Prevalence of hepatitis B and C viruses among migrant workers in Qatar.

Limited data exist on viral hepatitis among migrant populations. This study investigated the prevalence of current hepatitis B virus (HBV) infection and lifetime hepatitis C virus (HCV) infection among Qatar's migrant craft and manual workers (CMWs), constituting 60% of the country's population. Sera collected during a nationwide COVID-19 population-based cross-sectional survey on CMWs between July 26 and September 9, 2020, underwent testing for HBsAg and HCV antibodies. Reactive samples underwent confirmatory testing, and logistic regression analyses were employed to explore associations with HBV and HCV infections. Among 2528 specimens tested for HBV infection, 15 were reactive, with 8 subsequently confirmed positive. Three samples lacked sufficient sera for confirmatory testing but were included in the analysis through multiple imputations. Prevalence of current HBV infection was 0.4% (95% CI 0.2-0.7%). Educational attainment and occupation were significantly associated with current HBV infection. For HCV infection, out of 2607 specimens tested, 46 were reactive, and 23 were subsequently confirmed positive. Prevalence of lifetime HCV infection was 0.8% (95% CI 0.5-1.2%). Egyptians exhibited the highest prevalence at 6.5% (95% CI 3.1-13.1%), followed by Pakistanis at 3.1% (95% CI 1.1-8.0%). Nationality, geographic location, and occupation were significantly associated with lifetime HCV infection. HBV infection is relatively low among CMWs, while HCV infection falls within the intermediate range, both compared to global and regional levels.

Short-term side effects of BNT162b2 vaccine in primary care settings in Qatar: a retrospective study.

Background: Despite the established effectiveness of the BNT162b2 Vaccine, the novel technology demands careful safety monitoring. While global studies have explored its safety, local data remains limited and exhibits some variability. This study investigated short-term side effects among BNT162b2 vaccinated individuals in Qatar. Methods: A retrospective analysis was conducted using data extracted from the electronic health records of individuals aged 18 or older across 8 primary health centers who received either the first or second dose of the BNT162b2 vaccine during the period from December 23, 2020, to April 24, 2021. The proportions of individuals experiencing short-term side effects after each dose were calculated. Logistic regression and log binomial regression analyses were used to explore associations with the side effects. Results: Among 7,764 participants, 5,489 received the first dose and 2,275 the second, with similar demographics between the groups. After the first dose, 5.5% reported at least one local side effect, compared to 3.9% after the second, with a 1.4 times higher incidence after the first dose (RR 1.4, 95% CI 1.14-1.75) compared to the second. Systemic side effects after the second dose were 2.6 times more common than after the first (RR 2.6, 95% CI 2.15-3.14). Gender, nationality, history of prior COVID-19 infection, and obesity were significantly associated with side effects after the first dose, while age, gender, and nationality, were significant factors after the second dose. Conclusion: The rates of side effects following the BNT162b2 vaccine in Qatar were relatively low, with age, gender, nationality, previous infection, and obesity identified as significant predictors. These results emphasize the need for tailored vaccination strategies and contributes valuable insights for evidence-based decision-making in ongoing and future vaccination campaigns.

From classrooms to controllers: how school closures shaped children's video gaming habits.

OBJECTIVES: This study aimed to assess the impact of COVID-19-related school closures on screen time and video gaming habits among governmental school students in Qatar and explore the prevalence of Internet Gaming Disorder (IGD) within this context. METHODS: A cross-sectional approach was employed, spanning two months from June to August 2022. A random sample of students aged 8-15 years was drawn from the national electronic health record system of Qatar. Telephone interviews with parents were conducted to collect data. The Parental Internet Gaming Disorder Scale (PIGDS) was used for IGD assessment. RESULTS: Of 428 parents, 257 (60%) confirmed their child's engagement in video gaming during school closures. Participants averaged 11 years in age with 92 (35.8%) females and 165 (64.2%) males. Nationality included 62.6% expatriates and 37.4% Qatari locals. Average weekly screen time increased significantly from 19.7 ± 10.1 h to 31.9 ± 12.6 h during closure (p < 0.001). Video gaming time rose from 8.6 ± 8.6 h to 13.0 ± 12.4 h per week (p < 0.001). The prevalence of IGD was 8.6% (95% CI 5.4-12.7). Male students, expatriates, and those reporting increased video gaming time were more likely to develop IGD than their female and local counterparts. CONCLUSION: The observed associations between video gaming increase and IGD highlight the need for focused interventions to address potential risks and promote healthier digital habits among this population.

COVID-19 lockdowns weigh heavily on youth: an analysis of the impact on BMI for Age Z scores in children and adolescents.

BACKGROUND: The COVID-19 pandemic has significantly impacted the lifestyle and health of children and adolescents. This study aimed to assess the lifestyle changes brought about by COVID-19-related school closures and their impact on the Body Mass Index for Age Z (BAZ) scores of governmental school students in Qatar. METHODS: An analytical cross-sectional study was conducted between June and August 2022 targeting students aged 8-15 years. Data on lifestyle behaviors were gathered through telephone interviews with parents of selected students. The BAZ scores before and after school closures that were automatically calculated by the electronic health records system were extracted. RESULTS: We completed 1546 interviews. We found a significant increase in unhealthy food categories, a reduction in physical activity and an increase in the screen time over the period of schools' closure. The BAZ increased significantly by 0.30 (95% CI 0.26-0.35). The increase in BAZ scores was significantly higher among male students and the younger age group compared to females and older counterparts, respectively. The student's age group, sex, nationality and change in physical activity were significant predictors of the change in BAZ scores. CONCLUSIONS: School closures during the COVID-19 pandemic negatively impacted the lifestyle of students in Qatar and resulted in a significant increase in the BAZ scores.

Computer vision syndrome among students during remote learning periods: harnessing digital solutions for clear vision.

Aim: This study aimed to assess the prevalence of Computer Vision Syndrome (CVS) among children and adolescents in Qatar during the period of remote learning and explore the associated factors and discuss some digital health remedies that might reduce the risk. Methods: We conducted an analytical cross-sectional study between June and August 2022 by collecting data via telephone interviews with parents of selected students utilizing the Computer Vision Syndrome Questionnaire (CVS-Q). Results: We completed 1,546 interviews. The mean age of the students was (11 ± 2), male: female ratio was almost 1:1. About one quarter (368, 23.8%) of parents reported a previous diagnosis of visual disturbances among their children with over 88% of them wearing eyeglasses or medical contact lenses. The prevalence of CVS in our sample was about 8% (95%CI: 6.8-9.6). Mother's employment, having positive history of visual disturbances, and excess screen time were found to be significant predictors of CVS. Conclusion: Health care providers in collaboration with teachers should provide parents with evidence-based strategies to prevent or minimize the digital eye strain among students. In the landscape of remote learning, the implementation of digital remedies emerges as a proactive approach to mitigate the risk of digital eye strain.

The Triple "S" Impact of COVID-19: Nationwide Evidence of the Impact of the Stress Associated With Restrictive Measures on Substance Use, Sleep, and Social Connectedness in Qatar.

OBJECTIVES: Countries worldwide implemented social and movement restrictions to contain the spread of coronavirus disease 2019 (COVID-19). Unfortunately, such restrictions have adversely impacted people's lifestyles. The goal of this study was to assess the impact of COVID-19-related restrictive measures on substance use, sleep, and social connectedness in Qatar's population. METHODS: A web-based survey was conducted between January 2021 and February 2021 targeting adults ≥18 years of age who were residing in Qatar between March and August 2020. RESULTS: A total of 1408 participants completed the survey. Of tobacco users in our sample, 36% reported increased tobacco use since the start of home confinement, while 41.6% of alcohol users reported decreased alcohol use. Concerning sleep, 46.1% reported an increase in average sleep duration per day (0.77 h mean increase, 95% CI: 0.66-0.88, P<0.001), and a third of participants reported poorer sleep quality. Of the participants, 39.6% felt socially disconnected. Perceived stress was found to be an independent predictor for increased use of tobacco, deterioration in sleep quality, and increased sleep duration during home confinement. CONCLUSIONS: Restrictive measures related to COVID-19 resulted in both positive and negative impacts on the lifestyle of Qatar's population. Emphasis should be placed on encouraging people to adopt healthy strategies for coping with various stressors that arise during future home confinement measures. It is also necessary to address the persistence of adverse consequences in the postpandemic era.

Seroprevalence of herpes simplex virus type 1 and type 2 among the migrant workers in Qatar.

BACKGROUND: Limited data exists on herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) infections in migrant populations. This study investigated HSV-1 and HSV-2 seroprevalences and associations among craft and manual workers (CMWs) in Qatar who constitute 60% of Qatar's population. METHODS: A national population-based cross-sectional seroprevalence survey was conducted on the CMW population, all men, between July 26 and September 9, 2020. 2,612 sera were tested for anti-HSV-1 IgG antibodies using HerpeSelect 1 ELISA IgG kits and for anti-HSV-2 IgG antibodies using HerpeSelect 2 ELISA IgG kits (Focus Diagnostics, USA). Univariable and multivariable logistic regression analyses were conducted to identify associations with HSV-1 and HSV-2 infections. RESULTS: Serological testing identified 2,171 sera as positive, 403 as negative, and 38 as equivocal for HSV-1 antibodies, and 300 sera as positive, 2,250 as negative, and 62 as equivocal for HSV-2 antibodies. HSV-1 and HSV-2 seroprevalences among CMWs were estimated at 84.2% (95% CI 82.8-85.6%) and 11.4% (95% CI 10.1-12.6%), respectively. HSV-1 infection was associated with nationality, educational attainment, and occupation. HSV-2 infection was associated with age, nationality, and educational attainment. CONCLUSIONS: Over 80% of CMWs are infected with HSV-1 and over 10% are infected with HSV-2. The findings highlight the need for sexual health programs to tackle sexually transmitted infections among the CMW population.

A Sociodemographic Analysis of the Impact of COVID-19-Related Schools' Closure on the Diet and Physical Activity of Children and Adolescents in Qatar.

OBJECTIVES: To assess the impact of the COVID-19-related closure of government schools in Qatar on children and adolescents' dietary habits and physical activities and associated sociodemographic factors. METHODS: An analytical cross-sectional study was conducted between June and August 2022 utilizing the national electronic health records system in Qatar to extract a sampling frame of students enrolled in governmental schools, specifically targeting students in 3rd to 9th grades, stratified by sex and developmental stage. A stratified sampling technique was employed to randomly select a proportionate number of students from each stratum, and data were collected through telephone interviews with the parents of selected students. RESULTS: A total of 1546 interviews were completed by the end of the study. Of the included sample, 845 (54.7%) were between 8 and 11 years of age (middle childhood), while the rest were 12-15 years old (young teens and teenagers). Male to female ratio was almost 1:1. We found a significant decrease in the intake of vegetables, increases in the intake of soft drinks, fried food, fast food, and sweets, and a reduction in physical activity during schools' closure compared to before. Higher parental educational levels, maternal employment, and having a positive family history of obesity and/or overweight in first-degree relatives were significantly associated with adverse lifestyle changes during schools' closure. CONCLUSION: The trends of lifestyle changes reported in this study during the periods of COVID-19-related schools' closure were found to be going in a health-compromising direction. These results underscore the importance of implementing targeted interventions to promote healthy lifestyles during such disruptions and emphasize the need to address lifestyle changes beyond emergencies and outbreaks to mitigate potential long-term health consequences, including the increased risk of non-communicable diseases.

Sickness absenteeism among primary health care workers in Qatar before and during the COVID-19 pandemic.

OBJECTIVES: To explore the patterns, trends, nature, and extent of changes in sickness absence among health care workers (HCWs) at the Primary Health Care Corporation (PHCC) in Qatar-during the COVID-19 pandemic compared to previous years and uncover the main associated factors. METHODS: We conducted a retrospective analysis of all sick leaves' records of PHCC HCWs regardless of their profession from January 2019 till August 2021. RESULTS: A total of 41,132 sick leaves were taken during the studied period. The majority of HCWs who availed sick leaves were between 30-39 years (45.9%), females (65.1%), and expatriates (65.1%). Compared with pre-COVID-19 (Jan 2019-Feb 2020), Wave 1 of COVID-19 had significantly less incidence of sick leaves per day per 1000 HCWs. While wave 2 had significantly higher incidence of sick leaves compared to both pre-COVID-19 and wave 1. The number of sick leaves per person among female HCWs was significantly higher than that of male HCWs. Moreover, the number of sick leaves per person among locals were about two times the number among expatriate HCWs. Physicians and nurses had significantly lower number of sick leave per person compared to other professions. The rates of sick leaves due to suspected or confirmed COVID-19 infection, back/neck pain and gastroenteritis were significantly higher in the second wave compared to the first wave of COVID-19. CONCLUSION: Overall and cause specific sick leave rates among HCWs varied significantly across different periods of the COVID-19 pandemic. COVID-19 related sick leave rate was higher during the second wave compared to first one. By addressing the root causes of sick leaves, it is possible to reduce the burden on HCWs and ensure their continued ability to provide essential care to those in need.

Effectiveness of influenza vaccination against SARS-CoV-2 infection among healthcare workers in Qatar.

BACKGROUND: Some studies have reported that influenza vaccination is associated with lower risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and/or coronavirus disease 2019 (COVID-19) morbidity and mortality. This study aims to estimate effectiveness of influenza vaccination, using Abbott's quadrivalent Influvac Tetra vaccine, against SARS-CoV-2 infection and against severe COVID-19. METHODS: This matched, test-negative, case-control study was implemented on a population of 30,774 healthcare workers (HCWs) in Qatar during the 2020 annual influenza vaccination campaign, September 17, 2020-December 31, 2020, before introduction of COVID-19 vaccination. RESULTS: Of 30,774 HCWs, 576 with PCR-positive tests and 10,033 with exclusively PCR-negative tests were eligible for inclusion in the study. Matching by sex, age, nationality, reason for PCR testing, and PCR test date yielded 518 cases matched to 2058 controls. Median duration between influenza vaccination and the PCR test was 43 days (IQR, 29-62). Estimated effectiveness of influenza vaccination against SARS-CoV-2 infection> 14 days after receiving the vaccine was 29.7% (95% CI: 5.5-47.7%). Estimated effectiveness of influenza vaccination against severe, critical, or fatal COVID-19 was 88.9% (95% CI: 4.1-98.7%). Sensitivity analyses confirmed the main analysis results. CONCLUSIONS: Recent influenza vaccination is associated with a significant reduction in the risk of SARS-CoV-2 infection and COVID-19 severity.

This event is an opportunity for people around the world to socialize, connect, celebrate, and enjoy watching football matches. However, the emotional stress experienced by football players and fans during a such major sport event can sometimes result in unfavorable physiological responses that can adversely affect the heart leading to adverse cardiac consequences. In this mini-review, we summarized the evidence and pathophysiology of stress-induced cardiac events during football games, and the potential strategies to prevent stress-induced cardiac events during the FIFA World Cup 2022.

Occupational Prevention of COVID-19 Among Healthcare Workers in Primary Healthcare Settings: Compliance and Perceived Effectiveness of Personal Protective Equipment.

OBJECTIVES: It is crucial for healthcare workers (HCWs) to comply with infection prevention and control precautions such as the appropriate use of personal protective equipment (PPE) for their safety and the safety of patients. In this study, we aimed to assess HCWs' compliance with the appropriate use of PPE in primary healthcare settings in Qatar along with its associated factors and explore their perceived effectiveness of different PPE items in protecting against COVID-19 infection. METHODS: A Web-based survey was conducted between November 2020 and January 2021 targeting all clinical HCWs under the umbrella of Primary Health Care Corporation. RESULTS: A total of 757 HCWs completed the survey, and most were between 30 and 39 years of age (50.2%), females (62.7%), and nurses (35.3%). Eighty eight percent of participants believed that PPE could provide high or very high protection against COVID-19. About one-half (53%) were found to be fully compliant with PPE use during patient interactions with suspected or confirmed COVID-19 cases, whereas three-quarters (76.3%) were fully compliant while performing aerosol-generating procedures. Healthcare workers' age, nationality, health center region, area of work, clinical experience, frequency of interaction with suspected or confirmed COVID-19 cases, and the perceived effectiveness of PPE were significant predictors of full compliance with PPE. Shortage of PPE was the commonest reported barrier to appropriate use. CONCLUSIONS: Despite HCWs' high perceived effectiveness for PPE in protecting against COVID-19 infection, their full compliance rate with using PPE was moderate and needs further improvement.

Barriers to Practicing COVID-19 Preventive Behaviors Among Migrant Workers in Qatar: A Qualitative Study During the First Wave of the Pandemic.

Objectives: Manual and Craft Workers (MACWs), who constitute more than 80% of the population, were identified to be a vulnerable group to COVID-19 in Qatar. The goal of this study is to identify the limitations face MACWs in Qatar towards practicing the COVID-19 preventive measures and thereby designing behavioral change strategies. Methods: This is a qualitative research study in which individual interviews and focus group discussions were utilized for a deep understanding of the phenomenon from key informants. Four onlive individual interviews and four focus groups (n = 55) were conducted and transcribed verbatim. Inductive qualitative analysis was followed to discover the themes of the interviews. Data were analyzed using constant comparative techniques. Results: Major themes elicited from the analysis revealed that the barriers to following COVID-19 preventive behaviors among migrant workers in Qatar included barriers related to knowledge and risk perception; lifestyle and habits; nature of work and living conditions, and barriers related to health communication, diversified cultures, and languages. Conclusion: The findings would support constructing culturally sensitive health education messages and planning for effective health communication campaigns.

The story behind the first few cases of monkeypox infection in non-endemic countries, 2022.

Starting May 6, 2022, a rising number of monkeypox cases started to be detected in different countries where the disease is not endemic. About 24 countries reported cases by May 28 mostly in Europe. Most of the reported cases so far were among young men particularly men who have sex with men or had a travel history to countries where cases are being registered. In this rapid review we summarized the story behind the first few cases of monkeypox virus infection in non-endemic countries and the prevention measures implemented so far by countries to contain the spread of the disease.

The Impact of Changes in Work Arrangements During COVID-19 Pandemic on the Lifestyle of Qatar's Working Population.

OBJECTIVES: To explore the impact of changing work arrangements during COVID-19 on diet, physical activity, body weight, and sleep of Qatar's working population. METHODS: A web-based survey targeting working adults who were residing in Qatar during the period of home confinement was conducted. RESULTS: About 47% of 1061 participants reported weight gain. Higher proportions of participants reported consuming more fatty foods (P = 0.007), more sugary foods (P = 0.001), and greater increase in screen and sitting/reclining times (P < 0.001) among the work from home (WFH) group. Participants with higher adverse dietary changes score were more likely to report weight gain in both the WFH (adjusted OR 1.38, 95% CI 1.28 to 1.49), and working regularly groups (adjusted OR, 1.31, 95% CI 1.20 to 1.43) with P < 0.001. CONCLUSION: Qatar's working population experienced adverse lifestyle changes which were more prominent among those who shifted to WFH.

Knowledge and Perceived Effectiveness of Infection Prevention and Control Measures Among Health Care Workers During the COVID-19 Pandemic: A National Survey.

BACKGROUND: Being the first line of defense against COVID-19 infection, health care workers (HCWs) are at an increased risk of getting infected. Infection prevention and control (IPC) measures were deemed to be instrumental in protecting them and their patients against infection. PURPOSE: To assess HCWs' knowledge of IPC measures and their perceived effectiveness in protecting against COVID-19. METHODS: A national web-based survey was conducted in different health care sectors in Qatar. RESULTS: A total of 1757 HCWs completed the survey. HCWs believed in applying stricter IPC precautions while dealing with confirmed COVID-19 cases than with suspected cases. Males and physicians were more likely to have high perceived effectiveness of IPC measures than females, nurses, and pharmacists. Higher proportions of HCWs believed in the effectiveness of hand hygiene than most types of personal protective equipment. CONCLUSION: Further research is recommended to assess the impact of HCWs' knowledge and perceived effectiveness of IPC measures on their compliance.

Impact of COVID-19 related home confinement measures on the lifestyle, body weight, and perceived glycemic control of diabetics.

BACKGROUND: People with Diabetes Mellitus are at high risk of encountering COVID-19 infection and are more vulnerable to the negative repercussions of this infection. In this study we aimed to explore the impact of COVID-19 related home confinement measures on physical activity, dietary habits, body weight and perceived glycemic control of adults with type 2 Diabetes Mellitus (T2DM) in Qatar. METHODS: A cross sectional web-based survey was conducted between January and February 2021 targeting adults ≥18 years with T2DM. RESULTS: Over 40% of the participants reported unhealthy dietary changes. We found a significant increase in the sitting/reclining, and screen times. One third of the participants reported weight gain, while one fifth reported poorer glycemic control since the start of home confinement measures. We found that reporting at least one unhealthy dietary change (p < 0.001) and being a female (p = 0.002) were significantly associated with reporting greater weight gain. Participants who reported five unhealthy dietary behaviours were more than seven times more likely to perceive poorer glycemic control during home confinement measures compared to those who did not report any unhealthy changes (OR: 7.27, 95%CI 1.60-33.5, p = 0.011). CONCLUSION: Adults with T2DM experienced adverse lifestyle changes during COVID-19 related home confinement measures. Further research is needed to investigate the persistence of such changes in the post pandemic era.

Impact of staying at home measures during COVID-19 pandemic on the lifestyle of Qatar's population: Perceived changes in diet, physical activity, and body weight.

Countries worldwide imposed different swift protective measures such as movement restrictions and staying at home measures to mitigate the spread of COVID-19. Despite the benefits gained from such measures in containing the spread of the infection, adverse lifestyle consequences happened. In this study we aimed to assess the impact of staying at home measures imposed during COVID-19 pandemic on dietary behaviors, physical activity, and body weight in Qatar's population. A population based cross sectional survey was conducted between December 2020 and February 2021 targeting adults ≥18 years. A total of 1408 participants completed the survey in four languages. Concerning the overall diet perception, 27.8%, and 33.2% perceived that their overall diet has become less healthy, or healthier respectively, since the start of staying at home measures. Almost half of all participants reported weight gain. Participants reported increased sitting/reclining time (1.94 h/day mean increase), screen times (2.05 h/day mean increase) with p < 0.001, and decreased exercise time (0.11 h/day mean reduction) with p < 0.001. The ordinal logistic regression analysis showed that the numbers of unhealthy dietary behaviors adopted by participants, and adverse changes in exercise, setting/reclining and screen times were significantly associated with weight gain. The results of this study indicate that peoples in Qatar have experienced adverse lifestyle changes with regard to their diet, physical activity, and body weight. More emphasis should be put on encouraging people to maintain healthy lifestyle behaviors during home confinement measures that might be imposed during any public health crises or any potential future outbreaks.

SARS-CoV-2 Infection Is at Herd Immunity in the Majority Segment of the Population of Qatar.

BACKGROUND: Qatar experienced a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) epidemic that disproportionately affected the craft and manual worker (CMW) population, who comprise 60% of the total population. This study aimed to assess ever and/or current infection prevalence in this population. METHODS: A cross-sectional population-based survey was conducted during July 26 to September 09, 2020, to assess both anti-SARS-CoV-2 positivity through serological testing and current infection positivity through polymerase chain reaction (PCR) testing. Associations with antibody and PCR positivity were identified through regression analyses. RESULTS: The study included 2641 participants, 69.3% of whom were <40 years of age. Anti-SARS-CoV-2 positivity was 55.3% (95% CI, 53.3%-57.3%) and was significantly associated with nationality, geographic location, educational attainment, occupation, and previous infection diagnosis. PCR positivity was 11.3% (95% CI, 9.9%-12.8%) and was significantly associated with nationality, geographic location, occupation, contact with an infected person, and reporting 2 or more symptoms. Infection positivity (antibody and/or PCR positive) was 60.6% (95% CI, 58.6%-62.5%). The proportion of antibody-positive CMWs who had a prior SARS-CoV-2 diagnosis was 9.3% (95% CI, 7.9%-11.0%). Only seven infections were ever severe, and only 1 was ever critical-an infection severity rate of 0.5% (95% CI, 0.2%-1.0%). CONCLUSIONS: Six in every 10 CMWs in Qatar have been infected, suggestive of reaching the herd immunity threshold. Infection severity was low, with only 1 in every 200 infections progressing to be severe or critical. Only 1 in every 10 infections had been previously diagnosed, which is suggestive of mostly asymptomatic or mild infections.
