INTRODUCTION:

Childhood obesity disproportionately affects rural populations; therefore, promoting healthy eating among rural children is essential. Teachers are important role models for children and can influence children's eating behaviors through their own behaviors and beliefs about food. This study examined the food-related practices and beliefs of rural elementary and middle school teachers.

METHODS:

Data were used from the SNACZ study, a school- and community-based trial conducted in rural Oregon. Kindergarten through eighth-grade teachers (n=87), teaching students usually aged 5-14 years, from eight rural school districts completed a baseline survey in November 2012 concerning their classroom food practices, eating behaviors at …

Community Health Faculty Publications and Presentations

Background: Many environmental factors have been independently associated with preterm birth (PTB). However, exposure is not isolated to a single environmental factor, but rather to many positive and negative factors that co-occur. The environmental quality index (EQI), a measure of cumulative environmental exposure across all US counties from 2000—2005, was used to investigate associations between ambient environment and PTB.

Methods: With 2000–2005 birth data from the National Center for Health Statistics for the United States (n = 24,483,348), we estimated the association between increasing quintiles of the EQI and county-level and individual-level PTB; we also considered environmental domain-specific (air, …

Community Health Faculty Publications and Presentations

Background: Particulate matter < 2.5 micrometers in aerodynamic diameter (PM2.5) has been variably associated with preterm birth (PTB).

Objective: We classified preterm births into four categories (20–27, 28–31, 32–34, and 35–36 weeks completed gestation) and estimated risk differences (RD) for each category in association with a 1-µg/m3 increase in PM2.5 exposure during each week of gestation.

Methods: We assembled a cohort of singleton pregnancies that completed at least 20 weeks of gestation during 2000-2005 using live birth certificate data from three states (Pennsylvania, Ohio, and New Jersey) (n = 1,940,213; 8% PTB). We estimated mean PM2.5 exposures for each week of gestation from monitor-corrected Community Multi-Scale Air Quality modeling data. RDs were …

Gently Clarifying The Application Of Horn’S Parallel Analysis To Principal Component Analysis Versus Factor Analysis, Alexis Dinno Jan 2014

Gently Clarifying The Application Of Horn’S Parallel Analysis To Principal Component Analysis Versus Factor Analysis, Alexis Dinno

Community Health Faculty Publications and Presentations

Horn’s parallel analysis (PA) is an empirical method used to decide how many components in a principal component analysis (PCA) or factors in a common factor analysis (CFA) drive the variance observed in a data set of n observations on p variables (Horn, 1965). This decision of how many components or factors to retain is critical in applications of PCA or CFA to reducing the dimensionality of data in analysis (as when compositing multiple scale items into a single score), and also in exploratory factor analysis where the different contributions of each factor to each observed variable help generate theory …

A Qualitative Study Of Rural Primary Care Clinician Views On Remote Monitoring Technologies, Melinda M. Davis, Jillian M. Currey, Sonya Howk, Molly R. Desordi, Linda Boise, Lyle J. Fagnan, Nancy Vuckovic

Community Health Faculty Publications and Presentations

Purpose: Remote monitoring technologies (RMTs) may improve the quality of care, reduce access barriers, and help control medical costs. Despite the role of primary care clinicians as potential key users of RMTs, few studies explore their views. This study explores rural primary care clinician interest and the resources necessary to incorporate RMTs into routine practice.

Methods: We conducted 15 in-depth interviews with rural primary care clinician members of the Oregon Rural Practice-based Research Network (ORPRN) from November 2011 to April 2012. Our multidisciplinary team used thematic analysis to identify emergent themes and a cross-case comparative analysis to explore variation by …


Comment On “The Effect Of Same-Sex Marriage Laws On Different-Sex Marriage: Evidence From The Netherlands”, Alexis Dinno Jan 2014

Comment On “The Effect Of Same-Sex Marriage Laws On Different-Sex Marriage: Evidence From The Netherlands”, Alexis Dinno

Community Health Faculty Publications and Presentations

In the recent Demography article titled “The Effect of Same-Sex Marriage Laws on Different-Sex Marriage: Evidence From the Netherlands,” Trandafir attempted to answer the question, Are rates of opposite sex marriage affected by legal recognition of same sex marriages? The results of his approach to statistical inference—looking for evidence of a difference in rates of opposite-sex marriage—provide an absence of evidence of such effects. However, the validity of his conclusion of no causal relationship between same-sex marriage laws and rates of opposite-sex marriage is threatened by the fact that Trandafir did not also look for equivalence in rates of opposite-sex …


Same Sex Marriage And The Perceived Assault On Opposite Sex Marriage, Alexis Dinno, Chelsea Whitney Jun 2013

Same Sex Marriage And The Perceived Assault On Opposite Sex Marriage, Alexis Dinno, Chelsea Whitney

Community Health Faculty Publications and Presentations

Background: Marriage benefits both individuals and societies, and is a fundamental determinant of health. Until recently same sex couples have been excluded from legally recognized marriage in the United States. Recent debate around legalization of same sex marriage has highlighted for anti-same sex marriage advocates and policy makers a concern that allowing same sex couples to marry will lead to a decrease in opposite sex marriages. Our objective is to model state trends in opposite sex marriage rates by implementation of same sex marriages and other same sex unions.

Methods and Findings: Marriage data were obtained for all …

Transport is associated with environmental problems, economic losses, health and social inequalities. A number of European and US cities have implemented initiatives to promote multimodal modes of transport. In Latin America changes are occurring in public transport systems and a number of projects aimed at stimulating non-motorized modes of transport (walking and cycling) have already been implemented. Based on articles from peer-reviewed academic journals, this paper examines experiences in Bogota (Colombia), Curitiba (Brazil), and Santiago (Chile), and identifies how changes to the transport system contribute to encourage active transportation. Bus rapid transit, ciclovias, bike paths/lanes, and car use restriction are …

Community Health Faculty Publications and Presentations

Background: The exclusion of participants with invalid accelerometry data (IAD) may lead to biased results and/or lack of generalizability in large population studies. The purpose of this study was to investigate whether demographic, behavioral, and biological differences occur between those with IAD and valid accelerometry data (VAD) among adults using a representative sample of the civilian noninstitutionalized U.S. population. Methods: Ambulatory participants from NHANES (2003-2004) who were 20-85 years of age were included in the current study and wore an ActiGraph 7164 accelerometer for 7 days. A "valid person" was defined as those with 4 or more days of at …


The Hispanic Paradox And Older Adults’ Disabilities: Is There A Healthy Migrant Effect?, Esme Fuller Thomson, Amini Nuru-Jeter, Dawn M. Richardson, Ferrah Raza, Meredeth Minkler Jan 2013

The Hispanic Paradox And Older Adults’ Disabilities: Is There A Healthy Migrant Effect?, Esme Fuller Thomson, Amini Nuru-Jeter, Dawn M. Richardson, Ferrah Raza, Meredeth Minkler

Community Health Faculty Publications and Presentations

The “Hispanic Paradox” suggests that despite rates of poverty similar to African Americans, Hispanics have far better health and mortality outcomes, more comparable to non-Hispanic White Americans. Three prominent possible explanations for the Hispanic Paradox have emerged. The “Healthy Migrant Effect” suggests a health selection effect due to the demands of migration. The Hispanic lifestyle hypothesis focuses on Hispanics’ strong social ties and better health behaviors. The reverse migration argument suggests that the morbidity profile in the USA is affected when many Hispanic immigrants return to their native countries after developing a serious illness. We analyzed data from respondents aged …

Frailty is a state of decreased physical functioning and a significant complication of ageing. We examined frailty, energy and macronutrient intake, biomarkers of nutritional status and food insufficiency in US older adult (age ≥ 60 years) participants of the Third National Health and Nutrition Examination Survey (4731). Frailty was defined as meeting ≥ 2 and pre-frailty as meeting one of the following four-item criteria: (1) slow walking; (2) muscular weakness; (3) exhaustion and (4) low physical activity. Intake was assessed by 24 h dietary recall. Food insufficiency was self-reported as ‘sometimes’ or ‘often’ not having enough food to eat. Analyses …


Body Mass Index And The Risk Of Prostate Cancer, Daniel Lee Mcgee, Carlos J. Crespo Oct 2012

Body Mass Index And The Risk Of Prostate Cancer, Daniel Lee Mcgee, Carlos J. Crespo

Community Health Faculty Publications and Presentations

Background: This article presents cohort studies that use data from the National Health Information Survey from 1986 to 1994 and compares the effectiveness of Cox proportional hazards models that assume a linear relationship between body mass index (BMI) and the risk of prostate cancer with models that assume a J-shaped relationship. Methods and results: Our study found that for black males over 40 years of age, neither a linear nor a J-shaped relationship yielded a statistically significant model. With white males over 40 years, assuming a linear relationship did not yield a statistically significant model (P = 0.582). When we …

Community Health Faculty Publications and Presentations

The purpose of this research was to assess the consistency of associations between neighborhood characteristics and pregnancy-related behaviors and outcomes across four nested neighborhood boundaries using race-stratified fixed-slope random-intercept multilevel logistic models. High incivilities was associated with increased smoking, inadequate weight gain and pregnancy-induced hypertension (PIH), while walkability was associated with decreased smoking and PIH for white women across all neighborhood definitions. For African American women, high incivilities was associated with increased smoking and inadequate gestational weight gain, while more walkable neighborhoods appeared protective against smoking and inadequate weight gain in all but the smallest neighborhoods. Associations with neighborhood attributes …

Background: Latina immigrants from Mexico suffer significantly increased morbidity and mortality from cervical cancer when compared with non-Hispanic White women, largely owing to lack of screening and appropriate treatment. Objectives: To demonstrate that by combining the tools of community-based participatory research (CBPR) with the tools of interpretive inquiry, it is possible to address explicit community concerns surrounding a particular problem such as cervical cancer while also examining what other, perhaps less immediately visible, matters consume the time and attention of community members. Methods: We first briefly discuss and compare CBPR as an approach to research and interpretive inquiry as a …


Exploring The Sensitivity Of Horn's Parallel Analysis To The Distributional Form Of Random Data, Alexis Dinno May 2009

Exploring The Sensitivity Of Horn's Parallel Analysis To The Distributional Form Of Random Data, Alexis Dinno

Community Health Faculty Publications and Presentations

Horn's parallel analysis (PA) is the method of consensus in the literature on empirical methods for deciding how many components/factors to retain. Different authors have proposed various implementations of PA. Horn's seminal 1965 article, a 1996 article by Thompson and Daniel, and a 2004 article by Hayton et al., all make assertions about the requisite distributional forms of the random data generated for use in PA. Readily available software is used to test whether the results of PA are sensitive to several distributional prescriptions in the literature regarding the rank, normality, mean, variance, and range of simulated data on a …

Women with lupus are at increased risk for developing cardiovascular disease (CVD). Previous studies of atherosclerosis in SLE have not been representative of the minority groups most affected by lupus and its complications. Therefore, a study of 41 lupus cases and 83 controls was conducted to investigate the relationship between carotid atherosclerosis and inflammation in African-American women. Participation consisted of a questionnaire, physical examination, fasting blood draw, and ultrasound of the carotid arteries. There were observed differences between cases and controls with regard to carotid intima media thickness (IMT) and traditional cardiovascular risk factors, although few reached statistical significance. Tumor …

Exposure to pesticides poses great risk to agricultural workers and their families. Of the approximately 174,000 agricultural workers in Oregon, studies estimate that up to 40% of the workers in Oregon are indigenous and may be particularly vulnerable to the health risks of working in pesticide treated areas. Surveys conducted with Oregon farmworkers suggest that Latino and indigenous farmworkers differ demographically and may have diverse occupational and health needs. All Latino workers reported Spanish as their native language, while indigenous workers spoke several different native languages. Latino workers were employed mostly in orchards (28%) and nurseries (24%), while indigenous workers …
