Analysis reveals impact of poverty and family adversity on adolescent health

In the UK today, persistent poverty and/or persistent poor parental mental health affects over four in ten children, University of Liverpool researchers have found.

The combination of both affects one in ten children and is strongly associated with adverse child outcomes, particularly poor child mental health, reveals their study published today in the Lancet Regional Health Europe.

Corresponding author Dr Nicholas Kofi Adjei said: “This study is the first to assess the clustering of trajectories of child poverty and multiple indicators of family adversities - including parental mental ill health, domestic violence and abuse, alcohol misuse and their impacts on subsequent child behaviour and health outcomes in adolescence - in a representative UK sample.”

The researchers, from the University of Liverpool, Newcastle University, King’s College London and Stockholm University used longitudinal data from the UK Millennium Cohort study on 11564 children followed to age 14 years. Family adversities included parent-reported domestic violence and abuse, poor mental health and frequent alcohol use. Six trajectories of poverty and family adversity for children were identified: Low poverty and family adversity (43.2% of those included in analysis), persistent parental alcohol use (7.7%), persistent domestic violence and abuse (3.4%), persistent poor parental mental health (11.1%), persistent poverty (22.6%) and persistent poverty and poor parental mental health (11.1%).

Compared with children exposed to low poverty and adversity, children in the persistent adversity trajectory groups experienced worse outcomes with those exposed to persistent poor parental mental health and poverty were particularly at increased risk of socioemotional behavioural problems, cognitive disability, drug experimentation and obesity.

Dr Adjei said: “Our longitudinal analysis provides strong evidence that adverse conditions have important effects on children’s lives, but it is even more detrimental when multiple risk factors co-occur. The findings add to the current body of evidence by showing that poor parental mental health and poverty co-occur or cluster and their persistence across the developmental stages is associated with adverse child outcomes, particularly poor child mental health.

“The study demonstrates that interventions to address specific childhood adversities may not be meaningful if childhood socioeconomic conditions are not considered.”

The researchers have outlined several recommendations following the analysis, says Professor David Taylor-Robinson, the senior author on the study: “The cluster of poverty and poor parental mental health is common, and particularly harmful to children’s health. In the UK, immediate policy considerations include increasing child benefits and the child support element in universal credit uplift reversing changes to the welfare system that have led to rising child poverty, re-investing in support services and children’s preventive services such as children’s centres, and improving access to mental health services for families.”

This study is part of the Overcoming Adverse Childhood Experiences (ORACLE) project funded by the National Institute of Health Research (NIHR). The main aim of the project is to understand the lived experiences of children, young people, and family members, and wider structural determinants, of risks and assets around parental mental health problems, substance misuse and intimate partner abuse. ORACLE is led by Professor Ingrid Wolfe (King’s College London), Professor Eileen Kaner (Newcastle University) and Professor David Taylor-Robinson (University of Liverpool).

This study was funded by The National Institute for Health Research (NIHR) Policy Research Programme, NIHR Applied Research Collaboration South London (ARC South London) at King’s College Hospital NHS Foundation Trust and the Medical Research Council (MRC).

The mission of the National Institute for Health Research (NIHR) is to improve the health and wealth of the nation through research. We do this by:

•              Funding high quality, timely research that benefits the NHS, public health and social care;

•              Investing in world-class expertise, facilities and a skilled delivery workforce to translate discoveries into improved treatments and services;

•              Partnering with patients, service users, carers and communities, improving the relevance, quality and impact of our research;

•              Attracting, training and supporting the best researchers to tackle complex health and social care challenges;

•              Collaborating with other public funders, charities and industry to help shape a cohesive and globally competitive research system;

•              Funding applied global health research and training to meet the needs of the poorest people in low and middle income countries.

NIHR is funded by the Department of Health and Social Care. Its work in low and middle income countries is principally funded through UK Aid from the UK government.
