The household financial burden of non-communicable diseases in low- and middle-income countries: a systematic review

Systematic literature review on reinforcement learning in non-communicable disease interventions

There is evidence that reducing modifiable risk factors and strengthening medical and health interventions can reduce early mortality and economic losses from non-communicable diseases (NCDs). Machine learning (ML) algorithms have been successfully applied to preventing and controlling NCDs. Reinforcement learning (RL) is the most promising of these approaches because of its ability to dynamically adapt interventions to NCD disease progression and its commitment to achieving long-term intervention goals. This paper reviews the preferred algorithms, data sources, design details, and obstacles to clinical application in existing studies to facilitate the early application of RL algorithms in clinical practice research for NCD interventions. We screened 40 relevant papers for quantitative and qualitative analysis using the PRISMA review flow diagram. The results show that researchers tend to use Deep Q-Network (DQN) and Actor-Critic as well as their improved or hybrid algorithms to train and validate RL models on retrospective datasets. Often, the patient's physical condition is the main defining parameter of the state space, while interventions are the main defining parameter of the action space. Mostly, changes in the patient's physical condition are used as a basis for immediate rewards to the agent. Various attempts have been made to address the challenges to clinical application, and several approaches have been proposed from existing research. However, as there is currently no universally accepted solution, the use of RL algorithms in clinical practice for NCD interventions necessitates more comprehensive responses to the issues addressed in this paper, which are safety, interpretability, training efficiency, and the technical aspect of exploitation and exploration in RL algorithms.

Drug repurposing for metabolic disorders: Scientific, technological and economic issues

Obesity, diabetes, and other metabolic disorders place a huge burden on both the physical health and financial well-being of the community. While the need for effective treatment of metabolic disorders remains urgent and the reality is that traditional drug development involves high costs and a very long time with many pre-clinical and clinical trials, the need for drug repurposing has emerged as a potential alternative. Scientific evidence has shown the anti-diabetic and anti-obesity effects of old drugs, which were initially utilized for the treatment of inflammation, depression, infections, and even cancers. The drug library used modern technological methods to conduct drug screening. Computational molecular docking, genome-wide association studies, or omics data mining are advantageous and unavoidable methods for drug repurposing. Drug repurposing offers a promising avenue for economic efficiency in healthcare, especially for less common metabolic diseases, despite the need for rigorous research and validation. In this chapter, we aim to explore the scientific, technological, and economic issues surrounding drug repurposing for metabolic disorders. We hope to shed light on the potential of this approach and the challenges that need to be addressed to make it a viable option in the treatment of metabolic disorders, especially in the future fight against metabolic disorders.

Exploring the lived experiences of family caregivers of patients with stroke in Africa: a scoping review of qualitative evidence

OBJECTIVE

The burden of stroke is immense in African countries, with post-stroke care usually becoming the responsibility of family. This review sought to determine the current breadth and depth of qualitative evidence regarding the lived experiences of family caregivers of patients with stroke in Africa.

METHODS

Informed by Joanna Briggs Institute (JBI) methodology for scoping reviews, six databases were searched. Included articles were appraised for quality using the JBI checklist. A priori themes developed using the study objectives were used to synthesize study findings.

RESULTS

The review included 22 articles, which outlined key patterns in stroke outcomes with most articles focused on rehabilitation and the experiences, outcomes, burdens, and coping mechanisms of caregiving. The intersectionality of socio-economic status, socio-political structures, and religious or traditional beliefs, attitudes, and practices characterized etiology beliefs, treatment trajectories of stroke, and caregiving role assignment. Whereas burdens were driven by limited resources, adopted coping strategies involved spiritual or religious beliefs, optimism, resilience, and social support networks.

CONCLUSIONS

Family caregivers' values must be acknowledged, supported, and integrated into the traditional healthcare system to provide comprehensive stroke care. Caregivers' health and well-being should be given more attention given their necessary contribution to stroke survivorship in Africa.

Intake of Table Sugar and Their Corresponding Food Sources in Adults from the 2017-2018 Brazilian National Dietary Survey

Excessive intake of free sugars is associated with adverse health outcomes. Table sugar is one of the main dietary sources of free sugars; however, the amount added by Brazilian consumers in their culinary preparations is unknown. The aims were to estimate the daily intake of table sugar (g/day), its contribution to total energy intake (E%) and the main food groups that contribute to the intake of this sugar in a nationwide multi-ethnic sample of Brazilian adults (2017-2018 Brazilian National Dietary Survey). Based on two 24-h recalls adjusted for the within-person variation, the overall median table sugar intake was 14.3 g/day, corresponding to 3.2 E%. Males, individuals living in rural areas, with low income, low education and experiencing food insecurity had a higher intake of table sugar. The main food sources of table sugar were coffee (55.8%), juice (33.9%), milk-based preparations and smoothies (3.1%), powdered and processed juice (2.7%), whole milk (1.9%), and tea (1.6%). There are no recommendations regarding the limit of table sugar intake, but considering that the WHO limits the intake of free sugars to <10 E%, it is concluded that table sugar intake by Brazilians corresponds to about 30% of the upper recommended daily intake of free sugars.

Economic priorities over population health: A political dilemma in addressing noncommunicable diseases in developing countries

The world is observing a rapid shift in the burden of diseases with predominance of noncommunicable diseases (NCDs). NCDs contribute to 41 million deaths which is equivalent to 74% of all death globally per year. There is ongoing debate on the approaches to reduce public exposure to NCDs' modifiable risk factors which are of economic potential. As the World Health Organization and the World Bank recommend the implementation of taxation to these factors, still questions arise on the effectiveness, sustainability, and practicality of this strategy. With the ongoing transition globally from consumption of natural to processed foods, it is important to counter-check the best interventions on how to protect people from unhealthy eating behaviors. While taxation on unhealthy food and other products like tobacco has been recommended as one among interventional approaches, its effectiveness on sugar sweetened beverages is not reliable compared to approaches that increase self-control. Despite the perceived economic benefits of tobacco and sugar sweetened products, there is detrimental implication in terms of public health. The introduction of taxation which favors public health faces challenges due to conflict of interest from government authorities and other stakeholders. The intertwined relationship between public health and economic development becomes more obvious during implementation of preventive and control measures against modifiable risk factors for NCDs. It is evident that reaching a balanced rational decision on choosing between economic growth and public health is difficult. Countries should enhance both local and international intersectoral and multisectoral approaches in creating integrative policies which include health component in all non-health policies including economic policies so as to harmonize public health and economic growth during this era of extensive globalization.

Inequalities in non-communicable disease management in China and progress toward universal health coverage: an analysis of nationwide household survey data from 2004 to 2018

Background

Prevention and control of non-communicable diseases (NCDs) become a policy priority in Universal Health Coverage (UHC) in China, while NCD management has never been comprehensively estimated at national and subnational levels. We aimed to assess NCD management in China nationally and in key subpopulations, investigate inequalities from multidimensions, and further examine its association with health financing and resources.

Methods

Data included were from China Chronic Disease and Risk Factors Surveillance (CCDRFS) and China Health and Nutrition Survey (CHNS). Following the WHO recommended frameworks, we selected eight NCD health service and risk management indicators and used meta-analysis to construct the composite NCD index. We explored the trends in and projections of NCD management index and indicators at national and subnational levels by using Bayesian regression models with average annual percentage change (AAPC) from 2004 to 2018 and probability of reaching the UHC target by 2030. We further conducted comprehensive inequality analyses of NCD indicators from multidimensions with patterns of changes over time using absolute difference and relative ratio. Finally, we quantified the associations between NCD management performance with health financing and resources using stochastic frontier analysis.

Findings

In China, the NCD management index increased slowly from 62.0% (95% CI 36.0 to 84.0) in 2004 to 64.3% (95% CI 44.0 to 82.2) in 2018, with lagging performance being observed in prevention domain (AAPC -0.1%, 95% CrI -1.0 to 0.8). And all management indicators presented low probabilities of accomplishing 2030 targets in China. Notably, based on subnational analysis, diverse tendency and magnitude of inequalities in multiple NCD indicators were identified with widening gaps between genders (non-overweight, diabetes treatment), age groups (non-use of tobacco), urban-rural areas (non-use of alcohol, non-use of tobacco), regions (sufficient physical activity), and wealth quintiles (non-overweight, sufficient physical activity). Additionally, it was observed that compared with urban area, rural area had constantly lower health resources and presented 2.2% lower NCD management performance in 2018. Importantly, we found that health financing and resources especially distributed in primary health care (PHC) facilities were closely and positively associated with NCD management performance. A 1000 yuan increase of government health expenditure (GHE) per capita and a 10 increase of medical beds per 1000 capita in PHC facilities were associated with a 4.0% (95% CI 2.0 to 6.0) and 6.8% (95% CI 0.2 to 13.5) increase of NCD management index, respectively.

Interpretation

The progress towards NCD management is slow at national level and in key subpopulations in China, with great challenges of existing and widening inequalities between genders, age groups, urban-rural areas, regions and socioeconomic groups. Rural and old people were still vulnerable populations who were lagging behind in NCD prevention and control. Optimising resource allocation by strengthening PHC especially in rural area, developing tailor-made programmes targeting specific populations such as old individuals, simultaneously integrating gender, education, and economic interventions to reduce inequalities should be prioritised to help China tackle NCDs during the progress towards UHC.

Trends in major non-communicable diseases and related risk factors in China 2002-2019: an analysis of nationally representative survey data

Background

Prevention and control of non-communicable diseases (NCDs) are prioritized in both the Sustainable Development Goal and the Healthy China 2030 Initiatives. Efforts have been devoted to combating NCDs in China. This study examined changes in NCD trajectory.

Methods

We described and analyzed the trends in prevalence and control of major NCDs including obesity, hypertension, diabetes, and dyslipidemia and examined selected main behavioral risk factors in China by sex, age group, and residence using nationally representative CDC survey data. Data included were from the China Chronic Disease Risk Factor Surveillance (CCDRFS, 2013 and 2018) and China National Nutrition Survey (CNNS, 2002, 2010-2013, 2015, and 2020). Annual and relative changes in rates were used. Rural-urban ratio of related indicators was assessed.

Findings

NCD-attributed deaths increased from 80.0% in 2002 to 86.6% in 2012, and 88.5% in 2019, with cardiovascular diseases, cancer, chronic respiratory diseases, and diabetes accounted for 47.1%, 24.1%, 8.8%, and 2.5% of deaths in 2019, respectively. Prevalence of obesity (7.1%-16.4%), overweight/obesity (29.9%-50.7%), hypertension (18.8%-27.5%), diabetes (2.6%-11.9%), and dyslipidemia (18.6%-35.6%) all increased from 2002 to 2018. These rates increased faster in rural areas than in urban areas. Rates of awareness, treatment and control of hypertension and diabetes increased very slowly from 2012 to 2018. Most rates were between 30 and 40% with the lowest rate of 11% for hypertension control even in 2018. The rates were worse for rural residents compared to urban residents. Furthermore, many modifiable behavioral risk factors showed little improvement and some became worse over time, including smoking, excessive alcohol use, inadequate vegetable/fruit intake, excessive red meat intake, and physical inactivity.

Interpretation

NCD burden in China increased during 2002-2019 despite of the intervention efforts. To reach the global and national targets, China must strengthen its actions, especially in rural areas, including improvement of NCD screening and management and reduction of behavioral risk factors.

Funding

The study was supported in part by research grants of National Key R&D Program of China (2017YFC0907200, 2017YFC0907201), International Collaboration Project from the Chinese Ministry of Science and Technology-Prevention and control of chronic diseases and health promotion (G2021170007L), Natural Scientific Foundation of China (82103846), Key R&D and Transformation Program of Qinghai (2023-QY-204).

Multimorbidity and its associated risk factors among adults in northern Sudan: a community-based cross-sectional study

BACKGROUND

Multimorbidity (having two or more coexisting long-term conditions) is a growing global challenge. However, data on multimorbidity among adults in Africa, including Sudan, are scarce. Thus, this study aimed to investigate the prevalence of multimorbidity and its associated risk factors among adults in Sudan.

METHODS

A community-based cross-sectional study was conducted in northern Sudan from March 2022 to May 2022. Participants' sociodemographic characteristics were assessed using a questionnaire. Multimorbidity was defined as having two or more coexisting long-term conditions, including diabetes mellitus (DM), hypertension, obesity, anaemia and depression-anxiety. Multivariate logistic regression analyses were performed to determine the associated factors.

RESULTS

The participants included 250 adults: 119 (47.6%) males and 131(52.4%) females. The median interquartile range (IQR) of the enrolled adults of the age was 43.0 (30.0‒55.0) years. Of the 250 adults, 82(32.8%), 17(6.8%), 84(33.6%), and 67(26.8%) were normal weight, underweight, overweight, and obese, respectively; 148(59.2%), 72(28.8%), 63(25.2%), 67(26.8%), and 98(39.2%) had hypertension, DM, anaemia, obesity, and depression-anxiety, respectively. A total of 154 adults (61.6%) had multimorbidity: 97(38.8%), 49(19.6%), and 8(3.2%) had two, three, and four morbidities, respectively. The remaining 21 (8.4%), and 75 (30.0%) adults had no morbidity, and one morbidity, respectively. In amultivariate logistic regression analysis, increasing age (adjusted odd ratio [AOR] = 1.03, 95% CI = 1.01‒1.05), and female sex (AOR = 2.17, 95% CI = 1.16‒4.06) were associated with multimorbidity.

CONCLUSIONS

The high prevalence of multimorbidity revealed in this study uncovers a major public health problem among Sudanese adults. Our results show that increasing age and female sex are associated with multimorbidity. Additional extensive studies are necessary to evaluate the magnitude of multimorbidity for improved future planning and establishing effective health systems.

Design, Synthesis, In Vitro, and In Silico Studies of New N5-Substituted-pyrazolo[3,4-d]pyrimidinone Derivatives as Anticancer CDK2 Inhibitors

CDK2 is a key player in cell cycle processes. It has a crucial role in the progression of various cancers. Hepatocellular carcinoma (HCC) and colorectal cancer (CRC) are two common cancers that affect humans worldwide. The available therapeutic options suffer from many drawbacks including high toxicity and decreased specificity. Therefore, there is a need for more effective and safer therapeutic agents. A series of new pyrazolo[3,4-d]pyrimidine analogs was designed, synthesized, and evaluated as anticancer agents against the CRC and HCC cells, HCT116, and HepG2, respectively. Pyrazolo[3,4-d]pyrimidinone derivatives bearing N5-2-(4-halophenyl) acetamide substituents were identified as the most potent amongst evaluated compounds. Further evaluation of CDK2 kinase inhibition of two potential cytotoxic compounds 4a and 4b confirmed their CDK2 inhibitory activity. Compound 4a was more potent than the reference roscovitine regarding the CDK2 inhibitory activity (IC50 values: 0.21 and 0.25 µM, respectively). In silico molecular docking provided insights into the molecular interactions of compounds 4a and 4b with important amino acids within the ATP-binding site of CDK2 (Ile10, Leu83, and Leu134). Overall, compounds 4a and 4b were identified as interesting CDK2 inhibitors eliciting antiproliferative activity against the CRC and HCC cells, HCT116 and HepG2, respectively, for future further investigations and development.

Functional fitness trends among older adults in Portugal between 2008 and 2018: Keeping up with a healthy aging process

OBJECTIVES

Maintaining a healthy aging process is vital to combating and delaying the adverse health outcomes faced by the growing older adult population, where a key aspect to achieving healthy aging is the preservation of functional fitness. This study aims to present trends on the functional fitness of Portuguese older adults between 2008 and 2018 and build new normative reference standards for the Senior Fitness Battery Tests.

DESIGN

Cross-sectional study.

METHODS

Functional fitness was measured with the Senior Fitness Battery Tests in two national representative cohorts of the Portuguese older adult population (≥65 years) using the 2008 (n = 4712) and 2018 (n = 2717) surveys. Changes were assessed according to sex and age group. Sex and age-group normative fitness scores were developed.

RESULTS

Overall findings suggested that older adults' point prevalence for arm-curl, 8-ft up-and-go, and 30-s chair sit-to-stand remained stable between 2008 and 2018, with declining trends being observed for the 6-min walk and back-scratch tests. However, results for trends varied when stratified by sex and age categories.

CONCLUSIONS

Our results suggest a trend toward a stabilization of most of the functional fitness tests over the past decade, but with a critical decline in the 6-min walk test. Thus, this test should be targeted by future health-care policies. Moreover, this investigation provides new and updated normative reference standards for the Senior Fitness Battery Tests that should be used as a tool to promote a healthy aging process among Portuguese older adults.

The economic burden of coronary heart disease in mainland China

OBJECTIVES

The aim of this study was to systematically evaluate the current economic burden of coronary heart disease (CHD) in mainland China and provide a reference for the formulation of policies to reduce the economic burden of CHD.

STUDY DESIGN

A systematic literature review was conducted of empirical studies on the economic burden of CHD over the past 20 years.

METHODS

PubMed, Web of Science, Embase, China Knowledge Resource Integrated Database and the WANFANG database were comprehensively searched for relevant articles published between 1 January 2000 and 22 December 2021. Content analysis was used to extract the data, and Stata 17.0 software was used for analysis. The median values were used to describe trends.

RESULTS

A total of 35 studies were included in this review. The annual median per-capita hospitalisation expense and the average expense per hospitalisation were $3544.40 ($891.64-$18,371.46) and $5407.34 ($1139.93-$8277.55), respectively. The median ratio on medical consumables expenses, drug expenses, medical examination expenses and treatment expenses were 41.59% (12.40%-63.73%), 26.90% (7.30%-60.00%), 9.45% (1.65%-33.40%) and 10.10% (2.36%-66.00%), respectively. The median per-capita hospitalisation expense in the eastern, central and western regions were $9374.45 ($2056.13-$18,371.46), $4751.5 ($2951.95-$8768.93) and $3251.25 ($891.64-$13,986.38), respectively. The median average expense per hospitalisation in the eastern and central regions were $6177.15 ($1679.15-$8277.55) and $1285.49 ($1239.93-$2197.36), respectively. The median average length of stay in the eastern, central and western regions were 9.3 days, 15.2 days and 16.1 days, respectively.

CONCLUSIONS

The economic burden of CHD is more severe in mainland China than in developed countries, especially in terms of the direct economic burden. In terms of the types of direct medical expenses, a proportion of medical examination expenses, treatment expenses and drug expenses were lowest in the eastern region, but medical consumables expenses were the highest in this region. This study provides guidance for the formulation of policies to reduce the economic burden of CHD in mainland China.

Instrumental variable approach on analyzing risk factors associated with noncommunicable disease prevalence in Tanzania: A nonexperimental design

Background and Aims

Noncommunicable diseases (NCDs) have emerged as a substantial burden in developing countries, representing the leading cause of mortality. Addressing this critical issue necessitates effective interventions and policy measures. Therefore, this study aims to investigate the risk factors associated with NCD prevalence in Tanzania.

Methods

This study employed a nonexperimental research design due to its ability to analyze secondary data without altering variables. The used data set of the study was sourced from National Panel Survey 2020/21 and Household Budget Survey 2017/18. The econometrics analysis applied in the study include two-stage residual inclusion (2SRI) and control function approach due to their ability to suppress endogeneity and enhance the clarity of results.

Results

The findings indicate a significant positive correlation between alcohol consumption (0.4110382, p = 0.02), cigarette smoking (0.3354297, p < 0.001), and NCDs, emphasizing the urgency of targeted interventions to mitigate these behaviors. Conversely, a negative correlation is observed between fruit and vegetable intake (-0.1063375, p < 0.001), physical exercises (-0.3744925, p < 0.001), and NCDs, underscoring the importance of promoting healthy dietary habits and frequent exercises.

Conclusion

These results accentuate the immediate need for targeted interventions and policy measures to address these risk factors and effectively combat the escalating burden of NCDs in Tanzania and similar contexts. Moreover, the need for improved public awareness campaigns and the promotion of healthy life campaigns are vital in the fight to lower the prevalence of NCDs across communities.

Catastrophic health care spending in managing type 2 diabetes before and during the COVID-19 pandemic in Tanzania

COVID-19 disrupted health care provision and access and reduced household income. Households with chronically ill patients are more vulnerable to these effects as they access routine health care. Yet, a few studies have analysed the effect of COVID-19 on household income, health care access costs, and financial catastrophe due to health care among patients with type 2 diabetes (T2D), especially in developing countries. This study fills that knowledge gap. We used data from a cross-sectional survey of 500 people with T2D, who were adults diagnosed with T2D before COVID-19 in Tanzania (March 2020). Data were collected in February 2022, reflecting the experience before and during COVID-19. During COVID-19, household income decreased on average by 16.6%, while health care costs decreased by 0.8% and transport costs increased by 10.6%. The overall financing burden for health care and transport relative to household income increased by 32.1% and 45%, respectively. The incidences of catastrophic spending above 10% of household income increased by 10% (due to health care costs) and by 55% (due to transport costs). The incidences of catastrophic spending due to health care costs were higher than transport costs, but the relative increase was higher for transport than health care costs (10% vs. 55% change from pre-COVID-19). The likelihood of incurring catastrophic health spending was lower among better educated patients, with health insurance, and from better-off households. COVID-19 was associated with reduced household income, increased transport costs, increased financing burden and financial catastrophe among patients with T2D in Tanzania. Policymakers need to ensure financial risk protection by expanding health insurance coverage and removing user fees, particularly for people with chronic illnesses. Efforts are also needed to reduce transport costs by investing more in primary health facilities to offer quality services closer to the population and engaging multiple sectors, including infrastructure and transportation.

Economic burden of non-communicable diseases on households in Nigeria: evidence from the Nigeria living standard survey 2018-19

BACKGROUND

The importance of non-communicable diseases (NCDs) in Nigeria is reflected in their growing burden that is fast overtaking that of infectious diseases. As most NCD care is paid for through out-of-pocket (OOP) expenses, and NCDs tend to cause substantial income losses through chronic disabilities, the rising NCD-related health burden may also be economically detrimental. Given the lack of updated national-level evidence on the economic burden of NCDs in Nigeria, this study aims to produce new evidence on the extent of financial hardship experienced by households with NCDs in Nigeria due to OOP expenditure and productivity loss.

METHODS

This study analysed cross-sectional data from the most recent round (2018-19) of the Nigeria Living Standard Survey (NLSS). Household-level health and consumption data were used to estimate catastrophic health expenditure (CHE) and impoverishing effects due to OOP health spending, using a more equitable method recently developed by the World Health Organization European region in 2018. The productivity loss by individuals with NCDs was also estimated from income and work-time loss data, applying the input-based human capital approach.

RESULTS

On average, a household with NCDs spent ₦ 122,313.60 or $ 398.52 per year on NCD care, representing 24% of household food expenditure. The study found that OOP on cancer treatment, mental problems, and renal diseases significantly contribute to the cost of NCD care. The OOP expenditure led to catastrophic and impoverishing outcomes for households. The estimations showed that about 30% of households with NCDs experienced CHE in 2018, using the WHO Europe method at the 40% threshold. The study also found that the cost of NCD medications was a significant driver of CHE among NCD-affected households. The results showed heterogeneity in CHE and impoverishment across states and geographical regions in Nigeria, with a higher concentration in rural and North East geopolitical locations. The study also found that 20% of NCD-affected households were impoverished or further impoverished by OOP payment, and another 10% were on the verge of impoverishment. The results showed a negligible rate of unmet needs among households with NCDs.

CONCLUSIONS

The study highlights the significant effect of NCDs on Nigerian households and the need for effective policy interventions to address this challenge, particularly among the poor and vulnerable.

Patterns of Non-Communicable Disease, Multimorbidity, and Population Awareness in Bahir Dar, Northwest Ethiopia: A Cross-Sectional Study

Objective

Ethiopia, like other developing countries, is going through an epidemiological transition, and high rates of non-communicable diseases (NCDs) are having a significant impact on the health system; however, there is limited evidence about community level NCD prevalence, multimorbidity, and population awareness that could inform targeted interventions and policy responses. This study aimed to identify factors associated with NCD prevalence, multimorbidity, and population awareness of NCDs in Bahir Dar, Northwest Ethiopia.

Methods

A community-based cross-sectional survey was conducted with 417 randomly sampled adults. We performed descriptive and logistic regression analyses to evaluate associations between NCD prevalence (cardiovascular diseases, diabetes, cancer, chronic respiratory diseases, chronic kidney disease, and hypertension) multimorbidity (2 or more NCDs) and demographic, socioeconomic, individual risk factors, anthropometrics, knowledge, and attitude.

Results

This study reveals that 24% of participating adults have an NCD, and 8% have multimorbidity. One-third (34.5%) have some NCD knowledge, and 75% consider NCDs more dangerous than communicable diseases. We find low NCD prevalence in participants: younger than 40 years of age (AOR 0.17, 95% CI 0.07 to 0.39); with normal body mass index (AOR 0.27, 0.10 to 0.77) and; with a family history of NCD (AOR 7.7, 4.2 to 14.1). Multimorbidity is lower in young adults (AOR 0.08, 0.03 to 0.26). NCD knowledge is higher in men (AOR 1.76, 1.06 to 2.93) and employed adults (AOR 2.91, 1.52 to 5.57), and NCD attitude in normal-weight adults (AOR 3.23, 1.42 to 7.39).

Conclusion

This study reveals a high prevalence of NCD and overall low NCD awareness in the population. Age above 40 years, family history of NCD, and weight in the obese category are significant predictors of NCD prevalence. These findings can help health professionals, health offices, and concerned stakeholders to plan targeted health interventions to reduce NCDs in the population.

Out-of-pocket health expenditures in patients living with ınborn errors of metabolism

AIM

The implementation of newborn screening programs for inborn errors of metabolism has advanced the diagnosis and management of affected infants and undoubtedly improved their outcomes. We aimed to determine out-of-pocket health expenditures of patients with inborn errors of metabolism during follow-up and treatment processes and to determine the economic burden on the families.

MATERIALS AND METHODS

A total of 232 patients who voluntarily agreed to participate in the study and were regularly followed up in the Department of Pediatric Metabolism with the diagnosis of Inborn Errors of Metabolism between April 2022 and July 2022 were included. Questionnaires were asked about the demographic characteristics of patients, use of health services, follow-up, treatment procedures, frequency of controls and health expenditures.

RESULTS

The average out-of-pocket expenditure of the households in the last month was 1039.22 ± 1030.08 (minimum: 20, maximum: 5000) Turkish Liras. When we consider the catastrophic health expenditure rate as expenditure exceeding 40% of household income, we found that 9.9% (23 people) of parents included in the study made catastrophic health expenditures. The rate of catastrophic expenditure of patients with a diagnosis of Amino Acid Metabolism Disorders was found to be higher than that of patients with a diagnosis of Vitamin and Cofactor Metabolism Disorders. Similarly, patients with a diagnosis of lysosomal storage diseases had more expenditures than patients with a diagnosis of vitamin and cofactor metabolism disorders. When we compared the rate of catastrophic health expenditure of the patients with urea cycle disorders and the patients with a diagnosis of vitamin and cofactor metabolism disorders, the former had more expenditure than the latter (p < 0.05). There was no significant difference between other disease groups in terms of catastrophic expenditure. The rate of catastrophic expenditures of the households living as large family type were higher than the families living as nuclear family type (p < 0.01). A statistically significant difference was found between the rates of catastrophic expenditures of the families living in Ankara and those who were admitted from other provinces for follow-up and treatment (p < 0.001). However, there was no difference between the rates of catastrophic expenditure of the patients who received any treatment and those who were followed up without treatment (p > 0.05).

CONCLUSION

Due to the high rate of consanguineous marriages in our country, the development of newborn screening programs, the increase in awareness about metabolic diseases and the improvement in diagnostic methods, the frequency of metabolic diseases is increasing, and mortality and morbidity rates are significantly reduced with early diagnosis and treatment opportunities. It is necessary to carry out more comprehensive studies to determine and prevent the socioeconomic effects of out-of-pocket health expenditures of patients living with Inborn Errors of Metabolism.

Examining the responsiveness of the National Health Insurance Fund to people living with hypertension and diabetes in Kenya: a qualitative study

OBJECTIVES

To assess the responsiveness of the National Health Insurance Fund (NHIF) Supa Cover benefit package to the needs of individuals with diabetes and hypertension in Kenya.

DESIGN, SETTING AND PARTICIPANTS

We carried out a qualitative study and collected data using key informant interviews (n=39) and focus group discussions (n=4) in two purposively selected counties in Western Kenya. Study participants were drawn from NHIF officials, county government officials, health facility managers, healthcare workers and individuals with hypertension and diabetes who were enrolled in NHIF. We analysed data using a thematic approach.

RESULTS

Study participants reported that the NHIF Supa Cover benefit package expanded access to services for people living with hypertension and diabetes. However, the NHIF members and healthcare workers had inadequate awareness of the NHIF service entitlements. The NHIF benefit package inadequately covered the range of services needed by people living with hypertension and diabetes and the benefits package did not prioritise preventive and promotive services. Sometimes patients were discriminated against by healthcare providers who preferred cash-paying patients, and some NHIF-empanelled health facilities had inadequate structural inputs essential for quality of care. Study participants felt that the NHIF premium for the general scheme was unaffordable, and NHIF members faced additional out-of-pocket costs because of additional payments for services not available or covered.

CONCLUSION

Whereas NHIF has reduced financial barriers for hypertension and diabetes patients, to enhance its responsiveness to patient needs, NHIF should implement mechanisms to increase benefit package awareness among members and providers. In addition, preventive and promotive services should be included in NHIF's benefits package and mechanisms to monitor and hold contracted providers accountable should be strengthened.

In-depth in-vitro and in-vivo anti-diabetic evaluations of Fagonia cretica mediated biosynthesized selenium nanoparticles

Therapeutic moieties derived from medicinal plants as well as plants-based ecofriendly processes for producing selenium nanoparticles have shown great promise in the management of type 2 diabetes mellitus (T2DM). The current study was aimed to assess the anti-diabetic potentials of Fagonia cretica mediated biogenic selenium nanoparticles (FcSeNPs) using in-vitro and in-vivo approaches. The bio-synthesized FcSeNPs were characterized using various techniques including UV-VIS spectrophotometry and FTIR analysis. The in-vitro efficacy of FcSeNPs were assessed against α-glucosidase, α-amylase enzymes as well as the anti-radical studies were performed using DPPH and ABTS free radicals scavenging assays. For in-vivo studies, 20 Male Balb/C albino-mice were randomly divided into 4 groups (n = 5) including normal group, disease group (Diabetic group with no treatment), control group and treatment group (Diabetic group treated with FcSeNPs). Further, biochemistry markers including pancreas, liver, kidney and lipid profile were assessed for all treatment groups. The FcSeNPs exhibited a dose-dependent inhibition against α-amylase and α-glucosidase at 62-1000 µg mL^-1 concentration with IC₅₀ values of 92 and 100 µg mL^-1 respectively. In antioxidant experiments, the FcSeNPs demonstrated significant radicals scavenging effect against DPPH and ABTS radicals. In STZ-induced diabetic mice, a considerable decline in blood glucose level was observed after treatment with FcSeNPs. Anti-hyperglycemic effect of FcSeNPs treated animals were high (105 ± 3.22**) as compared to standard drug (128.6 ± 2.73** mg dL^-1). Biochemical investigations revealed that all biochemical parameters for pancreas, liver function, renal function panel and lipid profile were significantly lowered in FcSeNPs treated animals. Our findings indicate a preliminary multi-target efficacy for FcSeNPs against type-2 diabetes and thus warrant further detailed studies.

The global burden of metabolic disease: Data from 2000 to 2019

Global estimates of prevalence, deaths, and disability-adjusted life years (DALYs) from the Global Burden of Diseases, Injuries, and Risk Factors Study 2019 were examined for metabolic diseases (type 2 diabetes mellitus [T2DM], hypertension, and non-alcoholic fatty liver disease [NAFLD]). For metabolic risk factors (hyperlipidemia and obesity), estimates were limited to mortality and DALYs. From 2000 to 2019, prevalence rates increased for all metabolic diseases, with the greatest increase in high socio-demographic index (SDI) countries. Mortality rates decreased over time in hyperlipidemia, hypertension, and NAFLD, but not in T2DM and obesity. The highest mortality was found in the World Health Organization Eastern Mediterranean region, and low to low-middle SDI countries. The global prevalence of metabolic diseases has risen over the past two decades regardless of SDI. Urgent attention is needed to address the unchanging mortality rates attributed to metabolic disease and the entrenched sex-regional-socioeconomic disparities in mortality.

The Impact of Free Sugar on Human Health-A Narrative Review

The importance of nutrition in human health has been understood for over a century. However, debate is ongoing regarding the role of added and free sugars in physiological and neurological health. In this narrative review, we have addressed several key issues around this debate and the major health conditions previously associated with sugar. We aim to determine the current evidence regarding the role of free sugars in human health, specifically obesity, diabetes, cardiovascular diseases, cognition, and mood. We also present some predominant theories on mechanisms of action. The findings suggest a negative effect of excessive added sugar consumption on human health and wellbeing. Specific class and source of carbohydrate appears to greatly influence the impact of these macronutrients on health. Further research into individual effects of carbohydrate forms in diverse populations is needed to understand the complex relationship between sugar and health.

Why has the taxing policy on sugar sweetened beverages not reduced their purchase in Iranian households?

Objective

This study aimed at analyzing the effectiveness of the policy of taxing Sugar-Sweetened Beverages (SSBs) on their purchases during the last decade in Iranian households.

Methods

The present mixed method study was done in 2017 in four phases: (1) A meta-review of the fiscal policies during the last decade, (2) Collecting existing data on soft drinks' production, price, and household expenditure during the last decade, (3) Conducting 19 semi-structured interviews with key informants, and (4) Facilitating a national meeting to achieve a consensus on the recommendations and future implications.

Results

Document reviews showed that based on the Permanent Provisions of National Development Plans of Iran, the Ministry of Health and Medical Education (MOHME) should announce the list of health threatening products to increase taxation for them. The government is allowed to impose taxes on domestically produced and imported SSBs. The average household expenditure on SSBs increased in the rural and urban households of Iran during 2006-2016 in spite of taxation. In the different key informants' opinion, only value-added tax (VAT) was implemented among different fiscal policies, and the other parts, including tax and tolls were debated.

Conclusion

The present research findings further proposed some suggestions for increasing the effectiveness of financial policies in reducing the prevalence of NCDs in Iran.

Catastrophic health expenditure on chronic non-communicable diseases among elder population: A cross-sectional study from a sub-metropolitan city of Eastern Nepal

INTRODUCTION

This study was conducted with the objective to analyze the out-of-pocket (OOP) healthcare expenditure and catastrophic healthcare expenditure (CHE) on chronic non-communicable diseases (CNCD) among the elderly population, and the association of CHE on CNCD with associated factors among the same population.

MATERIALS AND METHODS

We collected data from the elderly population of Dharan Sub-metropolitan city of the Eastern Nepal via door-to-door survey and face-to-face interview. The ten wards out of twenty were chosen by lottery method, and the equal proportion out of 280 samples was purposively chosen from each of ten wards (28 participants from each selected ward). The data were entered in Microsoft Excel 2019 v16.0 and statistical analysis was performed by using statistical package for social sciences, IBM SPSS® v21. The chi-square test was used to test the group differences. Multivariable logistic regression was used to determine independent factors associated with CHE (all variables with P < 0.20), and adjusted odds ratios (AOR) were calculated at 95% confidence interval (CI).

RESULTS

The median household, food and health expenditures were 95325 (72112.50-126262.50), 45000 (33000-60000) and 2100 (885.00-6107.50) NPR respectively. The proportion of the participants with CHE was 14.6%. The single living participants had 3.4 times higher odds of catastrophic health expenditure (AOR = 3.4, 95% CI = 1.2-9.6, P-value = 0.022) than those who are married. Similarly, those who had cancer had 0.1 times lower odds of CHE (AOR = 0.1, 95% CI = 0.0-0.2, P-value = <0.001) than those without cancer.

CONCLUSION

The elder population had significant financial health shocks due to chronic health ailments. There should be the provision of mandatory health insurance programmes for elderly to cut down the catastrophic healthcare expenditure. Similarly, there should be the provision of exemption scheme for vulnerable elderly who are more likely to face catastrophic expenditure from all available health facilities.

An economic evaluation of diabetes mellitus in India: A systematic review

BACKGROUND

Approximately 88 million people throughout Southeast Asia have diabetes, of which 77 million reside in India. India had an annual estimated diabetes treatment cost of Rs.10,000 to 12,000 crore in 2003, which is likely to rise to as high as Rs. 1,26,000 crores by 2025.

AIM

To assess the annual mean expenditure for an individual with diabetes mellitus.

METHODS

We used search terms and Boolean operators to identify studies on the economic burden of diabetes mellitus patients in India between 2015 and 2020. Thereafter, we used the checklists of STROBE, as well as the PRISMA, Drummonds and down, and Black criteria, to assess the quality of included studies. Then, Meta xl was used to calculate the weighted means and weighted proportion based on the quality assessment findings.

RESULTS

Mean expenditure with a maximum weightage of 100% was found in a community-based study, whereas the lowest weightage obtained was 20%. The mean expenditure on diabetes and its complications was calculated as INR 15,535/-(USD 209.3) per year, with a pooled mean of INR 17, 080(USD 230.1)per year. On average, the OPD charges were 3%-5% of the total annual income of the individual. However, when there were complications and hospitalization, the average expenditure was higher (21%) which averages to around 11,000 INR.

CONCLUSIONS

While patients spent 3% of their annual income on only OPD charges on average, complications substantially increased the total cost by more than 10%, which amounts to catastrophic health expenditure.

A Program Evaluation of a Dietary Sodium Reduction Research Consortium of Five Low- and Middle-Income Countries in Latin America

Excess dietary sodium is a global public health priority, particularly in low- and middle-income countries where rates of hypertension and cardiovascular disease are high. The International Development Research Centre funded a research consortium of five Latin American countries (LAC) to inform public health policy for dietary sodium reduction (2016-2020). The objective of this study was to determine the outcomes of this funding on short-term (e.g., research, capacity building) and intermediary outcomes (e.g., policies). A summative program evaluation was conducted, using a logic model and multiple data sources including document review, surveys and interviews. Researchers from Argentina, Costa Rica, Brazil, Peru and Paraguay produced a significant amount of scientific evidence to guide decision making on sodium policy related to its content in foods, consumer behaviors (social marketing), and the health and economic benefits of dietary reduction. A substantive number of knowledge translation products were produced. The funding enabled training opportunities for researchers who developed skills that can be scaled-up to other critical nutrients and health issues. It was unexpected that intermediary policy changes would occur, however several countries demonstrated early policy improvements derived from this research. A funded research consortium of LAC is a practical approach to invoke policy innovations.

Comparative Analysis on Communicable and Non-Communicable Diseases on Catastrophic Spending and Impoverishment in Tanzania

The question of whether communicable or non-communicable diseases have higher economic effects on households is rarely explored from the global to local level despite of their significant contribution in increasing household catastrophic spending and impoverishment. To shed light into this, therefore, this paper comparatively examines the economic effects of communicable and non-communicable diseases in Tanzania by the use of Tanzania Panel Survey data of 2019/2020 which has been used to analyze different parameters to provide needful information. The empirical analysis employed probit, two-stage residual inclusion (2SRI), and control function approachf (CFA) helpful in controlling endogeneity issues. Findings showed that, comparatively, non-communicable diseases have higher economic effects in endangering households into catastrophic spending and impoverishment comparing to communicable diseases. Conclusively, neglecting developing countries to fights against multiplicative effects of these diseases alone will result in killing their economies since most of these countries depend on donors and household as a means of healthcare financing. However, this paper recommends for global initiatives in reducing the burden of disease by funding on palliative care costs and enhancing the availability of affordable health insurance schemes to reduce household economic burden.

Financial risk protection from out-of-pocket health spending in low- and middle-income countries: a scoping review of the literature

Background

Financial risk protection (FRP), defined as households’ access to needed healthcare services without experiencing undue financial hardship, is a critical health systems target, particularly in low- and middle-income countries (LMICs). Given the remarkable growth in FRP literature in recent times, we conducted a scoping review of the literature on FRP from out-of-pocket (OOP) health spending in LMICs. The objective was to review current knowledge, identify evidence gaps and propose future research directions.

Methods

We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines to conduct this scoping review. We systematically searched PubMed, Scopus, ProQuest and Web of Science in July 2021 for literature published since 1 January 2015. We included empirical studies that used nationally representative data from household surveys to measure the incidence of at least one of the following indicators: catastrophic health expenditure (CHE), impoverishment, adoption of strategies to cope with OOP expenses, and forgone care for financial reasons. Our review covered 155 studies and analysed the geographical focus, data sources, methods and analytical rigour of the studies. We also examined the level of FRP by disease categories (all diseases, chronic illnesses, communicable diseases) and the effect of health insurance on FRP.

Results

The extant literature primarily focused on India and China as research settings. Notably, no FRP study was available on chronic illness in any low-income country (LIC) or on communicable diseases in an upper-middle-income country (UMIC). Only one study comprehensively measured FRP by examining all four indicators. Most studies assessed (lack of) FRP as CHE incidence alone (37.4%) or as CHE and impoverishment incidence (39.4%). However, the LMIC literature did not incorporate the recent methodological advances to measure CHE and impoverishment that address the limitations of conventional methods. There were also gaps in utilizing available panel data to determine the length of the lack of FRP (e.g. duration of poverty caused by OOP expenses). The current estimates of FRP varied substantially among the LMICs, with some of the poorest countries in the world experiencing similar or even lower rates of CHE and impoverishment compared with the UMICs. Also, health insurance in LMICs did not consistently offer a higher degree of FRP.

Conclusion

The literature to date is unable to provide a reliable representation of the actual level of protection enjoyed by the LMIC population because of the lack of comprehensive measurement of FRP indicators coupled with the use of dated methodologies. Future research in LMICs should address the shortcomings identified in this review.

Associations between Physical Activity Level and Health Services Use in Spanish Adults

One of the main concerns of governments and organisations worldwide is the cost and burden of health services, with sedentary lifestyles being a significant impacting factor, and physical activity is one of the potential solutions. Therefore, this study aims to analyse the possible associations between the physical activity level, hospitalisation prevalence, and the use and number of visits to emergency services in the Spanish population, examining potential differences between sex and age groups. This is a cross-sectional study based on data from the Spanish National Health Survey 2017 (ENSE 2017), the last one before the COVID-19 pandemic, with 17,199 participants. A descriptive analysis was performed using median and interquartile range (continuous variables) and absolute and relative frequencies (ordinal variables). Intergroup differences were analysed with non-parametric tests: chi-square and z-test for independent proportions (categorical variables), and Kruskal−Wallis and Mann−Whitney U (continuous variables). Spearman’s rho was used to study correlations between variables. A multiple binary regression analysis was performed to predict hospitalisations. Hospitalisations and emergency services use showed a dependence relation with the physical activity level (p < 0.001): those who performed moderate and/or vigorous physical activity used those services less than sedentary individuals and those whose only activity was walking. Thus, associations could be drawn between the hospitalisation prevalence, the use and number of visits to emergency departments, and the physical activity level in the Spanish population aged 18−69 years in the pre-pandemic period.

Costs of multimorbidity: a systematic review and meta-analyses

BACKGROUND

Multimorbidity is a rising global phenomenon, placing strains on countries' population health and finances. This systematic review provides insight into the costs of multimorbidity through addressing the following primary and secondary research questions: What evidence exists on the costs of multimorbidity? How do costs of specific disease combinations vary across countries? How do multimorbidity costs vary across disease combinations? What "cost ingredients" are most commonly included in these multimorbidity studies?

METHODS

We conducted a systematic review (PROSPERO: CRD42020204871) of studies published from January 2010 to January 2022, which reported on costs associated with combinations of at least two specified conditions. Systematic string-based searches were conducted in MEDLINE, The Cochrane Library, SCOPUS, Global Health, Web of Science, and Business Source Complete. We explored the association between costs of multimorbidity and country Gross Domestic Product (GDP) per capita using a linear mixed model with random intercept. Annual mean direct medical costs per capita were pooled in fixed-effects meta-analyses for each of the frequently reported dyads. Costs are reported in 2021 International Dollars (I$).

RESULTS

Fifty-nine studies were included in the review, the majority of which were from high-income countries, particularly the United States. (1) Reported annual costs of multimorbidity per person ranged from I$800 to I$150,000, depending on disease combination, country, cost ingredients, and other study characteristics. (2) Our results further demonstrated that increased country GDP per capita was associated with higher costs of multimorbidity. (3) Meta-analyses of 15 studies showed that on average, dyads which featured Hypertension were among the least expensive to manage, with the most expensive dyads being Respiratory and Mental Health condition (I$36,840), Diabetes and Heart/vascular condition (I$37,090), and Cancer and Mental Health condition in the first year after cancer diagnosis (I$85,820). (4) Most studies reported only direct medical costs, such as costs of hospitalization, outpatient care, emergency care, and drugs.

CONCLUSIONS

Multimorbidity imposes a large economic burden on both the health system and society, most notably for patients with cancer and mental health condition in the first year after cancer diagnosis. Whether the cost of a disease combination is more or less than the additive costs of the component diseases needs to be further explored. Multimorbidity costing studies typically consider only a limited number of disease combinations, and few have been conducted in low- and middle-income countries and Europe. Rigorous and standardized methods of data collection and costing for multimorbidity should be developed to provide more comprehensive and comparable evidence for the costs of multimorbidity.

Catastrophic health expenditure in sub-Saharan Africa: systematic review and meta-analysis

Objective

To estimate the incidence of, and trends in, catastrophic health expenditure in sub-Saharan Africa.

Methods

We systematically reviewed the scientific and grey literature to identify population-based studies on catastrophic health expenditure in sub-Saharan Africa published between 2000 and 2021. We performed a meta-analysis using two definitions of catastrophic health expenditure: 10% of total household expenditure and 40% of household non-food expenditure. The results of individual studies were pooled by pairwise meta-analysis using the random-effects model.

Findings

We identified 111 publications covering a total of 1 040 620 households across 31 sub-Saharan African countries. Overall, the pooled annual incidence of catastrophic health expenditure was 16.5% (95% confidence interval, CI: 12.9-20.4; 50 datapoints; 462 151 households; I ² = 99.9%) for a threshold of 10% of total household expenditure and 8.7% (95% CI: 7.2-10.3; 84 datapoints; 795 355 households; I ² = 99.8%) for a threshold of 40% of household non-food expenditure. Countries in central and southern sub-Saharan Africa had the highest and lowest incidence, respectively. A trend analysis found that, after initially declining in the 2000s, the incidence of catastrophic health expenditure in sub-Saharan Africa increased between 2010 and 2020. The incidence among people affected by specific diseases, such as noncommunicable diseases, HIV/AIDS and tuberculosis, was generally higher.

Conclusion

Although data on catastrophic health expenditure for some countries were sparse, the data available suggest that a non-negligible share of households in sub-Saharan Africa experienced catastrophic expenditure when accessing health-care services. Stronger financial protection measures are needed.

Developing a Complex Understanding of Physical Activity in Cardiometabolic Disease from Low-to-Middle-Income Countries-A Qualitative Systematic Review with Meta-Synthesis

Physical activity behaviour is complex, particularly in low-resource settings, while existing behavioural models of physical activity behaviour are often linear and deterministic. The objective of this review was to (i) synthesise the wide scope of factors that affect physical activity and thereby (ii) underpin the complexity of physical activity in low-resource settings through a qualitative meta-synthesis of studies conducted among patients with cardiometabolic disease living in low-to-middle income countries (LMIC). A total of 41 studies were included from 1200 unique citations (up to 15 March 2021). Using a hybrid form of content analysis, unique factors (n = 208) that inform physical activity were identified, and, through qualitative meta-synthesis, these codes were aggregated into categories (n = 61) and synthesised findings (n = 26). An additional five findings were added through deliberation within the review team. Collectively, the 31 synthesised findings highlight the complexity of physical activity behaviour, and the connectedness between person, social context, healthcare system, and built and natural environment. Existing behavioural and ecological models are inadequate in fully understanding physical activity participation in patients with cardiometabolic disease living in LMIC. Future research, building on complexity science and systems thinking, is needed to identify key mechanisms of action applicable to the local context.
