Fact Checking

Background: Delaying doctor consultation is harmful. Fear of COVID-19 leads to delays in seeking medical care at a time when pandemic information overflows. However, little is known about the role of COVID-19 related fear, attention to information, and fact-checking in such delay.Objective: Under the Hong Kong Jockey Club SMART Family-Link Project, we examined the associations of delay in doctor consultation amidst the pandemic with sociodemographic characteristics, COVID-19 related fear, attention to information, and fact-checking.Methods: We conducted a population-based online cross-sectional survey in May 2020 on Hong Kong Chinese adults. Respondents reported whether the pandemic caused any delay in doctor consultation (yes/no), level of COVID-19 related fear, attention to information and fact-checking (all on a scale of 0 to 10 and recoded into tertiles of low, moderate, high). Regression analyses were used to examine the associations of delay and fear with sociodemographic characteristics, attention and fact-checking, adjusting for covariates. Data were weighted by sex, age and education level of the population.Results: Of 4,551 respondents (46.5% male, 59.7% aged over 45 years), 10.1% reported delay in doctor consultation. The mean score was 6.4 for fear, 8.0 for attention and 7.4 for fact-checking. Delay was more common in males and increased with age and fear. High vs. low level of fear was associated with delay [adjusted odd ratios (AOR) 2.68, 95% confidence interval (CI) 2.08, 3.47]. Moderate level of fact-checking was negatively associated with delay (AOR 1.28, 95% CI 0.98, 1.67). Females reported greater fear and fear decreased with age. Fear increased with attention to information and decreased with fact-checking. Fear substantially mediated the association of delay with attention (96%) and fact-checking (30%).Conclusions: We have first shown that delay in doctor consultation increased with fear of COVID-19 and decreased with fact-checking amidst the pandemic. Fear also increased with attention to COVID-19 related information and decreased with fact-checking. Understanding these associations can help policymakers develop targeted communication and support to the public to reduce delayed doctor consultations and the associated COVID-19-related or unrelated morbidity and mortality in the community.

Vaccination is one of the most effective ways to stop the spread of COVID-19. Understanding factors associated with intention to receive COVID-19 vaccines is the key to a successful vaccination programme. This cross-sectional study explored the rate of vaccination intention and identified its predictors using the health belief model (HBM) in the general population in Hong Kong during the pandemic. Data were collected between December 2020 and January 2021 via telephone surveys. Hierarchical logistic regression analysis was used to identify factors associated with intention to receive COVID-19 vaccines. A total of 1255 adults (>18 years, 53% female) completed the telephone survey. Overall, 42% indicated an intention to vaccinate, 31.5% showed vaccine hesitancy, and 26.5% reported refusal to receive any COVID-19 vaccines. Individuals who were men, older in age, working, with past experiences of other pandemics, less concerned with the vaccine safety, with poorer knowledge about COVID-19, and having greater levels of perceived susceptibility, self-efficacy, cues to action, and acceptance of governmental preventive measures related to COVID-19 were significantly more likely to report an intention to vaccinate. The low intention among the Hong Kong population reflects the importance of developing effective vaccination promotion campaigns with the predictors identified in this study.

Purpose. To assess the prevalence of each step in the smoking-cessation process (intention to quit, attempts to quit, and successful quitting) and to examine the factors associated with them among Chinese smokers. Design. A cross-sectional survey of subjects from randomly selected households. Setting. Four thousand one hundred forty-two households in Hong Kong. Subjects. A total of 11,779 persons, aged 15 years or older, were enumerated (response rate = 74.0%). Measures. A validated structured questionnaire was used for data collection. The questionnaire sought information on the subject's sociodemographic background, smoking habits, and workplace attitude to smoking. The predictors for successful quitting, past quitting attempts, and intention to quit were assessed by χ2 tests and multiple logistic regression. Results. Of the respondents, 14.4% were current smokers, 7.5% were ex-smokers, and 78.1% were nonsmokers. Of the daily smokers, 52% intended to quit. The factors associated with quitting were being married, being in the student/retired/others category, being older, having received higher education, not smoking to kill time, and smoking because of curiosity. Being married and not smoking to kill time were associated with past quitting attempts. Being male, married, and not smoking to kill time were associated with the intention to quit smoking. Conclusion. The findings of this study indicate that differing predictors may contribute to the different transitional stages of smoking cessation. Population-based smoking-cessation programs should take these predictors into consideration in the design of interventions.

ObjectivesTo determine the prevalence of diabetes mellitus (DM), prevalence of diabetic retinopathy (DR) and sight-threatening conditions among persons with DM aged 50 years and older in Sohag governorate in Upper Egypt.DesignPopulation-based, cross-sectional survey using the standardised Rapid Assessment of Avoidable Blindness with the addition of the Diabetic Retinopathy module methodology.SettingsSohag governorate in Egypt where 68 clusters were selected using probability proportional to population size. Households were selected using the compact segment technique.Participants4078 people aged 50 years and older in 68 clusters were enrolled, of which 4033 participants had their random blood sugar checked and 843 examined for features of DR.Primary and secondary outcomesThe prevalence of DM and DR; secondary outcome was the coverage with diabetic eye care.ResultsThe prevalence of DM was 20.9% (95% CI 19.3% to 22.5%). The prevalence in females (23.8%; 95% CI 21.4% to 26.3%) was significantly higher than in males (18.9%; 95% CI 17.1% to 20.7%) (p=0.0001). Only 38.8% of persons diagnosed with diabetes had good control of DM. The prevalence of DR in the sample was 17.9% (95% CI 14.7% to 21.1%). The prevalence in females was higher (18.9%; 95% CI 14.0% to 23.8%) than in males (17.1%; 95% CI 13.0% to 21.2%). Up to 85.3% of study participants have never had eye examination. Sight-threatening DR (R4 and/or M2) was detected in 5.2% (95% CI 3.4% to 7.0%) with only 2.3% having had laser treatment.ConclusionThe prevalence of uncontrolled DM in Sohag governorate in Egypt is higher than the national prevalence. There is a high prevalence of sight-threatening retinopathy and/or maculopathy with few people having access to diabetic eye care. A public health approach is needed for health promotion, early detection and management of DR.

Plasmodium Vivax Malaria

The measurement of recent malaria exposure can support malaria control efforts. This study evaluated serological responses to an in-house Plasmodium vivax Merozoite Surface Protein 8 (PvMSP8) expressed in a Baculovirus system as sero-marker of recent exposure to P. vivax (Pv) in the Peruvian Amazon. In a first evaluation, IgGs against PvMSP8 and PvMSP10 proteins were measured by Luminex in a cohort of 422 Amazonian individuals with known history of Pv exposure (monthly data of infection status by qPCR and/or microscopy over five months). Both serological responses were able to discriminate between exposed and non-exposed individuals in a good manner, with slightly higher performance of anti-PvMSP10 IgGs (area under the curve AUC = 0.78 [95% CI = 0.72–0.83]) than anti-PvMSP8 IgGs (AUC = 0.72 [95% CI = 0.67–0.78]) (p = 0.01). In a second evaluation, the analysis by ELISA of 1251 plasma samples, collected during a population-based cross-sectional survey, confirmed the good performance of anti-PvMSP8 IgGs for discriminating between individuals with Pv infection at the time of survey and/or with antecedent of Pv in the past month (AUC = 0.79 [95% CI = 0.74–0.83]). Anti-PvMSP8 IgG antibodies can be considered as a good biomarker of recent Pv exposure in low-moderate transmission settings of the Peruvian Amazon.
