ABSTRACT
BACKGROUND: Young adults in the United States, including college students, have the highest prevalence of cannabis use compared with other age groups. Although cannabis vaping is increasingly prevalent during young adulthood, little is known about factors contributing to the onset of cannabis vaping during this developmental period. METHODS: Participants were 3085 cannabis vaping naïve young adults aged 18-25 years (M = 20.60; SD = 1.80), initially recruited from 24 Texas colleges and participating in a multi-wave, longitudinal study. A survival analysis was conducted to determine if participants reporting elevated depressive symptoms had an increased risk of onset of cannabis vaping over six follow-up waves from fall 2015 to spring 2019 compared to their peers with lower levels of depressive symptoms. Socio-demographic characteristics, time-varying past 30 day substance use, and time-varying peer nicotine vaping were included as covariates in the model. RESULTS: Twenty-five percent of participants initiated cannabis vaping during the four-year study period, with stable initiation rates from 2015 to 2017 but doubling from 2017 to 2019. Analyses, both unadjusted and adjusted for study covariates, indicated that elevated depressive symptoms were significantly associated with an increased risk of cannabis vaping initiation. CONCLUSION: Findings indicate that initiation of cannabis vaping during young adulthood is common, and particularly more likely among those with greater depressive symptoms, thus underscoring the importance of prevention programs that include mental health support services tailored to young adults.

Cannabis use is common in young adulthood, yet little is known about the prevalence and patterns of multi-modal (i.e., use of more than one mode) cannabis use. Objective: We aimed to (1) determine the past 30-day prevalence of five modes (smoke, vape, edible, dab, other) of cannabis use, (2) describe the prevalence of multi-modal cannabis use (single vs. dual vs. poly-modal), and (3) identify socio-demographic correlates of multi-modal use among young adults. Method: Participants were 764 22-30-year-olds who currently used cannabis from Wave 9 (Spring 2019) of the Marketing and Promotions Across Colleges in Texas Project. Participants were 25.11 years old on average (SD = 1.81), 63.6% female, 38.7% identified as non-Hispanic white, 30.6% as Hispanic/Latino, 13.0% as Asian and 9.4% as Black, and 8.2% identified with two or more races or another race/ethnicity. Bivariate analyses and a multinomial regression were used to examine study questions. Results: Smoking was the most common mode of cannabis use followed by vaping and then edibles. Nearly 43% of participants reported single-modal cannabis use, 33% reported dual-modal use, and 24% reported poly-modal use. Males and those identifying as non-heterosexual were at a greater risk than their counterparts for using multiple modes of cannabis. Participants identifying as Black were at a reduced risk for poly-modal compared to single-modal use. Conclusion: Multi-modal use is common among young adults who currently use cannabis, indicating a need for universal efforts aimed at all young adults. Tailored interventions aimed toward those at elevated risk for multi-modal use also are needed.
ABSTRACT
INTRODUCTION: Sugar-sweetened beverage and caffeinated beverage consumption are associated with a variety of health issues among youth. Food and beverage marketing has been shown to affect youth's preferences, purchases, and consumption of marketed products. Previous research suggests that outdoor food and beverage marketing differs by community demographics, with more advertisements in lower-income communities and near schools. The purpose of this study is to examine the density of sugar-sweetened and caffeinated beverage advertisements near schools by school type (middle vs. high school) and by school-level SES. METHODS: Data are from the Outdoor Measuring and Evaluating the Determinants and Influence of Advertising (MEDIA)study, which documented and described all outdoor food and beverage advertisements near 47 middle and high schools in 2012. Beverage advertisements were categorized as: sugar-sweetened/caffeinated, sugar-sweetened/non-caffeinated, non-sugar-sweetened/caffeinated, or non-sugar-sweetened/non-caffeinated. Schools were categorized by type (middle vs high) and by SES as determined by the percentage of students qualifying for free or reduced-price lunch. Bootstrapped non-parametric Mann-Whitney U tests compared the number of advertisements in each category by school type and school-level SES (higher vs lower). RESULTS: Compared to schools with higher SES, schools with lower SES had significantly more advertisements for sugar-sweetened/non-caffeinated beverages (Medianlow = 28.5 (IQR 17-69), vs Medianhigh = 10.5 (IQR 4-17) (p = 0.002)., sugar-sweetened non-caffeinated (Medianlow = 46 (IQR 16-99) vs Medianhigh = 13.5 (IQR 6-25), p = 0.002), -sugar-sweetened caffeinated (Medianlow = 12 (IQR 8-19) vs Medianhigh = 6 (IQR 2-8), p = 0.000), and non-sugar-sweetened non-caffeinated (Medianlow = 30 (IQR 13-65) vs Medianhigh = 14 (IQR 4-29), p = 0.045).There were no significant differences by school type. CONCLUSION: This study adds to the literature demonstrating pervasive marketing of unhealthy products in lower-income communities. Disproportionate exposure to sugar-sweetened and caffeinated beverage advertisements in lower-income communities may contribute to the disparities in associated health outcomes by economic status.

Little research has examined the new onset of cigarette and Electronic Nicotine Delivery System (ENDS) dependence symptoms among young adults. This study aims to 1) examine new onset cigarette and ENDS dependence symptoms over a 4.5-year period and 2) examine how depressive symptoms impact new onset dependence symptoms among young adults. Participants were drawn from 24 colleges in Texas who were participating in a multi-wave cohort study (2014-2019). The present study included 4536 participants aged 18-25 who did not report cigarette or ENDS dependence symptoms at wave 1 (64.1% female; 65.2% non-white; m age = 20.62 [SD = 1.80] at wave 1). Cox's regression models were employed to determine the hazard of new onset cigarette and ENDS dependence symptoms overall and the impact of depressive symptoms. Models controlled for sociodemographic factors and other tobacco product use. 14.4% of participants reported new onset cigarette dependence symptoms and 14.6% reported new onset ENDS dependence symptoms over the 4.5 years of the study. Depressive symptoms significantly predicted increased risk for new onset cigarette (HR = 1.30, CI = [1.21, 1.39]) and ENDS (HR = 1.20, CI = [1.12, 1.29]) dependence symptoms. Young adults exhibited dependence symptoms for cigarettes and ENDS products at similar rates across the 4.5 years of the study. Elevated depressive symptoms increased risk of new onset cigarette and ENDS dependence symptoms, advancing evidence for the self-medication hypothesis. Tobacco and nicotine prevention and cessation programs and messaging are needed particularly among young adults who experience depressive symptoms.

We examined if areas around schools with more students of lower socioeconomic status (SES) have more total food/beverage advertisements and/or more advertisements with poorer nutritional content as compared to areas around schools with fewer students with lower SES. All outdoor food/beverage advertisements within a half-mile radius of 47 middle and high schools in the United States were objectively documented in 2012 and coded for nutritional content. The total number of advertisements and the macronutrient and micronutrient contents (total calories, fat (g), protein (g), carbohydrate (g), sugar (g), and sodium (mg)) of food and beverage items depicted in the advertisements were calculated. In total, 9132 unique advertisements were recorded, with 3153 ads displaying food and beverages that could be coded for nutrient content. Schools located in areas of lower SES (≥60% students receiving free/reduced-price lunch) had significantly more advertisements displaying food and beverages that could be coded for nutrient content (z = 2.01, p = 0.04), as well as advertisements that contained more sodium (z = 2.20, p = 0.03), as compared to schools located in areas of higher SES. There were no differences in calorie, fat, protein, carbohydrate, or sugar content. Policies to reduce the prevalence of outdoor food and beverage advertising are warranted.

INTRODUCTION: While tobacco retail outlet (TRO) marketing exposure has been associated with tobacco use, little research has explored how this relationship may vary by the experience of depressive symptoms. The purpose of this study was to examine if the relationship between TRO tobacco marketing exposure and tobacco use initiation is moderated by depressive symptoms among young adults. METHODS: Participants were drawn from 24 colleges in Texas who were participating in a multi-wave cohort study (2014-2019). The present study included 2020 cigarette or ENDS naïve participants at wave 2 (69.2% female; 32.1% white; m age=20.6 [SD=2.0] at wave 1). Generalized mixed-effects logistic regression analyses were used to examine the association between cigarette and ENDS TRO marketing exposure and subsequent initiation for both products with depressive symptoms as a moderator. RESULTS: The interaction between cigarette marketing and depressive symptoms was significant (OR=1.38 95% CI=[1.04,1.83]). Cigarette marketing did not impact cigarette initiation among participants with low depressive symptoms (OR=0.96 95% CI= [0.64,1.45]), but did impact cigarette initiation among participants with high depressive symptoms (OR=1.83 95% CI=[1.23,2.74]). There was no interaction effect for ENDS initiation. Main effects showed that ENDS marketing exposure predicted ENDS initiation (OR=1.43 95% CI=[1.10,1.87]). CONCLUSIONS: Exposure to tobacco marketing at TROs is an important risk factor for initiation of cigarette and ENDS use, particularly for cigarette initiation among those who experience greater levels of depressive symptoms. Future work is needed to better understand why this type of marketing is influential for this group.

Background:Evidence suggests that health literacy, perceived availability of information and guidance to adapt to challenges (informational support), and symptoms of depression all have the potential to mediate or moderate the relationship between patient-rated involvement in decisions and satisfaction with care. If so these could be useful targets for improving patient experience. Methods: We prospectively enrolled 130 new adult patients visiting an orthopedic surgeon over a 4-month period. All patients were asked to complete measures of satisfaction with care (21-item Medical Interview Satisfaction Scale), perceived involvement in decisions (9-item Shared Decision-Making Questionnaire), symptoms of depression (the Patient-Reported Outcomes Measurement Information Scale [PROMIS] Depression Computerized Adaptive Test [CAT]), perceived availability of information and guidance to adapt to challenges (PROMIS Informational Support CAT), and the Newest Vital Sign test of health literacy. Results: The strong correlation between satisfaction with care (ρ = 0.60, P < .001) and perceived involvement in decisions was neither mediated nor moderated by health literacy, perceived availability of information and guidance, and symptoms of depression. Conclusions: The observation that patient-rated shared decision-making is strongly related to satisfaction with an office visit, independent of health literacy, perceived support, and symptoms of depression, is consistent with evidence that various measures of patient experience tend to correlate and emphasizes the importance of the patient-clinician relationship. Level of Evidence: Level II, prospective study.
ABSTRACT
OBJECTIVE: The relative association of pain intensity and magnitude of incapability with pathophysiology, accounting for psychological factors, is incompletely understood. Using moderation analysis, we assessed the association of pain intensity and magnitude of incapability (dependent variables) with fracture severity (independent variable) and the influence of symptoms of depression and catastrophic thinking (moderators) at early and later stages of recovery. METHODS: A cohort of 731 patients recovering from a shoulder, elbow, or wrist fracture, completed self-reported measures of pain intensity, upper extremity capability, symptoms of depression, and catastrophic thinking between 2 and 4 weeks after injury and again between 6 and 9 months after injury. Fracture severity was rated by clinicians, and we used multivariable regression analysis to examine interaction effects of fracture severity, depression, catastrophic thinking, pain intensity, and magnitude of incapability at early and later stages of recovery. RESULTS: Symptoms of depression and catastrophic thinking attenuate the relationship between pain intensity and fracture severity at earlier and later stages of recovery. Symptoms of depression and catastrophic thinking also attenuate the relationship between the magnitude of incapability and fracture severity, but only at early stages of recovery. CONCLUSION: The relative divergence of pain intensity and magnitude of incapability from the level of fracture severity due to the moderating effects of unhelpful thinking and distress, signals a benefit to anticipating mental health opportunities during recovery after fracture. Fracture management can incorporate measures of unhelpful thinking and symptoms of distress to better address these opportunities and ensure comprehensive optimization of recovery. LEVEL OF EVIDENCE: Level IIc, prognostic.

INTRODUCTION: Research has demonstrated disparities in depressive symptoms among people who are marginalized. However, more work should examine depressive symptoms through an intersectional lens, recognizing that multiple systems of privilege and oppression interlock to create unique struggles where multiple marginalized identities meet. Recent methodological developments have advanced quantitative intersectionality research using multilevel modeling to partition variance in depressive symptoms to person-level sociodemographic variables and intersectional-level social strata. The purpose of this study is to leverage these methods to examine trajectories of depressive symptoms among young adults in Texas through an intersectional lens. METHODS: Multilevel modeling was used to examine the longitudinal trajectories of depressive symptoms among 3575 young adults from 24 colleges in Texas assessed seven times between Fall 2014 and Spring 2018. Intersectional identities included sex, race/ethnicity, and sexual and gender minority identities. The model examined time nested within individuals and individuals nested within intersectional social strata. RESULTS: Young adults in Texas experienced an increase in depressive symptoms from 2014-2018. Those with female, Hispanic, AAPI, other race/ethnicity, or LGBTQ + identities experienced more depressive symptoms. After controlling for the main effects of the sociodemographic variables, 0.08% of variance in depressive symptoms remained attributed to the effects of intersectional identities. CONCLUSION: Evaluating disparities in depressive symptoms through an intersectional lens offers a more complete description of the epidemiology of depressive symptoms. Communities and institutions that serve marginalized people should consider the elevated burden of depressive symptoms that marginalized people may carry, and integrate culturally competent psychoeducation, assessments, and therapies where possible.

INTRODUCTION: Due to medical advances, care for patients that experience burns has shifted from saving life to improving quality of life. Reintegrating into the community and maintain body image satisfaction may be difficult after a severe burn. Several studies have analyzed these two variables independently, but none have addressed a potential interrelationship. AIM: To investigate the indirect or direct relationship of body image and community integration, potentially mediated or moderated by social stigma, symptoms of depression, symptoms of post-traumatic stress disorder (PTSD), or posttraumatic growth. METHODS: Data from the Burn Models Systems (BMS) Database between the years 2014 and 2020, patients who were at least 18 years of age and who had completed questionnaires that measured body image satisfaction, attitudes of community integration, perceived social stigma, and symptoms of depression, symptoms of PTSD, and posttraumatic growth were used to analyze potential mediators and moderators of the relationship between body image and community integration using multivariable linear regression models and structural equation modeling. RESULTS: Social stigma, symptoms of depression, and symptoms of PTSD were determined to completely mediate the association of body image and community integration. Posttraumatic growth did not mediate this association. Social stigma, symptoms of depression, symptoms of PTSD, and posttraumatic growth did not moderate the relationship between body image and community integration. CONCLUSION: The finding that symptoms of distress and social stigma account for the relationship between body image satisfaction and community integration support the potential for interventions that ameliorate distress to improve community integration and quality of life in people recovering from burn injuries.

BACKGROUND: Given the relationship between psychological distress and activity tolerance (capability), a stressful life event might diminish accommodation, increase symptoms, and induce a person to seek specialty care. As a first step to investigate this possibility, this study addressed whether difficult life events are associated with greater activity intolerance and pain intensity. METHODS: A cohort of 127 patients seeking specialty care for lower extremity symptoms completed questionnaires that inquired about difficult life events within the last 12 months as derived from the Holmes Rahe Life Stress Inventory, and recorded pain intensity on an 11-point ordinal scale, activity tolerance [Patient Reported Outcomes Measurement Information System Physical Function Computer Adaptive Test (CAT)], symptoms of anxiety (GAD-2; 2 item version of the Generalized Anxiety Disorder questionnaire), symptoms of depression (PROMIS Depression CAT), self-efficacy when in pain (Pain Self-Efficacy Questionnaire, 2 question version), and demographics. The treating clinician indicated if the disease was established (e.g. arthritis) or relatively new (e.g. sprain/strain). Bivariate and multivariable analyses sought factors associated with activity intolerance and pain intensity. RESULTS: Greater activity intolerance was associated with difficult life events in bivariate analyses (t = 2.13, MD = 3.18, 95% C.I. = 0.22-6.13, p = 0.04) and in multivariable analyses that excluded symptoms of depression. Greater pain intensity was not associated with difficult life events, but was associated with surgeon rating of established disease (ß = 1.20, 95% C.I. = 0.33-2.08, p < 0.01), greater symptoms of anxiety (MD = 3.35, s = 1.72; ρ = 0.30, p < 0.01), and less education (ß = - 1.06, 95% C.I. = - 1.94- - 0.18, p = 0.02) (no college degree). CONCLUSION: When a musculoskeletal specialist identifies less activity tolerance (less capability) than anticipated for a given injury or pathology, they can anticipate a potential difficult life event, and expect alleviation of symptoms and improved capability as the stress is ameliorated with time and support. Specialists can be prepared to direct people to community or professional support if requested.

Mitochondria modulate inflammatory processes in various model organisms, but it is unclear how much mitochondria regulate immune responses in human blood leukocytes. Here, we examine the effect of i) experimental perturbations of mitochondrial respiratory chain function, and ii) baseline inter-individual variation in leukocyte mitochondrial energy production capacity on stimulated cytokine release and glucocorticoid (GC) sensitivity. In a first cohort, whole blood from 20 healthy women and men was stimulated with increasing concentrations of the immune agonist lipopolysaccharide (LPS). Four inhibitors of mitochondrial respiratory chain Complexes I, III, IV, and V were used (LPS + Mito-Inhibitors) to acutely perturb mitochondrial function, GC sensitivity was quantified using the GC-mimetic dexamethasone (DEX) (LPS + DEX), and the resultant cytokine signatures mapped with a 20-cytokine array. Inhibiting mitochondrial respiration caused large inter-individual differences in LPS-stimulated IL-6 reactivity (Cohen's d = 0.72) and TNF-α (d = 1.55) but only minor alteration in EC50-based LPS sensitivity (d = 0.21). Specifically, inhibiting mitochondrial Complex IV potentiated LPS-induced IL-6 levels by 13%, but inhibited TNF-α induction by 72%, indicating mitochondrial regulation of the IL-6/TNF-α ratio. As expected, DEX treatment suppressed multiple LPS-induced pro-inflammatory cytokines (IFN-γ, IL-6, IL-8, IL-1ß, .TNF-α) by >85% and increased the anti-inflammatory cytokine IL-10 by 80%. Inhibiting Complex I potentiated DEX suppression of IL-6 by a further 12% (d = 0.73), indicating partial mitochondrial modulation of glucocorticoid sensitivity. Finally, to examine if intrinsic mitochondrial respiratory capacity may explain a portion of immune reactivity differences across individuals, we measured biochemical respiratory chain enzyme activities and mitochondrial DNA copy number in isolated peripheral blood mononuclear cells (PBMCs) from a second cohort of 44 healthy individuals in parallel with LPS-stimulated IL-6 and TNF-α response. Respiratory chain .function, particularly Complex IV activity, was positively correlated with LPS-stimulated IL-6 levels (r = 0.45, p = 0.002). Overall, these data provide preliminary evidence that mitochondrial behavior modulates LPS-induced inflammatory cytokine signatures in human blood.
ABSTRACT
Patient-reported experience measures have notable ceiling effects which can hinder efforts to learn and improve. This study tested whether an iterative (Guttman-style) satisfaction questionnaire combined with instructions intended to give people agency to critique us primes responses on an ordinal scale and reduces ceiling effects. Among the 161 subjects randomly assigned to complete an iterative satisfaction questionnaire before or after an ordinal scale, there was no difference in mean satisfaction (no priming). The Guttman scale was more normally distributed and had slightly less ceiling effect when compared to the ordinal scale. Iterative satisfaction scales partially mitigate ceiling effects. The absence of priming suggests that attempts to encourage agency and reflection have limited ability to reduce ceiling effects, and alternative approaches should be tested.
