IIIS Discussion Paper No. 429

Height is widely used as an objective measure of health status. It is commonly used in the large body of research evaluating welfare trends in historic populations and the long-run impacts of childhood environment. However, few research papers have examined the extent, causes or consequences of stature loss in aging populations. This is surprising, as many studies rely on the assumption that height is fixed in late adolescence. Using repeated observations on objectively measured data from the English Longitudinal Study of Ageing (ELSA), we document that stature loss is an important phenomenon among older individuals, and demonstrate how the use of unadjusted height will dramatically overstate health improvements for younger birth cohorts in cross sectional data. We show that there is an absence of consistent
predictors of stature loss at the individual level. However, we exploit the panel element of the ELSA survey to show how deteriorating health and stature loss occur in tandem. While our analysis details the inherent bias of height measurements in older populations, we do not find that significant differences arise from the use of unadjusted height as an input in typical empirical health production function models.
