BACKGROUND : Evaluating the impact of a nutrition education program could provide
insight into the effectiveness of an intervention. Researchers tested the hypothesis that a
theory-based contextual nutrition education program (NEP) would improve the nutrition
knowledge, attitudes, and dietary practices (KAP) of teachers and learners.
METHODS : Twenty three teachers who taught nutrition in Grades 4–7 (treatment
school, n = 12) and 681 learners (treatment school, n = 350) participated in the
study. In this quasi-experimental study, two primary schools were randomly selected to
implement a contextual NEP. The nutrition KAP were assessed using previously validated
questionnaires. The treatment school teachers taught nutrition using a developed
nutrition education manual, while the control school teachers taught nutrition in the usual
manner. Random effects Generalized Least Squares regression estimated the difference
in the teachers’ and learners’ KAP for the treatment and control schools; p = 0.025 for
a one-tailed test.
RESULTS : At post-implementation, the treatment school teachers’ had higher total
nutrition knowledge mean score (85.5% ± 8.2, p = 0.003) compared to the control
school.Within the treatment school, total nutrition knowledgemean score of the teachers
improved by 14.1%, p ≤ 0.001. Learners in the treatment school had higher total nutrition
knowledge (53.2% ± 16.9, p = 0.002) and nutrition attitude (63.9% ± 19.7, p = 0.001)
scores compared to learners in the control school. Within the treatment school, learners’
total nutrition knowledge and nutrition attitudes scores increased by 4.9%, p ≤ 0.001 and
6.9%, p ≤ 0.001, respectively. The dietary practices of the teachers and the learners, and the nutrition attitudes of the teachers in the treatment school showed no significant within
school improvement or in comparison with the control school (p > 0.025).
CONCLUSIONS : The NEP led to the improvement in the teachers’ and the learners’
nutrition knowledge and the learners’ nutrition attitudes. However, no significant
improvement in the dietary practices of either teachers or learners was found.

We investigated the nutrition education (NE) practices of teachers of grade 4‒7 learners in 11 primary schools (85% of total number) of the Bronkhorstspruit district (Gauteng Province) to identify opportunities for improving ...
BACKGROUND : The increasing prevalence of being overweight and obesity in South African
school children requires interventions that are evidence based. Nutrition knowledge, attitudes
and practices (KAP) studies are thus ...
