Does cumulative adverse socioeconomic exposure mediate the association of maternal mental ill health at birth and adolescent mental ill health at age 17? An analysis of the Millennium Cohort Study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAdolescent mental health is a public health priority. Maternal mental ill health and adverse socioeconomic exposure (ASE) are known risk factors of adolescent mental ill health. However, little is known about the extent to which cumulative ASE over the life course mediates the maternal-adolescent mental health association, which this study aims to explore.
methodsWe analysed data from more than 5000 children across seven waves of the UK Millennium Cohort Study. Adolescent mental ill health was measured using the Kessler 6 (K6) and Strengths and Difficulties Questionnaire (SDQ) at age 17. The exposure was maternal mental ill health as measured by the Malaise Inventory at the child's birth. Mediators were three measures of cumulative ASE defined by maternal employment, housing tenure and household poverty. Confounders measured at 9 months were also adjusted for, these were: maternal age, maternal ethnicity, household poverty, maternal employment, housing tenure, maternal complications during labour and maternal education. Using causal mediation analysis, we assessed the cumulative impact of ASE on the maternal-adolescent mental ill health relationship between birth and age 17.
resultsThe study found a crude association between mothers' mental health at the child's birth and mental health of their children at age 17, however, when adjusting for confounders this association was reduced and no longer significant. We did not find an association between cumulative exposure to maternal non-employment or unstable housing over the child's life course and adolescent mental health, however, cumulative poverty was associated with adolescent mental ill health (K6: 1.15 (1.04, 1.26), SDQ: 1.16 (1.05, 1.27)). Including the cumulative ASE measures as mediators reduced the association between maternal and adolescent mental health, but only by a small amount.
conclusionsWe find little evidence of a mediation effect from cumulative ASE measures. Experiencing cumulative poverty between the ages of 3-14 was associated with an increased risk of adolescent mental ill health at age 17, suggesting actions alleviating poverty during childhood may reduce adolescent mental health problems.
