Design outcomes

Primary

Measure	Time frame
Iron status (haemoglobin/Hb and ferritin level), measured using cyanmethemoglobin method for Hb level and enzyme-linked immunosorbent assay (ELISA) for ferritin level, at baseline (preconception period) and after intervention (13-16 weeks of gestation)	—

Secondary

Measure	Time frame
1. Timing of the first ANC, measured by calculating the difference between the date of the first ANC visit and the mother's first day of last menstruation, expressed in terms of the mother's gestational age in ‘days’ 2. Timing of the first iron supplement consumption, measured by calculating the difference between the date of the first iron supplement consumption and the mother's first day of last menstruation, expressed in terms of the mother's gestational age in ‘days’ 3. The number of iron supplement consumed during their first trimester of pregnancy, measured by asking the respondents at 13-16 weeks of gestation 4. Knowledge of preconception health and nutrition, measured using a 25-item self-administered validated questionnaire at baseline (preconception) and after the intervention (13-16 weeks of gestation) 5. Dietary intake measured using a semi-quantitative food frequency questionnaire at baseline (preconception) and after the intervention (13-16 weeks of gestation) 6. Weight measured using an electronic body scale with an accuracy of 0.1 kg at baseline (preconception) and after intervention (13-16 weeks of gestation) 7. Mid-upper arm circumference measured using a plastic measuring tape by looping the tape at the mid-point between the tip of the shoulder and the tip of the elbow of the left upper arm, at baseline (preconception) and after intervention (13-16 weeks of gestation)	—
