Factors influencing unhealthy eating behaviour in US adolescents

This research explores the simultaneous effects of key variables on unhealthy eating behaviour. Specifically, this study focuses on the relative effects of advertising, parental and peer influence, and self‐efficacy on the unhealthy eating behaviour of US adolescents. The results suggest that: (1) parental influence, peer influence and self‐efficacy significantly predict unhealthy eating behaviour; (2) self‐efficacy is the strongest predictor of unhealthy eating behaviour; and (3) advertising effects are largely neutralized by parental influence, peer influence and self‐efficacy.     

Factors that influence the consumption of food outside the home in Brazil

The food sector has taken on an unprecedented dynamism in recent years. The processing and distribution of food, although heavily influenced by tradition, have seen intensive innovations, leading to changes in the way individuals consume. One of these changes is the consistent growth of the habit of eating outside the home. Consuming food outside the home involves a number of practices such as eating at commercial establishments that specialize in food (restaurants, fast food restaurants and snack bars) and those that offer food as a part of their services (hotels, in‐flight meals), and non‐commercial alternatives such as the homes of family and friends. In order to describe the eating habits of consumers in the town of Lavras in Minas Gerais State, Brazil, especially when it comes to eating outside the home, a quantitative study was conducted, with 413 questionnaires being distributed by convenience sampling. Among the main results are: (a) a search for variety as a motivator for eating outside the home; (b) convenience as an important element on many occasions of consumption; (c) more intensive consumption and more favourable attitudes towards eating out on the part of younger people, people with higher incomes, no children and a higher degree of schooling; (d) importance of paying for food by the kilo. When compared with a study conducted in England, important similarities were identified in socio‐demographic influences, although the cultural factors are notable when it comes to dishes and the types of eating establishment. The growing habit of eating out has therefore become a worldwide phenomenon, but with cultural and regional differences that have led to different rhythms in terms of change and the way food is supplied. The recovery of embedded cultural habits, with increased value being given to slow food, traditional dishes and tradition itself, appears to co‐exist with a productivity model of food courts, pasteurization and accessible prices. The occasion for consumption, which may be understood as the dichotomies of ‘weekday versus weekend’ or ‘convenience versus leisure’, is an important element that influences consumer behaviours. The undertaking of a cross‐cultural comparative study can be seen as an important step in this field of research.     

Reduced‐fat foods: the shopper’s viewpoint

The inclusion of reduced‐fat foods in the daily diet affords consumers the potential to reduce overall dietary fat. Nevertheless, despite an increased range of these food products throughout the market, there has remained a lack of widespread consumer acceptance. The aim of the study was therefore to understand why consumers choose or reject reduced‐fat foods. Ninety consumers were interviewed by means of a qualitative approach within food retail outlets in the United Kingdom. Thematic content analysis indicated that uptake or rejection of these products is influenced by health concerns, ‘goodness of fit’ with individual dietary health strategies, the preferences of different household members, perceived sensory properties and scepticism towards these products. The results imply a need to explore and innovate ‘natural’ fat substitutes and to improve the sensory quality of reduced‐fat products. Further research is required to determine how these foods are used within the household and incorporated within the overall diet. Policy must seek to restore consumer trust in reduced‐fat food products and the food supply generally.     

Finns and functional foods: socio‐demographics,health efforts,notions of technology and the acceptability of health‐promoting foods

Eating is increasingly characterized by concerns over health and well‐being. New types of foods designed to promote health or to reduce the risk of diseases, known as functional foods, have been entering the market since the 1990s. This article focuses on the appropriation of functional foods among Finnish consumers from the perspective of acceptability. We analyse the relationship between consumers’ views of functional foods and their socio‐demographic backgrounds, health efforts and notions of food, health and technology. The article is based on a survey of a representative sample of Finnish consumers (n = 1210). The data were collected by using computer‐assisted telephone interviews and analysed by factor analysis and analysis of variance. The factor analysis resulted in four dimensions of acceptability: (1) experiences of functional foods; (2) views on product quality and safety; (3) societal concerns over current developments; and (4) views on regulation and research. According to the results, the differences in consumer views of functional foods were to some extent linked with age and education but better explained by the differing roles of food and health in people’s lives and the acceptability of modern food technologies. Efforts to lower blood cholesterol and/or blood pressure, the use of dietary supplements, regarding healthy eating as very important and having an optimistic outlook on the use of technology in food production were all related to more optimistic views of functional foods. Finns seem to have a relatively trusting position on functional foods. Familiarity of functional foods in Finland, absence of serious food scandals, the health‐oriented Finnish culture and the generally high level of societal trust may account for this optimism.     

Social marketing and consumers’ experience of lipophobia

Modern societies are lipophobic: they express a deep anxiety about fat and fatness. On the other hand, the public discourses about health and well being, though biased towards lipophobia, are far from unanimous. The general question is how consumers experience and negotiate contradictory messages of hedonism and ascetics from commercial and governmental agents? This study more specifically examines the hypothesis that the governmental campaigns and official messages mediated through TV, newspapers and other media are largely failing their target, since they tend to have the biggest impact on people, that do not have a serious weight problem, but who nevertheless perceive themselves to be overweight. This is investigated through an adapted use of the Zaltman Metaphor Elicitation Technique approach with 20 younger female informants as well as a set of interviews with selected medical and political experts and representatives of consumer groups. The results provide a culturally rooted image of consumers’ fat intake and dietary practices as well as an attempt to de‐stigmatise consumers’ body imagery, informing future food policies and the food industry's satisfaction of public and private interests in consumers’ dietary patterns. This ends up in a critique of a certain approach to social marketing in the food domain. Rather than focusing on informational campaigns spreading messages that are already known to most people, more efforts should be put into the basic build‐up of a better general food culture – one that stresses quality over quantity and which is lipo‐conscious rather than lipophobic.     

Cooking,recipe use and food habits of college students and nutrition educators

The purpose of this study was to revisit Lewin's gatekeeper theory to observe current food role patterns (cooking experience, recipe sources, and both daily food consumption choices and eating out) with contemporary groups of college students (n = 292) and of nutrition educators (n = 26). Male college students equalled female students in cooking ability, use of family as a prime recipe source, and frequency of eating out, while exhibiting different food consumption excesses and deficiencies. Package labels and the Internet were most frequently identified as recipe sources by college students. Nutritionists surpassed both male and female college students in most attributes.     

Secondary school tuck shop options and student choices: A cross‐sectional survey

Obesity in children is rapidly becoming a major public health problem in Hong Kong; the prevalence of overweight in children increased from 16.2% to 22.2% between 1998 and 2008. Healthy eating programs and policies exist, but only for primary schools, and students’ eating habits change when they are exposed to the new environment in secondary schools. Therefore, this study examined the relationship between available food in secondary school tuck shops and students’ purchasing preferences. A cross‐sectional survey was conducted from mid‐March to mid‐April 2016 across six secondary schools, using a questionnaire to measure students’ healthy eating knowledge and eating habits and a checklist to explore food options in each school's tuck shop. Linear regression was used to explore the relationship between eating knowledge and eating habits and logistic regression to explore the relationship between available foods at the tuck shops and the children's purchasing preferences. A total of 374 junior secondary students participated in the survey. A weak, positive correlation was found between healthy eating knowledge and healthy eating habits. No association was found between available food at tuck shops and children's purchasing preferences. The results reveal a definite knowledge‐attitude gap where healthy eating is concerned. Despite there being no significant association between the food offerings in tuck shops and students’ measured purchasing preferences (p > .05), 81% of the students stated that they would choose healthy food if offered, illustrating the urgent need to assess the variety and nutritional quality of foods available in secondary school tuck shops.     

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.     

Budget over health unless overweight: A Solomon four‐group study

Budget and health motivations for food purchase (e.g., discounts and health consciousness, respectively) affect consumer choice while shopping and well‐being afterward. However, not all findings from research have suggested that discounts/taxations on healthy/unhealthy food encourage health‐conscious food choice. On the other hand, the consumer behaviour line of research on the influence of front‐of‐package health messages has mostly echoed similar results that such communication leads to overconsumption; thus, obesity. We examined the influence of market practices targeting consumers’ budget and health‐related motivations for food purchase in a 2 (price: recommended retail price, discount price) × 2 (product: regular potato chips, potato chips with ‘75% less saturated fat’) experiment using six Solomon four‐group designs. Our results indicate that overweight consumers are not prone to discounts, unlike their normal‐weight counterparts. A price cut nullifies the influence of health messages on purchase intentions among normal‐weight buyers when the regular and healthier packaged foods are both on discount.     

The influence of age and gender on food choice: a focus group exploration

With 25% of the UK population predicted to be obese by 2010, the costs to individuals and society are set to rise. Due to the extra economic and social pressures obesity causes, there is an increasing need to understand what motivates and prevents consumers from eating a healthy diet so as to be able to tailor policy interventions to specific groups in society. In so doing, it is important to explore potential variations in attitudes, motivation and behaviour as a function of age and gender. Both demographic factors are easily distinguished within society and a future intervention study which targets either, or both, of these would likely be both feasible and cost‐effective for policy makers. As part of a preliminary study, six focus groups (total n = 43) were conducted at the University of Reading in November 2006, with groups segmented on the basis of age and gender. In order to gather more sensitive information, participants were also asked to fill out a short anonymous questionnaire before each focus group began, relating to healthy eating, alcohol consumption and body dissatisfaction. Making use of thematic content analysis, results suggested that most participants were aware of the type of foods that contribute to a healthy diet and the importance of achieving a healthy balance within a diet. However, they believed that healthy eating messages were often conflicting, and were uncertain about where to find information on the topic. Participants believed that the family has an important role in educating children about eating habits. Despite these similarities, there were a number of key differences among the groups in terms of their reasons for making food choices. Older participants (60+ years old) were more likely to make food choices based on health considerations. Participants between the ages of 18–30 were less concerned with this link, and instead focused on issues of food preparation and knowledge, prices and time. Younger female participants said they had more energy when they ate healthier diets; however, very often their food choices related to concern with their appearance. Older female participants also expressed this concern within the questionnaire, rather than in the group discussions. Overall, these results suggest that consumer motivations for healthy eating are diverse and that this must be considered by government, retailers and food producers.     

The golden age of protein: an initial teacher training perspective on the biological role of proteins in our everyday lives

We make use of proteins in all aspects of our daily lives from biological washing powders to soft‐centred sweets, yet their fundamental role in our diet is often misunderstood. This paper draws on the findings of a three‐phase research project into Initial Teacher Trainee's perception of food and eating, where students demonstrated several similar misconceptions about the food they eat and in particular, the role of proteins. More than 50% of the students thought that protein was a primary source of energy and were confused about the relationship between proteins, amino acids and nitrogen, and the role of DNA in synthesizing proteins. These misconceptions were often translated into practice in the diet the students consumed and the messages they passed on, with confidence, to their pupils. In addition to the misconceptions, teaching approaches used by the students were highly mechanistic, with little reference being given to the relationship between food and the circumstances in which it is eaten. The relationship between dietary intake and lifestyle is explored in secondary schools within Food Technology lessons. However, it is often too late to rectify the deeply entrenched misconceptions, attitudes and eating habits that school children have developed in their primary years. This paper makes the recommendation that we should reconsider how nutrition education is delivered in schools, especially at a primary level: emphasizing the need to relate teaching and learning to everyday experiences. The paper concludes by suggesting possible strategies by which this may be achieved, with proteins featuring centre‐stage.     

Food consumption,lifestyle patterns,and body mass index of a group of white South African students

There is worldwide concern that higher education students are increasingly engaging in unhealthy eating and lifestyle practices. A total of 488 white students participated in a study aimed at investigating the current food consumption and related lifestyle patterns of students at a South African residential university. The respondents’ self‐reported weight and height was used to calculate their body mass index (BMI). Closed and open‐ended questions measured aspects of the respondents’ usual eating patterns and lifestyles. The meal patterns and composition confirmed Western‐orientated food practices, as the majority consumed three meals a day, with in‐between meal snacking, and a different meal pattern over weekends. Respondents’ food intake was further characterized by a low intake of fruit, vegetables, and dairy products and frequent consumption of foods high in fat, sugar, and sodium. Although the majority (66.8%) of the study group were classified as normal weight according to their BMI, when comparing males and females, more males than females were overweight and obese. Only 54% of the males had a normal weight compared to 82% of the females. There was, however, no statistically significant difference (p = 0.149) between how males and females in the different BMI groups felt about their weight. The study also explored the relationships between the respondents’ BMI, gender, food consumption patterns, and type of residence. The features of the food consumption patterns were depicted according to whether breakfast was eaten or not; snacking activity between meals; the consumption of ready‐prepared convenience meals, fast foods; home‐cooked meals; and eating out. There were no statistical significant differences between the BMI categories of males and females regarding their habit to eat breakfast or not; and to snack between meals either during the morning, in the afternoon or after supper. Similarly, no statistical significant differences were noted when relating the BMI categories of the gender groups to the frequency of consumption of ready‐prepared, convenience type meals, fast foods, and home‐cooked meals. However, a statistical significant difference (p‐value 0.006) was found between BMI categories per gender and general frequency of eating out. No statistical differences was noted between BMI categories, gender and place of residence irrespective of the type, whether the student lived with parents, independently in a flat or apartment, or a house with friends or a room, or in a university residence.     

Consumer demand for healthy eating considering diversity – an economic approach for German individuals

Rising incidence and costs of diet‐related diseases have led to nutritionists' and economists' interest in factors determining the demand for healthy eating. The present study analyses the demand for healthy eating by the use of a new food‐based indicator, which combines the health value and diversity of a food basket. Although the diversity aspect gains in importance in recommendations for healthy eating it was not considered adequately in healthy eating indicators until now. Within the household production theory the new indicator is used to identify factors influencing the demand for healthy food diversity for 3220 German individuals. The results of regression analyses show that the demand for a healthy diet is influenced by age and mainly by knowledge, attitudinal and behavioural (proxy‐)variables as education level, participation in a health training course and sport activity. On the basis of these findings conclusions are drawn for health and nutrition policy in Germany and Europe.     

Development of functional food with the participation of the consumer. Motivators for consumption of functional products

The purpose of the study was (1) to define the most important characteristics of functional food affecting purchasing decisions; (2) diagnose the importance of the healthful properties of functional food; (3) identify preferences for carriers (base product) and the importance of the functional components essential in the choice of functional products; and (4) get to know the motives by which consumers are guided when purchasing functional food. The data were collected through direct interview (n = 200). The research tool was a questionnaire divided into four sections. The first one included quality attributes. The second one included healthful properties, functional components and carriers. The third one concerned the motives for purchasing functional food and included the consequences and values. In the fourth section the participants were asked about gender, age and education. The results of this study allowed determining the most important attributes of functional food products. Among quality attributes the most important are safe food, natural product and healthy product. The most important organoleptic attributes include nice taste. Very important attributes of packaging and labelling include expiry date and information on the healthful properties of the product. The most important healthful properties are associated with the attributes (1) strengthens the immune system; (2) reduces the risk of certain cancers; (3) reduces the risk of cardiovascular diseases; (4) helps maintain the correct body weight; (5) strengthens eyesight; (6) improves memory; and (7) improves physical condition. The functional components concern mainly vitamins and minerals, omega‐3 fatty acids and dietary fibre. As the best base products, consideration was given to bread, dairy products, cereal products, mixtures of fruits and vegetables and meat products. In the motivation system there were distinguished functional consequences that included improvement of health, needs of the organism, and healthy eating and psychological consequences such as conscious choice and health promotion. The most important autotelic values include good health and long life, health safety, inner harmony, self‐respect and self‐confidence. The means to achieve these goals are responsibility for health and care for health. The study provides bases for a better understanding of the consumer's needs and optimization of activities related to the development and consumption of functional food. The results of this study may provide valuable support for actions connected with the promotion and marketing of food products.     

Eating fast food: attitudes of high‐school students

Alarmingly consistent recent research shows that industrially produced foods such as fast food contain compounds that add to obesity and high cholesterol among young people. Less physical activity and a higher propensity to eat ready‐made food (in Sweden and internationally) have aggravated the health situation for the young generation. They also have become ‘addicted’ to sugar by the consumption of lemonade and other sweet drinks that are often served in conjunction with fast food. Food consumption patterns are highly cultural, and, once formed in early years, they become difficult to change. The findings of this study, which was based on a small sample of written accounts and transcribed interviews, indicate that high‐school students in Sweden are well aware of the good and bad attributes of fast food, such as: speed, convenience, fat and sugar. Clear differences in attitude were found between male and female students: female students view fast food in a broad food chain context, whereas male students concentrate on fast eating and satiety.     

Independent decision making of adolescents regarding food choice

The adolescence period is the stage in the life cycle in which individuals begin to develop independent decision making related to their social environment including their dietary intake. The period is fundamental in the development of longer term eating habits that may be reflected in adulthood. This study aimed to investigate the decision‐making process of adolescents and their dietary behaviour in the achievement of a balanced diet and to determine the underlying factors that may affect these choices. To meet this aim, a three phase data collection was utilized. In phase 1, a baseline questionnaire (n = 239) measured factors affecting dietary behaviour and the barriers in the achievement of a balanced diet. Phase two employed and measured respondents’ (n = 235) independent decision making by rating nineteen menu choices which reflected all options of dietary guidelines. This was analyzed through conjoint analysis. In phase three a subsample (n = 55) from the first two phases completed a food map which determined underlying reasons for food decisions and choice behaviour. Results revealed that when adolescents are given free choice they tend to follow an unbalanced diet with some diets raising concerns for their current and future health. Fifty‐seven percent of respondents displayed serious concerns in their dietary choice of which 18% were identified as requiring immediate intervention. The most noticeable factors affecting dietary choice were the desire to eat foods high in fat and carbohydrates and low in fruit and vegetable consumption. Food‐mapping indicated prior knowledge and attitudes had no effect on the choices made but that that behaviour of parents in the preparation of meals at home and peers in the selection of snack choices had the most influence on the unbalanced diet.     

Healthy eating habit: A role for goals,identity, and self‐control?

Supporting healthier eating habits is crucial for improving population health outcomes. Underpinning everyday eating patterns are recurring actions that may lead to positive or negative health outcomes depending on the healthfulness of such actions. The aim of this research was to explore individual‐level determinants of a healthy eating habit and consider to what extent personal goals and self‐control are linked to a healthy eating habit. One thousand one hundred nine adults completed a survey focusing on a range of factors that potentially sway food choice behaviors. A structural model, developed based on a review of existing literature, was tested using self‐reported healthy eating habit (Verplanken & Orbell, 2003 ) as the dependent variable. Analysis suggests that along with health‐conscious identity and food hedonism, self‐control was one of the strongest determinants of a healthy eating habit. Furthermore, while healthy eating goals had a direct significant effect, other goals, economizing and emotional, did not. However, all three goals along with food hedonism had a significant indirect effect that was mediated through self‐control. In revealing the role of self‐control, this work questions the underlying assumption of automaticity in a healthy eating habit. This leads to the questions: what is a healthy eating habit and to what extent can healthy eating behaviors ever be truly characterized as controlled by heuristics and automaticity? This analysis suggests that healthy eating is an ongoing behavioral project that requires the continued engagement of deliberative processes; thus habit within this context, and as measured using self‐reported habit, may be a misnomer. The use of healthy eating routines, as opposed to habits, may be more appropriate to acknowledge the role of both automatic and deliberative processes with self‐control being central in everyday decision making. Important practical and theoretical implications are discussed along with potential approaches for health and food sectors to support healthier eating behavior in the future.     

Not all organic food is created equal: the role of product type,perceived authenticity,and construal level

Abstract

Consumption of processed organic food is on the rise while fresh organic food still dominates organic food market. Drawing from the literature on authenticity and construal level theory, this study aims to investigate the role of perceived authenticity and message construal level in consumers’ evaluations of two types of organic food (fresh vs. processed). Two experiments were conducted among college students (N = 129, Study 1) and adults 18–70 (N = 249, Study 2). Our findings suggest that consumers’ evaluations of organic food are fully mediated by perceived authenticity of each organic food type. Specifically, compared to processed organic food, consumers perceive fresh organic food more authentic, which leads to more favorable attitudes and higher purchase intention. This research further demonstrates that the indirect effect of organic food type via perceived authenticity is moderated by construal level of marketing messages. That is, when messages are construed at a low level, consumers tend to have more positive attitudes and higher purchase intention toward fresh than processed organic food. By contrast, product type makes no difference when messages are construed at a high level. These findings have clear implications on message development strategy when promoting processed organic food, in particular. Future research directions are discussed.     

The food pyramid challenge

Pyramid Power is a 1‐hour programme designed to teach food choices, serving sizes and nutrition. Participants (19 women and 8 men) were challenged to follow the recommendation in a step‐by‐step manner. Evaluation, two months after the programme, resulted in two major areas of change. Participants improved their scoring of three food groups (bread‐cereal‐rice‐pasta, vegetable and fruit) and decreased the number of fat–sweet mentions. The programme and challenge provides a way for nutritionists to identify what participants are eating, to track progress and to identify future programme needs.
