Transitioning to university involves several changes, which might affect dietary habits. The present study aimed to assess the potential relationships involving adherence to the MedDiet, body composition, and metabolic markers within a Portuguese university sample.
A cross-sectional study involved 70 participants, 52 women, and 18 men (23.00 ± 7.00 years old and a BMI of 21.99 ± 2.79 kg/m). The average MedDiet adherence of participants was 9.23 points, as evaluated by the 14 point validated questionnaire, with classifications of low and high (under or over 9 points, respectively). Body composition was assessed using X-ray dual densitometry (DXA), and metabolic markers were collected from capillary blood.
Statistically significant differences in HDL cholesterol and the total/HDL cholesterol ratio were found between groups. Lower levels ( < 0.05) of visceral (VAT) and subcutaneous adipose tissue (SAT), BMI, and waist circumference were found in the higher MedDiet adherence group. Those measures were negatively correlated ( < 0.05) with the adherence scores to the MedDiet.
Higher adherence to MedDiet seemed to have a favorable and important impact on lipid profiles, primarily HDL-c. A positive relationship between MedDiet adherence and body composition distribution was also described, mostly due to the influence of higher adherence to MedDiet at lower levels of VAT and SAT in Portuguese university students.
进入大学涉及到多种变化,这可能会影响饮食习惯。本研究旨在评估在葡萄牙大学生样本中,涉及到坚持地中海饮食、身体成分和代谢标志物的潜在关系。
一项横断面研究涉及 70 名参与者,其中 52 名女性和 18 名男性(年龄 23.00 ± 7.00 岁,BMI 为 21.99 ± 2.79kg/m²)。参与者平均地中海饮食依从性评分为 9.23 分,采用 14 分验证问卷进行评估,分为低(<9 分)和高(>9 分)两组。身体成分采用 X 射线双能 X 线吸收法(DXA)进行评估,代谢标志物采用毛细血管血采集。
两组间 HDL 胆固醇和总/HDL 胆固醇比值存在统计学显著差异。在高地中海饮食依从性组中,发现更低水平(<0.05)的内脏(VAT)和皮下脂肪组织(SAT)、BMI 和腰围。这些指标与地中海饮食依从性评分呈负相关(<0.05)。
更高的地中海饮食依从性似乎对血脂谱有有利且重要的影响,主要是对 HDL-c。还描述了地中海饮食依从性与身体成分分布之间的正相关关系,这主要归因于在葡萄牙大学生中,地中海饮食依从性更高,导致 VAT 和 SAT 水平更低。
