Canberra, Philadelphia and Manchester, Feb 20 (IPS) – Old age is often characterised by poor health due to isolation, morbidities and disabilities in carrying out activities of daily living (DADLs) leading to depression.
Mental disorders—in different forms and intensities— affect most of the population in their lifetime. In most cases, people experiencing mild episodes of depression or anxiety deal with them without disrupting their productive activities. A substantial minority of the population, however, experiences more disabling conditions such as schizophrenia, bipolar disorder type I, severe recurrent depression, and severe personality disorders. While common mild disorders are amenable to self-management and relatively simple educational or support measures, severe mental illness demands complex, multi-level care that involves a longer-term engagement with the individual, and with the family.
Yet, despite the considerable burden and its associated adverse human, economic, and social effects, governments and donors have failed to prioritise treatment and care of people with mental illness. Indeed, pervasive stigma and discrimination contributes to the imbalance between the burden of disease due to mental disorders, and the attention these conditions receive.The percentage of the population aged 60 years and above in South Africa rose from 7.1% in 1996 to 8 % in 2011, an increase from 2.8 million to 4.1 million individuals.
The proportion of persons 60 years and older is projected to almost double during 2000–2030 because of (i) a marked decline in fertility in the past few decades; (ii) the HIV and AIDS pandemic contributing to this change in the population structure, with a higher mortality of young adults, especially women of reproductive age; and (iii) a rise in life expectancy to 62 years in 2013-– a staggering increase of 8.5 years since the low in 2005.Four in ten elderly persons in South Africa are poor.
More than a third make an average living, and the rich constitute about 27%. Provincial variations show that rural provinces have higher proportions of poor elderly persons compared to those residing in the urban provinces. Racial differences show that elderly Whites and Indians/Asians occupied a higher socio-economic status than black Africans and Coloureds.
Ours is the first study that offers a comprehensive analysis of depression among the old (60+ years) in South Africa, using the four waves of the National Income Dynamics Study (SA-NIDS) (2008, 2010, 2012 and 2014).A self-reported measure of depression is used. SA-NIDS gives data on not depressed in a week, depressed for 1-2 days, 3-4 days and 5-7 days. We focus on those depressed for ≥ 3 days in a week. Referring to this as a measure of severe depression, its prevalence reduced from 15.3 % among the old in 2008 to 14.5 % in 2014, with a dip to 12.6 % in 2012.Aging is a major factor in depression. Those in early 60s are generally more depressed than older persons in their 70s and 80s.
Old women were consistently more depressed than old men, as they are subject to violence. It is associated with conflicts over the man’s drinking, the woman having more than one partner, and her not having post-school education. Another factor is that women are typically much more likely to be overweight and obese, leading to non-communicable diseases (NCDs) and subsequently higher depression.
A challenging aspect of obesity prevention among black South Africans is the positive perception that both women and men attach to a large body size.Married men and women are less depressed than others. Marriage thus serves as a barrier to loneliness and a source of support during periods of stress for old persons. However, old persons in larger households without any other old person are more prone to depression. It is not clear whether larger households result in neglect of old persons or their abuse.
Ethnicity matters. The Africans are more prone to depression than the reference group of the Whites and Coloureds. There is limited evidence suggesting that Asians / Indians / Others are less likely to be depressed.
Pensioners are less likely to be depressed despite some evidence in the literature on pooling of pensions with other household resources and denying the pensioner any financial autonomy. Although this can’t be ruled out, it is evident that the favourable effect of pensions in preventing depression is robust.
Of particular significance are the results on multimorbidity (more than one disease at a time). Two combinations of NCDs (diabetes and high BP, and cancer and heart disease) are positively associated with depression. Equally important are the associations between disabilities in activities of daily living or DADLs (e.g. difficulties in dressing, bathing, eating, walking, climbing stairs) and depression. In many cases, both sets of DADLs are positively associated with depression. The relationship between depression and body mass index or BMI categories (underweight…
