Who's Feeding the Kids Online? Digital food marketing to children in Ireland: Advertisers’ tactics, children’s exposure and parents’ awareness

Obesity in children and young people is a global health challenge. The widespread marketing of unhealthy foods (food and non-alcoholic drinks high in fat, sugar and salt, or HFSS) plays a causal role in unhealthy eating and obesity. Food and eating is typically presented as an issue of ‘choice’. However, this disregards the fact that current obesogenic environments use many tactics to promote unhealthy foods, interfering with people’s ability to make good choices. This study examined: 1. Content appealing to children and young people on websites of top food and drink retail brands in Ireland 2. Marketing techniques on Facebook: Pages of food brands that have the highest reach among young teens, the first such study of which we are aware 3. Parents’ awareness of digital food marketing to their children in an online, two-stage survey with digital marketing examples and open-ended response options

Adolescents׳ perceptions of peers with depression: An attributional analysis

Understanding adolescents׳ perceptions of peers with depression is vital in order to tackle peer exclusion and lessen stigmatization. To examine adolescents׳ perceptions of a hypothetical peer with depression, we test an attributional model: that stigma towards persons with mental disorders is influenced by attributions about the causes of their disorders and inferences of personal responsibility. Participants were 401 adolescents from 4th year/10th grade with an age range of 14.75–17.08 years (M=15.90 years; S.D.=0.403 years). Structural Equation Modeling was employed to assess the relationships among causal attributions (personal control), perceived responsibility, and emotional reactions, in predicting social acceptance/exclusion of a peer with depression. Results indicated that (a) if the peer with depression is perceived as having little control over the cause of depression, responsibility is not inferred, participants feel sympathy and pity, and are likely to socially accept the peer (b) gender of vignette character and participant influence these responses. This study builds on our theoretical understanding of why adolescents with depression may face social exclusion from peers by applying a well‐established theory in social psychology. Findings should be incorporated into the design of interventions aimed at reducing peer exclusion and stigmatization of adolescents with depression

Labelling effects and adolescent responses to peers with depression: an experimental investigation

Background: The impact of illness labels on the stigma experiences of individuals with mental health problems is a matter of ongoing debate. Some argue that labels have a negative influence on judgments and should be avoided in favour of information emphasising the existence of a continuum of mental health/illness. Others believe that behavioral symptoms are more powerful influencers of stigma than labels. The phenomenon has received little attention in adolescent research, despite the critical importance of the peer group at this developmental stage. This study employs a novel experimental design to examine the impact of the depression label and continuum information on adolescents' responses to peers with depression. Methods: Participants were 156 adolescents, 76 male, 80 female (M = 16.25 years; SD = .361), assigned to one of three conditions (Control, Label, Continuum). Participants respond to four audio-visual vignette characters (two clinically depressed) on three occasions. Outcome measures included judgment of the mental health of the vignette characters and emotional responses to them. Results: Neither the provision of a depression label or continuum information influenced perceptions of the mental health of the characters in the audio-visual vignettes or participants' emotional responses to them. Conclusion: The findings have implications for the design of interventions to combat depression stigma with adolescents. Interventions should not necessarily target perceptions of psychiatric labels, but rather perceptions of symptomatic behaviour

Risky sex behaviours among college students: The psychosocial profile.

AIMS: Risky sex behaviours among college students are a growing public health concern. However, few studies have profiled these behaviours using a large range of psychosocial correlates. METHODS: Participants were 6874 undergraduate and postgraduate students (64.7% female, age range 17-25 years, M = 20.43 years, SD = 1.86 years) drawn from 13 higher-level institutions in Ireland. RESULTS: Regarding prevalence, 75% of the sample report that they have been, or are currently sexually active. Of this sexually active cohort (n = 5111), 27.2% report early sexual initiation, 29.5% report 5 or more lifetime sexual partners and 12.1% report 2 or more sexual partners in the past 3 months. In addition, 47.7% of students report inconsistent condom use and 39.5% report inconsistent use of other contraceptive methods in the past 3 months. Using multivariate logistic regression analyses, significant correlates of risky sex behaviour are identified across 5 groups of psychosocial predictors (demographic, sexuality and relationships, substance use, mental well-being and personal resources). Differences between males and females and between different sexual orientations are highlighted. CONCLUSIONS: Suggestions are made for sexual education and intervention programs to specifically target subgroups of the student population

Prevalence and correlates of psychotic like experiences in a nationally representative community sample of adolescents in Ireland

Adolescent psychotic like experiences (PLEs) are an important area of research, yet only a small number of community surveys have investigated their psychosocial correlates. This study presents the prevalence and correlates of three types of PLEs in a nationally representative community sample of 12–19 year olds in Ireland (N = 5910). Correlates are considered across five domains: demographic, stressful life experiences, emotional/behavioral problems, substance use, and personal resources. Auditory hallucinations were reported by 13.7% of participants, 10.4% reported visual hallucinations and 13.1% reported paranoid thoughts. Participants who had experienced two of the three PLEs were assigned “risk” status (10.4%; n = 616). Using binary logistic regression, PLEs were associated with a range of correlates across the five domains. Key correlates of risk status include depression (OR 4.07; 95% CI 3.39–4.88), low self-esteem (OR 4.03 95% CI 3.34–4.86), low optimism (OR 3.56; 95% CI 2.96–4.28), school misconduct (OR 3.10 95%; CI 2.56–3.75), and high avoidance coping (OR 2.86 95% CI 2.34–3.49). These associations remained significant in a multivariate analysis. While correlates for each of the three PLEs were similar, there were some nuances in these patterns. Notably, demographic and substance use variables were the weakest groups of correlates. Personal resources (e.g. self-esteem, optimism and coping) have been poorly studied in the adolescent PLE literature and these findings provide important insights for future research and intervention design

Modeling problem behaviors in a nationally representative sample of adolescents.

Research on multiple problem behaviors has focused on the concept of Problem Behavior Syndrome (PBS). Problem Behavior Theory (PBT) is a complex and comprehensive social-psychological framework designed to explain the development of a range of problem behaviors. This study examines the structure of PBS and the applicability of PBT in adolescents. Participants were 6062 adolescents; aged 12-19 (51.3% female) who took part in the My World Survey-Second Level (MWS-SL). Regarding PBS, Confirmatory Factor Analysis established that problem behaviors, such as alcohol and drug use loaded significantly onto a single, latent construct for males and females. Using Structural Equation Modeling, the PBT framework was found to be a good fit for males and females. Socio-demographic, perceived environment system and personality accounted for over 40% of the variance in problem behaviors for males and females. Our findings have important implications for understanding how differences in engaging in problem behaviors vary by gender

Dissociable psychosocial profiles of adolescent substance users.

OBJECTIVE: Alcohol, tobacco and cannabis use in adolescence is associated with adverse outcomes. Characterizing adolescent substance misusers, however, is difficult due to the wide range of risk and protective factors linked to substance use. The aim of the present study was to examine the role of the Individual, Family, School, Peer, and Social Environment on alcohol (lifetime and risky), tobacco (risky only), and cannabis use (lifetime and riskiness). METHOD: Data were analyzed from a national sample of 5,680 adolescents, capturing substance use behavior alongside risk and protective factors across Individual, Family, School, Peer and Social domains. We applied a sophisticated machine learning classifier to develop models of alcohol, tobacco and cannabis initiation and misuse. RESULTS: We found highly accurate (area under curve of receiver-operator-characteristic for out-of-sample performance was > .88) and replicable (over multiple iterations and in comparison with permuted outcomes) dissociable psychosocial profiles of alcohol, tobacco and cannabis use. Alongside common predictors (peer relations and externalizing behavior), dissociable risk and resilience factors were observed. Adolescent profiles of alcohol use were distinguished by the contribution of multiple domains. In contrast, tobacco use was characterized by a small number of individual variables, including female gender and poor perceived academic position. Cannabis use was differentiated by the distinct contribution of Individual risk factors, in particular male gender and feelings of anger. Differential associations were also evident, with the strength and direction of association differing substantially across substances. CONCLUSION: This study indicates that the relationship between the environment and substance use is more complex than previously thought

JWST Observations Reject Unrecognized Crowding of Cepheid Photometry as an Explanation for the Hubble Tension at 8σ Confidence

We present high-definition observations with the James Webb Space Telescope (JWST) of >1000 Cepheids in a geometric anchor of the distance ladder, NGC 4258, and in five hosts of eight Type Ia supernovae, a far greater sample than previous studies with JWST. These galaxies individually contain the largest samples of Cepheids, an average of >150 each, producing the strongest statistical comparison to those previously measured with the Hubble Space Telescope (HST) in the near-infrared (NIR). They also span the distance range of those used to determine the Hubble constant with HST, allowing us to search for a distance-dependent bias in HST measurements. The superior resolution of JWST negates crowding noise, the largest source of variance in the NIR Cepheid period–luminosity relations (Leavitt laws) measured with HST. Together with the use of two epochs to constrain Cepheid phases and three filters to remove reddening, we reduce the dispersion in the Cepheid P – L relations by a factor of 2.5. We find no significant difference in the mean distance measurements determined from HST and JWST, with a formal difference of −0.01 ± 0.03 mag. This result is independent of zero-points and analysis variants including metallicity dependence, local crowding, choice of filters, and slope of the relations. We can reject the hypothesis of unrecognized crowding of Cepheid photometry from HST that grows with distance as the cause of the “Hubble tension” at 8.2 σ , i.e., greater confidence than that of the Hubble tension itself. We conclude that errors in photometric measurements of Cepheids across the distance ladder do not significantly contribute to the tension
