Thirteen impact studies (n = 1653 participants) were selected and showed evidence on metabolic parameters such as reducing blood pressure (7.6%); body mass index-BMI (7.6%); glycated haemoglobin-HbA1c (15.4%); resting heart rate (7.6%); increase in static balance increase on balance (7.6%) and reduced body weight (7.6%). Furthermore, specific findings on each intervention were demonstrated, such as diminished rates of relapse in substance users (7.6%); increased populational knowledge on chronic diseases (23%) associated with a decrease in the potential complications (7.6%), and a rise on treatment adhesion (7.6%); impact on the follow-up of pregnant patients (7.6%) and progress on oral hygiene (15.4%). Therefore, it was concluded that this intervention strategy demonstrated significant magnitude in reducing the progression and complication of the assessed disorders.
