Vitamin D is known for its importance to bone health and calcium metabolism and plays a role in insulin resistance. Recent research has recognized its role in insulin secretion, inflammatory response, and adipose tissue changes as possible reasons for its association with insulin resistance and cardiovascular disease. The CDC (2019) reported that 20% of adolescents are now living with prediabetes. Most individuals with prediabetes progress to type 2 diabetes within ten years. Because many studies have focused on adults of all ages, it is important to research young adults. This study aimed to determine prevention efforts; therefore, the younger adult age group was chosen. The purpose of this research is to explore the relationships among Vitamin D intake, sun exposure, handgrip strength, and Hemoglobin A1c levels in college-age adults. Handgrip strength is a biomarker of malnutrition, and evidence suggests a correlation between Vitamin D and skeletal muscle function. Studies have linked Vitamin D to body weight, the development of metabolic syndrome, and prediabetes. A convenience sample of 18- 28-year-old students with no history of metabolic syndrome, prediabetes, or diabetes was eligible to participate. Following consent, a random subject number along with a link was provided to a questionnaire that included demographic and sun exposure items, Vitamin D food frequency, height and weight, and family history of metabolic syndrome or diabetes. Finally, physical measurements and a self-administered Hemoglobin A1c Test were completed. Data analysis included descriptive statistics, comparison tests, and regression analysis. Regression analysis showed no significant relationships among Vitamin D intake, sun exposure, handgrip strength, and Hemoglobin A1c levels in college-age adults. However, the ANOVA results showed a statistical significance between weight, HgA1c, and handgrip strength. Future studies are needed to explore the relationships between Vitamin D intake and HgA1c measurements in college-aged adults.
