Obesity may affect response to asthma medications
A new study led by the University of Michigan suggests that people who are overweight or obese may have better results with the prescription pill sold as Singulair than with a type of inhaled steroid, while leaner people may have better luck with an inhaled steroid, called beclomethasone and sold as beclovent, vanceril and other brand names.

Children's self-esteem can affect their response to asthma
While many urban children suffer from asthma, those who have high self-esteem and good problem-solving skills may be less likely to have their asthma symptoms interfere with school, a new study finds.
