Abstract:Objective To observe the effects of human body composition analyzer guided nutritional therapy on disease control in patients with gestational diabetes mellitus. Methods A total of 124 cases of patients with gestational diabetes mellitus who were admitted in our hospital from September 2016 to October 2017 were selected as the research subjects. They were randomly divided into treatment group and control group (n?=?62). The control group was given general diet guidance and normal prenatal examination, and patients in the treatment group was given nutritional prescriptions for medical nutrition treatment based on human body composition analysis. Personal behavior tracking files, delivery methods, maternal outcomes and perinatal outcomes were recorded. Results Rate of natural delivery was increased while rate of cesarean section was decreased in the treatment group compared with those in the control group (P?0.05). Incidence of adverse outcomes including hypertension, diabetes, hydramnion, pregnancy infection, perinatal macrosomia, neonatal asphyxia, perinatal death and NICU stay were decreased in the treatment group compared with those in the control group (P?0.05). Conclusions Human body composition analyzer guided nutritional therapy facilitate disease control for the patients with gestational diabetes and improves the maternal and infant outcomes.
