Indoor tobacco smoke exposure of asthmatic children

It was suggested that indoor exposure of tobacco smoke could be associated with early asthma onset in childhood because of the high concentration of toxic compounds in side stream smoke. The aim of study was to research parental and maternal smoking in families with asthmatic child. During 1998.-2000. study included 188 asthmatic children divided in two groups: 87 (46%) passive smokers (PS) and 101 (54%) non-exposed subjects (NS). In PS group 37 (42.5%) fathers smoked only, 17 (19.5%) mothers and 33 (38%) both parents. Finely in 188 families 70 (37%) fathers, 50 (27%) mothers and 31 (16%) mothers during pregnancy were smokers. During 1996. in our country 50.2% fathers and 35.2% mothers of children up to 5 yrs were smokers (J. Grgurić, Z. Zahunj. Parental smoking and its effects on children. Pediatr Croat 1999 ; 43:57-63). Children were aged in PS group 9.9±3.5 yrs, in NS 9.2±3.3 yrs. The first attack of airway obstruction was in PS at 4±3.6 yrs, in NS at 3.44±3.5 yrs, with annual frequency of 6.9±7.7 (PS) and 7±5.7 (NS). Famly history of allergic disorders had in PS group 71 (82%), in NS 76 (75%). Positive skin-prick test to common inhaled allergens had in PS 81%, in NS 82%, to house dust mite 64% in both groups, to pollens 39% (PS), 49% (NS) and to tobacco 24% (PS) and 22% (NS). Conclusion: Although parental smoking can influence on early asthma onset we couldn’t find any significant difference in the first symptoms, frequency of attacks or in allergic parameters (skin test to inhaled allergens, level of serum IgE antibodies) between tobacco exposed and non-exposed asthmatic children.
