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.     

The Impact of Food‐Related Values on Food Purchase Behavior and the Mediating Role of Attitudes: A Swiss Study

Personal values and attitudes can help to explain food choice. This study confirmed a hierarchical organization of the value–attitude–behavior chain: Food‐related values influence attitudes, and these, in turn, impact behavior. Contrary to previous findings, values are only partially mediated by attitudes: Some food‐related values are fully mediated, whereas others are partially mediated, and still others have exclusively direct effects on purchase behavior. Questionnaire data from a roughly representative sample of 851 adults living in Switzerland was complemented with actual food purchase behavior measured by a loyalty card of a Swiss retailer over the period of one year. Four theoretically derived structural equation models were compared across eight different food product categories (organic, fair trade, low‐budget, fresh convenience, ready‐to‐eat, light, functional foods, fruits and vegetables). The results question central assumptions of the theory of planned behavior and emphasize the role of food‐related values in food consumption. Implications for marketing and future product developments of food companies are discussed.     

The role of food eating values and exploratory behaviour traits in predicting intention to consume organic foods: An extended planned behaviour approach

The extant literature on predicting organic food choice as a consumption behaviour has overlooked the role of food eating values (utilitarian and hedonic values) and individuals exploratory buying behavioural traits (exploratory information seeking and exploratory acquisition seeking). The novelty of the study is the use of food eating values and individuals exploratory buying behaviour traits as an extension to the theory of planned behaviour in predicting attitude and intentions towards organic food consumption with a representative sample of N = 431. Data was collected in two phases. In the first phase, a small qualitative face to face (semi structured) interviews were held from 22 respondents to elicit the utilitarian and hedonic values individuals attach with the organic food consumption. This is followed by the collection of survey data from two Indian metropolitan cities (New Delhi and Chennai) using a mall intercept method from the individuals visiting hypermarkets and supermarkets. The hypotheses were tested using structural equations modelling or SEM in IBM AMOS 24. Attitude to consume organic foods was found to be most dominant in predicting behavioural intention in both basic and the extended TPB model followed by subjective norms. Perceived behavioural control was found to be a significant predictor only in the extended TPB model, suggesting a dual role. Findings also suggested that utilitarian values are more influential than hedonic values in the formation of attitudes towards organic foods.Further, the exploratory information seeking traits are found to strengthen the relationship between a) perceived behavioural control and behavioural intention to consume organic foods and b) attitude to consume organic foods and behavioural intention to consume organic foods whereas exploratory acquisition seeking traits to be strengthening the relationship between attitude and behavioural intentions only. Implications for the policy makers is discussed towards the end of the study.     

Exploring convenience orientation as a food motivation for college students living in residence halls

The main objective of this paper is to study the concept of convenience orientation among young adults. A project was conducted among students living in residence halls, where information on their food motivation and behaviour was obtained. Data were collected using a self‐administered questionnaire filled out by 319 students. Convenience ap‐pears to be the most important food motivation followed by price, pleasure, health and concern about weight. Positive correlations were obtained between convenience and: deciding what to eat, having a varied diet and lack of time, all of which were considered to be difficulties associated with living in residence. Negative correlations were obtained between convenience and total time spent cooking per day and having learned to be autonomous in the kitchen. For male, the perception of eating well, having a varied diet, and maintaining weight were negatively correlated to convenience. For female, the correlation between convenience and the difficulty of eating enough was significant and positive. Negative correlations were obtained between convenience and fresh vegetables, potatoes, eggs, fresh meat, fresh fish and fresh poultry, herbal tea and alcohol. Positive correlations were obtained between convenience, frozen foods and foods brought from the parents’ home. Findings are discussed from both a health and a family perspective.     

Factors affecting consumer acceptance of chilled ready meals on the island of Ireland

The chilled ready meal market on the island of Ireland is relatively young but is growing rapidly. This paper focused on a consumer questionnaire (n = 702), designed to examine consumer attitudes to and consumption of chilled ready meals, in both the north and south of Ireland. This formed part of a larger study, with the questionnaire findings contributing to an in‐depth sensory study on a selected range of chilled ready meals. For a significant number of Irish consumers, consumption of these products is higher than on the UK mainland. For others, the products are purchased as a convenient alternative or a weekly treat. Respondents in urban locations were significantly more likely to consume chilled ready meals, as were men and younger, single respondents. Irish consumers are becoming more accustomed to ethnic cuisine although traditional meals remain popular. There is a clear need for developers to continue to enhance the sensory quality of these products, particularly as the primary barrier to consumption was a preference for home cooked food. However, they must also strive to maintain consumer interest in the sector, fulfil the desire for convenience and satisfy a more discerning palate.     

‘Don't give us an assignment where we have to use spinach!’: food choice and discourse in home and consumer studies

The aim of the study was to describe classroom Discourses about vegetables during the planning, cooking, eating and evaluation of meals in the Swedish school subject Home and Consumer Studies. Fifty‐nine students and five teachers were recruited from five northern Swedish villages and towns, and then observed, recorded and in some cases video‐taped during lessons that took place between 2010 and 2012. Based on 56 instances of talk about vegetables, four Discourses were identified and related to the three aspects of Belasco's culinary triangle of contradictions: identity, responsibility and convenience. The results indicated that the identity‐based sensory and cultural Discourses sometimes clashed with the more responsibility‐oriented health and evaluation Discourses. The health Discourse was only used when there was an element of evaluation, with assignments connected to grades. In all other cases, the sensory and cultural Discourses guided vegetable use. Sometimes different sensory or cultural assumptions could clash with each other, for example when the teacher insisted on the use of a specific recipe regardless of a student's taste preferences. Since these preferences did not always harmonize with curricular demands for responsibility, there might be a risk of basing grades on aspects of students’ identity. Alternatively, students might feel constrained to argue against their own identity in order to be favourably evaluated. Then again, if teachers always bow to student tastes, this limits their chances of learning about food and physical health. Viewing the dilemma through the lens of the culinary triangle of contradictions may help teachers and researchers develop teaching methods that take all aspects of food choice into account.     

Consumers' perceptions and awareness of safe food preparation practices at homes in Trinidad,West Indies

The objectives were to evaluate consumer perception and awareness of safe food preparation practices at homes. A questionnaire was self‐administered to 124 consumers who were primarily responsible for preparation of foods and owned a refrigerator at home. Data were analysed by frequencies and chi‐square. Most (97.6%) consumers considered safe food practices as ‘very important’. Few (8.9%) related Hazard Analysis and Critical Control Point to safe food preparation practices. Microbiological hazard was ranked as a most serious threat to food safety (80.5%). Salmonella was most well known (79.8%). Diarrhoea (23.7%) was a common symptom of food‐borne illness. More than 50% would ‘always’ check for expiry dates on labels, seals and would never purchase swollen cans. Only 48.4% consumers used separate cutting boards for meats and vegetables ‘always’. Some (6.5%) felt it was appropriate to give unfit food to someone else. The study identified critical points in safe food preparation practices for effective public health education.     

Key influencing factors of green vegetable consumption in Beijing,China

Green-certified vegetables are nutritious, attractive to the senses, and in line with the principles of sustainable development. The objectives of this study are to reveal the mechanism of green-certified vegetable consumption; that is, to explore the key influencing factors behind consumers' purchase intentions, purchase behavior, and willingness to pay for green-certified vegetables. Based on the Theory of Multi-attribute Attitudes and the Theory of Planned Behavior, a research framework of the consumption mechanism oriented to consumers' preferences regarding green-certified vegetable quality was established. By collecting 520 questionnaires from Beijing, China, the model was confirmed by the ordered logistic regression and interval linear regression method. The results showed that consumers have heterogeneous quality preferences, and their purchase intentions and purchase behavior levels are relatively high, with an average willingness to pay (WTP) of 138.58%. The key influencing factors driving consumers' purchase intentions, purchase behavior, and WTP include protein content belief, mineral content belief, vitamin content belief, organic vegetable safety belief, freshness belief, and taste belief. In addition, color belief and packaging quality belief significantly influenced consumers' WTP, while origin reputation belief and brand reputation belief significantly influenced consumers' purchase intention and purchase behavior. The findings of this study can guide the supply side of green-certified vegetables to improve product quality according to consumer demand, so as to promote the sustainable development of green-certified vegetables.     

“As Much Calcium as a Glass of Milk!” Understanding American Consumers’ Preferences for Fortified Foods

This study examines predictors of American consumers’ preferences for fortified foods, focusing on sociodemographic as well as psychological correlates. Analysis of a probability-based survey (N = 6,728) revealed that females and the more educated tended to have greater preferences for fortified foods. Whites held the least favorable views on fortified foods when compared to Blacks and Hispanics. In terms of psychological predictors, people who were more health-conscious were more likely to prefer fortified foods. Perceived usefulness of nutrition labels and confusion about healthy food choices were both associated with stronger preferences for fortified foods. Both relationships appeared to be moderated by health consciousness. Communication and policy implications of these findings are discussed.     

Sodium and ready meals: a survey of Irish consumer awareness

The aim of the study was to gain an understanding of Irish consumer attitudes towards ready meals and current sodium issues in Ireland. A questionnaire was distributed to 357 consumers via convenience quota sampling to a range of nationalities in both rural and urban/city areas of Ireland. The survey revealed that a high proportion of respondents (45%; n = 161) were worried about the amount of salt they consumed. Despite this, 58% (n = 207) stated they never look at the sodium/salt contents on nutritional labels with 68% (n = 244) claiming that sodium/salt contents would never affect their buying choice. The survey also uncovered that 76% (n = 270) of the Irish consumers surveyed consider ready meals to be high in sodium and 80% (n = 285) consider them to be an unhealthy option. Despite this, 50% (n = 179) of the respondents consumed a ready meal at least once a week with a further 17% (n = 59) consuming them two to three times a week. Of those who did consume ready meals, 78% (n = 191) chose them due to their convenience. A total of 75% (n = 269) of all the respondents said they would choose a chilled ready meal over its frozen counterpart. The reason for this being attributed to the fact that chilled ready meals were perceived to be healthier (44%; n = 158) and of better quality (54%; n = 194) than their frozen counterparts. Results from this study highlight the need for concerted actions involving consumers, manufacturers and retailers to reduce sodium levels in Irish ready meals, as despite being reasonably aware of the sodium issue consumers were not making informed choices to reduce sodium/salt consumption.     

The link between diet and health: an exploratory study of adolescents in Northern Ireland using foodmaps

A significant proportion of consumers in the UK continue to adopt a diet consisting largely of nutritionally unbalanced foods. The adolescent period has been identified as being formative in the development of long‐term eating habits as the individual achieves greater control over their food choice. By examining the current eating behaviour of a sample of adolescents, the aim of this study was to establish why they are not utilizing their knowledge to choose nutritionally balanced foods. A two‐stage data collecting procedure was adopted. In stage 1, respondents (n = 136) completed a questionnaire that measured demographic and social factors, knowledge, attitudes, pre‐existing behaviour with respect to food and the influence of family, peers, the media and government campaigns on their eating behaviour. In stage 2, a subsection of the respondents (n = 20) completed a foodmap, which revealed the network of relationships involved in the adolescents' decision‐making process by identifying the links among the foods consumed, the people they eat with and the places they eat in. Results emphasized the importance of the home environment and the continuing influence of parents on adolescents' eating behaviour despite the greater independence related to this stage of the life cycle. A proportion of the sample was found to have recognized the need to change their eating behaviour in order to lose weight, because of their sporting commitments or to improve their health. Recommendations from this study include the need for the various agencies involved in the promotion of balanced dietary behaviour to attend to the link among adult, family and adolescent, and the need for greater progress in enabling consumers to translate the theory of nutritional education into practice.     

An experimental investigation of the effect of TV cooking show consumption on children's food choice behaviour

For several decades, television consumption has been crucial in the complex web of factors underlying the obesity epidemic. It has been suggested that if television cooking shows would endorse healthy eating styles, they may have positive effects on consumers’ eating habits. This study empirically investigated the consequences of exposing children (N = 85, aged 9–12 years) to an existing television cooking show episode endorsing the consumption of fruits and vegetables compared with exposure to a non‐food‐related science show. The measures included pre‐test and post‐test attitudes toward health/nutrition and fruits/vegetables, as well as state preferences for a list of healthy and unhealthy foods. At the end of the study, children were separately given the choice between a popular cookie and a piece of fruit as a reward; this was used as a behavioural measure. The results of a logistic regression on the behavioural choice measure showed that the mere exposure to one episode of the television cooking show significantly increased the odds that the children would choose a piece of fruit over a cookie. Repeated‐measures analyses showed that watching this single episode also decreased children's state appetite for unhealthy foods. State appetites for healthy foods and attitudes toward health/nutrition or fruits/vegetables did not change after watching the television cooking show episode. In sum, existing television cooking shows that endorse healthy eating positively influence children's food consumption in the short term and may have the potential to be used as platforms for nutrition education.     

Parental work status and children's dietary consumption: Australian evidence

This study investigated associations between parents' work status and the dietary consumption patterns of Australian children, and whether such associations vary by parental education and usage of nonparental childcare. Data from the longitudinal study of Australian children at two waves from ages 2–3 years (n = 4601) to 4–5 years (n = 4381) were analysed. Logistic regression models were used to calculate odds ratios of children consuming (≥1 times/day) fruit and vegetables (FV), high fat foods (HFF), high sugar drinks (HSD), as well as evaluating the incidence of breakfast consumption. This was analysed against the employment status of parents including full‐time, part‐time and unemployed. Children of part‐time employed mothers were more likely to consume breakfast, and less likely to consume HSD compared with children of full‐time employed mothers. Children of part‐time employed fathers were less likely to consume FV and breakfast, and more likely to consume HSD compared with children of full‐time employed fathers. Children of nonemployed mothers were more likely to consume HFF, whilst those of nonemployed fathers were more likely to consume HSD and less likely to consume breakfast compared with other children. Amongst less‐educated parents, children of unemployed and part‐time employed parents were more likely to consume HFF and HSD and less likely to consume FV and breakfast compared with children of full‐time employed parents. Amongst highly educated parents, children of unemployed and part‐time employed mothers were less likely to consume HSD compared with children of full‐time employed mothers. Children of part‐time employed mothers who used family day care, day care centres and grandparent care were less likely to consume HSD and more likely to consume breakfast compared with children of full‐time employed mothers. Children of part‐time employed fathers and unemployed parents who used day care centres and grandparent care were less likely to consume FV and more likely to consume HFF compared with children of full‐time employed parents. Future studies should pursue a better understanding of the mechanisms for the adverse effects of parental work status on dietary consumption to develop and enhance specific interventions targeting these groups.     

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.     

“I don't like wonky carrots”- an exploration of children's perceptions of suboptimal fruits and vegetables

Children's perceptions of suboptimal fruits and vegetables have not been studied in the suboptimal foods domain. Using two qualitative research methods, this study investigates children's (N = 97) edibility perceptions of suboptimal produce with varied appearance defects. The results show that unlike adult samples previously studied, children are more accepting of suboptimal produce. Defects in shape, size, and certain colour defects were positively perceived, reflecting retailers' opportunities to market suboptimal produce. High levels of brown discolorations and superficial blemishes were not acceptable, implying that produce with such defects could be repurposed as ingredients in foods prepared and sold in-store. These implications reflect retailers' opportunities in marketing suboptimal produce to children, who by their familial influence may also be able to get families to buy and consume suboptimal produce. The importance of familiarity in improving suboptimal food acceptance is also recognised for future research to explore.     

Food appearances in children's television programmes in Sweden

Studying other television content than advertisements is necessary to better understand the association between TV viewing and dietary habits. The aim of this study was to examine the nature and extent of verbal and visual appearance of food and beverage in children's programmes in Swedish public service television. The study object was the most popular children's TV programme in Sweden, broadcast by commercial‐free public service television channel and watched almost daily by 45% of children under the age of 10 years. The analysed material consisted of 25 h, broadcast at 21 occasions over almost a 5‐month period of the most popular TV viewing season. All appearances and type of food and beverages were coded as well as the context in which the foods were discussed or appeared. Chi‐square tests were performed to analyse if the occurrence of fruits and vegetables and high‐calorie and low‐nutrient (HCLN) foods respectively were associated with the context where food appeared. Mann‐Whitney test was used to compare the representation of the two food groups in terms of degree of propensity to be consumed. Of the 287 programme sections, food or beverage appeared in 78%. Of the food appearances (n = 773), HCLN foods constituted 19%, and fruits and vegetables 39%. More than half of the HCLN food appearances are with children, while only one third of the fruits and vegetables are shown with children. HCLN foods were more often shown being consumed or actively handled, than fruits and vegetables. Food and beverages appear frequently in children's programmes in Swedish public service television. HCLN foods seem to be represented as more attractive, by to a greater extent appearing consumed or actively handled in comparison with other foods. These foods were also frequently shown together with children while fruits and vegetables more frequently appeared with adults than children.     

Comparison of fruit and vegetable consumption among Native and non‐Native American populations in rural communities

Fruit and vegetable consumption of Native Americans was compared with that of non‐Native Americans and determinants of fruit and vegetable intake for both populations were found based upon the Theory of Planned Behavior. A one‐time survey was conducted as part of a larger research project funded by the South Dakota Department of Health. The survey was administered in local grocery stores and supermarkets in six South Dakota communities, including two located on Native American reservations. Of the 1000 distributed surveys, 499 were returned with 230 being usable, resulting in a response rate of 49.9%. Wilcoxon signed‐rank test and two regression models were tested using SAS 9.2 software. Dependent variables were fruit and vegetable intake. Attitudes towards health, fruit and vegetable consumption, perceived difficulty, subjective norm and intention were also measured. Community size, family income, employment status and participation in food assistance programmes [Supplemental Nutrition Assistance Program or Women, Infants, and Children (SNAP or WIC)] were socio‐demographic control variables. Overall, Native American participants consumed more fruit and vegetables at home and had a more positive attitude towards healthy diets than non‐Native American participants. SNAP or WIC participation, family health, exercise, intention to live healthier than parents, buying healthy food, and fruit and vegetable consumption when eating out were positively associated with fruit and vegetable consumption among Native Americans, while participation in the SNAP or WIC programme had a negative influence on consumption among non‐Native American participants. Family health, exercise, buying healthy food, fruit and vegetable when eating out, and intention to buy healthy food were positively associated with fruit and vegetable consumption among the non‐Native American population. Theory of Planned Behavior variables (e.g. attitude towards healthy food) significantly contributed to the model explaining fruit and vegetable consumption. The fact that SNAP and WIC participation had an opposite influence on the two populations warrants further research.     

Determining female consumers’ perceptions of garment fit,personal values and emotions when considering garment sizing

Female consumer's clothing shopping experience is primarily influenced by the appearance and fit of a garment that may be influenced by their personal values and is a process that involves emotions (Otieno et al., 2005; Lopatovska and Arapakis, 2011). Very little research focussing on the emotional impact and the role that personal values play in the female consumers’ shopping experience of ready‐to‐wear garment fit has been conducted in South Africa to date. The primary objective of this study was to explore the areas of concern of garment sizing to establish the emotional impact garment sizing and the resulting fit have on the female consumer purchasing behaviour when evaluated against their personal value system. This study applied the means‐end chain theory approach that allowed the researcher to explore female consumers’ personal values and the resulting emotions, through the application of the laddering interview techniques. Using open‐ended questions, this study aimed to discover the role of female consumers’ perceptions of garment sizing and the resulting emotional effects of garment fit on their purchasing decisions. The findings from the data collected from a purposeful and convenient sample of 62 female consumers from Gauteng, Johannesburg showed that the majority of the participants in this study failed to attain their personal values through the fit of a garment due to inconsistent, unreliable and inaccurate sizing, garment sizing which is unsuitable for various body shapes and the unavailability of certain clothing sizes in ready‐to‐wear garments. The study established that it is extremely important that South African clothing manufacturers and designers should strategize to satisfy the clothing need of the consumers who are currently having problems with garment sizing, by understanding female consumers’ garment sizing and fit needs through extended research of their target markets.
