Objective: To identify parental child-feeding strategies that may increase children's fruit or vegetable intake, since the relationship between these strategies and children's intake has never been investigated for fruit and vegetables as two separate food groups. Design: A survey study, where parents provided information about their practices in relation to feeding their children and about their own and their children's fruit and vegetable intake. Children completed a preference questionnaire about fruit and vegetables. To find underlying parental child-feeding strategies, factor analysis was applied to parents' practices in relation to fruit and vegetables separately. Regression analysis was used to predict the effect of these strategies on children's fruit and vegetable intake. The impact of the strategies was further analysed by estimating children's intake based on the frequency of use of specific strategies. Setting: The study was conducted at three primary schools in The Netherlands. Subjects: A total of 259 children between 4 and 12 years old and their parents (n 242). Results: Parents used different strategies for fruit as compared with vegetables. The vegetable-eating context was more negative than the fruit-eating context. Parental intake and presenting the children with choice were positive predictors of children's intake of both fruit and vegetables. The intake difference based on frequency of use of the strategy 'Choice' was 40 g/d for vegetables and 72 g/d for fruit (P , 0?001). Conclusions: Future interventions should focus on presenting children with choice during fruit-and vegetable-eating situations, since this is a powerful strategy to stimulate children's fruit and vegetable intake.

“…Despite difficulties in sensory analysis and consumer studies with children, it is extremely important to obtain information about children's liking for foods, because it can provide valuable data for the development of new products for children (Ward et al 1999;Guinard 2001;Thybo et al 2004). Central location test is the most frequently used method for sensory acceptance (Boutrolle et al 2005).…”

Quality characteristics and consumer acceptance of a high fish protein puffed corn-fish snack

Corn snack fortified with 7% fish protein powder made from saithe (Pollachius Virens) surimi was selected by expert panel from industry for consumer studies in Iran and Iceland. They hedonically screened products with 3%, 5%, 7% and 9% fish protein powder. Snack containing 9% fish protein powder (FP) had significantly lower liking for odour, texture, flavour, and overall acceptability than the other three prototypes. Snacks fortified with 3%, 5%, and 7% FP had similar sensory attributes. Therefore, snack with the highest level of FP (7%) was selected for acceptance tests. It was seasoned with cheese powder, vegetable oil, salt, and colorant. The amount of protein, moisture, fat, ash and salt in fortified corn snack (FCS) was 12%, 2%, 31%, 3%, and 2% respectively. Consumers' acceptance was studied using a central location test method. Consumers were 6-16 years old children in two communities (Iceland and Iran). They liked FCS but Iranian children favoured it more than Icelandic children. Majority of parents of the participants expressed their willingness to choose this product when buying snacks.

“…32 Adaptation of the sensory perception module was compulsory after the pretest. This task was unsuitable for kindergarten children, even though Guinard 33 suggests that children between 2 and 4 years of age can consistently perform a paired preference test, similar to that applied in IDEFICS. In our experience, children 5 years of age can detect diverse tastes but cannot give repeatable results: the taste perception in this age group is inherently variable over longer periods of time.…”

“…34,35 During the pretest, we found that children over 6 years of age performed discrimination tasks such as the paired comparison more reliably, which has been reported previously. 33 For this reason, we decided to restrict this test to school children.…”

Design and results of the pretest of the IDEFICS study

Background: During the preparatory phase of the baseline survey of the IDEFICS (Identification and prevention of dietary-and lifestyle-induced health effects in children and infants) study, standardised survey procedures including instruments, examinations, methods, biological sampling and software tools were developed and pretested for their feasibility, robustness and acceptability. Methods: A pretest was conducted of full survey procedures in 119 children aged 2-9 years in nine European survey centres (N per centre ¼ 4-27, mean 13.22). Novel techniques such as ultrasound measurements to assess subcutaneous fat and bone health, heart rate monitors combined with accelerometers and sensory taste perception tests were used. Results: Biological sampling, physical examinations, sensory taste perception tests, parental questionnaire and medical interview required only minor amendments, whereas physical fitness tests required major adaptations. Callipers for skinfold measurements were favoured over ultrasonography, as the latter showed only a low-to-modest agreement with calliper measurements (correlation coefficients of r ¼ À0.22 and r ¼ 0.67 for all children). The combination of accelerometers with heart rate monitors was feasible in school children only. Implementation of the computer-based 24-h dietary recall required a complex and intensive developmental stage. It was combined with the assessment of school meals, which was changed after the pretest from portion weighing to the more feasible observation of the consumed portion size per child. The inclusion of heel ultrasonometry as an indicator of bone stiffness was the most important amendment after the pretest. Discussion: Feasibility and acceptability of all procedures had to be balanced against their scientific value. Extensive pretesting, training and subsequent refinement of the methods were necessary to assess the feasibility of all instruments and procedures in routine fieldwork and to exchange or modify procedures that would otherwise give invalid or misleading results.
