- IMPORTANCE: The prevalence of cardiometabolic multimorbidity is increasing. OBJECTIVE: To estimate reductions in life expectancy associated with cardiometabolic multimorbidity. DESIGN, SETTING, AND PARTICIPANTS: Age- and sex-adjusted mortality rates and hazard ratios (HRs) were calculated using individual participant data from the Emerging Risk Factors Collaboration (689,300 participants; 91 cohorts; years of baseline surveys: 1960-2007; latest mortality follow-up: April 2013; 128,843 deaths). The HRs from the Emerging Risk Factors Collaboration were compared with those from the UK Biobank (499,808 participants; years of baseline surveys: 2006-2010; latest mortality follow-up: November 2013; 7995 deaths). Cumulative survival was estimated by applying calculated age-specific HRs for mortality to contemporary US age-specific death rates. EXPOSURES: A history of 2 or more of the following: diabetes mellitus, stroke, myocardial infarction (MI). MAIN OUTCOMES AND MEASURES: All-cause mortality and estimated reductions in life expectancy. RESULTS: In participants in the Emerging Risk Factors Collaboration without a history of diabetes, stroke, or MI at baseline (reference group), the all-cause mortality rate adjusted to the age of 60 years was 6.8 per 1000 person-years. Mortality rates per 1000 person-years were 15.6 in participants with a history of diabetes, 16.1 in those with stroke, 16.8 in those with MI, 32.0 in those with both diabetes and MI, 32.5 in those with both diabetes and stroke, 32.8 in those with both stroke and MI, and 59.5 in those with diabetes, stroke, and MI. Compared with the reference group, the HRs for all-cause mortality were 1.9 (95% CI, 1.8-2.0) in participants with a history of diabetes, 2.1 (95% CI, 2.0-2.2) in those with stroke, 2.0 (95% CI, 1.9-2.2) in those with MI, 3.7 (95% CI, 3.3-4.1) in those with both diabetes and MI, 3.8 (95% CI, 3.5-4.2) in those with both diabetes and stroke, 3.5 (95% CI, 3.1-4.0) in those with both stroke and MI, and 6.9 (95% CI, 5.7-8.3) in those with diabetes, stroke, and MI. The HRs from the Emerging Risk Factors Collaboration were similar to those from the more recently recruited UK Biobank. The HRs were little changed after further adjustment for markers of established intermediate pathways (eg, levels of lipids and blood pressure) and lifestyle factors (eg, smoking, diet). At the age of 60 years, a history of any 2 of these conditions was associated with 12 years of reduced life expectancy and a history of all 3 of these conditions was associated with 15 years of reduced life expectancy. CONCLUSIONS AND RELEVANCE: Mortality associated with a history of diabetes, stroke, or MI was similar for each condition. Because any combination of these conditions was associated with multiplicative mortality risk, life expectancy was substantially lower in people with multimorbidity.

- In the Piteå River Valley all persons with memory impairment that interferes with normal life are referred to one hospital department for clinical workup and diagnosis. 619 patients were assessed in the department during the years 1990–1995. Of these, 36.9% had Alzheimer’s disease (AD), 30.4% had vascular dementia (VaD), 3.0% had a mixed AD/VaD, 3.2% had frontotemporal dementia and 5.3% had other forms of dementia. Another 7% had memory impairment but no dementia. The overall mean annual incidence rate of clinically relevant dementia was 295/100,000 persons at risk and the mean prevalence rate was 755/100,000 persons. For persons 65 years and older the incidence and prevalence rates were 840 and 2,150/100,000 persons, respectively. This means that annually, approximately 300 persons/100,000 population over the age of 40 need medical attention or social services.

Although Coronary Mortality Has Decreased, Rates of Cardiovascular Disease Remain High: 21 Years of Follow-Up Comparing Cohorts of Men Born in 1913 With Men Born in 1943

Journal article (peer-reviewed)abstract
- BACKGROUND: Despite a decline in mortality rates from cardiovascular disease (CVD) in the past few decades, the burden of CVD in a contemporary population remains inadequately addressed. Therefore, this study was aimed to investigate secular trends in mortality from coronary artery disease and all-cause mortality over 2 decades, by comparing 2 cohorts of men born 30 years apart and evaluate the prediction of the risk of CVD and all-cause death in a contemporary random sample of Swedish men. METHODS AND RESULTS: Two cohorts of randomly selected men born in 1913 (855 men) and 1943 (798 men) were first examined at age 50 in 1963 and 1993, respectively, and followed longitudinally over 21 years. All-cause mortality and coronary artery disease death were lower in 50- to 71-year-old men born in 1943 compared with those born in 1913, with unadjusted hazard ratios of 0.57 (0.45-0.71) and 0.34 (0.22-0.53), respectively. After adjustment for risk factors (smoking, serum cholesterol, hypertension, systolic blood pressure, diabetes mellitus, body mass index, and physical activity), the differences between the cohorts remained significant for coronary artery disease, hazard ratios 0.57 (0.34-0.94), P=0.029, but not for all-cause mortality hazard ratios 0.82 (0.62-1.07), P=0.14. However, the rate of CVD events during follow-up was still high (30.7%) for the men born in 1943. No statistically significant interaction by birth cohort in contribution of risk factors to death was found between 2 cohorts except physical inactivity. CONCLUSIONS: Despite a marked reduction in the rate of coronary artery disease death over the past 30 years, the burden of CVD events and all-cause mortality remains high. Therefore, intensified efforts to modify contributing risk factors are still required.

- Background: The role of water hardness as a risk factor for cardiovascular disease has been widely investigated and evaluated as regards regional differences in cardiovascular disease. This study was performed to evaluate the relation between calcium and magnesium in drinking water and diet and risk factors for cardiovascular disease in individuals living in hard and soft water areas with considerable differences in cardiovascular mortality. Methods: A random sample of 207 individuals living in two municipalities characterised by differences in cardiovascular mortality and water hardness was invited for an examination including a questionnaire about health, social and living conditions and diet. Intake of magnesium and calcium was calculated from the diet questionnaire with special consideration to the use of local water. Household water samples were delivered by each individual and were analysed for magnesium and calcium. Results: In the total sample, there were positive correlations between the calcium content in household water and systolic blood pressure (SBP) and negative correlations with s-cholesterol and s-LDL-cholesterol. No correlation was seen with magnesium content in household water to any of the risk factors. Calcium content in diet showed no correlation to cardiovascular risk factors. Magnesium in diet was positively correlated to diastolic blood pressure (DBP). In regression analyses controlled for age and sex 18.5% of the variation in SBP was explained by the variation in BMI, HbAlc and calcium content in water. Some 27.9% of the variation in s-cholesterol could be explained by the variation in s-triglycerides (TG), and calcium content in water. Conclusions: This study of individuals living in soft and hard water areas showed significant correlations between the content of calcium in water and major cardiovascular risk factors. This was not found for magnesium in water or calcium or magnesium in diet. Regression analyses indicated that calcium content in water could be a factor in the complexity of relationships and importance of cardiovascular risk factors. From these results it is not possible to conclude any definite causal relation and further research is needed.
