Abstract

Purpose

Dietary supplements have been subject to considerable criticism because of their lack of regulation and questionable claims; yet, research indicates that consumers who are more health conscious are more likely to use supplements because the products are associated with preventive health behaviors. This research aims to examine whether consumers’ familiarity with supplement advertising or their level of health consciousness significantly affects their attitudes toward three different types of dietary supplements. It also assesses whether advertising familiarity and health consciousness are related to perceptions of supplement price.

Design/methodology/approach

This paper used a point-of-purchase approach and collected data at a nationwide supplement retail store in a major metropolitan area in the southeast, resulting in a final sample of 136 consumers. In addition to the survey items, data were collected on a number of demographic factors, including gender, age, marital status, race and education.

Findings

Results suggest that health consciousness is significantly related to attitudes toward different supplement types and perceptions of supplement price, but familiarity with supplement advertising is not related.

Practical implications

The results suggest that health consciousness is a significant predictor of attitudes toward different nutritional supplements and the perceived price of supplements, but familiarity with advertising is not a predictor. Implications for marketers and public policy are provided.

Originality/value

While this research informs public policy, it is especially useful for marketers and advertisers of dietary supplements.

Abstract

Purpose

Obesity is a chronic disease that is conjoined with increased mortality. Parallel to rising obesity rates, herbal dietary interventions to lose weight are also increasing. The purpose of this study is to assess and evaluate the use of herbal dietary interventions for weight loss among regularly exercising women.

Design/methodology/approach

A total of 545 regularly exercising women (aged 19–64 years) were recruited from several local sports centers. A questionnaire form to evaluate demographic characteristics, nutritional habits and herbal dietary intervention habits was administered by a trained dietitian. Anthropometric measurements including weight, height, fat mass, total body water and fat free mass were measured using a bioelectrical impedance analysis device.

Findings

A total of 244 participants (44.8%) used herbal dietary interventions for weight loss within the last year. The most commonly used herbal dietary interventions were green tea (59.4%), lemon juice (27%), herbal tea mix (20.9%) and cinnamon powder (17.6%), respectively. Of the 244 women who used herbal dietary interventions for weight loss, 42.2% claimed that by using these products they experienced weight loss. Herbal dietary interventions were significantly higher among women with obesity (61.9%) than women with a healthy weight (37.5%). The use of herbal supplements increased among women who consider themselves as being overweight (p < 0.001). Furthermore, herbal dietary interventions decreased with more frequent attempts for a weight-loss diet (p < 0.001).

Originality/value

To the best of the authors’ knowledge, this study represents a first attempt at assessing the use of herbal dietary supplements for weight loss among regularly exercising Turkish women. With the increase of body mass index and body perception being as overweight, herbal dietary interventions were also increased. In particular, women with obesity (61.9%) used more herbal dietary interventions than women with healthy weight (37.5%). Moreover, women with an overweight body perception used more herbal supplements than those who thought they had a healthy body weight.

Abstract

Purpose

The purpose of this study is to investigate food supplement intake among gym-goers.

Design/methodology/approach

A cross-sectional study, using a validated questionnaire, was conducted. All participants were gym-goers who voluntarily enrolled from eight selected gyms in Perugia. A multivariate regression analysis was performed.

Findings

In our sample, 44.9per cent (n = 57) of participants consumed dietary supplements, at least once a week, with no association with sex (p = 0.5) and educational level (p = 0.4). Supplements intake was statistically significant and associated with very low intake of mineral water (p = 0.01), diet specific for fitness programmes (p < 0.01), information about nutrition from personal trainers (p < 0.01), frequency of physical activity (p = 0.01), society’s attention to nutrition (p = 0.04) and marginally with frequency of weigh control (p = 0.05).

Originality/value

Food supplements intake seems to be extensively used among gym-goers, and it seems related to information about nutrition from personal trainers. However, specialized personnel, such as dietitian or nutritionist, should supervise supplements intake.

Abstract

Purpose

The purpose of this paper is to identify the demographic and psychographic characteristics of older green tea consumers in the USA. By understanding this segment’s background, perceptions, and behaviors, health and marketing professionals can tailor messages to reach clients and consumers.

Design/methodology/approach

An online survey was completed in January 2014 with 1,335 older adult consumers (=55 years old). Data were analyzed using descriptive statistics and binomial logistic regression.

Findings

More than half (n=682, 51.2 percent) of respondents drank green tea. Most green tea consumers in this sample are college-educated and employed female home owners. The odds for green tea consumption are greater if a respondent is in good health, was informed about diet and health, or made a health-related dietary change in the past year. There are greater odds of consumption if the respondent is familiar with the relationship between drinking green tea and the reduced risk of cancer however, the importance of health statements on product labels are not predictive of consumption.

Research limitations/implications

This study was conducted in the USA and with older adults. Future research should explore characteristics of younger consumers, i.e. 18-54 years old.

Practical implications

Health educators, regulators, and marketing professionals may use this profile to tailor messages that speak to consumers and client’s values and motivations.

Originality/value

To the authors’ knowledge, this is the first profile of older adult green tea consumers in the USA.

Abstract

Purpose

The purpose of this paper is to analyse differences in sociodemographic and sporting characteristics, health-behaviours, and food intake of athletes using and not using nutritional supplements (NS).

Design/methodology/approach

High-performance Portuguese athletes from 13 sports completed a NS usage questionnaire, assessing information on sociodemographic (sex, age, height, weight, athlete’s, and parental education level), health-related (smoking, daily time of sleeping, walking, and sitting), and sporting (type, number of international performances, weekly hours of training and weekly hours of gym) characteristics; and a semi-quantitative food-frequency questionnaire (86 items), regarding the previous 12 months.

Findings

From the 241 athletes (66 per cent males, 13-37 years), 64 per cent reported NS use. Supplement usage was associated with age 18 years (odds ratio (OR) 2.57, 95 per cent; confidence interval (CI) 1.17-5.65), performing individual sports (OR 5.45, 95 per cent; CI 2.49-11.93) and > 2 h gym/week (OR 2.42, 95 per cent; CI 1.15-5.11), a higher consumption of meat (OR 2.83, 95 per cent; CI 1.36-5.90), eggs (OR 2.53, 95 per cent; CI 1.07-5.96), and yogurt (OR 2.24, 95 per cent; CI 1.08-4.62), and a lower intake of processed meat (OR 0.32, 95 per cent; CI 0.15-0.72), vegetable oils (OR 0.35, 95 per cent; CI 0.17-0.74), margarine (OR 0.37, 95 per cent; CI 0.18-0.76), chips (OR 0.22, 95 per cent; CI 0.10-0.48), and fast food (OR 0.42, 95 per cent; CI 0.19-0.91).

Originality/value

Athletes using NS had different characteristics from non-users, and seemed to have healthier and more sports-oriented food choices. Our findings may help sport and health professionals to identify an alleged or future NS user, enabling the development of a timely and self-directed supplement scheme.

Abstract

Purpose

The deficiency or excess of serum zinc in pregnancy may threaten the health of the mother and the fetus. The purpose of this study is to determine the pattern of serum zinc in pregnant women covered by Urmia urban health centers and its association with some nutritional and clinical determinants in the third trimester, from July to December 2018.

Design/methodology/approach

In this analytic cross-sectional study, of six selected health centers in Urmia, 400 pregnant women subjects who were in their third trimester were recruited in a simple random manner. The nutritional, demographic, clinical data as well as fasting blood samples were taken from each of the subjects. The data were analyzed using chi-square, independent t-test and logistic regression tests.

Findings

The study revealed that about 3 per cent of pregnant women had zinc deficiency, 70.2 per cent were normal and 26.8 per cent had high serum zinc levels. In 388 pregnant women (72.4 per cent with normal serum zinc and 27.6 per cent with high serum zinc), binary logistic regression model showed that high concentration of serum zinc was directly associated with dietary intake zinc (OR: 2.252; 95 per cent CI: 1.85-2.74), supplement zinc (OR: 7.823; 95 per cent CI: 3.676-16.649) and total intake magnesium (OR: 1.005; 95 per cent CI: 1.000-1.01) and inversely associated with frequent reproductive cycling (OR: 0.739; 95 per cent CI: 0.569-0.959).

Originality/value

Pregnant women in Urmia probably have high concentrations of serum zinc, and it is likely related to consumption of the zinc supplementation. Supplementation programs need to be scaled up for pregnant women that take inadequate dietary zinc.

Abstract

Purpose

The paper investigates the role of social networks in the millennials’ decision-making process of illegal and unnotified food supplements purchase. The connections and interactions that (co) produce information are studied with a holistic perspective of social sustainability as a development driver of business model innovation.

Design/methodology/approach

An exploratory qualitative multiple analysis study was conducted in two consecutive phases. Data from 23 semi-structured individual interviews were collected, followed by a netnographic analysis of the Facebook virtual community.

Findings

The results show that the decision-making process does not develop following the traditional sequence, as social networks modify the wellness meaning creation process and reduce risk perception. Moreover, social networks introduce the use of similar experiences of others and online information and emotional support on unethical and unhealthy behavior.

Research limitations/implications

Due to the application to a social network, the results should be understood within this context. Future studies would benefit by expanding the target and the range of social networks explored.

Practical implications

The official information quality control, as a prerogative of public and professional health stakeholders, and the medialization of medicalization, contribute to the conscious development of their wellness meanings and values.

Originality/value

This work represents one of the first attempts to investigate resources integration through social networks in the pre-purchase decision-making process of unnotified and illegal food supplements. Unethical and unhealthy behavior develops through the interaction of actors, firms, influencers and individuals over social networks.

Abstract

The aim of this study was to examine the demographic, health habits and personal values associations of white bread use. A total of 474 randomly selected consumers completed a questionnaire about bread consumption, health habits and personal values. The findings showed that compared with non‐consumers white bread users were younger, less educated, more likely to have children and to be smokers. They were less likely to follow vegetarian, low fat or special diets or use alternative therapies. Non‐consumers were more likely to hold pro‐nature universalistic values. This suggests that the use of this staple food is associated with demographic, behavioural and ideological domains. Their causal inter‐relationships require further investigation.

Abstract

Purpose

The purpose of this research is to trace the evolution of the claims used for advertising food products in Italian magazines, by analysing the content and structure of the claims, the target audiences and the elements that have the greatest influence on the presence of the claims in food advertising.

Design/methodology/approach

On the basis of the research conducted by Pratt and Pratt (1995), revised and adapted to the Italian food context, the authors designed a matrix of 1,316 advertisements, which were selected based on the analysis of 67,340 advertisements and using the reference to the food sector as a discriminator. The advertisements were extrapolated from a sample of six Italian magazines, so as to determine the extent to which the various demographic groups in Italy are exposed to print advertising for food, beverages and food supplements. The authors examined the frequency of the relevant advertising forms over a period of four years, from January 2014 to December 2017.

Findings

The results revealed the main types of claims used in the four-year period, as well as the statistically significant differences between the different magazine panels, as concerns the frequency and the types of messages. Moreover, a strong relationship between the number of advertisements in the magazines and the time of the year was also ascertained, as well as significant gender variations.

Originality/value

This study introduces the trends and dynamics of the Italian printed advertising for food to the relevant scientific literature. The results yielded by this research have added further implications and contributions to the existing studies, as concerns claim diffusion based on type, gender and seasonality, and the authors also provide important insights to various socio-economical stakeholders.
