The inverse gradient between mortality and social position is well established. But how disease patterns and multimorbidity (having two or more long term conditions at the same time) impact on differential mortality rates is inconclusive: is it because disadvantaged groups acquire more or more lethal combinations of, diseases over their life course; or, simply, become ill at ages younger than more affluent groups?","overall_status":"Unknown","phases":[],"study_type":"OBSERVATIONAL","sponsor":"University College, London","enrollment":1300000,"countries":["United Kingdom"],"start_date":"2015-01-01","completion_date":"2017-01-01","last_update_date":"2015-11-20","source_url":"https://clinicaltrials.gov/study/NCT02609516","editorial_summary":"A registered study indexed because it matched monitored longevity research terms.
