This research aimed to identify colic associated factors in horses of military units in Rio de Janeiro State: Regimento Escola de Cavalaria, Academia Militar das Agulhas Negras and Esquadrão Escola de Cavalaria. A case control study nestled in one coorte was conducted. A total of 770 horses had been studied, with 362 (47.0%) horses classified as cases and 408 (53.0%) as control. Multivariable analysis of logistic regression was used to identify colic predictive factors, showing that horses confined system creation (OR= 3.62; 95% CI 2.57-5.10), concentrate intake above 6kg day-1 (OR= 2.64; 95% CI 1.54-4.50) and equine age, with higher possibility of colic in horses above 16 years (OR= 2.08; 95% CI 1.18-3.67), had been risk factors significantly associated with colic, after adjustment for other variables.
