The ideal cardiovascular health behaviors (ICHB) have been associated with a subsequent positive health status in adults. However, evidence regarding blood pressure (BP) and ICHB in adolescents is scarce. The aim of this prospective cohort was to evaluate the impact of accumulation of ICHB on BP values in adolescents over two years.
This is a longitudinal analysis with 445 adolescents (232 girls) aged 12-18 years old. Resting blood pressure was measured at baseline and 2 years later, and ICHBs at baseline according to standard procedures. Based on the American Heart Association definition, the ICHB index was defined as a sum of meeting the ICHBs (from 0 to 4, where 4 would be the healthiest profile of all ICHBs) for a healthy diet, physical activity, smoking status and body mass index.
Adjusted means values (ANCOVA) of BP parameters through achievement of a greater number of (between 1-4) the ICHBs (adjusting for potential confounders, age, sex, pubertal stage and socioeconomic status) showed that, as increase the number of ICHB accumulated as a lower the BP levels [ICHB and SBP (F = 4.501, p = 0.004), DBP (F = 2.725, p = 0.044), pulse pressure (F = 4.004, p = 0.008), and rate pressure product (F = 2.866, p = 0.036)] over two years.
A lower number of ICHB (smoking status, body mass index, physical activity, and diet) during adolescence play a key role on blood pressure over two years. A higher number of ICHB is seen to be associated with a lower risk of short-term, hypertension.
理想的心血管健康行为（ICHB）与成年人的后续健康状况呈正相关。然而，关于青少年的血压（BP）和 ICHB 的证据很少。本前瞻性队列研究的目的是评估两年内 ICHB 积累对青少年血压值的影响。
这是一项纵向分析，纳入了 445 名年龄在 12-18 岁的青少年（232 名女孩）。在基线和 2 年后测量静息血压，并按照标准程序在基线时测量 ICHB。根据美国心脏协会的定义，ICHB 指数定义为满足 ICHB（从 0 到 4，其中 4 代表所有 ICHB 中最健康的特征）的健康饮食、身体活动、吸烟状况和体重指数的总和。
通过实现更多的 ICHB（调整潜在混杂因素，年龄、性别、青春期阶段和社会经济地位），调整后的 BP 参数平均值（ANCOVA）显示，随着 ICHB 积累数量的增加，BP 水平降低[ICHB 和 SBP（F=4.501，p=0.004），DBP（F=2.725，p=0.044），脉压（F=4.004，p=0.008）和心率血压乘积（F=2.866，p=0.036）]。
青少年时期 ICHB 数量较少（吸烟状况、体重指数、身体活动和饮食）在两年内对血压有重要影响。ICHB 数量较高与短期高血压风险降低有关。
