Comparing web-based versus face-to-face and paper-and-pencil questionnaire data collected through two Belgian health surveys

The Impact of Removing the 10-Minute Bout Requirement and of Different Survey Administration Methods on National Physical Activity Estimates in Austria

BACKGROUND

Monitoring survey methods, as well as movement recommendations, evolves over time. These changes can make trend observations over time difficult. The aim of this study was to examine the differences between 2 computer-assisted survey administration methods and the effect of the omission of the 10-minute minimum bout requirement in physical activity (PA) questions on PA outcomes.

METHODS

We used data from the second Austrian PA Surveillance System for 2998 adults (18-64 y), applying computer-assisted personal interviewing and computer-assisted web interviewing. Within the computer-assisted web interviewing sample only, we added PA questions without the 10-minute requirement. Quantile and logistic regressions were applied.

RESULTS

Between computer-assisted web interviewing and computer-assisted personal interviewing, within the computer-assisted personal interviewing sample, we found lower PA estimates in the leisure domain and work and household domain, but not in the travel domain, and no significant difference in the proportion of people meeting the PA recommendations. In all 3 PA domains, the median minutes did not differ when assessed with or without the 10-minute requirement. However, the percentage participation in the travel domain and work and household domain performing >0 minutes per week PA was higher when there was no 10-minute requirement. The proportion of people meeting the Austrian aerobic recommendation for adults when computed with or without the 10-minute requirement did not differ.

CONCLUSION

Our findings suggest that the omission of the 10-minute requirement does not seem to result in marked differences in PA estimates or the proportion of adults meeting the recommendations.

Psychometric properties of the Swedish version of the international outcome inventory - alternative interventions (IOI-AI) - ear surgery (IOI-AIop)

OBJECTIVE

The aims of this study were to adapt the Swedish version of the International Outcome Inventory for Hearing Aids (IOI-HA) to the International Outcome Inventory for Alternative Interventions (IOI-AI) in the context of ear surgery (IOI-AIop) and to test the psychometric properties.

DESIGN

The validated Swedish questionnaire IOI-HA was adapted to the IOI-AIop by omitting the question about hearing aid use and changing the term "hearing aid" to "surgery" in the remaining items. The validity, component structure and reliability of the IOI-AIop were assessed.

STUDY SAMPLE

Subjects diagnosed with otosclerosis and undergoing stapedotomy were included in the study (n = 162).

RESULTS

High mean scores were noted for all items. Ceiling effects were noted, most pronounced for the satisfaction item. Principal component analysis (PCA) yielded a two-component structure explaining 77.5% of the variance. The test-retest reliability measured by intra class correlation coefficient was >0.9, and the internal consistency coefficient measured by Cronbach's alfa was >0.8.

CONCLUSION

The IOI-AIop showed good psychometric properties. However, ceiling effects were observed. The two-component solution was in line with previous factor analyses of the IOI-HA and the IOI-AI. The comprehensive IOI-AIop is recommended as a useful tool to evaluate patient perspectives after ear surgery.

Health estimate differences between six independent web surveys: different web surveys, different results?

Most general population web surveys are based on online panels maintained by commercial survey agencies. Many of these panels are based on non-probability samples. However, survey agencies differ in their panel selection and management strategies. Little is known if these different strategies cause differences in survey estimates. This paper presents the results of a systematic study designed to analyze the differences in web survey results between agencies. Six different survey agencies were commissioned with the same web survey using an identical standardized questionnaire covering factual health items. Five surveys were fielded at the same time. A calibration approach was used to control the effect of demographics on the outcome. Overall, the results show differences between probability and non-probability surveys in health estimates, which were reduced but not eliminated by weighting. Furthermore, the differences between non-probability surveys before and after weighting are larger than expected between random samples from the same population.

Health Care Personnel's Perspectives on Quality of Palliative Care During the COVID-19 Pandemic - A Cross-Sectional Study

Purpose

The provision of high-quality palliative care is challenging, especially during a pandemic like COVID-19. The latter entailed major consequences for health care systems and health care personnel (HCP) in both specialist and community health care services, in Norway and worldwide. The aim of this study was to explore how the HCP perceived the quality of palliative care in nursing homes, medical care units, and intensive care units during the COVID-19 pandemic.

Methods

This study had a cross-sectional design. A total of 290 HCP from Norway participated in the study (RR = 25.8%) between October and December 2021. The questionnaire comprised items concerning respondents' demographics and quality of care, the latter measured by the short form of the Quality from the Patient's Perspective-Palliative Care instrument, adapted for HCP. The STROBE checklist was used.

Results

This study shows that the HCP scored subjective importance as higher in all dimensions, items and single items than their perception of the actual care received. This could indicate a need for improvement in all areas. Information about medication, opportunity to participate in decisions about medical and nursing care and continuity regarding receiving help from the same physician and nurse are examples of areas for improvement.

Conclusion

Study results indicate that HCP from nursing homes, medical care units, and intensive care units perceived that quality of palliative care provided was not in line with what they perceived to be important for the patient. This indicate that it was challenging to provide high-quality palliative care during the COVID-19 pandemic.

Sun-protective behaviors and sunburn among US adults

Individuals can reduce the risk of developing skin cancer by minimizing ultraviolet sunlight exposure, though recent trends in sun-protective behaviors remain to be investigated. To evaluate sun-protective behaviors and sunburn among US adults. We analyzed data from the 2010, 2015, and 2020 National Health Interview Survey (NHIS), an annual, cross-sectional survey conducted by the US Census Bureau. Multivariable regression models were stratified by demographic variables and constructed to evaluate sun-protective behaviors and sunburn avoidance across time. From 2010 through 2020, US adults had significantly increased prevalence of seeking shade (p value, 0.003), wearing wide-brimmed hats (< 0.001), wearing long-sleeved shirts (< 0.001), using sunscreen (< 0.001), and avoiding sunburns (< 0.001) and significantly decreased prevalence of sun avoidance (< 0.001). Disparities in sun-protective behaviors also exist among different sexes, ages, education levels, and those reporting higher sun sensitivity. This cross-sectional study found that by 2020, US adults had an increased prevalence of wearing sun-protective clothing and sunscreen use, though decreased prevalence of sun avoidance. Although certain sun-protective behaviors have become more prevalent, the incidence of skin cancer continues to rise. Efforts to understand drivers of sun-protective behaviors and targeted intervention efforts are needed.

A Web-Based Instrument for Infantile Atopic Dermatitis Identification (Electronic Version of the Modified Child Eczema Questionnaire): Development and Implementation

BACKGROUND

Atopic dermatitis (AD) is a chronic inflammatory cutaneous disease that affects 30.48% of young children; thus, there is a need for epidemiological studies in community settings. Web-based questionnaires (WBQs) are more convenient, time-saving, and efficient than traditional surveys, but the reliability of identifying AD through WBQs and whether AD can be identified without the attendance of doctors, especially in community or similar settings, remains unknown.

OBJECTIVE

This study aimed to develop and validate a web-based instrument for infantile AD identification (electronic version of the modified Child Eczema Questionnaire [eCEQ]) and to clarify the possibility of conducting WBQs to identify infantile AD without the attendance of doctors in a community-representative population.

METHODS

This study was divided into 2 phases. Phase 1 investigated 205 children younger than 2 years to develop and validate the eCEQ by comparison with the diagnoses of dermatologists. Phase 2 recruited 1375 children younger than 2 years to implement the eCEQ and verify the obtained prevalence by comparison with the previously published prevalence.

RESULTS

In phase 1, a total of 195 questionnaires were analyzed from children with a median age of 8.8 (IQR 4.5-15.0) months. The identification values of the eCEQ according to the appropriate rules were acceptable (logic rule: sensitivity 89.2%, specificity 91.5%, positive predictive value 97.1%, and negative predictive value 72.9%; statistic rule: sensitivity 90.5%, specificity 89.4%, positive predictive value 96.4%, and negative predictive value 75%). In phase 2, a total of 837 questionnaires were analyzed from children with a median age of 8.4 (IQR 5.2-14.6) months. The prevalence of infantile AD obtained by the eCEQ (logic rule) was 31.9% (267/837), which was close to the published prevalence (30.48%). Based on the results of phase 2, only 20.2% (54/267) of the participants identified by the eCEQ had previously received a diagnosis from doctors. Additionally, among the participants who were not diagnosed by doctors but were identified by the eCEQ, only 6.1% (13/213) were actually aware of the possible presence of AD.

CONCLUSIONS

Infantile AD can be identified without the attendance of doctors by using the eCEQ, which can be easily applied to community-based epidemiological studies and provide acceptable identification reliability. In addition, the eCEQ can also be applied to the field of public health to improve the health awareness of the general population.

The Current Knowledge, Attitudes, and Practices of the Neglected Methodology of Web-Based Questionnaires Among Chinese Health Workers: Web-Based Questionnaire Study

BACKGROUND

Web-based questionnaire (WBQ) surveys are popular, but the quality of reporting WBQ survey research is uneven and unsatisfactory worldwide. Education and training on WBQ methodology may be necessary. However, the current knowledge, attitudes, and practices (KAP) of its methodology remain unknown.

OBJECTIVE

We investigated the KAP of WBQ methodology among Chinese health workers for the first time to clarify the possible reasons for the unsatisfactory reporting quality of WBQ survey research from China's experience, aiming to provide a basis for improvement.

METHODS

We developed a structured WBQ based on the current recommendations and knowledge and investigated 458 health workers from June 7 to July 6, 2022. A total of 381 valid questionnaires were analyzed after data processing. We defined 50% and 75% as "qualified" and "satisfactory" in knowledge and practice topics to describe the results and analyzed the basic characteristics of the participants who had difficulties in conducting WBQ survey research.

RESULTS

A total of 215 (56.4%) participants had used WBQs for investigation, mostly more than 2 times (88.3%), but only 95 (44.2%) of them had ever received methodological training. A total of 134 (62.3%) users believed that WBQs were practical, but 126 (58.6%) had doubts about the reliability of the results. Most of the knowledge and practice topics did not reach a satisfactory level, and some even did not reach a qualified level. A total of 95 (44.2%)-136 (63.3%) of the users had reported difficulties in conducting WBQ survey research, and different participants could have different difficulties according to their characteristics. In addition, 191 (88.8%) users believed training was necessary.

CONCLUSIONS

We found that Chinese health workers seriously underestimated and neglected the importance of the WBQ methodology, which may be an important reason for the reduced reporting quality of WBQ survey research. Medical educators need to strengthen methodological training on WBQs, which may help to improve the quality of WBQ survey research.

Validation of online version of asthma control questionnaire in pediatric patients

Introduction: The Asthma Control Questionnaire (ACQ) is a seven-item questionnaire assessing symptoms that asthma clinicians consider to be most important for evaluating the adequacy of asthma control. An online version of the ACQ may be able to indicate whether a visit to the physician is warranted to modify therapy to achieve better control of their asthma, ultimately reducing the number of unnecessary visits, particularly during the pandemic. The aim of our study is to compare the paper and online ACQ to validate the online version for use in real-life settings.Methods: Our study included 28 patients who completed both paper and the online ACQ on the same day when they came home. The online version of the questionnaire was prepared to look similar to the paper form, with the same sentences and answers.Results: The correlation between paper and online ACQ questionnaires was very high (r = 0.935; p < 0.001). When comparing each individual item, correlation coefficients ranged from 0.672 to 0.935. The lowest correlation is obtained in activity limitations, while the next one is 0.767, others higher than 0.8. The online form gave small and insignificantly higher scores compared to paper form with mean difference between -0.07 and 0.21. Mean difference of 0.01 (p = 0.986) between paper ACQ and online ACQ is obtained.Conclusion: The online version of the ACQ can be used for asthma control monitoring in pediatric patients in order to minimize unnecessary social contacts as well as hospital patient load, but retain adequate surveillance of disease symptoms by their physician.

The HLS19-COM-P, a New Instrument for Measuring Communicative Health Literacy in Interaction with Physicians: Development and Validation in Nine European Countries

BACKGROUND

Sufficient communicative health literacy (COM-HL) is important for patients actively participating in dialogue with physicians, expressing their needs and desires for treatment, and asking clarifying questions. There is a lack of instruments combining communication and HL proficiency. Hence, the aim was to establish an instrument with sufficient psychometric properties for measuring COM-HL.

METHODS

The HLS₁₉-COM-P instrument was developed based on a conceptual framework integrating HL with central communicative tasks. Data were collected using different data collection modes in nine countries from December 2019 to January 2021 (n = 18,674). Psychometric properties were assessed using Rasch analysis and confirmatory factor analysis. Cronbach's alpha and Person separation index were considered for reliability.

RESULTS

The 11-item version (HLS₁₉-COM-P-Q11) and its short version of six items (HLS₁₉-COM-P-Q6) fit sufficiently the unidimensional partial credit Rasch model, obtained acceptable goodness-of-fit indices and high reliability. Two items tend to under-discriminate. Few items displayed differential item functioning (DIF) across person factors, and there was no consistent pattern in DIF across countries. All items had ordered response categories.

CONCLUSIONS

The HLS₁₉-COM-P instrument was well accepted in nine countries, in different data collection modes, and could be used to measure COM-HL.

Assessing Telemedicine Efficiency in Follow-up Care With Video Consultations for Patients in Orthopedic and Trauma Surgery in Germany: Randomized Controlled Trial

Background

Telemedicine can help mitigate important health care challenges, such as demographic changes and the current COVID-19 pandemic, in high-income countries such as Germany. It gives physicians and patients the opportunity to interact via video consultations, regardless of their location, thus offering cost and time savings for both sides.

Objective

We aimed to investigate whether telemedicine can be implemented efficiently in the follow-up care for patients in orthopedic and trauma surgery, with respect to patient satisfaction, physician satisfaction, and quality of care.

Methods

We conducted a prospective randomized controlled trial in a German university hospital and enrolled 60 patients with different knee and shoulder conditions. For follow-up appointments, patients received either an in-person consultation in the clinic (control group) or a video consultation with their physician (telemedicine group). Patients’ and physicians’ subsequent evaluations of these follow-up appointments were collected and assessed using separate questionnaires.

Results

On the basis of data from 52 consultations after 8 withdrawals, it was found that patients were slightly more satisfied with video consultations (mean 1.58, SD 0.643) than with in-clinic consultations (mean 1.64, SD 0.569), although the difference was not statistically significant (P=.69). After excluding video consultations marred by technical problems, no significant difference was found in physician satisfaction between the groups (mean 1.47, SD 0.516 vs mean 1.32, SD 0.557; P=.31). Further analysis indicated that telemedicine can be applied to broader groups of patients and that patients who have prior experience with telemedicine are more willing to use telemedicine for follow-up care.

Conclusions

Telemedicine can be an alternative and efficient form of follow-up care for patients in orthopedic and trauma surgery in Germany, and it has no significant disadvantages compared with in-person consultations in the clinic.

Anxiety and Depression in Belgium during the First 15 Months of the COVID-19 Pandemic: A Longitudinal Study

The COVID-19 pandemic and policy measures enacted to contain the spread of the coronavirus have had nationwide psychological effects. This study aimed to assess the impact of the first 15 months of the COVID-19 pandemic on the level of anxiety (GAD-7 scale) and depression (PHQ-9 scale) of the Belgian adult population. A longitudinal study was conducted from April 2020 to June 2021, with 1838 respondents participating in 6 online surveys. Linear mixed models were used to model the associations between the predictor variables and the mental health outcomes. Results showed that the prevalence of symptoms of anxiety and depression was higher in times of stricter policy measures. Furthermore, after the initial stress from the outbreak, coping and adjustment were observed in participants, as symptoms of anxiety and depression decreased during times of lower policy restrictions to almost the same level as in pre-COVID times (2018). Though time trends were similar for all population subgroups, higher levels of both anxiety and depression were generally found among women, young people, people with poor social support, extraverts, people having pre-existing psychological problems, and people who were infected/exposed to the COVID-19 virus. Therefore, investment in mental health treatment programs and supports, especially for those risk groups, is crucial.

Use of online and paper-and-pencil questionnaires to assess the distribution of orthorexia nervosa, muscle dysmorphia and eating disorders among university students: can different approaches lead to different results?

PURPOSE

Administration of questionnaires to assess the diffusion of disordered eating behaviours via the web is becoming common today. The aim of this study is to assess whether two different approaches of administering a test to assess traits of eating disorders (EDs), orthorexia nervosa (ON) and muscle dysmorphia (MD) by email recruitment and online completion (web-based survey-WBS) and by in person recruitment and paper-and-pencil completion (paper-based survey-PBS), gives different results.

METHODS

During 2 consecutive academic years, a self-reported questionnaire consisting of questions about personal characteristics and three tests for the evaluation of ON (ORTO-15), MD (MDDI-ITA), and EDs (EAT-26) were administered to two groups of undergraduates, respectively, as a WBS and a PBS.

RESULTS

The WBS response rate was 6.7% (N = 137), and the PBS response rate was 86.5% (N = 372). The WBS group showed a statistically significant higher prevalence of students with eating disordered behaviours (21.2% vs 5.4%) and registered a higher mean score on the EAT-26 test (13.5 ± 11.1 vs 6.0 ± 8.0); no differences between the two groups emerged for ON and MD prevalence and test scores. Moreover, in the WBS group, the number of students with one or more tests with test scores above the cut-off values was significantly higher (46.0% vs 32.3%).

CONCLUSION

The choice of the approach to administer a questionnaire to assess the diffusion of EDs and related issues must take into account all the factors that can result in selection bias and that can affect the reliability of the results.

Domestic violence during the COVID-19 confinement: do victims feel more socially isolated?

BACKGROUND

Since March 13th 2020, confinement measures have been introduced in Belgium to curb the spread of the coronavirus (COVID-19). These measures also have an impact on people's daily life (closure of school/businesses, teleworking, recommendation to stay at home). This can cause stress on social, economic and psychological levels and thereby can trigger domestic violence. Besides, confinement also fosters social isolation, which can complicate help seeking behaviour. The aim of this study is to determine the prevalence of domestic violence during the coronavirus crisis and to assess whether there is an association between domestic violence and social isolation.

METHODS

Several online COVID-19 Health Surveys were organised among Belgian residents aged 18+ via snowball sampling. This study is based on the second (April 2020) and the sixth survey (March 2021). After excluding 1-person households and missing data, the sample size was respectively 25,251 and 12,589. Weighted prevalence of domestic violence was evaluated for the two surveys. The association (OR; 95% CI; p-value) between domestic violence and subjective social isolation was assessed with logistic regression stratified by survey and adjusted for covariates.

RESULTS

In April 2020, 4.0% of the adult population reported being a victim of domestic violence (1.2% in the Health Interview Survey 2018); in March 2021, this was 6.2%. In April 2020, victims of domestic violence had higher odds of being unsatisfied with their social contacts (OR = 1.25; 95% CI: 1.08-1.44; p < .05), weak social support (OR = 2.26; 95% CI: 1.97-2.58; p < .0001) and having less confidence in health care services (OR = 1.38; 95% CI: 1.13-1.71; p < .05). In March 2021, victims had higher odds of being unsatisfied with their social contacts (OR = 1.30; 95% CI: 1.08-1.56; p < .05) and weak social support (OR = 2.41; 95% CI: 2.04-2.84; p < .0001), and social (OR = 2.64; 95% CI: 2.23-3.13; p < .0001) and emotional loneliness (OR = 2.22; 95% CI: 1.80-2.73; p < .0001).

CONCLUSIONS

More people have reported domestic violence since the start of the coronavirus crisis than did in 2018. An association between domestic violence and social isolation was determined. Although confinement is needed to counteract the virus, it can put people in a dangerous situation since they do not get the help they need. Therefore, adequate support is essential.

COVID-19 and people who use drugs: Impact of the pandemic on general anxiety and depressive disorders among adults in Belgium

BACKGROUND

During previous pandemics people who use drugs (PWUD) were categorized among the most vulnerable. In the current study, firstly, we wanted to evaluate the impact of the COVID-19 crisis on the prevalence of anxiety and depressive disorders among PWUD. Furthermore, we wanted to compare the prevalence of these disorders with that of members from the general population who did not use drugs.

METHODS

We used a matched cohort design based on two separate repeated cross-sectional online surveys (April and November 2020) among PWUD and the general population. Results of GAD-7 and PHQ-9 were used as outcome variables. We calculated absolute and relative risks for matched pairs for both affective disorders, and logistic regression to compare affective disorders over both waves for PWUD.

RESULTS

In April, the prevalence of affective disorders was similar for PWUD and the general population. In November, the risks for anxiety disorders increased with 64% for PWUD compared to non-PWUD (RR = 1.64, 95%CI 1.42-1.88), whereas the risks for depressive disorders more than doubled (RR = 2.29, 95%CI 1.97-2.67). Having a job and being male were protective factors for PWUD for both anxiety and depressive disorders.

LIMITATIONS

As this study used self-reported data, GAD-7 and PHQ-9 give an indication of the presence of anxiety and depression which might differ from a clinician's judgement.

CONCLUSIONS

PWUD might be disproportionally affected by COVID-19. Health care providers should be attentive to substance use as an indicator for increased risk of mental health problems.

Comparison of the Differences Between Web-Based and Traditional Questionnaire Surveys in Pediatrics: Comparative Survey Study

BACKGROUND

A web-based survey is a novel method for data capture. Some studies have applied web-based surveys in pediatrics, but few of them have reported data on the differences between web-based and traditional questionnaire surveys.

OBJECTIVE

The objective of our study was to evaluate the internal consistency of a web-based survey and compare it with a traditional questionnaire survey in pediatrics.

METHODS

A convenience sample of caregivers was invited to participate in the survey on feeding patterns and their children's eating behaviors if their children were aged 2 to 7 years. A web-based survey and a traditional questionnaire survey were carried out between October 2018 and July 2019. A total of 1085 caregivers were involved in this study, and they were divided into the following three groups based on methods and sources: (1) web-based survey from a web source, (2) web-based survey from a hospital source, and (3) traditional questionnaire survey from a hospital source. The data were then compared and analyzed.

RESULTS

A total of 735 caregivers participated in the web-based survey and 350 caregivers participated in the traditional questionnaire survey, and 816 cases were then included in the analyses after data processing. The effective rate of the web-based survey was 70.1% (515/735), and the completeness rate of the traditional questionnaire survey was 86.0% (301/350). There were no significant differences between web-based surveys from different sources. However, demographic characteristics were significantly different between the web-based and traditional questionnaire surveys, mainly in terms of age and caregivers (χ²₄=16.509, P=.002 and χ²₄=111.464, P<.001, respectively). Caregivers of children aged 2 to 3 years and grandparents were more likely to respond to the web-based survey. Age-specific stratified analysis showed that the score of "monitoring" and the reporting rate of "poor appetite" in children aged 2 to 3 years were significantly higher in the web-based survey compared to the traditional questionnaire survey after adjusting for demographic characteristics.

CONCLUSIONS

A web-based survey could be a feasible tool in pediatric studies. However, differences in demographic characteristics and their possible impacts on the results should be considered in the analyses.

Short-term impact of the COVID-19 confinement measures on health behaviours and weight gain among adults in Belgium

BACKGROUND

In Belgium, confinement measures were introduced on the 13th of March 2020 to curb the spread of the coronavirus disease (COVID-19). These measures may affect health behaviours of the population such as eating habits, physical activity and alcohol consumption, which in turn can lead to weight gain resulting in overweight and obesity, increasing the risk of several chronic diseases, but also of severe COVID-19. The purpose of this study is to assess the impact of confinement measures on health behaviours and their associations with weight gain.

METHODS

Data were derived from the second national COVID-19 health survey. Data were collected between the 16th and the 23rd of April 2020. The recruitment of participants was based on snowball sampling via Sciensano's website, invitations via e-mail and social media. The study sample includes participants aged 18 years and over with no missing data on the variables of interest (n = 28,029). The association between self-reported weight gain and health behaviour changes, adjusted for gender, age group and household composition was assessed through OR's (95% CI) calculated with logistic regression models, using post-stratification weights.

RESULTS

Overall, 28.6% reported weight gain after 6 weeks of confinement. Higher odds of weight gain were observed among participants who increased or decreased their consumption of sugar-sweetened beverages (OR = 1.39 (1.15-1.68) and 1.29 (1.04-1.60), respectively), among those who increased their consumption of sweet or salty snacks (OR = 3.65 (3.27-4.07)), among those who became less physically active (OR = 1.91 (1.71-2.13)), and among those who increased their alcohol consumption (OR = 1.86 (1.66-2.08)).

CONCLUSIONS

The most important correlates of weight gain during confinement were an increased consumption of sweet or salty snacks and being less physically active. These findings confirm the impact of diet and exercise on short term weight gain and plead to take more action, in supporting people to achieve healthier behaviours in order to tackle overweight and obesity, especially during the COVID-19 pandemic.

[The effects of quarantine for SARS-CoV-2 on sleep: An online survey]

Objectif

Déterminer l’évolution du sommeil chez les Français pendant le confinement motivé par la pandémie du SARS-CoV-2 et définir les facteurs comportementaux associés à un sommeil détérioré.

Méthodologie

Une enquête en ligne via les réseaux sociaux pendant la période de confinement. Les questions ont ciblé les conditions de confinement, les comportements relatifs au sommeil et les éléments de l’environnement potentiellement perturbateurs du sommeil (exposition à la lumière et activités sportives).

Résultats

Au total, 1777 participants ont été inclus dont 77 % femmes, 72 % âgés de 25–54 ans. Les conditions de confinement les plus fréquentes étaient en couple avec enfants (36 %) et en maison avec jardin (51 %). Quarante-sept pour cent rapportent une diminution de la qualité du sommeil en confinement. Les facteurs associés à une détérioration du sommeil retenus par l’analyse multivariée sont une diminution de la durée du sommeil (OR 15,52 — p < 0,001), un coucher plus tardif (OR 1,72 — p < 0,001), un lever plus matinal (2,18 — p = 0,01), des horaires plus irréguliers (OR 2,29 — p < 0,001), une diminution de l’exposition à la lumière du jour (OR 1,46 — p = 0,01) et une augmentation de l’utilisation des écrans le soir (OR 1,33 — p = 0,04).

Conclusion

La mauvaise qualité subjective du sommeil en confinement est associée à une modification des comportements relatifs au sommeil et de l’exposition à la lumière (moins de lumière du jour et plus d’écran le soir). Pour optimiser le sommeil en confinement, des horaires adaptés et réguliers, une exposition de plus d’une heure/jour à la lumière du jour et l’éviction des écrans le soir sont à conseiller.
