MPA, mean probability of adequacy.

Square-root transformed.

^†

Linear regression model with MPA as the dependent variable and the independent variables that remained significant at the P<0·20 level after initial testing. Variables which were tested but not found significant were infant’s age and sex, parity, women’s occupation and husband’s occupation.

^‡

Natural-log transformed.

^§

Usual energy intake according to the Multiple Source Method⁽ ²² ^, ²³ ⁾.

^||

Mean dietary diversity score.

^¶

Treated as continuous variable from 1 (no schooling) to 6 (higher education).
