While women with anorexia nervosa are more likely to be born in March through June (in the northern hemisphere), there is no coherent model that explains this association. This study examined the birth pattern of adult restrictive and binge-purge anorexics and whether environmental temperature at assumed conception is a relevant factor. Retrospective analysis of the case notes of 195 adult anorexics was used to determine diagnosis, date of birth, eating attitudes, and body mass index. Meteorological records were used to determine temperature at assumed point of conception. Restrictive anorexics were significantly more likely than binge-purge anorexics to be born in April through June (, conceived July through September). A higher environmental temperature at the point of assumed conception was more likely to be found in restrictive anorexics than in anorexics of the binge-purge subtype. A higher environmental temperature at the assumed point of conception was associated with more restrictive eating attitudes during adulthood, but only among the restrictive anorexics. Possible explanations and implications of these findings are discussed.
虽然神经性厌食症女性在北半球更有可能出生于3月至6月，但尚无连贯的模型来解释这种关联。本研究调查了成年限制型和暴饮暴食清除型厌食症患者的出生模式，以及假定受孕时的环境温度是否为相关因素。对195名成年厌食症患者的病历进行回顾性分析，以确定诊断、出生日期、饮食态度和体重指数。利用气象记录确定假定受孕点的温度。限制型厌食症患者比暴饮暴食清除型厌食症患者在4月至6月出生（假定受孕时间为7月至9月）的可能性显著更高。在限制型厌食症患者中，比在暴饮暴食清除型厌食症患者中更有可能发现假定受孕点的环境温度更高。假定受孕点的环境温度较高与成年期更严格的饮食态度相关，但仅在限制型厌食症患者中如此。讨论了这些发现的可能解释和意义。
