A Study of Vitamin D Status and Its Influencing Factors among Pregnant Women in Szeged, Hungary: A Secondary Outcome of a Case-Control Study.

Adequate vitamin D (VD) intake during pregnancy is needed for fetal development and maternal health maintenance. However, while there is no doubt regarding its importance, there is not a unified recommendation regarding adequate intake. The main aim of our study was to measure the VD serum level of studied women, together with its potential influencing factors: demographic (i.e., age, level of education, relationship status and type of residence), conception and pregnancy related factors. Results are based on secondary data analyses of a retrospective case-control study of 100 preterm and 200 term pregnancies, where case and control groups were analyzed together. Data collection was based on a self-administered questionnaire, health documentation, and maternal serum VD laboratory tests. VD intake was evaluated by diet and dietary supplement consumption. According to our results, 68.1% of women took some kind of prenatal vitamin, and only 25.9% of them knew about its VD content. Only 12.1% of included women reached the optimal, 75 nmol/L serum VD level. Higher maternal serum levels were associated with early pregnancy care visits (p = 0.001), assisted reproductive therapy (p = 0.028) and advice from gynecologists (p = 0.049). A correlation was found between VD intake and serum levels (p < 0.001). Despite the compulsory pregnancy counselling in Hungary, health consciousness, VD intake and serum levels remain below the recommendations. The role of healthcare professionals is crucial during pregnancy regarding micronutrients intake and the appropriate supplementation dose.

[Knowledge and attitudes about vaccinations among medical students during the COVID-19 pandemic]. / A védooltásokkal kapcsolatos ismeretek és attitudök orvostanhallgatók körében a COVID­19-pandémia alatt.

INTRODUCTION: In Hungary, regarding the age-related mandatory vaccinations, the population is almost 100% vaccinated. In the case of recommended vaccinations, however, the situation is less favourable, and during the COVID-19 pandemic, anti-vaccination sentiment has also appeared in some groups to a greater extent than before. Reducing this is the task of all health professionals. OBJECTIVE: The exploration of knowledge and attitudes about vaccinations, and the analysis of the characteristics of these factors according to gender, year and vaccine willingness/hesitancy among medical students at the University of Szeged. METHOD: The cross-sectional study was conducted among first and fourth year medical students of the University, using an online questionnaire, which examined, in addition to sociodemographic characteristics, the administration of influenza and COVID-19 vaccinations, the self-assessment of knowledge about vaccinations, the importance of vaccinations, and student opinions about recommended vaccinations. RESULTS: Based on the definition of the WHO Strategic Advisory Group, 88.6% of the students belonged to the "vaccine willingness" group, who administered the vaccine against COVID-19 as soon as it became available, while the "vaccine hesitancy" group (11.4%) only asked for the vaccine when vaccination was made mandatory or not even then. According to the model adjusted to gender and year, those who showed willingness to vaccinate were more likely to consider the use of vaccinations, counselling, etc. important than those who were hesitant, while there was no correlation with the self-rating of knowledge. On the basis of the odds ratio of the statements related to the recommended vaccinations, it was possible to identify the opinions associated with vaccine willingness or hesitancy. DISCUSSION: Overall, student knowledge and attitudes showed a positive picture. On the other hand, it should be emphasized that the misconceptions identified among students showing vaccine hesitancy are the same as the anti-vaccination sentiments found among the general population. CONCLUSION: During university training, more emphasis should be placed on monitoring the willingness of students to be vaccinated, and on developing knowledge and communication.
