The researchers found that the British laws banning smoking significantly reduced the incidence of asthma in children in this country, according to an online edition for girls and women from 14 to 35 years old Pannochka. net Immediately after the introduction of strict anti-nicotine laws, the number of hospitalizations of children with asthma attacks decreased by 8.9% (a balanced odds ratio of 0.91, 95% CI from 0.89 to 0.93).

This is reported by Dr. Christopher Millett of the Imperial College of London.

These laws also reduced the number of hospitalizations associated with complications of asthma by 3.4% in the first year after their implementation (balanced OR 0.97, 95% CI 0.96 to 0.98). Such data the researchers quote in the online edition of "Pediatrics".

"This seemingly insignificant change is equivalent to 6,122 hospitalizations during the first 3 years after the entry into force of the new legislation," the researchers.

Scientists also added that the study found a reduction in the number of visits to emergency departments of patients with complications caused by asthma associated with the ban on smoking.

The authors of this work studied the change in infant morbidity over a long period of time, starting from July 1, 2007, when the country imposed a smoking restriction. The number of hospitalizations was counted from April 2002 to November 2010. The study included children and adolescents under 14 years of age. In total during this period, 217,381 hospitalization cases.

All children were divided into two age categories - preschool children (0-4 years) and children of school age (5-14 years). This division helped to better understand the age differences in sensitivity to tobacco smoke. The authors note that children of the younger group were exposed to smoke mainly at home, and school-age children in public places and at school.

Patients were also divided into groups according to their social and economic status, the region of residence and sex. Among hospitalized children there were slightly more than half of preschool children (50.1%). Boys were more likely to enter the hospital with asthma and its complications (63.4%). And, finally, the overwhelming majority of hospitalized children are residents of urban areas (86.5%). It is surprising that most of the sick children live in high-income areas.

Prior to the introduction of antinucotin legislation, the incidence of hospitalizations of children with asthma attacks grew by 2.2% annually (a balanced OSH of 1.02, 95% of CI from 1.02 to 1.03). In the period from 2007 to 2010, this figure fell by 8.9%, decreasing each year by about 3%. And these are thousands of children who managed to stay healthy.

"In general, the new laws in the first year caused a decrease in the number of hospitalizations due to asthma and all its complications by as much as 12.3%," the researchers noted..

Further analysis showed no significant difference in results between representatives of different socio-economic groups, regions, etc..

The authors stated that their results coincide with the results of other European countries in which it was possible to adopt radical antinicotin laws. In their opinion, such positive results help to achieve "a ban on smoking in all indoor public spaces and workplaces".
