Platelets, 2022 While several small studies have found that selenium deficiency is associated with low platelet counts, they lack generalizability. We used data from the National Health and Nutrition Examination Surveys collected over a 12-year period.

Distributional data analysis of accelerometer data from the NHANES database using nonparametric survey regression models [PDF]
arXiv, 2021 Accelerometers enable an objective measurement of physical activity levels among groups of individuals in free-living environments, providing high-resolution detail about physical activity changes at different time scales. Current approaches used in the literature for analyzing such data typically employ summary measures such as total inactivity time ...

Serum selenium concentrations and diabetes in U.S. adults : National Health and Nutrition Examination Survey (NHANES) 2003–2004 [PDF]
, 2009 Background: Increasing evidence suggests that high selenium levels are associated with diabetes and other cardiometabolic risk factors. Objectives: We evaluated the association of serum selenium concentrations with fasting plasma glucose, glycosylated ...

Urinary DEHP metabolites and fasting time in NHANES [PDF]
Journal of Exposure Science & Environmental Epidemiology, 2011 Exposure assessment analyses conducted in Europe have concluded that the primary pathway of exposure to di(2-ethylhexyl) phthalate (DEHP) is through the diet. The purpose of this study is to evaluate whether urinary DEHP metabolite data from the 2007-2008 National Health and Nutritional Examination Survey (NHANES) demonstrate relationships with ...

Association between healthy lifestyle combinations and periodontitis in NHANES
BMC Oral Health, 2023 Abstract Background Periodontitis is closely associated with chronic systemic diseases. Healthy lifestyle interventions have health-enhancing effects on chronic systemic disorders and periodontitis, but the extent to which healthy lifestyle combinations are associated with periodontitis is unclear.

International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Background According to the National Health and Nutrition Examination Survey (NHANES), more than 20 million Americans suffer from chronic taste problems. Unfortunately, quantitative testing is rarely performed, self‐reports are inaccurate, and “taste” is often confused with olfaction‐dependent flavors.

Robust Estimation of Loss-Based Measures of Model Performance under Covariate Shift [PDF]
arXiv, 2022 We present methods for estimating loss-based measures of the performance of a prediction model in a target population that differs from the source population in which the model was developed, in settings where outcome and covariate data are available from the source population but only covariate data are available on a simple random sample from the ...

Comparing the magnitude of oral health inequality over time in Canada and the United States
Journal of Public Health Dentistry, Volume 82, Issue 4, Page 453-460, Fall 2022., 2022 Abstract Objectives To assess the magnitude of, and changes in, absolute and relative oral health inequality in Canada and the United States, from the 1970s till the first decade of the new millennium. Methods Data were obtained from four national surveys; two Canadian (NCNS 1970–1972 and CHMS 2007–2009) and two American (HANES 1971–1974 and NHANES ...

A Bayesian Functional Data Model for Surveys Collected under Informative Sampling with Application to Mortality Estimation using NHANES [PDF]
arXiv, 2020 Functional data are often extremely high-dimensional and exhibit strong dependence structures but can often prove valuable for both prediction and inference. The literature on functional data analysis is well developed; however, there has been very little work involving functional data in complex survey settings.

Generalized Multilevel Functional Principal Component Analysis with Application to NHANES Active Inactive Patterns [PDF]
arXiv, 2023 Between 2011 and 2014 NHANES collected objectively measured physical activity data using wrist-worn accelerometers for tens of thousands of individuals for up to seven days. In this study, we analyze minute-level indicators of being active, which can be viewed as binary (since each minute is either active or inactive), multilevel (because there are ...
