Researchers at Weill Cornell Medicine-Qatar (WCM-Q) have adapted an international measure used to assess the prevalence of metabolic syndrome - a serious condition linked to diabetes, heart disease and stroke to the Qatari population.
Metabolic syndrome is diagnosed by the presence of three or more of five risk factors: abdominal obesity, raised blood pressure, raised fasting blood glucose, raised levels of triglycerides (fatty acids present in the blood), and reduced levels of high-density lipoproteins so-called 'good' cholesterol.
By analyzing large amounts of data collected by earlier health surveys conducted in Qatar, the WCM-Q team found that waist circumference was the best predictor of the presence of the other determinants of metabolic syndrome. However, the research team, led by Dr Ravinder Mamtani, decided to go further and adapt the international waist measurement criteria set out by the International Diabetes Federation (IDF) to create a population-specific set of parameters for Qatari nationals.
Dr Mamtani, Senior Associate Dean for Population Health and Capacity Building at WCM-Q, said:"Because of a lack of data in the Middle East, the IDF actually recommends using European waist measurement cut-off points for assessing metabolic syndrome in Middle Eastern populations."
Sheikh Dr Mohamed H al Thani, director of Public Health at the Ministry of Public Health and a principal member of the research team, said:"We realised that there is some very good data available in Qatar. So, we decided to look at it closely and devise a set of waist measurement parameters for assessing metabolic syndrome that is tailored specifically to the Qatari population."
"This has given us a better understanding of the prevalence of metabolic syndrome among Qataris. We believe it will help health professionals to address more accurately the growing problem of obesity and related conditions, which is a very pressing concern in the region."
The researchers used sophisticated statistical methods to analyse data on 2,496 Qatari citizens collected in the Qatar National STEPwise Survey in 2012 by the Supreme Council of Health (now the Ministry of Public Health). The results allowed the researchers to determine that a waist circumference for Qatari men of 102cm or more, and of 94cm or more for Qatari women, was the best predictor of the presence of the other determinants of metabolic syndrome. That compares to the European cut-off points of 94 cm and 80 cm respectively that are currently used by the IDF for assessing Middle Eastern populations.
Using the Qatari-specific cut-off points, the WCM-Q team found that approximately 28 percent of Qataris satisfy the criteria for metabolic syndrome a considerably lower level than the estimate of 37 percent calculated using the European cut-off points recommended by the IDF.
Dr Sohaila Cheema, Assistant Professor of Healthcare Policy and Research at WCM-Q, said:"This study is important because using cut-off points that are not appropriate to the ethnic group being studied risks skewing the results and giving an inaccurate picture of the true prevalence of metabolic syndrome. Each ethnic group has unique characteristics, so we feel that if you have good data for a group, it is very beneficial to use it to determine more suitable cut-off points, which is what we have managed to do with this project."
The WCM-Q team worked in partnership with researchers from Qatar's Department of Public Health, New York Medical College, and the European Institute of Oncology in Milan, Italy on the study. The paper is titled 'Prevalence and determinants of metabolic syndrome in Qatar: results from a National Health Survey' and has been published in the prestigious medical journal BMJ Open. The total sample size of 2,496 individuals aged 18-64 comprised 1,053 men and 1,443 women.
The analysis of the data also revealed that people with lower levels of educational attainment were more likely to have metabolic syndrome, as were people who reported lower levels of physical activity.
Other authors of the paper include Dr Al Anoud Mohammed al Thani, Manager of Non Communicable Diseases, Dr Walaa F al Chetachi, Shamseldin A H Khalifa, Dr Ahmad O H Bakri of the Department of Public Health, Dr Badria A al Malki from Primary Health Care Corporation, Dr Javaid Sheikh, Dean of WCM-Q, Dr Albert Lowenfels of the Department of Surgery and the Department of Family Medicine at New York Medical College and Patrick Maisonneuve of the European Institute of Oncology, Milan, Italy.
