儿童2型糖尿病和糖调节异常筛查方案的研究 总被引:3,自引:0,他引:3
目的评价及比较在不同特征人群中进行2型糖尿病(T2DM)和糖调节异常(IGR)筛查的效果及成本,优化和推荐儿童青少年T2DM筛查方案。方法采用分层整群随机抽样方法获取19 593例北京市中小学生,用空腹指末梢血糖(FCBG)对其进行T2DM和IGR筛查,FCBG异常者(≥5.6 mmol·L-1)采用1999年WHO口服葡萄糖耐量试验标准进行诊断。并参照美国糖尿病协会建议儿童青少年T2DM筛查的高危对象标准和Dean提出的诊断标准进行T2DM的分型诊断。将研究人群分为一般人群、超重/肥胖和肥胖组,分别计算回访率、血糖异常阳性率、直接医疗成本和确诊每例成本,根据成本 效果推荐儿童青少年T2DM筛查方案。结果一般人群组,FCBG异常者回访率为47.97%(225/469),超重/肥胖和肥胖组FCBG异常者回访率分别为59.29%(83/140)和68.00%(51/75),差异有统计学意义。一般人群组T2DM/IGR确诊率最低,为1.67/1 000例;总花费11.21万元和确诊每例T2DM/IGR的花费0.35万元,最高。肥胖组T2DM/IGR确诊率最高,为8.09/1 000例;总花费1.62万元和确诊每例T2DM/IGR的花费0.11万元,最低,较一般人群组分别下降85.55%和68.57%。超重/肥胖组介于两者之间。肥胖、超重/肥胖与一般人群组相比,肥胖组有2例T2DM(33.33%,2/6)漏诊,超重/肥胖组没有T2DM 漏诊。建议在超重/肥胖组中进行T2DM和IGR筛查。进一步选择除超重/肥胖外,与T2DM相关的危险因素(黑棘皮病、T2DM家族史和青春期),随调查对象具有危险因素数量的增加,患病危险性增加,筛查依从性增高,T2DM/IGR确诊率升高,筛查总成本和每例成本降低,但是从调查对象具有3个或以上危险因素开始,对T2DM/IGR筛查敏感度下降,与在一般人群组筛查相比,在4个危险因素人群中进行筛查,将有83.33%的T2DM得不到确诊。结论 本大样本研究以成本 效果分析说明:在儿童中符合健康经济学的T2DM筛查方案是在达到超重标准,同时具有1个以上危险因素(黑棘皮病、T2DM家族史和青春期)儿童青少年中进行目的性筛查。 相似文献

过去认为在儿童1型糖尿病(T1DM)中多以体型消瘦为主, 超重、肥胖较少见, 因此重视程度不高。但近年随着儿童T1DM患病率的增高, 其超重和肥胖率也出现增长趋势, 这不仅影响患儿生长发育, 还可能增加其并发症的发生风险, 影响病情预后, 故现已成为T1DM长期管理中的一个新问题。现就T1DM儿童在随访中出现超重、肥胖的影响因素进行综述, 以提高临床对T1DM患儿超重、肥胖的重视, 做好对有风险因素群体的监测, 尽早给予关注和干预, 优化其治疗方案。 相似文献

儿童糖尿病主要为儿童1型糖尿病(T1DM),根据我国大中城市的大样本纵向调查,其年发病率增幅约为世界平均增幅的3倍,5岁以下儿童增幅较高,提示我国儿童T1DM低龄化趋势。T1DM的病因机制复杂,遗传易感和环境因素促发是其发病的主要原因。年幼起病、长病程、血糖控制欠佳除导致糖尿病慢性并发症高发外,还影响患儿精神运动发育。药物治疗、血糖监测、健康教育、运动和营养管理是儿童T1DM良好血糖控制的根本举措。人工胰腺、干细胞胰岛分化与移植、免疫干预未来有可能从根本上改善未来T1DM的治疗和预后。 相似文献

Objective: To investigate the prevalence of celiac disease (CD) in a cohort of type 1 diabetes mellitus (T1DM) children and adolescents at the time of clinical diagnosis and to evaluate the screening procedure and possible role of human leukocyte antigen (HLA)-DQ during a 5-yr follow-up.
Research design and methods: The study group was a cohort of 300 newly diagnosed T1DM children and youths younger than 20 yr followed for 5 yr at six clinical centers for pediatric diabetes in the region Skåne in Sweden. Immunoglobulin A endomysium antibodies were used to screen the patients annually to be considered for an intestinal biopsy. All patients were analyzed for HLA-DQA1-B1 genotypes.
Results: While 0.7% (2/300) already had a diagnosed symptomatic CD, an additional 3% (10/300) had silent CD at the diagnosis of T1DM. During follow-up, another 6% (17/300) developed CD as follows: 10 after 1 yr, 5 after 2 yr, 1 after 3 yr, and 1 after 5 yr. Therefore, the cumulative frequency of CD confirmed by intestinal biopsies was 10% (29/300). HLA genotypes among T1DM patients developing CD were not different from those among patients with T1DM alone.
Conclusions: Our study confirmed the low prevalence (0.7%) of diagnosed symptomatic CD at the time of clinical diagnosis but document by screening an increasing prevalence of silent CD during a 5-yr follow-up to reach an overall prevalence of 10%. We suggest that children with T1DM should be screened for CD at the onset of T1DM and annually for a minimum of at least 2 yr. HLA genotypes among T1DM patients developing CD were not different from those among patients with T1DM alone. 相似文献

Until recently, most children with diabetes mellitus had type 1 diabetes (T1DM). The prevalence of type 2 diabetes (T2DM) is on the rise in North America, especially in risk populations such as the American Indians. Few epidemiological data on the incidence of the disease exist in Europe. In a prospective population-based epidemiological study, all newly diagnosed cases of diabetes mellitus in patients under 15 years of age were registered nation-wide in Austria between 1999 and 2001. Differential diagnosis (according to the American Diabetes Association diagnostic criteria) was based on clinical case definition. During the 3 years of the study period, 529 cases of DM <15 years were documented, of which 510 were clinically assigned to T1DM (271 boys, 239 girls) resulting in an incidence rate of 12.4/100,000. In the same network, eight cases were diagnosed as T2DM (one boy, seven girls) and two cases with an atypical form of T2DM (two girls). The age of onset of T2DM was 12–15 years and all patients were overweight (body mass index >90th percentile).The calculated incidence for T2DM <15 years in Austria was 0.25/100,000. Conclusion: at present, type 2 diabetes mellitus is rare but exists in children aged under 15 years in Austria. Follow-up of this registration will help to describe the secular trend.Abbreviations

Children with suspected type 1 diabetes mellitus (T1DM) should have same day referral to a paediatric diabetes team. 99 children (54 male; median age 10.5 years, range 0.9-15.9 years) were diagnosed with T1DM at our hospital between January 2004 and June 2007. 27 (27.2%) presented in diabetic ketoacidosis (DKA). 37 (37.3%) required hospital admission, while the rest had ambulatory management. In 21 (21.2%) children, diagnosis was delayed >24 h (median 3.0 days, range 1-14 days) due to missed diagnosis at the local hospital (four) or by the general practitioner (seven), arranging a fasting blood glucose test (nine) and outpatient appointment requested via fax (one). Children with delayed diagnosis presented more frequently in DKA (52.3% vs 20.5%, p<0.01), with a higher median presenting HbA1c (12.3% vs 10.9%, p<0.05). There were no differences in age and sex between the delayed diagnosis and immediate referral groups. Healthcare providers need to be aware of the importance of immediate referral of children newly diagnosed with T1DM. 相似文献

Objective: To assess the prevalence of type 2 diabetes mellitus (T2DM) and maturity onset diabetes of the young (MODY) in children and adolescents aged 0−20 yr in Baden-Württemberg (BW), Germany, and to compare our results with those from other European countries.
Methods: Our study involved every children's hospital (n = 31), each diabetologist in private practice (n = 122), and every internal medicine unit (n = 164) in BW. A written questionnaire and a telephone survey were used to identify children with T2DM and MODY who had been examined at any of these institutions between 2004 and 2005. Population data were drawn from the national census of 1987 and the subsequent annual updates.
Results: The prevalence of T2DM for the age range from 0 to 20 yr is 2.30/100 000, whereas the prevalence of MODY in the same age range is 2.39/100 000. The median age of patients with T2DM was 15.8 yr, and 13.9 yr for MODY patients. The majority of patients with either T2DM or MODY were treated in children's hospitals and by consultant diabetologists. A molecular genetic analysis was done to substantiate the clinical diagnosis in less than half of the recruits (14.3% of T2DM and 44.8% of MODY patients).
Conclusions: The prevalence of T2DM and MODY is considerably lower than the prevalence of type 1 diabetes. Type 2 diabetes thus continues to be a rare disease in children and adolescents in Germany, as is also the case in other European countries. 相似文献

Background: The association between celiac disease (CD) and type 1 diabetes mellitus (T1DM) is well known. Up to now, CD prevalence in children and adolescents with T1DM in Serbia has not been reported. The aim of the present study was to determine CD prevalence and its clinical manifestations in patients with T1DM. Methods: One hundred and twenty‐one patients (70 girls, 51 boys; mean age, 10.8 years) with T1DM (mean duration of diabetes, 3.4 years) and 125 control group participants (75 girls, 50 boys; mean age, 10.4 years) were tested for CD on tissue transglutaminase antibodies (tTG). In seven serologically positive T1DM patients endoscopic small bowel biopsies were taken and examined on histopathology. In all patients with CD and T1DM age, duration of T1DM, height for age, body mass index, glycosylated hemoglobin and clinical symptoms were noted. Results: Nine patients with T1DM were positive on IgA tTG antibodies. In seven of them small bowel biopsy was performed, and all were proven to have CD on histopathology. The prevalence of biopsy‐proven CD in children and adolescents with T1DM was significantly higher in the study group compared to controls (5.79%. vs 0.8%, P < 0.05). Conclusion: The significantly higher prevalence of CD in children with type 1 diabetes, in accordance with the large volume of data published in the literature, underlines the need for yearly screening of CD in patients with diabetes in order to promptly start a gluten‐free diet when appropriate. 相似文献

Vitamin D is synthesised in the skin through the action of UVB radiation (sunlight), and 25‐hydroxy vitamin D (25OHD) measured in serum as a marker of vitamin D status. Several studies, mostly conducted in high latitudes, have shown an association between type 1 diabetes mellitus (T1DM) and low serum 25OHD. We conducted a case–control study to determine whether, in a sub‐tropical environment with abundant sunlight (latitude 27.5°S), children with T1DM have lower serum vitamin D than children without diabetes. Fifty‐six children with T1DM (14 newly diagnosed) and 46 unrelated control children participated in the study. Serum 25OHD, 1,25‐dihydroxy vitamin D (1,25(OH)2D) and selected biochemical indices were measured. Vitamin D receptor (VDR) polymorphisms Taq1, Fok1, and Apa1 were genotyped. Fitzpatrick skin classification, self‐reported daily hours of outdoor exposure, and mean UV index over the 35 d prior to blood collection were recorded. Serum 25OHD was lower in children with T1DM (n = 56) than in controls (n = 46) [mean (95%CI) = 78.7 (71.8–85.6) nmol/L vs. 91.4 (83.5–98.7) nmol/L, p = 0.02]. T1DM children had lower self‐reported outdoor exposure and mean UV exposure, but no significant difference in distribution of VDR polymorphisms. 25OHD remained lower in children with T1DM after covariate adjustment. Children newly diagnosed with T1DM had lower 1,25(OH)2D [median (IQR) = 89 (68–122) pmol/L] than controls [121 (108–159) pmol/L, p = 0.03], or children with established diabetes [137 (113–153) pmol/L, p = 0.01]. Children with T1DM have lower 25OHD than controls, even in an environment of abundant sunlight. Whether low vitamin D is a risk factor or consequence of T1DM is unknown. 相似文献

Type 2 diabetes mellitus (DM) is being diagnosed more frequently in children and adolescents. Thailand has a low incidence of childhood DM. This study reviewed patients with DM in the Division of Pediatric Endocrinology, Faculty of Medicine, Siriraj Hospital compared to our previous study. The results demonstrate that type 2 DM in Thai children and adolescents has increased from 5% during 1986-1995 to 17.9% during 1996-1999. Mean age was 11.6 years. Mean BMI was 27.8 kg/m2. Fifty-six percent were diagnosed on routine examination. The period of increase in type 2 DM is associated with an increase of obesity prevalence from 5.8% in 1990 to 13.3% in 1996. This result emphasizes the importance of encouraging daily physical activity and healthy diet in our populations and also alerts our pediatricians and endocrinologists to the possibilities of type 2 DM in these age groups. 相似文献
