Prevalence and correlates of diabetes and its comorbidities in four Gulf Cooperation Council countries: evidence from the World Health Survey Plus.
The Gulf Cooperation Council countries are witnessing unprecedented changes due to fast economic development and population growth. The aims of this study were twofold: first, to estimate the prevalence of diabetes and its comorbidities; second, to examine the association of sociodemographic risk factors and healthcare service utilisation with diabetes. Data from the World Health Survey Plus (WHS+) from Kuwait, Oman, Saudi Arabia and the United Arab Emirates were used. The WHS+ is a nationally representative household survey of the adult population, conducted between 2008 and 2009. Both logistic regression and zero-inflated Poisson models were applied to examine the associations of risk factors, comorbidity and treatment with self-reported diabetes. The highest level of diabetes was observed in Kuwait, with 40.8% among the oldest age group. High body mass index, older age and low education were all associated with diabetes in all settings. High levels of comorbidity existed within the diabetic population. Over 50% of diabetics in all countries reported having at least one chronic condition. In Kuwait and Saudi Arabia, one in five diabetics reported having two or more comorbidities. Treatment prevalence was above 80% across all sociodemographic categories. The burden of diabetes, although high, is not uniform across populations in the four Gulf countries. Differential exposure to risk, such as unhealthy lifestyles, may be creating a disadvantage for certain populations and influencing the co-occurrence of chronic conditions. In response, a multifaceted and patient-centred approach is needed at all levels of healthcare to control and prevent non-communicable diseases.
