Full textENGLISH ABSTRACT: Introduction and Objectives: Schools can serve as a supportive environment for the promotion of healthy eating in order to prevent childhood overweight and obesity and the development of noncommunicable diseases such as cardiovascular diseases, type 2 diabetes mellitus, fatty liver disease, muscoskeletal disorders and some cancers. Tuck shops at schools often offer unhealthy items that are energy dense and high in fat and/or sugar with a low content of vitamins, minerals and dietary fibre. The availability of unhealthy items in tuck shops prevents learners from making healthy food choices, since children tend to choose unhealthy foods when given a choice. In addition to unhealthy items offered by tuck shops, learners also bring unhealthy items to school in their lunchboxes. The aim of the study was to investigate the influence of a nutritionally-regulated tuck shop on primary school learners’ perceptions, attitudes and behaviour towards healthy eating in a Bloemfontein, Afrikaans medium, co-education primary school, and compare it to learners of a school with a conventional tuck shop. Methods: In a cross-sectional survey with an analytical component, grade 2 to 7 learners in a school with a nutritionally-regulated tuck shop (n=116) and a school with a conventional tuck shop (n=141) completed a questionnaire. Six learners per grade also took part in focus group discussions. Questions related to lunchbox contents and perceptions, attitudes and behaviour towards the tuck shop and healthy eating. Nutritional information of the items available for purchase at each of the school tuck shops was collected. Results: The lunchboxes of learners in the school with a nutritionally-regulated tuck shop contained significantly (p<0.05) more healthy items (fruit, water and muffins), as well as significantly more unhealthy items (sweets and chips). The items offered by the nutritionally-regulated tuck shop contained approximately half the kilojoules compared to items offered by the conventional tuck shop. Learners in the school with a nutritionally-regulated tuck shop liked certain fruits and vegetables significantly (p<0.05) more than learners in the school with a conventional tuck shop. Statistical significant differences (p<0.05) between different grades and gender showed that grade 2 learners in both schools had a less positive attitude towards certain fruit and vegetables compared to the older learners, while girls in both schools were more positive towards certain fruits and vegetables compared to boys. Younger learners had a more positive attitude towards their nutritionally-regulated tuck shop than older learners. In both schools learners had similar perceptions regarding the particular school’s tuck shop and healthy eating. Conclusion: The hypothesis that learners in a school with a nutritionally-regulated tuck shop have positive attitudes, perceptions and behaviour towards healthy eating was rejected. The availability of healthier items in a school tuck shop had a positive influence on certain behaviours and attitudes of learners, but the potential value of controlling the type of items available for purchase at schools might be counteracted by lunchbox contents, certain fixed eating patterns, perceptions of learners and previous exposure to a conventional tuck shop. Recommendations include a multi-pronged approach such as the Health Promoting Schools concept.
AFRIKAANSE OPSOMMING: Inleiding en doelwitte: Skole bied ‘n omgewing waar goeie eetgewoontes bevorder kan word ten einde oorgewig en vetsug in kinders te voorkom, asook die ontwikkeling van nie-oordraagbare siektes soos kardiovaskulêre siektes, tipe-2 diabetes mellitus, lewervervetting sindroom, ortopediese komplikasies en sekere soorte kanker. Snoepies in skole voorsien meestal ongesonde items met ‘n hoë energie, vet- en/of suikerinhoud en wat laag is in vitamiene, minerale en dieetvesel. Die beskikbaarheid van ongesonde items in snoepies verhoed dat leerders gesonde voelselkeuses uitoefen, omdat kinders geneig is om voorkeur aan ongesonde kos te gee as hulle 'n keuse gebied word. Benewens die ongesonde items wat snoepies aanbied, neem leerders boonop ongesonde kos in hul kosblikke skooltoe. Die doel van die studie was om by 'n Afrikaans dubbelmedium laerskool in Bloemfontein die invloed van ‘n voedingkundig-gereguleerde snoepie op leerders se persepsies, houdings en gedrag teenoor gesonde eetgewoontes te ondersoek en te vergelyk met leerders in 'n skool met 'n konvensionele snoepie. Metodes: In ‘n deursnit-opname met ‘n analitiese komponent, het graad 2 tot 7 leerders in ‘n skool met ‘n voedingkundig-gereguleerde snoepie (n=116) en ‘n skool met ‘n konvensionele snoepie (n=141), ‘n vraelys ingevul. Ses leerders in elke graad in elk van die skole het ook aan fokusgroepbesprekings deelgeneem. Vrae het oor die inhoud van kosblikke, asook persepsies, houding en gedrag teenoor die snoepie en gesonde eetgewoontes, gehandel. Voedingsinligting rakende die items wat in elk van die skole se snoepies verkoop word, is ook ingesamel. Resultate: Die kosblikke van leerders in ‘n skool met ‘n voedingkundig-gereguleerde snoepie het statisties beduidend (p<0.05) meer gesonde items bevat (vrugte, water en muffins), maar ook beduidend meer ongesonde items (lekkergoed en aartappelskyfies). Voedsel-items wat in die voedingkundig-gereguleerde snoepie beskikbaar was, het omtrent die helfte minder energie bevat as voedsel-items wat in die konvensionele snoepie beskikbaar was. Leerders in ‘n skool met ‘n voedingkundig-gereguleerde snoepie het beduidend (p<0.05) meer van sekere groente en vrugte gehou as leerders in ‘n skool met ‘n konvensionele snoepie. Statisties beduidende (p<0.05) verskille tussen verskillende grade en die houding van verskillende geslagte dui daarop dat graad 2 leerders in albei skole minder positief gevoel het oor sekere groente en vrugte as ouer leerders, terwyl meisies in albei skole ‘n meer positiewe houding teenoor sekere groente en vrugte getoon het as seuns. Jonger leerders het ‘n meer positiewe houding teenoor hulle voedingkundig-gereguleerde snoepie getoon as ouer leerders. In albei skole het leerders soortgelyke persepsies rondom hul onderskeie skole se snoepies en gesonde eetgewoontes openbaar. Gevolgtrekking: Die hipotese dat leerders in ‘n skool met ‘n voedingkundig-gereguleerde snoepie positiewe persepsies, houding en gedrag teenoor gesonde eetgewoontes toon is nie aanvaar nie. Die beskikbaarheid van gesonder items in ‘n skoolsnoepie het 'n positiewe invloed op sekere eetgewoontes en houdings van die leerders, maar die potensiële waarde daarvan om die tipes voedsel wat by skole te koop aangebied word te reguleer mag egter teengewerk word deur kosblikke se inhoud asook sekere vaste eetpatrone, persepsies van leerders en vorige blootstelling aan ‘n konvensionele snoepie. ‘n Veelvoudige benadering soos die konsep van ‘n Gesondheidbevorderingskool word aanbeveel.

Full textBakgrund En välbalanserad näringsrik kost är viktig för den gravida kvinnan och det växande fostret, så även för deras framtida hälsa. En bristfällig kost kan utgöras av både överförbrukning av energirika livsmedel vilket kan leda till högre viktuppgång än vad som är hälsosamt och bristande intag av viktiga näringsämnen. Kostintag regleras av komplexa biologiska system där flera faktorer är inblandade däribland steroidhormonet allopregnanolon. Det övergripande syftet med denna avhandling är att under och efter graviditet beskriva kostintag, vitamin D-nivåer, kostinformation och kostförändringar och att studera allopregnanolons relation till viktökning. Metod Studie I var en kvalitativ studie med fokusgruppsintervjuer med 23 gravida kvinnor. Texten analyserades med innehållsanalys. Studie II var en kvantitativ tvärsnittsstudie som genomfördes i tidig graviditet (n = 209) och med en grupp icke-gravida kvinnor (kontrollgrupp) (n=206). Självrapporterade kostdata från ett frågeformulär analyserades med beskrivande, jämförande statistik och en klusteranalysmodell (Partial Least Squares modellering). Studie III hade en kvantitativ longitudinell design. Vitamin D-koncentrationer analyserades hos 184 kvinnor, vid fem tillfällen under graviditeten och efter förlossningen. Beskrivande, jämförande statistik och en linjär mixad regressionsmodell användes. Studie IV var en kvantitativ longitudinell studie med 60 kvinnor. Koncentrationerna av allopregnanolon analyserades vid graviditetsvecka 12 och 35. Beskrivande och jämförande statistik samt Spearman’s korrelation användes för att beskriva samband mellan viktökning och koncentrationer av allopregnanolon. Resultat Intervjuerna i studie I visade att kvinnor ville veta mer om olika typer av mat för att minska en eventuell risk för sina barn men kostinformation var delvis upp till dem själva att ta reda på. De VIII uttryckte känslor av osäkerhet och skuld om de råkat äta något ”förbjudet”. Rekommendationerna följdes så väl som möjligt, tillsammans med sunt förnuft för att hantera kostförändringar. Huvudteman var ”Söka information på egen hand”, ”Få professionell rådgivning när problem uppstår”, ”Känna sig osäker” och ”Ta ansvar med en nypa salt”. I studie II kunde man se vissa skillnader i kostmönster bland de gravida kvinnorna jämfört med kontrollgruppen: mindre intag av grönsaker (47 g/dag), potatis/ris/pasta (31 g/dag), kött/fisk (24 g/dag) och alkohol och tobak/snus och ett högre intag av kosttillskott. Både gravida kvinnor och kontrollgruppen hade lägre intag av folsyra via kosten med 45 % (gravida) och 22 % (kontrollgruppen) än de gällande rekommendationer som är (500 resp 400 g/dag). I studie III såg man att inta et av vitamin D var 34 % lägre än rekommendationen på 10 µg/dag. Minst en tredjedel av deltagarna hade otillräckliga plasma nivåer av vitamin D, under 50 nmol/L. Årstid var en stark faktor som påverkar det longitudinella mönstret. Graviditetsvecka, säsong, totala energiintaget, intaget av vitamin D och multivitamintillskott under de senaste 14 dagarna var faktorer som relaterade till Dvitaminnivåer. I studie IV sågs ett samband mellan allopregnanolon-koncentrationer vid graviditetsvecka 35 och viktökning från vecka 12 till 35 (p = 0,016). Det sågs också ett samband mellan ökningen av allopregnanolon (vecka 12–35) och viktökningen (se ovan) (p = 0,028). Slutsatser Kostrekommendationer beskrevs som motsägelsefulla och förvirrande och kostråden de fick uppfattades som otillräckliga. Kvinnorna tog itu med sina kostförändringar och sökte information på egen hand men hade önskat mer omfattande råd från barnmorskan. Intaget av vitaminer viktiga för graviditeten var lägre än rekommendationerna, vilket också bekräftas av låga plasmanivåer av D-vitamin hos cirka en tredjedel av de gravida kvinnorna. D-vitaminnivåerna nådde en topp i slutet av graviditeten. Graviditetsvecka och säsong på året påverkade D vitaminnivåer, så även intag via mat och kosttillskott. Orsakertill viktökning är komplexa och beror på många faktorer. Allopregnanolon är en faktor som sågs relatera till viktökningen hos de undersökta gravida kvinnorna.

Full textL'étude en question a évalué les facteurs comportementaux associés à la prise de poids chez les jeunes adolescentes. Les comportements incluent tous les aspects sociaux liés à l'alimentation tels que sauter le petit déjeuner, manger par besoin affectif, se goinfrer et se priver volontairement. Avec l'augmentation importante de l'obésité parmi les jeunes, une étude plus approfondie devra se concentrer sur les aspects psychologiques liés à l'alimentation afin d'obtenir des interventions adéquates pour apprendre aux jeunes à bien s'alimenter. On a trouvé que le fait de se goinfrer et le fait de manger avec la famille était associé de façon importante à l'adiposité chez les adolescentes et à l'intolérance de glucose de la mère durant la grossesse. L'idée de cette thèse est révolutionnaire car elle suggère que les facteurs comportementaux contribuent aux effets de la grossesse affecté par l'intolérance de glucose. Cette thèse nous donne une perspective plus large afin d'atteindre des stratégies d'interventions plus effectives auprès des femmes à haut risque ainsi que de leur progéniture.

Full textwith a child who has CF. The 'objective assessment of knowledge indicated a significant m improvement in' children's knowledge in the short-term. There were no statistically significant improvements in any of the other parameters assessed. The lack of significant improvements in self-management, behaviour, dietary intake and anthropometry may have been because the program had no effect, the parameters assessed or the instruments used (particularly the questionnaires) were not sufficiently sensitive, the sample size (which was determined by the CF population available) was too small or the duration of the intervention and follow-up was too short.Conclusion: Carers' unanimous recommendation of Go and Grow with CF, together with high levels of perceived learning, reported increase in confidence and improvement in children's knowledge in the short-term, indicate the benefits of the program.Although there was no statistically significant improvement in the anthropometric measurements after the intervention, 'the extensive data obtained during this study suggest that measurements of height and weight may underestimate the presence of poor nutritional status. It is likely that comprehensive assessments of body composition of children with CF would be useful in detecting mild degrees of malnutrition and in providing information about the effects of nutritional status on morbidity and mortality associated with the disease.Fat-based pancreatic enzyme replacement therapy dosing warrants further investigation given that parents had a strong preference for this method and that fat absorption remains abnormal in the majority of individuals who have pancreatic insufficiency. Evaluation of all pancreatic enzyme replacement therapy dosing methods are needed and this research suggests that dose should be assessed on a meal and snack basis, rather than just on daily intake, in order ++
for levels of adherence to be examined.The apparent absence of a long-term effect of a single exposure to the program on knowledge suggests that regular, ongoing education and counselling is required by families to reinforce aspects related to the child's current stage of development and disease status.

Full textLes modèles de repas et de comportement alimentaire chez les animaux et les humains sont appris au fil du temps et impliquent des facteurs environnementaux et biologiques/innés. On a montré que les animaux peuvent apprendre à anticiper certains résultats suite à un comportement (conditionnement instrumental), telle la faim/satiété anticipée. Signalé pour la première fois en 1957 par Jacques le Magnen, des rats apprennent à manger une petite quantité de nourriture suivie d'une courte période de privation de nourriture plutôt que d'un aliment suivi d'un long jeûne. Un régime riche en gras (RRG) et l'obésité influent directement l'hippocampe et donc l'apprentissage et les processus de mémoire. Les mécanismes sont insaisissables, mais les principaux mécanismes proposés comprennent l'insulino-résistance, l'intolérance au glucose et la plasticité neuronale réduite. D'autres facteurs essentiels dans le lien entre le RRG et l'apprentissage sont les hormones telles que la ghréline et la leptine, qui jouent un rôle dans l'ingestion alimentaire et l'homéostasie énergétique et aussi dans les mécanismes d'apprentissage et la mémoire compte tenu de leur capacité à traverser la barrière hémato-encéphalique. L'ingestion anticipatoire est un comportement instrumental renforcé par la faim qui est atténué par l'ingestion d'un régime de maintien RRG.. Le but de ce travail était d'analyser les résultats d'une expérience sur les effets d'un régime alimentaire de maintien RRG sur la prise alimentaire, l'apprentissage de l'ingestion alimentaire anticipatoire et le poids et la composition corporelle de rats mâles adultes. Trente rats Sprague Dawley ont été assignés au hasard à un régime de maintien RRG ou au Purina chow et ont été soumis à un modèle expérimental de l'apprentissage anticipée pendant 10 cycles de 2 jours, y compris une période de privation de nourriture (8 h). Les rats nourris avec le RRG on été groupés selon leur gain de poids et de gras corporel. Chez les animaux qui ont gagné beaucoup ou peu de poids corporel, le gras corporal total ainsi que le gras abdominal avant et après l'entraînement de l'apprentissage anticipé n'étaient pas différents; cependant le gain de gras corporel total et le gras abdominal étaient significativement plus élevés que chez les animaux témoins. Comme le gain de poids n'était pas corrélé avec le gain de gras corporel, les animaux nourris avec le RRG ont été subdivisés en quatre sous-catégories comprenant ceux qui : avaient gagné beaucoup de poids mais peu de gras corporel, avaient gagné beaucoup de poids et de gras corporel, ainsi que les rats qui avaient gagné peu de poids mais beaucoup de gras corporel et ceux qui avaient gagné peu de poids et peu de gras corporel. L'apprentissage de l'ingestion anticipatoire a été observé chez tous les animaux, mais la proportion des premiers pics d'ingestion au cours des premiers cycles d'entraînement était plus élevée chez les rats nourris avec le RRG, indiquant un apprentissage plus rapide. Cependant, chez les animaux nourris avec le RRG, ceux qui avaient gagné le plus de gras corporel (g) avaient un apprentissage plus lent. Les effets significatifs du régime alimentaire et du cycle indiquaient une évidence de récompense, avec un effet plus robuste chez les animaux qui avaient gagné le moins de poids et de gras corporel. Cela indique qu'un type spécifique de composition corporelle développé par RRG peut influencer certains processus d'apprentissage. L'idée que les processus cognitifs contribuent au contrôle de la prise alimentaire chez le rat est aussi importante chez l'homme. L'ingestion alimentaire anticipatoire reflète une capacité de gestion de la faim : autrement dit, les humains peuvent apprendre inconsciemment à manger plus de nourriture avant une période de faim, précédant l'heure conventionnelle à manger. Une déficience de cette capacité pourrait contribuer au développement de l'obésité, relevant de mécanismes mentaux organisant le comportement alimentaire.

Full textLa tesis pretende analizar la relación entre los hábitos de actividad física/ejercicio físico, sedentarismo y alimentación en niños con sobrepeso/obesidad. En este sentido, se han redactado 5 artículos donde se han estudiado los hábitos activos, las conductas sedentarias y de alimentación, la respuesta al ejercicio físico agudo al andar a diferentes pendientes a nivel energético. Se ha llevado a cabo una primera evaluación del Programa Nereu y finalmente se ha propuesto la evaluación de la efectividad del Programa Nereu, como herramienta integral vinculada a la salud pública en el ámbito de la atención pediátrica para el tratamiento del sobrepeso y la obesidad infantil. En el artículo 1.1 y 1.2, se observó que practicar al menos 3 horas/semana de ejercicio físico se asoció con menor prevalencia de sobrepeso y mejor condición física. En el artículo 2, a mismas intensidades de trabajo a nivel energético y ventilación los valores eran superiores en los grupos de niños/as con obesidad en relación a los de sobrepeso. En el artículo 3, los niños aumentaron el tiempo dedicado a actividades de moderada y alta intensidad y se redujo el IMC z-score y las conductas sedentarias. Finalmente, se ha propuesto un protocolo de estudio como propuesta de futuro.
The porpoise of the thesis was to analyze the relation between physical activity/exercise habits, sedentary behavior and foot intake in overweight/obesity children. In this sense, 5 articles have been written. Where, active habits, sedentary behavior or foot intake, the response to acute physical exercise in overweight and obese children when walking at different gradients at an energy expenditure level, an initial assessment of the Nereu Programme have been studied. Finally, a proposal has been put forward on the Nereu Programme as an integral tool linked to public health in the field of pediatric care in the treatment of childhood overweight and obesity. Article 1.1 and 1.2, practice at least 3 hours/week of physical activity was associated with lower prevalence of overweight and better physical condition. In Article 2, same intensities of work on an energetic and ventilation values were higher in the groups of obese children compared to overweight children. Article 3, children increased the time they spent in moderate and high intensity activities and in contrast, BMI z-scores and sedentary behaviors were reduced. Finally, a study protocol has been put forward as a proposal for the future.

Studies have found that signs of distorted body image perception and body dissatisfaction can be detected in children as young as 8 or 9 years old. Aim: The current study served to assess the extent of this problem in Northeastern Johannesburg, South Africa, in order to allow for the necessary intervention steps (e.g. development of school-based programmes) to deal with this problem to be put in place. Method: The study was a cross-sectional analytical study with a descriptive component. Two hundred and four girls (81.37% Black, 15.20% White and 3.43% Coloured or Indian) aged between 96 and 119 months in primary schools in Northeastern Johannesburg were selected for this study using systematic random sampling. They were required to complete a questionnaire about their body image perception and weight control behaviours, as well as undergo anthropometric measurements (i.e. weight and height). Results: This study found that the subjects placed much importance on being thin, with subjects stating that they thought if a girl was thin she would be more popular (63.96%), have better self esteem (69.63%), be more attractive (69.11%), be more feminine (73.80%) and be healthier (66.84%). When asked to identify the girl from a silhouette drawing that most resembled themselves, 45.00% of the subjects were able to accurately identify which girl’s size most resembled their own, whereas 48.50% saw themselves as thinner than they are and 6.50% saw themselves as fatter than they are. In addition, the majority of subjects (69.61%) said that they were very happy with their weight and the majority (74.88%) classified it as “just right.” However, despite these findings, there was still significant body dissatisfaction evident in the group with 50.25% of the subjects wanting to be thinner, 28.57% wanting to be fatter and only 21.18% not wanting to be thinner or fatter than they currently are. Of the subjects participating in the study, 50.98% had tried to lose weight in the past and 28.71% had tried to gain weight. Also, various factors (i.e. media, cultural, family and peer influences), were shown to have a significant influence on the subjects’ body image perception. Other factors such as socioeconomic status and physical activity level had no significant link with the subjects’ body image perception. Conclusion: There is a significant problem with poor body image perception and resultant weight control behaviours in this age group. Clearly, there is a need for body image improvement programmes to be put in place in primary schools so as to prevent preadolescent girls from moving towards a lifetime of suffering with body dissatisfaction or, even worse, developing a life-threatening eating disorder.
AFRIKAANSE OPSOMMING: Agtergrond: ’n Swak liggaamsbeeld en liggaamsontevredenheid is bekende risikofaktore vir die ontwikkeling van eetsteurnisse. Volgens studies kan tekens van ’n verwronge liggaamsbeeld en liggaamsontevredenheid reeds by jong kinders, van 8 of 9 jaar, bespeur word. Doel: Hierdie studie het gepoog om die omvang van dié probleem in die noordooste van Johannesburg, Suid-Afrika, te bepaal ten einde die nodige intervensiemaatreëls te tref (byvoorbeeld om skoolgebaseerde programme te ontwikkel) om die probleem die hoof te bied. Metode: Die studie is ’n dwarssnit analitiese studie met ’n beskrywende komponent. Met behulp van sistematiese, ewekansige steekproefneming is 204 laerskoolmeisies (81.37% Swart, 15.20% Wit en 3.43% Bruin of Indiër) van tussen 96 en 119 maande uit die noordooste van Johannesburg as proefpersone vir die studie gekies. Die meisies moes elk ’n vraelys oor hul liggaamsbeeld en gewigsbeheergedrag invul sowel as antropometriese meting van gewig en lengte ondergaan. Resultate: Die studie het gevind dat die proefpersone baie waarde daaraan heg om maer te wees. Hulle reken onder meer dat, indien ’n meisie maer is, sy waarskynlik gewilder sal wees (63.96%), ’n beter selfbeeld sal hê (69.63%), aantrekliker sal wees (69.11%), vrouliker (73.80%) en gesonder sal wees (66.84%). Toe hulle op ’n profielskets ’n meisie moes uitwys na wie hulle dink hulle die meeste lyk, kon 45.00% van die proefpersone akkuraat uitwys watter meisie se grootte die meeste met hulle s’n ooreenstem, terwyl 48.50% hulself as maerder en 6.50% hulself as vetter beskou het as wat hulle werklik is. Die meerderheid van die proefpersone (69.61%) was oënskynlik gelukkig met hul gewig en die meeste (74.88%) het hul gewig as “net reg” beskryf. Tog, ondanks dié bevindinge, was daar steeds beduidende liggaamsontevredenheid by die groep: 50.25% van die subjekte wil maerder wees, 28.57% vetter en slegs 21.18% nie maerder óf vetter as wat hulle tans is nie. Van die studiedeelnemers het 50.98% al voorheen probeer gewig verloor, terwyl 28.71% al probeer gewig aansit het. Verskeie faktore (soos media-, kulturele, gesins- en portuurinvloede) blyk ook ’n beduidende impak op die proefpersone se liggaamsbeeld te hê. Daarenteen toon ander faktore, soos sosio-ekonomiese status en vlak van fisieke aktiwiteit, geen wesenlike verband met die proefpersone se liggaamsbeeld nie. Gevolgtrekking: Hierdie ouderdomsgroep blyk ’n beduidende probleem met ’n gebrekkige liggaamsbeeld en gevolglike gewigsbeheergedrag te hê. Daar is duidelik ’n behoefte aan programme om laerskoolmeisies se liggaamsbeeld te verbeter ten einde te voorkom dat preadolessente meisies weens liggaamsontevredenheid ’n leeftyd van swaarkry tegemoetgaan of, selfs erger, ’n lewensgevaarlike eetsteurnis ontwikkel.

Full textResearch suggests that parents&rsquo
feeding practices play a critical role in the development of children&rsquo
s tastes, eating habits, nutrition and eventual weight status. Thus if parental feeding practices play such a critical role, the question arises as to whether there is a difference in parental feeding practices that determine different developments in children&rsquo
s nutritional habits. Furthermore, feeding practices are possibly based on the nutritional knowledge of parents. The aim of this study was to assess the Body Mass Index (BMI), nutritional knowledge and behaviour of primary care-givers. This study followed the quantitative research paradigm. A sample of 147 staff members, who were primary care- givers of children at a University in the Western Cape was self-selected to participate in the study. Only primary care-givers of children were invited to participate. The primary care-givers were asked to complete two online questionnaires, the Comprehensive Child Feeding Questionnaire (CFPQ) developed by Musher-E-Eisenman and Holub (2007), and the General Nutritional Knowledge Questionnaire (GNKQ) for adults. Data analysis was done by means of the Statistical Package for Social Sciences (SPSS17). Results indicated that the majority of participants were overweight (46% of the participants). Primary care-givers across all body mass index groups did not lack nutritional knowledge but variations in behaviour were found with regard to feeding practices. However similarities were found in the BMI categories in the areas of teaching about nutrition, pressure to eat at meal times
and encouraging balance and variety.

Full textENGLISH ABSTRACT: Background: Eating disorders are an important cause of morbidity and mortality in adolescent and young adult women. There is some evidence that Eating disorders may be more common in Jewish females than in their non-Jewish counterparts. Individuals with abnormal attitudes as defined by the Eating Attitudes Test (26-Item version) (EAT-26) are at increased risk of developing an eating disorder. School teachers are required to take an active role in the currently favoured ecological approach to the prevention of eating disorders. Objectives: The current study sought to determine the prevalence of abnormal eating attitudes and weight loss behaviours in a Jewish female adolescent sample and to investigate school teachers’ awareness of these factors and their attitudes towards a school programme to address these. Methods: A cross-sectional study of girls in grades 8 to 11 and teachers of both genders was undertaken at a “traditional” Jewish high school in Johannesburg, South Africa. A questionnaire consisting of the EAT-26 and a modified section of the United States Youth Risk Behaviour Survey (YRBS) was completed by pupils. A questionnaire developed by the researcher for the study was completed by teachers. Results: Two hundred and twenty pupils (response rate 84.3%) and 38 teachers (52.1%) participated. Twenty percent of pupils (n=43) had EAT-26 scores greater than or equal to 20 and 30.2% were found to require clinical evaluation for a potential eating disorder Thirty two point seven percent (n=72) of girls considered themselves to be overweight. Sixty four percent (n=139) were trying to lose weight at the time of the study and 19.1% (n=42) had engaged in one or more extreme methods of weight loss (fasting, purging or non-prescribed medication) in the past 12 months. Most teachers (81.6%, n=29) underestimated the proportion of girls requiring clinical evaluation and 71.1% (n=27) underestimated the extent of current weight loss attempts. Almost all (97.3%, n=37) the teachers recognised the need to address disordered eating attitudes and patterns in the school but only 34.2% (n=13) viewed the school as the appropriate place, would be prepared to participate and would give up class time. Conclusions: This is the first study to document the presence of abnormal eating attitudes among Jewish adolescent females in South Africa. The prevalence fell within the upper end of the range of rates reported in studies of adolescent girls in South Africa and abroad. Dieting and attempts at weight loss are common in this population and are also in keeping with the findings from international studies. This is the first study to measure teachers’ awareness of the eating attitudes and weight loss behaviours of girls attending the school at which they teach. The teachers participating in this study were not fully aware of the extent to which eating-related issues affect female pupils. Over and above this, there appears to be a resistance to facilitating and participating in a school programme addressing these issues. A qualitative exploration of this could yield valuable insights.
AFRIKAANSE OPSOMMING: Agtergrond: Eetstoornisse is 'n belangrike oorsaak van morbiditeit en mortaliteit in adolessente en jong volwasse vroue. Daar is bewyse dat Eetstoornisse meer algemeen mag voorkom in Joodse vroue vergeleke met hul nie-Joodse eweknieë. Individue met 'n abnormale houding soos gedefinieer deur die Eet-Houding-Toets (“Eating Attitudes Test”) (26-punt weergawe) (EAT-26) het 'n verhoogde risiko om 'n eetstoornis te ontwikkel. Daar word van onderwysers verwag om 'n aktiewe rol te speel in die ekologiese benadering om eetstoornisse te voorkom, wat tans voorkeur geniet. Doelstellings: Die huidige studie het gepoog om die voorkoms van abnormale houding en gedrag ten opsigte van eet en gewigsverlies in 'n steekproef van Joodse vroulike adolessente te bepaal, asook om ondersoek in te stel of onderwysers bewus is van hierdie faktore en hul houding teenoor 'n skoolprogram wat dit aanspreek. Metodes: 'n Dwarssnit studie van meisies in graad 8 tot 11 en onderwysers van beide geslagte was uitgevoer by 'n "tradisionele" Joodse hoërskool in Johannesburg, Suid-Afrika. 'n Vraelys bestaande uit die EAT-26 en 'n aangepasde afdeling van die “United States Youth Risk Behaviour Survey (YRBS)” is voltooi deur studente. Onderwysers het 'n vraelys voltooi wat vir die studie ontwikkel is deur die navorser. Resultate: Tweehonderd-en-twintig leerlinge (responskoers 84.3%) en 38 onderwysers (52.1%) het deelgeneem. Twintig persent van leerlinge (n=43) het EAT-26 tellings groter as of gelyk aan 20 gehad en daar was bevind dat 30.2% kliniese evaluering vir 'n potensiële eetstoornis benodig. Twee-en-dertig punt sewe persent (n=72) van meisies het hulself as oorgewig beskou. Vier-ensestig persent (n=139) het probeer om gewig te verloor ten tye van die studie en 19.1% (n=42) het betrokke geraak by een of meer ekstreme metodes van gewigsverlies (vas, purgasie of nievoorskrif medikasie) in die afgelope 12 maande. Meeste onderwysers (81.6%, n=29) onderskat die proporsie van meisies wat kliniese evaluasie benodig en 71.1% (n=27) onderskat die omvang van huidige gewigsverlies-pogings. Byna alle (97.3%, n=37) onderwysers het die behoefte erken dat versteurde houdings en eetpatrone aangespreek moet word, maar slegs 34,2% (n=13) beskou die skool as die geskikte plek daarvoor en sal bereid wees om deel te neem en klastyd af te staan. Gevolgtrekkings: Die teenwoordigheid van abnormale houding teenoor eet onder Joodse vroulike adolessente in Suid-Afrika word vir die eerste keer in hierdie studie gedokumenteer. Die prevalensie val binne die boonste deel van die reikwydte van koerse wat gerapporteer is in studies oor adolessente meisies in Suid-Afrika en die buiteland. Dieet en pogings tot gewigsverlies is algemeen in hierdie populasie en stem ook ooreen met die bevindinge van internasionale studies. Dit is die eerste studie wat onderwysers se bewustheid meet ten opsigte van die eethoudings en gewigsverlies-gedrag van meisies wat skool bywoon waar hul onderrig gee. Die onderwysers wat deelgeneem het aan hierdie studie was nie ten volle bewus van die mate waartoe eet-verwante kwessies vroulike leerlinge affekteer nie. Boonop blyk daar weerstand te wees teenoor die fasilitering van, en deelname aan 'n skoolprogram wat hierdie kwessies aanspreek. Verdere kwalitatiewe ondersoeke hiervan kan moontlik waardevolle insig bied.
