Description of intervention(s) / exposure
Mother-infant pairs were randomised into four groups according to an experimental two-factor design taking into account infant location and apparel. Group I infants were placed skin-to-skin on their mother’s chest in the delivery ward. Infants were later kept roomed-in in the maternity ward. Group II infants were dressed and placed in their mother's arms. Infants were later kept roomed-in in the maternity ward. Group III infants were kept in a cot in the delivery and maternity ward nurseries with no rooming-in. Group IV infants were kept in a cot in a delivery ward nursery and later roomed-in in the maternity ward. Each group comprised two subgroups with infants either swaddled or kept in clothes. The duration of stay in the delivery ward was 2 first hours after birth; the duration of stay in the maternity ward lasted till discharge at day 5 after birth.
