We used data from a population-based study of 9,039 adolescent and young adult females, followed prospectively since 1996 as part of the Growing Up Today Study (GUTS), to examine the relationship between season of birth and disordered eating in the U.S.
We tested whether the distribution of birth season and month differed for participants who had ever reported both underweight and dieting/weight concern symptoms (n = 134) or both frequent bingeing and purging symptoms (n = 77) compared with other GUTS participants.
The two disordered-eating groups had relative birth peaks in the fall and relative birth troughs in the summer compared with other GUTS participants, but only the fall peak was consistently statistically significant.
It appears that U.S. females born in the fall are more likely to develop disordered eating and that age relative to the rest of their school-year cohort may account for some of this phenomenon.
我们利用了一项基于人群的研究数据，该研究共纳入了 9039 名青少年和年轻成年女性，这些女性自 1996 年起作为“今日成长研究”（GUTS）的一部分进行前瞻性随访。我们旨在研究出生季节与美国饮食失调之间的关系。
我们测试了在 GUTS 参与者中，那些既报告过体重过轻和节食/体重担忧症状（n=134），又报告过频繁暴食和催吐症状（n=77）的参与者的出生季节和月份分布是否与其他 GUTS 参与者不同。
与其他 GUTS 参与者相比，这两个饮食失调组的相对出生高峰出现在秋季，相对出生低谷出现在夏季，但只有秋季高峰始终具有统计学意义。
似乎美国秋季出生的女性更容易出现饮食失调，而与同龄人相比的年龄可能是造成这种现象的部分原因。
