Impact of nutrition messages on children's food choice: pilot study.

This pilot study tested the influence of nutrition message framing on snack choice among kindergarteners. Three classrooms were randomly assigned to watch one of the following 60s videos: (a) a gain-framed nutrition message (i.e. the positive benefits of eating apples) (n=14); (b) a loss-framed message (i.e. the negative consequences of not eating apples) (n=18); or (c) a control scene (children playing a game) (n=18). Following this, the children were offered a choice between animal crackers and an apple for their snack. Among the children who saw one of the nutrition message videos, 56% chose apples rather than animal crackers; in the control condition only 33% chose apples. This difference was statistically significant (chi2=7.56, p<0.01). These results suggest that videos containing nutritional messages may have a positive influence on children's short-term food choices.

Hedonic ratings and perceived healthiness in experimental functional food choices.

The associations of liking and perceived healthiness ratings between repeated food choices were studied in two experiments. Participants' snack bar (n=41, Experiment I) and beverage (n=60, Experiment II) choices among six product alternatives were monitored for 4 and 3 weeks, respectively. In Experiment I, participants were allowed to familiarise themselves with snack bar alternatives ("familiar assortment") prior to making choices. In Experiment II, the participants started making their beverage choices without familiarising themselves ("unfamiliar assortment"). In both experiments, the participants were divided into three groups according to their choice behaviour for each alternative: non-interested (0 choices), experimenters (1 choice) and potential frequent users (2 or more choices). In Experiment I, the overall difference between non-interested and potential frequent users of a product was 1.3 points in expected liking and 2.6 points in actual liking on a 7-point scale (ANOVA, p<0.001). In Experiment II, the overall differences in blind hedonic ratings between non-interested participants and potential frequent users of a product were within a range of 0.9 points (p<0.001). The difference was wider for expected liking ratings, 1.3 points (p<0.001). Neither the perceived healthiness of the samples nor the background attitudes could be consistently associated with the choices (Pearson's correlation coefficient).

Eating patterns and breakfast consumption in obese patients with binge eating disorder.

This study examined eating patterns and breakfast consumption, and their relationships to weight and binge eating, in obese individuals with binge eating disorder (BED). One-hundred seventy-three consecutively evaluated men (n=46) and women (n=127) with BED were administered semi-structured interviews and self-report measures to assess the frequency of meals and snacks eaten, as well as binge eating and eating disorder features. Overall, those who consumed more frequent meals, particularly breakfast, and snacks, weighed less. Breakfast, which was eaten on a daily basis by less than half of participants (n=74; 43%), was the least frequently eaten meal of the day. Participants (n=56; 32%) who ate three meals per day weighed significantly less, and had significantly fewer binges, than participants (n=117; 68%) who did not regularly eat three meals per day. Thus, eating more frequently, having breakfast and consuming three meals every day, have potentially important clinical applications for the treatment of BED given that the effectiveness of specific interventions within treatments for BED are unknown, and that weight loss outcome for BED has been poor.

Development of a perfusion reversed-phase high performance liquid chromatography method for the characterisation of maize products using multivariate analysis.

A perfusion reversed-phase high performance liquid chromatography (RP-HPLC) method has been designed to allow rapid (3.4 min) separations of maize proteins with high resolution. Several factors, such as extraction conditions, temperature, detection wavelength and type and concentration of ion-pairing agent were optimised. A fine optimisation of the gradient elution was also performed by applying experimental design. Commercial maize products for human consumption (flours, precocked flours, fried snacks and extruded snacks) were characterised for the first time by perfusion RP-HPLC and their chromatographic profiles allowed a differentiation among products relating the different technological process used for their preparation. Furthermore, applying discriminant analysis makes it possible to group the samples according with the technological process suffered by maize products, obtaining a good prediction in 92% of the samples.

Side effects of the Yuzpe regimen of emergency contraception and two modifications.

We investigated side effects after the standard Yuzpe regimen or two modifications: substituting norethindrone as the progestin or eliminating the second dose. We also examined the impact of taking either dose with food. Nearly two thirds of women reported at least one side effect, the majority of which were mild or moderate. Women in our study experienced more side effects after the second dose than after the first. Taking the first dose within 1 h of a meal or snack was associated with increased nausea and vomiting; taking the second dose within 1 h of a meal or snack was associated with decreased nausea and vomiting. A targeted approach to prophylactic antiemetic use could reduce the number of women given these drugs, and the number who experience unnecessary side effects. The impact of counseling on side effects should be further evaluated.

Development and implementation of a visual card-sorting technique for assessing food and activity preferences and patterns in African American girls.

OBJECTIVE: Card-sorting tasks for assessing food and activity preferences and patterns among African American girls were developed. Associations among food preference and intake frequency, activity preference and frequency, and body mass index were examined. DESIGN: Participants completed newly developed card-sorting tasks assessing food and activity preferences and patterns. Height and weight were measured. SUBJECTS/SETTING: Ninety-six 8- to 10-year-old African American girls from schools and community centers in Minneapolis-St. Paul. MAIN OUTCOME MEASURES: Preference and frequency data for 64 foods/beverages and 34 activities. STATISTICAL ANALYSES: Frequencies for food and activity preference and frequency categories were computed. Pearson correlations among food and activity preference, frequency, and body mass index were computed. RESULTS: High-sugar (eg, fruit drinks, soda) and/or high-fat (eg, ice cream, cookies) foods were among the most popular and frequently consumed. Ninety-six percent of girls liked fruit drinks, with 35% consuming them "almost every day." Less-structured activities such as biking, games, jump rope, and dance were most popular. Biking was preferred by 85% of girls, with 48% biking "almost every day." Food preference and frequency categories were moderately correlated (r=0.30 to 0.58), as were activity preference and frequency (r=0.37 to 0.49). APPLICATIONS: The card-sorting tasks are useful tools for assessing food and activity preferences and patterns in girls. Obesity prevention programs for African American girls should include preferred activities such as dance, jump rope, and active play. Programs may also benefit from a focus on replacing high fat/high sugar snacks and sweetened beverages with low-fat, lower-calorie snacks and beverages (eg, fruit, vegetables, water).

Few differences found in the typical eating and physical activity habits of lower-level and upper-level university students.

Typical eating and exercise habits of a group of lower-level (freshmen/sophomores, n=144) and upper-level (juniors/seniors, n=114) students, 19 to 25 years of age, attending a midwestern university were compared. Both groups reported similar snacking practices, nonalcoholic beverage consumption, places of meal consumption, factors influencing food choices, duration and frequency of various types of physical activity, and places of physical performance, with few exceptions. Significant differences between groups were observed for typical afternoon snack consumption, frequency of eating in university cafeterias, typical time spent walking, typical frequency of performing other aerobic activities, and factors that most influenced their physical activity habits. Few differences existed in typical eating and physical activity habits of lower- and upper-level students.

"You had peas today?": a pilot study comparing a Head Start child-care center's menu with the actual food served.

This study explored the types of food served at a Head Start child-care center compared with that center's monthly menus. The study design was direct observation of the food provided by a Head Start center throughout the school day (Monday through Friday; 8:45 am to 2:30 pm) from January 4 to June 20, 2002, and analysis of this center's monthly menus. The numbers of meals directly observed for each type of meal service were: breakfast (n=96), lunch (n=95), and afternoon snack (n=78). These meals were compared with six monthly menus. Of the 269 meals and snacks compared, only three breakfast meals and an "ethnic day" matched the meals described on the provided menu. These findings illustrate that this center's menu was not consistently followed and therefore could not be used as an estimate of the preschoolers' intake or used as an educational or informational tool for parents/caregivers. Future research should verify how common these findings are among other Child and Adult Care Food Program child-care centers. Results may provide direction for development of the US Department of Agriculture's Child and Adult Care Food Program training for foodservice workers and educational materials focusing on menu development, appropriate substitutions, and the importance of using menus as a nutrition education tool.

Does eating during television viewing affect preschool children's intake?

The objective of this study was to examine the effects of television (TV) viewing on children's lunch and snack intake in one condition when the children watched a 22-minute cartoon video on TV (TV group), and in another without the TV (no TV group). Participants included 24 children and their parents, recruited from a university child-care center. Parents reported children's TV viewing habits at home. Overall, children ate significantly less snack and lunch in the TV condition compared with the no TV condition. However, children who reportedly watched more daily hours of TV and who had a higher frequency of meals eaten in front of the TV at home ate more lunch in the TV condition. TV viewing may either increase or reduce children's intake, depending on prior experience with eating during TV viewing.

Observations of parent-child co-shoppers in supermarkets: children's involvement in food selections, parental yielding, and refusal strategies.

The study aimed to collect descriptive information on the decision-making processes of adult shoppers around food purchases when young children are present. Anthropological field observations were conducted on adult-child grocery shoppers. Eleven supermarkets in the Minneapolis-St. Paul metropolitan region. A convenience sample (n = 142) of adult-child shoppers at 8 budget and 3 deluxe supermarkets located in diverse urban and suburban areas. Observations registered adult-child interactions over food selections, including parental yielding or refusal strategies and child engagement in shopping. Means and frequencies were calculated for food items considered. In 67 (50.4%) of the total 133 observations, a child initiated a request. Half (55.2%) of the requests were for sweets or snacks. Nearly half (47.8%) of adults yielded to the child's request. Brands and marketing techniques appeared to be a factor in 28.6% of selections. The most frequent adult refusals either provided an explanation or ignored the request. Adults yield to children's requests for sweets and snacks nearly as often as they refuse them. However, effective refusal strategies are used by many adults. Opportunities exist in the grocery store for adults to reinforce young children's interest in food and nutrition.

Neonatal handling alters feeding behavior of adult rats.

Stress during the neonatal period leads to a large number of behavioral and biochemical alterations in adult life. The aim of this study is to verify the effects of handling and tactile stimulation during the first 10 days of life on feeding behavior in adult rats. Litters were divided into (1). intact; (2). handled (10 min/day); and (3). handled and tactile stimulated (10 min/day). Procedures were performed on Days 1-10 after birth. When adults, rats were tested for ingestion of sweet and savory snacks. We also measured body weight, ingestion of standard lab chow, and consumption of water and 1% glucose and 1.5% NaCl solutions. Stressed rats (handling and handling+tactile stimulation groups) consumed more sweet (two-way ANOVA, P=.008) or savory snacks (P=.001) than intact ones. This effect was observed in males and females. There were no differences in body weight, ingestion of standard lab chow, water, or in the ingestion of sweetened or salty solutions between groups. The same animals were tested later in life (15 months of age), and the effect was still evident. We suggest that handling during the neonatal period leads to alterations in the CNS of rats, causing an increased ingestion of palatable food in adult life, and this alteration probably persists throughout the whole life.

Food hedonics and reinforcement as determinants of laboratory food intake in smokers.

Both the hedonic ratings and the reinforcing value of food have been considered to be determinants of food intake. The objective of this study was to compare the pleasurable ratings and the reinforcing value of food as determinants of energy intake. Seventy-four smokers were studied in food consumption and reinforcing value of food tasks prior to enrolling in a smoking-cessation treatment program. For the food consumption task, the participants tasted and consumed food ad lib from eight snack foods. The reinforcing value of the food task assessed how hard subjects would work for a preferred snack food. Results showed that food reinforcement was related to laboratory food intake, with those high in food reinforcement consuming significantly more calories (+114.4 kcal, P<.01) than did the participants low in food reinforcement. Food reinforcement was related to food intake for the preferred food as well as to total energy intake. Hedonics for the preferred food was related to food reinforcement but not to either measure of laboratory energy intake. In multiple-regression models, food reinforcement and the interaction of food reinforcement by sex were significant predictors of energy intake for the preferred food and for total energy intake, along with baseline hunger. In conclusion, energy intake in smokers in a laboratory setting is more strongly related to food reinforcement than to the hedonic ratings of food.

Fat intake and energy-balance effects.

This paper focuses on the effects of dietary fats or fatty acids on key targets of metabolic intermediates for body-weight control, i.e. satiety, thermogenesis, fat oxidation and body composition. With respect to sensory satiety, it appeared, e.g. that linoleic acid tasters showed a different mechanism for meal termination than non-tasters did. They stopped eating linoleic acid containing food based upon satiety, whereas the non-tasters stopped eating based upon the change in pleasantness of taste. Moreover, in the normal range of body mass index, an inverse relationship was shown between % 'tasters' and BMI. In a high fat diet vs. a low fat high protein high carbohydrate diet, metabolic satiety appeared to be continuously lower and correlated positively to diet-induced energy expenditure. However, with respect to the intermeal interval, satiety appeared to be more sustained following a high fat vs. a high CHO preload, resulting in a lower meal frequency. Covert fat replacement during breakfast by sucrose polyester was successful in combination with dietary restraint, yet overt fat replacement in snacks was successful in the dietary-unrestrained subjects, i.e. those who habitually ate snacks. With respect to fat oxidation, from a respiration-chamber experiment on the effects of diacylglycerol compared (DG) to triacylglycerol (TG) intake, it was concluded that consumption of DG increased fat oxidation and beta-hydroxy-butyrate levels, but did not affect energy metabolism or triacylglycerol level. Parameters of appetite were all lowered by DG compared to TG. With respect to body composition, the effects of 13 weeks CLA supplementation in overweight subjects during weight regain were assessed. Although CLA did not affect %body-weight regain, the regain of fat-free mass was increased by CLA, independently of %body-weight regain and physical activity, and as a consequence resting metabolic rate was increased. At the same time, appetite was reduced and satiety and fullness were increased. In conclusion, we also determined bright sports with respect to fat intake.

Manipulating establishing operations to promote initiations toward peers in children with autism.

This study examined the effects of manipulating establishing operations on the frequency of initiations of three children with autism toward peers with autism. The EO targeted was deprivation of preferred edibles, and the target initiation was a mand for the preferred snack. A reversal design was used to assess the effects of the EO conditions on frequency of initiations. Results indicated that when the EO was absent, no spontaneous initiations toward the peer occurred. Two participants required training sessions with an adult to transfer initiations toward peers. Once the EO had been established and was present, the participants initiated mands for the snack. Results are discussed in terms of implications for the use of establishing operations in language training for children with autism.

Coca-colonization of diets in the Yucatan.

Over the past three decades, tourism-based economic development has transformed social and economic conditions in the Yucatan Peninsula, Mexico. Mayan communities have become directly involved in the changing economy as the main source of inexpensive labor for construction and service jobs at tourism centers, and as sites of ecotourism and archeotourism. In this paper, we address how these macro-processes of change intersect locally with the commoditization of food systems, diets and nutrition in four Yucatec Mayan communities with differing relationships to the tourist economy. Yucatec Mayan diets have become increasingly dependent on purchased foods, and reflect a greater consumption of commercialized processed foods. Coca-Cola, an international icon of US culture, along with other local and internationally owned calorie-dense but nutrient-poor snack foods, is now a common element of Mayan diets, leading to what we call "coca-colonization." The consequences of this diet, likely exacerbated by the increased consumption of snack foods, include an apparent increase in overweight and obese adults as well as signs of growth stunting in children. The Maya we talked with recognize both the potential disruption that tourism brings to all aspects of their lives and the necessity of jobs that tourism creates to meet their families' basic needs.

Food consumption in rural and urban Tanzania.

Food consumption of 177 rural and 94 urban subjects (98 aged 12 years, 105 aged 35-44 years, and 68 aged 65-74 years) was studied in rural and urban Ilala district, Dar-es-Salaam, Tanzania, to characterize rural-urban differences in the meal and snack patterns and intakes of energy and nutrients. Food consumption of each subject was studied using 24 h dietary recall once during the rainy season and once during the dry season. Micro Nutrica PC database, expanded with East African food composition tables, was used in the nutrient intake analyses. All urban and 92% of rural subjects had three daily meals, and snacks were as commonly eaten in both areas of the survey. Foods of animal origin, e.g. meat and milk, were seldom used by the rural subjects. The WHO/FAO recommended minimal daily allowances of energy and protein were not reached by 26 and 15% of the rural subjects, respectively (10 and 4% of the urban subjects). Mean intake of folic acid by rural subjects was clearly below that of the urban subjects. Intakes of sucrose, mono- and disaccharides combined, polysaccharides, fibre and cholesterol differed markedly in all age groups in rural and urban circumstances (P < 0.05). Intake of fat and saturated fat was extremely low in all age groups, particularly in the rural subjects. The data suggest that (sub)clinical protein-energy malnutrition is prevelant in Tanzania, and that the high intakes of sucrose and cholesterol and the low intake of fibre by the urban subjects may increase the prevalence of dental caries and cardiovascular diseases in that population.

Diet interviews of subject pairs: how different persons recall eating the same foods.

OBJECTIVE: To compare qualitative descriptions of the same food items eaten by different persons using 24-hour dietary recall interviews. DESIGN: Eleven pairs of subjects were interviewed twice using 24-hour dietary recalls such that each member of the pair described the same day's foods. Each pair shared a home and ate at least 2 meals together daily. After each interview, subjects were asked to identify the foods reported during the interview that they observed the other member of their pair consuming and to note when a particular food was the only item of that type available in the house. Qualitative descriptions of the foods were compared, differences in descriptions were noted, and calculations were made of the potential energy error produced if a subject erred in reporting a food item. SUBJECTS/SETTING: Subjects were randomly selected from a database of persons who have participated in other studies at the Beltsville Human Nutrition Research Center. Ten pairs were husbands and wives and 1 pair was sisters. Each pair reported eating at least 2 meals per day together. Dietary recall interviews were done at the Research Center and were conducted by a trained dietitian in a quiet room free of distractions. RESULTS: Discrepancies in qualitative food descriptions were identified for every subject pair interviewed. Men were found to be more likely to omit food items than women, snack items were more likely to be omitted than meal items, meat items were likely to be described inaccurately, and first interviews were likely to contain more errors than second interviews. APPLICATIONS/CONCLUSIONS: This analysis shows which types of food items are most likely to be omitted or inaccurately described, and that dietetics professionals may improve the accuracy of dietary intake interviews by asking questions related to meat, milk, and snacks very carefully. The analysis also showed reductions in recall inconsistencies from the first recall to the second recall, suggesting that the learning associated with repeated interviews may be helpful in accurately identifying what a person consumes.

Home and eating environments are associated with saturated fat intake in children in rural West Virginia.

OBJECTIVE: To describe sociodemographic, environmental, and knowledge factors in relation to self-reported, energy-adjusted saturated fat consumption among children in rural West Virginia. PARTICIPANTS: Three hundred twenty-five 5th graders who participated in the Coronary Artery Risk Detection in Appalachian Communities Project conducted in 3 rural counties in West Virginia in 1998-1999. METHODS: A cross-sectional survey based on self-reported information collected using a food frequency questionnaire, a nutrition knowledge questionnaire, and a family composition questionnaire. STATISTICAL ANALYSES: Descriptive statistics and multiple linear regression analysis. RESULTS: The mean percentage of energy from total fat was 31.8% +/- 4.9 and from saturated fat was 11.8% +/- 2.3. Energy-adjusted saturated fat intake was significantly higher among children with higher frequencies of breakfast and late-night snacks prepared away from home, and in households with single mothers. Variables associated with higher energy-adjusted saturated fat intake with marginal statistical significance (P=.05-.10) included attendance at schools with a higher percentage of students receiving free or reduced-price lunch, usual breakfast location other than home or school, and less knowledge about low-fat, low-sodium foods. Frequent late-night snacks prepared away from home and living with single mothers remained as significant correlates of energy-adjusted saturated fat intake independent of other hypothesized determinants. CONCLUSION: Efforts to reduce saturated fat intake among children in rural areas should focus on food prepared away from home. Nutrition-related behaviors of single mothers should be explored further.
