IntroductionThe exact causes of death in India are not known because autopsy studies are difficult to conduct due to religious considerations. There are rapid changes in diet and lifestyle amongst social classes causing changes in the pattern of risk factors and mortality. In the present study, we attempt to develop a verbal autopsy questionnaire based on medical records and interview of a family member, for the assessment of causes of death, social class, tobacco consumption and dietary intakes among urban decedents in north India.MethodsFor the period 1999-2001, we studied the randomly selected records of death of 2222 (1385 men and 837 women) decedents, aged 25-64 years, out of 3034 death records overall from the records at the Municipal Corporation, Moradabad. Families of these decedents were contacted individually to find out the causes of death, by scientist- administered, informed-consented, verbal autopsy questionnaire, completed with the help of the spouse and local treating doctor practicing in the appropriate health care region. Clinical data and causes of death were assessed by a questionnaire based on available hospital records and a modified WHO verbal autopsy questionnaire. Dietary intakes of the dead individuals were estimated by finding out the food intake of the spouse from 3-day dietary diaries and by asking probing questions about differences in food intake by the decedents. Tobacco consumption of the victim was studied by a questionnaire administered to family members. Social classes were assessed by a questionnaire based on attributes of per capita income, occupation, education, housing and ownership of consumer luxury items in the household. The diagnoses of overweight and obesity were based on the new WHO and International College of Nutrition criteria.ResultsCardiac diseases (23.4%, n = 520) including coronary artery disease (10%), valvular heart disease (7.2%, n = 160), diabetic heart disease (2.2%, n = 49), sudden cardiac death and inflammatory cardiac disease, each (2.0%, n = 44) were the most common causes of deaths as reported using the modified verbal autopsy questionnaire. Brain diseases including stroke (7.8%, n = 175) and inflammatory brain disease were reported amongst 1.9% (n = 42) victims.Thus, NCDs (37.0%, n = 651); circulatory diseases (31.2%, n = 695) including stroke and cardiac diseases, and malignant neoplasms (5.8%, n = 131) emerged as the most common causes of death. Injury and accidents (14.0%, n = 313) including fire, falls and poisonings were also common. Miscellaneous causes of death were observed amongst 8.5% (n = 189) of victims. Pregnancy and perinatal causes (0.72%, n = 15) were not commonly recorded in our study. Renal diseases (11.2%, n = 250), pulmonary diseases (22.3%, n = 495) and liver diseases (4.8%, n =107) were also commonly recorded causes of death. It is clear that causes of death related to various body systems can be more accurately assessed by the modified verbal autopsy questionnaire. Circulatory diseases as the cause of mortality were significantly more common among higher social classes (1-3) than in lower social classes (4 and 5) who died more often, due to infections. Death due to coronary disease, stroke, hypertension, diabetes and obesity were significantly more common among higher social classes 1-3 and among victims with higher body mass index (BMI) compared to social class 4 and 5 who had lower BMI.ConclusionsThis study indicates that causes of death, social class, tobacco and dietary intakes, can be accurately assessed by a modified verbal autopsy questionnaire based on medical records and by interview of family members. Circulatory diseases, injury-accidents and maligant diseases have become the major causes of death in India, apart from infections.
