Does dietitian involvement during pregnancy improve birth outcomes? A systematic review

Healthy pregnancies can be achieved through sufficient weight gain, balanced diets, appropriate vitamin and mineral supplementation, avoidance of alcohol and harmful substances, as well as food safety (Procter et al., 2014). While most prenatal care providers do not have substantial training in nutrition, we believe that registered dietitians being healthcare professionals, can assist pregnant patients in attaining optimal birth outcomes. In Canada and the US, registered dietitians are not required members of health care teams for prenatal care, but can be referred to for medical nutrition therapy to assist women with weight gain, hyperemesis, multiple gestations, poor dietary patterns, and chronic disease (Procter et al, 2014). Given their expertise in nutrition and the importance of nutrition during pregnancy, registered dietitians have the potential to positively influence birth outcomes. However, studies supporting their roles have not been comprehensively evaluated (Pari-Keener et al., 2020) and existing studies have been inconsistent. Some studies have supported that interventions provided by dietitians improve infant birth outcomes. Research by Vesco et al. suggests that intensive dietary intervention initiated by dietitians is associated with a decrease in prevalence of large-for-gestational age infants (9%) compared to groups receiving only one-time dietary advice (26%) (2014). Additionally, research by Crowther et al. shows a significantly low incidence of large-for-gestational age (13%) and macrosomia (10%) infants as a result of dietitian involvement compared to its control group (22% and 21%) (2005). However, other studies indicate no effect on infant or maternal outcomes (Koivusalo et al., 2016; Dodd, Deussen & Louise, 2019). So far, no systematic review has directly studied the effect of dietitian involvement on birth outcomes. Thus, this review will examine the extent to which dietitian involvement during pregnancy is associated with improved birth outcomes. References Crowther, C. A., Hiller, J. E., Moss, J.
