BACKGROUND
Previous literature has explored the relationship between television viewing and cardiovascular disease (CVD) in adults; however, there remains a paucity of longitudinal data describing how young adult television viewing relates to premature CVD events.
OBJECTIVE
To ascertain the relationship between level and annualized changes in television viewing from young adulthood to middle age and the incidence of premature CVD events before age 60.
DESIGN
The Coronary Artery Risk Development in Young Adults (CARDIA) study, a prospective community-based cohort with over 30 years of follow-up (1985-present).
PARTICIPANTS
Black and White men and women who were 18-30 years old at baseline (1985-1986).
MAIN MEASURES
Independent variables: Individualized television viewing trajectories were developed using linear mixed models.
DEPENDENT VARIABLES
Fatal and nonfatal coronary heart disease (CHD), heart failure, and stroke outcomes were analyzed separately and as a combined CVD event outcome.
KEY RESULTS
Among 4318 included participants, every 1-h increase in daily hours of television viewing at age 23 was associated with higher odds of incident CHD (adjusted odds ratio [AOR] 1.26, 95% confidence interval [CI] 1.06-1.49) and incident CVD events (AOR 1.16, 95% CI 1.03-1.32). Each additional hour of daily television viewing annually was associated with higher annual odds of CHD incidence (AOR 1.55, 95% CI 1.06-2.25), stroke incidence (AOR 1.58, 95% CI 1.02-2.46), and CVD incidence (AOR 1.32, 95% CI 1.03-1.69). Race and sex modified the association between television viewing level at age 23 and CHD, heart failure, and stroke, with White men most consistently having significant associations.
CONCLUSIONS
In this prospective cohort study, greater television viewing in young adulthood and annual increases in television viewing across midlife were associated with incident premature CVD events, particularly CHD. Young adulthood as well as behaviors across midlife may be important periods to promote healthy television viewing behavior patterns.
背景
先前的文献探讨了成年人看电视与心血管疾病（CVD）之间的关系，但仍缺乏描述年轻人看电视与早发性 CVD 事件之间关系的纵向数据。
目的
确定从年轻到中年期间看电视的水平和年化变化与 60 岁前发生早发性 CVD 事件的关系。
设计
冠状动脉风险发展在年轻人（CARDIA）研究，一个具有 30 多年随访（1985 年至今）的前瞻性社区为基础的队列。
参与者
基线时年龄在 18-30 岁的黑人和白人男性和女性（1985-1986 年）。
主要措施
独立变量：使用线性混合模型制定个体化电视观看轨迹。
因变量
致命和非致命性冠心病（CHD）、心力衰竭和中风结局分别进行分析，并作为一个综合的 CVD 事件结局进行分析。
主要结果
在 4318 名纳入的参与者中，23 岁时每天看电视增加 1 小时与更高的 CHD 发病几率相关（调整后的优势比[OR]1.26，95%置信区间[CI]1.06-1.49）和 CVD 事件发病几率（OR 1.16，95%CI 1.03-1.32）。每年每天多看 1 小时电视与 CHD 发病率的年增长率更高（OR 1.55，95%CI 1.06-2.25）、中风发病率（OR 1.58，95%CI 1.02-2.46）和 CVD 发病率（OR 1.32，95%CI 1.03-1.69）相关。种族和性别改变了 23 岁时看电视水平与 CHD、心力衰竭和中风之间的关联，白人男性的关联最为显著。
结论
在这项前瞻性队列研究中，年轻成年人看电视较多，以及中年期间看电视的年化增加与早发性 CVD 事件的发生有关，尤其是 CHD。年轻成年人以及中年期间的行为可能是促进健康的电视观看行为模式的重要时期。
