Personality traits and BMI trends over three years in Japanese University students

ABSTRACT: In Europe and America, associations between personality traits and body-mass index (BMI) have been reported. However, in Japan, the association between personality traits and BMI (i.e., thinness and obesity) has not been well studied. In this study, we investigated the relationship between Temperament and Character Inventory (TCI) personality traits and changes in BMI status among Japanese students during their university attendance. We measured the height and weight of 5,340 students in a Japanese university during annual medical checkups and calculated their BMI. We measured the students’ personality traits using the short Japanese version of the TCI at university admission. The participants were divided into seven groups based on how BMI changed from the first year to the fourth year at university. In men, compared to the group that maintained normal BMI status (N = 2,189) over time (i.e., the control group), the group that maintained thinness status (N = 226) were lower in Reward Dependence, and the group whose status improved from thinness to normal (N = 117) were higher in Harm Avoidance. In women, compared with the control group (N = 1,510), the group that maintained thinness status (N = 302) were lower in Novelty Seeking, and the group whose status worsened from normal to thinness (N = 127) were higher in Harm Avoidance. Associations were found between thinness and TCI personality traits among Japanese university students. A practical implication of these results is that it is necessary to consider individuals’ personality traits to plan and implement effective preventive interventions for thinness.

Project description:BackgroundProcrastination is a psychological trait that causes individuals to put off doing things that need to be done. It has recently shown to result in the worsening of symptoms due to delays in seeking medical care. However, it is not clear how perception of dental disease influences dental visits. This study examined the associations of procrastination and personality traits with delayed dental visits for both acute and chronic conditions.MethodsOf 599 university students queried, the data of 549 subjects (mean age 19.7 years) were analyzed. A general procrastination scale (GPS), the Big Five personality traits, and oral hygiene habits were used for analysis. The participants were asked about illness awareness conditions related to dental disease, perception of pain in the oral region due to acute oral symptoms and chronic symptoms. The participants were asked the number of days until they decided that treatment was required. Based on the bimodal shape of the distribution, those who answered at least eight days for acute or chronic conditions were classified as the procrastination (P) group and the others as the non-procrastination (Non-P) group.ResultsSignificant differences in GPS scores were found between the groups for both acute and chronic conditions, with significant differences in the Big Five traits of extraversion, agreeableness, and neuroticism for an acute condition and extraversion, openness, and neuroticism for a chronic condition. There were no significant differences regarding oral hygiene habits between the groups for either condition. Next, using a Bayesian network, the probabilistic causal relations among procrastination, the Big Five traits, and delays in dental visits for both acute and chronic conditions were analyzed. Among the Big Five traits, conscientiousness and neuroticism were directly related to GPS score. Interestingly, agreeableness was directly related to delays in dental visits only for an acute condition and showed a negative effect, while dental student status had a positive effect on delays in dental visits.ConclusionsThe results showed that procrastination and dentistry department are factors that directly influence delays in dental visits, while agreeableness, a Big Five trait, has a negative effect on individuals with an acute condition.

Project description:IntroductionRecent estimates suggest that there is a substantial number of Japanese students with developmental disabilities. This study aimed to examine potential associations between autistic, autistic subcomponents, and attention deficit/hyperactivity disorder (ADHD) traits with student performance (as measured by presenteeism) and class attendance among Japanese university students.MethodsParticipants comprised 721 students from different regions of Japan who completed a self-administered internet survey. Autistic and ADHD traits were measured using an abridged version of the autism spectrum quotient (AQ-Short) and adult ADHD self-report scale (ASRS). Presenteeism, which is an indicator of student performance, was assessed using the modified World Health Organization Health and Work Performance Questionnaire. Class attendance during the past year was self-reported by participants.ResultsStudents with high levels of autistic traits and high levels of ADHD traits were significantly more likely to report poor student performance (odds ratio [OR] = 3.07, 95% confidence interval [95% CI]: 1.90-4.96; and OR = 2.13, 95% CI: 1.32-3.42, respectively). Regarding autistic trait subcomponents, students with high levels of preference for routine (OR = 2.39, 95% CI: 1.38-4.13) and high levels of difficulties with social skills (OR = 1.81, 95% CI: 1.03-3.18) were also significantly more likely to report poor student performance. There were borderline significant associations between traits of attention-switching difficulties and poor student performance (OR = 1.78, 95% CI: 1.00-3.15). Regarding ADHD trait subcomponents, students with high levels of inattention (OR = 2.88, 95% CI: 1.32-6.26) were also significantly more likely to report poor student performance. Students with both high levels of autistic traits and high levels of ADHD traits were more likely to report poor student performance than those with high levels of only one trait type. There were, however, no statistically significant associations between these traits and low class attendance risk.ConclusionsSickness presenteeism was significantly associated with high levels of both autistic traits and ADHD traits among Japanese university students.

Project description:BackgroundTrends in New Zealand (NZ) medical students' health and the influence of a wellbeing curricula are unknown.MethodsThe author's collected self-report data from NZ medical students on 'Graduation Day' from 2014 to 2018, using a serial cross-sectional survey design with validated scales assessing psychological health, stigma, coping, and lifestyle. Comparisons were made with NZ general population same-age peers. Analyses examined trends, differences between 'cohorts' of students receiving different exposures to a wellbeing curriculum, and correlations between students' own lifestyle practices and their frequency of talking with patients about those topics.ResultsOf 1,062 students, 886 participated. The authors found statistically significant self-reported increases from 2014 to 2018 for negative psychological indices, including scores for distress and burnout, suicidal thoughts in the preceding year, and the likelihood of being diagnosed with an anxiety disorder. There was a significant increase in numbers of students reporting having their own doctor as well as increased healthy coping strategies and a significant decrease in stigma scores. Academic cohorts of students who had completed a wellbeing curriculum were more likely to report high distress levels, having been diagnosed with a mood disorder, and being non-drinkers than students without wellbeing training. When compared to NZ peers, medical students smoked less, exercised more, and were less likely to have diagnosed mood and anxiety disorders, but reported more distress. The authors found a significant correlation between the amount of exercise students undertook and their likelihood to discuss exercise with patients.ConclusionsNZ medical students have better physical health than general population peers and are more likely to discuss exercise with patients if exercising themselves. However, cohorts of graduating students report increasing distress despite the implementation of a wellbeing curriculum. Research is needed into mechanisms between students' self-awareness, willingness to report distress, stigma, mind-set, coping, and psychological outcomes, to inform curriculum developers.
