RESUMO

Understanding how the infectious disease burden was affected throughout the COVID-19 pandemic is pivotal to identifying potential hot spots and guiding future mitigation measures. Therefore, our study aimed to analyze the changes in the rate of new cases of Poland's most frequent infectious diseases during the entire COVID-19 pandemic and after the influx of war refugees from Ukraine. We performed a registry-based population-wide study in Poland to analyze the changes in the rate of 24 infectious disease cases from 2020 to 2023 and compared them to the prepandemic period (2016-2019). Data were collected from publicly archived datasets of the Epimeld database published by national epidemiological authority institutions. The rate of most of the studied diseases (66.6%) revealed significantly negative correlations with the rate of SARS-CoV-2 infections. For the majority of infectious diseases, it substantially decreased in 2020 (in case of 83%) and 2021 (63%), following which it mostly rebounded to the prepandemic levels and, in some cases, exceeded them in 2023 when the exceptionally high annual rates of new cases of scarlet fever, Streptococcus pneumoniae infections, HIV infections, syphilis, gonococcal infections, and tick-borne encephalitis were noted. The rate of Clostridioides difficile enterocolitis was two-fold higher than before the pandemic from 2021 onward. The rate of Legionnaires' disease in 2023 also exceeded the prepandemic threshold, although this was due to a local outbreak unrelated to lifted COVID-19 pandemic restrictions or migration of war refugees. The influx of war migrants from Ukraine could impact the epidemiology of sexually transmitted diseases. The present analysis indicates that continued efforts are needed to prevent COVID-19 from overwhelming healthcare systems again and decreasing the control over the burden of other infectious diseases. It also identifies the potential tipping points that require additional mitigation measures, which are also discussed in the paper, to avoid escalation in the future.

RESUMO

Hepatitis A virus (HAV) is the most common cause of acute viral hepatitis, which is preventable by vaccination. This study analyzed trends of HAV infections in Poland according to socio-demographic features in the years 2009-2022 and assessed the potential impact of the COVID-19 pandemic (2020-2023) and the migration of war refugees from Ukraine (since February 2022). In 2009-2022, 7115 new cases of HAV infection were diagnosed in Poland, especially among men (66.4%) and in urban areas (77.4%). Infections among men were most common at the age of 25-34 (median rate 0.43 per 105) and in women aged 15-24 (median rate 0.39 per 105). Analysis of the 14-year frequency of HAV infections exhibited three trends, regardless of gender, age, and residence. The infections revealed a downward trend in 2009-2014, increased significantly in 2014-2018, and decreased again after 2018. A particularly rapid increase in HAV infections occurred between March 2017 and February 2018 (median rate 0.79 per 105). The high level of new infections persisted until the beginning of the COVID-19 pandemic, at which point it dropped significantly but did not reach the level recorded before March 2017. During the Omicron SARS-CoV-2 dominance period, the median rate of HAV infections was 0.053 per 105, with a four-fold increase being observed from February 2022 (when the migration of war refugees from Ukraine began) to August 2022. The presented results can serve as a reference point for further observations in Central Europe. The HAV epidemiological situation is unlikely to escalate in Poland but requires further monitoring.

RESUMO

This study evaluated the immune response to vaccination against COVID-19 in 534 healthcare frontline workers in Vilnius, Lithuania. The incidence of COVID-19 was reduced significantly after vaccination started in the healthcare sector. SARS-CoV-2 antibodies were detected in groups V-VII and this level of antibodies was found to be effective in preventing COVID-19. Sustained immune response was achieved after two vaccination doses, which remained stable for up to 6 months. After the booster dose, antibody levels remained high for an additional 12 months. Although SARS-CoV-2 antibody levels decreased after 6 months, even lower levels of antibodies provided protection against the Delta strain. The booster dose distributed the antibody titer in the high-level antibody groups, offering maximum protection at 12 months. However, even individuals with high antibody titers were observed to contract COVID-19 after vaccination with a booster dose and 6 months in the presence of the Omicron strain. Unfortunately, high levels of antibodies did not provide protection against the new strain of COVID-19 (the Omicron variant), posing a risk of infection. When comparing the antibody titer of vaccinated participants without COVID-19 and those with COVID-19, the change in antibodies after vaccination was significantly lower in infected participants. Individuals with comorbidities and specific conditions had lower antibody levels.

RESUMO

INTRODUCTION AND OBJECTIVE: Healthcare professionals most often encounter occupational stress. The aim of the study was to investigate the working environment of health care professionals with the focus on expression of occupational stress, and oversee the possibilities of stress management and prevention. MATERIAL AND METHODS: 326 representatives from five different healthcare institutions were surveyed in Siauliai city, Lithuania. The validated questionnaires HSE Management Standards Indicator Tool and the SF-36 questionnaire were used. RESULTS: The study revealed that the most important organizational factors were lack of communication, inappropriate relations with authorities and colleagues, big workload and long working hours, quick decision-making, and manifestations of mobbing. Financial support was reported as one of the main motivators in stress management. The most frequent individual factors were emotional relations with patients and their relatives. The healthcare professionals who experienced stress at work more often felt aches that disturbed their work routine, and their health interfered more their ordinary social activities. The main stress prevention measures are involvement of employees in decision-making, annual interviews with authorities, education, assurance of a safe work environment, and elimination of manifestations of mobbing. CONCLUSIONS: More attention must be paid to occupational stress management. It appeared that there is a lack of knowledge by institutions about the models of occupational stress management and internal stress management policy of organization. Therefore, this stimulates the search for measures that could help to change the situation.

RESUMO

Occupational psychosocial stress can increase the risk of several cardiometabolic diseases. Healthcare workers worldwide experience exceptionally high levels of occupational stress, leading to serious individual, organizational, and societal problems. This narrative review seeks to provide information about the overall consequences of having over-stressed healthcare workers and ascertain how it eventually holds back the advancement of healthcare. In addition, we present a review of the concept, study, and theories related to stress management in order to deeply understand this issue, providing a theoretical perspective of stress management and the subtle concepts of stress, stress management, healthcare structure, and organization in Nigeria. The current literature has shown that Nigerian healthcare workers are more stressed due to long working hours, caregiving responsibilities, and psychological contact with patients. Healthcare workers are more likely to experience stress and burnout than other professions. The level of stress in the healthcare sector has garnered a lot of attention in this regard because of the negative impact of stress on both staff and patients. However, health policies and better working conditions need to be adopted. Collaborative efforts from policymakers, healthcare institutions, and other stakeholders are necessary to prioritize the well-being and productivity of healthcare professionals in the journey toward a more robust and equitable healthcare system.

RESUMO

Aim of the study: To analyze the hepatitis B virus (HBV) infection and mortality in Poland according to sociodemographic characteristics, trends over time, and the impact of the COVID-19 pandemic on hepatitis B epidemiology. Material and methods: We examined HBV infection cases and deaths reported by national registries and used Joinpoint analysis to estimate time trends in the years 2005-2021. To assess the impact of the COVID-19 pandemic on HBV infection, we used monthly information and compared 2020-2022 with 2019. Results: The Joinpoint analysis showed that in Poland between 2005 and 2021, there were pronounced decreasing trends of acute HBV infection, and during the pandemic period, acute HBV infection dramatically decreased (annual percent change, APC2019-2021 for men -57.65%, and women -42.10%, both ptrend < 0.05). There was a fluctuation in trends for chronic HBV infection, shifting from positive to negative in both genders in 2016, and over the pandemic, there were decreasing trends (APC2019-2021 for men -26.94% and women -28.96%, both ptrend < 0.05). From March to July 2022, the value of the diagnosis rate of HBV infection was lower compared to the respective months in 2019, but from September to December 2022, the rate changes were positive. Mortality due to HBV infection decreased in both genders, mainly within the 2005-2019 period. Conclusions: During the COVID-19 pandemic, a sharp decrease in HBV diagnosis rates in Poland, especially in acute cases, was observed. However, trends of hepatitis B infection require further monitoring. It is necessary to introduce a national screening program that also encompasses the population of migrants and improve the linkage to care.

RESUMO

INTRODUCTION: Percentiles of birth weight by gestational age (GA) are an essential tool for clinical assessment and initiating interventions to reduce health risks. Unfortunately, Poland lacks a reference chart for assessing newborn growth based on the national population. This study aimed to establish a national reference range for birth weight percentiles among newborns from singleton deliveries in Poland. Additionally, we sought to compare these percentile charts with the currently used international standards, INTERGROWTH-21 and WHO. MATERIALS AND METHODS: All singleton live births (n = 3,745,239) reported in Poland between 2010 and 2019 were analyzed. Using the Lambda Mu Sigma (LMS) method, the Generalized Additive Models for Location Scale, and Shape (GAMLSS) package, smoothed percentile charts (3-97) covering GA from 23 to 42 weeks were constructed. RESULTS: The mean birth weight of boys was 3453 ± 540 g, and this was higher compared with that of girls (3317 ± 509 g). At each gestational age, boys exhibited higher birth weights than girls. The weight range between the 10th and 90th percentiles was 1061 g for boys and 1016 g for girls. Notably, the birth weight of Polish newborns was higher compared to previously published international growth standards. CONCLUSION: The reference values for birth weight percentiles established in this study for Polish newborns differ from the global standards and are therefore useful for evaluating the growth of newborns within the national population. These findings hold clinical importance in identifying neonates requiring postbirth monitoring.

RESUMO

INTRODUCTION: Limited information is available on trends in hepatitis C virus (HCV) infection, particularly in Central Europe. To address this knowledge gap, we analyzed HCV epidemiology in Poland, considering socio-demographic characteristics, changing patterns over time, and the impact of the COVID-19 pandemic. MATERIAL AND METHODS: We examined HCV cases (diagnosis and deaths) reported by national registries and used joinpoint analysis to estimate time trajectories. RESULTS: Between 2009 and 2021, there were changes in the trends of HCV, shifting from positive to negative in Poland. Among men, there was a significant increase initially in diagnosis rate of HCV in rural areas (annual percent change, APC2009-2016 +11.50%) and urban areas (APC2009-2016 +11.44%) by 2016. In subsequent years until 2019, the trend changed direction, but the reduction was weak (Ptrend > 0.05) in rural areas (-8.66%) and urban areas (-13.63%). During the COVID-19 pandemic, the diagnosis rate of HCV dramatically decreased in rural areas (APC2019-2021 -41.47%) and urban areas (APC2019-2021 -40.88%). Among women, changes in the diagnosis rate of HCV were less pronounced. In rural areas, there was a significant increase (APC2009-2015 +20.53%) followed by no significant change, whereas changes occurred later in urban areas (APC2017-2021 -33.58%). Trend changes in total mortality due to HCV were mainly among men, with a significant decrease in rural (-17.17%) and urban (-21.55%) areas from 2014/2015. CONCLUSIONS: The COVID-19 pandemic reduced HCV diagnosis rates in Poland, especially for diagnosed cases. However, further monitoring of HCV trends is necessary, along with national screening programs and improved linkage to care.

RESUMO

BACKGROUND: Air pollution is a major risk factor for public health worldwide, but evidence linking this environmental problem with the mortality of children in Central Europe is limited. OBJECTIVE: To investigate the relationship between air pollution due to the emission of industry-related particulate matter and mortality due to respiratory diseases under one year of age. METHODS: A retrospective birth cohort analysis of the dataset including 2,277,585 children from all Polish counties was conducted, and the dataset was matched with 248 deaths from respiratory diseases under one year of age. Time to death during the first 365 days of life was used as a dependent variable. Harmful emission was described as total particle pollution (TPP) from industries. The survival analysis was performed using the Cox proportional hazards model for the emission of TPP at the place of residence of the mother and child, adjusted individual characteristics, demographic factors, and socioeconomic status related to the contextual level. RESULTS: Infants born in areas with extremely high emission of TPP had a significantly higher risk of mortality due to respiratory diseases: hazard ratio (HR) = 1.781 [95% confidence interval (CI): 1.175, 2.697], p = 0.006, compared with those born in areas with the lowest emission levels. This effect was persistent when significant factors were adjusted at individual and contextual levels (HR = 1.959 [95% CI: 1.058, 3.628], p = 0.032). The increased risk of mortality was marked between the 50th and 150th days of life, coinciding with the highest exposure to TPP. CONCLUSIONS: The emission of TPP from industries is associated with mortality due to respiratory diseases under one year of age. A considerable proportion of children's deaths could be prevented in Poland, especially in urban areas, if air pollution due to the emission of particle pollution is reduced.

RESUMO

Small for gestational age (SGA) births are a significant clinical and public health issue. The objective of this review was to summarize maternal biological and socio-demographic factors and preventive strategies used to reduce the risk of SGA births. A literature search encompassing data from the last 15 years was conducted using electronic databases MEDLINE/PubMed, Google Scholar and Scopus to review risk factors and preventive strategies for SGA. Current evidence shows that primiparity, previous stillbirths, maternal age ≤24 and ≥35 years, single motherhood, low socio-economic status, smoking and cannabis use during pregnancy confer a significant risk of SGA births. Studies on alcohol consumption during pregnancy and SGA birth weight are inconclusive. Beneficial and preventive factors include the "Mediterranean diet" and dietary intake of vegetables. Periconceptional folic acid supplementation, maternal 25-hydroxyvitamin D, zinc and iron levels are partly associated with birth weight. No significant associations between COVID-19 vaccinations and birthweight are reported. A midwifery-led model based on early and extensive prenatal care reduces the risk of SGA births in women with low socio-economic status. Major preventive measures relate to the awareness of modifiable and non-modifiable risk factors of SGA, leading to changes in parents' lifestyles. These data support that education, monitoring during pregnancy, and implementing preventive strategies are as important as biological determinants in risk reduction of SGA births.

RESUMO

Due to the multifactorial etiology of scoliosis, a comprehensive treatment plan is essential for conservative management. Physiotherapeutic scoliosis-specific exercise (PSSE) methods have lately gained popularity for the conservative treatment of scoliosis. The aim of this study was to analyze the PSSE methodologies used for conservative treatment of adolescent idiopathic scoliosis (AIS), as well as their effectiveness. The study was based on an extended literature search conducted in the PubMed, Google Scholar, PEDro, eLABA, and BioMed Central databases. A total of 123 articles were selected for this study (including articles overviewed in systematic reviews and meta-analyses) after applying the inclusion criteria. The study revealed that inappropriate management of AIS could result in serious health problems. Conservative interventions that aid in stabilizing spine curvature and improving esthetics are preferred for scoliosis treatment. Bracing has traditionally been the mainstay of treatment, but growing evidence suggests that PSSE physiotherapy allows effective management of idiopathic adolescent scoliosis. Currently, there are the following PSSE physiotherapy schools in Europe: Schroth, SEAS, BSPTS, FED, FITS, Lyon, Side Shift, and DoboMed. The methodologies of these schools are similar, in that they focus on applying corrective exercises in three planes, developing stability and balance, breathing exercises, and posture awareness. Although high-quality research supporting the effectiveness of PSSE physiotherapy in the treatment of AIS is lacking, existing evidence indicates that PSSE physiotherapy helps to stabilize spinal deformity and improve patients' quality of life. Among the abovementioned methodologies, Schroth is the most widely studied and has been proven to be effective. However, both SEAS and BSPTS effectively stabilize and even reduce the Cobb angle of scoliosis. Data supporting the validity of other methodologies are very limited. Only the Schroth method significantly reduces the angle of trunk rotation, while both SEAS and Schroth methods greatly improve the quality of life indicators. In any case, the available evidence is insufficient to confirm the advantage of one specific physiotherapy technique over others.

RESUMO

OBJECTIVES: The eating habits of most Lithuanian people do not adhere to the recommendations for a healthy diet. If children and adolescents were provided with the relevant information, it would not only improve their nutritional knowledge, but also their eating habits in adulthood and the subsequent health of their children. The objective of this study was to determine the need for information on nutrition among Lithuanian adolescents, the current knowledge of adults regarding recommendations for the consumption of various food groups, and the factors that influence both the need for information and the current knowledge. METHODS: Two cross-sectional studies were conducted, consisting of 3,574 adolescents aged 14-18 years and 1,007 adults aged 18-75 years. Logistic regression models with confidence intervals of 95% were used to determine the influence of various socio-demographic factors on the adolescent need for information on nutrition and the adult knowledge of nutrition. RESULTS: A total of 66.7% of adolescents stated that they need information regarding nutrition, whereas 29.8% indicated that they lack such information. Significantly more girls than boys, and more students from schools in urban areas than students from schools in rural areas, expressed their need for information on nutrition. Lithuanian adults lacked knowledge of recommendations for the consumption of various food groups. Women and respondents with higher education degrees were found to have more knowledge on recommendations of the consumption of various food groups compared to men and respondents of other levels of education respectively. CONCLUSIONS: The results of this study demonstrate that the required information on nutrition must be continuously provided via various channels to both adolescents and adults, and socio-demographic factors must be taken into account when planning public health intervention measures.

RESUMO

BACKGROUND: Information about trends in perinatal and child health inequalities is scarce, especially in the Eastern Europe. We analyzed how mortality under 1 year of age has been changing in the Baltic States and the European Union (EU) over 25 years, and what associations occurred between changes in macroeconomic factors and mortality. METHODS: Data on fetal, neonatal, infant mortality, and macroeconomic factors were extracted from WHO database. Joinpoint regression analysis was performed to analyze time trajectories of mortality over 1990-2014. We also investigated how the changes in health expenditures and Gross Domestic Product (GDP) contributed to the changes in mortality. RESULTS: The reduction of fetal, neonatal and infant mortality in the Baltic countries led to convergence with the EU. In Estonia this process was the fastest, and then the rates tended to diverge. The strongest effect in reduction of neonatal mortality was related to the annual increase in health expenditure and GDP which had occurred in the same year, and a decrease in fetal mortality associated with an increase in health expenditure and GDP in the 4th and 5th year, respectively, following the initial change. CONCLUSIONS: These findings outlined convergences and divergences in mortality under 1 year of age in the Baltic States compared with the patterns of the EU. Our data highlighted a need to define health policy directions aimed at the implementation of effective intervention modalities addressing reduction of risks in prenatal and early life.

RESUMO

OBJECTIVES: The availability of information on healthy products does not ensure the empowerment of people with the knowledge on how to choose or avoid food products or dishes depending on unhealthy factors. Public knowledge and beliefs of unhealthy food effects on health needs to be evaluated so that appropriate measures can be taken to properly inform people and relevant socio-demographic groups. METHODS: The original survey questionnaire containing questions about specific food groups and various health effects was compiled. A total of 1,007 respondents, Lithuanian residents aged 18-75 years, were surveyed in March 2019. Multilevel stratified probability sampling method was used for data representativeness. RESULTS: Almost half of respondents (46.2%) knew that deep-fried food could cause cancer. The majority of respondents (68.4%) were aware that sugar causes obesity and 61.7% were aware that sugar increases the risk of diabetes mellitus; 41.6% (more often those living in non-rural areas) know that grilled meat may cause cancer. More than half of respondents (57.2%) (more likely those living in non-rural areas and those with a university degree) were aware that smoked meat products may cause cancer. Only 46.4% were aware of the fact that salt raises blood pressure and the risk of cardiovascular diseases. CONCLUSION: Only about half of Lithuanian residents aged 18-75 were aware of the scientifically proven harmful effects of unhealthy food groups. Socio-demographic factors influence the knowledge and beliefs of the population.

RESUMO

During the last two decades, the number of macrocell mobile telephony base station antennas emitting radiofrequency (RF) electromagnetic radiation (EMR) in residential areas has increased significantly, and therefore much more attention is being paid to RF EMR and its effects on human health. Scientific field measurements of public exposure to RF EMR (specifically to radio frequency radiation) from macrocell mobile telephony base station antennas and RF electromagnetic field (EMF) intensity parameters in the environment are discussed in this article. The research methodology is applied according to the requirements of safety norms and Lithuanian Standards in English (LST EN). The article presents and analyses RF EMFs generated by mobile telephony base station antennas in areas accessible to the general public. Measurements of the RF electric field strength and RF EMF power density were conducted in the near- and far-fields of the mobile telephony base station antenna. Broadband and frequency-selective measurements were performed outside (on the roof and on the ground) and in a residential area. The tests performed on the roof in front of the mobile telephony base station antennas in the near-field revealed the presence of a dynamic energy interaction within the antenna electric field, which changes rapidly with distance. The RF EMF power density values on the ground at distances of 50, 100, 200, 300, 400, and 500 m from the base station are very low and are scattered within intervals of 0.002 to 0.05 µW/cm². The results were compared with international exposure guidelines (ICNIRP).

RESUMO

BACKGROUND/AIM: The aim was to assess the differences between physical activity and physical fitness in obese, overweight, and normal-weight children. MATERIALS AND METHODS: The cross-sectional study was accomplished using cluster sampling method at 3 Lithuanian schools. An analysis of anthropometric data for 532 Lithuanian children was performed. Height, weight, waist and hip circumferences, and skinfold thickness were measured. Body mass index, waist-to-hip ratio, and body fat percentage were calculated. The Youth Physical Activity Questionnaire and a 6-min walk test (6MWT) were administered to evaluate physical activity and physical fitness. Maximal oxygen consumption was calculated to assess the children's aerobic capacity. Correlations among anthropometric data, 6MWT-walked distance, and moderate-vigorous physical activity duration were analyzed. RESULTS: The study showed that 20.1% of the studied children were obese or overweight. They engaged in moderate-to-vigorous physical activity 22.4 min less per day and walked 50.9 m less on average during a 6-min test than normal-weight children. Physical fitness parameters correlated with daily moderate-vigorous physical activity duration and with most of the children's anthropometric parameters. CONCLUSION: Obese and overweight children were less physically active and had lower physical fitness than normal-weight children. The findings underline the need for interventions to increase physical activity and improve fitness in obese and overweight children.

RESUMO

BACKGROUND/AIM: Electromagnetic field exposure is the one of the most important physical agents that actively affects live organisms and environment. Active use of mobile phones influences the increase of electromagnetic field radiation. The aim of the study was to measure and assess the electric field strength caused by mobile phones to the human head. METHODS: In this paper the software "COMSOL Multiphysics" was used to establish the electric field strength created by mobile phones around the head. RESULTS: The second generation (2G) Global System for Mobile (GSM) phones that operate in the frequency band of 900 MHz and reach the power of 2 W have a stronger electric field than (2G) GSM mobile phones that operate in the higher frequency band of 1,800 MHz and reach the power up to 1 W during conversation. The third generation of (3G) UMTS smart phones that effectively use high (2,100 MHz) radio frequency band emit the smallest electric field strength values during conversation. The highest electric field strength created by mobile phones is around the ear, i.e. the mobile phone location. The strength of mobile phone electric field on the phantom head decreases exponentially while moving sidewards from the center of the effect zone (the ear), and constitutes 1-12% of the artificial head's surface. CONCLUSION: The highest electric field strength values of mobile phones are associated with their higher power, bigger specific energy absorption rate (SAR) and lower frequency of mobile phone. The stronger electric field emitted by the more powerful mobile phones takes a higher percentage of the head surface. The highest electric field strength created by mobile phones is distributed over the user's ear.

RESUMO

AIM: To assess the relationship of children's physical activity and sedentary screen time with overweight and obesity in children living in different environments (town and city) in Lithuania. METHODS: An analysis of anthropometric data from 532 children living in town and city areas was performed. A youth physical activity questionnaire (YPAQ) was conducted to evaluate physical activity and sedentary screen time. RESULTS: The prevalence of overweight and obesity among the children was 25.5% in the town and 18.6% in the city. Children living in the town on average engaged 9.3 min/day less in moderate to vigorous physical activity (p=0.050) and had 33.2 MET-min/day lower energy expenditure than children living in the city. Sedentary screen time was extremely high on weekends in both town and city children.

RESUMO

BACKGROUND AND OBJECTIVE: Cannabis use is widespread among young people in Europe. The aim of this study was to analyze and to compare the associations between the self-reported consumption of cannabis products and other illicit drugs among older schoolchildren in 2006 and in 2012. MATERIALS AND METHODS: Two cross-sectional surveys were conducted in 2006 and 2012 in Northern Lithuania. In total 3447 young people aged 17-19 years were investigated (1585 male and 1862 female). For this survey, the ESPAD questionnaire was used. RESULTS: In Northern Lithuania, the schoolchildren aged 17-19 years self-reported that 16.7% in 2006 and 23.9% in 2012 of them tried cannabis products. The consumption of cannabis products in the age group of 17 years increased from 14.9% in 2006 to 21.5% in 2012. The consumption of cannabis together with alcohol increased from 7.6% to 14.3%. Cannabis consumers more often tried amphetamines, heroin, LSD, cocaine, crack, ecstasy, hallucinogenic mushrooms, and injective drugs. In 2012, cannabis consumers girls less than boys used only crack and injective drugs; all other illicit drugs they used the same often as boys. CONCLUSIONS: The cannabis products consumption in schoolchildren has increased by 7%. Nearly twofold increase was observed in the consumption of cannabis together with alcohol. Young people who used cannabis products more often tried other illicit drugs. There were no differences by gender in the consumption of illicit drugs among cannabis consumers.

RESUMO

This study analyzes traffic mortality trends among road users from 1998 to 2012 in children and adolescents aged 0-19 years in Lithuania. National mortality data of pedestrians, cyclists, motorcyclists, and car occupants were used to compare trend lines. The study revealed that 56% of the deceased in road traffic crashes were car occupants, while 24% were pedestrians. The incidence of death from traffic injury was 2.5 times higher in boys than girls. Traffic injury mortality and pedestrian mortality rates declined significantly in the total group. There was also a significant decline in mortality among cyclists for the total group and female subgroup. Trends in mortality rates among motorcyclists and car occupants showed no significant changes. A long-term decline is more likely to be affected by efforts in the promotion of sustainable and permanent road safety. The reduced risk exposure may also have been influenced by the economic recession.
