Although physical activity has many health benefits, 45.8% of U.S. adults did not meet the WHO recommendation in 2018. Delivering health-related content, particularly physical activity, through YouTube may help to overcome some barriers, such as lack of access to resources. This study aimed to examine the association between watching health-related information on YouTube and increased levels of physical activity among U.S. adults.
Using the U.S. national cross-sectional survey-Health Information National Trends Survey 2020 (=3,865), we conducted a multivariable logistic regression on obtaining 150 minutes of at least moderate-intensity physical activity per week (WHO guidelines) by watching health-related information on YouTube, controlling for demographics (age, sex, race/ethnicity), socioeconomics (income, education level, insurance coverage, employment), current use of cigarettes and e-cigarettes, use of electronic wearable devices (e.g., Fitbit), self-reported health status, BMI, and the presence of chronic conditions (e.g., diabetes, heart disease, cancer) and depression or anxiety disorders.
Overall, 40.8% (weighted) of respondents reported using YouTube to watch health-related videos, and 39.2% reported meeting the WHO-recommended physical activity level. After controlling for covariates, adults who reported watching health-related videos on YouTube in the past 12 months (versus not watching) were 1.33 times more likely to do 150 minutes or more of moderate physical activity a week (AOR=1.33; 95% CI=1.01, 1.76).
This study suggests that adults who view health-related YouTube videos may be more likely to meet the WHO-recommended level of physical activity. This finding could inform future behavioral interventions using online video platforms to promote physical activity.
尽管体育活动对健康有诸多益处，但2018年美国有45.8%的成年人未达到世界卫生组织的建议标准。通过YouTube提供与健康相关的内容，尤其是体育活动方面的内容，可能有助于克服一些障碍，比如获取资源困难。本研究旨在调查在美国成年人中，观看YouTube上与健康相关的信息和体育活动水平提高之间的关联。
我们利用美国全国横断面调查——2020年健康信息国家趋势调查（n = 3865），针对通过观看YouTube上与健康相关的信息，每周进行至少150分钟中等强度体育活动（符合世界卫生组织指南）的情况进行多变量逻辑回归分析，同时控制人口统计学因素（年龄、性别、种族/族裔）、社会经济因素（收入、教育水平、保险覆盖情况、就业状况）、当前香烟和电子烟使用情况、电子可穿戴设备（如Fitbit）的使用情况、自我报告的健康状况、体重指数以及慢性病（如糖尿病、心脏病、癌症）和抑郁或焦虑症的存在情况。
总体而言，40.8%（加权）的受访者表示使用YouTube观看与健康相关的视频，39.2%的受访者表示达到了世界卫生组织建议的体育活动水平。在控制协变量后，过去12个月内在YouTube上观看过与健康相关视频的成年人（与未观看者相比）每周进行150分钟或更多中等强度体育活动的可能性高出1.33倍（调整后比值比=1.33；95%置信区间=1.01，1.76）。
本研究表明，观看与健康相关的YouTube视频的成年人可能更有可能达到世界卫生组织建议的体育活动水平。这一发现可为未来利用在线视频平台促进体育活动的行为干预提供参考。
