A U-shaped association between the pBMI and IDA was observed, with decreased odds (OR; 95 % CI) for OW subjects (0\u00b76; 95 % CI (0\u00b74, 0\u00b79)) but increased odds for UW (1\u00b72; 95 % CI (0\u00b78, 2\u00b70)) and OB subjects (1\u00b72; 95 % CI (0\u00b78, 1\u00b78)).

Compared to normal weight, OB pregnant women had 3\u00b74-fold (3\u00b74; 95 % CI (1\u00b74, 8\u00b71)) higher odds for multiple mild nutritional deficiencies, while UW individuals had lowest odds (0\u00b73; 95 % CI (0\u00b71, 1\u00b72)).
