探讨强光治疗是否能降低超重受试者的体重，而不考虑其季节性（=光）依赖性。一项交叉、安慰剂对照、随机临床试验于11月至4月在俄罗斯新西伯利亚（55°N）进行。该试验包括一个为期三周的使用发光二极管装置的早晨强光治疗的家庭阶段和一个为期三周的使用失活离子发生器的安慰剂阶段，中间间隔至少23天的非协议期。安慰剂治疗和轻度治疗的次数与季节相匹配。数据来自34名年龄在20-54岁的超重女性，其中10名根据季节性模式评估问卷（Seasonal Pattern Assessment Questionnaire）有季节性依赖。每周测量包括体重、生物阻抗法测定的体脂百分比和主观评分（食欲、情绪、能量水平）。在两个干预疗程中，减肥的动机和期望是相似的。与安慰剂组相比，轻组的体重没有显著减少，但脂肪百分比、脂肪质量和食欲显著降低（平均脂肪减少0.35公斤）。从分析中排除季节性相关的受试者后，后两个结果仍然显著。无论干预类型如何，季节性依赖的受试者在治疗期间（下降p h h 0.036）或疗程之间（恢复p h h 0.003）有更大的体重和脂肪量变化。光周期（p = 0.0041）、气温（p = 0.012）与体重变化的关系较小，而日照（p = 0.29）与体重变化的关系较小（如果第二阶段是在春季）。晨光治疗可减少超重妇女的体脂和食欲，并可纳入体重控制计划。
To investigate whether bright light treatment can reduce body mass in overweight subjects irrespective of their seasonal (= light) dependence. A crossover, placebo-controlled, randomized clinical trial was performed between November and April in Novosibirsk, Russia (55° N). The trial comprised a 3-week in-home session of morning bright light treatment using a device of light-emitting diodes and a 3-week placebo session by means of a deactivated ion generator, separated by an off-protocol period of at least 23 days. The number of placebo and light sessions was matched with respect to season. Data were obtained from 34 overweight women, aged 20–54 years, 10 were seasonal-dependent according to the Seasonal Pattern Assessment Questionnaire. Weekly measures included body weight, percentage body fat by bioimpedancemetry, and subjective scores (appetite, mood, energy levels). Motivation and expectation towards weight loss were similar for the two intervention sessions. With light, compared to the placebo session, weight did not reduce significantly, but percentage fat, fat mass, and appetite were significantly lower (average fat reduction 0.35 kg). The latter two results remained significant after excluding seasonal-dependent subjects from the analysis. Irrespective of the type of intervention, seasonal-dependent subjects had greater weight and fat mass changes during treatment (decline p ℋ 0.036) or between sessions (regain p ℋ 0.003). Photoperiod (p = 0.0041), air temperature to a lesser extent (p = 0.012), but not sunshine (p = 0.29) was associated with the weight change (greater weight reduction if the second session was in spring). Morning bright light treatment reduces body fat and appetite in overweight women and may be included in weight control programs.
