Association Between Serum Vitamin D And Bone Mineral Density In Us Population, Hamza M. Sultan

Master of Public Health Program Student Publications

Osteoporosis is a condition where the bones become weak that affects 12.6% of the United States (US) population over 50 years of age. Vitamin D helps to improve bone health as it functions in helping reabsorb calcium from the intestines. Several studies have been conducted on the effects of vitamin D on Bone Mineral Density (BMD), where it has shown that insufficient vitamin D is associated with a reduction in BMD. The purpose is to determine the relationship between serum vitamin D and BMD of the femoral neck in the US population in National Health and Nutrition Examination Survey (NHANES) …

Lead Exposure And Metabolic Syndrome In U.S. Population, Nhanes 2013-2014, Khadra Gukadowr

Master of Public Health Program Student Publications

Background: Lead is a known endocrine disruptor and can impair regulation of blood glucose, blood pressure, abdominal adiposity, blood lipid levels which are risk factors for metabolic syndrome (MetS).

Objective: To study the association of lead exposure and MetS in United States (U.S.) adults.

Methods: Data from 523 male and 528 female participants aged 20 years and older from the 2013 to 2014 National Health and Nutrition Examination Survey (NHANES) were analyzed. Based on blood lead distribution in males and females, participants were categorized into low and high blood lead groups in both genders. Adjusted logistic regression analysis was used …

The Association Of Perfluoroalkyl Substance Exposure And Lung Function In The U.S. Population, Brenna C. Heinle

Master of Public Health Program Student Publications

Background/Aim: Perfluoroalkyl substances (PFASs) are chemical compounds used in consumer products and are linked with increase in cholesterol, thyroid disease, and pregnancy-induced hypertension. However, their association with lung function is not completely understood.

Methods: Cross sectional 2011-12 U.S. population data from the National Health and Nutrition Examination Survey (NHANES) was used (N=1,450, aged 12 to 79 years, 52% men). Serum concentration of four PFASs, perfluorononanoic acid (PFNA), perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), and perfluorohexane sulfonic acid (PFHxS) were assessed using mass spectrometry and were categorized into tertiles. Lung function was measured by spirometry as forced vital capacity (FVC), …

Perfluoroalkyl Substances Exposure And Cancer In Nhanes 2011-2016 U.S. Population, Michael Crowder

Master of Public Health Program Student Publications

Background: Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are persistent synthetic compounds that may have associated health risks.

Purpose: To explore the association between four common detectable serum PFASs perfluorooctanoic acid (PFOA), perfluorooctyl sulfonate (PFOS), perfluorohexane sulfonate (PFHxS), and perfluorononanoic acid (PFNA) and cancer risk in United States (U.S.) adults.

Methods: Data from 4,497 participants from the 2011–2016 National Health and Nutrition Examination Survey (NHANES) were analyzed. Gender stratified adjusted logistic regression analysis was conducted to determine association between serum PFASs tertiles and risk of cancer.

Results: Median (IQR) PFASs were significantly higher in men compared to women, and among individual with …

The Association Of Perfluoroalkyl Substances Exposure And Metabolic Syndrome In U.S. Adults, David B. Leary

Master of Public Health Program Student Publications

Background: Perfluoroalkyl substances (PFASs) are persistent synthetic compounds that have been environmental contaminants since the 1950s. Exposure in the general population can be through food and water ingestion, use of non-stick cookware, and dust from stain-resistant carpet. Studies have suggested PFASs act as endocrine disrupters and to affect liver and immune function, as well as cause increases in serum lipid levels.

Objective: To explore the association between six common detectable PFASs and the metabolic syndrome (MetS) in United States (U.S.) adults. Methods: Data from 739 participants aged 20 years and older from the 2013-2014 National Health and Nutrition Examination Survey …

Association Of Cadmium Exposure With Bone Mineral Density In U.S. Adults, Joseph P. Taggart

Master of Public Health Program Student Publications

Background: Cadmium is a toxic heavy metal and environmental pollutant; general population exposure is through occupation, diet, and smoking. Cadmium is associated with lower bone mineral density (BMD) and higher risk of fractures in women. This association is not fully known in men.

Objective: Given the toxicity and global dispersion of cadmium, we explored its association with BMD in U.S. men and women.

Methods: Data from 914 participants from the National Health and Nutrition Examination Survey 2013-2014 was utilized. Multivariable regression analysis was used to determine the independent association between cadmium exposure and BMD controlling for age, body mass index, …
