Clinical characteristics and positive airway pressure adherence among elderly European sleep apnoea patients from the ESADA cohort.

Background: The prevalence of obstructive sleep apnoea (OSA) is growing as the population is ageing. However, data on the clinical characteristics of elderly patients with OSA and their adherence to positive airway pressure (PAP) treatment are scarce. Methods: Data from 23 418 30-79-year-old OSA patients prospectively collected into the ESADA database during 2007-2019 were analysed. Information on PAP use (h·day-1) in association with a first follow-up visit was available for 6547 patients. The data was analysed according to 10-year age groups. Results: The oldest age group was less obese, less sleepy and had a lower apnoea-hypopnoea index (AHI) compared with middle-aged patients. The insomnia phenotype of OSA was more prevalent in the oldest age group than in the middle-aged group (36%, 95% CI 34-38 versus 26%, 95% CI 24-27, p<0.001). The 70-79-year-old group adhered to PAP therapy equally well as the younger age groups with a mean PAP use of 5.59 h·day-1 (95% CI 5.44-5.75). PAP adherence did not differ between clinical phenotypes based on subjective daytime sleepiness and sleep complaints suggestive of insomnia in the oldest age group. A higher score on the Clinical Global Impression Severity (CGI-S) scale predicted poorer PAP adherence. Conclusion: The elderly patient group was less obese, less sleepy, had more insomnia symptoms and less severe OSA, but were rated to be more ill compared with the middle-aged patients. Elderly patients with OSA adhered to PAP therapy equally well as middle-aged patients. Low global functioning (measured by CGI-S) in the elderly patient predicted poorer PAP adherence.

Prognosis of acute coronary events is worse in patients living alone: the FINAMI myocardial infarction register.

BACKGROUND: Single living has been associated with a worse prognosis of acute coronary syndrome (ACS). We aimed to study the relation of sociodemographic characteristics to the morbidity, mortality, and case fatality (CF) of ACS in a large population-based ACS register. METHODS: The population-based FINAMI myocardial infarction register recorded 15,330 cases of ACS among persons aged 35-99 years in Finland in 1993-2002. Record linkage with the files of Statistics Finland provided information on sociodemographic characteristics (marital status, household size). RESULTS: ACS incidence and 28-day mortality rate were higher in unmarried men and women in all age groups. The prehospital CF of incident ACS was higher in single living and/or unmarried 35-64-year-old people. The 28-day CF was 26% (95% confidence interval, CI, 24-29%) in married men, 42% (95% CI 37-47%) in men who had previously been married, and 51% (95% CI 46-57%) in never-married men. Among women, the corresponding figures were 20% (95% CI 15-24%), 32% (95% CI 25-39%), and 43% (95% CI 31-56%). Most of these CF differences were apparent already at the prehospital phase. The only difference in treatment was that middle-aged men living alone or unmarried received thrombolysis less often. The disparities in ACS morbidity and mortality by marital status tended to widen during the study period. CONCLUSIONS: Single living and/or being unmarried increases the risk of having a heart attack and worsens its prognosis both in men and women regardless of age. Most of the excess mortality appears already before the hospital admission and seems not to be related to differences in treatment of ACS.

Socioeconomic inequalities in the morbidity and mortality of acute coronary events in Finland: 1988 to 2002.

PURPOSE: To examine the changes in socioeconomic disparities in the incidence of coronary heart disease (CHD) and mortality in Finland and to analyze the effects of the severe economic recession of the early 1990s on these disparities. METHODS: The population-based FINAMI Myocardial Infarction (MI) register recorded all suspected MI events among men and women ages 35 to 99 years in four geographical areas of Finland. Record linkage with the files of Statistics Finland provided us with detailed information on the indicators of socioeconomic status (SES; income, education, and profession). Rates were expressed per 100,000 inhabitants of each socioeconomic group per year and age-standardized to the European standard population. Poisson regression was used for analyzing rate ratios and time trends of coronary events in different socioeconomic groups. RESULTS: The mortality rate ratio of coronary events among 35- to 64 year-old men was 5.21 (95% confidence interval, 4.23-6.41) when the lowest income sixth to the highest income sixth were compared. Among women, the respective rate ratio was 11.13 (5.77-21.45). Significant differences in the incidence and 28-day mortality by SES were seen also in the older age groups. Some socioeconomic differences were found in the proportions of patients receiving thrombolysis or undergoing early revascularization. No substantial changes were observed in inequalities between the socioeconomic groups during the study period. CONCLUSIONS: The excess CHD morbidity and mortality among persons with lower SES is still considerable in Finland, but the economic recession did not widen the differences.

Myocardial infarction events and cardiovascular risk factor levels in Finnish- and Swedish-speaking populations of Finland.

BACKGROUND. The Swedish-speaking minority of Finland is unique, because it has a higher socioeconomic status (SES) and longer life expectancy than the Finnish-speaking majority. We hypothesized that this minority may have a lower attack rate of coronary events and analysed whether this could be explained by their higher SES. METHODS. The population-based myocardial infarction (MI) registers recorded 4,845 MI events in Turku during 1988-1998. Individual-level indicators of SES were obtained from Statistics Finland. The population-based FINRISK surveys recorded cardiovascular risk factors and native languages of 10,432 people in 1987, 1997, and 2002. RESULTS. The age-standardized attack rate of MI was lower among the 35-64-year-old Swedish-speaking men than among Finnish-speaking men (rate ratio 0.66; 95% confidence interval 0.47-0.85) and the difference remained significant after adjustment for SES. The Swedish-speaking inhabitants had higher age-, sex-, and SES-adjusted high-density lipoprotein cholesterol, and lower triglycerides, body mass index, and diastolic blood pressure. Conclusion. The Swedish-speaking inhabitants of Turku had lower MI morbidity and coronary mortality than the Finnish-speaking inhabitants. After controlling for SES, these differences remained significant among men, suggesting that other factors, such as differences in the risk factor profiles may also play a role.

Stroke morbidity in Swedish- and Finnish-speaking populations of Turku, Finland.

OBJECTIVES: To examine differences in the morbidity and mortality of stroke between the Finnish- and Swedish-speaking populations in Turku, taking into account the socioeconomic differences between these groups. DESIGN: The population-based FINMONICA and FINSTROKE stroke registers recorded 5,135 stroke events among persons aged 25-99 years in Turku during 1988-1998. Events in persons aged > or =75 years were not registered in 1993-1995. Information on these persons' native language and socioeconomic status (SES) (measured by taxable income, profession and years of education) were obtained by record linkage with the files of Statistics Finland. RESULTS: Swedish-speaking men had a lower attack rate of ischaemic stroke than Finnish-speaking men (270, 95% Confidence Interval (CI) 214-326 versus 370, 95% CI 352-389, per 100,000 inhabitants per year) and the difference remained significant after adjustment for SES. Among women, the attack rates of ischaemic stroke were similar in both language groups. CONCLUSIONS: The attack rate of ischaemic stroke was lower among Swedish-speaking than among Finnish-speaking men. This difference was not totally explained by the higher SES of the Swedish-speaking population.
