Weight gain during the menopausal transition is common. Although studies have suggested that weight gain is more likely related to aging than menopause, there is a reduction in resting energy expenditure with surgical or natural menopause which is independent of age and changes in body composition. The underlying mechanisms could include a reduction in core body temperature.
Data were obtained from two related studies. Sample size was 23 men and 25 women (12 premenopausal,13 postmenopausal). In the Clinical Research Unit, core temperature was measured every minute for 24 hours (CorTemp System,HQ Inc.).
Mean 24-hour core body temperature was 0.25 ± 0.06 °C lower in postmenopausal than premenopausal women (p=0.001). Mean 24-hour core temperature was 0.34 ± 0.05 °C lower in men than in premenopausal women (p<0.001).
Postmenopausal women, like men, had lower core body temperatures than premenopausal women. This may have implications for midlife weight gain.
绝经过渡期间体重增加很常见。尽管研究表明体重增加更可能与衰老而非绝经有关，但手术绝经或自然绝经后静息能量消耗会减少，这与年龄和身体成分变化无关。其潜在机制可能包括核心体温降低。
数据来自两项相关研究。样本包括23名男性和25名女性（12名绝经前女性，13名绝经后女性）。在临床研究室，使用CorTemp系统（HQ公司）每分钟测量一次核心体温，持续24小时。
绝经后女性的24小时平均核心体温比绝经前女性低0.25±0.06°C（p = 0.001）。男性的24小时平均核心体温比绝经前女性低0.34±0.05°C（p<0.001）。
绝经后女性与男性一样，核心体温低于绝经前女性。这可能对中年体重增加有影响。
