To examine whether people who expect to live longer engage in healthier behaviors relative to people who expect to live shorter lives.
Patients (994 black Americans, 373 white Americans) from a publicly funded clinic estimated their expected survival age and reported their health behaviors (alcohol, tobacco, and drug use; sexual behaviors; physical activity; and sleep).
Subjective life expectancy (SLE) was a significant predictor of health behavior for both men and women. Race moderated the SLE-health behavior relation but only for alcohol and tobacco use.
Future research should explore the potential health benefits of shifting SLE from a more limited to an expansive perspective.
研究预期寿命较长的人群相较于预期寿命较短的人群是否会采取更健康的行为。
来自一家公立诊所的患者（994名美国黑人、373名美国白人）估计了他们的预期生存年龄，并报告了他们的健康行为（饮酒、吸烟和吸毒情况；性行为；体育活动；以及睡眠）。
主观预期寿命（SLE）是男性和女性健康行为的重要预测指标。种族调节了SLE与健康行为之间的关系，但仅适用于饮酒和吸烟行为。
未来的研究应探讨将SLE从更有限的视角转变为更广阔视角可能带来的健康益处。
