ObjectiveThe present study examined the relationship between thyroid function status and the prevalence of metabolic syndrome in a Chinese population.MethodsCross-sectional data were obtained from the Thyroid Disease, Iodine Nutrition and Diabetes Epidemiology (TIDE) Survey. A total of 62,408 subjects aged ≥18 years were enrolled. Differences in metabolic indicators and the prevalence of metabolic syndrome according to sex and thyroid function status were compared. Logistic regression was used to analyze the influence of thyroid function on metabolic syndrome and its components.ResultsThe prevalence of metabolic syndrome was generally higher in men than women. Overt hyperthyroidism and subclinical hypothyroidism had a significant effect on metabolism in men. Body mass index (BMI), waist circumference, and triglycerides (TGs) were significantly lower in men in the overt hyperthyroidism group, and BMI, waist circumference, systolic blood pressure (SBP) and TGs were higher in men in the subclinical hypothyroidism group than men in the normal group. Overt and subclinical hypothyroidism had significant impacts on metabolic components in women. BMI, waist circumference, TGs, SBP and DBP in the subclinical and overt hypothyroidism groups were significantly higher than the euthyroid group in women. The relative risk of abdominal obesity and hypertriglyceridemia was increased in women with hypothyroidism. Thyroid dysfunction had different effects on metabolic syndrome and its components before and after menopause.ConclusionThyroid function had important effects on the prevalence of metabolic syndrome. Women with hypothyroidism, especially post-menopausal women, had a higher risk of metabolic syndrome than men.

Background. This study was conducted to assess the prevalence and clinical and epidemiological factors of thyroid dysfunction (TD) in Indian patients diagnosed with metabolic syndrome (MetS). Methods. In this cross-sectional study, 432 adults with an established diagnosis of MetS were enrolled across ten centers in India. Anthropometric measurements and vital signs were noted. Blood samples were tested for hemogram, coagulogram, lipid profile, and thyroid function. Fasting plasma glucose (FPG) and fasting plasma insulin were used for the calculation of homeostasis model assessment-estimated insulin resistance (HOMA-IR). Overt hypothyroidism was defined as thyroid-stimulating hormone TSH>4.50 μIU/mL with free thyroxine FT4<0.8 ng/dL and free triiodothyronine FT3<1.4 pg/mL; subclinical hypothyroidism as TSH>4.50 μIU/mL with FT4=0.8-1.8 ng/dL and FT3=1.4-4.4 pg/mL; overt hyperthyroidism as TSH<0.45 μIU/mL with FT4>1.8 ng/dL and FT3>4.4 pg/mL; and subclinical hyperthyroidism as TSH<0.45 μIU/mL with FT4=0.8-1.8 ng/dL and FT3=1.4-4.4 pg/mL. Results. About 121 out of 432 patients (28%) were diagnosed with TD (mean age±SD: 47.9±10.96 years), with women predominance (75% versus 25%). Most patients were in the >45 years of age group (men: 63%; women: 59%). TD was associated with high waist circumference (99.17%), reduced high-density lipoprotein-C (87.60%), raised HOMA-IR (86.78%), systolic blood pressure (77.69%), diastolic blood pressure (59.50%), fasting glucose (58.68%), and triglycerides (33.06%). Overt hypothyroidism was reported in 17.59% (N=76) of patients. Subclinical hypothyroidism, overt hypothyroidism, and subclinical hyperthyroidism were reported in 8.10%, 1.60%, and 0.70% patients with newly occurred TD, respectively. No case of overt hyperthyroidism was present in these patients. Conclusion. Hypothyroidism was the most common TD in Indian patients with MetS. A large proportion of TD cases diagnosed during the study highlight the need for vigilant thyroid screening in patients with MetS in a real-life setting.

Abstract Background: Inappropriate sleep duration (shorter/longer than optimal sleep duration) has come to be identified as a potential cardiometabolic risk factor, and thereby, as a risk factor for atherosclerotic cardiovascular disease (ASCVD). Few data exist regarding the gender differences in the relationship between sleep duration and cardiometabolic risk.Methods: This cross-sectional study was conducted in a study population of 9262 apparently healthy (5004 male, 4258 female) subjects at the Health Planning Center of Nihon University Hospital between September, 2015, and October 2016.Results: In the male subjects, as compared to a sleep duration of 6 to 7 hours, a sleep duration of ³8 hours was associated with an odds ratio (OR) for abdominal obesity (defined according to the Japanese criteria for metabolic syndrome as a waist circumference of ³85 cm) of 1.31 (95% confidence interval [CI], 1.004-1.71) and for a non-high-density lipoprotein cholesterol level of ³150 mg/dL (defined as “Borderline hyper” by the Japan Atherosclerosis Society Guidelines for Prevention of ASCVD 2017) of 1.33 (1.05-1.68), and a sleep duration of <5 hours was associated with an OR (95% CI) for a fasting blood glucose of ³100 mg/dL (defined as “high” by a specialized lifestyle checkup program for the detection of symptoms of metabolic syndrome in Japan) of 1.74 (1.25-2.42). On the other hand, in the female subjects, as compared to a sleep duration of 6 to 7 hours, a sleep duration of <5 hours was associated with an OR (95% CI) for abdominal obesity (waist circumference ³90 cm) of 1.98 (1.11-3.55) and for a hemoglobin A1c (HbA1c) level of ³5.6 % of 1.52 (1.10-2.10), whereas a sleep duration of ³8 hours was not associated with worsening of any of the examined cardiometabolic risk factors. Conclusions: There may be gender differences in the relationship between sleep duration and cardiometabolic risk. To further reduce the risk of ASCVD, it may be of particular importance to emphasize adequate sleep duration.Clinical Trial Registration: UMIN (http://www.umin.ac.jp/) Study ID:　 UMIN000037643 retrospectively registered on 9 August 2019

Background: Metabolic syndrome is a collection of factors which can increase the risk of heart disease, stroke and diabetes. Subclinical hypothyroidism is a state of mild thyroid failure. There are few factors which increase the risk for developing subclinical hypothyroidism such as female gender, advanced age and greater dietary iodine intake. Subclinical hypothyroidism as it is more common than overt hypothyroidism. Objectives were to study prevalence of subclinical hypothyroidism in patients of metabolic syndrome and its association with demographic and clinical parameters.Methods: This cross-sectional observational study was conducted on patients attending General Medicine OPD and in-patients admitted at Navodaya Medical College and Hospital, Raichur including 103 cases of metabolic syndrome. The data was analyzed using statistical package for the social sciences (SPSS) 24.0 version.Results: Prevalence of subclinical hypothyroidism in our study was 30.1%. Majority were from 41-50 years age group i.e., 9 (29%) and majority were females i.e., 17 (54.8%). We did not find any association between Subclinical hypothyroidism and gender (p>0.05). Prevalence of overweight in our study among SCH was 35.5% compared to 18.1% of normal patients. Elevated levels of TG were observed in 64 i.e., 62.1%, elevated TC 23.3%, elevated levels of LDL in 30.1% patients.Conclusions: Prevalence of subclinical hypothyroidism in our study was 30.1%. Majority were from 41-50 years age group i.e., 29% and majority were females i.e., 17 (54.8%). We did not find any association between subclinical hypothyroidism and body mass index (BMI) in our study.

INTRODUCTION: Hypothyroidism is a syndrome resulting from thyroid hormone deficiency. Metabolic syndrome (MetS) is a cluster of metabolic abnormalities is associated with increased risk for atherosclerotic cardiovascular disease (CVS) and type 2 diabetes mellitus. Thyroid hormones are major regulatory hormones that control the rate of metabolic function; thus, alteration in the levels of these hormones may be associated with MetS. The objective of our study was to find out the prevalence of MetS in subclinical and overt hypothyroidism. MATERIAL AND METHODS: A hospital-based cross sectional study was conducted at Universal College of Medical Sciences Teaching Hospital (UCMS-TH) Bhairahawa from March to September 2019. A total of 222 hypothyroid patients were enrolled in this study. MetS was diagnosed by National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATP III; 2005) revision criteria. The anthropometric indices were recorded. fT3, fT4  and TSH were measured by chemiluminescence immunoassay (CLIA) method and other biochemical parameters were estimated by colorimetric method. Data were analyzed by using SPSS 16.0. RESULTS: Patients were aged between 10 and 60 years, with a mean age of 38.89 years. The prevalence of MetS was 44.1% of which 80.6% were females. Furthermore, the prevalence of MetS was found to be 43.7% in subclinical hypothyroidism and 46.6% in overt hypothyroidism. CONCLUSION: The prevalence of MetS is high in both overt and subclinical hypothyroidism. Screening for MetS in patients with hypothyroidism can reduce the risk for CVD, as well as the mortality rate and mortality associated with it.

AbstractTo evaluate the association between thyroid echogenicity and heterogeneity seen on ultrasonography (US) and thyroid function in pediatric and adolescent populations with autoimmune diffuse thyroid diseases (AITD). From 2000 to 2020, we reviewed thyroid ultrasound (US) images and thyroid function statuses in 133 children and adolescent AITD patients. Our review of the images focused on decreased echogenicity and heterogeneity, which were classified into four grades. Among patients with overt hypothyroidism or overt hyperthyroidism, 94.2% (65/69) showed a US grade of 3 or 4. In patients with subclinical hyper/hypothyroidism or euthyroidism, 45.3% (29/64) showed grades 1 or 2. There were no overt hyper/hypothyroidism patients with US grade 1. When we compared US grades according to thyroid status, more severe thyroid dysfunction was significantly associated with higher US grade (p = 0.047). Thyroid stimulating hormone (TSH) level differed significantly according to US grades when we evaluated hyperthyroid (p = 0.035) and hypothyroid (p = 0.027) states independently. 11 patients showed both US grade and thyroid function status changes on follow-up US. In children and adolescent AITD patients, there was an association between decreased echogenicity and heterogeneity on US and thyroid dysfunction.

Background: Sub-clinical hypothyroidism (SCH), overt hypothyroidism and metabolic syndrome (MetS) are recognized risk factors for atherosclerotic cardiovascular disease and Type 2 diabetes mellitus (DM- II).Thyroid function affects MetS parameters including blood pressure (BP), fasting blood sugar (FBS), serum triglycerides (TG) and high density lipoprotein cholesterol (HDL-C). But the relationship between MetS and thyroid functions is yet to be identified clearly. The present study is to investigate the frequency of MetS in patients of SCH and overt hypothyroidism. Materials and Methods: A hospital based cross–sectional study was conducted at Swastik referral laboratory and research centre. In this study, 50 patients with overt hypothyroidism, 50 patients with SCH and 129 euthyroid controls were enrolled. National Cholesterol Education Program- Adult Treatment Panel III (NCEP-ATP III; 2005) revision criteria were used to diagnose metabolic syndrome. Thyroid function test (TFT: FT3, FT4 and TSH) was done by using chemiluminescence immunoassay (CLIA) and other tests by using a semi-auto analyzer. ANalysis Of VAriance (ANOVA) test was performed using SPSS (version 16.0). Result: There was a significant difference in the mean of the waist circumference (p=0.031), BP systolic (p=0.010), BP diastolic (p<0.001)), FBS (p=0.001), serum HDL-C (p=0.031) and serum TG (p=0.003) between control, subclinical and overt hypothyroidism group (p<0.001). Prevalence of MetS was 25.6 % in euthyroid controls whereas 44.0% in the SCH group and 62.0% in the overt hypothyroid group (p<0.001). Conclusion: Thyroid dysfunction may be responsible for the development of metabolic syndrome.

Abstract Context Anemia and thyroid dysfunction often co-occur, and both increase with age. Human data on relationships between thyroid disease and anemia are scarce. Objective To investigate the cross-sectional and longitudinal associations between clinical thyroid status and anemia. Design Individual participant data meta-analysis. Setting Sixteen cohorts participating in the Thyroid Studies Collaboration (n = 42,162). Main Outcome Measures Primary outcome measure was anemia (hemoglobin &lt;130 g/L in men and &lt;120 g/L in women). Results Cross-sectionally, participants with abnormal thyroid status had an increased risk of having anemia compared with euthyroid participants [overt hypothyroidism, pooled OR 1.84 (95% CI 1.35 to 2.50), subclinical hypothyroidism 1.21 (1.02 to 1.43), subclinical hyperthyroidism 1.27 (1.03 to 1.57), and overt hyperthyroidism 1.69 (1.00 to 2.87)]. Hemoglobin levels were lower in all groups compared with participants with euthyroidism. In the longitudinal analyses (n = 25,466 from 14 cohorts), the pooled hazard ratio for the risk of development of anemia was 1.38 (95% CI 0.86 to 2.20) for overt hypothyroidism, 1.18 (1.00 to 1.38) for subclinical hypothyroidism, 1.15 (0.94 to 1.42) for subclinical hyperthyroidism, and 1.47 (0.91 to 2.38) for overt hyperthyroidism. Sensitivity analyses excluding thyroid medication or high levels of C-reactive protein yielded similar results. No differences in mean annual change in hemoglobin levels were observed between the thyroid hormone status groups. Conclusion Higher odds of having anemia were observed in participants with both hypothyroid function and hyperthyroid function. In addition, reduced thyroid function at baseline showed a trend of increased risk of developing anemia during follow-up. It remains to be assessed in a randomized controlled trial whether treatment is effective in reducing anemia.

Iodine deficiency during childhood affects physical and mental development. Iodine deficiency or excess both can negatively impact thyroid function. We conducted this study to assess iodine nutrition and thyroid function in children with insufficient urinary iodine concentration. A community-based cross-sectional study was conducted among the selected schools of Udayapur district. Urinary iodine concentration (UIC) was measured in 1012 school children (6-14 years). Based on UIC data, 83 blood samples were collected to measure serum thyroglobulin (Tg), thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), and free thyroxine (fT4). UIC was measured by ammonium persulfate digestion method, and Tg, TSH, fT4, and fT3 were measured using ELISA kits. The median UIE was 236 µg/L, and 11.1% of the children had insufficient UIC. The mean fT3, fT4, and TSH in children with insufficient UIC were 2.55±0.43 pg/mL, 0.96±0.28 ng/dL, and 3.60±1.44 mIU/L respectively. Among children with low UIC levels, the median Tg was 17.5 ng/mL. Overt hypothyroidism was seen in 6%, and subclinical hypothyroidism in 3.6%. The children had sufficient iodine nutrition, and the frequency of thyroid dysfunction was low among the children with insufficient UIC.

The Relationship

The relationship between physical activity levels, salivary cortisol, and the metabolic syndrome (MetSyn) score was examined. Twenty-three girls (8.4 ± 0.9 years) had a fasting blood draw, waist circumference and blood pressure measured, and wore an ActiGraph accelerometer for 5 days. Saliva samples were collected to measure cortisol levels. Previously established cut points estimated the minutes spent in moderate, vigorous, and moderate-to-vigorous physical activity. A continuous MetSyn score was created from blood pressure, waist circumference, high-density-lipoprotein (HDL), triglyceride, and glucose values. Correlation analyses examined associations between physical activity, cortisol, the MetSyn score, and its related components. Regression analysis examined the relationship between cortisol, the MetSyn score, and its related components adjusting for physical activity, percent body fat, and sexual maturity. Vigorous physical activity was positively related with 30 min post waking cortisol values. The MetSyn score was not related with cortisol values after controlling for confounders. In contrast, HDL was negatively related with 30 min post waking cortisol. Triglyceride was positively related with 30 min post waking cortisol and area under the curve. The MetSyn score and many of its components were not related to cortisol salivary levels even after adjusting for physical activity, body fat percentage, and sexual maturity.
