Environmental enrichment enhances ethanol preference over social reward in male swiss mice: Involvement of oxytocin-dopamine interactions. Neuropharmacology 2024; 253:109971. [PMID: 38705568 DOI: 10.1016/j.neuropharm.2024.109971] [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: 12/22/2023] [Revised: 03/18/2024] [Accepted: 04/25/2024] [Indexed: 05/07/2024]
Abstract
The impact of environmental enrichment (EE) on natural rewards, including social and appetitive rewards, was investigated in male Swiss mice. EE, known for providing animals with various stimuli, was assessed for its effects on conditioned place preference (CPP) associated with ethanol and social stimuli. We previously demonstrated that EE increased the levels of the prosocial neuropeptide oxytocin (OT) in the hypothalamus and enhanced ethanol rewarding effects via an oxytocinergic mechanism. This study also investigated the impact of EE on social dominance and motivation for rewards, measured OT-mediated phospholipase C (PLC) activity in striatal membranes, and assessed OT expression in the hypothalamus. The role of dopamine in motivating rewards was considered, along with the interaction between OT and D1 receptors (DR) in the nucleus accumbens (NAc). Results showed that EE mice exhibited a preference for ethanol reward over social reward, a pattern replicated by the OT analogue Carbetocin. EE mice demonstrated increased social dominance and reduced motivation for appetitive taste stimuli. Higher OT mRNA levels in the hypothalamus were followed by diminished OT receptor (OTR) signaling activity in the striatum of EE mice. Additionally, EE mice displayed elevated D1R expression, which was attenuated by the OTR antagonist (L-368-889). The findings underscore the reinforcing effect of EE on ethanol and social rewards through an oxytocinergic mechanism. Nonetheless, they suggest that mechanisms other than the prosocial effect of EE may contribute to the ethanol pro-rewarding effect of EE and Carbetocin. They also point towards an OT-dopamine interaction potentially underlying some of these effects.

Lack of consistency in measurement methods and semantics used for network measures in adolescent health behaviour studies using social network analysis: a systematic review. J Epidemiol Community Health 2024; 78:303-310. [PMID: 38290822 DOI: 10.1136/jech-2023-220980] [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: 06/10/2023] [Accepted: 01/21/2024] [Indexed: 02/01/2024]
Abstract
BACKGROUND Social network analysis (SNA) is often used to examine how social relationships influence adolescent health behaviours, but no study has documented the range of network measures used to do so. We aimed to identify network measures used in studies on adolescent health behaviours. METHODS We conducted a systematic review to identify network measures in studies investigating adolescent health behaviours with SNA. Measures were grouped into eight categories based on network concepts commonly described in the literature: popularity, position within the network, network density, similarity, nature of relationships, peer behaviours, social norms, and selection and influence mechanisms. Different subcategories were further identified. We detailed all distinct measures and the labels used to name them in included articles. RESULTS Out of 6686 articles screened, 201 were included. The categories most frequently investigated were peer behaviours (n=201, 100%), position within the network (n=144, 71.6%) and popularity (n=110, 54.7%). The number of measurement methods varied from 1 for 'similarity on popularity' (within the 'similarity' category) to 28 for the 'characterisation of the relationship between the respondent and nominated peers' (within the 'nature of the relationships' category). Using the examples of 'social isolation', 'group membership', 'individuals in a central position' (within the 'position within the network' category) and 'nominations of influential peers' (sub within the 'popularity' category), we illustrated the inconsistent reporting and heterogeneity in measurement methods and semantics. CONCLUSION Robust methodological recommendations are needed to harmonise network measures in order to facilitate comparison across studies and optimise public health intervention based on SNA.

Abstract
Evidence suggests that being evicted harms health. Largely ignored in the existing literature is the possibility that evictions exert community-level health effects, affecting evicted individuals' social networks and shaping broader community conditions. In this narrative review, we summarize evidence and lay out a theoretical model for eviction as a community health exposure, mediated through four paths: 1) shifting ecologies of infectious disease and health behaviors, 2) disruption of neighborhood social cohesion, 3) strain on social networks, and 4) increasing salience of eviction risk. We describe methods for parsing eviction's individual and contextual effects and discuss implications for causal inference. We conclude by addressing eviction's potentially multilevel consequences for policy advocacy and cost-benefit analyses.

Abstract
School racial segregation is increasingly recognized as a threat to US public health: rising segregation in recent decades has been linked to a range of poor health outcomes for Black Americans. Key theorized mediators of these harms remain underexamined, including experiences of interpersonal and institutional racism driving increased stress, and peers' health behaviors influencing students' own. Using cross-sectional survey data on a national sample of adolescents, we investigated associations between school segregation and these two potential mediating pathways, operationalized as adolescents' perceptions of prejudice from fellow students and the health behaviors of their peers (drinking and smoking). We further investigated whether associations were modified by individual race/ethnicity and school racial composition. Pooling across all schools and students, higher levels of school segregation were associated with decreased perceptions of peer prejudice (OR 0.54, 95% CI = 0.34-0.86), but not with peers' health behaviors. However, this masked important differences by respondents' race/ethnicity and school racial/ethnic composition. In predominantly White schools, school segregation was not associated with Black students' perceptions of peers' prejudice, but higher levels of segregation were associated with increased rates of peers' drinking and smoking. In predominantly non-White schools, in contrast-where most Black students are educated-higher levels of school segregation were not associated with perceived peer prejudice nor unhealthier peer behaviors for Black students (in fact, peers' health behaviors improved). And across both school types, higher levels of district segregation were associated with lower odds of reporting peer prejudice among non-Black students of color. Our findings suggest that the paths between school segregation and poor health depend on the type of school children attend in segregated districts. In schools predominantly serving students of color, structural factors upheld by school segregation-i.e., material, educational, disciplinary, or economic disadvantage-likely dominate over peer behaviors as the primary drivers of segregation's health harms.

Abstract
Self-management includes all behavioural measures and cognitive activities aimed at coping with challenges arising throughout the lifespan. While virtually all of these challenges can be met without pharmacological means, alcohol consumption has long been instrumentalized as a supporting tool to help coping with problems arising selectively at adolescence, adulthood, and ageing. Here, we present, to our knowledge, the first systematic review of alcohol instrumentalization throughout lifespan. We searched MEDLINE, Google Scholar, PsycINFO and CINAHL (from Jan, 1990, to Dec, 2022) and analysed consumption patterns, goals and potential neurobiological mechanisms. Evidence shows a regular non-addictive use of alcohol to self-manage developmental issues during adolescence, adulthood, and ageing. Alcohol is selectively used to overcome problems arising from dysfunctional personality traits, which manifest in adolescence. A large range of psychiatric disorders gives rise to alcohol use for the self-management of distinct symptoms starting mainly in adulthood. We identify those neuropharmacological effects of alcohol that selectively serve self-management under specific conditions. Finally, we discuss the adverse effects and associated risks that arise from the use of alcohol for self-management. Even well-controlled alcohol use adversely impacts health. Based on these findings, we suggest the implementation of an entirely new view. Health policy action may actively embrace both sides of the phenomenon through a personalized informed use that allows for harm-controlled self-management with alcohol.

'The Addiction Was Making Things Harder for My Mental Health': A Qualitative Exploration of the Views of Adults and Adolescents Accessing a Substance Misuse Treatment Service. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:5967.

Abstract
The relationship between substance use and mental health is complex, and both constitute a global public health burden. In the UK, the estimated annual financial costs of alcohol-related harm and illicit drug use are GBP 21.5 billion and GBP 10.7 billion, respectively. This issue is magnified in the North East of England, where treatment access is low and a large proportion of individuals experience socioeconomic deprivation. The present study aimed to explore the experiences of adults and adolescents accessing a substance misuse treatment service in the North East, in order to inform policy makers, commissioners, and providers of substance misuse treatment and prevention. Semi-structured qualitative interviews were conducted with an opportunistic sample of n = 15 adult participants (aged 18 years and over) and n = 10 adolescent participants (aged between 13 and 17 years). Interviews were audio-recorded, transcribed, anonymised, and analysed thematically. Five key themes were identified: (1) initiation of substance use, (2) early life experiences, (3) the bi-directional relationship of mental health and substance use, (4) cessation of substance use, and (5) accessing treatment. Future preventative interventions should focus on providing support to individuals who have been exposed to adverse childhood experiences, with treatment provision for individuals experiencing co-occurring mental health and substance use issues taking a more holistic approach.

Abstract
BACKGROUND The main objective of this study was to investigate the association between parental supply of alcohol, alcohol-related harms, and the severity of alcohol use disorder in Thai 7th grade middle school students. METHODS A cross-sectional descriptive study obtained the baseline data from the project named the Thailand Parental Supply and Use of Alcohol, Cigarettes & Drugs Longitudinal Study Cohort in Secondary School Students in 2018. The sample size was 1187 students who have ever sipped or drank alcohol in the past 12 months. Pearson's Chi square, binary logistic regression, and ordinal logistic regression are applied in the analysis. RESULTS A single source of parental supply is not significantly associated with any alcohol-related harm and the severity of alcohol use disorder, while parental supply with peers and siblings supply of alcohol plays an important role in both outcomes. The increasing number of sources of alcohol supply increases the risk of alcohol-related harm and the severity of alcohol use disorder. Other risk factors found in both associations included binge drinking, alcohol flushing, low household economic status, distance from the student's family, and poor academic performance. Gender, exposure to alcohol ads on social media and location of residency were not associated with alcohol-related harms or severity of alcohol use disorder. CONCLUSIONS The results did not support parental guidance in teaching or giving children a drink or sip of alcohol within family to prevent related harms when drinking outside with their peers.

Abstract
A social network intervention is a process of intentionally altering a social network to achieve an objective. The objective in question may concern accelerating behaviour change or improving organisational performance. In this work we propose a novel model of social network interventions which considers topological properties of relationships existing between communities. Broadly speaking, topological properties of such relationships include properties described by natural language descriptions such as contains, partial overlap and disjoint. The proposed model provides an abstraction which in many cases is useful for solving problems involving social network interventions. We demonstrate this by simulating interventions on a number of hypothetical and real social networks in the domains of health and security.

Abstract
Although most schoolchildren can dispose of their own litter, they are typically not sensitive to environmental issues in the school’s public areas. How do we improve children’s sensitivity to public environments and cultivate pro-environmental behaviours? Based on Bandura’s social learning theory, this study explored the effects of various role models (teachers and peers) on the pro-environmental behaviours of children aged 7–13. A field study was conducted in which examples of postprandial garbage disposal behaviours were provided using role models and the subsequent behaviours of the children were observed. We located the experiment in a real educational context and manipulated the type of role model (teacher or peer) and the behaviour being modelled (positive behaviours involving picking up litter or negative behaviours involving littering). The results showed that different role models had different effects on the subjects’ pro-environmental behaviours. Only positive demonstration by teachers significantly improved the subjects’ pro-environmental behaviours, that is, teachers’ picking up of garbage in front of children significantly improved the children’s attention to the environment and their adoption of pro-environmental behaviours. Positive demonstration by peers, negative demonstration by teachers and negative demonstration by peers had no impact on the children’s pro-environmental behaviours. The results demonstrate that teachers must be mindful of their role as role models in the educational environment and facilitate students’ development of pro-environmental behaviours.

Social Network Drinking Feedback is Associated with Use of Protective Behavioral Strategies and Drinking-Related Outcomes in Emerging Adult Risky Drinkers. J Stud Alcohol Drugs 2022; 83:64-73.

Abstract
OBJECTIVE Although emerging adult risky drinkers are generally unmotivated to change their drinking, use of protective behavioral strategies (PBS) to minimize drinking risks is associated with decreased alcohol-related harms. However, research on social influences on PBS use and associations with drinking outcomes is limited and relevant to informing interventions for this priority population. This study investigated whether emerging adults' drinking-related behaviors were associated with social network encouragement, discouragement, or mixed messages about their drinking and with PBS use. METHOD Risky drinkers ages 21-29 years (N = 356; 228 women; mean age = 23.6 years) were recruited from the community using digitally implemented respondent-driven sampling. A web-based survey assessed social network drinking feedback, PBS use, drinking practices and problems, and behavioral allocation of time and money to drinking. RESULTS Negative binomial generalized linear models indicated that friend and spouse/ partner discouragement of drinking was associated with greater PBS use, whereas mixed messages were associated with lower use (ps < .05). Greater PBS use was associated with fewer alcohol-related negative consequences and lower behavioral allocation to drinking (ps < .05); the latter association was most consistent for serious harm reduction PBS (e.g., use of a designated driver). Mixed drinking messages from all relationship types had direct negative associations with drinking outcomes, particularly time and money allocated to drinking. CONCLUSIONS Assessing social network features may guide interventions to increase PBS use and reduce drinking-related harms among emerging adult risky drinkers.

Abstract
Peer influence occurs across a wide variety of behavioral domains, which is an important reason for peer-led interventions: interventions in which peers are involved in the delivery of the program. These programs are promising in combatting undesirable behaviors (e.g. risk behavior) and promoting desirable behavior (e.g. healthy lifestyle), but it was shown recently that the effectiveness of these programs is modest at best and the mechanisms underlying programs' effectiveness are poorly understood. Research is needed that promotes understanding of the relative, cumulative, and interactive impacts of different types of peer relations and unpacks the various mechanisms underlying peer selection and influence. This has the potential to yield insights that advance theory and optimize peer-led interventions.
