A 3 year-study of emergency room visits (total 50,300) to the paediatric clinic of the main teaching hospital in Kuwait revealed that the rates of bronchial asthmatic attacks increased significantly from 8.8% of all visits during the 1st year to 14.9% during the 3rd year. The seasonal distribution of asthmatic attacks showed maximum rates during the winter and minimum values in the summer, giving a very close inverse correlation to temperature and direct correlation to relative humidity. A similar, excellent correlation was seen between asthmatic attacks and upper respiratory infections. Occurrence of atmospheric pollen, which characteristically shows a bi-annual pattern i Kuwait, was not found to correlate with asthma attack rates. Neither was there any demonstrable effect of dust storms on the frequency of asthmatic attacks in the children. Independent of season, the boy to girl ratio among the asthma cases was remarkably constant, around 2:1.

“…We have earlier shown that cross-gender transmission from mother to son might at least partly explain this increased risk among the male infants. 30 However, other studies have pointed at a relative smaller size, 31,32 increased airway tone, 33 and/or a greater lability 34,35 of the airways in boys, thus increasing their risk of dyspnea when infected. The increased risk associated with the presence of siblings was also present only in infancy and was strongest among the youngest infants.…”

“…The male predominance may be related to a greater degree of bronchial lability in males. 22 More recently, a female preponderance was found, which was attributed to the fact that living in ill-ventilated houses, use of cow-dung cakes and agriculture waste as fuel for cooking and girls always helping the mothers to cook in the kitchen lead to airway inflammation and asthma. 15 The inverse linear relationship between bronchial asthma and age that we report is a known phenomenon.…”
