To describe income-related inequalities in chewing ability of the elderly populations residing in different European countries.
This study investigates income-related inequalities on basis of cross-sectional data from the Survey of Health, Ageing and Retirement in Europe (SHARE Wave 2).
SHARE contains information on chewing abilities of 33,411 individuals aged 50+ from 14 different countries.
Income-related inequalities in chewing ability were identified by means of concentration indices (CI) and slope indices of inequality (SII).
Disproportionate concentration of chewing ability among the rich elderly populations was evident for all countries except Ireland (relative inequality according to CI). Moreover, chewing abilities were significantly better amongst individuals from the highest income groups, compared with the lowest, for all countries except Italy, Switzerland, Czechia, Poland and Ireland (absolute inequality according to SII). Denture status explained some proportion of absolute but not of relative inequalities.
There is considerable income-related inequality in chewing ability for several elderly populations residing in Europe.
描述居住在不同欧洲国家的老年人群咀嚼能力方面与收入相关的不平等情况。
本研究基于欧洲健康、老龄化与退休调查（SHARE第二轮）的横断面数据，调查与收入相关的不平等情况。
SHARE包含来自14个不同国家的33411名50岁及以上个体的咀嚼能力信息。
通过集中指数（CI）和不平等斜率指数（SII）确定咀嚼能力方面与收入相关的不平等情况。
除爱尔兰外，所有国家富裕老年人群中咀嚼能力的分布不均均很明显（根据CI得出的相对不平等情况）。此外，除意大利、瑞士、捷克、波兰和爱尔兰外，所有国家中，收入最高组个体的咀嚼能力明显优于收入最低组个体（根据SII得出的绝对不平等情况）。假牙佩戴情况解释了部分绝对不平等，但未解释相对不平等。
居住在欧洲的多个老年人群在咀嚼能力方面存在与收入相关的显著不平等。
