Badley EM, et al. - Researchers intended to determine if there is an association between the frequency and severity of different types of childhood maltreatment and adulthood arthritis. Analysis of the 2012 Canadian Community Health Survey–Mental Health involved 21,889 participants ages ≥ 18 years. By asking about “things that may have happened to you before you were 16 in your school, in your neighborhood, or in your family,” severity and frequency of childhood physical abuse (CPA), and childhood sexual abuse, and the frequency of childhood exposure to intimate partner violence (CEIPV) were assessed. In total, 17.5% of respondents reported arthritis. The authors discovered that the higher the frequency and severity of childhood maltreatment, the higher the magnitude of relationship with arthritis. This may indicate the role of the enduring immune and metabolic abnormalities and chronic inflammation related to childhood maltreatment in osteoarthritis (OA) etiopathogensis or may be an indication of the role of joint injury in causing OA. Arthritis remained independently linked to severe and/or frequent CPA (dose-response relationship) and frequent CEIPV after controlling for all covariates.
