Abstract
Objective

To evaluate sleep characteristics of parents and their children during the COVID-19 pandemic and predictors for sleep disturbances.

Methods

Cross-sectional web-based study using an online survey made available for dyads of parents and their children during the 7th week of quarantine in southern Brazil. Parents' and adolescents’ sleep were characterized using the Pittsburgh Sleep Quality Index and the Epworth Sleepiness Scale. For children aged 0-3 years parents completed the Brief Infant Sleep Questionnaire, for those aged 4-12 years the Sleep Disturbance Scale for Children. Parents also informed, subjectively, their perception about sleep habits during social distancing. Multiple regression was run to predict sleep disturbances in adults using independent variables: sex, income, education, children age, and children with sleep disturbances.

Results

Data from 577 dyads showed sleep alterations in 69,8% of adults, in 58,6% of children aged 0-3 years, 33,9% in the 4-12 years range (with a predominance of disorders of initiating or maintaining sleep), and 56,6% in adolescents. Sex (female) and children with sleep disturbances were significant predictors of a sleep problem in parents (p < 0.005). Subjective perception revealed complaints related to emotional concerns such as anxiety and fear in adults and due to alterations in routine in children and adolescents.

Conclusion

The present study's data showed an increased rate of sleep problems among families during quarantine both measured by validated instruments and also based on personal perception.

Introduction

At the end of December 2019, a series of pneumonia cases with unknown etiology affected 41 patients in the city of Wuhan, China.1 Quickly, it was discovered that the cause was the contamination by a new type of coronavirus called COVID-19. Based on the rapid increase in the number of infections WHO declared the outbreak of COVID-19 as a pandemic.2

To reduce transmission, classical public health measures to contain the advance in the number of contaminations were applied, and to prevent the spread of the virus from person to person social isolation was adopted.3 Based on the increased number of cases and the rapid transmission among the population, the government adopted a ‘stay-at-home’ order, closing all schools, universities, and non-essential activities since March, 16th, 2020. This order forced several drastic lifestyle changes such as remote working and home-schooling. In addition, the imposed social distancing and a lack of social interaction caused by stay-at-home order, together with the separations of loved ones, loss of freedom of movement, uncertainty, and fear about the disease were associated with behavioral and psychological consequences.4

Prolonged home confinement affects physical and mental health with families being forced to promote sudden alterations in daily-life activities, together with reduced levels of physical activity, altered pattern of food consumption, and consequently weight gain.5 In addition, the uncertainty about the future, with financial and health concerns promotes a very stressful situation that could likely impact sleep habits. Sleep is an essentially biological process for life and health and plays an important role in the regulation of brain function, metabolism, immune system, hormonal secretion, and cardiovascular system.6

All of a sudden, children and adolescents were challenged by substantial lifestyle changes that include online lessons and altered routine habits. Also, home confinement reduced substantially social interaction and outdoor activities, resulting in increased screen time.7 Previous studies already showed that home confinement during the COVID-19 outbreak promoted altered sleep habits, resulting in sleep disturbances in both children and adolescents. An Italian survey with 4312 subjects showed that younger children had an increased prevalence of difficulty falling asleep and night awakenings.8 Also, another European survey showed acute worsening in the sleep of babies and children 0-6 years old.9 To date, a big Brazilian online survey was previously published with 45,161 adults and assessed sleep quality in the population, describing a 44.9% increase in sleep problems during the COVID-19 outbreak.10 Data regarding sleep quality in children and adolescents in Brazil are lacking. It is reasonable to hypothesize that the ‘stay-at-home’ order could impact the sleep quality of families living together in a regimen 24/7, without regular routines due to work or school duties. Chronic sleep disturbances might have an impact on public health, considering that individuals exposed to sleep disorders can have several changes in behavior and peripheral signaling systems.6

Considering that sleep quality is closely linked to overall health, it is important to investigate the impact of social distancing measures on the sleep characteristics of the population. Thus, this study aimed to investigate sleep characteristics of dyads (parents and their children) as well as predictors for poor sleep quality during social distancing caused by the COVID-19 pandemic.

Methods

This is a cross-sectional web-based study. Data were collected using an online survey (Qualtrics® online survey software (www.qualtrics.com) during the “stay-at-home” order. Participants were invited through social media (Instagram, Facebook, and Whatsapp advertisements) and via the internet, radio, and TV calls between the 27th of April, and the 30th of July 2020). The present study was approved by the institutional Ethical Committee and is registered on Plataforma Brasil under the number 30748320.5.0000.5336. Consent was obtained via a consent form found at the start of the online questionnaire and respondents were only able to proceed with the survey if they clicked on “I agree to participate in this study”. This survey was designed for parents and their children but the authors cannot completely rule out the possibility of an under-age to access the survey and take part without their parent's approval. Unfortunately, this is a common issue that applies in online, web-based surveys. However, the authors took great care to make sure that the survey did not include any question that would elicit a negative influence or represent any risk.

Parents were asked to provide sociodemographic data and directed to complete the “Pittsburgh Sleep Quality Index” and the “Epworth Sleepiness Scale”. The educational level and income were evaluated and ranked following Brazilian Statistics Institute, a public institution responsible for collect and publish all the geographical data in Brazil. Afterward, were asked to answer if, during home confinement caused by COVID-19, their sleep changed, with the following options: 1) Improved; 2) Worsened; 3) Not changed/Don't know. To qualitatively evaluate the participant's perception regarding the reason for such a change, the following open question was made: “If you have experienced any changes, describe in a short sentence what you believe is the reason”. Upon completing the first section, adults were asked whether or not they have kids living together and then directed to the appropriate instruments. For analysis, the authors have included only questionnaires with full answers completed.

For adults, the Brazilian version of the “Pittsburgh Sleep Quality Index (PSQI)”, was applied.11 A global score of equal or greater than five distinguishes poor and good sleepers. In addition, the Brazilian version of the “Epworth Sleepiness Scale”, a 6-item survey where the participants score, in a 0-3 Likert Scale the probability of nap or fall asleep in daily-life activities was also applied. From a total of 24 points, a score >10 indicates mild or excessive daytime sleepiness.12

For children aged 0 to 3 years and 11 months, parents were asked to respond to the “Brief Infant Sleep Questionnaire (BISQ),13 for children aged 4 to 12 years and 11 months, parents were asked to respond to the Brazilian version of the “Sleep Disturbance Scale for Children (SDSC)14 and for adolescents (under 18 years old) it was also used the PSQI. To calculate sleep disturbances rates, the authors used previously standardized cut-off scores for each of the previously mentioned instruments. For BISQ, the cut-off score was one (or more) of the following: more than 3 nocturnal awakenings, nocturnal wakefulness greater than 1h, and/or total sleep time lower than 9 hours.13 For SDSC scores were calculated as follow: Disorders of initiating and maintaining sleep (sum of items 1, 2, 3, 4, 5, 10, and 11, cut-off ≥ 17 points); Sleep breathing disorders (sum of items 13, 14, and 15, cut-off ≥ 7 points; Disorders of arousal (sum of items 17, 20 and 21, cut-off ≥ 6 points); Sleep-wake transition disorders (sum of items 6, 7, 8, 12, 18 and 19, cut-off ≥ 14 points); Excessive daytime sleepiness (sum of items 22, 23, 24, 25 and 26, cut-off ≥ 13 points); Sleep hyperhidrosis (sum of items 9 and 16, cut-off ≥ 7 points). A cut-off score ≥ 52 points were used regarding the total score. For adolescents, the PSQI cut-off score ≥ 5 points were used.11

Tag clouds are a text-based visual depiction of words used to display the relative word frequency, popularity or importance by font size and tag clouds can also serve as a summary of the content. To create the tag clouds, data derived from the open question “If you have experienced any changes, describe in a short sentence what you believe is the reason” was organized and the most cited terms were sorted and selected for visual depiction.

Considering that Brazil has continental proportions and public policies to contain COVID-19 spread were heterogeneous, for this study the authors have included only responders that live in southern Brazil, at the Rio Grande do Sul state, during the period between April 27th and May 6th (7th week of quarantine) because there was a homogeneous control of social distancing policies established based on colored flags and all the region was under red flag alert system.

Data analysis

The primary objective of this study was to analyze the sleep quality of both parents and their children during COVID-19 lockdown. The authors further choose to analyze possible predictors of sleep disturbances of parents such as sex, income, education, children's age, and children with sleep disturbances. Finally, exploratory analysis of sleep scores between subjects that have children compared to subjects with no children.

Data were analyzed using the software SPSS, version 20.0. Mean value, standard deviation, and frequency was calculated, as well as the difference between groups, using t test and chi-square test. A student's t test was used to compared PSQI global between parents with kids and parents with no kids. In addition, the authors used a one-way ANOVA to analyze the differences between groups in the PSQI sub scores and global scores using the overall subjective perception of sleep quality (improved, worsened, and no change/don't know as an independent variable. The authors also analyzed PSQI sub scores and global scores using the child's age as an independent variable (0-3 years old, 4-12 years old and adolescents). For all one-way ANOVA, a Bonferroni multiple comparisons were used to detect between groups' differences.

A multiple regression model was adopted with PSQI scores as a dependent variable and the following independent variables (predictor): sex, income, education, children's age, and children with sleep disturbances. All analyses were two-tailed and the significance level was set at p < 0.05.

This sample size was calculated using the Brazilian population (22 million) with an error of 2% and significance of 5%, leading to a sample size of 2401 respondents. From there, the authors selected a sub-sample of respondents that reported having children and compared it to a random sample of respondents that reported not having children.

ResultsSleep characteristics among parents and their children

A total of 2484 adults completed the online survey to investigate sleep quality in the Brazilian population during the COVID-19 pandemic (unpublished data). From these, 577 participants completed the survey during the 7th week of quarantine, living in the Rio Grande do Sul state and reported having children under 18 years old (173 from 0-3 years; 254 aged 4-12 years and 150 aged 13-17 years old). Sex distribution showed an increased percentage of women (81,7%) as respondents. The distribution of the adult sample regarding income and education level is presented in Table 1. The authors found a significant amount of respondents with poor sleep quality with education level “with some college, no degree” (X² = 14,484, p < 0,001) and “advanced degree” (X² = 15,382, p < 0.001).

Table 2 presents the general sleep characteristics of the sample. In parents, 405 (70,1%) had PSQI scores that indicate poor sleep quality. Among PSQI domains, 78,6% had poor sleep latency and 31,5% had poor sleep efficiency. Poor sleep duration was observed in 42,9%. For children aged 0-3 years, 126 (58,6%) have abnormal BISQ scores and among children, 4-12 years old, 99 (33,9%) children have scores that indicate disorders of initiating and maintaining sleep, and 54 (18,5%) children presented sleep-wake transition disorders. For adolescents, 85 (56,6%) had poor sleep quality (PSQI global score ≥ 5).

Sleep quality auto perception and PSQI scores in parents

A student t-test showed that PSQI scores between parents and adults without kids did not differ significantly. It is important to note that both groups score higher than 5, which indicates poor sleep quality (Fig. 1A).

To analyze the agreement between subjective perception of overall sleep quality during the COVID-19 pandemic and the scores of PSQI, the authors conducted a one-way ANOVA that showed a statistically significant difference in all PSQI subscores between parents who perceived an improvement in sleep quality when compared to parents who perceive a worsening in sleep quality during home confinement (Fig. 1B).

Later, the authors also compared the PSQI score of parents based on the children's age, to investigate if parents who have babies, younger children, or adolescents present differences across PSQI sub scores. The authors found no statistically significant differences between groups, suggesting that the child's age does not alter the parents’ PSQI sub-scores (Fig. 1C).

Predictors of sleep disturbances during home confinement

Another goal of this study was to test which variables could be associated with the sleep disturbances of parents during home confinement. Thus, a multiple regression was run to predict sleep disturbances in adults from sex, income, education, children's age, and children with sleep disturbances. A significant regression equation was found F(5,576) = 2,681, p < 0.05. In the present study's model, sex (female) and children with sleep disturbances were significant predictors of a sleep problem in parents (Table 3).

Qualitative aspects of sleep during home confinement

Finally, to analyze the qualitative data, the authors selected the 10 most cited terms in the opened questions to be visually depicted in Supplementary Material - Fig. S1. Among adults, the word “Anxiety” appeared 169 times, followed by “Routine changes” (76), “Worry” (51), “Fear” (40), “Lack of daily activities” (36), “Dreams” (35), “Pandemic” (21), “Sleep more hours” (20), “Stress” (19) and “Tiredness” (18). Among children aged 0-3 years, the 10-most cited terms that appeared were “Sleep Later” (52), “Routine Changes” (34), “Accumulated energy” (11), “Agitation” (11), “Anxiety” (10), “Missing school” (9), “No nap during the day” (7) and “altered number of feeding” (7). For children 4-12 years old, the terms were “Sleep later” (52), “Routine changes” (38), “Fear” (21), “Missing school” (13), “Anxiety” (11), “Sleeping with parents” (11), “Accumulated Energy” (9), “Using more electronic device” (8), “Missing friends” (7) and “Difficulty to start sleep” (7). For adolescents, the 10-most cited terms were “Sleep Later” (23), “Anxiety” (17), “Routine changes” (13), “Using more electronic device” (13), “Missing School” (10), “Online classes” (6), “Lack of physical activity” (4), “Nightmares” (4) and “Accumulated energy” (2) (Fig. 2).

Discussion

The study showed that almost 70% of the present study's adult sample have poor sleep quality, with higher sleep latency (amount of time it takes to fall asleep) and poor efficiency (amount of time a person sleeps in relation to the amount of time spent in bed). For children aged 4-12 years the main problem was initiating and/or maintaining sleep, and for the 0-3 years group increased nocturnal awakenings. The authors have also found that sex and having a child with sleep disturbances significantly predicted parents' sleep problems.

Different from previous studies that addressed sleep in adult samples of health workers, much more exposed to stressful situations, or adults with other comorbidities such as mental disorders or obstructive sleep apnea,15–17 this study focused on families from a general population at a time-limited period of quarantine. Further, no previous studies have associated parents and their children's sleep habits during the lockdown. Although the present study's data do not allow a direct cause-effect association of stay-at-home order and an increased rate of poor sleep quality in adults, the authors can hypothesize that the stressful context of pandemic confinement is leading to alterations in sleep quality. It was already been shown that other stressful contexts such as work overload and occupational stress were positively associated with the frequency of poor sleep quality. In addition, a recent report by Coiro et al (2021) found higher rates of depression and anxiety, as well as poor sleep quality in the United States and Israel respondents.18

The percentage of altered sleep observed in the adult population analyzed in this study was superior to what was reported in similar ones developed in Greece (sleep problems were detected in 37.6%) and the USA (25%).19,20 The Italian study showed an increase in sleep disorders from 40.5% previous to lockdown to 52.4% in the second week of isolation, but the population studied had also a high incidence of behavioral and mood disorders.21 However, those studies analyzed data collected around the second week of lockdown. The present study's increased rates might be explained by the timing of the questionnaire, during the 7th week of quarantine, and by the feeling of elongation of time in a longer period of isolation.

Interestingly, the most cited word among parents in the open question was “Anxiety”. The relationship between anxiety and sleep problems is known for a long time.15 It is hard to distinguish if people are anxious and therefore, they have trouble sleeping or sleeping problems that make people anxious. Nevertheless, anxiety and sleep are strictly related and affect which other in a two-way manner. Recent studies during the COVID 19 pandemic showed this association in different sectors and populations.15,16,20-23 In addition, it is important to note that a quarter of this study's sample reported the use of medication to sleep once or twice a week (PSQI item 7) which could be related to increased latency to sleep and anxiety.

Data regarding children also showed the impact of isolation on sleep. Approximately one-third of the 4-12 years group had scores that indicate potential disorders of initiating and maintaining sleep. In addition, routine changes were frequently reported by participants as a factor that could contribute to altered sleep. According to previous work from the present study's group, a population-based study that evaluated sleep in Brazilian children and adolescents,24 the overall prevalence of sleep disturbance was 25.5%, using the same instruments according to age groups (0-3 years: BISQ, 4-12 SDSC and PSQI for adolescents). Also, the prevalence of sleep problems among children aged 0-3 years (58.6%) found in this study was a striking difference, when compared to the previous (20%) with a very similar methodological approach (online-based survey with same instruments). Overall, in a very narrow window of time, the authors found an increase in the prevalence of sleep disturbances in children, and this might be due to the changing of habits during quarantine. Although there is not yet much data available regarding the effects of the COVID quarantine on sleep in children, in a national survey developed in Canada, 1/3 of the families were not following the recommendations for sleep hygiene and a significant decrease in physical activity was also observed.25 These findings might have important public health implications as in a recent study published by Morales-Muñoz and collaborators,26 it was observed that some behavioral sleep problems early in childhood are associated with psychosis and borderline personality disorder in adolescence. Further, depression at 10 years of age was associated with frequent night awakenings at 18 months of age and irregular sleep routines at 5.8 years of age.27 Additionally, another recent paper that investigated psychological symptoms, non-suicidal self-injury, and suicidal (ideation, plans, and attempts) among a cohort of Chinese children and adolescents before the outbreak of COVID and 3 months later, after school reopening, demonstrated a significant increase in the rates of mental health problems.25

Although the authors have not longitudinally followed this cohort, a limitation of this study, the present study's data showed an impressive rate of poor sleep quality, during a period with a homogeneous regulation of social restrictions. Another limitation of this study is a high prevalence of higher educated respondents, which could impair the generalization of these findings to lower educated populations, considering that the COVID-19 pandemic could have a different impact on people from different socioeconomic statuses. In addition, the authors configure the survey to allow adults to respond regarding only one child and the authors cannot control or ensure what was the criteria for parents to choose from which kids they were responding (the younger, the worst sleeper, etc).

In conclusion, the authors have observed a great overall perception of worsening in sleep quality during stay-at-home orders either in adults and children in southern Brazil. The more frequent complaints about irregular sleep in parents were emotional concerns such as anxiety and fear and alterations in routine and sleep habits for children.
