Until now, prospective studies of aging have begun with 50- to 60-year olds, not adolescents. Premature deaths, childhood variables, and alcohol abuse have been often ignored. So has positive aging. As people live longer, gerontology needs to understand the determinants of health as well as illness in the later years.
The present study follows a cohort of adolescent boys (332 inner-city youths) for 60 years or until death. Complete physical exams were obtained every 5 years and psychosocial data every 2 years. Predictor variables assessed prior to age 50 include six variables reflecting uncontrollable factors--parental social class, environmental strengths, number of family problems, major depression, ancestral longevity, and premorbid physical health at age 50--and six variables reflecting (at least some) personal control: alcohol abuse, smoking, marital stability, body mass index, coping mechanisms, and education. The four outcome variables chosen to assess healthy aging at 70 reflected both "mind" and "body." They included objectively assessed variables (death and/or disability prior to 70, and objective mental health) and two subjectively assessed variables (perceived instrumental activities of daily living and life enjoyment).
Multivariate analysis suggested that positive aging at 70 could be predicted by variables assessed prior to age 50. More hopeful still, if the six variables under some personal control were controlled, depression was the only uncontrollable variable that affected the quality of subjective and objective aging.
First, we may have greater personal control over our biopsychosocial health after retirement than previously recognized. Second, in this cohort, psychiatric rather than sociological predictors appeared more important.
到目前为止,衰老的前瞻性研究始于50到60岁的人群,而非青少年。过早死亡、童年变量和酒精滥用常常被忽视。积极老龄化也是如此。随着人们寿命的延长,老年医学需要了解晚年健康和疾病的决定因素。
本研究对一组青春期男孩(332名城市青年)进行了60年的跟踪或直至其死亡。每5年进行一次全面体检,每2年收集一次社会心理数据。在50岁之前评估的预测变量包括六个反映不可控因素的变量——父母社会阶层、环境优势、家庭问题数量、重度抑郁、祖先寿命以及50岁时的病前身体健康状况——以及六个反映(至少部分)个人控制能力的变量:酒精滥用、吸烟、婚姻稳定性、体重指数、应对机制和教育程度。选择用来评估70岁时健康老龄化的四个结果变量反映了“身心”两方面。它们包括客观评估的变量(70岁之前的死亡和/或残疾,以及客观心理健康状况)和两个主观评估的变量(对日常生活工具性活动的感知和生活乐趣)。
多变量分析表明,70岁时的积极老龄化可以通过50岁之前评估的变量来预测。更令人欣慰的是,如果控制了六个在一定程度上受个人控制的变量,抑郁是唯一影响主观和客观老龄化质量的不可控变量。
第一,退休后我们对自身生物心理社会健康的个人控制可能比之前认为的更大。第二,在这个队列中,精神方面而非社会学方面的预测因素似乎更重要。
