Frontiers in endocrinology. 2021;:694681
Abstract
UNLABELLED Because of the limitation of body mass index (BMI) in distinguishing adipose mass from muscle, the tri-ponderal mass index (TMI) has been proposed as a new indicator for better assessing adiposity in children and adolescents. However, it remains unclear whether TMI performs better than BMI or other adiposity indices in predicting obesity status in childhood and obesity-related cardiovascular risk factors (CVRFs) in childhood or adulthood. We searched PubMed, Cochrane Library, and Web of Science for eligible publications until June 15, 2021. A total of 32 eligible studies were included in this systematic review. We found that TMI had a similar or better ability to predict body fat among children and adolescents than BMI. However, most of the included studies suggested that TMI was similar to BMI in identifying metabolic syndrome although TMI was suggested to be a useful tool when used in combination with other indicators (e.g., BMI and waist circumference). In addition, limited evidence showed that TMI did not perform better than BMI for identifying specific CVRFs, including insulin resistance, high blood pressure, dyslipidemia, and inflammation in children and adolescents, as well as CVRFs in adults.

Diagnosis of Diabetes Mellitus in Older Adults.
Reddy, SSK
Clinics in geriatric medicine. 2020;(3):379-384
Abstract
In the United States, 4 out of 10 adults with diabetes are ≥65 years of age. The older adult with diabetes is very likely to be asymptomatic and also at higher risk of vascular disease. New concerns include new diagnosis of diabetes for older adults admitted to hospital and older adults in long-term care facilities. The pathophysiology for increased incidence of diabetes in older adults is multifactorial, but dominant features are increased likelihood of metabolic syndrome, dysfunctional insulin secretion, and peripheral insulin resistance. Society in general benefits from more cost-effective care of older adults with diabetes.

Hypertriglyceridemic waist-to-height ratio phenotype: association with atherogenic lipid profile in Han adolescents.
Ma, CM, Liu, XL, Yin, FZ, Gao, GQ, Wang, R, Lu, Q
European journal of pediatrics. 2015;(9):1175-81
Abstract
UNLABELLED Hypertriglyceridemic waist (HW) phenotype was associated with an atherogenic lipid profile in adolescents. But unlike adults, the cutoffs of waist circumference are age- and gender-specific standards and are less feasible for non-professional use. The present study tested the hypothesis that simple variables, such as waist-to-height ratio (WHtR) and serum triacylglycerol (TG) concentrations, could be used as screening tools for the identification of adolescents characterized by atherogenic lipid profile. In 2006, anthropometric and biochemical measurements were assessed in a cross-sectional population-based study of 3136 Han adolescents, aged 13-17 years. The hypertriglyceridemic waist-to-height ratio (HWHtR) phenotype was defined as serum TG concentrations ≥1.47 mmol/L and WHtR ≥0.48 for boys and ≥0.46 for girls. Hypercholesterolemia (total cholesterol ≥5.18 mmol/L), high low-density lipoprotein cholesterol (LDL-C ≥3.37 mmol/L), low high-density lipoprotein cholesterol (HDL-C <1.03 mmol/L), and high non-HDL-C (≥3.76 mmol/L) were considered as atherogenic lipid profiles. After control for age and sex, adolescents with the HWHtR phenotype were more likely to have hypercholesterolemia (odds ratio (OR) = 7.8, 95 % confidence interval (CI) = 3.5-17.3, P < 0.001), high LDL-C (OR = 9.4, 95 % CI = 2.8-31.2, P < 0.001), low HDL-C (OR = 10.8, 95 % CI = 6.9-17.0, P < 0.001), and high non-HDL-C (OR = 22.9, 95 % CI = 10.0-52.2, P < 0.001) than those adolescents with normal WHtR and normal serum TG concentrations. CONCLUSION The present study demonstrates that HWHtR phenotype is a simple marker for identifying adolescents with atherogenic lipid profile. Compared with HW phenotype, HWHtR phenotype is a non-age-dependent index with higher applicability to screen for cardiovascular risk factors in adolescents. WHAT IS KNOWN • The hypertriglyceridemic waist phenotype is represented by the simultaneous presence of elevated serum triacylglycerol and increased waist circumference. Hypertriglyceridemic waist phenotype can identify adolescents with metabolic syndrome. But the cutoffs of waist circumference are age- and gender-specific standards and are less feasible for non-professional use. WHAT IS NEW • The present study demonstrates that hypertriglyceridemic waist-to-height ratio phenotype is a simple marker for identifying adolescents with atherogenic lipid profile. Compared with hypertriglyceridemic waist phenotype, hypertriglyceridemic waist-to-height ratio phenotype is a non-age-dependent index with higher applicability to screen for cardiovascular risk factors in adolescents.

Aguiar, EJ, Morgan, PJ, Collins, CE, Plotnikoff, RC, Callister, R
Diabetes research and clinical practice. 2015;(1):45-54
Abstract
AIMS: The primary aim was to describe characteristics of men identified at high-risk for Type 2 diabetes mellitus (T2DM) using the Australian diabetes risk assessment (AUSDRISK) tool. Secondary aims were to determine the prevalence of pre-diabetes and metabolic syndrome in these men. METHODS Men (n=209) completed the AUSDRISK tool, with 165 identified as high-risk for T2DM (score ≥ 12, maximum 38). Demographic, anthropometric, physiological and behavioural outcomes were assessed for 101 men. Comparisons (one-way ANOVA) among three AUSDRISK score groups (12-15, 16-19, ≥ 20) were performed (significance level, P<0.05). RESULTS Common risk factors (percentages) among high-risk men were waist circumference (>90 cm; 93%), age (>44 years; 79%), physical activity level (< 150 min wk(-1); 59%), family history of diabetes (39%) and previously high blood glucose levels (32%). Men with AUSDRISK scores ≥ 20 had higher (mean ± SD) HbA1C (6.0 ± 0.4% [42 ± 4.4 mmol.mol(-1)], P<0.001), FPG (5.3 ± 0.6 mmol.L(-1), P=0.001) and waist circumference (113.2 ± 9.8 cm, P=0.026) than men with scores of 12-15. Mean FPG for the sample was 5.0 ± 0.6 mmol.L(-1), whereas mean HbA1C was 5.8 ± 0.5% [40 ± 5.5 mmol.mol(-1)]. Pre-diabetes prevalence was 70% and metabolic syndrome prevalence was 62%. CONCLUSIONS The AUSDRISK tool identified men who were mostly older than 44, and had large waist circumferences and elevated HbA1C. These findings provide evidence supporting the usefulness of the AUSDRISK screening tool for T2DM screening in clinical and research settings.

Routine Screening and Consultation Facilitate Improvement of Metabolic Syndrome.
Yoon, NH, Yoo, S, Kim, H, Han, Y
Journal of Korean medical science. 2015;(8):1092-100
Abstract
This randomized controlled trial study aimed to investigate the effects of a lifestyle intervention on metabolic syndrome (MetS) among middle-aged Koreans. A total of 243 middle-aged Koreans with MetS were randomly assigned to either of 2 types of lifestyle intervention for MetS and followed for 12 months. Health examinations and interventions were implemented at 16 regional branch facilities of a Korean medical institution from 2010, following the NCEP-ATP III criteria and recommendations. Lifestyle intervention (LI) group (n = 137) participated in a 12-week multi-component intervention including individual counseling, group sessions, and self-help materials. Basic usual intervention (BI) group (n = 106) was provided with one-page health information sheet on MetS and MetS management at baseline. Prevalence of MetS and each of MetS components, except for low HDL-cholesterol, in both groups were significantly reduced and maintained after the intervention. Notably, prevalence of hypertension and abdominal obesity continued to improve during the follow-up period. Between-group differences in results were not found. Both interventions were effective when they were accompanied with repeated check-ups and notification of MetS status. It is recommended to design clear guidelines for the notification of MetS after MetS screening and to encourage checking MetS status periodically for effective MetS management (KCT 0000446).

Abstract
AIMS: Because blood-based screening to identify those with prediabetes to take part in Diabetes Prevention Program (DPP) translation efforts can be costly and time-consuming, non-invasive methods are needed. The aims of this paper are to evaluate the ability of the American Diabetes Association (ADA) risk test in identifying individuals with prediabetes, as well as the use of body composition measures for this purpose. In addition the utility of these alternate methods to ascertain the presence of the metabolic syndrome was assessed. METHODS Potential participants were recruited from a worksite and three community centers to take part in a DPP translation study. Participants completed onsite screening where anthropometric measures, fasting lipids and glucose, and hemoglobin A1c were assessed. Those with a BMI ≥24 kg/m(2) and prediabetes and/or the metabolic syndrome were eligible to participate. Non-invasive screening methods were evaluated for their ability to identify those with prediabetes and the metabolic syndrome based on clinically measured values. RESULTS All non-invasive methods were highly sensitive (68.9% to 98.5%) in the detection of prediabetes, but specificity was low (6.7% to 44.5%). None of the alternatives evaluated achieved acceptable discrimination levels in ROC analysis. Similar results were noted in identifying the metabolic syndrome. CONCLUSIONS The non-invasive methods evaluated in this study effectively identify participants with prediabetes, but would also allow for enrollment of a large number of individuals who do not have prediabetes. Deciding whether to use these alternatives, blood-based measures, or a combination of both will ultimately depend on the purpose of the program and the level of flexibility regarding participant eligibility.

The reliability of the National Cholesterol Education Program's Adult Treatment Panel III (NCEP/ATP III) and the International Diabetes Federation (IDF) definitions in diagnosing metabolic syndrome (MetS) among Gaza Strip Palestinians.
Sirdah, MM, Abu Ghali, AS, Al Laham, NA
Diabetes & metabolic syndrome. 2012;(1):4-8
Abstract
OBJECTIVES Metabolic syndrome (MetS) which is a multifaceted syndrome, has been demonstrated as a common precursor for developing cardiovascular diseases and/or type 2 diabetes mellitus. Different diagnostic definitions for MetS have been proposed and recommended. We set up to evaluate the reliabilities of the National Cholesterol Education Program's Adult Treatment Panel III (NCEP/ATP III) and the International Diabetes Federation (IDF) definitions in diagnosing MetS among Gaza Strip Palestinians. MATERIALS AND METHODS This cross sectional study involved a randomly selected two hundred and thirty apparently healthy adults from the Gaza Strip. Anthropometric measurements, blood pressure, fasting plasma glucose, lipid profile, and questionnaire interviews were performed. RESULTS The overall prevalence of MetS in our Gaza Strip cohort was 23.0% and 39.5% according to NCEP/ATP III and IDF definitions respectively (p<0.001). No significant differences were seen in the number of MetS components in individuals having MetS by either definition (mean 3.42 ± 0.63 vs 3.52 ± 0.69 respectively, p=0.865). Both IDF and NCEP/ATP III showed an increased prevalence of MetS with age, and body mass index (BMI), however they revealed different prevalence trends with sex. Except for BMI, there were no significant differences in the general and metabolic related characteristics between subjects with MetS of IDF and NCEP/ATP III definitions. CONCLUSIONS Independently of the definition used, MetS is highly prevalent in Gaza Strip population, with a steady increase in MetS prevalence through age and BMI. The IDF definition tends to give higher values for MetS prevalence, and therefore could be more appropriate for diagnosing MetS in Gaza Strip cohort.

Abstract
AIM: To identify which parameters could help to distinguish the "metabolically benign obesity", which is not accompanied by insulin resistance (IR) and early atherosclerosis. METHODS Eighty two of 124 overweight/obese females formed the study population, which was divided into two groups (52 and 30 subjects, respectively) with and without IR according to a HO meostatic Metabolic Assessment (HOMA) cut-off of 2, and were studied in a cross-sectional manner. The main outcome measures were waist circumference, serum uric acid, high-density lipoprotein-cholesterol and triglycerides, alanine aminotransferase, blood pressure and the two imaging parameters, hepatic steatosis and longitudinal diameter of the spleen, which were measured in relation to the presence/absence of IR. RESULTS A variable grade of visceral obesity was observed in all subjects with the exception of three. Obesity of a severe grade was represented more in the group of IR individuals (P = 0.01). Hepatic steatosis, revealed at ultrasound, was more pronounced in IR than in non-IR subjects (P = 0.005). The two groups also demonstrated a clear difference in longitudinal spleen diameter and blood pressure, with raised and significant values in the IR group. Metabolic syndrome was frequent in the IR group, and was not modified when adjusted for menopause (P = 0.001). At linear regression, the beta values of waist circumference and body mass index predicting HOMA were 0.295, P = 0.007 and 0.41, P = 0.0001, respectively. Measures of spleen longitudinal diameter were well predicted by body mass index (BMI) values, beta = 0.35, P = 0.01, and by HOMA, beta = 0.41, P = 0.0001. Blood pressure was predicted by HOMA values, beta = 0.39, P = 0.0001). HOMA and hepatic steatosis were highly associated (rho = 0.34, P = 0.002). Interestingly, IR patients were almost twice as likely to have hepatic steatosis as non-IR patients. Among the MS criteria, blood pressure was very accurate in identifying the presence of IR (AUROC for systolic blood pressure 0.66, cut-off 125 mm of Hg, sensibility 64%, specificity 75%; AUROC for diastolic blood pressure 0.70, cut-off 85 mm of Hg, sensibility 54.5%, specificity 75%). CONCLUSION As health care costs are skyrocketing, reliable and mainly inexpensive tools are advisable to better define subjects who really need to lose weight.

Wiener klinische Wochenschrift. 2009;(5-6):202-8
Abstract
OBJECTIVE Our aim was to evaluate the usefulness of screening for cardiovascular risk factors and the effect of applying professional guidelines for risk reduction in postmenopausal women, as judged by the Framingham and the high-risk systematic coronary risk evaluation (SCORE) methods. METHODS 18 menopause clinics in Hungary participated in the study, enrolling a total of 2789 patients. Physicians were asked to follow professional guidelines for the primary prevention of cardiovascular disease. Patients were requested to attend follow-up every four months for 12 months. RESULTS The mean age of the patients was 56.7+/-6.9 years, and the time elapsed since the last menstrual period was 9.2+/-7.2 years. Overall, 29.4% of patients attended at least one follow-up visit. At the initial visit, high total cholesterol level (>5 mmol/l) was detected in 78% of patients, high triglyceride level (>1.7 mmol/l) in 29%, high systolic and/or diastolic blood pressure (>140/90 mmHg) in 32%, fasting plasma glucose level>6.1 mmol/l in 15%. Increased waist circumference (>88 cm) was found in 85.8% of the patients; 18.3% of the patients smoked, which did not change. After 12 months, all laboratory parameters and the blood pressure had improved significantly. Both the Framingham and SCORE systems showed a significant improvement in the cardiovascular risk status, and the rate of metabolic syndrome had decreased significantly by the end of the study. CONCLUSIONS Screening postmenopausal women for cardiovascular risk and the application of professional guidelines for primary prevention may significantly reduce the risk of coronary artery disease in this group. Patient compliance with follow-up visits needs improvement.

Evaluating obesity and cardiovascular risk factors in children and adolescents.
Spiotta, RT, Luma, GB
American family physician. 2008;(9):1052-8
Abstract
Obesity continues to be a growing public health problem. According to the 2003-2004 National Health and Nutrition Examination Survey, 17 percent of persons two to 19 years of age are overweight. The number of obese children and adolescents has tripled in the past 20 years. Obesity in adults is associated with cardiovascular risk factors including hypertension, dyslipidemia, and diabetes. The growing prevalence of overweight in children and adolescents is paralleled by the growth of its associated complications in that population: hypertension, diabetes, hyperlipidemia, and metabolic syndrome. A modification of the metabolic syndrome criteria designed for children and adolescents shows that as many as 50 percent of those who are severely overweight have the syndrome. The U.S. Preventive Services Task Force has not found sufficient evidence to support screening children for obesity or other cardiovascular risk factors. The American Academy of Pediatrics and the American Heart Association have adopted a more aggressive stance, based largely on consensus opinion. Current suggestions include focusing on children whose body mass indexes exceed the 85th percentile; who are rapidly gaining weight; who have a family history of type 2 diabetes or hypercholesterolemia; or who have hypertension or signs of insulin resistance. Physician advocacy for healthy communities and institutions that foster physical activity, good eating habits, and healthy lifestyles is also encouraged.
