ADHD

A new study suggests that secondhand smoke increases the risk of disorders mental and behavioral in children, including ADHD.

Summary

Exposure to secondhand smoke is associated with cardiac and respiratory problems in children. In addition, research suggests, breathing secondhand smoke increase the risk of developing mental and behavioral disorders in children, including attention deficit disorder with hyperactivity (ADHD).

team Frank Bandiera, Miller School of Medicine, University of Miami, studied the relationship between secondhand smoke and mental health in a representative sample of the country with nearly 3,000 children between 8 and 15.
study midió el nivel de nicotina en sangre para detectar qué niños habían estado expuestos al humo de segunda mano. A aquellos con los niveles más altos se los consideró fumadores y se los excluyó. Además, el equipo entrevistó a todos los participantes para identificar síntomas mentales o conductuales.

Tras considerar factores como la edad y la etnia, los varones expuestos al humo de segunda mano eran más propensos a tener síntomas de TDAH, depresión, ansiedad y trastornos de conducta que los que no estaban expuestos al humo de cigarrillo. Las niñas expuestas al humo de segunda mano tenían sólo más síntomas de TDAH y de ansiedad que el resto.

Aun así, la cantidad children with most of these diseases diagnosed remained low. While 201 children (7 percent) had sufficient symptoms to be diagnosed as ADHD, only 15 were diagnosed with depression and anxiety disorder to nine participants.

The authors acknowledge that it is difficult to separate the effects of second-hand smoke damage they could cause mothers to smoke during pregnancy. Further studies are needed to determine how exposure to secondhand smoke can affect children's brains.

The authors conclude that it needs to extend the ban on smoking in public places where children and avoid childhood exposure to secondhand smoke at home.
