Moving house 'damages child health'

Have your say

“Parents who frequently move house put children’s health at risk,” according to the Daily Mail. The newspaper said that research found moving several times can affect children’s health and psychological state, and also increases the likelihood that a child may use illegal drugs.

This Scottish research, which looked at potential links between moving house in childhood and adult health, produced far more mixed results than the Mail implied. However, the press release accompanying the research did not always clearly reflect the findings of the study, which found very few significant links between moving frequently and poor health.

In fact, once the researchers accounted for factors such as social deprivation and moving schools, moving house was only significantly linked to a higher chance of using drugs in later life. Adults who had moved frequently showed no greater risk of being overweight, having high blood pressure, long-term illness, psychological distress, drinking or smoking later in life.

While researchers say the risk of having certain measures of poor health was “elevated” in people who moved house more frequently as a child, the increase in risk was not statistically significant, which means it could have happened by chance.


The study was carried out by researchers from the Medical Research Council, the University of Stirling, Queen’s University and Scotland’s Chief Scientist Office. It was funded by the Chief Scientist Office of the Scottish Government Health Directorate. The study was published in the peer-reviewed Journal of Epidemiology and Community Health.

The study’s findings were overstated by the Daily Mail. The newspaper reported that there were “negative health effects” from frequent moves, whereas the study found that frequent moving was only significantly linked to an increased chance of drug use. This finding on drug use was independent of other variables.

Moving during childhood was not significantly associated with adult measures of physical health, such as weight and blood pressure. The Mail only touched on these elements towards the end of its report.

It’s worth noting that in the press release that accompanied publication of the study, only the penultimate paragraph stated that only illegal drug use was independently associated with frequent moves.


This research was part of a large cohort study from the west of Scotland, which has taken place over 20 years. It compared the health of people who had been “residentially stable” during childhood with those who had moved house, using a range of health measures.

The authors say previous research suggests that frequent childhood moves may be associated with poorer health outcomes and behaviour in adolescence. The researchers say their present study brings together a wider range of health outcomes than has previously been considered, and also looked at the extent to which associations between childhood mobility and health in adolescence last into adulthood.


The study was based on a cohort of 1,515 participants who were 15 when it started in 1987 and who were followed up for 20 years. Data from this cohort were collected at five points in time, the final time when the participants were 36. The final sample analysed in the study was 850 participants, so 665 original participants (44%) were not included in the final analysis because they had left the study.

Researchers collected their data through face-to-face interviews conducted by nurses. A parental questionnaire was completed at the start of the study.

The researchers got information about moving house from the number of addresses people had lived at between birth and 18 (they excluded recent moves out of the family home).  They collected information on a range of health measures including:

Importantly, the researchers also looked at participants’ family and household circumstances based on information provided by the children’s parents at the start. They also looked at other factors such as social deprivation (calculated by postcode and using recognised deprivation categories), housing status (home-owner or not), social class, family structure (intact or not) and number of siblings. Also included were data on school mobility, derived from the number of primary and secondary schools attended. The researchers also looked at participants’ social class, education and marital status in adulthood.

The researchers then analysed the relationship between number of house moves in childhood and health at the ages of 18 and 36. They adjusted their findings for possible confounders, such as social class, deprivation and family circumstances.


The researchers found that approximately one in five people did not move address throughout childhood. Three in ten moved once or twice, and a further one in five had moved at least three times. They also found that children in single-parent households and those with two or three siblings were significantly more likely to have moved home (while those with at least four siblings were more likely to have stayed put).

After they adjusted their findings for both socioeconomic circumstances and the number of school moves, the researchers found that, when the participants were 18:

When the participants were aged 36, the researchers found that:


The researchers concluded that increased residential mobility in childhood is associated with an elevated risk of poor health in adulthood, across a range of measures. This is explained in part, they say, by both social and economic circumstances and the frequency of school moves.

The relationship between childhood residential mobility and poorer health appeared to be stronger in adolescence than adulthood, possibly because people’s own socioeconomic circumstances lessened the effects over time.


This study looked at the effect of multiple address moves during childhood on people’s physical and psychological health at the ages of 18 and 36.

The way the authors interpreted the results of their study is confusing. They say that a higher risk of poor health outcomes is associated with frequent moves of home in childhood. However, the only significantly higher risk, once the results were adjusted for various confounders, was illegal drug use. This is important because it means that the other increases in risk identified are more likely to have occurred by chance.

The study examined an important issue, and one strength is the length of time of it covered. Another is its detailed collection of data, which might help explain why frequent moves of house could have an association with poorer health outcomes. For example, this could be because of frequent school moves, family break-up and deprivation.

However, the study has a number of limitations. Its high drop-out rate (around 43%) raises the question of reliability and it is possible that those who dropped out or were lost to follow-up also had the most mobile childhoods. The study’s reliance on the parents to report outcomes, such as overall health, is another limitation as their reports may be subjective or difficult to appraise.

Families move home for a range of different reasons, including improved schooling and employment opportunities, change in financial circumstances or family break-up, and the study did not assess the reasons for the family moves. It seems obvious that children are more likely to be negatively affected when disruption or financial problems cause a family to move, rather than when the motive is to seek better schools or a better job.

The way children’s wellbeing is affected by frequent moving is an important issue, but it is also a complex one which needs to be examined further.
