 16.6 % (14.5, 18.7) respectively, with both being significantly higher in urban than rural populations (diabetes 12.2 % vs 2.6 % respectively, p < 0.000; pre-diabetes 21.2 % vs 13.2 %, p < 0.001). After adjustment the variables, urban residence (OR 2.5 [95 % CI 1.02, 5.9]), age group 40-59 y (2.9 [1.7-5.2]), ≥60 y (8.1 [2.8-23.8]), overweight (2.2 [1.3-3.9]), abdominal obesity (3.3 [1.8-6.0]) and high WHR 5.6 (2.7-11.9) were all significant predictors of diabetes. Significant predictors of pre-diabetes included age group 40-59 (1.6 [1.1-2.2]), female sex (1.5 [1.0-2.2]), abdominal obesity (1.7 [1.2-2.4]) and high WHR (1.6 [1.2-2.3]). CONCLUSION: Both overweight and abdominal obesity contribute to the hidden public health threat of undiagnosed diabetes and pre-diabetes. Awareness raising and screening of high risk groups combined with a tailored approach are essential for halting the epidemic of diabetes and pre-diabetes in Bangladesh.
