摘要
目的随着年龄的增长，身体成分也会发生变化，瘦体重会逐渐减少，而胖体重则会逐渐增加。维生素 A 的摄入量和状况可能会影响年轻人的脂肪含量。然而，巴西老年人维生素摄入不足的比例很高。本研究旨在分析社区中老年人通常的维生素 A 摄入量与身体组成之间的关系。对他们进行了人体测量评估（体重、身高、腰围和小腿围），通过生物电阻抗对身体成分进行了评估，并通过 24 小时回忆对食物摄入量进行了评估。维生素 A 的摄入量（μg/R.A.E）与老年人的身体成分没有相关性。除维生素 B6 和钙、镁、钠、钾、铜和硒等矿物质（80%）外，还发现维生素 A 摄入量不足（90%）。
Vitamin A intake and body composition in community-dwelling older adults
Objective
Aging brings changes in body composition that involve the gradual loss of lean mass and increase in fat mass. Vitamin A intake and status might influence adiposity in young people. However, the Brazilian elderly have a high prevalence of inadequate intake of this vitamin. The aim of this study was to analyze the relationship between the usual intake of vitamin A and the body composition of the elderly in the community.
Methods
This is a cross-sectional study carried out with men and women aged equal or over 60 years who actively participate in the community. Anthropometric assessments were performed (weight, height, waist and calf circumference), body composition assessment by bioelectrical impedance, and food intake assessment using a 24-hour recall.
Results
About 88.7% of the sample were above the adequate percentage of body fat. No correlation was found between the intake of vitamin A (μg/R.A.E) and a body composition of the elderly. Inadequate consumption of vitamins A (> 90%), in addition to vitamin B6 and minerals such as calcium, magnesium, sodium, potassium, copper and selenium (> 80%), was also observed.
Conclusion
A high inadequacy of dietary intake of vitamin A was found in the elderly, which might be associated with excessive body fat indices in the studied sample.
