The month of diagnosis of hyperthyroidism in 183 patients from the area of Wellington, for the period 1977-1986 was ascertained. A significantly greater proportion of cases (58%, p less than 0.05) were diagnosed in the warmer period of the year (November to April) than in the cooler period (May to October). Although seasonal environmental factors, such as changes in iodine intake; or other unrecognised factors, such as differences among the patients themselves, may possibly play an aetiological or pathogenetic role, the significantly greater proportion of thyrotoxic patients diagnosed during the warmer 6-month period of the year is presently best explained by the fact that symptoms tend to be less tolerable in warm weather.
确定了1977年至1986年期间惠灵顿地区183例甲状腺功能亢进患者的诊断月份。与较凉爽时期（5月至10月）相比，一年中较温暖时期（11月至4月）诊断出的病例比例显著更高（58%，p<0.05）。尽管季节性环境因素，如碘摄入量的变化；或其他未被认识的因素，如患者自身的差异，可能在病因学或发病机制中起作用，但目前，一年中较温暖的6个月期间诊断出的甲状腺毒症患者比例显著更高，最好的解释是在温暖天气下症状往往更难以忍受。
