Arthritis in adulthood linked to parental addictions during childhood
Published: March 26, 2014
The adult offspring of parents who were addicted to drugs or alcohol are more likely to have arthritis, says a new study by ߲ݴý researchers.
Investigators examined a group of 13,036 adults and found that 20.4 per cent of respondents had been diagnosed with arthritis by a medical professional. Investigators found that 14.5 per cent of all respondents reported having at least one parent whose drug or alcohol use caused problems while they were under the age of 18 and still living at home.
Results indicate that people whose parents were addicted to drugs or alcohol are more likely to have arthritis. After adjusting for age, sex, and race, parental addictions were associated with 58 per cent higher odds of arthritis, said lead author Esme Fuller-Thomson, professor and Sandra Rotman Endowed Chair in the University's Factor-Inwentash Faculty of Social Work and the Department of Family and Community Medicine.
"We had anticipated that the adult offspring’s health behaviors such as smoking, obesity and alcohol consumption might explain the strong link between parental addictions and arthritis, however we did not find this to be the case," said study co-author and recent Master of Social Work graduate, Jessica Liddycoat. "Even after adjusting for these adult health behaviors, as well as income, education, a history of childhood maltreatment and mood and anxiety disorders, we found that parental addictions was still a statistically significant factor associated with 30 per cent higher odds of arthritis."
Future prospective studies are needed because the survey nature of the data makes it impossible to determine whether the relationship between parental addictions and arthritis is causal.
“However, there is ample evidence from other studies to support the provision of efficacious interventions to treat addictions,” said coauthor Maria Stefanyk. “Although we do not know if these interventions will impact the development of arthritis in adulthood, we do know that children do much better on a wide range of outcomes when parents are no longer abusing drugs and alcohol.”
