In infants, sleeping metabolic rate (SMR) is used as a proxy for basal metabolic rate (BMR). BMR can be predicted from anthropometry using published equations. Our study was intended to evaluate the ability of these equations to predict measured SMR in infants aged 6 weeks to 12 months. SMR was measured in a mixed longitudinal study using the Douglas bag technique (n = 105). Measured SMR values were compared with BMR predicted from weight (BMR-1) or weight and length (BMR-2). These equations were not successful in predicting SMR in this age group. Percentage error of predicted BMR was related to infant weight (BMR-1: r = 0.26; p < 0.005; BMR-2: r = 0.18; p < 0.06). Alternative logarithmic equations were derived from this study (R = 0.84-0.87; SEE = 0.159-0.168). We conclude that the new equations, relating to contemporary infants, are more suitable but actual measurements remain preferred.
在婴儿中,睡眠代谢率(SMR)被用作基础代谢率(BMR)的替代指标。BMR可使用已发表的公式通过人体测量学来预测。我们的研究旨在评估这些公式预测6周龄至12月龄婴儿测量的SMR的能力。在一项混合纵向研究中,使用道格拉斯袋技术测量了SMR(n = 105)。将测量的SMR值与根据体重(BMR-1)或体重和身长(BMR-2)预测的BMR进行比较。这些公式未能成功预测该年龄组的SMR。预测BMR的百分比误差与婴儿体重相关(BMR-1:r = 0.26;p < 0.005;BMR-2:r = 0.18;p < 0.06)。本研究推导了替代对数方程(R = 0.84 - 0.87;SEE = 0.159 - 0.168)。我们得出结论,与当代婴儿相关的新方程更合适,但实际测量仍然是首选。
