Objective: To analyze trends in external mortality in Hungary between 1995 and 2014 by sex. Methods: Data on the numbers of deaths due to external causes were obtained from the published nationwide population register. Negative binomial regression was applied to investigate the yearly trends in external-cause mortality rates. Cyclic trends were investigated using the Walter-Elwood method. Results: Suicide and accidents accounted for approximately 84% of the all-external-cause of deaths in Hungary. Annual suicide, unintentional falls and traffic accidents mortality declined significantly (p-value for annual trend: p < 0.001) from 30.5 (95% CI: 29.5–31.5) to 15.8 (15.1–16.5), from 31.2 (30.2–32.2) to 12.2 (11.7–12.8) and from 17.2 (16.4–18) to 5.4 (5–5.8) per 100 000 persons per year, respectively, during the study period. A significant declining trend in annual mortality was also found for assault, cold/heating-related accidents and accidents caused by electric current. However, the declining trend for drowning-related accidents was significant only for males. Significant winter-peak seasonality was found in the mortality rates from accidental falls, cold/heat-related accidents, other accidents caused by submersion/obstruction and other causes. Seasonal trends with a peak from June to July were observed in death rates from suicide/self-harm, accidental drowning/submersion and accidents caused by electric current. A significant seasonal variation with a peak in September was revealed in the mortality due to traffic accidents. Conclusions: This Hungarian study suggests that there was a significant seasonal effect on almost all kinds of deaths from external causes between 1995 and 2014. Environmental effects are involved in the aetiology of suicide and accidents. [ABSTRACT FROM AUTHOR]

Aim: This study investigated annual and seasonal death trends for infants of <1 year of age in Hungary between 1963 and 2012 and analysed commonly accepted risk factors. Methods: Data on the numbers of live births and infant deaths were obtained from the published nationwide population register. Negative binomial regression was applied to investigate the yearly trends in rates and also the effect of possible risk factors - low birthweight, maternal education and sex - on infant mortality. Cyclic trends were investigated using logistic regression. Results: Annual infant mortality declined significantly (p<0.001) from 42.9 to 4.9 per 1000 live births per year during the study period and significantly increased (p<0.001) in the low birthweight group and lower maternal education groups. A significant (p<0.001) cyclic trend in mortality was revealed, with a peak in deaths in late February for all infants and a double peak, in May and November, in the group of cases who died during the early neonatal period. Conclusion: This Hungarian study suggests that there was a significant seasonal effect on neonatal and infant mortality at the end of winter between 1963 and 2012. We speculate that this may have been related to respiratory infections. [ABSTRACT FROM AUTHOR]

Objective: This study investigated annual and seasonal trends in deaths for cancers of the female genital organs and breast in Hungary between 1979 and 2013., Study Design: Data on the numbers of cancer deaths were obtained from the published nationwide population register. Joinpoint regression was applied to investigate the yearly trends in cancer mortality rates. Cyclic trends were investigated using logistic regression, Edwards' and Walter-Elwood methods., Results: The majority of deaths from cancers of the female genital organs and breast occurred in winter but using the observed numbers of deaths a significant seasonal pattern was only revealed for deaths from breast cancer with a peak in January and a nadir in July. However, seasonality in the proportion of deaths from female genital organs and breast cancers out of deaths from all causes detected a different peak and nadir. The proportion of female genital organs and breast cancer deaths out of deaths from all causes was higher around the end of summer and significant seasonal variation with a peak in August and nadir in February was revealed., Conclusion: This Hungarian study suggests that there was a significant seasonal effect on female genital organs and breast cancer mortality. Both seasonal patterns are interesting and informative to potentiate prevention. Our findings suggest that infectious diseases may increase the risk of the mortality among the immune deficient patents., (Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.)

Our aim was to investigate the ecological association between death from infectious disease of the respiratory system and the risk of acute lymphoid leukaemia (ALL) in children aged less than 7 years. Poisson regression analyses were carried out using overall data and gender-specific models. The study included 176 cases (92(52.3 %) boys and 84 (47.7 %) girls) of ALL in those aged 0-6 years in South Hungary. Eight cases were diagnosed before the age of 1 year. A significant risk of ALL disease was observed with higher levels of mortality from the chronic respiratory diseases (p = 0.035) and pneumonia (p = 0.010) among children aged 2-5 years (Odds Ratio for trend was 1.001 and 95%CI [1.000-1.002] and Odds ratio for trend was 1.013 and 95%CI [1.003-1.023], respectively). Significantly increased risk of childhood ALL was detected among children under 1 year of age residing in areas around birth with higher levels of mortality from influenza (Odds Ratio (OR) for trend was 1.05; 95%CI [1.01-1.09]; p = 0.012). This risk was also detected in girls (p < 0.001), but not in boys (p = 0.43). Our findings provide new evidence that will help to understand the different pattern of female and male childhood ALL occurrence , but further studies are needed using detailed individual medical history to clarify the role of influenza and other infectious diseases in the etiology of childhood ALL and to explain gender-specific effects.
