  Abstract 


Introduction: One of the most important indicators of health and well being of the elderly is the quality of life they live in. Owing to the rise in elderly population due to the demographic transition, there is growing need to address the health concerns of this population. Aims: The study was undertaken to find out the Quality of Life among the elderly and the associated factors. Methodology: This is a descriptive cross sectional study done in urban area of Thiruvallur district Tamil Nadu. To arrive at the required sample of 199, elderly people above 60 years were selected by probability proportionate to size sampling. Semi-structured pre-tested questionnaire was used for data collection regarding sociodemographic details and related factors. Katz scale was used to assess activities of daily living and Quality of life (QOL) was assessed using WHO quality of life BREF (WHOQOL BREF) questionnaire. Results: Moderate score in QOL was obtained in all the 4 domains with highest in Psychological and environmental domains. Nearly 99% of had full activity in Katz scale. All the three QOL domains were found to have statistical significant association with age and education.

  Introduction Top


According to United Nations elderly or older persons are the people aged 60+ years. They are further classified as oldest old (80+ years), centenarian (100+) and super-centenarian (110+). The population of elderly is expected to reach 1.2 billion by 2025 globally.[1] By the year 2020, the total number of elderly will nearly be more than the children under 5 years of age. All of the countries face a major challenge in facing this demographic shift.

Around 8% of the total population of India belong to elderly age group. This is expected to increase to 12.4% of the total population by 2026. About 65% of the elderly people in India have the need to be dependant on others for their daily needs.[2] A decrease in the fertility rates and increased survival rates has led to dramatic increase in the elderly population. This shft is posing major challenges among various interconnected fields of health mainly the massive challenge of growth of the burden and impact of non-communicable diseases (NCDs) among the elderly population.[3]

WHO defines quality of life as “An individual's perception of life in the context of culture and value system in which he or she lives and in relation to his or her goals, expectations, standards and concerns”.[4] Thus, it covers the individual's mental health, physical health, degree of independence, attachment to surroundings, individual beliefs and their connection with the environment.[5] To complement the growing burden of NCDs, the four major risk factors of chronic disease namely, obesity, tobacco, physical inactivity and alcohol consumption are particularly of concern in older Indian adults especially among those who live a lower quality of life. Another growing challenge which determines the quality of life among elderly is housing security and income of older adults. India is country where elders are not only economically dependant on the children but also have psychological dependence on them. But due to rapid modernization and urbanization, there is growing transition from joint/three generation to nuclear families, the elders are becoming deprived of the care and affection they receive from their kids and grandkids. They tend to feel isolated, stressed and depressed which could reduce their quality of life putting them at risk of developing various risk factors of NCDs which can significantly afftect their mortality and morbidity.[3]

There is paucity of data on community based research done to assess the quality of life of elderly in Tamilnadu. Therefore, this study is aimed to find out the quality of life of elderly individuals in selected urban field practice area of a private medical college in Tamilnadu and to find out various factors associated with quality of life among them.

  Discussion Top


Quality of life is one of the major determinants of healthy living among the elderly. All of the major non-communicable diseases like diabetes, hypertension and even cancer has an important psychsocial component which is responsible for proper control and prognosis which depends on the quality of life they live. This study done in an urban population gave interesting results which are discussed below.

In this study, most of the participants were in the age category of 60-69 years, followed by 70-79 years and >80 years. Similar results were present in various studies like Raj D et al. in Varanasi, Elango S et al. in rural Tamil Nadu and Durgawale PM et al.[7],[8],[9] Nearly 50% of the participants were belonging to joint family system in the present study. Similar results were found in study conducted by Lena et al. Karnataka[10] and Durgawale et al. in Karad.[9] These findings may be due to the high prevalence of joint family tradition in the country. Majority of them were economically dependent on their family (66%). Similar findings were observed in study done by Sowmiya KR et al.[11]

Regarding self reported morbidity among the study participants, hypertension and diabetes mellitus was the common health conditions encountered in this study. Similar results were found in study done by Ganesh Kumar S et al. in Puducherry.[12] where diabetes mellitus had higher prevalence when compared to other co- morbid conditions. These health problems can influence and affect their Quality of Life as these chronic diseases can affect the physical and psychological wellbeing of the individuals as evident from the study done by Joshi MR et al.[13]

In our study the mean score of QOL in the physical domain was similar to study done by Ganesh Kumar S et al. in Puducherry[12] but mean score of QOL in social relationship domain had significan difference in the values. The difference observed in different domains may be due to difference in pattern of associated factors which influence QOL in different study setting. Definition and instruments used to assess QOL may be the other factor responsible for this difference.

Psychological domain in our study is similar to study in Mudey A et al. Maharashtra.[14] Mean score of social relationship in our study is similar to study by Sowmiya KR et al.[11] where mean was 63.69. This indicates that their social contacts and support they derive from their personal relations and peer groups has greater influence on them.

In our study marital status was significantly associated with psychological but study in Kuala Lumpur by Onunkwor OF et al.[15] found no significance association to domain of QOL may be due to the reason that study was conducted in old age homes where they don't live with their spouse. As study in Mettupalayam by Sowmiya KR et al.[11] showed no significant difference between psychological and marital status.The difference may be due to the reason that majority in our study were married and living with spouse and is a different study group when compared to other studies.

In our study level of education was significantly associated with psychological domain and was also significantly associated with environmental domain similar to study done in Kula lumpur by Onunkwor OF et al.[15] This may be due to that level of education may be linked with psychological resilience, coping mechanism and social relationships.

In our study we found that socioeconomic status was not significantly associated with all the four domains of QOL. But study in Kula lumpur by Onunkwor OF et al.[15] and Ghosh D et al.[16] socioeconomic status found significant with all domains of QOL. In a study done by Ghosh D et al., This may be due to different classification (B.G. Prasad) was used in our study and other factors playing more important role than socioeconomic status.

Since the elderly frequently visit primary health centers and family physicians for their health needs, it is imperative that the treating primary physicians should be made aware of assessing the quality of life among elderly patients so that they can deliver holistic healthcare treatment to the person rather than treating the disease or illness alone. WHO Quality of Life questionnaire must be in used by all primary care physicians especially among those elderly who suffer from chronic diseases, so that the major domains which has an impact on their quality of life can be found out and counselling, Focus Group Discussions (FDG) and Health education activities can be carried out among them.

This study among elderly people in Thirumazhisai has found moderate QOL score all of the domains. Similar results were obtained in developed countries like Europe where the QOL scores were found to be acceptable (56.6%) as found in a study done by Grassi L et al.[17] Among the domains, psychological and environmental domains had highest QOL scores. Age, sex, education, marital status, employment status and role in family are the factors which were found to have statistical significant association with quality of life among the elderly.


  Conclusion Top


This study highlights the fact that, the elderly need the ardent support from the family and social circle which could help in improving the quality of life and help them to lead a physically, socially and economically productive life. Health education programmes can be implemented in the form of social support groups for the elderly with weekly Focus Group Discussions among them with a psychologist/counselor to find out the gaps in the QOL domains and measures could be taken to address them.
