Improving the Reporting of Young Children's Food Intake: Insights from a Cognitive Interviewing Study with Mothers of 3-7-Year Old Children.

Short food questions (SFQ) allow for rapid reporting of food intake across a variety of settings but are limited by poor validity and reliability. Understanding the recall process used by parents to report children’s food intake can improve question design and psychometric performance. This study aimed to improve understanding of how parents report children’s dietary intake using SFQ. Semi-structured, cognitive interviews were conducted with 21 mothers of 3–7-year-old children. Mothers were asked to ‘think-aloud’ while answering SFQ about their child’s food intake. Thematic analysis identified themes relating to parent’s question and answer process and barriers to recall. Information retrieval strategies focused on ‘use-of-time’ and ‘sphere of food provision’ and differed for core versus unhealthy foods. Recall of routine and home food provision were used to report core food intake, whereas recall of special occasions and food provision outside the home guided recall of discretionary foods. Mothers utilize different recall strategies for core and discretionary foods based on use of time and the sphere of food provision. The ease of reporting children’s dietary intake may be improved by utilizing a shorter recall time frame, clear and direct question wording, and use of food examples and recall prompts.

Parenting styles and the dietary intake of pre-school children: a systematic review

Objective: The prevalence of childhood overweight and obesity has been increasing globally, with poor diet a key contributor. Parents play an influential role over the food intake of young children. This review explores whether parenting styles (authoritative, authoritarian, permissive and disengaged) or parenting dimensions (warmth and control) are associated with pre-school children’s dietary intake.Design: Following the PRISMA guidelines, a systematic search of six electronic databases was conducted. Included articles were based on children aged 2-5 years and reported associations between parenting styles or dimensions and children’s food intake. Two independent reviewers extracted the data and assessed the quality of the articles.Main outcome measures: Pre-school children’s dietary intake.Results: Seven articles met the inclusion criteria. Six of the seven articles found evidence of at least one association between parenting styles or parenting dimensions and children’s dietary intake. Several different measurement tools were used to identify parenting styles (n = 3) and dietary intake (n = 6), with reliability and validity reported in varying ways. The quality score of the articles ranged from 33% to 58%.Conclusion: Overall, an authoritative parenting style or higher levels of warmth appear to be associated with healthier dietary intakes among pre-school children.

Colour as a cue to eat: Effects of plate colour on snack intake in pre-school children

Environmental cues, such as the colour of food and dishware, have been shown to influence food and drink consumption in adult populations. This proof of concept study investigated whether plate colour could be utilised as a strategy to reduce intake of high energy density (HED) snacks and increase intake of low energy density (LED) snacks in pre-school children. In a between and within-subjects design, children were randomly assigned to either a control group (no colour message) or intervention group (received a colour message: red = stop, green = go) and were provided a snack at nursery on three occasions on differently coloured plates (red, green, white), for each snack type (HED, LED). Snack intake, colour preference, colour association, and anthropometrics were recorded for each child. The results showed that there was no effect of group (control vs intervention) on HED (p = 0.540) and LED intake (p = 0.575). No effect of plate colour on HED (p = 0.147) or LED snack intake (p = 0.505) was evident. Combining red and green plates for a chromatic versus achromatic comparison showed that there was no significant effect of chromatic plate on HED (p = 0.0503) and LED (p = 0.347) intakes. Despite receiving a brief learning intervention, the use of plate colour was found in the present study to be an ineffective strategy to control snack food intake in pre-school aged children. Rather, we suggest that food intake in young children may best be predicted by portion size, energy density and eating behaviour traits.

Playing with food: The effects of food pre-exposure on consumption in young children

Recent research has shown that pre-exposure to food can lead to reduced subsequent consumption in older children and adults when they focus on a task with a non-eating goal during exposure. One assumption is that the reduced consumption is a consequence of self-regulation that helps to concentrate on the task. Because self-regulatory mechanisms are still under development in young children, we studied the effects of food pre-exposure in young children under the age of six (N = 81). Children played a memory game with real sweets (food pre-exposure) or similar non-food stimuli (non-food pre-exposure) and we measured their subsequent food consumption. In contrast to the findings with older children in other studies, we found that pre-exposure led to an increase (not a decrease) in subsequent consumption. This effect was stronger among children with a higher BMI. Food exposure paradigms might not lead to the desired reduction in food intake in young children, whose BMI is positively associated with food reactivity. Thus, food exposure must continue to be considered a strong risk factor for obesity in young children.

Determining Factors and Critical Periods in the Formation of Eating Habits: Results from the Habeat Project

Background: Eating habits form early during childhood and are likely to track until the beginning of adulthood. Thus, understanding the formation of eating habits is important. Consequently, the population targeted in the European project Habeat comprised infants and young children up to 6 years of age. Summary: Habeat mainly focused on the qualitative dimension of eating habits with a particular attention on vegetables and to a lesser extent on fruit. Food intake of young children was also studied in 2 challenging situations where overeating may occur and the relation between children's behaviour and feeding parental practices was examined. Key Messages: Habeat found evidence that breastfeeding may facilitate the consumption of vegetables and fruit and a greater variety of healthy foods in later childhood. Introduction of a variety of vegetables at the beginning of the complementary feeding period increases later acceptance of novel foods. Repeated exposure is a powerful mechanism to increase children's intake of a novel vegetable in infants and young children. Offering energy-dense snacks before or after meals should be avoided. Moreover, food should be offered to children in response to their feelings of hunger, and not used as reward for a good behaviour or for any other reason.

A Mobile Phone Based Method to Assess Energy and Food Intake in Young Children: A Validation Study against the Doubly Labelled Water Method and 24 h Dietary Recalls.

Mobile phones are becoming important instruments for assessing diet and energy intake. We developed the Tool for Energy Balance in Children (TECH), which uses a mobile phone to assess energy and food intake in pre-school children. The aims of this study were: (a) to compare energy intake (EI) using TECH with total energy expenditure (TEE) measured via doubly labelled water (DLW); and (b) to compare intakes of fruits, vegetables, fruit juice, sweetened beverages, candy, ice cream, and bakery products using TECH with intakes acquired by 24 h dietary recalls. Participants were 39 healthy, Swedish children (5.5 ± 0.5 years) within the ongoing Mobile-based Intervention Intended to Stop Obesity in Preschoolers (MINISTOP) obesity prevention trial. Energy and food intakes were assessed during four days using TECH and 24 h telephone dietary recalls. Mean EI (TECH) was not statistically different from TEE (DLW) (5820 ± 820 kJ/24 h and 6040 ± 680kJ/24 h, respectively). No significant differences in the average food intakes using TECH and 24 h dietary recalls were found. All food intakes were correlated between TECH and the 24 h dietary recalls (ρ = 0.665–0.896, p < 0.001). In conclusion, TECH accurately estimated the average intakes of energy and selected foods and thus has the potential to be a useful tool for dietary studies in pre-school children, for example obesity prevention trials.

An After‐School Snack of Raisins Lowers Cumulative Food Intake in Young Children

Snacks are an important part of children's dietary intake, but the role of dried fruit on energy intake in children is unknown. Therefore, the effect of ad libitum consumption of an after-school snack of raisins, grapes, potato chips, and chocolate chip cookies on appetite and energy intake in twenty-six 8- to 11-y-old normal-weight (15th to 85th percentile) children was examined. On 4 separate weekdays, 1 wk apart, children (11 M, 15 F) were given a standardized breakfast, morning snack (apple), and a standardized lunch. After school, children randomly received 1 of 4 ad libitum snacks and were instructed to eat until "comfortably full." Appetite was measured before and 15, 30, and 45 min after snack consumption. Children consumed the least calories from raisins and grapes and the most from cookies (P < 0.001). However, weight of raisins consumed was similar to potato chips (about 75 g) and lower compared to grapes and cookies (P < 0.009). Raisins and grapes led to lower cumulative food intake (breakfast + morning snack + lunch + after-school snack) (P < 0.001), while the cookies increased cumulative food intake (P < 0.001) compared to the other snacks. Grapes lowered appetite compared to all other snacks (P < 0.001) when expressed as a change in appetite per kilocalorie of the snack. Ad libitum consumption of raisins has potential as an after-school snack to achieve low snack intake prior to dinner, similar to grapes, compared to potato chips, and cookies in children 8 to 11 y old.

A Review of the Health Benefits of Raisins

There have been relatively few studies conducted on the health benefits of dried fruits; however, over the past few years there have been many advances regarding the health benefits of raisins. Williamson and Carughi (2012) recently reviewed the polyphenol content and health benefits of raisins. The review showed that raisins contain significant amounts of the flavonols quercetin and kaempferol and the phenolic acids caftaric and coutaric. Both quercetin and kaempferol are found in raisins as glycosides. Although the bioavailability of these compounds has not been studied in raisins, they have been shown to be well absorbed from other foods. These compounds may be responsible for some of the health benefits that have been reported with raisin consumption (Williamson and Carughi 2012). During the dehydration of grapes to raisins there is a significant loss of specific phenolic acids and polyphenols. However, total antioxidant capacity and total polyphenol contents remain relatively unchanged. Moreover, when equivalent amounts of grapes are fed either as fresh grapes, raisins, or wine (non-alcoholic) similar amounts of certain phenolic acid metabolites are detected in the urine. Thus, phenolic acids appear to be more bioavailable in raisins than in grapes and white wine (Murphy 2012). A webcast regarding the Emerging Health Benefits of Traditional Dried Fruit was presented on July 18, 2012 as a satellite session to the 2012 Institute of Food Technologists (IFT) annual meeting. This webcast was designed to review the latest research on the health benefits of raisins. The webcast included research studies regarding raisins and dental health by Allen Wong, D.D.S., Ed.D; heart disease and glycemic response by James Anderson, MD; satiety and energy intake by Barkha Patel, M.Sc.; and phytonutrient content by Rui Hai Liu, M.D., Ph.D. This supplement includes review papers from this webcast. Grape consumption, in the form of fresh grapes, raisins, and 100% grape juice, is associated with an overall increase in diet quality and nutrient intake. In “Improved Diet Quality and Increased Nutrient Intakes Associated with Grape Product Consumption by U.S. Children and Adults: National Health and Nutrition Examination Survey 2003–2008”, Debra Keast compared the diet quality of grape consumers (GC) with non-grape consumers (NGC). Compared to NGC, GC had higher intakes of total and whole fruit along with lower intakes of solid fat and added sugars. The grape consumers had higher intakes of several key nutrients including dietary fiber, vitamin A, vitamin C, calcium, and potassium. In “Raisins and Oral Health”, Allen Wong, D.D.S., Ed.D, discussed how current research shows some evidence that raisins may not contribute to dental caries, contrary to traditional thought. This paper reviews new findings with regards to raisins and the three conditions that are thought to contribute to the formation of dental caries; low oral pH, adherence of food to teeth, and biofilm (bacterial) behavior. The consumption of raisins has also been shown to improve blood glucose control and reduce risk for cardiovascular disease. In “Raisin Consumption by Humans: Effects On Glycemia and Insulinemia and Cardiovascular Risk Factors” James Anderson, M.D. reviews past research on the cardiovascular protective effects of raisins including their effects in reducing oxidized LDL (Barnes and others 2011) and reducing low-density lipoprotein (LDL) cholesterol (Puglisi and others 2008). The effect of the regular consumption of raisins on reduction of post-prandial glucose levels, HgbA1C, and blood pressure are also reviewed (Bays and others 2012 a, b) In “An After-School Snack of Raisins Lowers Cumulative Food Intake in Young Children” Barkha Patel, M.Sc. discusses how raisins as an after-school snack lower cumulative intake over the day compared to other snacks (potato chips, cookies). The researchers also discussed how the consumption of raisins before lunch can reduce calorie consumption at the subsequent meal. Researchers suggest that raisins as a snack may support appetite and weight control, thus reducing the risk for obesity (Patel and others 2011). In “Dietary Bioactive Compounds and Their Health Implications”, Rui Hai Liu, M.D., Ph.D, covered current research on phytochemicals in raisins and the prevention of chronic disease. Evidence suggests that health benefits of raisins may be attributed to the synergistic effects of phytochemicals present in whole foods.

Television watching and the emotional impact on social modeling of food intake among children

The main goal of this study was to test whether exposure to happy, neutral, or sad media content influences social modeling effects of (snack) food intake in young children. The study was conducted at 14 Dutch urban and suburban primary schools. The participants (N=112) were asked to watch a movie with a same-sex normal-weight confederate who was instructed to eat either nothing or a standardized amount of snack food (10 chocolate-coated peanuts). The study involved a 3 (movie clips: happy, neutral, and sad)×2 (peer’s food intake: no intake versus a standardized intake) between-participants design. A significant interaction between the movie clip condition and intake condition was found (F2,102=3.30, P=.04, Cohen’s f2=.20). Positive as well as negative emotions were found to lead to adjustment to the intake of a peer, as compared to that of children in the neutral movie condition. The findings suggest that children eat more mindlessly when watching an emotional movie and, therefore, respond more automatically to a peer’s food intake, whereas children may be less susceptible to a peer’s intake while watching a neutral movie. As young children are not in the position to choose their food consumption environment yet, parents and schools should provide consumption settings that limit eating in front of the television.

Assessment tools of energy balance‐related behaviours used in European obesity prevention strategies: review of studies during preschool

Valid and reliable measures of energy balance-related behaviours are required when evaluating the effectiveness of public health interventions aiming at prevention of childhood obesity. A structured descriptive review was performed to appraise food intake, physical activity and sedentary behaviour assessment tools used in obesity intervention strategies targeting mainly preschool children across Europe. In total, 25 papers are described, addressing energy balance-related behaviours as study outcomes and targeting individuals or clusters of individuals at school- or home-based environment. Parentally reported food records and 24-h recalls were commonly used to assess food intake. Subjective levels of physical activity and sedentary behaviour were commonly accessed via parentally reported questionnaires. Accelerometry was used to obtain objective measures of physical activity. Insufficient evidence of tool evaluation was provided. When feasible, food records and accelerometry are recommended as the most appropriate methods to assess food intake in young children. Sedentary behaviour could be assessed via questionnaires that include key indicators of sedentarism and are able to differentiate individual practices. The choice of methodology for the assessment of specific intervention effects should be equally balanced between required accuracy levels and feasibility, and be guided by the intervention targets.

Influences of the Family and Childcare Food Environments on Preschoolers' Healthy Eating

THE STUDY EXTENDS CAMPBELL, Crawford and Ball's (2006) findings that the family food environment influences eating in children by examining whether young children's food intake at home is also influenced by the childcare food environment. Participants were 103 parents of children aged three to five years who attended childcare centres in South Australia. Centres had either obtained the ‘Start Right Eat Right’ (SRER) nutrition certification; an award associated with compliance with the government's healthy eating guidelines, or had not attained certification with SRER. Participating parents completed a questionnaire measuring the family food environment as well as a food frequency questionnaire that recorded children's intake of ‘healthy’ and ‘unhealthy’ foods. Parents of children at SRER centres reported that their children ate more healthy food choices at home, as measured using the food frequency questionnaire, than parents of children attending non-SRER accredited centres. Pressure to eat, parental modelling, monitoring and perceptions of adequacy of a child's diet were all associated with children's eating. The results suggest that childcare centres, in addition to the family environment, can have an important role to play in developing healthy dietary choices in preschool children.

Maternal encouragement to be thin moderates the effect of commercials on children's snack food intake

The present study experimentally tested the effects of adult targeted food commercials (energy-dense and light food products) on actual snack food intake in young children while watching television. Furthermore, the moderating role of maternal behaviors was investigated. The children (N=121, aged between 8 and 12 years) were exposed to a neutral movie that was interrupted by two commercial breaks. These breaks contained commercials promoting either energy-dense foods, low energy versions of the same energy-dense foods (light food commercials), or neutral commercials aimed at adults. Snack food intake during watching television was measured. Children filled out questionnaires and were weighed and measured afterwards. Children who perceived maternal encouragement to be thin ate slightly more when exposed to energy-dense food commercials and especially when exposed to light food commercials than when exposed to neutral commercials. In contrast, children who perceived no maternal encouragement to be thin ate more when exposed to neutral commercials than when exposed to either energy-dense food commercials or light food commercials. These findings suggest that exposure to adult targeted light food cues produced disinhibition in children who experienced maternal encouragement to be thin, resulting in elevated snack food intake.

Development and Reliability of an Observation Method to Assess Food Intake of Young Children in Child Care

To our knowledge, a direct observation protocol for assessing dietary intake among young children in child care has not been published. This article reviews the development and testing of a diet observation system for child care facilities that occurred during a larger intervention trial. Development of this system was divided into five phases, done in conjunction with a larger intervention study; (a) protocol development, (b) training of field staff, (c) certification of field staff in a laboratory setting, (d) implementation in a child-care setting, and (e) certification of field staff in a child-care setting. During the certification phases, methods were used to assess the accuracy and reliability of all observers at estimating types and amounts of food and beverages commonly served in child care. Tests of agreement show strong agreement among five observers, as well as strong accuracy between the observers and 20 measured portions of foods and beverages with a mean intraclass correlation coefficient value of 0.99. This structured observation system shows promise as a valid and reliable approach for assessing dietary intake of children in child care and makes a valuable contribution to the growing body of literature on the dietary assessment of young children.

Beyond-brand effect of television (TV) food advertisements/commercials on caloric intake and food choice of 5–7-year-old children

Food advert exposure has been shown to influence calorie intake and food choice in 9-11 year olds. However, little is known about the effect of food advertisements on feeding behaviour in younger children. Therefore, we conducted a study with 93 children aged 5-7 years, 28 of whom were over weight or obese. The children were exposed to 10 non-food adverts and 10 food adverts in a repeated measures design. Their consumption of sweet and savoury, high and low fat snack foods, and fruit were measured following both sessions. Food advert exposure produced a significant increase in total food intake in young children. The collection of recognition data was incomplete. These data replicate previous findings in that exposure to food adverts increases food intake in all children, but recognition of food adverts is related to body mass index (BMI). Beyond their effects on brand choice, exposure to food advertisements (commercials) promotes over-consumption in younger children.

Effect of an Integrated Child Nutrition Intervention on the Complementary Food Intake of Young Children in Rural North Viet Nam

Forty-two percent of Vietnamese children are stunted by two years of age. Since 1990, Save the Children Federation/US (SC) has implemented integrated nutrition programs targeting young children. We evaluated the effect of SC's nutrition program on the complementary food intake of young rural Vietnamese children. Using a longitudinal, prospective, randomized design, we followed 238 children (119 each from intervention and comparison communes) age 5 to 25 months old for six months with a re-survey at 12 months. We gathered 24-hour recall data at baseline and at months 2, 4, 6, and 12. Dietary energy intake was calculated using the 1972 Vietnamese food composition table. Key outcomes were daily frequency of consuming intervention-promoted food and non-breastmilk liquids and food, daily quantity of non-breastmilk liquids and food consumed, daily energy intake, and proportion of children meeting daily median energy requirements. Young rural children exposed to SC's program consumed intervention-promoted, and any, foods more frequently, ate a greater quantity of any food, consumed more energy, and were more likely to meet their daily energy requirements than comparison children. Some effects were only observed during the intensive intervention period; others persisted into or were evident only at the 12-month follow-up, approximately four months after program completion. Based on the mothers' reports, the intervention did not apparently compromise breastfeeding prevalence or frequency. The intervention improved children's food and energy intake and protected them from declining as rapidly as comparison children in meeting their energy requirements.

Effects of multivitamin–multimineral supplementation on appetite of stunted young Beninese children

In the developing world, food intake of young children is often insufficient for growth. Reduced appetite due to several factors including micronutrient deficiencies might be an explanation. We hypothesized that a multivitamin–multimineral supplementation will improve appetite of stunted children in south of Benin. Multivitamin–multimineral supplements (VITALIA-tablets) contain 11 vitamins and 8 minerals. Stunted children (Ht/Age Z score<−2) of 17–32 months old were randomly assigned to multivitamin–multimineral (n=48) or placebo (n=53) group. Supplementation was daily and supervised throughout 6 weeks. Knee-heel length, length, weight, arm circumference and appetite were assessed once a week for the three weeks preceding and the three weeks following the six-week intervention period. Growth was additionally assessed 4 months after intervention. Each appetite test day, morbidity data and mother's report on child's appetite throughout the preceding day were recorded. Reported appetite, intake of test food and knee-heel length increased after supplementation in both groups (p<0·05), but were not different between groups. Growth was similar 4 months after the intervention. Morbidity was comparable in both groups before as well as after supplementation. We conclude that 6-week multivitamin–multimineral supplementation alone failed to improve appetite and growth of stunted young children.

Effects of restrictive and self-selected feeding on preschool children's food intake and waste at snacktime

Regulating young children's food intake is common practice in child care facilities. Many caregivers fear that children will overeat or waste food if allowed to select their own portions. The purpose of this study was to compare food intake and waste of preschool children at snacktime when given one portion of snack and when allowed to self-select their snack amount. Subjects were 20 3-year-olds and 20 4-year-olds enrolled in a university preschool. For the 29 days of restrictive feeding, children were offered only one portion of snack. For the 25 days of self-selected feeding, children could eat as many portions as they wanted. Based on a 2 × 2 factorial analysis of variance (ANOVA), there was a significant interaction of class and feeding method. During self-selected feeding, the 4-year-old group increased their intake to a greater extent than the 3-year-old group. The number of portions wasted was not significantly different for the two feeding methods; however, the younger children wasted significantly more than the older children. These results indicate that preschool children in group settings will eat more than one portion at snack time when they are allowed to self-select their intake without significantly increasing the amount they waste.
