Anti-rubella seroprevalence assessment in an adult sample population in Italy.

Introduction: Despite global immunization efforts, rubella remains a public health concern, particularly in high- and middle-income countries. This study focused on rubella seroprevalence in the province of Florence, Italy, aiming to identify susceptibility clusters, especially among women in their childbearing age. Methods: A cross-sectional study was conducted between April 2018 and December 2019, enrolling 430 adult subjects (age over 18 years). Serum samples were collected, and anti-rubella antibodies were quantified using the ELISA test. Data were analyzed descriptively and compared by sex, nationality, and age groups using statistical tests. Results: The overall rubella seroprevalence was high (92.3%), with no significant differences between genders or nationalities. Among childbearing-age females (18-49 years), the highest seroprevalence was observed in the 30-39 age group (94.1%). However, susceptibility clusters exceeding the 5% threshold set by WHO were identified, especially in females aged 40-49 years (7.0%). Conclusions: Despite high overall seroprevalence, the study identified pockets of susceptibility, even in childbearing age women. Continuous monitoring, targeted immunization strategies, and public health interventions are recommended to maintain rubella elimination, emphasizing the importance of sustained vaccination efforts to protect vulnerable populations.

Factors Influencing the Healthcare Workers' Willingness to Receive the COVID-19 Booster Dose in Tuscany (Italy).

BACKGROUND: The World Health Organization has defined vaccine hesitancy as behavior influenced by several factors, including trust in the vaccine itself or its provider or the perceived need for vaccination. The aim of this study was to investigate the factors influencing the willingness to receive the COVID-19 vaccine among the employees and healthcare professionals of the Central Tuscany Local Health Authority (CT-LHA) in Italy. METHODS: From July to October 2022, a cross-sectional study was conducted. An online questionnaire was administered to 7000 employees of the CT-LHA. The questionnaire analyzed the factors that influenced receiving the booster dose of the COVID-19 vaccine. The sample was stratified by gender, age, type of occupation (healthcare or non-healthcare workers), and seniority. Incomplete questionnaires were excluded. A chi-squared test was performed through STATA. The significance level was set at 95%. RESULTS: Of the questionnaires administered, 1885 (26.9%) questionnaires were eligible for the study. In the previous vaccination campaign, the healthcare workers (HCWs) considered the vaccine used by CT-LHA as safe, in contrast to non-healthcare workers (N-HCWs), who considered it less secure (p < 0.05). The HCWs showed a higher propensity for vaccine safety to receive the booster dose than N-HCWs. N-HCWs appeared to be less affected by an updated booster dose than HCWs (p < 0.05). CONCLUSIONS: The factors studied appear to influence HCWs differently from N-HCWs. Both HCWs and N-HCWs would choose an upgraded mRNA vaccine for the booster dose.

Health literacy and breast cancer screening adherence: results from the population of Tuscany, Italy.

Mammographic screening can reduce breast cancer (BC) mortality in women. In Italy, although attendance rates increased recently, they are still far from the recommended levels internationally. Inadequate health literacy (HL) may be a reason for poor awareness and/or knowledge about the importance of completing cancer screening. This study examined the relationship between HL, other sociodemographic determinants, and their influence on participation in both opportunistic and organized BC screenings among women aged 50-69 in Tuscany. The study analyzed 2017-2019 data from the Tuscan population subsample in the Italian Behavioral Risk Factor Surveillance System PASSI (Progressi delle Aziende Sanitarie per la Salute in Italia). HL was assessed using the Italian version of the six-item European Health Literacy Survey Questionnaire (HLS-EU-Q6). Among the 2250 interviewees, 75.3% underwent the organized BC screening and 9.4% on voluntary basis. Although to a different extent, HL was significantly associated to compliance rates with both opportunistic and organized screenings. Among sociodemographic factors, only occupational status was associated with opportunistic screening attendance rates. As expected, being invited by letter resulted to be strongly associated with participation to organized screening programs and the medical advice predicts for participating to both opportunistic and organized screening. This study highlights the relevant role that HL plays in BC, opportunistic and organized, screening adherence in a universal healthcare system. To increase BC screening participation rates, healthcare systems would benefit by implementing interventions for improved HL at population level or within healthcare organizations.

Electronic Package Leaflets for Vaccines: What Are People's Perceptions in Italy?

In Italy, the paper package leaflet (PPL) is the official document that is approved by the Italian Medicines Agency (AIFA) for each medicine. PPLs of all medicines, including vaccines, are freely available online by accessing the AIFA website. To investigate people's attitudes toward possible access to the PPLs of vaccines and the acceptability of switching to an electronic package leaflet (e-leaflet) in the future, we surveyed three target groups (pregnant women, young parents, and older people) in Italy, via an online survey. We collected 321 questionnaires from the cohorts, which comprised 104 pregnant women, 105 young parents, and 112 older people. The results indicate in all target groups that health care professionals (HCPs) do not usually offer the vaccine PPL during the vaccination session: only about 10.7% of respondents receive the PPL without asking for it, with pregnant women receiving it the most frequently. The acceptance rate for switching from a PPL to an e-leaflet is fairly high in all target groups (76.9% in pregnant women, 81.9% in young parents, and 66.1% in the elderly), especially if the option exists to request a paper print, to make sure that people with a low level of digital skills can access the PPL information as well. HCPs have an important role in ensuring access to the PPLs of vaccines. HCPs should be trained to inform their patients about the different options for accessing the PPLs (as well as online access) to increase their patients' knowledge and satisfaction.

Health Literacy, Socioeconomic Status and Vaccination Uptake: A Study on Influenza Vaccination in a Population-Based Sample.

Background: Health Literacy (HL) has been recently hypothesized to affect the relationship between socio-economic status (SES) and health conditions. However, to date no study has yet assessed the potential contribution of HL in the pathway through which SES affects influenza vaccination status. We aim to examine the relationships among HL, SES factors, and influenza vaccination uptake in Tuscan (Italy) residents belonging to different high-risk groups (HRGs) for influenza. Methods: The study was performed within the Tuscan population sample selected in the Italian Behavioral Risk Factor Surveillance System in 2017−2018. HL was assessed using the Italian version of the 6-items European Health Literacy Survey Questionnaire (HLS-EU-Q6). Mediation analyses were conducted using SES variables as independent variables, influenza vaccination status as dependent variable and HL as mediator variable. Results: A total of 3278 people belonged to HRGs for influenza. In the whole sample, 19.4% of the participants were vaccinated against influenza. Participants who were not employed or had a poor financial status were more likely to be vaccinated against influenza (OR 1.56, 95%CI 1.26−1.94, p < 0.001, and OR 1.21, 95%CI 1.00−1.48, p = 0.047 respectively). HL did not mediate the relationship of any of the independent variables with influenza vaccination status. Conclusions: Some SES determinants resulted to influence influenza vaccination uptake, while HL did not affect the likelihood of influenza vaccination uptake among HRGs. Universal health care systems, as in the case of Italy, offering influenza vaccination free of charge to HRGs help in reducing inequalities and mitigating HL demands.

Health Literacy, Socio-Economic Determinants, and Healthy Behaviours: Results from a Large Representative Sample of Tuscany Region, Italy.

BACKGROUND: Health Literacy (HL) is one of the main determinants of health and is crucial for the prevention of noncommunicable diseases, by influencing key health-related behaviours. The aim of the present study was to assess the role of HL and sociodemographic factors in predicting the adoption of two healthy behaviours-physical activity and fruits and vegetables consumption. METHODS: This study was conducted on the Tuscan population subsample of the Italian Behavioral Risk Factor Surveillance System in 2017-2018. HL was assessed using the Italian version of the six-item European Health Literacy Survey Questionnaire (HLS-EU-Q6). RESULTS: About 40% of the 7157 interviewees reported an inadequate or problematic HL level. Female sex, poor financial status, foreign nationality, and low education were associated with a problematic HL level, while an inadequate HL level was associated with being 50-69 years old, low education level, foreign nationality, poor financial status and unemployment or inactive status. Inadequate HL level was a strong predictor of both eating less than three portions of fruits/vegetables per day and not engaging in sufficient PA during leisure times. CONCLUSIONS: Our findings showed that an inadequate level of HL could negatively affect physical activity and diet, independently from the other sociodemographic conditions, confirming the role of HL as a relevant social determinant of health.

A Study of Hepatitis A Seroprevalence in a Paediatric and Adolescent Population of the Province of Florence (Italy) in the Period 2017-2018 Confirms Tuscany a Low Endemic Area.

Background: Italy is considered an area with very low HAV (hepatitis A virus) endemicity. Currently in Italy the anti-HAV vaccine is recommended only for specific risk groups and there is no universal vaccination program. The aim of this study was to assess the level of immunity against hepatitis A in a sample of children and adolescents from the province of Florence. Methods: A total of 165 sera were collected from subjects aged 1 to 18 years, proportionally selected according to the general population size and stratified by age and sex. A qualitative evaluation of anti-HAV antibodies was performed using the enzyme-linked immunosorbent assay (ELISA). Anamnestic and vaccination status data were also collected. Results: Our study showed a hepatitis A seroprevalence of 9.1% in the enrolled population. A statistically significant difference in the prevalence of anti-HAV was found between Italian and non-Italian subjects. About half of the population having anti-HAV antibodies was reported to be vaccinated, and no cases of hepatitis A were found. Conclusions: The data from our study confirmed Tuscany as an area with low HAV endemicity and showed that hepatitis A seroprevalence is significantly higher in foreign children and adolescents. The presence of more seropositive subjects than those vaccinated was probably due to a natural immunization achieved through a subclinical infection and/or to underreporting of the surveillance systems.

Descriptive Observational Study of Tdap Vaccination Adhesion in Pregnant Women in the Florentine Area (Tuscany, Italy) in 2019 and 2020.

Background: Tdap (Tetanus-Diphtheria-acellular Pertussis) vaccination is nowadays a worldwide-recommended practice to immunize pregnant women. The vaccine administration at the third trimester of pregnancy (as recommended by the WHO) would ensure antibody protection to both the mother and the newborn and has contributed to the significant drop of pertussis cases in infants. The aim of this observational study was to describe for the first time the socio-demographic characteristics and determinants of Tdap vaccination adhesion of pregnant women in the Florentine area. Methods: Information about parents' vaccination status, their citizenship, employment type and mothers' previous pregnancies and/or abortions were collected at the time of birth through the assistance birth certificates (CedAP) both for the years 2019 and 2020. This archive and the regional SISPC (Collective Prevention Healthcare Information System) linked using an anonymous unique personal identifier to retrieve the mother's vaccination status. Results: We found an overall Tdap vaccination adhesion of 43% in 2019 and 47.3% in 2020. Several socio-demographic parameters would determine an increased vaccination adhesion, including parents' geographical origin, mothers' age and educational background, as well as the number of previous deliveries, abortions or voluntary termination of pregnancy. Conclusions: Since not much data are available on this topic in Italy, this study may constitute the baseline information for Tdap vaccination adhesion in pregnant women in the Florentine area (Italy). Thus, future successful vaccination strategies may be designed accordingly.

Reduction in Neisseria meningitidis infection in Italy after Meningococcal C conjugate vaccine introduction: A time trend analysis of 1994-2012 series.

The incidence of invasive meningococcal disease (IMD) in Italy is among the lowest in Europe. Meningococcal C conjugate vaccine (MCC) was introduced in 2005 for 12 months old infants. The aim of this study was to describe the epidemiology of IMD in Italy from 1994 to 2012 and to evaluate the impact of MCC introduction. Data about Neisseria meningitidis (N. meningitidis) cases were drawn from the National Surveillance of Invasive Bacterial Diseases. The average incidence of IMD during 1994-2012 in Italy was 0.36 per 100,000 (95%CI 0.30; 0.40). N. meningitidis B was the most frequent serogroup and infants less than 12 months old were the most affected. Joinpoint analysis showed a statistically significant reduction in the incidence of N. meningitidis C related IMD after MCC introduction: the Annual Percentage Change declined from 21.8 (95%CI 15.1; 28.9) in 1994-2005 to -19.9 (95%CI -28.2; -10.7) afterwards. No changes were observed with respect to N. meningitidis B related IMD. Poisson regression showed a statistically significant reduction in the incidence of IMD both associated to N. meningitidis C (Incidence Rate Ratio 0.33; 95%CI 0.29; 0.37) and due to all serogroups (Incidence Rate Ratio 0.70; 95%CI 0.65; 0.75) in the post-vaccination period compared to the pre-vaccination one. On the other hand, the incidence of N. meningitidis B related IMD did not decrease. Our results suggest that MCC had an impact in decreasing the incidence of N. meningitidis C related IMD. However, data on typing are incomplete and efforts are needed to make them available for studying the need and the impact of other meningococcal vaccines.
