Claim 1 of 6Not coveredA CDC-published study using 2025 Youth Risk Behavior Survey data assessed cardiovascular health among U.S. high school students.View evidenceHide evidence

Why this verdict

The abstract-level profile supports that the study used nationally representative 2025 YRBS data to assess cardiovascular health among U.S. high school students using constructed CVH scores. However, the supplied abstract profile does not verify the article’s framing that it was specifically “CDC-published,” so that part is not verifiable at this depth.

1

Study evidence

Mean overall CVH score among U.S. high school students (2025 YRBS, complete-case n=5,192) was 65.3.65.3 (mean)

“data from the nationally representative 2025 Youth Risk Behavior Survey (YRBS) of U.S. high school students were used to calculate scores for five metrics of CVH”
Claim 2 of 6Not coveredOverall cardiovascular health scores were lower among females, students in grades 10–12, and Black or Hispanic students compared with some other groups.View evidenceHide evidence

Why this verdict

The profile supports lower mean overall CVH among females versus males, lower scores in grades 10–12 compared with grade 9, and lower scores among Black or African American students compared with most other racial/ethnic groups. However, the abstract-level profile does not provide the Hispanic-student comparison stated in the story, so the full claim is not verifiable at this depth.

Study evidence

Overall CVH score was lower among female than male students.64.2 (female) vs 66.2 (male)

“Weighted mean scores and the prevalence of high (80-100), moderate (50-79), and low (0-49) scores were estimated overall and by sex, grade, and race and ethnicity.”
2

Study evidence

Overall mean CVH score was 65.3; 20.7% of students had high (80–100), 61.3% had moderate (50–79), and 18.0% had low (0–49) overall CVH scores.Mean=65.3; High=20.7%; Moderate=61.3%; Low=18.0%

“For the CVH metrics, mean scores were highest for BMI (85.4, reflecting lower BMI) and nicotine exposure (80.5, reflecting lower exposure), and lowest for diet (39.3), sleep health (59.1), and physical activity (62.0).”
Claim 3 of 6Not coveredBecause the survey was cross-sectional and relied on self-reported measures, the article says grade comparisons cannot establish change over time and the findings do not amount to a full clinical assessment of cardiovascular health.View evidenceHide evidence

Why this verdict

The abstract-level profile supports that the analysis is descriptive and based on a single cross-sectional survey year, so temporal or causal interpretations such as individual change over time are not established. It also supports that only five LE8-aligned metrics were used. However, the supplied profile does not explicitly verify all parts of the story caveat, including self-report bias and the statement that the score is not a full clinical assessment, so the full claim is not verifiable at abstract depth.

Claim 4 of 6SupportedThe researchers found that approximately four in five students had low or moderate scores on the five assessed cardiovascular health measures.View evidenceHide evidence

As statedapproximately four in five; around 80%

Why this verdict

The paper profile reports 20.7% high, 61.3% moderate, and 18.0% low overall CVH. Low plus moderate equals 79.3%, matching the story’s “approximately four in five” or around 80% framing.

Claim 5 of 6SupportedThe five assessed metrics were physical activity, diet, sleep health, BMI, and nicotine exposure, aligned with the American Heart Association’s LE8 scoring system, while blood pressure, glucose, and lipid levels were not measured.View evidenceHide evidence

Why this verdict

The profile states that five Life’s Essential 8–aligned metrics were scored: diet, physical activity, nicotine exposure, sleep health, and BMI. Because the profile identifies only these five LE8-aligned metrics as assessed, the story’s statement that blood pressure, glucose, and lipids were not measured is consistent with the abstract-level evidence.

What the story left out

Important study details the story did not include.

  • The profile notes that the abstract does not report measures of statistical uncertainty, such as confidence intervals, p-values, or tests for the stratified demographic estimates.

    The story caveats listed do not mention the absence of uncertainty estimates or formal statistical testing in the abstract-level evidence, which is relevant when interpreting subgroup comparisons.

9 things the story did carry across
  • The study’s central contribution was a secondary analysis of nationally representative 2025 YRBS data among U.S. high school students, constructing five 0–100 CVH metric scores and averaging them into an overall CVH score.
  • The five assessed CVH metrics were diet, physical activity, nicotine exposure, sleep health, and BMI, aligned with the AHA Life’s Essential 8 framework.
  • The abstract reports the overall CVH distribution: 20.7% high, 61.3% moderate, and 18.0% low, meaning about four in five students had low or moderate overall CVH.
  • The mean overall CVH score was 65.3, and component means were highest for BMI and nicotine exposure and lowest for diet, with sleep and physical activity also less favorable than BMI and nicotine exposure.
  • The paper reports descriptive demographic differences in overall CVH by sex, grade, and race/ethnicity: lower among females than males, lower in grades 10–12 than grade 9, higher among Asian students, and lower among Black or African American students compared with most other groups.
  • The paper’s discussion frames the findings as identifying opportunities for school and community programs to promote healthier behaviors, especially diet, sleep, and physical activity.
  • The analysis was restricted to students with complete data, with the abstract-level profile reporting n=5,192 complete cases.
  • The findings are descriptive estimates from a single cross-sectional survey year, so temporal or causal inferences are not established.
  • Only five LE8-aligned components were assessed; the profile does not present a full eight-component clinical cardiovascular health assessment.

In plain English

Secondary analysis of nationally representative 2025 YRBS data constructs five CVH metric scores (diet, physical activity, nicotine exposure, sleep health, BMI; each 0–100), averages them to produce an overall CVH score, and reports weighted mean and categorical prevalence (high 80–100; moderate 50–79; low 0–49) among students with complete data (n=5,192).

Key findings

  • Mean overall CVH score among U.S. high school students (2025 YRBS, complete-case n=5,192) was 65.3.65.3 (mean)
  • Distribution of overall CVH categories: 20.7% high (80–100), 61.3% moderate (50–79), 18.0% low (0–49).20.7% high; 61.3% moderate; 18.0% low

In plain English

Survey-weighted, stratified estimates from the 2025 YRBS show differences in the constructed overall CVH score and the prevalence of score categories (high/moderate/low) by sex, grade, and race/ethnicity: mean overall CVH was lower in female versus male students, declined with increasing grade, and was higher among Asian and lower among Black or African American students; similar patterns were reported for prevalence of high overall CVH scores.

Key findings

  • Overall CVH score was lower among female than male students.64.2 (female) vs 66.2 (male)
  • Overall CVH score decreased with increasing grade level.Grade 9 = 68.3; Grade 10 = 65.9; Grade 11 = 63.7; Grade 12 = 62.7
“Weighted mean scores and the prevalence of high (80-100), moderate (50-79), and low (0-49) scores were estimated overall and by sex, grade, and race and ethnicity.”

In plain English

Analysis of nationally representative 2025 YRBS data (n=5,192 with complete data) produced five 0–100 component CVH metric scores (diet, physical activity, nicotine exposure, sleep health, BMI) and an averaged overall CVH score. Mean component scores were highest for BMI and nicotine exposure and lowest for diet, with sleep and physical activity intermediate; these component patterns contributed to a moderate mean overall CVH score and to demographic differences by sex, grade, and race/ethnicity.

Key findings

  • Overall mean CVH score was 65.3; 20.7% of students had high (80–100), 61.3% had moderate (50–79), and 18.0% had low (0–49) overall CVH scores.Mean=65.3; High=20.7%; Moderate=61.3%; Low=18.0%
  • Among component metrics, mean scores were highest for BMI (85.4) and nicotine exposure (80.5).BMI mean=85.4; Nicotine exposure mean=80.5
“For the CVH metrics, mean scores were highest for BMI (85.4, reflecting lower BMI) and nicotine exposure (80.5, reflecting lower exposure), and lowest for diet (39.3), sleep health (59.1), and physical activity (62.0).”
