ObjectiveThis study aims to assess and compare demographic and psychological factors and sleep status of frontline healthcare workers (HCWs) in relation to non-frontline HCWs.Design, settings, participants and outcomesThis cross-sectional study was conducted from 8 April 2020 to 17 April 2020 using an online survey across varied healthcare settings in Oman accruing 1139 HCWs.The primary and secondary outcomes were mental health status and sociodemographic data, respectively. Mental health status was assessed using the Depression, Anxiety, and Stress Scale (DASS-21), and insomnia was evaluated by the Insomnia Severity Index. Samples were categorised into the frontline and non-frontline groups. χ2 and t-tests were used to compare groups by demographic data. The Mantel-Haenszel OR was used to compare groups by mental health outcomes adjusted by all sociodemographic factors.ResultsThis study included 1139 HCWs working in Oman. While working during the pandemic period, a total of 368 (32.3%), 388 (34.1%), 271 (23.8%) and 211 (18.5%) respondents were reported to have depression, anxiety, stress and insomnia, respectively. HCWs in the frontline group were 1.5 times more likely to report anxiety (OR=1.557, p=0.004), stress (OR=1.506, p=0.016) and insomnia (OR=1.586, p=0.013) as compared with those in the non-frontline group. No significant differences in depression status were found between the frontline and non-frontline groups (p=0.201).ConclusionsTo our knowledge, this is the first study to explore the differential impacts of the COVID-19 pandemic on different grades of HCWs. This study suggests that frontline HCWs are disproportionally affected compared to non-frontline HCWs, with managing sleep–wake cycles and anxiety symptoms being highly endorsed among frontline HCWs. As psychosocial interventions are likely to be constrained owing to the pandemic, mental healthcare must first be directed to frontline HCWs.

Objectives: This study aimed to provide an updated estimate of the prevalence of autism spectrum disorder (ASD) among Omani children. Methods: This retrospective descriptive study was conducted from December 2011 to December 2018. Data were retrieved from the three main autism diagnostic centres in Oman: Sultan Qaboos University Hospital, Royal Hospital and Al-Massarah Hospital. The ASD diagnosis was made by experienced clinicians based on the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The overall population prevalence estimates per 10,000 children aged 0–14 years old in Oman were calculated using the denominator of the mid-period population data. Results: A total of 1,705 ASD cases were identified with the majority of cases being male (78.1%). The overall prevalence rate of ASD was estimated at 20.35 per 10,000 children (95% confidence interval: 19.39–21.32) between 2012–2018. Boys were found to have a 3.4-fold higher prevalence of ASD than girls (31.23/10,000 versus 9.07/10,000). Regionally, the majority of cases were found in the capital, Muscat, where the highest prevalence was 36.51 cases per 10,000 children. Conclusion: The prevalence of ASD among Omani children is 15-fold higher than estimates from 2011. This increase can be attributed to improvements in diagnostic services, increased awareness of ASD, better screening programmes and changes in diagnostic criteria. In addition, this increase in prevalence suggests a need for a registry of developmental disabilities and more extensive diagnostic and rehabilitation services in Oman.Keywords: Autism Spectrum Disorder; Epidemiology; Prevalence; Oman.

Aim Despite the much heralded epidemic of adjustment difficulties, health‐care workers (HCW), who are likely to be at risk and impacted with mental health issues, have received scant attention. This study aimed to determine whether definable profiles exist in a cohort of HCWs associated with demographic and mental health problems. Methods An online cross‐sectional survey was conducted in Oman. Demographic and mental health data were collected from 8 to 17 April 2020. A total of 1132 participants returned their completed questionnaire. A two‐step cluster analysis was used to split the sample into three clusters. Results Cluster A ( n = 416) was from HCW in non‐frontline roles, and constituted “ low‐risk and least‐impacted ”. Cluster B ( n = 412) and Cluster C ( n = 304) were from frontline HCW and constituted ‘ high‐risk and moderate‐impacted ’ and ‘ high‐risk and high‐impacted ’ groups, respectively. HCWs in Cluster C reported more depression ( P < 0.001), anxiety ( P < 0.001), stress ( P < 0.001) and clinical insomnia ( P < 0.001) compared with those in the other clusters. HCWs in Cluster C were at the highest risk for mental health problems during the pandemic. Conclusions Early psychological interventions targeting this vulnerable group may be beneficial. Management should develop different tailor‐made strategic plans to address different mental health needs for each profile group.
