RESUMO
This study examined the relationship between weight stigma and disordered eating behaviors in university students during the COVID-19 pandemic, considering individuals with and without overweight. A national sample of 738 college students completed an online questionnaire at three time points between July 2020 and December 2021, reporting their experiences of weight stigma, perceived increase in weight stigma during the pandemic, internalized weight stigma, and disordered eating behaviors. The findings showed that the trajectories of disordered eating behaviors varied depending on participants' anthropometric status. Among those with overweight, there was a decrease over time in binge eating, food restriction, and purging. Conversely, the non-overweight group experienced a slight increase in binge eating from T2 to T3. Using the Generalized Estimating Equations model, the study revealed that weight stigma predicted disordered eating behaviors in both weight spectrums during the pandemic. Experiences of weight stigma and the perceived increase in weight stigma significantly increased the likelihood of engaging in binge eating, food restriction, and purging among individuals with overweight. Furthermore, the internalization of weight stigma was longitudinally associated with all examined eating behaviors, regardless of anthropometric status. These findings highlight the importance of addressing weight stigma to prevent disordered eating in college students.

OBJECTIVES: The purpose of this study is to investigate whether the relationship between weight stigma experiences and disordered eating behaviors during the COVID-19 pandemic is mediated by weight gain concern and psychological distress among university students with and without overweight. METHODS: A cross-sectional study was conducted with university students from five regions of Brazil who participated in the baseline assessment of the Online Cohort on Eating Behavior and Health (July/August 2020). Information on the frequency of binge eating episodes, food restriction, and purging, as well as experienced weight stigma, weight gain concern, and psychological distress, were recorded in an online questionnaire. Stratified structural equation modeling (SEM) analyses were performed to address the research questions of interest. RESULTS: Out of the total sample (n = 2511), 33.5% of participants reported experiencing weight stigma. The prevalence of binge eating episodes, food restriction, and purging was 43.7%, 24.1%, and 5.4%, respectively. These behaviors were more prevalent in individuals with overweight than in those without this condition. Furthermore, it was observed that weight gain concern and psychological distress mediated the relationship between weight stigma and disordered eating behaviors regardless of body weight status. CONCLUSIONS: Experiences of weight stigma and disordered eating behaviors were prevalent among Brazilian university students, especially among those with overweight. Weight gain concern and psychological distress appear to be important factors underlying the relationship between these constructs during the pandemic, and they can contribute to the development of targeted strategies for the prevention and management of disordered eating. LEVEL OF EVIDENCE: Level V, cross-sectional study.

Aiming at assessing the quality of oils and fats employed for frying food in bars, restaurants and snack bars, 180 samples were analyzed, from which 90 were collected before use and 90 after the frying process. A questionnaire was used in order to collect information on food frying procedures and on the respective food-serving places infrastructure. The analysis on alterations in oil and fat samples was performed by using the following analytical methods: total polar compounds (%), free fatty acid (mg KOH/g) and peroxide index (meq/kg). Among the 90 samples collected before the frying procedure, 18.18% showed higher values of polar compounds over the established limit (5%), predominantly in samples collected from snack bars. In 7.78%, 12.22% and 2.22% of the analyzed frying oil and fat samples, the total polar compounds, free fatty acids and peroxide indices, respectively, were in a higher rate than those limit values established for discarding them. The inadequacy on the employed frying procedure was observed as this process was performed without control over the frying temperature, type of oil, and employed equipment. These findings indicate that the food-service locations require close surveillance supervisions.
Com o objetivo de avaliar a qualidade de óleos e/ou gorduras utilizados para fritura por imersão em bares, restaurantes e lanchonetes, foram coletadas 180 amostras de óleo e/ou gordura, sendo 90 antes e 90 após fritura. Aplicou-se um questionário para avaliar as técnicas de fritura e a infraestrutura dos estabelecimentos. Foram realizados os métodos analíticos para avaliar a alteração dos óleos e gorduras a saber, compostos polares totais (%), acidez (mg KOH/g) e índice de peróxido (mEq/kg). Das 90 amostras coletadas antes da fritura, 18,18% demonstraram valores de compostos polares superiores ao limite estabelecido (5%), predominantemente nas amostras coletadas em lanchonetes. Quanto aos compostos polares totais, acidez e índice de peróxidos para óleos e gordura de fritura, 7,78%, 12,22% e 2,22% das amostras, respectivamente, apresentaram valores acima dos limites estabelecidos para efetuar o descarte. A avaliação das técnicas de fritura demonstrou dados insatisfatórios, tais como falta de controle da temperatura, tipo de óleo e equipamentos empregados. Os resultados obtidos indicam a necessidade de ações educativas no setor, assim como efetiva fiscalização por parte dos órgãos competentes.
