目的探讨糖化血红蛋白(HbAlc)对妊娠糖尿病(GDM)的筛查、诊断的价值。方法 932名足月单胎妊娠初产妇女在孕24~28周常规行75 g口服糖耐量试验(OGTT)和HbAlc检测,分别对照HbAlc各个切点的OGTT结果,观察不同HbAlc切点的诊断敏感性和特异性。结果 HbAlc在5.5%的敏感性为92.73%,特异性为51.43%;在6.0%的敏感性为72.73%,特异性为88.14%;在6.5%的敏感性为49.09%,特异性为99.77%。HbAlc超过5.5%后GDM的检出率即明显增加。如果考虑单个切点的诊断价值,HbAlc在6.0%为较适宜的切点。但在强调早期发现、干预孕期轻度高血糖的治疗新理念下,其作为筛查标准的敏感性不够。HbAlc≤5.5%的孕妇GDM风险低,HbAlc≥6.5%的孕妇极可能为GDM。HbAlc在5.5%~6.5%的孕妇为"HbAlc受损",其GDM发病风险明显增加,须加强孕期监测和管理。结论选择HbAlc在5.5%和6.5%两个切点,保证筛查的高敏感性和诊断的高特异性,可以更好地识别孕期高血糖。 相似文献

Objective
New guidelines recommend a target glycated hemoglobin (HbA1c) of 7.5% to 8.0% in elderly persons with type 2 diabetes mellitus (T2DM), but real-world data regarding outcomes associated with different HbA1c levels in the elderly are limited. This study assessed outcomes and their association with defined HbA1c thresholds and age ranges in insulin-treated, elderly, patients with T2DM in long-term care (LTC).Design
Retrospective analysis of medical charts and the Minimum Data Set (MDS) for the period September 2010 through September 2011.Setting
A total of 117 nursing homes in the United States.Participants
Eligible patients had resided in LTC for 3 months or more, had at least 1 full MDS assessment, 2 or more records of insulin dispensing with no pump use, and 1 or more HbA1c measurements.Measurements
Outcomes that were measured included hypoglycemia, ketoacidosis, infections, falls, hospitalization, and emergency room (ER) visits.Results
A total of 583 patients were included (mean age 78.9 years, mean chart observation length 55 days). In all groups, hypoglycemia was lowest in patients with an HbA1c level higher than 9.0%. In patients 75 years or older, infection rates were highest when HbA1c levels were higher than 9.0%. Falls increased by HbA1c level in patients aged 65 to 74 years, but decreased by HbA1c levels in patients 85 years or older. Ketoacidosis, hospitalization, and ER visits were low in all groups.Conclusion
These data suggest that better glycemic levels may not necessarily be associated with better clinical outcomes, and different age groups may exhibit different patterns, thereby supporting the call for individualized glycemic control among elderly patients. 相似文献15.
High-fiber diet interventions have been proven to be beneficial for gut microbiota and glycemic control in diabetes patients. However, the effect of a low level of fiber in habitual diets remains unclear. This study aims to examine the associations of habitual dietary fiber intake with gut microbiome profiles among Chinese diabetes patients and identify differential taxa that mediated associations of dietary fiber with HbA1c level. Two cross-sectional studies and one longitudinal study were designed based on two follow-up surveys in a randomized trial conducted during 2015–2017. The study included 356 and 310 participants in the first and second follow-ups, respectively, with 293 participants in common in both surveys. Dietary fiber intake was calculated based on a 3-day 24-h diet recall at each survey and was classified into a lower or a higher group according to the levels taken based on the two surveys using 7.2 g/day as a cut-off value. HbA1c was assayed to assess glycemic status using a cut-off point of 7.0% and 8.0%. Microbiome was profiled by 16S rRNA sequencing. A high habitual dietary fiber intake was associated with a decrease in α-diversity in both the cross-sectional and longitudinal analyses. At the first follow–up, phylum Firmicutes and Fusobacteria were negatively associated with a higher dietary fiber intake (p < 0.05, Q < 0.15); at the second follow-up, genus Adlercreutzia, Prevotella, Ruminococcus, and Desulfovibrio were less abundant in patients taking higher dietary fiber (p < 0.05, Q < 0.15); genus Desulfovibrio and Ruminococcaceae (Unknown), two identified differential taxa by HbA1c level, were negatively associated with dietary fiber intake in both the cross-sectional and longitudinal analyses, and mediated the dietary fiber-HbA1c associations among patients taking dietary fiber ≥ 7.2 g/day (mediation effect β [95%CI]: −0.019 [−0.043, −0.003], p = 0.018 and −0.019 [−0.046, −0.003], p = 0.016). Our results suggest that habitual dietary fiber intake has a beneficial effect on gut microbiota in Chinese diabetes patients. Further studies are needed to confirm our results. 相似文献

Background: Diet has been associated with poor glycemic control in diabetes. Few studies have examined this association in people with type 1 diabetes (T1D), who are at a higher risk for cardiovascular disease than people without diabetes. Methods: We report data from cross-sectional and longitudinal analyses from a coronary artery calcification in type 1 diabetes (CACTI) study (n = 1257; T1D: n = 568; non-diabetic controls: n = 689) collected between the years 2000 and 2002. Participants completed a validated food frequency questionnaire, a physical examination, and biochemical analyses. Dietary patterns based on variations in food group intake were created with principal components analysis. Linear regression was used to examine the associations of dietary patterns, macronutrients, and food groups with HbA1c in a model adjusted for relevant covariates and stratified by diabetes status. Results: Three dietary patterns were identified: “fruits, veggies, meats, cereal”, “baked desserts” and “convenience foods and alcohol” patterns. At baseline, a higher intake of the “baked dessert” pattern was significantly associated with higher HbA1c in T1D at baseline as well at year 6 of the study when adjusted for age, sex, BMI, total calories, and diabetes duration. No such associations were observed in the case of non-diabetic controls. Dietary saturated fats and animal fats were also positively associated with HbA1c in adults with T1D at baseline and/or at year 6. Conclusions: The habitual intake of a dietary pattern that is characterized by an increased intake of added sugar and saturated fats, such as in baked desserts, may increase risks of poor glycemic control in T1D. 相似文献
