Background While the non-communicable disease (NCD) burden in the countries of the Gulf Cooperation Council (GCC) (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates) has surged over the past decades, the costs and return on investment (ROI) of implementing cost-effective, WHO-recommended NCD interventions have not been established.
Methods We performed an economic analysis to estimate the ROI from scaling up four sets of NCD interventions over 15 years. We estimated the direct costs of the four main NCDs (cancer, diabetes, cardiovascular diseases and chronic respiratory diseases) using a prevalence-based, bottom-up cost-of-illness approach. We estimated indirect costs based on productivity loss due to absenteeism, presenteeism and premature deaths. We costed the scaling up of interventions using the WHO Costing Tool and assessed the health impact of interventions using the OneHealth Tool. We calculated ROI by comparing productivity and social benefits with the total costs of implementing the interventions.
Results The four main NCDs cost the GCC economy nearly US$50 billion in 2019, equal to 3.3% of its gross domestic product. The indirect costs are estimated at US$20 billion or 40% of the total burden. Implementing the four modelled intervention packages in the six GCC countries over 15 years will cost US$14 billion, with an ROI of US$4.9 for every US$1 invested and significant health and social benefits, including 290 000 averted premature deaths.
Conclusion Based on the results of these six investment cases, we recommend actions to scale up current WHO-recommended cost-effective interventions, strengthen whole-of-government action, drive the NCD legislative agenda, build out the evidence base, generate additional advocacy material, and increase regional collaboration and data-sharing to establish best practices and monitor impact.

WHAT IS ALREADY KNOWN ON THIS TOPIC
Non-communicable diseases (NCDs) pose a significant health and economic burden to societies globally.
Understanding the NCD economic burden and cost-effective action is increasingly important and desired by countries.
A national and regional return-on-investment analysis of NCD interventions was not performed in the Gulf Cooperation Council (GCC) countries.
WHAT THIS STUDY ADDS
The economic burden of NCDs in GCC countries in 2019 is estimated at US$50 billion, or 3.3% of gross domestic product.
Investing in four WHO-recommended NCD intervention packages in the six GCC countries over 15 years will cost US$14 billion.
Return on investment of the interventions is significant and includes 290 000 averted premature deaths and US$4.9 for every US$1 invested over 15 years.
HOW THIS STUDY MIGHT AFFECT RESEARCH, PRACTICE AND/OR POLICY
NCDs impede efforts to strengthen human capital, inclusive of economic growth and health finance in GCC countries.
Implementing WHO-recommended NCD interventions in the GCC countries not only reduces the NCD burden but also provides significant positive return on investment.
There is a need to strengthen whole-of-government action, drive the NCD legislative agenda, build out the evidence base, generate additional advocacy material, and increase regional collaboration and data-sharing to establish best practices and monitor impact.
The prevention and control of non-communicable diseases (NCDs)—principally cancer, diabetes, cardiovascular diseases (CVDs) and chronic respiratory diseases (CRDs)—is the biggest public health challenge for most countries in the world, including those across the Gulf Cooperation Council (GCC). In 2019, 74% of global deaths were due to NCDs, and most Gulf countries surpassed this global average.1 In 2016, 13.1% of the global adult population was obese. On average, the prevalence of obesity in Gulf countries was more than double, and for some countries was nearly triple this.2 In addition to their impact on health, NCDs pose a significant economic burden to the health system, as well as to the wider economy through reduced productivity in the labour market, for example, through employees being absent from work or working at reduced capacity.
Successful approaches to reduce NCD burden are well established. In 2017, WHO3 updated a set of cost-effective interventions, first to prevent and control NCDs by reducing population-level exposure to a common set of NCD risk factors, namely tobacco use, harmful use of alcohol, physical inactivity and unhealthy diet, and second to strengthen the health system response, including the treatment and management of those with NCDs. These interventions remain underimplemented globally, and a key challenge is making the economic argument for their implementation.
While estimates for the global economic burden of NCDs and return on investment (ROI) of a core set of NCD interventions have been developed in the past,4 countries are increasingly looking to understand the detailed impact of NCDs on their own economies as well as the ROI from implementing interventions to prevent and control NCDs. While there is a wealth of information on NCDs and the cost-effective interventions to address them,5 there is a lack of research comparing the NCD intervention benefits within and across countries, including those in the Gulf region.
The aims of this study were: (1) to estimate the overall economic burden from NCDs in the six countries in the GCC: Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates (UAE); (2) to determine the cost of scaling up a set of WHO-recommended interventions for the prevention and control of NCDs in each country2; and (3) to quantify the ROI from these interventions over 15 years. This study adds to the growing body of research on investments in NCD prevention and control, and addresses the need for more comparative analyses of NCD intervention benefits across regions of concern.
Study design and scope
Investment cases were generated for each of the six countries to support governments gaining political traction to prioritise investments in NCD prevention and control.6
National data were complemented by relevant regional and international proxy data where no national data were available. Population figures were obtained from local reports and the World Bank database.7 Morbidity and mortality data were obtained from local literature, STEPwise Approach to NCD Risk Factor Surveillance Survey,8 and estimates from the Institute for Health Metrics and Evaluation.9 Health expenditure data were collected from local reports published by Ministries of Health, the WHO Global Health Expenditure database10–12 and the World Bank database.13 Labour force data were collected from the World Bank database14–17 and local literature (online supplemental material).
The economic burden
The economic burden of NCDs was estimated by combining direct and indirect costs. Direct costs were considered as costs incurred by individuals and the health system to treat the four main NCDs: cancer, diabetes, CVDs and CRDs. Indirect costs were considered as the economic loss in the labour market from premature death for the four main NCDs, as well as time off from work (absenteeism), and work at reduced capacity (presenteeism) due to CVDs and diabetes. An Excel file was developed to calculate the economic burden in each country.
Direct costs include medical staff salaries, procedures and treatment. This study followed the prevalence-based, bottom-up cost-of-illness approach to estimate the direct cost of NCDs. The total health expenditure on each of the four NCDs was calculated by multiplying the estimated average cost per patient by the estimated number of patients using the health services. The epidemiological data used to estimate the number of patients using the health services for NCDs were extracted from Bahrain Ministry of Health Statistics report 2018,18 Bahrain Health Information System I-Seha,19 Kuwait Ministry of Health annual health report 2016,20 Oman Ministry of Health statistics report 2018,21 Saudi Arabia World Health Survey 2019,22 Saudi Arabia Household Health Survey 201723 and local literature.24 In the absence of local data or literature, national data were complemented by Institute for Health Metrics and Evaluation country profile.9 In the UAE, the number of patients using the health services was estimated by the UAE Ministry of Health and Prevention (MOHAP) based on the proportion of population using the services in the three insurance schemes in 2019 and adjusted for rest of the Emirates (UAE).25
The average medical cost per patient for each NCD was estimated based on local, regional and international literature. The annual average cost of diabetes treatment was estimated based on a study done in Bahrain26 in year 2015 and we adjusted it to year 2018 price using Bahrain consumer price index. Bahrain-adjusted estimation was used as a proxy for Kuwait, Oman, Qatar and Saudi Arabia. The annual average cost of CVDs treatment was estimated based on a local study done by the Bahrain Defense Force Hospital27 in 2016. Bahrain estimation was used as a proxy for Kuwait, Oman and Qatar. The cost of CVDs treatment in Saudi Arabia was based on a study done in Saudi Arabia and published in 2019.28 The annual average cost of cancer treatment for Bahrain and Kuwait was estimated based on a local study done by the Bahrain Defense Force Hospital27 in 2016. The cost for Oman and Saudi Arabia was based on estimation done by Oman National Oncology Centre of the Ministry of Health29 in 2015. The cost for Qatar was based on estimation done by Qatar Cancer Society 30 in 2018. The annual average cost of CRDs treatment was based on a study done in the USA31 in 2010. We adjusted the figures to year 2018 price using the USA consumer price index. The USA-adjusted estimation was used as a proxy for Kuwait, Oman, Qatar and Saudi Arabia. The average cost per patient in UAE for the four diseases in 2019 was estimated by the UAE MOHAP based on three tightly identified insurance schemes.25 Once the estimations and calculation were done for each country, a committee from the Ministry of Health reviewed these estimations and approved them (more details are available in online supplemental material).
These were estimated as follows. First, the number of people of working age (15–60 years) with NCDs in each country was estimated. The size of the working-age population with NCDs was then multiplied by the rate of participation in the labour force and employment to determine the prevalence of NCDs in workers. Similarly, the number of deaths from NCDs was multiplied by the rate of participation in the labour force and employment to estimate the number of workers who died from NCDs. The number of deaths was subtracted from the number of workers with prevalent NCDs to estimate the number of workers who survived despite their illness. The rate of reduction in productivity due to absenteeism,13 32 presenteeism26 33 and labour force participation rate reduction34 because of NCDs was multiplied by the number of surviving workers to estimate the total number of unproductive days that resulted from NCDs. Gross domestic product (GDP) per worker was then used to approximate each worker’s productive output in the year 2019 with GDP per worker multiplied by the total number of unproductive working days. Values from previous studies13 26 32–34 were used to calculate the percentage decrease in productivity due to absenteeism and presenteeism, and the reduction in labour force participation rate because of NCDs (online supplemental material).
The loss of GDP due to premature death of workers was estimated using the human capital approach. This assumes that forgone economic output is equivalent to the total output that would have been generated by workers through their life until reaching retirement age. In this method, all future potential income lost by a worker who dies during his or her working lifetime is calculated from the number of working years lost between the age at death and the age at which the deceased employee would have reached the average retirement age. Productivity losses due to premature deaths were calculated as the product of the total working years lost in all age groups multiplied by the labour force participation rate, age-specific employment rate and GDP per worker.
Return on investment
Based on the WHO ‘best buys’ and recommended interventions for the prevention and control of NCDs, four policy and clinical intervention packages were included in the analysis.3 They were: (1) a tobacco control package; (2) a physical activity awareness package; (3) a salt reduction package; and (4) primary care-level clinical interventions to screen and treat CVDs and diabetes. The time frame for implementing these interventions was 15 years. The model employed a front-growth scale-up scenario for policy interventions. This pattern assumed that much of the capacity to scale up policy interventions was already in place, meaning that coverage can escalate rapidly, within 2 years. For clinical interventions, the model employed a linear scale-up. This pattern assumed a gradual but sustained increase in coverage, aiming to reach 80% coverage within 15 years. Intervention-specific data on current effective coverage of clinical interventions are not available. The current effective coverage was estimated to be 5% in line with previous WHO analyses in the area of NCDs35 and validated with focal persons from the Ministry of Health in each country (online supplemental material).
Costs of interventions
Costs of intervention packages were calculated using the WHO Costing Tool for NCD prevention and control,36 which costs human resources, training, external meetings, mass media campaigns, and miscellaneous equipment needed to enact the tobacco, salt and physical activity awareness packages. Each policy intervention contains assumptions, set by WHO experts, about the quantity of inputs required to implement and enforce it. The WHO Costing Tool estimates the quantity of resources needed at the national, regional and district levels. For clinical interventions, the WHO Costing Tool estimates costs of treatment interventions, primary care visits, ancillary care visits, laboratory and diagnostic tests, and drugs for the total number of NCD cases that are expected to be covered each year. To estimate the total cost of interventions as a percentage of total health expenditure (THE) over 15 years, the 2019 THE in each country was multiplied by 15 years and discounted at a rate of 3%.
Estimating the impact of interventions
The WHO OneHealth Tool37 was used to assess the health benefits of implementing and scaling up policy and clinical interventions by modelling the number of disease cases averted, lives saved and healthy life-years gained over the 15 years under study. We used the default impact sizes of the interventions and default relative risks that are inserted into the OneHealth Tool based on WHO best available evidence.38 39 The healthy years lived (HYL) is the number of remaining years that a person of a certain age is still supposed to live without disability. In the OneHealth Tool, HYL at time t are estimated as follows: HYL (t,s)=P(t,s)×(1−DW(t,s)). Where P(t,S) is the prevalence of state S at time t and DW(t,S) is the disability weight associated with state S at time t. Description of the model used and assumptions are available elsewhere40 (more details are available in online supplemental material). The same scale-up patterns used for the cost of the policy and clinical intervention were used for modelling the impact and benefits. The productivity benefits were calculated by adding the value of avoided presenteeism, the value of avoided absenteeism and the value of avoided premature mortality, using the GDP per worker in 2019 as a proxy for each worker’s productive output. Treatment costs prevented were not included in the benefits analysis. The social benefits were calculated by applying a value of 0.5 times GDP per capita to each healthy life-year gained from the interventions.41
Calculating the ROI
The ROI for each intervention package was reached by comparing the productivity and social benefits with the total costs of setting up and implementing the interventions. The model employed a 3% discount rate to arrive at the net present value of all costs and economic benefits. The ROI analysis was based on a spreadsheet model developed by WHO.
Economic and health burden of NCDs
The investment cases found that in 2019, across the six GCC countries, nearly 43 000 people died due to the four major NCDs (cancer, diabetes, CVDs and CRDs), accounting for roughly 46% of all deaths in the region, ranging from 41% of all deaths in Saudi Arabia and 65% of all deaths in Kuwait. Of these deaths, nearly 32 000 people died due to CVDs, equivalent to 75% of the deaths due to the four major NCDs and 34% of all deaths in the region. The cost to the GCC economy from these four NCDs was nearly US$50 billion, equivalent to 3% of the GCC’s 2019 GDP. The average economic burden in each country as a share of its GDP in 2019 was 3.3%, ranging from 2.7% of GDP in the UAE and Qatar to 3.9% of GDP in Kuwait.
The direct costs were estimated at US$30 billion, accounting for 60% of the total economic burden. Direct costs of treating the four NCDs constituted 36.5% of GCC total health expenditure. The indirect costs were estimated at US$20 billion, accounting for 40% of the total economic burden.
The average economic burden due to direct costs in each country as a share of its GDP in 2019 is 1.8%, ranging from 1.1% of GDP in Qatar to 2.2% of GDP in Saudi Arabia. The average economic burden due to indirect costs in each country as a share of its GDP in 2019 was 1.5%, ranging from 0.9% of GDP in Saudi Arabia to 1.9% of GDP in Kuwait. Table 1 depicts direct and indirect costs due to NCDs for the six countries.
Cost of interventions
The total cost of implementing the four intervention packages over 15 years in the six GCC countries was estimated at US$14 billion. Table 2 presents these costs for each country, including the share by which each country would need to increase its THE to implement all intervention packages.
On average, countries would need to increase THE by 1.4% over 15 years, ranging from 1.2% in Saudi Arabia to 4.6% in Bahrain. Implementing all interventions over 15 years would cost an average of US$243 per capita (US$16 per capita per year), ranging from US$149 per capita in Oman to US$584 in Bahrain. Of note, the package of CVD and diabetes clinical interventions cost the most at US$12.4 per capita per year, while implementing only the population-based measures decreases cost per capita to US$3.8 per year.
Implementing intervention packages at the recommended scale-up would avert more than 290 000 premature deaths and add nearly 2 million healthy life-years to the population in the GCC over the next 15 years. Their implementation would also prevent more than 266 000 stroke events and more than 207 000 ischaemic heart disease events over the next 15 years. The number of lives saved ranges from 13 479 in Bahrain to 191 713 in Saudi Arabia (table 3).
Beyond fostering healthier societies, investing in NCDs brings economic benefits. The recovered economic output from implementing the recommended intervention packages was estimated to be US$49 billion in labour productivity gains over the 15 years, equivalent to 3% of the GCC’s 2019 GDP. The social benefits resulting from healthy life-years gained over the 15 years was estimated at US$19.5 billion. Adding the social value to the recovered economic output results in economic benefits of US$68.5 billion over the 15-year period (equivalent to US$1200 per capita over the 15 years, or US$80 per capita per year). Differences in benefits between countries are primarily due to economic measures of GDP per employed person and labour force participation rates.
Comparing costs and benefits showed that, on average, interventions had ROI over 15 years that was greater than US$4.9 for each US$1 invested now (ROI=493%). Figure 1 depicts the costs and benefits over 15 years by country, with costs per capita ranging from US$149 in Oman to US$584 in Bahrain. The average cost across the region per year per capita to implement all intervention packages was US$16, while the average benefits per year per capita amounted to US$80. Table 4 depicts the ROI of each intervention package for each country, with the tobacco control and salt reduction packages providing the highest ROI among all intervention packages.
To our knowledge, this is the first study that estimated the economic and health burden of NCDs, as well as the ROI of scaling up WHO-recommended interventions for the prevention and control of NCDs in the six countries of the GCC. The findings indicate that four major NCDs cost the GCC economy around 3.3% of GDP every year, and account for over 45% of GCC country THE, impeding the GCC’s efforts to increase efficiency in the health sector and to achieve fiscal balance. Rising prevalence trends in GCC countries of the major NCDs examined imply that the challenge will only become more difficult with time.
The investment cases also show that investing in four proven and cost-effective intervention packages (best buys) would avert US$49 billion over 15 years and 290 000 premature deaths. The ROI is high, averaging US$4.9 over 15 years for every US$1 invested now. Thus, the best buys can increase people’s life expectancy and quality of life while decreasing the burden on the national economy and accelerating economic growth.
The burden of NCDs in the GCC countries
While similar studies were focused on low/middle-income countries (LMICs),42 43 relatively few studies have estimated the health and economic burden of NCDs in GCC countries, and fewer still have drawn comparisons between GCC countries. Our study expands on the most comprehensive studies to date on the burden of NCDs in GCC countries,44 by using national data for morbidity, mortality and cost of treatment data where possible, and other data from other GCC countries as proxies where necessary (Finkelstein et al use international estimates only).9 45 Finkelstein et al44 found diabetes to contribute the most to the NCD burden, while our study finds CVDs to be the largest contributor. This is likely due to the aforementioned differences in data sources, in addition to our study’s inclusion of premature death into the burden calculation. Finkelstein et al’s estimates for per-patient costs and productivity reductions for diabetes are higher than ours46 47; we believe lower productivity reduction estimates for diabetes and higher per CVD patient costs used under our study to be more defensible.
Other relevant studies were conducted in Saudi Arabia. In 2017, WHO estimated the economic burden due to NCDs in Saudi Arabia to be US$18.6 billion annually with direct costs accounting for 30% of the burden.48 Our analysis estimated the economic burden in Saudi Arabia to be US$24.4 billion every year with direct costs accounting for 45% of the burden. These differences in results are likely explained by the increased prevalence of NCDs and the availability of more accurate cost per patient data in our study.
Globally, the most methodologically comparable studies conducted to date are 18 NCD investment cases completed under the WHO-United Nations Development Programme joint programme on catalysing multisectoral action for NCDs, coordinated under the United Nations Interagency Task Force on NCDs (UNIATF).49 Most notably, the GCC countries face higher direct costs than in other countries, accounting for 60% of the burden compared with 16% on average across other countries. This is likely due to higher costs of treatment, NCD prevalence and treatment coverage rates in GCC countries than in the other countries examined. All other investment cases are among LMICs where expensive treatment options are less available and THE is overall lower, and consumption of healthcare is lower.
Comparing the six investment case findings with each other, differences between GCC countries are driven mainly by differences in GDP per employed person, labour force participation rates, prevalence of NCDs and mortality rates, prices difference of healthcare and implementation costs for the modelled interventions.
ROI of NCD interventions in the GCC countries
The NCD investment cases indicate that the costs required to fully scale WHO-recommended NCD policy and clinical interventions are relatively low. Differences in implementation costs between GCC countries are likely due to differences in costs of healthcare service provision—especially for clinical interventions which are more costly—and population size, as countries with larger populations have a lower per-person cost for the population-based measures due to the economy of scale. To illustrate, the package of CVD and diabetes clinical interventions cost the most at US$12.4 per capita per year while implementing only the population-based measures decreases cost per capita to US$3.8 per year.
Among all intervention packages, the salt reduction measures had by far the highest ROI. This is due primarily to salt reduction’s high effectiveness at reducing high blood pressure and hence CVD prevalence. The package of clinical interventions has lower ROI due to their high costs of implementation. Importantly, however, while constituting the most expensive package, our findings indicate that the CVD and diabetes interventions have the greatest potential to avoid premature mortality and morbidity; thus, they are necessary to support the population’s right to health. Differences in ROI between countries are likely driven mainly by implementation costs and population size, as well as economic measures of GDP per employed person and labour force participation rates.
The investment case methodology used has several limitations. Our study does not include all NCDs and does not capture all productivity losses associated with NCD morbidity and mortality such as unpaid productivity. This is due mostly to limitations of the model, which focuses on the four major NCD categories and productivity losses at the workplace since these are simpler to estimate. Furthermore, the model calculates productivity losses from absenteeism and presenteeism associated with CVDs and diabetes only, as there are no available parameters for reductions in productivity due to cancer and CRD in the region and limited information globally. Besides healthcare treatment costs, the investment case model does not estimate other direct costs associated with NCDs such as non-medical costs (eg, transport to a health provider), retirement benefits and disability payments, in addition to intangible costs such as care provided by relatives and quality of life. There were no available data in each country to estimate the average medical costs per patient and we had to use international data to estimate the direct costs. Some of these data were not recent data. Adjustments were done using consumer price index. There were no available data in each country to estimate the baseline effective coverage of the clinical interventions. The suggested35 assumption of 5% is one of the limitations. However, we used the same coverage scale-up pattern for estimating the cost and for estimating the benefits. Once the estimations and calculation were done for each country, a committee from the Ministry of Health reviewed these estimations and approved them. We included detailed description of the estimations and adjustments in the online supplemental materials.
We used the GDP per worker as a proxy for each worker’s productive output. It is important for the reader to note that the main economic driver in GCC countries is hydrocarbon and natural resources, and we included the GDP of hydrocarbon in the estimation of GDP per employment.
On the benefits side, the model does not estimate reductions in direct healthcare costs to treat NCDs, nor does it estimate the benefits from reductions in presenteeism and absenteeism associated with reductions in cancer and CRD prevalence. Moreover, the calculated returns only include the economic benefits of improved health outcomes and do not account for the significant additional revenue that would come from the recommended increases in excise tax rates on health-harming products including tobacco and alcohol. Combined, these limitations imply that the model is conservative in its estimates and that both the burden of NCDs as well as the benefits of investing in NCD prevention and control are higher than estimated.
Finally, data collection relied heavily on project countries’ abilities to provide national data for NCD prevalence and mortality, as well as intervention coverage and cost estimates. The model employed regional and international estimates where countries were not able to collect national data or national data presented gaps. Data triangulation from different sources was used to improve the accuracy of the model.
Recommendations for strengthening NCD prevention and control among GCC countries
The analysis indicates that among the four NCD categories examined, CVDs account for the largest share of premature mortality, morbidity and economic losses each year, followed by diabetes. This study confirms the high cost of treating these conditions and the much lower cost of preventing them. Investing in preventing diabetes and CVDs is both cost-effective and ultimately increases the sustainability of the health sector. The GCC countries should therefore invest in measures to promote healthy diets and physical activity; detect, diagnose and treat NCDs early; and reduce consumption of health-harming products.
GCC countries have already made considerable progress in advancing the prevention and control of NCDs, and several have received WHO and UNIATF awards for progress and leadership in combating NCDs and advancing health. Most GCC countries have multisectoral NCD coordination mechanisms, ambitious NCD strategies and targeted programmes and initiatives to drive NCD prevention and control. However, in practice, key challenges remain, particularly around efficient and lasting engagement of non-health stakeholders, slow legislative action and insufficient evidence due to the absence of standardised NCD surveillance systems.
Used as advocacy tools to demonstrate the substantial health and economic gains of investing in NCD action, the six GCC NCD investment cases can help engage non-health stakeholders, gather high-level support and enhance regional collaboration. GCC countries and relevant United Nations bodies should now consider establishing a multiyear plan to invest in scaling up the WHO-recommended cost-effective interventions; strengthen national multisectoral coordination, planning and strategy; pass strong NCD legislation; increase regional collaboration and data-sharing to establish best practices and monitor impact; expand efforts to monitor the entire population for NCDs and their risk factors; and implement novel policy approaches and test innovative solutions to increase utilisation of existing services and incentivise healthy behaviour. This would not only benefit GCC countries, as they could serve as a model of successful investment in NCD prevention and control in the rest of the region and beyond.
Finally, addressing the social, economic and environmental determinants of health which lay outside the health sector’s purview requires investments beyond the ones modelled under the NCD investment cases. In GCC countries, given that most of the people live in urban areas and are insufficiently physically active, purposeful urban planning is required to incentivise healthy behaviour. Investments in food systems are required to improve access and availability of healthy foods; fiscal policies can also have a strong impact on shaping the food environment and consumer choice and should be considered. Taxes on health-harming products not only have the potential to prevent harm but also to generate enough revenue to fully scale the NCD measures modelled under the investment cases.
This is the only study to our knowledge that examines ROI of cost-effective interventions to address NCDs in GCC countries. It also estimates the social and economic burden of NCDs in the GCC countries using national prevalence and treatment cost data, and by examining productivity losses in greater detail across a wider range of NCDs than previous studies. The large NCD burden indicates the need to comprehensively address the main risk factors that contribute to NCDs. This study also shows that WHO-recommended interventions are highly cost-effective at reducing the burden of NCDs.
Based on the results of these six investment cases, we recommend actions to scale up current WHO-recommended cost-effective interventions, strengthen whole-of-government action, drive the NCD legislative agenda, build out the evidence base, generate additional advocacy material, and increase regional collaboration and data-sharing to establish best practices and monitor impact.
