Background During the past decades, declining trends in mean cholesterol levels and smoking have been observed in Western Europe, whereas obesity and a sedentary lifestyle have increased. ...Simultaneously, there has been a marked decrease in mortality from cardiovascular (CV) diseases. Methods The aim of the study was to determine whether these trends in CV risk factors continued over a period of 50 years. Six systematic or random population samples of 50-year-old men ( n = 3563) living in Gothenburg, Sweden, were investigated between 1963 and 2013. Results During the 50 years, mean body mass index (BMI) at 50 years of age increased by 2 kg/m
, from 24.8 kg/m
in 1963 to 26.8 kg/m
in 2013 ( p < 0.001). A decrease in systolic blood pressure of nearly 10 mmHg was observed from 1963 to 1993, but was not sustained through the past two decades. Mean serum cholesterol fell from 6.42 (SD 1.12) mmol/L to 5.34 (SD 0.97) mmol/L. The prevalence of smoking at 50 years of age decreased markedly from 56.1% in 1963 to 11.9% in 2013. The number of participants with a sedentary lifestyle during leisure time decreased until 1993, but has remained unchanged since. In 2013, 50-year-old men had a 6.9-times higher likelihood of lacking CV risk factors than 50-year-old men in 1963 (95% confidence interval (CI): 3.5-13.3, p < 0.001). The odds ratio for having four or more risk factors was only 0.13 (95% CI: 0.062-0.29, p < 0.001). Conclusion Despite increasing body weight, the total CV risk factor burden has decreased in 50-year-old men over the past 50 years.
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.
Several studies have shown a markedly higher mortality rate among disability pensioners than among non-retired. Since most disability pensions are granted because of non-fatal diseases the reason for ...the increased mortality therefore remains largely unknown. The aim of this study was to evaluate potential explanatory factors.
Data from five longitudinal cohort studies in Sweden, including 6,887 men and women less than 65 years old at baseline were linked to disability pension data, hospital admission data, and mortality data from 1971 until 2001. Mortality odds ratios were analyzed with Poisson regression and Cox's proportional hazards regression models.
1,683 (24.4%) subjects had a disability pension at baseline or received one during follow up. 525 (7.6%) subjects died during follow up. The subjects on disability pension had a higher mortality rate than the non-retired, the hazards ratio (HR) being 2.78 (95%CI 2.08-3.71) among women and 3.43 (95%CI 2.61-4.51) among men. HR was highest among individuals granted a disability pension at young ages (HR >7), and declined parallel to age at which the disability pension was granted. The higher mortality rate among the retired subjects was not explained by disability pension cause or underlying disease or differences in age, marital status, educational level, smoking habits or drug abuse. There was no significant association between reason for disability pension and cause of death.
Subjects with a disability pension had increased mortality rates as compared with non-retired subjects, only modestly affected by adjustments for psycho-socio-economic factors, underlying disease, etcetera. It is unlikely that these factors were the causes of the unfavorable outcome. Other factors must be at work.
Random samples of 50-year-old men living in Gothenburg have been examined every 10th year since 1963 with a focus on cardiovascular risk factors. The aims of the study were to acquire up-to-date ...information about risk factors in the fifth cohort of 50-year-old men and women, to re-examine those who were 50 years of age in 1993, and to analyse the prevalence of the metabolic syndrome (MetSyn) using different definitions.
A random sample of men and women born in 1953 were examined in 2003-2004 for cardiovascular risk factors. Men born in 1943 and that participated in the examination in 1993 were also invited. Descriptive statistics were calculated.
The participation rate among men and women born in 1953 was 60 and 67% respectively. Among men born in 1943, the participation rate was 87%. The prevalence of obesity was from 15 to 17% (body mass index, BMI >or= 30) in the three samples. The prevalence of known diabetes was 4% among the 50-year-old men and 6% among the 60-year-old men, and 2% among the women. Increased fasting plasma glucose varied substantially from 4 to 33% depending on cut-off level and gender. Mean cholesterol was 5.4 to 5.5 mmol/l. Smoking was more common among women aged 50 (26%) than among men aged 50 (22%) and 60 years (15%). The prevalence of the MetSyn varied with the definition used: from 10 to 15.8% among the women, from 16.1 to 26% among 50-year-old men, and from 19.9 to 35% among the 60-year-old men. Only 5% of the men and women had no risk factors.
This study provides up-to-date information about the prevalence of cardiovascular risk factors and the MetSyn in middle-aged Swedish men and women. Different definitions of the MetSyn create confusion regarding which definition to use.
The prevalence of cardiometabolic multimorbidity is increasing.
To estimate reductions in life expectancy associated with cardiometabolic multimorbidity.
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.
A history of 2 or more of the following: diabetes mellitus, stroke, myocardial infarction (MI).
All-cause mortality and estimated reductions in life expectancy.
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.
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.
Abstract Background Population-based study of a random sample of 50-year-old men and women in Gothenburg, Sweden. Objective To examine the determinants of perceived health and the differences between ...50-year-old men and women. Methods Men and women born in 1953 were examined between 2003 and 2004. Participation rate was 60% among the men and 67% among the women. Questionnaires were used, including one on perceived health that was ranked on a 7-point scale from 1 (excellent) to 7 (very poor). The participants' medical histories were obtained through a questionnaire, and risk factors were measured. Results Women generally perceived their health as poorer than men. Women experienced more symptoms than men, and most symptoms were more prevalent among women than men. Poor perceived health was strongly related to number of symptoms. In multivariable analyses 5 factors were related to perceived health in both men and women: working full or part time (women OR odds ratio = 0.3, men OR = 0.3) and physical activity (women OR = 0.6, men OR = 0.6) had a positive effect, whereas a low level of social activities (women OR = 1.9, men OR = 1.7), still feeling tired after normal hours of sleep (women OR = 4.5, men OR = 4.0), and feeling burned out during the past 12 months (women OR = 2.3, men OR = 3.0) had a negative effect on perceived health. Conclusions Women perceive their health as “worse” in comparison with men. Perceived health is a multifaceted condition related to social circumstances, physical activity, various symptoms, and tiredness after normal hours of sleep both in women and men.
Simple global self-ratings of health (SRH) have become increasingly used in national and international public health monitoring, and in recent decades recommended as a standard part of health ...surveys. Monitoring developments in population health requires identification and use of health measures, valid in relation to targets for population health. The aim of the present study was to investigate associations between SRH and sick leave, disability pension, hospital admissions, and mortality, adjusted for effects of significant covariates, in a large population-based cohort.
The analyses were based on screening data from eight population-based cohorts in southern and central Sweden, and on official register data regarding sick-leave, disability pension, hospital admissions, and death, with little or no data loss. Sampling was performed 1973-2003. The study population consisted of 11,880 women and men, age 25-99 years, providing 14,470 observations. Information on SRH, socio-demographic data, lifestyle variables and somatic and psychological symptoms were obtained from questionnaires.
There was a significant negative association between SRH and sick leave (Beta -13.2, p<0.0001, and -9.5, p<0.01, in women and men, respectively), disability pension (Hazard ratio 0.77, p<0.0001 and 0.76, p<0.0001, in women and men, respectively), and mortality, adjusted for covariates. SRH was also significantly associated with hospital admissions in men (Hazard ratio 0.87, p<0.0001), but not in women (Hazard ratio 0.96, p0.20). Associations between SRH on the one hand, and sick leave, disability pension, hospital admission, and mortality, on the other, were robust during the follow-up period.
SRH had strong predictive validity in relation to use of social insurance facilities and health care services, and to mortality. Associations were strong and robust during follow-up.
End-stage renal disease is associated with a high risk of cardiovascular events. It is unknown, however, whether mild-to-moderate kidney dysfunction is causally related to coronary heart disease ...(CHD) and stroke.
Observational analyses were conducted using individual-level data from 4 population data sources (Emerging Risk Factors Collaboration, EPIC-CVD European Prospective Investigation into Cancer and Nutrition-Cardiovascular Disease Study, Million Veteran Program, and UK Biobank), comprising 648 135 participants with no history of cardiovascular disease or diabetes at baseline, yielding 42 858 and 15 693 incident CHD and stroke events, respectively, during 6.8 million person-years of follow-up. Using a genetic risk score of 218 variants for estimated glomerular filtration rate (eGFR), we conducted Mendelian randomization analyses involving 413 718 participants (25 917 CHD and 8622 strokes) in EPIC-CVD, Million Veteran Program, and UK Biobank.
There were U-shaped observational associations of creatinine-based eGFR with CHD and stroke, with higher risk in participants with eGFR values <60 or >105 mL·min
·1.73 m
, compared with those with eGFR between 60 and 105 mL·min
·1.73 m
. Mendelian randomization analyses for CHD showed an association among participants with eGFR <60 mL·min
·1.73 m
, with a 14% (95% CI, 3%-27%) higher CHD risk per 5 mL·min
·1.73 m
lower genetically predicted eGFR, but not for those with eGFR >105 mL·min
·1.73 m
. Results were not materially different after adjustment for factors associated with the eGFR genetic risk score, such as lipoprotein(a), triglycerides, hemoglobin A1c, and blood pressure. Mendelian randomization results for stroke were nonsignificant but broadly similar to those for CHD.
In people without manifest cardiovascular disease or diabetes, mild-to-moderate kidney dysfunction is causally related to risk of CHD, highlighting the potential value of preventive approaches that preserve and modulate kidney function.
