**Assisted Delivery:** - No reliable indicators were found to predict a lower probability of assisted delivery. - Maternal height, despite its known risks, did not emerge as a strong indicator due to the inclusion of critically low stature women, diluting the risk. - Analysis using deciles showed more predictive power for maternal height. **Pre-eclampsia:** - No generally accepted definition exists for hypertensive disorders of pregnancy. - Prevalence ranged from below 1% to 15%. - None of the indicators strongly predicted pre-eclampsia, with the highest odds ratios just above 1. - Poor maternal nutritional status was associated with a reduced risk, but scientific evidence is weak. - Maternal height, pre-pregnancy weight, and arm circumference showed neutral or marginally negative relationships. - BMI at different stages of pregnancy had small estimated mean ORs ranging from 0.6 to 0.9. **Sensitivity and Specificity:** - Only BMI/9 had a minimum study sensitivity of 0.05. - Several indicators showed study sensitivities dropping below 0.1. - Pre-pregnancy BMI was the only indicator meeting the Se/Sp criteria in over 40% of studies. - Overall, maternal anthropometry was a poor predictor of pre-eclampsia due to confounding effects of late pregnancy edema. **Postpartum Haemorrhage:** - No known biological basis for a relationship between maternal nutritional status and postpartum hemorrhage. - Prevalence was very low (0.5–4.4%). - All estimated ORs were below 1, except for attained BMI indicators, which showed a marginal elevated risk. - Attained weight by month 9 and MUAC had ORs of 0.6, suggesting a reduced risk, but more data is needed to confirm this. Overall, maternal anthropometry and nutritional status did not strongly predict assisted delivery, pre-eclampsia, or postpartum hemorrhage, with most indicators showing neutral or marginally negative relationships.**Assisted Delivery:** - No reliable indicators were found to predict a lower probability of assisted delivery. - Maternal height, despite its known risks, did not emerge as a strong indicator due to the inclusion of critically low stature women, diluting the risk. - Analysis using deciles showed more predictive power for maternal height. **Pre-eclampsia:** - No generally accepted definition exists for hypertensive disorders of pregnancy. - Prevalence ranged from below 1% to 15%. - None of the indicators strongly predicted pre-eclampsia, with the highest odds ratios just above 1. - Poor maternal nutritional status was associated with a reduced risk, but scientific evidence is weak. - Maternal height, pre-pregnancy weight, and arm circumference showed neutral or marginally negative relationships. - BMI at different stages of pregnancy had small estimated mean ORs ranging from 0.6 to 0.9. **Sensitivity and Specificity:** - Only BMI/9 had a minimum study sensitivity of 0.05. - Several indicators showed study sensitivities dropping below 0.1. - Pre-pregnancy BMI was the only indicator meeting the Se/Sp criteria in over 40% of studies. - Overall, maternal anthropometry was a poor predictor of pre-eclampsia due to confounding effects of late pregnancy edema. **Postpartum Haemorrhage:** - No known biological basis for a relationship between maternal nutritional status and postpartum hemorrhage. - Prevalence was very low (0.5–4.4%). - All estimated ORs were below 1, except for attained BMI indicators, which showed a marginal elevated risk. - Attained weight by month 9 and MUAC had ORs of 0.6, suggesting a reduced risk, but more data is needed to confirm this.
