Sociodemographic determinants of vaccination and willingness to pay for COVID-19 vaccines in Hungary, results of a cross-sectional online questionnaire

BackgroundSeveral different coronavirus disease (COVID-19) vaccines were authorized and distributed all over the world, including Hungary, but vaccination rates and acceptance of the different vaccines varied through 2021 and subsequent years. In Hungary Western vaccines and the Chinese and Russian vaccines were available in early 2021. Understanding preference and willingness to pay (WTP) for the COVID-19 vaccine could provide information for policy decision making to control the COVID-19 pandemic. We aimed to assess the socio-demographic factors influencing the COVID-19 vaccination and to analyse individual preferences for the available COVID-19 vaccines in Hungary.MethodsA cross-sectional online questionnaire survey was conducted between 25–05-2021 and 08–06-2021 exploring the vaccine acceptance and WTP for vaccination in the Hungarian general population. To assess the preferences towards the different vaccines available in Hungary at the time of the study, we used a multi-step WTP task.ResultsAltogether 2,000 respondents filled out our survey, with the average age of 49.1 (SD = 15.3), out of whom 370 respondents (18.5%) stated that they already had a COVID-19 infection. Age above 65 years, male gender, higher level of education, higher income and residence in the capital or county seats were associated with a higher probability of vaccination. The average WTP ranged from 14.2 to 30.3 EUR for the different vaccine types.ConclusionsMales, respondents with higher education and income stated a higher WTP value for all vaccines. Better socioeconomic status increased both vaccination coverage and willingness to pay for vaccines.

Comparative Health Behaviour of Young People with Disabilities in Hungary: A Cross-Sectional Study.

The health status of Hungary's population is unfavorable, with significant differences in health indicators not only compared to the EU15 but also to the Visegrad countries. Unfavorable health indicators can be disproportionate and particularly affect vulnerable groups, such as people with disabilities. In this study, we set out to compare the health behavior of disabled youth and youth with typical development in Hungary. We also aimed to compare the health behavior of adolescents in the Visegrad countries. The eating habits of both groups of young people we examined are unfavorable. Adolescents with disabilities experience a significantly higher rate of school stress than children with typical development in Hungary. The prevalence of somatic complaints and parameters of poor mental well-being are significantly higher in Hungary than in the other Visegrad countries. The results indicate that additional interventions are needed in Hungary and that differentiated, professional health promotion is needed for young people with disabilities. The researchers recommend extending the study to disabled adolescents living in Visegrad countries, on the basis of which an injury-specific health promotion methodology could be developed with international interprofessional cooperation.

National eye health data from the Hungary's Comprehensive Health Protection Screening Program 2010–2020–2030 (MÁESZ)

AbstractPurposeThis paper provides a detailed presentation of the estimated number of people in Hungary with eye disease and refractive errors by both sex and age.Materials/methodsIn the past 12 years, 168,522 people (54.1% women and 45.9% men) have been screened under Hungary's Comprehensive Health Protection Screening Programme (MÁESZ).ResultsThe total number of people with eye disease in the adult Hungarian population (about 8 million people) is estimated to be 1,684,818, with women (1,078,026) outnumbering men (606,792). Eye diseases were found to be more common in older age groups, and more common in women than men in each age group. The estimated number of people with refractive errors in the Hungarian adult population is 5,005,095. The overall number of people with myopia in the adult Hungarian population is estimated to be 3,058,536, with roughly equal numbers of men and women. The majority of people with myopia (63.3%) are between 18 and 45 years of age.ConclusionsThe huge number of people in the Hungarian population affected by eye disease or refractive errors underscores the need to develop and implement an effective national strategy and specific programmes to prevent visual impairments.

Incident Cancer Risk in Patients with Incident Type 2 Diabetes Mellitus in Hungary (Part 1).

(1) Background: Patients with type 2 diabetes mellitus (T2DM) are at higher risk of cancer but how these two diseases associate is still debated. The goal of this study was the assessment of the overall incidence of cancer among patients with newly diagnosed T2DM in Hungary. (2) Methods: A nationwide, retrospective, longitudinal study was performed using a Hungarian database. After exclusion of cases of age < 18 years, with gestational diabetes, with polycystic ovary syndrome, and with type 1 and prevalent type 2 diabetes mellitus, the incident T2DM (approx. 50,000 cases yearly) and for comparison, the diabetes-free Hungarian adult population (approx. 7,000,000 cases yearly) was included in the study. The primary endpoints were the overall and site-specific incidence and annual percentage change of the incidence of cancer in both populations. (3) Results: The overall incidence of cancer in patients amounted to 29.4/1000 and 6.6/1000 with or without T2DM, respectively, and the OR (95%CI) of cancer of the T2DM group was 4.32 (4.14-4.53), p < 0.0001. The risk of having cancer was age dependent. The incidence of cancer was declining in the non-diabetic but was unchanged in the T2DM population. The average lag time of diagnosing cancer after the detection of T2DM was 3.86 months. (4) Conclusions: Incident T2DM is associated with a significantly higher overall risk of incident cancer, with a reverse correlation of age. Newly registered T2DM patients were suggested to be screened for cancer within 6 months.

Monetary valuation of one year in full capability and health based on demographics, health status, income and well-being

ABSTRACT Background Budget constraints in health-care systems have led to the popularity of Cost Effectiveness Thresholds (CET) to achieve efficient allocation of resources. The capability approach has been hailed for its potentially richer evaluative capabilities compared to the QALY in terms of thresholds. Extensive research, however, is still limited. Research design and methods This study estimated the monetary value of a year in full capability (YFC) and compared it to monetary value of a QALY for the Hungarian population. Data was collected from a large, cross sectional, representative online survey on the adult Hungarian population. Applying the wellbeing valuation method, health, capability, and income were then regressed against wellbeing to estimate ‘shadow prices’ for one QALY and YFC controlling for gender, age, employment, education, marital and social support. To examine ‘core’ regression coefficients, a robustness check was conducted. Results Health (VAS) and capability (ICECAP-A) had a positive and significant effect on Subjective Well-Being. The monetary values of one QALY and one YFC were 39 459 EUR and 58 148 EUR respectively. Conclusions These tools provide a systematic approach to determining ‘compensating income’ for certain illnesses, disabilities and levels of pain. The capability approach shown to be broader than the QALY.

Analysis of beliefs about COVID-19 vaccines among the adult Hungarian population from a health communication perspective

Bevezetés: A magyar lakosság az európai uniós átlaghoz képest kisebb arányban vette fel a COVID–19 elleni védőoltást. A hazai deprivált települések lakosainak körében az oltás felvétele pedig 38,2%-kal volt kisebb arányú az országos átlaghoz képest. Az oltási program egyik legfőbb akadálya a lakossági bizalmatlanság volt. Célkitűzés: A COVID–19-védőoltással kapcsolatos lakossági hiedelmek feltárása és a járvánnyal kapcsolatos tájékozódásra használt tömegmédiumok azonosítása. Módszer: Az elemzett adatok egy 2022. november 15–26. között zajlott keresztmetszeti, online kérdőíves felmérésből származnak. Az anonim adatfelvétel effektív mintaelemszáma 1222 fő volt. A COVID–19 elleni védőoltás elutasítását, szociodemográfiai változókat, 5 pozitív és 5 negatív, a védőoltással és a COVID–19-cel kapcsolatos attitűdállítást, valamint a járvánnyal kapcsolatos tájékozódásra használt tömegmédiumokra vonatkozó kérdéseket vontunk be a vizsgálatba. Frekventista statisztikai eszközöket és Hornik–Woolf-becslést alkalmaztunk. Eredmények: „A beoltottak védik a környezetükben élők egészségét is” állítással való egyetértés sikeres megerősítése érhette volna el a legnagyobb átoltottságnövekedést a magyar felnőtt lakosság körében. A válaszadók a tömegmédiumok közül a televíziót, az online hírportálokat, a kormányzati online kommunikációt, valamint a rádiót jelölték meg mint elsődleges információforrást. A zárt Facebook-oldalakon és a YouTube-on szignifikánsan több oltáselutasító tájékozódott, mint oltáselfogadó. Következtetés: A nemzetközi eredményekkel összhangban Magyarországon is a közösségi érdek és a felelősség hangsúlyozása lehetett volna a szerencsés általános megközelítés a COVID–19 elleni védőoltás felvételének tömegkommunikációjában. Jövőbeli átfogó lakossági oltási kampány előkészítéséhez többszintű egészségkommunikációs felmérés, tervezés és tesztelés ajánlható. Orv Hetil. 2024; 165(17): 664–671.

Nutritional Habits of Hungarian Older Adults.

There are many nutritional changes that come with aging, mostly as consequences of health regression. Malnutrition and overweight often start with inadequate food consumption, followed by alterations in biochemical indices and body composition. In our study, we aimed to analyze the feeding habits and energy and nutrient intake of a Hungarian elderly population, focusing on macronutrient, water, fruit, and vegetable consumption while searching for possible nutritional factors leading to NCD and many other chronic diseases in this population. Two questionnaires were used. These were the Mini Nutritional Assessment (MNA) and one asking about nutritional habits, and a 3-day feeding diary was also filled. Subjects (n = 179, 111; females (F), 68 males (M), older than 50 years were recruited. Based on MNA results, 78 adults (43.57% of the studied population) were malnourished or at risk of malnutrition, although, according to BMI categories, 69% were overweight and 7.3% were obese among M, while 42.3% were overweight among F. The average daily meal number was diverse. The amount of people consuming fruit (11.7%) and vegetables (8.93%) several times a day was extremely low (15.3% of F and 4.4% of M). Daily fruit consumption in the whole sample was 79.3%. Overall, 36.3% consumed 1 L of liquid and 0.5 L of consumption was found in 15.1% of participants. A significant gender difference was found in water consumption, with F drinking more than M (p ≤ 0.01). In our sample, 27.93% of the respondents took dietary supplements. Further analysis and research are needed to explore the specific health implications of and reasons behind these findings.

Subjective Well-Being Population Norms and Inequalities in Hungary: A Large Cross-Sectional, Internet-Based Survey

ObjectivesThis study aimed to provide subjective well-being (SWB) population norms in Hungary and explore the contribution of explanatory factors of SWB inequality among the Hungarian adult general population. MethodsThe data originated from a large representative internet-based cross-sectional survey in Hungary, which was conducted in 2020. We applied validated multi-item instruments for measuring SWB, namely Satisfaction With Life Scale (SWLS) and World Health Organization-Five Well-Being Index (WHO-5). Multiple linear regressions were used to examine the relationship between demographic-socioeconomic-health status and both well-being instruments. The concentration index (CI) was used to measure the degree of income-related inequality in well-being. ResultsA total of 2001 respondents were enrolled with the means ± SD WHO-5 scores and SWLS scores of 0.51 ± 0.21 and 0.51 ± 0.23, respectively. Higher household income, higher educational level, better general health status, and absence of chronic morbidity were significant positive predictors for both WHO-5 and SWLS scores. The CI of WHO-5 scores was lower than that of SWLS scores in the total sample (0.0480 vs 0.0861) and in subgroups by gender (male, 0.0584 vs 0.1035; female, 0.0302 vs 0.0726). The positive CI values implied a slight pro-rich SWB inequality in this population. The regression analyses showed a positive association of SWB with having a higher household income and a better general health status. ConclusionsThis is the first representative study in Hungary to compare population norm of 2 well-being instruments and analyze well-being inequality. Slight pro-rich inequality was found consistently with both SWB measures. Our findings support the need for health and social policies that effectively tackle inequalities in Hungary.

Understanding genetic variability: exploring large-scale copy number variants through non-invasive prenatal testing in European populations.

Large-scale copy number variants (CNVs) are structural alterations in the genome that involve the duplication or deletion of DNA segments, contributing to genetic diversity and playing a crucial role in the evolution and development of various diseases and disorders, as they can lead to the dosage imbalance of one or more genes. Massively parallel sequencing (MPS) has revolutionized the field of genetic analysis and contributed significantly to routine clinical diagnosis and screening. It offers a precise method for detecting CNVs with exceptional accuracy. In this context, a non-invasive prenatal test (NIPT) based on the sequencing of cell-free DNA (cfDNA) from pregnant women's plasma using a low-coverage whole genome MPS (WGS) approach represents a valuable source for population studies. Here, we analyzed genomic data of 12,732 pregnant women from the Slovak (9,230), Czech (1,583), and Hungarian (1,919) populations. We identified 5,062 CNVs ranging from 200 kbp and described their basic characteristics and differences between the subject populations. Our results suggest that re-analysis of sequencing data from routine WGS assays has the potential to obtain large-scale CNV population frequencies, which are not well known and may provide valuable information to support the classification and interpretation of this type of genetic variation. Furthermore, this could contribute to expanding knowledge about the central European genome without investing in additional laboratory work, as NIPTs are a relatively widely used screening method.

Investigating the effect of grit trait on performance and success in Hungarian athlete's sample.

The aim of the present study is to translate the Grit questionnaire into Hungarian and validate specifically within the context of sports. The second goal is to assess the questionnaire in Hungarian as a pilot study in the athlete population and to compare the grit trait with the coaches' athlete evaluation. Two hundred and sixty nine athletes, including 40 national team players, took part in the study, with an average age of 18.17 years (SD = 5.51). For the preliminary assessment, the Cloninger Temperament and Character Questionnaire (TCI-RH) was used; the coaches' athlete evaluation was modeled on a talent map. The confirmatory factor analysis confirmed the fit of the two-factor structure, and the internal reliability of the questionnaire scales also proved to be adequate. 2. There is no relationship between adolescents' perceived grit and coach ratings. 3. The national team players achieved a higher grit score. Based on the psychometric indicators, the validity and reliability of the questionnaire proved to be adequate. Therefore, it is applicable and useful for psychological practitioners and researchers in the Hungarian population within the context of sports.

A Computed Tomography Study on the Prevalence of Lusorian Artery Among Hungarian Adults.

Introduction The aberrant right subclavian artery (ARSA), also called as lusorian artery (LA) is a developmental anomaly that exists in conjunction with a right non-recurrent laryngeal nerve (NRLN) in almost all cases. The average prevalence of such a vascular variation is estimated as 1%, although, studies have reported very different population means. Up to date, there is no available data on the frequency of this pattern in the Hungarian population. It can be treated as an indirect marker of a NRLN. Any preoperative information on the course of the inferior laryngeal nerves can help surgeons reduce the risk of an iatrogenic injury during thyroidectomies, especially in an environmentwhere access to intraoperative neuromonitoring is limited. Objectives The primary aims were to determine the prevalence of an ARSA, predict the existence of an NRLN in the Hungarian population, and provide demographic analysis. Methods A retrospective, computed tomography-based study was carried out. Demographic description and statistical analysis were provided where applicable. Detected anomalous vasculatures were visualized with 3D segmentation, and images were interpreted. Results The imaging database review identified three patients with ARSA out of 686 eligible recordings, resulting in a frequency of 0.437% in the study population. All three patients were female and had a retroesophageal LA. Two of them had a Kommerell's diverticulum. One patient had common carotid arteries with a single origin. Conclusions The frequency of an ARSA and a concomitant NRLN among Hungarians fits into the results of recent meta-analyses. Preoperative assessment of this anomaly may reduce vocal cord complication rates of thyroidectomies.

Spatial-temporal analysis of urban climate dynamics in major Hungarian cities

Increasing heatwaves are making cities and their populations more vulnerable, parallel to urban sprawl and the aging population in Hungary. The increasing number of hot days is predicted to worsen urban climate anomalies at the local scale, which, in parallel with changing land use patterns, may contribute to a significant increase in vulnerability to heatwaves. Local stakeholders and decision-makers need to understand the critical role of spatiotemporal land use—land cover (LULC) patterns and urban climate aspects to address relevant challenges for urban development. The current literature does not contain a synthesis analysis of major Hungarian cities that includes urban climate and sustainability findings hand by hand; therefore, this study aims to analyze LULC patterns, urban hotspots and surface urban heat island effects. In addition, the Normalized Difference Vegetation Index (NDVI) was determined as an important indicator for assessing the health and density of green spaces in major Hungarian cities from 2006 to 2018 using remote sensing data. Our results show that each city experienced significant urban sprawl, while above-average NDVI areas decreased over time. The average increase in the share of built-up areas was 1.3% from 2006 to 2018, while the calculated average decline in agricultural areas was 2%, so the expansion of residential areas and artificial areas is not the only driving force of this shrinking trend in agricultural areas. Furthermore, we found that urban hotspots are generally concentrated in industrial areas and represent new spaces of heat islands on the outskirts of cities. Székesfehérvár has the most intense industrial heat islands, with the largest proportion of urban hotspots (approximately 3.5% of the total area) concentrated in industrial zones. Our study contributes to uncovering inter-urban processes of land use patterns and urban climate issues in major Hungarian cities, moreover revealing sustainability-related issues from a lock-in perspective.

New approaches in the neuropsychological evaluation of aADHD

IntroductionIn Hungary, the understanding and diagnosis of adult attention-deficit/hyperactivity disorder (aADHD) are influenced by a blend of international epidemiological data and the standardized criteria established in DSM-5. The diagnostic protocols at our aADHD Outpatient Clinic at Semmelweis University have been carefully adjusted and validated to align with the practical application of empirical evidence and the extensive clinical expertise of professionals. The current diagnostic protocol encompasses the use of diagnostic interviews (symptoms identification based on DSM criteria; SCID-5-PD; M.I.N.I.-PLUS-5.0), the Conners’ Adult ADHD Rating Scales–Self Report questionnaire (CAARS), heteroanamnesis with parents, a comprehensive neuropsychological instruments battery (including the Rey Auditory Verbal Learning Test, Stroop Test, Conners-CPT3, Trail Making Test) and WAIS-IV Intelligence Scale.ObjectivesA valid and appropriate diagnosis plays a crucial social role by legitimizing individuals’ attention/health issues, confirming their concerns, and addressing cultural and moral expectations. The primary objective of this work is to refine the diagnostic methodology by extensive review of the international literature and the analysis of our own data.MethodsWith the aim of aggregating and analyzing the collected data based on examinations of the Hungarian adult population, our assessment methods are employed to acquire detailed information regarding ADHD prevalence, symptoms, and the related neuropsychological profiles.ResultsWhile various diagnostic approaches generally demonstrated good alignment, in some cases, significant discrepancies between neuropsychological assessment and the rest of our tools were observed, indicating a number of instances of false positives or false negatives. Especially the relevance of Rey Auditory Verbal Learning Test and Trail Making Test are questionable.ConclusionsThe results highlight the necessity for more refined diagnostic criteria and a meticulous selection of neuropsychological techniques to enhance consistency between various approaches, ultimately enabling a more robust diagnostic accuracy.Disclosure of InterestNone Declared

Changes in public attitude toward epilepsy in Hungary since 1994. A multicriteria weighting analysis.

To assess the adult Hungarian population's knowledge about and attitude toward epilepsy and compare the present findings with previous ones in 1994 and 2000. We performed a cross-sectional survey of the Hungarian adult population from 28th February to 8th March 2023. A non-probability quota sampling with a random walk method was used. We applied the computer-assisted personal interviewing (CAPI) method and used a multicriteria weighting procedure to correct for bias along the main sociodemographic variables. To detect changes over time, we used chi-squared tests, and to analyze the effect of sociodemographic characteristics, we applied multivariate logistic regression. One thousand participants (53.1% women, mean age 48.1 ± 16.75 years) representing Hungary's population were interviewed yielding a response rate of 80.3%. 26.3% knew someone with epilepsy (55.9% in 1994 and 51.9% in 2000), and 30.8% saw an epileptic seizure (58% in 1994 and 55.3% in 2000). Compared to the young, fewer adults and elderly people knew someone with epilepsy or had seen a seizure. Like in 1994 and 2000, 16.6% reported objection to their children's interaction with people with epilepsy; however, in the present study, significantly fewer people opposed their children marrying or working together with epileptic people, indicating a change in attitude (p < 0.0001). Rural residents had less objection to their children's interaction with people with epilepsy (p < 0.05). People with secondary education objected significantly more often than those with primary education to their children's interaction (p = 0.037), marriage to people with epilepsy (p = 0.043), or their having equal employment (p = 0.008). Higher education people were as "permissive" as those with primary education. Certain parameters of familiarity and attitude markers of the Hungarian population toward epilepsy have improved. These tendencies are promising, but work is still needed; our results will hopefully evoke educational programs and campaigns against negative attitudes. The knowledge of the Hungarian population about epilepsy and their attitude toward people with epilepsy has been improved since 1994. People from rural areas have shown more acceptance for people with epilepsy. Those people who completed secondary education were significantly more prone to stigmatization than those with primary education.

First Results on the Presence of Mycotoxins in the Liver of Pregnant Fallow Deer (Dama dama) Hinds and Fetuses.

Reproductive abnormalities have been observed in fallow deer populations in Hungary. We supposed mycotoxin contamination to be one of the possible causes because multi-mycotoxin contamination is known to be dangerous even at low toxin levels, especially for young animals. We investigated the spatial pattern of mycotoxin occurrences and the relationship between maternal and fetal mycotoxin levels. A total of 72 fallow deer embryos and their mothers were sampled in seven forested regions in Hungary in the 2020/2021 hunting season. We analyzed Aflatoxin (AF), Zearalenone (ZEA), Fumonizin B1 (FB1), DON, and T2-toxin concentrations in maternal and fetal livers by ELISA. AF was present in 70% and 82%, ZEA in 41% and 96%, DON in 90% and 98%, T2-toxin in 96% and 85%, and FB1 in 84% and 3% of hind and fetus livers, respectively. All mycotoxins passed into the fetus, but only Fumonizin B1 rarely passed. The individual variability of mycotoxin levels was extremely high, but the spatial differences were moderate. We could not prove a relation between the maternal and fetal mycotoxin concentrations, but we found an accumulation of ZEA and DON in the fetuses. These results reflect the possible threats of mycotoxins to the population dynamics and reproduction of wild fallow deer.

Can online banking replace personal banking? A survey of Hungarian banking habits

AbstractOne of the important issues of banking today is the role bank branches and online banking solutions play in serving consumers. With the help of a representative Survey of 1,000 adults in Hungary conducted in 2022, we examine how well online and mobile banking solutions can provide a suitable alternative to bank branches. Based on our results, online banking solutions cannot fully replace personal banking in Hungary due to the customers' attitudes, as we can see that their use does not significantly affect the frequency of visits to the bank branch, and their usage rate does not increase with the distance from the bank branch. We also point out that for the Hungarian population the trend of bank branch closures may entail the risk of being left out of the formal financial system mostly for the older, digitally less receptive social strata living in small settlements and in a relatively worse financial situation.

Genetic Background of Acute Heart Rate Response to Exercise.

The acute heart rate response (AHRR) to physical activity, which refers to the change in heart rate during and after exercise, has been associated with cardiovascular and all-cause mortality. Previous studies have shown that AHRR is significantly determined by genetics in addition to environmental and lifestyle factors. The aim of this study was to investigate the genetic background of AHRR by analysing ten single nucleotide polymorphisms (SNPs) associated with leisure-time physical activity (LTPA) in 620 samples from the Hungarian population. The AHRR can be characterised as the difference between post-exercise and resting heart rate, i.e., the delta heart rate (ΔHR) defined by the YMCA 3 min step test, with a lower value indicating better cardiovascular fitness. The association of SNPs with ΔHR was analysed both separately and in combination using an optimised polygenic score (oPGS). The results showed that five SNPs (rs10252228, rs459465, rs6022999, rs8097348, and rs12405556) had at least nominally significant (p < 0.05) individual associations with ΔHR. After optimizing the PGS, a cumulative effect was observed for eight SNPs (rs6022999, rs12405556, rs459465, rs10252228, rs8097348, rs10887741, rs12612420, and rs7023003) that had a strong and statistically significant association with ΔHR (B = -2.51, 95% CI: -3.46--1.76; p = 2.99 × 10-9). Of the four main domains of physical activity, the oPGS showed a significant positive association only with LTPA (B = 84.60; 95%CI: 25.23-143.98; p = 0.005). In conclusion, our results suggest that the SNPs we investigated influence individual leisure-time physical activity, mediated by their effects on the acute heart rate response.

Relationship between Social Networks, Support Patterns, and Health Problems among the General Hungarian Population during the Last Phase of the COVID-19 Pandemic

Numerous research works prove that social relationships and the support they provide have particular importance in maintaining both mental and physical health: they help to deal with stressful life situations, overcome diseases, and maintain health. It is also known that certain periods of life and life events can be critical in terms of social support, as they involve the narrowing of possible sources of support, so the lack of a network of contacts and social support increases not only the risk of becoming lonely but also the occurrence or worsening of diseases. This study investigates the relationship between social network factors and support provided through networks and health problems, taking into account the perceived personal and general impact of COVID-19. The data came from a cross-sectional study, a representative sample of 5000 Hungarian participants was conducted during the dwindling period of the pandemic. We used a latent profile analysis to separate the different groups of respondents based on the support received from different sources of relationships, aiming at capturing the diversity of supported support combinations based on the type of relationships in the network, the form of support, and frequency. Multilevel regression was used to examine the impact of social connectivity factors, emerging patterns, and COVID-19-related perceived consequences on health conditions. Our results confirm that the “poorly supported network” plays a key role in the occurrence of chronic diseases and depression. It seems interesting, however, that the probability of poor physical and mental health was higher in the group of those receiving financial and in-kind support mainly from family compared to the group of those receiving support from multiple sources of relationships. The models also suggest that network integration plays a major role in maintaining mental and physical health during an epidemic crisis.

A phylogenetic study of the Mongolian Tree Pipit (Anthus trivialis, Linnaeus, 1758) population based on mitochondrial DNA (mtDNA) genes

Our aim was to identify nucleotide polymorphisms, assess their distribution in haplotype diversity, and construct a phylogenetic tree by analyzing mtDNA markers of the Mongolian Tree Pipits(Anthus trivialis). We conducted this study using partial gene sequencesof mitochondrial marker genes, such as COI, Cyt-b, D-loop, andND2,to determine the genetic diversity of Mongolian Tree Pipits. We successfully amplified 2307 bp of the mitochondrial DNA fragments, including 469bp of COI, 435bp of Cyt-b, 554bp of D-loop and 846bp of ND2 from total 27 individuals of Mongolian (21) and Hungarian (6) populations of Anthus trivialis.The Hd value wasthe highest for ND2 (0.96) as compared with the other gene fragments in all populations, whileit was 0.94 in the Mongolian population. Moreover, the nucleotide diversity (Pi) ranged from 0.00234 to 0.004 in all population, it was observed that the Pi was between 0.00183 and 0.00376 in the Mongolian population. The phylogenetic tree based on combined mtDNA sequences revealed two mean clades. The probability value of the node supporting the posterior between these clades is 0.65,which suggests an indicative support in relationship between the two clades. Furthermore, phylogenetic analysis showed that Mongolian Tree Pipits do share common genetic characteristics with other populations and do not form distinct clusters.
