Children and adolescents living in relative poverty – regardless of overall material conditions – tend to experience more interpersonal violence, family turmoil, and environmental hazards that increase risk of injury, engage in more health compromising behaviours (e.g., physical inactivity, poor nutrition, smoking), report lower subjective well-being, and exhibit more social skills deficits and emotional and behavioural problems.

International studies of inequalities in adolescent health tend to focus on the socio-economic gradient in average outcomes rather than their dispersion within countries. Although understanding the extent to which differences in health are related to socio-economic disadvantage is important, focusing exclusively on socio-economic status risks neglecting differences in the distribution of health outcomes within and between countries. To fill this research gap, this study analyses variation in the extent of inequality in the lower half of the distribution in five indicators of adolescent health and well-being – health symptoms, physical activity, healthy eating, unhealthy eating, and life satisfaction – across EU and/or OECD countries that took part in the latest cycle of the Health Behaviour in School-aged Children study.

A large body of literature has established socio-economic gradients in adolescent health, but few studies have investigated the extent to which these gradients are associated with very poor health outcomes. The current analysis examined the extent to which the socio-economic background of adolescents relates to very poor self-reported health and well-being (the so-called ’bottom end’). We examined the following as indicators of adolescent health: psychosomatic health complaints; physical activity; healthy eating; unhealthy eating; and life satisfaction. Adolescents who scored below the mean of the lower half of the distribution of a given indicator fall in the “bottom group” on this indicator. The largest, most persistent and widespread socio-economic gradients are in life satisfaction, physical activity and healthy eating, while the findings are mixed for unhealthy eating and psychosomatic health. Socio-economic inequalities were largely stable, but in a sizeable minority of the countries, socio-economic inequalities in physical activity and healthy eating have widened between 2001/02 and 2013/14, while inequalities in unhealthy eating and life satisfaction have narrowed in several countries.

Existing evidence is inconclusive on whether a socio-economic gradient in children’s cognitive ability widens, narrows or remains stable over time and there is little research on the extent of ‘cognitive mobility’ of children who had a poor start in life compared to their peers. Using data from five sweeps of the United Kingdom (UK) Millennium Cohort Study (MCS) at the ages of 9 months, 3 years, 5 years, 7 years and 11 years, this paper explores the cognitive ability trajectory of children in the bottom decile of the distribution at a given age, and the factors that drive or hinder their progress relative to their peers. The paper analyses children’s risks of moving in and out of the bottom decile of the cognitive ability distribution. The findings indicate a relatively high level of cognitive mobility between ages 3 and 11, especially in the pre-school period (between ages 3 and 5), with children from income-poor households more likely to get ‘trapped’ in the bottom of the age-specific cognitive ability distribution.

The extent to which the socio-demographic composition of child populations drives inequality in child well-being depends on which children are most likely to do much worse than their peers. In this Research Brief we present evidence on the socio-economic vulnerability of immigrant children and highlight the relative contribution of immigrant background to the risks of falling behind in household income, education, health and life satisfaction.
