The aim of this study is to increase our understanding of declining network size with aging by differentiating between processes of loss and gain and studying the associations with various health problems.
Six observations of the Longitudinal Aging Study Amsterdam (LASA) across a time period of 16 years are used to study detailed network changes in a large sample of Dutch older adults aged 55 to 85 at baseline.
Results from multilevel regression analyses show that network size declines with aging, in particular for the oldest old. The decline in network size is to a large degree due to a lack of replacement of lost relationships with new relationships. Results show differential effects of health.
The older old and people in poor health have limited possibilities to compensate for network losses and may have a serious risk of declining network size in later life.
本研究旨在通过区分损失和增益过程,并研究与各种健康问题的关联,来加深我们对网络规模随年龄增长而缩小的认识。
利用 16 年时间内的 6 次纵向老龄化研究阿姆斯特丹(LASA)的观察结果,对基线时年龄在 55 至 85 岁的大量荷兰老年成年人的详细网络变化进行研究。
多层次回归分析的结果表明,网络规模会随着年龄的增长而缩小,特别是对于最年长的老年人。网络规模的缩小在很大程度上是由于失去的关系没有被新的关系所取代。结果显示健康状况存在差异影响。
最年长的老年人和身体状况不佳的人弥补网络损失的可能性有限,他们在晚年可能面临网络规模严重缩小的风险。
