ObjectivesAbdominal fat has been identified as a risk marker of cardiometabolic disease independent of overall adiposity. However, it is not clear whether there are ethnic disparities in this risk. We investigated the associations of visceral adipose tissue (VAT) and abdominal subcutaneous adipose tissue (SAT) with cardiometabolic risk factors in three ethnic diverse populations of Inuit, Africans and Europeans.DesignCross-sectional pooled study.SettingGreenland, Kenya and Denmark.MethodsA total of 5113 participants (2933 Inuit, 1397 Africans and 783 Europeans) from three studies in Greenland, Kenya and Denmark were included. Measurements included abdominal fat distribution assessed by ultrasound, oral glucose tolerance test, hepatic insulin resistance, blood pressure and lipids. The associations were analysed using multiple linear regressions.ResultsAcross ethnic group and gender, an increase in VAT of 1 SD was associated with higher levels of hepatic insulin resistance (ranging from 14% to 28%), triglycerides (8% to 16%) and lower high-density lipoprotein cholesterol (HDL-C, −1.0 to −0.05 mmol/L) independent of body mass index. VAT showed positive associations with most of the other cardiometabolic risk factors in Inuit and Europeans, but not in Africans. In contrast, SAT was mainly associated with the outcomes in Inuit and Africans. Of notice was that higher SAT was associated with higher HDL-C in African men (0.11 mmol/L, 95% CI: 0.03 to 0.18) and with lower HDL-C in Inuit (−0.07 mmol/L, 95% CI: -0.12 to –0.02), but not in European men (−0.02 mmol/L, 95% CI: −0.09 to 0.05). Generally weaker associations were observed for women. Furthermore, the absolute levels of several of the cardiometabolic outcomes differed between the ethnic groups.ConclusionsVAT and SAT were associated with several of the cardiometabolic risk factors beyond overall adiposity. Some of these associations were specific to ethnicity, suggesting that ethnicity plays a role in the pathway from abdominal fat to selected cardiometabolic risk factors.

Background:The purpose of this study was to evaluate the relationship between adherence to pediatric 24-hour movement guidelines (moderate to vigorous physical activity, sedentary behavior, and sleep) and cardiometabolic risk factors.Methods:The sample included 357 white and African American children aged 5–18 years. Physical activity, television viewing, and sleep duration were measured using questionnaires, and the 24-hour movement guidelines were defined as ≥60 minutes per day of moderate to vigorous physical activity on ≥5 days per week, ≤ 2 hours per day of television, and sleeping 9–11 hours per night (ages 5–13 y) or 8–10 hours per night (ages 14–18 y). Waist circumference, body fat, abdominal visceral and subcutaneous adipose tissue, blood pressure, fasting triglycerides, high-density lipoprotein cholesterol, and glucose were measured in a clinical setting.Results:A total of 26.9% of the sample met none of the guidelines, whereas 36.4%, 28.3%, and 8.4% of the sample met 1, 2, or all 3 guidelines, respectively. There were significant associations between the number of guidelines met and body mass index, visceral and subcutaneous adipose tissue, triglycerides, and glucose. There were no associations with blood pressure or high-density lipoprotein cholesterol.Conclusions:Meeting more components of the 24-hour movement guidelines was associated with lower levels of obesity and several cardiometabolic risk factors. Future efforts should consider novel strategies to simultaneously improve physical activity, sedentary time, and sleep in children.

Context: Thyroid hormones play an important role in the metabolic homeostasis of the body and have been associated with cardiometabolic risk. Objective: To examine the association of cardiometabolic risk factors (CMRF) with TSH levels in youth at population level in the US. Design & Setting: Cross-sectional study of youth aged 12-18 years without known thyroid abnormalities from National Health and Nutrition Examination Survey 1999-2012. Subclinical hypothyroidism (SH) was defined as TSH levels 4.5-10 mIU/L. Assessed CMRF included abdominal obesity (waist circumference > 90th percentile), hypertriglyceridemia (TG ≥ 130 mg/dL), low HDL cholesterol (HDL-C < 40 mg/dL), elevated blood pressure (SBP and DBP ≥ 90th percentile), hyperglycemia (FBG ≥ 100 mg/dL, or known diabetes), insulin resistance (HOMA-IR > 3.16) and elevated alanine transferase (ALT ≥ 50 U/L for boys and ≥ 44 U/L for girls). Age and sex- specific percentiles for thyroid parameters were calculated for youth with normal weight. Results: In this cohort of youth (51.3% male), 31.2% had overweight/obesity. The prevalence of SH was 2.0 % (95% CI 1.2-3.1). The median TSH levels were higher in youth with overweight/obesity (p<.001). Adjusting for age, sex, race/ethnicity and level of obesity, youth with TSH in the 4th quantile had higher odds of abdominal obesity (OR 2.53 [1.43-4.46], p = .002), higher HOMA-IR (OR 2.82 [1.42-5.57], p=.003) and ≥ 2 CMRF (OR 2.20 [1.23-3.95], p=.009). Conclusions: The prevalence of SH is low in US youth. The higher odds of insulin resistance and CMRF in youth with TSH levels > 75th percentile requires further study.

OBJECTIVE: To investigate the relationship between ultrasensitive C-reactive protein and cardiometabolic risk factors in overweight or obese childrenand adolescents. METHODS: Cross-sectional study conducted at the Center for Childhood Obesity in the period from April 2009 to April 2010, involving 185 overweight children and adolescents aged 2 to 18 years. Measures of ultrasensitive C-reactive protein according to age, nutritional status, gender, race, cardiometabolic risk factors (waist circumference, lipid profile, impaired fasting glucose, high blood pressure and presence of insulin resistance) were compared through the Chi-square test and analysis of variance. All analyses were performed using the Statistical Package for the Social Sciences software version 17.0, adopting a significance level of 5%. RESULTS: Altered high-density lipoprotein was the most frequent cardiometabolic risk factor, and there was a significant association between altered ultrasensitive C-reactive protein values and severe obesity (p=0.005), high waist circumference (p<0.001), hypertriglyceridemia (p=0.037) and insulin resistance (p=0.002), as well as significantly higher body mass index (p=0.000), waist circumference (p=0.001), insulin (p=0.005) and index of glucose homeostasis values(p=0.005). CONCLUSION: High prevalence of altered ultrasensitive C-reactive protein and significant association with severe obesity, waist circumference, hypertriglyceridemia and insulin resistance were observed.

Abstract Context Thyroid hormones play an important role in the metabolic homeostasis and higher levels have been associated with cardiometabolic risk. Objective To examine the association of cardiometabolic risk factors with TSH levels in US youth. Design & Setting Cross-sectional study of youth aged 12-18 years without known thyroid abnormalities from five National Health and Nutrition Examination Survey cycles (n=2,818) representing 15.4 million US children. Subclinical hypothyroidism (SH) was defined as TSH levels 4.5-10 mIU/L. Assessed cardiometabolic risk factors include abdominal obesity (waist circumference &gt; 90 th percentile), hypertriglyceridemia (TG ≥130 mg/dL), low HDL cholesterol (HDL-C &lt; 40 mg/dL), elevated blood pressure (SBP and DBP ≥90 th percentile), hyperglycemia (FBG ≥100 mg/dL, or known diabetes), insulin resistance (HOMA-IR &gt; 3.16) and elevated alanine transferase (ALT ≥ 50 U/L for boys and ≥ 44 U/L for girls). Age and sex- specific percentiles for thyroid parameters were calculated. Results In this cohort of youth (51.3% male), 31.2% had overweight/obesity. The prevalence of SH was 2.0 % (95% CI 1.2-3.1). The median TSH levels were higher in youth with overweight/obesity (p&lt;.001). Adjusting for age, sex, race/ethnicity and obesity, youth with TSH in the 4 th quantile had higher odds of abdominal obesity (OR 2.53 [1.43-4.46], p = .002), insulin resistance (OR 2.82 [1.42-5.57], p=.003) and ≥ 2 CMRF (OR 2.20 [1.23-3.95], p=.009). Conclusions The prevalence of SH is low in US youth. The higher odds of insulin resistance and cardiometabolic risk factors in youth with TSH levels &gt; 75 th percentile requires further study.

ObjectiveTo investigate the association of abdominal visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) with cardiometabolic risk factors in children and adolescents.Research design and methodsThis cross-sectional study consisted of 8460 children and adolescents aged 6–18 years from Chinese urban areas who underwent dual-energy X-ray absorptiometry scan and had metabolic risk factors measured.ResultsIn multivariate analysis adjusted for region, family income, age, puberty development, physical activity, and smoking, VAT and SAT were significantly associated with all metabolic risk factors for both sexes (all p<0.01). After additional adjustment for fat mass index, most of these associations remain significantly positive. In boys, SAT had greater ORs for all risk factors compared with VAT; in girls, however, SAT had greater odds for high triglycerides, smaller odds for high low-density lipid cholesterol, and similar odds for other risk factors compared with VAT. In addition, boys had greater magnitude of associations of SAT with high total cholesterol, high low-density lipid cholesterol, and low high-density lipid cholesterol compared with girls; no sex differences for VAT were observed.ConclusionsBoth abdominal VAT and SAT have adverse impacts on most of the cardiometabolic risk factors in youth. However, their relative contributions differ between sexes.

Abstract Background The burden of insulin resistance (IR) among young American adults has not been previously assessed. We evaluated the 1) prevalence and trends of IR and cardiometabolic risk factors and, 2) assessed the association between measures of adiposity and IR among adults aged 18-44 years without diabetes and preexisting cardiovascular disease. Methods Cross-sectional survey data from six consecutive National Health and Nutrition Examination Survey (2007-2008 to 2017-2018) cycles were analyzed. IR was defined by the homeostatic model assessment for IR (HOMA-IR) of ≥2.5. The temporal trends of IR, cardiometabolic risk factors, and the relationship between IR and measures of adiposity were assessed using multivariable-adjusted regression models. Results Among 6,247 young adults aged 18-44 years, the prevalence of IR was 44.8% (95% CI: 42.0-47.6%) in 2007-2010 and 40.3% (95% CI: 36.4-44.2%) in 2015-2018 (Ptrend=0.07). There was a modest association of HOMA-IR with higher body mass index (BMI), waist circumference, total lean fat mass, and total and localized fat mass (all p&lt;0.001). Participants with IR had a higher prevalence of hypertension (31.3% [95% CI: 29.2-33.5%] vs. 14.7% [95% CI: 13.2-16.2%]), hypercholesterolemia (16.0% [95% CI: 12.4-19.5%] vs. 7.0% [95% CI: 5.8-8.5%]), obesity (56.6% [95% CI: 53.9-59.3%] vs. 14.7% [95%CI: 13.0-16.5%]) and poor physical activity levels (18.3% [95% CI: 16.4-20.2%] vs. 11.7% [95%CI: 10.3-13.1%]) compared to participants without IR (all p&lt;0.05). Conclusions Four-in-ten young American adults have IR, which occurs in a cluster with cardiometabolic risk factors. Nearly half of young adults with IR are non-obese. Screening efforts for IR irrespective of BMI may be required.
