- The links between health-related behaviors and life satisfaction in elderly individuals who prefer institutional living

Subjects

This cross-sectional study was conducted as part of 'The Active Aging Project – Istanbul', funded by the Istanbul Greater Municipality. One hundred and thirty-three residents of the Municipality's Darulaceze Institute (48 females and 85 males, mean age 73.9 ± 8.0 [range: 60–90 yrs]) took part in the study. Elderly citizens with functional disabilities and/or independent in ADL are accepted by the Institute, which is located in Istanbul, the largest city in the country with a population of 10,072,447, constituting 16.02% of the total population, and has the largest bedding capacity of all such institutions in the country, as well as the largest professional staff including physicians, physical therapists, social workers, psychologists, nurses and nursing assistants and non-professional staff. Darulaceze Institute can be defined as 'Elderly Care and Rehabilitation Centers' according to institutional care system for elderly.

The following were the inclusion criteria for our study:

1. a stable medical condition;

2. not being bedridden or in a wheelchair;

3. independence in performing daily living activities (independence in walking indoors/outdoors, climbing up stairs, doing self care activities including taking a bath, feeding, dressing/undressing, were evaluated by self-reporting),

4. sufficient mental capacity and cognitive function to learn and retain new information;

5. willingness to participate in the study.

Functionally independent subjects were selected in order to collect accurate information from the prepared questionnaire and life satisfaction index.

All the participants and institution staff were informed about the objectives and methodology of the study, and the study plan was approved by the Ethics Committee of Marmara University. The participants were evaluated by institution's physicians before the study started. Individuals who had histories of significant cardiovascular, pulmonary, metabolic and/or musculo-skeletal diseases and/or psychiatric disorders were excluded. Among the 145 residents, 133 were eligible for the study, the participation rate being 92%. There were no internal dropouts during the study.

Data were collected during face-to-face interviews. The socio-demographic characteristics, health-related behaviors, leisure-time activities and fall histories of the participants were evaluated using a structured questionnaire.

The socio-demographic characteristics of the subjects were coded as follows: gender (female = 1; male = 2); marital status (1 = never married, divorced, widow/widower; 2 = married); level of education (1 = no education, 2 = primary school, 3 = high school, 4 = college/university); social security (1 = yes, 2 = no); and number of children. Income status was classified according to the participants' self-assessment.

Physical activity (walking, callisthenic exercises) were assessed in terms of frequency (sessions per week) and duration (minutes per session). Participants undertaking physical activity at least 3 times in a week with at least 30 minutes per session were classified as physically active, while the rest were classified as physically inactive.

Smoking habits were classified as 'current', 'ex-', and 'non-smoker'. Alcohol use was classified into four categories; abstainers, infrequent drinkers, moderate drinkers (1 or 2 glasses a day) and excessive drinkers (more than 2 glasses a day).

Any participant who had had at least one fall during the past year was considered to have a 'positive' fall history.

The frequency of leisure time activities (handicrafts, reading, gardening etc.) was categorized as " always", "frequently", "sometimes", "rarely" or "never". Participants who took part in leisure-time activities "always" or "frequently" were recorded as having regular leisure-time activities.

Life satisfaction was assessed by the LSI-A satisfaction index, which was first prepared, validated and published by Neugarten et al. [32] and was adapted and translated into Turkish by Karatas in 1988 as a highly reliable and valid index for the Turkish elderly population [33,34]. The internal consistency reliability coefficient (Cronbach's alpha) was computed at 0.66 for LSI-A in our study group, which was slightly below the lowest acceptable level (< 0.70). The LSI-A comprised twenty items, of which twelve were positively worded. The answers "disagree", "don't know" and "agree" were assigned as 0, 1 and 2 points respectively. Eight items were negatively worded, with 0 assigned to the "agree" answer. The total score obtainable from the LSI-A ranged between 0 and 40 points.

The collected data were analyzed using the SPSS 11.5 software package. Parametric tests of significance such as analysis of variance (ANOVA) and unpaired t tests were used for group comparisons. Linear regression models were constructed to determine LSI-A predictors. The variables which were found to be significantly related to LSI-A by univariate analysis, income level, regular physical and leisure time activity, were included in a multivariate analysis. The critical value for significance in all analyses was 0.05 (p < 0.05).
