Background: Maternal nutrition has been reported to play a critical role in both the development and outcome of pregnancy. But, a causal correlation between obstetric nutrition risk (ONR), pregravid and gravid nutritional status (NS) and pregnancy outcome has not been established. The purpose of this work was to analyze the possible association between ONR, pregravid and gravid NS and maternal morbidity (MM).

Methods: This case control study included 180 pregnant patients admitted for high risk pregnancy (HRP). Patients were allocated in two groups (n = 90 p/group) using the ONR criteria on hospital admission: no nutritional risk group (Group A, ONR score < 3) and nutritional risk group (Group B, ONR score > 3). Study variables included: ONR scores, pregravid and gravid NS and MM.

Results: Average ONR scores were 1.24 ± 0.04 and 3.58 ± 0.07, on admission and 2.63 ± 0.18 and 4.88 ± 0.08 at discharge, on Groups A and B, respectively (p <0.001). Patients were “overweight” and “underweight” in Groups A and B, respectively (p <0.05). Hospital morbidity was identified in 10 (11.11%) and 44 (48.88%) patients in the no nutritional risk and nutritional risk groups, respectively (p <0.05. RR = 2.23; 95% CI 0.36 - 0.81).

Conclusion: There was a positive association between pregravid NS, Obstetric Nutritional Risk and MM in HRP. Nutritionally at-risk patients were underweight, showed a significantly higher morbidity and had longer hospital stays.
