Mortality trends in chronic liver disease and cirrhosis from 1981 to 2015 in Taiwan.

BACKGROUND: Globally, the morbidity and mortality rates for chronic liver disease and cirrhosis are increasing. The National Viral Hepatitis Therapy Program in Taiwan was implemented in 2003, but evidence regarding the program's effect on the trends of mortality for chronic liver disease and cirrhosis is limited. METHODS: We analyzed mortality rates for chronic liver disease and cirrhosis in Taiwan for the period from 1981 to 2015. An autoregressive age-period-cohort model was used to estimate age, period, and cohort effects. RESULTS: Age-adjusted mortality rates for chronic liver disease and cirrhosis all displayed a flat but variable trend from 1981 to 2004 and a decreasing trend thereafter for both sexes. The age-period-cohort model revealed differential age gradients between the two sexes; mortality rates in the oldest age group (90-94 years) were 12 and 66 times higher than those in the youngest age group (30-34 years) for men and women, respectively. The period effects indicated that mortality rates declined after 2004 in both sexes. Mortality rates decreased in men but increased in women in the 1891-1940 birth cohorts and increased in both sexes in the birth cohorts from 1950 onward. CONCLUSIONS: The National Viral Hepatitis Therapy Program in Taiwan may have contributed to the decrease in mortality rates for chronic liver disease and cirrhosis in adulthood.

Opposite association between diabetes, dyslipidemia, and hepatocellular carcinoma mortality in the middle-aged and elderly.

UNLABELLED: Limited data exist regarding metabolic risk factors for deaths from hepatocellular carcinoma (HCC) in aging individuals. We investigated the association between diabetes, dyslipidemia, and HCC mortality in those aged 40 years or more (middle-aged and elderly). In this prospective cohort study based on nationwide health screening units, we consecutively followed middle-aged and elderly participants who had no chronic hepatitis B or C virus infection and received health screening from January 1 1998 to December 31 2008. There were 235 deaths from HCC among 50,080 individuals, ascertained by validated death certificates and the national death registry. Diabetes (adjusted hazard ratio [HR], 3.38; 95% confidence interval [CI], 2.35 to 4.86) was positively associated with deaths from HCC. However, hypertriglyceridemia (HR, 0.38; 95% CI, 0.26 to 0.55) and hypercholesterolemia (HR, 0.50; 95% CI, 0.37 to 0.67) were inversely associated with HCC mortality. The above significant associations remained in the lag time analyses, applied to check for reverse causation. Metabolic syndrome, as defined by the American Heart Association / National Heart Lung Blood Institute criteria (HR, 0.63; 95% CI, 0.46 to 0.86) or by the International Diabetes Federation criteria (HR, 0.62; 95% CI, 0.43 to 0.89), was inversely associated with deaths from HCC, especially in men. CONCLUSION: Middle-aged and elderly individuals, once having diabetes, deserve HCC surveillance to reduce HCC mortality. More research is needed to elucidate why having baseline dyslipidemia relates to lower future HCC mortality.

Plasma zinc α2-glycoprotein levels are elevated in smokers and correlated with metabolic syndrome.

BACKGROUND: Smoking is a strong risk factor of metabolic syndrome. Zinc α2-glycoprotein (ZAG) is a protein involved in metabolic syndrome. This study aims to investigate the effect of smoking on plasma ZAG levels and its relations to metabolic syndrome. MATERIALS AND METHODS: A group of 41 cigarette smokers and 47 non-smokers were enrolled. ZAG levels were measured to correlate to participants' demographic and metabolic parameters. RESULTS: Plasma ZAG levels of smokers were higher than those of controls (P < 0.0001). Plasma ZAG levels were positively correlated with male gender (P = 0.0002), number of cigarettes smoked per day (P < 0.0001), smoking duration in years (P < 0.0001), smoking index (P < 0.0001) and nicotine dependence score (P < 0.0001). In the multiple regression analysis, smoking was a strong independent factor affecting plasma ZAG levels (P = 0.0034). Plasma ZAG levels elevated progressively with the number of metabolic syndrome components (P = 0.0143). In the multiple regression analysis, plasma ZAG was an independent factor for metabolic syndrome. CONCLUSIONS: Plasma ZAG levels are high in smokers and correlate with metabolic syndrome. Our results indicate ZAG is an independent risk factor, but also interacted with smoking, for the metabolic syndrome.

Family experience with difficult decisions in end-of-life care.

OBJECTIVE: The difficult decisions encountered by family caregivers in the process of care for patients with terminal cancer are seldom studied. Investigating their experiences with difficult decisions may help relieve their psychological distress. The purpose of this study was to determine the frequency and difficulty of decisions experienced in end-of-life care and to identify related factors. METHODS: A cross-sectional study using questionnaires was conducted with family caregivers of patients who died of cancer in a university hospital. Difficulty of decisions and relevant influencing variables including demographic data, knowledge in palliative care and the Natural Death Act, and beliefs on the Natural Death Act were measured. RESULTS: A total of 302 bereaved family caregivers were included in the final analysis. The most difficult decisions commonly encountered in both hospice and non-hospice wards related to truth telling, place of care, and alternative treatments. Logistic regression analysis demonstrated that older age (odds ratio = 0.92, 95% confidence interval = 0.89-0.95), not being the main family caregiver (0.20, 0.06-0.62), and less perception of burdens regarding the Natural Death Act (0.61, 0.37-0.99) were negatively correlated with the difficulty of decisions. CONCLUSIONS: Families frequently encountered difficult decisions while caring for terminally ill loved ones. Better communication with family members, particularly the main caregiver, to diminish negative perceptions of the Natural Death Act could help to decrease psychological distress.

Changes of serum adiponectin and soluble intercellular adhesion molecule-1 concentrations after smoking cessation.

BACKGROUND: This study aims to investigate the effect of increased serum adiponectin concentration during smoking cessation on soluble intercellular adhesion molecule-1 (sICAM-1) concentration. METHODS: One hundred and sixty-six eligible smokers were assessed at baseline and were followed up at the 1st, 5th, and 9th weeks after smoking cessation. Demographic data, body weight and blood pressure of these participants were obtained; serum glucose biochemical data, sICAM-1 and adiponectin concentrations were measured. Repeated measures analysis paired t-tests and generalized estimating equations for balanced repeated measures were used for statistical analyses. RESULTS: Forty-one individuals completed the 2-month smoking cessation program. The mean cigarette consumption dramatically decreased (p<0.0001) and the cotinine concentration also decreased significantly (p<0.0001) among the quitters. Serum adiponectin concentration significantly increased (p=0.0186) and sICAM-1 significantly decreased (p<0.0001) in quitters after smoking cessation. The elevation of serum adiponectin concentration significantly correlated with lowering of sICAM-1 (p=0.0001) concentration. Body weight changes at the end of 2-month smoking cessation was inversely correlated with adiponectin increment from baseline (p=0.0003). CONCLUSIONS: An increase in serum adiponectin concentration is an independent factor correlated with lowering of sICAM-1 concentration during smoking cessation.

The potential prolonged effect at one-year follow-up after 18-month randomized controlled trial of a 90 g/day low-carbohydrate diet in patients with type 2 diabetes.

OBJECTIVES: To evaluate the effect at a one-year follow-up after an 18-month randomized controlled trial (RCT) of 90 gm/day low-carbohydrate diet (LCD) in type 2 diabetes. RESEARCH DESIGN AND METHODS: Eighty-five poorly controlled type 2 diabetic patients with an initial HbA1c ≥ 7.5% who have completed an 18-month randomized controlled trial (RCT) on 90 g/day low-carbohydrate diet (LCD) were recruited and followed for one year. A three-day weighted food record, relevant laboratory tests, and medication effect score (MES) were obtained at the end of the previous trial and one year after for a total of 30 months period on specific diet. RESULTS: 71 (83.5%) patients completed the study, 35 were in TDD group and 36 were in LCD group. Although the mean of percentage changes in daily carbohydrate intake was significantly lower for those in TDD group than those in LCD group (30.51 ± 11.06% vs. 55.16 ± 21.79%, p = 0.0455) in the period between 18 months and 30 months, patients in LCD group consumed significantly less amount of daily carbohydrate than patients in TDD group (131.8 ± 53.9 g vs. 195.1 ± 50.2 g, p < 0.001). The serum HbA1C, two-hour serum glucose, serum alanine aminotransferase (ALT), and MES were also significantly lower for the LCD group patients than those in the TDD group (p = 0.017, p < 0.001, p = 0.017, and p = 0.008 respectively). The mean of percentage changes of HbA1C, fasting serum glucose, 2 h serum glucose, as well as serum cholesterol, triglyceride, low-density lipoprotein, ALT, creatinine, and urine microalbumin, however, were not significantly different between the two groups (p > 0.05). CONCLUSIONS: The one-year follow-up for patients on 90 g/d LCD showed potential prolonged and better outcome on glycaemic control, liver function and MES than those on TDD for poorly controlled diabetic patients.

Pregnancy outcome of women in the vicinity of nuclear power plants in Taiwan.

The purpose of the study was to investigate whether proximity to nuclear power plants may increase the risk of abnormal pregnant outcomes among the resident women. In this ecological study, data were used from the Health Services Birth Reports Database established by the Bureau of Health Promotion, National Department of Health, Taiwan, in 2001-2004. Chi-square-tests were carried out to investigate the "Plant-vicinity" and "Non plant-vicinity" group in terms of pregnancy outcome. Additionally, logistic regression was performed to investigate whether residence in the vicinity of a nuclear power plant was related to any abnormal pregnancy results. Based on data from 5,679 included subjects, no difference was observed between pregnancy outcomes of the "Plant-vicinity" and "Non plant-vicinity" groups. After accounting for possible confounders, the adjusted odds ratios were 1.20 (95% CI = 0.56-2.56) for stillbirth, 1.21 (95% CI = 0.95-1.53) for premature birth, 1.04 (95% CI = 0.79-1.37) for low birth weight, and 1.58 (95% CI = 0.85-2.93) for congenital deficiencies, respectively, when comparing the "Plant-vicinity" with the "Non plant-vicinity" group. The results of the study indicate that residence in the vicinity of a nuclear power plant is not a significant factor which will cause abnormal health situations during pregnancy.

Effect of a 90 g/day low-carbohydrate diet on glycaemic control, small, dense low-density lipoprotein and carotid intima-media thickness in type 2 diabetic patients: An 18-month randomised controlled trial.

AIM: This study explored the effect of a moderate (90 g/d) low-carbohydrate diet (LCD) in type 2 diabetes patients over 18 months. METHODS: Ninety-two poorly controlled type 2 diabetes patients aged 20-80 years with HbA1c ≥7.5% (58 mmol/mol) in the previous three months were randomly assigned to a 90 g/d LCD r traditional diabetic diet (TDD). The primary outcomes were glycaemic control status and change in medication effect score (MES). The secondary outcomes were lipid profiles, small, dense low-density lipoprotein (sdLDL), serum creatinine, microalbuminuria and carotid intima-media thickness (IMT). RESULTS: A total of 85 (92.4%) patients completed 18 months of the trial. At the end of the study, the LCD and TDD group consumed 88.0±29.9 g and 151.1±29.8 g of carbohydrates, respectively (p < 0.05). The 18-month mean change from baseline was statistically significant for the HbA1c (-1.6±0.3 vs. -1.0±0.3%), 2-h glucose (-94.4±20.8 vs. -18.7±25.7 mg/dl), MES (-0.42±0.32 vs. -0.05±0.24), weight (-2.8±1.8 vs. -0.7±0.7 kg), waist circumference (-5.7±2.7 vs. -1.9±1.4 cm), hip circumference (-6.1±1.8 vs. -2.9±1.7 cm) and blood pressure (-8.3±4.6/-5.0±3 vs. 1.6±0.5/2.5±1.6 mmHg) between the LCD and TDD groups (p<0.05). The 18-month mean change from baseline was not significantly different in lipid profiles, sdLDL, serum creatinine, microalbuminuria, alanine aminotransferase (ALT) and carotid IMT between the groups. CONCLUSIONS: A moderate (90 g/d) LCD showed better glycaemic control with decreasing MES, lowering blood pressure, decreasing weight, waist and hip circumference without adverse effects on lipid profiles, sdLDL, serum creatinine, microalbuminuria, ALT and carotid IMT than TDD for type 2 diabetic patients.

Validation of Assaying Carcinoembryonic Antigen in Human Serum by Using Immunomagnetic Reduction.

Immunomagnetic reduction (IMR) is a method to assay biomolecules by utilizing antibody functionalized magnetic nanoparticles. For clinical validation, important analytic performances of assaying carcinoembryonic antigen (CEA) using IMR are characterized. Furthermore, IMR is applied to assay carcinoembryonic antigen (CEA) in human serum for clinical validation. A total of 118 healthy controls and 79 patients with colorectal cancer (CRC) are recruited in this study. For comparison, assays using chemiluminometric immunoassay (CLIA) are also done for quantizing CEA in these serum samples. The results reveal a high correlation in terms of serum CEA concentration detected via IMR and CLIA is found (r = 0.963). However, IMR shows higher clinical sensitivity and specificity than those of CLIA. Moreover, the rate of false positives for smoking subjects is clearly reduced through the use of IMR. All the results demonstrate IMR is a promising alternative assay for serum CEA to diagnose CRC.

Tour leaders with detailed knowledge of travel-related diseases play a key role in disease prevention.

In Taiwan, group tours are a popular mode of international travel; hence, group tour leaders must ensure traveler safety and health. This study identified factors influencing tour leaders' willingness to recommend pretravel medical consultation and vaccination.A cross-sectional questionnaire survey was administered to tour leaders from January 2011 to December 2012. Multivariate logistic regression analyses were performed to estimate the odds ratios of having a positive attitude and willingness based on different knowledge scores of the tour leaders after adjustments for age, sex, education level, and seniority.Tour leaders with a more detailed knowledge of both travel-related infectious and noninfectious diseases demonstrated a higher willingness to receive vaccination. They believed that consultation at travel clinics before travel can improve travelers' health (P < .05).This study supports the importance and effectiveness on educating tour leaders' knowledge about travel-related diseases to improve health care for travelers.

Prevalence and risks of chronic airway obstruction: a population cohort study in taiwan.

BACKGROUND: This study investigated the prevalence, incidence, and hospitalization for chronic airway obstruction (CAO) in a population cohort. METHODS: Medical reimbursement claims from 1996 to 2002 based on a 1996 insured cohort of 167,372 persons from National Health Insurance, Taiwan, were used. We presented the chronological trends of CAO (International Classification of Diseases, Ninth Revision code 496) and the relationships between the CAO severity and age, sex, urbanization, and hospitalization and comorbidity for the population >/= 40 years old. RESULTS: The overall average annual prevalence and incidence rates were 2.48/100 and 0.66/100, respectively, for the population, among 4,568 patients with CAO cared during the study period. For the population aged >/= 70 years, the prevalence rates had a peak of 8.83/100 in 1998 and afterward remained a plateau until 2002. The corresponding incidence decreased from 2.48/100 to 1.62/100, and the hospitalization rate for them had a peak of 2.22/100 in 1999. The multivariate logistic regression analysis showed that the risk of hospitalization for CAO was higher for patients with the comorbidity of renal failure, coronary artery disease, and pneumonia and influenza, but lower with skin and joint disorders. CONCLUSIONS: The national insurance program promotes patient care and provides a proper pathway for surveillance and identification of CAO.

Metabolic syndrome is related to nonalcoholic steatohepatitis in severely obese subjects.

BACKGROUND: Metabolic syndrome (MetS) and nonalcoholic fatty liver disease (NAFLD), ranging from simple steatosis to steatohepatitis (NASH), have become important health issues in obese subjects. In this study, we investigated the relationship between MetS and NASH in severely obese subjects. METHODS: A total of 111 non-alcoholic obese patients who underwent laparoscopic bariatric surgery (BMI 45.4 +/- 5.7 kg/m2) were enrolled from February to September 2004 in a referral center in North Taiwan. MetS and its individual components were defined using the American Heart Association/National Heart, Lung, and Blood Institute criteria. Based on liver biopsy during surgery, subjects were classified into either having NASH or not. The relationship among NASH, adiponectin, insulin resistance, MetS and its individual components was examined using a multivariate logistic regression analysis. RESULTS: The prevalence of NASH and MetS in these subjects was 79.3% and 68.5%, respectively. Using a multivariate logistic regression analysis with NASH as the outcome variable, odds ratio (OR) of NASH for subjects with MetS versus without MetS was 2.96 (95% CI = 1.14-7.68) adjusted for age, gender, and BMI. Also, high blood pressure (OR = 2.97, 1.31-6.73) and high fasting glucose (OR = 2.94, 1.13-7.67) were independently associated with NASH after adjustment for age, gender, and BMI. Insulin resistance measured as HOMA-IR and serum adiponectin level were not significantly different between the NASH and non-NASH group. CONCLUSION: MetS and NASH were common in severely obese Taiwanese adults. Presence of MetS, high blood pressure, and high fasting glucose was independently related to increased risk of NASH. The underlying mechanism deserves to be explored in the future.

Cancer incidence in the vicinity of nuclear power plants in Taiwan: a population-based study.

Numerous antinuclear demonstrations reveal that the public is anxious about the potential health effects caused by nuclear power plants. The purpose of this study is to address the question "Is there a higher cancer incidence rate in the vicinity of nuclear power plants in Taiwan?" The Taiwan Cancer Registry database from 1979 to 2003 was used to compare the standardized incidence rate of the top four cancers with strong evidence for radiation risks between the "plant-vicinity" with those "non-plant-vicinity" groups. All cancer sites, five-leading cancers in Taiwan, and gender-specific cancers were also studied. We also adopted different observation time to compare the incidence rate of cancers between two groups to explore the impact of the observation period. The incidences of leukemia, thyroid, lung, and breast cancer were not significantly different between two groups, but cervix uteri cancer showed higher incidence rates in the plant-vicinity group. The incidence of cervical cancer was not consistently associated with the duration of plant operation, according to a multiyear period comparison. Although there was higher incidence in cervix cancer in the plant-vicinity group, our findings did not provide the crucial evidence that nuclear power plants were the causal factor for some cancers with strong evidence for radiation risks.

The Association between Total Protein and Vegetable Protein Intake and Low Muscle Mass among the Community-Dwelling Elderly Population in Northern Taiwan.

Sarcopenia, highly linked with fall, frailty, and disease burden, is an emerging problem in aging society. Higher protein intake has been suggested to maintain nitrogen balance. Our objective was to investigate whether pre-sarcopenia status was associated with lower protein intake. A total of 327 community-dwelling elderly people were recruited for a cross-sectional study. We adopted the multivariate nutrient density model to identify associations between low muscle mass and dietary protein intake. The general linear regression models were applied to estimate skeletal muscle mass index across the quartiles of total protein and vegetable protein density. Participants with diets in the lowest quartile of total protein density (<13.2%) were at a higher risk for low muscle mass (odds ratio (OR) 3.03, 95% confidence interval (CI) 1.37-6.72) than those with diets in the highest quartile (≥17.2%). Similarly, participants with diets in the lowest quartile of vegetable protein density (<5.8%) were at a higher risk for low muscle mass (OR 2.34, 95% CI 1.14-4.83) than those with diets in the highest quartile (≥9.4%). Furthermore, the estimated skeletal muscle mass index increased significantly across the quartiles of total protein density (p = 0.023) and vegetable protein density (p = 0.025). Increasing daily intakes of total protein and vegetable protein densities appears to confer protection against pre-sarcopenia status.

High serum selenium levels are associated with increased risk for diabetes mellitus independent of central obesity and insulin resistance.

OBJECTIVE: Selenium is an essential micronutrient for human health. Although many observational and interventional studies have examined the associations between selenium and diabetes mellitus, the findings were inconclusive. This study aimed to investigate the relationship between serum selenium levels and prevalence of diabetes, and correlated the relationship to insulin resistance and central obesity. RESEARCH DESIGN AND METHODS: This was a hospital-based case-control study of 847 adults aged more than 40 years (diabetes: non-diabetes =1:2) in Northern Taiwan. Serum selenium was measured by an inductively coupled plasma-mass spectrometer. The association between serum selenium and diabetes was examined using multivariate logistic regression analyses. RESULTS: After adjusting for age, gender, current smoking, current drinking, and physical activity, the ORs (95% CI, p value) of having diabetes in the second (Q2), third (Q3), and fourth (Q4) selenium quartile groups were 1.24 (95% CI 0.78 to 1.98, p>0.05), 1.90 (95% CI 1.22 to 2.97, p<0.05), and 5.11 (95% CI 3.27 to 8.00, p<0.001), respectively, compared with the first (Q1) quartile group. Further adjustments for waist circumference and homeostatic model assessment-insulin resistance (HOMA-IR) largely removed the association of serum selenium levels with diabetes but not in the highest quartile (compared with Q1, Q3: 1.57, 95% CI 0.91 to 2.70, Q4: 3.79, 95% CI 2.17 to 6.32). CONCLUSIONS: We found that serum selenium levels were positively associated with prevalence of diabetes. This is the first human study to link insulin resistance and central obesity to the association between selenium and diabetes. Furthermore, the association between selenium and diabetes was independent of insulin resistance and central obesity at high serum selenium levels. The mechanism behind warrants further confirmation.

Relationship between chronic hepatitis B and metabolic syndrome: A structural equation modeling approach.

OBJECTIVE: Investigate the nature of the relationship between chronic hepatitis B virus (HBV) infection and metabolic syndrome among nondiabetic adults. METHODS: This was a cross-sectional analysis of 17,030 nondiabetic adults (7437 males and 9593 females; mean age, 36.0 ± 3.9 years) in northern Taiwan from 2008 to 2009. The associations of hepatitis B surface antigen (HBsAg) seropositivity with metabolic syndrome and cardio-metabolic parameters were assessed. A structural equation model was constructed to elucidate the pathways between chronic HBV infection and individual cardiometabolic risk factors. RESULTS: A total of 2982 (17.5%) participants were HBsAg-seropositive. Of the seropositive and seronegative subjects, 15.5 and 16.9% had metabolic syndrome, respectively. The HBsAg-seropositive subjects had a lower odds of having metabolic syndrome compared with the seronegative subjects irrespective of gender and age (OR: 0.76, 95% CI: 0.68-0.85). The inverse associations remained significant after adjusting for body mass index and serum alanine aminotransferase levels. HBsAg seropositivity was inversely associated with hypertriglyceridemia (OR: 0.59, 95% CI: 0.52-0.66), and low serum levels of high-density lipoprotein cholesterol (OR: 0.86, 95% CI: 0.79-0.93) after adjustments. The structural equation model revealed chronic HBV infection had a significant negative effect on dyslipidemia both in males (B = -0.054) and females (B = -0.064). CONCLUSIONS: The inverse relationship between chronic HBV infection and metabolic syndrome may be attributable to the net beneficial effects on lipid profiles.

Association of Non-alcoholic Fatty Liver Disease with Metabolic Syndrome Independently of Central Obesity and Insulin Resistance.

Non-alcoholic fatty liver disease (NAFLD) is an emerging chronic liver disease that may lead to liver cirrhosis and hepatocellular carcinoma. We aimed to determine the association between the prevalence of metabolic syndrome (MetS) and NAFLD severity using semi-quantitative ultrasonography (US). A total of 614 participants were recruited from the community. NAFLD was evaluated according to the ultrasonographic Fatty Liver Indicator (US-FLI), which is a semi-quantitative liver ultrasound score. Insulin resistance was estimated with the homeostasis model assessment index for insulin resistance (HOMA-IR). NAFLD and MetS were found in 53.7 and 17.3% of the participants, respectively. Linear relationships were found between the severity of NAFLD and waist circumference, fasting glucose, HOMA-IR, triglycerides, HDL-C and blood pressure. After adjusting for confounding factors, i.e., body mass index and HOMA-IR, the odds ratios for MetS were 3.64 (95% confidence interval (CI): 1.5-8.83) for those with mild NAFLD and 9.4 (95% CI: 3.54-24.98) for those with moderate-to-severe NAFLD compared to those without NAFLD. The combination of the HOMA-IR and US-FLI scores better differentiated MetS than the HOMA-IR alone. In addition to obesity, the severity of NAFLD and the HOMA-IR both play important roles in MetS. Whether NAFLD is a component of MetS warrants further research.

Serum Triglyceride Levels Independently Contribute to the Estimation of Visceral Fat Amount Among Nondiabetic Obese Adults.

Determining the visceral fat amount is important in the risk stratification for the prevention of type 2 diabetes and obesity-related disorders. The area-based measurement of visceral fat area (VFA) via magnetic resonance imaging (MRI) is an accurate but expensive and time-consuming method for estimating visceral fat amount. The aim of our study was to identify a practical predictive parameter for visceral obesity in clinical settings. In this cross-sectional study, we recruited 51 nondiabetic obese (body mass index [BMI] ≥ 27 kg/m²) adults in Taiwan (21 men and 30 women, mean age 35.6 ±â€Š9.2 years, mean BMI 33.3 ±â€Š3.9 kg/m²). VFA was quantified by a single-slice MRI image. Anthropometric indices and biochemical parameters including fasting plasma glucose, serum level of alanine aminotransferase, and lipid profiles were measured. The associations between different variables and VFA were analyzed by linear regression analysis. Increases in BMI, waist circumference, serum levels of alanine aminotransferase and triglycerides (TGs), and decreased serum levels of high-density lipoprotein cholesterol were correlated with larger VFA. After adjustment for age, sex, and anthropometric indices, only serum TG level remained as an independent correlate of VFA. Besides demographic and anthropometric indices, adding TG level may explain a greater variance of VFA. In stepwise multivariate regression analysis, male sex, age, waist circumference, and serum TG level remained significant predictors of VFA. In a subgroup analysis among subjects with BMI ≥30 kg/m², similar results were demonstrated and serum TG level remained as significant independent correlates of VFA in all of the predictive models. Among nondiabetic obese adults, serum TG level was positively associated with VFA. The combination of sex, age, anthropometric indices, and serum TG level may be used to estimate VFA in clinical settings.
