Resumo: | Objective: to model the proportion of obese adults on the African continent in 2016 using covariates. Method: beta regression model, the data set used in the study was collected on the World Health Organization (WHO) website, from 43 countries belonging to the African continent, divided into five regions of Africa. The variables used in the study were the proportion of obese adults (y) as the response variable, and the variables life expectancy at birth (in years) (x1) were used as explanatory variables. alcohol (registered per capita consumption) (x2); the prevalence of insufficient physical activity (x3); Africa regions (x4); mean BMI (x5); overweight among children (5-9 years old) (x6); and estimated prevalence of depression (x7). The analyzes were performed in the R software, using the betareg package. Results: The beta regression model with variable dispersion proved to be adequate. The covariates that influence the proportion of obese adults are life expectancy at birth (in years) (x1), the prevalence of insufficient physical activity (x3), mean BMI (x5), and overweight among children (5-9 years) (x6), for the mean model, and the covariates mean BMI (x5) and estimated prevalence of depression (x7), for the precision model. All covariates were significant at the 10% significance level. All covariates for the mean model, except x1, had a positive effect on the response variable (y), and in the precision model, both x5 and x7 had a negative effect. Final considerations: this study is expected to present an adequate approach for modeling data on the proportion of obese adults, the dissemination of the beta regression model, and the identification of risk factors for obesity. |

Método: modelo de regressão beta, o conjunto de dados utilizado no estudo foi coletado no site da Organização Mundial da Saúde (OMS), provenientes de 43 países pertencentes ao continente africano, divididos em 5 regiões da África. As variáveis utilizadas no estudo foram a proporção de adultos obesos (y) como variável resposta, e como variáveis explicativas foram utilizadas as variáveis expectativa de vida ao nascer (em anos) (x1); álcool (consumo per capita registrado) (x2); prevalência de atividade física insuficiente (x3); regiões da África (x4); IMC médio (x5); excesso de peso entre crianças (5-9 anos) (x6); e prevalência estimada de depressão (x7). As análises foram realizadas no software R, utilizando o pacote betareg. Resultados: O modelo de regressão beta com dispersão variável se mostrou adequado. As covariáveis que influenciam a proporção de adultos obesos são: a expectativa de vida ao nascer (em anos) (x1), prevalência de atividade física insuficiente (x3), IMC médio (x5), e excesso de peso entre crianças (5-9 anos) (x6), para o modelo da média, e as covariáveis IMC médio (x5) e prevalência estimada de depressão (x7), para o modelo da precisão. Todas as covariáveis, foram significativas ao nível de 10% de significância. Todas as covariáveis para o modelo da média, exceto x1, apresentaram efeito positivo sobre a variável resposta (y), e no modelo para a precisão tanto x5 quanto x7 apresentaram efeito negativo. Considerações finais: com este estudo espera-se apresentar uma abordagem adequada para modelagem de dados da proporção de adultos obesos, a divulgação do modelo de regressão beta e a identificação de fatores de risco para a obesidade.Universidade Federal de Santa Maria2024-02-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/revistasaude/article/view/7007510.5902/2236583470075Saúde (Santa Maria); Vol. 49 No. 2 (2023): Revista Saúde (Santa Maria) Ano 2023; e70075Saúde (Santa Maria); v. 49 n. 2 (2023): Revista Saúde (Santa Maria) Ano 2023; e700752236-58340103-4499reponame:Saúde (Santa Maria)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/revistasaude/article/view/70075/63289Copyright (c) 2024 Valentina Wolff Lirio, Laís Helen Loosehttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessLirio, Valentina WolffLoose, Laís Helen2024-03-08T17:46:37Zoai:ojs.pkp.sfu.ca:article/70075Revistahttps://periodicos.ufsm.br/revistasaudePUBhttps://periodicos.ufsm.br/revistasaude/oairevistasaude.ufsm@gmail.com || amanda.revsaude@gmail.com || beatriz.revsaude@gmail.com2236-58342236-5834opendoar:2024-03-08T17:46:37Saúde (Santa Maria) - Universidade Federal de Santa Maria (UFSM)false |
