The Sultanate of Oman has experienced an epidemiological transition over the last 4 decades with rising tide of non-communicable disease such as type-2 diabetes. This study aims to estimate the prevalence of prediabetes and explore the associated demographic, clinical and biochemical risk factors among a semi-urban Omani population. A semi-urban satellite town, Bidbid, located about 30 km west of the capital, Muscat, was selected as the study setting. The targeted participants were Omani adults (18 to 60 years old) who had resided in Bidbid municipality for at least 6 months prior to enrollment in the study. Using multistage random sampling, 1,600 Bidbid residents were invited to participate in the study. The study protocol gathered data on the socio-demographic and clinical backgrounds of the participants. Participants' impaired glucose tolerance (IGT) impaired fasting glucose (IFG) and cholesterol and triglyceride levels were then measured. The study surveyed 1,313 individuals (490 men and 823 women) out of 1,600 who had been invited to participate. The participation rate was higher among women than men (91.5% compared to 54.3%). A total of 459 individuals (35% of participants) were diagnosed as pre-diabetic by either the IGT or IFG test; 121 (9%) were pre-diabetic by virtue of both measurements. Male gender, advanced age and obesity were each independently associated with higher prevalence of pre-diabetes. Increased prevalence of pre-diabetes also correlated with the indices of hypercholesterolemia and dyslipidaemia. Pre-diabetes is a substantial health problem in Oman that may present a significant challenge to the national healthcare system in the near future. Customized interventions targeting groups with high risk of pre-diabetes, especially men, the elderly and the obese, are urgently needed.
