目的探讨孕妇肥胖对婴儿体格发育和瘦素质量浓度的影响。
方法武汉大学人民医院儿科于2002年1月至2003年6月选择肥胖孕妇和正常体重孕妇各80例,比较她们的子代在出生后及满1岁时的体重、身高和血清瘦素质量浓度;瘦素检测使用双抗体夹心ELISA法。
结果符合检测数据统计条件的肥胖组为53例,正常组49例。(1)肥胖孕妇的瘦素质量浓度明显高于正常体重孕妇(P<0.01);(2)肥胖孕妇组子代出生体重和脐血瘦素质量浓度明显高于正常组(P<0.01);(3)肥胖孕妇组子代1岁时体重和血清瘦素质量浓度明显高于正常组子代(P<0.05)。
结论孕妇肥胖对婴儿的体重和瘦素质量浓度有明显的影响,此影响对子代以后的生长发育和瘦素质量浓度是否继续存在还需要进一步的研究。 相似文献

目的观察二甲双胍治疗对高胰岛素血症肥胖患儿血清脂源性激素脂联素、抵抗素、瘦素水平的影响。
方法2004 01—2005 02将武汉市儿童医院和同济医院54例高胰岛素血症肥胖患儿分为轻、中度肥胖组及重度肥胖组,均以二甲双胍治疗12周,测量治疗前后体重、空腹血糖、空腹胰岛素及脂源性激素脂联素、瘦素、抵抗素的变化。
结果治疗前轻、中度肥胖组和重度肥胖组高胰岛素血症患儿空腹血糖水平与健康对照组比较差异无显著性(P>0.05),血清胰岛素、瘦素、抵抗素及胰岛素抵抗指数(HOMA IR)均高于健康对照组(P<0.01),脂联素水平明显低于健康对照组(P<0.01)。二甲双胍治疗12周后与治疗前相比,血清胰岛素水平、胰岛素抵抗指数明显降低(P<0.01),轻、中度肥胖组及重度肥胖组血清瘦素水平分别由治疗前的(24.3±1.8)μg/L、(30.2±5.1)μg/L降低为治疗后的(19.6±6.3)μg/L、(24.7±5.3)μg/L,差异有统计学意义;抵抗素水平分别由治疗前的(16.5±6.0)μg/L、(22.3±5.2)μg/L升高为(22.0±5.1)μg/L、(30.6±11.7)μg/L,差异有统计学意义;轻、中度肥胖组和重度肥胖组血清脂联素水平治疗前分别为(8.4±3.2)mg/L、(6.5±1.2)mg/L,治疗后分别为(8.9±2.3)mg/L、(7.03±3.0)mg/L,治疗前后相比,P>0.05。体重指数(BMI)下降,但差异无显著性。
结论二甲双胍能显著改善肥胖患儿胰岛素抵抗。降低血清瘦素水平可能是其改善胰岛素抵抗机制之一,但在对脂源性激素脂联素、抵抗素水平的改善上,有其局限性。 相似文献

目的探讨血清脂联素水平与高胰岛素血症和(或)胰岛素抵抗的联系。
方法采用酶联免疫法测定2004-02—2004-12在天津医科大学总院就诊的34例肥胖儿童和31例正常对照的血清脂联素水平。分析血清脂联素与人体参数、体脂分布及糖代谢中各指标的相关关系。
结果(1)肥胖组脂联素水平低于对照组(P<0001)。(2)脂联素与性别、年龄无相关关系;与收缩压、舒张压呈负相关(相关系数分别为r=-0369,r=-0405,P<001);与BMI、腰臀比和SF呈负相关(相关系数分别为r=-0330,r=-0282和r=-0350,P<001);与空腹血糖、空腹胰岛素水平呈负相关(相关系数r=-0264和r=-0357,P<001);与HOMA R呈负相关(P<001),与HOMA β无相关关系。(3)多元回归分析表明,HOMA R是影响脂联素最为显著的因素,R2=0122;标准化偏回归系数-0369(P<001)。
结论肥胖症儿童血清脂联素水平较正常儿童降低。血清脂联素水平的变化,是影响空腹血糖、空腹胰岛素水平、HOMA R的重要因素。低脂联素血症可能参与胰岛素抵抗的发生。 相似文献

Serum leptin levels correlate with obesity parameters but not with hyperinsulinism in women with polycystic ovary syndrome 总被引:11,自引:0,他引:11
OBJECTIVE: To examine serum leptin concentrations in obese and lean patients with polycystic ovary syndrome (PCOS) to assess whether the changes in leptin levels are due to obesity or hormonal alterations. DESIGN: Controlled clinical study. SETTING: Academic research environment. PATIENT(S): Obese and lean women with PCOS. INTERVENTION(S): Blood samples were collected before and after food consumption. MAIN OUTCOME MEASURE(S): Serum leptin and insulin levels. RESULT(S): Serum leptin concentrations were significantly correlated with body mass index (r = 0.649) and also with HOMA (r = 0.535). However, after controlling for body mass index in a partial correlation analysis, no significant correlation was found between serum leptin levels and HOMA or hyperinsulinemia. While lean patients with PCOS had a significant correlation between leptin concentrations and obesity parameters, they did not show any significant correlation with insulin resistance parameters. CONCLUSION(S): Although leptin concentrations in women with PCOS correlate with insulin resistance/hyperinsulinemia, this is related only to obesity. 相似文献

Objectives To compare serum leptin levels in women with polycystic ovary syndrome (PCOS) and healthy subjects, and to evaluate the relationship between leptin concentration and insulin resistance.Methods Forty-five women with PCOS and 20 controls were included in the study. Serum levels of leptin, testosterone, immune-reactive insulin (IRI), sex hormone-binding globulin, dehydroepiandrosterone sulfate, cortisol, LH and FSH were measured. Free androgen index (FAI) and homeostasis model assessment of insulin resistance (HOMA-IR) were calculated. Body mass index (BMI) and waist-to-hip ratio (WHR) were assessed.Results Serum leptin levels in PCOS patients were higher than in the control group independently of BMI, WHR and waist circumference. In PCOS patients there was a strong positive correlation between leptin and IRI (r = 0.592, p < 0.01) on the one hand, and leptin and HOMA-IR, on the other (r = 0.637, p < 0.01). In PCOS patients with more pronounced insulin resistance (IR) the correlation between leptin levels and HOMA-IR is independent of BMI, WHR and waist circumference. We did not find any correlation between leptin and other hormonal indices in PCOS patients.Conclusions Our study confirms the existence of a significant positive correlation between serum leptin levels and clinical and hormonal indices of IR. The hyperleptinaemia is probably due to leptin resistance and may be characteristic of the syndrome. The lack of correlation with other hormonal parameters is probably due to the heterogeneity of the PCOS group. 相似文献

Neuropeptide Y, leptin, galanin and insulin in women with polycystic ovary syndrome. 总被引:8,自引:0,他引:8
B Baranowska M Radzikowska E Wasilewska-Dziubińska A Kapliński K Roguski A P?onowski 《Gynecological endocrinology》1999,13(5):344-351
It has been reported that polycystic ovary syndrome (PCOS) is very frequently associated with obesity, insulin resistance and hyperinsulinemia. However, metabolic disorders may lead to suppression of reproductive hormone secretion during undernutrition and in obesity. Some neuropeptides, such as neuropeptide Y (NPY) and galanin, modulate the control of appetite and play an important role in the mechanism of luteinizing hormone-releasing hormone (LHRH) secretion. NPY and galanin regulate appetite via both central and peripheral mechanisms. The interaction between central and peripheral signals for the control of food intake is due to leptin. Leptin can modulate the activity of NPY and other peptides in the hypothalamus that are known to affect eating behavior. In order to evaluate the relationship between NPY, galanin and leptin, 28 women with PCOS, 32 obese women (non-PCOS) and 19 lean healthy women (control group) were investigated. Obese women with PCOS were divided into two groups: PCOS (A) overweight (body mass index, BMI 26-30 kg/m2), and PCOS (B) obese (BMI 31-40 kg/m2). Plasma NPY, galanin and leptin concentrations were measured by radioimmunoassay. Plasma leptin levels in obese women with PCOS (groups A and B) were significantly higher than those in the control group (p < 0.05, p < 0.05, respectively). A significant positive correlation between plasma leptin and BMI in women with PCOS was found (r = 0.427, p < 0.01). A positive correlation was demonstrated between leptin and testosterone in PCOS (r = 0.461, p < 0.01). Plasma galanin concentrations in PCOS were higher than in the control group but the differences were not significant. Plasma NPY levels were significantly elevated in both non-obese (normal) and obese women with PCOS (group A) (p < 0.01, p < 0.005, respectively). However, in obese non-PCOS women plasma NPY levels gradually increased with increase in BMI. No significant correlations were found between galanin, NPY and percentage change in response of LH to LHRH, as well as between NPY and insulin, and galanin and testosterone. Plasma insulin concentrations in women with PCOS (group B) were significantly higher than in the control group (p < 0.001). Increased plasma NPY levels are found in both obese and non-obese women with PCOS. The increase in NPY is independent of the increase in BMI. In obese women with PCOS, plasma leptin is increased compared with control lean women. Serum insulin concentration is increased in obese women with PCOS. A positive correlation exists between leptin and BMI as well as between leptin and testosterone in women with PCOS. These results may suggest that the feedback system in the interaction between leptin and NPY is disturbed in PCOS. 相似文献

性早熟女童糖脂代谢与脂联素的关系 总被引:7,自引:1,他引:7
目的分析中枢性性早熟(CPP)女童糖脂代谢的特点及脂联素在性早熟女童糖、脂代谢中的作用。
方法浙江大学医学院附属儿童医院于2004年6~10月收治50例CPP女童,测量空腹血糖、胰岛素、甘油三酯、胆固醇、脂联素,并做葡萄糖耐量试验和胰岛素释放试验,采用总体胰岛素敏感指数(WBISI)、胰岛素抵抗指数(HOMA IR)这2个指标来评估胰岛素敏感性和胰岛β细胞功能。并与年龄匹配的正常对照组进行比较。
结果(1)CPP女童空腹胰岛素、HOMA IR明显高于正常对照组(P<0.01)。(2)CPP女童A1组胆固醇较正常对照组明显升高(P<0.05)。(3)CPP女童体重指数(BMI)值均较正常对照组明显升高(P<0.05)。其中超重16%(8/50),肥胖8%(4/50)。(4)CPP女童脂联素均较正常对照组明显下降(P<0.01)。(5)CPP女童BMI值与WBISI显著负相关(r=-0.31,P<0.05),与HOMA IR显著正相关(r=0.30,P<0.05),与脂联素显著负相关(r=-0.43,P<0.01)。CPP女童脂联素与WBISI显著正相关(r=0.29,P<0.05),多元回归分析显示CPP女童脂联素与WBISI、HOMA IR无显著相关性。(6)排除12例超重加肥胖CPP女童后再分析显示A1、A2组女童空腹胰岛素、HOMA IR仍明显高于正常对照组(P<0.01),而脂联素水平3组差异无显著性。
结论(1)CPP女童存在不同程度的胰岛素抵抗,尤见于BMI值明显升高的性早熟女童。(2)肥胖或超重的性早熟女童胰岛素抵抗可能与脂联素水平下降有关。 相似文献

Background and purposeAppetite disturbance is a common problem in obesity and depression. The beneficial effects of polyphenols in promoting satiety have been shown. This study aimed to investigate the effects of sumac supplementation along with calorie restricted diet (CRD) on appetite in overweight and obese women with depression.Materials and methodsIn this trial, 60 overweight and obese women with depression were randomly assigned to receive a CRD plus 3 g/day of either sumac or placebo for 12 weeks. The appetite score, serum levels of leptin, neuropeptide Y (NPY), insulin, fasting blood sugar (FBS), homeostasis model assessment of insulin resistance (HOMA-IR), and quantitative insulin sensitivity check index (QUICKI) were assessed at baseline and at the end of the study.ResultsSumac supplementation significantly reduced the appetite score (p = 0.02), serum levels of leptin (p = 0.03), NPY (p = 0.01), insulin (p = 0.03), FBS (p = 0.03), and HOMA-IR (p = 0.02) compared to the placebo group. QUICKI increased significantly in the sumac group compared to the placebo group (p = 0.009).ConclusionSumac along with a CRD may have some beneficial effects on appetite through possible modulatory effects on leptin resistance, insulin sensitivity, and NPY levels in overweight and obese women with depression. 相似文献

The objective of this study is to measure serum chemerin levels in women with polycystic ovary syndrome (PCOS) and assess their relationship with clinical, metabolic, and hormonal parameters. One hundred eighteen PCOS women and 114 healthy women were recruited in this study. Their blood pressure, body mass index (BMI), waist circumference and waist-to-hip ratio (WHR), fasting insulin (FIN), fasting plasma glucose (FPG), blood serum sex hormone, and blood lipid were measured. Serum chemerin, leptin, and adiponectin were measured by ELISA. Serum chemerin was significantly higher in the obese PCOS group (47.62?±?11.27?ng/mL) compared with non-obese PCOS (37.10?±?9.55?ng/mL) and the obese (33.71?±?6.17?ng/mL) and non-obese (25.78?±?6.93?ng/mL) control groups (p?0.05). Serum chemerin was positively related to BMI, waist circumference, WHR, testosterone (T), FPG, FIN, homeostasis model assessment of insulin resistance (HOMA-IR), total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL-C), LDL-C/high-density lipoprotein(HDL-C), TC/HDL-C and serum leptin, while negatively related to glucose-to-insulin ratio (G/I), HDL-C, and adiponectin levels. Multiple linear regression analysis revealed HOMA-IR, leptin, and TC were the significant influencing factors of chemerin levels (p?0.05). Increased serum chemerin in PCOS woman with or without obesity suggested that chemerin may be involved in the development of the pathogenesis of PCOS. 相似文献
