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 …

Differences In Demographic, Behavioral, And Biological Variables Between Those With Valid And Invalid Accelerometry Data: Implications For Generalizability, Paul D. Loprinzi, Bradley J. Cardinal, Carlos J. Crespo, Gary R. Brodowicz, Ross E. Andersen, Ellen Smit

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 …

Community Health Faculty Publications and Presentations

Changes in health behaviors (smoking, physical activity, alcohol consumption, and fruit and vegetable consumption) after diagnosis of chronic health conditions (heart disease, cancer, stroke, respiratory disease, and diabetes) were examined among Canadians aged 50 or older. Results from 12 years of longitudinal data from the Canadian National Population Health Survey indicated relatively modest changes in behavior. Although significant decreases in smoking were observed among all groups except those with respiratory disease, at least 75% of smokers did not quit. No significant changes emerged in the percentage meeting physical activity recommendations, except those with diabetes, or in excessive alcohol consumption, except …

Lower Nutritional Status And Higher Food Insufficiency In Frail Older Us Adults, Ellen Smit, Kerri M. Winters-Stone, Paul D. Loprinzi, Alice M. Tang, Carlos J. Crespo

Community Health Faculty Publications and Presentations

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

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 …

A Study Of Riders' Noise Exposure On Bay Area Rapid Transit Trains, Alexis Dinno, Cynthia Powell, Margaret Mary King

Community Health Faculty Publications and Presentations

Excessive noise exposure may present a hazard to hearing, cardiovascular and psychosomatic health. Mass transit systems, such as the Bay Area Rapid Transit (BART) system, are potential sources of excessive noise. The purpose of this study was to characterize transit noise and riders' exposure to noise on the BART system using three dosimetry metrics. We made 268 dosimetry measurements on a convenience sample of 51 line segments. Dosimetry measures were modeled using linear and non-linear multiple regression as functions of average velocity, tunnel enclosure, flooring, and wet weather conditions, and presented visually on a map of the BART system. This …

Community-Based Approaches To Reduce Toxins In Housing: Lessons Learned From Working With Diverse Communities, Erin Mcnally, Ian Blazina, Stephanie Farquhar

Community Health Faculty Publications and Presentations

This article will review lessons learned from a community-based participatory research project with Latino and Somali residents in Portland, Oregon. The aim of the Healthy Futures Collaborative (HFC) project was to reduce in-home environmental health hazards associated with childhood respiratory illness and asthma through a process that strengthened social support and civic engagement. Using a community-based approach, the HFC trained community residents as community scientists to ensure local leadership and participation. Results suggest an increase in Somali and Latino residents' knowledge of environmental stressors and changes in behavior that may improve indoor environmental quality. Especially when working with historically marginalized …

Interpretations Of Interpretations: Combining Community-Based Participatory Research And Interpretive Inquiry To Improve Health, Jessica Gregg, Lourdes Centurion, Julio Maldonado, Raquel Aguillon, Rosemary Carmela Celaya-Alston, Stephanie Farquhar

Community Health Faculty Publications and Presentations

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 …

Inflammatory Biomarkers And Subclinical Atherosclerosis In African-American Women With Systemic Lupus Erythematosus (Sle), Edith M. Williams, Carlos J. Crespo, Joan Dorn

Community Health Faculty Publications and Presentations

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 …

Occupational Health And Safety Status Of Indigenous And Latino Farmworkers In Oregon, Stephanie Farquhar, Nancy M. Goff, Nargess Shadbeh, Julie Samples, Santiago Ventura, Valentin Sanchez, Pamela Rao, Shelley Davis

Community Health Faculty Publications and Presentations

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 …

Loop Analysis Of Causal Feedback In Epidemiology: An Illustration Relating To Urban Neighborhoods And Resident Depressive Experiences, Alexis Dinno

Community Health Faculty Publications and Presentations

The causal feedback implied by urban neighborhood conditions that shape human health experiences, that in turn shape neighborhood conditions through a complex causal web, raises a challenge for traditional epidemiological causal analyses. This article introduces the loop analysis method, and builds off of a core loop model linking neighborhood property vacancy rate, resident depressive symptoms, rate of neighborhood death, and rate of neighborhood exit in a feedback network. I justify and apply loop analysis to the specific example of depressive symptoms and abandoned urban residential property to show how inquiries into the behavior of causal systems can answer different kinds …

Advancing Transdisciplinary And Translational Research Practice: Issues And Models Of Doctoral Education In Public Health, Linda Neuhauser, Dawn M. Richardson, Sonja Mackenzie, Meredith Minkler

Community Health Faculty Publications and Presentations

Finding solutions to complex health problems, such as obesity, violence, and climate change, will require radical changes in cross-disciplinary education, research, and practice. The fundamental determinants of health include many interrelated factors such as poverty, culture, education, environment, and government policies. However, traditional public health training has tended to focus more narrowly on diseases and risk factors, and has not adequately leveraged the rich contributions of sociology, anthropology, economics, geography, communication, political science, and other disciplines. Further, students are often not sufficiently trained to work across sectors to translate research findings into effective, large-scale sustainable actions. During the past 2 …
