“…6 Depending on the health outcome (eg, psychological or physical health), the study design and sample (eg, many earlier studies are based on non-representative occupational cohorts such as GAZEL and Whitehall), the country considered (USA or Europe), its timing, and the reasons given for leaving work (eg, voluntary, ill health, etc), retirement has been found to have beneficial, detrimental or no effects on health. [7][8][9][10][11][12][13][14][15] The evidence largely suggests that retirement is associated with an improvement in psychological health and wellbeing, 7-9 15 but results are less consistent for physical health. [9][10][11][12][13][14][15] However, working post-SPA is a relatively recent trend and so, until now, few studies have focused on the health consequences of continuing work past statutory retirement age while accounting for both health selection and labour market attachment prior to SPA.…”
