Poverty status influences obesity and dietary quality, and dietary quality influences obesity. How these relationships differ by sex is unclear. The current study aims were to 1) determine whether dietary quality mediates the relation between income-to-poverty ratio (IPR) and overweight/obesity (OV/OB) among men and women, separately, and 2) determine whether either of the mediated paths differs by sex. Four cycles of NHANES (2007-2014) were merged to obtain an unweighted study sample of 12,768 adults with complete data. Exposure variables included self-reported measures of IPR, Healthy Eating index (HEI) total score to measure diet quality, and sex. Direct assessment of height …

Decline In Telomere Length By Age And Effect Modification By Gender, Allostatic Load And Comorbidities In National Health And Nutrition Examination Survey (1999-2002), Saruna Ghimire, Carl V. Hill, Francisco S. Sy, Rachelle Rodriguez

Public Health Faculty Publications

Background: This study aims to assess the decline in telomere length (TL) with age and evaluate effect modification by gender, chronic stress, and comorbidity in a representative sample of the US population. Methods: Cross-sectional data on 7826 adults with a TL measurement, were included from the National Health and Nutrition Examination Survey, years 1999–2002. The population rate of decline in TL across 10-year age categories was estimated using crude and adjusted regression. Results: In an adjusted model, the population rate of decline in TL with age was consistent and linear for only three age categories: 20–29 (β = -0.0172, 95% …

The Impact Of Pedestrian Crossing Flags On Driver Yielding Behavior In Las Vegas, Nv, Sheila Clark, Courtney Coughenour, Kelly Bumgarner, Hanns De La Fuente-Mella, Chantel Reynolds, James Abelar

Public Health Faculty Publications

Walking is the most affordable, accessible, and environmentally friendly method of transportation. However, the risk of pedestrian injury or death from motor vehicle crashes is significant, particularly in sprawling metropolitan areas. The purpose of this study was to examine the effect of pedestrian crossing flags (PCFs) on driver yielding behaviors. Participants crossed a marked, midblock crosswalk on a multilane road in Las Vegas, Nevada, with and without PCFs, to determine if there were differences in driver yielding behaviors (n = 160 crossings). Trained observers recorded (1) the number of vehicles that passed in the nearest lane without yielding while the …


Health-Information Seeking And Intention To Quit Smoking: Do Health Beliefs Have A Mediating Role?, Soumya Upadhyay, Justin Loard, Maxim Gakh Aug 2019

Health-Information Seeking And Intention To Quit Smoking: Do Health Beliefs Have A Mediating Role?, Soumya Upadhyay, Justin Loard, Maxim Gakh

Public Health Faculty Publications

Background: Smoking is a leading cause of preventable deaths. Smoking cessation can reduce the risk of smoking-associated disease and death. But smoking cessation involves behaviour change. Existing research indicates that health-information seeking and health-promoting behaviours can be positively associated. However, in the context of smoking, the relationship between seeking health information and intending to quit smoking remains only partially understood. Aim: This study aimed to examine the relationship between seeking health information and intending to quit smoking and to determine whether this relationship is mediated by health beliefs. Methods: We used data from the fourth cycle of the US National …

We aim to examine temporal trends of orthopedic operations and opioid-related hospital stays among seniors in the nation and states of Oregon and Washington where marijuana legalization was accepted earlier than any others. As aging society advances in the United States (U.S.), orthopedic operations and opioid-related hospital stays among seniors increase in the nation. A serial cross-sectional cohort study using the healthcare cost and utilization project fast stats from 2006 through 2015 measured annual rate per 100,000 populations of orthopedic operations by age groups (45–64 vs 65 and older) as well as annual rate per 100,000 populations of opioid-related hospital …

This policy brief examines preventive services state legislation trends in the United States during uncertainty regarding the Affordable Care Act (ACA), which requires certain coverage of 4 evidence-based preventive services categories without additional patient costs under §2713. We used a legal mapping approach to search for and analyze state legislation related to preventive services proposed or enacted over a 25-month period of ACA uncertainty. We screened 1231 bills and coded the 76 screened-in bills. Next, we determined their characteristics and examined trends. Bills originated in 28 states, and 69.7% were not enacted. Only 3.9% contained requirements contingent on ACA modifications. …


Two-Stage Optimal Designs With Survival Endpoint When The Follow-Up Time Is Restricted, Guogen Shan, Hua Zhang Apr 2019

Two-Stage Optimal Designs With Survival Endpoint When The Follow-Up Time Is Restricted, Guogen Shan, Hua Zhang

Public Health Faculty Publications

Background: Survival endpoint is frequently used in early phase clinical trials as the primary endpoint to assess the activity of a new treatment. Existing two-stage optimal designs with survival endpoint either over estimate the sample size or compute power outside the alternative hypothesis space. Methods: We propose a new single-arm two-stage optimal design with survival endpoint by using the one-sample log rank test based on exact variance estimates. This proposed design with survival endpoint is analogous to Simon’s two-stage design with binary endpoint, having restricted follow-up. Results: We compare the proposed design with the existing two-stage designs, including the two-stage …

Studies show that children who attend full-day kindergarten (FDK) experience both academic and developmental benefits compared to children who attend half-day programs. Sectors outside of health, such as education, can have important intended and unintended impacts on health. The purpose of this qualitative study was to understand perceptions of parental and other stakeholders in Southern Nevada (USA) about the education–health link, and to understand priorities regarding how FDK access could affect health. Two 90-minute focus groups were conducted with 14 adult stakeholder participants representing parents, current and former teachers, and community members. Transcripts were analyzed using conventional content analysis. Eight …

Walkability is associated with increased levels of physical activity and improved health and sustainability. The sprawling design of many metropolitan areas of the western U.S., such as Las Vegas, influences their walkability. The purpose of this study was to consider sprawl characteristics along with well-known correlates of walkability to determine what factors influence self-reported minutes of active transportation. Residents from four neighborhoods in the Las Vegas Metropolitan Area, targeted for their high and low walkability scores, were surveyed for their perceptions of street-connectivity, residential-density, land-use mix, and retail–floor-area ratio and sprawl characteristics including distance between crosswalks, single-entry-communities, high-speed streets, shade, …
