comparison group and focus group discussion
6 Comparative analysis of the Lahore study and the Vienna Study
8.2 Recommendations for future research
As the present study was the only study of its kind in the Pakistan context, there is need for further research to substantiate these findings. This is advised in order to ascertain whether similar findings will be found using other computer-based nutrition education programs. Due to the time and resource constraints, the study did not attempt to explore the effects of nutrition knowledge on change in dietary behavior. Future studies are highly recommended in order to explore this aspect.
The future studies to determine the effectiveness of computer-based nutrition education should include varied time spans for the intervention. Further research needs to be conducted, which addresses the effectiveness of computer-based nutrition education among other age groups (adolescent, elderly) and children in different settings (public schools). Follow-up after one or two year’s duration should be conducted to determine the effect of computer-based education on knowledge gain. Future studies need to explore the nexus between nutrition knowledge, attitudes and dietary behavior specifically in the Pakistani population. There is also need to explore the relationship between parental nutrition knowledge and children nutrition knowledge and dietary habits.
9 Summary
The purpose of the present study was twofold. It aimed to implement and evaluate a computer-based nutrition education intervention in the primary schools of Pakistan and to explore the acceptability of such a program in the Pakistani context. Secondly, the study attempted to compare results of the present study with the study results of ‘Cool Food Planet Kidz’ (Kreisel K, 2004). A total of 11 schools (344 children) including 4 intervention (147 children), 5 comparison (156 children) and 2 control (41 children) schools completed the study. Schoolchildren of 8-10 years of age participated in the study.
The study was carried out during the two-week practical experience of student teachers in Lahore, Pakistan. The comparison group received nutritional education through worksheets, board and card games. The intervention group used the computer-based tool (Cool Food Planet Kidz) along with worksheets, board and card games. The control group received no nutrition education. The nutrition knowledge was measured at baseline (t0), post-intervention (t1) and three-months’ follow-up (t2) with the help of the validated Nutrition Knowledge Questionnaire. In addition to the Nutrition Knowledge Questionnaire, focus group discussions, observation of the nutrition lessons and evaluation questionnaires were also employed to gather data.
The nutrition knowledge increased significantly from baseline to post-intervention in both post-intervention and comparison groups (p<0.001). No tangible difference was observed at post-intervention and follow-up between the two groups indicating that the computer-based tool did not support additional learning in children. The intervention effect was significantly maintained at three months’ follow-up, indicating the retention of nutrition knowledge gained. Younger children (8-9 years old) significantly (p=0.045)
retained more nutrition knowledge at three months follow-up as compared to the older children (10-11 years old) implying that nutrition intervention is more advantageous when started at an early age. Long-term knowledge gain and retention of knowledge is significantly higher among girls as compared to boys (Mann Whitney-U test p=0.025, p=0.024 respectively). Higher retention of nutrition knowledge in girls as compared to boys could be associated to the fact that girls found nutrition knowledge more relevant to their future prospective role as homemaker and caretakers.
Nutrition knowledge in all children was strongly associated with the indicators of socio-economic status i.e. occupational level of the father and the mother and Family Affluence Scale. No difference was detected in nutrition knowledge with regard to different levels of mother and father occupation and Family Affluence Scale between intervention and comparison groups. This suggests that computer-based tool did not prove beneficial concerning the socio-economic status.
Children and teachers both enjoyed learning and teaching nutrition concepts through computers. Nevertheless, Student teachers highlighted many important factors that need to be taken into account in order to integrate computer-assisted education in Pakistani primary schools successfully.
The comparison with the Vienna study revealed that at baseline, nutrition knowledge (mean number of correct answers) of Vienna children was higher as compared to the Lahore children, indicating that nutrition knowledge of Pakistani children is very low as compared to the children in Vienna study. It signifies the inadequacy of Pakistani school curricula in particular and society in general in providing knowledge related to nutrition and healthy eating to children. At three months’ follow-up children in the Vienna study notably retained more nutrition knowledge as compared to the Lahore children
suggesting that children in Vienna have more opportunities to get nutrition-related information from their environment.
The study results have provided a strong foundation for incorporating nutrition education intervention in primary schools. Computer-based tools were found helpful in disseminating nutrition education. However, they were not the panacea. Other creative mediums were almost equally effective in disseminating nutrition knowledge. The low level of nutrition knowledge urgently demands incorporation of nutrition education in the school curriculum.
10 Zusammenfassung
Das Ziel der Studie war einerseits die Einführung und Evaluierung einer computergestützten Interventionsmaßnahme im Bereich der Ernährungsbildung in pakistanischen Grundschulen und andererseits die Prüfung der Akzeptanz eines Programms dieser Art. Weiters wurden die Ergebnisse der vorliegenden Studie mit den Resultaten des Projektes „Cool Food Planet Kidz“ (Kreisel K, 2003) verglichen. An der Studie nahmen insgesamt 11 Schulen (344 Kinder) teil, wobei 4 Schulen als Interventionsgruppe (147 Kinder), 5 Schulen als Vergleichsgruppe (156 Kinder) sowie 2 Schulen als Kontrollgruppe (41 Kinder) dienten. Das Alter der teilnehmenden Kinder lag zwischen 8 und 10 Jahren.
Die Studie wurde während einer zweiwöchigen Praxis von Lehramtsstudenten in Lahore, Pakistan durchgeführt. Der Vergleichsgruppe wurde Ernährungsbildung mittels Arbeitsblättern sowie Brett- und Kartenspielen vermittelt. Die Interventionsgruppe verwendete begleitend zu den Arbeitsblättern, Brett- und Kartenspielen das computergestützte Programm. Die Kontrollgruppe erhielt keine Ernährungsbildung. Das Ernährungswissen wurde zu Beginn (t0), nach der Intervention (t1) und nach drei Monaten (t2) anhand eines validierten Fragebogens zum Ernährungswissen getestet. Zusätzlich zum Fragebogen wurden Gruppendiskussionen, Beobachtungen der Ernährungserziehung sowie ein Evaluierungsfragebogen eingesetzt, um Daten zu erfassen.
Sowohl in der Interventions- als auch in der Vergleichsgruppe stieg das Ernährungswissen nach Intervention signifikant an (p<0,001). Allerdings konnten zwischen den beiden Gruppen keine relevanten Unterschiede sowohl nach Intervention als auch beim Follow-Up festgestellt werden. Das computergestützte Programm führte somit zu keinem zusätzlichen Lerneffekt bei den Schülern. Beim Follow-Up wurden der Interventionseffekt und somit
das erworbenen Ernährungswissen signifikant aufrechterhalten. Jüngere Kinder (8-9 Jahre) konnten beim Follow-Up nach drei Monaten signifikant mehr (p=0,045) vom erworbenen Ernährungswissen wiedergeben als ältere Kinder (10-11 Jahre), was bedeutet, dass Ernährungsbildung von größerem Nutzen ist, wenn sie in einem jüngeren Alter begonnen wird. Eine längerfristige Steigerung und Beibehaltung des Wissens waren bei Mädchen signifikant höher als bei Buben (Mann-Whitney-U-Test p=0,025, bzw.
p=0,024). Die bessere Beibehaltung des Wissens bei Mädchen könnte mit der Tatsache in Zusammenhang stehen, dass Mädchen Ernährungswissen für ihre angehende Rolle als Hausfrauen und Mütter für relevanter erachteten.
Bei allen Kindern war Ernährungswissen stark mit dem sozioökonomischen Status (z.B. Beruf von Vater und Mutter, Wohlstand der Familie) assoziiert.
Zwischen Interventions- und Vergleichsgruppe konnten keine Unterschiede im Ernährungswissen in Bezug auf Beruf der Eltern sowie Familienwohlstand gefunden werden. Somit zeigte der sozioökonomische Status keine Auswirkungen auf die Vorteile der Anwendung des computergestützten Programms.
Die Anwendung des Computers in der Ernährungsbildung wurde von den Kindern, wie auch von den Lehrern gut angenommen. Nichtsdestotrotz zeigten die Lehramtsstudenten viele relevante Punkte auf, die in Erwägungen gezogen werden müssen, um computerunterstützten Unterricht erfolgreich in den pakistanischen Grundschulen integrieren zu können.
Der Vergleich der Baselineergebnisse mit den Resultaten der „Cool Food Planet Kidz“-Studie zeigte, dass das Ernährungswissen (durchschnittlich Anzahl an korrekten Antworten) bei den Kindern aus Wien wesentlich besser war als bei den Kindern aus Lahore. Dies hebt die Unzulänglichkeit in der pakistanischen Gesellschaft im Allgemeinen und insbesondere die Unzulänglichkeit der Bildungsinhalte an pakistanischen Schulen hervor,
Kindern Wissen über gesunde Ernährung zu vermitteln. Beim Follow-Up nach drei Monaten zeigte sich, dass die Kinder der Wiener Studie deutlich mehr Ernährungswissen behalten konnten als die Kinder aus Lahore, was darauf zurückführen sein könnte, dass Kinder in Wien mehr Möglichkeiten haben, in ihrem Umfeld zu ernährungsbezogenen Informationsquellen zu gelangen.
Die Ergebnisse dieser Studie bilden ein solides Fundament für die Einführung von Interventionsmaßnahmen im Bereich Ernährungsbildung in Grundschulen. Computerunterstützte Programme wurden als hilfreich angesehen, um Ernährungsbildung zu verbreiten. Jedoch sind diese kein Wundermittel. Andere kreative Medien waren beinahe ebenso effektiv in der Verbreitung von Ernährungswissen. Das niedrige Niveau des Ernährungswissens erhebt dringenden Anspruch auf die Berücksichtigung von Ernährungsbildung in den Lehrplänen.
