Improvement of knowledge and postural habits after an educational intervention program in school students

To study the effect of an educational intervention programme concerning knowledge and postural habits for back health on a group of 10 to 11-year-old students. Two groups of 5th grade primary school students were selected. A control group (CG) (n=16), and an experimental group (EG) (n=16) who developed a back-health educational programme. A follow-up was carried out one month after the end of the intervention. The proposed educational intervention improved the results of both the knowledge and postural habits of the participants. The increase in the level of knowledge concerning health and back care in the daily lives of the EG ((x) over bar =6.32) was significantly greater than that observed in the CG ((x) over bar =3.86), with a high effect size (U = 29.500; Z = -3.717; p < 0.001, r = 0.66). In daily postural habits, the EG (<(x)over bar>=88.38) also increased their score significantly (U = 7.50; Z = -4.55; p < 0.001, r = 0.80) compared to the CG (<(x)over bar>=74.88). In both knowledge and postural habits, the scores increased in the intervention. The educational intervention programme studied improves both knowledge and postural habits for back health of the 5th grade students participating in the study. The Physical Education class seems to be an ideal environment to develop back health educational programmes.
