Background:Osteoporosis is a major public health problem as the majority of people are not aware of the disease until the complications occur.Objective:The aims of this study were to validate Osteoporosis Knowledge Tool (OKT-A) Arabic version and to assess the osteoporosis knowledge among Iraqi general population.Methods:A descriptive, cross-sectional study was carried out in the city of Baghdad with a random cluster sampling method from the community. Forward–backward-forward translation method was used to translate the OKT questionnaire from English into Arabic language. The psychometric assessment process includes: face validity, reliability (Cronbach’s alpha and test-retest), item difficulty index, point biserial correlation and discriminatory power.Results:The results showed good face validity. The Cronbach’s alpha and Pearson correlation coefficient of the test re-test reliability were 0.775 and 0.412, respectively. Item difficulty index, point biserial correlation ranges and discriminatory power were 0.105 to 0.852, 0.105 to 0.445 and 0.933, respectively. These results demonstrated that OKT-A was a reliable and stable tool. The results showed low OKT-A scores 11.50±3.958. Furthermore, the OKT-A scores and its subscales were less than 50%. In addition, there were significant differences between the following independent variables in relation to total OKT-A scores: educational level, do you have osteoporosis or ever heard about osteoporosis. Moreover, there was a significant association between ever heard about osteoporosis groups and the OKT-A knowledge levels.Conclusion:This study showed good validity and reliability of OKT-A tool among Arabic general population. In addition, the results showed an urgent need for implementing an educational programme and should be a public health practice to increase the knowledge toward osteoporosis and its related risk factor.

Objective: The World Health Organization (WHO) Adult ADHD Self-Report Scale (ASRS) is intended to measure population prevalence of ADHD. The short version ASRS-6 has yet not been validated in a population setting. Our aim was to examine the validity of the ASRS-6 in a general population. Method: We used the Stockholm Public Health Cohort 2014. The convergent validity was assessed using item response theory (IRT). The discriminant validity was assessed by examining the correlation between the ASRS and known correlates. Results: The ASRS-6 was unidimensional albeit with hyperactivity and impulsivity items fitting less good. IRT analysis showed that the item difficulty ranged between easy to hard and that the four items on inattention had good or very good discriminatory ability. Correlates were all in the expected direction. Conclusion: The ASRS-6 has adequate validity in the general population but reflects the duality of ADHD having both inattention and hyperactivity/impulsivity as sufficient and non-necessary criteria.

Preventive Effects

There is a strong belief among the general population that sport has positive effects. However, only some preventive effects of sport meet these high expectations. Numerous studies have specifically shown that sport does not protect people from the consumption of legal and illegal drugs such as alcohol, tobacco and cannabis. For this reason, the umbrella organisation of Swiss sports associations (Swiss Olympic), the Federal Office of Sport (FOSPO) and the Federal Office of Public Health (FOPH) teamed up as early as 2003 and launched the “cool and clean” prevention programme. Over the last 14 years, it has developed into Switzerland’s largest national prevention programme and has also attracted international attention. This article summarizes how “cool and clean” works and what the programme achieved so far.

Coronavirus disease 2019 (COVID-19) has become a serious public health problem worldwide. In general, healthcare workers are considered to be at higher risk of COVID-19 infection. However, the prevalence of COVID-19 among healthcare workers in Japan is not well characterized. In this study, we aimed to examine the seroprevalence of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) antibodies among 2160 healthcare workers in hospitals and clinics that are not designated to treat COVID-19 patients in Japan. The prevalence of SARS-CoV-2 immunoglobulin G was 1.2% in August and October 2020 (during and after the second wave of the pandemic in Japan), which is relatively higher than that in the general population in Japan (0.03–0.91%). Because of the higher risk of COVID-19 infection, healthcare workers should be the top priority for further social support and vaccination against SARS-CoV-2.

Vaccine Confidence

Abstract Hesitancy is defined as the reluctance or refusal to be vaccinated even in case of vaccine availability and is included by the WHO among the top ten threats to global health. Vaccine confidence is an essential component of the hesitancy. Fear of adverse events and lack of trust in vaccine efficacy discourage the public and drive them toward the choice of refusal. Misinformation and lack of effective communication strategies may seriously jeopardize vaccination programmes. Providing effective communication requires specific competencies that often are not part of the common core competencies of those involved in vaccination programmes. In particular, the rapid evolution of the communication environment due to novel technologies makes the task even more difficult. The general population in order to comply with the official vaccine recommendation throughout the life course is therefore a complex task. In the presence of worrying signals of lack of vaccine confidence, public health decision can be driven by emergency decisions rather than investing in mid-terms communication programmes. Vaccination mandates are public health measures that are proven to be effective in increasing vaccine uptake. Increasing anti-vaccine sentiment may be a potential negative trade-off. For this reason, the introduction of vaccination mandates should be combined with a structured communication strategy. In addition, vaccine sentiment should be actively monitored when any change in vaccine offer policy is implemented.

Abstract Background Epidemiological data indicate that a large part of population needs to be vaccinated to achieve herd immunity. Hence, it is of high importance for public health officials to know whether people are going to get vaccinated for COVID-19. The objective of the present study was to examine the willingness of adult residents in Greece to receive a COVID-19 vaccine. Methods A cross-sectional was survey conducted among the adult general population of Greece between April 28, 2020 to May 03, 2020 (last week of lockdown), using a mixed methodology for data collection: Computer Assisted Telephone Interviewing (CATI) and Computer Assisted web Interviewing (CAWI). Using a sample size calculator, the target sample size was found to be around 1000 respondents. To ensure a nationally representative sample of the urban/rural population according to the Greek census 2011, a proportionate stratified by region systematic sampling procedure was used to recruit particpants. Data collection was guided through a structured questionnaire. Regarding willingness to COVID-19 vaccination, participants were asked to answer the following question: “If there was a vaccine available for the novel coronavirus, would you do it?” Results Of 1004 respondents only 57.7% stated that they are going to get vaccinated for COVID-19. Respondents aged > 65 years old, those who either themselves or a member of their household belonged to a vulnerable group, those believing that the COVID-19 virus was not developed in laboratories by humans, those believing that coronavirus is far more contagious and lethal compared to the H1N1 virus, and those believing that next waves are coming were statistically significantly more likely to be willing to get a COVID-19 vaccine. Higher knowledge score regarding symptoms, transmission routes and prevention and control measures against COVID-19 was significantly associated with higher willingness of respondents to get vaccinated. Conclusion A significant proportion of individuals in the general population are unwilling to receive a COVID-19 vaccine, stressing the need for public health officials to take immediate awareness-raising measures.

After the bioterrorism-anthrax attacks of 2001, individual public health officials were tasked with planning population-wide medicine dispensing. This planning started with assumptions and then evaluations of seasonal immunization clinics. Research of the 2009 H1N1 pandemic-vaccination campaign showed that an adequately prepared public health system could have prevented over 16% of flu-associated hospitalizations. The 2011 ice storms revealed difficulties with sheltering medically fragile persons with disabilities. Later research showed that training and preparedness levels increased responders’ willingness to serve. Also, when triaging disaster survivors to general shelters, medical shelters, or mental health services; sorting to community mass care services improved up to 15% when past traumatic effects, personal care assistance, or service methodology were accounted for. The number of persons who are disabled and dependent on electric medical equipment are increasing. This current study compared the time it takes to dispense medication to two different cohorts: a general-population cohort (n=31) and a special-needs cohort (n=30). The cohort comprised entirely of persons with special needs took 4.1 compared to 2.48 minutes per person in a general population cohort (p=.057). A person with any special needs took 3.73 versus 2.43 minutes for a person with no special needs (p=.082). Modeling of service times per station and cohort type found significant delays at the medical station among persons in the general population who are pregnant (840 seconds, p=.002) and persons in the special needs cohort with a language barrier (750 seconds, p=.001).
