The role of different predictors in 20-year mortality among Krakow older citizens

Predictors of total mortality and their differential association on premature or late mortality in the SUN cohort

Several studies have tried to analyse the association between all-cause mortality and different risk factors, (especially those which are modifiable, such as smoking, diet or exercise), to develop public health preventive strategies. However, a specific analysis of predictors of premature and late mortality is needed to give more precise recommendations. Considering that there are risk factors which exert an influence on some diseases and not on others, we expect that, similarly, they may have a different impact depending on the timing of mortality, separating premature (≤65 years) from late mortality (>65 years). Thus, we prospectively followed-up during a median of 12 years a cohort of 20,272 university graduates comprising an ample range of ages at inception. Time-dependent, covariate-adjusted Cox models were used to estimate adjusted hazard ratios (HR) and their 95 % confidence intervals (CI) for each predictor. The strongest independent predictor of mortality at any age was physical activity which was associated with reduced risk of total, premature and late mortality (range of HRs when comparing the highest vs. the lowest level: 0.24 to 0.48). Specific strong predictors for premature mortality were smoking, HR: 4.22 (95 % CI: 2.42-7.38), and the concurrence of ≥2 metabolic conditions at baseline, HR: 1.97 (1.10-3.51). The habit of sleeping a long nap (≥30 min/d), with HR: 2.53 (1.30-4.91), and poor adherence to the Mediterranean Diet (≤3 points in a 0 to 8 score vs. ≥6 points), with HR: 2.27 (1.08-4.76), were the strongest specific predictors for late mortality. Smoking, diet quality or lifestyles, probably should be differentially assessed as specific predictors for early and late mortality. In the era of precision medicine, this approach will allow tailored recommendations appropriate to each person's age and baseline condition.

Older Adults Who Experience Their Lives to Be Completed and No Longer Worth Living: A Systematic Mini-Review Into Used Terminology, Definitions, and Interpretations

In the Netherlands and in Belgium, a political debate emerged regarding the possibility of euthanasia and assisted suicide (EAS) for older adults who experience their lives as completed and no longer worth living, despite being relatively healthy. This mini-review aimed to (1) present an overview of the terms used to denote this phenomenon as well as their definitions and to (2) explore how the underlying experiences are interpreted by the study authors. A systematic search was performed in Web of Science, MEDLINE, PsycINFO, and CINAHL, yielding 35 articles meeting the selection criteria. We selected empirical, English-language articles published in peer-reviewed journals. Participants had to have a first-person experience of the phenomenon or be assessed for it, or have a third-person experience of the phenomenon. Results show that the terms tiredness of life (ToL) and weariness of life (WoL) were used most frequently, also in the broader literature on suicidal expressions across the life span. Many studies mentioned operational definitions or synonyms rather than theoretical definitions. Moreover, inside the EAS debate, the term ToL was more common, its definition incorporated death wishes, and it was regularly framed existentially. Outside of this debate, the phenomenon was generally considered as a part of suicidal ideation distinct from death wishes, and its experience was often associated with underlying psychopathology. We discuss the need to establish consensus definitions and conclude that only a multidimensional view may be suitable to capture the complex nature of the phenomenon.

Self-rated health and its association with all-cause mortality of older adults in Poland: The PolSenior project

OBJECTIVES

Predictive effect of self-rated health (SRH) on mortality in older adults has been observed. The purpose of the study was to analyze this association in Poles aged 65+.

METHODS

Data were obtained from the nationwide, multidisciplinary PolSenior project, conducted in a representative sample of older population. The study group comprised 4049 respondents (48.0% women) without significant cognitive deficit. SRH was measured using Visual Analog Scale. The analysis included selected socio-economic, health status and life-style factors. Mortality data were retrieved from the state registry.

RESULTS

During 5-year period, 414 women (21.4%) and 672 men (31.8%) have died, including 17.5% of women and 26.6% of men with good, 21.6% and 32.9% with fair, 36.2% and 55.3% with poor SRH, respectively. Kaplan-Meier survival curves for SRH revealed significant differences for both genders. Univariate Cox regression analysis revealed significant hazard ratios (HRs) for mortality among women and men with poor compared to good SRH [2.48 (1.83-3.37); 2.62 (2.04-3.36), respectively] and those with fair compared to good SRH [1.29 (1.03-1.60); 1.29 (1.10-1.52), respectively]. Age-adjusted HRs for mortality were significant between groups with poor and good SRH [women: 1.98 (1.46-2.68), men: 2.06 (1.60-2.64)]. Multivariate Cox proportional hazard regression model including revealed significant HRs for mortality between women with poor and good SRH [1.67 (1.06-2.64)].

CONCLUSIONS

SRH was associated with mortality in both genders. After adjustment for age, this relationship was maintained in respondents with poor compared to good SRH. Inclusion of potential confounders demonstrated that SRH was an independent predictor of mortality only in women.

Quality of life and health care utilization in patients with chronic respiratory diseases

High quality of life (QoL) may reduce the costs of medical care of chronically ill patients due to lower health care utilization. The purpose of this study was to establish the influence of the QoL of primary care patients with chronic respiratory diseases on the level of health care utilization and the predictors of hospitalization. The study group consisted of 594 adult patients with chronic respiratory diseases of the mean age 59.8±14.9 years. The highest QoL was observed in the social relationship domain and the lowest in the physical domain. Low QoL was associated with a low level of health care utilization among patients with chronic respiratory diseases. Most patients were hospitalized during the past 3 years. In a group of patients with chronic respiratory diseases, chances for hospitalization were: higher among patients with low QoL and health satisfaction, low QoL levels in the physical and social relationship domains, high QoL levels in the psychological domain, those with higher education, residents of rural areas, patients using frequent consultations over the phone, and those with at least an average index of services.

Gardening as the dominant leisure time physical activity (LTPA) of older adults from a post-communist country. The results of the population-based PolSenior Project from Poland

OBJECTIVE

To describe the LTPA of older Polish citizens in the nationwide, representative population-based PolSenior Project.

METHODS

A study group comprising 4813 randomly recruited participants aged 65 and over was surveyed. Data concerning LTPA in relation to age, gender, place of residence, and social class have been reported.

RESULTS

Only 33.6% fulfilled the recommended LTPA criteria. Gardening (64.6%), walking (39.0%) and cycling (37.3%) were the most popular physical activities, followed by gymnastic exercises (18.2%) and dancing (12.8%). Village residents reported walking, gymnastics, swimming, tennis and dancing (32.5%, 9.1%, 1.8%, 0.1%, 8.1%) less frequently than those who live in cities, especially as compared to the residents of the largest cities (45.2%, 28.3%, 13.4%, 1.3%, 15.7%, respectively). However, the frequency of cycling generally decreased with the size of the place of residence. Village residents reported cycling and gardening more frequently (49.2% and 75.8%) than residents of the largest cities (20.6% and 45.8%, respectively).

CONCLUSION

There are several differences in the LTPA of older adults in Poland compared with those in North America or Western Europe. Community-based and environmental policies should concentrate on a combination of sustaining existing favorable physical activity (PA) habits (gardening and cycling), and developing access and motivation for participation in LTPA characteristic of developed countries.

Human immunodeficiency virus-associated obstructive lung diseases

In the era of effective antiretroviral therapy (ART), epidemiologic studies have found that persons infected with human immunodeficiency virus (HIV) have a higher prevalence and incidence of chronic obstructive pulmonary disease than HIV-uninfected persons. In comparison with HIV-uninfected persons and those with well-controlled HIV disease, HIV-infected persons with poor viral control or lower CD4 cell count have more airflow obstruction, a greater decline in lung function, and possibly more severe diffusing impairment. This article reviews the evidence linking HIV infection to obstructive lung disease, and discusses management issues related to the treatment of obstructive lung disease in HIV-infected patients.
