Blood glucose and glycosylated hemoglobin levels of type 2 diabetes at different altitudes and different races in Yunnan Province / 中国医师杂志

ABSTRACT

Objective To investigate the effects of altitude,race,gender and age on blood glucose and glycosylated hemoglobin(HbA1 c) of type 2 diabetes.Methods A total of 410 patients with type 2 diabetes (T2DM) who resided at different altitudes in Jinghong,Kunming and Lijiang city for over 5 years and received antidiabetic treatment without adjustments for over 3 months were enrolled.To compare blood glucose,hemoglobin (Hb) and HbA1 c levels of T2DM among different altitudes,different races,different genders and different ages,The correlation between races and HbA1c was evaluated with Pearson's correlation analysis.Results No significant differences were observed in fasting blood glucose (FBG) (P =0.49,P =0.1,P =0.09,P =0.3),2 h postprandial blood glucose (2 h PBG) (P =0.33,P =0.4,P =0.7,P =0.1),and HbA1 c (P =0.47,P =0.28,P =0.2,P =0.07) levels between patients at different altitudes,different races,different genders and different ages.However,there were significant differences in Hb (P ＜0.01).There was no significant correlation between races and HbA1c levels(r =0.003,P =0.6).Conclusions There were effects of altitude,race,gender and age on hemoglobin of type 2 diabetes,but no effects on glycosylated hemoglobin.
