There were evaluations before and after the intervention, it had demographic characteristics, lifestyle variables, self-efficacy measurements for physical activity and fruit and vegetables consumption; also, biochemical and anthropometric measures. Focus groups were used to identify facilitators and barriers at personal, family and work levels. <strong>Results</strong>: After the intervention, almost 25% of teachers increased their physical activity practices, as well as self efficacy for physical activity practice and fruits and vegetables consumption. The main barriers were a double work burden linked with feminine gender roles, limiting beliefs, and, lack of urgency in preventing diseases. <strong>Conclusions</strong>: The educational intervention contributed in increasing self-efficacy regarding eating fruit and vegetables and the practice of physical activity of participating teachers.&nbsp;</p> ER -
