Barriers and facilitators to sexual and reproductive health services among adolescents and young adults in Sidama region, Ethiopia
Spatial patterns of environmental injustice in social vulnerability and ambient dust levels across Australia
Ambient dust exposure has been associated with several adverse health outcomes. Unlike ambient air pollution, the vulnerability of subpopulations to ambient dust has not yet been explored. As the driest inhabited continent, Australia provides a natural laboratory for studying large-scale dust exposure. This study aimed to examine environmental injustice in the ambient dust of ⩽10 μ m particle size and vulnerability of subpopulations in Australia,…
Indirect evidence of sex-selective abortion practices to the imbalanced sex ratio at birth in Australian migrant populations
A skewed sex ratio at birth (SRB), commonly observed in countries with high son preference can be attributed to prenatal sex-selective abortion. However, the possibility of sex selection among migrants in high-income countries has received little attention. Our study aims to identify the indirect evidence of sex-selective abortion practices to the SRB imbalance in a large Australian cohort. Our study aims to identify the indirect evidence of sex-…
Trends in adverse perinatal outcomes and associated hospitalisations, emergency department presentations, and healthcare costs from birth to early childhood in the Northern Territory, Australia
Adverse perinatal outcomes, including preterm birth (PTB), small-for-gestational-age (SGA), and low birthweight (LBW), impact childhood health and impose substantial burdens. This retrospective cohort study included all births in the Northern Territory, Australia, from July 1, 2000, to June 30, 2016, examining trends in these outcomes and related hospitalisations, emergency department (ED) presentations, and healthcare costs through June 30, 2021…
Extreme drought and sexual violence against adolescent girls and young women
Droughts have profound and far-reaching impacts on human health and well-being, but their influence on sexual violence among adolescent girls in low- and middle-income countries (LMICs) is underexamined.This study examines the association between drought and sexual violence against adolescent girls and young women globally, using cross-sectional, nationally representative data from the Violence Against Children and Youth Surveys (VACS) from 2013 …
Knowledge, attitude, and practice of One Health and zoonotic diseases among multisectoral collaborators in Bhutan
The One Health concept is increasingly employed to combat zoonotic diseases. This study assessed the knowledge, attitudes, and practices regarding One Health and zoonotic diseases among key sector professionals to identify gaps and opportunities for enhancing One Health strategies in Bhutan. A cross-sectional, facility-based study was used to conduct a nationwide online questionnaire survey using a validated and pre-tested questionnaire among pro…
Adolescents and young adults' preferences for sexual and reproductive health services in Ethiopia
Privacy and service quality emerged as the most important attributes influencing the uptake of SRH services among AYAs. However, there is preference heterogeneity among sociodemographic groups, underscoring the need for context-specific interventions
Global fertility in 204 countries and territories, 1950–2021, with forecasts to 2100
BACKGROUND: Accurate assessments of current and future fertility-including overall trends and changing population age structures across countries and regions-are essential to help plan for the profound social, economic, environmental, and geopolitical challenges that these changes will bring. Estimates and projections of fertility are necessary to inform policies involving resource and health-care needs, labour supply, education, gender equality,…
Global age-sex-specific mortality, life expectancy, and population estimates in 204 countries and territories and 811 subnational locations, 1950–2021, and the impact of the Covid-19 pandemic
BACKGROUND: Estimates of demographic metrics are crucial to assess levels and trends of population health outcomes. The profound impact of the COVID-19 pandemic on populations worldwide has underscored the need for timely estimates to understand this unprecedented event within the context of long-term population health trends. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 provides new demographic estimates for 204 cou…
Risk factors of under-five and infant mortality
The hidden impact of alcohol on young victims
There is a noteworthy disparity between the quantity of hospital admissions attributed to alcohol-related incidents and the number of cases that are formally classified as ARH in the hospital system. This disparity highlights a more profound issue of substantial under-ascertainment or inadequate identification of ARH than previously acknowledged. Our findings justify the prioritisation of prevention strategies, beyond improvement in the documenta…
National and subnational burden of under-5, infant, and neonatal mortality in Ethiopia, 1990–2019
The under-5 mortality rate is a commonly used indicator of population health and socioeconomic status worldwide. However, as in most low- and middle-income countries settings, deaths among children under-5 and in any age group in Ethiopia remain underreported and fragmented. We aimed to systematically estimate neonatal, infant, and under-5 mortality trends, identify underlying causes, and make subnational (regional and chartered cities) compariso…
Changes in preterm birth and stillbirth during Covid-19 lockdowns in 26 countries
Preterm birth (PTB) is the leading cause of infant mortality worldwide. Changes in PTB rates, ranging from −90% to +30%, were reported in many countries following early COVID-19 pandemic response measures ('lockdowns'). It is unclear whether this variation reflects real differences in lockdown impacts, or perhaps differences in stillbirth rates and/or study designs. Here we present interrupted time series and meta-analyses using harmonized data f…
Young people with prior health service contacts have increased risk of repeated alcohol‐related harm hospitalisations
Lived experiences of women with low birth weight infants in the Solomon Islands
Every year, around 20 million women worldwide give birth to low birth weight (LBW) infants, with majority of these births occurring in low-and middle-income countries, including the Solomon Islands. Few studies have explored the pregnancy lived experience of women who deliver LBW infants. The aim of the study is to understand the lived experience of women in the Solomon Islands who gave birth to LBW infants by exploring their personal (socio-demo…
The role of family planning counselling during maternal and child health services in postpartum modern contraceptive uptake in Ethiopia
Family planning counselling can help improve the postpartum modern contraceptive uptake. However, studies in Ethiopia indicate inconsistent effects of integrated family planning counselling on postpartum modern contraceptive uptake. This study aimed to determine the extent of family planning counselling and its role in improving postpartum contraceptive uptake among women in Ethiopia. We used the Performance Monitoring for Action (PMA) Ethiopia p…
Diabetic and Hypertensive Disorders Following Miscarriage
(1) Background: Miscarriages occur in approximately 15-25% of all pregnancies. There is limited evidence suggesting an association between history of miscarriage and the development of diabetic and hypertensive disorders in women. This systematic review aims to collate the existing literature and provide up to date epidemiological evidence on the topic. (2) Methods: We will search CINAHL Plus, Ovid/EMBASE, Ovid/MEDLINE, ProQuest, PubMed, Scopus, …
Trends and burden of diabetes in pregnancy among Aboriginal and non-Aboriginal mothers in Western Australia, 1998–2015
There has been a substantial increase in the burden of pre-gestational diabetes (Aboriginal women) and gestational diabetes (Aboriginal and non-Aboriginal) in recent decades. DIP appears to substantially contribute to increasing trends in LGA among Aboriginal babies
Energy transitions, air quality and health
The way we produce and use energy is transforming. Policy in this area intersects decisions that affect climate change, air quality, and the economy. The exponential increase in use of fossil fuel and nuclear energy has now essentially replaced human and animal energy (McKinney 2019 Curr. Pollut. Rep. 5 394–406; Solomon and Krishna 2011 Energy Policy 39 7422–31). These transitions have contributed to notable gains, such as improvements in mortali…
Avoidable Mortality Attributable to Anthropogenic Fine Particulate Matter (PM2.5) in Australia
Ambient fine particulate matter 2.5 ) air pollution increases premature mortality globally. Some PM 2.5 is natural, but anthropogenic PM 2.5 is comparatively avoidable. We determined the impact of long-term exposures to the anthropogenic PM component on mortality in Australia. PM 2.5 -attributable deaths were calculated for all Australian Statistical Area 2 (SA2; n = 2310) regions. All-cause death rates from Australian mortality and population da…
Ambient Air Pollution, Extreme Temperatures and Birth Outcomes
Prenatal exposure to ambient air pollution and extreme temperatures are among the major risk factors of adverse birth outcomes and with potential long-term effects during the life course. Although low- and middle-income countries (LMICs) are most vulnerable, there is limited synthesis of evidence in such settings. This document describes a protocol for both an umbrella review (Systematic Review 1) and a focused systematic review and meta-analysis…
Prevalence and Predictors of Vitamin D Deficiency among African Immigrants Living in Australia
Vitamin D deficiency (serum 25-hydroxyvitamin D (25(OH)D) concentrations n = 236). Serum 25(OH)D was measured using a liquid chromatography-tandem mass spectrometry method that is certified to international reference measurement procedures. Poisson regression was used to investigate independent predictors of vitamin D deficiency. A total of 36% of adults were vitamin D deficient (35% of men, 37% of women). The prevalence ratio (PR) of vitamin D d…
The Contribution of Geogenic Particulate Matter to Lung Disease in Indigenous Children
Indigenous children have much higher rates of ear and lung disease than non-Indigenous children, which may be related to exposure to high levels of geogenic (earth-derived) particulate matter (PM). The aim of this study was to assess the relationship between dust levels and health in Indigenous children in Western Australia (W.A.). Data were from a population-based sample of 1077 Indigenous children living in 66 remote communities of W.A. (>2,000…
Geo-visual integration of health outcomes and risk factors using excess risk and conditioned choropleth maps
Ghana remains malaria hyperendemic region with district-level spatial heterogeneity. Significant association between malaria and sociodemographics was detected and the ERMs and CCMs geo-visually pinpointed locations of these significant associations. To complement sophisticated spatial regression models, the easily interpretable ERMs and CCMs could be used to specify where disease-risk factor associations are significant, simplifying complex spat…

Spatial and temporal variation in type 1 diabetes incidence in Western Australia from 1991 to 2010
Association between pre-eclampsia and locally derived traffic-related air pollution
BACKGROUND: Pre-eclampsia is a common complication of pregnancy and is a major cause of fetal-maternal mortality and morbidity. Despite a number of plausible mechanisms by which air pollutants might contribute to this process, few studies have investigated the association between pre-eclampsia and traffic emissions, a major contributor to air pollution in urban areas. OBJECTIVE: The authors investigated the association between traffic-related air…

The association between neighborhood greenness and cardiovascular disease
Variability in neighborhood greenness is a single metric that encapsulates two potential promoters of physical activity - an aesthetically pleasing natural environment and access to urban destinations. Variability in greenness within a neighborhood was negatively associated with coronary heart disease and stroke
Neighborhood walkability and cardiometabolic risk factors in australian adults
A protective association between neighborhood walkability and obesity was observed. Neighborhood walkability may also be protective of type-2 diabetes mellitus, particularly in men. No association with hypertension or hypercholesterolaemia was found. This warrants further investigation. Findings contribute towards the accumulating evidence that city planning and policy related strategies aimed at creating supportive environments could play an imp…
