This study aimed to assess trends in cardiovascular and diabetes-related metabolic biomarkers among U.S. adults from 2013-2014 to 2021-2023. DESIGN, SETTING, AND PARTICIPANTS This study analyzed five cycles of cross-sectional data from the National Health and Nutrition Examination Survey (NHANES) spanning 2013-2014 to 2021-2023. The sample was weighted to reflect the noninstitutionalized civilian U.S. population aged 18 and older. Data analysis was conducted from August to October 2024. EXPOSURES Calendar year and sociodemographic subgroups, including age, gender, race, educational level, and family poverty-to-income ratio. MAIN OUTCOMES AND MEASURES Primary outcomes included body mass index (BMI), waist circumference, body fat percentage, systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse rate, estimated pulse wave velocity (ePWV), fasting glucose, glycohemoglobin, total fasting cholesterol, high-density lipoprotein cholesterol (HDL-C), fasting insulin, and insulin resistance index. Trends were estimated using survey-weighted linear regression models. RESULTS A total of 10,337 participants were included. BMI, waist circumference, and body fat percentage showed significant increases (all P for trend < 0.05). Specifically, BMI increased from 28.54 kg/m² (95% CI: 28.18-28.91) to 29.43 kg/m² (95% CI: 28.85-30.01); waist circumference rose from 97.63 cm (95% CI: 96.86-98.40) to 100.11 cm (95% CI: 98.77-101.44); and body fat percentage increased from 33.59% (95% CI: 31.11-34.07%) to 35.68% (95% CI: 34.90-36.46%). Significant interactions for these biomarkers were observed among various education and income subgroups. DBP ( P < 0.0001) and ePWV ( P < 0.0001) also increased, with DBP rising from 68.01 mmHg (95% CI: 67.42-68.60) to 74.17 mmHg (95% CI: 73.29-76.06) and ePWV from 7.89 m/s (95% CI: 7.75-8.02) to 8.41 m/s (95% CI: 8.27-8.55), while pulse rate declined from 72.27 bpm (95% CI: 71.17-73.37) to 70.59 bpm (95% CI: 69.96-71.23) ( P < 0.0001). Although SBP did not show an overall significant trend, increases were observed among men (from 121.06 mmHg [95% CI: 119.87-122.25] to 123.27 mmHg [95% CI: 122.41-124.12], P for trend = 0.005) and individuals with less than a high school education (from 117.56 mmHg [95% CI: 115.77-119.34] to 124.55 mmHg [95% CI: 121.81-127.30], P for trend < 0.0001). No significant trends were found for total cholesterol and HDL-C. Fasting glucose and glycohemoglobin showed significant upward trends (P for trend = 0.001 and 0.027, respectively), with notable increases in Mexican Americans (fasting glucose: 5.90 mmol/L [95% CI: 5.81-6.00] to 6.64 mmol/L [95% CI: 6.26-7.01], P for trend < 0.0001; glycohemoglobin: 5.59% [95% CI: 5.51-5.68] to 6.06% [95% CI: 5.84-6.28], P for trend < 0.001). CONCLUSIONS AND RELEVANCE Analysis of NHANES data indicates that most cardiovascular and diabetes-related metabolic biomarkers significantly increased from 2013-2014 to 2021-2023, with notable differences across demographic groups. These findings can help shape targeted prevention strategies, especially for addressing the needs of diverse populations. Figures Figure 1 Figure 2 Figure 3 Figure 4 Introduction Cardiovascular disease (CVD) and diabetes are leading causes of disability and mortality globally 1 , 2 . From 1990 to 2019, total CVD cases nearly doubled, rising from 271 million to 523 million, while CVD-related deaths grew from 12.1 million to 18.6 million 3 . Managing CVD imposes a significant economic burden; in 2020, one in three adults in the U.S. required care for a cardiovascular risk factor or condition. By 2035, the annual healthcare costs for CVD are projected to increase nearly fourfold from $ 393 billion to $ 1.49 trillion, with productivity losses expected to grow by 54%, from $ 234 billion to $ 361 billion 4 . Between 1990 and 2021, the global age-standardized prevalence of diabetes rose by 90.5%, from 3.2–6.1%, affecting 529 million individuals by 2021. Forecasts indicate a further 59.7% increase in prevalence by 2050, reaching 9.8%, with 1.31 billion people expected to have diabetes 5 . In the U.S., diabetes-related costs were estimated at $ 327 billion in 2017, accounting for 24% of healthcare expenditures, rising to $ 412.9 billion by 2022, including $ 306.6 billion in direct medical costs and $ 106.3 billion in indirect costs 6 , 7 . CVD and diabetes are closely interconnected, sharing several risk factors, such as obesity, smoking, and physical inactivity, with diabetes itself serving as a CVD risk factor 8 . Adults with diabetes face a 2–4 times higher risk of cardiovascular events compared to those without diabetes, and this risk escalates with poor glycemic control 9 . Modifiable risk factors, including body mass index (BMI), blood pressure, cholesterol levels, smoking, and diabetes, contribute significantly to the incidence and prevalence of CVD 10 – 12 . Preventing CVD in diabetic patients requires managing risk factors, such as glycohemoglobin, blood pressure, and cholesterol levels 13 , 14 . Although control over these factors (e.g., glycohemoglobin < 7.0%, blood pressure < 130/80 mmHg, low-density lipoprotein cholesterol < 100 mg/dL) improved from 1988 to 2010, only about 18.8% of U.S. adults met all three targets by 2007-2010 15,16 . Between 2020 and 2023, the Coronavirus disease 2019 (COVID-19) pandemic added additional complexities, with CVD and diabetes being potential long-term outcomes of infection. COVID-19 patients exhibited a significantly higher risk of all cardiovascular outcomes than non-infected individuals (HR 1.66 [1.62–1.71] for those with diabetes; HR 1.75 [1.73–1.78]) 17 . Additionally, "Long COVID" may continue affecting cardiovascular health with fluctuating symptoms over time 18 . The trends in CVD and diabetic metabolic biomarkers remain unclear, especially following the pandemic, the understanding of these trends is paramount for population-level health complications and prevention efforts. Using recent National Health and Nutrition Examination Survey (NHANES) data, this study primarily aimed to provide national estimates to assess trends in CVD and diabetes-related metabolic biomarkers among adults in U.S from 2013 to 2023. Methods The First Affiliated Hospital of Guangzhou University of Chinese Medicine Ethics Committee deemed this cross-sectional study exempt from ethical review and informed consent because publicly available and deidentified NHANES data were used. For NHANES cycles, researchers recruit participants using established consent protocols approved by the National Center for Health Statistics Institutional Review Board 19 . Details of the data collection procedures, study design, and protocol were published previously 20 . This study followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guideline. Data source and study population We used data from the NHANES, which is conducted biennially by the US Centers for Disease Control and Prevention (CDC) for public health surveillance 21 . The CDC has disclosed NHANES data during the COVID-19 pandemic. Therefore, we used data from NHANES cycles from 2013 to August 2023. Because data collection for the 2019-2020 NHANES cycle was not completed and the collected data were not nationally representative, we used 2017-2020 prepandemic NHANES data to ensure nationally representative estimates 22 . NHANES cycle August 2021- August 2023 was used to represent data on the pandemic. We excluded participants with missing data on age, gender, race, FPIR, educational attainment, and cardiovascular disease or diabetes-related metabolic biomarkers. The patient selection flowchart is shown in Supplementary Figure 1. Measurement of cardiovascular disease and diabetes-related metabolic biomarkers We included a total of 15 cardiovascular and diabetes-related metabolic biomarkers, including body mass index (BMI), waist circumference, body fat percentage, systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse rate, estimated pulse wave velocity (ePWV), fasting glucose, glycohemoglobin, fasting total cholesterol, high-density lipoprotein-cholesterol(HDL-C), fasting insulin, and insulin resistance index. BMI and waist circumference were derived from body measurements collected by trained health technicians at the Mobile Examination Center (MEC). The body fat percentage (BF%) was calculated using the following formula: BF% = -44.988 + (0.503 × age) + (10.689 × sex) + (3.172 × BMI) - (0.026 × BMI 2 ) + (0.181 × BMI × sex) - (0.02 × BMI × age) - (0.005 × BMI 2 × sex) + (0.00021 × BMI 2 × age). Where sex is coded as 0 for male and 1 for female, and age is in years 23 . The SBP and DBP measurements were taken following these guidelines: after a 5-minute rest in a seated position, three consecutive BP readings were obtained once the maximum inflation level was established. If a measurement was interrupted or incomplete, a fourth attempt was made. The pulse rate was measured by locating the radial pulse with the participant's elbow and forearm resting comfortably on a table, palm facing up, and counting for 30 seconds. The ePWV was calculated with the following formula 24 : No cardiovascular disease risk factor: 4.62-0.13 × age + 0.0018 × age 2 + 0.0006 × age × mean arterial pressure (MAP) + 0.0284 × MAP ≥1 cardiovascular disease risk factor: 9.587-0.402 × age + 4.560 × 10 -3 × age 2 -2.621 × 10 -5 × age 2 × MAP + 3.176 × 10 -3 × age × MAP - 1.832 × 10 -2 × MAP The MAP was calculated as: (DBP) + 0.4 × ([SBP]-DBP) Fasting glucose levels were determined using an enzymatic method in which glucose is converted to glucose-6-phosphate by hexokinase in the presence of ATP. The glucose-6-phosphate dehydrogenase then converts G-6-P to gluconate-6-phosphate in the presence of NADP+. The reduction of NADP+ to NADPH was measured by the increase in absorbance at 340 nm (secondary wavelength = 700 nm). Glycohemoglobin was measured by diluting the whole blood sample with a hemolysis solution, followed by injection into an HPLC analytical column. The separated hemoglobin components passed through a photometric flow cell, with absorbance changes measured at 415 nm. Total cholesterol was measured using an enzymatic assay in which esterified cholesterol was converted to free cholesterol by cholesterol esterase. Cholesterol oxidase then converted the cholesterol to cholest-4-en-3-one and hydrogen peroxide, which reacted with 4-aminophenazone in the presence of peroxidase, forming a colored product measured at 505 nm (secondary wavelength = 700 nm). HDL cholesterol was measured using a method involving magnesium/dextran sulfate to form water-soluble complexes with non-HDL fractions, followed by conversion of HDL cholesterol esters to HDL cholesterol. Subsequent oxidation produced hydrogen peroxide, which combined with 4-amino-antipyrine and HSDA under the action of peroxidase to form a pigment measured at 600 nm (secondary wavelength = 700 nm). Fasting insulin was quantified using the AIA-PACK IRI, a two-site immunoenzymometric assay performed on a Tosoh AIA System analyzer. Insulin in the sample was bound to a monoclonal antibody on a magnetic solid phase and an enzyme-labeled monoclonal antibody. The amount of enzyme-labeled antibody bound was proportional to the insulin concentration and was quantified using a standard curve. The Homeostasis Model Assessment (HOMA) included calculations for HOMA-IR (insulin resistance), HOMA-IS (insulin sensitivity), and HOMA-β% (β-cell function), with the formulas as follows 25 : HOMA-IR: (fasting glucose [mmol/L)] × fasting insulin [mIU/L]/22.5) HOMA-IS:1/HOMA-IR HOMA-β%: 20 × fasting insulin (uU/mL) / (fasting glucos(mmol/L) - 3.5) Statistical analysis We adjusted the weights for the prepandemic period following official guidelines to reduce potential bias. The analysis utilized NHANES Mobile Examination Center (MEC) exam weights, incorporating sampling, stratification, and clustering to produce nationally representative estimates 26 . While the 2017-2020 prepandemic NHANES data file spans 3.2 years, the other NHANES cycles cover 2 years each. To account for this discrepancy, we adjusted the survey weights when combining the 2017-2020 data with other 2-year cycles, ensuring they reflected the extended time frame and larger population. New multicycle sample weights were derived based on the combined survey periods (2013-2014, 2015-2016, 2017-2020, and 2021-2023, totaling 9.2 years) using the formulas: (1) Weight = Weight × (2/9.2) for the 2013-2014, 2015-2016, or 2021-2023 cycles, and (2) Weight = Weight × (3.2/9.2) for the 2017-2020 cycle. In this study, baseline characteristics of participants were described by survey cycle. Means (with standard errors) were reported for continuous variables, while percentages were presented for categorical variables. Given the skewed distribution ofcardiovascular disease and diabetes-related metabolic biomarkers , we calculated geometric means (referred to hereafter as means) for these measures. Confidence intervals were determined using Taylor series linearization. To assess trends over time, we applied a survey-weighted linear regression model, treating the survey cycle as a continuous variable 26 . A total of three statistical models were constructed in each analysis. The crude model was the non-adjusted model with no covariates adjusted. Model I adjusted for age and gender. Model II adjusted for age, gender, race, education, and FPIR. Potential variations in trends across subgroups were evaluated using survey-weighted Wald F statistics 27 , assessing interactions between survey cycles and subgroup indicators such as age, gender, race, educational level, and family poverty-to-income ratio (FPIR). Statistical analysis was conducted using R software (version 4.3.1), with the NHANES survey design accounted for via the survey package. Statistical significance was set at p < 0.05 (two-tailed). Data analysis was performed between August and October 2024. Results Baseline characteristics of the participants A total of 10,337 participants were included in the study, distributed across four NHANES cycles: 2,650 from the 2013-2014 cycle, 2,446 from the 2015-2016 cycle, 2,755 from the 2017-2020 cycle, and 2,486 from the 2021-2023 cycle ( Table 1 ). There were no significant differences in age distribution, gender, or race across the four cycles. However, significant variations were observed in educational attainment and FPIR, with a higher proportion of participants having higher education and income levels in the 2017-2020 and 2021-2023 cycles. Additionally, BMI, waist circumference, systolic blood pressure, diastolic blood pressure, body fat percentage, fasting blood glucose, total cholesterol, glycohemoglobin, HOMA-IS, ePWV, and pulse rate showed significant differences across the cycles. Trends in BMI, Waist Circumference, and BF% From 2013-2014 to 2021-2023, the mean BMI rose from 28.54 kg/m² (95% CI: 28.18-28.91) to 29.43 kg/m² (95% CI: 28.85-30.01), with a significant trend ( P = 0.003; Figure 1A and Table 2 ). Similarly, the mean waist circumference increased from 97.63 cm (95% CI: 96.86-98.40) to 100.11 cm (95% CI: 98.77-101.44), with a trend P -value < 0.001 ( Figure 1B and Table 2 ). BF% also showed an upward trend, increasing from 33.59% (95% CI: 31.11-34.07%) to 35.68% (95% CI: 34.90-36.46%), with a trend P -value < 0.0001 ( Figure 1C and Table 2 ). While BMI and waist circumference saw a decline in 2021-2023 compared to the pre-pandemic period (2017-2020), body fat percentage continued to rise. Notably, changes in BMI, waist circumference, and BF% varied significantly based on educational level, with interaction P -values of 0.026, <0.001, and <0.001, respectively ( Supplementary Table 1 ). Among participants with less than high school education during the same period, BMI increased from 26.92 kg/m² (95% CI: 26.33-27.51) to 29.71 kg/m² (95% CI: 28.74-30.67), with a trend P -value < 0.0001 ( Supplementary Table 1 and Supplementary Figure 2A ). Waist circumference also rose from 92.06 cm (95% CI: 90.32-93.80) to 101.43 cm (95% CI: 99.23-103.62), with a trend P-value < 0.0001 ( Supplementary Table 1 and Supplementary Figure 2B ). BF% increased from 30.13% (95% CI: 28.97-31.29%) to 35.49% (95% CI: 33.48-37.51%), with a trend P -value < 0.0001 ( Supplementary Table 1 and Supplementary Figure 2C ). BMI, waist circumference, and BF% trends also varied significantly by FPIR level, with interaction P -values of 0.003, <0.001, and 0.002, respectively ( Supplementary Table 1 ). A marked increase was observed among low-income groups (0 < FPIR < 1). From 2013-2014 to 2021-2023, BMI rose from 28.75 kg/m² (95% CI: 28.28-29.23) to 29.82 kg/m² (95% CI: 28.79-30.86), with a trend P -value of 0.002 ( Supplementary Table 1 and Supplementary Figure 2D ). Waist circumference increased from 97.08 cm (95% CI: 95.41-98.74) to 100.39 cm (95% CI: 98.04-102.74), with a trend P -value < 0.001 ( Supplementary Table 1 and Supplementary Figure 2E ). BF% grew from 33.39% (95% CI: 32.80-33.98%) to 36.66% (95% CI: 34.98-38.54%), with a trend P -value < 0.0001 ( Supplementary Table 1 and Supplementary Figure 2F ). Trends in SBP, DBP, Pulse Rate, and ePWV The rise in DBP was more prominent than that in SBP. The mean SBP increased from 119.63 mmHg (95% CI: 118.61-120.65) in 2013-2014 to 120.25 mmHg (95% CI: 119.47-121.03) in 2021-2023 ( P for trend = 0.0689) ( Figure 2A and Table 2 ). Meanwhile, the mean DBP significantly rose from 68.01 mmHg (95% CI: 67.42-68.60) to 74.17 mmHg (95% CI: 73.29-76.06), with a trend P -value < 0.0001 ( Figure 2B and Table 2 ). Conversely, the pulse rate decreased from 72.27 bpm (95% CI: 71.17-73.37) to 70.59 bpm (95% CI: 69.96-71.23), with a trend P -value < 0.0001 ( Figure 2C and Table 2 ), though there was a subsequent rise in 2021-2023 compared to 2017-2020. The ePWV increased significantly from 7.89 m/s (95% CI: 7.75-8.02) to 8.41 m/s (95% CI: 8.27-8.55), with a trend P -value < 0.0001 ( Figure 2D and Table 2 ). SBP trends differed significantly by gender and educational level ( P for interaction = 0.006 and < 0.0001, respectively) ( Supplementary Table 2 and Supplementary Figure 3A-B ). In males, SBP rose from 121.06 mmHg (95% CI: 119.87-122.25) to 123.27 mmHg (95% CI: 122.41-124.12) ( P for trend = 0.005). For females, a slight decrease was observed from 118.24 mmHg (95% CI: 116.97-119.51) to 117.41 mmHg (95% CI: 116.17-118.66), though the trend was not statistically significant ( P for trend = 0.101). Participants with less than a high school education experienced a significant increase in SBP from 117.56 mmHg (95% CI: 115.77-119.34) to 124.55 mmHg (95% CI: 121.81-127.30) ( P for trend < 0.0001). DBP showed significant variations across race, education, and FPIR ( P for interaction = 0.004, <0.0001, and 0.004, respectively) ( Supplementary Table 2 and Supplementary Figure 3C-E ). The largest increases in DBP occurred among non-Hispanic Black individuals (68.16 mmHg [95% CI: 66.74-69.58] in 2013-2014 to 78.71 mmHg [95% CI: 76.29-81.14] in 2021-2023, P for trend < 0.0001), participants with less than a high school education (64.15 mmHg [95% CI: 63.14-65.17] to 75.17 mmHg [95% CI: 73.03-77.30], P for trend < 0.0001), and low-income individuals (67.65 mmHg [95% CI: 66.25-69.05] to 74.87 mmHg [95% CI: 72.96-76.79], P for trend < 0.0001). Differences in pulse rate were observed between elderly and non-elderly individuals ( P for interaction = 0.027) ( Supplementary Table 2 and Supplementary Figure 3F ). The mean pulse rate (95% CI) in non-elderly individuals showed a significant decrease, from 73.16 bpm (72.02, 74.3) in 2013-2014 to 71.42 bpm (70.84, 72) in 2021-2023 ( P for trend < 0.0001). Differences in ePWV were noted among populations with varying educational attainment and different FPIR levels ( P for interaction < 0.0001 and 0.005, respectively), with the most pronounced differences observed in individuals with less than a high school education and in low-income groups ( Supplementary Table 2 and Supplementary Figure 3G-H ). Among individuals with less than a high school education, the mean ePWV (95% CI) increased from 7.55 m/s (7.34, 7.76) in 2013-2014 to 8.79 m/s (8.38, 9.2) in 2021-2023 ( P for trend < 0.0001). In the low-income group (0 < FPIR < 1), the mean ePWV (95% CI) rose from 7.41 m/s (7.26, 7.56) in 2013-2014 to 8.16 m/s (7.9, 8.41) in 2021-2023 ( P for trend < 0.0001). Trends in Total Cholesterol and HDL-C Overall, no significant changes were observed in total cholesterol or HDL-C levels from 2013 to 2023 ( P for trend = 0.083 and 0.657, respectively) ( Figure 3 and Table 2 ). However, significant interactions with age and educational level were found for total cholesterol ( P for interaction < 0.001 and 0.006). Among non-elderly individuals, total cholesterol rose from 4.78 mmol/L (95% CI: 4.72-4.85) to 4.96 mmol/L (95% CI: 4.89-5.03) ( P for trend = 0.005), while in the elderly, it decreased from 4.81 mmol/L (95% CI: 4.72-4.90) to 4.66 mmol/L (95% CI: 4.58-4.74) ( P for trend = 0.002) ( Supplementary Table 3 and Supplementary Figure 3A ). Participants with less than a high school education saw a rise in total cholesterol from 4.48 mmol/L (95% CI: 4.42-4.54) to 4.76 mmol/L (95% CI: 4.60-4.92) ( P for trend < 0.0001) ( Supplementary Table 3 and Supplementary Figure 3B ). Trends in Fasting Glucose, Glycohemoglobin, Fasting Insulin, and HOMA From 2013 to 2023, fasting glucose and glycohemoglobin levels showed upward trends ( P for trend = 0.001 and 0.027, respectively) ( Figure 4A-B and Table 2 ), while no significant changes were noted in fasting insulin or HOMA scores ( Figure 4C-F and Table 2 ). Fasting glucose increased from 5.77 mmol/L (95% CI: 5.69-5.85) to 5.99 mmol/L (95% CI: 5.88-6.09), and glycohemoglobin rose from 5.58% (95% CI: 5.53-5.62) to 5.67% (95% CI: 5.60-5.74). Among participants who graduated high school, fasting glucose levels increased from 5.82 mmol/L (95% CI: 5.64-6.01) to 6.16 mmol/L (95% CI: 5.93-6.39) ( P for trend = 0.021). For those with less than a high school education, levels rose from 5.75 mmol/L (95% CI: 5.60-5.89) to 6.54 mmol/L (95% CI: 6.24-6.85) ( P for trend < 0.0001) ( Supplementary Table 4 and Supplementary Figure 5A ). Although there was no significant interaction for race ( P = 0.179), a marked increase was seen in Mexican Americans (5.90 mmol/L [95% CI: 5.81-6.00] to 6.64 mmol/L [95% CI: 6.26-7.01], P for trend < 0.0001) ( Supplementary Table 4 and Supplementary Figure 5B ). Similar trends were observed for glycohemoglobin, with significant variations based on educational level and FRIR level ( P for interaction < 0.0001 and 0.022) ( Supplementary Table 4 and Supplementary Figure 5C-D ). Among those with lower education levels, glycohemoglobin increased from 5.58% (95% CI: 5.51-5.66) to 6.14% (95% CI: 5.96-6.32) ( P for trend < 0.0001). There were also differences across FRIR levels, particularly in low-income and middle-income groups, where glycohemoglobin rose from 5.58% (95% CI: 5.48-5.67) to 5.76% (95% CI: 5.63-5.89) ( P for trend = 0.002) and from 5.64% (95% CI: 5.57-5.71) to 5.76% (95% CI: 5.68-5.84) ( P for trend = 0.004). Despite a non-significant interaction P -value for race (P = 0.118), Mexican Americans exhibited a significant increase (5.59% [95% CI: 5.51-5.68] to 6.06% [95% CI: 5.84-6.28], P for trend < 0.001) ( Supplementary Table 4 and Supplementary Figure 5E ). No significant subgroup differences were found for HOMA-IR and HOMA-β. However, HOMA-IS varied with age, declining in the elderly from 0.60 (95% CI: 0.54-0.65) to 0.51 (95% CI: 0.48-0.55) ( Supplementary Table 4 and Supplementary Figure 5F ). Although the interaction P -value for race was not statistically significant ( P = 0.072), a substantial decline was noted among non-Hispanic Black participants (0.75 [95% CI: 0.65-0.85] to 0.51 [95% CI: 0.45-0.57], P for trend < 0.001) ( Supplementary Table 4 and Supplementary Figure 5G ). Discussion To our knowledge, this study represents the first in-depth analysis of trends in cardiovascular and diabetic metabolic biomarkers over time in the US population, encompassing the period during the COVID-19 pandemic. We observed an upward trend in most biomarkers, including BMI, waist circumference, BF%, DBP, ePWV, fasting glucose, and glycohemoglobin, while pulse rate showed a declining trend. Peak values for BMI, waist circumference, and fasting glucose were reached in the 2017-2020 cycle, while body fat, DBP, and ePWV continued to rise in the 2021-2023 cycle. Trends varied across different population subgroups, with education and income identified as significant subgroup characteristics. BMI, waist circumference, BF%, SBP, ePWV, and glycated hemoglobin showed differences between these subgroups. Differences in pulse rate, total cholesterol, and HOMA-IS were noted between older and younger groups. Variations in SBP were also observed across racial groups; although these differences were not mirrored in fasting glucose and glycohemoglobin, both biomarkers significantly increased in the Mexican American subgroup. We first assessed trends in BMI, waist circumference, and BF%, as these three indicators are commonly used to evaluate an individual's cardiometabolic risk. BMI is strongly associated with an increased risk of CVD and diabetes. Compared with individuals of normal weight, competing hazard ratios for incident CVD were 1.21 (95% CI: 1.14-1.28) and 1.32 (95% CI: 1.24-1.40) among overweight men and women (BMI, 25.0-29.9 kg/m 2 ), respectively 28 . Lifetime diabetes risk at age 18 rose from 7.6% to 70.3% among men and from 12.2% to 74.4% among women between underweight and severely obese (BMI >35 kg/m 2 ) categories 29 . However, the limitations of BMI in fully capturing cardiometabolic risk are partly due to its inadequacy as a standalone biomarker for abdominal adiposity 30 . Waist circumference, which is simple to standardize clinically, provides a straightforward measure of abdominal adiposity and is strongly associated with all-cause mortality 31 . Additionally, we assessed BF%, which reflects body composition more accurately than BMI and demonstrates stronger associations with cardiometabolic conditions 32 . Notably, a longitudinal study reported a statistically significant change in total fat percentage before and after the COVID-19 pandemic 33 . The observed subgroup differences in these three biomarkers align with previous studies. For example, a multi-round survey of California adults from 2011 to 2014 indicated an inverse relationship between obesity and household income 34 . Furthermore, BMI and waist circumference were significantly lower across all three higher education categories (vocational secondary, other secondary, and university degree) compared to the lowest education level 35 . Our findings suggest an upward trend in these three biomarkers over the past decade, with low-income and low-education populations being particularly vulnerable. We subsequently conducted a trend analysis of cardiovascular physical examination indicators, including SBP, DBP, pulse rate, and ePWV. Our findings indicate that SBP levels remained well-controlled with no significant upward trend; however, DBP levels showed a marked increase. A comparative study on the impact of systolic and diastolic blood pressures on cardiovascular outcomes found that both SBP and DBP independently contribute to adverse cardiovascular events. In survival models, continuous systolic hypertension (≥140 mmHg) was associated with a hazard ratio per unit increase in z-score of 1.18 (95% CI: 1.17-1.18), while diastolic hypertension (≥90 mmHg) had a hazard ratio of 1.06 (95% CI: 1.06-1.07) 36 . Additionally, the study demonstrated a "J"-shaped relationship between DBP and cardiovascular outcomes, suggesting that both excessively high and low DBP levels may increase the risk of adverse cardiovascular events 36 . Consequently, while elevated DBP in our study may not directly raise cardiovascular event risk, suggesting more robust SBP-lowering strategies that can avoid significant DBP reduction. ePWV, a marker of arterial stiffness reflecting arterial health and aging, was calculated from age and mean BP using an equation from the Reference Values for Arterial Stiffness Collaboration 37 . ePWV is predictive of mortality and cardiovascular risk, correlating with all-cause mortality (HR per 1 m/s increase, 1.13; 95% CI: 1.05-1.21) and myocardial infarction (HR per 1 m/s increase, 1.23; 95% CI: 1.09-1.39) 38 . Our study observed a significant rise in ePWV during the COVID-19 pandemic, consistent with prior research showing progressive ePWV increases across control groups, COVID-19 survivors, and deceased patients (mean adjusted increase per group 1.89 m/s, P < 0.001), suggesting its potential role as a marker related to COVID-19 severity and possibly indicating long-term impacts in cardiovascular diseases outcome 39 . Total cholesterol and HDL levels are indicators of lipid metabolism. Elevated total cholesterol has been associated with increased CVD risk 40 and is also commonly linked to metabolic disturbances in diabetes 41 . Although we did not observe a significant trend in cholesterol levels overall, subgroup analysis revealed a notable decline in TC among the elderly, suggesting improved cholesterol control in this group. Conversely, Total cholesterol showed a significant increase among participants with lower education levels, underscoring a need for targeted attention in these populations. To assess diabetes-related metabolic biomarkers, we included fasting blood glucose, fasting insulin, glycohemoglobin, and HOMA-IR. fasting blood glucose and glycohemoglobin showed significant upward trends, particularly among Mexican Americans. Another study based on NHANES data indicated that the estimated prevalence of diabetes has continued to rise significantly among Mexican American adults 42 , suggesting that this disparity may partly be attributed to higher insurance coverage and greater access to preventive services compared to other minority groups 43,44 . While some cohort studies have reported elevated blood glucose, reduced insulin levels, and increased insulin resistance during and post-COVID-19 infection compared to healthy controls, a broader, long-term national sampling study found that the COVID-19 pandemic did not significantly affect diabetes-related biomarkers 45,46 . Limitations This study has several limitations. First, our analysis included data encompassing the COVID-19 pandemic period (2021-2023 cycle). However, COVID-19 infection status was not reported for participants during this cycle, limiting our ability to evaluate the pandemic's impact on observed trends. Second, due to the partial release of data for 2021-2023, we could not analyze the following metabolic biomarkers, such as triglycerides, low-density lipoprotein cholesterol, glomerular filtration rate, and C-reactive protein. Finally, NHANES response rates have declined over time. To mitigate nonresponse bias, we incorporated survey weights provided by the National Center for Health Statistics 26 . Conclusion In this cross-sectional study, trends in cardiovascular and diabetes-related metabolic biomarkers were analyzed from 2013 to 2023. We identified variations in these biomarkers across subgroups defined by age, gender, race, income, and education level. Our findings offer insights for shaping prevention policies, particularly by addressing the needs of diverse populations. Such policies could contribute to a more equitable society, where everyone has the opportunity to reduce their risk of cardiovascular disease and diabetes.

We observed an upward trend in most biomarkers, including BMI, waist circumference, BF%, DBP, ePWV, fasting glucose, and glycohemoglobin, while pulse rate showed a declining trend. Peak values for BMI, waist circumference, and fasting glucose were reached in the 2017-2020 cycle, while body fat, DBP, and ePWV continued to rise in the 2021-2023 cycle. Trends varied across different population subgroups, with education and income identified as significant subgroup characteristics. BMI, waist circumference, BF%, SBP, ePWV, and glycated hemoglobin showed differences between these subgroups. Differences in pulse rate, total cholesterol, and HOMA-IS were noted between older and younger groups. Variations in SBP were also observed across racial groups; although these differences were not mirrored in fasting glucose and glycohemoglobin, both biomarkers significantly increased in the Mexican American subgroup.\u003c/p\u003e\n\u003cp\u003eWe first assessed trends in BMI, waist circumference, and BF%, as these three indicators are commonly used to evaluate an individual\u0026apos;s cardiometabolic risk. BMI is strongly associated with an increased risk of CVD and diabetes. Compared with individuals of normal weight, competing hazard ratios for incident CVD were 1.21 (95% CI: 1.14-1.28) and 1.32 (95% CI: 1.24-1.40) among overweight men and women (BMI, 25.0-29.9 kg/m\u003csup\u003e2\u003c/sup\u003e), respectively\u003csup\u003e28\u003c/sup\u003e. Lifetime diabetes risk at age 18 rose from 7.6% to 70.3% among men and from 12.2% to 74.4% among women between underweight and severely obese (BMI \u0026gt;35 kg/m\u003csup\u003e2\u003c/sup\u003e) categories\u003csup\u003e29\u003c/sup\u003e. However, the limitations of BMI in fully capturing cardiometabolic risk are partly due to its inadequacy as a standalone biomarker for abdominal adiposity\u003csup\u003e30\u003c/sup\u003e. Waist circumference, which is simple to standardize clinically, provides a straightforward measure of abdominal adiposity and is strongly associated with all-cause mortality\u003csup\u003e31\u003c/sup\u003e.\u003c/p\u003e\n\u003cp\u003eAdditionally, we assessed BF%, which reflects body composition more accurately than BMI and demonstrates stronger associations with cardiometabolic conditions\u003csup\u003e32\u003c/sup\u003e. Notably, a longitudinal study reported a statistically significant change in total fat percentage before and after the COVID-19 pandemic\u003csup\u003e33\u003c/sup\u003e. The observed subgroup differences in these three biomarkers align with previous studies. For example, a multi-round survey of California adults from 2011 to 2014 indicated an inverse relationship between obesity and household income\u003csup\u003e34\u003c/sup\u003e. Furthermore, BMI and waist circumference were significantly lower across all three higher education categories (vocational secondary, other secondary, and university degree) compared to the lowest education level\u003csup\u003e35\u003c/sup\u003e. Our findings suggest an upward trend in these three biomarkers over the past decade, with low-income and low-education populations being particularly vulnerable.\u003c/p\u003e\n\u003cp\u003eWe subsequently conducted a trend analysis of cardiovascular physical examination indicators, including SBP, DBP, pulse rate, and ePWV. Our findings indicate that SBP levels remained well-controlled with no significant upward trend; however, DBP levels showed a marked increase. A comparative study on the impact of systolic and diastolic blood pressures on cardiovascular outcomes found that both SBP and DBP independently contribute to adverse cardiovascular events. In survival models, continuous systolic hypertension (\u0026ge;140 mmHg) was associated with a hazard ratio per unit increase in z-score of 1.18 (95% CI: 1.17-1.18), while diastolic hypertension (\u0026ge;90 mmHg) had a hazard ratio of 1.06 (95% CI: 1.06-1.07)\u003csup\u003e36\u003c/sup\u003e. Additionally, the study demonstrated a \u0026quot;J\u0026quot;-shaped relationship between DBP and cardiovascular outcomes, suggesting that both excessively high and low DBP levels may increase the risk of adverse cardiovascular events\u003csup\u003e36\u003c/sup\u003e. Consequently, while elevated DBP in our study may not directly raise cardiovascular event risk, suggesting more robust SBP-lowering strategies that can avoid significant DBP reduction. ePWV, a marker of arterial stiffness reflecting arterial health and aging, was calculated from age and mean BP using an equation from the Reference Values for Arterial Stiffness Collaboration\u003csup\u003e37\u003c/sup\u003e. ePWV is predictive of mortality and cardiovascular risk, correlating with all-cause mortality (HR per 1 m/s increase, 1.13; 95% CI: 1.05-1.21) and myocardial infarction (HR per 1 m/s increase, 1.23; 95% CI: 1.09-1.39)\u003csup\u003e38\u003c/sup\u003e.

This study aimed to assess trends in cardiovascular and diabetes-related metabolic biomarkers among U.S. adults from 2013-2014 to 2021-2023.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eDESIGN, SETTING, AND PARTICIPANTS\u003c/strong\u003e This study analyzed five cycles of cross-sectional data from the National Health and Nutrition Examination Survey (NHANES) spanning 2013-2014 to 2021-2023. The sample was weighted to reflect the noninstitutionalized civilian U.S. population aged 18 and older. Data analysis was conducted from August to October 2024.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eEXPOSURES\u003c/strong\u003e Calendar year and sociodemographic subgroups, including age, gender, race, educational level, and family poverty-to-income ratio.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eMAIN OUTCOMES AND MEASURES\u003c/strong\u003e Primary outcomes included body mass index (BMI), waist circumference, body fat percentage, systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse rate, estimated pulse wave velocity (ePWV), fasting glucose, glycohemoglobin, total fasting cholesterol, high-density lipoprotein cholesterol (HDL-C), fasting insulin, and insulin resistance index. Trends were estimated using survey-weighted linear regression models.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eRESULTS\u003c/strong\u003e A total of 10,337 participants were included. BMI, waist circumference, and body fat percentage showed significant increases (all \u003cem\u003eP\u003c/em\u003e for trend \u0026lt; 0.05). Specifically, BMI increased from 28.54 kg/m² (95% CI: 28.18-28.91) to 29.43 kg/m² (95% CI: 28.85-30.01); waist circumference rose from 97.63 cm (95% CI: 96.86-98.40) to 100.11 cm (95% CI: 98.77-101.44); and body fat percentage increased from 33.59% (95% CI: 31.11-34.07%) to 35.68% (95% CI: 34.90-36.46%). Significant interactions for these biomarkers were observed among various education and income subgroups. DBP (\u003cem\u003eP\u003c/em\u003e \u0026lt; 0.0001) and ePWV (\u003cem\u003eP\u003c/em\u003e \u0026lt; 0.0001) also increased, with DBP rising from 68.01 mmHg (95% CI: 67.42-68.60) to 74.17 mmHg (95% CI: 73.29-76.06) and ePWV from 7.89 m/s (95% CI: 7.75-8.02) to 8.41 m/s (95% CI: 8.27-8.55), while pulse rate declined from 72.27 bpm (95% CI: 71.17-73.37) to 70.59 bpm (95% CI: 69.96-71.23) (\u003cem\u003eP\u003c/em\u003e \u0026lt; 0.0001). Although SBP did not show an overall significant trend, increases were observed among men (from 121.06 mmHg [95% CI: 119.87-122.25] to 123.27 mmHg [95% CI: 122.41-124.12], \u003cem\u003eP\u003c/em\u003e for trend = 0.005) and individuals with less than a high school education (from 117.56 mmHg [95% CI: 115.77-119.34] to 124.55 mmHg [95% CI: 121.81-127.30], \u003cem\u003eP\u003c/em\u003efor trend \u0026lt; 0.0001). No significant trends were found for total cholesterol and HDL-C. Fasting glucose and glycohemoglobin showed significant upward trends (P for trend = 0.001 and 0.027, respectively), with notable increases in Mexican Americans (fasting glucose: 5.90 mmol/L [95% CI: 5.81-6.00] to 6.64 mmol/L [95% CI: 6.26-7.01], \u003cem\u003eP\u003c/em\u003e for trend \u0026lt; 0.0001; glycohemoglobin: 5.59% [95% CI: 5.51-5.68] to 6.06% [95% CI: 5.84-6.28], \u003cem\u003eP\u003c/em\u003e for trend \u0026lt; 0.001).\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eCONCLUSIONS AND RELEVANCE\u003c/strong\u003e Analysis of NHANES data indicates that most cardiovascular and diabetes-related metabolic biomarkers significantly increased from 2013-2014 to 2021-2023, with notable differences across demographic groups.
