  2. Child’s sex: dummy code as 1 = Male, 0 = Female; Family member’s relationship to the child: dummy code as 1 = Mothers, 0 = Others; Number of friends: 1 = none, 2 = one friend, 3 = 2–3 friends, 4 = over 4 friends; Attendance at nursery/school: dummy code as 1 = Yes, 0 = No; Family attendance ratio was calculated that number of days of child hospitalization divided by number of days of family attendance in the previous a month.
