Mental Health and Health Status of Elderly
Bengalis and Somalis in London
Age and Ageing

November 1995
A semi-structured questionnaire on mental and physical health including a
Life Satisfaction Index (LSI) and a scale of Symptoms of Anxiety and
Depression (SAD) was administered in appropriate languages to 75 Bengalis
and 72 Somalis aged 60 years and over living in Tower Hamlets, London. Data
on prevalence of health problems and disability were sought to explore the
relationships between health and socio-demographic determinants of anxiety
and depression and life satisfaction. Prevalence of chronic health problems
was correlated with SAD scores among Somalis (r = +0.31, p = 0.01) and
Bengalis (r = +0.38, p = 0.001) and LSI scores among Somalis (r = -0.25, p =
0.04) but not Bengalis (r = -0.05). Disability in activities of daily living
(ADL) correlated with LSI (r = -0.29, p = 0.01) and SAD scores (r = +0.39, p
= 0.001) among Bengalis but not Somalis (r = -0. 11 and +0.08 respectively).
Both age and chronic health problems were predictors of SAD scores among
Somalis and health problems only predicted LSI scores. Among Bengalis, age
and ADL disability were strong predictors of SAD scores whilst disability
only predicted LSI scores. These findings emphasize the importance of
aspects of physical health as determinants of psychological well-being among
elderly people in different cultures. Differences observed between groups
may reflect their concepts of disease, disability and well-being. A
qualitative study to explore these possibilities is currently under way
among Somalis and will allow further insights into the significance of these
constructs.
Introduction and aims
Some empirical studies suggest that quality of life in old age is largely
determined by health status [1-4]. The importance of good health to general
well-being seems to be even greater among people in lower socioeconomic
groups [5].
With the decline in physical abilities associated with old age,
disability (particularly reduced mobility) rather than prevalence of chronic
health problems tends to assume a more salient role in influencing
well-being and may be a better indicator of subsequent mortality [6-8].
Physical health status and mental health are clearly linked but the
relationship may be causally bi-directional. Increased prevalence of chronic
health problems may inhibit people from interacting with friends or family
members in leisure or work, restricting opportunities for boosting
satisfaction within these life domains and producing depression. Negative
emotions due to stressful life events may, on the other hand, lead to
physical symptoms, feelings of hopelessness and predispose to physical
illness through ill-understood mechanisms [9].
Among people aged 75+ in Britain, 62% of men and 72% of women are likely
to report at least one long-term illness [10]. Elderly people from minority
ethnic groups (60+) report even higher prevalence rates of long-term health
problems. Data from the 1991 Census have revealed this to be the case
particularly for Pakistanis, Bangladeshis and Afro-caribbeans compared with
the white population of the same age [11, 12].
Epidemiological studies in Britain have shown higher prevalence rates of
diabetes, hypertension, ischaemic heart disease and asthma among West
Indians and people from the Indian subcontinent [13], higher consultation
rates for general practitioner services [14, 15] and a high use of hospital
beds among `Asian' elderly people, with increased discharge rates for
cataract surgery, diabetes, gastrointestinal bleeding and asthma compared to
a white group [16]. Rates of admission to psychiatric hospitals,
particularly for schizophrenia, seem also to be related to ethnicity though
lack of intercultural awareness is one of the complex issues involved in
influencing such patterns [17-19].
The additional interplay of social difficulties such as poverty and poor
housing is likely to exacerbate the relationship between ethnicity and
health status. Although research in North London has revealed low levels of
mental disorders among elderly Gujarati people [20] compared with the white
population, it is hypothesized that the prevalence of mental disorders among
elderly people living in impoverished areas will be high. Preliminary
evidence suggested low health status and social circumstances of elderly
people in the Somali and Bengali communities in Tower Hamlets [21, 22]. This
study of elderly Bengalis and Somalis was carried out with two main aims: to
examine levels of physical and mental health, and to study the relationship
between them, focusing on the determinants of anxiety and depression and
life satisfaction.
Methods
Subjects - Somalis: Seventy-two people were contacted, 60 men and 12
women. Names were drawn from a list of elderly Somalis receiving meals
available from a Somali London Community Voluntary Organisation. The
response rate was 100%. Participants were scattered through all wards in the
borough but the majority were living in Poplar, Bow and Bethnal Green. Data
were collected by a male Somali community worker from 1991 to 1992.
Interviews were conducted in Somali.
