Birth weight is an important determinant of infant's well being as low birth weight is known to increase the risk adult onset of diseases like type-2 diabetes and ischemic heart disease. Maternal weight gain is one of the most important independent predictors of infant birth weight. Institute of Medicine of the National Academics, USA has recommended that total weight gain of mothers should be according to their prepregnancy body mass index (BMI). Therefore, this study was conducted to observe the total weight gained by the pregnant women and the correlation between the weights gained by them with the birth weight of their infants. 98 women who delivered full term single baby at Patan hospital were included after taking their verbal consent. The details of the newborn and the history of the pregnant women were taken from the hospital records. The information about the family income, dietary habit, birth spacing and the type of work done by the pregnant women was obtained from the women themselves. The mean weight gain of the mothers was 9.48 (SD = 3.41) kilograms and the mean birth weight of the infants was found to be 2965.66 (SD = 364.37) grams. Multiple Liner Regression Models showed the effect of Gestational weight gain (GWG), Age and Parity on birth weight of the infant. Step-wise multiple regressions gave rise to models that showed effect of GWG and age on birth weight of the infants. This study concluded that gestational weight gain has positive linear relationship (correlation) with the birth weight of infants.
出生体重是婴儿健康的一个重要决定因素，因为众所周知，低出生体重会增加成年后患2型糖尿病和缺血性心脏病等疾病的风险。孕妇体重增加是婴儿出生体重最重要的独立预测因素之一。美国国家科学院医学研究所建议，母亲的总体重增加应根据其孕前体重指数（BMI）来确定。因此，本研究旨在观察孕妇的总体重增加情况以及她们增加的体重与婴儿出生体重之间的相关性。在获得98名在帕坦医院足月分娩单胎婴儿的妇女的口头同意后，将她们纳入研究。新生儿的详细信息和孕妇的病史来自医院记录。关于家庭收入、饮食习惯、生育间隔和孕妇所从事工作类型的信息是从这些妇女本人那里获得的。母亲的平均体重增加为9.48（标准差 = 3.41）千克，婴儿的平均出生体重为2965.66（标准差 = 364.37）克。多元线性回归模型显示了孕期体重增加（GWG）、年龄和胎次对婴儿出生体重的影响。逐步多元回归产生了显示GWG和年龄对婴儿出生体重有影响的模型。本研究得出结论，孕期体重增加与婴儿出生体重呈正线性关系（相关性）。
