Ethnic inequality between Arabs and Jews in Israel in global life satisfaction: A social determinants examination among young adults.

Global life satisfaction (GLS), a core construct of subjective well-being, plays a vital role in positive development among young adults. Persistent inequality in subjective well-being across minority versus majority groups is a growing public health concern. However, research evidence on the minority-majority disparity in GLS among representative samples of young adults is scarce. Based on national data from Israel (N = 2,405), this study examines (a) the association of multiple forms of economic (not in education, employment, or training status, subjective socioeconomic status indicators), social-relational (trust, discrimination, loneliness), and environmental determinants (neighborhood conditions) with GLS among young adults from a minority-majority (Israeli Arabs-Israeli Jews) perspective; (b) whether minority-majority disparity in GLS can be explained by differential health returns for the determinants considered across participants from the two groups; (c) whether minority-majority disparities in GLS persist when controlling for these determinants, suggesting the effect of ethnicity per se. Significant disparities in GLS by ethnicity were found, with young Arab adults far less likely to be satisfied or very satisfied with their lives. Hierarchical logistic regression indicated that economic, social-relational, and environmental determinants shape GLS, but these factors do not eliminate the adverse effect of minority status on GLS. While social-relational and environmental factors uniformly affect GLS across minority and majority participants, economic factors were less influential among the Arab minority, suggesting lower health returns for economic resources among young Arab adults. Implications for policies aimed at promoting health equity and social justice are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Internet-Based Recruitment and Retention of Young Adults With Type 1 Diabetes: Cross-Sectional Study.

Multiple research strategies are required to recruit and engage a representative cohort of young adults in diabetes research. In this report, we describe an approach for internet-based recruitment for a repeated-measures descriptive study. The objective of this cross-sectional study was to determine whether internet-based recruitment through multiple social media platforms, a clinical research platform, and cooperation with community partnerships-College Diabetes Network and Beyond Type 1-would serve as an effective way to recruit a representative sample of young adults aged 18-25 years with type 1 diabetes (T1D). We conducted a repeated-measures descriptive study. We captured enrollment rates and participant characteristics acquired from each social media platform through survey data and Facebook analytics. This study was advertised via paid postings across a combination of different social media platforms (eg, Facebook, Instagram, Twitter, and Reddit). We used quarterly application postings, quarterly newsletters, and participation in the ResearchMatch registry to identify potentially eligible participants from February 3, 2021, to June 6, 2022. ResearchMatch proved to be the most cost-effective strategy overall, yielding the highest gender and racial diversity compared to other internet platforms (eg, Facebook, Instagram, Twitter, and Reddit), application postings (eg, Beyond Type 1), and newsletters (eg, College Diabetes Network and a local area college). However, we propose that the combination of these approaches yielded a larger, more diverse sample compared to any individual strategy. Our recruitment cost was US $16.69 per eligible participant, with a 1.27% conversion rate and a 30% eligibility rate. Recruiting young adults with T1D across multiple internet-based platforms was an effective strategy to yield a moderately diverse sample. Leveraging various recruitment strategies is necessary to produce a representative sample of young adults with T1D. As the internet becomes a larger forum for study recruitment, participants from underrepresented backgrounds may continue engaging in research through advertisements on the internet and other internet-based recruitment platforms.

Is sexual attraction and place of origin a moderator of sex in pornography consumption? Cross-sectional study on a representative sample of young adults

BackgroundPornography consumption is higher in men, but we do not know if this association can be modified by different variables, such as sexual attraction and place of origin. Given the impact pornography has on minors, there are limited studies that analyze the use of pornography in representative samples of the adult population. The aim was analyze the prevalence and factors associated with using pornography in young adult men and women, living in Spain, with different sexual attractions and different places of birth.MethodsCross-sectional study with an online survey conducted with 2515 men and women aged between 18 and 35 years of age. The prevalence of pornography consumption is described and analyzed in the total sample and stratified by sex, according to socio-demographic and sexual attraction variables. The association between covariates and pornography consumption at some point in life was estimated with prevalence ratios (PR) obtained with the Poisson models of robust variance. Dependent variable: voluntarily using pornography at some point in life. Socio-demographic variables were included in the analysis: age, sex, level of education, place of birth. Sexual attraction was also analyzed.ResultsIn Spain, 94.7% of men between 18 and 34 years and 74.6% of women have voluntarily used pornography at some point in their life. The mean age to start using it is earlier in men [Mean:14.2; Standard Deviation (SD):2.3]. Bisexual/homosexual attraction (reference: heterosexual) increases the probability of using pornography in women [(PR (95%CI): 1.30 (1.22; 1.38)]. Yet this is not observed in men. In both sexes, the probability of using pornography increases with age [(PR (95%CI): 1.01(1.00; 1.01)] and coming from abroad (reference: native), being the effect of country of birth significantly higher in women [(PR (95%CI): 1.17 (1.09; 1.26)] than in men [(PR (95%CI): 1.04 (1.01; 1.07).ConclusionsPublic health programmes aimed at improving affective-sexual health should consider the high use of pornography among young adults in Spain, as well as those variables that increase its use.

The Reflective Functioning Questionnaire-Revised- 7 (RFQ-R-7): A new measurement model assessing hypomentalization.

Although it is a widely used questionnaire, limitations regarding the scoring procedure and the structural validity of the eight-item Reflective Functioning Questionnaire (RFQ-8) were raised. The present study aimed to examine further the latent dimensionality of the RFQ-8 and to examine linear and non-linear associations between mentalization difficulties and maladaptive psychological characteristics. Data from two separate representative samples of young adults (N = 3890; females: 51.68%; mean age: 27.06 years [SD = 4.76]) and adults (N = 1385; females: 53.20%; mean age: 41.77 years [SD = 13.08]) were used. In addition to the RFQ-8, standardized questionnaires measured the levels of impulsivity, sensation seeking, rumination, worry and well-being. Confirmatory factor analysis (CFA) was used to test the model fit of competing measurement models. CFA revealed that a revised, seven-item version of the RFQ (RFQ-R-7) with a unidimensional structure showed the most optimal levels of model fit in both samples. Impulsivity, sensation seeking, rumination and worry consistently presented significant, positive, linear associations with general mentalization difficulties in both samples. Significant quadratic associations were also identified, but these relationships closely followed the linear associations between the variables and increased only marginally the explained variance. The supported unidimensional measurement model and the associations between the general mentalization difficulties factor and maladaptive psychological characteristics indicated that the RFQ-R-7 captures a dimension of hypomentalization ranging between low and high levels of uncertainty. Increasing levels of hypomentalization can indicate a risk for less adaptive psychological functioning. Further revisions of the RFQ-8 might be warranted in the future to ensure adequate measurement for hypermentalization.

Feasibility of mailed biomarker data collection among U.S. young adults: Saliva-based cotinine and self-reported nicotine use

BackgroundNationally representative self-report studies are the standard for data on the prevalence of substance use. Newly emerging biomarker assessments can add objective measurements of exposure. However, biomarker assessment has typically depended on in-person sample collection. The current study examined whether young adults in a national sample would be willing and able to provide a saliva sample via mail, and the correspondence of cotinine in the saliva sample with self-reported vaping and smoking. MethodsData collection for the Monitoring the Future (MTF) Vaping Supplement was from September to November 2020. Eligible participants (N = 4358) were selected from a nationally-representative sample of US 12th-grade students in MTF in spring 2019. The MTF Vaping Supplement surveyed individuals nationally about one year after the 12th grade MTF survey (in 2020, mean age = 19.6 years; N = 1244). Survey weights accounted for design and attrition. ResultsOf those surveyed, 66.2% consented to provide a saliva sample and, of those, 73.8% mailed a sample. There were no significant differences in providing a saliva sample across any demographic characteristic, but those who reported nicotine use were less likely to provide a sample. Cotinine cut-off measures of > 3 ng/mL and > 10 ng/mL had good correspondence with self-reported measures. ConclusionsResults support the feasibility of collecting saliva via the mail in a national sample and the validity of data collected in this way. These findings support future research innovations to expand existing survey research protocols to include biomarker data collection in representative samples of young adults.

A comprehensive examination of discrimination and the impact on health in young adults

Research has begun to clarify links between discrimination and health, but important gaps remain. A more complete understanding may arise from data on both frequency of discrimination as well as the various forms of discrimination. Using unique Panel Study of Income Dynamics (PSID) Transition to Adulthood Supplement (TAS) data on a representative sample of young adults from the 2017 and 2019 waves, we consider frequency and forms of discrimination separately and in tandem. Using generalized estimating equations panel models, we find that the association between discrimination and health is more pronounced when the frequency of, and the number of reasons for, discriminatory experiences are considered together. For example, relative to experiencing no discrimination, perceiving frequent discrimination and for three or more reasons results in nearly three times higher odds of poor/fair self-rated health and 1.25 points lower on the languishing/flourishing scale. The impact of perceived discrimination on health is likely underestimated if frequency and rationale are not considered as a holistic experience.

Inequality in psychological distress among young adults: An integrative model of economic, social, and environmental determinants.

Differences in economic, social, and environmental circumstances lead to systematic and unfair health inequalities. Yet, this inequality is modifiable. Drawing on the social determinants approach to health this study explored: (a) the association between economic, social-relational, and environmental stressors with psychological distress (PD) among a representative sample of young adults in Israel (N = 2,407); (b) the collective impact of these multiple stressors on PD and the extent to which the co-occurrence of stressors demonstrated a stepped relationship with PD. Social determinants included subjective poverty, perceived income adequacy, material deprivation indices, social trust, trust in institutions, perceived discrimination, loneliness, and indicators for the quality of the neighborhood environment. Bivariate analysis was used to assess associations between economic, social-relational, and environmental stressors with PD. Hierarchical linear regressions, estimated to predict PD, showed that the social determinants shaped PD in young adulthood, with each stressor domain making a distinct contribution to explaining PD. Subjective poverty, material deprivation, and loneliness were particularly detrimental. Social determinants were additive, constituting cumulative stressors that convey increased risk for young adults' mental well-being. The findings suggest that health inequality can be reduced by directly addressing its social determinants. Although important, improved access to social and mental health services alone is unlikely to relieve the burden of PD and its adverse consequences both for individual suffering and at the national level. Broader and combined policy measures are required to combat poverty and deprivation, discrimination, lack of trust, and loneliness. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Pandemic financial hardships and suicide risk in a nationally representative sample of young adults

ABSTRACT Using a nationally representative sample of young adults, this study examines COVID-induced financial hardship and its association with suicide risk (N = 1,087). About 40% experienced one or more financial hardship, a third reported having suicidal ideation, and 1.57% reported suicide attempt. The association between financial hardship and suicide risk was cumulative: Those reporting four or more financial hardships were 2.61 times more likely to report suicidal ideation and 24.27 times more likely to report a suicide attempt. The finding that COVID-related financial insecurity was associated with drastically elevated suicide risks highlights the need to assess financial hardship for suicide risk.

Tobacco Whack-A-Mole: A Consumption Taxonomy of Cigar & Other Combustible Tobacco Products among a Nationally Representative Sample of Young Adults.

Little filtered cigars and cigarillos (LCCs) are consumed infrequently, co-administered with marijuana, and concurrently used with other tobacco products. Reliance on the past 30-day use estimate, a marker of tobacco user status, may underestimate the dynamic nature of intermittent LCC and other tobacco product use. We developed a framework to capture the intermittent nature of exclusive LCC use and dual/poly use with cigarettes and large cigars using broader timing of last product use categories and product use modality (e.g., with marijuana). Data come from the baseline C'RILLOS study, a U.S. nationally representative sample of young adults aged 18-34 (n = 1063) collected in October 2019. We developed a consumption taxonomy framework that accounted for respondents' modality of LCC use (i.e., use with tobacco, LCC-T, or use with marijuana as blunts, LCC-B), the exclusive use of LCCs and other tobacco products (i.e., cigarettes, and large cigars) or their co-use and the timing of last product use (i.e., ever and past 30 days, past 3 months, past 6 months, greater than 6 months). Seventy-five percent of our sample reported ever use of any combustible tobacco product, including LCCs. The most common ever use pattern was poly use of LCC-T + LCC-B + cigarettes (16%). Our consumption taxonomy framework demonstrated the fluid nature of combustible tobacco product use among LCC users. For instance, among past 30-day cigarette users, 48% reported using LCC-T, 39% reported using LCC-B, and 32% reported using large cigars in the past 3 months or more. The tobacco use field currently classifies 'tobacco users' based on the product they smoked in the past 30 days. Any tobacco product use beyond the past 30-day period is considered 'discontinued use' and not the focus of intervention or tobacco regulatory science decisions. We documented the substantial proportion of young adult LCC, cigarette, and large cigar users who either exclusively or dual/poly used these combustible products in recent (e.g., past 3 months) periods. To prevent underestimation of use, surveillance measures should assess the use modality, timing of last product use, and exclusive/multiple product use to more accurately identify the smoking status of young adult LCC users.

Alexithymia and post-traumatic stress disorder symptoms in Chinese undergraduate students during the COVID-19 national lockdown: The mediating role of sleep problems and the moderating role of self-esteem.

This study examined whether sleep disturbance was a mediator between alexithymic traits and post-traumatic stress disorder (PTSD) COVID-19 pandemic-related stress symptoms, and explored whether self-esteem moderated the alexithymic contribution to poor sleep and PTSD symptoms. A representative sample of young adults (N = 2,485) from six universities in Southwest China completed online self-report surveys on alexithymia, sleep, PTSD, self-esteem, sociodemographic information, and health-related behaviors. High alexithymic young adults were found to be more likely to have higher sleep problems and higher PTSD symptoms. The moderated mediation model showed that sleep problems mediated the associations between alexithymia and PTSD symptoms. Alexithymic people with lower self-esteem were more likely to have elevated PTSD symptoms and sleep problems than those with higher self-esteem. Targeted psychological interventions for young people who have difficulty expressing and identifying emotions are recommended as these could assist in reducing their post-traumatic psychophysical and psychological problems. Improving self-esteem could also offer some protection for trauma-exposed individuals.

Changes in Little Cigar and Cigarillo Use during the COVID-19 Pandemic: A Cross-Sectional Analysis of a Nationally Representative Sample of Young Adult Users.

We examined the smoking behaviors of U.S. young adults ages 18–36 regarding little cigars and cigarillos (LCCs) during the COVID-19 pandemic. Survey data were collected from a nationally representative sample of young adults between October and November 2020. Respondents who reported using LCCs with tobacco (CAI) and/or with marijuana (CAB) within the past 6 months prior to the survey (n = 399) were included in the study. Logistic regression analyses assessed the association between their perceived risk of having COVID when smoking LCCs and pandemic-related behavioral changes in CAI and CAB use (e.g., worrying, quit attempts, smoking more, smoking less). Findings showed that users with a higher perceived risk of getting COVID-19 when smoking LCCs were more likely to endorse trying to quit CAI and CAB during the pandemic. Compared to the non-Hispanic White population, the non-Hispanic Black population were less likely to endorse smoking less CAI and trying to quit CAB during the pandemic. Dual users of CAI and CAB and females were more likely to endorse smoking more CAB compared to CAB-only users and males, respectively. Tailored cessation strategies are needed for dual users, non-Hispanic Black young adults, and young women. Raising awareness about the risks of LCC use can be an effective strategy for LCC smoking cessation.

Changes in Mental Health during the COVID-19 Pandemic among Representative Sample of Young Adults from Germany, Israel, Poland, and Slovenia: A Longitudinal Study.

The aim of this cross-national longitudinal study was to identify a change in mental health indicators: coronavirus-related post-traumatic stress disorder (PTSD), perceived stress, and fear of vaccination (FoVac). The first measurement (T1) took place in February 2021, and the second (T2) took place in May–June 2021. The sample consisted of 1723 participants across Germany, Israel, Poland, and Slovenia, between the age of 20 and 40 (M = 30.74, SD = 5.74). A paired-samples Student’s t-test was used for testing the differences between T1 and T2. A repeated measures two-way ANOVA was performed to examine changes over time (T) and across the countries (C). A significant although small decrease at T2 was found for coronavirus-related PTSD, perceived stress, and FoVac. A significant main effect was found for T, C, and TxC for all variables, except the interaction effect for coronavirus-related PTSD and perceived stress. A medium effect size was found for coronavirus-related PTSD and FoVac across countries as well as perceived stress over time. A small effect size was revealed for coronavirus-related PTSD and FoVac over time, perceived stress across countries, and interaction for FoVac. A significant improvement in mental health was demonstrated across the four countries (particularly in Israel); however, there were still differences among each of them. Therefore, the cross-national context should be taken into consideration when analyzing the effects of the COVID-19 pandemic on mental health.

Child socioeconomic status, childhood adversity and adult socioeconomic status in a nationally representative sample of young adults

IntroductionNumerous studies have examined the consequences of childhood adversity (CA) and socioeconomic status (SES) for health over the life course. However, few studies have examined the relation between childhood SES and CA as well as the influence of CA on adult SES. The objective of this study was to examine direct and indirect associations between childhood SES, CA and adult SES. MethodsParticipants in the National Longitudinal Study of Adolescent to Adult Health, (N = 6844) reported on nine CA experiences. Childhood SES was characterized as a composite measure of parental highest education level, median household income, and parental occupational status. Adult SES was characterized as composite measure of highest education level attained at age 37, median household income and occupation. ResultsIn mediation analyses, adjusted for age, race and sex pathways were noted in that lower child SES was associated with CAs and CAs were associated with lower adult SES. Furthermore, CAs partially mediated the relation between childhood SES and adult SES. The proportion mediated by CA was small and only noted among African-American (4%) and White participants (5%). ConclusionsChildhood SES is associated with CAs. In turn, CAs are associated with lower adult SES, independent of childhood SES supporting the notion that intervening on CAs early on in the lifecourse could influence health and wellbeing throughout the life course.

Prevalence and Sociodemographic Predictors of Mental Health in a Representative Sample of Young Adults from Germany, Israel, Poland, and Slovenia: A Longitudinal Study during the COVID-19 Pandemic

The aim of this cross-national longitudinal study was to evaluate the prevalence and sociodemographic predictors of mental health indicators (coronavirus-related post-traumatic stress disorder (PTSD), perceived stress, anxiety, depression, and suicidal/self-harm ideation) during the coronavirus disease-2019 (COVID-19) pandemic in a three-month period among representative samples of young adults from Germany, Israel, Poland, and Slovenia. The participants were 1724 young adults between 20 and 40 years of age (M = 30.74, SD = 5.74). The first measurement (T1) was in February 2021 and the second (T2) was in May–June 2021. The samples were representative of young adults in each country: Germany (n = 418, 24%), Israel (n = 428, 25%), Poland (n = 446, 26%), and Slovenia (n = 431, 25%). Women constituted 54% (n = 935) of the total sample. The mental health indicators were coronavirus-related PTSD measured by PCL-S, perceived stress (PSS-10), anxiety (GAD-7), depression (PHQ-8), and suicidal ideation (PHQ-9). The participants completed an online questionnaire that also included a physical activity (PA) measurement and sociodemographic variables. The Pearson’s χ2 independence test was used for prevalence comparisons and McNemar’s χ2 was used for longitudinal changes, whereas generalized estimating equations (GEEs) were used for the predictors of change in mental health indices. Significant differences were found between countries in each mental health dimension in both T1 and T2, with moderate effect sizes for coronavirus-related PTSD and suicidal ideation. The highest rate of PTSD and depression risk was in Germany, the highest rates of stress and anxiety risk were in Poland, and there was insufficient PA in Slovenia. The anxiety, depression, and suicidal ideation rates were the lowest in Israel and Slovenia. Israeli participants reported the lowest rate of coronavirus-related PTSD among the other countries in T1 and T2. Significant decreases in coronavirus-related PTSD and stress were observed during T2 compared to T1 in the total sample. There was no change in the risk of anxiety, depression, or suicidal ideation. Being single was a predictor of changes in all mental health indices. Having children was a risk factor for coronavirus-related PTSD and high stress. Being a student was a predictor of depression and suicidal ideation. A younger age (20–29 years) predicted coronavirus-related PTSD risk, whereas female gender predicted high stress. The mental health indices improved over time or remained stable. The groups that are most prone to mental health problems were single individuals, students, and parents in young adulthood across all countries. Future intervention programs for young adults should consider these factors when prioritizing, planning, and implementing such programs.

Young adults with nonalcoholic fatty liver disease, defined using the fatty liver index, can be at increased risk of myocardial infarction or stroke.

To investigate the relationship between nonalcoholic fatty liver disease (NAFLD) and cardiovascular events among a nationally representative sample of young adults in Korea. This population-based cohort study from the Korean National Health Insurance Service included adults who were aged 20 to 39 years when they underwent a health examination between 2009 and 2012. NAFLD was defined as a fatty liver index (FLI) ≥60, and participants were divided into three groups according to FLI (<30, 30-59 and ≥60) to investigate the dose-dependent effect of FLI score. Among 5 324 410 participants, 9.8% had an FLI ≥60. There were 13 051 myocardial infarctions (MIs; 0.39%) and 8573 strokes (0.26%) during a median follow-up of 8.4 years. In multivariable analysis, NAFLD was associated with a higher risk of MI and stroke (hazard ratio [HR]1.69, 95% confidence interval [CI] 1.61-1.77 and HR1.73, 95% CI 1.63-1.84, respectively). MI and stroke had dose-dependent relationships with FLI (HR1.28 in participants with FLI 30-59 and 1.73 in those with FLI ≥60 for MI and HR1.18 in participants with FLI 30-59 and 1.41 in those with FLI ≥60 for stroke, respectively). Nonalcholic fatty liver disease was an independent predictor of MI and stroke in young adults. These results suggest that primary prevention of cardiovascular disease should be emphasized in young adults with NAFLD.

A psychometric analysis of the Daily Drinking Questionnaire in a nationally representative sample of young adults from a Mediterranean drinking culture

Aims: To examine psychometric properties of the Daily Drinking Questionnaire (DDQ) in a Mediterranean “wet” drinking culture. Methods: Three studies were conducted using random samples drawn from a representative sample of Italian young adults (N = 5,955; females = 62%; mean age = 27): Study 1 explored the factorial structure of weekly alcohol consumption; in Study 2 multi-group confirmatory factor analysis tested measurement invariance across gender; Study 3 applied item response theory analysis to: a) assess how each item discriminated between different alcohol consumption levels; and b) determine if drink propensity on a given day of the week varied according to individual characteristics. Results: In Study 1, a one-factor solution with no clear differentiation between weekdays and weekend alcohol use was found. Study 2 confirmed measurement invariance of the one-factor solution across gender. Results of Study 3 indicated that alcohol use on weekdays (Monday to Thursday) provided more information on overall alcohol consumption than alcohol use on weekends (Friday to Sunday). Discussion: Cultural differences of alcohol use are reflected in relatively simple alcohol measures, such as the DDQ. In contrast with peers from “dry” drinking cultures, Italian young women and men do not clearly differentiate between weekdays and weekend drinking. In Italy, the DDQ best captures participants' average alcohol consumption levels rather than light or heavy, and should be used in national epidemiological research accordingly.

Exposure to E-Cigarette Product Placement in Music Videos Is Associated With Vaping Among Young Adults.

The prevalence of electronic-cigarette (e-cigarette) product placement in music videos is on the rise and currently unregulated. This promotional activity is concerning given the popularity of music videos among young adults. We examined associations between self-reported levels of exposure to music videos with any e-cigarette product placement or imagery and susceptibility to use e-cigarettes and e-cigarette use. A representative sample of young adults (18-24 years of age), residing in California (n = 1,280), completed online surveys assessing self-reported exposure to music videos with e-cigarette product placement or imagery and susceptibility to use e-cigarettes and e-cigarette use. Adjusted and weighted regression analyses were used for statistical analyses. Participants exposed to any e-cigarette product placement or imagery in music videos were more likely to report lifetime e-cigarette use (relative risk ratio [RRR]: 2.81) and past 30-day use (RRR: 3.64) compared with participants with no exposure. Additionally, participants with greater levels of exposure were more likely to report lifetime e-cigarette use (RRR: 1.13) and past 30-day use (RRR: 1.20) compared with participants with lower levels of exposure. Among those with any exposure, participants younger than 21 years of age (i.e., under the tobacco purchasing age in the United States) were more likely to report lifetime e-cigarette use (RRR: 4.68) compared with those aged 21 years and older. Restricting e-cigarette product placement or imagery in music videos may minimize marketing exposure and risk for vaping among young adults, especially among those under the tobacco purchasing age.

Local variation in cannabis use patterns among young adults in the San Francisco Bay Area

This study evaluated whether neighborhood-level disorder, social cohesion, and perceived safety, were associated with days of cannabis use in the prior month in a representative sample of young adults in Alameda and San Francisco Counties in California (N = 1272). We used multiscale geographically weighted regression, modeled by county, to measure associations between cannabis use days and neighborhood attributes, adjusting for sociodemographic characteristics and self-rated health. Positive associations were found between number of cannabis use days and neighborhood disorder, and greater perceived safety. Higher levels of social cohesion predicted fewer cannabis use days. Racial/ethnic, sex and, socioeconomic compositions of participants residing in areas with significant neighborhood-level associations varied substantially, suggesting that risk factors for young adult cannabis use may be highly localized. Public health efforts in cannabis education and intervention should be tailored to fit the culture and composition of local neighborhoods.

Predicting suicidal ideation in a nationally representative sample of young adults: a 12-month prospective study.

Evidence-based theoretical models outlining the pathways to the development of suicidal ideation may inform treatment. The current research draws from the Interpersonal Theory of Suicide (IPT) and the Integrated Motivational-Volitional (IMV) Model of suicidal behaviour and aims to test the interaction between perceived burdensomeness and thwarted belongingness as proposed by the IPT model, and the defeat-entrapment pathway as proposed by the IMV model, in the prediction of suicidal ideation at 12-month follow-up. The Scottish Wellbeing Study is a nationally representative prospective study of young people aged 18-34 years (n = 3508) from across Scotland, who completed a baseline interview and a 12-month follow-up (n = 2420). The core factors from both the IPT (perceived burdensomeness and thwarted belongingness) and the IMV model (defeat, internal and external entrapment) were measured alongside demographics, depressive symptoms and suicidal ideation at baseline. At 12-month follow-up, suicidal ideation was assessed again. In multiple regression analysis perceived burdensomeness and internal entrapment, with baseline suicidal ideation, predicted 12-month suicidal ideation. No support for the interaction between perceived burdensomeness and thwarted belongingness in predicting 12-month suicidal ideation was found. However, there was evidence that internal, but not external, entrapment mediated the relationship between defeat and 12-month suicidal ideation, but no support was found for the moderation of burdensomeness and belongingness on the entrapment to suicidal ideation pathway. The current findings highlight the importance of targeting perceived burdensomeness and internal entrapment to reduce the likelihood that suicidal ideation emerges in at risk individuals.

Early origins of socioeconomic inequalities in chronic inflammation: Evaluating the contributions of low birth weight and short breastfeeding.

The United States is characterized by persistent and widening social inequities in a wide range of adult health outcomes. A life course approach challenges us to consider if, and how, these inequities trace back to early life conditions, and chronic inflammation represents a potentially important mechanism through which early environments may have lasting effects on health in adulthood. Low birth weight (LBW) and shorter durations of breastfeeding both predict increased inflammation in adulthood, which is associated with increased risk for cardiovascular disease, metabolic syndrome, and all-cause mortality. Using data from a large representative sample of young adults in the US (National Longitudinal Study of Adolescent to Adult Health (Add Health)), we document the socioeconomic status (SES) gradient in chronic inflammation, as indicated by concentrations of C-reactive protein (CRP). Using a nested set of structural equation models and marginal standardization techniques, we investigate the extent to which this gradient is explained by patterns of LBW and breastfeeding in infancy. Findings reveal a particularly important role for breastfeeding duration: Based on model predictive margins, increasing breastfeeding duration to three or more months corresponds to a flattening of the SES gradient by 80%, and 83% when LBW is eliminated. This study expands current understandings of the consequential role of developmental environments for population health and for addressing health inequities in future generations.
