Abstract：
Physical inactivity represents a global challenge in public health, being the second most significant factor contributing to mortality. In Latin America, the prevalence of physical inactivity and sedentary behaviour is notable, affecting medical students as well, who play a crucial role as behavioural role models for the population. This study addresses the prevalence of physical activity and sedentary behaviour among medical students in Latin America during the year 2023. A total of 864 participants from 12 institutions across eight countries were surveyed using the Global Physical Activity Questionnaire. Significant variations in physical activity and sedentary behaviour were observed according to sex, age, body mass index, academic year, and country. Notably, Costa Rica exhibited the highest levels of moderate physical activity in leisure time (90 min/day). Strength training was more common among men (60 min/day) and in Argentina (60 min/day). Sedentary behaviour was higher in women (420 min/day) and during the first academic year (485 min/day). Uruguay stood out with high levels of sedentary behaviour (600 min/day). Correlations indicated positive moderate associations between academic year and moderate leisure-time PA (r:0,128, p:0,007). In conclusion, there are associations between the level of physical activity and sedentary behaviour with the variables studied in this research, with the main findings being that the female sex has more time spent in sedentary behaviour (minutes/day) and less time spent in strength training (minutes/day). Additionally, there are higher levels of sedentary behaviour in the early years of medical study compared to the later years of the program.
摘要：
缺乏身体活动代表了公共卫生的全球挑战，是导致死亡率的第二重要因素。在拉丁美洲,缺乏身体活动和久坐行为的流行是值得注意的，也会影响医学生，他们作为人口的行为榜样起着至关重要的作用。这项研究针对2023年拉丁美洲医学生的体育锻炼和久坐行为的患病率。使用全球身体活动问卷对来自8个国家12个机构的864名参与者进行了调查。根据性别观察到身体活动和久坐行为的显着变化，年龄,身体质量指数,学年,和国家。值得注意的是,哥斯达黎加在休闲时间（90分钟/天）表现出最高水平的中等体育锻炼。力量训练在男性（60分钟/天）和阿根廷（60分钟/天）中更为常见。女性（420分钟/天）和第一学年（485分钟/天）的久坐行为较高。乌拉圭以高水平的久坐行为(600分钟/天)脱颖而出。相关性表明学年和中等休闲时间PA之间存在正的中度关联（r：0,128，p：0,007）。总之,身体活动水平和久坐行为与本研究中研究的变量之间存在关联，主要发现是，女性在久坐行为上花费的时间更多（分钟/天），而在力量训练上花费的时间更少（分钟/天）。此外,与该计划的后期相比，医学研究早期的久坐行为水平更高。
