Objective To investigate the relationship between the fat intake and the morbidity of hyperglycemia(the fasting blood glucose over 6.1mmol/L, or the blood glucose one hour after the meal over 11.1mmol/L, or the blood glucose two hours after the meal over 7.8mmol/L, or the participants diagnosed diabetes previously) of middle aged and elderly people in Zhang Fang village, Fang Shan District, Beijing. Methods In 16^th July 2011, our nutrition department went to the Zhang Fang village Fang Shan District to do the free clinic. Totally 134 middle aged and elderly villagers were selected randomly. Our study was a cross-sectional study. We investigated the villagers about the diet intake, the life habit and disease history, measured the parameters of anthropometry and immediately glucose using Roche glucometer, and recorded the measure time. According to the glucose level, we categorized the villagers into hyperglycemia group and euglycemia group. According to the median of fat intake, we separated the villagers into relatively high fat group and relatively low fat group. We analyzed the differences between these groups, then used Logistic regression to analyze the indexes which can influence the blood glucose. Result The morbidity of hyperglycemia in our survey was 47.01%. The morbidity of hyperglycemia in relatively high fat group was significantly higher than that in relatively low group. The intake of protein, dietary fiber, total energy and mixed dietary glycemic load in relatively high fat group were significantly higher than those in relatively low group group. The fat intake, energy intake, BMI and body fat in hyperglycemia group were significantly higher than those in euglycemia group. Logistic regression showed that high fat intake and increased BMI can raise the morbidity of hyperglycemia. Conclusion The morbidity of hyperglycemia of middle aged and elderly people in Zhang Fang Village was in high level. This phenomenon is associated with the high fat intake and increased BMI.
