The Relationship Between Vitamin D And Calcium/Dairy Intake And Obesity In Children, Jason Barry

Nutrition Theses

Objective: The aim of this study is to examine the relationship between vitamin D and calcium intake and obesity in a population of young adolescents who participated in a Vitamin D and Sunlight Exposure study in Pittsburgh, PA.

Participants: 252 healthy 6 to 14.9 year old young adolescents (54% male, 69% African American) were recruited between June 2006 and December 2009.

Main outcome measures: Weight status, BMI, vitamin D intake, calcium intake, vitamin D and calcium rich food intake.

Results: A significant difference by race was observed with 30.1% of African Americans and 8.5% of Caucasians being obese (P<0.01). No difference was found by gender. Median (25%, 75%) vitamin D intake in the total population was 254.9 IU (146.8, 407.3) which is below the level recommended by the Institute of Medicine. Median calcium intake in the total population was 1193.6 mg (752.8, 1161.1) which met recommended guidelines. Median vitamin D intake differed by weight status (normal, overweight, obese) in the total population (259.5 IU, 325.2 IU and 181.9 IU, respectively; P=0.015). A similar pattern was observed for calcium (1193.4 mg, 1416.3 mg and 911.6 mg, respectively; P=0.016). No correlation was found between vitamin D or calcium intake and BMI in the total population or by race and gender.

Oxidized Lipid And Its Association With Markers Of Adiposity Nhanes-2005-06, Payal Arora

Nutrition Theses

ABSTRACT

Background: Polyunsaturated fatty acids (PUFA) are found in nuts and seeds, salad dressings and vegetable oil and are prone to oxidation during storage and food preparation. Evidence supports that consumption of oxidized lipids promotes atherosclerosis and glucose intolerance in animal models. However there is a dearth of evidence with regard to the amount of oxidized lipids consumed and its association with parameters of adiposity and glucose homeostasis in humans.

Objective: The objective of this study is to estimate the amount of oxidized lipids in common foods and the oxidized lipid consumption in the US population using the data from …
