Printed in the Republic of Congo Prepared by Dr William Muhwava Consultant in Social Determinants of Health ACKNOWLEDGEMENTS This report was prepared by Dr William Muhwava for the Ministry of Health, Seychelles with financial and technical assistance from the World Health Organisation, the Regional Official for Africa. Dr Muhwava worked with a technical team comprising experts from various government departments that provided technical guidance throughout the whole process of producing this report. The team consists of Dr. Cornelia Atsyor-WHO Liaison Officer in Seychelles; Dr. Shobha Hajarnis- Director General of Public Health in Ministry of Health; Mr. Joachim Didon- Principal Statistician in Ministry of Health; Ms Bharathi Viswanathan-Project Manager in the Unit for Prevention and Control of Cardiovascular Disease of the Ministry of Health, Mrs Gin Michel Project Manager in the Cancer and Mental Health Unit, Mrs Julita Williams-Programme Manager of Diabetic Unit Ms Veraine Louis-Marie- Nutritionist in the Nutrition Unit of Ministry of Health and Mr Jean Malbrook-Health Economist in the International Cooperation Unit. We would want to thank the technical team led by Dr Bovet that has undertaken the three waves of the Heart Surveys. Most of the information we use on non- communicable diseases come from those studies. We acknowledge using a significant amount of their analyses and papers in the report and duly referenced their works in the respective sections. Any attempt at reanalysing data from the HEART studies would have been unnecessary duplication as they have exhaustively done so. However, where necessary, these analyses have been complemented by further analysis and evidence from other sources. In the same context, we would like to thank Dr Kam Ki Tang, and Dr Dennis Petrie, both of the University of Queensland who provided technical assistance in using the realization of potential life years (RePLY), a new method to measure health inequalities caused by conditions amenable to policy intervention and use this to identify health differences between sexes and age groups. This collaboration will continue as we interrogate more the data from Seychelles and show the applicability of the method in the study of health inequalities. Mr Joachim Didon deserves special mention as he assisted in identifying all the datasets that have been used in this report. The support we got from the Minister of Health, and Dr Jude Gedeon, Public Health Commissioner was immense. Lastly, we would want to thank Professor Davison Munodawafa of WHO AFRO for technical assistance during the whole process. Cancer, diabetes, and heart diseases are no longer the diseases of the wealthy. Today, they hamper the people and the economies of the poorest populations even more than infectious diseases. This represents a public health emergency in slow motion.
