高尿酸血症的患病情况及相关因素分析

目的调查我国9省市35～70岁人群高尿酸血症患病率及其相关因素。方法采用整群抽样的方法,调查了15706例居民高尿酸血症患病情况并应用Logistic回归模型分析高尿酸血症的影响因素。结果高尿酸血症的患病率为12.08%(标化后11.57%),其中男性为14.59%(标化后14.84%),女性为10.21%(标化后9.21%);高尿酸血症患病率在女性人群中是随着年龄增长而升高(趋势卡方检验P<0.05),而在男性人群未见明显趋势(趋势卡方检验P>0.05)。高尿酸血症伴发疾病中以高脂血症最为常见(80.40%),其次为超重和肥胖(74.61%)、高血压(58.32%)、腹型肥胖(45.47%)、糖尿病(11.80%);多因素Logistic回归模型显示:年龄(OR=1.01,95%CI:1.01～1.02)、男性(OR=1.36,95%CI:1.21～1.53)、高甘油三酯血症(OR=4.28,95%CI:3.84～4.76)、高胆固醇血症(OR=1.19,95%CI:1.06～1.33)、高血压(OR=1.17,95%CI:1.05～1.30)、肥胖(OR=1.69,95%CI:1.52～1.88)、饮酒(OR=1.36,95%CI:1.19～1.56)与高尿酸血症显著相关。结论高甘油三酯血症、高胆固醇血症、年龄、男性、高血压、肥胖可能为高尿酸血症的危险因素;随着肥胖和代谢综合征发生率的增加以及高尿酸血症与心血病的密切关系,积极控制高尿酸血症对心血管疾病的控制有着十分重要的意义。     

不宁腿综合征患者合并焦虑的电生理标记物研究

目的探讨不宁腿综合征(RLS)患者合并焦虑的电生理标记物。方法选择原发性RLS患者58例,进行RLS问卷调查和多导睡眠图(PSG)检查,采用贝克焦虑量表(BAI)和汉密尔顿焦虑量表(HAMA)评估焦虑情绪。采用Spearman或pearson相关分析焦虑程度和PSG电生理指标的相关程度。结果在睡眠结构中,HAMA和BAI总分与N2占总睡眠时间的比例呈负相关(r分别=-0.26、-0.26,P均<0.05),HAMA和BAI总分与N3占总睡眠时间的比例呈正相关(r分别=0.31、0.36,P均<0.05)。在睡眠期肢体运动情况监测中,HAMA和BAI评分均与睡眠周期性腿动次数(PLMS)、PLMS指数、睡眠N2期腿动次数、睡眠N1期腿动指数、睡眠N2期腿动指数呈正相关(r分别=0.30、0.27、0.31、0.38、0.40;0.31、0.29、0.35、0.38、0.37,P均<0.05)。结论RLS患者合并焦虑程度与睡眠结构紊乱和睡眠中腿动事件可能相关,提示这些指标可能是RLS相关焦虑的电生理指标。     

Prevalence of restless legs syndrome in migraine patients with and without aura: a cross-sectional,case-controlled study

Background

Although the comorbidity of migraine and restless legs syndrome (RLS) has been well-documented, the association between RLS and migraine frequency has yet to be elucidated. The present study aims to evaluate the prevalence of RLS among individuals who experience low-frequency, high-frequency, or chronic migraine presenting with and without aura.

Methods

We conducted a cross-sectional, case-controlled study involving 505 participants receiving outpatient headache treatment. Standardized questionnaires were administered to collect information on experiences of migraine, RLS, sleep quality, anxiety, depression, and demographics. Participants were categorized into low-frequency (1–8/month), high-frequency (9–14/month), and chronic (≥15/month) headache groups. RLS was diagnosed according to the criteria outlined by the International RLS Study Group (IRLSSG). The Pittsburgh Sleep Quality Index (PSQI) and Hospital Anxiety and Depression Scale (HADS) were used to assess sleep quality and identify symptoms of anxiety and depression. Associations between migraine frequency and RLS prevalence were investigated using multivariate linear and logistic regression.

Results

Univariate analysis revealed an effect of migraine frequency on RLS prevalence (p?=?0.026), though this effect did not persist following adjustment for baseline characteristics (p?=?0.256). The trend was robust in patients whose migraines presented with auras (p _univariate?=?0.002; p _multivariate?=?0.043) but not in those without auras (p _univariate and p _multivariate?>?0.05). Higher anxiety [odds ratio (OR)?=?1.18, p?=?0.019] and sleep disturbance (OR?=?1.17, p?=?0.023) scores were associated with higher RLS prevalence.

Conclusions

Higher migraine frequency correlates with a higher prevalence of RLS, particularly among patients with auras.

     

Prevalence and determinants of type 2 diabetes among Filipino-Americans in the Houston, Texas metropolitan statistical area.

OBJECTIVE: The few available studies suggest that Filipino-Americans have an increased risk for developing type 2 diabetes. The purpose of this study was to determine the prevalence of previously diagnosed type 2 diabetes and its major risk factors among Filipino-Americans. RESEARCH DESIGN AND METHODS: A cross-sectional survey was conducted in the Houston, Texas, metropolitan statistical area between September 1998 and March 2000. The convenience sample included 831 Filipino-American participants aged 20-74 years. The major risk factors assessed were age, sex, family history of diabetes, socioeconomic status, obesity (BMI >30), physical inactivity, acculturation, region of birth and, in women, history of gestational diabetes and delivery of a baby weighing > 9 lb. RESULTS: Overall prevalence was estimated to be 16.1% (95% CI 13.5-18.7). Multivariate logistic regression analyses identified independent risk factors: increasing age from ages 35-44 years (odds ratio [OR] 5.6, 95% CI 1.5-20.5) to 65-74 years (34.2, 7.2-163.0); male sex (1.8, 1.1-32.1); family history of diabetes (4.7, 2.6-8.5); obesity (3.6, 1.4-9.0); region of birth, Mindanao (3.2, 1.3-7.7); and, among women, gestational diabetes (21.7, 6.7-69.7) and low income (5.3, 1.4-20.2). CONCLUSIONS: The study observed a high prevalence of type 2 diabetes and supports earlier studies suggesting that Filipinos are at higher risk for type 2 diabetes than the U.S. non-Hispanic white population.     

Grip strength and the metabolic syndrome: findings from the Hertfordshire Cohort Study

INTRODUCTION: Sarcopenia, the loss of muscle mass and strength with age, is significantly associated with type 2 diabetes in older people. AIM: To determine whether there is a relationship between grip strength and features of the metabolic syndrome. DESIGN: Cross-sectional study. METHODS: Data were collected on grip strength, fasting glucose, triglycerides and HDL cholesterol, blood pressure, waist circumference and 2 h glucose after an oral glucose tolerance test, in a population-based sample of 2677 men and women aged 59-73 years. RESULTS: In men and women combined, a standard deviation (SD) decrease in grip strength was significantly associated with higher: fasting triglycerides (0.05 SD unit increase, 95%CI 0.02-0.09, p = 0.006); blood pressure (OR 1.13, 95%CI 1.04-1.24, p = 0.004); waist circumference (0.08 SD unit increase, 95%CI 0.06-0.10, p < 0.001); 2 h glucose (0.07 SD unit increase, 95%CI 0.03-0.11, p = 0.001) and HOMA resistance (0.05 SD unit increase, 95%CI 0.01-0.09, p = 0.008), after adjustment for gender, weight, age, walking speed, social class, smoking habit and alcohol intake. Lower grip strength was also significantly associated with increased odds of having the metabolic syndrome according to both the ATPIII (OR 1.18, 95%CI 1.07-1.30, p < 0.001) and IDF definitions (OR 1.11, 95%CI 1.01-1.22, p = 0.03). DISCUSSION: Our findings suggest that impaired grip strength is associated with the individual features, as well as with the overall summary definitions, of the metabolic syndrome. The potential for grip strength to be used in the clinical setting needs to be explored.     

Side effects of opioids during short-term administration: effect of age,gender, and race

OBJECTIVE: Little is known about risk factors that increase the risk of development of opioid side effects. Our objective was to evaluate the effect of the type of opioid, age, gender, and race on the incidence of side effects from short-term opioid use. METHODS: A secondary analysis of a retrospective cohort study in 35 community-based and tertiary hospitals was done. There were 8855 black or white subjects aged 16 years and older. Patients received meperidine (INN, pethidine), morphine, or fentanyl as part of their treatment. Measurements were made to assess the presence of nausea and vomiting and respiratory depression. RESULTS: Of the patients, 26% had nausea and vomiting and 1.5% had respiratory depression after opioid administration. After adjustment for opioid dose, route of administration, age, gender, and race, meperidine produced less nausea and vomiting (odds ratio [OR] = 0.7; 95% confidence interval [CI], 0.5-0.8) and less respiratory depression (OR = 0.6; 95% CI, 0.2-0.9) than morphine. The risk of respiratory depression increased with age. Compared with patients aged between 16 and 45 years, those aged between 61 and 70 years had 2.8 times the risk of development of respiratory depression (95% CI, 1.2-6.6); those aged between 71 and 80 years had 5.4 times the risk (95% CI, 2.4-11.8); and those aged older than 80 years had 8.7 times the risk (95% CI, 3.8-20.0). Men had less nausea and vomiting than women (OR = 0.5; 95% CI, 0.4-0.6). White subjects had more nausea and vomiting than black subjects (OR = 1.4; 95% CI, 1.1-1.7). CONCLUSIONS: Meperidine produced fewer side effects than morphine during short-term use. The risk of respiratory depression increases substantially after 60 years of age. Women have nausea and vomiting more often than men. The effect of race deserves further investigation.     

Characteristics and behaviours associated with difficulty in performing activities of daily living among older New Zealand women

Purpose: The objective of this cross-sectional study was to determine the prevalence of self-reported difficulty in perfoming activities of daily living (ADLs) and the associated characteristics and behaviours among older women in Auckland, New Zealand. Methods: A sample of 569 community dwelling women aged 65 years and older were studied. Logistic regression was used to calculate odds ratios and 95% confidence intervals for the association of participant characteristics and behaviours with reported difficulty in performing 1 of five basic ADLs. Results: An age adjusted prevalence of 4.6% was found for reported ADL difficulty. Age 85 years (odds ratio [OR] 5.9; 95% confidence interval [CI] 1.1-30.2), history of stroke (OR 9.8; 95% CI 4.1-23.3), history of 1 fall in the past year (OR 3.4; 95% CI 1.6-7.4), low body mass index (OR 2.8; 95% CI 1.2-6.4), and low grip strength (OR 2.6; 95% CI 1.2-5.5) were significantly and independently associated with ADL difficulty. Among women with ADL difficulty, the prevalence of adaptive equipment use was high (>90%). Conclusions: Several characteristics, medical conditions, and behaviours, some of which may be preventable, are associated with physical disability in older New Zealand women. Studies like this are an important step toward the development of interventions to reduce or delay disability and improve health and quality of life.     

Can we apply the National Cholesterol Education Program Adult Treatment Panel definition of the metabolic syndrome to Asians?

OBJECTIVE: Limited information is available about the metabolic syndrome in Asians. Furthermore, the definition of central obesity using waist circumference may not be appropriate for Asians. The objectives of this study were to determine the optimal waist circumference for diagnosing central obesity in Asians and to estimate the prevalence of the metabolic syndrome in an Asian population. RESEARCH DESIGN AND METHODS: We used data from the 1998 Singapore National Health Survey, a cross-sectional survey involving 4,723 men and women of Chinese, Malay, and Asian-Indian ethnicity aged 18-69 years. Receiver operating characteristic analysis suggested that waist circumference >80 cm in women and >90 cm in men was a more appropriate definition of central obesity in this population. The prevalence of the metabolic syndrome was then determined using the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria with and without the modified waist circumference criteria. RESULTS: In Asians, decreasing waist circumference increased the crude prevalence of the metabolic syndrome from 12.2 to 17.9%. Using the modified Asian criteria, the prevalence of the metabolic syndrome increased from 2.9% in those aged 18-30 years to 31.0% in those aged 60-69 years. It was more common in men (prevalence 20.9% in men versus 15.5% in women; P < 0.001) and Asian Indians (prevalence 28.8% in Asian-Indians, 24.2% in Malays, and 14.8% in Chinese; P < 0.001). CONCLUSIONS: NCEP ATP III criteria, applied to an Asian population, will underestimate the population at risk. With a lower waist circumference cutoff, the prevalence of the metabolic syndrome is comparable to that in Western populations. Ethnic differences are likely to exist between populations across Asia.     

Regional trends in obesity and overweight among Austrian adults between 1973 and 2007

This paper examines regional changes in the prevalence of overweight (BMI ≥ 25 kg/m2) and obesity (BMI ≥ 30 kg/m2) among Austrian adults (aged ≥ 20 years) during a 35-year period, taking into account the social inequality with regard to obesity. Self-reported data from five cross-sectional nationally representative surveys (n = 178,818) conducted between 1973 and 2007 were analysed. The prevalence of overweight was higher in men than women (2007: 46.3 vs. 31.2 %;p < 0.001) and similar in all Austrian regions. There was a clear east-west gradient for obesity among both sexes, with the highest rates in Eastern Austria (in 2007, women: 18.1 %, men: 16.1 %;p < 0.001) and the lowest in Western Austria (in 2007, women: 12.6 %, men: 11.7 %;p < 0.001). Logistic regression analyses have shown a general decrease of overweight per year among women (OR = 0.991, 95 % CI 0.990-0.993) and men (OR = 0.999, 95 % CI 0.998-1.000), while the obesity prevalence has risen during the study period in every region (women: OR = 1.003, 95 % CI 1.001-1.005; men: OR = 1.011, 95 % CI 1.009-1.013), with the highest increase among women in Central Austria and men in Western Austria. Social inequalities for obesity showed a tendency to increase in the Western and Eastern region. Our results showed a significant regional difference for obesity prevalence during the entire study period. Obesity is a frequent health problem among Austrian adults residing in the Eastern region.

METHODS: A sample of 569 community dwelling women aged 65 years and older were studied. Logistic regression was used to calculate odds ratios and 95% confidence intervals for the association of participant characteristics and behaviours with reported difficulty in performing > or = 1 of five basic ADLs. RESULTS: An age adjusted prevalence of 4.6% was found for reported ADL difficulty. Age > or = 85 years (odds ratio [OR] 5.9; 95% confidence interval [CI] 1.1-30.2), history of stroke (OR 9.8; 95% CI 4.1-23.3), history of > or = 1 fall in the past year (OR 3.4; 95% CI 1.6-7.4), low body mass index (OR 2.8; 95% CI 1.2-6.4), and low grip strength (OR 2.6; 95% CI 1.2-5.5) were significantly and independently associated with ADL difficulty. Among women with ADL difficulty, the prevalence of adaptive equipment use was high (> 90%). CONCLUSIONS: Several characteristics, medical conditions, and behaviours, some of which may be preventable, are associated with physical disability in older New Zealand women. Studies like this are an important step toward the development of interventions to reduce or delay disability and improve health and quality of life.     

Are Sleep Difficulties Associated With Migraine Attributable to Anxiety and Depression?

Objective.— To examine whether sleep complaints reported by migraineurs can be attributed to comorbid anxiety and/or depression. Background.— A consistent association between migraine and sleep complaints has been reported in community and clinical studies. However, anxiety and depression are often comorbid with migraine. Thus, it may be possible that the increased prevalence of sleep problems in migraineurs is attributable to comorbid anxiety and depression. To our knowledge, no previous studies have demonstrated that the associations are not solely attributed to comorbid anxiety and depression. Design and Methods.— Controlled family study of anxiety disorders and substance use disorders in a community in New Haven County, CT. The sample included 221 probands (41 migraineurs) and their 261 directly interviewed first‐degree relatives (39 migrainuers), including parents, siblings, and offspring over age 18. A lifetime history of migraine was obtained using the Diagnostic Interview for Headache Syndromes. A lifetime history of psychiatric disorders was obtained using the semi‐structured Schedule for Affective Disorders and Schizophrenia which was modified to incorporate Diagnostic and Statistical Manual diagnostic criteria. Several sleep items on current and lifetime sleep complaints were included as a subset of the interview. Results.— There was a significant association between migraine and the number of sleep problems as well as several specific sleep symptoms among probands and their adult relatives. Adults with migraine reported having significantly more lifetime sleep problems (OR [CI] = 2.3 [1.1‐4.6]), and more current sleep difficulties, specifically, inadequate sleep (2.5 [1.2‐5.0]), difficulty falling asleep (3.0 [1.5‐6.3]), and persistent nightmares of childhood onset (4.3 [1.8‐9.9]) than those without migraine. The associations between sleep problems and migraine persisted after controlling for both lifetime and current anxiety and mood disorders. Conclusions.— The association between sleep problems and migraine that is not solely explained by comorbid anxiety disorders or depression suggests that sleep problems should be evaluated among people with migraine.

Does diabetes mellitus explain the higher hospital mortality of women with acute myocardial infarction? Results from the Berlin Myocardial Infarction Registry.

BACKGROUND: Women with acute myocardial infarction (AMI) exhibit greater hospital mortality than do men. In general, diabetes mellitus is one of the major factors influencing the outcome of patients with AMI. The aim of this study was to analyze the interaction between diabetes and gender, specifically with regard to the higher hospital mortality of female AMI patients aged < or = 75 years. METHODS: We prospectively collected data from 3,715 patients aged < or = 75 (2,794 men, 921 women) with acute myocardial infarction who were treated in 25 hospitals in Berlin, Germany, from 1999 to 2002. In a multivariate analysis, we specifically studied the interaction between the factors diabetes mellitus and gender in their effects on hospital mortality. RESULTS: After adjustment in multivariate analysis, the interaction between gender and diabetes was statistically significant, and the estimated odds ratios were as follows: female diabetic patients compared with male diabetic patients, odds ratio (OR) = 2.28 (95% confidence interval [CI] 1.42-3.68); female diabetic patients compared with male nondiabetic patients, OR = 2.90 (95% CI 1.90-4.42); and female diabetic patients compared with female nondiabetic patients, OR = 2.92 (95% CI 1.75-4.87). There was no statistically significant difference between the risk of dying for female nondiabetic patients or for male diabetic patients when compared with male nondiabetic patients. CONCLUSIONS: In AMI patients aged < or = 75 years, female gender alone is not an independent predictor of hospital mortality. Detailed, multivariate analysis reveals that specifically diabetic women demonstrate higher hospital mortality than do men. Special attention should be provided to these female diabetic patients.

Psychiatric symptoms in children and adolescents with cyclic vomiting syndrome and their parents

OBJECTIVE: To conduct a pilot study to evaluate the prevalence of psychiatric symptoms in children and adolescents with cyclic vomiting syndrome and to assess family history of psychiatric disorder. BACKGROUND: Little is known about psychiatric comorbidity in youth with cyclic vomiting syndrome, a periodic syndrome. METHODS: Eighty-five parents, of children aged 3-18 years with cyclic vomiting syndrome confirmed in a multidisciplinary clinic, completed the age-appropriate Children's Symptom Inventory, a questionnaire that screens for psychiatric symptoms in pediatric patients. Twenty-one adolescents aged 13-18 years completed the Youth's Report, a self-report form of this questionnaire. Sixty-two parents completed a family psychiatric history checklist. RESULTS: These children and their parents evidenced a high prevalence of anxiety and mood symptoms compared to norms of the Children's Symptom Inventory and population norms for internalizing psychiatric disorders. On the age-appropriate Children's Symptom Inventory, 47% of subjects (40/85) met diagnostic cut-off for an anxiety disorder, and 14% (12/85) for an affective disorder. Discrepancies were found in parent and adolescent reports for symptoms of panic disorder (chi-square = 4.83, df = 1, P = .028), posttraumatic stress disorder (chi-square = 6.87, df = 1, P = .009), and somatization disorder (chi-square = 6.41, df = 1, P = .01), with parents reporting significantly more symptoms than the adolescents. Internalizing disorders were also prevalent in the parents with 59% (36/62) endorsing either an anxiety and/or an affective disorder. Mothers reported a significantly higher prevalence of anxiety disorders (35%) than did fathers (13%) (chi-square = 8.43, df = 1, P < .004). CONCLUSION: Children and adolescents with cyclic vomiting syndrome appear to be at increased risk for internalizing psychiatric disorders, especially anxiety disorders. Further research using standardized psychiatric interviews and a control group are indicated to further assess psychiatric disorders in children and adolescents with cyclic vomiting syndrome.     

Gender differences in metabolic syndrome risk factors among patients with serious mental illness

The prevalence of metabolic syndrome and its components continue to increase among patients with serious mental illness. This cross‐sectional study investigated whether metabolic syndrome prevalence and risk factors differ between male and female patients with serious mental illness. In total, 260 eligible patients were recruited from two hospitals. The data on demographic characteristics, lifestyle behaviour factors, biochemistry, and anthropometry were collected. Analyses were performed using multivariate logistic regression. Metabolic syndrome prevalence was 40.8% (35.1% in men and 46.8% in women). Among patients aged 40–49 years, metabolic syndrome prevalence was higher in men; however, the trend was reversed among patients aged 50 years or older. Notably, gender‐specific metabolic syndrome risk factors were observed. In men, they included low education level, high body mass index (BMI), prolonged illness, comorbid physical illness, and diagnosis of bipolar disorder, whereas they included being married, old age, and high BMI in women. Our findings suggest that mental health professionals should consider the gender‐ and age‐based metabolic syndrome prevalence trend in patients with serious mental illness when designing interventions for the study population to minimize metabolic syndrome prevalence.     

Association between short sleep duration and high incidence of metabolic syndrome in midlife women

Chronic sleep deprivation is increasingly common in industrialized societies. Short sleep duration has been associated with a number of negative health outcomes. The objectives of this study were to investigate the association between self-reported sleep duration and the presence of metabolic syndrome (combination of central obesity, triglyceride, high density lipoprotein, blood pressure, fasting plasma glucose) in adults during midlife. The Korean Genomic Rural Cohort (KGRC) is a cohort study of aged 40 to 70 years in rural Korea. This study focuses on the prevalence, incidence, and risk factors for chronic degenerative disorders, such as hypertension, diabetes, osteoporosis, respiratory diseases, and metabolic syndrome. The baseline sample of participants in the KGRC study was recruited in 2005-2006 (phase 1). Respondents were followed until 2008-2009 (phase 2). The final sample included 1,107 subjects: 386 males (34.9%) and 721 females (65.1%). The incidence rate of metabolic syndrome in our sample was 18.4% (21.2% for males and 16.9% for females). Subjects sleeping < 6 hours a day (HR: 1.798; 95% CI: 1.06-3.05) were significantly more likely to experience metabolic syndrome than participants sleeping 6 to 7.9 hours a day after controlling for potential covariates (age, body mass index, menopause, smoking, alcohol and physical activity). Shorter sleep duration was associated with the high incidence of metabolic syndrome among females only. In conclusion, shorter sleep duration may be a significant risk factor for the development of metabolic syndrome in women.     

Migraine with and without aura: association with depression and anxiety disorder in a population-based study. The HUNT Study

Some data indicate that migraine with aura (MA) is more strongly associated with anxiety disorder and depression than migraine without aura (MoA), but the evidence is not conclusive. In the Nord-Tr?ndelag Health study 1995-1997, a total of 49 205 (75% of the participants) subjects gave valid answers to both HADS (Hospital Anxiety and Depression Scale) and a validated headache questionnaire. Associations between anxiety disorder/depression and MA/MoA were evaluated by multiple logistic regression analysis. Depression (DEP) [odds ratio (OR) 1.7; 95% confidence interval (CI) 1.2, 2.6] and depression with comorbid anxiety disorder (COM) (OR 1.6; 95% CI 1.2, 2.1) were more likely in women having MA than in those with MoA. No stronger association was found for pure anxiety disorder (ANX) in MA vs. MoA (OR 0.9; 95% CI 0.7, 1.5). Among men, we found no difference in prevalence of depression and anxiety disorders between MA and MoA. This is a new finding that might have relevance for both research and clinical treatment.     

Metabolic syndrome among HIV-infected patients: prevalence, characteristics, and related factors

OBJECTIVE: To assess the prevalence in HIV-infected patients of the metabolic syndrome as defined by the National Cholesterol Education Program, i.e., three or more of the following components: abdominal obesity, hypertriglyceridemia, low HDL cholesterol, high blood pressure, and high fasting glucose. RESEARCH DESIGN AND METHODS: In this cross-sectional study, 710 HIV-infected patients managed at the outpatient clinic of a tertiary hospital during 2003 completed the study protocol consisting of a medical examination and laboratory analysis after a 12-h overnight fast. RESULTS: Metabolic syndrome prevalence was 17% and increased from 5.1% among HIV-infected patients under age 30 years to 27.0% for those aged 50-59 years. Age (per 10-year increment) (odds ratio [OR] 1.41 [95% CI 1.12-1.77]), BMI (1.27 [1.19-1.36]), past and present protease inhibitor exposure (2.96 [1.03-3.55] and 4.18 [1.4-12.5], respectively) were independently associated with the metabolic syndrome on logistic regression analysis. Furthermore, only stavudine (d4T) (1.74 [1.01-2.98]) and lopinavir/ritonavir (2.46 [1.28-4.71]) were associated with the metabolic syndrome after adjustment for age and BMI. CONCLUSIONS: The prevalence of metabolic syndrome among these HIV-infected patients is similar to that previously reported in uninfected individuals. Of specific concern is the association of protease inhibitor exposure with the metabolic syndrome and, more specifically, with exposure to stavudine and lopinavir/ritonavir when individual antiretroviral drugs were analyzed.     

Prevalence of the metabolic syndrome defined by the International Diabetes Federation among adults in the U.S

OBJECTIVE: The International Diabetes Federation (IDF) has proposed a new definition of the metabolic syndrome that emphasizes central adiposity as determined by ethnic group-specific thresholds of waist circumference. The objective of this study was to estimate the prevalence of this syndrome using the IDF definition among U.S. adults and to compare it with the prevalence estimated using the definition of the National Cholesterol Education Program (NCEP). RESEARCH DESIGN AND METHODS: A total of 3,601 men and women aged > or =20 years from the National Health and Nutrition Examination Survey 1999-2002 were included in the analyses. RESULTS: Based on the NCEP definition, the unadjusted prevalence of the metabolic syndrome was 34.5 +/- 0.9% (percent +/- SE) among all participants, 33.7 +/- 1.6% among men, and 35.4 +/- 1.2% among women. Based on the IDF definition, the unadjusted prevalence of the metabolic syndrome was 39.0 +/- 1.1% among all participants, 39.9 +/- 1.7% among men, and 38.1 +/- 1.2% among women. The IDF definition led to higher estimates of prevalence in all of the demographic groups, especially among Mexican-American men. The two definitions similarly classified approximately 93% of the participants as having or not having the metabolic syndrome. CONCLUSIONS: In the U.S., the use of the IDF definition of the metabolic syndrome leads to a higher prevalence estimate of the metabolic syndrome than the estimate based on the NCEP definition.
