The multidimensional nature of attitudes towards preventive vaccinations - a cross-sectional survey among Poles aged 15-39 years.

OBJECTIVES: Vaccination skepticism and vaccination refusal both constitute global public health concerns. Systematic monitoring of public attitudes towards vaccination is crucial for maintaining a high vaccination coverage rate. The study aimed to identify and characterize homogenous social groups distinguished by attitudes toward preventive vaccinations. MATERIAL AND METHODS: Between October and November of 2021, a nationwide representative cross-sectional survey was conducted on a representative sample of 1560 inhabitants of Poland aged 15-39 years. The study questionnaire included 60 questions on public attitudes towards vaccines, vaccination, and the COVID-19 pandemic. Factor analysis was applied to identify the main dimensions of vaccination attitudes. RESULTS: Factor analysis included 22 variables and yielded 3 factors or dimensions that accounted for 48.5% of the model's variability. Young adults were assigned into 6 homogeneous groups based on these factors: 1) general trust in vaccination, 2) vaccine safety concerns, 3) trust in fake medical news regarding COVID-19 vaccination, and denying the COVID-19 pandemic. Groups I-IV differed by sociodemographic factors and vaccination coverage rates. Nearly 60% of the respondents expressed concern regarding various aspects of vaccination. CONCLUSIONS: Most of Poland's young adults lack clearly defined attitudes towards vaccination. Attitudes towards vaccination can be divided into 6 heterogeneous groups.

Health Care Organization in Poland in Light of the Refugee Crisis Related to the Military Conflict in Ukraine.

BACKGROUND: Poland is witnessing a migration crisis caused by the ongoing military conflict in Ukraine. In addition to housing and necessities, 1.8 million Ukrainians that had taken refuge in Poland must have access to medical care. We aim to propose a strategy for implementing the changes in the Polish health care system in response to the Ukrainian refugee crisis. METHODS: A literature review on organizational changes in the functioning of health care systems during the migration crises worldwide in recent years and brainstorming in order to develop a strategy for implementing changes in the Polish health care system in response to the Ukrainian refugee crisis. RESULTS: The proposed strategy for implementing the changes in the Polish health care system is based on building health care resilience and adaptation to different crises. The operational objectives of organization-related activities are: (1) preparation of medical facilities to provide help for refugees, (2) development and implementation of the communication system, (3) implementation of available digital solutions, (4) organization of the diagnostic and medical services, (5) and implementation of changes in the management of medical facilities. CONCLUSIONS: Urgent reorganization is required to respond to an unavoidable increase in the demand for health care services.

Smoke-free homes in Poland during the COVID-19 pandemic - a nationwide cross-sectional survey.

OBJECTIVES: Secondhand smoke exposure causes serious health problems. Banning smoking in public venues decreases exposure to secondhand smoke. However, the implementation of smoke-free rules in a private setting (including homes) is largely voluntary. This study aimed to assess the prevalence and characteristics of voluntary smoke-free home rules in Poland during the COVID-19 pandemic as well as to identify factors associated with the voluntary implementation of smoking bans at home. MATERIAL AND METHODS: This cross-sectional survey was conducted in March 2022 with a nationally representative sample of 1090 individuals aged ≥18 years in Poland. Data were collected using a computerassisted web interviewing (CAWI) technique. The research tool was an original questionnaire developed for the purpose of this study. RESULTS: Nationally, 60.6% of individuals had total ban on smoking in home (100% smoke-free home rules), 34.0% had implemented a partial smokefree home rule and 5.4% had not implemented any smoke-free home rules. Over three-quarters of non-smokers (76.8%) and only one-fifth of smokers (20.7%) had adopted a full smoke-free home rule. In multivariate logistic regression analysis, males (OR = 1.65, 95% CI: 1.22-2.22, p < 0.01), non-smokers (OR = 13.78, 95% CI: 9.80-19.38, p < 0.001), respondents who had higher education (OR = 1.57, 95% CI: 1.15-2.14, p < 0.01) as well as those who lived alone (OR = 2.44, 95% CI: 1.52-3.90, p < 0.001) had higher odds of having a 100% smoke-free home rule. CONCLUSIONS: This study demonstrated the negative impact of the COVID-19 pandemic on the implementation of smoke-free home rules in Poland. Less than two-thirds of the Polish population has adopted a total smoke-free home rule, with significant gaps between smokers and nonsmokers. Information on current voluntary smoke-free rules will be useful for further implementation of the smoke-free law in Poland. Int J Occup Med Environ Health. 2023;36(1):84-95.

Barriers to accessing health services during the COVID-19 pandemic in Poland: A nationwide cross-sectional survey among 109,928 adults in Poland.

Introduction: The COVID-19 pandemic has significant socio-economic implications for numerous industries, including healthcare. Disruptions of essential health services were reported by nearly all countries around the world. A detailed assessment of the healthcare uptake is necessary to estimate the potential health effects of the COVID-19 pandemic on the population. This study aimed to assess the prevalence of barriers to accessing health services during the COVID-19 pandemic in Poland as well as to identify factors associated with the disturbed access to healthcare during the pandemic. Methods: This cross-sectional survey was carried out among Internet users in Poland using the computer-assisted web interview technique. Data were collected between October and December 2021. The questionnaire included 32 questions on sociodemographic characteristics, the COVID-19 pandemic, health status, daily habits as well as the use of healthcare during the COVID-19 pandemic. Results: Data were obtained from 102928 adults, the mean age was 48.0 ± 14.2 years, and 57.2% were females. Most of the respondents had visited a doctor during the past 12 months (70.4%). Almost half of adults in Poland (49.7%) reported barriers to access health services in the past 12 months. Out of 51,105 respondents who had experienced barriers to accessing health services during the COVID-19 pandemic, only 54.3% had visited a doctor in the past 12 months. Long waiting time (39.5%) and temporary closure of healthcare facilities/transformation into a COVID-19 dedicated center (28.8%) were the most common barriers indicated by the respondents. In multivariable logistic regression, female gender, age 18-49 years, lack of higher education, living in cities between 51,000 and 200,000 residents or above 500,000 residents, and having at least one chronic disease were significantly (p < 0.05) associated with higher odds of experiencing barriers to accessing health services during the COVID-19 pandemic. Conclusions: This study confirmed that the COVID-19 pandemic has worsened access to health services in Poland. During the pandemic, new barriers to accessing health services, such as the temporary closure of healthcare facilities for non-COVID patients were revealed. Findings from this study provided patients' perspectives on barriers to accessing health services in Poland that may be used by policymakers to reduce health inequalities.

Assessment of Hospital Volume in the Surgical Management of Endometrial and Ovarian Cancer: A Polish Population-Based Study.

BACKGROUND Surgery is a cornerstone in management of ovarian and endometrial cancer. The European Society of Gynecological Oncology introduced quality indicators to improve management of these cancers. The optimal annual number of surgeries per unit was established for high-quality surgical treatment. MATERIAL AND METHODS The database of the National Health Fund on surgical management of endometrial and ovarian cancer was analyzed. Patients treated between 2017 and 2020 were included. Departments where patients underwent surgery were divided according to number of surgeries performed per year in endometrial cancer: ≥80, 79-50, 49-20, 19-0; and ovarian cancer: ≥100, 99-50, 49-20, 19-0. Optimal number of surgeries per center was defined as at least 100 and 80 surgeries per year in ovarian and endometrial cancer, respectively. RESULTS Totally, there were 22 325 surgeries in 316 units and 10 381 surgeries in 251 units due to endometrial and ovarian cancer, respectively. Most surgeries in endometrial cancer (n=15 077; 67.5%) and ovarian cancer (n=9642; 92.88%) were performed in departments that did not meet optimal criteria in number of surgeries. Between 2017 and 2019, an increasing trend in number of surgeries per year in endometrial and ovarian cancer was found. In 2020, there was a decrease in the number of surgeries by 7.8% (n=453) and 8.6% (n=234) in endometrial and ovarian cancer, respectively. CONCLUSIONS In Poland, surgical treatment of ovarian and endometrial cancer is decentralized. Most cancer patients underwent surgery in low-volume general gynecologic departments. The COVID-19 pandemic impaired cancer management, leading to a decreased number of surgeries.

Screening for SARS-CoV-2 Infection in Students at the Medical University of Warsaw, Poland Between November 15 and December 10, 2021 Using a Single Lateral Flow Test, the Panbio™ COVID-19 Ag Rapid Test.

BACKGROUND Education was significantly affected by the coronavirus disease 2019 (COVID-19) pandemic, caused by the SARS-CoV-2 virus. Online learning affects the quality of learning as well as the mental health status of students. Regular screening for COVID-19 may be crucial to provide practical classes during the pandemic. The present study aimed to analyze the usefulness of rapid antigen tests for on-campus COVID-19 screening in real-life conditions at a medical university in Poland. MATERIAL AND METHODS This screening study was carried out among students attending practical classes at the Medical University of Warsaw, Poland between November 15 and December 10, 2021, during which a series of rapid antigen tests (Panbio™ COVID-19 Ag Rapid Test Device, nasal) were performed by healthcare professionals (nurses). Out of 104 student groups selected for the study (n=1847 students), 423 individuals from 63 student groups were tested at least once (22.9% response rate). A total of 2295 samples were collected. RESULTS Among the participants, 3.4% (n=15) had positive test results. Out of 15 COVID-19 cases, 14 were vaccinated. At least 1 positive COVID-19 case was detected in 8 student groups. In 3 student groups, we observed ≥2 infections that occurred at intervals, which may suggest student-to-student SARS-CoV-2 transmission. CONCLUSIONS This study produced real-world data from a COVID-19 screening study and confirmed the usefulness of the rapid antigen test (Panbio™ COVID-19 Ag Rapid Test Device nasal) for on-campus COVID-19 screening prior to practical classes. Maintaining a high percentage of participants is crucial to ensuring the effectiveness of on-campus COVID-19 screening.

Preventive Health Screening during the COVID-19 Pandemic: A Cross-Sectional Survey among 102,928 Internet Users in Poland.

Preventive screening is a highly cost-effective public health intervention. The COVID-19 pandemic may impact preventive healthcare services. This study aimed to assess the frequency of preventive health screening, as well as to identify the factors associated with compliance with health screening guidelines among adults in Poland during the COVID-19 pandemic. This cross-sectional survey was carried out between October and December 2021, among Internet users in Poland. Respondents were asked about the last date that they performed seven different screening tests. Completed questionnaires were obtained from 102,928 adults aged 18-99 years, and 57.2% were female. The most common screening tests performed in the past 12 months were blood pressure measurement (83%), blood count (66.2%), and blood sugar (63.3%). Moreover, more than half of respondents had a urinalysis (53.1%) and lipid panel (55.1%) in the past 12 months. Out of 58,904 females, 69.2% had a cervical cytology in the past 3 years. Older age, having higher education, living in urban areas, being occupationally active, having at least one chronic disease, and visiting a doctor in the past 12 months were significantly associated (p < 0.001) with a higher level of compliance with screening guidelines. This study revealed a significant gap in the performance of preventive health screening.

The Prevalence of Tobacco, Heated Tobacco, and E-Cigarette Use in Poland: A 2022 Web-Based Cross-Sectional Survey.

Monitoring tobacco use on a regular schedule is a basic tool of tobacco control policy. This study aimed (1) to assess the current prevalence and patterns of tobacco and e-cigarette use, as well as (2) to identify socioeconomic factors associated with smoking behavior among adults in Poland. This cross-sectional study was carried out in March 2022 on a nationwide, representative sample of 1090 adults in Poland. The computer-assisted web interview (CAWI) technique was used. Daily tobacco smoking was declared by 28.8% of respondents (27.1% of females and 30.8% of males; p = 0.2) and 4.2% were occasional smokers (4.2% of females and 4.3% of males; p = 0.8). Most of the current smokers (62.1%) smoked regular cigarettes and 25.2% smoked hand-rolled cigarettes. The prevalence of daily e-cigarette use was 4.8% (4.0% among females and 5.6% among males; p = 0.2). Daily heated tobacco use was declared by 4.0% of respondents (5.1% of females and 2.9% of males; p = 0.07). Age, having children, and educational level were significantly associated with current daily tobacco smoking. This study revealed a high prevalence of tobacco and e-cigarette use among adults in Poland. The presented data underscore the importance of further improvements in adopting a comprehensive tobacco control strategy in Poland.

Prevalence and Sociodemographic Factors Associated with Overweight and Obesity among Adults in Poland: A 2019/2020 Nationwide Cross-Sectional Survey.

Detailed characteristics of the weight status of the population is necessary for the effective prevention of health disorders, e.g., through personalized nutrition education. This study aimed to characterize weight status and identify sociodemographic factors associated with overweight/obesity in a representative sample of adult inhabitants of Poland. This cross-sectional study was carried out from July 2019 to February 2020 on a representative nationwide sample of individuals aged 18+ in Poland. The study consisted of two parts: questionnaire survey and anthropometric measurements. The body mass index was calculated. Data on 1831 adults (50.3% females; mean age 51.7 ± 19.9 years) were included in this analysis. The prevalence of overweight was 42.2% (52.4% among males and 32.0% among females). Of the 1831 participants, 16.4% were obese (16.5% of males and 16.2% of females). Out of 11 factors analyzed in this study, only 5 were significantly associated with overweight/obesity. Males, older participants, occupationally active individuals, those living in rural areas and individuals with at least one chronic disease had greater odds of overweight/obesity. This study demonstrated a high prevalence of overweight and obesity among adults in Poland. This is the most up-to-date representative study on nutritional status carried out before the COVID-19 pandemic.

HPV Vaccination: Polish-Language Facebook Discourse Analysis.

Social media platforms are widely used for spreading vaccine-related information. The objectives of this paper are to characterize Polish-language human papillomavirus (HPV) vaccination discourse on Facebook and to trace the possible influence of the COVID-19 pandemic on changes in the HPV vaccination debate. A quantitative and qualitative analysis was carried out based on data collected with a tool for internet monitoring and social media analysis. We found that the discourse about HPV vaccination bearing negative sentiment is centralized. There are leaders whose posts generate the bulk of anti-vaccine traffic and who possess relatively greater capability to influence recipients' opinions. At the beginning of the COVID-19 pandemic vaccination debate intensified, but there is no unequivocal evidence to suggest that interest in the HPV vaccination topic changed.

The Prevalence of Acute Respiratory Distress Syndrome (ARDS) and Outcomes in Hospitalized Patients with COVID-19-A Study Based on Data from the Polish National Hospital Register.

Acute respiratory distress syndrome (ARDS) is a serious complication of COVID-19. This study aimed to evaluate the prevalence of ARDS among patients hospitalized with COVID-19 in Poland as well as to characterize clinical outcomes in patients hospitalized with COVID-19-associated ARDS. This is a retrospective, secondary analysis of epidemiological data from 116,539 discharge reports on patients hospitalized with COVID-19 in Poland between March and December 2020. The overall prevalence of ARDS was 3.6%, respectively 2.9% among females, and 4.4% among males (p < 0.001). Of the 4237 patients hospitalized with COVID-19-associated ARDS, 3764 deaths were reported (88.8%). Participants aged 60 years and over had more than three times higher odds of COVID-19-associated ARDS. Men had higher odds of COVID-19-associated ARDS than women (OR = 1.55; 95% CI: 1.45-1.65; p < 0.001). Patients with COVID-19 and diabetes had higher odds of COVID-19-associated ARDS (OR = 1.16; 95% CI: 1.03-1.30; p = 0.01). Among patients with COVID-19-associated ARDS, older age, male sex (OR = 1.27; 95% CI: 1.03-1.56; p = 0.02), and presence of cardiovascular diseases (OR = 1.26; 95% CI: 1.00-1.59; p = 0.048) were significantly associated with the risk of in-hospital death. Among patients hospitalized with COVID-19 in Poland, the prevalence of ARDS was relatively low, but the in-hospital mortality rate in patients with COVID-19-associated ARDS was higher compared to other EU countries.

Factors Associated with Attitudes towards Seasonal Influenza Vaccination in Poland: A Nationwide Cross-Sectional Survey in 2020.

We aimed to assess attitudes towards the influenza vaccine and factors associated with a willingness to vaccinate against seasonal influenza in Poland during the COVID-19 pandemic (flu season 2020/2021). This cross-sectional questionnaire-based study was carried out between 5 and 15 November 2020 on a representative nationwide sample of 1052 individuals aged 18+ in Poland. Of the respondents, 5.5% (95% CI: 4.3-7.0%) declared that they had already got vaccinated against influenza and 13.4% (95% CI: 11.4-15.6%) declared a willingness to vaccinate against influenza during the 2020/2021 season. Out of nine different factors analyzed in this study, only three were significantly associated with attitudes towards influenza vaccination. Participants aged 75 years and over (OR = 5.82; 95% CI: 2.63-12.85), as well as participants aged 60-74 years (OR = 2.43; 95% CI: 1.30-4.54), compared to those aged 19-29, had significantly higher odds of having a positive attitude towards seasonal influenza vaccination. Respondents who define themselves as completely religious unbelievers (OR = 4.34; 95% CI: 1.79-10.55), as well as Internet users (OR = 2.12; 95% CI: 1.30-3.47), had higher odds of having a positive attitude towards influenza vaccination. Despite the COVID-19 pandemic, the percentage of adults in Poland who already got vaccinated or declared a willingness to vaccinate against influenza remains low. This also applies to high-risk groups.

Factors Associated with a Lack of Willingness to Vaccinate against COVID-19 in Poland: A 2021 Nationwide Cross-Sectional Survey.

We aimed to assess the factors associated with a lack of willingness to vaccinate against COVID-19 among adults in Poland three months after the introduction of mass vaccination against COVID-19 in Poland. This cross-sectional study was carried out between 8 and 18 April 2021 on a representative nationwide sample of 1131 inhabitants of Poland aged 18 and over. Almost one-third of adult inhabitants of Poland (30%; 95%CI: 27.4-32.7%) declared a lack of willingness to vaccinate against COVID-19. Females had higher odds of refusing COVID-19 vaccination compared with males (OR = 1.68; 95%CI: 1.25-2.27). The lack of higher education was significantly (p < 0.001) associated with greater odds of refusing the COVID-19 vaccination. Participants living in rural areas compared with those living in the largest cities (over 500,000 inhabitants) had three times higher odds of refusing the COVID-19 vaccination (OR = 3.20; 95%CI: 1.71-6.01). Respondents who declared willingness to vote for one of the right-wing political parties publicly supporting the anti-vaccination movement in Poland had eight times higher odds (OR = 8.01; 95%CI: 3.65-17.60) of refusing the COVID-19 vaccination compared with other groups. Moreover, those who had three children or more, respondents who declared passivity towards participating in religious practices as well as active internet users had significantly higher odds of refusing the COVID-19 vaccination.

Prevention of SARS-CoV-2 Infection Among Police Officers in Poland-Implications for Public Health Policies.

BACKGROUND: This study aimed to characterize sources of knowledge on the means of prevention of SARS-CoV-2 infections as well as to assess the methods of preventing SARS-CoV-2 infection among police employees in Poland and their potential impact on the risk of SARS-CoV-2 infection. METHODS: The study consisted of two phases: questionnaire and laboratory tests for SARS-CoV-2 infection. The questionnaire included 30 questions related to risk factors, knowledge about SARS-CoV-2, and methods of infection prevention. RESULTS: Data were obtained from 5082 police employees. The most common source of knowledge for a daily update on SARS-CoV-2 infection prevention was the Internet (42.6%), television (40.3%), and radio (39.7%). The most commonly used methods of SARS-CoV-2 infection included washing one's hands for at least 20 seconds (95.8%), wearing facemasks (82.9%), and physical distancing (74.9%). Results of IgG tests were lower in police units where the overall compliance with the preventive measures was higher (p < 0.01). Women were more likely to exercise SARS-CoV-2 infection prevention behaviors compared to men. Compliance with the recommended protective measures increased with age. CONCLUSIONS: Lower anti-SARS-CoV-2 IgG seropositivity rates were observed in police units with better overall compliance with the preventive measures, suggesting the key importance of group rather than individual behaviors.

Changes in Attitudes towards the COVID-19 Vaccine and the Willingness to Get Vaccinated among Adults in Poland: Analysis of Serial, Cross-Sectional, Representative Surveys, January-April 2021.

In December 2020, the first coronavirus disease 2019 (COVID-19) vaccine was authorized in the European Union. This study aimed to assess the changes in attitudes towards the COVID-19 vaccine and the willingness to get vaccinated among adults in Poland between January and April 2021. Secondary data analysis was carried out using data obtained from nationally representative cross-sectional surveys (four consecutive waves: January 2021, n = 1150; February 2021, n = 1179; March 2021, n = 1154; April 2021, n = 1131) carried out by the Public Opinion Research Center. About 31.3% of individuals declared a lack of willingness to vaccinate against COVID-19 regardless of the study wave. Significant changes (p < 0.001) were observed by gender and age. The highest percentage of respondents who declared a lack of willingness to vaccinate against COVID-19 was observed in the youngest age group (18-34 years), 48.5% among males and 45.6% among females. Among individuals over 65 years of age, males significantly more often declared their willingness to be vaccinated than females (p < 0.001). The main argument against the COVID-19 vaccine was concern about the potential side effects. Differences in attitudes towards the COVID-19 vaccine in respect of gender and age indicate the need to implement personalized communications to encourage different social groups to vaccinate against COVID-19.

Characteristics and Clinical Outcomes of 116,539 Patients Hospitalized with COVID-19-Poland, March-December 2020.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes Coronavirus Disease 2019 (COVID-19). This study aimed to characterize patients hospitalized with COVID-19 in Poland between March and December 2020, as well as to identify factors associated with COVID 19-related risk of in-hospital death. This retrospective analysis was based on data from the hospital discharge reports on COVID-19 patients hospitalized in Poland between March and December 2020. A total of 116,539 discharge reports on patients hospitalized with COVID-19 were analyzed. Among patients with COVID-19, 21,490 (18.4%) died during hospitalization. Patients over 60 years of age (OR = 7.74; 95%CI: 7.37-8.12; p < 0.001), men (OR = 1.42; 95%CI: 1.38-1.47; p < 0.001) as well as those with cardiovascular diseases (OR = 1.51; 95%CI: 1.46-1.56; p < 0.001) or disease of the genitourinary system (OR = 1.39; 95%CI: 1.31-1.47; p < 0.001) had much higher odds of COVID 19-related risk of in-hospital death. The presence of at least one comorbidity more than doubled the COVID 19-related risk of in-hospital death (OR = 2.23; 95%CI: 2.14-2.32; p < 0.01). The following predictors of admission to ICU were found in multivariable analysis: age over 60 years (OR: 2.03; 95%CI: 1.90-2.16), male sex (OR: 1.79; 95%CI: 1.69-1.89), presence of at least one cardiovascular disease (OR: 1.26; 95%CI: 1.19-1.34), presence of at least one endocrine, nutritional and metabolic disease (OR: 1.17; 95%CI: 1.07-1.28).

Prevalence of Current and Past SARS-CoV-2 Infections among Police Employees in Poland, June-July 2020.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We aimed to determine the prevalence of current and past SARS-CoV-2 infections among police employees. METHODS: This cross-sectional survey was undertaken among 5082 police employees from Mazowieckie Province, Poland. RT-PCR testing for current SARS-CoV-2 infection and serological tests (ELISA) for the presence of anti-SARS-CoV-2 IgM+IgA and IgG antibodies were performed. RESULTS: All RT-PCR tests were negative. The anti-SARS-CoV-2 IgM+IgA index was positive (>8) in 8.9% of participants, including 11.2% women and 7.7% men (p < 0.001). Equivocal IgM+IgA index (6-8) was found in 9.8% of participants, including 11.9% women and 8.7% men (p < 0.001). The IgG index was positive (>6) in 4.3% and equivocal (4-6) in 13.2% of participants. A higher odds of positive IgM+IgA index was found in women vs. men (OR: 1.742) and police officers vs. civilian employees (OR: 1.411). Participants aged ≥60 years had a higher odds of positive IgG index vs. those aged 20-29 years (OR: 3.309). Daily vaping also increased the odds of positive IgG index (OR: 2.058). CONCLUSIONS: The majority of Polish police employees are seronegative for SARS-CoV-2 infection. Vaping and older age (≥60 years) were associated with a higher risk of SARS-CoV-2 infection.

Dynamics of the coronavirus disease 2019 outbreak in Poland: an epidemiological analysis of the first 2 months of the epidemic.

INTRODUCTION: Coronavirus disease 2019 (COVID­19) is an infectious disease caused by the novel severe acute respiratory syndrome coronavirus 2. OBJECTIVES: Our aim was to present an epidemiological analysis of the first 2 months (March and April 2020) of the COVID­19 epidemic in Poland. PATIENTS AND METHODS: This analysis was based on data from epidemiological reports collected between March 4 and April 30, 2020, by the Chief Sanitary Inspectorate. These epidemiological reports include data on sociodemographic characteristics of new laboratory­confirmed COVID 19 cases, the number of COVID­19-related deaths, the number of recovered COVID-19 patients as well as the number of laboratory tests performed. RESULTS: From March 4 to April 30, 2020, a total of 12 877 laboratory­confirmed COVID 19 cases were registered in Poland (55.7% women; mean [SD] age, 50.6 [20.5] years). The RT­ PCR test was performed in 338 000 patients. The notification rate for COVID­19 was 33.2 per 100 000 inhabitants. One third of laboratory­confirmed COVID 19 cases were among quarantined persons, 26.1% were related to the healthcare system (hospital or clinic), and 13.3% occurred in nursing homes. As of April 30, 2020, 644 COVID­19-related deaths were registered in Poland (46.5% women). The death rate for the whole country was 1.7 per 100 000 inhabitants. CONCLUSIONS: Our data showed higher notification rate for COVID­19 among women than men, but men were more likely to die from COVID­19. The notification rate for COVID-19 in Poland among women aged 45 to 54 years was 2­fold higher than among men.

Sex differences in the frequency of gastrointestinal symptoms and olfactory or taste disorders in 1942 nonhospitalized patients with coronavirus disease 2019 (COVID-19).

INTRODUCTION: The coronavirus disease 2019 (COVID 19) is a communicable disease caused by a novel coronavirus. OBJECTIVES: This study aimed to assess self­reported frequency of gastrointestinal symptoms and olfactory or taste disorders in nonhospitalized patients with COVID­19 in Poland. PATIENTS AND METHODS: This cross­sectional survey was conducted between April 17 and 18, 2020, in 4516 nonhospitalized patients with COVID­19 in Poland. The questionnaire included 8 questions related to the health status, symptoms of COVID­19, comorbidities, and smoking status. RESULTS: Completed questionnaires were obtained from 1942 patients with COVID­19 with a response rate of 43%. The median age of the respondents was 50 years; 60.2% were women. Among nonhospitalized patients with COVID­19, 21.3% had hypertension, 4.5% had diabetes, and 3.1% had a chronic respiratory disease. Regular tobacco use was declared by 11.2% of patients with COVID­19. At least one gastrointestinal symptom was reported by 53.6% of patients. Almost half of patients (47%) with COVID­19 reported lack of appetite and 24.2% reported diarrhea. Among 1942 interviewed patients, 54.2% reported at least 1 olfactory or taste disorder and 42.5% reported both alterations. Self­reported olfactory and taste disorders were 49.2% and 47.5%, respectively. Self­reported frequency of gastrointestinal symptoms and olfactory or taste disorders during COVID­19 was significantly higher (P <0.001) in women than men. CONCLUSIONS: This study demonstrated that olfactory and taste disorders are frequent symptoms in patients with mild­to­moderate COVID­19. Moreover, our study indicated sex differences in the frequency of gastrointestinal symptoms and olfactory or taste disorders among nonhospitalized patients with COVID­19.
