Air Pollutants and Breast Cancer Risk: A Parallel Analysis of Five Large US Prospective Cohorts
Objectives. To determine whether outdoor air pollution exposure is associated with breast cancer incidence. Methods. Residential-level concentrations of nitrogen dioxide (NO 2 , parts per billion [ppb]), fine particulate matter (PM 2.5 ; ≤ 2.5 μ/m 3 ) and ozone (ppb) in the United States were estimated for participants of the Nurses’ Health Studies, Women’s Health Initiative Clinical Trials and Observational Study Cohort, and Sister Study using h…
Financial precarity, food insecurity, and psychological distress prospectively linked with use of potentially dangerous dietary supplements during the pandemic in the US
Introduction: Supplements sold with claims to promote weight loss, cleansing/detoxing, increased energy, or boosted immunity can be dangerous, and consumers experiencing extreme stressors may be especially vulnerable to deceptive claims. The purpose of our study was to investigate associations of financial strain and psychological distress during the COVID-19 pandemic with use of supplements sold for weight loss, cleanse/detox, energy, or immunit…
Associations between weight discrimination and the use of potentially harmful dietary supplements during the Covid-19 pandemic in the United States
Associations between Nature Exposure and Health: A Review of the Evidence
There is extensive empirical literature on the association between exposure to nature and health. In this narrative review, we discuss the strength of evidence from recent (i.e., the last decade) experimental and observational studies on nature exposure and health, highlighting research on children and youth where possible. We found evidence for associations between nature exposure and improved cognitive function, brain activity, blood pressure, …
Social Distancing Associations with Covid-19 Infection and Mortality Are Modified by Crowding and Socioeconomic Status
The SARS-CoV-2 virus is a public health emergency. Social distancing is a key approach to slowing disease transmission. However, more evidence is needed on its efficacy, and little is known on the types of areas where it is more or less effective. We obtained county-level data on COVID-19 incidence and mortality during the first wave, smartphone-based average social distancing (0-5, where higher numbers indicate more social distancing), and censu…
Risk of Covid-19 among front-line health-care workers and the general community: A prospective cohort study
BACKGROUND: Data for front-line health-care workers and risk of COVID-19 are limited. We sought to assess risk of COVID-19 among front-line health-care workers compared with the general community and the effect of personal protective equipment (PPE) on risk. METHODS: We did a prospective, observational cohort study in the UK and the USA of the general community, including front-line health-care workers, using self-reported data from the COVID Sym…
Prenatal Ambient Particulate Matter Exposure and Longitudinal Weight Growth Trajectories in Early Childhood
Air pollution exposure during pregnancy has been associated with impaired fetal growth and postnatal weight gain, but few studies have examined the effect on weight growth trajectories. We examine the association between validated 1 km 2 resolution particulate matter (PM 2.5 ) concentrations, averaged over pregnancy, and sex-specific growth trajectories from birth to age six of participants in the Boston-based Children's HealthWatch cohort (4797 …
Racial Disparities in Associations between Neighborhood Demographic Polarization and Birth Weight
Neighborhood demographic polarization, or the extent to which a privileged population group outnumbers a deprived group, can affect health by influencing social dynamics. While using birth records from 2001 to 2013 in Massachusetts ( n = 629,675), we estimated the effect of two demographic indices, racial residential polarization (RRP) and economic residential polarization (ERP), on birth weight outcomes, which are established predictors of the n…
Estimating the Combined Effects of Natural and Built Environmental Exposures on Birthweight among Urban Residents in Massachusetts
Intrauterine growth has health implications both in childhood and adulthood. Birthweight is partially determined by prenatal environmental exposures. We aim to identify important predictors of birthweight out of a set of environmental, built environment exposures, and socioeconomic environment variables during pregnancy (i.e., fine particulate matter (PM 2.5 ), temperature, greenness, walkability, noise, and economic indices). We included all sin…
Effects of Maternal Homelessness, Supplemental Nutrition Programs, and Prenatal PM2.5 on Birthweight
Few studies examined the impact of maternal socioeconomic status and of its combined effects with environmental exposures on birthweight. Our goal was to examine the impact of maternal homelessness (mothers ever homeless or who lived in shelters during pregnancy) and participation in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) during pregnancy in conjunction with air pollution exposure on birthweight in the Bo…
Effect of Residential Greenness and Nearby Parks on Respiratory and Allergic Diseases among Middle School Adolescents in a Chinese City
Research on the health impacts of green environments has mainly been conducted in developed countries. Differences in the urban forms between China and Western countries make it essential to understand the role of greenspace in Chinese settings. From 2014 to 2015, middle school students ( n = 5643) in Suzhou, China were enrolled in a study on the health effect of residential greenness. The normalized difference vegetation index (NDVI) and distanc…
Neighborhood Greenness Attenuates the Adverse Effect of PM2.5 on Cardiovascular Mortality in Neighborhoods of Lower Socioeconomic Status
Features of the environment may modify the effect of particulate matter ≤2.5 μm in aerodynamic diameter (PM 2.5 ) on health. Therefore, we investigated how neighborhood sociodemographic and land-use characteristics may modify the association between PM 2.5 and cardiovascular mortality. We obtained residence-level geocoded cardiovascular mortality cases from the Massachusetts Department of Public Health ( n = 179,986), and PM 2.5 predictions from …
Global estimates of mortality associated with long-term exposure to outdoor fine particulate matter
Exposure to ambient fine particulate matter (PM 2.5 ) is a major global health concern. Quantitative estimates of attributable mortality are based on disease-specific hazard ratio models that incorporate risk information from multiple PM 2.5 sources (outdoor and indoor air pollution from use of solid fuels and secondhand and active smoking), requiring assumptions about equivalent exposure and toxicity. We relax these contentious assumptions by co…

Exposure to Greenness and Mortality in a Nationwide Prospective Cohort Study of Women
BACKGROUND: Green, natural environments may ameliorate adverse environmental exposures (e.g., air pollution, noise, and extreme heat), increase physical activity and social engagement, and lower stress. OBJECTIVES: We aimed to examine the prospective association between residential greenness and mortality. METHODS: Using data from the U.S.-based Nurses' Health Study prospective cohort, we defined cumulative average time-varying seasonal greenness…

Neighborhood Self-Selection: The Role of Pre-Move Health Factors on the Built and Socioeconomic Environment
Residential self-selection bias is a concern in studies of neighborhoods and health. This bias results from health behaviors predicting neighborhood choice. To quantify this bias, we examined associations between pre-move health factors (body mass index, walking, and total physical activity) and post-move neighborhood factors (County Sprawl Index, Census tract socioeconomic status (SES)) in the Nurses' Health Study (n = 14,159 moves from 1986-200…
Spatial clustering of physical activity and obesity in relation to built environment factors among older women in three U.S. states
Spatial clustering techniques can identify high and low risk areas for physical activity and obesity. Although covariates significantly differed inside and outside the clusters, patterns of differences were mostly inconsistent. The findings from these spatial analyses could eventually facilitate the design and implementation of more resource-efficient, geographically targeted interventions for both physical activity and obesity

In this group of trucking industry workers, childhood and recent exposures to SHS were related to respiratory symptoms
Urban Sprawl, Physical Activity, and Body Mass Index: Nurses’ Health Study and Nurses’ Health Study II
Objectives. We evaluated the association between the county sprawl index, a measure of residential density and street accessibility, and physical activity and body mass index (BMI). Methods. We conducted a multilevel cross-sectional analysis in a sample of Nurses’ Health Study participants living throughout the United States in 2000 to 2001 (n = 136 592). Results. In analyses adjusted for age, smoking status, race, and husband’s education, a 1-SD…
Nicotine Contamination in Particulate Matter Sampling
We have addressed potential contamination of PM(2.5) filter samples by nicotine from cigarette smoke. We collected two nicotine samples - one nicotine sampling filter was placed inline after the collection of PM(2.5) and the other stood alone. The overall correlation between the two nicotine filter levels was 0.99. The nicotine collected on the "stand-alone" filter was slightly greater than that on the "in-line" filter (mean difference = 1.10 mug…
