研究人员对 5 名住院、病情稳定、胎龄 30 至 34 周、产后 5 至 10 天的早产儿的体温生物节律进行了研究。腹部皮肤温度以及培养箱空气温度由热敏电阻测量，并使用计算机数据采集系统在全天 24 小时内以一分钟的间隔进行记录。使用自相关（时间序列分析的一种形式）对数据进行分析。在五名受试者中的三名中观察到温度的循环模式。周期的时间长度为两小时、三小时和六小时。培养箱的空气温度没有表现出类似的周期性，因此假设培养箱的运行与观察到的婴儿温度的周期性变化无关。
The biorhythm of body temperature was studied in five hospitalized, medically stable preterm infants, gestational age 30 to 34 weeks and postnatal age 5 to 10 days. Abdominal skin temperature, as well as incubator air temperature, were measured by thermistors and recorded at one-minute intervals throughout a 24-hour day using a computerized data acquisition system. Data were analyzed using autocorrelation, a form of time series analysis. A cyclic pattern of temperature was observed in three of the five subjects. The length of time of the cycles were two, three, and six hours. Incubator air temperature did not exhibit similar cyclicity, and it is therefore assumed that incubator operation is not responsible for the observed cyclic variation in infant temperature.
