Fig. 5

Child diversity and adult educational level at 4 survey times: baseline, 12, 24, and 48 months. Educational levels are indicated by the following categories: None = none or basic, Primary = some or completed primary school, Secondary = some or completed secondary school (or beyond). Child diet diversity improved markedly in households where adult educational levels were higher (p < .01 for men and women). Notably, child diet diversity did not increase at all in households where no adult had received any formal education (None-All). (For simplicity, mother’s educational level is not shown but was essentially collinear with women’s education). *p < .05, **p < .01, ***p < .001, ^p < .0001
