Children who often move house are more likely to suffer poor health, research suggests. Moving several times before the age of 18 can affect the health, psychological distress and increase the chance that a child may use illegal drugs.
The study included information for 850 people, followed-up for a period of 20 years. Scientists found changing home several times could cause psychological distress in children.
By the age of 18, 59 percent had moved house once or twice while one in five had moved at least three times. Some 20 percent had stayed in the same house during their childhood.
Children of single parents or those with step-parents were more likely to move home, as were those with two or three brothers or sisters. Those with four or more brothers and sisters were more likely to stay in the same house.
Experts found that people who moved at least once had an increased risk of poor health, some of this could be because of changing schools. Those who had moved three times or more were three times as likely to have had suicidal thoughts as those who stayed in the same house.
Dr Denise Brown said, “For many people, moving house is a good experience as it may lead to improved family conditions. But for some family members, especially children, moving can be bad and may lead to poor health outcomes and behaviors in adulthood. The bad effect on health in adulthood appears to be somewhat accounted for by a high number of school moves.”
