中、老年代谢综合征患者的临床特点分析

目的 比较中、老年代谢综合征(MS)患者的临床特点.方法 收集1996～2006年在解放军总医院门诊查体且符合中国人MS诊断标准(CDS)的947例中、老年患者的临床资料.其中老年人679例,中年人268例.分析中、老年患者MS各组分的差异,以及各组分的相关因素等.结果 947例患者中,男性582例(老年423例,中年159例),女性365例(老年256例,中年109例).老年男性患者的年龄大于老年女性(81.5±6.5 vs 74.5±8.8岁,P＜0.01),老年男性的体重指数(BMI)高于中年男性(27.14±2.51 vs 25.98±2.38,P＜0.01).老年患者的空腹、餐后血糖和收缩压均高于同性别的中年患者,而舒张压无显著差异.中年男性的甘油三酯高于老年男性.中年女性的高密度脂蛋白胆固醇高于男性.多元回归分析显示,男女患者空腹血糖均与餐后2h血糖有相关性(男性R2＝0.463,P＜0.05;女性R2＝0.613,P＜0.05).餐后2h血糖与年龄存在相关性(男性,R2＝0.522,P＜0.01;女性R2＝0.716,P＜0.05).收缩压与多种指标均有相关性,男性患者收缩压与年龄(R2＝0.396,P＜0.01)和舒张压(R2＝0.535,P＜0.05)均有相关性;女性患者的收缩压与BMI(R2＝0.557,P＜0.05)、舒张压(R2＝0.434,P＜0.05)、餐后2h血糖(R2＝0.434,P＜0.01)及空腹血糖(R2＝0.473,P＜0.05)均有相关性.Logistic回归分析示年龄(OR=2.1,95%CI:1.3～2.7)、空腹血糖(OR=1.7,95%CI:1.2～3.1)和收缩压(OR=1.4,95%CI:1.2～2.9)是预测代谢综合征组分含量的影响因素.结论 中老年代谢综合征患者的代谢指标有差异,年龄、空腹血糖和收缩压可作为代谢综合征的筛选指标.     

Microformats: Three Proposed Standards for Solving the Need for Standard Data Presentation

The continuous glucose monitor market is just starting to develop. Current trends in the availability of diabetes information tools highlight the need for standard data presentation for continuous glucose monitors. These trends and their implications are discussed. This article proposes a set of standards for blood glucose data presentation. If device manufacturers adopt these standards, they will ensure that their continuous glucose monitors meet both the short-term and the long-term needs of users. This should increase the demand for these monitors and enable future device developments that appeal to a wider range of users.

Incidence of Type 2 diabetes in England and its association with baseline impaired fasting glucose: the Ely study 1990-2000.

AIM: To determine the incidence of Type 2 diabetes and to examine the effect of different cut-points for impaired fasting glucose (IFG) on diabetes incidence. METHODS: Population-based longitudinal study (1990-2000) with clinical, anthropometric and biochemical measurements, including an oral glucose tolerance test (OGTT), in 1040 non-diabetic adults aged 40-69 years at baseline. Baseline glucose status was defined as normoglycaemia < 5.6, IFG-lower 5.6-6.0 and IFG-original 6.1-6.9 mmol/l. The all-IFG group included fasting glucose values of 5.6-6.9 mmol/l. RESULTS: The 10-year cumulative incidence of diabetes was 7.3 per 1000 person-years. Diabetes incidence was 2.4 [95% confidence interval (CI) 1.2, 4.8], 6.2 (4.0, 9.8) and 17.5 (12.5, 24.5) per 1000 person-years in those with normoglycaemia, IFG-lower and IFG-original, respectively. Compared with normoglycaemia, the age/sex-adjusted risk [hazard ratio (HR) and 95% CI] for incident diabetes was greatest in the IFG-original category (HR 6.9; 3.1, 15.2) and increased to a lesser degree in the IFG-lower (HR 2.5; 1.1, 5.7) and all-IFG categories (HR 4.1; 1.9, 8.7). When adjusted for confounding factors, the magnitude and direction of associations persisted, with HR 1.9, 4.4 and 2.9, for the categories IFG-lower, IFG-original and all-IFG, respectively. CONCLUSIONS: Diabetes incidence is more strongly related to IFG defined as fasting glucose between 6.1 and 6.9 mmol/l than to the lower category of 5.6-6.0 mmol/l, or entire range of 5.6-6.9 mmol/l. Future studies should examine the association of IFG with cardiovascular outcomes, but for diabetes risk our study supports the use of the IFG cut-point at 6.1 mmol/l.     

Uncooked rice of relatively low gelatinization degree resulted in lower metabolic glucose and insulin responses compared with cooked rice in female college students

Cooking processes that gelatinize granules or disrupt structure might increase the glucose and insulin responses because a disruption of the structure of starch by gelatinization increases its availability for digestion and absorption in the small intestine. We hypothesized that the uncooked form of rice, which has a relatively low degree of gelatinization even though in powder form, would result in lower metabolic glucose and insulin responses compared with cooked rice (CR). To assess the effects of the gelatinization of rice on metabolic response of glucose and insulin, we investigated the glucose and insulin responses to 3 rice meals of different gelatinization degree in female college students (n = 12): CR (76.9% gelatinized), uncooked rice powder (UP; 3.5% gelatinized), and uncooked freeze-dried rice powder (UFP; 5.4% gelatinized). Uncooked rice powders (UP and UFP) induced lower glucose and insulin responses compared with CR. The relatively low gelatinization degree of UPs resulted in low metabolic responses in terms of the glycemic index (CR: 72.4% vs UP: 49.7%, UFP: 59.8%) and insulin index (CR: 94.8% vs UP: 74.4%, UFP: 68.0%). In summary, UPs that were less gelatinized than CR induced low postprandial glucose and insulin responses.
