BackgroundChildhood obesity is an important health problem worldwide. In this context,
there is a need for the development and evaluation of innovative educational
interventions targeting prevention and formation of health habits.ObjectivesTo ascertain the impact of ludic workshops on children’s knowledge,
self-care, and body weight.MethodsThis was a randomized, clinical study with 79 students aged 7-11 years,
conducted from March to November 2012. Anthropometric measurements were
collected and two questionnaires (Typical Day of Physical Activities and
Food Intake, in Portuguese, and the CARDIOKIDS, a questionnaire of knowledge
about cardiovascular risk factors) were applied at baseline, at the end of
intervention, and three months thereafter. The intervention consisted of
eight playful workshops, which involved the presentation of a play.ResultsSeventy-nine students were randomized to the intervention (n = 40) or the
control group (n = 39). Mean age was 10.0 ± 1.1 years. After eight
weeks, the intervention group showed significant improvement in the
knowledge score (p < 0.001). There was an increase in physical activity
scores in both groups, but with no difference between the groups at the end
of intervention (p = 0.209). A reduction in the BMI percentile was observed
in the intervention group, but there was no significant statistical
difference between the two groups after the intervention.ConclusionsPlayful interventions may improve knowledge and physical activity levels in
children and, when combined with other strategies, may be beneficial to
prevent child obesity and improve self-care.
