Abstract

Purpose

This study aims to examine the effects of character body size, subject body size and product type on female adolescents’ attitudes toward the character. Given prior research showing that adolescents identify more strongly with those whom they view as similar to themselves, it is possible that heavy and obese adolescents will react more favorably to plus-size ad characters.

Design/methodology/approach

Two studies were conducted, one with females aged 12–14 and a second with females aged 15–17. Based on their body mass index, subjects were classified as of small/average size or overweight/obese. Ads featured either a thin, average-size or plus-size character, and promoted either a healthful or an unhealthful snack item.

Findings

In general, small/average size female adolescents responded more favorably toward thin characters, whereas their overweight/obese counterparts responded more favorably toward plus-size characters. Moreover, subjects’ responses were not moderated by the nutritional value (healthful vs unhealthful) of the product being advertised.

Research limitations/implications

To effectively promote healthy foods to overweight/obese adolescents, it may be advantageous to incorporate plus-size characters. Additional research is needed, however, to determine whether this approach can effectively influence brand attitudes and consumption behaviors.

Social implications

As obesity rates continue to rise, it has become vitally important to encourage healthier food choices among youth. To develop effective communication strategies, marketers need to better understand how young consumers respond to various advertising cues.

Originality/value

To the best of the authors’ knowledge, this is the first study to examine the effect of character size and subject size on female adolescents’ attitudes toward the character.

Abstract

Purpose

Background/Objectives: Protein-based meal replacements (MR) with viscous soluble fibre are known aids for weight loss. This study aims to compare the effects of new whey and vegan MR containing different amounts of PGX (PolyGlycopleX) on weight loss over 12 weeks, along with a calorie-restricted diet.

Design/methodology/approach

Subjects/Methods: Sixty-eight healthy adults of both sexes (53 women; 15 men; average age 47.1 years; BMI 31 ± 7.1 kg/m2 and weight 85.05 ± 23.3 kg) were recruited. Participants consumed a whey or vegan MR twice/d (5–10 g/day PGX) with a low-energy diet (1,200 kcal/day), over 12 weeks. Weight, height, waist and hip circumference were recorded (four time periods).

Findings

Results: Forty-four participants completed the study. Results showed significant reductions in average body weight and at week 12, whey group was [−7.7 kg ± 0.9 (8.3%), p < 0.001] and vegan group was [−4.5 kg ± 0.8 (6.2%), p < 0.001)]. All participants (n = 44; BMI 27 to 33 kg/m2) achieved significant reductions in body measurements from baseline to week 12; p < 0.001. Conclusions: Supplementation of protein-based MR with PGX and a balanced, low-energy diet, appears to be an effective approach for short-term weight loss.

Research limitations/implications

As the authors were evaluating if the MR as a whole (i.e. with PGX) caused weight loss from baseline over the 12 weeks, no comparators, i.e. just the MR without PGX, were used. Formulation of these new MRs resulted in a whey product with 5 g PGX and a vegan product with 2.5 g PGX. Only 2.5 g PGX could be formulated with the vegan protein due to taste and viscosity limitations. Study participants were not randomized and no control groups (e.g. no MR or MR without PGX but with energy restricted diet) were used. Furthermore, it is not clear whether the sort of protein alone or the combination with a higher amount of PGX (whey with 5 g PGX/serving vs vegan with 2.5 g PGX/serving) has contributed to these significant greater weight-loss effects. This was something the authors were testing, i.e. could only 2.5 g PGX/serving have an effect on weight loss for a vegan MR. These limitations would be somethings to evaluate in a subsequent randomized controlled study. Hence, the results of this study may serve as a good starting point for further sophisticated randomized controlled trials that can demonstrate causality – which the authors acknowledge as one of the fundamental limitations of an observational study design. Participants tracked their calories but adherence and compliance were self-assessed and they were encouraged to keep their exercise routine consistent throughout the study. Hence, these are further limitations. No control group was used in this study to observe the effect of the dietary intervention and/or physical activity on weight loss alone. However, a goal of the authors was to keep this study as close to a real-life situation as possible, where people would not be doing any of these measurements, to see if with minimal supervision or intervention, people can still lose weight and alter their body composition. Furthermore, differences in gender and the corresponding weight loss effects in response to MR-protein-based treatments could be evaluated in follow-up studies.

Practical implications

This study indicates that the consumption of protein-based (animal, whey or plant, pea protein) MR incorporating the highly soluble viscous PGX is beneficial for weight loss when combined with a healthy-balanced, calorie-restricted diet. MRs at either 2.5 g or 5 g per serving (RealEasyTM with PGX) proved to be a highly effective as a short-term solution for weight loss. The observed results are encouraging, however, further long-term studies (i.e. randomized clinical trials RCT) are needed to confirm the clinical relevance. RCTs should focus on the individual effects of PGX and/or the different protein sources used in MRs, on weight loss and the maintenance of the reduced body weight, and should measure detailed blood parameters (lipid profiles, glucose etc.) as well as collect detailed exercise and food consumption diaries.

Originality/value

To the authors’ knowledge, this is the first study comparing a whey versus vegan, (as pea) protein-based MR that is supplemented with fibre PGX; thus, this work adds information to the already existing literature on fibre (such as PGX) and MRs regarding their combined weight loss effects. The purpose of this study was to observe if the novel protein-based (either whey or vegan versions) MR RealEasyTM with PGX at 2.5 or 5 g in addition to a calorie-restricted diet (total of 1,200 kcal/day) would aid in weight loss in individuals over a 12-weeks period. Adding increasing amounts of whey protein and soluble fibre can help reduce subsequent ad libitum energy intake which could help adherence to energy restricted diets, but whether similar effects are seen with vegan protein is unclear – this study does aim to address this.

Abstract

Purpose

The health of people living in prisons (PLP) frequently remains marginalised in national development discourse, particularly in resource-constrained settings like Ghana. This study aims to determine the prevalence of cardiovascular disease (CVD) risk factors among PLP at a prison facility in the Northern Region of Ghana.

Design/methodology/approach

A cross-sectional study involving 134 male persons in prison, aged 18–79 years, was conducted to assess their dietary habits, tobacco use, alcohol consumption, sleep behaviour and physical activity practices. Serum lipid profile, fasting blood glucose (FBG), blood pressure (BP) and body mass indices of participants were also measured.

Findings

Almost half (48.1%) of the participants had abnormal lipid levels. Those with FBG in the diabetes range (= 7.0 mmol/l) constituted 3.9%, while 16.7% were in the impaired FBG range (6.1–6.9 mmol/l). Participants with BP within the pre-hypertension range were 54.5%. The majority of participants (92%) had a low daily intake of fruits and vegetables. Few participants were active smokers (5%) and alcohol users (2%). The average sleep duration at night among the participants was 5.54 ± 2.07 h. The majority (74%) of the participants were sedentary. About a quarter of the participants (24.6%) had overweight/obesity.

Originality/value

This study highlights the CVD risks among PLP. Findings suggest the need for targeted interventions, such as dietary and lifestyle modification strategies, regular physical activity and routine screening for diabetes, dyslipidaemia and hypertension. These interventions within the prison space could significantly improve the cardiovascular health of PLP in resource-limited settings.

Abstract

Purpose

The purpose of this study is to evaluate the relationship between weight status and food environments, peer influence and dietary intake among high-school students in Shiraz, Iran.

Design/methodology/approach

Applying a case-control design, 406 adolescents (n = 203 overweight or obese and n = 203 normal weight) aged 14–18 years were selected using a multistage cluster random sampling method. Demographic information, physical activity level and anthropometric indices were collected. Dietary intake was determined using a 147-item food frequency questionnaire. Food environment (home and out of home) and peer influence were determined by a validated questionnaire.

Findings

The type of food purchased using pocket money was different between adolescents with overweight or obesity and normal weight adolescents (p < 0.001). The out-of-home food environment score was not different between groups, but the home food environment score (p = 0.004) and the peer influence score (p = 0.001) were higher in normal weight adolescents. Adolescents with overweight or obesity consumed higher amounts of carbohydrate (p = 0.006) and lower amounts of protein (p = 0.01) and more sweet junk foods (p = 0.01), nonstarchy vegetables (p = 0.03) and fruits (p = 0.01) compared to the normal weight group.

Originality/value

Home food environment, peer influence, differences in macronutrient intake and dietary patterns may be contributing factors to adolescent weight status.

This study aims to examine the association between minimum dietary diversity (MDD) and the concurrence of stunting and overweight (CSO) among children aged 6–23 months.

Abstract

Purpose

This study aims to examine the association between minimum dietary diversity (MDD) and the concurrence of stunting and overweight (CSO) among children aged 6–23 months.

Design/methodology/approach

A cross-sectional study was conducted in Sedayu Subdistrict, Bantul District, Daerah Istimewa Yogyakarta. The authors assessed the concurrence of stunting (height-for-age Z-score below −2 standard deviations SD) and overweight/obesity (Body mass index BMI-for-age Z-score above +2 SD) among a total of 189 children aged 6–23 months as the primary outcome. The authors defined MDD as consuming at least four out of seven food groups using a single 24-h recall. The authors also included other covariates, including sociodemographic characteristics, exclusive breastfeeding history and complementary feeding practices. To identify the factors associated with CSO, this study conducted multiple logistic regression across the study variables using STATA 16.1.

Findings

In the adjusted model, children who met the MDD criterion were associated with a reduced risk of CSO (adjusted odds ratios [OR]: 0.14; 95%confidence interval CI: 0.03–2.43). Compared to boys, girls were more likely to experience CSO (adjusted OR: 5.23; 95%CI: 1.02–26.9). Middle economic status was a protective factor for CSO (adjusted OR: 0.10; 95%CI: 0.01–0.98). This study did not find a significant relationship between CSO and the child’s age, low birth weight, exclusive breastfeeding, energy intake, protein intake, parental education and parental occupation.

Practical implications

This study suggests future programs and policies that promote dietary diversity to reduce the risk of CSO.

Originality/value

This study reveals the association between MDD and the coexistence of stunting and overweight.

Abstract

Purpose

This purpose of this study was to assess dietary diversity among women of reproductive age (WRA) and the associations between consumption of a diversified diet and overweight/obesity statuses in Ekiti State, Nigeria.

Design/methodology/approach

Cross-sectional study of 207 WRA from six local government areas in Ekiti State, Nigeria, was done. A validated interviewer-administered questionnaire was used to collect data on sociodemographic characteristics, dietary intake and anthropometry. Dietary intake was assessed with 24-h dietary recall to calculate the Minimum Dietary Diversity Score for Women (MDD-W). Data were analyzed using descriptive statistics, Spearman rank correlation and Chi square test at α0.05.

Findings

Majority of the participants (65.2%) were aged between 19 and 34 years, 58.5% were married and 49.8% had high school as their highest level of education. Mean MDD-W and body mass index (BMI) were 3.8 ± 0.9 and 25.46 ± 6.4 kg/m2, respectively. All participants (100%) consumed foods from the “grains, white roots and tubers” group and majority also from the “meat and poultry” group (79.7%) but ranked low in the consumption of foods from other food groups. Many were overweight (34.8%), obese (14.0%) and a few (1.9%) had morbid obesity. MDD-W was significantly associated with marital status (X2 = 7.7, P = 0.022) and BMI (X2 = 11.4, P = 0.023) and had a weak positive correlation with BMI (r = 0.189, P = 0.007).

Research limitations/implications

Study shows that both undernutrition and overweight/obesity coexist in the population, indicating a case of double burden of malnutrition (DBM) at a population level. However, further studies may be needed to investigate the extent of DBM at individual levels. Although there was a positive correlation between MDD-W and BMI, it cannot be used to predict causality. Study further reveals that the micronutrient intake of the WRA population in Ekiti is inadequate. Considering the importance of the 10 food groups highlighted in MDD_W to nutrition and health, the promotion of the consumption of foods from these food groups with more attention to the micronutrient-rich ones needs to be heightened.

Originality/value

Diet of participants was not diverse enough, indicating micronutrient inadequacy. Promotion of the consumption of a diverse diet, particularly from the food groups rich in micronutrient, needs to be heightened, while food groups high in calorie should be minimally consumed to forestall DBM.

Abstract

Purpose

The global rise in obesity can be closely linked to excessive calorie consumption and misperceptions regarding food intake. Thus, the purpose of this paper is to review the existing literature to have a better understanding how heuristic cues – mental shortcuts used for decision-making – impact calorie underestimation and consequently lead to unhealthy eating habits.

Design/methodology/approach

A search was conducted across multiple databases with priority given to studies in developed countries that provided insights into the cognitive processes behind food choices, the application of specific heuristics, and the association with eating behaviours. Articles were also selected based on their methodological quality.

Findings

The main findings are that the dichotomous categorization of foods as healthy or unhealthy can result in underestimating the calorie content in those foods perceived as healthy. Although nutrition claims, health claims and campaigns help in the fight against obesity, there is also the risk that consumers’ reliance on heuristic-based decision-making could aggravate the problem because a misinterpretation or misrepresentation could lead to calorie underestimation and overeating.

Practical implications

To establish effective behavioural interventions for obesity prevalence -, it is critical for interventions and policies to understand how consumers perceive calorie content and how they interpret claims on food marketing or packaging. Recognizing and addressing these heuristic-driven biases and understanding the factors influencing food choices are crucial for encouraging healthier eating habits.

Originality/value

To the best of the authors’ knowledge, this paper is the only review to date that consolidates research on the topic, drawing from multiple disciplines.

Abstract

Purpose

The purpose of this study is to collect and assess the evidence available on the effect of non nutritive sweeteners on appetite, weight and glycemic regulation. As a replacement for sugars, non-nutritive sweeteners (NNSs) are widely being used in different food products with the assumption that these would lower calorie intake and help to manage weight and blood sugar levels better. However, studies using animal models have reported that chronic exposure to NNSs leads to increased food consumption, weight gain and insulin resistance.

Design/methodology/approach

Evidence was acquired from systematic reviews or meta-analyses (2016–2021) of relevant clinical studies, especially randomized control trials using Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines.

Findings

The review showed NNSs exposure did not conclusively induce increased food intake or change in subjective appetite ratings. Appetite biomarkers like ghrelin, gastric inhibitory peptide, C-peptide levels and Peptide YY remained mostly unaffected by NNSs. Meta-analyses of human randomized control studies showed a reduced energy intake and body weight. No significant change was seen in blood glucose levels, post-prandial glycemic or insulin response after consumption of NNSs. Adequate evidence is not available to conclusively say that NNSs influence gut health at doses relevant to human use.

Research limitations/implications

Most studies which are prospective cohort, observational and cross-sectional studies suggest that use of NNSs may promote obesity and metabolic syndrome in adults. Such studies are plagued by confounding variables and reverse causation. Mechanistic evidence is mostly based on in-vitro and in-vivo studies. The same causal pathways may not be operative or relevant in humans.

Practical implications

This review of available literature concludes that to achieve specific public health and clinical goals, the safe use of NNSs for the reduction of intakes of free sugars and energy should be explored. This would be possible by educating the consumer about energy compensation and understanding the nutritional content of artificially sweetened products in terms of calories coming from fat and complex carbohydrates used in the product.

Originality/value

This study was, thus, designed with the objective of examining the usefulness of NNSs in human population, especially with respect to insulin regulation, glycemic control and weight management. Well-designed randomized control trials which control for confounding variables are needed to generate high quality evidence.

Abstract

Purpose

This study aims to assess the nutritional status and physical fitness status of school children among major ethnic and Dalit populations, in Rajshahi, Bangladesh.

Design/methodology/approach

Data were collected through structured questionnaires administered to mothers or caregivers of the children, followed by physical fitness assessments. Anthropometric indicators were used to evaluate nutritional status, including body mass index-for-age, height-for-age, and weight-for-height, based on Centre for Disease Control guidelines. Physical fitness was assessed through tests for flexibility, abdominal, muscular, speed, and lower limb strength. Statistical analysis was performed using SPSS.

Findings

Approximately 45% of boys and 55% of girls had normal nutritional status. However, the study also identified varying percentages of children with stunted, underweight, wasted, and mixed nutritional issues, highlighting the prevalence of malnutrition among this population. Boys consistently outperformed girls in terms of physical fitness across all age groups, with 84% to 90% of boys meeting established fitness criteria. Girls face a 1.8-fold and 2.2-fold increased risk of wasted and underweight conditions compared to boys. Lower-income group children exhibit a 2.6-fold and 1.6-fold increased risk of wasted conditions and underweight conditions. Children consuming meals twice a day have a 2.1-fold and 2.5-fold elevated risk of wasted and underweight conditions compared to others.

Originality/value

This study highlights the need for interventions and strategies to improve the nutritional and health status of ethnic children in Rajshahi, Bangladesh, considering their diverse dietary habits and lifestyles. By addressing these issues, the authors can empower these communities to actively contribute to the social and economic development of the region.

Abstract

Purpose

Nutrition labels provide a cost-effective method of conveying nutrition information to consumers. This study aimed to assess the use of nutrition facts panels, knowledge of traffic light labelling (TLL) and perceived healthiness of food items using TLL among consumers.

Design/methodology/approach

A web-based cross-sectional study was conducted among adults in the United Arab Emirates (UAE) (n = 1,322). TLL knowledge score was derived for each participant. Conjoint analysis was used to calculate the utilities and relative importance of the perceived healthiness scores for four attributes (fat, saturated fat, total sugar, salt) at the aggregate level.

Findings

Participants had a positive attitude towards TLL but were less familiar with TLL than the nutrition facts panel (47.4 vs 85.8%). The mean TLL knowledge score was 3.6 out of 7 (51.6%). Younger age, higher education, higher income, and health-related qualifications were associated with higher scores. Conjoint analysis showed that participants tend to choose products with greener labels, especially for sugars (80.1%) and avoid red labels for fats. Sugars had the highest percentage value of relative importance compared to the other attributes (27.1%).

Originality/value

The study outcomes offer valuable insights into the extent of consumer awareness, comprehension and utilization of nutrition facts panels in the UAE. These findings contribute essential knowledge for a deeper understanding of the impact of nutrition labels on consumer behaviour and decision-making in the region.
