Pandey S, Olsen A, Perez-Cueto FJA, Thomsen M. Nudging Toward Sustainable Food Consumption at University Canteens: A Systematic Review and Meta-Analysis. JOURNAL OF NUTRITION EDUCATION AND BEHAVIOR 2023; 55:894-904. [PMID: 37930295 DOI: 10.1016/j.jneb.2023.09.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 09/24/2023] [Accepted: 09/26/2023] [Indexed: 11/07/2023]
Abstract
INTRODUCTION This systematic literature review and meta-analysis investigated the effectiveness of the nudging approach toward sustainable food consumption in the university canteen context. METHODS The systematic literature search was carried out in 5 databases, Web of Science, PubMed, Scopus, ProQuest, and the Royal Library, identifying 14 eligible studies and selecting 9 articles containing adequate information for meta-analysis. The nudging strategies were classified using the typology of interventions in the proximal physical microenvironments framework that resulted in 5 different intervention types: availability, position, size, presentation, and information that belonged to either intervention class-altering properties or placement. RESULTS The study identified presentation, availability, and information as the most promising nudge intervention for achieving sustainable food consumption at the university canteen or similar settings. Nudging by altering the properties had a small effect size (d = 0.16), and nudging by altering placement showed a medium effect size (d = 0.21). DISCUSSION Nudging interventions implemented after understanding consumers' current behavior showed positive effectiveness toward sustainable food consumption rather than implementing random nudges. CONCLUSIONS AND IMPLICATIONS It is important that future studies aim to achieve sustainable food consumption by understanding canteen user food preferences and food choice motives before designing a nudging strategy.

Abstract
PURPOSE OF REVIEW Obesity is a growing public health concern worldwide, especially among young adults. This scoping review aims to identify and summarize the current evidence on dietary and lifestyle risk factors associated with obesity among young adults. RECENT FINDINGS A scoping review was performed using the PRISMA-ScR guidelines. A systematic search of five electronic databases published from inception to October 2023 was conducted. A total of 46 observational studies met the inclusion criteria and were included in the review. The findings suggest that high intake of energy-dense foods, unhealthy eating habits, poor sleep quality, and increased screen time were significant risk factors for obesity among young adults. In contrast, the association between obesity and sedentary behavior, low physical activity levels, alcohol consumption, and smoking habits was inconclusive. The reviewed evidence suggests that unhealthy dietary habits and lifestyle behaviors are associated with an increased risk of obesity among young adults. The findings highlight the need for further research on these modifiable risk factors to prevent and manage obesity among young adults.

Pandey S, Budhathoki M, Yadav DK. Psychosocial Determinants of Vegetable Intake Among Nepalese Young Adults: An Exploratory Survey. Front Nutr 2021; 8:688059. [PMID: 34179061 PMCID: PMC8222569 DOI: 10.3389/fnut.2021.688059] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Accepted: 05/18/2021] [Indexed: 11/13/2022] Open
Abstract
Background: Adequate intake of vegetables facilitates a healthy lifestyle. However, the majority of Nepalese young adults consume inadequate amount of vegetables per day. Objectives: We explored psychosocial determinants of daily intake of two or more servings of vegetables among Nepalese young adults using attitude, social influence, and self-efficacy (ASE) as a theoretical framework, extended with measures of habit and self-identity as additional constructs. Methods/Participants: A cross-sectional study through a web-based questionnaire survey was conducted among 461 Nepalese young adults aged 18-35 years old. Participants were recruited through convenience (snowball) sampling. A factor-based partial least square structural equation modelling was used for analysis. Results: The findings indicated that attitudes (β = 0.09, p = 0.029), social influence (β = 0.17, p < 0.001), habit (β = 0.24, p < 0.001) and self-identity (β = 0.30, p < 0.001) were significant factors influencing intention to eat two or more servings of vegetables per day. Further, self-efficacy (β = 0.10, p = 0.011), habit (β = 0.08, p = 0.034), diet (β = -0.10, p = 0.014), and place of residence (β = 0.11, p = 0.007) significantly influenced behaviour to eat two or more servings of vegetables per day. However, self-efficacy (β = 0.07, p = 0.062) did not significantly influence intention and self-identity (β = 0.06, p = 0.083), age (β = -0.02, p = 0.328), gender (β = 0.02, p = 0.350), and body mass index (β = -0.04, p = 0.209) did not significantly influence behaviour to eat two or more servings of vegetables per day. Conclusion: The study shows that attitudes, social influence, habit, and self-identity were significant factors influencing intention to eat two or more servings of vegetables per day. Further, self-efficacy and habit significantly influenced behaviour to eat two or more servings of vegetables per day. However, self-efficacy did not significantly influence intention and self-identity did not significantly influence behaviour to eat two or more servings of vegetables per day.

Abstract
This article discusses the overweight/obesity situation among young adults in developing countries. For this target population, obesity prevalence ranges from 2.3 to 12 %, and overweight is 28.8 %, mostly affecting females. Weight is now increasing during this life stage of transition at a higher rate, 1 kg/year, than in developed countries. Maternal factors and early childhood socioeconomic status are associated with BMI in young adults along with changing environmental and behavioural factors in some low and middle income countries, brought about by demographic and socioeconomic transitions. Young adults with 'normal weight' obesity need identification using other convenient low cost measures (skin folds or waist circumference) along with BMI. Obesity prevention or management interventions were not identified, but clearly needed to help stem the obesity pandemic. Young people generally give little priority to their future health, so such interventions need to be conducted at some optimal age, be innovative, country specific and culturally acceptable.

[PMID: 25750826 PMCID: PMC4346025 DOI: 10.1080/21642850.2014.931232] [Citation(s) in RCA: 75] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2013] [Accepted: 06/02/2014] [Indexed: 01/22/2023] Open
Abstract
Background: Young people (18-25 years) during the adolescence/adulthood transition are vulnerable to weight gain and notoriously hard to reach. Despite increased levels of overweight/obesity in this age group, diet behaviour, a major contributor to obesity, is poorly understood. The purpose of this study was to explore diet behaviour among 18-25 year olds with influential factors including attitudes, motivators and barriers. Methods: An explanatory mixed method study design, based on health Behaviour Change Theories was used. Those at University/college and in the community, including those Not in Education, Employment or Training (NEET) were included. An initial quantitative questionnaire survey underpinned by the Theory of Planned Behaviour and Social Cognitive Theory was conducted and the results from this were incorporated into the qualitative phase. Seven focus groups were conducted among similar young people, varying in education and socioeconomic status. Exploratory univariate analysis was followed by multi-staged modelling to analyse the quantitative data. 'Framework Analysis' was used to analyse the focus groups. Results: 1313 questionnaires were analysed. Self-reported overweight/obesity prevalence was 22%, increasing with age, particularly in males. Based on the survey, 40% of young people reported eating an adequate amount of fruits and vegetables and 59% eating regular meals, but 32% reported unhealthy snacking. Based on the statistical modelling, positive attitudes towards diet and high intention (89%), did not translate into healthy diet behaviour. From the focus group discussions, the main motivators for diet behaviour were 'self-appearance' and having 'variety of food'. There were mixed opinions on 'cost' of food and 'taste'. Conclusion: Elements deemed really important to young people have been identified. This mixed method study is the largest in this vulnerable and neglected group covering a wide spectrum of the community. It provides evidence base to inform tailored interventions for a healthy diet within this age group.

Abstract
BACKGROUND Young people (18-25 years) during the adolescence/adulthood transition are vulnerable to weight gain and notoriously hard to reach. Despite increased levels of overweight/obesity in this age group, physical activity behaviour, a major contributor to obesity, is poorly understood. The purpose of this study was to explore physical activity (PA) behaviour among 18-25 year olds with influential factors including attitudes, motivators and barriers. METHODS An explanatory mixed method study design, based on health Behaviour Change Theories was used. Those at university/college and in the community, including those Not in Education, Employment or Training (NEET) were included. An initial self reported quantitative questionnaire survey underpinned by the Theory of Planned Behaviour and Social Cognitive Theory was conducted. 1313 questionnaires were analysed. Results from this were incorporated into a qualitative phase also grounded in these theories. Seven focus groups were conducted among similar young people, varying in education and socioeconomic status. Exploratory univariate analysis was followed by multi staged modelling to analyse the quantitative data. 'Framework Analysis' was used to analyse the focus groups. RESULTS Only 28% of 18-25 year olds achieved recommended levels of PA which decreased with age. Self-reported overweight/obesity prevalence was 22%, increasing with age, particularly in males. Based on the statistical modelling, positive attitudes toward PA were strong predictors of physical activity associated with being physically active and less sedentary. However, strong intentions to do exercise, was not associated with actual behaviour. Interactive discussions through focus groups unravelled attitudes and barriers influencing PA behaviour. Doing PA to feel good and to enjoy themselves was more important for young people than the common assumptions of 'winning' and 'pleasing others'. Further this age group saw traditional health promotion messages as 'empty' and 'fear of their future health' was not a motivating factor to change current behaviour. CONCLUSION 18-25 year olds are a difficult group to reach and have low levels of PA. Factors such as, 'enjoyment', 'appearance 'and 'feeling good' were deemed important by this specific age group. A targeted intervention incorporating these crucial elements should be developed to improve and sustain PA levels.

Abstract
PURPOSE To examine the impact of a peer-led asthma education program on asthma knowledge, attitudes, and quality of life among adolescents. METHODS A controlled trial was conducted in two girls' high schools situated in an area of high unemployment and low socioeconomic status, and with a large non-English-speaking community. One school received the intervention and the second school acted as a comparison school. The Triple A (Adolescent Asthma Action) program was implemented in the intervention school and involved Year 11 student peer leaders instructing Year 10 students about asthma. The Year 10 students then developed asthma-related health messages into student asthma performances which were presented to the main student body. Outcomes were evaluated by questionnaire. RESULTS The Triple A program led to a significant improvement in asthma knowledge in both students with asthma and their peers. This effect occurred not only in students conducting the asthma performances (Year 10), but also in students in the audience (Year 7). Students held favorable attitudes toward asthma, with high degrees of tolerance and moderate internal locus of control. Asthma-related quality of life was not altered by the intervention. CONCLUSION Peer-led asthma education was well received in the high school setting and led to important improvements in asthma knowledge among students with asthma and their peers.

Abstract
Young women are a specific population that is falling short of performing what is considered to be an optimal level of physical activity. The purpose of this study was to determine the ability of nine explanatory variables to predict physical activity in a sample of average-weight (n = 225) and overweight (n = 115) young women. Personal control, race, regular participation in organizations and groups, and interpersonal support were the significant predictors of physical activity in overweight women. For average-weight women, only three variables--personal control, regular participation, and race--were significantly related to physical activity. Recreational activity was routinely performed by 25% of the women. Of the 14% who reported regular vigorous physical activity, 26% were White and 10% were Black. The findings suggest that nurses in community settings design interventions that are sex and race specific and that include personal-control skill building, interpersonal support systems, and multiple forms of physical activity, particularly recreational forms.
