“…The prevalence rate of MS found in our study was similar to that reported by Hwang et al, 18 and we therefore believe that males and older persons have a higher prevalence rate of MS in Taiwan. Previous studies have reported that MS, 12,24,25 higher BMI values and hyperlipidemia in subjects are associated with hepatic steatosis. 26,27 Hepatic steatosis, even nonalcoholic steatohepatitis (NASH), is a liver disease that occurs in the absence of alcohol abuse and is frequently related to MS and type 2 diabetes.…”

“…26,27 Hepatic steatosis, even nonalcoholic steatohepatitis (NASH), is a liver disease that occurs in the absence of alcohol abuse and is frequently related to MS and type 2 diabetes. 12 We have previously reported that the severity of hepatic steatosis as assessed by ultrasound (B-mode, 3.5 MHz convex transducer) is significantly correlated with the results of hepatic enzyme tests such as AST, ALT and GGT (Po0.001); 15 however, whether hepatic steatosis can lead to abnormal hepatic enzyme test results remains controversial. [27][28][29] Regarding the relationship between MS and abnormal liver function, Miyatake et al…”

“…However, Miyatake et al 12 used the MS criteria for Japanese to subjects without syndrome, Nannipieri et al 14 selected subjects from a population-based diabetes survey, Wannamethee et al 13 surveyed nondiabetic men aged 60-79 years and Hsiao et al mentioned evaluating alanine aminotransferase (ALT) and hepatic fat content by ultrasound in patients with MS. In addition, the prevalence of MS in Taiwan varies in different populations and when applying different criteria.…”

Background: Metabolic syndrome (MS) is considered a cause of abnormal deposition of fat into hepatocytes, which might be associated with hepatic steatosis or abnormal liver function. Objective: The aim of this study was to explore the factors associated with MS and the relationship between MS and abnormal aspartate aminotransferase (AST), alanine aminotransferase (ALT) and g-glutamyl transferase (GGT) levels in Taiwanese subjects without chronic hepatitis B (CHB) or C (CHC). Subjects: We enrolled 2539 Taiwanese adults without CHB or CHC (age range: 16-88 years old) and investigated the factors related to MS using the NCEP-ATP (National Cholesterol Education Program-Adult Treatment Panel) III criteria; body mass index (BMI) was measured using Asia-Pacific criteria. Results: The prevalence rate of MS in Taiwanese adults without CHB or CHC was 16.9% using the modified ATP III criteria and 15.4% using the International Diabetes Federation criteria. Males had a significantly higher prevalence rate than females (Po0.001), and subjects with MS were significantly older and had significantly higher BMI values and AST, ALT and GGT levels (all Po0.001). In univariate analyses, the abnormality of liver function test results were related to gender, level of fasting sugar, systolic blood pressure, triglyceride, high-density lipoprotein, BMI and MS (all Po0.05). Multivariate analysis showed that the male gender, a higher BMI value and MS were related to abnormal liver function test results. The cutoff value for ALT in relation to MS is 31 IU l À1 for male and 18 IU l À1 for female.

“…Since the exercise intensity at VT is not harmful to cardiovascular function, it can be safely applied to patients with myocardial infarction as an exercise prescription [4]. We have previously reported that aerobic exercise level was significantly lower in subjects with metabolic syndrome than that in subjects without the syndrome [5], and the prevalence of metabolic syndrome was significantly higher in subjects with cigarette smoking than that in subjects without cigarette smoking [6]. However, the relationship between cigarette smoking and aerobic exercise level defined by VT is not fully discussed.…”

The link between cigarette smoking and ventilatory threshold (VT) was investigated. We used data for 407 men and 418 women not taking medication. Habits of cigarette smoking were obtained through interviews by well-trained staff. The influence of cigarette smoking on oxygen uptake, work rate, and heart rate at VT was evaluated. Oxygen uptake at VT in women and work rate at VT in men with cigarette smoking were significantly lower than in subjects without cigarette smoking after adjusting for age. The differences of parameters at VT did not reach significant levels after adjusting for age and exercise habits in both sexes. However, in women without exercise habits, there was significant difference of oxygen uptake at VT between women with and without cigarette smoking after adjusting for age [cigarette smoking (?): 11.5 ± 1.8 ml/ kg/min, cigarette smoking (-): 12.4 ± 2.1 ml/kg/min, p = 0.0006]. The number of cigarettes smoked per day and the Brinkman Index were not clearly correlated with oxygen uptake at VT. A combination of promoting exercise habits and prohibiting cigarette smoking might be recommended for improving the aerobic exercise level, especially in women.
