Increasing young children's vegetable consumption : effectiveness of a behavioural intervention in an early childhood development centre in Botswana

Abstract

Background: Although several studies have illustrated that the global population consumes a diet low in vegetables and fruits, there are still limited studies on health promoting strategies or interventions to help increase vegetable consumption in children at early childhood development (ECD) centres, especially in Southern Africa. It is important to address children’s eating behaviours early in childhood to increase dietary diversity, which will enable them to meet their nutritional requirements that support adequate growth and development as well as establish healthy eating behaviours into adulthood. Aim: The aim of this study was to determine the effect of a behavioural intervention on vegetable intake in children, aged 3 to 6 years, in an ECD centre in Gaborone, Botswana. Methods: A quasi-experimental study was conducted, employing the pre-test-post-test design. Firstly, data on habitual intake at home and at school was collected from parents and teachers respectively, using self-administered questionnaires. Children aged 3 to 6 years, from Dipeo Nursery School in Gaborone were provided with set portions of same-sized carrots and green beans on three respective days. On the second day, the social cognitive theory was applied through an intervention that consisted of posters of animated superhero cartoons promoting vegetable intake. The participants’ vegetable intake during the tests was assessed by counting the remaining number of vegetables on the plate and converted to the proportion consumed. Dependent t-tests were conducted to deduce inferences between pre-test, intervention, and post-test. Results: In total, 31 children were included in the study (17 boys, 14 girls). Parents reported carrots (65%), potatoes (61%) and tomatoes (55%) as the most frequent vegetables consumed in the preceding 24 hours. While the teachers reported cucumbers (91%), carrots (82%), corn (73%) and tomatoes (62%) as the most packed vegetables for school. Considering the intervention, there was no significant difference in the mean vegetable consumption (carrots and green beans) between the age groups on the pretest, intervention, or post-test days. For the total group, there was a significant increase in carrot consumption of 13.3% (t (30) = -3.99, p<0.001) from intervention (69.0, ±32.1%) to post-test (82.2, ±23.9%), as well as an increase of 7.1% from pre-test (75.1, ±28.3%) to post-test (82.2, ±23.9%), (t (30) = -2.09, p=0.045). Similarly, there was a 9% increase in green bean consumption (t (30) = -3.04, p=0.005) from intervention (53.1, ±36.6%) to post-test (62.1, ±35.0%). Conclusion: This study demonstrated that a behavioural intervention employing animated superhero cartoons paired with repeated exposure on three time points (pretest, intervention, and post-test) is effective in promoting vegetable intake in children aged 3 to 6 years in an ECD centre. It is recommended that children are encouraged to consume vegetables by means of visual characters and repeated exposure. Additionally, children should consume meals in an environment without distractions. The results of this study positively contribute to foundational data and demonstrate the need for further research on interventions on a larger scale.

Umongo: Nakuba ucwaningo olumbalwa luveze ukuthi emhlabeni jikelele mincane imifino nezithelo ekudleni okudliwa abantu, lusekhona ucwaningo oluncane lwezempilo olukhuthaza izindlela noma ukungenelela ukuze kusizwe izingane ziqinise ekudleni imifino ezikhungweni zokuqeqesha izingane ezincane (ama-ECD), ikakhulukazi eNingizimu ne-Afrika. Kubalulekile ukuthi ilungiswe zisencane izingane indlela ezidla ngayo ukuze zijwayelane nokudla okunhlobonhlobo, okuyozisiza zithole imisoco eziyidingayo ukuze zikhule futhi zithuthuke ngokwanele zize zibe abantu abadala abadla ngendlela enempilo. Inhloso: Inhloso yalolu cwaningo kwakuwukubona umthelela ongaba khona uma kungenelelwa endabeni yokuthi izingane, ezineminyaka emi-3 kuya kweyi-6, zidle imifino, esikhungweni se-ECD eGaborone, eBotswana. Izindlela Zokwenza: Kwenziwa ucwaningo olungokoqobo, olusebenzisa indlela yokuhlola ngokwesikhathi sangaphambi kwesivivinyo nesikhathi sangemva kwesivivinyo. Izingane, ezineminyaka emi-3 kuya kweyi-6, zaseNkulisa iDipeo eGaborone zanikwa ukudla okulinganayo kwezaqathe nobhontshisi ngezinsuku ezintathu ezihlukene. Ngosuku lwesibili, kwasetshenziswa indlela yokuthonya ingqondo yomuntu ngokwalokho akubona emphakathini ngoba kwakukhona izingqwembe ezazinopopayi abajabulile abangamaqhawe anamandla ababekhuthaza ukudliwa kwemifino. Kwaqoqwa kubazali nakothisha ngokufanayo imininingo eveza imikhuba yokudla emakhaya nasesikoleni, kusetshenziswa amaphephambuzo umuntu angazigcwalisela wona. Ukuthi umbambiqhaza udle imifino engakanani ngezikhathi zesivivinyo kwakuhlolwa ngokuthi kubalwe imifino esele epuletini bese kubonakala ukuthi udle engakanani. Kwenziwa izivivinyo zokuqhathanisa ukuze kufinyelelwe eziphethweni phakathi kwesikhathi sangaphambi kwesivivinyo, isikhathi sokungenelela kanye nesikhathi sangemva kwesivivinyo. Imiphumela: Sezizonke, izingane ezazikulolu cwaningo zazingama-31 (abafana abayi-17, amantombazane ayi-14). Abazali babika izaqathe (65%), amazambane (61%) kanye notamatisi (55%) njengemifino eyayivame ukudliwa kakhulu emahoreni 6 angama-24 adlulile. Ngokwalokhu kungenelela, wawungekho umehluko omkhulu ekudliweni kwemifino (izaqathe nobhontshisi) phakathi kwala maqembu ahlukaniswe ngokweminyaka yobudala ngezinsuku zangaphambi kwesivivinyo, zokungenelela noma zangemva kwesivivinyo. Kulo lonke leli qembu, kwenyuka kakhulu ukudliwa kwezaqathe kwaba ama-13.3% (t (30) = -3.99, p<0.001) kusukela ekungeneleleni (69.0, ±32.1%) kuya esikhathini sangemva kwesivivinyo (82.2, ±23.9%), kanye nokwenyuka kwama-7.1% okusuka esikhathini sangaphambi kwesivivinyo (75.1, ±28.3%) kuya esikhathini sangemva kwesivivinyo (82.2, ±23.9%), (t (30) = -2.09, p=0.045). Ngendlela efanayo, kwenyuka ngama-9% ukudliwa kukabhontshisi oluhlaza (t (30) = -3.04, p=0.005) kusukela esikhathini sokungenelela (53.1, ±36.6%) kuya esikhathini sangemva kwesivivinyo (62.1, ±35.0%). Isiphetho: Lolu cwaningo luveze ukuthi ukungenelela kusetshenziswa opopayi abajabulile abangamaqhawe anamandla nokuthi balokhu bevezwa ngokuphindelela kuyaphumelela ekukhuthazeni izingane ezineminyaka emi-3 kuya kweyi-6 ukuba zidle imifino esikhungweni se-ECD. Kunconywa ukuba izingane zikhuthazwe ukudla imifino kusetshenziswa izithombe zabalingiswa futhi ziboniswe zona ngokuphindelela. Ngaphezu kwalokho, izingane kufanele zidle ukudla zisendaweni engenaziphazamiso. Imiphumela yalolu cwaningo yenezela kahle emininingweni eyisisekelo futhi iveza ukuthi kunesidingo sokwenziwa kocwaningo olwengeziwe ngezinhlelo ezinkulu kakhulu zokungenelela.
