Abstract
OBJECTIVE: To investigate the prevalence rates of diabetes and pre-diabetes among migrating population in Inner Mongolia. METHODS: Using stratified cluster sampling on different industries. Each industry would have the same sample size. Questionnaire survey was performed together with anthropometric data gathered and laboratory tests completed. RESULTS: The prevalence rates of diabetes and impaired glucose regulation (IGR) among the migrating population in Inner Mongolia were 12.5% and 12.8% with the age-standardized rate as 9.9% and 9.9%. The prevalence of diabetes increased significantly along with the increase of age among both males and females (χ² = 11.162, P = 0.001), but was significantly higher in males. The prevalence of IGR in females was significantly higher than in males. The prevalence of diabetes among the construction industry workers was 19.2%, which was the highest among all the industries. The prevalence of diabetes was higher in the inter-province pre-migrating group, while the prevalence of IGR was increasing along with the duration of migration in the intra-province migration group with the trend as χ² = 9.989, P = 0.002. CONCLUSION: The prevalence of diabetes among the migrating population in Inner Mongolia seemed to be high, close to the level of urban residents. The prevalence rates of diabetes in the population of middle-aged and aged population as well as workers at the construction industry were higher than that in the other populations. The prevalence of diabetes and IGR among the migration population were related to the area where the migration population the in-coming areas Inter-provincial migration had a higher contribution to the prevalence of diabetes.
