Micronutrient deficiency in the diets of para-athletes participating in a sports scholarship program
(Mikronährstoffmangel in der Ernährung von Parasportlern, die an einem Sportstipendienprogramm teilnehmen)
Objectives
The aim of this study was to determine the usual energy and micronutrient intake distributions and compare the prevalence of insufficient/excessive micronutrient intake in Brazilian para-athletes with and without scholarship support.
Methods
The study was conducted between September 2018 and August 2019 and included 101 athletes with a disability from 13 Paralympic disciplines living in Brasília, the Federal District. Food intake was estimated from two or four non-consecutive 24-h food recalls in which para-athletes reported all food, beverages, and supplements consumed in the previous 24-h. Dietary intake analysis was performed by implementing the National Cancer Institute method. Comparisons between scholarship and non-scholarship athletes were performed using Student's t tests for parametric variables and Wilcoxon signed-rank tests for nonparametric variables.
Results
Mean usual energy intake was significantly lower in scholarship para-athletes (2128 ± 125 kcal/d) than in non-scholarship para-athletes (2239 ± 116 kcal/d; P < 0.001). The prevalence of inadequacy for vitamin D, calcium, vitamin A, thiamine, riboflavin, and zinc was significantly higher in scholarship than in non-scholarship para-athletes (P < 0.001). The prevalence of risk for iron deficiency was 29.5% in female para-athletes. The prevalence of micronutrient inadequacy was >10% for eight (60%) and seven (54%) micronutrients among scholarship and non-scholarship para-athletes, respectively.
Conclusions
The Brazilian Federal sport scholarship assistance program in its current format is insufficient to protect athletes from micronutrient inadequacies.
Highlights
• Micronutrient deficiency in the diets of para-athletes.
• There was a high prevalence of inadequacy for most micronutrients both among scholarship and non-scholarship para-athletes.
• Assessment of micronutrient in para-athletes was performed with rigours and adequate methodology.
