Number of pill/day × Number of follow-up days

Results: One hundred and twenty five HIV infected children, 71 girls and 54 boys, included in the study. There was a total of 808 visits ; young age group of 395 visits and older age group of 413 visits. Young and older age group achieved good adherence by 73.1 % and 77.0 % respectively, p=0.21. Despite no difference in the percentage of good adherence between these 2 groups, the older age group became less adherent by the follow-up period, especially during and after 288-322 weeks and more than 322 weeks. Good adherences were 65.1% and 86.5% of medication given by self-giving in older children and parents, respectively. No other factors affected the adherence to drug therapy.
