Abstract

Our objective was to correlate body mass index (BMI) with mid-arm circumference (MAC) and also to ascertain whether maternal BMI could be calculated from MAC at booking. We approached all Caucasian women who met the inclusion criteria attending the University College Hospital, London between 1 April 1996 and 30 June 1997 and the Rotunda Hospital, Dublin, Ireland between 15 April 2003 and 19 May 2004. A total of 2,912 women agreed to participate in the research. The participants' maternal height and weight were measured. Their BMI was calculated using the formula: BMI = weight (kg) ÷ height (m(2)). The MAC was measured in cm. Statistical analysis was performed using SPSS for Windows version 11 with p < 0.05 as significant. We found that BMI is directly correlated with MAC (r = 0.836) and estimates of BMI may be calculated from the simple equation BMI = MAC ± 2. Alternatively, a MAC of ≥ 27 cm allowed for a detection rate for overweight patients of 75%, with a false positive rate of 15%.

摘要

我们的目标是将体重指数（BMI）与上臂围（MAC）进行关联，同时确定在初次产检时能否根据MAC计算出孕妇的BMI。我们对符合纳入标准的所有白人女性进行了研究，这些女性在1996年4月1日至1997年6月30日期间就诊于伦敦大学学院医院，以及在2003年4月15日至2004年5月19日期间就诊于爱尔兰都柏林的罗通达医院。共有2912名女性同意参与该研究。测量了参与者的孕母身高和体重。使用公式BMI =体重（千克）÷身高（米²）计算她们的BMI。MAC以厘米为单位进行测量。使用SPSS for Windows版本11进行统计分析，以p < 0.05为具有统计学意义。我们发现BMI与MAC直接相关（r = 0.836），并且BMI的估计值可以通过简单方程BMI = MAC ± 2计算得出。或者，MAC≥27厘米时，超重患者的检出率为75%，假阳性率为15%。
