ABSTRACT
Objective To evaluate the effect of community management of diabetic patients with hypertension in Beijing Cuigezhuang community in last three years.Methods A community diabetic management program was started from 2007 in Beijing Cuigezhuang community.Three hundred and seventy six patients who participated in the program for more than 3 years were enrolled in the study, including 196 with type 2 diabetes mellitus (T2DM) only (DM group) and 180 with T2DM and hypertension (DMH). The control rate of blood glucose, blood pressure, lipids and the comprehensive control rate were compared between two groups after 3-year intervention.Results There were no significant differences in age, gender ratio, course of diabetes, education background, monthly income and the history of stoke between two groups;while prevalence of dyslipidemia in DMH group was significantly higher than that in DM group [41.7%(75/180) vs.24.5%(48 196),χ2 =11.938,P=0.001].Compared with the baseline data, the types of antidiabetic drugs used were not significantly changed in two groups after 3-year intervention ( DM group:1.32 ±0.81 vs.1.31 ±0.93, t=-0.155, P=0.877, DMH group:1.43 ±0.72 vs.1.48 ±0.82, t=0,831, P =0.407) .The types of antihypertensive drug in DMH group were significantly decrease. (1.12 ±0.77 vs.1.25 ±0.45, t=2.484, P=0.014), while the rate of statins usage in DM group was significantly increased [13.3%(26/196) vs.5.1%(10/196),χ2 =7.830, P=0.005].The hemoglobin A1c (HbA1c) levels in DM group was decreased [(7.4 ±1.5)% vs.(7.8 ±2.1)%, t=2.586, P=0.011].The systolic pressure [(129 ±12) mmHg (1 mmHg=0.133 kPa) vs.(133 ±16) mmHg, t=3.503, P=0.001] and the diastolic pressure [(80 ±8) mmHg ratio (82 ±10) mmHg, t=2.436, P=0.016] in DMH group were significantly declined. The average LDL-C level [ DM group: ( 3.0 ± 0.9) mmol/L vs.(3.2 ±1.0) mmol/L, t =2.165, P=0.032; DMH group (2.9 ±1.0) mmol/L vs. (3.2 ±1.1) mmol/L, t=3.210, P=0.002] were also significantly decrease.Compared with the baseline, the comprehensive control rates of blood glucose, blood pressure and lipid level were increased in both groups [DM group:9.7% (19/196) vs.6.1%(12/196),χ2 =1.716, P=0.190, DMH group 13.9%(25/180) vs.5.0%(9/180),χ2 =8.315, P =0.004] .Conclusions The community management program is effective for improvement of comprehensive control rates of blood glucose, blood pressure and blood lipids in diabetic patients with hypertension in Beijing Cuigezhuang community.
ABSTRACT
Objective To observe the effect of long-term intensive glucose control therapy on diabetic retinopathy in outpatients with type 2 diabetes mellitus.Methods Forty-nine patients with type 2 diabetes mellitus were randomly assigned to participate in the trial from 2002 to 2007,receiving either intensive (24 cases) or standard glucose control (25 cases).The patients were examined by the same ophthalmologists to identify any new diabetic retinopathy (DR).After 5 years of intensive glucose control,all of the patients were asked to attend our clinic every 6 months,but no attempts were made to maintain their previously assigned therapies.Hemoglobin A1c (HbA1 c) was measured regularly.In November of 2009,a retinal examination was carried out by the same ophthalmologist who worked in the trial.The visual acuity,lens,vitreous body and fundus were examined after pupil dilation to identify diabetic retinopathy (DR).Fundus fluorescein angiography and retinal laser photocoagulation were carried out when necessary.Results In the second year after enrollment in the trail,the median HbA1c level of the intensive-therapy group was significantly lower than that of the standard-therapy group [(6.3 ± 0.6) ％ vs.(7.2 ± 1.2) ％,t =2.09,P ＜ 0.05],and was maintained in a controlled level throughout the following 4 years.During the post-trial monitoring,no new case of of macula edema or diabetic associated blindness occurred in either intensive or standard-therapy group,the whole occurrence of micro-aneurysms,fundus hemorrhage,as well as those who needed retinal laser photocoagnlation and lowering in visual acuity in intensive-therapy group was lower than that in the standard-therapy group (3 vs.14,1 vs.7,2 vs.4,3 vs.11,respectively ;9 vs.36,totally,x2 =4.719,P ＜ 0.05).During the first post-trial monitoring,there was no difference in median HbAlc level between intensive-therapy group and standard-therapy group [(7.2 ± 1.1) ％ vs.(7.3 ± 1.3) ％,t =0.25,P =0.806],which was sustained in the following years.In the trail,no new case of fundus hemorrhage or diabetic associated blindness occurred in intensive-therapy group during the five-year period of therapy.Number of new episodes of micro-aneurysm,macula edema were less in intensive-therapy group than that in standard-therapy group,number of new episodes of lowering in visual acuity,and those who needed retinal laser photocoagnlation,were significantly less in intensive-therapy group than that in standardtherapy group(15 vs.25,4 vs.23,Z =-4.459,P ＜ 0.05) during five-year follow-up.Conclusions The benefit of reduced incidence of diabetic retinopathy in intensive glucose can be maintained because of the legacy effect.
ABSTRACT
Objective To investigate the prevalence of dyslipidemia in subjects with type 2 diabetes mellitus in Beijing urban communities.Methods Total 3316 subjects with type 2 diabetes (age 20-80 years) were recruited from 15 urban community health centers in Beijing using a multi-stage random sampling approach.Dyslipidemia was diagnosed according to Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults:2007 version.Results Among 3316 diabetic subjects (1329 malesand 1987 females),75.6％ (2506/3316) had dyslipidemia,the prevalence was 72.5％ (964/1329)in men and 77.6％ (1542/1987) in women.The prevalence of hypertriglyceridemia and hypercholesterolemia was 41.9％ (1388/3316) and 48.1％ (1595/3316),respectively.31.5％ (1043/3316) subjects had high levels of low-density lipoprotein cholesterol (LDL-C) and 21.2％ (703/3316) had low high-density lipoprotein cholesterol (HDL-C).Among all subjects with dyslipidemia only 22.9％ (575/2506) took hypolipid agents.The overall blood lipid control rates of triglyceride (TG),total cholesterol (TC),LDL-C and HDL-C in 1393 subjects with dyslipidemia history were 48.0％ (669/1393),17.4％ (242/1393),30.9％ (430/1393) and 75.8％ (1056/1393),respectively.Diabetics with dyslipidemia had higher body mass index,waist circumference,blood pressure,plasma glucose and hemoglobin A1c.The prevalence of dyslipidemia in the overweight and uncontrolled-glucose group were 79.0％ (1678/2125),78.9％ (1756/2227),respectively.Logistic regression analysis showed that gender,age,body mass index and hemoglobin A1c were associated with dyslipidemia.Conclusions The prevalence of dyslipidemia in diabetic subjects in Beijing urban communities is high and less than one quarter patients take hypolipid agents.Age,body mass index and hemoglobin A1c are the risk factors of dyslipidemia in type 2 diabetic patients.
ABSTRACT
Objective To investigate current status of use of oral hypoglycemic drugs and insulin among adult patients with type 2 diabetes mellitus (T2DM) in urban community of Beijing.Methods In total,3297 T2DM patients aged more than 20 years from 15 urban communities of Beijing were studied.Their body weight,height,fasting plasma glucose level and glycosylated hemoglobin Alc (HbAlc) were measured.A door-to-door questionnaire survey on use of oral hypoglycemic drugs and insulin was conducted for them.All the T2DM patients surveyed were divided into four groups based on their received intervention.Results ①Of 3279 T2DM patients,454 (13.8％) received lifestyle intervention,971 (29.5％) used only one oral hypoglycemic drug,1179 (35.7％) with combined oral hypoglycemic drugs,and 693(21.0％) with insulin.②There was significant difference in average HbAlc among the four groups of T2DM patients with lifestyle intervention,only one oral hypoglycemic drug,combined oral hypoglycemic drugs,and insulin,with HbAI c of (7.0 ± 1.9) ％,(7.1 ± 1.5) ％,(7.4 ± 1.5 ) ％,and (7.5 ± 1.5 ) ％for them,respectively ( F =15.1,P ＜ 0.01 ).Proportions of the T2DM patients with HbAlc equal to or higher than 7.0％ were 32.2％,39.4％,52.1％ and 59.5％ for the four groups,respectively ( x2 =117.7,P ＜ 0.01 ).③In the T2DM patients with lifestyle intervention,32.2％ (146/454) of them with HbA1 c equal to or higher than 7.0％ were untreated with any oral hypoglycemic drug.In those with only one oral hypoglycemic drug,39.4％ (383/971) of them with HbAlc equal to or higher than 7.0％ were not treated with combined oral hypoglycemic drugs and/or insulin.In those with combined oral hypoglycemic drugs,52.1％ (614/1079) of them with HbAlc equal to or higher than 7.0％ were not received combined insulin treatment.④ Fasting plasma glucose level,treatment strategies,postprandial 2-h blood glucose level and length of the illness were independent risk factors for HbAlc level equal to or higher than 7.0％,with odds ratio (OR) of 1.757,1.256,1.175 and 1.031,respectively.⑤ In 2843 T2DM patients with oral hypoglycemie drugs and/or insulin treatment,1494 (52.6％ ) received biguanides and 693 received (24.4％ )insulin,respectively.Conclusions More than half of adult patients with T2DM do not meet the target of glycemic control of HbAlc less than 7.0％ in urban communities of Beijing,due to not active use of oral hypoglycemic drugs,and not timely adoption of combined use of oral hypoglycemic drugs and insulin therapy.
ABSTRACT
Objective To study clinical characteristics of type 2 diabetic(T2D)patients with metabolic syndrome(MS)and its components in Beijing urban communities.Methods Totally,3295 T2D patients involved in a combined prospective diabetic management study from 15 urban communities in Beijing were classified as four groups, according to 2004 Chinese Diabetes Society's definition of MS, i. e, isolated T2D, T2D with one component of MS, T2D with two components of MS and T2D with three components of MS. Their clinical characteristics were analyzed. Results ( 1 ) Among 3295 T2D patients, 155 (4. 7% )were isolated T2D, 107 (32.6%) T2D with one component of MS, 1386 (42.1%) T2D with two components of MS and 679 (20.6%) T2D with three components of MS, with an overall 62.7% (2065/3295) of T2D patients complicated with MS. (2) In these T2D patients, the more components of MS they had, the higher body mass index (BMI), waist circumference, waist to hip circumference ratio (WHR),systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting serum levels of insulin and triglyceride (TG) and the lower level of high-density lipoprotein-cholesterol (HDL) were presented (P <0. 01 ). (3) Percentage of isolated T2D in women increased from 49. 0% (76/155) to 61.9% (420/679)of those with three components of MS ( P < 0 01 ), with increasing of components of MS. (4) Multiple logistic regression analysis showed that BMI, history of hypertension, decreased HDL, increased TG,increased blood pressure, all were risk factors for T2D patients complicated with MS. Conclusions Among T2D patients in urban communities of Beijing, 95.3% (3140/3295) of them complicated with one or more components of MS, and 61.9% (420/679) of them complicated with MS. So, community diabetic management must be implemented in an all-round way, including control of blood pressure, blood lipids,body weight and so on, in addition to control of blood sugar.
