To asthma

Irish Independent - Health & Living - - UPDATE -

YOUNG Ir­ish chil­dren who de­velop res­pi­ra­tory tract in­fec­tions may have an in­creased risk of de­vel­op­ing asthma as they get older.

Some 155,000 chil­dren from a num­ber of Euro­pean coun­tries, in­clud­ing Ire­land, who were born be­tween 1989 and 2013 were stud­ied. They may also have poorer over­all lung func­tion later in life. Their his­tory of res­pi­ra­tory tract in­fec­tions was an­a­lysed be­tween the ages of six months and five years.

The chil­dren were then fol­lowed up un­til they were be­tween the ages of four years and 15 years, ac­cord­ing to re­searchers at Eras­mus MC Univer­sity Med­i­cal Cen­tre in the Nether­lands.

By the age of five years chil­dren who suf­fered with up­per res­pi­ra­tory in­fec­tions, such as colds, laryn­gi­tis, si­nusi­tis and ton­sil­li­tis, had a 1.5fold in­creased risk of de­vel­op­ing asthma as they got older.

They found chil­dren who had suf­fered from lower res­pi­ra­tory tract in­fec­tions, such as gen­eral chest in­fec­tions, bron­chi­tis and pneu­mo­nia, had a two-to-four-fold in­creased risk of de­vel­op­ing asthma when older.

The re­searchers said: “Fur­ther stud­ies that mea­sure lung func­tion and wheez­ing from birth on­wards are needed to explore whether the in­fec­tions cause asthma and lower lung func­tion, or whether wheez­ing and lower lung func­tion may be pre­dis­pos­ing these chil­dren to de­velop the in­fec­tions.”
