ABSTRACT

There has been considerable controversy over the years as to what is desirable weight gain during pregnancy, and guidelines have varied considerably over time. For example, the authors of an American textbook in obstetrics in 1966 stated that “excessive weight gain in pregnancy is highly undesirable for several reasons; it is essential to curtail the increment in gain to 28 lb (12.5 kg) at most and preferably 15 lb (6.8 kg)” [1]. Later, however, this policy of severe weight restriction of 6.8 kg was challenged when it was recognized that it was associated with low infant birth weight and with health problems in the offspring [1].
