ObjectiveWe assessed whether maternal mental health problems increased rates for child injury during the preschool years and mid-childhood, and the extent to which associations could be accounted for by a range of potential explanatory factors.DesignWe analysed the UK Millennium Cohort Study, a nationally representative sample with data collected throughout childhood. Multinomial regression was used to investigate whether two measures of maternal mental health (diagnosed depression/anxiety and psychological distress) were associated with subsequent childhood injury. Models adjusted for sociodemographics, parenting and child externalising behaviours.Main outcome measureMaternal report of unintentional injuries (none, 1, 2+) recorded at three data collection periods (3–5 years; 5–7 years; 7–11 years).ResultsThe analytic sample comprised n=9240 families who participated 3–11 years with complete data on exposures and outcomes (multiply imputing missing covariates). Exposure to maternal mental health problems was associated with increased rates of subsequent childhood injuries. Associations attenuated after adjustment for potential explanatory factors, although they remained elevated. For example, high maternal distress was associated with injuries 3–5 years (adjusted relative risk ratio (aRRR): 1 injury=1.18, 95% CI 0.86 to 1.61; 2+ injuries=2.22, 95% CI 1.22 to 4.02); injuries 5–7 years (aRRR: 1 injury=1.31, 95% CI 0.97 to 1.76; 2+ injuries=1.84, 95% CI 1.09 to 3.09); and injuries 7–11 years (aRRR: 1 injury=1.03, 95% CI 0.81 to 1.31; 2+ injuries=1.33, 95% CI 0.97 to 1.81).ConclusionsChildren exposed to mothers with mental health problems had higher rates of childhood injury than those not exposed. If further investigation of this association suggests causality then it will be important to test measures that address mothers’ mental health issues with a view to reducing injuries among their children.

AbstractBackgroundPsychological distress is common among women of childbearing age, and limited longitudinal research suggests prolonged exposure to maternal distress is linked to child mental health problems. Estimating effects of maternal distress over time is difficult due to potential influences of child mental health problems on maternal distress and time-varying confounding by family circumstances.MethodsWe analysed the UK Millennium Cohort Study, a nationally representative sample with data collected throughout childhood. Adopting a marginal structural modelling framework, we investigated effects of exposure to medium/high levels of maternal psychological distress (Kessler-6 score 8+) on child mental health problems (Strengths and Difficulties Questionnaire borderline/abnormal behaviour cut-off) using maternal and child mental health data at 3, 5, 7 and 11 years, accounting for the influence of child mental health on subsequent maternal distress, and baseline and time-varying confounding.ResultsPrior and concurrent exposures to maternal distress were associated with higher levels of child mental health problems at ages 3, 5, 7 and 11 years. For example, elevated risks of child mental health problems at 11 years were associated with exposure to maternal distress from 3 years [risk ratio (RR) 1.27 (95% confidence interval (CI) 1.08–1.49)] to 11 years [RR 2.15 (95% CI 1.89–2.45)]. Prolonged exposure to maternal distress at ages 3, 5, 7 and 11 resulted in an almost fivefold increased risk of child mental health problems.ConclusionsPrior, concurrent and, particularly, prolonged exposure to maternal distress raises risks for child mental health problems. Greater support for mothers experiencing distress is likely to benefit the mental health of their children.
