Abstract
Background:
Although approximately 79% of the world’s suicides occur in low- and middle-income countries (LMICs), the limited research in these regions has primarily focused on the rates of suicide attempts (SA) and ideation among men and younger members of the population.
Aim:
This study investigated the associations between bodily pain, functional limitation, chronic health conditions, and suicidal ideation among older Ghanaian women with a positive screen for depression.
Methods:
Data was obtained from the World Health Organization’s Study on global AGEing and adult health (SAGE) Ghana Wave 1, a nationally representative sample. Based on the interpersonal theory of suicide, we used logistic regression analysis to investigate the associations between the variables.
Results:
Functional limitation, bodily pain, hopelessness, and hypertension were significantly associated with a higher risk of suicidal ideation after accounting for sociodemographic and other confounding factors.
Conclusions:
Early interventions designed to decrease hopelessness, hypertension, and functional limitations may lead to reduced suicide ideation among older Ghanaian women who screen positive for depression.
Suicide is a global public health problem responsible for more than 800,000 deaths annually (World Health Organization [WHO], 2019) and is considered a complex phenomenon resulting from the interaction of individual, social, and environmental factors (WHO, 2014). The reduction of suicide mortality has been prioritized by the World Health Organization (WHO) as a global target and included as an indicator in the United Nations Sustainable Development Goals (SDGs) under target 3.4 (WHO, 2020). Notably, older adults (⩾70 years) have the highest suicide rates in nearly every region of the world (WHO, 2014). To date, existing research has been predominantly conducted within Western societies (Adinkrah, 2020), despite evidence suggesting that low- and middle-income countries (LMICs) account for 79% of suicides worldwide and will hold an estimated 80% of the older adult population by 2050 (WHO, 2018, 2019).
The scarcity of suicide research in the SSA region, including Ghana, may partly be a consequence of the illegality of suicidal behavior in many areas of Africa (Adinkrah, 2020). Current law in Ghana designates attempted suicide as a crime punishable by legal penalties such as monetary fines or incarceration (Hjelmeland et al., 2014). Suicide illegality poses challenges for researchers as there are no formal reporting systems for suicide statistics (e.g. National Violent Death Reporting System in the United States; Osafo et al., 2020). Previous studies investigating suicidality in Ghana have used non-representative approaches to data collection, such as media content analysis (Quarshie et al., 2021) and qualitative interviews (Akotia et al., 2019), which provide important insights but are limited to suicidal behaviors of the target populations of these studies. The issue of suicide illegality is compounded by a cultural climate that rejects and excludes suicide attempters (Adinkrah, 2020), ultimately rendering the discussion of suicidal ideation a taboo topic and discouraging suicide research. Thus, the aim of the present study is to address this limitation in the research on suicidality in SSA by examining the relationship between bodily pain, functional limitation, and chronic health conditions.
A prominent framework that may be relevant to understanding the phenomenon of suicidal behaviors among older adults in Ghana is the interpersonal theory of suicide (IPTS; Joiner, 2005). IPTS posits that suicide is preceded by three conditions: thwarted belongingness (a perceived absence of positive and caring connections to others that causes a painful sense of not belonging), perceived burdensomeness (a self-perception that one’s death is worth more than their life to others), and an acquired capability for suicide (Joiner, 2005). Specifically, thwarted belongingness and perceived burdensomeness initiate and maintain suicidal desire, while an acquired capability for suicide produces the necessary conditions for a suicide attempt or death (Joiner, 2005; Van Orden & Conwell, 2011). Applied to older adults, IPTS has been expanded to include five key risk factors: psychiatric illness, social isolation, functional impairment, physical illness and pain, and access to lethal means (Van Orden & Conwell, 2011). Although the data collected in this study does not allow for a comprehensive test of this framework, the IPTS for late life provides a conceptual guide for understanding and interpreting the associations between physical health and suicidal ideation among older women in SSA.
In the last decade, a growing body of work has documented the connection between physical health, pain, and suicidality in older adults (Conejero et al., 2018; Fässberg et al., 2016; Racine, 2018). A systematic review (Fässberg et al., 2016) examining the relationships between physical illness, functional disability, and suicidality among older women and men (⩾65 years of age) revealed connections between physical illness, functional disability, and suicidal ideation. Specifically, poor subjective health, functional disability, and pain were independently and significantly associated with suicidal ideation. Similarly, a review by Santos et al. (2020) identified an increased risk for suicidal behavior among older men and women (⩾60 years and over) who reported higher levels of bodily pain. This review suggested that the inability to control physical suffering and the threat of losing one’s sense of independence and value may result in feelings of hopelessness, leading to a higher risk of suicidality. While such results underscore physical and mental health as crucial correlates of suicidal behaviors in older adults, these relationships have yet to be evaluated in many non-Western contexts such as Ghana.
To our knowledge, only two studies have explored the association between suicide and physical health within SSA. Adewuya et al. (2016) examined the prevalence and correlates of suicidal ideation in a representative sample of adult Nigerian men and women aged 18 to 74 years (M = 36.75, SD = 12.3), and included a brief assessment of physical disability severity. Logistic regression analyses revealed a significant positive association between moderate and severe physical disability and suicidal ideation. Similarly, Acheampong and Aziato (2018) interviewed 12 Ghanaian mothers with physical disabilities who had given birth within the last 10 years regarding their experiences with suicidal ideation, exposing a high prevalence of suicidal ideation within this population. In tandem, these studies demonstrate the limited knowledge available and the need for further investigation on the association of physical ailments on suicidal ideation within SSA.
The dearth of research on suicidal behaviors and older women’s health issues in SSA merits an in-depth, quantitative examination of the effects of chronic illnesses, bodily pain, and functional limitations on suicidal ideation using representative data. Based on the IPTS framework adapted for late life (Van Orden & Conwell, 2011), the present study uses nationally representative data from Ghana to investigate whether chronic health conditions, bodily pain, and functional limitation have significant associations with suicidal ideation among older women. We hypothesized that bodily pain, functional limitation, and the presence of chronic health conditions would be significantly positively associated with a higher risk of suicidal ideation. We tested this hypothesis while accounting for other known predictors
Method
Procedure and participants
The present study was conducted using Wave 1 (collected between 2007 and 2010) of the World Health Organization’s Study on global AGEing and adult health (SAGE-Ghana; Kowal et al., 2012). SAGE is a longitudinal study of aging, health, and well-being among adults in Ghana, China, India, Mexico, Russia, and South Africa. Wave 1 was nationally representative and targeted men and women 50 years and older, with a smaller sample of individuals between the ages of 18 and 49 for comparison purposes. In all six SAGE countries, a stratified multistage cluster sampling method was used to collect data from nationally representative cohorts (Naidoo, 2012). A total of 5,573 individuals 18 years and older were surveyed for SAGE-Ghana Wave 1. Of the eligible individuals, 849 participants were excluded because they were younger than 50 years old at the time of the study, identified as men (n = 2,379), or did not respond to the suicidal ideation question (n = 2,094). To respond to the suicidal ideation question, participants had to answer ‘yes’ to a set of questions that screened for depression. A final analytic sample of 251 women was used in this study.
Measures
Suicidal ideation
A question based on the World Mental Health Survey version of the Composite International Diagnostic Interview (CIDI) was used to ask participants to indicate if they experienced suicidal ideation in the last 12 months: ‘During the last 12 months, did you think of death, or wish you were dead?’ Response options were ‘Yes’ or ‘No’. Participants who responded ‘Yes’ were considered as having experienced suicidal thoughts.
Self-rated health
Participants were asked to rate their subjective overall general health using a single question: ‘In general, how would you rate your health today?’ on a 5-point Likert scale from 1 (very good) to 5 (very bad). Scores were reverse coded so that higher scores indicated better health.
Bodily pain
Participants were asked to rate their perceptions of bodily pain in the past 30 days with the following question, ‘Overall in the past 30 days, how much bodily pain did you have?’ Response options were on a 5-point Likert scale ranging from 1 (none) to 5 (extreme/cannot do). For the present study, responses were recoded into three groups based on low, moderate, and high pain levels: 1 (none and mild pains), 2 (moderate), and 3 (severe and extreme/cannot do).
Chronic health conditions
Participants were asked to self-report any chronic health conditions diagnosed in the last 12 months (i.e. hypertension [high blood pressure], asthma, chronic lung disease, diabetes [high blood sugar], stroke, heart disease, and arthritis) with the following item: ‘Have you ever been diagnosed with/told by a health care professional you have (health condition)?’ Response options were ‘Yes’ or ‘No’. To identify specific conditions related to suicidal ideation, each chronic health diagnosis was entered as a separate variable in the analyses.
Functional limitation
Functional limitation was assessed using three separate items. Participants were asked to rate their perceived level of difficulty in performing work or household activities, vigorous activities, and self-care in the past 30 days. Responses options were rated on a 5-point Likert scale from 1 (none) to 5 (extreme/cannot do). We recoded the household limitations into three groups: 1 (none and mild), 2 (moderate), and 3 (severe and extreme/cannot do). The responses to self-care limitations were recoded into two groups: 1 (none, mild, moderate, and severe) and 2 (extreme/cannot do).
Hopelessness
Participants were asked to indicate if they felt hopeless in the last 12 months with a single item, ‘Did you frequently feel hopeless – that there was no way to improve things?’ Response options were ‘Yes’ or ‘No’.
Social connectedness
This variable was measured using three items: participation in religious activities, hosting friends, and leaving the house. Participants were asked to indicate the frequency of their participation in the last 12 months. Responses were: 1 (never), 2 (1-2x per year), 3 (1-2x per month), 4 (1-2x per week), and 5 (daily). The 4 and 5 response categories were grouped together to indicate ‘high social connectedness’, while the rest indicated ‘low social connectedness’.
Depressed affect
Depressed affect was measured using the item, ‘During the last 12 months, have you had a period lasting several days when you felt sad, empty or depressed?’ Response options were ‘Yes’ or ‘No’.
Sociodemographic variables
The following sociodemographic information was included in the analyses: age, years of education, geographic location, and marital status. Age and education were self-report, continuous variables. Respondents also reported whether their region of residence was rural or urban.
Ethical considerations
SAGE was approved by the World Health Organization’s Ethical Review Committee. In addition, ethical approval was granted from the University of Ghana College of Health Sciences Research Ethics Committee. Written informed consent was obtained from all participants.
Data analytic plan
All statistical analyses were performed in IBM SPSS Statistics software Version 23.0 for Macintosh, and statistical significance was set at p < .05 for all analyses. Prior to the primary analyses, the main study variables were examined for missingness and violations of multivariate assumptions. A missing values analysis showed that 7% of the data were missing. Little’s (1988) Missing Completely at Random (MCAR) test was not significant, X2 = 2542.77, DF = 2,451, p = .60, indicating data was missing completely at random. Missing values were omitted using listwise deletion because it has little impact on the validity of statistical inferences in data sets where missing data is <10% (Bennett, 2001). Descriptive analyses of the sociodemographic characteristics of the sample were conducted first. To investigate associations between bodily pain, functional limitation, chronic health conditions, and suicidal ideation, binomial logistic regression was performed with suicidal ideation as the dichotomous outcome variable. Age, years of education, marital status, and geographic location were adjusted for in the analyses. Additionally, we adjusted for self-reported health, social connectedness, and hopelessness in the analyses due to prior research identifying these variables as risk factors for suicide and suicidal ideation among older adults (Brown et al., 2000; Conwell et al., 2011; Van Orden & Conwell, 2011).

Sample characteristics
Table 1 presents the characteristics of the sample of n = 251 women (ranging between 50 and 100 years; Mage = 66, SD = 11.2) with valid responses to the outcome variable, suicidal ideation. A little over 100 respondents (n = 109; 43%) reported suicidal thoughts in the last 12 months. More than half of the respondents (n = 133; 53%) lived in rural areas and the majority (n = 170; 68%) had no formal education. The majority of women were widows (n = 134; 53%), attended religious activities once or twice a week (n = 143; 57%), and stated feelings of hopelessness in the previous month (n = 185; 74%). A similar proportion of respondents indicated mild (n = 97; 39%) and moderate (n = 84; 34%) bodily pain and approximately half of the respondents (n = 122; 49%) reported moderate overall health. One hundred nine (n = 109; 43%) women indicated moderate difficulty when doing strenuous activities.

Main analyses
After adjusting for sociodemographic variables, hopelessness, depressed affect, and social connectedness, suicidal ideation was predicted by four different variables with model parameters of X2(29) = 83, p < .001, Nagelkerke R2 = 0.38. With respect to bodily pain, regression results (Table 2) showed that mild and moderate pains were associated with a lower risk of suicidal ideation among the older women (Odds ratio [OR] = .30; 95%CI [0.13, 1.02]; p < .05); (OR = 0.29; 95%CI = 0.11, 0.79; p < .01; respectively). With respect to functional limitation when conducting vigorous activities, women with no limitation (OR = 0.05; 95%CI [0.01, 0.38]; p < 001), mild limitation (OR = 0.10; 95%CI [0.02, 0.49]; p < .01), and severe limitation (OR = 0.36; 95%CI [0.13, 0.99]; p < .05) were significantly associated with lower risk of suicidal ideation when compared to their counterparts with extreme limitations. Additionally, hypertension was the only chronic health condition significantly associated with suicidal ideation. Women who had hypertension were 0.46 times less likely to have suicidal thoughts (OR = 0.46; 95%CI [0.21, 1.00]; p < .05). Finally, individuals who reported feeling hopeless were almost five times more likely to think about suicide (OR = 4.30; 95%CI [1.78, 10.37]; p < .001) than individuals who did not report feeling hopeless.

Discussion
The current study examined the relationship between bodily pain, functional limitation, chronic health conditions, and suicidal ideation in older Ghanaian women. Based on tenants of the interpersonal theory of suicide (Joiner, 2005), we hypothesized that greater bodily pain, more chronic health conditions, and higher functional limitation would be significantly associated with increased suicidal ideation. Overall, the results supported our hypothesis. Within a representative sample of 251 older women in Ghana, bodily pain, functional limitation, and hypertension were significantly associated with a higher likelihood of suicidal ideation, with hopelessness emerging as the most robust correlate of suicidal ideation. Generally, these results correspond with previous research indicating that physical pain, chronic health conditions, and functional limitation confer increased risk for suicidality, specifically within older adult populations (De Leo & Spathonis, 2003; Santos et al., 2020; Van Orden & Conwell, 2011).
Consistent with our hypothesis, the results of this study show that older women with mild (0.30 times) and moderate (0.29 times) bodily pain were less likely to think about pain when compared to individuals with severe bodily pain. Though previous studies from Ghana have not assessed severe or extreme bodily pain as a risk factor for suicidal ideation, these results are consistent with literature from other parts of the world indicating that individuals with higher degrees of bodily pain were more likely to contemplate suicide (Santos et al., 2020). One explanation for this association is that older women with extreme or severe bodily pain may feel powerless about their capacity to alleviate their discomfort and subsequently contemplate suicide as a solution to end the suffering caused by the pain (Sand et al., 2008; Santos et al., 2020). Additionally, in line with the IPTS adapted for late-life, habituation to pain may play a role in the acquired capability for suicide, acting as a potential catalyst for suicidal ideation to translate into suicidal behavior (Van Orden & Conwell, 2011). Furthermore, depression is highly comorbid with bodily pain and may play a mediating role between pain and suicidality (Racine, 2018; Santos et al., 2020). Thus, it is possible that increased bodily pain, perhaps in tandem with habituation and depression, may constitute a risk factor for a higher likelihood of suicidal ideation in older women in SSA. Although the current study was unable to measure suicidal behavior, the translation of suicidal ideation to suicidal behavior in older women in SSA would be an essential topic for future research.
Results from the present study revealed that older Ghanaian women with zero, mild, and severe limitations had lower risks for suicidal ideation than those with extreme limitations. Functional ability is particularly important for older individuals because it dictates independence and the onset of assisted care (Mor et al., 1994). These activities are often necessary for independent living, social interaction, and daily routine activities. Therefore, functional limitations may predict higher suicidal ideation among older women as women may perceive themselves as a burden to others as they lose personal autonomy and control (Van Orden & Conwell, 2011).
In this study, hypertension was the only significant predictor of suicidal ideation of the chronic health conditions examined.
While the present study focused on physical health indicators, we also accounted for known covariates of suicidal ideation among older people. Particularly, we accounted for feeling sad, depressed, and empty in addition to hopelessness. Results indicated that the risk for suicidal ideation was about five times higher among hopeless individuals than their more hopeful counterparts. This finding is in line with existing studies that have shown a higher risk of suicidal ideation associated with hopelessness (Brown et al., 2000; Szanto et al., 2002; Uncapher et al., 1998).
Limitations
This study has several limitations. First, the cross-sectional design of this study limits the ability to determine temporal or causal relationships between suicidal ideation and physical health factors.
Implications and future directions
Regarding implications for policy and practice, these findings highlight the importance of culturally responsive initiatives to address the intersection of physical health and suicidality. The heightened stigma around suicidality and policies that outlaw suicide in Ghana create a unique dynamic to engage the community in suicide prevention efforts. Policy reform to decriminalize suicide in Ghana is critical to long-term efforts of reducing suicide rates. However, initial efforts could include community and healthcare providers’ education regarding the associations between physical and mental health, with a specific focus on bodily pain, functional limitation, and hopelessness.
Conclusion
In summary, the present study demonstrated a significant positive association between self-reported hypertension, functional limitation, bodily pain, hopelessness, and suicidal ideation in older Ghanaian women with potential depression. Findings highlight the need for additional research to deepen our understanding of risk and protective factors for suicidal ideation in older women living in SSA. Importantly, this study contributes preliminary, quantitative evidence for further investigation into the connections between physical and mental health in Ghana and similar settings where suicidal behaviors among older women have received limited attention due to the taboo and illegal nature of the topic.
