Factors associated with body image dissatisfaction in a Brazilian university sample during the COVID-19 pandemic

We investigated the prevalence of body image dissatisfaction (BID) and associated factors among professors and undergraduate students in Brazil during the COVID-19 pandemic. Using Stunkard's Figure Rating Scale, BID was analyzed in a sample of 2,220 adults. The independent variables were sociodemographic, lifestyle, mental health symptoms, COVID-19-related factors, disordered eating, experience of weight stigma, and weight change concerns. We used a multinomial logistic regression analysis. The overall prevalence of BID was 82.5% (69.0% due to excess weight), with more professors dissatisfied by excess weight than undergraduate students (78.9% vs. 61.2%, p < 0.001). In the adjusted model, being a young adult (PR, 1.201, 95% CI: 1.128;1.279), married or in a stable union (PR, 1.088, 95% CI: 1.027;1.152), reporting of binge eating episode (PR, 1.120, 95% CI: 1.068;1.173), concern about weight gain (PR, 1.394, 95% CI: 1.310;1,483), and experience of excess weight stigma (PR, 1.193, 95% CI: 1.141;1.248) increased the prevalence of BID due to excess weight. While males (PR, 1.578, 95% CI: 1.328;1.875), moderate to severe depressive symptoms (PR, 1.217, 95% CI: 1.011;1.465), the concern of losing weight (PR, 1.494, 95% CI: 1.221;1.830), and experience of low weight stigma (PR, 2.620, 95% CI: 2.093;3.280) increased the prevalence of BID due to low weight. Different factors associated with BID were observed between students and professors. Bearing in mind the complexity of body image, it is essential to consider different public health interventions and the COVID-19 pandemic's influence on reducing BID among Brazilian adults, especially susceptible groups.

COVID-19 vaccines effectiveness against symptomatic disease and severe outcomes, 2021-2022: a test-negative case-control study.

OBJECTIVES: This study evaluated the effectiveness of COVID-19 vaccines in preventing symptomatic and severe disease. STUDY DESIGN: This was an observational test-negative case-control study. METHODS: Study participants were adults with at least one symptom included in the World Health Organization COVID-19 definition who sought health care in a public emergency department between 1 November 2021 and 2 March 2022 (corresponding with the fifth pandemic wave in Portugal dominated by the Omicron variant). This study used multivariable logistic regression models to estimate and compare the odds ratio of vaccination between test-positive cases and test-negative controls to calculate the absolute and relative vaccine effectiveness. RESULTS: The study included 1059 individuals (522 cases and 537 controls) with a median age of 56 years and 58% were women. Compared with the effectiveness of the primary vaccination scheme that had been completed ≥180 days earlier, the relative effectiveness against symptomatic infection of a booster administered between 14 and 132 days earlier was 71% (95% confidence interval [CI]: 57%, 81%; P < 0.001). The effectiveness of the primary series against symptomatic infection peaked at 85% (95% CI: 56%, 95%) between 14 and 90 days after the last inoculation and decreased to 34% (95% CI: -43%, 50%) after ≥180 days. CONCLUSIONS: Despite the known immunological evasion characteristics of the Omicron variant, results from this study show that vaccine effectiveness increases after booster administration. COVID-19 vaccine effectiveness decreases to less than 50% between 3 and 6 months after completion of the primary cycle; therefore, this would be an appropriate time to administer a booster to restore immunity.

Conducting Cross-Cultural Research on COVID-19 Memes

A cross-linguistic study of COVID-19 memes should allow scholars and professionals to gain insight into how people engage in socially and politically important issues and how culture has influenced societal responses to the global pandemic. This preliminary study employs framing analysis to examine and compare issues, actors and stances conveyed by both English and Chinese memes. The overall findings point to divergence in the way individuals communicate pandemic-related issues in English-speaking countries versus China, although a few similarities were also identified. 'Regulation' is the most common issue addressed by both English and Chinese memes, though the latter does so at a comparatively higher rate. The 'ordinary people' image within these memes accounts for the largest percentage in both data sets. Although both Chinese and English memes primarily express negative emotions, the former often occurs on an interpersonal level, whereas the latter aims at criticizing society and certain group of people in general. Lastly, this study proposes explanations for these findings in terms of culture and political environment. © 2022 Association for Computational Linguistics.
