[Factors associated with obesity in a sedentary activity user group at the Dantokpa market (Benin).]

To study obesity prevalence and associated factors in sedentary activity users at the Dantokpa market, Cotonou.

From October to November 2016, 460 subjects were selected by stratified survey. Anthropometric data and information regarding knowledge and practices of the subjects related to obesity were collected by a questionnaire. The factors associated with obesity were researched by a logistic regression model.

The obesity prevalence was 35.7%. It was more predominant in women (P < 0.0001) and those aged between 38-57 years (P < 0.0001). Insufficient or false knowledge and insufficient or bad practices concerning obesity cohabited among Dantokpa market sedentary users. The obesity associated factors were the sex (OR = 2.3; P < 0.006), the age of 38 to 57 years (2.3; P = 0.014), marital status (2.5; P = 0.003), knowledge of physical incapacity as a consequence of obesity (1.8; P < 0.0001), daily sedentary duration between three and seven hours (18.0; P < 0.0001) and more than seven hours (85.1; P < 0.0001), family childbirth circumstances (1.9; P = 0.002) revenue increasing circumstances (3.1; P = 0.001) and sleep duration (2.01; P = 0.003).

This study suggests the necessity for the implementation of strategies including notably physical activities and knowledge about obesity in order to reduce obesity prevalence in Dantokpa market sedentary activity users.
