Late Bedtime and Altered Diurnal Axial Length Rhythms of the Eye

Purpose Affecting one-third of the population worldwide and increasing, the sight-threatening condition myopia is causing a significant socio-economic burden. To better understand its etiology, recent studies investigated the role of ocular and systemic rhythms, yet results are conflicting. Here we profiled 24-h variations of axial length of the eye and salivary melatonin concentration in young adults with and without myopia and explored the potential impacts of bedtime on these rhythms. Methods A total of 25 healthy young adults (age 25.0 ± 4.8 years, 13 females) completed this study, including 13 myopes (mean spherical equivalent refractive error −2.93 ± 1.46 diopters) and 12 non-myopes (0.14 ± 0.42 diopters). Saliva sample collection and axial length measurements were repeated for seven times over 24 h starting from 8 am. Information on sleep and chronotype was collected at first visit with the Pittsburgh Sleep Quality Index and the Morningness-Eveningness Questionnaire. Results Significant diurnal rhythms of axial length and salivary melatonin concentration were identified in both refractive groups (both p < 0.001), with no myopia-related rhythm difference (interaction of measurement time-point × myopia, p = 0.9). Late bedtime was associated with altered rhythms (p = 0.009) and smaller diurnal change (p = 0.01) in axial length. Elevated melatonin levels were observed in myopes (p = 0.006) and in late sleepers (p = 0.017). Conclusions These findings suggest that sleep/wake cycles may be involved in the regulation of axial length rhythms. Further research is needed to determine if there exists a causal relationship between the two.

Similarities and differences in the functions of non-suicidal self-injury (NSSI) across gender non-conforming and cisgender young adults

BackgroundNon-suicidal self-injury (NSSI) can be motivated by a broad range of functions and many individuals report multiple reasons for self-injuring. Most NSSI research has involved predominantly female samples and few studies have examined gender similarities and differences in function endorsement. MethodsWe characterise the prevalence and versatility of NSSI functions within a gender-diverse online sample of cisgender women (cis-women; n = 280), cisgender men (cis-men; n = 176), and transgender, non-binary, and other gender non-conforming young adults (TGNC; n = 80) age 18–30 (M = 23.73, SD = 3.55). The Ottawa Self-Injury Inventory (OSI-F) assessed 24 intrapersonal and social functions across nine domains: affect regulation, self-punishment, anti-dissociation, anti-suicide, sensation seeking, sexuality, interpersonal influence, and body image. ResultsTGNC participants and cis-women were significantly more likely to report intrapersonally motivated NSSI and greater function versatility than cis-men. Low mood, emotional distress, suicidality, and trauma symptomology appeared to contribute to gender differences in function endorsement. Gender similarities also emerged; across groups, intrapersonal functions were substantially more common than social functions, and the most endorsed domains were affect regulation and self-punishment. No domains were gender specific. LimitationsThe OSI-F was developed from majority female samples and may not adequately capture the experiences of other gender groups. ConclusionsInterventions which reduce distress and strengthen emotion regulation are likely to benefit individuals who self-injure regardless of gender. However, most individuals report multiple NSSI functions and person-centred interventions which address this complexity are needed. Future research should develop gender-informed treatment models which consider the unique experiences of TGNC individuals and cis-men who self-injure.

Does stress compromise fruit and vegetable intake? A randomized controlled trial testing a model with planning as a mediator and stress as a moderator

ObjectiveIndividuals experiencing higher stress levels tend to consume fewer fruits and vegetables compared to their less stressed counterparts. Thus, to promote fruit and vegetable (FV) consumption, action planning has been proven effective in translating behavioral intentions into actual dietary behaviors. This study aims to evaluate a 7-day intervention designed to improve FV planning and intake, while also examining the role of stress. MethodsThe trial employed a 3 (time: pretest, post-test, and follow-up) * 2 (group: intervention vs. control) between-participant factorial design. A total of 99 young Chinese adults (age = 23.84 years ± 4.63, 26 men) who had formed an explicit intention to consume more fruit and vegetables, participated in a 7-day online randomized controlled trial. ResultsThe intervention successfully enhanced FV planning as well as FV intake. Furthermore, a moderated mediation model revealed that FV planning mediated the relationship between experimental conditions and FV intake, with stress moderating this mediation. Specifically, planning facilitated FV intake for individuals with low stress levels, while this effect was not observed for those with high stress levels. ConclusionThese findings confirm the positive impact of the planning intervention on improving FV intake, particularly for individuals with low stress levels, and highlight stress as a barrier to health behavior change that warrants further attention in future studies.

Effectiveness and Tolerability of Anti-Calcitonin Gene-Related Peptide Therapy for Migraine and Other Chronic Headaches in Adolescents and Young Adults: A Retrospective Study in the USA.

This retrospective study assesses the efficacy and tolerability of anti-calcitonin gene-related peptide (anti-CGRP) therapy in adolescents and young adults (ages 12-21) with migraine and chronic daily headaches unresponsive to standard treatments. Migraines in this demographic significantly impair school performance, self-esteem, psychological well-being, and cognitive health. These young patients are also particularly sensitive to the side effects of conventional medications, which are often prescribed off-label and come with high insurance denial rates. Medication overuse, including analgesics, triptans, and NSAIDs, is prevalent due to treatment failures. Elevated plasma CGRP levels observed during migraines suggest that anti-CGRP therapies, successful in adult populations, may also benefit this younger age group. Over a three-year period, patients at a specialized pediatric headache center were evaluated for the impact of anti-CGRP treatments, including monoclonal antibodies (erenumab, fremanezumab, and galcanezumab) and small-molecule CGRP receptor antagonists (ubrogepant, rimegepant, and atogepant), administered either alone or in combination with OnabotulinumtoxinA. Data were extracted from the hospital's electronic medical records, and patient progress was consistently documented using a structured template for each clinic visit. Additional patient satisfaction data were collected via telephone follow-ups and patient message reviews. The study included 23 patients, primarily treated for chronic migraine (CM) (78.3%), with a smaller subset addressing episodic migraine (EM), new daily persistent headaches (NDPHs), and post-traumatic headaches (PTHs). Comprehensive demographic and clinical data, including age, treatment duration, history of preventive treatment failures, and comorbidities like psychiatric conditions and sleep disorders, were collected. Anti-CGRP therapies, particularly when combined with traditional treatments or OnabotulinumtoxinA, resulted in significant improvements: 91.3% of patients experienced reduced migraine duration and intensity, 82.6% reported improvements in other bothersome symptoms, and 73.9% saw an improved response to rescue medications. Additionally, 78.3% of patients reported a reduction in their use of rescue medications per week by more than 50%, and emergency room visits were reduced for 56.5% of patients. Significant reductions in headache days were observed in 82.6% of patients after one month and 87% after three months, with nearly 40% experiencing more than a 50% reduction in both periods. The greatest benefits were observed in patients treated for more than six months. Adverse effects were minimal, with 95.7% of patients reporting no side effects, and patient satisfaction was high, with 69.6% opting to continue treatment. Overall, this study highlights the substantial potential of anti-CGRP therapy in improving outcomes for adolescents and young adults with CM and EM, offering a promising approach for a demographic that faces considerable challenges with conventional treatment options. However, further research is needed to confirm these findings and expand clinical applications in this age group.

Distribution of endometriosis phenotypes according to patients' age in adult women with surgical evaluation.

What is the distribution of endometriosis phenotypes according to age in adult women undergoing surgery? The phenotype of endometriosis did not significantly vary after 24 years old. The phenotypic evolution of endometriosis over time remains unclear. While adolescents can exhibit any type of endometriosis lesions, ovarian endometriosis (OMA) and/or deep-infiltrating endometriosis (DIE) tend to increase with age in young adults. In adulthood, understanding the evolution of lesions is crucial for disease management, but the literature on this subject is limited. This study aims to examine the distribution of endometriosis phenotypes in relation to age among adult patients requiring surgical treatment. This observational cohort study included patients aged between ≥18 and ≤42 years, who underwent surgery for benign gynecological conditions at our institution between January 2004 and December 2022. A standardized questionnaire was completed for each patient during a face-to-face interview conducted by the surgeon in the month preceding surgery. Women with histologically proven endometriosis were included. The distribution of endometriosis phenotypes (isolated superficial (SUP) endometriosis, OMA ± SUP, DIE ± SUP/OMA) was compared between young adults (≤24 years) and adults (>24 years) and among adults (25-28 years, 29-33 years, 34-38 years, 39 to ≤42 years) using univariate and multivariate analysis. The distribution of different subtypes of DIE (uterosacral ligament(s), vagina, bladder, intestine, and ureter), OMA size, and intensity of pain symptoms were also examined. A total of 1311 adult women with histologically proven endometriosis were included. In women aged 24 years or younger (n = 116), the distribution of endometriosis phenotypes differed significantly from women older than 24 years (n = 1195): The frequency of the DIE ± SUP/OMA phenotype was lower (41.4% versus 56.1%, respectively), while the rate of isolated superficial lesions was higher (from 32.0% versus 25.9%) (P = 0.001). In the group of women aged >24 years, a significantly higher proportion of vaginal DIE lesions (P = 0.012) and a lower proportion of uterosacral ligament DIE lesions (P = 0.004) were found compared to women aged ≤24years. No significant differences were observed in terms of endometrioma size. Between the ages of 25 and 42years, there were no significant changes in the distribution of endometriosis phenotypes after univariate and multivariate analysis. The distribution of subtype of DIE lesions did not significantly change with age between 25 and 42 years. Concerning pain symptom scores, there was a significant decrease with age for dysmenorrhea and dyspareunia. Inclusion of only surgical patients may have introduced a selection bias. Women referred to our center may have suffered from particularly severe clinical forms of endometriosis. This study highlights that endometriosis presentation did not change with age in adult women. Further research on endometriosis phenotype evolution is necessary to assist practitioners in clinical decisions and treatment strategies. None declared. N/A.

Prevalence, associated factors and consequence of problematic smartphone use among adolescents and young adults in Bangladesh: A cross-sectional study.

Problematic smartphone use (PSU) and attention deficit hyperactivity disorder (ADHD) in children, adolescents, and young adults are of major concern to parents. However, the prevalence and associated factors related to these issues in Bangladeshi adolescents and young adults remain unclear to the best of our knowledge. The aim of this study is to assess PSU and ADHD in the context of adolescent and young adult age groups in Bangladesh. The present study collected data from diverse geographical locations in Bangladesh via face-to-face surveys using stratified random sampling methods. We considered age, sex, and geographic location stratification criteria. A total of 578 respondents participated in the survey initially. From this, we discarded 36 responses after screening because the information provided was insufficient or incomplete response. In the end, 542 replies were incorporated into the final analysis. PSU and ADHD depend on several factors, including the individual's demographic background. The prevalence of PSU and ADHD symptoms in adolescents and young adults in Bangladesh is 61.44% and 37.45%, respectively based on our findings. The symptoms of PSU are correlated with age, education level, family type (nuclear/joint), sleeping pattern, physical exercise, and residence area. ADHD symptoms are correlated with age, education level, living with family, smoking habit, physical disability, sleeping pattern, physical exercise, residence area, and PSU. Also, we observed that ADHD and PSU symptoms are positively correlated with each other. A large proportion of young adults and adolescents reported PSU and ADHD symptoms. The present findings have practical implications in clinical psychology, psychotherapy, and related policy considerations. We propose to develop an inclusive interventional strategy and community-based programs to address PSU and ADHD-related issues.

Evaluation of the Factors Influencing the Occurrence of Varicocele in Males Aged 15-35 in Mogadishu, Somalia

Testicular varicoceles, a common condition characterized by the dilation and enlargement of veins within the scrotum, are predominantly found in the adolescent and young adult age group. This condition can adversely affect testicular function in various ways, including decreased sperm production, reduced sperm quality, and even testicular atrophy. The prevalence of varicoceles varies across different regions, with estimates ranging from 15-20% in Somalia and other parts of Africa, 10-15% in Asia, and 15-20% in the United States and other parts of America. In the small island nation of Erub, the incidence is relatively lower, at around 5-10% of the male population. The exact etiology of varicoceles is not fully understood, but it is believed to be related to a combination of factors, such as genetic predisposition, anatomical abnormalities, and environmental influences. Certain risk factors, including obesity, sedentary lifestyle, and exposure to high temperatures, have been associated with an increased risk of developing varicoceles. While varicoceles can adversely affect testicular function and fertility, it is important to note that not all individuals with varicoceles experience fertility-related problems. The management of varicoceles often involves a multidisciplinary approach, with close monitoring and periodic evaluation being the recommended approach for asymptomatic individuals. In cases where varicoceles are causing symptoms or affecting fertility, various treatment options, such as surgical repair (varicocelectomy) or percutaneous embolization techniques, may be considered. Understanding the prevalence, etiology, and management strategies of varicoceles is crucial for healthcare professionals to provide appropriate care and support for individuals affected by this condition.

Kick Vaping: Feasibility, acceptability, and preliminary impact of a vaping cessation text messaging intervention for Latino young adults

Objective To assess the feasibility, acceptability, and preliminary impact of Kick Vaping among Latino young adults. Methods Forty Latino young adults (ages 18 to 25) who were currently vaping received Kick Vaping, a vaping cessation text messaging intervention available in English and Spanish. Feasibility was measured by the eligibility, enrollment, and follow-up rates. Acceptability was measured by overall satisfaction with the intervention. Preliminary impact was measured by self-reported 7-day point prevalence abstinence and changes in self-efficacy. Results Two hundred three individuals were identified, 61 were assessed for eligibility, and 55 were eligible. Forty individuals consented to participate and were enrolled in Kick Vaping. At baseline, most participants used disposable devices (70%), vaped daily (97.5%), had low (37.5%) or medium (35.0%) e-cigarette dependence, and had attempted to quit in the past year (72.5%). At Month 3, the follow-up rate was 90% (36/40). Treating those lost to follow-up as participants who continued vaping, 75% (30/40) of participants self-reported 7-day point prevalence abstinence. Self-efficacy mean scores significantly increased from 30.65 (SD 8.07) at baseline to 50.11 (SD 10.57) at follow-up (p < 0.01). Most participants (88.9%, 32/36) reported being satisfied/extremely satisfied with Kick Vaping. Conclusion It is feasible to recruit and retain Latino young adults in a vaping cessation text messaging intervention. Kick Vaping generated high satisfaction among Latino young adults, significantly increased self-efficacy, and resulted in a notable vaping cessation rate at Month 3. Additional testing in a randomized controlled trial is warranted to assess the efficacy of the intervention.

The Impact of Menstrual Disorders on Sleep Quality in Adolescents: An Observational Study

Premenstrual syndrome (PMS), dysmenorrhea, and abnormal uterine bleeding are frequent gynecological problems in adolescent girls. Studies show that sleep disorders and menstrual cycle irregularities are common conditions and indicate that they may occur together. Studies on the relationship between sleep quality and menstruation are mostly available for late adolescents (17 years and older) and young adult age groups. Our study aims to evaluate this relationship in adolescents aged 12-18. A survey study was structured and consisted of 4 sections. The first section includes anthropometric measurements and medical history of the participants; the second section includes "menstruation and menstruation symptoms history"; the third section includes "The Sleep Quality Scale and Sleep Variable Questionnaire"; and the fourth section includes the "Premenstrual Syndrome Assessment Scale" (PMSAS). Our survey was applied to those who visited the adolescent medicine outpatient clinic. The Sleep Quality Scale score was significantly lower in those with high PMSAS scores (P < .001). The participants who had dysmenorrhea and experienced other symptoms during menstruation had significantly lower SQS scores and sleep efficiency (SE) (P < .001). There was no significant difference between heavy menstrual bleeding, defined as lasting more than 7 days, requiring more than 5-6 pads/tampons per day, and SE/quality (P > .05). According to our study, dysmenorrhea and the presence of PMS may negatively affect the sleep quality of adolescents. Health professionals dealing with young people should take into account the effects of menstrual problems on sleep quality and offer appropriate support/treatment options.

The acute effect of time-restricted feeding (12 & 16 h) and varying exercise intensities on fat-oxidation rate in inactive young adults – a randomized control trial

Background and purposeTime-restricted feeding (TRF) is a dietary pattern that alternates between periods of fasting and feeding, which has gained significant attention in recent years. The 16/8 approach consists of fasting for 16 h and feeding for an 8-h window, while the 12/12 method consists of fasting for 12 h and a 12-h feeding window. Limited research exists comparing the effects of these methods coupled with physical activity (PA). The aim of this investigation was to examine the acute effects between conditions of varying TRF durations (12 and 16 h) and PA intensities on the fat oxidation rate (FOR). It was hypothesized that i) the TRF16 conditions would exhibit higher FORmax and that PA would enhance these effects, and ii) High Intensity Interval Training (HIIT) would result in greater effects on FORmax compared to Low-Moderate Intensity Steady State Continuous Training (MICT) PA.Methods and resultsEighteen young adults (age: 23 ± 2.0 yrs., body mass index: 23.5 ± 2.8 kg·m−2) were recruited and participated in the supervised intervention. The discrete component open circuit spirometry system was used to measure oxygen consumption (VO2), and Frayne’s equation was used to determine the FOR plus FORmax. ANOVA was used to determine pre/post-intervention differences in FORmax. The FORmax for the TRF16 + HIIT intervention was significantly higher than the TRF12 (mean difference = 0.099 g·min-1, p = 0.011, 95% CI 0.017 to 0.180) and TRF16 fast alone (mean difference = 0.093 g·min-1, p = 0.002, 95% CI 0.027 to 0.159). The FORmax for TRF12 + HIIT intervention was significantly higher than the TRF12 fast alone (mean difference = 0.070 g·min−1, p = 0.023, 95% CI 0.007 to 0.134). The TRF16 + HIIT intervention was also significantly higher than the TRF12 fast alone (mean difference = 0.099 g·min−1, p = 0.011, 95% CI 0.017 to 0.180).ConclusionThis study contributes to the ever-growing body of literature on the acute effects of TRF and PA on young adult males and females. The findings suggest that the TRF16 + HIIT PA intervention results in the highest FORmax. Trial registrationRetrospective Registration ISRCTN # 10076373 (October 6, 2023).

Strategies for Coping with Minority Stress among Queer Young Adults: Usage Frequency, Associations with Demographics, and Mental Health.

Queer young adults report significantly higher levels of anxiety and depression than their heterosexual counterparts, which is linked to sexual minority stress. Therefore, it is important to understand the coping strategies employed by this population to navigate minority stress and how coping strategies may impact mental health outcomes. Drawing from a U.S. national diverse sample of 387 queer young adults (ages 18-39 years), we analyzed descriptive results of 11 behavioral strategies to cope with minority stress and used ordered logistic and linear regression to examine the following objectives: the frequency of the use of each coping strategy, and the associations between each strategy and demographic characteristics as well as depression and anxiety. Results revealed that avoidance and talking with friends were the most frequently utilized coping strategies, while prayer/religious activities and counseling/psychotherapy/support groups were infrequently used. We examined utilization preferences of coping strategies across demographic factors (e.g., assigned sex at birth and sexual orientation). The use of counseling/psychotherapy/support group was positively associated with mental health symptoms, while exercise and mindfulness/mediation were associated with lower mental health symptoms. Our findings provide insights for mental health researchers and professionals in selecting appropriate coping strategies for queer young adults in prevention and intervention efforts.

Disparities in self-reported pain control among cancer survivors.

151 Background: Cancer survivors often suffer from chronic pain. However, not all patients have access to medication and other pain management strategies, making pain control challenging. We aim to determine the association of sociodemographic factors with self-reported pain control in cancer survivors with cancer-related chronic pain. Methods: A cross-sectional analysis was conducted using data from the 2022 Behavioral Risk Factor Surveillance System survey. Cancer survivors who self-reported physical pain from cancer or treatment were included. Non-melanoma skin cancer survivors were excluded. The outcome of interest was pain control. Univariate analysis with chi-square and multivariable logistic regression were used to determine the sociodemographic characteristics associated with pain control. Models were adjusted for age, sex, marital status, income, insurance coverage, BMI, smoking status, and cancer site. Results: 1,670 cancer survivors with self-reported cancer-related chronic pain were identified. 9.2% were aged &lt; 40, 61.5% were female, and 71.6% were non-Hispanic white. 97.2% were insured, 50.5% earned ≥ $50,000, and 27.6% were college graduates. 29.8% of survivors reported a history of breast cancer, followed by melanoma (6.3%), and lung cancer (6.1%). Young adults (age 18-39) reported significantly lower pain control compared to older survivors (52% vs. 77.7%, p &lt;0.001). Non-Hispanic Black survivors reported the highest rates of pain control, followed by non-Hispanic white, and Hispanic survivors (87.7% vs. 77.5% vs. 60.6%, respectively, p= 0.013). Employed survivors reported significantly higher pain control than those out of the workforce (83.2% vs. 73.7%, p= 0.008, respectively). College graduates reported better pain control than those without a college degree (82.9% vs. 74.7%, p=0.009, respectively). There was no significant association between pain control and insurance coverage or income. On multivariate analysis, young adults had lower pain control than older adults (OR: 0.454; 95% CI: 0.219-0.942). Compared to non-Hispanic white survivors, being Hispanic was associated with worse pain control (OR: 0.324; 95% CI: 0.142-0.737); no significant association was found for non-Hispanic Black survivors (OR: 1.964; 95% CI: 0.851-4.631). Employment was associated with better pain control (OR: 1.997; 95% CI: 1.235-3.231). College degree attainment was not significantly associated with pain control on multivariate analysis (OR: 1.414; 95% CI: 0.934-2.142). Conclusions: Age, race/ethnicity and employment were associated with pain control among cancer survivors. Young adults, Hispanic and unemployed survivors were most likely to have poor pain control. Further research should elucidate the factors driving these relationships in order to achieve more equitable pain management in this population.

Hypoparathyroidism: A dark horse differential in young age cataracts

In India, cataracts account for the lion’s share of cases of blindness. Age is still the single most important risk factor for cataracts. Cataracts in the young adult age group are less common and are usually secondary to various local and systemic conditions. The aetiology may be a challenging one to ascertain in certain cases of young-age cataracts. A rapidly developing cataract in a young age individual may further add to the diagnostic dilemma especially when the patient presents with multi-system affection necessitating the widening of the horizons of suspected local and systemic pathologies at play. Therefore, we report a case of a 25-year-old lady who presented with a history of seizures, headache, disc oedema and progressive bilateral blurring of vision due to rapidly developing cataracts over 4 months in a case of primary hypoparathyroidism. Correction of the underlying abnormalities resulted in the resolution of disc oedema and headache. Furthermore, the patient had no episodes of seizures in the 1½ years of follow-up. In addition, full visual recovery was achieved after bilateral cataract surgery. Awareness of this rare presentation can help in the early diagnosis and evaluation of cataracts, besides correction of the systemic pathologies for an overall better patient outcome.

Effects of Very Low Nicotine Content Cigarettes and Nicotine Vaping Device Characteristics on Choices to Smoke, Vape, or Abstain in Early Young Adults.

A national nicotine reduction policy could reduce the public health toll of smoking. However, reducing nicotine in cigarettes may lead to changes in the use of other tobacco products such as nicotine vaping devices, particularly among young people. Product use outcomes may depend on characteristics of available nicotine vaping devices. We aimed to determine the impact of cigarette nicotine content, vaping device nicotine concentration, and vaping device flavors on choices to smoke, vape, or abstain. Early young adults (ages 18-20 inclusive, N=80) who reported smoking daily and vaping nicotine at least twice in their lifetime participated in a laboratory study. Participants received either Very Low Nicotine Content (VLNC; 0.4mg nicotine/g of tobacco) or Normal Nicotine Content (NNC; 15.8mg/g) cigarettes. First, participants chose between their assigned cigarette or abstaining. Subsequently, participants chose between 2 cigarette puffs, 2 vape puffs, or abstaining. Vaping device nicotine concentration (3mg vs. 18mg/ml) and flavor (tobacco vs. non-tobacco) were manipulated within-subjects. When only cigarettes were available, there were no differences between the VLNC and NNC groups on cigarette choices. When the nicotine vaping device was concurrently available, the VLNC group made fewer choices to smoke than the NNC group. Non-tobacco flavors and lower vaping device nicotine concentration were associated with fewer choices to smoke. Nicotine vaping device availability reduced choices to smoke VLNC cigarettes, and vaping devices with lower nicotine and non-tobacco flavors led to the fewest choices to smoke. Regulators should consider that the availability and characteristics of alternative tobacco products can moderate the product standard's impact. The U.S. Food and Drug Administration may enact a reduced nicotine product standard that would affect all commercially-available cigarettes. One important population affected by this policy would be early young adults who smoke. We aimed to determine the impact of cigarette nicotine content, vaping device nicotine concentration, and vaping device flavors on choices to smoke, vape, or abstain. Lower nicotine in cigarettes, along with non-tobacco flavors and lower nicotine concentration in the vaping device, were associated with the fewest choices to smoke. Regulators should consider that the availability and characteristics of alternative tobacco products can moderate the product standard's impact.

Cochlear-implant simulated spectral degradation attenuates emotional responses to environmental sounds

Objective Cochlear implants (CI) provide users with a spectrally degraded acoustic signal that could impact their auditory emotional experiences. This study evaluated the effects of CI-simulated spectral degradation on emotional valence and arousal elicited by environmental sounds. Design Thirty emotionally evocative sounds were filtered through a noise-band vocoder. Participants rated the perceived valence and arousal elicited by each of the full-spectrum and vocoded stimuli. These ratings were compared across acoustic conditions (full-spectrum, vocoded) and as a function of stimulus type (unpleasant, neutral, pleasant). Study Sample Twenty-five young adults (age 19 to 34 years) with normal hearing. Results Emotional responses were less extreme for spectrally degraded (i.e., vocoded) sounds than for full-spectrum sounds. Specifically, spectrally degraded stimuli were perceived as more negative and less arousing than full-spectrum stimuli. Conclusion By meticulously replicating CI spectral degradation while controlling for variables that are confounded within CI users, these findings indicate that CI spectral degradation can compress the range of sound-induced emotion independent of hearing loss and other idiosyncratic device- or person-level variables. Future work will characterize emotional reactions to sound in CI users via objective, psychoacoustic, and subjective measures.

Parental financial support and family emotional support to young adults during COVID-19: A help or a hindrance?

The present study focuses on the role of family support to young adult children during COVID-19 in ameliorating the negative financial impact of the pandemic. Guided by the Conservation of Resources (COR) Theory of stress and coping, we conceptualize the negative financial impact due to COVID-19 as a source of financial stress that would be associated with lower levels of both financial wellbeing and positive outlook of young adults. We rely on data collected from a multinational sample of young adults (ages 18-30) from six countries (China, Italy, Lithuania, Portugal, Slovenia, US; N = 2102) over a 3-month period (July 2020-September 2020). We tested the potential effects of two types of support (i.e., parental financial support and family emotional support) using path analysis. While we find a consistent positive association between family emotional support and both financial wellbeing and positive outlook, we also find a consistent negative association between parental financial support and financial wellbeing, and a nonsignificant or negative association (Lithuania only) with a positive outlook. The significant interaction between COVID-19 financial impact and family emotional support on young adults' positive outlook reveals that the benefit of family emotional support is more evident when the negative financial impact is low or moderate. We discuss the implications of these findings in assisting young adults to cope with financial disruptions.

Professional youth workers’ views on involuntary loneliness and its alleviation among adolescents and young adults

ABSTRACT There is scant research on professional youth workers’ perspectives on adolescents and young adults’ involuntary loneliness, although they can support young people’s well-being. The aim was to explore professional youth workers’ views on involuntary loneliness and its alleviation among adolescents and young adults (ages 18–29). A qualitative exploratory design, three focus group interviews and one individual interview, a total of fifteen professional youth workers. Three main categories (Characteristic features of involuntary loneliness among adolescents and young adults, Risk factors for involuntary loneliness among adolescents and young adults, Strategies for alleviating or reducing involuntary loneliness among adolescents and young adults) and fourteen subcategories emerged. Involuntary loneliness has changed and often exists alongside other mental health issues. Several risk factors exist but even different strategies whereby it can be reduced or alleviated. Exploration of which strategies effectively target involuntary loneliness among adolescents and young adults should be undertaken in future research.

Trends in cannabis and tobacco co-use in the United States, 2002–2021

BackgroundCo-use of cannabis and tobacco poses greater risks than use of either substance individually and may be becoming more prevalent with increasing cannabis medicalization and legalization. We aimed to assess trends in the prevalence of cannabis and tobacco co-use between 2002–2019 and identify the updated prevalence and correlates of co-use in 2021 among US adults. MethodsThis study used data from the 2002–2021 National Survey on Drug Use and Health, a nationally-representative, cross-sectional survey in the US. We assessed prevalence trends in past 30-day cannabis and tobacco co-use, exclusive cannabis use, and exclusive tobacco use overall and by sociodemographic group using joinpoint regression. Additionally, multinomial models identified correlates of co-use in 2021. ResultsIn 2021, the weighted prevalence of cannabis and tobacco co-use was 6.38 %, the weighted prevalence of exclusive cannabis use was 7.28 %, and the weighted prevalence of exclusive tobacco use was 15.01 %. From 2002 to 2019, the prevalence of past 30-day co-use of cannabis and tobacco increased significantly (annual percentage change [APC]: 1.9 [1.4–2.4], P<0.05) among the overall US population. All subgroups of sex, race/ethnicity, and age also saw significant increases in co-use, other than young adults ages 18–25, for whom co-use was stagnant between 2002–2014 and then decreased significantly between 2014–2019. ConclusionThis study identified increasing cannabis and tobacco co-use overall and among most sociodemographic strata in the US. As cannabis policy changes rapidly, co-use requires closer surveillance, clinical screening, and dedicated research.

Association Between Cardiovascular Health and Subclinical Atherosclerosis Among Young Adults Using the American Heart Association's "Life's Essential 8" Metrics.

This study investigated the association of American Heart Association's cardiovascular health guidelines Life's Essential 8 (LE8) and Life's Simple 7 (LS7) with carotid artery outcomes among young adults. This cross-sectional study included 240 young adults (age 24.2±1.6 years) who underwent a carotid ultrasound between 2018 and 2022. LE8 score was calculated from 4 health factors (body mass index, non-high-density lipoprotein cholesterol, fasting glucose, and blood pressure), and 4 health behaviors (dietary intake, physical activity, tobacco use, and sleep). LS7 was calculated from 7 metrics (all LE8 metrics, except for sleep) with a simpler algorithm. Higher LE8 and LS7 scores both indicate better health and better adherence to American Heart Association guidelines. Carotid artery outcomes included carotid artery intima-media thickness, arterial stiffness (eg, distensibility), and echogenicity determined by grayscale median of the intima media complex. Results of linear regression analyses, adjusting for age, sex, ethnicity, and parents' highest degree, indicated that a 1-SD increase in LE8 score was associated with 12.14 μm lower carotid artery intima-media thickness (95% CI, -20.93 to 3.35), 1.17 (10-6×m2/N) greater distensibility (95% CI, 0.09-2.24), suggesting less arterial stiffness, and 2.66 μm greater grayscale median of the intima media complex (95% CI, 0.58-4.75), suggesting less lipid deposition. Analyses using LS7 score demonstrated comparable findings. Health factor metrics demonstrated stronger association with carotid artery outcomes, as compared with behavior metrics. Greater adherence to the American Heart Association's cardiovascular health guidelines is associated with lower risk for subclinical atherosclerosis in young adults. LE8 and LS7 demonstrated comparable associations with carotid artery outcomes.

Youth and young adult knowledge of and access to opioid harm reduction policies and interventions in North Carolina

IntroductionFrom 2019–2021, overdose deaths among youth and young adults ages 10–19 years of age residing in the United States increased by 109 %. We sought to examine the extent to which youth and young adults who have experience with substance use are aware of the harm reduction policies and interventions, including the statewide Good Samaritan Law (GSL), naloxone, and fentanyl test strips, and have access to naloxone and fentanyl test strips. MethodsFrom December 2022 to February 2023, we conducted a cross-sectional telephone survey of individuals ages 12–25 years who resided in North Carolina (NC) (N=15,000). We assessed awareness of and access to harm reduction policies and interventions among participants who reported ever using heroin/fentanyl, diverted prescription medication, cocaine, methamphetamine, and hallucinogens (n=539). Logistic regression models were used to identify factors associated with awareness of and access to these policies and interventions. ResultsWe found that 81.5 % of the sample of youth and young adults who reported ever use of substances were aware of NC’s GSL, 80.0 % were aware of naloxone, 43.0 % perceived they had access to naloxone, 74.4 % were aware of fentanyl test strips, and 21.9 % perceived they had access to fentanyl test strips. There were individual and community-level characteristics associated with awareness of and perceived access to these harm reduction policies and interventions. ConclusionsEfforts are needed to improve access to harm reduction interventions among youth and young adults as they are experiencing an increased risk of dying from opioid-involved overdoses.
