Low-level exposure to arsenic in drinking water and incidence rate of stroke: A cohort study in Denmark.

Introduction: High arsenic concentration in drinking water is associated with a higher incidence rate of stroke, but only few studies have investigated an association with arsenic in drinking water at low concentration (<50 μg/L).

Objective: To examine if arsenic in drinking water at low concentration was associated with higher incidence rate of stroke in Denmark.

Methods: A total of 57,053 individuals from the Danish Diet, Cancer, and Health cohort was included in the study (enrolment in 1993-1997, age 50-64 years), of which 2195 individuals had incident stroke between enrolment and November 2009.

Low-level arsenic in drinking water and risk of incident myocardial infarction: A cohort study.

Background: Epidemiological studies have shown that intake of drinking water with high levels of arsenic (>100μg/L) is associated with risk for cardiovascular diseases, but studies on lower levels of arsenic show inconsistent results.

Objective: The aim of this study was to investigate the relationship between exposure to low level arsenic in drinking water and risk of myocardial infarction in Denmark.

Methods: From the Danish Diet, Cancer and Health cohort of 57,053 people aged 50-64 years at enrolment in 1993-1997, we identified 2707 cases of incident myocardial infarction from enrolment to end of follow-up in February 2012.

Long-term exposure to fine particulate matter and incidence of diabetes in the Danish Nurse Cohort.

Aims/hypothesis: It has been suggested that air pollution may increase the risk of type 2 diabetes but data on particulate matter with diameter <2.5μm (PM2.5) are inconsistent.

Social inequality and incidence of and survival from cancers of the oesophagus, stomach and pancreas in a population-based study in Denmark, 1994-2003.

We investigated the effect of socioeconomic, demographic and health-related indicators on the incidence of and survival from cancers of the oesophagus, stomach and pancreas diagnosed during 1994-2003 with follow-up through 2006 in Denmark using information from nationwide registers. The analyses were based on data on 2075 patients with cancer of the oesophagus, 2673 with stomach cancer and 3657 with pancreatic cancer in a cohort of 3.22 million persons born between 1925 and 1973 and aged >or=30 years.

Arsenic in drinking-water and risk for cancer in Denmark.

Background: Arsenic is a well-known carcinogen, which is often found in drinking-water. Epidemiologic studies have shown increased cancer risks among individuals exposed to high concentrations of arsenic in drinking-water, whereas studies of the carcinogenic effect of low doses have had inconsistent results.

Objective: Our aim was to determine if exposure to low levels of arsenic in drinking-water in Denmark is associated with an increased risk for cancer.
