Predictors of dropout in the school-based multi-component intervention, ‘Mexa-se’

Abstract

To identify the predictors of dropout in the 'Mexa-se' intervention according to the body mass index (BMI) category. This was a controlled, non-randomized study. The intervention included: (i) increase in the intensity of physical activities (PA) in physical education (PE) classes; (ii) active recess; (iii) educational sessions on PA, nutrition and body image; and (iv) educational materials. Dropout was considered when students dropped out of intervention, or did not reach 75% attendance in PE classes. The independent variables were gender, age, study period, socioeconomic status, BMI, PA, screen time, food consumption, health perception, attitudes toward PA, self-efficacy for PA, perception of the school environment, body image and self-esteem. Binary logistic regression analysis was used. The dropout rate was 26.8%. In the total sample and among students with an adequate BMI, there was a greater probability of dropout with an increase in age. For overweight students, increased age and socioeconomic status, and studying in the afternoon period were predictors of dropout from the intervention. Socio-demographic factors were predictors of dropout from the 'Mexa-se' intervention; the associated factors differed based on the BMI category.

Health Literacy in Schools? A Systematic Review of Health-Related Interventions Aimed at Disadvantaged Adolescents

“…The adolescents, parents and program implementers described benefits across seven main areas, including dancing and related skills, behaviours (e.g., reduced television viewing), physical well-being, psychological well-being, relationships, respect for others and for diversity, and school performance. A PA, diet and mental health intervention assessed predictors to dropout in the 'Mexa Se' intervention [79]. It was reported that in the intervention group, age, body mass, height and BMI were all significant predictors of drop out.…”

“…Berria et al [79] To In the crude analysis for the entire sample and among students with adequate BMI at baseline, there was a greater probability of dropping out with increasing age and BMI. Students classified as overweight were more likely to drop out with increasing age.…”

“…The study characteristics are summarised in Table 1 below. Among the 41 studies, 22 were based in the United States , six in Australia [70][71][72][73][74][75], four in Brazil [76][77][78][79], two in Sweden [80,81], two in India [82,83] and one each in Belgium [84], Chile [85], Spain [86] and Canada [87]. The year of publication ranged from 1996 [59] to 2020 [76], with the majority published in the last decade (n = 35).…”

“…The year of publication ranged from 1996 [59] to 2020 [76], with the majority published in the last decade (n = 35). A total of 22 studies were randomised controlled trials (RCTs) [47,48,51,52,55,58,59,63,67,68,[70][71][72][73][74][75][76][77][78]82,85,86], ten employed pre-test-post-test quasi-experimental designs [49,53,62,[64][65][66]69,79,80,84], four employed a single group pretest-post-test designs [54,56,61,83], three were post-test qualitative evaluations [57,81,87], and the remaining two adopted cross-sectional designs [50,60]. All studies assessed the interventions using quantitative techniques, with the exception of five which employed mixed methods [49,54,69,…”

“…The largest group of interventions focused on PA and diet (n = 13) [49,55,[64][65][66][67][69][70][71]77,81,84,86], followed by PA (n = 8) [47,48,58,61,[73][74][75][76]80] and mental health (n = 7) [51,53,56,72,82,83,85]. The remainder targeted diet (n = 4) [54,60,62,78]; substance abuse (n = 2) [50,68]; PA, diet, substance abuse and mental health [59]; mental health and sleep [64]; PA, diet and substance abuse [52]; Sleep [57]; mental health and PA [87] and PA, diet and mental health [79]. Interventions were delivered by a wide range of people.…”
