Abstract
The purpose of this descriptive study was to assess the prevalence of metabolic syndrome (MetS), prediabetes and type 2 diabetes (T2DM) in participants who voluntarily participated in a fitness assessment, and to examine associations with routine nutrition intake and overall body composition. One hundred and six participants were recruited. Anthropometric measurements were taken with blood analyses completed for fasting glucose, glycosylated hemoglobin (HbA1c) and lipid panel. A 24-hour diet recall and a dietary screening survey was used to assess nutrient intake, in a sub-set of 36 participants. Statistical analyses utilized partial Spearmans' rank correlations, risk ratios, and Kendall's Tau correlations, with significance level at p < 0.05. Twenty five percent of this sample had ≥ three risk factors for MetS, with elevated fasting glucose and blood pressure being the most prevalent. Twenty percent of the participants had HbA1c levels elevated at the prediabetes range, with no previous diagnosis. Four percent of participants had HbA1c levels elevated at the T2DM range. Two nutrients of interest were correlated to BMI status. Percent kcal from carbohydrate (τ -0.207, p<0.05) had a negative correlation with BMI status and percent kcal from fat intake had a positive correlation (τ 0.217, p<0.05). Findings from this small sample of adults indicate the need for routine assessment of: clustering of MetS risk factors, risk of prediabetes and T2DM and treatment of same. Many participants would benefit from increasing their participation in physical activity, weight loss in regard to overall health improvement, and education to improve diet quality.Entities:
