Abstract

Abstract: Background: Mental ill-health is common with significant impact on individuals and services. Using healthcare records to identify poor mental health missed individuals who do not seek healthcare treatment. A screening questionnaire (General Health Questionnaire (GHQ)) can detect psychological distress. However, before considering implementing such a screening tool, we need to understand if it detects those at high risk of experiencing poorer outcomes. Hospital-based multimorbidity is a rising healthcare challenge. The aim was to assess the prevalence of psychological distress in mid-life and its influence on hospital-based multimorbidity by older age in the Aberdeen Children of the 1950s (ACONF) cohort. Methods: Prospective cohort study using ACONF. GHQ-4 was measured in mid-life from questionnaire. Multimorbidity (2 or more co-existing conditions) was measured using linked hospital records in older age (15 years after the questionnaire). The relationship between psychological distress (GHQ-4 score of 1 or more) and multimorbidity was assessed using logistic regression with adjustment for key life-course variables. Results: Of 5, 839 individuals (48% male, mean age 48), psychological distress prevalence was 20% and was associated with being female, lower childhood cognition, lower educational attainment, lower adult social class, unemployment, higher adult body mass index, smoking and alcohol misuse. In comparison to the asymptomatic reference group, the odds ratio for multimorbidity in older age in those with psychological distress was 2.2 (95% CI 1.8-2.7) in the unadjusted model. In the adjusted model this was 1.4 (95% CI 1.1-1.8). Conclusions: 1 in 5 individuals in the general population in mid-life had psychological distress. This was associated with hospital-based multimorbidity by older age. Intervening early could reduce costs to both individuals and healthcare services. The next step is research of the cost-effectiveness of population screening for psychological distress. Key messages: Psychological distress in mid-life is associated with hospital-based multimorbidity by older age. Screening for psychological distress early in life should be explored as an intervention to reduce costs to individuals and healthcare services.
