BackgroundMultimorbidity is increasingly recognized as a major public health challenge of modern societies. However, knowledge about the size of the population suffering from multimorbidity and the type of multimorbidity is scarce. The objective of this study was to present an overview of the prevalence of multimorbidity and comorbidity of chronic diseases in the Dutch population and to explore disease clustering and common comorbidities.MethodsWe used 7 years data (2002–2008) of a large Dutch representative network of general practices (212,902 patients). Multimorbidity was defined as having two or more out of 29 chronic diseases. The prevalence of multimorbidity was calculated for the total population and by sex and age group. For 10 prevalent diseases among patients of 55 years and older (N = 52,014) logistic regressions analyses were used to study disease clustering and descriptive analyses to explore common comorbid diseases.ResultsMultimorbidity of chronic diseases was found among 13% of the Dutch population and in 37% of those older than 55 years. Among patients over 55 years with a specific chronic disease more than two-thirds also had one or more other chronic diseases. Most disease pairs occurred more frequently than would be expected if diseases had been independent. Comorbidity was not limited to specific combinations of diseases; about 70% of those with a disease had one or more extra chronic diseases recorded which were not included in the top five of most common diseases.ConclusionMultimorbidity is common at all ages though increasing with age, with over two-thirds of those with chronic diseases and aged 55 years and older being recorded with multimorbidity. Comorbidity encompassed many different combinations of chronic diseases. Given the ageing population, multimorbidity and its consequences should be taken into account in the organization of care in order to avoid fragmented care, in medical research and healthcare policy.
Even in old age, participation in activities with at least a medium-low intensity may postpone cognitive decline. Moreover, a decrease in duration or intensity of physical activity results in a stronger cognitive decline than maintaining duration or intensity.
A moderate intake of EPA+DHA may postpone cognitive decline in elderly men. Results from other studies are needed before definite conclusions about this association can be drawn.
Objective: To investigate whether coffee consumption is associated with 10-year cognitive decline in elderly men, as results of previous studies obtained hitherto have been controversial and prospective information on this association has been lacking. Design, subjects and setting: Six hundred and seventy six healthy men born between 1900 and 1920 from Finland, Italy and the Netherlands participated in a 10-year prospective cohort study. Cognitive functioning was assessed using the Mini-Mental State Examination (0-30 points, with a higher score indicating better cognitive performance). Coffee consumption was estimated in cups per day. A mixed longitudinal model was used to investigate the association between baseline coffee consumption and 10-year cognitive decline. Multiple adjustments were made. Results: Men who consumed coffee had a 10-year cognitive decline of 1.2 points (4%). Non-consumers had an additional decline of 1.4 points (Po0.001). An inverse and J-shaped association was observed between the number of cups of coffee consumed and cognitive decline, with the least cognitive decline for three cups of coffee per day (0.6 points). This decline was 4.3 times smaller than the decline of non-consumers (Po0.001). Conclusions: Findings suggest that consuming coffee reduces cognitive decline in elderly men. An inverse and J-shaped association may exist between the number of cups of coffee consumed and cognitive decline, with the least cognitive decline for men consuming three cups of coffee per day.
We investigate the association between marital status and living situation (over 5 years) on 10-year subsequent cognitive decline. The study population consisted of 1,042 men aged 70-89 years in 1990, who participated in the longitudinal Finland, Italy, the Netherlands Elderly (known as FINE) Study. We measured cognition by using the Mini-Mental State Examination, and we assessed marital status (married vs unmarried) and living situation (living with others vs living alone) with a standardized questionnaire. We performed repeated measurement analyses and made adjustments for age, education, country, smoking, alcohol, chronic diseases, marital status or living situation, and baseline cognition. Men who lost a partner, who were unmarried, who started to live alone, or who lived alone during the 5-year period had at least a two times stronger subsequent cognitive decline compared with men who were married or who lived with someone in those years.
To postpone cognitive decline and dementia in old age, primary prevention is required earlier in life during middle age. Dietary components may be modifiable determinants of mental performance. In the present study, habitual fruit and vegetable intake was studied in association with cognitive function and cognitive decline during middle age. In the Doetinchem Cohort Study, 2613 men and women aged 43-70 years at baseline (1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002) were examined for cognitive function twice, with a 5-year time interval. Global cognitive function and the domains memory, information processing speed and cognitive flexibility were assessed. Dietary intake was assessed with a semi-quantitative FFQ. In multivariate linear regression analyses, habitual fruit and vegetable intake was studied in association with baseline and change in cognitive function. Higher reported vegetable intake was associated with lower information processing speed (P¼0·02) and worse cognitive flexibility (P¼ 0·03) at baseline, but with smaller decline in information processing speed (P, 0·01) and global cognitive function (P¼0·02) at follow-up. Total intakes of fruits, legumes and juices were not associated with baseline or change in cognitive function. High intakes of some subgroups of fruits and vegetables (i.e. nuts, cabbage and root vegetables) were associated with better cognitive function at baseline and/or smaller decline in cognitive domains. In conclusion, total intake of fruits and vegetables was not or inconsistently associated with cognitive function and cognitive decline. A high habitual consumption of some specific fruits and vegetables may diminish age-related cognitive decline in middle-aged individuals. Further research is needed to verify these findings before recommendations can be made.
BackgroundWidening of socioeconomic status (SES) inequalities in smoking prevalence has occurred in several Western countries from the mid 1970’s onwards. However, little is known about a widening of SES inequalities in smoking consumption, initiation and cessation.MethodsRepeated cross-sectional population surveys from 2001 to 2008 (n ≈ 18,000 per year) were used to examine changes in smoking prevalence, smoking consumption (number of cigarettes per day), initiation ratios (ratio of ever smokers to all respondents), and quit ratios (ratio of former smokers to ever smokers) in the Netherlands. Education level and income level were used as indicators of SES and results were reported separately for men and women.ResultsLower educated respondents were significantly more likely to be smokers, smoked more cigarettes per day, had higher initiation ratios, and had lower quit ratios than higher educated respondents. Income inequalities were smaller than educational inequalities and were not all significant, but were in the same direction as educational inequalities. Among women, educational inequalities widened significantly between 2001 and 2008 for smoking prevalence, smoking initiation, and smoking cessation. Among low educated women, smoking prevalence remained stable between 2001 and 2008 because both the initiation and quit ratio increased significantly. Among moderate and high educated women, smoking prevalence decreased significantly because initiation ratios remained constant, while quit ratios increased significantly. Among men, educational inequalities widened significantly between 2001 and 2008 for smoking consumption only.ConclusionsWhile inequalities in smoking prevalence were stable among Dutch men, they increased among women, due to widening inequalities in both smoking cessation and initiation. Both components should be addressed in equity-oriented tobacco control policies.
