Background: The contribution of adiposity and metabolic syndrome (MetS) to thyroid cancer risk in late life, particularly among the elderly, is unclear. Methods: We conducted a nationwide cohort study of Korean adults aged ≥75 years who underwent standardized health screening. Exposures were body mass index (BMI), waist circumference (WC), and MetS defined by standard clinical criteria. The incidence of thyroid cancer was determined using administrative data. Fine–Gray sub-distribution hazard models estimated adjusted hazard ratios (HRs) with prespecified stratification by sex and age (75–84 vs. ≥85 years). Results: Among 1,164,707 participants (60.3% women), 2645 incident cases were identified. In the fully adjusted models, obesity (BMI ≥ 25 kg/m2) was associated with a 37% higher hazard (HR, 1.37; 95% confidence interval [CI], 1.27–1.49) and MetS with an 18% higher hazard (HR, 1.18; 95% CI, 1.09–1.28). In sex-stratified models, MetS was associated with thyroid cancer in women (HR 1.19; 95% CI, 1.08–1.31) and showed a similar direction of association in men (HR 1.16; 95% CI, 1.00–1.35), with overlapping CIs. By age, associations were evident at 75–84 years (MetS: HR, 1.18; obesity: HR, 1.36), whereas at ≥85 years, only obesity remained significant (HR, 1.90; 95% CI, 1.13–3.18). Among MetS components, high WC showed the most consistent association (HR, 1.31; 95% CI, 1.21–1.42). Conclusions: In adults aged ≥75 years, general obesity and, in particular, central adiposity are robustly associated with incident thyroid cancer, whereas metabolic syndrome confers a more modest and mainly age- and sex-specific additional risk.

Background and Objectives: Cardiometabolic diseases are rising in Latin America, yet rural Amazonian populations remain understudied. We aimed to characterize the prevalence and factors associated with a simple composite cardiometabolic risk in rural Amazonian adults. Materials and Methods: We conducted an analytical cross-sectional study during community screenings in San Martín, Peru, in 2025, enrolling adults aged ≥ 18 years. The outcome was present when ≥2 biological/anthropometric alterations were identified at the same visit (hypertension, dyslipidemia, hyperglycemia, hyperuricemia, general obesity, abdominal obesity, or elevated waist-to-hip ratio). Behaviors included current tobacco use, alcohol risk (AUDIT), and physical activity (IPAQ). We summarized variables (univariate), compared groups (bivariate: chi-square; Fisher for alcohol), and fitted modified Poisson regression with robust errors to estimate prevalence ratios (PRs); variables with p ≤ 0.20 in bivariate analysis entered multivariable models. Results: We enrolled 205 adults; 70.2% met the composite outcome. In multivariable models, abdominal obesity (adjusted PR [aPR] 1.70; 95% CI 1.40–2.10), hyperglycemia (1.65; 1.25–2.17), hyperuricemia (1.38; 1.19–1.61), dyslipidemia (1.25; 1.07–1.46), and general obesity (1.21; 1.04–1.40) were independently associated with cardiometabolic risk. Hypertension (1.06; 0.88–1.29) and elevated waist-to-hip ratio (1.20; 0.88–1.63) were not. Physical activity differed crudely but showed no independent association; tobacco and alcohol were not associated. Conclusions: In this rural Amazonian population, we observed a high prevalence of composite cardiometabolic risk and found that central adiposity and metabolic derangements, not blood pressure or self-reported behaviors, were the main correlates. Simple measures such as waist circumference, fasting glucose or HbA1c, a basic lipid panel, and serum urate may help flag adults at higher cardiometabolic risk in similar low-resource primary-care settings, but prospective studies are needed to evaluate their predictive value and screening performance.

Background and Objectives: As the demand for dietitian services continues to grow in high-volume healthcare settings, optimizing both the frequency and modality of follow-up has become crucial for sustaining and enhancing the effectiveness of medical nutrition therapy (MNT). This study evaluated a stepwise intensification model ranging from quarterly in-person visits to monthly in-person visits and weekly telehealth follow-ups in metabolic syndrome (MetS). Materials and Methods: Ninety-three patients with MetS were randomized into three groups based on the intensity of dietary consultations: the intervention group (IG, n = 31), the intensive intervention group (IIG, n = 30), and the control group (CG, n = 32). IG received four in-person visits (baseline and weeks 4, 8, and 12); IIG received the same four visits plus weekly telehealth calls; and CG received two at baseline and week 12. Nutrient intake, anthropometric and biochemical measurements were compared across groups. A regression model was applied to examine associations between the frequency of nutritional counseling and MetS components. Results: Higher counseling frequency was associated with greater improvements in dietary intake, anthropometric, biochemical and blood pressure parameters. Both intervention groups achieved greater reductions in waist circumference (p < 0.001), BMI (p < 0.001), and body weight (p = 0.002) than CG, with the IIG improvements in FPG (p < 0.001, η2 = 0.215) and blood pressure benefits (systolic: p < 0.001, η2 = 0.276; diastolic: p < 0.001, η2 = 0.148). In multivariable regression, counseling frequency independently predicted improvement in MetS diagnostic criteria (F = 9.395; p < 0.001, adjusted R2 = 0.313). Conclusions: These findings highlight that integrating telehealth into MNT for MetS may enhance its effectiveness while minimizing the burden on healthcare systems. Full article

Background/Objectives: This study investigated the association between physical activity (PA) levels and the risk of chronic diseases in Korean adults with sleep deficiency (SD). Methods: Data were obtained from the Korea National Health and Nutrition Examination Survey (2016–2021; n = 31,338). SD was defined as less than 7 h of sleep per night. The PA levels were categorized as low, moderate, or high. Multivariable logistic regression was used to estimate odds ratios (OR) with 95% confidence intervals (CI) for various chronic diseases, adjusting for demographic and lifestyle covariates. Results: High PA levels were associated with lower odds of abdominal obesity (OR = 0.855, 95% CI = 0.782–0.934, p < 0.001), hypertension (OR = 0.787, 95% CI = 0.657–0.942, p < 0.01), diabetes mellitus (OR = 0.743, 95% CI = 0.622–0.887, p < 0.01), and metabolic syndrome (OR = 0.706, 95% CI = 0.586–0.850, p < 0.001). Moderate PA showed similar but weaker associations. Conversely, high PA levels were associated with higher odds of depression (OR = 1.474, 95% CI = 1.123–1.935, p < 0.01). Subgroup analyses indicated that the protective effects of PA were stronger among women, non-smokers, and individuals with obesity. Conclusions: Among adults with SD, moderate-to-vigorous PA is associated with a lower odds of several metabolic disorders, including abdominal obesity, diabetes, and metabolic syndrome. This highlights the importance of regular PA in maintaining metabolic health. However, a positive association between high PA and depression should warrant further investigation, as reverse causality or residual confounding may explain this association. Full article

Background: Metabolic Syndrome (MetS) is a multifactorial condition characterized by insulin resistance, dyslipidemia, hypertension, and abdominal obesity, which collectively increase the risk of type 2 diabetes mellitus and cardiovascular diseases. Lifestyle modification represents the first-line strategy in its management, whereas pharmacological interventions are complex and typically require long-term polypharmacotherapy. In this context, natural bioactive compounds with pleiotropic effects are gaining increasing attention. Among these, S-allyl cysteine (SAC), the major sulfur-containing compound derived from black garlic, has been identified as a promising candidate due to its well-documented antioxidant and anti-inflammatory properties. Methods: This narrative review examines the pathophysiological mechanisms underlying MetS and summarizes current evidence on the protective role of SAC against key pathological features of this condition, including oxidative stress, inflammation, glucose and lipid dysmetabolism, endothelial dysfunction, and gut microbiota alterations. Results: Preclinical studies indicate that SAC counteracts lipid accumulation, insulin resistance, endothelial dysfunction, and gut dysbiosis through multiple mechanisms, including hydrogen sulfide release, reactive oxygen species scavenging, inhibition of advanced glycation end products, and modulation of metabolic pathways. Conclusions: SAC emerges as a promising nutraceutical for the prevention and management of MetS and its complications. This underscores the broader relevance of nutraceuticals as promising tools in mitigating metabolic dysfunctions and reducing the burden of cardiometabolic diseases. Full article

This review examines the intricate relationship between obesity and venous thromboembolism (VTE), highlighting the underlying pathophysiological mechanisms and clinical implications. Obesity is an established independent risk factor for VTE, which includes deep vein thrombosis (DVT) and pulmonary embolism (PE). The risk of VTE escalates with increasing body mass index (BMI) and is particularly associated with abdominal adiposity. Dysfunctional adipose tissue (AT) in obesity promotes a pro-thrombotic state through chronic low-grade inflammation and impaired fibrinolysis. This inflammation is driven by stress within hypertrophied adipocytes, which leads to localized hypoxia, cellular dysfunction, and ultimately, cell death. This inflammation is driven by adipocyte stress and the infiltration of immune cells. The adipokine leptin exemplifies the complex link between obesity and VTE. While leptin has pro-thrombotic effects, low leptin levels are paradoxically associated with an increased morbidity and mortality in patients with acute PE, a phenomenon termed the “obesity paradox”. Furthermore, metabolic syndrome significantly increases the risk of recurrent VTE, with the risk growing with each additional metabolic component. Ultimately, a deeper understanding of the molecular and cellular links between obesity and VTE is essential for developing targeted strategies to reduce risk and improve outcomes in this vulnerable population.

Background/Objectives: Dietary fibers from cereals promote the production of short-chain fatty acids (SCFA), which have been linked to improved glucose and lipid metabolism, reduced inflammation, and decreased oxidative stress. Wheat aleurone, a bran fraction enriched in fermentable fibers and bioactive compounds, may enhance SCFA production, but clinical evidence remains limited. This study investigated whether a wheat aleurone-rich diet, compared with a refined wheat diet, modulates circulating SCFA concentrations and their relationship with oxidative stress in individuals at elevated cardio-metabolic risk. Methods: In a randomized, cross-over trial, 23 adults with abdominal obesity and at least one additional metabolic syndrome feature consumed isoenergetic diets enriched with wheat aleurone or refined wheat for 8 weeks. Fasting and postprandial serum SCFA concentrations were measured over 3 h following standardized test meals using the gas chromatography method. Urinary 8-isoprostane excretion was assessed as a biomarker of oxidative stress using the ELISA method. SCFA values are reported as changes (increase/decrease) from fasting values, calculated by subtracting the fasting value from that of each time point. Results: Compared with refined wheat, the wheat aleurone diet significantly increased postprandial butyrate response (p = 0.005, time × meal interaction), with higher values observed at 150 min (p = 0.027) and 180 min (p = 0.001). The mean change in postprandial butyrate was also greater after the wheat aleurone diet (+0.95 ± 1.92 vs. −0.32 ± 2.01 µmol/L; p = 0.040). Importantly, butyrate at 180 min was inversely correlated with urinary 8-isoprostane (r = −0.618, p = 0.019). No significant differences were found for acetate or propionate. Conclusions: A wheat aleurone-rich diet enhances postprandial butyrate production and is associated with lower oxidative stress, suggesting a role of butyrate in mediating the antioxidant benefits of wheat aleurone in individuals with cardio-metabolic risk.

Objective: Metabolic syndrome (MetS) represents a growing and significant public health burden worldwide. The evidence regarding whether skipping breakfast affects the development of MetS and its components remains inconsistent and uncertain. This study aimed to synthesize the best available evidence regarding the association between skipping breakfast and the risk of MetS and its components. Methods: This systematic review and meta-analysis was conducted in accordance with the PRISMA 2020 guidelines. We systematically searched the PubMed, Embase, Cochrane Library, and Web of Science databases from inception until May 2025. Two reviewers independently screened titles/abstracts and full texts, extracted data, and assessed the risk of bias. This review included cross-sectional and cohort studies on the association between breakfast skipping and the risk of MetS and its components. Results: Nine studies were included after quality evaluation by NOS. Pooled results from the meta-analysis revealed that skipping breakfast was significantly associated with an increased risk of MetS (OR: 1.10, 95% CI: 1.04–1.17) and its components—namely abdominal obesity (OR = 1.17, 95% CI 1.01–1.34), hypertension (OR: 1.21, 95% CI: 1.10–1.32), hyperlipidemia (OR: 1.13, 95% CI: 1.04–1.23), and hyperglycemia (OR = 1.26, 95% CI: 1.16–1.37). Conclusions: The meta-analysis demonstrated that skipping breakfast was significantly associated with an increased risk of MetS and its key components—abdominal obesity, hypertension, hyperlipidemia, and hyperglycemia. These findings highlight regular breakfast consumption as a potential modifiable factor for preventing and managing MetS and related cardiometabolic diseases. Full article

Metabolic syndrome (MetS) is a multifactorial clinical condition characterized by the co-occurrence of abdominal obesity, impaired glucose metabolism, high blood pressure, and dyslipidemia. Non-pharmacological strategies, such as hypocaloric diets (HD) and structured physical training (PT), have shown promise in improving metabolic and functional outcomes in this population. The aim of this prospective interventional study was to evaluate the effects of a 16-week program combining HD with PT on ventilatory efficiency and cardiometabolic risk markers in women with MetS. Forty-one sedentary women (aged 45–55 years) with clinically diagnosed MetS underwent anthropometric, metabolic, nutritional, and cardiopulmonary assessments before and after the intervention. Participants engaged in 60 min exercise sessions three times per week and followed a personalized hypocaloric diet targeting 5–10% weight loss. Post-intervention analyses revealed significant reductions (p ≤ 0.05) in body weight (from 86.6 kg ± 3.3 kg to 78.2 kg ± 3.3 kg), body fat percentage (40.1% ± 0.6% to 33.4% ± 1.6%), and waist circumference (105.1 cm ± 1.2 cm to 95.7 cm ± 1.9 cm). Improvements were also observed in fasting glucose (from 117.1 mg/dL to 95.1 mg/dL) and triglycerides (158.8 mg/dL ± 9.1 mg/dL to 111.8 mg/dL ± 9.1 mg/dL), and in lean mass percentage (59.9% ± 6.5% to 66.6% ± 1.7%). Cardiopulmonary variables showed enhanced ventilatory function, with increased VO2peak (1.59 L/min ± 0.1 L/min to 1.74 ± 0.1 L/min), improved oxygen uptake efficiency slope (OUES), and a steeper VO2/workload relationship. Resting heart rate and blood pressure declined significantly (69.9 bpm ± 2.0 bpm to 64.9 ± 1.8 bpm; 145.4 mmHg ± 3.9/80.2 ± 3.0 mmHg to 140.1 mmHg ± 2.7/75.2 ± 1.6 mmHg). In conclusion, the 16-week intervention combining HD with PT proved effective for reducing cardiometabolic risk factors and enhancing ventilatory efficiency, suggesting improved integration of oxygen uptake, transport, and utilization in the women with MetS assessed.

Background/Objectives: Spinal epidural lipomatosis (SEL) is increasingly recognized as a possible radiological indicator of Metabolic Syndrome (MS) and visceral adiposity. However, the precise relationship between visceral adiposity and the accumulation of epidural fat (EF) remains unclear. This study aimed to investigate the association between visceral adipose tissue (VAT) and EF thickness using quantitative MRI analyses. Methods: We retrospectively reviewed all MRI scans performed at our institution over a 7-month period, from May to November 2024. Two radiologists measured and recorded the VAT maximum antero-posterior diameter at the L3 level, EF maximum diameter at the L5-S1 level, spinal canal antero-posterior diameter at the L5-S1 level, and subcutaneous fat (SF) when included in the MRI images (at the L3 level) in all the MRI scans. Results: A cohort of 516 patients was collected (320 women and 196 men; mean age 57.31 ± 18.45 years old). In 508 patients (98.4%) SF and VAT were both measurable, while in 8 patients VAT only was assessable on MRI scans. Pearson correlation identified significant associations between EF and VAT thickness (correlation coefficient > 20%; p < 0.05). A linear regression model confirmed a significant, albeit modest, positive relationship between VAT and EF (R2 = 5.4%). A multivariate regression model incorporating age, sex, spinal canal size, VAT, and SF improved the explanatory power (adjusted R2 = 16.7%), with VAT, spinal canal diameter, and age emerging as significant predictors of EF (p < 0.001). Conclusions: Our study revealed in a large cohort of patients that EF and VAT are directly associated. On the other hand, SF resulted in not being associated with EF. These findings support the emerging concept that SEL can be a radiological phenotype of visceral obesity and, by extension, of MS. Integrating EF measurement into standard MRI interpretation may facilitate the early detection of SEL and offer additional insights into patients’ underlying metabolic profile. Full article

Metabolic syndrome (MetS) is a global public health challenge, characterized by the coexistence of cardiometabolic risk factors such as abdominal obesity, dyslipidaemia, hypertension, and insulin resistance. Non-pharmacological strategies, including the Mediterranean diet (MD) and physical activity (PA), have been widely studied for their potential to prevent and manage MetS. This systematic review aimed to synthesize the evidence on the combined effect of MD and PA on MetS components in adults, based on randomized controlled trials (RCTs). Twenty-two RCTs published between 2018 and 2024 were included, involving 11,478 participants. The interventions ranged from 8 weeks to 3 years and combined adapted or hypocaloric MDs with moderate-to-high-intensity PA, typically including walking, aerobic exercise, or high-intensity interval training (HIIT), performed 3 to 7 times per week. The combined interventions resulted in reductions in body weight (−2.5 to −7.2 kg), body mass index (−0.7 to −2.2 kg/m2), waist circumference (−5.1 to −7.8 cm), and blood pressure (up to −9.0 mmHg systolic and −6.7 mmHg diastolic). Improvements in HDL cholesterol, triglyceride levels, and insulin sensitivity were also observed. These findings suggest that integrated interventions based on the Mediterranean lifestyle are effective in reducing MetS components and may support future public health strategies. Full article

Metabolic syndrome refers to a group of conditions that commonly occur together, including abdominal obesity, high blood pressure, elevated blood sugar, high triglyceride levels, and low high-density lipoprotein cholesterol (HDL). These factors collectively increase the risk of cardiovascular disease, diabetes, and cognitive impairment. Recent research has identified a connection between metabolic syndrome and cognitive disorders such as mild cognitive impairment and vascular dementia (VaD). Mulberry (Morus alba L.) is a natural source of bioactive compounds with antioxidant, anti-inflammatory, and lipid-regulating properties. This meta-analysis assessed the potential of mulberry extract as an adjunctive treatment for metabolic risk factors linked to vascular dementia. We systematically reviewed randomized controlled trials (RCTs) published up to May 2025 that compared mulberry extract to placebo or standard care in adults with metabolic disorders. Fifteen trials including 1202 participants met the inclusion criteria. The primary outcomes were fasting glucose, fasting insulin, liver enzyme levels, lipid profiles, and inflammatory markers such as tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and high-sensitivity C-reactive protein (hs-CRP). The pooled results indicated that mulberry supplementation improved blood sugar control and lowered total cholesterol, low-density lipoprotein cholesterol (LDL), triglycerides, fasting blood glucose, glycosylated hemoglobin (HbA1c), homeostasis model assessment for insulin resistance (HOMA-IR), and inflammatory markers. Aspartate aminotransferase (AST) improved, whereas alanine aminotransferase (ALT) showed no significant change. Subgroup analyses revealed that greater benefits were associated with shorter treatment durations and doses below 500 milligrams per day. Furthermore, extracts from different parts of the mulberry plant showed varying effects on lipid and glucose metabolism. None of the included trials directly measured cognitive or neurovascular outcomes, so any potential neurovascular protection is inferred from changes in metabolic and inflammatory markers rather than demonstrated. In summary, these findings suggest that mulberry extract may be a promising complementary approach for managing metabolic risk factors in people at risk for VaD. However, further large-scale and rigorously designed studies are required to confirm its clinical benefits and to identify the most effective preparations. Full article

Abstract
Metabolic syndrome (MetS)—characterized by dyslipidemia, hypertension, hyperglycemia, and abdominal obesity—is a common, modifiable condition that contributes to functional decline and premature mortality in older adults. The accumulation of MetS components increases the risk of cardiovascular, cerebrovascular, and renal diseases, as well as cognitive [...] Read more.
Metabolic syndrome (MetS)—characterized by dyslipidemia, hypertension, hyperglycemia, and abdominal obesity—is a common, modifiable condition that contributes to functional decline and premature mortality in older adults. The accumulation of MetS components increases the risk of cardiovascular, cerebrovascular, and renal diseases, as well as cognitive impairment and polypharmacy in aging populations. A narrative review was conducted focusing on the management of MetS in adults aged 65 and older. Sources were identified through targeted searches of PubMed and relevant guidelines, with an emphasis on literature discussing geriatric-specific considerations. The review was structured using the Institute for Healthcare Improvement’s (IHI) 4Ms Framework: What Matters, Medication, Mentation, and Mobility. Findings highlight that current MetS guidelines are often extrapolated from younger populations and insufficiently account for geriatric-specific factors such as altered pharmacokinetics, multimorbidity, and social determinants of health. The 4Ms Framework provides a comprehensive lens to adapt these guidelines, supporting individualized treatment plans that consider patient goals, cognitive status, and functional capacity. Incorporating social services and aligning interventions with socioeconomic realities can further bridge disparities in care. The 4Ms framework can help healthcare providers communicate effectively with patients, ensuring treatment plans align with evidence-based practices and the patient’s individual priorities. Treatment of MetS must be tailored to individual patient needs based on presented risk factors, severity of risks, and social determinants of health. Adjusting treatment plans in accordance with the socioeconomic status (SES) of patients will allow for systematic improvement of outcomes. Full article

Background: Fetuin-A, a hepatokine implicated in metabolic regulation, has been associated with both metabolic syndrome and cardiovascular disease. However, its specific role in type 2 diabetes mellitus (T2DM) remains incompletely understood. Objective: This study aimed to investigate the relationship between fetuin-A levels and key components of metabolic syndrome (abdominal obesity, arterial hypertension, hyperglycemia, hypertriglyceridemia and low high-density lipoprotein cholesterol) as well as other cardiovascular risk markers, including metabolic dysfunction-associated fatty liver disease (MAFLD), carotid intima-media thickness (CIMT), and the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR). Methods: A total of 51 patients with T2DM not receiving insulin therapy were enrolled. Participants underwent clinical, biochemical, and imaging evaluations. Hepatic steatosis was assessed via abdominal ultrasonography, and subclinical atherosclerosis was evaluated using CIMT measured with Doppler ultrasonography. Serum fetuin-A was quantified by ELISA. Results: Hepatic steatosis was significantly associated with metabolic syndrome, increased CIMT, and dyslipidemia (elevated total cholesterol, triglycerides, and reduced HDL cholesterol). Although no direct correlation was found between fetuin-A levels and hepatic steatosis, multivariate analysis revealed that fetuin-A concentrations were significantly influenced by total cholesterol and LDL cholesterol levels. Conclusions: Fetuin-A appears to be linked to lipid abnormalities in T2DM and may contribute to cardiovascular risk in this population. These findings support the potential utility of fetuin-A as a biomarker and possible therapeutic target for dyslipidemia management in diabetic patients. Full article

Background and Objectives: Metabolic syndrome (MetS) progresses gradually as individual components accumulate. However, there is limited understanding regarding whether the sequence of component appearance influences disease progression. This study sought to determine the most frequent initial MetS component and evaluate whether this component influences the subsequent risk of developing full MetS. Materials and Methods: We examined data from 6137 participants in the Korean Genome and Epidemiology Study (KoGES), free of MetS at baseline (2001–2002), followed until 2011–2012. Participants were stratified by the first emerging MetS component: abdominal obesity, elevated blood pressure, high fasting glucose, high triglycerides, or low HDL cholesterol. The primary endpoint was progression to full MetS, defined as the development of three or more components. We also assessed transition probabilities between components and sex-specific sequence differences. Results: Abdominal obesity was the most frequent initial metabolic abnormality (31.0%), followed by elevated blood pressure (26.3%), low HDL cholesterol (15.3%), high triglycerides (13.7%), and high fasting glucose (4.9%). Over a median 8.2-year follow-up, participants with initial abdominal obesity exhibited the greatest progression rate to full MetS (44.4%), significantly higher than those with elevated blood pressure (24.8%), high triglycerides (23.0%), high fasting glucose (21.6%), or low HDL cholesterol (9.3%) (all p < 0.001). After controlling for age, sex, smoking status, and baseline BMI, initial abdominal obesity was associated with a 4.77-fold increased risk (95% CI: 3.68–6.18) of developing full MetS compared to initial low HDL cholesterol. Distinct transition patterns were observed: high triglycerides frequently transitioned to low HDL cholesterol (78.1%), while abdominal obesity most often led to elevated blood pressure (52.1%). Marked sex-related differences were also found: abdominal obesity was more common initially among women (41.7% vs. 25.2%), whereas elevated blood pressure was predominant among men (37.6% vs. 21.2%). Conclusions: The initial MetS component strongly predicts progression to full syndrome, with abdominal obesity conferring the highest risk. Early identification and targeted interventions addressing abdominal obesity may effectively prevent MetS and its subsequent complications. Full article
