Antibiotic use in kids down, but resistance feared in preschoolers: study
Antibiotic use among children is decreasing overall, but prescriptions of one class of the bacteria-killers have risen dramatically for children under five, raising fears that drug-resistant strains could soon develop among Canadian preschoolers, research suggests.

And in one of two studies published Tuesday in the Canadian Medical Association Journal, the researchers found that the decision to prescribe an antibiotic often depends not only on whether a doctor is a general practitioner or specialist, but also on the income level of parents and whether a child is male or female.
