The Impact of Social Media on Dietary Behaviors and Body Image of College Students: A Qualitative Approach

Food and Nutrition Sciences 2024年第8期15卷 711-726页

作者： Basem Azmy Saad Boutros Tabbetha D. lopez Valencia Browning-Keen Department of Human Sciences Sam Houston State University Huntsville TX USA

Background: The use of social media platforms for health and nutrition information has become popular among college students. Although social media made information readily accessible in different formats, nutritional misinformation promoted by influencers and non-experts caused negative impact on diet behavior and perception of body image. Previous research indicated that extensive use of social media was positively linked to disordered eating behaviors. Social media platforms like Facebook and Instagram that allow users to follow celebrities intensified exposure to influencers’ messages and images and resulted in negative moods and body dissatisfaction. Objective: This paper aims to explore the impact of social media on college students’ dietary behaviors and body image. Participants: 18 undergraduate students from a public university in the Southern United States were recruited through a mass email. Methods: A cross-sectional qualitative study of three focus groups was conducted. The focus groups were based on guiding open-ended questions. *** was used to code and analyze the data using inductive and deductive codes. Results: Three main themes were identified. The conditions theme included elements that explain why and how social media influences the participants’ actions. The actions theme included eating behavior, physical activity, and dietary supplement intake. The consequences theme describes anticipated or actual outcomes of actions such as body image and ideal weight. Conclusions: Social media has had a negative influence on diet behaviors and a positive influence on physical activity. Evidence-based nutrition and weight management information is needed to thwart potential misinformation.

原发于纵隔的性腺外精原细胞瘤比较少见,占该部位所有肿瘤的3%~4%。由于纵隔精原细胞瘤对放疗和/或顺铂为主的化疗特别有效,因此准确诊断对估计预后和指导临床治疗非常重要。尽管最近研究发现OCT4对性腺精原细胞瘤的诊断非常有价值,但已有的研究发现纵隔和睾丸的精原细胞瘤在遗传和免疫表型上是有差异的,导致该抗体是否可作为纵隔精原细胞瘤的诊断标记。为了研究OCT4在纵隔精原细胞瘤中的诊断价值,作者对23例纵隔精原细胞瘤进行了形态学、免疫组化特征和染色体12p的检测。男性22例,女性1例,年龄15~51岁(平均32岁)。20例(87%)为单纯性精原细胞瘤,3例(13%)为混合型生殖细胞肿瘤。形态学上所有病例均有淋巴细胞浸润,其他组织学特征分别为纤维性间隔/间质21例(91%)、肿瘤细胞核仁明显21例(91%)、肿瘤细胞胞质透亮20例(87%)、细胞边界清楚20例)(87%)、肉芽肿性炎17例(74%)、细胞多形性10例(43%)、坏死8例(35%)、明显囊性变2例(8%)、细胞间水肿1例(4%)和合体滋养层细胞1例(4%)。核分裂象0~16/10HPF,平均4.4/10HPF。免疫组化所有病例均不同程度表达OCT4,且所...

Comparative Study of the Physicochemical Quality of the Waters of the Méné River (Sassandra Watershed, Ivory Coast) in the Dry Season and in the Rainy Season

引用

Journal of Environmental Protection 2024年第6期15卷 738-746页

作者： Konan lopez Kouamé Gansso Valentin Akilinon Olivier Simon Mananga Kombo Gneneyougo Emile Soro Bi Tié Albert Goula Science and Technology Department Alassane Ouattara University Bouak Ivory Coast Environmental Sciences Laboratory Nangui Abrogoua University Abidjan Ivory Coast

The study carried out on the waters of the Méné River led to an overall assessment of its water quality during the dry season and the rainy season. The analysis focused on eight (8) water samples taken from the river during a period of dry season (January-February) and a period of rainy season (June and September). The various physicochemical parameters were measured according to Afnor standardized methods. The readings of temperature, turbidity, pH and conductivity made it possible to account for the disturbances occurring in water quality. A temporal variation correlated with the seasons (dry or rainy) is noted. Turbidity depends on the concentration of suspended solids (SS) in the water and drained particles and therefore on the seasons. Just like the temperature, the conductivity changes with the season. The waters of the Méné River are generally acidic. The results obtained show that there is a low level of pollution by chlorides, phosphates, nitrites and nitrates. A slight pollution of the waters of Méné in organic matter (chemical oxygen demand values are less than 25 mg∙L−1 during dry season and 32.33 ± 4.73 mg∙L−1 during rainy season) was observed. The concentrations of metallic trace elements such as iron, manganese and aluminum indicate significant pollution of these waters by these elements. Overall, the waters of the Méné River are of satisfactory quality because all the physicochemical parameters analyzed have values below standards during the dry season as well as during the rainy season with the exception of COD and a few metallic trace elements.
