The UPHD I project was designed and implement by APHRC.  \n\nThe study on the migration, poverty and the wellbeing of older people is a longitudinal research project following up older people living in two slums of Nairobi, Kenya. The project is a partnership between University of Southampton, UK and the African Population and Health Research Centre (APHRC) located in Nairobi, Kenya. The overall aim of the study is to investigate the living arrangements and well-being of older people living in informal settlements and how these differ by migration status and socioeconomic circumstances. \n\n\n\nAlthough the overall aim of the study (UPHD I) was to investigate the living arrangements and well-being of older people living in informal settlements and how these differ by migration status and socioeconomic circumstances. \n\n\n\nThe specific objectives were to study:\n\n1.1 The poverty status, economic activity, demographic profile, living arrangements, and social support networks of older people; \n\n1.2 Understand the determinants of health and health-seeking behaviour among the older people;\n\n1.3 Examine the migration histories, migration intentions and linkages with place of origin of older urban slum dwellers;\n\n1.4 and to understand patterns of care and support in later life and how this is affected by increased mortality of economically active adults.","coll_dates":[{"start":"2006-01-11","end":"2010-12-14","cycle":""}],"nation":[{"name":"KENYA","abbreviation":"KEN"}],"geog_coverage":"Two informal settlements, Korogocho and Viwandani, in Nairobi City (the capital city) of Kenya.","analysis_unit":"The unit of analysis is the individual","universe":"The survey covered all de jure household members (usual residents), aged 50 years and above in the household","data_kind":"Sample survey data [ssd]","notes":"The scope of the Aging Survey includes:\n\n-Identification Information and Consent; Marital Status; Care and support; Links with place of origin; Work History and Benefits; Health care utilization;Health state descriptions - WHODAS 12 AND WHOQoL; Caring for Persons with prolonged illness; Social-cultural environment; Anthropometrics and biomarkers","study_scope":"The scope of the Aging Survey includes:\n\n-Identification Information and Consent; Marital Status; Care and support; Links with place of origin; Work History and Benefits; Health care utilization;Health state descriptions - WHODAS 12 AND WHOQoL; Caring for Persons with prolonged illness; Social-cultural environment; Anthropometrics and biomarkers"},"method":{"data_collection":{"data_collectors":[{"name":"African Population & Health Research Center","abbreviation":"APHRC","affiliation":""}],"sampling_procedure":"Two cohorts of older people were recruited.

Older people 50 years and older who were resident members of the HDSS at the time of the recruitment formed the sampling frame for the study. At the first recruitment (Cohort 1), 2,612 older people were resident in the demographic surveillance area. The second recruitment targeted older people who in-migrated (123) into the surveillance area between the January - September 2007, those who turned 50 years (242) as well as older people who were present in the first recruitment (392) but who contact could not be established.
