Summary There is considerable heterogeneity in the variables that we have studied and in disease outcomes, across locations (urban-rural-urban slum), gender and region (centre) Urban-rural risk transitions generally follow patterns of development. In Kerala, there is evidence of a reversal of the transition with the rural population. Dietary data needs to analysed in most centres – this when available will help us understand some of the changes that we have observed across centres and locations Non responder data and issues of response bias are being analysed
CHALLENGES / ISSUES OF THE STUDY Subjects in rural areas / slums unwilling to participate due to loss of daily wages Responder burden due to the length of questionnaires Working men unavailable during the day / particular seasons. No perceived benefits in some groups slums / urban areas. Takes 45 mins to enter one subjects data in the data entry system.
