健康预期寿命研究进展

近年来,随着老年人口的增多和寿命的延长,寿命中的生命质量日益成为社会关注的热点.之前用于评估人群健康状态和决定老龄人口政策制订所采用的指标是预期寿命(life expectancy),但预期寿命只能反映生命的数量,无法反映生命的质量.

The evolvement of health expectancy

Objective Studing the main influencing risk factors to provide evidence for improving the quality of life among people living with HIV. Methods The quality of life on 758 patients with HIV was evaluated by the Medical Outcomes Study Short-Form Health Survey (SF-36) and some potential risk factors as personal characteristics and disease condition were studied. Means and standard deviations of data were calculated and differences among groups and variances were tested using Student''s t test, followed by step-wise multivariate regression. Results The SF-36 two summary scores of 758 patients with HIV appeared to be 45.34±8.77 and 41.92±12.01 respectively. The physical component surmmary scores (PCS) had a gradual decrease with the increase of age. However, mental component summary scores (MCS) had a gradual decrease with the increase of time receiving the treatment. Male patients reported having a better quality of life (QOL) than female, and patients who were infected through injecting drug use and sexual transmission reported to have had better QOL than patients who were infected through paid blood plasma donation. Compare to patients having low CD4+ count, those having higher CD4+ count reported to have better QOL. Conclusion Patients being young, female, infected through paid blood plasma donation, having low CD4+ count, or treated for longer period, would have unsatisfactory QOL.
