The relationship of food insecurity and the invitation time to start a prenatal food supplementation program(usual invitation: ~20 wk of gestation; early invitation: ~9 wk of gestation) on maternal-infant interaction (NCAST) scores among Bangladeshi mothers and infants (3.4–4.0 mo of age) in the MINIMat study¹

	Food insecurity scores

¹Values are means ± SD. Those with higher food insecurity scores had indications of severe food insecurity (scores above 17, 34% of the dyads). Those with lower food insecurity scores had indications of food security or occasional- to- moderate food insecurity (scores below or equal to 17, 66% of the dyads).

²-interaction of food insecurity score (continuous) and invitation time to start a prenatal food supplementation program as determined by general linear model equivalent to the model in Table 2.

³Total NCAST scores are the combination of total mother and total infant subscales.
