我们使用一个大型社交媒体数据库Yahoo Answers，探索了一个在线论坛的帖子，其中发帖者询问他们的身高和体重是否符合“瘦”，“瘦”，“胖”或“肥胖”随着时间的推移和论坛主题。我们利用这些数据来更好地了解一个人所在国家高于平均水平的身体质量指数（BMI）是否可能在某些方面保护一个人的身心健康。例如，我们探讨了一个县的肥胖者比例越高是否预示着欺凌行为水平越低，或者“我胖吗？”从那些相对于他/她的实际BMI的正常BMI的问题。大多数问自己是否肥胖的女性实际上并不肥胖。实际超重/肥胖的男性和女性在未来更有可能寻求关于欺凌的建议，而不是瘦的人。此外，随着平均县级BMI的增加，欺凌减少，然后再次增加（U形曲线）。不管他们住在哪里，那些问“我胖吗？”BMI在健康范围内的人比其他发帖者更有可能随后发布健康问题，但随着县级BMI的增加，此类发帖者的比例也大幅下降。我们的研究结果表明，居住在BMI水平较高的县的肥胖者可能比居住在BMI水平较低的县的肥胖者的身体和心理健康状况更好，但这些改善是适度的。
Using a large social media database, Yahoo Answers, we explored postings to an online forum in which posters asked whether their height and weight qualify themselves as “skinny,” “thin,” “fat,” or “obese” over time and across forum topics. We used these data to better understand whether a higher-than-average body mass index (BMI) in one’s county might, in some ways, be protective for one’s mental and physical health. For instance, we explored whether higher proportions of obese people in one’s county predicts lower levels of bullying or “am I fat?” questions from those with a normal BMI relative to his/her actual BMI. Most women asking whether they were themselves fat/obese were not actually fat/obese. Both men and women who were actually overweight/obese were significantly more likely in the future to ask for advice about bullying than thinner individuals. Moreover, as mean county-level BMI increased, bullying decreased and then increased again (in a U-shape curve). Regardless of where they lived, posters who asked “am I fat?” who had a BMI in the healthy range were more likely than other posters to subsequently post on health problems, but the proportions of such posters also declined greatly as county-level BMI increased. Our findings suggest that obese people residing in counties with higher levels of BMI may have better physical and mental health than obese people living in counties with lower levels of BMI by some measures, but these improvements are modest.
