Depression and Type A behaviour are important risk factors of death due to cardiovascular disease (CVD) and diabetes. Depression also predisposes deaths due to suicides. In the present study, we examine the association of endogenous depression with causes of deaths and accuracy of the questionnaire for diagnosis, among urban decedents in a lower middle income country.
We studied the randomly selected record1s of death of 2222 (1385 men and 837 women) decedents, aged 25-64 years, out of 3034 death records overall from the records at Municipal Corporation, Moradabad, India. All the families of these decedents could be contacted individually to find out the causes of death, by scientist/doctor administered, informed consented, verbal autopsy questionnaire, completed with the help of the spouse and local treating doctor practising in the appropriate health care region. Clinical data and causes of death were assessed by a questionnaire based on available hospital record and verbal autopsy questionnaire, suggested by WHO and International College of Nutrition (ICN). Decedents were classified into mild to moderate and severe depression based on available records and verbal autopsy questionnaire validated for this study by Agnieszka. The association of depression with causes of death was calculated by Mantel-Haesnzel Chi square test.
Several of the decedents had mild to moderate depression (n=153, 6.88%) (men 6.64 %, n=92; and women 7.28 %, n=61). The prevalence of severely depressed victims was similar among men (1.08%, n=15) women 1.67% (n=14) with a total of 1.3%(n=29). The total prevalence of depression was 8.19% (n=182). There was an overall increase in diabetes mellitus, hypertension, and CAD among decedents with depression and the trend was significant. The prevalence of depression showed a significant rising trend among decedents dying due to circulatory and suicidal causes of death, both among men and women. Multivariate logistic regression analysis after adjustment of age and body mass index revealed that hypertension and CAD and diabetes mellitus were strongly associated whereas depression and sedentary behaviour were weakly associated with risk of deaths due to CVDs. Social class 3 and 4 were not associated with risk of deaths due to CVDs and diabetes. Depression was an important risk factor of deaths due to CVDs and suicides.
The prevalence of depression was substantial among decedents dying due to various causes of death as revealed by the Agnieszka’s questionnaire. Depression may be accurately diagnosed as contributing risk factor among decedents dying due to circulatory diseases and suicides.Larger studies would be necessary to demonstrate the accuracy of the questionnaire in the diagnosis of depression and its association of with causes of death among decedents.

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."

Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."

Patrice Talaga

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."

Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."

Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."

Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."

Richard Reithinger
(Westat, USA)

"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."

"Open Access 'Chemistry' Journals allow the dissemination of knowledge at your finger tips without paying for the scientific content."

Sean L. Kitson
(Almac Sciences, Northern Ireland)

"In principle, all scientific journals should have open access, as should be science itself. Open access journals are very helpful for students, researchers and the general public including people from institutions which do not have library or cannot afford to subscribe scientific journals. The articles are high standard and cover a wide area."

Hubert Wolterbeek

"Open access journals are very useful for all scientists as they can have quick information in the different fields of science."

Philippe Hernigou
(Paris University, France)

"There are many scientists who can not afford the rather expensive subscriptions to scientific journals. Open access journals offer a good alternative for free access to good quality scientific information."

Fidel Toldrá
(Instituto de Agroquimica y Tecnologia de Alimentos, Spain)

"Open access journals have become a fundamental tool for students, researchers, patients and the general public. Many people from institutions which do not have library or cannot afford to subscribe scientific journals benefit of them on a daily basis. The articles are among the best and cover most scientific areas."

M. Bendandi
(University Clinic of Navarre, Spain)

"These journals provide researchers with a platform for rapid, open access scientific communication. The articles are of high quality and broad scope."

Peter Chiba

"Open access journals are probably one of the most important contributions to promote and diffuse science worldwide."

Jaime Sampaio
(University of Trás-os-Montes e Alto Douro, Portugal)

"Open access journals make up a new and rather revolutionary way to scientific publication. This option opens several quite interesting possibilities to disseminate openly and freely new knowledge and even to facilitate interpersonal communication among scientists."

Eduardo A. Castro
(INIFTA, Argentina)

"Open access journals are freely available online throughout the world, for you to read, download, copy, distribute, and use. The articles published in the open access journals are high quality and cover a wide range of fields."
