Regression coefficients are not presented because the parameters were measured on different scales. These values are presented in the Additional file 1: Table S3. The sign (+/−) indicates the direction of the relationship and the “*”indicated the statistical significance (* p-value ≤ 0.15, ** p-value ≤ 0.1, *** p-value ≤ 0.05; Ch = child; HH = household; M = mother; n = sample size
^aquadratic function with peak at approximately 30 years
^bmother’s BMI was log transformed to improve normality of distribution
^cmother’s Hb was transformed as (Hb^3)/1000 to improve normality of distribution
