| dc.description.abstract | There is a causal link between consuming carbohydrate food sources with anthropometrics and
fat-related body composition in adults, however, there are scarce data investigating the
longitudinal relationship between intake of carbohydrate sources with anthropometrics and body
composition over time in college students. As part of a larger study, 17 students at the University
of Wisconsin-Stout were evaluated over 4 years. Participants filled out a yearly diet history
questionnaire to assess carbohydrates as percent of energy intake, fruit, vegetable, and added
sugar intake. Yearly anthropometrics were collected, including, weight and height for body mass
index calculation, as well as waist circumference. Fat-related body composition measures,
including total body fat percentage and visceral adipose tissue, were measured using serial dualenergy
x-ray absorptiometry scans. A statistically significant difference between the association
of different intakes of carbohydrates with anthropometrics and body fat composition measures
was not established. Although there was a trend toward reduced weight and visceral adipose
tissue with increased fruit intake (weight: -0.54 kg; p<.05; visceral adipose tissue: -0.60 in3,
p<.05) and reduced visceral adipose tissue with increased vegetable intake (visceral adipose
tissue: -0.60 in3, p<.05) in year 1, this was found to clinically insignificant by year 4. Although
our study was underpowered and did not show an association between carbohydrate intake with
anthropometrics and body fat composition, there were promising trends between diet, weight,
and visceral fat composition during the first year that warrant further study and expansion of our
clinical cohort. | en_US |
