Exploring the association of self-rated oral health with self-rated general and mental health among older adults in a resource-poor context: Insights for advancing Sustainable Development Goal 3.

INTRODUCTION: Older adults in Ghana have been disproportionately affected by oral health issues such as caries and periodontitis. This situation calls for comprehensive attention within health and healthcare policies, due to the established connections between oral health and other aspects of health and well-being in high-income countries, including physical and mental health. However, there is a significant gap in the literature when it comes to exploring the association of oral health with physical and mental health in resource-constrained settings like Ghana. METHODS: To address this void, we collected a cross-sectional sample comprising older adults aged 60 and above (n = 1073) and analyzed self-rated health measures to investigate the relationship between oral health and general and mental health in Ghana. RESULTS: The results of our logistic regression analysis revealed a significant association: older adults who reported poor oral health were more likely to rate their general (OR = 5.10; p < .001) and mental health (OR = 4.78, p < .001) as poor, compared to those with good oral health, even after accounting for demographic and socioeconomic variables. CONCLUSIONS: Based on these findings, we discuss the policy implications of our findings, especially in the context of advancing Sustainable Development Goal 3 in Ghana and other resource-constrained settings.

Factors Associated with the Uptake of HIV Testing in Canada: Evidence from a Nationally Representative Study.

In this study, we explore the factors associated with the uptake of HIV testing at the national level in Canada. Using the 2015-16 Canadian Community Health Survey and applying logistic regression analysis, we examine the associations between HIV testing and factors identified by the Andersen's behavioral model of healthcare utilization. We find that a range of predisposing, enabling, and need factors are significantly associated with HIV testing. For example, compared to the oldest respondents (i.e. 55-64), their younger counterparts (i.e. 45-54, 35-44, and 25-34) are more likely to have been tested for HIV. Compared to those in Atlantic Canada, respondents in Quebec (OR = 1.96, p < .001), Ontario (OR = 1.44, p < .001), Prairies (OR = 1.37, p < .001), British Columbia (OR = 1.99, p < .001), and the Territories (OR = 2.22, p < .001) are all more likely to have been tested for HIV. Based on these findings, we provide several important suggestions for policymakers and future research.

Family Support, Perceived Physical Activeness and Chronic Non-Communicable Diseases as Determinants of Formal Healthcare Utilization Among Older Adults with Low Income and Health Insurance Subscription in Ghana.

Evidence suggests that enrollment in a health insurance scheme is associated with higher levels of formal healthcare utilization among older adults, especially those with low income in sub-Saharan Africa (SSA), including Ghana. This study examines the prevalence of formal healthcare utilization and associated factors among older adults with low income and health insurance subscription enrolled in a social intervention program (known as the Livelihood Empowerment Against Poverty [LEAP] program) in Ghana. Cross-sectional data were obtained from an Aging, Health, Lifestyle and Health Services Survey conducted in 2018 among 200 older adults aged 65 years and above enrolled in the LEAP program. The results showed that almost 9 in 10 (87%) older adults utilized formal healthcare services for their health problems. Older adults who received family support, rated themselves to be physically active and had non-communicable diseases (NCDs) were more significantly likely to utilise formal health care services than their counter parts. We recommend that health policies and programs for older adults with low income and health insurance subscription under the LEAP program should consider the roles of family support, physical activeness and NCDs in influencing their use of formal healthcare services.

Microarray Gene Expression Data Classification via Wilcoxon Sign Rank Sum and Novel Grey Wolf Optimized Ensemble Learning Models.

Cancer is a deadly disease that affects the lives of people all over the world. Finding a few genes relevant to a single cancer disease can lead to effective treatments. The difficulty with microarray datasets is their high dimensionality; they have a large number of features in comparison to the small number of samples in these datasets. Additionally, microarray data typically exhibit significant asymmetry in dimensionality as well as high levels of redundancy and noise. It is widely held that the majority of genes lack informative value about the classes under study. Recent research has attempted to reduce this high dimensionality by employing various feature selection techniques. This paper presents new ensemble feature selection techniques via the Wilcoxon Sign Rank Sum test (WCSRS) and the Fisher's test (F-test). In the first phase of the experiment, data preprocessing was performed; subsequently, feature selection was performed via the WCSRS and F-test in such a way that the (probability values) p-values of the WCRSR and F-test were adopted for cancerous gene identification. The extracted gene set was used to classify cancer patients using ensemble learning models (ELM), random forest (RF), extreme gradient boosting (Xgboost), cat boost, and Adaboost. To boost the performance of the ELM, we optimized the parameters of all the ELMs using the Grey Wolf optimizer (GWO). The experimental analysis was performed on colon cancer, which included 2000 genes from 62 patients (40 malignant and 22 benign). Using a WCSRS test for feature selection, the optimized Xgboost demonstrated 100% accuracy. The optimized cat boost, on the other hand, demonstrated 100% accuracy using the F-test for feature selection. This represents a 15% improvement over previously reported values in the literature.

Determinants of COVID-19 knowledge and self-action among African women: Evidence from Burkina Faso, the Democratic Republic of Congo, Kenya, and Nigeria.

Knowledge of infectious diseases and self-action are vital to disease control and prevention. Yet, little is known about the factors associated with knowledge of and self-action to prevent the coronavirus disease (COVID-19). This study accomplishes two objectives. Firstly, we examine the determinants of COVID-19 knowledge and preventive knowledge among women in four sub-Saharan African countries (Kenya, Nigeria, the Democratic Republic of Congo, and Burkina Faso). Secondly, we explore the factors associated with self-action to prevent COVID-19 infections among these women. Data for the study are from the Performance for Monitoring Action COVID-19 Survey, conducted in June and July 2020 among women aged 15-49. Data were analysed using linear regression technique. The study found high COVID-19 knowledge, preventive knowledge, and self-action among women in these four countries. Additionally, we found that age, marital status, education, location, level of COVID-19 information, knowledge of COVID-19 call centre, receipt of COVID-19 information from authorities, trust in authorities, and trust in social media influence COVID-19 knowledge, preventive knowledge, and self-action. We discuss the policy implications of our findings.

Healthcare seeking behaviour during illness among older adults in Ghana: does food security status matter?

BACKGROUND: Ghana's growing older adult population raises critical questions regarding healthcare for these older adults. At the same time, food insecurity is high among older adults in Ghana. This underscores the need to investigate the issues of food security and healthcare seeking behaviour among older adults. However, research on the association between food security status and healthcare seeking behaviour among older adults is scant in the Ghanaian context. In this study, we advance the social gerontology literature by examining the association between food security status and healthcare seeking behaviors among older adults. METHODS: Using a multi-stage sampling framework, we collected data from a representative sample of older adults across three regions in Ghana. Data were analyzed using logistic regression technique. We determined the significance of the test at a probability value of 0.05 or less. RESULTS: Over two-thirds (69%) of respondents did not seek care during their last illness. Additionally, 36% of respondents were severely food insecure, 21% were moderately food insecure, 7% were mildly food insecure, and 36% were food secure. After controlling for theoretically relevant variables, our multivariable analysis revealed a statistically significant association between food security status and healthcare seeking behaviors with older people who are food secure (OR = 1.80, p < 0.01) and mildly food insecure (OR = 1.89, p < 0.05) being more likely to seek healthcare compared with their counterparts who are food insecure. CONCLUSION: Our findings highlight the need for sustainable intervention programs to improve food access and health service use among older adults in Ghana and similar contexts.

Understanding the association between unmet dental care needs and household food security status among older people in Ghana.

The literature recognizes food insecurity as a barrier to access to health care services. However, we know very little about the association between food insecurity and unmet dental care needs among older people in Ghana. To address this void in the literature, this study uses a representative survey of adults aged 60 or older from three regions in Ghana to examine whether older people who experienced household food insecurity differently report unmet dental care needs in comparison to their counterparts without any food insecurity. We find that 40% of older adults reported unmet dental care needs. Results from logistic regression analysis show that older people who experienced severe household food insecurity were more likely to report unmet dental care needs, compared to those who did not experience any type of food insecurity, even after accounting for theoretically relevant variables (OR = 1.94, p < 0.05). Based on these findings, we discuss several implications for policymakers and directions for future research.

Understanding the Link between Household Food Insecurity and Self-Rated Oral Health in Ghana.

There is increasing scholarly attention on the role of food insecurity on the health of older adults in sub-Saharan Africa, including Ghana. Yet, we know very little about the association between food insecurity and self-rated oral health. To address this void in the literature, this study uses a representative survey of adults aged 60 or older from three regions in Ghana to examine whether respondents who experienced household food insecurity rated their oral health as poor compared to their counterparts who did not. We found that 34% of respondents rated their oral health as poor, while 7%, 21%, and 36% experienced mild, moderate, and severe food insecurity, respectively. Moreover, the results from the logistic regression analysis showed that older adults who experienced mild (OR = 1.66, p < 0.05), moderate (OR = 2.06, p < 0.01), and severe (OR = 2.71, p < 0.01) food insecurity were more likely to self-rate their oral health as poor, compared to those who did not experience any type of food insecurity. Based on these findings, we discuss several implications for policymakers and directions for future research.

"They Do Not Care about Us Anymore": Understanding the Situation of Older People in Ghana.

While existing research acknowledges copious challenges faced by older adults (people aged 60 and over) in Ghana and most countries in sub-Saharan Africa, they fail to situate the lived experiences of this vulnerable group within the broader context of health geography and public health. This paper draws insights from ecological systems theory and the "geographies of older people" literature to examine the lived experiences of older people in Ghana. Data for the study were gathered using interviews (42) and sharing circles (10). Our findings reveal a complex mix of experiences consistent with the different levels of the environment. Dominant themes include access to social support, functional impairment and poor health status, social status, poor access to water and sanitation services, food insecurity, economic insecurity, and caregiving burden. These findings support the wide-held notion that the experiences of older people are complex and produced by the interplay of both individual and structural factors. Our findings demonstrate that sociocultural, economic, political, and climatic factors are important consideration in promoting elderly wellbeing and quality of life in Ghana.

Effect of cognitive and structural social capital on depression among older adults in Ghana: A multilevel cross-sectional analysis.

Evidence from existing studies suggests social capital has mixed effects on depression and other common mental disorders. There is little knowledge of the possible association between social capital and depression among the growing older population in sub-Saharan Africa. This study investigates the effect of cognitive social capital (trust and sense of safety) and structural social capital (social participation or engagement in social activities) on depression among older adults in Ghana. Utilizing multilevel mixed-effect analysis, we investigate the effect of individual-level and neighborhood-level social capital (cognitive and structural) on depression using data from the World Health Organization Study on Global Ageing and Adult Health (WHO-SAGE) survey (Wave 1). The findings show that at an individual level, older adults who felt safe at home were less likely to have depression. We observed mixed results for elements of structural social capital at the individual level. Older adults who frequently engaged in club or group meetings, worked with neighbors and engaged in social outings were more likely to have depression; while attending public meetings and socializing with co-workers were associated with reduced likelihood of having depression. At the neighborhood level, increased trust in neighbors was associated with an increased likelihood of having depression (OR = 1.01, p < 0.05) while higher levels of neighborhood safety and structural social capital were associated with a reduced likelihood of having depression. The findings suggest that the differential associations between elements of social capital and depression may be the result of contextual factors.

Modern or traditional health care? Understanding the role of insurance in health-seeking behaviours among older Ghanaians.

AIM: This paper examined the association between wealth and health insurance status and the use of traditional medicine (TM) among older persons in Ghana. BACKGROUND: There have been considerable efforts by sub-Saharan African countries to improve access to primary health care services, partly through the implementation of risk-pooling community or national health insurance schemes. The use of TM, which is often not covered under these insurance schemes, remains common in many countries, including Ghana. Understanding how health insurance and wealth influence the use of TM, or otherwise, is essential to the development of equitable health care policies. METHODS: The study used data from the first wave of the World Health Organisation's Study of Global Ageing and Adult Health conducted in Ghana in 2008. Descriptive statistics and negative loglog regression models were fitted to the data to examine the influence of insurance and wealth status on the use of TM, controlling for theoretically relevant factors. FINDINGS: Seniors who had health insurance coverage were also 17% less likely to frequently seek treatment from a TM healer relative to the uninsured. For older persons in the poorest income quintile, the odds of frequently seeking treatment from TM increased by 61% when compared to those in the richest quintile. This figure was 46%, 62% and 40% for older persons in poorer, middle and richer income quintiles, respectively, compared to their counterparts in the richest income quintile. CONCLUSION: The findings indicate that TM was primarily used by the poor and persons who were not enrolled in the National Health Insurance Scheme. TM continues to be a vital health care resource for the poor and uninsured older adults in Ghana.

Access to primary health care among women: the role of Ghana's community-based health planning and services policy.

BACKGROUND: Ghana in 1999 adopted the Community-based Health Planning and Service (CHPS) policy to enhance access to primary health care (PHC) service. After two decades of implementation, there remains a considerable proportion of the country's population, especially women who lack access to basic health care services. AIM: The aim of this paper is to understand the contribution of Ghana's CHPS policy to women's access to PHC services in the Upper West Region (UWR) of Ghana. METHODS: A logistic regression technique was employed to analyse cross-sectional data collected among women (805) from the UWR. FINDINGS: We found that women who resided in CHPS zones (OR = 1.612; P ≤ 0.01) were more likely to have access to health care compared with their counterparts who resided in non-CHPS zones. Also, rural-urban residence, distance to health facility, household wealth status and marital status predicted access to health care among women in the region. Our findings underscore the need to expand the CHPS policy to cover many areas in the country, especially rural communities and other deprived localities in urban settings.

Married women's autonomy and post-delivery modern contraceptive use in the Democratic Republic of Congo.

BACKGROUND: Although use of modern contraception is considered beneficial in lowering maternal and child mortality rates, the prevalence of contraceptive use remains low in the Democratic Republic of Congo. This study examined modern contraceptive use and its linkage to women's autonomy. METHODS: Data were drawn from the 2013-2014 Democratic Republic of Congo Demographic and Health Survey. We selected unsterilized and non-pregnant married women who have given birth in the last three years (N = 6680). Logistic regression models were fitted to explore the relationship between women's autonomy and modern contraceptive use. RESULTS: The study found that only 7.1% of married women who had delivered within three years used modern contraceptive methods. After controlling for socioeconomic and demographic factors, the association between women's autonomy and modern contraceptive use remained positively significant (OR = 1.16; 95% CI = 1.05, 1.29). CONCLUSION: The findings from this study indicate that it is not enough to provide women with educational and employment opportunities to increase the uptake of modern contraception, but also to enhance women's assertiveness to make their own decisions regardless of their partners' preferences within household settings. It is critical for government and other stakeholders to roll out programs aimed at reducing gender inequality and improving women's autonomy in decision-making about reproductive health.

Examining the association between exposure to mass media and health insurance enrolment in Ghana.

Although previous studies have explored the National Health Insurance Scheme (NHIS) in Ghana, very little attention is paid to the influence of mass media exposure on NHIS enrolment. Yet, understanding this linkage is important, particularly due to the critical role of mass media in disseminating health information and shaping people's health perceptions and choices. Using data from the 2014 Ghana Demographic and Health Survey, we employed logistic regression analysis to understand the relationship between NHIS enrolment and exposure to print media, radio, and television. Our findings indicate that women with more exposure to radio (OR = 1.23, P < 0.01) and television (OR = 1.24, P < 0.01) were more likely to enroll in the NHIS than those with no exposure. For men, more exposure to print media was associated with higher odds of enrolling in the NHIS (OR = 1.41, P < 0.01). In conclusion, all 3 types of media may be helpful in promoting NHIS enrolment in Ghana. However, given that the relationship between media exposure and enrolment in the NHIS was gendered, we recommend that policymakers should pay attention to these dynamics to ensure effective targeting in NHIS media campaigns for increased enrolment into the scheme.

Debated agronomy: public discourse and the future of biotechnology policy in Ghana.

This paper examines the highly contested and ongoing biotechnology (Bt) policy-making process in Ghana. We analyse media content on how Bt is viewed in the context of Ghana's parliamentary debate on the Plant Breeders Bill and within the broader public policy-making literature. This paper does not seek to take a position on Bt or the Bill, but to understand how policy actors influence the debate with political and scientific rhetoric in Ghana. The study reveals that in the midst of scientific uncertainties of Bt's potential for sustainable agriculture production and food security, policy decisions that encourage its future adoption are heavily influenced by health, scientific, economic, environmental and political factors dictated by different ideologies, values and norms. While locally pioneered plant breeding is visible and common in the Ghanaian food chain, plant breeding/GMOs/Bt from international corporations is strongly resisted by anti-GMO coalitions. Understanding the complex and messy nature of Bt policy-making is critical for future development of agricultural technology in Ghana and elsewhere.
