ABSTRACT
Objective: We aimed to investigate the relationship between Onodera's prognostic nutrition index (OPNI) and controlling nutritional status index (CONUT) that are used for evaluating the nutritional status and late-onset fetal growth restriction (FGR). Material and Methods: This study was a prospective cross-sectional study on 141 patients, which was conducted at the Medical Faculty of Selcuk University. The study included 62 women with late-onset FGR and 79 control patients. The control group was randomly selected from among pregnant women in the 32nd-37th gestational weeks with pre-pregnancy body mass index (BMI) 0.05). Before birth and pre-pregnancy weight, height, and pre-pregnancy BMI were significantly different between the groups (p0.05). We classified the CONUT score calculation according to two different cut-off values, and both classifications were similar between the groups (p>0.05). Conclusion: It has been shown that the OPNI and CONUT scores, which are used to predict nutritional status and prognosis in cancer and chronic diseases, are not useful to predict the late-onset FGR.
