Skin Carotenoids Measured by Reflection Spectroscopy Correlates with Vegetable Intake Frequency in Adolescents of Racial and Ethnic Minorities in Houston, Texas.
Objective methods are needed to assess adolescent fruit and vegetable (F/V) intake to better evaluate interventions aimed at improving F/V intake. Skin carotenoid concentration measures provide a potential objective biomarker of F/V intake, but the plausibility and robustness must be established acr...

Skin carotenoid concentration measures provide a potential objective biomarker of F/V intake, but the plausibility and robustness must be established across adolescent populations. The objective of this study is to evaluate the relationship between pressure-mediated reflection spectroscopy-measured skin carotenoid scores (SCSs) and self-reported F/V intake frequency among US racial and ethnic minority adolescents in Houston, TX. This is a secondary analysis of data collected on adolescents participating in the randomized, controlled study Teens Committed to Health Through Activity, Relationships, and Good Eating. Participants were Hispanic (86.2%), African American (12.6%), and Asian (1.2%) adolescents (age 10 to 17 years) (N = 167) who participated in a year-long healthy lifestyles program as their physical education class in Houston, TX, from August 2018 to 2019. Over the course of a year, participants' SCSs were measured by pressure-mediated reflection spectroscopy, and self-reported F/V intake frequency was assessed using questions from the School Physical Activity and Nutrition questionnaire at 4 separate time points. The relationship between adolescent SCSs and F/V intake frequency was tested using generalized linear mixed models, controlling for body mass index z score, sex, time point, group assignment, and age. SCSs were positively predicted by self-reported intake frequencies for F/V (β = 2.398; P =.028), vegetables (β = 3.870; P =.010), and orange and dark green vegetables (β = 5.274; P =.019), with no significant relationship observed with fruit intake frequency (β = 1.151; P =.613). Self-reported total F/V (combined), vegetable, and orange and green vegetable (combined) intake frequency is a predictor of SCSs among racial and ethnic minority adolescents in Houston, TX. Skin carotenoid measurement merits further investigation as a biomarker of vegetable intake in US adolescents. pubtype: Academic Journal doctype: research randomized controlled trial Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
