Prevalence Trend And Disparities In Rheumatoid Arthritis Among Us Adults, 2005–2018, Yingke Xu, Qing Wu Jul 2021

Prevalence Trend And Disparities In Rheumatoid Arthritis Among Us Adults, 2005–2018, Yingke Xu, Qing Wu

Public Health Faculty Publications

Rheumatoid arthritis (RA) trends among US adults and disparities in RA patients in recent years have not been well described. We aimed to examine the trend of RA prevalence and disparities among US adults. Data from the National Health and Nutrition Examination Survey (NHANES) of the years 2005–2018 were analyzed to examine the self-reported RA prevalence trend. Age-adjusted RA prevalence stratified by race/ethnicity and socioeconomic status (SES), as well as associated linear trends, were calculated for both genders. The multivariable adjustment was used to evaluate the association between race, SES, and RA. During 2005–2018, there was no significant linear trend …


Lagged Meteorological Impacts On Covid-19 Incidence Among High-Risk Counties In The United States—A Spatiotemporal Analysis, Lung-Chang Chien, Lung-Wen Antony Chen, Ro-Ting Lin Jul 2021

Lagged Meteorological Impacts On Covid-19 Incidence Among High-Risk Counties In The United States—A Spatiotemporal Analysis, Lung-Chang Chien, Lung-Wen Antony Chen, Ro-Ting Lin

Public Health Faculty Publications

Background: The associations between meteorological factors and coronavirus disease 2019 (COVID-19) have been discussed globally; however, because of short study periods, the lack of considering lagged effects, and different study areas, results from the literature were diverse and even contradictory. Objective: The primary purpose of this study is to conduct more reliable research to evaluate the lagged meteorological impacts on COVID-19 incidence by considering a relatively long study period and diversified high-risk areas in the United States. Methods: This study adopted the distributed lagged nonlinear model with a spatial function to analyze COVID-19 incidence predicted by multiple meteorological measures from …


Lagged Influence Of Fine Particulate Matter And Geographic Disparities On Clinic Visits For Children’S Asthma In Taiwan, Lung-Chang Chien, Yu-An Chen, Hwa-Lung Yu Apr 2018

Lagged Influence Of Fine Particulate Matter And Geographic Disparities On Clinic Visits For Children’S Asthma In Taiwan, Lung-Chang Chien, Yu-An Chen, Hwa-Lung Yu

Recent studies have revealed the influence of fine particulate matter (PM2.5) on increased medication use, hospital admission, and emergency room visits for asthma attack in children, but the lagged influence of PM2.5 on children’s asthma and geographic disparities of children’s asthma have rarely been discussed simultaneously. This study investigated the documented diagnosis of children’s asthma in clinic visits for children aged less than 15 years old that were associated with PM2.5 in two counties located in west-central Taiwan during 2005–2010. The result shows that PM2.5 had a significant lagged effect on children’s asthma for up to 6 days. A significantly …
