Age and sex-specific disability-free life expectancy in urban and rural settings of Bangladesh.

BACKGROUND: Disability-free life expectancy (DFLE) has been used to gain a better understanding of the population's quality of life. OBJECTIVES: The authors aimed to estimate age and sex-specific disability-free life expectancy (DFLE) for urban and rural areas of Bangladesh, as well as to investigate the differences in DFLE between males and females of urban and rural areas. METHODS: Data from the Bangladesh Sample Vital Statistics-2016 and the Bangladesh Household Income and Expenditure Survey (HIES)-2016 were used to calculate the disability-free life expectancy (DFLE) of urban and rural males and females in Bangladesh in 2016. The DFLE was calculated using the Sullivan method. RESULTS: With only a few exceptions, rural areas have higher mortality and disability rates than urban areas. For both males and females, statistically significant differences in DFLE were reported between urban and rural areas between the ages of birth and 39 years. In comparison to rural males and females, urban males and females had a longer life expectancy (LE), a longer disability-free life expectancy, and a higher share of life without disability. CONCLUSION: This study illuminates stark urban-rural disparities in LE and DFLE, especially among individuals aged < 1-39 years. Gender dynamics reveal longer life expectancy but shorter disability-free life expectancy for Bangladeshi women compared to men, emphasizing the need for targeted interventions to address these pronounced health inequalities.

The impact of physical activity on household out-of-pocket medical expenditure among adults aged 45 and over in urban China: The mediating role of spousal health behaviour.

Background: Increasing medical expenditure is viewed as one of the critical challenges in the context of population ageing. Physical activity (PA), as a primary prevention strategy for promoting health, is considered as an effective way to curb the excessive growth in medical expenditure. This study aimed to analyze the association between PA and the household out-of-pocket medical expenditure (HOPME) among Chinese urban adults aged 45 and over, and to explore the mediating role of spousal health behaviour. Methods: This study analyzed a nationally longitudinal survey: 2014-2018 China Family Panel Studies (CFPS). Fixed effects regression model was applied to estimate the association between PA and annual HOPME. Sobel model was utilized to test the mediating effect. Results: (1) PA was negatively associated with the annual HOPME among urban resident aged 45 and over in China. Exercising 1-5 times per week and maintaining the duration of each exercise session at 31-60 min were effective in reducing annual HOPME. (2) Spousal PA played a significant mediating role in the relationship between respondent's PA and annual HOPME. (3) The negative association between the respondent's PA and HOPME were found among women and those aged between 45 and 65, so was the mediating effect of spouse's PA. Conclusion: Individual PA not only directly reduces HOPME but also indirectly contributes to this reduction by enhancing the PA levels of their spouses. To capitalize on these benefits, more actions should be taken to increase the availability of PA facilities, enhance the public awareness of PA's benefits, and encourage residents to consistently engage in regular PA.

The association between anti-smoking legislation and prevalence of acute respiratory illnesses in Indian children.

Objective: Exposure to tobacco smoke causes numerous health problems in children, and create burden on the population in terms of economy, morbidity and mortality. In order to protect the child from exposure to tobacco smoke in the outdoor environment, sufficient legislative enactments are available in Indian legislation. The objective of the present study is to investigate the fact that in absence of any specific laws stating about protection of children from exposure to tobacco smoke in indoor environment, whether outdoor related legislations are sufficient to protect children from exposureand to explore the scope for enforcement of both state and central laws in improving health of children in India. Study design: The study considered cross-sectional survey data of Demographic and Health Survey Data on India, National Family and Health Survey fourth round (NFHS-4) for the year 2015-16 on Indian children (below age of four). Methods: Both bivariate and multivariate logistic regression models were used to assess the impact of anti-smoking laws on the prevalence of acute respiratory infection (ARI) based on the place of residence, indoor tobacco smoke exposure and age of the child. Results: The results have shown an inclination of ARI among children in association with states having single law, rural area resident, exposure to indoor tobacco smoke and age of the child, both as independent or in combination are quite conspicuous, and are found to be underestimated. The logistic regression also revealed the influence of these factors both as independent and even in interaction with other. Conclusions: Legislative intervention through both at central (or national)and state levels through anti-smoking laws will decrease the indoor tobacco smoke exposure as a result ARI prevalence will also decrease among children in India.

ExoMechHand prototype development and testing with EMG signals for hand rehabilitation.

Rehabilitation is a major requirement to improve the quality of life and mobility of patients with disabilities. The use of rehabilitative devices without continuous supervision of medical experts is increasing manifold, mainly due to prolonged therapy costs and advancements in robotics. Due to ExoMechHand's inexpensive cost, high robustness, and efficacy for participants with median and ulnar neuropathies, we have recommended it as a rehabilitation tool in this study. ExoMechHand is coupled with three different resistive plates for hand impairment. For efficacy, ten unhealthy subjects with median or ulnar nerve neuropathies are considered. After twenty days of continuous exercise, three subjects showed improvement in their hand grip, range of motion of the wrist, or range of motion of metacarpophalangeal joints. The condition of the hand is assessed by features of surface-electromyography signals. A Machine-learning model based on these features of fifteen subjects is used for staging the condition of the hand. Machine-learning algorithms are trained to indicate the type of resistive plate to be used by the subject without the need for examination by the therapist. The extra-trees classifier came out to be the most effective algorithm with 98% accuracy on test data for indicating the type of resistive plate, followed by random-forest and gradient-boosting with accuracies of 95% and 93%, respectively. Results showed that the staging of hand condition could be analyzed by sEMG signal obtained from the flexor-carpi-ulnaris and flexor-carpi-radialis muscles in subjects with median and ulnar neuropathies.

Sedentary behaviour among older adults residing in flat and hilly neighbourhoods and its association with frailty and chronic disease status.

BACKGROUND: Living in hilly neighbourhoods can be associated with sedentary behaviour, but no study has compared sedentary behaviour and its associations with frailty, chronic diseases, and poor health between flat and hilly neighbourhoods among older adults. This study, therefore, compared older adults' sedentary behaviour and its association with frailty, poor health, and chronic disease status between low and hilly neighbourhoods. METHODS: This study utilised a STROBE-compliant cross-sectional design with sensitivity analyses and a common methods bias assessment. The participants were 1,209 people aged 50+ years who resided in flat (Ablekuma North, n = 704) and hilly (Kwahu East, n = 505) neighbourhoods in Ghana. The data were analysed with the independent samples t-test and hierarchical linear regression. RESULTS: Older adults in the hilly neighbourhood were more sedentary than those in the flat neighbourhood. The association between sedentary behaviour and chronic disease status was significant in both neighbourhoods, but this relationship was stronger in the hilly neighbourhood. Older adults in the flat neighbourhood reported lower sedentary behaviour at higher frailty (ß = -0.18; t = -3.2, p < 0.001), but those in the hilly neighbourhood reported higher sedentary behaviour at higher frailty (ß = 0.16; t = 3.54, p < 0.001). CONCLUSIONS: Older adults living in the hilly neighbourhood reported higher sedentary behaviour. In the hilly neighbourhood, sedentary behaviour was more strongly associated with frailty and chronic disease status. Older adults in hilly neighbourhoods may need extra support to avoid sedentary behaviour.

Associations of frailty with partial and absolute sedentary behaviours among older adults: A STROBE-compliant analysis of modifiability by gender and age.

BACKGROUND: Research shows that frailty is associated with higher sedentary behaviour, but the evidence to date regarding this association is inconclusive. This study assessed whether the above association is moderated or modified by gender and age, with sedentary behaviour measured with a more inclusive method. METHODS: This study adopted a STROBE-compliant cross-sectional design with sensitivity analyses and measures against common methods bias. The participants were community-dwelling older adults (mean age = 66 years) in two Ghanaian towns. A self-reported questionnaire was used to collect data from 1005 participants after the minimum sample size necessary was calculated. The hierarchical linear regression analysis was used to analyse the data. RESULTS: After adjusting for the ultimate confounders, frailty was associated with higher sedentary behaviour (ß = 0.14; t = 2.93; p <0.05) as well as partial and absolute sedentary behaviour. Gender modified the above associations in the sense that frailty was more strongly associated with sedentary behaviour among women, compared with men. Age also modified the association between frailty and sedentary behaviour, which suggests that frailty was more strongly associated with higher sedentary behaviour at a higher age. CONCLUSION: Sedentary behaviour could be higher at higher frailty among older adults. Frailty is more strongly associated with sedentary behaviour at a higher age and among women, compared with men.

Systematic Literature Review of the Prevalence, Pattern, and Determinant of Multimorbidity Among Older Adults in Nigeria.

Introduction: Multimorbidity is a rising health issue globally and it is likely to become challenging in developing countries like Nigeria as they experience economic, demographic, and epidemiological transition. Yet, evidence of prevalence and patterns of multimorbidity, and their determinants, are scarce. This study aims to systematically review studies of the prevalence, patterns, and determinants of multimorbidity in Nigeria. Methods: Studies were identified by searching 5 electronic databases (PubMed, Web of Science, CINAHL, PsycINFO, Africa Index Medicus/Global Index Medicus). Multimorbidity as well as other versions of it was used to search. The prevalence and determinants were also searched. According to preestablished inclusion criteria, and using different search strategies, 6 articles were included. The quality and risk of bias were assessed using Joanna Briggs Institute appraisal tool for prevalence studies. Two researchers assessed the eligibility of studies for inclusion. The protocol was registered on PROSPERO Ref no. CRD42021273222. The overall prevalence, pattern, and determinants were analyzed. Results: We identified 6 eligible publications describing studies that included a total of 3332 (men 47.5%, women 52.5%) patients from 4 states plus the federal capital territory Abuja. The multimorbidity prevalence ranges from 27% to 74% among elderly Nigerians. Cardiovascular together with metabolic and/or musculoskeletal conditions were the frequent patterns of multimorbidity. A positive association was observed between age and multimorbidity in most studies. Other factors associated with multimorbidity were female gender, low education status, poor monthly income/unemployment, hospitalization, medical visits, and emergency services. Conclusion: There has been a growing need for more applied health services research to understand better and manage multimorbidity in developed countries. The scarcity of studies in our review reveals that multimorbidity is not a priority area of research in Nigeria, and this will continue to hinder policy development in that area.

Exploring the association between attitudes towards wife beating and intimate partner violence using a dyadic approach in three sub-Saharan African countries.

OBJECTIVE: The present study examines the association between attitudes towards wife beating and intimate partner violence (IPV) using a dyadic approach in three sub-Saharan countries. SETTING: We use data from the most recent Demographic and Health Survey cross-sectional studies which were conducted between 2015 and 2018 in Malawi, Zambia and Zimbabwe PARTICIPANTS: Our sample comprised 9183 couples who also had completed the information on the domestic violence questions and our variables of interest. RESULTS: Our results indicate that women in these three countries are generally comparatively more inclined to justify marital violence than their husbands or partners. In terms of IPV experience, we found that when both partners endorsed wife beating, the risk of experiencing IPV was twice as likely after controlling for other couple-level and individual factors (OR=1.91, 95% CI 1.54-2.50, emotional violence; OR=2.42, 95% CI 1.96-3.00, physical violence; OR=1.97, 95% CI 1.47-2.61, sexual violence). The risk of IPV was also higher when the women alone endorsed IPV (OR=1.59, 95% CI 1.35-1.86, emotional violence; OR=1.85, 95% CI 1.59-2.15, physical violence; OR=1.83, 95% CI 1.51-2.22, sexual violence) than when the men alone were tolerant (OR=1.41, 95% CI 1.13-1.75, physical violence; OR=1.43, 95% CI 1.08-1.90, sexual violence). CONCLUSIONS: Our findings confirm that attitudes towards violence are perhaps one of the key indicators of IPV prevalence. Therefore, to break the cycle of violence in the three countries, more attention must be paid to attitudes towards the acceptability of marital violence. Programmes tailored to gender role transformation and promote non-violent gender attitudes are also needed.

Evaluation of concordance in estimation of excess mortality due to COVID-19 pandemic.

BACKGROUND: The World Health Organization (WHO) kept track of COVID-19 data at country level daily during the pandemic that included the number of tests, infected cases and fatalities. This daily record was susceptible to change depending on the time and place and impacted by underreporting. In addition to reporting cases of excess COVID-19-related deaths, the WHO also provided estimates of excess mortality based on mathematical models. OBJECTIVE: To evaluate the WHO reported and model-based estimate of excess deaths to determine the degree of agreement and universality. METHODOLOGY: Epidemiological data gathered from nine different countries between April 2020 and December 2021 are used in this study. These countries are India, Indonesia, Italy, Russia, United Kingdom, Mexico, the United States, Brazil and Peru and each of them recorded more than 1.5 million deaths from COVID-19 during these months. Statistical tools including correlation, linear regression, intraclass correlation and Bland-Altman plots are used to assess the degree of agreement between reported and model-based estimates of excess deaths. RESULTS: The WHO-derived mathematical model for estimating excess deaths due to COVID-19 was found to be appropriate for only four of the nine chosen countries, namely Italy, United Kingdom, the United States and Brazil. The other countries showed proportional biases and significantly high regression coefficients. CONCLUSION: The study revealed that, for some of the chosen nations, the mathematical model proposed by the WHO is practical and capable of estimating the number of excess deaths brought on by COVID-19. However, the derived approach cannot be applied globally.

Prevalence, determinants and consequences of problematic smartphone use among preschoolers (3-5 years) from Dhaka, Bangladesh: A cross-sectional investigation.

The problematic smartphone use (PSU) has been becoming a challenging health issue for preschoolers aged 3-5 years as it has severe adverse effect on their psychological, physical, and cognitive development. The scarcity of scientific research on this issue in the context of Bangladesh motivated the authors for conducting this cross-sectional study to explore the prevalence of PSU with its influential factors and adverse effects on preschooler's psychological and physical development based on primary data collected from 400 mothers. The multivariable ordinal logistic regression (OLR) was used to compute the adjusted likelihoods. The estimated prevalence of PSU was approximately 86 %, where about 29 % were severely problematic user. The likelihood of preschoolers' PSU was observed to increase with >1 h/day usage of smartphone by children (Adjusted Odds Ratio (AOR): 3.92). Other important factors were parental smartphone use, education, profession, family income, and mother's age. Both of moderate and severe PSU had adverse effect on preschoolers' health- severe PSU was found to increase the likelihood of psychological and physical problems by 6.03 and 3.29 times, respectively. The preschoolers with PSU reported to suffer from many physical and mental health problems such as attention deficit and hyperactivity disorder (ADHD), emotional instability, aggressiveness, depression, lack of control, impaired vision and hearing, obesity, body imbalance, and lack of brain development. It is now prime time to undertake strategic policies considering the findings for limiting the preschoolers' usage of smartphone, which will make Bangladesh susceptible to protect its future generation from harmful effects of PSU.

The experience of living alone as an older woman in the UK during the Covid pandemic: an interpretative phenomenological analysis.

BACKGROUND AND OBJECTIVES: More people are living alone across the life course: in later life this can have implications for practical and psychosocial support. The Covid pandemic emphasised the importance of this when the UK government restricted movement outside of households to limit the spread of disease. This had important ramifications regarding social contact and practical support. The objectives of this study were to explore the experience of older women living alone during this time, with a focus on health and wellbeing. RESEARCH DESIGN AND METHODS: This study used an Interpretative Phenomenological approach. Semi-structured interviews were undertaken with seven women (aged 65 +), living alone in the UK. Interviews were carried out between May and October 2020. Interpretative Phenomenological Analysis was used to analyse the transcripts. RESULTS: Findings show that life course events shaped how living alone was experienced in later life. Convergences and divergences in lived experience were identified. Three superordinate themes emerged from the Interpretative Phenomenological Analysis: Productivity, Ownership, and Interconnectedness. DISCUSSION AND IMPLICATIONS: Findings highlight the importance of life course events in shaping the experience of later life. They also provide a better understanding of the lived experience of living alone as an older woman, increasing knowledge of this group and how living alone can affect health and wellbeing. Implications for research and practice are discussed, such as the importance of recognising the specific support needs for this group in later life, and the need for further knowledge about groups whose needs are not met by standard practice.

Association between fear of falling and self-care behaviours of older people with hypertension.

AIM: This study investigated the association between fear of falling and self-care behaviours of older people with hypertension. DESIGN: A cross-sectional study. METHODS: This study was conducted in 2019 on 301 older people with hypertension above the age of 60 years in Tehran, Iran. Data were collected using a demographic questionnaire, the Persian Falls Efficacy Scale-International, and a hypertension-related self-care behaviour questionnaire. RESULTS: Analyses revealed that gender, educational level and history of falling were significant factors associated with fear of falling; and marital status, educational level and income source were significant factors associated with self-care behaviours (p < 0.05). Partial correlations controlling for education revealed a significant positive correlation showing that high fear of falling is associated with worse health promotion self-care behaviours and significant inverse correlations with psycho-emotional, social and daily self-care behaviours (p < 0.05), meaning that high fear of falling is associated with better self-care for these dimensions. PATIENT OR PUBLIC CONTRIBUTION: This study involved patients in order to evaluate the validity and reliability of the questionnaires. The study was conducted on older people with hypertension referred to hypertension clinics in hospitals.

Socially active neighborhoods: construct operationalization for aging in place, health promotion and psychometric testing.

From the year 2003 when the first walkability scale was published to date, person-environment fit models and empirical research, some of which was published in Health Promotion International, have encapsulated healthy communities in 'neighborhood walkability'. While there is no doubt that neighborhood walkability positively influences health-seeking behaviors and health, recent models suggest that their measurement and conceptualization have not emphasized the role played by psychosocial and personal factors in aging in place. Thus, the development of scales measuring human ecosystem factors has not recognized all critical factors suited for older adults. In this paper, we aim to draw on relevant literature to frame a more holistic construct, hereby referred to as Socially Active Neighborhoods (SAN), that would better support aging in place in older populations. Through a narrative review based on a systematic search of the literature, we define the scope of SAN and delineate some contextual implications for gerontology, health promotion and psychometric testing. SAN, unlike neighborhood walkability in its current measurement and conceptualization, incorporates critical theory-informed psychosocial factors (i.e. safety and disability friendliness of neighborhood infrastructure) that can encourage older adults with physiological and cognitive limitations to maintain physical and social activities as well as health in later life. The SAN is the result of our adaptation of key person-environment models, including the Context Dynamics in Aging (CODA) framework, that recognizes the role of context in healthy aging.

Associations of Social Networks with Physical Activity Enjoyment among Older Adults: Walkability as a Modifier through a STROBE-Compliant Analysis.

The available evidence suggests that social networks can contribute to physical activity (PA) enjoyment, which is necessary for the maintenance of PA over the life course. This study assessed the associations of active and sedentary social networks with PA enjoyment and ascertained whether walkability moderates or modifies these associations. A cross-sectional design compliant with STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) was employed. The participants were 996 community-dwelling older Ghanaians aged 50 years or older. A hierarchical linear regression analysis was used to analyse the data. After adjusting for age and income, the study found that the active social network size (ß = 0.09; p < 0.05) and sedentary social network size (ß = 0.17; p < 0.001) were positively associated with PA enjoyment. These associations were strengthened by walkability. It is concluded that active and sedentary social networks may better support PA enjoyment in more walkable neighbourhoods. Therefore, enabling older adults to retain social networks and live in more walkable neighbourhoods may be an effective way to improve their PA enjoyment.

Older Women Living Alone in the UK: Does Their Health and Wellbeing Differ from Those Who Cohabit?

With an increased prevalence of people living alone in later life, understanding the health and wellbeing of older women living alone in the UK is an important area of research. Little is known about health and wellbeing in this population and whether they differ from those who cohabit. This paper fills this research gap. Analysis was undertaken of Wave 8 of the Understanding Society Household Panel Survey, including variables such as internet use and volunteering. Differences were found between those who live alone and cohabit. Volunteering was a predictor of better health outcomes for those who lived alone but not for those who cohabit, despite similar rates of volunteering. Internet use predicted some better health outcome for those who cohabit but poorer for those who live alone. This suggests lifestyle factors vary in how they affect the health and wellbeing of older women, depending on cohabitation status.

Older Adults' Vigorous Occupational Physical Activity Levels in Six Countries Are Explained by Country and 'Having Multiple Jobs'.

Several studies have compared physical activity (PA) levels between countries, but none of these studies focused on older adults and occupational PA. This study aimed to assess potential inequalities in older adults' occupational PA across six countries and to ascertain whether having multiple jobs is a factor that interacts with country of residence to modify inequalities. This study adopted a cross-sectional design with a statistical technique screening for potential covariates. Older adults (mean age = 64 years; range = 50-114 years) from six countries (Russia, Mexico, China, India, Ghana, and South Africa) participated in the study. We utilised data from the first wave of the Study on Global AGEing and Adult Health (SAGE). These data were collected from 2007 to 2010. A random sample of 34,114 older adults completed the survey. We analysed the data with a two-way multivariate analysis of variance after screening for the ultimate covariates. There were differences in occupational PA levels (i.e., vigorous and moderate PA) among the six countries. Occupational PA levels were not significantly associated with having multiple jobs. However, having multiple jobs interacted with country of residence to influence vigorous occupational PA. Older adults from most countries who had more than one job reported more vigorous occupational PA. Older adults' occupational PA differed among the six countries, and having multiple jobs was associated with more vigorous occupational PA. Older adults who keep multiple jobs at a time may be more active than their counterparts who had one job or were unemployed.

Stochastic mortality forecasts for Bangladesh.

Mortality forecasts are essential part for policymaking in any aging society. In recent years, methods to model and forecast mortality have improved considerably. Among them, Lee-Carter method is one of the most influential method. In this paper, Lee-Carter method is applied to forecast mortality and life expectancy of Bangladesh. A functional data analysis approach is used to decompose the smoothed log-mortality rates in Lee-Carter framework for higher goodness-of-fit of the models and for longer forecast horizons. Bangladesh has been experiencing a mortality transition and has gained life expectancy in last few decades. The fitted model here showed higher pace of mortality decline for women in Bangladesh than that of men. The forecasts showed continuation of mortality improvement in long run and by 2060 life expectancy at birth is expected to reach over 80 years for both sexes in Bangladesh. The study also predicts the effect of reduction in infant mortality on the life expectancy in Bangladesh.

Prevalence and correlates of severe under-5 child anthropometric failure measured by the composite index of severe anthropometric failure in Bangladesh.

Background: Although Bangladesh has made noticeable progress in reducing the prevalence of stunting, wasting, and being underweight among under-5 children, it has not been very successful in reducing overall severe anthropometric failure (SAF) among them. Therefore, the study aims to identify the prevalence and risk factors of SAF measured by the Composite Index of Severe Anthropometric Failure (CISAF) among under-5 children in Bangladesh. Methods: Data was drawn from a cross-sectional Bangladesh Demographic Health Survey (BDHS) conducted in 2017-2018. A bivariate analysis (Chi-square test) and logistic regression analysis were used to estimate the unadjusted, and age and sex-adjusted prevalence of SAF. Odds ratio (OR) and confidence interval (CI) were assessed using logistic regression analysis to identify the various risk factor of SAF. Results: The overall adjusted prevalence of under-5 child SAF was 11.3% (95% CI: 10.6-12.0) and it was highly prevalent among children of uneducated mothers (adjusted, 22%, 95% CI: 17.3-26.8). The key factors associated with SAF were children in the age group 24-35 months (OR: 2.43, 95% CI: 1.83-3.23), children born with low birth weight (OR: 3.14, 95% CI: 2.24-4.97), children of underweight mothers (OR: 1.82, 95% CI: 1.44-2.29), children of parents with no formal education (OR: 2.28, 95% CI: 1.56-3.31) and children from lower socio-economic status (OR: 2.25, 95% CI: 1.55-3.26). Conclusion: Prioritizing and ensuring context-specific interventions addressing individual, community, public policy, and environment level risk factors from policy level to implementation to reduce structural and intermediary determinants of under-5 SAF.

Effective Hospital Care Delivery Model for Older People in Nigeria with Multimorbidity: Recommendations for Practice.

The importance of developing an effective action-based model of care for multimorbid patients has become common knowledge, but it remains unclear why researchers in Nigeria have not paid attention to the issue. Hence, this study assessed the quality of health services using the Donabedian model and aimed to recommend an effective hospital care delivery model for older people in Nigeria with multimorbidity. A cross-sectional study using face-to-face data was conducted between October 2021 and February 2022. The reported data were collated, checked, coded, and entered into JISC online survey software and then exported to IBM Statistical Package for Social Science (SPSS) version 27 for analysis, sourced from the University of West London, London, United Kingdom. The data were collected from the outpatient department of four high-volume public secondary hospitals in Niger State (the largest hospital in the three senatorial zones and that of the state capital). Systematic random sampling was used to select 734 patients with two or more chronic diseases (multimorbidity) aged 60 years and above who presented for routine ambulatory outpatient and consented to participate in the study. A Service Availability and Readiness Assessment (SARA) tool was used to assess the structure, and the process quality was assessed by the patients' experiences as they navigated the care pathway, whereas the outcome was measured using the patients' overall satisfaction. Using Spearman's correlation, no statistically significant association was observed between satisfaction level with the healthcare that was received and the five domains of health facility readiness (Total score Basic Amenities, Total score Basic Equipment, Total score infection control, Total score diagnostic capacity, Total score essential drugs), and the general facility readiness. Finally, the process component superseded the structure as the determinant of the quality of healthcare among multimorbid patients in Niger State. The emphasis of the process should be on improving access to quality of care, improving patient-physician relationships and timing, reducing the financial burden of medical care, and building confidence and trust in medical care. Therefore, these factors should be incorporated into designing the healthcare model for multimorbid patients in Nigeria.

Characterization and performance evaluation of Cu-based/TiO2 nano composites.

Copper and copper alloys are used in industrial applications and food contact surfaces due to their desirable properties; copper metal matrix composites have been exciting researchers' attention in recent years since they can offer many valuable characteristics. The present study investigated the effects of the TiO2 nanoparticles addition with different weight percent on the hardness and corrosion behavior of copper nanocomposites. The powder metallurgy method was used to fabricate the Cu/TiO2 reinforced with different weight fractions of TiO2 nano particles up to 12 wt.%. The corrosion behavior of fabricated specimens is evaluated using potentiodynamic polarization curves and electrochemical impedance spectroscopy in different solutions. These solutions were 3.5wt.% NaCl, 0.5 NaOH and 0.5 M H2SO4 reflected different pH. The results showed that the addition of TiO2 nano particles improves pure copper's hardness. The hardness of pure copper increased from 53 to 91 HV by adding 12 wt.% TiO2. The corrosion current density (Icorr) of copper nanocomposites test specimens was higher than Icorr of pure copper in all test solutions. As TiO2 nano particles increase, the corrosion resistance of Cu nano composites decreased. All test specimens exhibited little corrosion current density in 3.5 wt.% NaCl solution as compared with other test solutions.
