Precarious employment and associations with socio-demographic characteristics and self-reported health in Wales, UK.

Objectives: The study's aim was to explore the prevalence of precarious employment (PE) in Wales prior to the COVID-19 pandemic and examine associations with PE domains across socio-demographics and self-reported health.

Study Design: A cross-sectional design was used to explore the prevalence of PE in Wales prior to the COVID-19 pandemic, in February 2020.

Methods: Data were collected from a national household survey carried out in May/June 2020, with a sample of 1032 residents in Wales. PE was determined using the Employment Precariousness Scale. Associations between experiencing PE and socio-demographic/health characteristics were examined using Chi-squared tests and logistic regression models (multinomial and binary).

Results: Overall, before the pandemic, one in four respondents (26.5%) was in PE, with the most prevalent domains, wages, and disempowerment being experienced by at least 50% of respondents. Worse perceived treatment at work was twice as likely in those reporting pre-existing conditions (adjusted odds ratio [aOR]: 2.45 95% confidence interval [CI]: [1.33-4.49]), poorer general health (aOR: 2.33 95% CI: [1.22-4.47]), or low mental wellbeing (aOR: 2.81 95% CI: [1.34-5.88]). Those with high wage precariousness were three times more likely to report low mental wellbeing (aOR 3.12 95% CI [1.54-6.32]).

Conclusions: The creation and provision of secure, adequately paid job opportunities has the potential to reduce the prevalence of PE in Wales. Targeting such employment opportunities to those people currently unwell would have better population health gains.
