Received Date: Sep 24, 2015 / Accepted Date: Nov 02, 2015 / Published Date: Nov 09, 2015
Background: Healthcare is a great predictor of increased longevity and well-being but there is paucity of data on the prevalence of and socioeconomic differences in care need among the aged in low- to middle- income countries including Ghana.
Objective: The goal of this study is to provide timely research based knowledge of the socioeconomic differences in the prevalence of care need among older persons in Ghana which will be crucial in guiding the implementation of the 2010 National Aging Policy (Ghana National Ageing Policy, 2010).
Method: The World Health Organization (WHO) Study on global AGEing and Adult Health (SAGE) conducted in 2007-2008 among older adult Ghanaians included sociodemographic and socioeconomic factors and measures of health care needed by these older persons. This study considered 2313 (51.9%) men and 2141 (48.1%) women. Analyses of the association of care need with predisposing and enabling factors was by binary logistic regression analysis, using odds ratios (OR) and the respective 95% confidence intervals.
Results: This study showed sex differentials in care need among older persons. Older women were more affected by socioeconomic difference in care need. Older persons with lower education had a high prevalence of care need (for both men and women). Self-employed older persons were the highest in terms of care need and those with moderate, little or no money for daily living showed high rates of care need compared to those who had enough money.
Conclusion: Implementation of the 2010 national aging policy should address these gender disparities and socioeconomic differences in care need among older persons in Ghana.

Care is provided in the community to help people who may need it and support to maintain their independence. The need for longterm care arises from various causes, including diseases, disabling chronic conditions, injury, severe mental illness, and developmental disabilities. Generally, community care services are available to people adversely affected by illness, disability, old age, alcohol or drug related problems. In estimating the number of people with long-term care needs, researchers usually define a person as needing long term care if he or she requires another person’s help with one or more activities of daily living (ADLs) or instrumental activities of daily living (IADLs) . ADLs are fundamental tasks, defined here to include bathing, eating, dressing, using the toilet, getting in and out of a bed or chair, and getting around inside the home. IADLs are additional activities necessary for independence, such as meal preparation, managing money, managing medications, using the telephone, doing light housework, and shopping for groceries and other necessities. The proportion of older people is increasing in almost all countries of the world and Ghana is no exception . This is due to population ageing, a demographic trend in which there is a decline in both birth rate and death rate in a population . With an increase in life expectancy, adults will continue to live to the “ripe” old age.
Post retirement period is associated with physical and social challenges. Within an economic and political context, retirement ages and the ages at which individuals become eligible for aged-related benefits are determined based on different criteria. Official retirement ages have steadily increased and there are significant variations between countries for official retirement ages, and between sexes. In China, for example, the retirement age is generally around 60 years for men and 50–55 years for women respectively; however, in some labor-intensive jobs, it may be 5 years earlier . Special health care needs include any physical, developmental, mental, sensory, behavioral, cognitive, or emotional impairment or limiting condition that requires medical management, health care intervention, and/or use of specialized services. Population ageing is a global phenomenon, affecting both developed and developing nations, with attendant implications for health policy and future systems of care. Older individuals are living for much longer, with a significant burden of chronic disease, disability and impairments in cognition, sight, hearing and mobility. Despite this, the bulk of evidence at present seems to indicate that the onset of disability is being postponed, supporting the notion of the “compression of morbidity” . The capacity to meet the healthcare needs of an increasingly older adult population represents a significant challenge for public health globally. Many of the oldest-old lose their ability to live independently because of limited mobility, frailty, or other declines in physical or cognitive functioning . Many require some form of long term care, including home nursing, community care and assisted living. The costs associated with providing this support may need to be borne by families and society .
In less developed countries where established and affordable long-term care infrastructure is lacking or inadequate, this cost may have catastrophic effect on the family, that is, other family members withdrawing from employment or school to care for older relatives . In many developing countries, younger members of the family move to the cities and urban areas to seek jobs and the older relatives back home have less access to informal family care and support. The future need for long-term care services (both formal and informal) will largely be determined by changes in the absolute number of people in the oldest age groups coupled with trends in disability rates . Given the increases in life expectancy and the sheer numeric growth of older populations, demographic momentum will likely raise the demand for care. This growth could, however, be alleviated by declines in disability among older people. Further, the narrowing gap between female and male life expectancy reduces widowhood and could mean a higher potential supply of informal care by older spouses . The need to have longevity with quality is to keep older people healthy longer, delaying or avoiding disability and dependence.
According to the National Nursing Home Survey in 1999 in the United States, nearly 10 million people need long-term care [9-14], that is, need help with ADLs or IADLs. Most were aged 65 years and the risk of needing long-term rise steeply with age. Half of the older persons 85 years and older, needed some long-term care . Sex differences exist in the care needs of older persons, majority being women, among nursing home residents of all ages, 72 percent are women . Not surprisingly, the need for long-term care is often accompanied by other health-related needs. About two-thirds of adults living at home with long-term care needs are in fair or poor health. Furthermore, among community-dwelling older adults, those with long-term care needs had more health needs compared with community-dwelling older adults without long-term care needs .
In Ghana, there is paucity of research based information on the exact care needs of the aged population. The goal of this analysis is to provide timely research based knowledge of the socioeconomic differences in the prevalence of care need among older persons in Ghana which will be crucial in guiding the implementation of the 2010 National Aging Policy .
Material And Method
The data employed in this study were drawn from the World Health Organization Global Ageing and Adult Health (SAGE). This aims to evaluate the association of the care need and socio-demographic and socio-economic differences among older male and female Ghanaians [15-19]. It also aims at addressing the gap in reliable data and scientific knowledge on ageing and health in low – and middle –income countries. SAGE is a longitudinal study with nationally representative samples of persons aged 50+ years in Ghana with a smaller sample of adults aged 18-49 years. Wave 1 was conducted during 2007-2008 and included a total of 4770 respondents aged 50+ and 803 aged 18-49. In this study, 2313 (51.9%) men and 2141 (48.1%) women were involved. Face-to face interview was conducted in Ghana (2007-2008). Multistage cluster sampling strategies were used to select households. Household-level analysis weights and person-level analysis weights were calculated for each country, which included sample selection and a post-stratification factor . Post stratification correction techniques used the most recent population estimates provided by the Ghana Statistical Service. The pooled Wave 1 national total for individual respondents included 4770 respondents aged 50+ and 803 aged 18–49. A standardized survey instrument, set of methods, interviewer training and translation protocols are used in all SAGE countries .
Measures of care needed
Information of care needed was elicited in one question. The respondents were asked if they needed care due to their health conditions or because they are getting old and weak.
Socio-demographic and socio-economic measures
Predisposing measures were age (age 18-49 (young adults), 50-59 (adults) and 60yrs and above (older adults)), gender and marital status (currently married, never married, cohabitating, separated/divorced and widowed).
Enabling measures were assessed in terms of education, job employment, well-being and income. Education was recorded as college/university completed, high school completed, secondary school completed, primary school completed, less than primary school completed and no formal education.
Job employment was categorized into four groups: public, private, self-employed and informal employment. Public sector includes employees of state, or municipal governments and their agencies, and parastatal enterprises. Private sector includes any employees not working for the government and not self-employed [21-23]. Selfemployed includes those who earn their livelihood directly from their own trade or business rather than as an employee of another. Informal economy refers to the general market income category and income generations are unregulated by the institutions of society. Jobs in the informal economy are characteristically without benefits such as health insurance, sick leave, paid vacations or pensions.
Well-being status was recorded as completely, mostly, moderately, a little and not at all. Wealth or income Quintiles, Q1 (lowest) through Q5 (highest) were derived from the household ownership of durable goods, dwelling characteristics (type of floors, wells and cooking stove), and access to services (improved water, sanitation and cooking fuel) for a total of 21 assets. A two-step random effects probit model was used to generate the Quintiles .
Age-adjusted prevalence rates on all respondents were first computed for descriptive purposes. Analyses of care need with sociodemographic and socio-economic factors were carried out distinctively for men, women and both sexes by means of binary logistic regression analysis. Odds ratios (OR) and their respective 95% confidence intervals were also computed. Firstly, all variables in the analysis were unadjusted for each other. Secondly, each variable was adjusted for age (age-adjusted model). Those whose ages are less than 50 years, married, have no formal education, in the public sector and have the lowest income were used as the comparison group for all individual data outcomes . To examine how the observed associations of socio-demographic and socio-economic indicators with care need may change when several of these indicators are considered simultaneously, age-unadjusted and age-adjusted odds ratios from logistic regression analyses were compared. Stata SE (version 12.1) was used for analysis.
Fitted Logistic Regression Model
Given a logistic regression model,
We observed the outcome of the independent binomial trials with probability π ( x i) . Let y i be the observed responses. Then, the total likelihood is
and so the log-likelihood is
For some unknown vector of β where
Using the maximum likelihood to fit the model yields a set of equations to solve from considering
By using the assumed linear relation between the log odds and the predictors, this means that the MLE satisfies
Since MLEs are invariant under transformation hence if xi has a component of j that is always 1, for every i then, hence the empirical proportion of the positive response matches the average of the fitted probabilities.
The logistic model for π (xi) is the probability of the care need for a given value of the predictors,
where xi are the predictors
The odds of the disease (care need) when x=0 is .
The odds of the disease (care need) when x=1 is
The Odds Ratio (OR) of the condition (care need) =
This implies that
Prevalence of care need by socio-demographic variables
In our preliminary results, 85.4 % (persons 50+ years) and 14.6% (persons 18-49 years) reported they needed care. The prevalence of care need was 15.3% among young male adults (18-49 years), 35.5% among male adults (50-59 years) and 49.2% among older male adults (≥ 60 years) respectively (Table 1) A similar pattern of care need increasing with age was observed among females, young adult females (14.4%), adult females (30.5%) and older adult females (55.1%) respectively. Men who are currently married needed care more often than other men whereas women who are widowed needed care more often than other women (Table 2).
|Age Category||Male||Female||Both Sexes|
|Care need %||Care need %||Care need %|
|18 - 49||15.3||14.4||14.9|
|50 - 59||35.5||30.5||33.1|

Prevalence of care need by socio-economic variables
An educational gradient was found for care need: but in high school completed, the lower the education, the higher the prevalence of care need for both men and women. However, the self-employed had the highest percentage in terms of care need for both men and women in the employment category (Table 2).Care need varied by income status. Ghanaians who have moderate, little and no money showed high rates of care need as compared to those who have enough money [25-27]. Sex difference in socioeconomic status and care need existed; was wider among women compared to men.
|Care need||Care need||Care need|
|HIGHEST EDUCATIONAL LEVEL|
|no formal education||37.6||59.2||48.0|
|less than primary school||10.7||13.4||12.0|
|primary school completed||14.6||10.1||12.5|
|secondary school (O&A levels) completed||8.6||3.4||6.1|
|high school (or equivalent) completed||23.6||11.9||17.9|

Associations between different care outcomes and sociodemographic and socio-economic variables among men
Among men, care need was statistically significantly associated with both education and job employment in the age-unadjusted models, and tended to be lower in non-public sector and those who do not have just enough money to meet their needs (Table 3). In the age-adjusted model, the indicators remained statistically significantly associated with care need and tended to be lower in the adult and older adult groups, non-public sector and those who do not have just enough money to meet their needs (Table 3). Those having less than primary education, completed primary and senior secondary schools were clearly strongly more likely to receive care than those with no formal education in the age-unadjusted models. After adjusting for age, the situation remained unchanged except secondary school completed . Self-employed and informal employees were however less likely to receive care than public employees. It remained same even after adjusting for age. Nevertheless, both income and marital status showed weak and inconsistent association with care need in both ageunadjusted and age-adjusted models. In both age-unadjusted and ageadjusted models, statistically, care need was weakly associated with well-being, marital status and income.

Associations between different care outcomes and sociodemographic and socio-economic variables among women
Among women, care need was inconsistently associated with all studied variables except job employment in both age-adjusted and age unadjusted models (Table 3). This association remained unchanged after readjusting for all studied variables. However, care need among women was associated with older adults. In contrast to men, care need among women was also associated with higher educational level as college/university graduates were less likely to receive care than those women who have no formal education. Among women, care need showed association with relatively middle income quintile (Q3). In contrast to men, there was the statistically significant association with women . The third quintile (Q3) was more likely to receive care need than first quintile (Q1). After age was adjusted for all studied variables, the situation remained unchanged. Among both sexes, care need was significantly associated with all studied variables except income for both age-unadjusted and age-adjusted models.
Our analysis confirmed that care need is a phenomenon among ageing Ghanaians. The study revealed that 85.4% (persons 50+ years) and 14.6% (persons 18-49 years) of the survey population reported they needed care. According to literature, older individuals are living for much longer, with a significant burden of chronic disease, disability and impairments in cognition, sight, hearing and mobility (6).
According to (9), nearly 10 million people need long-term care in the United States (9); that is, need help with ADLs or IADLs. Most of these are aged 65 years and the risk of needing long-term rise steeply with age. Half of the older persons 85 years and older, needed some long-term care (9). In this analysis, the prevalence of care need was 15% among young male adults, 36% among male adults and 49% among older male adults respectively Care need also increased with age among females, young adult females (14%), adult females (31%) and older adult females (55%) respectively. Clearly, this goes to buttress the point that older persons require more supportive care and that care for older persons in Ghana should be one of the pillars for implementing the 2010 National Aging Policy.
This analysis revealed that women were mostly affected by socioeconomic difference in care need and that care need was highest for the older women (60 years or more), compared to the adult and younger adult females. This agrees with findings from some previous studies which indicated that more women need long-term care (9) and also among community residents (aged 18 to 64, and those aged 65 and older) who require long term care are women. In addition nursing home residents of all ages, 72 percent are women (10).
Among both men and women, those with lower education had a high prevalence of care need and the self-employed persons had the highest care need. . Also, older persons with moderate, little or no money showed high rates of care need compared to those who had enough money. Kinsella and He in a study in 2009 indicated that in developed countries with limited established and affordable long-term care infrastructure, the cost of care need for older persons was in the form of other family members withdrawing from employment or school to care for their older relatives . In contrast, in developing countries, residents looked for jobs in the cities or other urban areas while their older relatives back home had less access to informal family care.
Among older persons in this national survey, the self-employed and informal employees were less likely to receive care than public employees. Probably, access to pension by public sector employees may improve access to care need. As demonstrated in the analysis, care need for women was consistently associated with job employment.
However, among both sexes, income levels of older persons in Ghana showed weak and inconsistent association with care need in both ageunadjusted and age-adjusted models.
In contrast to men, care needs among women was associated with higher educational level such that college/university graduates were less likely to require care than those who had no formal education. Older adult females (60 years and above) need care more than adult females (50-59 years) and young adult females (18-49 years) respectively. Interestingly, men who are currently married need care more than other men whilst women who are widowed need care more than other women. Remarriage is increasingly prevalent, especially among men, with older widowed or divorced men more likely to remarry later in life than comparable older women. Thus marriage is normative for older men, and most men are married when they die (12).
While this study examined care need by socio-demographic and socioeconomic indicators amongst males and females, an alternative approach is to examine the implication of ageing and care needs, compressed morbidity and how long care need should be provided. It is evident that older people live much longer with significant burden of chronic disease disability and impairment and lose their ability to live independently (5).
Limitation: The SAGE Wave I in Ghana relied mostly on selfreported information and as care need is an objective experience, this may be a limitation of the study. Factors such as physical function, cognitive function, and co-morbidities which are important confounders to care were not included in the analysis. However, the responses to care questions provide reliable information for more in depth examination of care need among older persons in Ghana.
Care need was more prevalent among older female adults and showed predisposing and enabling factor disparities. The analysis revealed that women were mostly affected by socioeconomic difference in care need. Care need increased with age for both men and women. Those with lower education and the self-employed had a high prevalence of care need for both men and women. Also, older persons with moderate, little or no money for daily living showed high rates of care need compared to those who had enough money. It is hoped that the gender disparities and other differences in care need among older persons identified in this analysis will guide the implementation of the 2010 National Aging Policy in Ghana. Importantly, SAGE can be used to further document impact and also as a monitoring mechanism for the 2010 National Aging Policy with SAGE Ghana Wave 2 planned for 2013/14.
