Vaccine 2022; 40:7238-7246. [PMID: 36328882 DOI: 10.1016/j.vaccine.2022.08.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Revised: 07/13/2022] [Accepted: 08/08/2022] [Indexed: 11/11/2022]
Abstract
BACKGROUND/AIM Influenza vaccination is strongly recommended every year for aged care staff to protect themselves and minimise risk of transmission to residents. This study aimed to determine the factors associated with repeated annual influenza vaccine uptake among Australian aged care staff from 2017 to 2019. METHODS Demographic, medical and vaccination data collected from the staff, who participated in an observational study from nine aged care facilities under a single provider in Sydney Australia, were analysed retrospectively. Based on the pattern of repeated influenza vaccination from 2017 to 2019, three groups were identified: (1) unvaccinated all three years; (2) vaccinated occasionally(once or twice) over three years; and (3)vaccinated all threeyears. Multinomial logistic regression analysis was performed to better understand the factors associated with the pattern of repeated influenza vaccination. RESULTS From a total of 138 staff, between 2017 and 2019, 28.9 % (n = 40) never had a vaccination, while 44.2 % (n = 61) had vaccination occasionally and 26.8 % (n = 37) had vaccination all three years. In the multinomial logistic regression model, those who were<40 years old (OR = 0.57, 95 % CI: 0.19-0.90, p < 0.05) and those who were current smokers (OR = 0.20; 95 % CI: 0.03-0.76, p < 0.05) were less likely to have repeated vaccination for all three years compared to the unvaccinated group. Those who were<40 years old (OR = 0.61; 95 % CI: 0.22-0.68, p < 0.05) and those who were born overseas (OR = 0.50; 95 % CI:0.27-0.69, p < 0.05) were more likely to be vaccinated occasionally compared to the unvaccinated group. CONCLUSION The significant predictors of repeated vaccine uptake across the three-year study period among aged care staff were age, smoking status and country of birth (Other vs Australia). Targeted interventions towards the younger age group (<40 years old), smokers and those who were born overseas could improve repeated influenza vaccination uptake in the aged care workforce.

J Family Community Med 2022; 29:238-253. [PMID: 36389030 PMCID: PMC9664465 DOI: 10.4103/jfcm.jfcm_119_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2022] [Revised: 07/04/2022] [Accepted: 07/19/2022] [Indexed: 06/16/2023] Open
Abstract
BACKGROUND The most cost-effective measure for preventing the infectious disease, influenza, is vaccination. The purpose of this research was to evaluate knowledge levels, familiarity, and attitude toward influenza and influenza vaccination of the Riyadh adult population. MATERIALS AND METHODS A cross-sectional study was carried out in Riyadh and data was collected between December 2017 and March 2018. Five hundred participants were interviewed in person using a closed-ended questionnaire. Participants comprised the general population, students, and healthcare workers (HCWs), and were recruited from shopping malls, parks, Princess Nourah Bint Abdulrahman University, and King Abdullah Bin Abdulaziz University Hospital. A pilot study was conducted among 15 participants from the general population, students, and HCWs who gave verbal consent. Participants were asked if they comprehended the questionnaire and whether they felt comfortable participating. Descriptive statistics were used to describe the sample. Statistical significance was determined using t-test for quantitative variables and Chi-square test for qualitative variables. RESULTS Most participants in all groups had poor knowledge. The least informed was the general population (8.8%), followed by the students (11.8%), and the most aware were the HCWs (18.5%). The social media (35%) was the main source of participants' knowledge, followed by doctors and health educators in hospitals (33%). Only 15.6% of participants had been vaccinated this year. Even fewer (8.8%) stated that they took the vaccination every year. The most important reasons for getting vaccinated were the recommendations by the Ministry of Health or by their doctors (77.8% for each). The key barrier to vaccination was a lack of perceived benefit (the participants did not usually get influenza so they felt vaccination was unnecessary [66.2%]). About 34% of participants reported that they had the children in their families vaccinated. The main reason given was to protect their children from influenza complications (80.6%). CONCLUSION Within the Riyadh adult population, there was both low compliance to take the influenza vaccinations owing to a lack of perceived benefit and insufficient knowledge of the risks of influenza.

Abstract
BACKGROUND Older adults with chronic conditions are at high risk of complications from influenza and pneumococcal infections. Evidence about factors associated with influenza and pneumococcal vaccination among older multimorbid persons in Europe is limited. The aim of this study was to investigate the prevalence and determinants of these vaccinations in this population. METHODS Multimorbid patients aged ≥70 years with polypharmacy were enrolled in 4 European centers in Switzerland, Belgium, the Netherlands, and Ireland. Data on vaccinations, demographics, health care contacts, and comorbidities were obtained from self-report, general practitioners and medical records. The association of comorbidities or medical contacts with vaccination status was assessed using multivariable adjusted log-binomial regression models. RESULTS Among 1956 participants with available influenza vaccination data (median age 79 years, 45% women), 1314 (67%) received an influenza vaccination within the last year. Of 1400 patients with available pneumococcal vaccination data (median age 79 years, 46% women), prevalence of pneumococcal vaccination was 21% (n = 291). The prevalence of vaccination remained low in high-risk populations with chronic respiratory disease (34%) or diabetes (24%), but increased with an increasing number of outpatient medical contacts. Chronic respiratory disease was independently associated with the receipt of both influenza and pneumococcal vaccinations (prevalence ratio [PR] 1.09, 95% confidence interval [CI] 1.03-1.16; and PR 2.03, 95%CI 1.22-3.40, respectively), as was diabetes (PR 1.06, 95%CI 1.03-1.08; PR 1.24, 95%CI 1.16-1.34, respectively). An independent association was found between number of general practitioner visits and higher prevalence of pneumococcal vaccination (p for linear trend <0.001). CONCLUSION Uptake of influenza and particularly of pneumococcal vaccination in this population of European multimorbid older inpatients remains insufficient and is determined by comorbidities and number and type of health care contacts, especially outpatient medical visits. Hospitalization may be an opportunity to promote vaccination, particularly targeting patients with few outpatient physician contacts.

Abstract
Immunosenescence and comorbidities increase the susceptibility of older adults with diabetes mellitus (DM) to vaccine-preventable diseases, hospitalization, disability, or death. This systematic review synthesizes research on protecting older adults with DM during pandemics, exploring vaccine safety, tolerance, and vaccination uptake by older adults in anticipation of seasonal influenza outbreaks during the current COVID-19 threat. Addressed were: (a) age-related factors influencing the effectiveness of vaccines against infectious disease in older adults; (b) vaccine safety, tolerance, effectiveness for older persons with DM; and (c) issues affecting older adults accepting immunization recommendations. Medline and CINAHL databases yielded 214 studies with 43 meeting inclusion criteria (32 descriptive and 11 controlled trials). Findings show altered glycemic control stimulates proinflammatory mediators, increasing infection risk, vaccines, and annual revaccinations safely reduce hospitalization rates, mortality outcomes, without affecting glycemic control. However, vaccines fail to evoke optimal antibody responses in older adults. Unawareness, fear of side effects, tend to lower vaccination participation.

Abstract
Introduction In the past few decades, patients expressing the idea that vaccines are unsafe or unneeded have been experienced increasingly by physicians and other healthcare providers. Discussions with patients regarding their reasons for vaccine refusals are important, as it may provide information that can be utilized in an intervention to increase vaccination rates and combat the spread of diseases that are making a resurgence in the United States. The main objective of this study was to explore the perceptions of family physicians as to why parents in Kansas may be vaccine hesitant. Methods An electronic survey was distributed to family physicians in the State of Kansas via the University of Kansas School of Medicine-Wichita Family Medicine Research and Data Information Office (FM RADIO). Several aspects of physician perceptions regarding patients’ vaccine hesitancy were measured in this study, including vaccines that are most often refused, reasons for refusing vaccinations, as well as what responses physicians employ when presented with vaccine concerns. Results The majority of physicians surveyed have experienced vaccine hesitancy or refusal in their practice, and the human papillomavirus (HPV) and flu vaccines were reported to be the primary vaccines refused for children. In addition, physicians reported frequently employing various practices in response to vaccine refusals, including requiring parents to sign a form (40%) and dismissing families from their practice (1.5%). Physician perceptions on the reasons as to why parents/guardians refuse vaccinations also were measured, and the most common response was that parents possess a fear of long-term complications for their children as a result of vaccines (74%). Additionally, the three most commonly refused vaccines were HPV, influenza, and measles, mumps, and rubella. Conclusion Physicians must not only deal with time constraints that vaccine hesitant discussions require, but also must try and implement discussions or interventions suited to the varying reasons why parents/guardians refuse vaccines to convince parents of their safety. The results suggested that vaccine refusals by parents/guardians seemed to be affecting Kansas family physicians’ clinics in more than one way. This study could be a useful tool to help physicians better understand why vaccine refusals occur and be able to combat unwarranted concerns about vaccines.

Abstract
Background Based on current evidence, vaccination is recommended against the influenza virus and pneumococcus to avoid serious acute exacerbations in patients with chronic obstructive pulmonary disease (COPD), but the rate of their vaccination coverage is still suboptimal. To determine the prevalence and effectiveness of influenza and pneumococcal vaccination in COPD patients, and to prove its hypothetical association with the decreasing number of acute exacerbations. Methods We conducted a retrospective, population-based cohort study. Influenza and pneumococcal vaccination history were collected from 250 patients selected by simple random sampling from all COPD patients in Budapest at the Department of Pulmonary Rehabilitation of the National Koranyi Institute of Pulmonology between 01 January 2019 and 01 June 2019. Inclusion criteria were the following: age 40 years and diagnosis of COPD. Odds ratios (ORs) were evaluated based on the occurrence of acute exacerbations during the preceding year. Results The average age was 66.62 (±8.34) years, 67.30 (±8.54) for males, and 66.09 (±8.16) for females. Man:woman ratio: 43.6%:56.4% in total. Overall prevalence of influenza vaccination was 23.6%, and the pneumococcal vaccination rate was 10.8% among COPD patients. Influenza and pneumococcal vaccination showed a significant protective effect and reduced the occurrence of exacerbations in the following year, influenza vaccination OR: 2.11 (95% CI: 0.88-5.02), pneumococcal vaccination OR: 1.06 (95% CI: 0.84-1.34), when taking both vaccination: OR: 2.37 (95% CI: 1.39-4.08). Conclusions We found association between influenza and pneumococcal vaccination and the reduced risk of hospitalization due to exacerbations in the ensuing year. The prevalence of vaccination is significantly below the optimal level.

Abstract
BACKGROUND Influenza viral infection is a major public health problem with significant morbidity and mortality.Asthma is a risk factor for developing serious complications related to influenza infection. OBJECTIVE We explored factors associated with influenza vaccination coverage among adolescents with asthma. METHODS Data were obtained from 62,276 participants in the 13th Korean Youth Risk Behavior Web-Based Survey (KYRBS) conducted in 2017. KYRBS data were obtained from a stratified, multistage, clustered sample. We used multiple logistic regression analyses to identify variables potentially related to influenza vaccination in adolescents with asthma. RESULTS The proportion of asthma was 8.8%, and the influenza vaccination rate overall was 37.9%. It was 41.8% in the asthma group and 37.5% in the nonasthma group (p < 0.001). After regression, male sex (odds ratio (OR) = 1.45; 95% CI 1.35-1.55), a high socioeconomic status (OR = 1.12; 95% CI 1.05-1.19), residence at an orphanage (OR = 1.93; 95% CI 1.38-2.29), regular breakfast consumption (OR = 1.09; 95% CI 1.02-1.17), and subjective good health (OR = 2.39; 95% CI 1.69-3.39) were associated with increased influenza vaccination, whereas current smoking (OR = 0.87; 95% CI 0.67-0.96) and a depressive mood (OR = 0.77; 95% CI 0.64-0.95) were inversely associated in adolescents with asthma. CONCLUSION It is important to improve influenza vaccination in adolescents with asthma, especially females, those with a low socioeconomic status, independent residents, breakfast skippers, current smokers, and those who consider themselves unhealthy and have depressive moods.

Abstract
INTRODUCTION Influenza vaccination is the most effective way to prevent influenza. Few studies on its rate were reported throughout China and for populations with chronic diseases. An estimation of the rates in China was accomplished. METHODS All data were from a national cross-sectional survey of a sample representing the population aged 40 years or older in mainland China in 2014-15. A total of 74,484 individuals with complete self-reported influenza vaccination status were analyzed in 2018-19. RESULTS The overall influenza vaccination rate was 2.4% (95% CI 1.4-3.3) with 1.7% (95% CI 1.2-2.2) for the age group 40-59 years and 3.8% (95% CI 1.6-5.9) for the group ≥60 years. The rate was 4.0% (95% CI 2.0-5.9) among people with a chronic disease. People with asthma and people with emphysema had the highest rates (7.1%, 95% CI 3.2-11.0 and 6.6%, 95% CI 3.6-9.7) while people with chronic obstructive pulmonary disease (COPD) and people with chronic bronchitis had the lower rates (3.6%, 95% CI 2.0-5.2 and 4.8%, 95% CI 2.6-7.0). The rate was the highest among former smokers (3.3%, 95% CI 2.3-4.4) compared to current smokers (1.8%, 95% CI 0.9-2.7) and never smokers (2.5%, 95% CI 1.4-3.6). People living with finance-reimbursed vaccination policy, a positive factor for vaccination, had a higher vaccination rate (11.5%, 95% CI 10.8-12.2) (p < 0.05). People with older age, higher education level, occupation of professionals or technical personnel, living in rural areas or Northern China, former/never smoking were more likely to be vaccinated (p < 0.05). CONCLUSIONS The influenza vaccination rate is low among adults aged ≥40 years, those ≥60 years and those with chronic diseases in China. Reimbursement policy targeting the elderly should be implemented widely and strategies towards patients with chronic diseases need urgent attention to increase the influenza vaccination coverage.

Despite 79,400 deaths due to the influenza (flu) virus during the 2017-18 season, <50% of US adults receive an annual flu vaccination (AFV). Self-rated health status (SRH) is associated with health behavior utilization. The current study aims to determine if an association exists between an individual's SRH and their receipt of an AFV. In the 2017 US Behavioral Risk Factor Surveillance System survey, 39.1% of respondents had received a flu vaccination within the last 12 months. There was a statistically significant difference (p < 0.0001) between the vaccination rates of men (35.7%) and women (42.4%). There was a significant positive association between SRH and AFV for individuals who self-reported an SRH of either "Fair" (AOR 1.19; 95% CI 1.12-1.27) or "Poor" (AOR 1.24; 95% CI 1.14-1.35), compared to those reporting a status of "Excellent". For those reporting an SRH status of "Fair", there was a significant positive association for both men (AOR 1.20; 95% CI 1.10-1.32) and women (AOR 1.17; 95% CI 1.08-1.28). An association was also found for men (AOR 1.203; 95% CI 1.09-1.39) and women (AOR 1.23; 95% CI 1.09-1.399) who reported their SRH as "Poor". Only women showed a significant association (AOR 1.12; 95% CI 1.04-1.20) among those whose SRH was "Good". No association was found for individuals who reported SRH as "Very Good". These findings are of interest to health policy makers as they show there is still work required to convince individuals with a high SRH that they too need to receive an AFV.

Factors Associated with Antenatal Influenza Vaccination in a Medically Underserved Population. Infect Dis Obstet Gynecol 2020; 2020:5803926. [PMID: 32410818 PMCID: PMC7204164 DOI: 10.1155/2020/5803926] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2019] [Accepted: 12/04/2019] [Indexed: 02/02/2023] Open
Abstract
Influenza infection in pregnant women is associated with increased risk of morbidity and mortality. Despite recommendations for all women to receive the seasonal influenza vaccine during pregnancy, vaccination rates among pregnant women in the U.S. have remained around 50%. The objective of this study was to evaluate clinical and demographic factors associated with antenatal influenza vaccination in a medically underserved population of women. We conducted a retrospective cohort study at Grady Memorial Hospital, a large safety-net hospital in Atlanta, Georgia, from July 1, 2016, to June 30, 2018. Demographic and clinical characteristics were abstracted from the electronic medical record. The Kotelchuck index was used to assess prenatal care adequacy. Relative risks and 95% confidence intervals for associations between receipt of influenza vaccine and prenatal care adequacy, demographic characteristics, and clinical characteristics were calculated using multivariable log-binominal models. Among 3723 pregnant women with deliveries, women were primarily non-Hispanic black (68.4%) and had Medicaid as their primary insurance type (87.9%). The overall vaccination rate was 49.8% (1853/3723). Inadequate prenatal care adequacy was associated with a lower antenatal influenza vaccination rate (43.5%), while intermediate and higher levels of prenatal care adequacy were associated with higher vaccination rates (66.9–68.3%). Hispanic ethnicity, non-Hispanic other race/ethnicity, interpreter use for a language other than Spanish, and preexisting diabetes mellitus were associated with higher vaccination coverage in multivariable analyses. Among medically underserved pregnant women, inadequate prenatal care utilization was associated with a lower rate of antenatal influenza vaccination. Socially disadvantaged women may face individual and structural barriers when accessing prenatal care, suggesting that evidenced-based, tailored approaches may be needed to improve prenatal care utilization and antenatal influenza vaccination rates.

Tokars JI, Olsen SJ, Reed C. Seasonal Incidence of Symptomatic Influenza in the United States. Clin Infect Dis 2019; 66:1511-1518. [PMID: 29206909 DOI: 10.1093/cid/cix1060] [Citation(s) in RCA: 163] [Impact Index Per Article: 32.6] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2017] [Accepted: 11/29/2017] [Indexed: 02/02/2023] Open
Abstract
Background The seasonal incidence of influenza is often approximated as 5%-20%. Methods We used 2 methods to estimate the seasonal incidence of symptomatic influenza in the United States. First, we made a statistical estimate extrapolated from influenza-associated hospitalization rates for 2010-2011 to 2015-2016, collected as part of national surveillance, covering approximately 9% of the United States, and including the existing mix of vaccinated and unvaccinated persons. Second, we performed a literature search and meta-analysis of published manuscripts that followed cohorts of subjects during 1996-2016 to detect laboratory-confirmed symptomatic influenza among unvaccinated persons; we adjusted this result to the US median vaccination coverage and effectiveness during 2010-2016. Results The statistical estimate of influenza incidence among all ages ranged from 3.0%-11.3% among seasons, with median values of 8.3% (95% confidence interval [CI], 7.3%-9.7%) for all ages, 9.3% (95% CI, 8.2%-11.1%) for children <18 years, and 8.9% (95% CI, 8.2%-9.9%) for adults 18-64 years. Corresponding values for the meta-analysis were 7.1% (95% CI, 6.1%-8.1%) for all ages, 8.7% (95% CI, 6.6%-10.5%) for children, and 5.1% (95% CI, 3.6%-6.6%) for adults. Conclusions The 2 approaches produced comparable results for children and persons of all ages. The statistical estimates are more versatile and permit estimation of season-to-season variation. During 2010-2016, the incidence of symptomatic influenza among vaccinated and unvaccinated US residents, including both medically attended and nonattended infections, was approximately 8% and varied from 3% to 11% among seasons.

Abstract
This study aimed to estimate the prevalence of influenza vaccination in elderly Brazilians with specific chronic diseases. The sample included individuals 60 years or older (n = 23,815) participating in the National Health Survey (PNS) in 2013. The study estimated the prevalence rates for influenza vaccination and the respective 95% confidence intervals (95%CI). The associations were verified with the chi-square test (Rao-Scott) with 5% significance. Prevalence of influenza vaccination in the elderly was 73.1% (95%CI: 72.0-74.1), and there was no significant difference in prevalence rates between men and women (p = 0.237). Statistically significant differences were observed in prevalence rates for elderly that reported arterial hypertension, 75% (p < 0.001), diabetes mellitus, 76.5% (p = 0.009), cardiac disease, 79.2% (p < 0.001), and lung disease or chronic obstructive pulmonary disease (COPD), 87% (p = 0.001). The results showed low prevalence of vaccination in elderly with some specific chronic diseases for whom there is formal recommendation to receive the vaccine, suggesting the need for a vaccination campaign to extrapolate the age cutoff (elderly) and better targeting to these specific subgroups.

Abstract
OBJECTIVE: The purpose of this study is to detect the prevalence and the factors associated with influenza and pneumococcal vaccination and outcomes of vaccination during 2013–2014 season in patients with chronic obstructive pulmonary disease (COPD) in Turkey. METHODS: This was a multicenter retrospective cohort study performed in 53 different centers in Turkey. RESULTS: During the study period, 4968 patients were included. COPD was staged as GOLD 1-2-3-4 in 9.0%, 42.8%, 35.0%, and 13.2% of the patients, respectively. Influenza vaccination rate in the previous year was 37.9%; and pneumococcus vaccination rate, at least once during in a life time, was 13.3%. Patients with older age, higher level of education, more severe COPD, and comorbidities, ex-smokers, and patients residing in urban areas had higher rates of influenza vaccination. Multivariate logistic regression analysis showed that advanced age, higher education levels, presence of comorbidities, higher COPD stages, and exacerbation rates were associated with both influenza and pneumococcal vaccination. The number of annual physician/outpatient visits and hospitalizations due to COPD exacerbation was 2.73 ± 2.85 and 0.92 ± 1.58 per year, respectively. Patients with older age, lower education levels, more severe COPD, comorbid diseases, and lower body mass index and patients who are male and are residing in rural areas and vaccinated for influenza had significantly higher rates of COPD exacerbation. CONCLUSIONS: The rates of influenza and pneumococcal vaccination in COPD patients were quite low, and the number of annual physician/outpatient visits and hospitalizations due to COPD exacerbation was high in Turkey. Advanced age, higher education levels, comorbidities, and higher COPD stages were associated with both influenza and pneumococcal vaccination.

Abstract
OBJECTIVE To examine the association of genotype with smoking and other key health behaviors among individuals with alpha-1 antitrypsin deficiency (AATD) associated lung disease. METHODS Self-reported data were analyzed from 3506 individuals with AATD-associated lung disease. All data were collected upon enrollment in a disease management program designed for individuals who have been prescribed augmentation therapy. Multivariate logistic regression was utilized to examine the extent to which genotype was associated with smoking and other key health behaviors (i.e., getting a pneumonia vaccine, getting a flu vaccine, exercising, and maintaining a healthy weight). We hypothesized that MZs and SZs are more likely than ZZs to be current smokers, and that genotype is associated with additional health behaviors. RESULTS MZs and SZs had higher odds of being a current smoker than ZZs (MZ versus ZZ OR = 2.73, p < .001; SZ versus ZZ OR = 4.34, p < .001). For every additional health behavior examined, MZs had higher odds of unhealthy behavior than ZZs (ORs ranged from 1.35 to 1.98, p < .05). SZs had higher odds of unhealthy behavior than ZZs with regard to lack of exercise (OR = 1.52, p = .003) and failure to maintain a healthy weight (underweight OR = 1.93, p = .028; overweight OR = 1.43, p = .015). CONCLUSIONS Among individuals who have been prescribed augmentation therapy for lung disease due to AATD, genotype is associated with smoking and additional health behaviors that are central to managing lung disease.

Abstract
OBJECTIVES Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are major components of COPD-related socioeconomic burden. Upper or lower respiratory tract infections, usually caused by respiratory viruses or bacteria, are common causes of AECOPD. Vaccination aganist influenza virus and Streptoccus pneumoniae, the most prevalent agents, is recommended by COPD guidelines. The aims of this study were to determine the factors affecting vaccination among patients with COPD and to assess the effect of vaccination status on AECOPD. MATERIALS AND METHODS Patients with COPD were recruited from the outpatient clinic of a tertiary hospital between December 2014 and January 2015. Demographic data, vaccination status, and COPD-related hospital admissions triggered by tracheobronchial infections were evaluated. RESULTS In total, 108 patients were enrolled; 102 (94%) subjects were male, and 6 (6%) subjects were female; the mean age was 65.6 years. The number of patients who had received pneumococcal and influenza vaccinations were 8 (0.07%) and 36 (33.3%), respectively. There was no significant correlation between the level of education and vaccination status. No significant difference was found between two groups in terms of exacerbation frequency, hospitalization rates, mMRC scores, and COPD stages. CONCLUSION More efforts by both physicians and patients are needed to reach the ideal rates of vaccination for COPD.

Abstract
Despite the significant role of seasonal influenza vaccination in preventing and minimizing the serious complications of influenza infection in type 2 diabetes mellitus (T2DM) patients, unsatisfactory compliance still exists for vaccination. Study objectives were to explore the vaccination status and determinants in T2DM patients in southwestern Saudi Arabia. A cross-sectional study on a representative sample of T2DM patients in Abha city, southwestern Saudi Arabia, was conducted. Data for sociodemographic characteristics, clinical criteria, vaccination status, vaccination motivators and barriers and seasonal influenza knowledge were collected. Out of 353 T2DM patients included in the study, seasonal influenza vaccination coverage was 61% in year 2017. A significant factors associated with non-vaccination were; poor influenza and its vaccine knowledge (OR = 4.31, 95% CI: 2.73⁻6.80), illiteracy (OR = 1.93, 95% CI: 1.11⁻3.37), and more than 10 years disease duration (OR = 2.07, 95% CI: 1.11⁻3.87). Presence of family history of DM and ischemic heart comorbidity minimized the possibility of non-vaccination (OR = 0.54 and 0.28 respectively). Healthcare givers’ advice was the most reported vaccination motivator (84.7%) while; fear of vaccine side effects was the most stated barrier (73%). In conclusion, influenza vaccination rate among T2DM in the present study is less than the recommended level. Continuous primary health care center-based educational programs should be implemented to aware and encourage influenza vaccination among T2DM patients.

Abstract
OBJECTIVE Patients with chronic conditions have higher rates of severe influenza-related illness and mortality. However, influenza vaccination coverage in high-risk populations continues to be suboptimal. We describe the association between cumulative disease morbidity, measured by a previously validated multimorbidity index, and influenza vaccination among community-dwelling adults. METHODS We obtained interview and medical record data for participants ≥18 years who sought outpatient care for influenza-like illness between 2011 and 2016 as part of an outpatient-based study of influenza vaccine effectiveness. We defined cumulative disease morbidity by using medical diagnosis codes to calculate a multimorbidity-weighted index (MWI) for each participant. MWI and influenza vaccination status was evaluated by logistic regression. Akaike information criterion was calculated for all models. RESULTS Overall, 1458 (48%) of participants out of a total of 3033 received influenza vaccination. The median MWI was 0.9 (IQR 0.00-3.5) and was higher among vaccinated participants (median 1.6 versus 0.0; p < 0.001). We found a positive linear association between MWI and vaccination, and vaccination percentages were compared between categories of MWI. Compared to patients with no multimorbidity (MWI = 0), odds of vaccination were 17% higher in the second category (MWI 0.01-1.50; [OR: 1.17, 95% CI: 0.92-1.50]), 58% higher in the third category (MWI 1.51-3.00; [OR: 1.58, 95% CI: 1.26-1.99]), 130% higher in the fourth category (MWI 3.01-6.00; [OR: 2.30, 95% CI: 1.78-2.98]) and 214% higher in the fifth category (MWI 6.01-45.00;[OR: 3.14, 95% CI: 2.41-4.10]). Participants defined as high-risk had 86% greater odds of being vaccinated than non-high-risk individuals (OR: 1.86, 95% CI: 1.56-2.21). The AIC was lowest for MWI compared with high-risk conditions. CONCLUSIONS Our results suggest a dose response relationship between level of multimorbidity and likelihood of influenza vaccination. Compared with high-risk condition designations, MWI provided improved precision and a better model fit for the measurement of chronic disease and influenza vaccination.

Abstract
PURPOSE An increasing percentage of children are born to couples who cohabit but are not legally married. Using data from a nationally representative Canadian sample, we estimated associations of maternal marital and cohabitation status with stillbirth, infant mortality, preterm birth (PTB), and small- and large-for-gestational-age (SGA and LGA) birth. METHODS The 2006 Canadian Birth-Census Cohort was created by linking birth registration data with the 2006 long-form census. We used log-binomial regression to estimate risk ratios (RRs) for adverse birth outcomes associated with being single or living with a common-law partner. Analyses were adjusted for maternal age and education. RESULTS Data were analyzed for 130,931 singleton births. Adjusted RRs (95% confidence intervals) for single mothers compared with married mothers were 1.92 (1.51-2.42) for stillbirth, 2.08 (1.55-2.81) for infant mortality, 1.36 (1.27-1.46) for PTB, 1.31 (1.22-1.39) for SGA birth, and 0.95 (0.90-1.01) for LGA birth. Adjusted RRs for cohabiting mothers compared with married mothers were 0.93 (0.74-1.16) for stillbirth, 1.05 (0.81-1.35) for infant mortality, 1.09 (1.03-1.15) for PTB, 1.05 (0.99-1.10) for SGA birth, and 0.96 (0.92-1.00) for LGA birth. CONCLUSIONS In a nationally representative Canadian birth cohort, cohabiting and legally married women experienced similar birth outcomes, but most outcomes for single women were substantially worse.

Abstract
Seasonal influenza epidemics remain a considerable burden in adults, especially in those at higher risk of complications. The aim of this study was to determine the costs associated with influenza-related hospitalization in patients aged ≥65 y admitted to 20 hospitals from 7 Spanish regions during the 2013-14 and 2014-15 influenza seasons. Bivariate analysis was used to compare costs in vaccinated and unvaccinated cases. Costs were calculated according to the Spanish National Health System diagnosis-related group tables for influenza and other respiratory system conditions (GRD 89 and GRD 101). A total of 728 confirmed influenza cases were recorded: 52.9% were male, 46.7% were aged 75-84 years, and 49.3% received influenza vaccine ≥15 d prior to hospital admission. Influenza-related mean hospitalization costs (MHC) were € 1,184,808 in unvaccinated and € 1,152,333 in vaccinated cases (2.75% lower). Influenza vaccination showed significant protection against ICU admission (OR 0.35, 95%CI 0.21-0.59; p < 0001); mechanical ventilation (OR 0.56, 95%CI 0.39-0.80; p = 0.002); secondary bacterial pneumonia (OR 0.61, 95%CI 0.39-0.98; p = 0.04) and a higher degree of dependence (OR 0.74, 95%CI 0.55-0.99; p = 0.04). No association was observed for the Charlson comorbidity index or the mean hospital stay. Although influenza vaccination of the elderly may not achieve significant savings in mean hospitalization costs, it may lessen the degree of severity and avoid complications.
