Short Video Viewing & Obesity
While previous studies have associated sedentary time (ST) and overweightness/obesity, the type of sedentary behavior is still unclear. Nowadays, short video viewing is one of the more popular leisure sedentary behavior. However, the association between short video viewing and overweightness/obesity remains to be determined.
A recently published cross-sectional study on 1105 older women aged 60-70 years examined the associations between short video viewing and overweightness/obesity in Chinese community-dwelling older women. It reported that a higher short video viewing time was associated with a higher body mass index. Interestingly, when compared with non-food short videos, short food videos had a greater effect on overweightness/obesity. The authors suggested that a reduction in short video viewing, especially the food category, might be an effective way to prevent overweightness/obesity when incorporated in future public health policy.
On reflection, I am spending significant sedentary hours watching YouTube and TikTok videos. I may need to moderate my sedentary activity and level. A timely reminder.
