Context: Nonalcoholic fatty liver disease (NAFLD) has been considered as a hepatic manifestation of the metabolic syndrome and is associated with various metabolic abnormalities, which may link to an increased risk of osteoporotic fracture. However, epidemiological studies investigating the association between NAFLD and osteoporotic fracture were not available. Objective: The objective of the study was to determine whether NAFLD associates with osteoporotic fracture. Design, Setting, and Participants: This was a cross-sectional study of 7797 Chinese adults aged 40 yr or older in the Jiading District, Shanghai, China. Main Outcome Measures: A questionnaire, anthropometric measurements, laboratory tests, and a hepatic ultrasonic examination were conducted. NAFLD was diagnosed by hepatic ultrasound after the exclusion of alcohol abuse and other liver diseases. A history of fractures was collected with an interviewer-assisted questionnaire. Osteoporotic fractures were defined as fractures that occurred due to low-trauma in 2 yr prior to the study. Results: Among men, the prevalence of osteoporotic fractures was significantly higher in those with NAFLD (3.6 vs. 1.7%, P = 0.003); however, no difference was found in women (3.4 vs. 2.6%, P = 0.14). The presence of NAFLD was significantly associated with increased odds of osteoporotic fracture among men (odds ratio 2.53; 95% confidence interval 1.26–5.07; P = 0.009) after controlling for potential confounders. The significant associations were not detected in women. Conclusions: The presence of NAFLD was significantly associated with a recent history of osteoporotic fracture in middle-aged and elderly Chinese men.

【期刊论文】Urinary Bisphenol A (BPA) Concentration Associates with Obesity and Insulin Resistance
The Journal of Clinical Endocrinology & Metabolism,2012,97(2):E223–E227
2012年02月01日
Context: Bisphenol A (BPA) is one of the world's highest-volume chemicals in use today. Previous studies have suggested BPA disturbs body weight regulation and promotes obesity and insulin resistance. But epidemiological data in humans were limited. Objective: Our objective was to determine whether BPA associates with obesity and insulin resistance. Design, Setting, and Participants: This cross-sectional study included 3390 adults aged 40 yr or older, in Songnan Community, Baoshan District, Shanghai, China. Main Outcome Measures: Questionnaire, clinical and biochemical measurements, and urinary BPA concentration were determined. Generalized overweight was defined as body mass index (BMI) of 24 to less than 28 kg/m2 and obesity was defined as BMI of 28 kg/m2 or higher. Abdominal obesity was defined as waist circumference at least 90 cm for men and at least 85 cm for women. Insulin resistance was defined as the index of homeostasis model assessment of insulin resistance higher than 2.50. Results: The participants in the highest quartile of BPA had the highest prevalence of generalized obesity [odds ratio (OR) = 1.50; 95% confidence interval (CI) = 1.15–1.97], abdominal obesity (OR = 1.28; 95% CI = 1.03–1.60), and insulin resistance (OR = 1.37; 95% CI = 1.06–1.77). In participants with BMI under 24 kg/m2, compared with the lowest quartile, the highest quartile of BPA increased the prevalence of insulin resistance by 94% (OR = 1.94; 95% CI = 1.20–3.14), but this association was not observed in those with BMI of 24 kg/m2 or higher. Conclusions: BPA was positively associated with generalized obesity, abdominal obesity, and insulin resistance in middle-aged and elderly Chinese adults.

【期刊论文】Exposure to bisphenol A is associated with low-grade albuminuria in Chinese adults
Kidney International,2012,81(11):1131-1139
2012年06月01日
Bisphenol A is an industrial chemical widely used in plastic products with a consequent exposure to humans. To assess whether exposure to bisphenol A is associated with renal disease, we searched for low-grade albuminuria in 3055 Chinese adults in the Shanghai metropolitan area aged 40 years or older. Using a value for urinary albumin-to-creatinine ratios <30 mg/g, we examined its association with urinary bisphenol A. Participants in the highest compared to the lowest quartile of urinary bisphenol A concentrations were significantly more likely to have low-grade albuminuria. Multivariate stepwise linear regression analysis, adjusted for potential confounding factors, showed that urinary bisphenol A was an independent determinant of the urinary albumin-to-creatinine ratio significantly associated with an increased risk of low-grade albuminuria with an adjusted odds ratio of 1.23 for the highest compared to the lowest concentration quartiles. This association was not modified by conventional risk factors such as age, gender, smoking, alcohol consumption, body mass index, hypertension, diabetes, and the estimated glomerular filtration rate. There was no significant relationship between bisphenol A and combined micro- and macroalbuminuria. Thus, our study lends support to a potential relation between bisphenol A exposure and an increased risk of low-grade albuminuria.

【期刊论文】Prevalence and Control of Diabetes in Chinese Adults
JAMA,2013,310(9):948-959
2013年09月04日
Importance Noncommunicable chronic diseases have become the leading causes of mortality and disease burden worldwide. Objective To investigate the prevalence of diabetes and glycemic control in the Chinese adult population. Design, Setting, and Participants Using a complex, multistage, probability sampling design, we conducted a cross-sectional survey in a nationally representative sample of 98 658 Chinese adults in 2010. Main Outcomes and Measures Plasma glucose and hemoglobin A1c levels were measured after at least a 10-hour overnight fast among all study participants, and a 2-hour oral glucose tolerance test was conducted among participants without a self-reported history of diagnosed diabetes. Diabetes and prediabetes were defined according to the 2010 American Diabetes Association criteria; whereas, a hemoglobin A1c level of <7.0% was considered adequate glycemic control. Results The overall prevalence of diabetes was estimated to be 11.6% (95% CI, 11.3%-11.8%) in the Chinese adult population. The prevalence among men was 12.1% (95% CI, 11.7%-12.5%) and among women was 11.0% (95% CI, 10.7%-11.4%). The prevalence of previously diagnosed diabetes was estimated to be 3.5% (95% CI, 3.4%-3.6%) in the Chinese population: 3.6% (95% CI, 3.4%-3.8%) in men and 3.4% (95% CI, 3.2%-3.5%) in women. The prevalence of undiagnosed diabetes was 8.1% (95% CI, 7.9%-8.3%) in the Chinese population: 8.5% (95% CI, 8.2%-8.8%) in men and 7.7% (95% CI, 7.4%-8.0%) in women. In addition, the prevalence of prediabetes was estimated to be 50.1% (95% CI, 49.7%-50.6%) in Chinese adults: 52.1% (95% CI, 51.5%-52.7%) in men and 48.1% (95% CI, 47.6%-48.7%) in women. The prevalence of diabetes was higher in older age groups, in urban residents, and in persons living in economically developed regions. Among patients with diabetes, only 25.8% (95% CI, 24.9%-26.8%) received treatment for diabetes, and only 39.7% (95% CI, 37.6%-41.8%) of those treated had adequate glycemic control. Conclusions and Relevance The estimated prevalence of diabetes among a representative sample of Chinese adults was 11.6% and the prevalence of prediabetes was 50.1%. Projections based on sample weighting suggest this may represent up to 113.9 million Chinese adults with diabetes and 493.4 million with prediabetes. These findings indicate the importance of diabetes as a public health problem in China.

【期刊论文】Low Serum Magnesium Level Is Associated with Microalbuminuria in Chinese Diabetic Patients
Int J Endocrinol,2013,2013():580685
2013年08月26日
Whether serum magnesium deficiency is independently associated with the prevalence of microalbuminuria is still unclear. The objective of the present study was to elucidate the association between serum magnesium and microalbuminuria in diabetic patients. A cross-sectional study was conducted in 1829 diabetic subjects (aged ≥ 40 years) from Shanghai, China. Subjects were divided into three groups according to serum magnesium tertiles. A first-voided early-morning spot urine sample was obtained for urinary albumin-creatinine ratio (UACR) measurement. Microalbuminuria was defined as 30 mg/g ≤ UACR < 300 mg/g. Overall, 208 (11.37%) of the study population had microalbuminuria, with similar proportions in both genders (P = 0.44). The prevalence of microalbuminuria in tertile 1 of serum magnesium was higher than the prevalence in tertile 2 and tertile 3 (15.98%, 9.72%, and 8.46%, resp.; P for trend <0.0001). After adjustment for age, sex, BMI, blood pressure, lipidaemic profile, HbA1c, eGFR, history of cardiovascular disease, HOMA-IR, antihypertensive and antidiabetic medication, and diabetes duration, we found that, compared with the subjects in tertile 3 of serum magnesium, those in tertile 1 had 1.85 times more likeliness to have microalbuminuria. We concluded that low serum magnesium level was significantly associated with the prevalence of microalbuminuria in middle-aged and elderly Chinese.

【期刊论文】Significant Coronary Stenosis in Asymptomatic Chinese With Different Glycemic Status
Diabetes Care ,2013,36(6):1687-1694
2013年06月01日
OBJECTIVE To evaluate coronary artery stenosis in early diabetes or prediabetes asymptomatic of myocardial ischemia in community-dwelling Chinese adults. RESEARCH DESIGN AND METHODS Age- and sex-matched participants with normal glucose regulation (NGR), prediabetes, or diabetes diagnosed within 5 years, asymptomatic of coronary artery disease (CAD), were randomly selected from a community-dwelling Chinese population aged 40–60 years. Dual-source computed tomography coronary angiography was used to evaluate the existence and extent of coronary stenosis, which was considered significant if >50% narrowing of vessel lumen was detected. RESULTS After excluding uninterpretable segments attributable to motion artifacts, a total of 135 participants with NGR, 132 with prediabetes, and 134 with diabetes participated in data analysis. Significant coronary stenosis was detected in 10 (7.4%), 10 (7.6%), and 22 (16.4%) individuals with NGR, prediabetes, and diabetes, respectively (P for trend = 0.029). Diabetes, rather than prediabetes, was associated with a significant 2.34-fold elevated risk [odds ratio (OR) 2.34 (95% CI 1.01–5.43); P = 0.047] of significant coronary stenosis as compared with that associated with NGR. Levels of glucose evaluation were independently and significantly associated with risks of significant coronary stenosis in diabetes. Each 1-SD increase in fasting plasma glucose, 2-h postload plasma glucose, and HbA1c conveyed 2.11-fold, 1.73-fold, and 1.81-fold higher risks of significant coronary stenosis, respectively, after adjustment for other conventional cardiovascular risk factors. CONCLUSIONS Using a noninvasive CAD diagnostic modality such as dual-source computed tomography coronary angiography, we detected a markedly elevated risk of significant coronary stenosis with early diabetes in asymptomatic Chinese adults. The prevalence of diabetes is increasing at an alarming rate and is projected to more than double in 2030 (1). China recently has been recognized as the world’s new diabetes capital after a nationwide survey found a prevalence of 9.7% and an absolute number of 92.4 million diabetic adults in mainland China (2). People with diabetes have a two-fold to three-fold increase in cardiovascular risks compared with nondiabetic individuals (3,4). However, because of various causes including neurologic complications (5,6), myocardial ischemia including myocardial infarction is often silent in diabetic patients (7–9), which results in a delayed diagnosis, missed opportunities for treatment, and a poor prognosis (10). Therefore, early detection of coronary artery disease (CAD) before symptoms occur using a noninvasive diagnostic modality such as multislice computed tomography (CT) coronary artery angiography at a time when patients could benefit most from intensive medical intervention might be critical to reducing cardiovascular morbidity and mortality in diabetes. Nevertheless, previous studies included subjects mostly at an advanced stage of their diabetes or consecutive patients who presented to the outpatient clinic (11–14). There have been limited data on coronary atherosclerosis in asymptomatic early diabetes or prediabetes. Therefore, the objective of this study was to estimate the prevalence of significant coronary stenosis, defined as >50% luminal narrowing measured by coronary CT angiography (CTA) and to compare that in normal glucose regulation (NGR) with that in early diabetes or prediabetes in community-dwelling Chinese adults without overt CAD symp

【期刊论文】Autonomic dysfunction assessed by EZSCAN and subclinical atherosclerosis
J Diabetes. ,2014,6(5):409-16
2014年03月27日
Background: The present study aimed to explore the association between autonomic dysfunction and measurements of atherosclerosis in a middle-aged and elderly Chinese population. Methods: A population-based cross-sectional study was performed in Shanghai, China, from March to August 2010, with 5076 participants included in the analysis. Autonomic function was assessed by a novel EZSCAN test based on sudomotor function analysis. Carotid intima-media thickness (CIMT) was measured using B-mode ultrasonography and brachial-ankle pulse wave velocity (ba-PWV) was measured using an autonomic device. Participants were divided into three groups based on EZSCAN values: Group 1: EZSCAN 0-24; Group 2, EZSCAN 25-49; and Group 3, EZSCAN 50-100. These groups denoted autonomic dysfunction risk groups as follows: no risk, moderate risk and high risk, respectively. Results: The prevalence of elevated CIMT and ba-PWV increased markedly with increasing EZSCAN values (elevated CIMT 7.4%, 17.5%, and 29.7%, elevated ba-PWV 3.2%, 19.7%, and 36.5%, in Groups 1, 2, and 3, respectively; both Ptrend < 0.0001). Logistic regressions revealed that EZSCAN values ≥50 were associated with a non-significantly higher risk of elevated CIMT (odds ratio [OR] = 1.43; 95% confidence interval [CI] 0.98-2.07) and a significantly higher risk of elevated ba-PWV (OR = 2.16; 95% CI 1.25-3.71) compared with EZSCAN values <25, after controlling for conventional risk factors. Conclusion: A higher EZSCAN value (≥50), an index of high autonomic dysfunction risk, was associated with an increased risk of elevated ba-PWV and CIMT. Such associations were partially explained by traditional atherosclerotic risk factors.

Objective Obesity and insulin resistance are risk factors for cardiovascular diseases. Whether insulin-sensitive obese individuals are at higher risk for cardiovascular diseases is still debated. We aim to investigate whether insulin-sensitive obesity associates with prevalent cardiovascular diseases and 10-year coronary heart disease (CHD) risk. Research design and methods At the baseline of the Risk Evaluation of cAncers in Chinese diabeTic Individuals: a lONgitudinal (REACTION) study, 211,641 participants aged 40 years or older were recruited from 25 communities across the China mainland, in 2011 to 2012. Participants were categorized by insulin-sensitive/resistant and general/abdominal obese status. Cardiovascular diseases included CHD, stroke, and myocardial infarction. Framingham risk score (FRS) was calculated according to National Cholesterol Education Program-Adult Treatment Panel III and FRS greater than 20% or cardiovascular diseases were identified as high risk for 10-year CHD. Results Controlling for potential confounders, compared with insulin-sensitive normal weight individuals, insulin-sensitive general obese individuals had increased risks for prevalent cardiovascular diseases (men: OR, 2.55, 95% CI, 2.04–3.18; women: 1.73, 1.45–2.06) and 10-year Framingham risk for CHD (men: 2.26, 1.86–2.76; women: 1.73, 1.46–2.06). Compared with insulin-sensitive normal waist subgroup, insulin-sensitive abdominal obesity was associated with higher risks for prevalent cardiovascular diseases (men: 1.32, 1.20–1.46; women: 1.36, 1.27–1.47) and 10-year Framingham risk for CHD (men, 1.34, 1.23–1.45; women, 1.37, 1.27–1.47). Conclusion Both general and abdominal obesity were associated with elevated prevalent cardiovascular diseases and 10-year CHD risk, regardless of the presence or absence of insulin resistance.

Background Increasing studies have suggested that albuminuria might be an important risk factor for peripheral artery disease (PAD). However, studies focusing on the association between low-grade albuminuria and PAD are limited. It would be of great interest to elucidate the association between low-grade albuminuria and PAD in diabetic subjects. Methods A cross-sectional study was conducted in 1386 diabetic subjects (age ≥ 40 years) with normal urinary albumin levels from Shanghai, China. A first voided early morning spot urine sample was obtained for urinary albumin and creatinine measurements. Subjects were divided into three groups according to sex-specific cutoff points of urinary albumin–creatinine ratio (UACR) tertiles. Subjects in the upper tertile of UACR were classified as having low-grade albuminuria. PAD was defined by ankle–brachial index (ABI) <0.9 or >1.4. Results Overall, 106 (7.7%) of the study population had PAD. The prevalence of PAD in tertile 3 of UACR was higher than the prevalence in tertile 2 and tertile 1 (10.2%, 6.4% and 6.4%, respectively; P < 0.05). A fully adjusted logistic regression analysis revealed that compared with subjects in tertile 1 of normal UACR, those in tertile 3 had 1.7-fold increased risk for the presence of PAD. Conclusions In diabetic patients, high normal UACR level, which is below the current cutoff point of microalbuminuria, was associated with the increased prevalence of PAD. It suggested that low-grade albuminuria might be an early marker for the detection of PAD in diabetic patients. Previous article in issue

The fatty liver index (FLI), which is an algorithm based on waist circumference, body mass index (BMI), triglyceride, and gamma-glutamyl-transferase (GGT), was initially developed to detect fatty liver in Western countries. Our study aimed to evaluate the accuracy and optimal cut-off point of the FLI for predicting nonalcoholic fatty liver disease (NAFLD) in middle-aged and elderly Chinese. This cross-sectional study included 8626 Chinese adults aged 40 years or above recruited from Jiading District, Shanghai, China. Anthropometric and biochemical features were collected by a standard protocol. NAFLD was diagnosed by hepatic ultrasonography. The accuracy and cut-off point of the FLI to detect NAFLD were evaluated by area under the receiver operator characteristic curve (AUROC) and the maximum Youden index analysis, respectively. The AUROC of the FLI for NAFLD was 0.834 (95% confidence interval: 0.825-0.842), and larger than that of its each individual component [0.786 (0.776-0.796), 0.783 (0.773-0.793), 0.727 (0.716-0.739), and 0.707 (0.695-0.719) for waist circumference, BMI, triglyceride, and GGT, respectively] (all P < 0.001). The optimal cut-off point of the FLI for diagnosing NAFLD was 30 with the maximum Youden Index of 0.51, achieving a high sensitivity of 79.89% and a specificity of 71.51%. The FLI-diagnosed NAFLD individuals were in worse metabolic characteristics (waist circumference, BMI, blood pressure, serum lipids, and aminotransferases) than ultrasonography-diagnosed NAFLD patients (all P < 0.05).The FLI could accurately identify NAFLD and the optimal cut-off point was 30 in middle-aged and elderly Chinese. As FLI-diagnosed NAFLD patients were in worse metabolism, much attention should be paid to the metabolic controls and managements of NAFLD.
