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, …


Low Birth Weight, Very Low Birth Weight And Infant Mortality In San Bernardino County : A Secondary Analysis Of Maternal Factors, Rebecca D. Nanyonjo Jun 2006

Low Birth Weight, Very Low Birth Weight And Infant Mortality In San Bernardino County : A Secondary Analysis Of Maternal Factors, Rebecca D. Nanyonjo

Loma Linda University Electronic Theses, Dissertations & Projects

Purpose: National and state infant mortality rates have slowly declined over the last several years. Despite this reduction, San Bernardino County still has one of the highest infant mortality rates in California and racial disparities between Black and White infants not only persist but continue to widen. These disparities remain at the forefront of concern. Healthy People 2010 target objectives have yet to be reached, while national and state proposed plans have supported the statement that a community's largest health problem is initiated by its infant mortality. The purpose of this study was to investigate maternal factors through use of …


Hormonal And Reproductive Factors And Risk Of Glioma: A Prospective Cohort Study, Stephanie A. Navarro Silvera, Anthony B. Miller, Thomas E. Rohan Mar 2006

Hormonal And Reproductive Factors 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. Given the lower incidence rate of glioma in women than in men, it has been hypothesized that reproductive and hormonal factors may be involved in the etiology of glioma. We conducted a secondary analysis of data from 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 from all causes, respectively, with follow‐up ending between 1998 and …


Carotenoid, Vitamin A, Vitamin C, And Vitamin E Intake And Risk Of Ovarian Cancer: A Prospective Cohort Study, Stephanie A. Navarro Silvera, Meera Jain, Geoffrey R. Howe, Anthony B. Miller, Thomas E. Rohan Feb 2006

It is thought that oxidative stress resulting to repeated ovulation may increase the risk of ovarian cancer by inducing DNA damage (1). Consumption of antioxidants may, therefore, decrease ovarian cancer risk by counteracting oxidative stress and the resultant DNA damage (2, 3). Currently, the epidemiologic evidence regarding associations between antioxidants and risk of ovarian cancer is mixed (4-12). Of the two prospective studies, Kushi et al. (4) and Fairfield et al. (7) both reported no association between β-carotene and ovarian cancer risk. In addition, Fairfield et al. …

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 Jan 2006

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 …


Air Pollutants And Respiratory Symptoms Among Adults, Paulo A. Lotufo Jan 2006

Air Pollutants And Respiratory Symptoms Among Adults, Paulo A. Lotufo

Paulo A Lotufo

Air pollutants are associated with adverse respiratory effects mainly in susceptible groups such as children, elderly people and people with pre-existent respiratory disease. This study was designed to assess the impact of the inorganic composition of particulate matter on 33 adult asthmatics respiratory functions in São Paulo city, Brazil. From May to July 2002, fine and coarse particulate matter fractions were collected and trace metals (Fe2+, Mn2+, Zn2+, Pb2+, Cu2+) and major ions (Na+, Mg2+, K+, Ca2+, NH4 +, Cl-, NO3-, SO42-) composition was determined in each aqueous-extract fraction by Atomic Absorption Spectrometry with Graphite Furnace (AAS-GF) and Ion Chromatography, …


The Acute-Phase Proteins Serum Amyloid A And C Reactive Protein In Transudates And Exudates, Paulo A. Lotufo Jan 2006

The Acute-Phase Proteins Serum Amyloid A And C Reactive Protein In Transudates And Exudates, Paulo A. Lotufo

Paulo A Lotufo

The distinction between exudates and transudates is very important in the patient management. Here we evaluate whether the acute-phase protein serum amyloid A (SAA), in comparison with C reactive protein (CRP) and total protein (TP), can be useful in this discrimination. CRP, SAA, and TP were determined in 36 exudate samples (27 pleural and 9 ascitic) and in 12 transudates (9 pleural and 3 ascitic). CRP, SAA, and TP were measured. SAA present in the exudate corresponded to 10% of the amount found in serum, that is, the exudate/serum ratio (E/S) was 0.10±0.13. For comparison, the exudate/serum ratio for CRP …

Additional Cardiovascular Risk Factors Associated With Excess Weigth In Children And Adolescents. The Belo Horizonte Heart Study, Paulo A. Lotufo

Paulo A Lotufo

OBJECTIVE: To examine the association of overweight and obesity with physical activity, blood pressure (BP) and serum lipid profiles. METHODS Epidemiologic investigation of 1,450 students, between the ages of 6 and 18, in the city of Belo Horizonte, MG. Data: weight, height, BP, skinfold thickness, waist circumference, physical activity, total cholesterol (TC), LDL-c, HDL-c, and dietary habits. RESULTS The prevalence rates for overweight and obesity were 8.4% and 3.1%, respectively. In relation to the students in the lower quartile (Q1) of the distribution of subscapular skinfold, the students in the upper quartile (Q4) presented a 3.7 times higher risk (odds …
