“…Most of the predictor concepts and the outcome variable label use were assessed in scales consisting of several items (see Table 1). We based the items of these scales on several previous studies that had examined knowledge, attitudes and beliefs in a health and nutrition context, or numeracy (15,(22)(23)(24)(25)(26)(27)(28) , and completed them with our own questions. Table 1 presents the scales used in the study with one item example each, the internal reliability, mean sum score, number of respondents and original sources*.…”

Objective: Previous studies focused on a limited number of determinants of food label use. We therefore tested a comprehensive model of food label use consisting of sociodemographic, health-related and motivating variables. These three predictor groups were chosen based on the previous literature and completed with new predictors not yet examined in a comprehensive study of frequency of label use. Design: We sent questionnaires to a random sample of households in the Germanspeaking part of Switzerland. Setting: The respondents filled in the questionnaire at home and returned it by mail. Subjects: We analysed the data of 1162 filled-in questionnaires (response rate 5 38 %). Of the respondents, 637 were women (55 %), and their mean age was 53?54 (SD 15?68) years. Results: Health-related variables were the most important group of predictors of label use, followed by motivating factors and sociodemographic variables. Placing importance on health, healthy eating and nutritional value of food, perceived vulnerability for diet-related diseases, nutrition knowledge, numeracy and gender were positively associated with frequency of food label use whereas shopping habits and seeing eating as something positive were negative predictors of frequency of label use. Conclusions: People's health consciousness should be raised in order to increase the frequency of food label use. Furthermore, it should be stressed that reading labels and keeping a healthy diet do not contradict 'good eating', and that both of these aspects can be combined with the help of food labels. Keywords Food label Nutrition table Comprehensive model Predictors of food label useNutrition labels on food products are often praised as an important instrument for health promotion and prevention of diseases associated with overweight and obesity (1)(2)(3)(4) . To find out how this preventive strategy can be used optimally and where the potential starting points for further improvement could be, it is very important to understand what determines use of food labels. This knowledge would help public health communicators to decide to whom and how they need to promote food label use. However, to our knowledge, existing studies investigating food label use have focused mainly on either sociodemographic and economic variables or on health-related factors. No study has systematically included factors inhibiting label use. The aims of the present study were, therefore, to provide a comprehensive framework of determinants of nutrition label use and to shed light on the motivators and inhibitors of nutrition label use. Thereby, we paid attention to three groups of potential determinants of label use: (i) a person's sociodemographic and economic background; (ii) healthrelated aspects; and (iii) factors which discourage people from using food labels (see Fig. 1). We now discuss the relevant factors of each of these three determinants, based on previous studies. One difficulty of studying label use is the number of different labels in the different international marke...

“…Two variables were used to measure parents' NKAN, both based on scales developed and validated by Kristal et al 37 for measuring psychosocial factors related to low-fat diet selection among adult women. The first variable, a summed 23-item scale, assessed parents' knowledge of fats in foods and links among diet and cancer risk, attitudes toward processed foods, and the presence of friends who were switching to healthier eating patterns.…”

Relationships Between Use of Television During Meals and Children's Food Consumption Patterns

et al. 2001

ABSTRACT. Objective. We examined relationships between the presence of television during meals and children's food consumption patterns to test whether children's overall food consumption patterns, including foods not normally advertised, vary systematically with the extent to which television is part of normal mealtime routines.Methods. Ninety-one parent-child pairs from suburbs adjacent to Washington, DC, recruited via advertisements and word of mouth, participated. Children were in the fourth, fifth, or sixth grades. Socioeconomic data and information on television use were collected during survey interviews. Three nonconsecutive 24-hour dietary recalls, conducted with each child, were used to construct nutrient and food intake outcome variables. Independent sample t tests were used to compare mean food and nutrient intakes of children from families in which the television was usually on during 2 or more meals (n ‫؍‬ 41) to those of children from families in which the television was either never on or only on during one meal (n ‫؍‬ 50). Multiple linear regression models, controlling for socioeconomic factors and other covariates, were used to test strength of associations between television and children's consumption of food groups and nutrients.Results. Children from families with high television use derived, on average, 6% more of their total daily energy intake from meats; 5% more from pizza, salty snacks, and soda; and nearly 5% less of their energy intake from fruits, vegetables, and juices than did children from families with low television use. Associations between television and children's consumption of food groups remained statistically significant in multiple linear regression models that controlled for socioeconomic factors and other covariates.Children from high television families derived less of their total energy from carbohydrate and consumed twice as much caffeine as children from low television families. There continued to be a significant association between television and children's consumption of caffeine when these relationships were tested in multiple linear regression models.Conclusion. The dietary patterns of children from families in which television viewing is a normal part of meal routines may include fewer fruits and vegetables and more pizzas, snack foods, and sodas than the dietary patterns of children from families in which television viewing and eating are separate activities.

“…These topics were used by other researchers who determined fibre knowledge (Resnicow & Reinhardt, 1991;Auld et al, 1998). As education stands out as the most important predictor of knowledge scores (Levy et al, 1993), the inclusion of questions on terminology and characteristics was seen as justified because the study group would be higher education students.…”

“…One of the reasons suggested for the inconsistency is that the nutrition knowledge could have been poorly assessed (Kristal et al, 1990;Parmenter & Wardle, 1999). indicate that the use of measures with little consideration of reliability and validity issues has limited the understanding of nutrition knowledge amongst the United Kingdom (UK) public.…”

OPSOMMINGDie doel van hierdie studie was om 'n toets te ontwikkel met dieetvesel as die kennisveld ten einde die geldigheid-en betroubaarheidskwessies rakende voedingkennisbepalings te oorkom. Veertig veelkeusige items is opgestel. Dertien items is tydens die beoordeling van die voorkomsgeldigheid uitgegooi. Dit het die veselterminologie-items ingesluit, sowel as die meeste items wat met veseleienskappe, die funksies van vesel en die dieetaanbevelings verband gehou het. Tien bykomende items is daarna opgestel. Die vraelys het grootliks op voedselbronne wat vesel bevat en praktiese keuses daarvan gefokus en tot 'n mindere mate op siektes wat met veselinname verband hou. Dit is gedoen op aanbeveling van die paneel wat die voorkomsgeldigheid van die items beoordeel het en met ondersteuning uit die literatuur. Al die items is volgens die reëls vir itemkonstruksie opgestel. Die vraelys, wat uit 37 items bestaan het, is deur twee groepe hoëronderwysstudente (n=99 en n=87 onderskeidelik) beantwoord. Die veronderstelling was dat die groepe sou verskil wat voedingkennis betref vanweë hulle ingeskrewe programme. Sewentien vrae is ná die item-analise behou. Ses items het onderskeidelik nie die moeilikheidsindeks en die kriteria vir item-tot-totale-korrelasie geslaag nie, sewe items nie die onderskeidingsindeks-kriteria nie en 13 items nie die veranderlike kriteria nie. Die 17-item-toets is as 'n geldige en betroubare kennismeetinstrument bevestig. 'n Betekenisvolle verskil (p < 0,001) in kennis is in die verwagte rigting tussen die twee groepe studente aangedui deur van die Mann-Whitney-toets gebruik te maak. Die betroubaarheidskoëffisiënt, bepaal deur die Kuder-Richardson-formule 20 (interne konsekwente metode), was 0,9147. Items is volgens hulle moeilikheidsindekse in die toets gerangskik. Die kennistoets kan in 'n groep of individueel gebruik word en die inligting wat ingewin word, kan van waarde wees vir die ontwikkeling van voedingkennistoetse. -Ms Irma Venter
