Sex Ratio at Birth in Northern Ireland During the Covid ‐19 Pandemic
OBJECTIVES: The COVID-19 pandemic has been linked in several countries to fluctuations in the proportion of male live births/total live births, known as the sex ratio at birth (SRB). This study investigates how the pandemic influenced SRB patterns in Northern Ireland compared to published data from neighboring regions, including the Republic of Ireland with which it shares an open land border, and England and Wales, across the sea. METHODS: Month…
The Impact of the Covid ‐19 Pandemic on the Sex Ratio at Birth in Ireland
OBJECTIVES: The sex ratio at birth (SRB), calculated as male divided by total live births, is an important indicator of population health. Typically, male live births slightly outnumber female live births. Population events, including pandemics, can alter the SRB, with effects sometimes evident 9 months post-event, potentially due to changes in sexual behavior and/or stress levels. This study investigates the impact of the COVID-19 pandemic on th…
A population-based paediatric Covid-19 vaccination progress and outcomes
Assessing the impact of the four Covid-19 variants and the vaccine coverage on mortality in Malta over 2 years
Background: Mortality may quantify a population's disease burden. Malta, like other European countries, experienced COVID-19 surges in cases and mortality across the pandemic. This study assesses COVID-19's mortality impact, while exploring the effects of the four dominant COVID-19 variants and that of the vaccination coverage on the Maltese population. Methods: COVID-19 data (cases, mortality, positivity, and vaccination rates) was obtained from…
Mass Events Trigger Malta's Second Peak After Initial Successful Pandemic Suppression
Maternal Educational Attainment and Sex Ratio at Birth by Race in the United States, 2007–2015
Many factors influence the male:female birth ratio (number of male births divided by total births, M/T). Studies have suggested that this ratio may be positively correlated with the education levels of mothers. This study assessed the effect of maternal education on M/T in the US population overall and by racial group. Number of live births by sex of the child, maternal educational level reached and race were obtained from the Centres for Disease…
Effects of Stressful Events in France (1968) and Japan (1995) on the Sex Ratio at Birth
Males are usually born in excess of females. The sex ratio at birth (SR) is often expressed as the ratio of male to total births. A wide variety of factors have been shown to influence SR, including terrorist attacks, which have been shown to reduce SR. This paper reviews the effects on SR outcomes of the stressful events in France in 1968 (in association with the student and worker riots) and in Japan following the Aum Shinrikyo religious cult’s…
Seasonality of Births Is Associated With Seasonality of Marriages in Malta
This study was carried out to quantify secular trends in seasonal variation in births in Malta, a small Mediterranean country where the vast proportion of births occur in wedlock due to a predominantly Roman Catholic population. It also related such variations to seasonal variation in marriages. Annual seasonal peaks of marriages and births were analysed over the period 1950–1996 by X11 ARIMA. A significant peak in marriages ( n =111,932) in the …
Secular trends in sex ratios at birth in North America and Europe over the second half of the 20th century
Context: A previous study showed that significantly more boys were born in southern latitudes in Europe than in northern latitudes and the converse pattern was observed in North America. Objective: This study analyses secular trends in gender ratios for live births over the second half of the 20th century. Design, setting, participants: Analysis was carried out from a World Health Organisation dataset comprising live births over the above period.…
Gender differences in seasonality of acute myocardial infarction admissions and mortality in a population-based study
Gender diVerences in seasonality of acute myocardial infarction admissions and mortality in a population-based study V Grech, O Aquilina, J Pace Acute myocardial infarction (AMI) causes significant morbidity and mortality, and accounts for a substantial proportion of healthcare appropriation.Several studies have shown a seasonal variation in onset and mortality from AMI.Such variations are important not only for epidemiological purposes, but also…
Declining male births with increasing geographical latitude in Europe
OBJECTIVE: Demographic studies in various industrialised countries have shown a decline in male births in the latter half of the 20th century from the expected ratio of 0.515 (males/total). This study analyses trends in this ratio over the period 1890 to 1995 in Malta, and also analyses this ratio for Western European countries for the period 1990-1995. DESIGN: Births subdivided by sex were obtained from official Maltese publications. European co…
An excess of tetralogy of Fallot in Malta
STUDY OBJECTIVE: To estimate birth prevalence of tetralogy of Fallot (TF) in Malta. DESIGN: Retrospective data collection and analysis, and comparison with earlier epidemiological studies dealing with congenital heart disease. SETTING: Regional hospital providing exclusive diagnostic and follow up services for the entire country of Malta. PATIENTS: All Maltese live births diagnosed as having TF. MAIN RESULTS: The birth prevalence of TF in Malta f…
