Parameters estimates were adjusted for the tabulated variables. Ref: indicates the reference category.

Maximum Variance inflation factor  =  1.96.

Parameters estimates adjusted for: Dependency ratio, household income, gender of the household head.

Coefficients as obtained from a multivariable linear regression model.

High =  3rd tertile for both DDS and frequency of ASF consumption.

Adol =  Adolescent.
