“…3 Taiwan, an economically developed country, also experienced a decrease in the prevalence of hypertension (age-adjusted prevalence: 26.6-23.5%, from 1993 to 2002) and a decrease in the mean BP in adults. 35 However, the prevalence of obesity is still increasing in Taiwanese children and adults, 20,36 and the trends of hypertension in children are consistent with the rate of increasing obesity. The following lists possible reasons for the inconsistent trends of hypertension between children and adults in Taiwan.…”

This study evaluates prevalence of hypertension in 1996 and 2006, and examines the relationship between hypertension and weight of Taiwanese young adolescents. Two cross-sectional surveys, administered in 1996 and 2006, to junior-high school in Taipei were included. Anthropometric and blood pressure were measured using standard methods, and structured questionnaire was used to collect personal history and lifestyle characteristics. Overweight and obesity are defined based on Taiwan's Department of Health criteria and bases pre-hypertension and hypertension on the 90th and 95th percentile distribution of blood pressure of the population of both surveys. The prevalence of pre-hypertension in Taiwan between 1996 and 2006 increased from 12.0 to 14.4% for boys and decreased from 9.5 to 9.4% for girls. Hypertension increased from 22.8-29.7% and 12.5-20.7% for both boys and girls, respectively. In 1996, compared with normal young adolescents, the risk of hypertension for overweight was 1.8 times higher for boys and 3.4 times for girls. However, the risk of hypertension for overweight in 2006 was 1.7 times higher for boys and 1.5 times higher for girls compared with normal. Every unit increment of body mass index and waist circumference was associated with 17-27% and 6-11% risk of hypertension in both genders in 1996, and was associated with 9-13% and 4% risk of hypertension among young adolescents in 2006, respectively. The prevalence of hypertension has increased significantly in young adolescents, especially for overweight. It is necessary to enrol young adolescents in weight management programs to prevent hypertension-related co-morbidities.

“…It is perhaps not surprising that NAFLD is frequently observed in obese people. As obesity is dramatically increasing in both Asian and Western populations, it is likely that obesity will become an increasingly important risk factor for elevated ALT concentration (Flegal et al, 2002;Thorburn, 2005;Ko et al, 2007;Pan et al, 2008).…”

Background/Objectives: Obesity has been identified as an important factor of elevated alanine aminotransferase (ALT), a surrogate of non-alcoholic fatty liver disease. We investigated the relationship between obesity and elevated ALT in the general Korean population. Subjects/Methods: The study sample was comprised of 3098 Korean adults who had participated in the 2005 Korean National Health and Nutrition Examination Survey. Obesity was assessed using body mass index (BMI). Overweight (23pBMIo25) and obese (BMIX25) were defined by the International Obesity Task Force for Asian adults. ALT was measured by enzymatic methods. Elevated ALT was defined as an enzyme activity 440 IU/l for men and 431 IU/l for women. Results: Among participants, 246 (12.7%) men and 86 (7.4%) women displayed elevated ALT. BMI was significantly higher in men and women with elevated ALT than those with normal ALT (Po0.0001). The unadjusted odds ratio (OR) for elevated ALT increased according to the degree of BMI in men (OR: 1.9, 95% confidence interval (CI): 1.25-2.93 in overweight vs OR: 5.01, 95% CI: 3.49-7.21 in obese; Po0.0001) and women (OR: 2.44, 95% CI: 1.24-4.82 vs OR: 3.94, 95% CI: 2.18-7.13; Po0.0001). This trend did not differ after adjustment for putative risk factors including alcohol intake in men (OR: 1.56 vs OR: 3.47, Po0.0001) and women (OR: 1.55 vs OR: 3.10, P ¼ 0.0015). Conclusion: BMI is implicated as a strong risk factor of elevated ALT in non-diabetic Korean adults.

Objective: Fe is an essential element for erythropoiesis and Hb synthesis. High Hb levels affect the blood's viscosity and are associated with cardiovascular dysfunction. The aim of the present study was to examine relationships of Hb and cardiometabolic abnormalities with the risk of alanine aminotransferase (ALT) elevation in adolescents. Design: A population-based, cross-sectional study. Setting: National Nutrition and Health Survey in Taiwan (2010Taiwan ( -2011. Subjects: Healthy adolescents aged 13-18 years. Results: In total, 1941 adolescents (963 boys and 978 girls) were entered in the study. The mean age was 15·3 (SD 0·1) years (boys, 15·3 (SD 0·1) years; girls, 15·2 (SD 0·1) years). ALT tertile cut-off points for boys were 11 and 16 U/l, and for girls were 9 and 12 U/l. Girls without dyslipidaemia and presenting in the highest quartile (Q1) of Hb (>13·6 g/dl) were 1·89 and 3·76 times more likely to have raised serum ALT (9 and >12 U/l, respectively) than the reference (lowest quartile of Hb (Q1), <12·4 g/dl). Moreover, for those girls with dyslipidaemia, serum ALT seemed to increase with an increase in Hb levels. Specifically, girls with dyslipidaemia and Hb levels of 12·4, 13·1 and 13·6 g/dl were, respectively, 2·86, 3·53 and 5·64 times more likely to have elevated serum ALT levels (>12 U/l) than the reference (Q1 of Hb, <12·4 g/dl). The only effect found in boys was for those who had dyslipidaemia and presenting in Q4 of Hb (>15·4 g/dl), who were 7·40 times more likely to have elevated serum ALT of >16 U/l than the reference (Q1 of Hb, <14·1 g/dl). Conclusions: Our findings suggest that an increased Hb level is a predictor of elevated serum ALT in adolescent girls with dyslipidaemia. Our study also highlights the importance of further research to establish cut-off points for Hb and its utility in diagnosing and preventing the onset of dyslipidaemia in adolescents.
