Comparison between body mass index and mid upper arm circumference for classifying nutritional status of pregnant women: a prospective cohort study

Background: BMI is used to assess nutritional status of pregnant women however weight gain during pregnancy confounds the later in pregnancy. Unlike weight, MUAC does not undergo significant change as advances. We aim compare changes and over various trimesters whether less compared weight.Methods: In this prospective observations study, measurements were taken 300 different trimesters. Chi-square tests conducted associations between socio-demographic indicators status. Correlation coefficients calculated three ANOVA on their respective mean differences trimesters.Results: Mean difference 0.43 cm (3.2%) was noted 5.32 kg/m2 (23.14%) from first third trimester. No observed MUACs second (p=0.326) (p=0.143) but, it significantly (p=0.003). Significant BMIs (p=0.05), (p<0.001) (p<0.001). positive all trimesters.Conclusions: Positive correlations found MUAC. Less than seems be a reliable tool for assessing antenatal women.
