P14-011 - A Dietary Intervention Comparison of Healthy Young Adults and Those with Metabolic Syndrome

Monday, Jun 11
8:00 AM – 3:00 PM

Objective: To determine if young adults with Metabolic Syndrome (MetS) have different dietary habits than healthy young adults.

Methods: The 8-week nutrition intervention was completed in two cohorts with an "at risk" cohort, and a MetS cohort. Subjects were educated on MyPlate guidelines and counseled weekly by a nutrition specialist. Anthropometrics, complete blood panel, arterial stiffness, and a stool sample were taken at baseline and post-intervention. Each week diet logs and food receipts were collected for compliance. Repeated measures ANOVA test was used to compare differences over the 8-week study between the two cohorts. Matched pairs t-test was used to examine pre-intervention tp post-intervention clinical differences.

Results: Thirty-six young adults enrolled in the healthy "at risk" cohort (C1), and an additional 17 with MetS cohort (C2). Though, based on compliance there was eight individuals eliminated from the analysis (n=30 in C1 and n=15 in C2). No significant changes were seen in physical activity, stress, or sleep. Dietary differences between the two cohorts yielded significant differences in percent protein (p=0.012), fiber (p=0.003), and empty calories (p=0.038). Percent protein and fiber intake was higher in C1 pre and post-intervention. Empty calories actually started slightly higher in C1, but decreased to a lower value at the end of the intervention in C1 (997.6 ± 948.1 and 441.6 ± 240.1 calories in C1 vs. 964.3 ± 689.4 and 627.1 ± 449.8 calories in C2). Fruit and vegetable intake had a group by diet interaction (p= 0.043), with C1 maintaining a higher fruit and vegetable intake at both pre-intervention and post-intervention (2.5 ± 2.0 and 5.2 ± 2.4 cups/day respectively), whereas C1 intake was 1.7 ± 1.5 and 4.6 ± 1.5 cups/day, respectively.

Conclusions: Both cohorts improved in dietary intake by the 8-week free-living dietary intervention. However, young adults with MetS had lower overall dietary quality in comparison to the healthy cohort before and after the intervention suggesting those with lower diet quality beginning the intervention with MetS may require longer dietary interventions to yield similar dietary improvements to result in better metabolic health.
