■饮食质量与心理生物学有关,心理,生物,和个体的生理因素,在长期压力的背景下,例如COVID-19大流行,它会导致大学生的食物质量恶化。本研究旨在分析巴西大学生的饮食质量及其相关因素。
■数据来自巴西所有地区的4,799名本科生,从2020年8月到2021年2月。在线问卷包含社会经济变量,ESQUADA量表评估饮食质量,自我参考的体重变化,巴西粮食不安全量表(EBIA),睡眠评估和感知压力量表。进行了非条件多元逻辑回归分析,以研究与不良和极不良饮食质量相关的变量。
■大多数参与者表现出良好的饮食质量(51.7%),而9.8%的人饮食质量差或非常差,只有1.1%的人饮食质量优异。58.2%的本科生报告在大流行期间体重增加,74.3%的学生在大流行期间压力升高。Logistic回归显示,在大流行期间体重增加的学生表现出最高的AOR=1.56(95%CI=1.12-2.20),原因是饮食质量差或非常差。对于不良或非常差的饮食质量,感知压力升高也与较高的AOR=2.85(95%CI=1.71-4.74)相关。
■大多数被研究的本科生表现出良好的饮食质量。然而,不良/非常不良的饮食质量与较高的感知压力和体重增加相关。我们的研究表明,政策应该针对社会经济上最脆弱的大学生,那些处于食物和营养不安全状况的人,高感知压力,以及在大流行期间体重增加的人。
UNASSIGNED: Diet quality is associated with psychobiological, psychological, biological, and physiological factors of individuals, and in the context of prolonged stress, such as the COVID-19 pandemic, it can lead to a worsening of the quality of food for undergraduates. This study aimed to analyze diet quality and associated factors in Brazilian undergraduates.
UNASSIGNED: Data were collected from 4,799 undergraduate students from all Brazilian regions, from August 2020 to February 2021. The online questionnaire contained socioeconomic variables, the ESQUADA scale to assess diet quality, self-referred changes in weight, the Brazilian food insecurity scale (EBIA), sleep assessment and the perceived stress scale. Unconditional multiple logistic regression analysis was performed to study variables associated with poor and very poor diet quality.
UNASSIGNED: Most of participants presented a good diet quality (51.7%), while 9.8% had a poor or very poor diet quality and only 1.1% had an excellent diet quality. 58.2% of undergraduates reported to have an increase in weight during the pandemic and 74.3% of the students presented elevated stress during the pandemic. Logistic regressions showed students who gained weight during the pandemic presented the highest AOR = 1.56 (95% CI = 1.12-2.20) for poor or very poor diet quality. The elevated perceived stress was also associated with a higher AOR = 2.85 (95% CI = 1.71-4.74) for poor or very poor diet quality.
UNASSIGNED: Most of the studied undergraduates presented a good diet quality. Nevertheless, poor/very poor diet quality was associated with higher perceived stress and weight gain. Our study indicated that policies should beaimed at the socioeconomically most vulnerable undergraduates, those in a situation of food and nutritional insecurity, high perceived stress, and who gained weight during the pandemic.
