Background
Little is known about the role of social class in the association between adiposity measures and self-rated health, and several studies have evaluated its influence as a confounder. The aim of the study is to investigate whether social class is an effect modifier in the association between adiposity measures and self-rated health in participants in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).
Method
Cross-sectional design, including 6453 men and 7686 women. Body mass index (kg/m
2
) and waist circumference (cms) were assessed. Self-rated health was categorized as good, fair and poor. Socio-occupational class was based on the participants’ occupation, education and per capita income. Multicovariate ordinal logistic model was used to evaluate the association between adiposity measures and self-rated health.
Results
For women, the low and medium socio-occupational class effects were higher for those with waist circumference between 80 and 88 cm or overweight. For men, the low and medium socio-occupational class effects were higher for those with adequate waist circumference or normal body mass index.
Conclusions
Social class is an effect modifier in the association between body mass index or waist circumference and self-rated health.
Background
Self-rated health (SRH) - one of the most common health indicators used to verify health conditions - can be influenced by several types of socioeconomic conditions, thereby reflecting health inequalities. This study aimed to evaluate the participant profiles regarding the association between self-rated health and social and occupational characteristics of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).
Methods
Cross-sectional design, including 11,305 individuals. Self-rated health was categorized as good, fair, and poor. The relationship between socio-demographic, psychosocial work environment, health-related variables, and self-rated health was analyzed by multiple correspondence analysis (stratified by age: up to 49 years old and 50 years old or more).
Results
For both age strata, group composition was influenced by socioeconomic conditions. Poor SRH was related to lower socioeconomic conditions, being women, black self-declared race/ethnicity, being non-married/non-united, low decision authority, low skill discretion, and obesity.
Conclusion
To promote health, interventions should focus on reducing existing socioeconomic, race, and gender inequalities in Brazil.
Introdução: A neoplasia maligna da próstata é o segundo tipo de câncer mais incidente entre os homens e, em 2012, foram estimados 1,1 milhão de casos novos e 300 mil mortes no mundo. Possíveis fatores de risco para ocorrência desse tipo de câncer são a idade e a história familiar. Objetivo: Analisar a tendência da mortalidade por câncer de próstata em Petrópolis, no período compreendido entre 1980 e 2012. Método: Foi realizado um estudo ecológico de série temporal. Os dados de mortalidade foram coletados do Sistema de Informação sobre Mortalidade do Ministério da Saúde (SIM/MS/DATASUS ) e os dados de população, do Instituto Brasileiro de Geografia e Estatística (IBGE). As taxas de mortalidade foram padronizadas por faixa etária, por método direto. Para avaliar a tendência temporal da mortalidade, foi utilizado o método de regressão de Prais-Winsten no qual as taxas de mortalidade padronizadas log-transformadas foram consideradas como variável dependente (y) e os anos analisados como variável independente (x). Resultados: A taxa média padronizada de mortalidade por câncer de próstata, correspondente ao período de 1980 a 2012, foi de 104,6 por 100 mil homens. A mortalidade, ao longo dos anos estudados, apresentou tendência crescente estatisticamente significativa (p<0,05), aumentando de 55,4, em 1980, para 114,3, em 2012. Conclusão: As tendências das taxas de mortalidade por câncer de próstata no município foram crescentes e significativas, o que remonta à necessidade de formulação de um diagnóstico regional, para elucidar as causas desse comportamento e propor estratégias de ação.
