High Arsenic

Cardiovascular diseases (CVDs) have been recognized as the most serious non-carcinogenic detrimental health outcome arising from chronic exposure to arsenic. Drinking arsenic contaminated groundwaters is a critical and common exposure pathway for arsenic, notably in India and other countries in the circum-Himalayan region. Notwithstanding this, there has hitherto been a dearth of data on the likely impacts of this exposure on CVD in India. In this study, CVD mortality risks arising from drinking groundwater with high arsenic (>10 μg/L) in India and its constituent states, territories, and districts were quantified using the population-attributable fraction (PAF) approach. Using a novel pseudo-contouring approach, we estimate that between 58 and 64 million people are exposed to arsenic exceeding 10 μg/L in groundwater-derived drinking water in India. On an all-India basis, we estimate that 0.3–0.6% of CVD mortality is attributable to exposure to high arsenic groundwaters, corresponding to annual avoidable premature CVD-related deaths attributable to chronic exposure to groundwater arsenic in India of between around 6500 and 13,000. Based on the reported reduction in life of 12 to 28 years per death due to heart disease, we calculate value of statistical life (VSL) based annual costs to India of arsenic-attributable CVD mortality of between USD 750 million and USD 3400 million.

Introduction: Estimating effects of population-level increases in obesity on diabetes has important implications for public health policy. Therefore, we used the population attributable fraction (PAF) to quantify trends in the burden of obesity on incident diabetes in key sex and race/ethnicity subgroups over time. Hypothesis: PAFs for obesity attributable incident diabetes will be greatest for women, differ by race/ethnicity and increase over time. Methods: Using data from the Multi-Ethnic Study of Atherosclerosis (MESA), we estimated unadjusted and adjusted hazard ratios (HRs) of obesity on incident diabetes mellitus (DM). We included non-Hispanic White (NHW), non-Hispanic Black (NHB) and Hispanic-Mexican (MA) MESA participants with available data on body mass index and key covariates and without DM at baseline. Next, we estimated the prevalence of obesity in four pooled groups of NHANES survey cycles from 2001-2016 with similar characteristics to MESA participants (age 45-80 years, NHW, NHB, and MA without cardiovascular disease). Lastly, we combined estimates from MESA and NHANES to quantify unadjusted and adjusted PAFs (adjusted for age, income, education, physical activity and diet). Leveraging the objective longitudinal assessment of incident DM in MESA and a nationally representative sample of NHANES, we estimated broadly generalizable PAF estimates over time. Results: Of 3869 MESA participants, mean age was 61 (± 10) years with 47% men, 56% NHW, 31% NHB, and 13% MA. Incidence of DM was 11% with overall adjusted HR of 2.75 (95% CI 2.26, 3.34) for obesity. Prevalence of obesity increased from 34% (32, 37) in 2001-2004 to 41% (39, 44) in 2013-2016. Overall adjusted PAFs ranged from 0.23 to 0.52 over the study period (TABLE), with greatest estimates in NHW women. Conclusions: In conclusion, over time, the proportion of diabetes due to obesity has increased across multiple subgroups of the population, further highlighting the health burden of obesity in the population.

Children spend most of their indoors time at home, which may have substantial influence on their health. We conducted a cross-sectional study in the Tianjin area, China to quantify the incidence of respiratory infections among children, and its association with home environments and lifestyles. The lifetime-ever incidences of croup, pneumonia and ear infection among children aged 0–8 in Tianjin area was 9.2%, 28.7% and 11.6%, respectively. The incidence of common cold infections more than twice per year was 31.3%. Home environments and lifestyles included strong risk factors for childhood respiratory infections. Perceived dry air had the greatest association with childhood common colds (population attributable fraction (PAF = 15.0%). Modern floor covering had the greatest association with croup (PAF = 14.7%) and ear infection (PAF = 34.5%), while infrequent bedding sun-curing had the greatest association with pneumonia (PAF = 18.7%). Condensation (a proxy of poor ventilation) accounted for 12.2% of the incidence of croup (PAF = 12.2%) and frequent common colds (PAF = 8.4%). Our findings indicate that factors related to “modern” home environments and lifestyles are risks for childhood respiratory infections. Modifying such factors might reduce the incidence of respiratory infections among children.
