Child maltreatment and living standards in adulthood: findings from a prospective birth cohort

Abstract

BackgroundChild maltreatment (abuse and neglect) has well-established effects on mental health, but less is known about its influence on adult life economic circumstances. We aimed to establish associations of child maltreatment with such outcomes in mid-life. MethodsWe used data from the 1958 British birth cohort (n=8076) on child neglect and abuse (physical, sexual, psychological, and witnessing abuse) and adult (at age 50 years) long-term sickness absence, not in employment, education, or training (NEET), lacking assets, income-related support, poor educational qualifications, financial insecurity, manual social class, and social mobility. Logistic regression was used to assess associations with maltreatment separately and combined as a score (0, 1, ≥2) with and without adjustment for potential confounding factors (maternal age, birthweight, birth order, social class at birth, parental education, household amenities, crowding, and tenure at age 7 years). Missing values were imputed with multiple imputation chained equations. FindingsAbuse prevalence varied from 1% (n=115) for sexual abuse to 10% (776) for psychological abuse; 1208 (16%) were defined as neglected. 1506 (19%) of the population experienced one type of maltreatment, and 585 (7%) experienced two or more. All maltreatments were associated with most outcomes (eg, for physical abuse, adjusted odds ratio [OR] of long-term sickness absence was 2·33, 95% CI 1·62–3·35). There was a trend across multiple types of maltreatment and unfavourable outcomes—eg, adjusted OR for NEET increased for one and two or more maltreatments compared with no maltreatment (1·30 [1·02–1·65] and 1·72 [1·28–2·33], respectively; ptrend<0·0001). Likewise, adjusted OR for three or more unfavourable adult outcomes increased with more maltreatment compared with none (1·94 [1·59–2·37] for one and 2·23 (1·75–2·84] for two or more; ptrend<0·0001). Children who were sexually abused or neglected were less likely than those not sexually abused or neglected, respectively, to be upwardly mobile from birth to mid-adulthood (unadjusted OR 0·49 [0·30–0·81] and 0·45 [0·39–0·53]). InterpretationChild abuse was reported retrospectively in adulthood, although child neglect and potential confounding factors were ascertained prospectively and we examined a wide range of adult socioeconomic outcomes that are important because of their costs to individuals and society. That childhood maltreatments were associated with most unfavourable outcomes in mid-adulthood, has implications for the broader field of health equity. The increasing risk of poor adult outcome associated with multiple types of maltreatment suggests that they have an accumulating burden.
