This study examined the cross-sectional and longitudinal associations of cardiorespiratory fitness (CRF) and ideal cardiovascular health (CVH).
CRF and the 7 CVH components were measured in 11,590 (8865 males; 2725 females) adults at baseline and in 2532 (2160 males; 372 females) adults with at least one follow-up examination from the Aerobics Center Longitudinal Study. Ideal CVH score was calculated as a composite of 7 measures, each scored 0 to 2. CVH groups were based on participant point score: ≤7 (poor), 8 to 11 (intermediate), and 12 to 14 (ideal). Analyses included general linear, logistic regression, and linear mixed models.
At baseline, participants in the high CRF category had 21% and 45% higher mean CVH scores than those in the moderate and poor CRF categories (P < .001). The adjusted odds (95% confidence interval) of being in the poor CVH group at baseline were 4.9 (4.4-5.4) and 16.9 (14.3-19.9) times greater for individuals with moderate and low CRF, respectively, compared with those with high CRF (P < .001). Longitudinal analysis found that for every 1-minute increase in treadmill time, CVH score increased by 0.23 units (P < .001) independent of age, sex, exam number, and exam year.
Higher CRF is associated with better CVH profiles, and improving CRF over time is independently associated with greater improvements in CVH.
本研究探讨了心肺适能（CRF）和理想心血管健康（CVH）的横断面和纵向关联。
在基线时，对 11590 名成年人（8865 名男性；2725 名女性）和至少有一次随访检查的 2532 名成年人（2160 名男性；372 名女性）测量了 CRF 和 7 项 CVH 成分。理想 CVH 评分是由 7 项指标的综合评分计算得出，每项指标评分范围为 0 到 2 分。CVH 组基于参与者的得分：≤7（差）、8 到 11（中等）和 12 到 14（理想）。分析包括一般线性、逻辑回归和线性混合模型。
在基线时，高 CRF 组的参与者 CVH 评分比中低 CRF 组分别高出 21%和 45%（P<0.001）。与高 CRF 组相比，中低 CRF 组个体在基线时处于较差 CVH 组的调整后比值比（95%置信区间）分别为 4.9（4.4-5.4）和 16.9（14.3-19.9）（P<0.001）。纵向分析发现，跑步机时间每增加 1 分钟，CVH 评分增加 0.23 分（P<0.001），与年龄、性别、检查次数和检查年份无关。
较高的 CRF 与更好的 CVH 特征相关，随着时间的推移改善 CRF 与 CVH 的改善独立相关。
