    Abstract Parabens are a group of endocrine disruptors that have been associated with health effects such as hypertension, diabetes, oxidative stress and obesity, which are associated with increased mortality risk over time. Women are exposed to higher paraben levels than men through use of consumer products. The current prospective study examines paraben exposure in association with mortality risk for women and men. We analyzed 2005–2008 National Health and Nutrition Examination Survey (NHANES) data on urinary paraben analyte concentrations and covariates in adults aged 20 years and over, prospectively linked to National Center for Health Statistics (NCHS) mortality through 2015 (N = 2939). Proportional hazard regression models examined mortality risk in association with exposures, controlling for covariates for women and men. Covariates included age, race/ethnicity, smoking, education, income, body mass index, physical activity, self-reported health status and baseline health conditions. Women were exposed to significantly higher concentrations of all studied parabens than men. Exposures were highest for methyl paraben. Women had significantly higher mortality risk in association with higher natural log exposure to ethyl (HR = 2.048, 95% CI 1.164–3.601), methyl (HR = 1.312, 95% CI 1.013–1.700), butyl (HR = 2.719, 95% CI 1.591–4.647) and total parabens (HR = 1.292, 95% CI 1.006–1.659). Exposure concentrations were associated with higher mortality risk for men only for ethyl paraben (HR = 2.532, 95% CI 1.217–5.268). Women were found to be at greater mortality risk in association with exposure to ethyl, methyl, butyl and total parabens. These findings require confirmatory research but add to the evidence base that exposure to parabens, probably through consumer products, may have adverse effects on human health, especially for women.

    Abstract Background: Sodium-glucose cotransporter 2 (SGLT2) inhibitors are a relatively new class of antidiabetic drugs with demonstrated renal and cardiovascular disease benefit. This study evaluates the role of SGLT2 inhibitors on the survival of non-small cell lung cancer (NSCLC) patients.
    Methods: We used National Surveillance, Epidemiology and End Results (SEER)-Medicare linked data. Twenty four thousand nine hundred fifteen NSCLC patients newly diagnosed between 2014 and 2017 with pre-exiting diabetes and aged 66 years or older were included and followed to the end of 2019. Information on SGLT2 inhibitors use was extracted from the Medicare Part D file.
    Results: SGLT2 inhibitor use was associated with significantly reduced mortality risk after adjusting for potential confounders (HR = 0.68, 95% CI = 0.60-0.77) with stronger association for longer duration of use (HR = 0.54, 85% CI = 0.44-0.68). Further, we found that SGLT2 inhibitor use was associated with a significant reduced risk of mortality regardless of patients' demographic, tumour characteristics and cancer treatments.
    Conclusion: Our large SEER-Medicare linked data study indicates that SGLT2 inhibitors use was associated with improved overall survival of NSCLC patients with pre-existing diabetes. Further studies are needed to confirm our findings and elucidate the possible mechanisms behind the association.

    Abstract Purpose: Because rural residents, particularly those near mining sites, are susceptible to numerous environmental health hazards, it is important to gain deeper insights into their use and trust of health information, which they may employ to help recognize symptoms, learn ways to reduce exposure, or find health care.
    Methods: We surveyed residents (N = 101) of rural Kentucky, Virginia, and West Virginia to assess predictors of health information source use and trust. A project manager administered face-to-face paper and pencil questionnaires assessing demographics, health status, smoking behavior, and health information use and source trust. Bivariate correlations and ordinary least squares regressions were used to analyze the data.
    Findings: The data suggest that rural individuals frequently use nurses, doctors, and websites to seek health information, whereas traditional media are often not their preferred channel for health information. Media sources were not found as trustworthy as interpersonal and medical health information sources. While only 13.0% of individuals in the sample said they ever turned to county or state health departments for health information, these sources were trusted more than any media source and more than friends. Moreover, living closer to active mining sites-meaning these individuals are at a higher risk of environmental health hazards-predicted even less use of traditional media and greater trust in peer sources.
    Conclusions: Not all sources of health information are equally used or trusted by individuals from a rural disparities population. The findings have implications for health campaign message dissemination and intervention designs targeting individuals in rural Appalachia.

    Abstract Social isolation associated with greater risk for mortality is well documented, however, it is unclear whether and the extent to which social isolation influences mortality through health behaviors. We therefore assessed the mediation between social isolation and mortality by health behaviors. 15,000 adults ages 18-89 years in the Third National Health and Nutrition Examination Survey in the US (NHANES III) (1988-1994) were followed through 2015. The outcomes of overall and cause-specific mortality were assessed by linking with the National Death Index. Social isolation was based on a modified Social Network Index. Mediation analyses were conducted under the counterfactual framework. Compared with participants who were not socially isolated, those who were isolated had significantly increased risk for overall mortality (HR = 1.33, 95% CI: 1.15-1.54), cardiovascular disease (CVD)-specific mortality (HR = 1.28, 95% CI: 1.01-1.62) and mortality from causes other than CVD or cancer (HR = 1.53, 95% CI: 1.22-1.90). Social isolation was not independently associated with risk for cancer-specific mortality. The association between social isolation and cancer-specific mortality was largely (74%) mediated by health behaviors, including smoking, physical activity and quality of diet. The associations between social isolation and CVD or other specific mortality were partly (about one-fifth) explained by unhealthy behaviors. In conclusion, the extent to which social isolation and mortality was mediated by healthy behaviors varies by causes of death. Given mounting evidence that social isolation is increasing in society, it is important to add social isolation to the list of public health concerns in addition to conventional risk factors.

    Abstract Background: Exposure to heavy metals may increase risk of kidney disease, but most studies have examined individual metals or two-way interactions. There is increasing recognition of the importance of studying exposure to metal mixtures and health outcomes.
    Objectives: We used Bayesian kernel machine regression (BKMR) to examine associations between a mixture of four heavy metals and indicators of kidney function.
    Methods: We used NHANES 2015-16 data on 1435 adults aged 40 and over to study cross-sectional associations between blood levels of four heavy metals (Co, Cr, Hg and Pb) and kidney function. Kidney function was assessed by estimated glomerular filtration rate (eGFR) and by albumin to creatinine ratio (ACR), measured continuously and dichotomized into indicators of chronic kidney disease (CKD) and albuminuria, respectively. BKMR tested for non-linearity in the exposure-specific responses to evaluate dose-response relationships between mixtures and outcomes and possible interaction effects among exposures. Interactions among continuous outcomes were identified using the NLinteraction package in R.
    Results: A higher metals mixture was significantly associated with all four measures of kidney function in dose-response patterns. Pb had the strongest association with eGFR, albuminuria and ACR, and the second strongest association with CKD. We also observed an interaction between Pb and Co for eGFR and an interaction between Pb and Cd for ACR.
    Conclusions: Exposure to a co-occurring heavy metals mixture was associated with indicators of poor kidney function. Within this mixture, Pb, Co and Cd considered singly and jointly made the greatest contributions to the observed effects. Future prospective study is needed to confirm the association between metal mixtures and kidney function.

    Abstract The novel coronavirus disease (COVID-19) is primarily respiratory in nature, and as such, there is interest in examining whether air pollution might contribute to disease susceptibility or outcome. We merged data on COVID-19 cumulative prevalence and fatality rates as of May 31, 2020 with 2014-2019 pollution data from the US Environmental Protection Agency Environmental Justice Screen (EJSCREEN), with control for state testing rates, population density, and population covariate data from the County Health Rankings. Pollution data included three types of air emission concentrations (particulate matter<2.5 μm (PM2.5), ozone and diesel particulate matter (DPM)), and four pollution source variables (proximity to traffic, National Priority List sites, Risk Management Plan (RMP) sites, and hazardous waste treatment, storage and disposal facilities (TSDFs)). Results of mixed model linear multiple regression analyses indicated that, controlling for covariates, COVID-19 prevalence and fatality rates were significantly associated with greater DPM. Proximity to TSDFs was associated to greater fatality rates, and proximity to RMPs was associated with greater prevalence rates. Results are consistent with previous research indicating that air pollution increases susceptibility to respiratory viral pathogens. Results should be interpreted cautiously given the ecological design, the time lag between exposure and outcome, and the uncertainties in measuring COVID-19 prevalence. Areas with worse prior air quality, especially higher concentrations of diesel exhaust, may be at greater COVID-19 risk, although further studies are needed to confirm these relationships.

    Abstract We sought to assess the relationship between sleep duration, sleep disturbance, and leukemia incidence among postmenopausal women. This study included 130,343 postmenopausal women aged 50-79 years who were enrolled in the Women's Health Initiative (WHI) during 1993-1998. Information on self-reported typical sleep duration and sleep disturbance was obtained by questionnaire at baseline, and sleep disturbance level was defined according to the Women's Health Initiative Insomnia Rating Scale (WHIIRS). WHIIRS scores of 0-4, 5-8, and 9-20 comprised 37.0%, 32.6%, and 30.4% of all women, respectively. After an average of 16.4 years (2,135,109 cumulative person-years) of follow-up, 930 of the participants were identified as having incident leukemia. Compared with women with the lowest level of sleep disturbance (WHIIRS score 0-4), women with higher sleep disturbance levels (WHIIRS scores of 5-8 and 9-20) had 22% (95% confidence interval (CI): 1.04, 1.43) and 18% (95% CI: 1.00, 1.40) excess risks of leukemia, respectively, after multivariable adjustment. A significant dose-response trend was found for the association between sleep disturbance and leukemia risk (P for trend = 0.048). In addition, women with the highest level of sleep disturbance had a higher risk of myeloid leukemia (for WHIIRS score 9-20 vs. WHIIRS score 0-4, hazard ratio = 1.39, CI: 1.05, 1.83). Higher sleep disturbance level was associated with increased risk of leukemia, especially for myeloid leukemia among postmenopausal women.
