Cooking and heating with solid fuels results in high levels of household air pollutants, including particulate matter (PM); however, limited data exist for size fractions smaller than PM2.5 (diameter less than 2.5 μm). We collected 24-h time-resolved measurements of PM2.5 (n = 27) and particle number concentrations (PNC, average diameter 10–700 nm) (n = 44; 24 with paired PM2.5 and PNC) in homes with wood-burning traditional and Justa (i.e., with an engineered combustion chamber and chimney) cookstoves in rural Honduras.

The median 24-h PM2.5 concentration (n = 27) was 79 μg/m3 (interquartile range [IQR]: 44–174 μg/m3); traditional (n = 15): …

Nanomaterial-Agrichemical Interactions: Association Of Environmental Herbicides With Two-Dimensional Graphene Nanoplatelets, Nudar A. Bhuiya

The Journal of Purdue Undergraduate Research

Atrazine and glyphosate are the two most common agricultural herbicides used in the United States. Both herbicides can move in the environment, which results in contamination of drinking water sources. Graphene nanoplatelets (GNPs) are an emerging nanoparticle with potential uses for the remediation of environmental contamination. The first aim of this study was to determine binding interactions between atrazine and GNPs to mimic a mixture composition. To determine binding interactions, GNPs with different functional groups (none, carboxylated, or aminylated) were evaluated. GNPs at concentrations of 0, 0.5, 1, 2, or 3 mg/ml were incubated with atrazine at 3 ppb (μg/L) …

Growing evidence links household air pollution exposure from biomass-burning cookstoves to cardiometabolic disease risk. Few randomized controlled interventions of cookstoves (biomass or otherwise) have quantitatively characterized changes in exposure and indicators of cardiometabolic health, a growing and understudied burden in low- and middle-income countries (LMICs). Ideally, the solution is to transition households to clean cooking, such as with electric or liquefied petroleum gas stoves; however, those unable to afford or to access these options will continue to burn biomass for the foreseeable future. Wood-burning cookstove designs such as the Justa (incorporating an engineered combustion zone and chimney) have the potential …

Short Relative Leg Length Is Associated With Overweight And Obesity In Mexican Immigrant Women, Mireya Vilar-Compte, James Macinko, Beth C. Weitzman, Carlos M. Avendaño-Villela

Department of Public Health Scholarship and Creative Works

Background: Prior research suggests that undernutrition and enteric infections predispose children to stunted growth. Undernutrition and infections have been associated with limited access to healthy diets, lack of sanitation, and access barriers to healthcare - all associated with human rights. Stunting has also been documented to be a major determinant of subsequent obesity and non-communicable diseases. Short leg length relative to stature during adulthood seems to be a good proxy indicator tracking such barriers, and has been reported to be associated with adverse health effects during adulthood. Our objective was to examine the association between relative leg length (as measured …

Ecological Determinants Of Respiratory Health: Examining Associations Between Asthma Emergency Department Visits, Diesel Particulate Matter, And Public Parks And Open Space In Los Angeles, California, Jason A. Douglas, Reginald S. Archer, Serena E. Alexander

Health Sciences and Kinesiology Faculty Articles

Los Angeles County (LAC) low-income communities of color experience uneven asthma rates, evidenced by asthma emergency department visits (AEDV). This has partly been attributed to inequitable exposure to diesel particulate matter (DPM). Promisingly, public parks and open space (PPOS) contribute to DPM mitigation. However, low-income communities of color with limited access to PPOS may be deprived of associated public health benefits. Therefore, this novel study investigates the AEDV, DPM, PPOS nexus to address this public health dilemma and inform public policy in at-risk communities. Optimized Hotspot Analysis was used to examine geographic clustering of AEDVs, DPM, and PPOS at the …

Determinants Of Severe Maternal Morbidity And Its Racial/Ethnic Disparities In New York City, 2008–2012, Renata E. Howland, Meghan Angley, Sang Hee Won, Wendy Wilcox, Hannah Searing, Sze Yan Liu, Emily White Johansson

Department of Public Health Scholarship and Creative Works

Objectives Severe maternal morbidity (SMM) is an important indicator for identifying and monitoring efforts to improve maternal health. Studies have identified independent risk factors, including race/ethnicity; however, there has been limited investigation of the modifying effect of socioeconomic factors. The study aims were to quantify SMM risk factors and to determine if socioeconomic status modifies the effect of race/ethnicity on SMM risk. Methods We used 2008–2012 NYC birth certificates matched with hospital discharge records for maternal deliveries. SMM was defined using an algorithm developed by the Centers for Disease Control and Prevention. Mixed-effects logistic regression models estimated SMM risk by …

Syndemics Of Severity And Frequency Of Elder Abuse: A Cross-Sectional Study In Mexican Older Females, Mireya Vilar-Compte, Pablo Gaitán-Rossi

Department of Public Health Scholarship and Creative Works

Background: Elder abuse is a common phenomenon with important effects on the health and well-being of older adults. There are important gaps in elder abuse measurement, as it is usually reported as the absence or presence of elder abuse, disregarding its severity and frequency.

Objectives: Identify different ways of measuring severity and frequency of elder abuse and assess whether different experiences of severity and frequency suggest syndemic relationships.

Methods: Through a sample of 534 non-institutionalized Mexican older women, we assessed how severity (i.e., number of abusive experiences and number of types of abuses) and frequency (i.e., if abusive experiences had …

D. Brook, T. L. Nelson, J. Volckens, S. J. Reynolds, C. L'Orange, N. Good, K. Koehler, S. Africano, A. B. Osorto Pinel, J. L. Peel

Health Sciences Faculty Publications

Household air pollution from biomass cookstoves is estimated to be responsible for more than two and a half million premature deaths annually, primarily in low and middle‐income countries where cardiometabolic disorders, such as Type II Diabetes, are increasing. Growing evidence supports a link between ambient air pollution and diabetes, but evidence for household air pollution is limited. This cross‐sectional study of 142 women (72 with traditional stoves and 70 with cleaner‐burning Justa stoves) in rural Honduras evaluated the association of exposure to household air pollution (stove type, 24‐hour average kitchen and personal fine particulate matter [PM2.5] mass and black carbon) …

An Exploration Of Barriers To Health Care Access Among Uninsured Patients: Using The Moderating Effect Of Patients’ Enablement, Enedelia L. Jessup

Electronic Theses and Dissertations

ABSTRACT On March 23, 2010, Congress passed the Patient Protection and Affordable Care Act (ACA) to increase value of care, improve clinical outcomes, decrease health care costs, and increase affordability in health care access. The purpose of the study attempts to examine the moderating effects of patient enablement impacting barriers, low socio economic status, and unmet basic needs, toward health care access in uninsured populations post ACA. Only certain aspects of patient enablement in self-management of an individual’s health care goals have been conducted with uninsured populations with barriers toward health care access. The research design was a quantitative, exploratory, …

Wild birds are the primary source of genetic diversity for influenza A viruses that eventually emerge in poultry and humans. Much progress has been made in the descriptive ecology of avian influenza viruses (AIVs), but contributions are less evident from quantitative studies (e.g., those including disease dynamic models). Transmission between host species, individuals and flocks has not been measured with sufficient accuracy to allow robust quantitative evaluation of alternate control protocols. We focused on the United States of America (USA) as a case study for determining the state of our quantitative knowledge of potential AIV emergence processes from wild hosts …

Local Tobacco Control: Application Of The Essential Public Health Services Model In A County Health Department’S Efforts To Put It Out Rockland, Lisa D. Lieberman, Una Diffley, Sandy King, Shelley Chanler, Maryanne Ferrera, Oscar Alleyne, Joan Facelle

Department of Public Health Scholarship and Creative Works

In 2000, Rockland County, a small suburban county north of New York City, dedicated $1 million of its Master Settlement Agreement funds to a comprehensive tobacco control program, Put It Out Rockland. Developed and implemented by the county health department, this program used an essential public health services model and an ongoing financial investment, within the context of strong statewide tobacco control efforts, to lower adult smoking rates to 9.7% and to reduce both smoking among youths and exposure to secondhand smoke over the ensuing decade. By combining state funds and local dollars for a total of $6.75 cost per …

Violence Among Young Adults Receiving Housing Assistance: Vouchers, Race, And Transitions Into Adulthood, Tamara Leech

Department of Public Health Scholarship and Creative Works

Scholarly literature has been very attentive to violence among adolescents whose families receive vouchers. Yet, it provides little information about violence among the more than 400,000 very young adults who head households that receive vouchers. This article explores this relationship, paying particular attention to life course considerations and racial context. Data on 18–22-year-olds, numbering 208, who received housing assistance and participated in the National Longitudinal Survey of Youth 1997 in 2002 indicate that normative theoretical models may not accurately capture the relationship between the transition to adulthood and violence within this group. Results also suggest that among those who experience …

The Significance Of Race For Neighborhood Social Cohesion: Perceived Difficulty Of Collective Action In Majority Black Neighborhoods, Tamara Leech, Tara Hobson-Prater

Department of Public Health Scholarship and Creative Works

This article explores William Julius Wilson's contentions about community cultural traits by examining racial differences in middle class neighborhoods' levels of social cohesion. Specifically, we explore the perceived difficulty of these actions-as opposed to general pessimism about their outcomes-as a potential explanation for low levels of instrumental collective action in Black middle class neighborhoods. Our results indicate that, regardless of other neighborhood factors, majority Black neighborhoods have low levels of social cohesion. We also find that this racial disparity is statistically explained by shared perceptions about the amount of effort required to engage in group action in different neighborhoods. These …

College Student Perceptions On Campus Alcohol Policies And Consumption Patterns, Brenda L. Marshall, Katherine J. Roberts, Joseph Donnelly, Imani N. Rutledge

Department of Public Health Scholarship and Creative Works

Environmental strategies for colleges and universities to reduce alcohol consumption among their students include the development and enforcement of campus alcohol policies. This study examines students' knowledge and attitudes toward campus alcohol policies and how they relate to alcohol consumption and alcohol social norms. A sample of 422 freshman students was surveyed during their first month at a 4-year public college. Findings indicated that the majority of students (89%) were aware of campus policies, yet of those who were aware, less than half (44%) were accepting of these campus rules and regulations. In addition, the majority (79%) of students drank …

Everything's Better In Moderation: Young Women's Gender Role Attitudes And Risky Sexual Behavior, Tamara Leech

Department of Public Health Scholarship and Creative Works

Purpose This study examines the association between gender role attitudes and risky sexual behavior among young women. Previous studies have posed seemingly contradictory arguments: that either traditional attitudes or egalitarian attitudes are associated with riskier behavior. Methods Data are based on the children of the National Longitudinal Survey of Youth, representing 520 sexually active 18–19-year-old women. Propensity radius matching was used to assess differences in rates of multiple sexual partners and sex outside of a committed relationship. Results Relative to moderate gender role attitudes, both egalitarian gender role attitudes and traditional gender role attitudes are associated with higher rates of …

Girls' Perception Of Physical Environmental Factors And Transportation: Reliability And Association With Physical Activity And Active Transport To School, Kelly R. Evenson, Amanda Birnbaum, Ariane L. Bedimo-Rung, James Sallis, Carolyn C. Voorhees, Kimberly Ring, John P. Elder

Department of Public Health Scholarship and Creative Works

Background

Preliminary evidence suggests that the physical environment and transportation are associated with youth physical activity levels. Only a few studies have examined the association of physical environmental factors on walking and bicycling to school. Therefore, the purpose of this study was (1) to examine the test-retest reliability of a survey designed for youth to assess perceptions of physical environmental factors (e.g. safety, aesthetics, facilities near the home) and transportation, and (2) to describe the associations of these perceptions with both physical activity and active transport to school.

Methods

Test and retest surveys, administered a median of 12 days later, …

Need For Cognition And Message Complexity In Motivating Fruit And Vegetable Intake Among Callers To The Cancer Information Service, Pamela Williams-Piehota, Judith Pizarro, Stephanie A. Navarro Silvera, Linda Mowad, Peter Salovey

Department of Public Health Scholarship and Creative Works

This field experiment examined the impact of an individual's need for cognition (NFC; the tendency to enjoy thinking deeply about issues), complex versus simple messages, and the interaction of NFC and message type on encouraging fruit and vegetable consumption. Callers to the Cancer Information Service of the National Cancer Institute (N = 517) were asked to participate in the experiment at the end of their call. Individual NFC was assessed, and participants were assigned randomly to receive a telephone message promoting fruit and vegetable consumption that was either complex and multifaceted or simple and straightforward. Similarly constructed brochures were …

Oral Contraceptive Use And Risk Of Breast Cancer Among Women With A Family History Of Breast Cancer: A Prospective Cohort Study, Stephanie A. Navarro Silvera, Anthony B. Miller, Thomas E. Rohan

Department of Public Health Scholarship and Creative Works

Family history of breast cancer is an established risk factor for breast cancer. In addition, there is evidence that oral contraceptive use may be associated with a moderate increase in breast cancer risk. The three cohort studies that have investigated the relationship between oral contraceptive use and breast cancer risk among women with a family history of breast cancer have yielded mixed results, possibly due to the relatively small sample sizes employed and/or differences in the selection of covariates for inclusion in multivariate models. Therefore, we examined the association between oral contraceptive use and breast cancer risk in a large …

Cigarette Smoking And Risk Of Glioma: A Prospective Cohort Study, Stephanie A. Navarro Silvera, Anthony B. Miller, Thomas E. Rohan

Department of Public Health Scholarship and Creative Works

The etiology of glioma, the most commonly diagnosed malignant brain tumor among adults in the United States, is poorly understood. N‐nitroso compounds are known carcinogens, which are found in cigarette smoke and can induce gliomas in rats. On this basis, it has been hypothesized that cigarette smoking may be associated with an increased risk of glioma. We investigated the association between cigarette smoking and glioma risk in the National Breast Screening Study, which included 89,835 Canadian women aged 40–59 years at recruitment between 1980 and 1985. Linkages to national cancer and mortality databases yielded data on cancer incidence and deaths …

Glycemic Index, Glycemic Load, And Pancreatic Cancer Risk (Canada), Stephanie A. Navarro Silvera, Thomas E. Rohan, Meera Jain, Paul D. Terry, Geoffrey R. Howe, Anthony B. Miller

Department of Public Health Scholarship and Creative Works

There is some evidence that plasma insulin and post-load plasma glucose may be associated with the risk of pancreatic cancer. Glycemic index and glycemic load are measures, which allow the carbohydrate content of individual foods to be classified according to their postprandial glycemic effects and hence their effects on circulating insulin levels. Therefore, we examined pancreatic cancer risk in association with a glycemic index (GI), glycemic load (GL), and intake of dietary carbohydrate and sugar in a prospective cohort of 49,613 Canadian women enrolled in the National Breast Screening Study (NBSS) who completed a self-administered food frequency questionnaire between 1980 …
