Ethnic inequalities in ischemic stroke occurrence are partly mediated by air pollution
Ethnic disparities in ischemic stroke are substantial and differences in exposure to air pollution have been demonstrated as well. However, the role of air pollution in mediating ethnic disparities in risk of ischemic stroke remains unclear. Understanding this relationship is crucial, as air pollution is a major modifiable risk factor for ischemic stroke. This study aims to determine whether air pollution exposure mediates ischemic stroke risk di…
Socio-demographic and socio-economic differences in the availability of green space in the Netherlands
We aimed to map the spatial distribution of green space in the Netherlands, and to first comprehensively assess socio-demographic and socio-economic differences in the availability of green space in the Netherlands. Data was analyzed from all registered residents of the Netherlands aged one and above on January 1, 2017 (16,440,620 individuals). Socio-demographic and socio-economic information was derived from Statistics Netherlands. Data on green…
Air pollution exposure and incidence of cardiometabolic diseases
While the antioxidative potential of certain vitamins and minerals in cardio-protection has garnered increasing interest, their ability to attenuate associations between air pollution exposure and cardiometabolic diseases (CMDs) remains unexplored. This study examined the associations of air pollution (particulate matter including ultrafine particles (UFP), and nitrogen oxides, including NO2 and NOx) and six dietary antioxidants with incident non…
Socioeconomic inequalities and ambient air pollution exposure in school-aged children living in an affluent society
Low neighborhood income was significantly associated with higher levels of air pollution, while parental education level was not significantly associated. Children from parents with a low education and low income were exposed to the highest levels of air pollution
Family is all that matters
We prospectively examined the association between structure, function, and quality of social relations and self-rated health (SRH) in U.S. adults followed over 10 years in the population-based National Social Life, Health, and Aging Project (NSHAP). Large social network and high positive/negative social support were measured at baseline and defined as the highest quartile. These three binary measures were reported from friends, family, and partne…
Temporal Trends in Air Pollution Exposure across Socioeconomic Groups in The Netherlands
Air pollution exposure has been linked to detrimental health outcomes. While cross-sectional studies have demonstrated socioeconomic disparities in air pollution exposure, longitudinal evidence on these disparities remains limited. The current study investigates trends in residential air pollution exposure across socioeconomic groups in the Netherlands from 2014 to 2019. Our dataset includes over 12.5 million individuals, aged 18 years and above,…
Green space visits among Turkish and South Asian Surinamese women with a high cardiometabolic risk living in disadvantaged neighborhoods in the Netherlands
Motives, means and prerequisites to visit green space of women with a Turkish or South Asian Surinamese background who live in disadvantaged neighborhoods span multiple interacting themes. Future studies examining the relationship between green space and health should consider interactions between motives, means, prerequisites and ethnicity. The possibility of expanding the multifunctionality of green spaces to provide marginalized populations wi…
Differential effects of air pollution on ischemic stroke and ischemic heart disease by ethnicity in a nationwide cohort in the Netherlands
Associations between air pollutants and ischemic stroke or IHD differ notably between ethnic groups in the Netherlands. Policies to reduce air pollution and prevent ischemic stroke should target populations vulnerable to air pollution with a high cardiovascular disease risk
Neighbourhood walkability in relation to cognitive functioning in patients with disorders along the heart-brain axis
This study examined associations of neighbourhood walkability with cognitive functioning (i.e., global cognition, memory, language, attention-psychomotor speed, and executive functioning) in participants without or with either heart failure, carotid occlusive disease, or vascular cognitive impairment. Neighbourhood walkability at baseline was positively associated with global cognition and attention-psychomotor speed. These associations were stro…
Does the neighbourhood food environment contribute to ethnic differences in diet quality? Results from the Helius study in Amsterdam, the Netherlands
Objective: The aim of the current study was to establish whether the neighbourhood food environment, characterised by the healthiness of food outlets, the diversity of food outlets and fast-food outlet density within a 500 m or 1000 m street network buffer around the home address, contributed to ethnic differences in diet quality. Design: Cross-sectional cohort study. Setting: Amsterdam, the Netherlands. Participants: Data on adult participants o…
Mortality after hospital admission for heart failure
Mortality after hospitalization for new onset HF remains high, however, both short-term and long-term survival is improving over time. This improvement was similar across all ages and equally strong in women as in men
Activity-based air pollution exposure assessment
Long-term air pollution exposure may lead to an increase in incidences and mortality rates of chronic diseases and adversely affect human health. The effects of long-term air pollution exposure have not been comprehensively studied due to the lack of human mobility data collected over a long period. In this study, we develop and apply a personal mobility model to long-term hourly air pollution concentration predictions to quantify personal long-t…
Does education level affect the efficacy of a community based salt reduction program? - A post-hoc analysis of the China Rural Health Initiative Sodium Reduction Study (CRHI-SRS)
The trial was registered with clinicaltrial.gov ( NCT01259700 )
Trends in risk factors for coronary heart disease in the Netherlands
Four out of six risk factors for CHD showed a favourable or stable trend. The rise in diabetes mellitus and BMI is worrying with respect to CHD morbidity and mortality
Estimating the potential contribution of stroke treatments and preventative policies to reduce the stroke and ischemic heart disease mortality in Turkey up to 2032
Our modeling study suggests that effective and evidence-based food policies at the population level could massively contribute to reduction in ischemic stroke and IHD mortality in a decade and deliver bigger gains compared to healthcare based interventions for primary and secondary prevention
PP05 Shifts in the type of Coronary Heart Disease Hospitalisations
Background Shifts in the burden of coronary heart disease (CHD) from an acute to chronic illness may have important public health consequences. The objective of this study was to assess age-gender-specific time trends in rates and characteristics of acute and chronic forms of CHD hospital admissions in the Netherlands. Methods Using nationwide Dutch registers, we assessed time trends between 1998 and 2007 in hospitalisation rates of 188,266 acute…
Neighbourhood socioeconomic inequalities in incidence of acute myocardial infarction
Neighbourhood socioeconomic inequalities were observed in AMI incidence in the Netherlands, but the magnitude across age-gender groups depended on whether inequality was expressed in relative or absolute terms. Relative socioeconomic inequalities were high in young persons and women, where the absolute burden of AMI was low. Absolute socioeconomic inequalities in AMI were highest in the age-gender groups of middle-aged men and elderly women, wher…
O3-2.3 Linkage of data in the study of ethnic inequalities and inequities in health outcomes in the Netherlands
Background Ethnic variation in health outcomes and in utilisation of health services has been observed worldwide. Quantifying and understanding this variation is essential to identify the health needs of ethnically diverse population. As many ethnic minority populations in the Netherlands, and elsewhere, are ageing the burden of cardiovascular diseases (CVD) is increasingly becoming important. Therefore, one major health task is the routine colle…
Age- and gender-specific risk of death after first hospitalization for heart failure
This study clearly shows age- and gender differences in short- and long-term risk of death after first hospitalization for HF with men having higher short- and long-term risk of death than women. As our study population includes both men and women from all ages, the estimates we provide maybe a good reflection of 'daily practice' risk of death and therefore be valuable for clinicians and policymakers
P04 Age- and gender-specific risk of death after first hospital admission for heart failure
Objective Heart failure (HF) is an important public health problem. Detailed information on prognosis following hospital admission is crucial for cost-effectiveness analysis and determination of the burden of HF on the health care system. However, such data are scarce. Therefore, the objective of this study was to provide mortality risk following hospital admission stratified by age- and gender. Design Hospital based follow-up study. Setting and …
Coronary heart disease mortality in The Netherlands from 1972 to 2007
Background Coronary heart disease (CHD) mortality has steadily declined since the early 1970s in The Netherlands. Recent work suggests that in some Western countries the rate of decline in some groups has begun to decrease and may be starting to plateau or even reverse. These changes may be a result of changes in the pattern for major cardiovascular risk factor trends. Methods Data for all deaths between 1972 and 2007 in The Netherlands were grou…
P53 Mortality after hospital admission clearly varies between atherosclerotic diseases located at different vascular beds
Objective Most studies providing data on survival in patients with atherosclerosis only address a single disease site: heart, brain or legs. Therefore, our objective was to determine risk of death after first hospital admission for atherosclerotic disease located at different sites. Design Hospital-based follow-up study. Setting and Participants A nationwide cohort of patients hospitalised for the first time for acute myocardial infarction (AMI),…
