Cognitive Skills and DNA Methylation Are Correlating in Healthy and Novice College Students Practicing Preksha Dhyana Meditation.

ABSTRACT: The impact of different meditation protocols on human health is explored at the cognitive and cellular levels. Preksha Dhyana meditation has been observed to seemingly affect the cognitive performance, transcriptome, and methylome of healthy and novice participant practitioners. In this study, we performed correlation analyses to investigate the presence of any relationships in the changes in cognitive performance and DNA methylation in a group of college students practicing Preksha Dhyāna (N = 34). Nine factors of cognitive performance were assessed at baseline and 8 weeks postintervention timepoints in the participants. Statistically significant improvements were observed in six of the nine assessments, which were predominantly relating to memory and affect. Using Illumina 850 K microarray technology, 470 differentially methylated sites (DMS) were identified between the two timepoints (baseline and 8 weeks), using a threshold of p-value < 0.05 and methylation levels beyond -3% to 3% at every site. Correlation analysis between the changes in performance on each of the nine assessments and every DMS unveiled statistically significant positive and negative relationships at several of these sites. The identified DMS were in proximity of essential genes involved in signaling and other important metabolic processes. Interestingly, we identified a set of sites that can be considered as biomarkers for Preksha meditation improvements at the genome level.

Project description:BackgroundSeeking online health information (OHI) has become a common practice globally. The information seekers could face health risks if they are not proficient in OHI literacy. The OHI-seeking behaviors and skills of Chinese college students, the largest proportion of college students in the world, are understudied. This study was aimed to describe OHI-seeking behaviors and skills of college students in Guangdong, China.MethodsCollege students in the Guangdong province with OHI-seeking experience were invited via WeChat, QQ, and Sina Weibo using QR code posters and flyers for participation in this online anonymized questionnaire-based study. Data on demographics, OHI literacy, information resources, search approaches, and behaviors were collected. The relationship between perceived OHI literacy and high-risk behaviors was investigated by bivariate logistic regression analysis.ResultsRespondents were 1203 college students with a mean age of 20.6 years, females (60.2%), and undergraduates (97.2%). They sought health information via websites (20.3%), WeChat (2.6%), or both (77.1%). Baidu was the main search engine, and baike.baidu.com (80.3%), Zhihu.com (48.4%), and Zhidao.baidu.com (35.8%) were top three among 20 searched websites for information about self-care (80.7%), general health (79.5%), disease prevention (77.7%), self-medication (61.2%), family treatment (40.9%), drugs (37.7%), western medications (26.6%), hospitals (22.7%), physicians (21.4%), and Traditional Chinese Medicine (15.6%). Despite most respondents (78%) lacked confidence in the evidence quality and satisfaction with the results, only 32.4% further consulted doctors. Many (> 50%) would recommend the retrieved information to others. About 20% experienced hacking/Internet fraud. Cronbach's alpha for the internal consistency of OHI literacy was 0.786. Bivariate logistic regression analysis showed that students who believed they can judge the evidence level of OHI were more likely to self-diagnose (OR = 2.2, 95%CI, 1.6-3.1) and look for drug usage (OR = 3.1, 95%CI, 1.9-5.0).ConclusionsThis study reveals Chinese college students' heavy reliance on OHI to manage their own and others' health without sufficient knowledge/skills to identify misinformation and disinformation. The apparent risky information-seeking behaviors of Chinese college students warrant the provision of regulated, accurate, and actionable health information; assurance of cybersecurity; and health information literacy promotion in colleges by concerned authorities.

Project description:BackgroundCollege students experience high levels of stress. Mindfulness meditation delivered via a mobile app may be an appealing, efficacious way to reduce stress in college students.ObjectiveWe aimed to test the initial efficacy and sustained effects of an 8-week mindfulness meditation mobile app-Calm-compared to a wait-list control on stress, mindfulness, and self-compassion in college students with elevated stress. We also explored the intervention's effect on health behaviors (ie, sleep disturbance, alcohol consumption [binge drinking], physical activity, and healthy eating [fruit and vegetable consumption]) and the feasibility and acceptability of the app.MethodsThis study was a randomized, wait-list, control trial with assessments at baseline, postintervention (8 weeks), and at follow-up (12 weeks). Participants were eligible if they were current full-time undergraduate students and (1) at least 18 years of age, (2) scored ≥14 points on the Perceived Stress Scale, (3) owned a smartphone, (4) were willing to download the Calm app, (5) were willing to be randomized, and (7) were able to read and understand English. Participants were asked to meditate using Calm at least 10 minutes per day. A P value ≤.05 was considered statistically significant.ResultsA total of 88 participants were included in the analysis. The mean age (SD) was 20.41 (2.31) years for the intervention group and 21.85 (6.3) years for the control group. There were significant differences in all outcomes (stress, mindfulness, and self-compassion) between the intervention and control groups after adjustment for covariates postintervention (all P<.04). These effects persisted at follow-up (all P<.03), except for the nonreacting subscale of mindfulness (P=.08). There was a significant interaction between group and time factors in perceived stress (P=.002), mindfulness (P<.001), and self-compassion (P<.001). Bonferroni posthoc tests showed significant within-group mean differences for perceived stress in the intervention group (P<.001), while there were no significant within-group mean differences in the control group (all P>.19). Similar results were found for mindfulness and self-compassion. Effect sizes ranged from moderate (0.59) to large (1.24) across all outcomes. A significant group×time interaction in models of sleep disturbance was found, but no significant effects were found for other health behaviors. The majority of students in the intervention group reported that Calm was helpful to reduce stress and stated they would use Calm in the future. The majority were satisfied using Calm and likely to recommend it to other college students. The intervention group participated in meditation for an average of 38 minutes/week during the intervention and 20 minutes/week during follow-up.ConclusionsCalm is an effective modality to deliver mindfulness meditation in order to reduce stress and improve mindfulness and self-compassion in stressed college students. Our findings provide important information that can be applied to the design of future studies or mental health resources in university programs.Trial registrationClinicalTrials.gov NCT03891810; https://clinicaltrials.gov/ct2/show/NCT03891810.

Project description:BackgroundNumerous studies have established that foreign language anxiety (FLA) has a significant impact on learners' language acquisition and performance. FLA is a unique form of anxiety that occurs in response to a certain circumstance. Even though a growing amount of research has extended to the examination of skill-based anxiety in specific, such as listening, speaking, reading, and writing, little used corresponding skilled-based FLA scales to assess learners' skill-based FLA at one group of learners. To fill a void in this line of research, the study aimed to explore learners' primary FLA by comparing their four language skill-specific FLAs with four different skill-based FLA scales. Additionally, we wished to investigate the variables that influence learners' FLA.MethodsAll participants in the study were first-year medical students. Individual instructors delivered and collected a total of 1023 questionnaires using an open questionnaire platform during normal English lessons in the mid-semester. SPSS 24.0 (Statistical Package for Social Science 24 version) was used to analyze all statistics. Internal validity tests were undertaken on each scale to ascertain the component structure of certain modified scales. The study employed the independent sample t-test and a statistical description to investigate students' major FLA and its variables.ResultsWith a mean value of 106.863, the predominant FLA arouses from English listening anxiety. English reading anxiety was the lowest, with a mean score of 62.726. Male and female students both demonstrated the greatest degree of FLA in English listening and the least anxiety in English reading. However, their mean difference was not statistically significant (t = 1.220). By comparing the mean scores for four skill-based FLAs across language proficiency groups, it became clear that the scores for the medium were much higher than the average, with average scores of ESA: 91.988, ELA: 106.864, EWA: 74.157, ERA: 62.726, respectively, and the higher-level group scored lower than the average. Students' prior English learning achievements are negatively connected with their FLA, with r values of -.207 (ELA), -.143 (EWA), and - .204 (ERA). The self-evaluation of students' English listening, writing, and reading abilities was considerably adversely connected with FLA, but the self-evaluation of their English-speaking abilities was favorably correlated with FLA.ConclusionA comparison of students' FLA revealed that the primary skill-based FLA is related to English listening anxiety. Regardless of gender or language proficiency level, FLA was mainly driven by foreign language listening anxiety in all individuals. Prior language achievement and students' self-evaluation are associated with their FLA.
