Abstract

This study aims to measure and analyze population aging in Brazil by combining chronological age and characteristics of population subgroups according to geographic region and sex. Using these indicators, the study advances the application of the relative age concept based on a physiological indicator related to the aging process. The data analyzed were drawn from the 2015 Brazilian Longitudinal Study of Aging. Variables analyzed included age, sex, region of residence (North, Northeast, Central-West, Southeast, and South), handgrip strength, and body mass index. The results indicate that individuals in the North and Northeast experience faster functional aging according to relative age estimates based on handgrip strength. Among women in these regions, the gap between relative and chronological age reaches up to 9.3 years. These findings highlight regional inequalities in aging and support the use of relative age as a composite indicator for monitoring and planning health policies.

巴西的地区不平等和衡量人口老龄化的新方法。

本研究旨在根据地理区域和性别，结合实足年龄和人口亚群特征，测量和分析巴西的人口老龄化。利用这些指标，研究提出了基于与衰老过程相关的生理指标的相对年龄概念的应用。所分析的数据来自2015年巴西老龄化纵向研究。分析的变量包括年龄、性别、居住地区（北部、东北部、中西部、东南部和南部）、握力和体重指数。结果表明，根据握力估算的相对年龄，北方和东北地区个体的功能衰老速度更快。在这些地区的妇女中，相对年龄和实际年龄之间的差距高达9.3岁。这些调查结果突出了老龄化方面的区域不平等现象，并支持使用相对年龄作为监测和规划卫生政策的综合指标。

期刊介绍： Cadernos de Saúde Pública/Reports in Public Health (CSP) is a monthly journal published by the Sergio Arouca National School of Public Health, Oswaldo Cruz Foundation (ENSP/FIOCRUZ). The journal is devoted to the publication of scientific articles focusing on the production of knowledge in Public Health. CSP also aims to foster critical reflection and debate on current themes related to public policies and factors that impact populations'' living conditions and health care. All articles submitted to CSP are judiciously evaluated by the Editorial Board, composed of the Editors-in-Chief and Associate Editors, respecting the diversity of approaches, objects, and methods of the different disciplines characterizing the field of Public Health. Originality, relevance, and methodological rigor are the principal characteristics considered in the editorial evaluation. The article evaluation system practiced by CSP consists of two stages.
