Subjective health and quality of life among elderly people living with chronic multimorbidity and difficulty in activities of daily living in rural South Africa

Background: South Africa has been experiencing a growing proportion of elderly population with rapid increases in the burden of non-communicable diseases (NCDs) characteristic of population aging. Rural areas in South Africa represent a far smaller fraction of the population, however, share a relatively higher burden of NCDs. In the current literature, there is limited evidence on rural studies in the context of chronic diseases and activities of daily living (ADLs) among the elderly population (60 years and above) in South Africa.

Purpose: In this regard, we undertook the present study with the objective of examining the demographic, behavioral, and socioeconomic predictors of subjective health, depression, and quality of life among elderly men and women living in the rural areas (n=2,627).

Methods: Data for this study were collected from the Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community in South Africa (HAALSI). Main explanatory variables were self-reported NCDs and difficulties in ADLs. The predictors of subjective health, depression, and quality of life were assessed using multivariable regression methods.

Results: We found that the proportion of participants who reported good health, not having depression, and good quality of life was respectively 44.7%, 81.3%, and 63%. Women in the oldest age group (80+ years) were significantly less likely to report good health (OR=0.577, 95% CI=0.420, 0.793) and quality of life (OR=0.709, 95% CI=0.539, 0.933) compared with those in the youngest group. Having more than one chronic condition and ADL difficulties significantly lowered the odds of good health, having no depression, and quality of life among men and women.

Conclusion: The present findings suggest the involvement of sociodemographic factors in health and quality of life outcomes among elderly South Africans, and call for enhanced efforts to address these health limiting conditions such as ADLs and chronic multimorbidity.

The culturally adapted Italian version of the Barthel Index (IcaBI): assessment of structural validity, inter-rater reliability and responsiveness to clinically relevant improvements in patients admitted to inpatient rehabilitation centers

The Barthel Index (BI) is widely used to determine eligibility criteria for inpatient rehabilitation and to monitor patients' recovery, irrespective of the illnesses that affect them. The culturally adapted Italian version of the Barthel Index (IcaBI) was recently validated. This paper reports the structural validity and inter-rater reliability of the IcaBI and its responsiveness to the results of inpatient rehabilitation. The IcaBI was administered to a cohort of 264 patients hospitalized in two rehabilitation centers in Rome, Italy. Factor analysis using principal component analysis revealed a monofactorial structure for neurological patients and, after removal of item 1 "feeding", also for orthopedic patients. Substantial to optimal inter-rater reliability was found (0.74 > intraclass correlation coefficient < 0.96). The IcaBI was found to be accurate (area under the curve= 0.72) with a minimal clinically important change score of 35 points. This work confirms that IcaBI is a useful tool for measuring disability in health and social care settings along the continuum of care. Further studies are needed to assess its criterion validity, interpretability and responsiveness in other specific disease conditions.
