Asthma children

Urban dwelling is a major risk factor for increased asthma morbidity, defined as higher rates of asthma-related emergency room visits and hospitalisation, says a study.

Australian researchers have found that children with vitamin D deficiency were more likely to develop asthma and other allergies later in life.

Over 300 million people worldwide suffer from asthma that affects people of all ages and groups, with one-tenth of those living in India.
