The role of dietary information in women's whole milk and low‐fat milk intakes

This study examines the effects of dietary information on women's whole and low‐fat milk intakes. The sample is 1928 female meal planners aged 20 years or over who provided information on their milk intake for 2 days in the 1994–96 Continuing Survey of Food Intakes by Individuals and who completed the 1994–96 Diet and Health Knowledge Survey in the follow‐up interview. The nested Tobit model was used to handle the sequentially censored data. Women's dietary information contributed to reduced whole milk consumption and increased low‐fat milk consumption indicating different effects on whole milk and low‐fat milk consumption.     

Chinese dietary culture influences consumers' intention to use imported soy‐based dietary supplements: an application of the theory of planned behaviour

The over‐saturated dietary supplement (DS) market in developed countries such as the US spurs the need for foreign market expansion, and the Chinese market provides a great potential for the foreign soy‐based DS industry. This study examined Chinese consumers' intention to use imported (US‐made US‐brand) soy‐based DS based on the Theory of Planned Behavior (TPB). Two alternative models were also examined in which Chinese dietary culture variables, including soyfoods favourability and dining‐out sociability, as well as their interactions with attitudes, were integrated into the TPB model. A cross‐sectional, self‐administered survey was conducted with a sample of 215 subjects (137 females; 78 males) in Shanghai, China. The TPB variables attitude, subjective norm, perceived behaviour control and behavioural intention, as well as the Chinese dietary culture variables: soyfoods favourability and dine‐out sociability were measured. Multiple linear regressions were used to analyze the three models. The statistical results indicated that all three models were statistically significant to predict intention (Model 1: R² = 0.473, P < 0.001; Model 2: R² = 0.505, P < 0.001; Model 3: R² = 0.525, P < 0.001). The results also showed that attitude, perceived behavioural control, and dine‐out sociability were significant (positive) determinants of intention. Soyfoods favourability acted a significant (negative) moderator of the relationship between attitude and intention. Subjective norm had no significant impact on intention. In conclusion, the TPB model was useful to predict Chinese consumers' intention to use imported soy‐based DS, but not all the TPB components weighed significantly in exploring DS consumption in China. The selected Chinese dietary culture variables were much more important predictors than subjective norm. This study makes a significant contribution in the application of the TPB model and in market strategy development for imported dietary supplements in China.     

Food consumption patterns,dietary quality and health status of expectant mothers: case studies in suburban and rural communities in Ghana

The study was conducted to determine the food consumption patterns, dietary quality and health status of expectant women and also to assess their level of awareness of nutritional requirements during pregnancy. Food beliefs, taboos and superstitions held by the women were also investigated. Using the purposive sampling technique, 30 pregnant women attending the Maternal and Child Health Clinic at Dodowa (rural) and University Hospital, Legon (suburban), were selected for the study. A structured questionnaire was used to collect information on the respondents’ nutritional knowledge, beliefs, taboos and superstitions and health status. A food frequency questionnaire and the 24‐h dietary recall method were used to obtain information on food consumption patterns and dietary quality. The study revealed that, although the majority of the respondents (83.3%) had some knowledge of nutrition, not all were applying it in their feeding practices because of financial constraints. With regard to consumption patterns, most of the women (83.3%) were having three meals a day, while the rest either ate twice a day or anytime they were hungry. Seventy‐three per cent of the respondents also increased their food intake during pregnancy. Foods eaten were based mainly on starchy roots and tubers, cereals and vegetables. Legumes, oilseeds and fruits were often lacking in the main meals of respondents. Although animal products were consumed daily, the quantities taken were very small to provide for adequate protein, especially in the rural area. Various types of food were avoided by some of the expectant mothers for reasons such as nausea, loss of appetite, taboos and superstition. With regard to dietary quality, respondents from the rural area had diets of poorer quality in terms of nutrient intake compared with those from the suburban area. In both communities, iron contents of diets were quite low. Forty‐seven per cent of the women interviewed were anaemic, with a higher prevalence of anaemia being observed in the rural community. Common ailments reported by the women were dizziness, headache, waist pains and malaria. Based on the results of the study, it was recommended that nutrition education for pregnant women should be stepped up at antenatal clinics especially in rural areas.     

Satisfaction of disabled rural elders and adults with the quality of community‐based long‐term care services

This study estimates the probability of being satisfied with community‐based health care services in a rural area and compares the formation of satisfaction for elders and younger disabled adults. Using data from a state in New England, USA, a multivariate binomial logit model was used to estimate the probability of being satisfied. The formation of satisfaction differs for rural disabled adults and elders. Two out of five need characteristics were found to influence satisfaction with quality of care, and four out of six enabling characteristics were found to influence satisfaction. The impact of these characteristics differs for disabled elders and adults, pointing to the need to differentiate the disabled population when developing systems of home‐based care.     

The effects of the US Food Stamp Program on the dietary quality of parents and their teenagers and children1

Although previous research finds that participation in Food Stamp Programs increases the nutrient availability of low‐income households, examination of the dietary quality of parents, their teenagers (aged 13–18 years), and their children (aged 1–12 years) indicates that participation has no effect on dietary quality of any of these groups. Examination of data from the Continuing Survey of Food Intake by Individuals and Diet and Health Surveys, conducted in the USA, 1994–96, indicates that although transfer payments in the Food Stamp Program might improve quality of life in other areas by freeing income otherwise spent on food, the receipt of food assistance does not improve dietary quality. The findings show that children tend to eat healthier diets than their parents or teenage siblings. Implications are suggested regarding the use of transfer payments to improve the dietary quality of persons living in poverty.     

Child–mother nutrition and health status in rural Kenya: the role of intra‐household resource allocation and education

There exists gender bias in resource ownership in many parts of Kenya with women being more disadvantaged. Resource ownership and control within the household has differential impacts on the health and overall well‐being of male and female members. This paper examines intra‐household resource ownership and how it affects nutrition and health status of household members. Data from a household survey containing detailed gender‐disaggregated information on resource ownership as well as food and anthropometry were collected from a rural Kenyan district and used in the analysis. Results showed that male members of the household had more access to education, income and land than the females. Mothers’ education, household income, frequency of illness and nutrient intake were the most important factors that contributed to the nutritional status of children. The education and household’s economic status were important determinants of child morbidity. Malnutrition and poor health of children and women is linked to the existing poverty in the study region, therefore emphasis needs to be put on eradication of discrimination against women in accessing education and accessing land, which will contribute to an increase in household incomes. Government policies need to focus on promotion of nutrition education through adult education programmes and incorporating it in the school curricula. Improvement of health‐care facilities in rural areas is also paramount to improving health and nutrition in these areas.     

The effectiveness of deservingness‐based advertising messages: The role of product knowledge and belief in a just world

Are advertisements that tell consumers they deserve a product effective? Given evidence showing people are motivated to get what they deserve, we argue that for certain consumers this is the case. In two experiments, we manipulated the type of ad participants viewed for a luxury product and then assessed ad effectiveness. We also measured participants’ belief in a just world (BJW) and product knowledge. Deservingness‐based ads were (a) more effective for strong BJW participants, mediated by the degree to which the ads matched participants’ worldview and justified buying the product, and (b) less effective for high knowledge participants. We conclude that deservingness‐based advertising can be successful, depending on consumer characteristics. Copyright © 2016 ASAC. Published by John Wiley & Sons, Ltd.     

The attitudes and nutritional knowledge of 11‐ to 12‐year‐olds in Merseyside and Northern Ireland

School is a major area for providing young people with nutritional knowledge and skills. In Northern Ireland home economics (HE) is taught to 11‐ to 12‐year‐olds. The 1988 Education Reform Act introduced the national curriculum and HE as a subject was effectively abolished in English schools, and key stage 3 pupils in England are taught nutrition in Science, Design and Technology and in the cross curricular theme of health education. The aim of the study was to compare the attitudes and nutritional knowledge of children in Merseyside, England (M) and Northern Ireland (NI). A questionnaire was designed, which examined attitudes to aspects of healthy eating and tested the subject's knowledge, practical and theoretical, on nutrition and healthy eating. Subjects aged 11–12 years were recruited (M: 541, NI: 128). The majority ‘understood and knew what to eat to have a healthy diet’, ‘liked the taste of healthy food’ and considered that ‘there were healthy foods at home’. However, a significantly greater number in Merseyside agreed that ‘their health will be affected in the future by what they eat now’ (M: 71%, NI: 54%, P < 0.01) and agreed that ‘they enjoyed cooking’ (M: 76%, NI: 56%, P < 0.01). Whereas more from Northern Ireland agreed that ‘they do not know what foods to eat to have a healthy diet’ (M: 14%, NI: 30%, P < 0.01), ‘that healthy eating involved “dieting” ’ (M: 29%, NI: 59%, P < 0.01) and agreed that ‘there are no healthy food choices at school’ (M: 23% NI: 42%, P < 0.01). More subjects from Merseyside disagreed that ‘healthy eating is a waste of time’ (M: 87%, NI: 77%, P < 0.01). The mean knowledge scores (correct answers) from Merseyside were significantly greater than from Northern Ireland (total score: M: 51%, NI: 43%P < 0.05; practical score: M: 58%, NI: 49%P < 0.05, theory score: M: 38%, NI: 31%, P < 0.05). The results indicate that the healthy food message seems to have been better learnt by children in Merseyside but results of surveys in Merseyside into eating habits suggest that many have not put this knowledge into practice.     

A two‐sector neo‐Kaleckian model of growth and distribution: Investment allocation and evolutionary dynamics

This paper focuses on the two‐sector neo‐Kaleckian model of growth and distribution that was developed by Dutt (1990) and challenged by Park (1995). We develop a variant of this model, focusing on the supply‐side to solve the overdetermination problem that was raised by Park. Finally, we introduce evolutionary dynamics to model the investment flows between the capital and consumer goods sectors. In this setup, the sectoral profit rates and the size of capital stocks wield an essential role upon the entrepreneur’s decision on which sector to invest in. This model is perfectly determined and it generates a stable evolutionary equilibrium over the long term.     

Relationship between types of food choice motives and well‐being among young and middle‐aged Chinese adults

Food choice plays a vital role in people’s lives and well‐being, and this topic has received more research attention in recent years. The aims of the present research were to identify subgroups of participants who shared similar profiles of multiple motives for food choices, and examine differences across motive types on the well‐being of young and middle‐aged Chinese adults. Participants were 627 Chinese adults aged 18–58 years who completed questionnaire measures. The results of Latent Profile Analysis showed that based on the configurations among different motives for food choice, there were five profiles of food choice motives, corresponding to five types of Chinese adult consumers: unconcerned, mood oriented, weight control oriented, food enthusiast and health oriented. The food enthusiast consumers were more likely to include young adults with high‐income level and educational level, while the unconcerned consumers had a larger share of middle‐aged adults with low income. Results of ANOVA suggested that the types of food choice motives significantly predicted individuals’ well‐being. Specifically, the food enthusiast group had the highest level of well‐being, while the unconcerned group had the lowest level of well‐being. The other three groups had moderate levels of well‐being. The current study is the first to explore the potential influence of food choice motives on well‐being using a person‐centred approach, and the results have practical implications for public health authorities in developing effective interventions, for food companies in tailoring marketing campaigns and for individuals in optimizing food choices.     

Adolescents' body‐tanning behaviours: influences of gender,body mass index,sociocultural attitudes towards appearance and body satisfaction

The goal of this study was to identify and examine the various factors affecting adolescents' body‐tanning behaviours. Gender, body mass index (BMI), sociocultural attitudes towards appearance (SATA) and body satisfaction were examined in order to determine how these variables influence both outdoor sun‐tanning and indoor tanning‐bed use. Self‐administered survey data were collected from 155 adolescent boys and 202 adolescent girls with an average age of 14.3. Multivariate analysis of variance and multiple regression methods were used to analyse the data. Adolescent girls tended to engage in both outdoor and indoor tanning. Overall, adolescents' SATA significantly affected their body‐tanning behaviours. However, BMI and body satisfaction revealed a significant effect only on indoor tanning behaviour. Implications for the design of interventions and overall health promotion towards adolescents are discussed with suggestions for future research.     

The Non‐Observed Economy in Portugal: The monetary model and the MIMIC model

This paper offers estimations for the Portuguese path of the Non‐Observed Economy (NOE), in the period 1970–2015, through two seminal approaches: monetary method and the Multiple Indicators Multiple Causes (MIMIC) model. It is observed that the tax burden and social benefits are its main causes. Then, to get a more in‐depth understanding of the phenomenon, it provides a study of the Granger causality between the NOE and the official Gross Domestic Product (GDP), emphasizing the implications of the NOE on the Portuguese economy. Evidence has been found for the existence of bidirectional causality between the NOE and the GDP, suggesting that the formal economy affects the NOE, and conversely that the NOE affects the economic growth.     

Pilot intervention with adolescents to increase knowledge and consumption of folate‐rich foods based on the Health Belief Model

Folate is important in the prevention of birth defects and in the maintenance of general health. Even after mandatory fortification, many people are still not consuming the recommended dietary allowance (RDA) of 400 mcg folate/day. Consuming a diet rich in naturally high‐folate foods, as opposed to supplementation, may offer additional health benefits and promote an overall healthy diet. The purpose of this pilot study was to test the hypothesis that a learner‐centred educational intervention based on the Health Belief Model (HBM) will successfully increase knowledge and consumption of folate‐rich foods, while increasing positive beliefs about folate and health in adolescents. A two‐group parallel control trial was conducted in two schools in Nebraska. Pre‐ and post‐study questionnaires included a folate‐based food frequency questionnaire, a HBM questionnaire and a folate knowledge test. Participants in the intervention group completed a post‐study evaluation. The intervention consisted of three 30‐min lessons followed by participant creation of podcasts. One podcast was viewed each week for 8 weeks following the lessons. Data were analysed using t‐tests to measure simple effects within the intervention and control groups, and analysis of variance to measure within‐subject effects between the groups. Folate consumption decreased in both the intervention and control groups, but these differences were not significant (P > 0.05). Significant increases (P = 0.000) in folate knowledge occurred in the intervention group. This difference remained significant (P = 0.001) when compared to the control group. Average HBM rankings significantly decreased (P < 0.05) towards ‘strongly agree’ (Likert scale of 1–6) in the intervention group (P < 0.05) for all constructs except cues to action. However, when compared to the control group, these differences were only significant for self‐efficacy and perceived susceptibility. Creating and viewing podcasts may be helpful for the retention of knowledge over time, but did not appear to be an effective cue to action for increased folate‐rich foods in this pilot study.     

Exploring the nutrition and lifestyle knowledge,attitudes and behaviour of student home economics teachers: baseline findings from a 4‐year longitudinal study

It is widely acknowledged that obesity linked with reduced exercise contributes to health problems, and that, conversely, individuals who embark on weight reducing diets may become deficient in key nutrients. It is often advocated that these problems, which can be grouped together as poor dietary practice, be tackled through education. This study attempts to examine the relationship between nutrition education and lifestyle behaviours in a select group of third level students. The Irish Home Economics curriculum aims to teach secondary school pupils about nutrition and lifestyle practices conducive to health. However, the attitudes and lifestyle practices of those teaching this subject have never been examined in Ireland. The purpose of the present 4‐year longitudinal study, whose first year findings are presented here, is to investigate the nutrition and lifestyle knowledge, attitudes and behaviours of a cohort of Irish student home economics teachers over the 4 years of their Bachelor of Education (Home Economics) degree course. The study was designed to explore possible changes in knowledge, attitudes and practices over the course of their professional education. Nutritional knowledge was measured using a 220‐question adapted version of the test devised by Parmenter and Wardle. Attitudes were measured using a questionnaire adapted from the Pan‐EU Survey on Consumer Attitudes to Physical Activity, Body‐weight and Health. Food, alcohol consumption and exercise were measured using a 7‐day reported dietary/exercise diary. Nutrient intake data were determined using dietary analysis. Weight, height and waist circumference were measured and body mass index (BMI) calculated. When starting college, student home economics teachers have broadly similar anthropometric, dietary and lifestyle characteristics to those of their contemporaries. Mean BMI was identical [24.4 kg/m² (SD 4.3)] to that reported in the North/South Ireland Food Consumption Survey (NSIFCS) for those aged 18–35 years, although energy intakes were significantly higher in the cohort of student teachers (P = 0.000). Thirty‐eight per cent were overweight or obese vs. 33.6% in the NSIFCS. Only 17% (n = 6) of students achieved an intake of 300 µg/day of folate as recommended by the Food Safety Authority of Ireland and only one the recommended intake of non‐starch polysaccharides (18 g/day). One in three students in this study smoke (16 of 48) and alcohol consumption was high. Only one student was very active. Students scored a mean of 55% (SD 8%) on the knowledge test, with similar scores attained for specific aspects of nutritional knowledge (i.e. food groups, constituents of foods, current dietary advice, nutrients, lifestyle practices). However, knowledge of nutrition definitions was weaker with a mean score of 31% (SD 8.6%). Students had a positive attitude towards food choice, the link between food and health and control over their own diet. Similar attitudes towards exercise, smoking and alcohol consumption were displayed despite students perceiving themselves as not having a balanced diet, having insufficient exercise and having regretted something done as a result of consuming alcohol. They appear to display optimistic bias in relation to health risks. These findings provide baseline data for the longitudinal study and indicate that those choosing to pursue a career as a home economics teacher in Ireland have similar nutritional and lifestyle characteristics to those of their contemporaries.     

Estimating the effects of nutrition label use on Canadian consumer diet‐health concerns using propensity score matching

The overarching goal of nutrition labelling is to transform intrinsic credence attributes into searchable cues, which would enable consumers to make informed food choices at lower search costs. This study estimates the impact of nutrition label usage on Canadian consumers’ (n = 8,114) perceived diet‐health concerns using alternative propensity score matching (PSM) techniques. We apply a series of tests and sensitivity analyses to overcome issues of endogeneity and selection bias frequently found in studies of diet‐health behaviour and to validate the impact of exposure to nutrition facts labels for users vs. non‐users. Our results support the notion that consumer uncertainty and related food‐health concerns are linked to their information behaviour, but not in straightforward manner. Dominant subjective food attributes, such as taste, convenience and affordability, may in fact outweigh the benefits of information about healthier, alternative food choices. In order to change dietary health behaviour, food manufacturer and policy makers alike need to adopt communication instruments that better account for differences in preferences, shopping habits and overall usage patterns of nutrition labelling information.     

The heuristic‐systemic model of sustainability stewardship: facilitating sustainability values,beliefs and practices with corporate social responsibility drives and eco‐labels/indices

Using a framework from the heuristic‐systematic model and the value‐belief‐norm (VBN) theory, this study tests consumers’ systematic conjunction of sustainability values, beliefs and practices, and examines the heuristic influence of sustainability stewardship on the consumers’ VBN framework. In this study, sustainability stewardship within the textile and apparel industry refers to approaches that can facilitate the corporate social responsible (CSR) drive and eco‐labels/indices in corporate sustainability practices. Data from 239 US college students were analyzed using a structural equation modeling method. The findings confirmed that only the CSR drive is significant as heuristic sustainability stewardship in facilitating the consumer's systematic process in the VBN framework, while eco‐labels/indices do not moderate consumers’ sustainable practices. In particular, the current CSR drives in the textile and apparel industry strengthen consumers’ values in the altruistic, self‐enhancement and biospheric dimensions, and, further, lead to the sustainability practices of eco‐citizenship, green consumption and green product purchasing, through the mediation of proenvironmental belief. Comprehending these dynamics can empower marketers and researchers to devise pertinent ideas and practical applications of sustainability stewardship to academia and to the textiles and apparel industry.     

Market orientation,organizational performance,and the mediating role of crowdsourcing in knowledge‐based firms

This paper establishes the relationships between market orientation and crowdsourcing in knowledge‐based firms for improving their organizational performance. By understanding the relationships among these variables, firms are in a better position to tackle complex business and innovation problems faster and at a lower cost. Results from the Spanish biotechnology and telecommunications sectors show the relevance of social networks for a better adaptation to rapidly changing markets and increasing competitiveness.     

Exploring the relationship between consumer knowledge and purchase behaviour of value‐based labels

Despite an increasing market presence, little research has been conducted regarding consumer‐purchase behaviour of food products bearing ‘value‐based’ labels. Moreover, as the effectiveness of these labelling formats is dependent upon consumer's knowledge of their existence, this paper aims to explore the relationship between knowledge, openness to experience (i.e. validated personality trait related to intellectual capability) and purchase behaviour upon consumer behaviour in this context. Using structural equation modelling techniques, causal influences on purchases of fresh meat bearing ‘value‐based’ labels are identified and three multi‐attribute attitude models are proposed. The paper concludes that these labels are of value to consumers and that product knowledge plays a significant role in aiding purchase decisions. Consequently, marketing communication implications arising from the proposed multi‐attribute attitude models are discussed.     

The role of parental influence and additional factors in the determination of food choices for pre‐school children

Every pre‐school child requires an adult to purchase and provide a variety of foods, to help ensure a balanced selection is included in the diet to avoid any nutritional deficiencies. Children under 5 years have a greater demand for nutrients and energy to support the body's requirements for growth and development than at any other time throughout their life cycle. The paper critically reviews the main factors that influence food choices made by parents on behalf of their pre‐school child. Dietary deficiencies in inner city areas remain a challenge for the government, educators and health professionals. A particular concern is iron deficiency as the prevalence of anaemia is common especially in British pre‐school children from various family backgrounds. Poor parenting skills often exacerbate the problem, especially the early introduction of pasteurized cow's milk, poor weaning practices and lack of dietary knowledge. Therefore, improving education and understanding about the importance of iron could potentially improve dietary iron intake. Phase 1 of the study was completed in West Bridgford area of Nottingham in the UK. This part of the study aimed to determine parental knowledge with regards to the feeding of their pre‐school child. A questionnaire and a 3‐day diet history method were employed. These methods enabled the diet adequacy of the pre‐schoolers to be analysed by NetWISP software. This study highlighted that iron deficiency remains a cause for concern and should be further addressed. The Sure Start programme is a possible means of education as it has the potential to access parents from all socio‐economic classes. The programme can support and empower parents to become healthier consumers. Good dietary habits, established early in life, contributes to a positive start, and can be advantageous to individuals throughout their lifetime. Such long‐term changes will help contribute to a healthier nation that the government envisages for the future.
