Personality Traits and Changes in Health Behaviors and Depressive Symptoms during the COVID-19 Pandemic: A Longitudinal Analysis from Pre-pandemic to Onset and End of the Initial Emergency Conditions in Finland

Chrononutrition in the Prevention and Management of Metabolic Disorders: A Literature Review

BACKGROUND

The concept of time-restricted eating (TRE) or time-restricted feeding (TRF) promotes daily periods of feeding and fasting to determine whole-body physiology. Chronic misalignment of circadian rhythms or chrono-disruption is related to an increased risk of diverse metabolic disorders. The progression of non-communicable diseases seems to be affected by the timing of meals. As a result, intermittent fasting is a promising approach for their management. The aim of the present literature review is to examine and scrutinize the TRE protocols in the fields of prevention and management of metabolic disorders.

METHODS

This is a thorough literature review of the reported associations among circadian rhythm, metabolic disorders, diabetes mellitus, obesity, TRE, TRF, dietary habits, circadian disruption, cardiovascular diseases, atherosclerosis, and non-alcoholic fatty liver to find the already existing clinical studies from the last decade (2014-2024) in the most precise scientific online databases, using relevant specific keywords. Several inclusion and exclusion criteria were applied to scrutinize only longitudinal, cross-sectional, descriptive, and prospective clinical human studies.

RESULTS

The currently available clinical findings remain scarce and suggest that chrononutrition behaviors such as TRE or TRF may promote several metabolic benefits, mainly in body weight control and fat loss. Improvements in glucose levels and lipid profiles are currently quite controversial since some clinical studies show little or no effect. As far as liver diseases are concerned, the efficacy of intermittent fasting seems to be stronger in the management of non-alcoholic fatty liver disease due to body weight decline and fat loss.

CONCLUSIONS

Even if there has been a gradual increase in clinical studies in the last few years, providing promising perspectives, currently, there is no conclusive evidence for the role of chrononutrition in metabolic disorders. Future studies should be well-designed with longer duration and larger sample sizes. Moreover, it is important to examine the best timing of the eating window and its feasibility.

Nutritional changes during the COVID-19 pandemic: a rapid scoping review on the impact of psychological factors

COVID-19 and the resulting measures to curb the spread of the virus have significantly changed our lives, including our nutritional choices. In this rapid scoping review an overview is provided of what psychological factors may be associated with peoples' eating behaviour during COVID-19 restrictions. Relevant literature was identified using PubMed, PsycInfo, CINAHL and MEDLINE databases from 2019 onwards. For included studies, information on study characteristics, eating behaviours, and psychological factors were extracted. 118 articles were included, representing 30 countries. Findings indicated that most people consumed more and unhealthy food in times of COVID-19 restrictions, while some consumed less but often for the wrong reasons. Several psychological factors, related to (1) affective reactions, (2) anxiety, fear and worriers, (3) stress and (4) subjective and mental wellbeing were found to be associated with this increase in food consumption. These outcomes may help to be better inform future interventions, and with that, to be better prepared in case of future lockdown scenarios.

Determinants of depressive symptoms increase in older persons during the COVID-19 pandemic: evidence from Czech cohort study using repeated assessments

BACKGROUND

Numerous studies reported higher levels of mental health issues during the COVID-19 pandemic but only a minority used repeated measurements. We investigated change in depressive symptoms in the Czech ageing cohort and the impact of pre-existing and COVID-19-related stressors.

METHODS

We used data on 2853 participants (mean age 73.4 years) from the Czech part of the prospective Health, Alcohol and Psychosocial factors In Eastern Europe cohort that participated in postal questionnaire surveys before (September 2017-June 2018) and during the pandemic (October 2020-April 2021). Participants reported their depressive symptoms using the Centre for Epidemiological Studies-Depression Scale including 10 (CESD-10) tool. A principal component analysis (PCA) was used to create representative components of the pandemic-related stressors. The impact of the stressors on change in depressive symptoms was tested using multivariable linear regression, after adjustment for age and potential confounders.

RESULTS

Three patterns of the pandemic-related stressors ('financial stressors', 'social and perception stressors' and 'death and hospitalisation stressors') were extracted from the PCA. The mean CESD-10 score increased from 4.90 to 5.37 (p<0.001). In fully adjusted models, significantly larger increases in depression score were reported by older people (β=0.052; p=0.006), those with poor self-rated health (β=0.170; p<0.001), those who experienced death or hospitalisation of a close person (β=0.064; p<0.001), social deprivation (β=0.057; p<0.001), delays in healthcare (β=0.048; p=0.005) and those who suffered from COVID-19 (β=0.045; p=0.008).

CONCLUSION

This study confirms an increase in depressive symptoms in older persons during the pandemic and identified several pandemic-related risk factors suggesting that public health policies should address this vulnerable group by adopting the preventing strategies.

Impact of the COVID-19 lockdown on lifestyle behaviors and their association with personality among adults in Qatar: A cross-sectional study

The coronavirus pandemic (COVID-19) resulted in lockdowns and social distancing measures enforced by governments around the world. This study aimed to identify changes in adherence to the Mediterranean diet (MD) and physical activity (PA) and associations with personality during lockdown. Using a cross-sectional design, a convenient sample of 543 adults in Qatar completed an online questionnaire consisting of validated tools to measure adherence to MD (MEDAS questionnaire, score ranges 0–13), PA (IPAQ, assessing light, moderate high intensity PA) and personality (BFI-10, categorizing individuals’ personalities). The majority of the participants were female (89%), aged between 21 and 29 years (45%). The overall MD adherence decreased during lockdown (5.9 vs. 6.1, p < 0.001). There was an increase in olive oil (9% vs. 12%; p < 0.001), vegetables (54.3% vs. 58.7%; p = 0.005), legumes (11.8% vs. 15.3%; p = 0.007), sofrito (70.9% vs. 77.3%; p < 0.001) and fat (45.9% vs. 53.8%; p < 0.001) consumption and a decrease in fresh fruit (39.4% vs. 15.8%; p < 0.001) and fish/seafood (5.9% vs. 3.9%; p = 0.0035) consumption during lockdown. Met-min/week values of total PA (1330.5 vs. 1836.7), vigorous activity (711.5 vs. 867.4), moderate activity (208.3 vs. 301.3), and walking (410.7 vs. 668.0) all decreased during lockdown (p < 0.001, p = 0.010, p = 0.010 p < 0.001, respectively), while sitting increased (3837.3 vs. 2896.4 p < 0.001). The extraversion personality dimension had a higher MD adherence (p = 0.039) compared to agreeableness before lockdown. No changes in MEDAS scores were observed during lockdown in those with high levels of openness. Openness was positively associated with all PA (p = 0.027), including walking (p = 0.026), and negatively associated with sitting (p = 0.038) before lockdown, while participants with high scores for neuroticism were less likely to be sitting during lockdown (p = 0.042). The findings can be used to guide the development of appropriate personality-tailored lifestyle interventions.

Changes in older people's quality of life in the COVID-19 era: a population-based study in Finland

PURPOSE

We investigated how quality of life (QoL) changed between 2018 and 2020, and how its related factors, i.e., communication with friends and family, loneliness, and sleeping difficulties changed amid the early-phase COVID-19 pandemic among Finnish older people.

METHODS

This study utilizes data from a repeated cross-sectional, population-based FinSote survey in 2018 and 2020. Participants were community-dwelling people aged 75 years or older (N = 9781 in 2018 and N = 9919 in 2020). QoL was assessed with the EUROHIS-QoL-8 scale. Changes in QoL-related factors were self-evaluated in 2020. Statistical methods included t test, Cohen's D, and chi-square test. To identify potential risk groups, all analyses were stratified by socio-demographic features including sex, age, economic deprivation, living alone, and difficulties in Instrumental Activities of Daily Living (IADL).

RESULTS

QoL improved slightly from 2018 to 2020 (means 3.68 and 3.81, respectively). Only those reporting economic deprivation demonstrated a slight decrease in QoL (3.24 vs. 3.14). Of respondents, 63% reported having less communication with friends and family, 42% having felt lonelier, and 20% having more sleeping difficulties amid the pandemic. Negative changes were more often reported by women, the oldest old, those living alone, reporting economic deprivation, or manifesting IADL difficulties.

CONCLUSION

Finnish older people's QoL was not affected as much as expected amid the pandemic, although some population groups were, however, more susceptible to the negative effects of the pandemic on QoL-related factors. Results imply that various socio-demographic features may shape the effects of a global pandemic and its control measures on wellbeing.

Physical Activity and Mental Health Declined during the Time of the COVID-19 Pandemic: A Narrative Literature Review

(1) Introduction: Mental health (MH) and physical activity (PA) share a bi-directional relationship, but most studies report MH as the outcome. With diminishing pandemic-related MH, this review examines the impact of diminished MH on PA. (2) Methods: This narrative literature review included 19 empirical studies published since the COVID-19 pandemic. Electronic databases such as MEDLINE, PsycINFO, and CINAHL were searched for English language articles in peer-reviewed journals using equivalent index terms: "anxiety", "depression", "stress", "mental health", "exercise", "activity", "COVID-19", "coronavirus", and "2019 pandemic". The search reviewed 187 articles with double-rater reliability using Covidence. A total of 19 articles met the inclusion criteria. (3) Results: MH themes that impacted PA were depression and/or anxiety (n = 17), one of which identified inadequate coping and excessive pandemic stress (n = 2). In addition, women are more likely to suffer diminished MH and reduced PA throughout the pandemic. (4) Conclusion: Current research suggests that individuals with pre-pandemic MH episodes are correlated with more effective coping skills and fewer adverse effects from COVID-19 than expected. As we emerge from this pandemic, equipping all individuals, especially women, with positive coping strategies may accelerate a seamless return to PA.

Big Five Traits as Predictors of a Healthy Lifestyle during the COVID-19 Pandemic: Results of a Russian Cross-Sectional Study

The healthy lifestyle of people around the world has changed dramatically during the COVID-19 pandemic. The personality risk factors for these processes from around the world remain understudied. This study aimed to examine the associations of the Big Five traits with a healthy lifestyle during the COVID-19 pandemic. In a cross-sectional study, data from 1215 Russian university students were analyzed. Participants completed the Big Five Inventory-10 and Short Multidimensional Inventory Lifestyle Evaluation. The results showed that personality traits predicted many dimensions of a healthy lifestyle during the COVID-19 pandemic. Diet and nutrition were positively predicted by extraversion, agreeableness, and conscientiousness, and it was negatively predicted by neuroticism. Substance abuse was positively predicted by agreeableness and conscientiousness, and it was negatively predicted by extraversion. Physical activity was positively predicted by extraversion and conscientiousness, and it was negatively predicted by neuroticism. Stress management was positively predicted by extraversion and conscientiousness, and it was negatively predicted by neuroticism. Restorative sleep was positively predicted by extraversion and conscientiousness, and it was negatively predicted by neuroticism. Social support for healthy practices was positively predicted by extraversion, agreeableness, and conscientiousness. Environmental exposures were positively predicted by extraversion, and neuroticism was positively and negatively predicted by conscientiousness. Our findings may be useful for further exploration of personality risk factors for healthy practices in challenging life circumstances.

Mental Health Consequences of COVID-19 Pandemic Period in the European Population: An Institutional Challenge

The worldwide spread of SARS-CoV-2 has been responsible for an infectious pandemic, with repercussions on socio-economic aspects and on the physical and mental health of the general population. The present systematic review aimed to evaluate the data belonging to the European framework, analyzing the population by age group. Original articles and reviews on the state of mental health of the general European population have been researched starting from 2021. Initially, a total of 1764 studies were found, among which a total of 75 were selected. Youth were the age group most affected by pandemic consequences on mental health, with emotional and behavioral alterations observed from a third to more than a half of children and adolescents examined. Among both adolescents and adults, the female gender had a higher prevalence of psychopathological symptoms. The main risk factors were poor social support, economic difficulties, and, in particular, unemployment or job changes. Additional individual risk factors were the perception of loneliness, the presence of pre-pandemic mental illness/distress, and some personality traits, such as neuroticism, impulsiveness, and the use of maladaptive coping strategies. Unexpectedly, the elderly maintained good resilience towards change, even if a stress factor was represented by the feeling of loneliness and poor social contact. As regards suicidal behaviors, among adolescents, there was an increase in attempts of 25%, with a greater risk for the female gender. This risk increased also among adults, in association with symptoms of anxiety and depression, and poor socio-environmental conditions. In conclusion, some population groups were found to be at greater risk of psychological burden during pandemic waves, thus representing priority targets for socio-health interventions.

Change in Neuroticism and Extraversion among Pre-University Education Employees during the COVID-19 Pandemic

Background and objectives: Since the first reports of SARS-CoV-2 infection cases in China, the virus has rapidly spread to many countries, including Romania. In Romania, schools were closed in March 2020 to prevent the virus from spreading; since then, they have been sporadically opened, but only for a short time. Teachers had to adopt online education methods, experiencing real difficulties in their attempts to maintain high-quality teaching, as a result of social distancing from students and colleagues. The current study aimed to evaluate the burden on the neuroticism states of employees in the pre-university education system during the COVID-19 pandemic. Materials and Methods: A prospective study was conducted, in which personality trait data from 138 employees were collected via a questionnaire (EPI, Eysenck Personality Inventory), which measured extraversion–introversion and neuroticism scores before and during the COVID-19 pandemic. Initially, 150 subjects were invited to participate in the study, although 12 of them refused to participate. Based on the questionnaire not being fully filled in a further three subjects were excluded from the study, leaving a total of 135, of which 115 were woman and 20 were men. Results: The results demonstrate that the subjects included in the study expressed higher neuroticism during the COVID-19 pandemic than in the pre-pandemic period. This change could promote more stress and depression symptoms. Subjects with high school education had significantly lower neuroticism scores over time than those with university education (p = 0.006). Furthermore, we found extraversion scores to be statistically significant in our population (p = 0.022). Conclusion: The gender and living environment of the teachers were not significantly associated with the reduction in the extraversion score, but were more frequently found among older persons and in subjects without higher education. Subjects of Hungarian ethnicity had lower extraversion scores than those of Romanian ethnicity.

The Effect of Personality on Chrononutrition during the COVID-19 Lockdown in Qatar

The COVID-19 lockdown has had a significant impact on people’s lives worldwide. This study aimed to investigate the effect of personality on chrononutrition during the COVID-19 lockdown. Using a cross-sectional design, a convenient sample of 543 adults in Qatar completed an online questionnaire using validated tools to assess personality and chrononutrition behaviors during the first COVID-19 lockdown. Participants scoring high in openness were more likely to eat at night (mean difference (MD) = 0.41, 95% confidence interval (CI): 0.10, 0.72) compared to those scoring high in agreeableness, while those scoring high in extraversion and openness had a shorter eating window (MD = −76.6, 95%CI: −146.3, −6.93 and MD = −29.8, 95%CI: −56.5, −3.01, respectively). Participants high in extraversion had longer evening latency (MD = 66.3, 95%CI: 25.4, 107.3) and evening eating (MD = −62.0, 95%CI: −114.0, −9.0) compared those high in agreeableness. Participants high in conscientiousness showed evidence of first eating event misalignment during the weekend (MD = 22.0, 95%CI: 0.15, 43.9) and last eating event misalignment during weekdays (MD = −27.8, 95%CI: −47.3, −8.41) compared to those high in agreeableness. Lastly, participants high in openness showed evidence of eating window misalignment during the weekend (MD = 30.6, 95%CI: 5.01, 56.2). This study suggests that personality traits can inform personalized nutritional approaches when aiming for healthy habits during unexpected periods, such as the COVID-19 pandemic.

More Depressive Symptoms, Alcohol and Drug Consumption: Increase in Mental Health Symptoms Among University Students After One Year of the COVID-19 Pandemic

Background: As the majority of studies examining mental health during the pandemic are cross-sectional, little is known about the changes in mental health during the pandemic, especially in university students. Most studies indicate a worsening of mental health conditions. This study aimed to evaluate the mental health status of German university students during the third wave of the pandemic in 2021 and to compare the results to a sample of a congruent cross-sectional study from 2020. Methods: Two cross-sectional and anonymous online surveys among university students were conducted (first survey: July-August 2020, N = 3,382; second survey: March-April 2021, N = 5,642). Mental health status was assessed with standardized measures (depressive symptoms, alcohol and drug consumption, and eating disorder symptoms), and social and emotional aspects of the COVID-19 pandemic were assessed. In addition to descriptive statistics and group comparisons of the two survey samples from 2020 and 2021, respectively, risk and protective factors related to mental health were analyzed. Results: There were significant differences in severities of depressive symptoms and alcohol and drug consumption between the two online surveys from 2020 and 2021. Findings suggest an increase in the severity of depressive symptoms as well as alcohol and drug consumption. Significantly more respondents reported suicidal ideation in the survey from 2021. Lower self-efficacy, less social support and lower resilience as well as higher perceived stress and more loneliness were reported by the participants of the survey from 2021 compared to 2020. Regarding factors predicting mental health symptoms, being female was a positive predictor for hazardous alcohol use and anorexia nervosa in comparison to men. Further, younger age, being diverse, higher perceived stress and loneliness were positive predictors for all mental health outcomes. Conclusion: This study reveals an increase in severities of depressive symptoms, including suicidal ideation, drug and alcohol consumption among students. Being diverse, younger age, higher perceived stress and loneliness were mutual risk factors for higher depressive and eating disorder symptoms as well as alcohol consumption. Universities and health care policy should recognize and address mental health issues of young adults during ongoing times of crisis and invest in easy-to-access interventions.
