Abstract
in English, Portuguese

Vulnerable population groups, including people living with HIV/Aids (PLHA), may have a high prevalence of food insecurity (FI). A cross-sectional study evaluated the internal validity of the Brazilian Food Insecurity Scale (Escala Brasileira de Insegurança Alimentar - EBIA) and measured the prevalence of FI in a sample of 796 PLHA in João Pessoa, Paraíba State (PB). The validation was performed using a Rasch analysis. The association of FI with sociodemographic and clinical characteristics was assessed using the chi-square test. Associated variables were included in a Poisson multiple regression model. The EBIA was valid for PLHA with fit values within the expected limits and item severity conforming to the theoretical model. The EBIA identified 66.5% of PLHA with FI in the sample (30.8% mild FI, 18.1% moderate FI and 17.6% severe FI). Moderate FI and severe FI were associated with an age younger than 43 years (prevalence ratio (PR) = 1.49; 95% confidence interval (CI): 1.14-1.86), primary education (PR=1.64; 95% CI: 1.24-2.17), income per capita lower than ½ minimum wage (MW) (PR=1.83; 95% CI: 1.37-2.44), lack of occupation (PR=1.59; 95% CI: 1.16-2.19) and adult-only households with a female reference person (PR=2.19; 95% CI: 1.45-3.31). The PLHA in this study had a high prevalence of FI, worsening their living conditions and potentially exacerbating their health problems.

Resumo Grupos populacionais vulneráveis, como pessoas vivendo com HIV/Aids (PVHA), podem ter alta prevalência de Insegurança Alimentar (IA). Estudo seccional avaliou a validade interna da escala EBIA e mediu a prevalência de IA em amostra de 796 PVHA em João Pessoa (PB). A validação foi feita por análise de Rasch. Testou-se a associação da insegurança alimentar com características sociodemográficas e clínicas com o teste qui-quadrado. Variáveis associadas foram incluídas em um modelo de regressão múltipla de Poisson. EBIA apresentou validade em PVHA com ajuste dentro dos limites esperados e severidade dos itens respeitando o modelo teórico e identificou 66,5% de IA na amostra (30,8% IA leve, 18,1% IA moderada e 17,6% IA grave). Insegurança alimentar moderada ou grave estiveram associadas à idade menor que 43 anos (RP = 1,49; IC95%: 1,14 – 1,86), escolaridade fundamental (RP = 1,64; IC95%: 1,24 – 2,17), renda per capita menor que ½ salário mínimo (RP = 1,83; IC95%: 1,37 – 2,44), falta de ocupação (RP = 1,59; IC95%: 1,16 – 2,19) e domicílios compostos somente por adultos com a pessoa de referência do sexo feminino (RP = 2,19; IC95%: 1,45 – 3,31). As PVHA estudadas apresentam alta prevalência de IA piorando suas condições de vida podendo agravar os problemas de saúde vivenciados por este grupo.
