背景：Covid-19疫情期間，為防止病毒傳播而實施的防疫政策（例如：社交距離、居家隔離與封城）大大地打亂了人們的日常生活。過去研究發現，年輕人久坐的時間及遊玩遊戲的程度有顯著地提升。此外，年輕人也更加擔心自身體重狀態與知覺體重汙名的問題。證據顯示，久坐時間、過度遊戲與知覺體重汙名皆和健康存在負向關係（例如：壓力、憂鬱、飲食障礙、低體力活動量）。也有證據顯示在Covid-19疫情期間，年輕人有久坐、高度遊戲使用及知覺體重汙名等現象。因此，本研究合理推斷在Covid-19疫情期間，年輕人的久坐時間、遊戲使用和知覺體重汙名之間可能存在關聯。目的：本研究旨在調查台灣年輕人在Covid-19疫情期間的坐姿時間、過度遊戲、體重狀況和知覺體重汙名之間的關係。此外，本研究探討體重狀況與知覺體重汙名是否為坐姿時間與過度遊戲間的中介變項。方法：本橫斷研究以線上方式進行，從台灣的大學招募參與者。使用便利抽樣招募參與者（n = 600），完成人口學變項問卷（包含體重與身高）和自陳式量表，包含國際體力活動問卷短版（IPAQ-SF）、知覺體重汙名量表（PWSS）以及網路遊戲障礙量表短版（IGDS9-SF）本研究使用的統計分析包括描述性統計、獨立樣本t檢定、相關分析、Hayes中介分析（Hayes’ Process Model）。結果：本研究結果發現，久坐時間與過度遊戲、體重狀況與知覺體重汙名之間有顯著負相關。體重狀況和知覺體重汙名為久坐時間與過度遊戲的中介變項，此外，久坐時間與過度遊戲存在雙向影響的關係。結論：受到Covid-19疫情的影響，本研究發現了行為上的改變（例如：較少的坐姿時間、高遊戲使用、高知覺體重汙名）且這些變化與健康呈現負向關係。預防措施應專注於提供降低久坐時間、降低過度遊戲及降低體重汙名等方面的資訊。

Background: The impact of Covid-19 pandemic has greatly disturbed people’s daily life due to the restrictions (e.g., social distancing, home confinement, and lockdowns) to prevent the virus spreading. Previous studies found that there were significantly prolonged sitting time and high levels of gaming use among young adults. Also, young adults are increasingly concerned regarding their weight status and perceived weight stigma (PWS). Moreover, evidence showed that prolonged sitting time, excessive gaming and PWS were related to negative health consequences (e.g., stress, depression, eating disturbances, low level of engagement in physical activity). Additionally, evidence showed that there was high level of sitting time, gaming use, PWS among young adults during Covid-19 pandemic. Therefore, it would be possible that there were association between prolonged sitting time, gaming use, PWS, and weight status among young adults during Covid-19 pandemic. Objective: This research sought to investigate the link between time spent sitting, excessive gaming, weight status and PWS among young adults in Taiwan during the time of Covid-19 pandemic. Furthermore, this study investigated weight stigma and PWS as mediators of the relationship between prolonged sitting time and excessive gaming. Methods: The cross-sectional study was conducted via survey online from Taiwan universities. The participants (n = 600) were recruited using convenience sampling and completed demographic questionnaire (including self-report weight and height) and self-report measures including International Physical Activity Questionnaire Short Form (IPAQ-SF), the Perceived Weight Stigma Scale (PWSS), and the Internet Gaming Disorder Scale-Short Form (IGDS9-SF). The statistical analyses used in the present study included descriptive statistics, independent t-test, correlation analysis, and Hayes’ Process Model for mediation analyses. Results: The findings showed a strong and negative correlation between prolonged sitting time with excessive gaming, weight status and PWS. Weight status and PWS were role of the association between prolong sitting time and excessive gaming. Additionally, there were bidirectional effects between time spent sitting and excessive gaming. Conclusion: The present study showed that behaviors changed (i.e., less sitting time, higher gaming use, and higher PWS) due to the impact of the Covid-19 pandemic, and these changed behaviors were related to negative health outcomes. Prevention efforts should focus on providing information to reduce prolonged sitting time, excessive gaming and PWS among young adults.
