We tested whether the presence of both child-targeted and nutrition-focused (i.e. parent-targeted) marketing cues on food packaging was associated with the nutritional content of these products.
Design
We conducted a quantitative content analysis of 403 food packages chosen randomly from the supermarket’s online portal along with all products (n 312) from the cereal aisle in a supermarket from the Southeastern USA. We examined main and interaction effects for cues on nutritional content (e.g. energy density, sugar, sodium, fibre).
Setting
A regional supermarket chain in the Southeastern USA.
Results
Tests of main effects indicated that increased presence of nutritional cues was linked to more nutritious content (e.g. less sugar, less saturated fat, more fibre) while the increased presence of child-targeted cues was uniformly associated with less nutritious content (e.g. more sugar, less protein, less fibre). Among the interaction effects, results revealed that products with increased nutrition-focused and child-targeted cues were likely to contain significantly more sugar and less protein than other products.
Conclusions
Products that seek to engage children with their packaging in the supermarket are significantly less nutritious than foods that do not, while product packages that suggest nutritional benefits have more nutritious content. More importantly, the study provides evidence that those products which try to engage both child and parent consumers are significantly less healthy in crucial ways (e.g. more sugar, less fibre) than products that do not.
The present study investigated whether parent/child pairs would select more healthful foods when: (i) products were labelled with front-of-package (FOP) nutrition labels relative to packages without labels; (ii) products were labelled with colour-coded Multiple Traffic Light (MTL) FOP labels relative to monochromatic Facts up Front (FuF) FOP labels; and (iii) FOP labels were explained via in-aisle signage v. unexplained.
Design
Participants were randomly assigned to one of five conditions: (i) FuF labels with in-aisle signs explaining the labels; (ii) FuF labels, no signage; (iii) MTL labels with in-aisle signage; (iv) MTL labels, no signage; (v) control group, no labels/signage. Saturated fat, sodium, sugar and energy (calorie) content were compared across conditions.
Setting
The study took place in a laboratory grocery aisle.
Subjects
Parent/child pairs (n 153) completed the study.
Results
Results did not support the hypothesis that MTL labels would lead to more healthful choices than FuF labels. The presence of FOP labels did little to improve the healthfulness of selected foods, with few exceptions (participants with v. without access to FOP labels selected lower-calorie cereals, participants with access to both FOP labels and in-aisle explanatory signage selected products with less saturated fat v. participants without explanatory signage).
Conclusions
Neither MTL nor FuF FOP labels led to food choices with significantly lower saturated fat, sodium or sugar. In-aisle signs explaining the FOP labels were somewhat helpful to consumers in making more healthful dietary decisions. New FOP labelling programmes could benefit from campaigns to increase consumer awareness and understanding of the labels.
The ability to use serving size information on food labels is important for managing age-related chronic conditions such as diabetes, obesity and cancer. Past research suggests that older adults are at risk for failing to accurately use this portion of the food label due to numeracy skills. However, the extent to which older adults pay attention to serving size information on packages is unclear. We compared the effects of numeracy and attention on age differences in accurate use of serving size information while individuals evaluated product healthfulness.
Design
Accuracy and attention were assessed across two tasks in which participants compared nutrition labels of two products to determine which was more healthful if they were to consume the entire package. Participants’ eye movements were monitored as a measure of attention while they compared two products presented side-by-side on a computer screen. Numeracy as well as food label habits and nutrition knowledge were assessed using questionnaires.
Setting
Sacramento area, California, USA, 2013–2014.
Subjects
Stratified sample of 358 adults, aged 20–78 years.
Results
Accuracy declined with age among those older adults who paid less attention to serving size information. Although numeracy, nutrition knowledge and self-reported food label use supported accuracy, these factors did not influence age differences in accuracy.
Conclusions
The data suggest that older adults are less accurate than younger adults in their use of serving size information. Age differences appear to be more related to lack of attention to serving size information than to numeracy skills.
According to the US Affordable Care Act, restaurant chains are required to provide energy (calorie) and other nutrition information on their menu. The current study examined the impact of menu labelling containing calorie information and recommended daily calorie intake, along with subjective nutrition knowledge, on intention to select lower-calorie foods prior to the implementation of the Affordable Care Act.
Design
Full factorial experimental design with participants exposed to four variants of a sample menu in a 2 (presence v. absence of calorie information) ×2 (presence v. absence of recommended daily calorie intake).
Setting
Large, public university in the Southwest USA.
Subjects
Primarily undergraduate college students.
Results
Majority of participants were 19–23 years of age (mean 21·8 (sd 3·6) years). Menu information about calorie content and respondents’ subjective nutrition knowledge had a significantly positive impact on students’ intention to select lower-calorie foods (β=0·24, P<0·001 and β=0·33, P<0·001, respectively); however, recommended daily calorie intake information on the menu board did not influence students’ intention to select lower-calorie foods (β=0·10, P=0·105). Gender played a significant role on purchase intent for lower-calorie menu items, with females more affected by the calorie information than males (β=0·37, P<0·001).
Conclusions
Findings support the role menu labelling can play in encouraging a healthier lifestyle for college students. College students who are Generation Y desire healthier menu options and accept nutritional labels on restaurant menus as a way to easily and expediently obtain nutrition information.
To analyse patterns of knowledge, comprehension, attitudes and practices regarding the traffic light label placed on processed food packages to inform Ecuadorian consumers about levels of added fat, sugar and salt.
Design
Twenty-one focus group discussions organized by age group, sex and place of residence. Interviews with representatives of companies that manufacture or market processed foods. Analysis of regulations and structured observations of processed food labels.
Setting
Cities and towns in Ecuador’s coastal, highland and eastern lowland regions.
Subjects
One hundred and seventy-eight participants in twenty-one focus group discussions and nine key informants.
Results
Focus group participants knew about the traffic light label and understood the information it conveys, but not all changed their attitudes and practices related to the purchase and consumption of processed foods. Children, adolescents and adult males reported using the information infrequently; adolescents interested in health and adult women used the label the most to select products. Representatives of companies that manufacture or market processed foods generally opposed the policy, stating that the information is misleading. Nevertheless, some companies have reduced levels of added fat, sugar or salt in their products.
Conclusions
The traffic light label is an effective tool for conveying complex information. Its potential contribution to reduce consumption of products with high levels of fat, sugar and salt could be enhanced by promoting healthy diets among consumers who have not changed purchasing and consumption behaviour, by placing the label on front panels and by monitoring the production and marketing of processed foods.
We conducted a content analysis of public comments to understand the key framing approaches used by private industry v. public health sector, with the goal of informing future public health messaging, framing and advocacy in the context of policy making.
Design
Comments to the proposed menu-labelling policy were extracted from Regulations.gov and analysed. A framing matrix was used to organize and code key devices and themes. Documents were analysed using content analysis with Dedoose software.
Setting
Recent national nutrition-labelling regulations in the USA provide a timely opportunity to understand message framing in relation to obesity prevention and policy.
Subjects
We examined a total of ninety-seven documents submitted on behalf of organizations (private industry, n 64; public health, n 33).
Results
Public health focused on positive health consequences of the policy, used a social justice frame and supported its arguments with academic data. Industry was more critical of the policy; it used a market justice frame that emphasized minimal regulation, depicted its members as small, family-run businesses, and illustrated points with humanizing examples.
Conclusions
Public health framing should counter and consider engaging directly with non-health-related arguments made by industry. Public health should include more powerful framing devices to convey their messages, including metaphors and humanizing examples.
To determine the effects of increasing plant-based foods v. dairy foods on energy and nutrients of concern in adolescent females via diet modelling exercises.
Design
Data from the National Health and Nutrition Examination Survey (NHANES) were used to compare nutrient intakes from usual diet with those from three dietary scenarios that increased current intakes by 100 % of the following: (i) plant-based foods; (ii) protein-rich plant-based foods; and (iii) milk, cheese and yoghurt. The first two scenarios had commensurate reductions in animal products.
Setting
What We Eat in America, NHANES 2007–2010.
Subjects
Female adolescents (n 1594) aged 9–18 years.
Results
When currently consumed plant-based foods were increased by 100 %, there were increases in dietary fibre, added sugar, vitamin E, Fe and folate intakes. These increases were accompanied by decreases in total fat, saturated fat, Zn, vitamin D, Ca and protein intakes. Protein-rich plant foods are consumed in very low quantities in this population such that doubling their intake resulted in no real nutritional impact. When dairy products were increased by 100 % there were increases in intakes of vitamin D, Mg, Zn, Ca, K, energy, saturated fat and protein.
Conclusions
Non-specific recommendations to increase plant foods can lead to unintended nutritional consequences. For adolescent girls, meeting the dietary recommendation of three daily servings of dairy improved the intake of the identified nutrients of concern while simultaneously providing adequate nutrients essential for proper growth and bone health critical during the adolescent phase.
To identify barriers to fruit and vegetable intake for Indigenous Australian children and quantify factors related to these barriers, to help understand why children do not meet recommendations for fruit and vegetable intake.
Design
We examined factors related to carer-reported barriers using multilevel Poisson models (robust variance); a key informant focus group guided our interpretation of findings.
Setting
Eleven diverse sites across Australia.
Subjects
Australian Indigenous children and their carers (N 1230) participating in the Longitudinal Study of Indigenous Children.
Results
Almost half (45 %; n 555/1230) of carers reported barriers to their children’s fruit and vegetable intake. Dislike of fruit and vegetables was the most common barrier, reported by 32·9 % of carers; however, we identified few factors associated with dislike. Carers were more than ten times less likely to report barriers to accessing fruit and vegetables if they lived large cities v. very remote areas. Within urban and inner regional areas, child and carer well-being, financial security, suitable housing and community cohesion promoted access to fruit and vegetables.
Conclusions
In this national Indigenous Australian sample, almost half of carers faced barriers to providing their children with a healthy diet. Both remote/outer regional carers and disadvantaged urban/inner regional carers faced problems accessing fruit and vegetables for their children. Where vegetables were accessible, children’s dislike was a substantial barrier. Nutrition promotion must address the broader family, community, environmental and cultural contexts that impact nutrition, and should draw on the strengths of Indigenous families and communities.
Parental feeding practices shape children’s relationships with food and eating. Feeding is embedded socioculturally in values and attitudes related to food and parenting. However, few studies have examined associations between parental feeding practices and migrant background.
Design
Cross-sectional study. Parental feeding practices (restriction, pressure to eat, monitoring) were assessed using the Child Feeding Questionnaire. Differences were explored in four sub-samples grouped by maternal place of birth: Sweden, Nordic/Western Europe, Eastern/Southern Europe and countries outside Europe. Crude, partly and fully adjusted linear regression models were created. Potential confounding variables included child’s age, gender and weight status, and mother’s age, weight status, education and concern about child weight.
Setting
Malmö and Stockholm, Sweden.
Subjects
Mothers (n 1325, representing seventy-three countries; mean age 36·5 years; 28·1 % of non-Swedish background; 30·7 % with overweight/obesity; 62·8 % with university education) of pre-school children (mean age 4·8 years; 50·8 % boys; 18·6 % with overweight/obesity).
Results
Non-Swedish-born mothers, whether European-born or non-European-born, were more likely to use restriction. Swedish-born mothers and Nordic/Western European-born mothers reported lower levels of pressure to eat compared with mothers born in Eastern/Southern Europe and mothers born outside Europe. Differences in monitoring were small. Among the potential confounding variables, child weight status and concern about child weight were highly influential. Concern about child weight accounted for some of the effect of maternal origin on restriction.
Conclusions
Non-European-born mothers were more concerned about children being overweight and more likely to report controlling feeding practices. Future research should examine acculturative and structural factors underlying differences in feeding.
In 2011, Dietitians of Canada added ‘My Goals’ to its website-based nutrition/activity tracking program (eaTracker®, http://www.eaTracker.ca/); this feature allows users to choose ‘ready-made’ or ‘write-your-own’ goals and to self-report progress. The purpose of the present study was to document experiences and perceptions of goal setting and My Goals, and report users’ feedback on what is needed in future website-based goal setting/tracking tools.
Design
One-on-one semi-structured interviews were conducted with (i) My Goals users and (ii) dietitians providing a public information support service, EatRight Ontario (ERO).
Setting
My Goals users from Ontario and Alberta, Canada were recruited via an eaTracker website pop-up box; ERO dietitians working in Ontario, Canada were recruited via ERO.
Subjects
My Goals users (n 23; age 19–70 years; 91 % female; n 5 from Alberta/n 18 from Ontario) and ERO dietitians (n 5).
Results
Dietitians and users felt goal setting for nutrition (and activity) behaviour change was both a beneficial and a challenging process. Dietitians were concerned about users setting poor-quality goals and users felt it was difficult to stick to their goals. Both users and dietitians were enthusiastic about the My Goals concept, but felt the current feature had limitations that affected use. Dietitians and users provided suggestions to improve My Goals (e.g. more prominent presence of My Goals in eaTracker; assistance with goal setting; automated personalized feedback).
Conclusions
Dietitians and users shared similar perspectives on the My Goals feature and both felt goal use was challenging. Several suggestions were provided to enhance My Goals that are relevant to website-based goal setting/tracking tool design in general.
The present research aimed to study the multidimensionality of the link between dietary intake and socio-economic position (SEP) in a representative sample of French children and adolescents, using a variety of SEP indicators.
Design
Data from the second French national food consumption survey (INCA2) were used. Information on food consumption was collected using a 7d food record and SEP data (occupation, education, income, household wealth indices) using questionnaires. Multivariable linear regression analyses were performed separately in children and adolescents to assess the relationships between dietary components (food groups and macronutrients) and each dimension of SEP.
Setting
The INCA2 survey, France.
Subjects
A representative sample of French children (3–10 years of age; n 574) and adolescents (11–17 years of age; n 881).
Results
Compared with children from a higher SEP, those from a lower SEP had lower intakes of fruit and vegetables, yoghurts and confectionery and higher intakes of starchy foods, meat, milk, sugar-sweetened beverages and pizzas/sandwiches. Similar results were observed in adolescents for fruit and vegetables, yoghurts and sugar-sweetened beverages. Adolescents also had lower intakes of cakes/pastries and higher intakes of processed meat and dairy desserts. Neither energy nor protein intake was associated with SEP. Adolescents from a lower SEP had higher carbohydrate and lower lipid intakes. Overall, these findings were consistent across the various dimensions of SEP, but the gradient was steeper depending on the caregiver’s educational level.
Conclusions
This research highlights the need for specific messages to help poorly educated families adopt good eating habits.
To investigate demographic and lifestyle factors associated with adherence to the Mediterranean diet (MD) in Israeli adolescents.
Design
Cross-sectional.
Setting
School-based.
Subjects
Schoolchildren (n 5268) aged 11–19 years answered self-administered questionnaires on food consumption, eating habits and lifestyle; a subset (n 578) also completed 24 h food recalls.
Results
Using a modified KIDMED index, 25·5 % of the students had poor, 55·2 % had average and 19·3 % had good MD adherence. Jewish middle-school children had the highest proportion (28·2 %) of poor MD adherence. Olive oil usage, derived from 24 h food recalls, was 18·1 % in Jewish families v. 71·1 % in Arab homes. In Jewish boys, the odds (OR; 95 % CI) of having poor MD adherence was higher in those who watched television/videos/listened to music for ≥2 h/d (1·25; 0·98, 1·58) and those who sometimes/don’t read food labels (1·69; 1·31, 2·18). In Jewish girls, the odds for having poor MD adherence was significantly higher in those whose mother’s schooling was <12 years (2·06; 1·41, 3·00) and those who sometimes/don’t read food labels (1·35; 1·08, 1·69). In Arab boys, watching television/videos/listening to music for ≥2 h/d was significantly associated with poor MD adherence (1·89; 1·16, 3·07). In Arab girls, no aerobic activity or ball games weekly was associated with poor MD adherence (1·38; 0·91, 2·09).
Conclusions
Israeli adolescents had overall a high rate of poor MD adherence. Jewish middle-school children were at the highest risk. Interventions aimed at increasing physical activity, reducing sedentary time, improving mother’s education and promoting reading of food labels are recommended.
To examine the relationship between dietary energy density (DED) and risk of metabolic syndrome (MetS), its components and inflammatory markers.
Design
Cross-sectional study. Dietary intakes were assessed using a validated dish-based semi-quantitative FFQ. DED was calculated by dividing energy intake (kcal/d) by the total weight of foods only (g/d). MetS was defined based on the National Cholesterol Education Program Adult Treatment Panel III criteria. All associations were examined in the quartiles of DED, with higher quartiles indicating more energy-dense diets.
Setting
Isfahan, Iran.
Subjects
Female nurses (n 1036) aged >30 years.
Results
After controlling for potential confounders, individuals in the top quartile of DED had 78 % greater chance of MetS compared with those in the first (OR=1·78; 95 % CI 1·36, 2·98; P<0·001). Individuals in the highest quartile of DED were more likely to be abdominally obese (OR=1·51; 95 % CI 1·00, 2·63) and have hypertriacylglycerolaemia (OR=2·95; 95 % CI 1·58, 3·91) and low HDL cholesterol levels (OR=1·36; 95 % CI 1·17, 2·54) compared with those in the lowest quartile. Mean concentration of plasma high-sensitivity C-reactive protein (hs-CRP) across increasing quartiles of DED was 1·7, 1·7, 2·0, 2·4 mg/l (P for trend=0·04). Such increasing concentrations across increasing quartiles of DED were also seen for TNF-α (4·1, 4·5, 4·5, 4·8 ng/l; P for trend=0·03) and IL-6 (1·6, 1·6, 1·5, 2·5 ng/l; P for trend <0·01).
Conclusions
Consumption of high-energy-dense foods was associated with increased chance of MetS, most of its features and inflammatory markers including hs-CRP, TNF-α and IL-6.
The present review aimed to identify and synthesize literature on household food insecurity with respect to whether the respondent was male or female.
Design
A systematic review of prevalence studies followed by a meta-analysis was conducted between 28 August 2014 and 19 October 2014 in seven electronic databases. The search was updated in April 2016. The included studies used experience-based measures to assess household food insecurity. Dichotomous measures of food insecurity were used. Pooled odds ratios of household food insecurity prevalence in women v. men were obtained through random-effect modelling. Quality assessment, publication bias diagnostics and subgroup analysis were also performed.
Out of the 5145 articles initially identified, forty-two studies with a total population of 233 153 were included. In general, results showed that the odds for household food insecurity was 40 % higher in studies where women were the respondent (95 % CI 1·27, 1·54; P<0·001). Besides, subgroup analysis revealed that female-headed households were 75% (95 % CI 49–96%) more likely to be food insecure than male-headed households.
Conclusions
Our results confirm the existence of gender differences in reporting household food insecurity. Furthermore, they indicate that households headed by women constitute a segment of the population that is particularly vulnerable to food insecurity.
To explore how an Australian rural food policy coalition acts to influence a local food environment, focusing specifically on its composition, functions and processes as well as its food-related strategies and policy outputs.
Design
A qualitative case study approach was undertaken. Three sources were used to triangulate data: eleven semi-structured in-depth interviews with coalition members, analysis of thirty-seven documents relating to the coalition and observation at one coalition meeting. Data were analysed using a thematic and constant comparison approach. Community Coalition Action Theory provided a theoretical framework from which to interpret findings.
Setting
Two rural local government areas on the south-eastern coast of Victoria, Australia.
Subjects
Eleven members of the food policy coalition.
Results
Five themes emerged from the data analysis. The themes described the coalition’s leadership processes, membership structure, function to pool resources for food system advocacy, focus on collaborative cross-jurisdictional strategies and ability to influence policy change.
Conclusions
This Australian case study demonstrates that with strong leadership, a small-sized core membership and focus on collaborative strategies, food policy coalitions may be a mechanism to positively influence local food environments.
We investigated the association between junk food consumption at lunchtime (JCL) and fast-food outlet access near school among secondary-school children in Quebec.
Design
A geographic information system database was used to characterize the food environment around a sub-sample of 374 public schools in which 26 655 students were enrolled. The outcome variable was JCL during the previous week, dichotomized into low JCL (none or once) v. high JCL (twice or more). Access to fast-food outlets near school was assessed using an existing database of fast-food outlets in Quebec. Covariates included student (age, sex and self-rated perceived health), family (familial status and parental education) and school (urban/rural status and deprivation) variables. Hierarchical logistic regression models were employed for analyses using PROC GLIMMIX of SAS version 9.3.
Setting
Province of Quebec, Canada.
Subjects
We used data from the Quebec Health Survey of High School Students (QHSHSS) 2010–11, a survey of secondary-school Quebec students.
Results
Exposure to two or more fast-food outlets within a radius of 750 m around schools was associated with a higher likelihood of excess JCL (OR=1·50; 95 % CI 1·28, 1·75), controlling for the characteristics of the students, their families and their schools.
Conclusions
The food environment surrounding schools can constitute a target for interventions to improve food choices among secondary-school children living in the province of Quebec. Transforming environments around schools to promote healthy eating includes modifying zoning regulations that restrict access to fast-food outlets around schools.
The traditional Mediterranean diet includes high consumption of fruits, vegetables, olive oil, legumes, cereals and nuts, moderate to high intake of fish and dairy products, and low consumption of meat products. Intervention effects to improve adoption of this diet may vary in terms of individuals’ motivational or volitional prerequisites. In the context of a three-country research collaboration, intervention effects on these psychological constructs for increasing adoption of the Mediterranean diet were examined.
Design
An intervention was conducted to improve Mediterranean diet consumption with a two-month follow-up. Linear multiple-level models examined which psychological constructs (outcome expectancies, planning, action control and stage of change) were associated with changes in diet scores.
Setting
Web-based intervention in Italy, Spain and Greece.
Subjects
Adults (n 454; mean age 42·2 (sd 10·4) years, range 18–65 years; n 112 at follow-up).
Results
Analyses yielded an overall increase in the Mediterranean diet scores. Moreover, there were interactions between time and all four psychological constructs on these changes. Participants with lower levels of baseline outcome expectancies, planning, action control and stage of change were found to show steeper slopes, thus greater behavioural adoption, than those who started out with higher levels.
Conclusions
The intervention produced overall improvements in Mediterranean diet consumption, with outcome expectancies, planning, action control and stage of change operating as moderators, indicating that those with lower motivational or volitional prerequisites gained more from the online intervention. Individual differences in participants’ readiness for change need to be taken into account to gauge who would benefit most from the given treatment.
