Sleep and Lifestyle Habits of Medical and Non-Medical Students during the COVID-19 Lockdown.

It has been shown that the measures of social distancing and lockdown might have had negative effects on the physical and mental health of the population. We aim to investigate the sleep and lifestyle habits as well as the mood of Croatian medical (MS) and non-medical students (NMS) during the COVID-19 lockdown. The cross-sectional study included 1163 students (21.6% male), whose lifestyle and sleep habits and mood before and during the lockdown were assessed with an online questionnaire. The shift towards later bedtimes was more pronounced among NMS (~65 min) compared to MS (~38 min), while the shift toward later wake-up times was similar in both MS (~111 min) and NMS (~112 min). All students reported more frequent difficulty in falling asleep, night-time awakenings and insomnia (p < 0.001) during lockdown. A higher proportion of MS reported being less tired and less anxious during lockdown compared to pre-lockdown (p < 0.001). Both student groups experienced unpleasant moods and were less content during lockdown compared to the pre-lockdown period (p < 0.001). Our results emphasize the need for the promotion of healthy habits in the youth population. However, the co-appearance of prolonged and delayed sleep times along with decreased tiredness and anxiety among MS during lockdown reveals their significant workload during pre-lockdown and that even subtle changes in their day schedule might contribute to the well-being of MS.

Anxiety among pediatric asthma patients and their parents and quick-reliever medication use: The role of physical activity parenting behaviours.

Background: Clinical guidelines recommend the identification of asthma comorbidities, especially treatable problems such as parental behaviours and child and parent anxiety. Purpose: We aimed to (1) explore associations of asthma severity with child and parent state anxiety, trait anxiety, and asthma-related anxiety as well as with caregiver behaviours around physical activity and (2) explore if caregiver behaviours around physical activity were associated with use of inhaled ß-Agonists when symptomatic, and with child and parent anxiety. Patients and methods: Patients ages 3-17 years with asthma (n = 72) and their parents were recruited from the Pulmonology-Allergology Pediatric clinic University Hospital Centre Split in Split, Croatia during 2021. During a clinical visit, the pharmacological regimen was assessed and spirometry was performed. Children completed the State-Trait Anxiety Inventory for Children (STAI-C) and the Youth Asthma-Related Anxiety Scale (YASS). Parents completed the State-Trait Anxiety Inventory (STAI), the Parent Asthma-Related Anxiety Scale (PASS), and the Physical Activity Parenting Practices - Short Form (PAPP). Results: Most patients had mild asthma (69.4%). Children with moderate to severe asthma had increased asthma-related anxiety (mean = 11.94 ± 6.1) compared with children with mild asthma (mean = 5.97 ± 6.39, p = 0.003). Parents of children with mild asthma reported behaviours allowing unsupervised physical activity outside more often when compared to parents of children with moderate or severe asthma. Physical activity facilitation parenting behaviour reduced the odds of a child's need for quick-reliever medication when symptomatic (OR = 0.376,95% CI = -1.885 to -0.072; p = 0.034); more coercive parenting increased the odds of a child's additional use of such medications (OR = 2.602; 95% CI = 0.005 to 1.908; p = 0.049). Parents of children in the highest quartile of trait anxiety showed less non-directive support (1.97 ± 1.01 vs. 2.89 ± 1.19, p = 0.031) and less autonomy support (3.14 ± 1.32 vs. 4.11 ± 1.23, p = 0.037) of physical activity in their children than those with less trait anxiety. Conclusion: Asthma-related anxiety was an important construct in this sample of children, associated with their disease severity as well as their parent's behaviours around the child's physical activities. Current research, conducted during the COVID-19 pandemic, recognised the tangible ways that parents support or avoid the asthmatic children's physical activity participation. Child anxiety and recognised parental physical activity behaviours are potentially important factors to assess and target for intervention.

The COVID-19 lockdown promotes changes in sleep habits in the Croatian general population.

AIM: To investigate the effects of the coronavirus disease 2019 (COVID-19) lockdown on sleep habits in the Croatian general population. METHODS: In this cross-sectional study, 1173 respondents from the general population (809 women) completed a self-report online questionnaire that gathered demographic data and data on sleep habits and mood changes before and during the COVID-19 lockdown. RESULTS: During the lockdown, bedtime (from 23:11±1:07 to 23:49±1:32 h, P<0.001) and waketime were delayed (from 6:51±1:09 to 7:49±1:40 h, P<0.001). Sleep latency increased from 10 (5-20) to 15 (10-30) minutes (P<0.001). Bedtime and waketime delays were more pronounced in women and respondents younger than 30. Compared with other age groups, respondents younger than 30 more frequently reported insomnia for the first time during the lockdown and had less frequent night-time awakenings (P<0.001), less common problems falling asleep (P<0.001), less frequently felt calm (P<0.001) and rested (P<0.001), but more frequently felt sadness (P<0.001) and fear (P=0.028). CONCLUSION: The effect of the lockdown on sleep needs to be better understood. Sleep hygiene education could serve a first-line lifestyle intervention for people in lockdown experiencing sleep disruption.

The construction of the Split Sleep Questionnaire on sleep habits during the COVID-19 pandemic in the general population.

AIM: To construct a single-format questionnaire on sleep habits and mood before and during the COVID-19 pandemic in the general population. METHODS: We constructed the Split Sleep Questionnaire (SSQ) after a literature search of sleep, mood, and lifestyle questionnaires, and after a group of sleep medicine experts proposed and assessed questionnaire items as relevant/irrelevant. The study was performed during 2021 in 326 respondents distributed equally in all age categories. Respondents filled out the SSQ, the Pittsburgh Sleep Quality Index (PSQI), and State Trait Anxiety Inventory (STAI), and kept a seven-day sleep diary. RESULTS: Cronbach alpha for Sleep Habits section was 0.819, and 0.89 for Mood section. Test-retest reliability ranged from 0.45 (P=0.036) for work-free day bedtime during the pandemic to 0.779 (P<0.001) for sleep latency before the pandemic. Workday and work-free day bedtime during the COVID-19 pandemic assessed with SSQ were comparable to the sleep diary assessment (P=0.632 and P=0.203, respectively), as was the workday waketime (P=0.139). Work-free day waketime was significantly later than assessed in sleep diary (8:19±1:52 vs 7:45±1:20; P<0.001). No difference in sleep latency was found between the SSQ and PSQI (P = 0.066). CONCLUSION: The SSQ provides a valid, reliable, and efficient screening tool for the assessment of sleep habits and associated factors in the general population during the COVID-19 pandemic.

The COVID-19 Lockdown and CPAP Adherence: The More Vulnerable Ones Less Likely to Improve Adherence?

PURPOSE: Due to the possible interplay of factors predisposing to severe COVID-19 outcomes and negative health consequences of poorly controlled OSA, adherence to continuous positive airway pressure (CPAP) therapy among OSA patients might be crucial during COVID-19 pandemics. Lockdown-related changes in CPAP adherence were investigated in CPAP users willing to participate in this study. Pre-lockdown adherence, age, gender, comorbidities and anxiety were analyzed as predictors of COVID-19 lockdown adherence. PATIENTS AND METHODS: A cross-sectional study performed at Split Sleep Medicine Center included 101 severe OSA patients (78.2% male). CPAP memory cards were assessed during 6 months of pre-lockdown and 40 days of lockdown (March/April 2020) period. A total of 81 patients in pre-lockdown met good CPAP adherence criteria (≥4 hours/night on 70% nights). RESULTS: CPAP adherence improved during COVID-19 lockdown in the total sample of severe OSA patients. The percentage of adherent nights and CPAP usage hours per night increased during lockdown in good pre-lockdown CPAP adherers (p=0.011 and p=0.001, respectively), women (p=0.003 and p=0.001, respectively) and respondents younger than 58 years (p=0.007 and p<0.001, respectively). Out of 20/101 poor pre-lockdown CPAP adherers, 9 have shifted to good lockdown adherence. When comorbidities, BMI and anxiety were taken into account, older and male respondents were recognized as less likely to improve CPAP usage hours during lockdown (R2=9.4%; p=0.032). CONCLUSION: The lockdown-related CPAP adherence improved in severe OSA patients, with a shift in almost half of poor pre-lockdown adherers towards good lockdown CPAP adherence. Women, younger and good pre-lockdown CPAP adherers were more adherent during lockdown. Despite being vulnerable groups for both OSA and COVID-19, no expected adherence improvements were observed in men and older patients.

The effect of COVID-19 lockdown on lifestyle and mood in Croatian general population: a cross-sectional study.

AIM: To investigate the effect of the coronavirus 2019 (COVID-19) lockdown on lifestyle behaviors and mood changes in the Croatian general population. METHODS: During ten days of the COVID-19 lockdown in Croatia, 3027 respondents (70.3% female) from the general population completed an online, self-report questionnaire. Demographic data and data on lifestyle habits and mood changes before and during the COVID-19 lockdown were collected. RESULTS: A total of 95.64% of respondents reported to follow most or all restrictions, with female sex (P<0.001) and higher education level (P<0.001) being associated with higher restriction compliance. Women smoked an increased number of cigarettes (P<0.001). The proportion of respondents of both sexes who did not drink or drank 7 drinks per week or more increased (P<0.001). Women also reported lower frequency (P=0.001) and duration of physical exercise (P<0.001). In total, 30.7% of respondents gained weight, with female sex (OR, 2.726) and higher BMI (OR, 1.116; both P<0.001) being associated with an increased likelihood of gaining weight. Both men and women felt more frequently afraid (P<0.001), discouraged (P<0.001), and sad (P<0.001). CONCLUSION: Public health authorities should promote the adoption of healthy lifestyles in order to reduce long-term negative effects of the lockdown.
