Trends in psychological distress in Great Britain, 1991-2019: evidence from three representative surveys.

BACKGROUND: Previously improving UK mortality trends stalled around 2012, with evidence implicating economic policy as the cause. This paper examines whether trends in psychological distress across three population surveys show similar trends. METHODS: We report the percentages reporting psychological distress (4+ in the 12-item General Health Questionnaire) from Understanding Society (Great Britain, 1991-2019), Scottish Health Survey (SHeS, 1995-2019) and Health Survey for England (HSE, 2003-2018) for the population overall, and stratified by sex, age and area deprivation. Summary inequality indices were calculated and segmented regressions fitted to identify breakpoints after 2010. RESULTS: Psychological distress was higher in Understanding Society than in SHeS or HSE. There was slight improvement between 1992 and 2015 in Understanding Society (with prevalence declining from 20.6% to 18.6%) with some fluctuations. After 2015 there is some evidence of a worsening in psychological distress across surveys. Prevalence worsened notably among those aged 16-34 years after 2010 (all three surveys), and aged 35-64 years in Understanding Society and SHeS after 2015. In contrast, the prevalence declined in those aged 65+ years in Understanding Society after around 2008, with less clear trends in the other surveys. The prevalence was around twice as high in the most deprived compared with the least deprived areas, and higher in women, with trends by deprivation and sex similar to the populations overall. CONCLUSION: Psychological distress worsened among working-age adults after around 2015 across British population surveys, mirroring the mortality trends. This indicates a widespread mental health crisis that predates the COVID-19 pandemic.

Time trend analysis of social inequalities in psychological distress among young adults before and during the pandemic: evidence from the UK Household Longitudinal Study COVID-19 waves.

BACKGROUND: Despite concerns about mental health problems among those aged 16-24 in England, which social groups have been most at risk, both over the past decade and during the COVID-19 pandemic, remains unclear. METHODS: We examined trends in psychological distress among young adults 16-24 years old in England using data from the UK Household Longitudinal Study. Using longitudinal data as repeated cross-sectional waves, we examined differences over time in mean General Health Questionnaire (GHQ) scores from wave 1 (2009-2010) to wave 10 (2018-2019) and six COVID-19 waves collected between April and November 2020, by economic activity, cohabitation with parents, parental education, area deprivation, ethnicity, age and sex. RESULTS: Compared with 2009-2010, increases in GHQ scores in 2018-2019 were higher in women than men (2.1 vs 1.3), those aged 16-18 than aged 22-24 (2.6 vs 0.9), those from white UK group versus other ethnic minorities, and those out of the labour force (3.6) or employed part time (2.2) than those employed full time (0.8). Compared with 2018-2019, psychological distress in 2020 also further increased among young adults residing in the most deprived areas (4.1 vs 1.2 in the least deprived areas). In 2020, losing one's job or most of one's work hours was associated with higher psychological distress and attenuated the differences between deprivation quartiles by 17%. CONCLUSION: In England, inequalities in psychological distress among young adults may have changed and increased during the COVID-19 pandemic. Investing in opportunities for young adults, particularly in more deprived areas, may be key to improve population levels of mental health.
