Strategies and indicators to integrate health equity in health service and delivery systems in high-income countries: a scoping review.

OBJECTIVE: The objective of this review was to describe how health service and delivery systems in high-income countries define and operationalize health equity. A secondary objective is to identify implementation strategies and indicators being used to integrate and measure health equity. INTRODUCTION: To improve the health of populations, a population health and health equity approach is needed. To date, most work on health equity integration has focused on reducing health inequities within public health, health care delivery, or providers within a health system, but less is known about integration across the health service and delivery system. INCLUSION CRITERIA: This review included academic and gray literature sources that described the definitions, frameworks, level of integration, strategies, and indicators that health service and delivery systems in high-income countries have used to describe, integrate, and/or measure health equity. Sources were excluded if they were not available in English (or a translation was not available), were published before 1986, focused on strategies that were not implemented, did not provide health equity indicators, or featured strategies that were implemented outside the health service or delivery systems (eg, community-based strategies). METHODS: This review was conducted in accordance with the JBI methodology for scoping reviews. Titles and abstracts were assessed followed by a full-text review. The information extracted consisted of study design and key findings, such as health equity definitions, strategies, frameworks, level of integration, and indicators. Most data have been quantitatively tabulated and presented according to 5 review questions. Some findings (eg, definitions and indicators) were summarized using qualitative methods. Most findings are visually presented in charts and diagrams or presented in tabular format. RESULTS: Following review of 16,297 titles and abstracts and 824 full-text sources, we included 122 sources (113 peer-reviewed, 9 gray literature) in this scoping review. We found that health equity was inconsistently defined and operationalized. Only 17 sources included definitions of health equity and we found that both indicators and strategies were lacking adequate descriptions. The use of health equity frameworks was limited and, where present, there was little consistency or agreement in their use. We found that strategies were often specific to programs, services, or clinics, rather than broadly applied across health service and delivery systems. CONCLUSIONS: Our findings suggest that strategies to advance health equity work are siloed within health service and delivery systems and are not currently being implemented system-wide (ie, across all health settings). Healthy equity definitions and frameworks are varied in the included sources, and indicators for health equity are variable and inconsistently measured. Health equity integration needs to be prioritized within and across health service and delivery systems. There is also a need for system-wide strategies to promote health equity, alongside robust accountability mechanisms for measuring health equity. This is necessary to ensure that an integrated, whole-system approach can be consistently applied in health service and delivery systems internationally.

The Hidden Toll of Psychological Distress in Australian Adults and Its Impact on Health-Related Quality of Life Measured as Health State Utilities.

BACKGROUND: Psychological distress (PD) is a major health problem that affects all aspects of health-related quality of life including physical, mental and social health, leading to a substantial human and economic burden. Studies have revealed a concerning rise in the prevalence of PD and various mental health conditions among Australians, particularly in female individuals. There is a scarcity of studies that estimate health state utilities (HSUs), which reflect the overall health-related quality of life in individuals with PD. No such studies have been conducted in Australia thus far. OBJECTIVE: We aimed to evaluate the age-specific, sex-specific and PD category-specific HSUs (disutilities) in Australian adults with PD to inform healthcare decision making in the management of PD. METHODS: Data on age, sex, SF-36/SF6D responses, Kessler psychological distress (K10) scale scores and other characteristics of N = 15,139 participants (n = 8149 female individuals) aged >15 years were derived from the latest wave (21) of the nationally representative Household, Income and Labor Dynamics in Australia survey. Participants were grouped into the severity categories of no (K10 score: 10-19), mild (K10: 20-24), moderate (K10: 25-29) and severe PD (K10: 30-50). Both crude and adjusted HSUs were calculated from participants' SF-36 profiles, considering potential confounders such as smoking, marital status, remoteness, education and income levels. The calculations were based on the SF-6D algorithm and aligned with Australian population norms. Additionally, the HSUs were stratified by age, sex and PD categories. Disutilities of PD, representing the mean difference between HSUs of people with PD and those without, were also calculated for each group. RESULTS: The average age of individuals was 46.130 years (46% male), and 31% experienced PD in the last 4 weeks. Overall, individuals with PD had significantly lower mean HSUs than those likely to be no PD, 0.637 (95% confidence interval [CI] 0.636, 0.640) vs 0.776 (95% CI 0.775, 0.777) i.e. disutility: -0.139 [95% CI -0.139, -0.138]). Mean disutilities of -0.108 (95% CI -0.110, -0.104), -0.140 (95% CI -0.142, -0.138), and -0.188 (95% CI -0.190, -0.187) were observed for mild PD, moderate PD and severe PD, respectively. Disutilities of PD also differed by age and sex groups. For instance, female individuals had up to 0.049 points lower mean HSUs than male individuals across the three classifications of PD. There was a clear decline in health-related quality of life with increasing age, demonstrated by lower mean HSUs in older population age groups, that ranged from 0.818 (95% CI 0.817, 0.818) for the 15-24 years age group with no PD to 0.496 (95% CI 0.491, 0.500) for the 65+ years age group with severe PD). Across all ages and genders, respondents were more likely to report issues in certain dimensions, notably vitality, and these responses did not uniformly align with ageing. CONCLUSIONS: The burden of PD in Australia is substantial, with a significant impact on female individuals and older individuals. Implementing age-specific and sex-specific healthcare interventions to address PD among Australian adults may greatly alleviate this burden. The PD state-specific HSUs calculated in our study can serve as valuable inputs for future health economic evaluations of PD in Australia and similar populations.

Trends in socioeconomic inequalities in breast cancer mortality in Canada: 1992-2019.

PURPOSE: Breast cancer is the second leading cause of death from cancer among Canadian females. This study aimed to quantify and assess trends in education and income inequalities in the mortality rate of breast cancer in Canada from 1992 to 2019. METHODS: We constructed a census division-level dataset pooled from the Canadian Vital Death Statistics Database (CVSD), the Canadian Census of the Population (CCP), and the National Household Survey (NHS) to examine trends in education and income inequalities in the mortality rate of breast cancer in Canada over the study period. The age-standardized Concentration index (C) was used to quantify income and education inequalities in breast cancer mortality over time. RESULTS: The national crude mortality rate of breast cancer has decreased in Canada from 1992 to 2019, with Alberta, British Columbia, Manitoba, Ontario, Prince Edward Island, and Quebec having the greatest decreases in mortality rate. The age-standardized C for education and income inequalities were always negative for all the study years, meaning that the mortality rate of breast cancer was higher among less-educated and poorer females. Moreover, the results indicate a growing trend in the concentration of breast cancer mortality among females with lower income and education from 1992 to 2019. CONCLUSION: The increasing concentration of breast cancer mortality among low socioeconomic status females remains a challenge in Canada. Continuous efforts are needed within Canadian healthcare system to improve the prevention and treatment of breast cancer for this population.

The contributions of avoidable causes of death to gender gap in life expectancy and life disparity in the US and Canada: 2001-2019.

OBJECTIVES: This study measures public health policies' and healthcare system's influence, by assessing the contributions of avoidable deaths, on the gender gaps in life expectancy and disparity (GGLD and GGLD, respectively) in the United States (US) and Canada from 2001 to 2019. METHODS: To estimate the GGLE and GGLD, we retrieved age- and sex-specific causes of death from the World Health Organization's mortality database. By employing the continuous-change model, we decomposed the GGLE and GGLD by age and cause of death for each year and over time using females as the reference group. RESULTS: In Canada and the US, the GGLE (GGLD) narrowed (increased) by 0.9 (0.2) and 0.2 (0.3) years, respectively. Largest contributor to the GGLE was non-avoidable deaths in Canada and preventable deaths in the US. Preventable deaths had the largest contributions to the GGLD in both countries. Ischemic heart disease contributed to the narrowing GGLE/GGLD in both countries. Conversely, treatable causes of death increased the GGLE/GGLD in both countries. In Canada, "treatable & preventable" as well as preventable causes of death narrowed the GGLE while opposite was seen in the US. While lung cancer contributed to the narrowing GGLE/GGLD, drug-related death contributed to the widening GGLE/GGLD in both countries. Injury-related deaths contributed to the narrowing GGLE/GGLD in Canada but not in the US. The contributions of avoidable causes of death to the GGLE declined in the age groups 55-74 in Canada and 70-74 in the US, whereas the GGLE widened for ages 25-34 in the US. CONCLUSION: Canada experienced larger reduction in the GGLE compared to the US attributed mainly to preventable causes of death. To narrow the GGLE and GGLD, the US needs to address injury deaths. Urgent interventions are required for drug-related death in both countries, particularly among males aged 15-44 years.

Umbilical cord blood thyroid hormones are inversely related to telomere length and mitochondrial DNA copy number.

Hypothyroidism has been linked to reduced mortality rate and increased lifespan and health span. Telomere shortening, enhanced oxidative stress, and reduced cellular mitochondrial content are important hallmarks of aging shown to be related to age-associated diseases. It was proposed that the status of these markers in early life can be predictive of lifespan and the predisposition to certain age-associated disease in adulthood. Animal studies indicated that prenatal injection of thyroid hormones affects postnatal telomere length. Here, we sought to determine whether thyroid hormones TSH and fT4 are related to the telomere length, mitochondrial DNA copy number (mtDNAcn), and oxidative stress resistance marker GPX in the cord blood of newborns. In this study, we analyzed 70 mothers (18-42 years) and neonate dyads born in 2022 at the Nik Nafs maternity Hospital in Rafsanjan. The relative telomere length (RTL) and mtDNAcn were measured in the genomic DNA of cord blood leukocytes using real-time PCR. GPX enzyme activity was measured in the serum using colorimetric assays. In this study the correlation between these markers and the cord blood TSH and fT4 hormones were assessed using regression models. We found a reverse relationship between TSH levels and RTL in the cord blood of neonates. Additionally, our results displayed increased TSH levels associated with enhanced GPX activity. Regarding the mitochondrial DNA copy number, we found an indirect relationship between fT4 level and mtDNAcn only in male newborns. Future analyses of various oxidative stress markers, mitochondrial biogenesis status, telomerase activity, and the level of DNA damage are warranted to demonstrate the underlying mechanism of our observations.

Breastfeeding and infant care as 'sexed' care work: reconsideration of the three Rs to enable women's rights, economic empowerment, nutrition and health.

Women's lifelong health and nutrition status is intricately related to their reproductive history, including the number and spacing of their pregnancies and births, and for how long and how intensively they breastfeed their children. In turn, women's reproductive biology is closely linked to their social roles and situation, including regarding economic disadvantage and disproportionate unpaid work. Recognizing, as well as reducing and redistributing women's care and domestic work (known as the 'Three Rs'), is an established framework for addressing women's inequitable unpaid care work. However, the care work of breastfeeding presents a dilemma, and is even a divisive issue, for advocates of women's empowerment, because reducing breastfeeding and replacing it with commercial milk formula risks harming women's and children's health. It is therefore necessary for the interaction between women's reproductive biology and infant care role to be recognized in order to support women's human rights and enable governments to implement economic, employment and other policies to empower women. In this paper, we argue that breastfeeding-like childbirth-is reproductive work that should not be reduced and cannot sensibly be directly redistributed to fathers or others. Rather, we contend that the Three Rs agenda should be reconceptualized to isolate breastfeeding as 'sexed' care work that should be supported rather than reduced with action taken to avoid undermining breastfeeding. This means that initiatives toward gender equality should be assessed against their impact on women's ability to breastfeed. With this reconceptualization, adjustments are also needed to key global economic institutions and national statistical systems to appropriately recognize the value of this work. Additional structural supports such as maternity protection and childcare are needed to ensure that childbearing and breastfeeding do not disadvantage women amidst efforts to reduce gender pay gaps and gender economic inequality. Distinct policy interventions are also required to facilitate fathers' engagement in enabling and supporting breastfeeding through sharing the other unpaid care work associated with parents' time-consuming care responsibilities, for both infants and young children and related household work.

Evaluation of epigenetic-related gene expression (DNMT, HDAC1) in Iranian patients with systemic lupus erythematosus.

BACKGROUND: Systemic lupus erythematosus (SLE) is an autoimmune disease in which the immune system abnormally reacts against cells and tissues leading to inflammation. Epigenetic alterations, including DNA methylation and histone modification, have critical effects on autoimmune disease and SLE pathogenesis via dysregulation of critical genes. AIMS: The purpose of this study was to evaluate the epigenetic-related gene expression of DNA methyltransferase (DNMT) and histone deacetylase 1 (HDAC1) in Iranian patients with SLE. METHODS: This matched case-control study included 16 people with SLE and 16 healthy people who were referred to the Rafsanjani rheumatology clinic, in southeast Iran. The expression of DNMT and HDAC1 genes was measured through a real-time PCR assay of blood samples. RESULTS: DNMT gene expression did not differ significantly between SLE and healthy groups (P=0.21). In contrast, HDAC1 gene expression was enhanced in the SLE group, but this enhancement failed to reach statistical significance (P=0.94). CONCLUSION: The results of this study suggest that overexpression of HDAC1 could serve as a diagnostic for SLE disease. Additional studies with larger sample sizes are required to confirm our findings. Evaluation of other genes related to SLE disease is essential and may help to make an accurate diagnosis of the disease.

Interrupting bedtime to reverse frailty levels in acute care: a study protocol for the Breaking Bad Rest randomized controlled trial.

BACKGROUND: Hospitalized older patients spend most of the waking hours in bed, even if they can walk independently. Excessive bedrest contributes to the development of frailty and worse hospital outcomes. We describe the study protocol for the Breaking Bad Rest Study, a randomized clinical trial aimed to promoting more movement in acute care using a novel device-based approach that could mitigate the impact of too much bedrest on frailty. METHODS: Fifty patients in a geriatric unit will be randomized into an intervention or usual care control group. Both groups will be equipped with an activPAL (a measure of posture) and StepWatch (a measure of step counts) to wear throughout their entire hospital stay to capture their physical activity levels and posture. Frailty will be assessed via a multi-item questionnaire assessing health deficits at admission, weekly for the first month, then monthly thereafter, and at 1-month post-discharge. Secondary measures including geriatric assessments, cognitive function, falls, and hospital re-admissions will be assessed. Mixed models for repeated measures will determine whether daily activity differed between groups, changed over the course of their hospital stay, and impacted frailty levels. DISCUSSION: This randomized clinical trial will add to the evidence base on addressing frailty in older adults in acute care settings through a devices-based movement intervention. The findings of this trial may inform guidelines for limiting time spent sedentary or in bed during a patient's stay in geriatric units, with the intention of scaling up this study model to other acute care sites if successful. TRIAL REGISTRATION: The protocol has been registered at clinicaltrials.gov (identifier: NCT03682523).

Income-Related Inequities in Primary and Specialist Care Among First Nations Peoples Living Off-Reserve in Canada.

BACKGROUND: Improving equity in healthcare is a primary goal of health policy in Canada. Although the investigation of equity in healthcare utilization is common in the general population, little research has been conducted to assess equity in healthcare utilization within First Nations peoples living in Canada. OBJECTIVE: To examine income-related inequities in primary care (family doctor/general practitioner and nurse practitioner care) and specialist care within status and non-status First Nations adults living off-reserve. METHODS: Using the 2017 Aboriginal Peoples Survey (APS), a nationally representative survey of Indigenous peoples living off-reserve in Canada, we analyzed income-related inequities in healthcare among Indigenous adults (>18 years) who self-identified as a member of any First Nations group in Canada. Logistic regression analysis was performed to identify factors associated with the utilization of primary and specialist care. The Horizontal Inequity index (HI), which measures unequal healthcare use by income for equal need, was used to quantify and decompose income-related inequities for primary and specialist care for status and non-status, and total First Nations groups. RESULTS: The regression results revealed higher primary and specialist care use among females, high socioeconomic status (high income and more educated) and status First Nations peoples in Canada. The positive values of the HI suggested a higher concentration of primary care and specialist care utilization among higher income First Nations peoples after adjusting for healthcare need. These pro-rich inequities persisted for the total First Nations populations, and for those in each status group individually. The decomposition results suggested observed inequities in both primary and specialist care among First Nations peoples can be predominantly attributed to the unequal distribution of education and income. CONCLUSION: Although primary and specialist services in Canada are free at the point of the provision, we found pro-rich inequities in healthcare use among First Nations adults living off-reserve in Canada. These results warrant policies and initiatives to address barriers to healthcare use within and outside health system among low-income First Nations peoples living off-reserve.

Trends in Socioeconomic Inequalities in Breast Cancer Incidence Among Women in Canada.

INTRODUCTION: Breast cancer is the most common cancer among females in Canada. This study examines trends in socioeconomic inequalities in the incidence of breast cancer in Canada over time from 1992 to 2010. METHODS: A census division level dataset was constructed using the Canadian Cancer Registry, Canadian Census of the Population and National Household Survey. A summary measure of the Concentration index (C), which captures inequality across socioeconomic groups, was used to measure income and education inequalities in breast cancer incidence over the 19-year period. RESULTS: The crude breast cancer incidence increased in Canada between 1992 and 2010. Age-standardized C values indicated no income or education inequalities in breast cancer incidence in the years from 1992 to 2004. However, the incidence was significantly concentrated among females in high income and highly educated neighbourhoods almost half the time in the 6 most recent years (2005-2010). The trend analysis indicated an increase in breast cancer incidence among females living in high income and highly educated neighbourhoods. CONCLUSION: Breast cancer incidence in Canada was associated with increased socioeconomic status in some more recent years. Our study findings provide previously unavailable empirical evidence to inform discussions on socioeconomic inequalities in breast incidence.

The COVID-19 pandemic and healthcare utilization in Iran: evidence from an interrupted time series analysis.

BACKGROUND: This study aimed to examine the effect of the coronavirus disease 2019 (COVID-19) outbreak on the hospitalization rate, emergency department (ED) visits, and outpatient clinic visits in western Iran. METHODS: We collected data on the monthly hospitalization rate, rate of patients referred to the ED, and rate of patients referred to outpatient clinics for a period of 40 months (23 months before and 17 months after the COVID-19 outbreak in Iran) from all 7 public hospitals in the city of Kermanshah. An interrupted time series analysis was conducted to examine the impact of COVID-19 on the outcome variables in this study. RESULTS: A statistically significant decrease of 38.11 hospitalizations per 10,000 population (95% confidence interval [CI], 24.93-51.29) was observed in the first month of the COVID-19 outbreak. The corresponding reductions in ED visits and outpatient visits per 10,000 population were 191.65 (95% CI, 166.63-216.66) and 168.57 (95% CI, 126.41-210.73), respectively. After the initial reduction, significant monthly increases in the hospitalization rate (an increase of 1.81 per 10,000 population), ED visits (an increase of 2.16 per 10,000 population), and outpatient clinic visits (an increase of 5.77 per 10,000 population) were observed during the COVID-19 pandemic. CONCLUSION: Our study showed that the utilization of outpatient and inpatient services in hospitals and clinics significantly declined after the COVID-19 outbreak, and use of these services did not return to pre-outbreak levels as of June 2021.

Disparities in access to primary care are growing wider in Canada.

Canadian provinces and territories have undertaken varied reforms to how primary care is funded, organized, and delivered, but equity impacts of reforms are unclear. We explore disparities in access to primary care by income, educational attainment, dwelling ownership, immigration, racialization, place of residence (metropolitan/non-metropolitan), and sex/gender, and how these have changed over time, using data from the Canadian Community Health Survey (2007/08 and 2015/16 or 2017/18). We observe disparities by income, educational attainment, dwelling ownership, recent immigration, immigration (regular place of care), racialization (regular place of care), and sex/gender. Disparities are persistent over time or increasing in the case of income and racialization (regular medical provider and consulted with a medical professional). Primary care policy decisions that do not explicitly consider existing inequities may continue to entrench them. Careful study of equity impacts of ongoing policy reforms is needed.

Evolution and biogeography of apple stem grooving virus.

BACKGROUND: Apple stem grooving virus (ASGV) has a wide host range, notably including apples, pears, prunes and citrus. It is found worldwide. METHOD: In this study, two near complete genomes, and seven coat protein (CP) sequences of Iranian isolates from apple were determined. Sequences added from GenBank provided alignments of 120 genomic sequences (54 of which were recombinant), and 276 coat protein genes (none of them recombinant). RESULT: The non-recombinant genomes gave a well supported phylogeny with isolates from diverse hosts in China forming the base of the phylogeny, and a monophyletic clade of at least seven clusters of isolates from around the world with no host or provenace groupings among them, and all but one including isolates from China. The six regions of the ASGV genome (five in one frame, one - 2 overlapping) gave significantly correlated phylogenies, but individually had less statistical support. The largest cluster of isolates contained those from Iran and had isolates with worldwide provenances, and came from a wide range of mono- and dicotyledonous hosts. Population genetic comparisons of the six regions of the ASGV genome showed that four were under strong negative selection, but two of unknown function were under positive selection. CONCLUSION: ASGV most likely originated and spread in East Asia in one or more of various plant species, but not in Eurasia; the ASGV population of China had the greatest overall nucleotide diversity and largest number of segregating sites.

Ten years after the 2015 Canada Health Transfer reform: A persistent equity concern of insufficient risk-equalization.

Two guiding principles related to equity in healthcare, both in Canada and internationally, are that healthcare should be financed according to the ability-to-pay and utilized based on need. The Canada Health Act (CHA, 1984) aims to remove financial barriers and provide equitable access to healthcare in Canada. Contingent on meeting the conditions set out in the CHA, each province receives federal funding through the Canada Health Transfer (CHT). In 2014-2015, the CHT underwent a major change in that all provinces are now receiving funds on a per capita basis. We highlight equity concerns regarding the CHT allocations by reviewing the three main provincial level healthcare need indicators of its population: aging populations, the prevalence of chronic conditions, and population density. Results show that there are significant variations in all the three indicators among Canadian provinces. Specifically, Atlantic provinces have high values for all indicators, thus making per capita healthcare costs larger in these provinces. In contrast, larger provinces, particularly Alberta, are low in all indicators compared to the rest of Canada. Having a per capita CHT allocation means that provinces with a high range of healthcare need indicator values are in a more difficult situation to deliver sufficient healthcare to its population. A need-based allocation system can better meet the important policy objective of equity in healthcare for Canada.

The contributions of injury deaths to the gender gap in life expectancy and life disparity in Eastern Mediterranean Region.

BACKGROUND: Injury deaths constitute a major avoidable cause of death affecting life expectancy to a different degree in men and women. This study quantified the contributions of injury deaths to the gender gap in life expectancy (GGLE) and life disparity (GGLD) in nine Eastern Mediterranean Region (EMR) countries. METHODS: We retrieved annual data on age-sex specific causes of death from the World Health Organization mortality database for EMR countries with at least 2-year consecutive data during 2010-2019. The injury-related deaths were categorized into five groups: transport accidents, other accidental injuries, intentional self-harm, assault and events of undetermined intent. Considering women as the reference, the GGLE and GGLD were decomposed by age and causes of death, using a continuous-change model. RESULTS: The largest and smallest GGLE were observed in Kuwait (5.2 years) and Qatar (- 1.2 years), respectively. Qatar (- 2.2 years) and Oman (0.2 years) had the highest and lowest GGLD. The highest contributions of injury deaths to the GGLE/GGLD were seen in Libya (1.8/- 1.2 years), followed by Iran (1.2/- 0.8 years). Among injury causes, transport accidents were the leading cause of GGLE in all countries but Libya and Morocco, with Iran having the greatest contributions (0.6 years). Injury deaths in men aged 15-29 years accounted for 33% [41%] (Kuwait) to 55% [65%] (Oman) of total GGLE [GGLD] attributable to injury deaths. CONCLUSIONS: High injury deaths, particularly transport accidents, among young men contributed substantially to the GGLE and GGLD across nine EMR countries in this study. This highlights the need for implementing preventing policies to reduce the burden of injury deaths specifically in young men.

Decomposition of socioeconomic inequalities in catastrophic out-of-pocket expenditure for healthcare in Canada.

Despite a publicly financed health system for physician and hospital services, out-of-pocket health expenditure (OHE) accounts for a significant proportion of healthcare financing in Canada. We pooled annual Surveys of Household Spending conducted from 2010 to 2017 (n=34,105) to estimate the catastrophic out-of-pocket expenditure (COHE) burden using two definitions: the budget share (OHE exceeding 10% of a household's total consumption) and capacity-to-pay (OHE exceeding 40% of a household's total consumption minus basic subsistence needs). The Wagstaff index (WI) and the Erreygers Index (EI) were used to quantify and decompose socioeconomic inequalities in COHE. Results demonstrate that approximately 6% and 10% of the households faced COHE in Canada, depending on whether we used the budget share or capacity-to-pay approach to measure COHE. The COHE was found to be concentrated among low socioeconomic status (SES) households. Decomposition results indicate that besides SES, household characteristics (e.g., households headed by females and the presence of senior(s) in the households) were the most important factors contributing to the concentration of COHE among the poorer households. The lower utilization of healthcare services among the poor resulted in reduced COHE among these households. A higher burden of COHE is a major concern in Canada. Policies to enhance risk protection among specific populations such as the seniors are required to improve equity in healthcare financing in Canada.

Effects of maternal employment on child malnutrition in South Asia: An instrumental variable approach.

OBJECTIVE: Although the association between child malnutrition and maternal employment status has been widely studied in several developing countries, the causal effect of mothers' employment on their children's health remains largely unknown. The aim of this study was to examine the causal effect of maternal employment on child malnutrition in five South Asian countries. METHOD: This study used a data set of >55 200 children ages 0 to 5 y by pooling the most recent Demographic Health Surveys (DHS) from Bangladesh, India, the Maldives, Nepal, and Pakistan. An instrumental variable (IV) method was applied to measure the causal effect of the mother's employment status (working mother) on stunting and underweight among children. RESULTS: Results showed that of the children in South Asia, 37.9% and 33.6% were stunted and underweight, respectively. The IV estimates suggested that maternal employment significantly increased stunting and underweight in children. For example, the likelihood of stunting and underweight increased by about 9.5% and 6.3% points, respectively, in South Asia when mothers worked. The likelihoods in Bangladesh (39.9 and 26.6%) and Pakistan (28 and 33.4%) were high but were at moderate levels in India (5.3 and 4.2%) and Nepal (8 and 9%). CONCLUSIONS: In the present study, an adverse effect of maternal labor market participation on the nutritional status of under-five children in South Asian countries was found. These findings could be helpful for policymakers in South Asian countries to adopt suitable policies to reduce malnutrition among children, especially for the children of employed mothers.

Evaluation of H19, Mest, Meg3, and Peg3 genes affecting growth and metabolism in umbilical cord blood cells of infants born to mothers with gestational diabetes and healthy mothers in Rafsanjan City, Iran.

Hyperglycemia during the first trimester leads to an increased risk of innate malformations as well as death at times close to delivery dates. The methylated genes include those from paternal H19 and PEG3 and those from maternal MEST and MEG3 that are necessary for the growth and regulation of the human fetus and its placenta. The aim of this study was to evaluate and compare the expression of these genes in the cord blood of healthy infants born to mothers with gestational diabetes mellitus (GDM) and healthy mothers.This case-control study was conducted on the cord blood of 40 infants born to mothers with GDM and 35 infants born to healthy mothers. Mothers were identified by measuring oral glucose tolerance in the 24th-26th week of pregnancy. Cord blood was obtained post-delivery, and cord blood mononuclear cells were immediately extracted, using Ficoll solution. Then, RNA extraction and cDNA synthesis were performed, and gene expression of MEG3, PEG3, H19, and MEST was assessed through quantitative real-time PCR.Findings show that the expression levels of MEG3, PEG3, H19, and MEST genes were significantly decreased in mononuclear cord blood cells of infants born to mothers with GDM when compared to those of the healthy control group.These findings reveal that the reduction of imprinted genes in mothers with GDM is most likely due to changes in their methylation by an epigenetic process. Considering the importance of GDM due to its high prevalence and its side effects both for mother and fetus, recognizing their exact mechanisms is of high importance. This has to be studied more widely.

Mind the Gap: What Factors Determine the Worse Health Status of Indigenous Women Relative to Men Living Off-Reserve in Canada?

BACKGROUND: Indigenous populations have the poorest health outcomes in Canada. In addition, some studies report notable gender health gaps among Indigenous populations of Canada, with greater disadvantages for Indigenous women. To date, the driving factors behind the health gaps between Indigenous women and men are poorly understood. METHOD: Using the four available Aboriginal People Surveys (APS) (2001, 2006, 2012, and 2017), we measure gender gaps in good general health (GGH) (i.e. good/very good/excellent self-rated health) among Indigenous adults (age 18 and above) living off-reserve in Canada. We apply the Oaxaca-Blinder (OB) decomposition method to identify the relative contribution of health endowments and the return to these endowments to the gender health gaps among Indigenous peoples. RESULTS: Indigenous men are found to have a higher rate of GGH than their female counterparts. The gender health gap among Indigenous people has somewhat widened over the period 2001 to 2017. The widening of the gender health gap was observed in all four Indigenous identity groups, viz. registered First Nations, non-registered First Nations, Métis, and Inuit. The OB decomposition suggests that differences in endowments such as employment status and income between men and women explain between 30 to 60% of the gender health gap among Indigenous populations in Canada over the study period. CONCLUSION: The social determinants of health appear to be the main factor explaining the gender health gap within the Indigenous peoples living in Canada. Policies improving employment opportunities and income among Indigenous women may potentially reduce the gender health gap within Indigenous population in Canada.

Sex Differences in Trends in Incidence of Thoracic Aortic Aneurysm Repair and Aortic Dissection: 2005-2015.

Background: The purpose of this study was to examine trends in the incidence of thoracic aortic aneurysm (TAA) repair and aortic dissection. Methods: A retrospective study was conducted of patients from the period 2005-2015 with thoracic aortic disease. Unadjusted mortality was compared in women vs men. Rates of scheduled TAA repair, dissection events, acute type A aortic dissection (TAAD) repair, and aorta-related mortality were obtained from our institution's clinical registry and administrative data sources and used to calculate the age-adjusted incidence for each sex, adjusted to the Canadian standard population. Weighted linear regression was performed to analyze trends over time. Results: A total of 382 scheduled TAA repair operations, 345 dissection events, 85 TAAD repairs, and 182 aorta-related mortalities were identified. Women accounted for 23% of TAA repairs, 39% of dissection events, 22% of TAAD repairs, and 45% of aorta-related mortalities. The incidence of TAA repair was 3.5 per 100,000 person-years (95% confidence interval [CI]: 3.2-3.9), and increased in men (P = 0.02) but not women (P = 0.10) over time. The incidence of aortic dissection was 3.4 per 100,000 (95% CI: 3.1-3.8) and was stable over time (P = 0.43). The average annual age-adjusted incidence of TAAD repair was 0.8 per 100,000 (95% CI: 0.6-1.0) and increased over time (P = 0.001). The overall incidence of aorta-related mortality was 1.8 per 100,000 (95% CI: 1.5-2.0) and decreased over time (P = 0.02). Conclusion: The incidence of TAA repair is increasing in men but not women. Although aorta-related mortality is decreasing overall, disparities exist between the male and female population.

Introduction: L'objectif de cette étude était d'examiner les tendances relatives à l'incidence des réparations d'anévrisme de l'aorte thoracique (AAT) et de dissection aortique. Méthodes: Nous avons mené une étude rétrospective de patients atteints d'une maladie de l'aorte thoracique de la période 2005-2015. Nous avons comparé la mortalité non ajustée entre les femmes et les hommes. Nous avons obtenu les taux de réparations planifiées d'AAT, de dissections, de dissections aortiques de type A (DATA) à la phase aiguë et de mortalité d'origine aortique du registre clinique de notre établissement et des sources de données administratives, et les avons utilisés pour calculer l'incidence ajustée selon l'âge pour chacun des sexes, ajustée à la population canadienne type. Nous avons effectué une régression linéaire pondérée pour analyser les tendances temporelles. Résultats: Nous avons recensé un total de 382 réparations planifiées d'AAT, 345 dissections, 85 réparations de DATA et 182 cas de mortalité d'origine aortique. Les femmes représentaient 23 % des cas de réparation d'AAT, 39 % des cas de dissection, 22 % des cas de réparations de DATA et 45 % des cas de mortalité d'origine aortique. L'incidence des réparations d'AAT était de 3,5 par 100 000 années-personnes (intervalle de confiance [IC] à 95 % : 3,2-3,9) et augmentait chez les hommes (P = 0,02), mais non chez les femmes (P = 0,10) avec le temps. L'incidence des dissections aortiques était de 3,4 par 100 000 (IC à 95 % : 3,1-3,8) et était stable au fil du temps (P = 0,43). L'incidence moyenne annuelle selon l'âge de réparations de DATA était de 0,8 par 100 000 (IC à 95 % : 0,6-1,0) et augmentait avec le temps (P = 0,001). L'incidence globale de mortalité d'origine aortique était de 1,8 par 100 000 (IC à 95 % : 1,5-2,0) et diminuait avec le temps (P = 0,02). Conclusion: L'incidence des réparations d'AAT augmente chez les hommes, mais non chez les femmes. Bien que la mortalité d'origine aortique tende dans l'ensemble à diminuer, il existe des disparités entre la population masculine et la population féminine.
