Background The Life's Simple 7 (LS7) metric incorporates health behaviors (body mass index, diet, smoking, physical activity) and health factors (blood pressure, cholesterol, glucose) to estimate an individual's level of cardiovascular health. The association between cardiovascular health and incident hypertension is unresolved. Hypertension's threshold was recently lowered and it is unclear if better cardiovascular health is associated with lower risk of incident hypertension with the updated threshold or in a multirace cohort. We sought to assess the association between better LS7 score and risk of incident hypertension among Black and White adults using a 130/80 mm Hg hypertension threshold. Methods and Results We determined the association between LS7 metric and incident hypertension in the REGARDS (Reasons for Geographic and Racial Disparities in Stroke) study, including participants free of baseline hypertension (2003-2007) who completed a second visit between 2013 and 2016. Hypertension was defined as systolic/diastolic blood pressure ≥130/80 mm Hg or antihypertensive medication use. Each LS7 component was assigned 0 (poor), 1 (intermediate), or 2 (ideal) points. We generated a 14-point score by summing points. Among 2930 normotensive participants (20% Black, 80% White), the median (25th-75th percentiles) LS7 total score was 9 (8-10) points. Over a median follow-up of 9 years, 42% developed hypertension. In the fully adjusted model, each 1-point higher LS7 score had a 6% lower risk of incident hypertension (risk ratio, 0.94 per 1 point; 95% CI, 0.92-0.96). Conclusions Better cardiovascular health was associated with lower risk of incident hypertension using a 130/80 mm Hg hypertension threshold among Black and White adults.
“生命简单七要素”(LS7)指标纳入了健康行为(体重指数、饮食、吸烟、身体活动)和健康因素(血压、胆固醇、血糖)来评估个体的心血管健康水平。心血管健康与新发高血压之间的关联尚无定论。近期高血压的阈值有所降低,目前尚不清楚在更新后的阈值下,或者在多种族队列中,更好的心血管健康是否与更低的新发高血压风险相关。我们试图采用130/80 mmHg的高血压阈值评估黑人和白人成年人中更好的LS7评分与新发高血压风险之间的关联。
我们在REGARDS(卒中地理和种族差异原因)研究中确定了LS7指标与新发高血压之间的关联,研究对象包括2003年至2007年无基线高血压且在2013年至2016年期间完成第二次访视的参与者。高血压定义为收缩压/舒张压≥130/80 mmHg或使用抗高血压药物。每个LS7组成部分分别给予0分(差)、1分(中等)或2分(理想)。我们通过对各部分得分求和得出一个14分的总分。在2930名血压正常的参与者中(20%为黑人,80%为白人),LS7总分的中位数(第25-75百分位数)为9分(8-10分)。在中位随访9年期间,42%的人患上了高血压。在完全调整模型中,LS7评分每提高1分,新发高血压风险降低6%(风险比为每1分0.94;95%CI,0.92-0.96)。
在黑人和白人成年人中,采用130/80 mmHg的高血压阈值时,更好的心血管健康与更低的新发高血压风险相关。
