Assessment of nutrient and water intake among adolescents from sports federations in the Federal District, Brazil.

Abstract: Adolescents aged 11-14 years (n 326), belonging to organized sports federations in the Federal District, Brazil were interviewed. Subjects (n 107) provided four non-consecutive days of food consumption and 219 subjects provided two non-consecutive days of intake. The objective was to assess their nutrient and water intake according to dietary reference intake values and their energy and macronutrient intake by sex and sports groups they were engaged in: endurance, strength-skill or mixed, according to the guidelines established by the American College of Sport Medicine (ACSM). Dietary data were corrected for intra-individual variation. Total energy expenditure was higher among endurance athletes (P < 0.001) following their higher training time (P < 0.001) when compared to adolescents engaged in strength-skill or mixed sports. Total energy intake was only significantly higher among endurance-engaged females (P = 0.05). Protein intake of males was above the guidelines established by the ACSM for all sports groups. All male sport groups fulfilled the intake levels of carbohydrate per kg body weight but only females engaged in endurance sports fulfilled carbohydrate guidelines. Intakes of micronutrients with low prevalence of adequate intake were: vitamins B1, E and folate, magnesium and phosphorus. Few adolescents ( < 5 %) presented adequate intake for calcium, fibre, drinking water and beverages. For micronutrients, prevalence of adequacies were lower for females than males, except for liquids and water. Nutrition guidance is needed to help adolescents fulfil specific guidelines of macronutrient intake for their sports and to improve their intake of micronutrients and water. Special attention should be given to female adolescent athletes.

Energy and nutrient intake of Swiss women aged 75-87 years.

Abstract: Objective Reliable data about the nutrient intake of elderly noninstitutionalized women in Switzerland is lacking. The aim of this study was to assess the energy and nutrient intake in this specific population. Subjects The 401 subjects were randomly selected women of mean age of 80.4 years (range 75–87) recruited from the Swiss SEMOF (Swiss Evaluation of the Methods of Measurement of Osteoporotic Fracture Risk) cohort study. A validated food frequency questionnaire (FFQ) was submitted to the 401 subjects to assess dietary intake. Results The FFQ showed a mean daily energy intake of 1544 kcal (±447.7). Protein intake was 65.2 g (±19.9), that is 1.03 g kg−1 body weight per day. The mean daily intake for energy, fat, carbohydrate, calcium, magnesium, vitamin C, D and E were below the RNI. However, protein, phosphorus, potassium, iron and vitamin B6 were above the RNI. Conclusion The mean nutrient intake of these free living Swiss elderly women was low compared with standards. Energy dense foods rich in carbohydrate, magnesium, calcium, vitamin D and E as well as regular sunshine exposure is recommended in order to optimise dietary intake.

Can nutrition counselling be more behavioural? Lessons learned from dietary management of cystic fibrosis

Abstract: Cystic fibrosis (CF) is a genetically-inherited disorder that results in energy imbalance. Undernutrition is common in children with CF and associated with poor health outcomes. To ensure optimal growth and nutrition, children with CF are recommended to consume 120-150 % of the recommended daily allowance (RDA) for energy, but most studies show they typically are only able to achieve 100 % of the RDA. While biological factors clearly contribute to poor dietary adherence, recent studies have documented behavioural and environmental barriers to adherence that includes parent-child interaction at mealtimes. While not 'abnormal', parent behaviours such as paying increased attention to the child in the form of coaxing, commanding and feeding when the child is engaged in behaviours incompatible with eating (food refusal, talking, leaving the meal) may serve to reinforce these child non-eating behaviours. Thus, dietary counselling alone, albeit necessary, is typically insufficient because of failure to specifically address these behavioural and environmental barriers to dietary treatment. Behavioural intervention that targets both nutrition education and behavioural management has been found to be effective in achieving an average increased energy intake of 4200 kJ (1000 kcal)/d and weight gain of 1.48 kg over 9 weeks in children with CF. This intervention utilizes self-monitoring, goal setting and shaping to structure the delivery of treatment. It also teaches parents to utilize child behaviour-management techniques to motivate children to increase their energy intake. These behavioural strategies include differential attention (praising and ignoring), contingency management and behavioural contracting. The potential application of these techniques to dietary counselling is suggested.

Complementary feeding practices and nutrient intake from habitual complementary foods of infants and children aged 6-18 months old in Lusaka Zambia.

Abstract: Poor quality complementary foods with low nutrient density and inappropriate feeding practices have been identified among the major causes of malnutrition in young children. In many developing countries, complementary foods are introduced too early or too late and the quality and quantity of the foods are insufficient, leading to a great risk of nutritional deficiencies during the second half of infancy. Most of the habitually used complementary foods in developing countries are unfortified cerealbased gruels characterised by low energy and nutrient density and are often inadequate in iron, zinc and pyridoxine and in some populations may be deficient in riboflavin, niacin, calcium, thiamine, folate, ascorbic acid and vitamin A. The aim of this study was to establish current complementary feeding practices of mothers/caretakers living in a medium income urban community in Lusaka, Zambia. The study was the first phase of a larger study designed to develop improved complementary foods based on already-in-use cereals and legumes for the improvement of infant health in urban settings characterised by high HIV prevalence. Complementary feeding practices and nutrient intakes of children 6-18 months old in Lusaka were assessed by qualitative and quantitative methods. Themes generated from three focus group discussions (9 health workers, 7 mothers and 8 fathers) were used to design a semi-structured questionnaire to interview 34 mothers, 20 of whom were observed for 12 hours at home and their infant's dietary intake measured by 12-h weighed food record and 24-h recall, (assuming medium breast milk intake). The results showed that although mothers had wide knowledge of optimal infant feeding, actual practices were constrained by food cost, maternal HIV status and time availability. Compared with the recommended daily allowance (RDA) at 6-8, 9-11 and 12-18 months of age, the daily nutrient intakes were 88%, 121% and 94% for energy; 33%, 52% and 59% for iron and 30%, 33% and 38% for calcium, respectively. Fortification of complementary foods is necessary to meet infants' needs for iron and calcium. Keywords : Complementary feeding, infants, iron, Zambia. AJFAND Vol. 8 (1) 2008 pp. 28-47
