Changing profile of disease contributing to mortality in a resettlement colony of Delhi.

BACKGROUND

The past decade has seen a decline in the disability-adjusted life years (DALYs) contributed by communicable diseases while lifestyle changes and rapid urbanization have led to an increase in DALYs contributed by non-communicable diseases. We studied the causes of death in a low socioeconomic area over 11 years to help identify changes in the pattern of disease.

METHODS

We did this study in Gokulpuri, a resettlement colony in East Delhi. All deaths occurring from 1994 to 2004 were analysed using a verbal autopsy questionnaire completed by trained health workers during their home visits in the area.

RESULTS

A total of 515 deaths occurred during the period; 340 in men (66%) and 175 in women (34%). The six commonest causes of death were tuberculosis (24.8%), chronic obstructive pulmonary disease (11.6%), pneumonia (8.7%), accidents and poisoning (8.6 %), coronary heart disease (8.2%) and cancer (4.6%). The age-specific mortality rate was highest among people > 45 years of age. The cause-specific mortality rate due to communicable diseases showed a decline while that due to non-communicable diseases showed a rising trend in all age groups.

CONCLUSION

Our study shows the coexistence of communicable and non-communicable diseases in a low socioeconomic area with a rising trend in non-communicable diseases. Surveillance for risk factors of non-communicable diseases should be done even in predominantly low socioeconomic areas. The coexistence of communicable and non-communicable diseases and the increase in non-communicable diseases among the economically deprived sections of our society suggest the need to re-prioritize components of healthcare among these sections.
