Objective: to analyze the prevalence of abdominal obesity and associated factors in quilombola communities in Northern Minas Gerais, Brazil. Methods: cross-sectional study conducted in 2019 based on structured interviews and measurement of waist circumference; Poisson regression, separated by sex, was used to calculate prevalence ratios (PR) of abdominal obesity adjusted by independent variables and a 95% confidence interval (CI95%). Results: 56.6% (CI95% 50.9;62.0) had abdominal obesity. In the adjusted analysis, among men there was an association of the outcome with age ≥60 years (60-69 years: PR=2.52 – CI95% 1.33;4.75), non-smokers (PR=1.73 – CI95% 1.17;2.55), and hypertension (PR=1.42 – CI95% 1.11;1.80); in women, the outcome was associated with age ≥50 years (50-59 years: PR=1.25 – CI95% 1.01;1.54), ex-smokers (PR=1.26 – CI95% 1.00;1.58), consumption of chicken with skin (PR=1.09 – CI95% 1.00;1.19), and hypertension (PR=1.22 – CI95% 1.11;1.36). Conclusion: the prevalence of abdominal obesity was high among quilombolas, and it was higher in the elderly, hypertensive, smokers and ex-smokers.Objetivo: analisar a prevalência de obesidade abdominal e fatores associados em comunidades quilombolas do Norte de Minas Gerais, Brasil. Métodos: estudo transversal realizado em 2019, sobre entrevistas estruturadas e mensuração do perímetro da cintura; empregou-se regressão de Poisson, separada por sexo, para calcular razões de prevalências (RP) da obesidade abdominal ajustada pelas variáveis independentes e intervalo de confiança de 95% (IC95%). Resultados: 56,6% (IC95% 50,9;62,0) dos quilombolas observados apresentaram obesidade abdominal; na análise ajustada, entre homens, verificou-se associação do desfecho com idade de ≥60 anos (60-69 anos: RP=2,52 – IC95% 1,33;4,75), não ser tabagista (RP=1,73 – IC95% 1,17;2,55) e referir hipertensão arterial (RP=1,42 – IC95% 1,11;1,80), enquanto nas mulheres, associou-se com idade ≥50 anos (50-59 anos: RP=1,25 – IC95% 1,01;1,54), ex-tabagismo (RP=1,26 – IC95% 1,00;1,58), consumo de frango com pele (RP=1,09 – IC95% 1,00;1,19) e hipertensão (RP=1,22 – IC95% 1,11;1,36). Conclusão: encontrou-se prevalência de obesidade abdominal alta entre os quilombolas, maior nos idosos, hipertensos, fumantes e ex-fumantes
