733 senior civil servants comprising 520 males and 213 females with a mean age of 44 years (range 25-56 years) were screened for their health status. The sample population comprised of 67.9% Malays, 22.5% Chinese, 9.1% Indians and 0.4% other ethnic origins. The subjects' medical histories were recorded and a full medical examination including anthropometric measurements (weight, height, waist and hip circumference), blood biochemistry and urine analysis, chest X-ray and electrocardiograms were done. The results obtained showed that 36.0% of the study population were overweight with 6.5% being obese. Of this 32.0% had central obesity. 15.2% of the subjects had systolic hypertension (systolic BP > or = 140 mmHg) whilst 27.6% had diastolic hypertension (diastolic BP > or = 90 mmHg). Hyperlipidaemia was common, with 75.2% subjects having raised cholesterol, 19.9% raised triglycerides, 50.2% raised LDL-C, 74.6% raised TC:HDL-C and 26.6% raised LDL:HDL-C. An elevated blood glucose was found in 8.4% subjects, whilst urine sugar was detected in only 2.6%, and a raised uric acid was found in 2.8% subjects. The prevalence of hypertension, raised blood glucose and hyperlipidaemia increased with age with more males affected than females. Although hypercholesterolaemia appeared more frequently amongst the Malays, the Indians, by comparison had the highest prevalence for a raised LDL:HDL-C ratio, a reflection of the increase in LDL-C and a concomitant decrease in HDL-C. The latter findings indicate that the Indians are at greater risk for the development of coronary heart disease than the Chinese and Malays. In addition, the mean levels of serum cholesterol found in this study seemed to have exceeded the levels found in populations in the industrialised countries such as the USA. There is thus an urgent need for more public health campaigns aimed at the reduction and control of such coronary risk factors.

The aim of this study was to evaluate the occurrence of obesity and arterial hypertension in patients suffering from vertigo, and/or tinnitus and/or hearing loss of unknown origin. 48 patients (25 women and 23 men) were included into this study. All patients had a negative previous medical history of any metabolic, cardiovascular or neurological disorders. Our results were compared to the control group of 31 healthy persons (16 women and 15 men). All subjects had a complete neurootologic examination, appropriate audiometric and vestibular studies. In most cases inner ear pathology was recognised. BMI, systolic and diastolic blood pressure were measured in all cases. Patients were overweight significantly more often comparing to the control group. Systolic and diastolic hypertension was found significantly more often in men from the patients than control group.

Hyperinsulinemia and other associated metabolic factors, including hyperglycemia, dyslipidemia, hypertension, and central obesity lead to increased cardiovascular risk and indicate a metabolic syndrome. Levels of fasting insulin were measured in an ethnic Gipsy minority group (n=149) and compared to the majority Slovak population (n=197). The average insulin level was significantly increased in the minority group with a 21% risk value vs 5%. Hyperglycemia was equal in both groups (17% in Gipsy group, 16% in majority group). The incidence of other risk factors for cardiovascular disease and metabolic syndrome is greater in the Gipsy group (47% vs 38%--hypertriacylglycerolemia, 62% vs 46%--HDL-cholesterol level below safety limit, 16% vs 10%--systolic hypertension, 20% vs 11%--diastolic hypertension, 36% vs 22%--obesity). The results of hyperinsulinemia, hypertriacylglycerolemia, hypo-HDL-cholesterolemia, hypertension and obesity indicate, that the Gipsy population is at higher risk for cardiovascular disease. (Tab. 1, Fig. 1, Ref. 12.).

To determine whether hypertension and overweight status are associated with increased carotid intimal-medial thickness (cIMT) in children, vascular ultrasonography was performed in newly diagnosed hypertensive patients ( n=53) and normotensive controls ( n=33). Hypertensive subjects were identified either by referral or by systematic school-based hypertension screening. Hypertension was defined as blood pressure above the 95th percentile based on current Task Force criteria, and overweight was defined as body mass index (BMI) >25 kg/m(2). cIMT was assessed by high-resolution vascular ultrasonography of the distal common carotid artery. Hypertensive subjects had a higher cIMT than normotensive subjects (0.62 vs. 0.53 mm, P<0.00001). This difference remained significant after controlling for the effects of gender, race, age, height, weight, and BMI. Similarly, overweight subjects had a higher cIMT than normal-weight subjects (0.63 vs. 0.54 mm, P<0.0001). Subjects with both systolic and diastolic hypertension had higher cIMT than those with isolated systolic hypertension (0.67 vs. 0.60, P<0.05). cIMT showed significant positive pairwise correlation with age, height, weight, BMI, and systolic blood pressure. Among all clinical variables analyzed, cIMT was most strongly correlated with BMI ( r=0.53, P<0.001). These results provide further evidence that vasculopathy occurs in association with known cardiovascular risk factors such as hypertension and obesity during childhood.

Obesity is associated with the development of hypertension but it is still not clear why hypertension is not observed in all obese patients. Obesity is a risk factor for the development of obstructive sleep apnea syndrome (OSAS) in children. OSAS has been linked to the development of hypertension in adults and children. The purpose of this study was to test the hypothesis that OSAS is one of the reasons that some obese children are hypertensive and some are not. The overnight polysomnography records of 90 patients (aged 4.2-18.8 years) were reviewed. BMI(score) [body mass index (BMI)/95th percentile BMI for age, sex, and race] was used to express the degree of obesity. The severity of systolic hypertension and diastolic hypertension were expressed as SBP(score) (systolic BP/the 95th percentile systolic BP for age, sex, and height) and DBP(score) (diastolic BP/the 95th percentile diastolic BP for age, sex, and height), respectively. OSAS was defined as more than one episodes of apnea per hour (AI) or an O(2) saturation associated with obstructive apnea of less than 90%. There were 56 obese patients; 42 were hypertensive and 40 patients were diagnosed with OSAS. The incidence of hypertension (68% vs. 30%) and obesity (75% vs. 52%) was higher in OSAS patients than those without OSAS. Compared with the non-obese patients, obese patients had a higher incidence of hypertension or OSAS, a higher BMI(score), SBP(score), DBP(score), AI, hypopnea index (HI), and apnea-hypopnea index (AHI). In obese patients, both SBP(score) and DBP(score) correlated positively with BMI(score), arousal index, and HI. DBP(score) also correlated positively with AHI. Multiple regression analysis showed that HI and BMI(score) were significant independent predictors of SBP(score) or DBP(score). Obese and hypertensive patients had a higher HI, AHI, and incidence of OSAS (64% vs. 29%) than the obese and normotensive patients. In conclusion, HI had a significant correlation with the degree of hypertension in obese patients, which could not be attributed to the degree of obesity. These findings are consistent with the hypothesis that OSAS is one of the reasons why some obese children are hypertensive and some are not.

Actual condition of alcohol intake was investigated in forty four thousand one hundred and twenty six individuals who visited the Tokai University Hospital Health Checkup Center from 1989 to 2003. Effects of alcohol intake were also examined in relation to several risk factors for lifestyle-related diseases. The male drinkers who took more than 1 gou of sake per a day were recognized in 53.0% from 1989 to 1991, and decreased to 46.3% from 2001 to 2003. The female drinkers were found in approximately 10%, and remained unchanged during the 15-year survey period. When examined by age, the frequency of habitual drinking among males was 34.4% in the age of 20 years, and then increased to 45% in the 30 years, leading to the peak (54.1%) in the 40 years. In females, the frequency was 27.5% in the age of 20 years, but decreased to 10.9% in the 30 years. The prevalence of systolic hypertension, diastolic hypertension, hyperuricemia, high levels of HbAlc, and hypertriglyceridemia was significantly (P < 0.0001) increased with an increase in alcohol intake. The prevalence of obesity, fatty liver and hyperglycemia at fasting was markedly (P < 0.0001) increased in the drinkers whose intake was more than 2 gou per a day. These findings indicate that habitual drinking may be associated with risk factors for lifestyle-related diseases, such as obesity, fatty liver, hypertension, hypertriglyceridemia and hyperuricemia.

A cross-sectional health examination survey was carried out among a random sample of 406 people of 30 years and above from a rural community to investigate the prevalence of coronary heart disease risk factors. Prevalence of smoking and tobacco use was 16%, alcohol intake 9.4 %, daily Salt intake (> or = 5 gram) 34.2%, daily saturated fat intake ( > or =10 % of daily energy intake) 47.0 % and physical inactivity 18.5 %. BMI was > or =25 Kg /m(2) in 18 percent and it was > or =30 Kg / m(2) in 3.2 percent population. Truncal obesity (WHR: men> 0.9; women > 0.8) was found 18.5 percent more in case of males (20.7). Abdominal obesity(men > or =102; women > or = 88)was found 15.7 percent more in case of males (20.6).18.5 percent population was found suffering from systolic hypertension> or =140 mm Hg )and 15 percent from diastolic hypertension(> or =90 mm Hg). Awareness of CHD risk factors was present in 30.0 percent population. Differences in prevalence of riskfactor in male and female were found statistically significant in case of smoking, alcohol consumption and abdominal obesity. The present study shows that prevalence of CHD risk factors increases significantly in men and women having BMI equal or more than 25 Kg /m(2) so this cutoff, should be used to determine obesity in Indian population.

We investigated in a young Italian obese population, the relationship between ambulatory BP (ABP) and several pathophysiological factors linking obesity to hypertension. A total of 89 obese children and adolescents underwent a 24-h ambulatory BP monitoring (ABPM) and an oral glucose tolerance test. The circulating levels of insulin, lipids, uric acid, C-reactive protein, interleukin-6, renin and aldosterone and the 24-h urinary levels of epinephrine, norepinephrine and albumin excretion rate were measured. Nine percent of subjects had daytime sustained hypertension (SH), 26% night-time hypertension and 11% a non-dipping pattern. SH subjects compared to those with sustained normotension (SN) were more obese (P<0.05), with a more frequent family history of hypertension (P<0.05), higher urinary catecholamine (P<0.05) and heart rate values (P<0.05) after adjustment for standard deviation score (SDS) of body mass index (BMI) and sex. Subjects with night-time hypertension compared to those with night-time normotension were more obese (P<0.0001), with a higher prevalence of impaired glucose tolerance (P<0.05) and metabolic syndrome (P<0.05) and higher 2-h glucose (P<0.05), uric acid (P<0.05) and triglycerides (P<0.05). In multivariate regression analysis, daytime systolic BP (SBP) remained independently correlated with urinary norepinephrine and SDS-BMI (P<0.05 for both), daytime diastolic BP (DBP) with waist circumference (P<0.05) and night-time SBP and DBP with SDS-BMI (P<0.01 for both). The risk of having systolic and diastolic hypertension increased with the increase in SDS-BMI and waist circumference, respectively. In conclusion, in our cohort of obese children and adolescents, daytime and night-time hypertension were associated with activation of the sympathoadrenal system and worst metabolic conditions, respectively.

The pathogenesis of diabetic nephropathy remains far from clear, partly due to the lack of a suitable animal model that mimics human renal disease in type 2 diabetes. In this study, the natural history of renal manifestations in ZSF1 rats, a recently developed rodent model of type 2 diabetes, is described. Male ZSF1 rats developed obesity and hyperglycemia by 20 weeks of age on a high-carbohydrate diet. They also developed systolic and diastolic hypertension, hypercholesterolemia, profound hypertriglyceridemia, proteinuria, and renal failure. Renal histology demonstrated changes consistent with early diabetic nephropathy, including arteriolar thickening, tubular dilation and atrophy, glomerular basement membrane thickening, and mesangial expansion. Furthermore, renal nitric oxide production was decreased, and homogenates from renal cortices demonstrated reduced expression of renal endothelial and inducible nitric oxide synthases. These changes were associated with increased urinary levels and renal expression of 8-hydroxydeoxyguanosine, an indicator of mitochondrial oxidative stress, as well as with increased renal peroxynitrite formation. Administration of either insulin or the antioxidant alpha-lipoic acid decreased proteinuria and oxidative stress, but only the former slowed progression of renal failure. We conclude that ZSF1 rats represent the best available rat model to study nephropathy from type 2 diabetes and that the renal lesions are associated with increased oxidative stress and decreased renal nitric oxide availability.

Obesity is related to office blood pressure (OBP). Important discrepancies exist between OBP and home blood pressure (HBP), providing complementary information for the management of hypertension. The association between obesity and HBP has not been investigated in children. The evidence on the role of obesity in the predominance of systolic blood pressure (SBP) over diastolic (DBP) in paediatric hypertension is limited. A total of 778 healthy subjects aged 6-18 years were recruited in this study. OBP and HBP were measured using electronic devices validated in children. Anthropometric measurements were measured and expressed as z-scores for height or age. Among all indices of obesity (z-scores), body mass index (BMI) showed the best association with BP. The effect of obesity (BMI) was more pronounced on: (i) SBP than DBP and (ii) H-SBP than O-SBP (O-SBP: r2=0.09, O-DBP: r2=0.05, H-SBP: r2=0.12, H-DBP: r2=0.06). The prevalence of systolic hypertension was higher than that of diastolic hypertension. This difference was significant only in office readings and independent from obesity (normal weight: 6.3% systolic hypertension versus 1.2% diastolic; obese: 37.9% versus 6.9%, P<0.05 for both). These data imply that in children and adolescents the z-score of BMI is the most appropriate index of the association between BP and obesity. It also suggests that obesity is probably more closely associated with home than office BP. Finally, although obesity appears to affect SBP more than DBP, these results suggest that the predominance of systolic hypertension in children and adolescents might not be only related to obesity but also to the measurement setting (office).
