DIETARY INTAKES AND PHYSICAL ACTIVITY IN A SAMPLE OF CHILDREN IN SASKATOON
Notice bibliographique
Résumé
Diet and physical activity are modifiable human behaviors and play important roles in children's health. Almost all diet and physical activity studies in children have examined diet or physical activity separately and have not looked at these two factors together in the same sample of children. This study was carried out to investigate both diet and physical activity in a group of children to better understand the relationship of diet and physical activity, as well as to collect healthy reference data for future studies in clinical child populations. Fifty children (26 females and 24 males) ages ranging from 6 to 15 years, living in Saskatoon were recruited for the study. Mean ages, heights, weights, head circumferences and tricep skinfold thicknesses of male and female children were not significantly different to each other. Male children had significantly higher energy, carbohydrate, protein, and fat intakes. Energy intakes of males and females were low compared to literature values. Thirty one (62%) children were below adequate intake (AI) for calcium and the number of children below AI for vitamin D was 16 (38%). Thirty two (64%) children were below estimated average requirement (EAR) for vitamin E. There was no difference in the level of physical activity between male and female children when using Physical activity questionnaire for older children (PAQ-C), activity diary, and Caltrac. Twenty percent of children was obese and this was similar to the North American reported values. Both males (-192 ± 610 kcal) and females (- 410 ± 393 kcal) had a apparent negative energy balance with a significantly greater negative balance observed in females (p<0.05). Twenty children (40%) were underreporters at the energy intake (EI) to the estimated resting energy expenditure ratio of less than 1.1, the cut off level. Underreporters had significantly higher mean age (11.1 ± 2.9 years) and BMI (18.8 ± 2.8 kg/m') than normal reporters (8.7 ± 2.1 years and 16.28 ± 2.5 kg/m2). Also, underreporters' mean energy intakes (1258 ± 193 kcal) and physical activity (PAQ-C) rating: 2.69 ± 0.62) were lower than normal reporters (1610 ± 372 kcal and PAQ-C rating: 3.03 ± 0.51) . No association was found between underreporting and children's sex or BMI. The difference in male and female children's nutrient intakes, mainly energy intake, was due to their sex differences and cannot be attributed to their underreporting, anthropometry or levels of physical activities. Underreporting would have reduced apparent mean energy and other nutrient intakes. The level of nutrient intakes and physical activity were adequate except inadequacies observed in relation to calcium, vitamin D, vitamin A, and vitamin E intakes. Increase in vegetable and fruit, and milk products up to the Canada's Food Guide's minimum recommended levels is recommended to reduce the vitamin D, vitamin A, and vitamin E inadequacies.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
