The effect of lockdowns and distant learning on the health-related behaviours of school students in the United Arab Emirates.

BACKGROUND: The COVID-19 pandemic began to affect the world in early 2020. As a preventive measure, schools in the UAE adopted remote learning. This study aimed to assess the effects of the lockdown and remote learning on the health-related behaviours of school students in the UAE. METHODS: A cross-sectional study using an online survey comprising 33 questions related to physical activity, eating, sleeping and screen time was answered by the students' parents. Chi-square tests, paired Student's t tests and frequency tables were used for analysis. RESULTS: A total of 27,754 responses were received: 46.3% of the parents indicated a significant decrease in physical activity; 44.6% indicated an increase in unhealthy snack consumption; and 51.9% indicated decreased food ordering from restaurants. The percentage of students who slept more than 9 hours and those who slept less than 6 hours increased. Screen time increased significantly for both educational and entertainment purposes (P value < 0.0001). CONCLUSION: The study showed changes in the lifestyle and health-related behaviours of school students as indicated by their parents. Risk factors such as a lack of physical activity, increased food consumption, sleeping and screen time were directly affected. Therefore, it is important to further investigate these changes and their effects to help design targeted health education programs and promotion campaigns.

Parents' views on the acceptability of a COVID-19 vaccine for their children: A cross-sectional study in Abu Dhabi-United Arab Emirates.

BACKGROUND: The United Arab Emirates had approved the COVID-19 vaccine for children. Assessing parents' acceptance of the vaccine for their children will influence decision-making in the COVID-19 vaccine roll-out. METHOD: Parents registered inthe AbuDhabiDepartmentofEducation (12,000 families) were invitedtocompleteanonlinequestionnaire from 8th September 2021 to 17th October 2021. Out of the 12,000 families, 2510 (21%) participants answered the survey. The questionnaire investigated the parents' attitudes and beliefs regarding the COVID-19 vaccine. RESULTS: The vaccination rate among this group of respondents was high, with 2255 (89.9%) having received two doses and 1002 (45.5%) having already received a booster dose. Acceptance of the respondents to vaccinate their children was high, (75.1%) said they would vaccinate their children, with 64.4% reporting that they would immediately vaccinate their children if the vaccine were made available. Determinants of COVID-19 child vaccination acceptance included the respondent's vaccination status-i.e., if the respondent is already vaccinated (OR 4.96 [2.89-8.53]) or has taken the third dose (OR 2.37 [1.4-4.01])-their children's age (OR 1.11 [1.30-1.18] for older children), and their trust in the following information sources: the government (OR 2.53 [1.61-3.98]), health care providers (OR 1.98 [1.2-3.24]), or social media (OR 2.17 [1.22-3.88]). Increased level of education had a negative impact on the acceptance of giving the vaccine to children (OR 0.63 [0.52-0.77]); fear of side effects OR 0.000164 (0.000039-0.001) was another determinant. The main factor that encouraged parents to give their children the vaccine was to protect their child's health as reported by 1537 (55.5%) participants. CONCLUSION: The Abu Dhabi community is highly accepting of the vaccine for their children. Future studies of how this vaccine acceptance can influence the pandemic are needed.

A Review of COVID-19 Mass Testing in the United Arab Emirates.

Appropriate diagnostic testing to identify persons infected with SARS-COV-2 is a vital part of a health system's ability to control the global pandemic of COVID-19 disease. The primary purpose of this review is to provide an overview of the mass testing strategy implemented throughout the UAE and the overall impact it has made on containing and controlling the spread of the disease. This study describes the mass testing strategy and capacity of the UAE during the pandemic of the new coronavirus SARS-COV-2. The UAE has conducted 15 million polymerase chain reaction (PCR) tests to SARS-COV-2, as of 15 November 2020. The number of tests per day varied from 10,000 by the end of March to 120,000 tests per day in November 2020. The mass testing initiative across the entire UAE forms an integral part of a bigger strategy focusing on testing, tracing contacts and isolating positive cases.

Seroprevalence of COVID-19 infection in the Emirate of Abu Dhabi, United Arab Emirates: a population-based cross-sectional study.

BACKGROUND: The United Arab Emirates (UAE) was the first country in the Middle East to report severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Serosurveys are essential to understanding the extent of virus transmission. This cross-sectional study aims to assess the seroprevalence of SARS-CoV-2 infection in the Emirate of Abu Dhabi. METHODS: Between 19 July and 14 August 2020, 4487 households were selected using a random sample stratified by region and citizenship of the head of household (UAE citizen or non-citizen). A cluster sample of 40 labour camps was selected. Data on socio-demographic characteristics, risk factors and symptoms compatible with coronavirus disease 2019 (COVID-19) were collected. Each participant was first tested by Roche Elecsys® Anti-SARS-CoV-2 assay, followed, when reactive, by the LIAISON® SARS-CoV-2 S1/S2 IgG assay. RESULTS: Among 8831 individuals from households, seroprevalence was 10·4% [95% confidence intervals (CIs) 9·5-11·4], with higher seroprevalence in Abu Dhabi and Al Ain regions compared with those in Al Dhafra. In households, we found no sex difference and UAE citizens had lower seroprevalence compared with those of other nationalities. Among 4855 workers residing in labour camps, seroprevalence was 68·6% (95% CI 61·7-74·7), with higher seroprevalence among workers from Southeast Asia. In households, individuals with higher body mass indexes demonstrated higher seroprevalences than individuals with normal weight. Anosmia and ageusia were strongly associated with seropositivity. CONCLUSIONS: The majority of household populations in the Emirate of Abu Dhabi remained unexposed to SARS-CoV-2. In labour camps, SARS-CoV-2 transmission was high. Effective public health measures should be maintained.

Epidemiological characterization of symptomatic and asymptomatic COVID-19 cases and positivity in subsequent RT-PCR tests in the United Arab Emirates.

The coronavirus disease 2019 (COVID-19) cases could be symptomatic or asymptomatic. We (1) characterized and analyzed data collected from the first cohort of reverse transcriptase polymerase chain reaction (RT-PCR)-confirmed COVID-19 cases reported in the Emirate of Abu Dhabi, United Arab Emirates, according to the symptomatic state, and (2) identified factors associated with the symptomatic state. The association between the symptomatic state and testing positive in three subsequent RT-PCR testing rounds was also quantified. Between February 28 and April 8, 2020, 1,249 cases were reported. Sociodemographic characteristics, working status, travel history, and chronic comorbidities of 791 cases were analyzed according to the symptomatic state (symptomatic or asymptomatic). After the first confirmatory test, the results of three subsequent tests were analyzed. The mean age of the 791 cases was 35.6 ± 12.7 years (range: 1-81). Nearly 57.0% of cases were symptomatic. The two most frequent symptoms were fever (58.0%) and cough (41.0%). Symptomatic cases (mean age 36.3 ± 12.6 years) were significantly older than asymptomatic cases (mean age 34.5 ± 12.7 years). Compared with nonworking populations, working in public places (adjusted odds ratio (aOR), 1.76, 95% confidence interval (95% CI): 1.11-2.80), healthcare settings (aOR, 2.09, 95% CI: 1.01-4.31), or in the aviation and tourism sectors (aOR, 2.24, 95% CI: 1.14-4.40) was independently associated with the symptomatic state. Reporting at least one chronic comorbidity was also associated with symptomatic cases (aOR, 1.76, 95% CI: 1.03-3.01). Compared with asymptomatic cases, symptomatic cases had a prolonged duration of viral shedding and consistent odds of ≥2 positive COVID-19 tests result out of the three subsequent testing rounds. A substantial proportion of the diagnosed COVID-19 cases in the Emirate of Abu Dhabi were asymptomatic. Quarantining asymptomatic cases, implementing prevention measures, and raising awareness among populations working in high-risk settings are warranted.
