Background and aims: Evidence is extensively available to predict maternal outcomes from nutritional status and intake during late pregnancy but inconclusive to specifically conclude which anthropometric and dietary variables are linked to low birth length (LBL). This study explored which anthropometric measurements and dietary intakes during late pregnancy were correlated with LBL
Methods: This cohort followed a total of 139 pregnant women throughout their last trimester. Mothers’ mid-upper arm circumference (MUAC) and height were recorded once at the start of the study using a measuring tape and stature meter, respectively. Maternal weight and energy and macronutrient intakes were recorded in early, mid, and late 3rd trimester using a digital weight scale and semi-quantitative food frequency questionnaire (SQFFQ), respectively. Birth length data was collected from verified birth reports. Statistical analyses were done employing Spearman’s Rank Correlation, Chi-Square, and ANOVA tests.
Results: ANOVA test demonstrated that during the 3rd trimester, maternal weight increased significantly each month (p<0.05). Total energy but no single macronutrient intakes were significantly different between months and the highest in early 3rd trimester (2483±76 kcal, p<0.05). Spearman’s Rank Test indicated that mother’s height (R=0.31), MUAC (R=0.23), maternal weights in early (R=0.34), mid (R=0.31), and late (R=0.37) 3rd trimester were positively correlated with birth length (p<0.05). However Chi-Square test only endorsed the association of low maternal MUAC and LBL (OR=4.11, 95%CI=1.37-12.34). 
Conclusions: LBL may be predicted from low mother’s MUAC. Additionally, increased mother’s height and maternal weight during the last trimester were correlated with increased birth length.
