Life course measures of socioeconomic position and self reported health at age 50: prospective cohort study

Abstract

The Newcastle thousand families study is a prospective cohort study of all people born in May and June 1947 in Newcastle upon Tyne, UK.³ These people have been followed up to age 50 and data are available on SEP at birth (collected contemporaneously), age 25 and age 50 (both collected at age 50)—measured throughout, for consistency, as the registrar general’s social class (RGSC) of the head of household using the 1990 classification of occupations collapsed into either manual or non-manual social classes. LLSI, at age 50, was determined using the question: “do you have any long term illness, health problem or handicap which limits your daily activities in any way?”
