我们回顾了近年来老龄化纵向研究的进展，重点是威斯康星州纵向研究（WLS）和健康与退休研究（HRS）。这两项研究都是生物社会调查趋势的一部分，其中生物测量与传统的调查技术相结合，以及跨研究更大协调的相关趋势。这两项研究都收集了DNA样本，并正在努力进行基因分型，以便进行广泛的关联研究。越来越多的关注心理测量的个性和认知能力，使用自适应测试结构也被共享的研究。HRS已将其经济计量扩展到消费的纵向研究以及养老金和社会保障财富的更广泛计量。它增加了心血管风险的生物标志物。WLS开发了一种综合方法来研究死亡和丧亲之痛，并创新地使用高中年鉴照片来捕捉参与者早期生活中的健康信息。
We review recent developments in longitudinal studies of aging, focusing on the Wisconsin Longitudinal Study (WLS) and the Health and Retirement Study (HRS). Both studies are part of a trend toward biosocial surveys in which biological measurement is joined with traditional survey techniques, and a related trend toward greater harmonization across studies. Both studies have collected DNA samples and are working toward genotyping that would allow broadly based association studies. Increased attention to psychological measurement of personality and of cognitive ability using adaptive testing structures has also been shared across the studies. The HRS has expanded its economic measurement to longitudinal studies of consumption and to broader-based measurement of pension and Social Security wealth. It has added biomarkers of cardiovascular risk. The WLS has developed an integrated approach to the study of death and bereavement and an innovative use of high school yearbook photographs to capture information about health in early life of its participants.
