[Intra-urban differences in vulnerability among the elderly population].

Area of Science:

• Gerontology
• Public Health
• Urban Health

Context:

• Intra-urban health disparities pose significant challenges for elderly populations.
• Accurate identification of vulnerable elderly individuals is crucial for targeted interventions.
• Existing vulnerability indices may not fully capture the complexities of urban aging.

Purpose:

• To evaluate the adequacy of a health vulnerability index (HVI) for identifying intra-urban differences in vulnerability among the elderly.
• To assess the association between HVI-defined risk levels and various environmental, health, and service-related factors.
• To determine the utility of the HVI as an instrument for healthcare planning.

Summary:

• A health vulnerability index (HVI) was developed using socioeconomic and mortality data at the census tract level.
• 1,055 elderly residents (aged 60+) in Belo Horizonte, Brazil, were sampled, and their households classified as low, medium, or high-risk based on HVI.
• Multivariate analysis revealed significant associations between household risk level and social/physical environment, health status, behaviors, and service needs.

Impact:

• The HVI demonstrates utility in identifying varying levels of vulnerability within an urban elderly population.
• Findings support the HVI as a valuable tool for local health authorities to address specific needs of older adults.
• This research contributes to the development of more precise public health strategies for aging populations in urban settings.
