Ethnic Disparities in Nutritional Status among Older Adults: Evidence from the Survey of Health, Welfare and Aging (SABE) Ecuador

Abstract

This study aims to identify those populations that should be targeted by specific interventions. A cross-sectional design was utilized. Ordered logistic regression analysis was utilized to assess the association between ethnic identity and risk of malnutrition. Data were drawn from Ecuador's Survey of Health, Welfare and Aging (SABE). The final sample consisted of 4,572 people who were 60 years or older who were able to provide responses to the survey by themselves. Ethnic identity was categorized into four: indigenous, mestizo (Spanish and Indigenous mixed heritage), Afro-Ecuadorian/mulato, and other. Risk of malnutrition was measured using Mini Nutritional Assessment Short-Form (MNA-SF). A range of covariates were selected from three groups of factors: sociodemographic, health-related, and social network. Results revealed that the indigenous ethnicity was the only group who had significantly higher risk of malnutrition compared to mestizo even after controlling for a range of covariates including socio-economic status, health related factors, and social support. Findings suggest the existence of underlaying factors hindering the risk of malnutrition among indigenous older adults. Considering the information revealed by SABE, interventions and other strategies should be targeted and designed specifically accounting for the needs, preferences, and culture of the most vulnerable population.
