Bankole E, Harris N, Rutherford S, Wiseman N. Nigerian adolescents' exposure to fast food marketing via Instagram. BMC Public Health 2024; 24:2405. [PMID: 39232697 PMCID: PMC11376060 DOI: 10.1186/s12889-024-18604-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Accepted: 04/15/2024] [Indexed: 09/06/2024] Open
Abstract
OBJECTIVES To explore the promotion of fast food to lower-income adolescents on Instagram with the specific aims of (i) identifying the marketing strategies used by fast food brands on Instagram to promote fast food to Nigerian adolescents and (ii) examining the influence of these strategies on user engagement. DESIGN A content analysis of posts from a 90-day period of the Instagram accounts of five fast-food brands in Nigeria was conducted. Overall, 576 posts were analysed, using a codebook developed based on the relevant literature, to identify adolescent-targeted strategies. User engagement was measured by number of likes each post received. RESULTS The observed brands frequently utilised adolescent-targeted marketing strategies, with the most popular strategies being emotional appeal, 'teen language' and product appeal. The results of Mann-Whitney U tests revealed significant associations between the use of these promotional strategies and user engagement. Adolescent-aimed strategies like product appeal and competitions resulted in higher user engagement with fast food promotional content. CONCLUSION Fast food companies heavily target lower income adolescents through the use of Instagram. This raises health concerns related to the consumption of unhealthy food that arises from regular advertising in that demographic. Further, this exposure increases ad interactions that could cause adolescents to view fast foods more positively. Overall, findings indicate the need for actions aiming to limit and reduce the effect of adolescents' exposure to fast food marketing on social media, to target the features of social media platforms which affords users the ability to interact with fast food advertisements.

Kadel P, Heist N, Paulheim H, Mata J. From Pixels to Palate: Communication around #vegan on Instagram and its relation with eating intentions. Appetite 2024; 200:107518. [PMID: 38801997 DOI: 10.1016/j.appet.2024.107518] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Revised: 04/26/2024] [Accepted: 05/23/2024] [Indexed: 05/29/2024]
Abstract
Social media is an increasingly important yet understudied context for eating behaviors in general and veganism in particular. In four studies, we first explored and described the information environment the platform Instagram presents related to veganism. Second, we examined how engaging with this environment is associated with offline eating intentions via psychological mechanisms. We scraped datasets of Instagram posts tagged with #vegan (44,316 posts in total) and employed network analysis with their hashtags (Study 1), as well as clustering with images and sentiment analysis with texts (Study 2). Studies 3 (N = 117) and 4 (N = 251) used online surveys to investigate associations between different forms of engaging with social media content, psychological constructs, and offline eating intentions. Posts about veganism were frequently related to food, health and fitness, cosmetics, and photography. Images most often depicted food (34.7%), non-food products (30.4%), people (7.9%), and animals (2.0%). The sentiment of most posts was positive. Being exposed to Instagram content about veganism was more strongly and consistently associated with eating intentions than active forms of engagement. Attitude and self-identity emerged as the most relevant mechanisms for these effects. Food is the most prominent yet not sole topic among posts about veganism on Instagram, and hashtags used in this context partially relate to motives for following a vegan diet. Exposure to this information environment might influence offline eating decisions via psychological mechanisms. With growing usage and its potential influence, social media should receive increasing attention in (health) psychological research and practice.

Abstract
OBJECTIVE Assess the acceptability of a digital grocery shopping assistant among rural women with low income. DESIGN Simulated shopping experience, semistructured interviews, and a choice experiment. SETTING Rural central North Carolina Special Supplemental Nutrition Program for Women, Infants, and Children clinic. PARTICIPANTS Thirty adults (aged ≥18 years) recruited from a Special Supplemental Nutrition Program for Women, Infants, and Children clinic. PHENOMENON OF INTEREST A simulated grocery shopping experience with the Retail Online Shopping Assistant (ROSA) and mixed-methods feedback on the experience. ANALYSIS Deductive and inductive qualitative content analysis to independently code and identify themes and patterns among interview responses and quantitative analysis of simulated shopping experience and choice experiment. RESULTS Most participants liked ROSA (28/30, 93%) and found it helpful and likely to change their purchase across various food categories and at checkout. Retail Online Shopping Assistant's reminders and suggestions could reduce less healthy shopping habits and diversify food options. Participants desired dynamic suggestions and help with various health conditions. Participants preferred a racially inclusive, approachable, cartoon-like, and clinically dressed character. CONCLUSIONS AND IMPLICATIONS This formative study suggests ROSA could be a beneficial tool for facilitating healthy online grocery shopping among rural shoppers. Future research should investigate the impact of ROSA on dietary behaviors further.

Social capital and healthy eating among two ethnic minority groups in Yunnan Province, Southwest China: the mediating role of social support and nutrition knowledge. Front Nutr 2024; 11:1273851. [PMID: 38883859 PMCID: PMC11176612 DOI: 10.3389/fnut.2024.1273851] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Accepted: 05/23/2024] [Indexed: 06/18/2024] Open
Abstract
Background Although social capital has been linked to dietary intake particularly in disadvantaged populations, little is known about the mechanisms. This study aimed to investigate whether social support (SS) and nutrition knowledge (NK) mediate the association between social capital and healthy eating habits. Methods A probability sample of two ethnic minority groups in Yunnan Province, Southwest China were included (n = 1,033, mean age 47.5 ± 14.7 years). Bonding and bridging social capital (BOC and BRC) were assessed with the Personal Social Capital Scale (PSCS-16). Dietary data were evaluated with the Chinese Healthy Eating Index (CHEI), a measure of diet quality which reflects adherence to the Chinese Dietary Guidelines. NK and SS were measured with a validated questionnaire and scale, respectively. Structural Equation Modeling was used to calculate the direct, indirect and total effects of social capital on CHEI scores. Results The mean score of CHEI was 57.4 ± 9.8, which was significantly lower in men and older people. Low adherence to dietary guidelines were to observed in the consumption of dairy, beans, nuts, animal-source food vegetables and fruits. BOC and BRC were positively associated with CHEI score (β = 0.37 and 0.38, all p < 0.05). Social support and nutrition knowledge mediated 45.9 and 39.5% of the total effect of social capital on CHEI score, respectively. Conclusion Social capital appears to enhance adherence to dietary guidelines by improving nutrition knowledge and social support. Nutrition promotion programs therefore should consider incorporating strategies that foster social capital development, particularly in disadvantaged populations.

Current Status and Influencing Factors of Eating Behavior in Residents at the Age of 18~60: A Cross-Sectional Study in China. Nutrients 2022; 14:nu14132585. [PMID: 35807764 PMCID: PMC9268282 DOI: 10.3390/nu14132585] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 06/15/2022] [Accepted: 06/15/2022] [Indexed: 02/04/2023] Open
Abstract
As eating behavior is important to health, this cross-sectional study was conducted to analyze the factors influencing the eating behavior related to overweight and obesity of Chinese residents aged 18~60 based on the Ecological Model of Health Behavior. The short-form of the Eating Behavior Scale (EBS-SF) was applied to evaluate eating behavior. The multivariable linear stepwise regression analysis was used to identify and analyze the influence factors, and the receiver operating characteristic curves analysis to validate the predictive capability of the EBS-SF score in differentiating overweight and obesity. A total of 8623 participants were enrolled. In the personal characteristics, male (β = −0.03), older [36–45 years (β = −0.06) or 46–60 years (β = −0.07)], higher scores of Agreeableness (β = −0.04), Conscientiousness (β = −0.14) or Openness (β = −0.03) contributed to healthy eating behavior. In the individual behaviors, those who smoked (β = 0.04), drank alcohol (β = 0.05), exercised frequently (β = 0.07), had higher PHQ-9 scores (β = 0.29) may have improper eating habits. As for the interpersonal networks, the residents who were married (β = −0.04) behaved well when eating, while those who had offspring or siblings tended to have unhealthy eating behavior. At the community level, living in Western China (β = −0.03), having a monthly household income of 6001–9000 yuan per capita (β = −0.04), having no debt (β = −0.02), being retired (β = −0.03), or having lower PSSS scores (β = −0.03) led to lower EBS-SF scores. And the EBS-SF score demonstrated a moderate-high accuracy in predicting overweight and obesity.

Abstract
The need for adherence to a healthy and sustainable dietary pattern in the pediatric stage is discussed worldwide, being linked to a progressive incidence of noncommunicable diseases in adulthood. The aims of this systematic review were to summarize the healthy and/or sustainable dietary patterns, defined a priori, described in the literature for use during the pediatric stage; to evaluate the adherence to these dietary patterns; and identify the health-related benefits associated with adherence to these patterns. A literature search was carried out on Medline, Scopus, and Web of Science from 2010 up to 2021, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 128 articles were included according to the following criteria: participants 2-17 y old, healthy and/or sustainable dietary patterns defined by an a priori methodology; articles written in English or Portuguese; and published since 2010. Fifty instruments with 14 adaptations that measure adherence to healthy and/or sustainable dietary patterns in children and adolescents were found. The Mediterranean Diet was the most studied dietary pattern. Adherence to healthy and/or sustainable dietary patterns has wide variations worldwide. Most of the instruments described have been little studied at pediatric ages, reducing the ability to extrapolate results. Higher adherence to these dietary patterns was associated with lower body fat, waist circumference, blood pressure, and metabolic risk. There is no consensus regarding the association with BMI. No studies have proofs of the sustainability characteristics of these instruments, it being necessary to produce a new sustainable instrument or test the association of the previous ones with, for example, the ecological footprint. Further validations of these instruments in each country and more prospective studies are needed to establish temporal relations with health-related outcomes. This systematic review was registered at www.crd.york.ac.uk/prospero/ as CRD42020221788.

Abstract
Background Social support is an important health determinant and may affect dietary behaviors. The purpose of this study was to examine the relations between perceived social support and the Chinese Diet Balance Index-16 (DBI-16) among ethnic minority groups in Southwest China. Methods This cross-sectional study was conducted between May 2019 and August 2020 among six ethnic minority groups native to Yunnan Province (n = 3564). Perceived social support from family, friends and significant others were measured with the Multi-dimensional Scale of Perceived Social Support (MSPSS). Dietary data were obtained using a 100-item Food Frequency Questionnaire (FFQ) and a lifestyle questionnaire. Lower Bound Score (LBS), Higher Bound Score (HBS) and Diet Quality Distance (DQD) which represent inadequate, excessive and unbalanced food intake respectively were calculated to measure the compliance with the recommendations of the Dietary Guidelines for Chinese 2016. Results One thousand four hundred ninety-six men and two thousand sixty-eight women were included. 51.2% of the subjects had moderate or high levels of inadequate intake; 21.3% had moderate or high levels of excessive intake; and 74.0% had moderate or high levels of unbalanced dietary intake. With potential confounders adjusted, support from family was negatively associated with inadequate intake, while support from friends was positively associated with inadequate and excessive intake. No significant associations were found between perceived social support from significant others and diet quality indicators. Conclusions An unbalanced diet is common among adults of the ethnic minority groups in Yunnan Province, Southwest China. Social support should be taken into account in designing nutrition interventions rather than focusing solely on individuals.

Abstract
OBJECTIVES The aims of this study were to examine the associations between perceived social support and oral health behaviors among adolescents and if this perception had a protective effect against the influence of perceived racial discrimination on oral health behaviors in this population. MATERIAL AND METHODS Participants of this cross-sectional study were adolescents aged 12-18 years recruited from University dental clinic. They completed a questionnaire comprising three sections: demographics (14 items), oral health behaviors (6 items), and validated Personal Resource Questionnaire (25 items). Perceived discrimination was evaluated by a question asking if the adolescent had ever experienced discrimination based on their race. RESULTS Of 252 participants, mean (SD) age of 14 (1.8) years, 60% were girls, 56% were self-identified as White, and 81% were born in Canada. Discrimination was reported by 21%. Frequency of toothbrushing and self-rated oral health were significantly associated with increased levels of perceived social support. Sugar consumption was significantly different for participants with and without perceived racial discrimination (p-value = 0.002). Perceived social support did not act as a buffer against perceived racial discrimination for sugar consumption (OR = 1.00; 95% CI: 0.98-1.01). CONCLUSIONS Adolescents' perceived social support affected some aspects of their oral health but did not moderate the influence of perceived racial discrimination.

Abstract
BACKGROUND The rising childhood obesity rate is a major public health challenge. The objective of this study is to examine key underlying mechanisms for peer-related social influence on preadolescents' healthy eating behavior by including factors closely linked with the quality of preadolescents' relationship with peers. METHODS A cross-sectional study was conducted in a convenience sample of 278 Lithuanian preadolescents, recruited from a public school. A questionnaire containing sociodemographic questions, questions about food intake, peer-related social norms of healthy eating, social self-efficacy, vegetable preference, need for peer approval and feeling of belonging were applied. Data was analyzed using structural equation modeling. RESULTS The results of the SEM showed that social self-efficacy predicts feeling of belonging to the peer group and need for peer approval. Feeling of belonging and need for peer approval predict actual intake of vegetables via injunctive norms of healthy eating. However, neither feeling of belonging nor need for peer approval predicted descriptive norms of healthy eating. Contrary to our expectations, descriptive norms were found to be unrelated with actual intake of vegetables, though vegetable preference predicted actual intake of vegetables. Vegetable preference was not predicted by injunctive or descriptive peers' social norms of healthy eating. CONCLUSIONS The findings of this study offer insight for informing parents, teachers and for social norms marketing interventions by stressing the importance of social relations when the aim is to encourage healthy eating among preadolescents.

Abstract
Obesity is a multifaceted chronic condition with several contributing causes, including biological risk factors, socioeconomic status, health literacy, and numerous environmental influences. Of particular concern are the increasing rates of obesity in children and adolescents, as rates of obesity in youth in the United States have tripled within the last three decades. Youth from historically disadvantaged backgrounds tend to have higher rates of obesity compared to other groups. Adolescents often do not meet intake recommendations for certain food groups and nutrients, which may contribute to a heightened risk of obesity. With obesity disproportionately affecting adolescents (ages 12–19 years), negative effects of excess adiposity may be particularly salient during this critical period of development. The presentation of chronic cardiometabolic disease symptoms typically observed in adults, such as hypertension, hyperglycemia, dyslipidemia, and inflammation, are becoming increasingly common in adolescents with obesity. Additionally, there is dynamic interplay between obesity and psychosocial health, as adolescents with obesity may have increased levels of stress, depressive symptoms, and reduced resilience. To reduce and prevent adolescent obesity, the implementation of theory-driven multicomponent school- and community-based interventions have been suggested. These interventions promote knowledge and self-efficacy for healthful practices that have the potential to progress to sustained behavior change.

Abstract
Background. The health impact of youth mentors serving in the delivery of child nutrition and physical activity (PA) interventions on youth mentors themselves has been understudied. Objective. The primary objective of the current study was to examine the impact of engaging youth mentors in the delivery of a summertime childhood obesity prevention intervention on youth mentors' behavioral health. Method. Data were collected at baseline and postintervention. A survey of validated nutrition, mental health, PA, and psychosocial questionnaires was administered. Diet was assessed via 24-hour recall. Height, weight, and waist circumference (WC) were measured. In-depth interviews were conducted with youth mentors. Results. Eleven youth mentors enrolled: 60% were female, mean age was 16.1 ± 0.38 years, and 100% were Black. Mean kilocalories (p = .05), sugar-sweetened beverage intake (p = .08), and waist circumference (p = .04) decreased. In-depth interviews were conducted with 11 youth mentors, and three themes emerged: perceived improvement in nutrition, PA, and mental health-related behaviors; formation of a positive role modeling relationship with the child campers; and strengthening of higher education goals and future career aspirations. Conclusions. Youth mentor staffing may be an important intervention strategy for changing health behaviors among youth mentors. Results from this study can be used to inform utilization of youth mentors in the delivery of this and similar health behavior interventions in the future.

Abstract
OBJECTIVE Evaluate the feasibility, fidelity and preliminary efficacy of Camp NERF to prevent unhealthy weight gain and promote healthy behaviours in children during the summer. DESIGN Camp NERF was an 8-week, multicomponent, theory-based programme coupled with the US Department of Agriculture's Summer Food Service Program. Twelve eligible elementary-school sites were randomized to one of three treatment groups: (i) Active Control (non-nutrition, -physical activity (PA), -mental health); (ii) Standard Care (nutrition and PA); or (iii) Enhanced Care (nutrition and PA, plus cognitive behavioural techniques) programming. Efficacy was determined by assessing mean change by group in child outcomes using hierarchical linear regression models. SETTING Low-income, urban neighbourhoods in Columbus, OH, USA.ParticipantsEconomically disadvantaged, racial minority children of elementary school age (kindergarten-5th grade). RESULTS Eighty-seven child-caregiver dyads consented; eighty-one completed pre- and post-intervention assessments resulting in a 93·10 % retention rate. Delivery of the intended lesson occurred 79-90 % of the time. Of the children, 56·98 % (n 49) were female; 89·53 % (n 77) were Black. Overall mean change in BMI Z-score from baseline to post-intervention was -0·03 (se 0·05); change in BMI Z-score did not differ significantly between treatment group. Change in nutrition, PA, mental health or psychosocial outcomes did not differ between groups. CONCLUSIONS Results from the current study demonstrate feasibility and fidelity, yet no intervention effect of Camp NERF. Instead, findings suggest that participation in structured programming of any type (health behaviour-related or not) may prevent unhealthy summer weight gain. Additional studies are needed to confirm findings. Results have implications for child nutrition policy addressing the issue of summer health.

Similar Mediterranean diet adherence but greater central adiposity is observed among Greek diaspora adolescents living in Istanbul, compared to Athens. ETHNICITY & HEALTH 2018; 23:221-232.

Abstract
OBJECTIVE The aim of this case-control study was to compare Mediterranean diet (MD) adherence and anthropometry between Greek diaspora adolescents living in Istanbul and Greek adolescents, inhabitants of Athens. DESIGN A total of 206 adolescents (103 from each site), aged 10.0-19.0 years old, all of Greek origin, were recruited from schools in Athens and minority schools in Istanbul, for the present case-control study. Participants at each site were age and sex-matched. Anthropometric measurements were performed, and diet adherence was assessed with the KIDMED score. RESULTS Breakfast skipping, decreased dairy and increased commercially baked good/pastries consumption for breakfast, fast-food intake and consumption of several sweets each day was more prevalent in Istanbul, but, on the other hand, students from Athens reported eating fewer fruit, vegetables and nuts. The adoption of unhealthy eating habits in each site was counterbalanced by a more 'healthy' dietary element, resulting in an overall similar MD adherence between both sites. Additionally, although weight status was indifferent between the two cities, higher rates of abdominal obesity were recorded in Istanbul, when the weight-to-height ratio was used for diagnosis. CONCLUSIONS Differences in several domains of the KIDMED score were recorded among cities, possibly as results of food availability and prices. However, MD adherence and weight status appeared similar, indicating that the dietary transition and acculturation experienced by the remnants is actually very slow and minimal during the 93 years since population exchange.

Abstract
BACKGROUND Although many people intend to eat healthily, they often fail to do so. We report the first randomised trial testing whether smartphone-based support groups can enhance healthy eating. METHODS Adults (N = 203) were randomised to the support or control condition (information), and to one of two eating goals (increasing fruit and vegetable/decreasing unhealthy snack consumption). After baseline, participants received information on their assigned eating goal, and completed a 13-day electronic diary. During Days 4-10, support participants were asked to support each other in achieving their eating goal in smartphone-based groups. The primary outcome was daily servings of fruit/vegetables or unhealthy snacks. Maintenance of intervention effects was assessed on Days 11-13, and at 1-month and 2-month follow-ups. RESULTS Support participants showed a gradual increase in healthy eating over time, and ate 1.4 fruits and vegetables more, 95% CI [0.3, 2.6], or 0.8 unhealthy snacks less, 95% CI [-1.4, -0.2] than controls on Day 10. Most effects were not maintained at follow-ups. CONCLUSIONS Smartphone-based groups can promote fruit and vegetable consumption and decrease unhealthy snack intake. This study extends previous findings of the benefits of support groups, and sheds light on the temporal dynamics of behavior change.

Household, psychosocial, and individual-level factors associated with fruit, vegetable, and fiber intake among low-income urban African American youth. BMC Public Health 2016; 16:872. [PMID: 27558162 PMCID: PMC4997673 DOI: 10.1186/s12889-016-3499-6] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2015] [Accepted: 08/12/2016] [Indexed: 01/12/2023] Open
Abstract
BACKGROUND Childhood obesity, one of the greatest challenges to public health, disproportionately affects low-income urban minority populations. Fruits and vegetables (FV) are nutrient dense foods that may be inversely associated with excessive weight gain. We aimed to identify the individual characteristic, psychosocial, and household factors influencing FV and fiber consumption in low-income African-American (AA) youth in Baltimore, MD. METHODS Cross-sectional analysis of data collected from 285 low-income AA caregiver-youth (age range: 10-14 y) dyads participating in the baseline evaluation of the B'More Healthy Communities for Kids obesity prevention trial. The Kid's Block FFQ was used to estimate daily intakes of FV (including 100 % fruit juice) and dietary fiber. Questionnaires were used to assess household socio-demographics, caregiver and youth food purchasing and preparation behavior, and youth psychosocial information. Ordered logit regression analyses were conducted to examine psychosocial and food-related behavior associated with FV and dietary fiber intake (quartile of intake) controlling for youth age, sex, BMI percentile, total calorie intake and household income. RESULTS On average, youth consumed 1.5 ± 1.1 (M ± SD) servings of fruit, 1.8 ± 1.7 serving of vegetables, and 15.3 ± 10.9 g of fiber/day. There were no differences by gender, age or household income. Greater youth's healthy eating intentions and self-efficacy scores were associated with greater odds ratio for higher intake of FV and fiber (Intention: ORfruit 1.22; 95 % CI: 1.06-1.41, ORvegetable 1.31; 1.15-1.51 and ORfiber 1.46; 1.23-1.74, Self-efficacy: ORfruit 1.07; 1.03-1.12, ORvegetable 1.04; 1.01-1.09, ORfiber 1.10; 1.04-1.16). Youth receiving free/low-cost breakfast were more than twice as likely to have higher fiber intake than those who did not receive free breakfast (OR 2.7; 1.10; 6.9). In addition, youth shopping more frequently at supermarkets were more likely to have greater vegetable and fiber intake (OR 1.26; 1.06-1.50; OR 1.28; 1.03-1.58, respectively). Also, youth with parents who shopped more frequently at fast-food stores had 7 % lower odds for higher vegetable intake (95 % CI: 0.88-0.99). CONCLUSION In this study, both, youth and household factors were associated with youth FV and fiber intake, underscoring the need for a multi-level approach to increasing youths' diet quality. These results will inform and shape an effective intervention program for improving youth dietary intakes.
