Müller N, Fallucchi F, Suhrcke M. Peer effects in weight-related behaviours of young people: A systematic literature review. ECONOMICS AND HUMAN BIOLOGY 2024; 53:101354. [PMID: 38301414 DOI: 10.1016/j.ehb.2024.101354] [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: 06/05/2023] [Revised: 01/21/2024] [Accepted: 01/21/2024] [Indexed: 02/03/2024]
Abstract
Individual preferences and beliefs are perpetually shaped by environmental influences, with peers playing a key role in this dynamic process. Compelling evidence from qualitative and quantitative studies has highlighted the significant impact of peer influence on health-related decisions. This systematic literature review critically synthesises findings from 45 studies published between 2011 and 2022, providing a comprehensive understanding of the nature of peer effects on dietary, physical activity and sleep behaviours during youth. The majority of studies indicated that social norms drive directional changes in eating and physical activity. Yet, our analysis revealed a notable gap in exploring alternative mechanisms, including social comparison and social identity, despite their potential relevance. Studies, generally classified as moderate to high quality, predominantly relied on self-reported data, potentially affecting the validity and reliability of measures. Meta-regression analyses suggest a small, but significant association of sample size with the magnitude, sign and significance of the reported peer effects. Moreover, studies focusing on physical activity are more likely to report significant outcomes, whereas findings on peer influence on sleep-related studies tend to reveal less pronounced effects, compared to studies on dietary behaviours. Experimental designs do not appear to increase the likelihood of finding significant effects when compared to other study designs. In conclusion, this synthesis emphasises the need for further research into the underlying mechanisms on peer effects to better inform policy-makers in designing effective policies for improving weight-related behaviours in young people.

Boyle SC, Baez S, Trager BM, LaBrie JW. Systematic Bias in Self-Reported Social Media Use in the Age of Platform Swinging: Implications for Studying Social Media Use in Relation to Adolescent Health Behavior. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:9847. [PMID: 36011479 PMCID: PMC9408042 DOI: 10.3390/ijerph19169847] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 07/24/2022] [Accepted: 08/05/2022] [Indexed: 06/15/2023]
Abstract
Public health researchers are increasingly interested in the potential relationships between social media (SM) use, well-being, and health behavior among adolescents. However, most research has assessed daily SM time via self-report survey questions, despite a lack of clarity around the accuracy of such reports given the current tendency of youth to access SM on multiple electronic devices and cycle between multiple SM platforms on a daily basis (i.e., platform swinging). The current study investigates the potential for systematic reporting biases to skew findings. Three hundred and twenty incoming college students downloaded software on their computers, tablets, and smartphones to track their active use of Facebook, Twitter, Instagram, and Snapchat over a 2-week surveillance period and then self-reported their average daily minutes on each platform immediately after. Larger proportions of students over-estimated than under-estimated their use, with the largest overestimations found on the most heavily used platforms. Females logged significantly more SM time and were less accurate in reporting than were males and, independently, the likelihood of substantial inaccuracies in reporting total SM time and time on most individual platforms increased with each additional SM platform participants reported using. Findings demonstrate that self-reported estimates of SM time among adolescents in the age of SM platform swinging are prone to substantial error and may lead to biased conclusions about relationships between variables. Alternative measurement approaches are suggested to improve the validity of future research in this area.

Abstract
PURPOSE OF REVIEW Behavioral economics (BE) concepts have become well studied tools in addressing patient issues, such as weight loss, smoking cessation, and medication adherence. Although predominantly studied in adult populations, emerging literature has shown BE's utility for adolescent/young adult (AYA) populations, offering a practical framework to safeguard AYA health and influence healthy decision making. RECENT FINDINGS We identified substantive areas in which BE concepts have been applied in AYA populations (e.g., substance use) and outline how these concepts have been used as a tool to identify individuals at risk for poor outcomes and to leverage behavioral insights to improve health behaviors. SUMMARY BE research holds significant promise as a tool for clinicians and researchers to encourage healthy decision making in AYA populations. Yet, there are opportunities for BE research to expand further into current trends impacting adolescent health, such as electronic nicotine delivery systems, social media apps, and coronavirus disease 2019 vaccinations. Furthermore, the full degree of BE utility remains to be explored, as few studies demonstrate the translation of associative findings into direct interventions. Additional work is needed to formalize BE techniques into best practices that clinicians can implement in their daily practice.

Abstract
The purpose of the current study is to prospectively examine the extent to which social norms perceptions regarding commitment to ending sexual violence are associated with subsequent peer victimization and perpetration experiences. Two types of social norms perceptions were examined: 1) peer norms (perceptions of norms among other students in their city), and 2) adult norms (perceptions of norms among adults in their city). Participants were 1259 middle and high school youth from a single school district (three high schools and five middle schools) who completed online surveys at two-time points, 6 months apart. Adolescents for whom perceptions of peer norms were one standard deviation or more above and below the mean of actual norms were "over-perceivers" and "under-perceivers," respectively. Overperceivers overestimated their peers' commitment to ending sexual violence, whereas underperceivers underestimated their peers' commitment to ending sexual violence. Other adolescents were "accurate perceivers"; these adolescents were accurate in their estimation of their peers' commitment to ending sexual violence. In general, underperceivers (22.2% of the sample) were more likely than accurate perceivers (77.8% of the sample) to subsequently experience peer-to-peer perpetration and victimization. Adolescents who perceived adults to have a higher commitment to ending sexual violence were less likely to report subsequent perpetration and victimization for some forms of peer-to-peer violence. These findings highlight the potential promise of the social norms approaches to prevent peer-to-peer violence among youth which aligns with increasing calls in the field to integrate these approaches into comprehensive sexual violence prevention.

Abstract
PURPOSE Little is known about the influence of social network support on child health behaviors in the context of weight-loss interventions. This study examined the associations between a child's co-participation (i.e., network support) in weight-related health behaviors (i.e., physical and sedentary activity, eating behavior) and the child's own health behaviors during family-based behavioral treatment (FBT). METHODS Children (n = 241) with overweight/obesity (mean age = 9.4 ± 1.3y; 63% female) completed semi-structured interviews assessing network support for healthy/unhealthy eating and physical/sedentary activity, and a 3-day dietary recall. Physical activity was assessed with accelerometry, and sedentary activity was measured via parent-reported child screen time use. All assessments were taken at baseline and after 4 months of FBT. Hierarchical linear regressions examined changes in network support as they related to changes in health behaviors from baseline to the end of FBT. RESULTS Changes in network support for healthy eating were related to changes in vegetable, but not fruit, intake across FBT, while changes in network support for unhealthy eating were negatively related to changes in diet quality. Changes in network support for sedentary activity were negatively related to changes in minutes of physical activity and positively related to changes in screen time. CONCLUSION The present findings suggest that a child's network support for health behaviors may relate to behavior change among children during FBT and provide opportunities for targeted intervention.

Br J Health Psychol 2022; 27:891-914. [PMID: 35080782 DOI: 10.1111/bjhp.12581] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2021] [Revised: 12/20/2021] [Indexed: 12/01/2022]
Abstract
OBJECTIVES Adolescents tend to overestimate the extent of peers' unhealthy snacking consumption and such misperceptions have been associated with increased personal unhealthy snacking. This study aims to test whether a Social Norms Approach (SNA) intervention which challenges these misperceptions of peers' unhealthy snacking will have a positive effect on students' personal unhealthy snacking behaviours, related attitudes, and behavioural intentions. DESIGN A quasi-experimental study tested the effectiveness of an in-school SNA intervention (n = 163) compared to a control condition (n = 95) among 11-12-year-old students. METHOD Both conditions received healthy eating information, while students in the SNA intervention received additional normative feedback (outlining the discrepancies between perceived and actual unhealthy snacking of the majority based on baseline data) delivered through an interactive poster-making session. Students completed self-reported measures of personal unhealthy snacking, related-attitudes, behavioural intentions, and normative perceptions (descriptive and injunctive) at baseline, post-intervention, and at a 3-month follow-up. RESULTS Students who received SNA feedback were significantly less likely to overestimate peers' unhealthy snacking attitudes post-intervention (F(1,232) = 16.405, p < .001), and at 3-month follow-up consumed fewer unhealthy snacks (F(1,232) = 6.133, p = .014) and had less positive attitudes towards unhealthy snacking (F(1,198) = 8.779, p = .003). The changes in personal snacking attitudes at 3-month follow-up were mediated by changes in normative misperceptions about peers' unhealthy snacking attitudes post-intervention, which indicated that the reductions in normative misperceptions following SNA messages mediated the effect of the intervention. CONCLUSION The results indicate that in-school SNA interventions which challenge normative misperceptions constitute a promising strategy for reducing unhealthy snacking in young adolescents.

Overestimation of alcohol consumption norms as a driver of alcohol consumption: a whole-population network study of men across eight villages in rural, southwestern Uganda. Addiction 2022; 117:68-81.

Abstract
BACKGROUND AND AIMS Little is known about how perceived norms about alcohol consumption may influence high alcohol consumption rates in Uganda. This study estimated the accuracy of perceived norms about men's alcohol consumption and estimated the association between perceived norms and personal alcohol consumption. DESIGN Cross-sectional, whole-population, sociocentric social network study. SETTING Eight rural villages in Rwampara District, southwestern Uganda in 2016-18. PARTICIPANTS A total of 719 men aged 18 years and older (representing 91% of permanent resident men). MEASUREMENTS Self-reported frequent (≥ 4 days per week) and heavy alcohol consumption (six or more drinks on one occasion, more than three occasions of intoxication, or spending an excessive amount on alcohol). Participants also reported whether they thought most other men in their village engaged in frequent and heavy alcohol consumption (perceived norms). Using the network study design, we calculated alcohol consumption behavior within villages and social networks. Perceived norms were compared with aggregated self-reports. Multivariable Poisson regression models were used to estimate the association between perceived norms and individual behavior. FINDINGS Throughout villages, frequent and heavy alcohol consumption ranged from 7 to 37%. However, 527 (74%) participants perceived, contrary to fact, that most other men in their villages frequently consumed alcohol, and 576 (81%) perceived that most others heavily consumed alcohol. Overestimation of alcohol consumption by others was pervasive among socio-demographic subgroups and was present irrespective of the actual consumption behavior at the village level and within social networks. Men who misperceived these alcohol consumption behaviors as being common were more likely to engage in frequent [adjusted relative risk (aRR) = 3.98; 95% confidence interval (CI) = 1.69-9.34) and heavy (aRR = 4.75; 95% CI = 2.33-9.69) alcohol consumption themselves. CONCLUSIONS Most men in eight rural Ugandan villages incorrectly thought that frequent and heavy alcohol consumption were common among men in their villages. These misperceived norms had a strong positive association with individual drinking behavior.

Methodologic challenges and associations of perceived and actual friend behaviors with emerging adults' disordered eating and muscle building behaviors. Soc Sci Med 2021; 284:114224. [PMID: 34303935 DOI: 10.1016/j.socscimed.2021.114224] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2021] [Revised: 06/14/2021] [Accepted: 07/10/2021] [Indexed: 11/27/2022]
Abstract
Disordered eating and muscle building behaviors are common among emerging adults, and friends may be a particularly salient social influence. Epidemiologic research often includes questions about participants' perceptions of their friends. A less common approach, with greater logistical challenges, is to ask for friend nominations and then survey friends about their actual behaviors. The comparability of these different approaches is unknown. This study addresses the following research questions: 1) What is the feasibility of collecting data from emerging adults' friends in epidemiologic research? 2) Do perceptions of friends' weight- and shape-related behaviors align with friends' actual behaviors? and 3) Are perceptions or friends' actual behaviors more strongly and consistently associated with emerging adults' behaviors? Participants (N = 2383) in the EAT (Eating and Activity over Time)-2018 study in Minnesota, USA, were asked to nominate up to three friends and provide data about those friends' weight- and shape-related behaviors (i.e. perceptions); nominated friends were invited to complete an abbreviated survey and report on their own same behaviors (i.e. actual). Among the invited friends, 191 responded and were linked to the 152 EAT 2018 participants who nominated them. Descriptive statistics, Spearman's correlations, and logistic regression were used to address the research questions. The response rate for nominated friends was very low (9.9%), suggesting this approach may have low feasibility for epidemiologic studies of emerging adults. Emerging adults' perceptions of their nominated friends' weight and shape-related behaviors generally did not align well with the behaviors reported by those friends. Furthermore, analytic models found different associations between friends' behavior and EAT 2018 participant behaviors, depending on the measure of friends' behavior used (perceived or actual). Careful consideration of the pros and cons of each study design is essential to build an evidence base and support interventions regarding emerging adults' weight- and shape-related health.

Abstract
This study explores the relationship between the consumption of healthy and unhealthy foods and depression among young adults and the moderating effect of gender on these relationships. The National Longitudinal Survey of Youth 1979 for Children and Young Adults (NLSY79 CY) was used. A total of 2983 young adults were selected for the final sample. Logistic Regression Analysis and Ordinary Linear Regression were conducted to examine the research questions. Young men were overall more likely than young women to engage in negative eating habits. The consumption of healthy foods, which included fruits and vegetables, had a significant inverse relationship with depression. An interaction effect was found, indicating that gender moderated the relationship between fruit consumption and depression among young adults. Young males need to be taught more about the importance of good eating habits. Eating more fruits and vegetables (healthy foods) is more important than avoiding fast food or soft drinks (unhealthy foods) for young adults' mental health. The gender differences in the effect of fruit consumption implies that increased fruit consumption may be critical to reduce young females' depression.

Abstract
Younger adolescents are at an age where they have increasing control of their diet, and where peers become an important social reference for acceptable and normative dietary behaviours. These normative perceptions are often inaccurate and can lead to the development of unhealthy eating practices; although, the role of normative misperceptions of peers' unhealthy snacking behaviours in younger adolescents' personal snacking behaviours is not clear. The current study was a cross-sectional analysis of baseline data from a social norms-based healthy eating intervention sampling two secondary schools in deprived areas of England. Students aged 11-12 years (n = 252) completed self-report measures of their demographic characteristics and personal behaviours, attitudes, intentions, and normative perceptions (descriptive and injunctive norms), relating to unhealthy snacking. Results indicated students overestimated peers' daily unhealthy snacks consumption by approximately 3.2 portions, misperceived peers to have more positive attitudes towards unhealthy snacking and more negative attitudes towards reducing snacking. The greater these misperceptions of peers' behaviours and attitudes, the more likely students were to consume unhealthy snacks and have positive attitudes about unhealthy snacking. Girls had a stronger intention to reduce their snacking behaviours if they had more positive attitudes to reducing snacking behaviours and misperceived peers to also have a positive attitude. In summary, 11- to 12-year-olds misperceive the snacking behaviour and attitudes of their peers, and such normative misperceptions are associated with students' own snacking behaviours and attitudes. Interventions which challenge these misperceptions may assist in reducing the social acceptability of unhealthy snacking and in reducing unhealthy snacking amongst young adolescents.

Abstract
OBJECTIVE This study assesses tobacco use norm misperceptions by distinguishing between perceived and actual peer norms for both tobacco use attitudes and behavior, and examines the association between perceived norms and personal use among U.S. students in Grades 6-12. METHOD Anonymous self-report surveys were conducted with 28,070 students across 64 schools in 11 U.S. states between 1999 and 2017. RESULTS Although 77% of students said tobacco use is never good, 64% of students thought that most students in their grade believed that use is acceptable. Similarly, although 79% of students reported never using tobacco, 85% of students perceived that most students in their grade typically use tobacco, with 66% thinking that peers use monthly or more often. Substantial norm misperception existed regardless of student and school factors, increasing by grade. Perceiving that most peers thought tobacco use is acceptable was highly predictive of personal attitude, and perceiving tobacco use as the norm among same-grade peers strongly predicted personal tobacco use, even after we adjusted for actual peer use prevalence and other factors. Males' perception of the male peer norm was a stronger predictor of personal use than was their perception of the female peer norm. Females' perceptions of sex-specific norms were associated with personal use, each at about the same magnitude. CONCLUSIONS Norm misperceptions are pervasive across a diversity of students and schools, whereas perceptions of peer norms about tobacco use are highly associated with personal attitude and use. Results suggest that population-wide interventions correcting these misperceptions may help reduce tobacco use broadly among youth.

Abstract
Background People’s eating behavior is assumed to be influenced by what other people do (perceived descriptive norms) and what others approve of (perceived injunctive norms). It has been suggested that adolescents are more susceptible to peer norms than parental norms, because they experience a strong need for group acceptance that leads to conforming to peer group norms. The current study examined changes in snacking behavior and four types of social norms (i.e., parental and peer descriptive and injunctive norms) that promoted fruit and vegetable intake among adolescents. This study was the first to examine whether snacking behavior also influenced norm perceptions by testing the directionality of these associations. Methods The study consisted of 819 participants (M [SD] age = 11.19 [1.36]; 46.1% boys), collected at three time points (T1 = 2016, T2 = 2017 and T3 = 2018) during the MyMovez project. Self-reported frequency of snack consumption, perceived parental and peer descriptive and injunctive norms were assessed. The primary analysis consisted of a series of cross-lagged autoregressive models specified in a structural equation modeling framework. Results Model comparisons testing the descriptive and injunctive norms in separate models and in an additional combined model revealed evidence for bi-directional associations between norms and snacking behavior. Descriptive peer and parent norms were not found to have an effect on subsequent snacking behaviors. Perceived injunctive parental norms were positively associated with healthy snack food intake and negatively associated with unhealthy snack intake (forward direction). Injunctive peer norms were negatively associated with healthy snack food intake. In addition, higher unhealthy snack food intake was negatively associated with the perception of descriptive and injunctive parental norms 1 year later (reversed direction). We did not find peer norms to be more closely associated with changes in snacking behaviors compared to parental norms. Conclusions Parents expecting their children to snack healthy had a positive influence on healthy snacking behavior whereas only acting as a healthy role model did not. Future research should address the possible interaction between descriptive and injunctive norms. Research should also take into account the bi-directional relations between eating behaviors and normative perceptions.

Abstract
AbstractObjective:To identify correlates and underlying beliefs regarding the adolescents’ intention to abstain from consuming sugar-sweetened beverages (SSB) and the consumption of ≤1 daily portion of SSB.Design:Correlational study.Setting:Region of Chaudière-Appalaches in the province of Quebec, Canada.Participants:311 adolescents aged 13–18 years completed a self-administrated online questionnaire based on the Reasoned Action Approach. Frequency and quantity of different types of SSB within the past month were measured.Results:Total mean SSB intake was 882·6 ml/d (654·0 kJ/d ). Only 11·3 % abstained from SSB within the last month. Intention to abstain from SSB was explained by identification as SSB abstainers (β = 0·47), perceived norm (β = 0·32), attitude (β = 0·30), age 13–14 years (β = –0·27) and perception of the school environment (β = 0·14), which explained 66 % of the variance. Consumption of ≤1 daily portion of SSB was explained by the intention to abstain (OR = 1·55; 95 % CI 1·14, 2·11), perceived behavioural control to abstain (OR = 1·80; 95 % CI 1·29, 2·52), sex (girls v. boys: OR = 2·34; 95 % CI 1·37, 3·98) and socio-economic status (advantaged v. disadvantaged school: OR = 2·08; 95 % CI 1·21, 3·56). Underlying beliefs (i.e. more energy, decreased risk of addiction and friends’ approval) associated with intention as well as perceived barriers (e.g. access to SSB, after an activity that makes you thirsty), and facilitating factors (e.g. access to water) linked to SSB consumption were identified.Conclusions:The results can inform public health interventions to decrease SSB consumption and their associated health problems among adolescents.

Abstract
A detailed understanding of the factors associated with support among youth for reporting a knife or gun at school to an adult is essential to inform violence prevention initiatives. However, no studies have empirically assessed attitudes about support for reporting among secondary school students in Greater London nor perceived norms about such support among peers. Thus, this study explores whether students misperceive peer norms about support for telling adults about seeing weapons at school. Anonymous surveys were completed by 7401 youth (52% female; 43% White; mean age 11.8 years) in school years 4-11 in 45 school cohorts in a greater London borough between 2007 and 2012. Students reported both personal support about reporting weapons to several categories of adults and whether they perceived most other students at their school to support reporting weapons to adults in each category. Most students (64-78% on average) in most cohorts personally thought that students should report seeing a weapon at school to head teachers, police/security guard, teachers/counselors, and parent/other adult relatives. However, 34-44% of students erroneously thought that the majority of their peers did not support reporting to these adults. Perceived norms predicted personal support for reporting, adjusting for the prevalence of actual support at one's school and other factors. Pervasive norm misperceptions about reporting may contribute to a less safe environment.

Social norms, misperceptions, and mosquito net use: a population-based, cross-sectional study in rural Uganda. Malar J 2019; 18:189. [PMID: 31159821 PMCID: PMC6547474 DOI: 10.1186/s12936-019-2798-7] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2018] [Accepted: 05/03/2019] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND Mosquito net use is an essential part of malaria prevention. Although previous research has shown that many people sleep under a mosquito net in endemic areas, it is unknown whether people underestimate how common it is to sleep under a net every night. Furthermore, perceived social norms about whether most others sleep under a mosquito net every night may contribute to personally sleeping under a net, given decades of research showing that people often mimic others' behaviours. METHODS Population-based data were collected from 1669 adults across eight villages in one rural parish in southwestern Uganda. Individuals' perception about whether most adults in their community sleep under a mosquito net every night was compared with whether daily mosquito net use was the actual norm in their community to identify the extent of norm misperception. The association between whether an individual perceived daily mosquito net use to be the norm and personal mosquito net use was assessed while adjusting for the ratio of nets:people in the household and other factors. RESULTS Although the majority (65%) of participants reported sleeping under a mosquito net every night (and 75% did so among the 86% of people with at least one net), one-quarter of participants thought that most adults in their community did not sleep under a mosquito net every night. Another 8% were unsure how many nights per week most adults in their community sleep under a mosquito net. Participants who perceived that daily mosquito net use was the norm were 2.94 times more likely to report personally sleeping under a mosquito net every night (95% CI 2.09-4.14, p < 0.001) compared to participants who thought doing so was not normative, adjusting for other factors. CONCLUSIONS Results suggest an opportunity for anti-malarial interventions to reduce misperceptions about mosquito net use norms and emphasize the commonness of daily mosquito net use in malaria-endemic regions. If people correctly perceive most others to sleep under a net every night, then they may personally do so when possible and support others to do so too.
