Project description:PurposeTo (1) describe rates of suicidal behaviors in a sample of college students, (2) evaluate sex differences, and (3) provide a preliminary examination of the unique association of sluggish cognitive tempo (SCT) symptoms and other mental health dimensions in relation to suicidal behaviors in college students.MethodsParticipants were 1,704 college students from two universities who completed measures assessing mental health symptoms and suicidal behaviors (i.e., past ideation/attempts, past-year ideation, disclosure of intent to commit suicide to another person, and likelihood of a future suicide attempt).ResultsFour percent of participants reported a previous suicide attempt and 2.2% indicated that it was likely they would attempt suicide someday. 7.5% reported thinking about killing themselves often in the past year; 41.4% of these participants reported they had never told someone they might attempt suicide. Approximately one quarter (24%) of participants were classified with suicide risk based on an empirically established cutoff score, though rates differed between women (26.1%) and men (20.4%). Women were also more likely than men to report a previous suicide attempt and to tell someone else about their suicidal ideation. In regression models, depression was the strongest correlate of suicidal behaviors. Attention-deficit/hyperactivity disorder symptoms were unassociated with suicidal behaviors when accounting for internalizing symptoms. SCT remained significantly associated with increased suicidal behaviors beyond other mental health dimensions including depression.ConclusionsA substantial minority of college students report suicidal behaviors, with sex differences dependent on the specific behavior examined. This study provides the first evidence linking SCT to suicidal behaviors in young adults.

Project description:Alcohol displays on Facebook are ever-present and can be socially desirable for college students. As problematic drinking is a concern for college students, this research sought to understand how different types of information on a Facebook page influence likelihood to drink. Telephone interviews were conducted with 338 incoming college freshmen from two large national universities. Data were obtained from a vignette prompt which presented a scenario in which a senior college student's Facebook profile displayed wall-posts, pictures, and status updates that were drinking-related or pro-social in nature. Participants were asked to report intention to drink alcohol with that student if together at a party. Findings supported the hypotheses: wall-posts were most influential (the stickiest), followed by pictures, followed by status updates. Findings provide additional empirical support for established online impression formation patterns, and additionally provide evidence that virtual cues are being ingrained as schema in interpersonal communication. These results are discussed in relation to the conception of "sticky cues" in impression formation.

Project description:BackgroundLifestyle behaviors are developed during young adulthood and carried through life. Accordingly, early detection of unhealthy behaviors can help prevent the increase in non-communicable diseases in the population. College students are an especially vulnerable group who, upon entering a new environment, tend to engage in unhealthy behaviors.ObjectiveThe present study aims to evaluate the lifestyle behaviors of Kuwaiti college students and their association with markers of academic achievements.MethodsOne thousand two hundred fifty-nine students participated in the present study and answered an online questionnaire pertaining to their sociodemographic status, academic performance indicators, body weight and height, and lifestyle behaviors. Data were collected from November 2020 to February 2021.ResultsResults of the present study showed that obesity was significantly more prevalent among male participants than among females even though males were more physically active. Alternatively, females had a greater grade point average in college, slept more, and had more screen time. Interestingly, we were unable to detect a significant correlation between lifestyle behaviors and academic achievements.ConclusionThe observed differences in body mass index between genders may have been attributed to energy intake rather than energy expenditure.

Project description:BackgroundWhile suicidal thoughts and behaviors (STB) among college students are common, the associations between STB and academic performance are not well understood.MethodsAs part of the World Mental Health Surveys International College Student project, web-based self-reported STB of KU Leuven (Leuven, Belgium) incoming freshmen (N=4921; response rate=65.4%) was collected, as well as academic year percentage (AYP), and the departments to which students belong. Single- and multilevel multivariate analyses were conducted, adjusted for gender, age, parental educational level, and comorbid lifetime emotional problems.ResultsLifetime suicide plan and attempt upon college entrance were associated with significant decreases in AYP (3.6% and 7.9%, respectively). A significant interaction was found with average departmental AYP, with STB more strongly associated with reduced AYP in departments with lower than higher average AYP.LimitationsLimited sample size precluded further investigation of interactions between department-level and student-level variables. No information was available on freshman secondary school academic performance.ConclusionsLifetime STB has a strong negative association with academic performance in college. Our study suggests a potential role for the college environment as target for treatment and prevention interventions.

Project description:ObjectiveThe objectives were to examine (1) sex differences in factors associated with indoor tanning, and (2) the relationship between cancer risk perception and skin cancer screening among indoor tanners.MethodsData are from the 2010 National Health Interview Survey. The sample was limited to U.S. adults (? 18 years) using an indoor tanning device in the last year (N = 1177). We conducted bivariate and multivariate weighted analyses.ResultsAmong indoor tanners, less than 30% of men and women reported having ever had a skin exam. Male sex was significantly associated with rarely/never using sunscreen (51.4% of men vs. 36.4% of women) and with binge drinking of alcohol (47.6% of men vs. 37.4% of women). No sex differences in smoking were present. Indoor tanners who perceived themselves "about equally likely" to develop cancer (any type) as similar others were less likely to have received a skin cancer examination than those with high perceived risk.ConclusionThe relationship of cancer risk perception to skin cancer screening is complex. Rates of risk and protective behaviors observed among men and women who indoor tan suggest mixed-sex tanning prevention efforts should target multiple risk behaviors.

Project description:Background/aimsThe role of psychosocial factors on irritable bowel syndrome (IBS) in adolescents is incompletely understood. The aim of this study is to investigate the association between the psychosocial factors and the risk of developing IBS in college freshmen.MethodsA cross-sectional survey was conducted in a randomly selected freshmen population in Wuhan China (n = 2449). Questionnaire evaluated demographics and psychosocial risks. The population was divided into 3 groups: non-discomfort, chronic abdominal discomfort and IBS. The association between the development of IBS and psychosocial factors was analyzed by ordinal and multiple logistic regression analysis.ResultsA total of 2053 (83.8%) completed this survey (mean age, 18.2 ± 0.9 years; female, 35.6%). Among them, 82 (4.0%) fulfilled the Rome III criteria for IBS. Female (odds ratio [OR], 3.31; 95% confidence interval [CI], 2.47-4.45), experience of abuse (OR, 2.44; 95% CI, 1.10-5.56), and suicidal intention (OR, 2.17; 95% CI, 1.15-4.17) were more likely to have IBS. Compared with chronic abdominal discomfort, however, depression (OR, 5.55; 95% CI, 1.36-22.71) was the only dependent risk factor for IBS.ConclusionThe prevalence of IBS in college freshmen is 4.0%, and to the freshmen, psychosocial factors such as experience of abuse, depression, and suicidal intention were associated with high risk of developing IBS.

Project description:ObjectiveAmong northeast Asians, the variant aldehyde dehydrogenase allele, ALDH2*2 (rs671, A/G, minor/major), has been inversely associated with alcohol dependence. The strength of the associations between ALDH2*2 and drinking behaviors depends on the developmental stage, the phenotype studied, and other moderating variables. This study examined ALDH2 gene status as a moderator of the associations between parental drinking, peer drinking, and acculturation with alcohol use among 222 Chinese American and Korean American college freshmen.MethodNegative binomial regressions were used to test the main and interactive effects of ALDH2 with contextual factors on alcohol frequency (drinking days) and quantity (drinks per drinking day) in the past 3 months.ResultsALDH2*2 was associated with more subjective flushing symptoms and longer length of flushing but was unrelated to both alcohol frequency and quantity. Peer drinking was positively associated with both alcohol frequency and quantity, but neither was moderated by ALDH2. We observed a nonsignificant trend for the interaction between parental drinking and ALDH2 on alcohol frequency, where parental drinking was positively associated with alcohol frequency only among participants with ALDH2*2. We found a significant interaction between acculturation and ALDH2 on alcohol frequency, where acculturation was positively associated with alcohol frequency only among those with ALDH2*2. Exploratory analyses stratified by Asian ethnic subgroup indicated that this interaction was driven primarily by the Korean subsample.ConclusionsParental drinking and acculturation may facilitate more frequent drinking among those who have more intense reactions to alcohol (i.e., those with ALDH2*2) during the transition from high school to college.

Project description:The prevalence of obesity and eating disorders varies by sex, but the extent to which sex influences eating behaviors, especially in childhood, has received less attention. The purpose of this paper is to critically discuss the literature on sex differences in eating behavior in children and present new findings supporting the role of sex in child appetitive traits and neural responses to food cues. In children, the literature shows sex differences in food acceptance, food intake, appetitive traits, eating-related compensation, and eating speed. New analyses demonstrate that sex interacts with child weight status to differentially influence appetitive traits. Further, results from neuroimaging suggest that obesity in female children is positively related to neural reactivity to higher-energy-dense food cues in regions involved with contextual processing and object recognition, while the opposite was found in males. In addition to differences in how the brain processes information about food, other factors that may contribute to sex differences include parental feeding practices, societal emphasis on dieting, and peer influences. Future studies are needed to confirm these findings, as they may have implications for the development of effective intervention programs to improve dietary behaviors and prevent obesity.

Project description:This study aims to investigate sex differences in ratings for facial attractiveness (FA) and vocal attractiveness (VA). Participants (60 undergraduates in Study 1 and 111 undergraduates in Study 2) rated the attractiveness of computerized face images and voice recordings of men and women. In Study 1, face images and voice recordings were presented separately. Results indicated that men generally rated voice recordings of women more attractive than those of men, whereas women did not show different attractiveness ratings for voices of men vs. women. In Study 2, face images and voice recordings were paired as multimodal stimuli and presented simultaneously. Results indicated that men rated multimodal stimuli of women as more attractive than those of men, whereas women did not differentiate multimodal stimuli of men vs. women. We found that, compared to VA, FA had a stronger influence on participants' overall evaluations. Finally, we tested the difference between "original multimodal stimuli" (OMS) and "non-original multimodal stimuli" (non-OMS) and found the "OMS-facilitating effect." Taken together, findings indicated some sex differences in FA and VA in the current study, which could be used to interpret behaviors of sexual selection, human mate preferences, and designs and popularization of sex robots.

Project description:Adult reproductive behaviors in Drosophila melanogaster males and females are vastly different. Yet, neurons that express sex-specifically spliced fruitless transcripts (fru P1) underlie these behaviors in both sexes. How the same set of neurons can drive such different behaviors is an important and unresolved question in developmental genetics. A particular challenge is that fru P1-expressing neurons are only 2-5% of the adult nervous system, making studies of adult head tissue, or even the whole brain, unlikely to yield informative inferences. Translating Ribosome Affinity Purification (TRAP) identifies the actively translated pool of mRNAs from fru P1-expressing neurons and allowed us to conduct a sensitive, cell-specific assay of gene expression. The male and female fru P1-expressing neurons have a shared set of 1,642 genes with enriched TRAP transcripts that form a distinct repertoire, relative to TRAP analyses of all neurons in the adult head. Further, there are a striking number of genes (3,147) that have sex-biased TRAP enrichment in fru P1-expressing neurons. Yet, most of these genes (3,107) have only male-biased TRAP enrichment. This suggests an underlying mechanism to generate dimorphism in behavior, with the transcript repertoire that specifies female behaviors present in both sexes and a large additional set of genes with expression in the male dramatically altering the pattern. Thus, these additional genes invoke the male-specific behaviors by establishing cell fate in the same context of gene expression observed in females. These results suggest a possible global mechanism for how distinct behaviors can arise in different environments, from a shared set of neurons. Libraries were prepared from five independent biological replicates, from TRAP adult heads samples from males and females, and the mRNA input from adult heads from males and females. For each experimental condition, approximately 1,000 flies that were 8 to 24 hours post-eclosion were used.
