A Population-Based Screening of Type 2 Diabetes in High-Risk Population of Yasuj, Iran

Article excerpt

INTRODUCTION

The prevalence of diabetes has increased during the last two decades in countries with low and middle income (1). This trend, which is almost completely due to type 2 diabetes, is expected to rise (2). The rise in the prevalence of type 2 diabetes will increase the likelihood of patients at risk of serious diabetes-related complications. Type 2 diabetes increases the risk of myocardial infarction two times and the risk of having a stroke two to four times. Furthermore, type 2 diabetes is one of the leading causes of blindness, limb amputation, and kidney failure (3-4).

The 2010 global diabetes prevalence among adults aged 20-79 years is estimated at 6.4%, affecting 285 million adults. Between 2010 and 2030, the adults with diabetes are expected to rise by 70% and 20% in developing and developed countries respectively (5). Environmental and lifestyle factors are among the main causes of the dramatic increase in the prevalence of type 2 diabetes (6-7).

The associations between body mass index (BMI), lipids, hypertension, smoking, physical inactivity, low education, dietary patterns, family history and specific genes with type 2 diabetes have been documented (8-11). The Middle East is expected to bear the highest increases in the absolute burden of diabetes in the coming decades. This increase is anticipated to affect the economically-productive 45 to 64 years old individuals (12).

The diabetes mellitus (DM) is the main cause of a common disease with increasing incidence and a variable geographical prevalence in Iran. A recent study reported 9.8% prevalence in the highly-urbanized capital of Iran, Tehran (13). The prevalence of DM in the Isfahan Healthy Heart Program was reported at 6.7% and 5.3% in urban and rural areas and 5.4% and 7.1% in males and females respectively (14). Crude prevalence of diabetes and age-adjusted prevalence were reported at 13.4% and 11% respectively in Booshehr while prevalence at Yazd was reported at 16.3% (15).

The prevalence of diabetes in Iran is estimated at 7.7% for adults aged 25-64 years, affecting 2 million individuals, where only one-half are undiagnosed. Furthermore, an additional 16.8% or 4.4 million of adults have been reported to have impaired fasting glucose (IFG) (16). The prevalence of type 2 diabetes by systematic review between 1996 and 2004 in those aged >40 years has been estimated at 24% in Iran and increases by 0.4% with each year after 20 years of age (17). The complications associated with diabetes can be prevented by early diagnosis, intense monitoring, and proper treatment. Diabetes is a major concern, and both diabetes and public health organizations worldwide have expressed the need for screening in asymptomatic individuals (18,19).

No representative population-based study has been undertaken to estimate the prevalence of diabetes and risk factors in the Kohgiloyeh and Boyerahmad province located in southwestern Iran. This study was carried out to estimate the prevalence of the undiagnosed DM and IFG in high-risk population and to examine their relationship with lifestyle, social and anthropometric features, and other risk factors.

This community-based study was approved by the Technology and Research Council of Kohgiloyeh and Boyerahmad province and covered the period of 2009-2010.

MATERIALS AND METHODS

Study subjects

The target population comprised 30-65 years old residents of the western suburbs of Yasuj. All individuals were screened in the survey, and those at high risk were included in the study.

Field survey

In total, 86 team members, mostly volunteer medical university students were involved in the field work. At least 2 days before the study, team members attended a training course covering specific local arrangements, completion of the questionnaire, anthropometric, physical, and blood pressure measurements. Teams were supervised by healthcare providers. …
