Prevalence of depression and its relation to stress level among medical students in Puducherry, India

Anxiety and depression during post covid-19 lockdown period among medical students, and it's relation with stress and smartphone addiction in India

OBJECTIVES

Medical profession, a competitive and ever-updating field which requires great commitment, imposes a stressful environment for students. Our study aimed to find the prevalence and factors associated with psychological illness.

METHODS

A cross-sectional analytical study was done among medical students in Puducherry. A stratified random sampling strategy was incorporated to achieve a calculated sample size of 384. The presence of anxiety and depression, perceived stress and addiction to the phone were assessed using the Hospital Anxiety and Depression Scale, Perceived Stress Scale, and Smartphone Addiction Scale - short version. Prevalence of anxiety and depression was summarized as a proportion with a 95 % confidence interval (CI). The prevalence ratio (PR) for the factors associated was estimated using log-binomial regression.

RESULTS

With the response from 383 students, the prevalence of anxiety and depression was 39.4 % (95 %CI: 34.5-44.3 %) and 26.6 % (22.2-31.1 %). Perceived stress was moderate in 68.2 % and high in 14 % of students. Higher age (aPR=1.49), female gender (aPR=1.22), tobacco or alcohol use (aPR=1.24), smartphone addiction (aPR=2.09) and high stress (aPR=1.93) were the predictors of anxiety among medical students in our study. Use of tobacco or alcohol (aPR=2.07), smartphone addiction (aPR=1.96) and high stress (aPR=1.72) were the predictors of depression.

CONCLUSIONS

Anxiety was more prevalent than depression among the medical students. Use of tobacco or alcohol, smartphone addiction and stress increase the risk of psychological morbidity. Medical training should have a module on coping mechanisms to overcome psychological illness and have better mental well-being.

Depression and Anxiety among Undergraduate Health Science Students: A Scoping Review of the Literature

Background: Health science students in post-secondary institutions experience high levels of depression and anxiety due to increased stress levels, workload, low socioeconomic status, and history of family mental illness, among other factors. Given the significant negative impact that depression and anxiety can have on undergraduate health science students, it is essential to understand the prevalence and correlation of these conditions in this population. In light of this, this scoping review aims to identify, document, and analyze the literature on the prevalence and determinants of anxiety and depression among undergraduate health sciences students and identify gaps in knowledge for future research. Methods: This scoping review was planned and executed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for the Scoping Reviews statement. A comprehensive and systematic search was carried out for five databases, namely MEDLINE, Scopus, EMBASE, CINAHL, and PubMed. Results: From the literature identified by our search strategy, the lowest prevalence for anxiety was 5.8%, and the highest was 82.6%, with a median of 44.25%. The prevalence of depression ranged from a high of 88.8% to a low of 2.1%, with a median value of 34.8%. Our analysis revealed that correlates of anxiety and depression among health science students include sociodemographic factors such as age, sex, gender, relationships, ethnicity, and family history, personal health conditions, and academic and socioeconomic issues. Conclusions: With the high incidence of anxiety and depression among health science students, there is an increasing need to find practical remedies to support these students. It is also essential for policymakers and university authorities to implement interventions such as supportive text messages and other strategies geared toward providing support and improving the psychological well-being of health science students.

A study of attitudes and experiences relating to alcohol use in a community of family farmers from Southern India

Problematic drinking is found to be common among Indian farmers. This study aims to improve our understanding of the causes, consequences, and culture surrounding drinking in Indian farming communities. 36 semi-structured interviews with male and female farmers were thematically analyzed. Problematic drinking in male farmers was found to significantly impact farmer's relationships, work, finances, and health, and to be related to spousal abuse and neglect. Drinking to cope with mental and physical pain was common, and stigma around drinking appears to be a barrier to social support. Implications for future research and treatment efforts for Indian farmers are discussed.

Competency-based medical education (CBME) curriculum and its effect on prevalence of anxiety, depression and stress amongst medical undergraduates

BACKGROUND

A growing body of literature now identifies higher levels of anxiety, depression, and stress among medical students as a distinct mental health domain. The competency-based medical education (CBME) curriculum was introduced to revamp the existing curriculum with an aim to garner constructive impact on the mental health of undergraduate medical students. As such, we sought to draw comparisons between the mental health of medical students, studying the old (2018 batch) and the new (2019 batch) medical education systems in India.

MATERIALS AND METHODS

We designed a survey that contained structured questions pertained to anxiety (HAM-A, GAD-7), depression (HAM-D, BDI), and stress (PSS) amongst medical undergraduate students of 2018 and 2019 batches at the Government Doon Medical College (GDMC), Dehradun, India.

RESULTS

Contrasting the 2018 and 2019 batches, the introduction of CBME resulted in a significant two-fold decrease in moderate anxiety, as exhibited by both HAM-A (6.0 vs 3.0, P = 0.016) and GAD-7 (3.5 vs 1.0, P = 0.037) scales, although no significant change in mild and severe anxiety, and overall depression (BDI: P = 0.05, HAM-D: P = 0.05) or stress (PSS: P = 0.86) was found.

CONCLUSION

The CBME system has made a significant impact on the mental health of undergraduate medical students for anxiety, albeit its effect on depression and stress remains equivocal. Future studies are warranted to compare the effect of CBME in other undergraduate and postgraduate courses across the country to help predict the psychological impact of the newfangled CBME education system.

Mental health and sleep habits during preclinical years of medical school

OBJECTIVES

The purpose of this non interventional study was to define changes in anxiety, depression, and sleep quality of medical students in their first two years of medical school while considering potential risk factors of self-reported chronic disease, sleep quantity, year of medical school and exercise habits. Since this study was ongoing during the COVID-19 pandemic, its effect was also evaluated.

PARTICIPANTS

/METHODS: A cohort of 197 medical students was evaluated longitudinally using survey methods to quantify changes from pre-medical school and summer break to each semester in medical school throughout years one and two. This study was performed from July 2019 through June 2021. Data was analyzed using Generalized Linear Mixed Models (GLMMs) on the numeric responses of General Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Sleep Quality (SQ-3) and Pittsburg Sleep Quality Index (PSQI). Additional assessments evaluated exercise habits, chronic disease, and impact of COVID-19 Pandemic. The COVID-19 Pandemic was evaluated directly in the model (pre- and post-COVID-19 period variable), and through additional questions on their perceived effect.

RESULTS

Depression, anxiety, and sleep habits displayed a cyclical change that was associated with the academic/seasonal cycle. The COVID-19 pandemic was never found significant. Medical students who had a chronic disease diagnosis and fewer hours of sleep had increased severity. Exercise did not play a role.

CONCLUSION

Based on our sample, the main driver for depression, anxiety, and poor sleep quality appears to be the academic/seasonal cycle, while the COVID-19 pandemic did not have an impact on mental health.

Prevention and Treatment of Cardiovascular Diseases with Plant Phytochemicals: A Review

Cardiovascular diseases (CVDs) are the world's leading killers, accounting for 30% deaths. According to the WHO report, CVDs kill 17.9 million people per year, and there will be 22.2 million deaths from CVD in 2030. The death rates rise as people get older. Regarding gender, the death rate of women by CVD (51%) is higher than that of men (42%). To decrease and prevent CVD, most people rely on traditional medicine originating from the plant (phytochemicals) in addition to or in preference to commercially available drugs to recover from their illness. The CVD therapy efficacy of 92 plants, including 15 terrestrial plants, is examined. Some medicinal plants well known to treat CVD are, Daucus carota, Nerium oleander, Amaranthus Viridis, Ginkgo biloba, Terminalia arjuna, Picrorhiza kurroa, Salvia miltiorrhiza, Tinospora cordifolia, Mucuna pruriens, Hydrocotyle asiatica, Bombax ceiba, and Andrographis paniculate. The active phytochemicals found in these plants are flavonoids, polyphenols, plant sterol, plant sulphur compounds, and terpenoids. A general flavonoid mechanism of action is to prevent low-density lipoprotein oxidation, which promotes vasodilatation. Plant sterols prevent CVD by decreasing cholesterol absorption in the blood. Plant sulphur compound also prevent CVD by activation of nuclear factor-erythroid factor 2-related factor 2 (Nrf2) and inhibition of cholesterol synthesis. Quinone decreases the risk of CVD by increasing ATP production in mitochondria while terpenoids by decreasing atherosclerotic lesion in the aortic valve. Although several physiologically active compounds with recognized biological effects have been found in various plants because of the increased prevalence of CVD, appropriate CVD prevention and treatment measures are required. More research is needed to understand the mechanism and specific plants' phytochemicals responsible for treating CVD.

Bullying as a Risk Factor of Depression on Undergraduate Health Students

Depression is a serious health problem that needs to be treated early so that it does not get worse in the future. Bullying can cause a mental health problem on students. This study aims to analyze the relationship between bullying and depression among undergraduate health students. This was an observational study with a cross-sectional design. Respondents filled out questionnaires online using the Google Form application. A total of 246 undergraduate health students participated in this study. Multivariate logistic regression was used to analyse the data. There was a relationship between bullying and the incidence of depression in undergraduate health students (AOR: 2.158 (95% CI: 1.050-4.435)) after being controlled by physical attacked, close friends, loneliness, and smartphone addiction. This study proves that bullying is a risk factor for depression. Prevention of bullying is important to prevent depression. Handling and prevention are done by involving peer support from students through peer-counselor or peer-educator programs. Students with severe depression need to be treated further through an appropriate referral system.

Stress, Burnout, and Coping among First-Year Medical Undergraduates

Background and Objectives  Stress, burnout, and coping have been found to be interlinked with each other. Several adverse psychological outcomes have been associated with stress and burnout. Improving coping can decrease the stress and burnout. There is limited literature on perceived stress, coping, and burnout among first-year medical undergraduates from India. With this background, the study aimed to assess perceived stress, coping, and burnout among first-year medical undergraduates. Methods  It was a cross-sectional study assessing 100 undergraduates studying in the first year of medical school. Medical Students Stressor Questionnaire, Brief COPE questionnaire, and Maslach burnout inventory-student survey were applied for assessment of perceived stress, burnout, and coping, respectively. Socio-demographic profile was assessed by a semi-structured proforma. Results  Majority of students reported facing moderate level of stress in most of the domains, with stress being the highest for the academic aspects and least for social-related and drive- and desire-related areas. The stress was significantly greater in female students. Burnout was identified in 62% students by two-dimensional criteria and 30% by three-dimensional criteria. Among the coping strategies, active coping was most commonly used and substance use was less commonly used. No differences were found in coping between males and females except for active coping, which was significantly better in females. Conclusion  The stress was of moderate degree in majority of students and academic stress was the most common stress. Burnout was present in at least one-third of the students. However, majority of the students practiced active coping.

Suicide among Indian doctors

BACKGROUND

India has one of the largest numbers of doctors in the world. It is estimated that more than 1 million doctors are in India. Every year more than 80,000 medical students graduate as doctors from 529 medical colleges in India. Medical profession is considered as more stressful, but mental health is still a subject of taboo in medical profession in Indian context. Doctors have higher suicide risk, 2.5 times more than the general population. In the United Kingdom, 430 doctors committed suicide between the years 2011 and 2015. Even though suicide among doctors is reported in Indian media, there is hardly any scientific study that has looked into the suicide among Indian doctors because of many hurdles in the collection of information.

MATERIALS AND METHODS

All the Indian newspaper that are published in English and are available in the online platform were scrutinized on doctors suicide report from the year 2016 March to 2019 March.

RESULTS

Thirty suicides were reported between 2016 March and 2019 March, out of which 18 were female and 12 male. More than 80% were younger than 40 years. Twenty-two were from medical education institutions. Seventeen were from south India and 13 from North India. Eight were MBBS students and ten were postgraduate students. Among subspecialties, six doctors were from Anesthesia. Seventeen used hanging as a method for suicide, eight used medications, and five jumped from building to end life. Nineteen of suicide reports about doctors mentioned that they were depressed.

CONCLUSION

Suicide among Indian doctors is concern. Majority are young undergraduate and postgraduate medical students. Female doctors were more than male doctors. Most doctors were reported to be depressed and used lethal method such as hanging and medications.

Prevalence of Psychological Distress among Undergraduate Medical Students: A Cross-Sectional Study

Background:

Stressful environment in medical school often has a negative effect on students' psychosocial well-being. An in-depth understanding of how medical students experience psychological distress and coping is necessary for the prospective students.

Objectives:

To estimate the prevalence of psychological distress among undergraduate medical students and its association with some demographic factors.

Materials and Methods:

A cross-sectional descriptive study was conducted among 380 medical students in the University of the West Indies, Saint Augustine. The questionnaires used in this study consisted of two components – (i) the demographic information that required participants to provide their gender, age, year of study, and nationality and (ii) Depression, Anxiety, and Stress Scale-21 items to measure the levels of psychological distress among participants.

Results:

Anxiety was the most prevalent psychological distress among medical students, with 63% of them having anxiety symptoms. Depression was found to be the second most common psychological distress, with a prevalence of 51%, while 48% of the students suffered from stress. In further analysis, we found that Trinbagonian students were more depressed than the students from Caribbean Community and other nationality. Higher anxiety score was significantly associated with gender and age of the students. There was a significant association between students from different age groups and level of stress.

Conclusions:

A considerable number of students studying medicine are suffering from psychological distress. Intervention programs to address the mental health problems of such students should be initiated.

First-year French medical students consume antidepressants and anxiolytics while second-years consume non-medical drugs

BACKGROUND

First year exams are a major source of stress amongst first-year medical students.

OBJECTIVE

To explore antidepressant and anxiolytic consumption and addictive behavior of medical students before and after exams.

METHODS

Medical students of the 35 French medical schools were recruited through mailing lists and social networks between December 2016 and May 2017 and completed online Internet anonymized questionnaires.

RESULTS

Overall, 4345 medical students were included (3051 first year vs. 1294 second year). In multivariate analyses, compared to those in the first year of medicine, second year students were found to have lower anxiolytic (adjusted odd ratio (aOR)=0.56, p = 0.01) and antidepressant consumption (aOR=0.21, p<0.0001) but higher psychiatric follow-up (aOR=1.95, p<0.0001) after adjustment for age, gender and relationship status. Whilst second year students reported slightly higher quality of life (especially for mental health), they also reported more daily tobacco smoking (aOR=1.78, p<0.0001), more cannabis use disorders (aOR=2.37, p<0.0001), hazardous drinking (aOR=3.61, p<0.0001), and alcohol dependence (aOR=3.66, p<0.0001). Second year medical students reported fewer difficulties relating to studying in comparison to first year students (aOR=0.60, p<0.0001) yet they reported a higher rate of recreational drugs use with a variety of reasons including self-treatment of anxiety; disinhibition and to copy their peers (all p<0.05).

LIMITS

These results should be confirmed by longitudinal studies.

CONCLUSION

First year medical students who are faced with challenges relating to studying consume more antidepressants and anxiolytics, whilst second year students have a higher consumption of recreational drugs for a range of reasons. This suggests that the first two years at medical school are an important contributor to adverse mental health and therefore present a window of opportunity for preventative intervention.

Prevalence and Factors Associated with Depression among Medical Students at Makerere University, Uganda

BACKGROUND

Depression affects about a third of medical students worldwide. There is paucity of data on depression among medical students in Uganda. The purpose of this study was to establish the prevalence and factors associated with depression among medical students at Makerere University College of Health Science (MakCHS), Uganda.

METHODS

A cross-sectional study was conducted among students pursuing a Bachelor of Medicine and Surgery at MakCHS in May and July 2019. Students were enrolled by consecutive sampling, both online using Google Forms and in person for those unable to access internet. The self-reported Patient Health Questionnaire 9 (PHQ9) was administered to assess depression, defined as a PHQ9 score ≥10. Microsoft Excel 2016 and Stata 16 were used for data analysis.

RESULTS

Overall, 331 valid responses (mean age 23.1±3.3 years) were submitted (response rate 93.8%). In a majority of participants, the prevalence of depression was 21.5% (n=71) of which 64.1% had moderate depression (n=50). On bivariate analysis, year of study, worrying about academic performance, and lectures were significantly associated with depression. On multivariate analysis, worrying about academic performance (aOR 2.52, 95% CI 1.50-4.22; P<0.001) and lectures (aOR 1.89, 95% CI 1.11-3.22; P=0.018) were significantly associated with depression.

CONCLUSION

Depression affects a significant number of medical students at MakCHS. About one in five medical students have depression. Year of study and academic performance were significantly associated with depression. Efforts aimed at identification and evaluation of students at risk, administering appropriate interventions, and follow-up of affected students are vital. Analytical studies aimed at establishing the causative factors and the effects of depression on medical students are recommended.

A systematic review of depression and anxiety in medical students in China

BACKGROUND

Medical students in China face severe depression and anxiety because of their difficult circumstances, such as the long length of schooling, academic pressure, and the stress of clinical practice. Although there have been many empirical studies about depression or anxiety in medical students in China, no previous studies have conducted a related systematic review about this topic in English. This analysis can convey the general findings from China to other areas of the world.

METHODS

A systematic review and meta-analysis of depression or anxiety in medical students and related determinants were conducted. Three Chinese and three English databases were searched for the review, with no restrictions on language. Articles published between January 1, 2000 and April 1, 2018 were included.

RESULTS

Twenty-one articles investigating a total of 35,160 individual Chinese medical students were included in this review. The prevalence of depression ranged from 13.10 to 76.21% with a mean of 32.74%, and the prevalence of anxiety ranged from 8.54 to 88.30% with a mean of 27.22%. Based on the meta-analysis, gender, grade level, residence, satisfaction with current major and monthly household income per capita were significantly associated with depression. Grade level and satisfaction with current major were significantly associated with anxiety. Other risk factors were identified and described using a narrative approach.

CONCLUSION

The mean prevalence of depression was 32.74% amongst medical students in China, whereas the mean prevalence of anxiety was 27.22%. The determinants of depression and anxiety included individual factors, social and economic factors, and environmental factors. More measures should be taken towards at-risk medical students based on the identified risk factors.

Psychiatric and psychological follow-up of undergraduate and postgraduate medical students: Prevalence and associated factors. Results from the national BOURBON study

BACKGROUND

Physicians are at risk of burnout, anxiety and depression. Prevention is needed from the beginning of the medical studies to detect early poor mental health outcomes.

OBJECTIVE

To determine the prevalence and associated of psychiatric or psychological follow-up in a national sample of undergraduate and postgraduate medical students (UPMS).

METHODS

UPMS of the 35 French Medicine faculties were recruited through mailing lists and social networks between December 2016 and May 2017 and fulfilled Internet anonymised questionnaires.

RESULTS

Overall, 10,985 UPMS were included in the present study (2165 (19.7%) postgraduate, 31.6% males, mean aged 21.8 years). Overall, 1345 (12.2%) were followed-up by a psychiatrist and/or a psychologist, 20.5% of them were regular anxiolytic consumers and 17.2% of them were regular antidepressant consumers. In multivariate analyses, being followed-up by a psychiatrist and/or psychologist was associated with older age (aOR = 1.2[1.2-1.2], p < 0.0001), female gender (aOR = 0.5[0.5-0.7], p < 0.0001), current alcohol use disorder (aOR = 1.3[1.3-1.5], p < 0.0001), higher anxiolytic (aOR = 3.1[2.5-3.7],p < 0.0001) and antidepressant (aOR = 11.7[7.6-18.0],p < 0.0001) consumption, and with lower self-reported general health, social functioning and mental health quality of life (all aORs = 0.9, all p < 0.05). The UPMS followed-up by psychiatrist and/or psychologist reported to have been more frequently exposed to sexual assault (5.1% vs. 0.9%, aOR = 2.5[1.3-4.7], p < 0.0001), domestic violence (3.3% vs. 0.8% aOR = 2.1[1.2-4.0], p = 0.01) and parents divorce (11% vs. 6.4%, aOR = 1.5[1.2-1.9], p = 0.001). Students followed-up by a psychiatrist and/or psychologist reported more frequently to seek alleviating anxiety (aOR 1.9[1.6-2.3], p < 0.0001), depression (aOR 1.7[1.3-2.1],p < 0.0001), coping with studies difficulties (aOR 1.5[1.2-1.8],p < 0.0001), experiencing more stress at hospital (aOR = 2.3[1.6-3.5],p < 0.001) and more burnout syndrome (aOR = 1.4[1.1-1.8], p = 0.03).

CONCLUSIONS

Around 12% of UPMS are followed-up by a psychiatrist and/or a psychologist. These students reported higher antidepressant and anxiolytic consumption, psychic suffering and altered quality of life, associated with professional pressure and personal issues. Public health programs should be developed to help these students through their studies to prevent later mental /addictive issues and professional suffering. Improving UPMS mental health may also improve the later quality of care of their patients and global stress at hospital.

Prevalence and correlates of depression among male medical students and interns in Albaha University, Saudi Arabia

Background:

Depression in medical students and interns appear higher than the general population, with evidence of mental health deterioration over a period of medical training.

Objectives:

To estimate the prevalence and evaluate the predictors of depression among male medical students and interns, Albaha University, Saudi Arabia.

Subjects and Methods:

A cross-sectional analytic study was conducted which includes a representative stratified random sample with the proportional allocation of male medical students and interns, College of Medicine, Albaha University (2017–2018). A questionnaire included sociodemographic characteristics of the participants as well as a medical and family history of depression, medical or psychiatric illness, abuse or violence, and the major traumatic event was utilized. In addition, the validated reliable Arabic version of Becks Depression Inventory (BDI) questionnaire was used to screen for depression.

Results:

The study included 161 medical students and 21 interns. Their age ranged between 19 and 26 years with a mean of 22.03 ± 1.94 years. Majority of the participants (98.9%) were Saudis and singles (84.6%). The prevalence of depression, based on the BDI scale, was 53.8%; it was mild in 25.8% and severe or extreme in 4.4% of the participants. No factor was significantly associated with depression. However, severe or extreme depression was more reported among students/interns with a history of domestic abuse or violence and those who had a history of major trauma or psychiatric event, P < 0.001.

Conclusion:

Depression is a common problem among male medical students and interns in AlBaha University, with no difference according to demographics, smoking history, family history of depression, history of chronic medical or psychiatric illness, history of domestic/violence abuse, and history of major trauma or psychiatric event.

The effects of fluoxetine on the human adipose-derived stem cell proliferation and differentiation

Fluoxetine is one of the most commonly used antidepressants. Fluoxetine could prevent the mesenchymal stem cell differentiation in lung fetus of rat. Moreover, the mesenchymal stem cells are also present in adult tissues. Therefore, in the current study, we aimed to investigate the effects of fluoxetine (FLX) on both proliferation and adipogenic/osteogenic differentiation of human adipose-derived stem cells (ADSCs). After culturing of human ADSCs, these cells were treated with two concentrations of FLX (10 and 20 μm). Then, cells were differentiated by adding osteogenic and adipogenic media. The effect of FLX on human ADSCs proliferation was evaluated by MTT assay. Fluoxetine role on adipogenic and osteogenic differentiation of human ADSCs was analyzed by oil red and alizarin red staining and RT-PCR reaction. According to MTT assay, FLX showed a time- and concentration-dependent proliferation response and eventually decreased human ADSCs proliferation. RT-PCR analysis indicated that FLX significantly diminished the expression of osteogenesis-related genes such as RUNX2 and alkaline phosphatase (ALP). Data also revealed a significant reduction in the expression of peroxisome proliferator-activated receptor γ (PPARγ) and fatty acid-binding protein (FABP) (specific genes of adipogenic lineage). In addition, FLX decreased mineralized matrix and the amount of lipid droplets in human ADSCs by staining methods. Our observation demonstrated that the effects of FLX may be time-dependent. This drug possesses an increasing phase in proliferation and survival of human ADSCs (first 24 h) following a decreasing phase (after 48 h). Moreover, FLX could attenuate both osteogenic and adipogenic differentiation of human ADSCs.
