Anthropometric Measurements and Laboratory Methods for Pregnancy: An Update Review to Evaluation of Body Composition

The aim of this review is to summarize and put into context the current evidence on anthropometric measurements and laboratory methods used in the evaluation of body composition in pregnancy, in the light of current studies.

Protecting women's health during pregnancy, childbirth and the postnatal period is important for maternal health. Pregnancy is a critical period during which the female body undergoes significant changes to support fetal growth and development. Maternal changes in body composition are associated with fatal development and maternal health during pregnancy. Anthropometry is a simple, reliable, and low-cost method that can be applied globally in primary care for evaluating maternal nutritional status. Maternal anthropometry is important in predicting various complications that may occur during pregnancy, such as intrauterine growth retardation and the risk of low birth weight. In this context, anthropometric measurements such as body weight, skinfold thickness, and middle upper arm circumference, and laboratory methods such as body water, body density, bioelectrical impedance analysis, ultrasound, dual-energy X-ray absorptiometry, and magnetic resonance imaging are frequently used in estimating the body composition of pregnant women. In addition to body weight gain monitoring, it is possible to determine the body composition of a pregnant woman by using different anthropometric measurements and the proposed equations. Accurate evaluation of anthropometric measurements and body composition in pregnant women is important in protecting the health of the mother and baby and in the early diagnosis of complications that may occur during pregnancy.
