In this study we characterized the relationship between temperature and mortality in central Arizona desert cities that have an extremely hot climate. Relationships between daily maximum apparent temperature (ATmax) and mortality for eight condition-specific causes and all-cause deaths were modeled for all residents and separately for males and females ages <65 and ≥65 during the months May–October for years 2000–2008. The most robust relationship was between ATmax on day of death and mortality from direct exposure to high environmental heat. For this condition-specific cause of death, the heat thresholds in all gender and age groups (ATmax = 90–97 °F; 32.2‒ 36.1 °C) were below local median seasonal temperatures in the study period (ATmax = 99.5 °F; 37.5 °C). Heat threshold was defined as ATmax at which the mortality ratio begins an exponential upward trend. Thresholds were identified in younger and older females for cardiac disease/stroke mortality (ATmax = 106 and 108 °F; 41.1 and 42.2 °C) with a one-day lag. Thresholds were also identified for mortality from respiratory diseases in older people (ATmax = 109 °F; 42.8 °C) and for all-cause mortality in females (ATmax = 107 °F; 41.7 °C) and males <65 years (ATmax = 102 °F; 38.9 °C). Heat-related mortality in a region that has already made some adaptations to predictable periods of extremely high temperatures suggests that more extensive and targeted heat-adaptation plans for climate change are needed in cities worldwide.

Comparison Of Screening Methods For Pre-Diabetes And Type 2 Diabetes Mellitus By Race/Ethnicity And Gender, Ashleigh E. Heath

Public Health Theses

INTRODUCTION/OBJECTIVES: Current screening guidelines for pre-diabetes and type 2 diabetes mellitus note that there are discrepancies in diagnosing the disease using the fasting plasma glucose test, oral glucose tolerance test, and HbA1_c in high-risk populations. The objective of this study is to compare the effectiveness of screening methods for type 2 diabetes mellitus (T2DM) and pre-diabetes by race/ethnicity and gender.

METHODS: Secondary analyses of the National Health and Nutrition Examination Survey (NHANES, 2005-2008) were performed using SPSS 19.0. Screening outcomes were assessed and compared for a sample of n=10,566, NHW, NHB, MA, and Multiracial/other men and women. Analyses included …

Factors Associated With Traffic Crashes In Pasto, Colombia: 2005-2006, Adam L. O'Bryant

Public Health Theses

Road traffic injuries (RTI) currently rank as the 11th leading cause of death world wide and the leading cause of injury related deaths worldwide. Globally, road traffic crashes kill over 1.2 million people per year with over 90% of the deaths occurring in low and middle income countries. Pedestrians, cyclists, and motorcyclists, collectively called vulnerable road users, are often times the victims. Therefore, the purpose of this study was to identify the factors that are associated with traffic fatalities as well as the factors that are associated with being a vulnerable road user in traffic injuries and traffic fatalities in …

Demographic Factors Associated With Condom Use In 18-24 Year Olds For Two States, 1998 And 2000/2001, Kimberly R. Glenn

Public Health Theses

Despite knowledge about the transmission of HIV and other sexually transmitted diseases (STDs), young adults continue to participate in sexual risk behaviors such as unprotected sexual intercourse. This study examines factors that influence condom use in adults aged 18-24 years in the United States. Using secondary data from the 1998, 2000, and 2001 Behavioral Risk Factor Surveillance System (BRFSS), univariate and multivariate analyses were conducted to assess the factors influencing condom use stratified by gender and study year. A p-value of <0.05 and 95% confidence intervals were used to determine statistical significance throughout all analysis performed. Univariate analysis found that increased age and being male were associated with increased odds of condom use. Multivariate analysis stratified by study year found that in 1998 increased age and unemployment was associated with increased odds of condom use. In 2000/2001, increased age was the only factor associated with increased odds of condom use. Being female was associated with decreased odds of condom use in that study year. When stratified by gender, only increased age was associated with increased condom use. The study results suggest that the factors influencing condom use vary between gender and year. Since different factors impact condom use for each gender, the interventions designed to increase condom use must be centered on those factors. Since age was one of the consistent factors positively associated with condom use, interventions must begin earlier to affect the decision-making processes of young adults.
