Scientists from Sweden claim that younger children in the family are less susceptible to colds or asthma than older.

Scientists in the published work say that the analyzed medical histories of three hundred thousand children of different age groups carry a pattern. Catarrhal diseases, as well as diseases associated with the respiratory system, are most often affected by older children of the family.

Scientists have analyzed the spread of childhood diseases at the age of 6-12 years.

In addition to older children, those children who were the only ones in the family - often turned out to be asthmatic patients, were at risk for frequent diseases..

Scientists think that the main reason for this phenomenon is the frequent treatment of mothers to a greater extent with the first-born at an early age.. In addition to this phenomenon, diabetes, hyperactivity disorder and insufficient attention syndrome were also common diseases of older children..
