Article Synopsis
- The study investigates the link between expiratory central airway collapse and obstructive sleep apnea (OSA) severity in men and women, emphasizing the physical differences in upper airways between genders.
- Utilizing data from 901 participants who underwent chest CT and sleep studies, it highlights that women experience more significant expiratory tracheal collapse correlated with OSA severity than men.
- The findings suggest that gender-specific factors play a crucial role in the severity of OSA, with women showing a stronger association between airway structure changes and sleep apnea than men.
Background: The all-cause and cause-specific mortality risk associated with sleep latencies in the general adult population is unknown. We aimed to investigate the association of habitual prolonged sleep latency with long-term all-cause and cause-specific mortality in adults.
Methods: The Korean Genome and Epidemiology Study (KoGES) is a population-based prospective cohort study comprising community-dwelling men and women aged 40-69 years from Ansan, South Korea.
Background And Aims: There is a demand for longitudinal studies that use both objective and subjective measures of physical activity to investigate the association of physical activity with the change in carotid intima-media thickness (CIMT). In order to investigate such association, we conducted an 8-year follow-up study that used both objective and subjective measures of physical activity.
Methods: This cohort study used subsamples of the ongoing Korean Genome and Epidemiology Study (KoGES).
Background: Obstructive sleep apnoea (OSA) is associated with increased risk of type 2 diabetes. However, results from large population-based prospective cohort studies are rare. The main aim of the present study was to investigate the relative risk of 8-year incident type 2 diabetes in relation to OSA severity in a prospective cohort study of middle-aged and older adults.

Objective: To examine the associations of OSA with cognition and white matter (WM) integrity over a 4-year period.
Design, Setting, And Participants: This prospective cohort study was conducted in a community-based adult population among participants who had both baseline (2011-2014) and 4-year follow-up (2015-2018) polysomnography, diffusion tensor imaging, and cognitive assessment data.
Background: Recent studies have reported that height is inversely associated with blood pressure and hypertension. However, there is lack of comprehensive findings from Bangladesh in this regard.
Objective: The purpose of this study was to explore the association between height and blood pressure in a Bangladeshi population.
Although heavy alcohol consumption has been identified as a risk factor for adverse cognitive functioning, it currently remains unclear whether moderate alcohol consumption exerts similar effects. Observational studies previously reported the potential benefits of moderate alcohol consumption on cognition, particularly in the elderly; however, these effects have not yet been demonstrated in Asian populations. The aim of the present study was to investigate the relationship between alcohol consumption levels and global and domain-specific cognitive functions in cognitively intact elderly Japanese men.

Design: A cross-sectional study.
Setting: Rural communities in Bangladesh, Pakistan and Sri Lanka.
Background: The implications of rising obesity for cardiovascular health in middle-income countries has generated interest, in part because associations between obesity and cardiovascular health seem to vary across ethnic groups.
Objective: We assessed general and central obesity in Africa, East Asia, South America, and South Asia. We further investigated whether body mass index (BMI) and waist circumference differentially relate to cardiovascular health; and associations between obesity metrics and adverse cardiovascular health vary by region.
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.
Background: Little is known about long-term changes linking chronic diseases and poverty in low-income countries such as Bangladesh. This study examines how chronic disease mortality rates change across socioeconomic groups over time in Bangladesh, and whether such mortality is associated with households falling into poverty.
Methods: Age-sex standardized chronic diseases mortality rates were estimated across socioeconomic groups in 1982, 1996 and 2005, using data from the health and demographic surveillance system in Matlab, 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.
Objectives: To assess the effect of awareness and advice to seek care on blood pressure (BP) control among patients with hypertension in Bangladesh.
Design: Longitudinal study.
Setting: The study was carried out in icddr,b surveillance sites at rural Matlab in Chandpur district and semi-urban Kamalapur in Dhaka, Bangladesh.
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.
Background: Indoor air pollution (IAP) due to solid fuel use is a major risk factor of respiratory and cardiovascular mortality and morbidity. Rural Matlab in Bangladesh has been partly supplied with natural gas since the early 1990s, which offered a natural experiment to investigate the long-term impact of IAP on cardiopulmonary mortality.
Objective: This study sought to compare adult cardiopulmonary mortality in relation to household fuel type as a surrogate for exposure to indoor air pollution.
