ABSTRACT

OBJECTIVE

To update the estimated cost of physical inactivity for the Brazilian Unified Health System (SUS).

METHODS

The hospitalization costs were accessed via a database of the Ministry of Health – Informatics Department of the Brazilian SUS. Physical inactivity for the year 2017 was accessed via the Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (Vigitel – Surveillance System for Risk and Protective Factors for Chronic Diseases by Telephone Survey). Seven chronic non-communicable diseases (NCD) were selected via the international classification of disease (ICD-10). The population fraction attributable to physical inactivity was calculated based on relative risk reported in previous studies and the prevalence of physical inactivity.

RESULTS

In 2017, the seven NCD considered in the analysis were responsible for 154,017 hospital admissions in adults older than 40 years old, residing in the state capitals and the Federal District, which corresponded to 6.5% of hospitalizations and 10.6% of SUS costs at an estimated US$ 112,524,914.47. Considering the group of individuals with insufficient physical activity in their leisure time, the percentage cost attributed to physical inactivity reached 17.4% of the estimated costs with NCD. At a national level, NCD were responsible for approximately 740 thousand hospitalizations, costing US$ 482 million, from which 17.4%, US$ 83 million were attributed to physical inactivity.

CONCLUSION

This study provides evidence to conclude that physical inactivity exerts an economic impact on the SUS due to NCD hospitalization. Physical inactivity is a modifiable lifestyle and compelling evidence, including that of this article, supports the promotion of a more active community as one of the major targets of public health care policies.

INTRODUCTION

Physical inactivity has been considered a global burden to the health care system¹1. World Health Organization. World health statistics 2018: monitoring health for the SDGs, sustainable development goals. Geneva: World Health Organization; 2018. , ²2. World Health Organization. Global action plan on physical activity 2018–2030: more active people for a healthier world. Geneva: World Health Organization; 2018. . It is related to the increased risk for cardiovascular and metabolic diseases (i.e.; diabetes and hypertension)³3. Lavie CJ, Ozemek C, Carbone S, Katzmarzyk PT, Blair SN. Sedentary Behavior, Exercise, and Cardiovascular Health. Circ Res. 2019 Mar;124(5):799-815. https://doi.org/10.1161/CIRCRESAHA.118.312669

https://doi.org/10.1007/s10654-018-0380-... . Furthermore, physical inactivity is responsible for 6% of deaths and is the fourth risk factor for mortality globally; behind hypertension (13%), tobacco use (9%), and high blood glucose (6%)⁵5. World Health Organization. Global health risks: mortality and burden of disease attributable to selected major risks. Geneva, World Health Organization; 2009. . In an opposite direction, regular physical activity is related to decreased risk of morbidity and mortality and better quality of life⁶6. Lear SA, Hu W, Rangarajan S, Gasevic D, Leong D, Iqbal R, et al. The effect of physical activity on mortality and cardiovascular disease in 130 000 people from 17 high-income, middle-income, and low-income countries: the PURE study.

https://doi.org/10.1016/S0140-6736(17)31... . Furthermore, eliminating the population’s physical inactivity leads to an estimated life expectance gain from 0.49 to 1.25 years for all ages over 40 years old⁷7.

About 23% of the world’s adult population and 81% of the world’s adolescent population do not reach the recommended levels of regular physical activity for maintaining health⁸8. Guthold R, Stevens GA, Riley LM, Bull FC. Worldwide trends in insufficient physical activity from 2001 to 2016: a pooled analysis of 358 population-based surveys with 1·9 million participants. Lancet Glob Health. 2018 Oct;6(10):e1077-86. https://doi.org/10.1016/S2214-109X(18)30357-7
https://doi.org/10.1016/S2214-109X(18)30... . In Latin America and the Caribbean, 39.1% of the population is physically inactive. Among those, Brazil has the highest prevalence of physical inactivity, with 47% of the population not reaching recommended levels of physical activity⁸8. Guthold R, Stevens GA, Riley LM, Bull FC. Worldwide trends in insufficient physical activity from 2001 to 2016: a pooled analysis of 358 population-based surveys with 1·9 million participants.

https://doi.org/10.1016/S2214-109X(18)30... .

Additionally to the social costs¹¹11. Warburton DE, Nicol CW, Bredin SS. Health benefits of physical activity: the evidence. CMAJ. 2006 Mar;174(6):801-9. https://doi.org/10.1503/cmaj.051351
https://doi.org/10.1503/cmaj.051351... , physical inactivity economically burdens the health care system. Conservative estimates revealed that physical inactivity represented a US$ 53.8 billion cost for health care systems worldwide¹²12. Ding D, Kolbe-Alexander T, Nguyen B, Katzmarzyk PT, Pratt M, Lawson KD. The economic burden of physical inactivity: a systematic review and critical appraisal. Br J Sports Med. 2017 Oct;51(19):1392-409. https://doi.org/10.1136/bjsports-2016-097385
https://doi.org/10.1136/bjsports-2016-09... . Of this cost, US$ 2 billion was paid by the public sector, US$ 12.9 billion was paid by the private sector, and US$ 9.7 billion was paid by the families. Likewise, the deaths related to physical inactivity contributed to US$ 13.7 billion in productivity losses¹²12. Ding D, Kolbe-Alexander T, Nguyen B, Katzmarzyk PT, Pratt M, Lawson KD. The economic burden of physical inactivity: a systematic review and critical appraisal. Br J Sports Med. 2017 Oct;51(19):1392-409. https://doi.org/10.1136/bjsports-2016-097385
https://doi.org/10.1136/bjsports-2016-09... .

In 2013, 15% of the hospital admissions were estimated to be due to physical inactivity with a projected cost of US$ 732,586,706 to the public healthcare system in Brazil¹³13. Bielemann RM, Silva BG, Coll CV, Xavier MO, Silva SG. Burden of physical inactivity and hospitalization costs due to chronic diseases. Rev Saude Publica. 2015;49(0):1-8. https://doi.org/10.1590/S0034-8910.2015049005650
https://doi.org/10.1590/S0034-8910.20150... . Considering that Brazil maintained a high prevalence of physical inactivity in the population, we sought to update the estimated economic impact of physical inactivity on the Brazilian Unified Health System (SUS), which provides 80% of hospital care in Brazil. Furthermore, the knowledge about the financial burden of physical inactivity will strengthen the importance to educate the population about having a more active lifestyle. Those results will show that public policy actions must be taken by the policymakers and stakeholders to promote a lifestyle change at the populational levels. Furthermore, acknowledging the estimated financial costs of physical inactivity can support the financial management of the SUS.

Therefore, the estimated economic impact of physical inactivity was found by analyzing the cost of hospitalization due to non-communicable diseases (NCD) attributable to three levels of physical inactivity in the SUS.

METHODS

This is a descriptive study based on secondary data. Seven chronic NCD were selected ( Table 1 ) according to the international classification of disease (ICD-10), which have a decreased risk with increased physical activity⁴4. Patterson R, McNamara E, Tainio M, Sá TH, Smith AD, Sharp SJ, et al. Sedentary behaviour and risk of all-cause, cardiovascular and cancer mortality, and incident type 2 diabetes: a systematic review and dose response meta-analysis.

https://doi.org/10.1016/S0140-6736(17)31... , ⁷7. Lee IM, Shiroma EJ, Lobelo F, Puska P, Blair SN, Katzmarzyk PTp. Effect of physical inactivity on major non-communicable diseases worldwide: an analysis of burden of disease and life expectancy. Lancet. 2012 Jul;380(9838):219-29. https://doi.org/10.1016/S0140-6736(12)61031-9
https://doi.org/10.1016/S0140-6736(12)61... . The hospitalization costs were accessed via a database of the Ministry of Health – Departamento de Informática do Sistema Único de Saúde do Brasil (Datasus – Informatics Department of the Brazilian Unified Health System). The Datasus is a body of the Executive Secretariat of the Ministry of Health, whose mission is to use information technology modernization to support the Brazilian SUS. The prevalence of physical inactivity in the year 2017 was accessed via the Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (Vigitel – Surveillance System for Risk and Protective Factors for Chronic Diseases by Telephone Survey), which is maintained by the Ministry of Health. The Vigitel is a telephone survey sampled from the telephone lines register. Individuals from different sociodemographic levels have different probabilities of being interviewed. Thus, Vigitel assigns a weight to each observation, which was used in our study to make statistical inferences for the population of each Brazilian State capital.

The prevalence of physical inactivity among Brazilians was calculated via Vigitel microdata for the year 2017 and was based on data on physical inactivity in the 26 state capitals and the Federal District ( Table 2 ). The Ministry of Health adopted three indicators of physical inactivity for the Vigitel: a) Inactive or sedentary adults were the subjects who did not practice any physical activity during their leisure time for the last three months, do not engage in intense physical efforts at work, do not use active commute (e.g., walking or cycling) for work or school for a minimum of 20 minutes and do not participate in heavy house cleaning; b) Individuals with an insufficient practice of physical activity are those whose time spent in physical activities, including commuting to work and active jobs, does not reach 150 minutes of moderate-intensity physical activities per week, or 75 minutes of vigorous-intensity activities per week; c) Adults with an insufficient practice of physical activity during their leisure time are those whose practice of moderated intensity physical activity during leisure time does not reach 150 minutes per week, or at least 75 minutes of vigorous physical activity a week.

We used the relative risk (RR) of physical inactivity reported in Lee et al.⁷7. Lee IM, Shiroma EJ, Lobelo F, Puska P, Blair SN, Katzmarzyk PTp. Effect of physical inactivity on major non-communicable diseases worldwide: an analysis of burden of disease and life expectancy.

https://doi.org/10.1016/S0140-6736(12)61... and Bielemann et al.¹³13. Bielemann RM, Silva BG, Coll CV, Xavier MO, Silva SG. Burden of physical inactivity and hospitalization costs due to chronic diseases. Rev Saude Publica. 2015;49(0):1-8. https://doi.org/10.1590/S0034-8910.2015049005650
https://doi.org/10.1590/S0034-8910.20150... to calculate the fraction of the costs for Brazilian SUS that is attributable to physical inactivity (population attributable fraction – PAF)⁷7. Lee IM, Shiroma EJ, Lobelo F, Puska P, Blair SN, Katzmarzyk PTp. Effect of physical inactivity on major non-communicable diseases worldwide: an analysis of burden of disease and life expectancy. Lancet. 2012 Jul;380(9838):219-29. https://doi.org/10.1016/S0140-6736(12)61031-9
https://doi.org/10.1016/S0140-6736(12)61... , ¹³13. Bielemann RM, Silva BG, Coll CV, Xavier MO, Silva SG. Burden of physical inactivity and hospitalization costs due to chronic diseases. Rev Saude Publica. 2015;49(0):1-8. https://doi.org/10.1590/S0034-8910.2015049005650
https://doi.org/10.1590/S0034-8910.20150...

Where p is the prevalence of physical inactivity and RR is the relative risk associated with physical inactivity.

The RR and PAF were attributed to the population over 40 years old ( Table 3 ). The analysis was stratified by gender and grouped by geographic region⁷7. Lee IM, Shiroma EJ, Lobelo F, Puska P, Blair SN, Katzmarzyk PTp. Effect of physical inactivity on major non-communicable diseases worldwide: an analysis of burden of disease and life expectancy. Lancet. 2012 Jul;380(9838):219-29. https://doi.org/10.1016/S0140-6736(12)61031-9
https://doi.org/10.1016/S0140-6736(12)61... , ¹³13. Bielemann RM, Silva BG, Coll CV, Xavier MO, Silva SG. Burden of physical inactivity and hospitalization costs due to chronic diseases. Rev Saude Publica. 2015;49(0):1-8. https://doi.org/10.1590/S0034-8910.2015049005650
https://doi.org/10.1590/S0034-8910.20150... considering the three indicators of physical inactivity separately. To estimate the impact of physical inactivity on hospitalization costs, the PAF was multiplied by the total cost of hospitalizations caused by each of the seven NCD.

Since the data on physical inactivity used are representative of residents of state capitals and the Federal District, data related to hospitalizations was filtered to include only those corresponding to patients residing in the city capitals. The hospitalization cost was pooled from the Datasus database, corresponding to patients residing in the 26 state capitals and the Federal District. The cost of each disease and the total cost of hospitalizations and the total cost per hospitalization financed by the SUS were then calculated, according to the ICD 10 code of the main cause of the hospitalization diagnosis. We performed the same calculation by differentiating the city’s location region.

Finally, based on the percentages of incidence of hospitalization costs from NCD attributable to physical inactivity on the total hospitalization costs of the SUS in the state capitals and the Federal District, the incidence of those costs was extrapolated for the national level. Therefore, the simulation assumed that the physical inactivity level data observed in the state capitals would be representative of the whole State. The currency conversion value to convert Brazilian “reais” to United States dollars was 3.192 “reais” to 1 dollar.

All estimates were made using the statistical software R (packages used: survey, dplyr and lubridate).

RESULTS

In 2017, the seven NCD considered in the analysis were responsible for 154,017 hospital admissions in adults older than 40 years old, living in the state capitals and Federal District. The NCD corresponded to 6.5% of all hospitalizations and 10.6% of SUS costs in 2017, at an estimated cost of US$ 112,524,914.47 ( Table 4 ). Of this total, US$ 56,491,734.96 was associated with the cost of hospitalizations for male patients, mostly associated with ischemic heart disease (US$ 38,604,338.97), whereas hospitalizations for female patients cost US$ 56,033,179.51 of which US$ 25,555,573.62 were due to ischemic heart disease and US$ 12,000,941.73 to breast cancer. Ischemic heart disease (6.05%), cerebrovascular diseases (2.08%) and breast cancer (10.7%) caused the higher costs of hospitalizations among the NCD.

Since we estimated the burden of NCD at the national level and not only for the 26 state capitals and Federal District, we can say that NCD were responsible for approximately 740 thousand hospitalizations in 2017 ( Table 4 ), costing US$ 482 million. The percentage of this cost attributed to physical inactivity, considering the more comprehensive cut of individuals with insufficient physical activity in their leisure time, reached 17.4% of the estimated NCD costs, totaling US$ 83.9 million in 2017. Using the most recent data available by Datasus, the estimates were updated for the year 2019 ( Table 5 ). Therefore, NCD were responsible for a total of approximately 786 thousand hospitalizations, producing a total cost of US$ 526 million. The percentage of this cost attributed to physical inactivity, considering the most comprehensive cut of individuals with insufficient physical activity in their leisure time, reached US$ 91.4 million.

DISCUSSION

This study updates the cost of physical inactivity for the SUS in Brazil. Furthermore, our estimates considered three levels of physical inactivity. A plethora of scientific investigations provided compelling evidence about the burden of physical inactivity worldwide, and the urgent need to change the population’s behavior to a more active one²2. World Health Organization. Global action plan on physical activity 2018–2030: more active people for a healthier world. Geneva: World Health Organization; 2018. . About half of the Brazilian population does not reach the recommended physical activity levels, and is more susceptible to developing NCD⁸8. Guthold R, Stevens GA, Riley LM, Bull FC. Worldwide trends in insufficient physical activity from 2001 to 2016: a pooled analysis of 358 population-based surveys with 1·9 million participants. Lancet Glob Health. 2018 Oct;6(10):e1077-86. https://doi.org/10.1016/S2214-109X(18)30357-7
https://doi.org/10.1016/S2214-109X(18)30... .

Worldwide, physical inactivity levels vary considerably between countries depending on geography, educational status, economic levels, and social status, which leads to large differences between subpopulations⁸8. Guthold R, Stevens GA, Riley LM, Bull FC. Worldwide trends in insufficient physical activity from 2001 to 2016: a pooled analysis of 358 population-based surveys with 1·9 million participants. Lancet Glob Health. 2018 Oct;6(10):e1077-86. https://doi.org/10.1016/S2214-109X(18)30357-7
https://doi.org/10.1016/S2214-109X(18)30... . The levels of physical inactivity are higher among females compared with males in all age groups⁸8. Guthold R, Stevens GA, Riley LM, Bull FC. Worldwide trends in insufficient physical activity from 2001 to 2016: a pooled analysis of 358 population-based surveys with 1·9 million participants. Lancet Glob Health. 2018 Oct;6(10):e1077-86. https://doi.org/10.1016/S2214-109X(18)30357-7
https://doi.org/10.1016/S2214-109X(18)30... . The economic status, measured in terms of gross domestic product, also exerts a great impact on the physical inactivity levels in the adult population. Thus, developed countries present lower levels of physical inactivity¹1. World Health Organization. World health statistics 2018: monitoring health for the SDGs, sustainable development goals. Geneva: World Health Organization; 2018. .

Data related to the economic costs of physical inactivity in low and middle-income countries are still lacking¹⁴14. Ranasinghe PD, Pokhrel S, Anokye NK. Economics of physical activity in low-income and middle- income countries: a systematic review. BMJ open 2021;11(1):e037784. https://doi.org/10.1136/bmjopen-2020-037784
https://doi.org/10.1136/bmjopen-2020-037... . In 2016, Brazil presented one of the highest prevalence of physical inactivity in the world, where 40% (95%CI: 38.9–55.3; 40.4% of males, 95%CI: 32.8–48.5; and 53.3% of females, 95%CI: 44.6–61.8) of the population did not reach the recommended level of physical activity, alongside Saudi Arabia (44.9%, 95%CI: 36.7–53.4), Germany (42.2%, 95%CI: 34–46.7), and The United States (40.0%, 95%CI: 33.0–47.3)¹1. World Health Organization. World health statistics 2018: monitoring health for the SDGs, sustainable development goals. Geneva: World Health Organization; 2018. .

The hospitalization costs resulting from NCDs attributable to physical inactivity presented in this study are quite conservative estimates of the economic impact of physical inactivity on the SUS. The information on hospitalization costs available in the Datasus considers the costs for the Brazilian SUS to pay for admissions to public and private hospitals. Several other direct and indirect costs associated with the actual expenses resulting from the hospitalization of patients for NCD are not considered. Even so, the Sistema de Informações Hospitalares of the Unified Health System (SIH – Hospital Information System/SUS) is the only database with national coverage, which originates from the hospital admission authorizations, for estimating hospitalization costs.

In this study, the cost of physical inactivity was calculated in a population over 40 years old, since hospitalization due to the NCD in a younger population (< 40 years) might have a stronger relation to other components (i.e.; genetics) than low levels of physical activity. Studies show a higher prevalence of NCD morbidity and mortality in an older population¹⁵15. Silva DA, Tremblay MS, Marinho F, Ribeiro AL, Cousin E, Nascimento BR, et al. Physical inactivity as a risk factor for all-cause mortality in Brazil (1990-2017). Popul Health Metr. 2020 Sep;18(S1 Suppl 1):13. https://doi.org/10.1186/s12963-020-00214-3
https://doi.org/10.1186/s12963-020-00214... . Furthermore, all NCD that were included to estimate the costs in our study have a decreased risk with increased levels of physical activity¹⁶16. GBD 2013 Mortality and Causes of Death Collaborators. Global, regional, and national age-sex specific all-cause and cause-specific mortality for 240 causes of death, 1990-2013: a systematic analysis for the Global Burden of Disease Study 2013. Lancet. 2015 Jan;385(9963):117-71. https://doi.org/10.1016/S0140-6736(14)61682-2
https://doi.org/10.1016/S0140-6736(14)61... .

The highest attributable factor of physical inactivity was in osteoporosis, diabetes, and ischemic heart disease. Additionally, men presented the highest population attributable fraction for cerebral vascular disease and women for diabetes and ischemic heart disease. At a national level, NCD were the cause of 739,927 hospital admissions, costing US$ 482.8 million in the year 2017 with cardiovascular and cerebral vascular disease representing the highest cost. The estimated cost attributed to physical inactivity was about 17.4%, encumbering the public health care system at about US$ 83.9 million. Considering the same level of physical inactivity in the population in 2019, the cost of NCD related to physical inactivity was about US$ 91.4 million for the Brazilian SUS.

The impact of physical inactivity in Brazil is evident, and public policy actions must be considered to change sedentary habits to more active behaviors in the populational level. Alongside the Ministry of Health, Municipal and State health secretariats must implement short, medium, and long-term action plans. There is no single, definitive solution, and the different social, cultural, and economic contexts need to be carefully evaluated and understood. The World Health Organization has established an action plan to increase the population’s level of physical activity, for a healthier world, which aims to reduce physical inactivity by 10% by 2025 and 15% by 2030²2. World Health Organization. Global action plan on physical activity 2018–2030: more active people for a healthier world. Geneva: World Health Organization; 2018. . To this end, the plan is promoting more active societies with mass participation in physical activity events, with the construction of participatory work. Therefore, creating active environments with policies to integrate active means of transport, improving connections for walking and bicycles, improving safety, and improving the population’s access to favorable public places are necessary²2. World Health Organization. Global action plan on physical activity 2018–2030: more active people for a healthier world. Geneva: World Health Organization; 2018. , as well as financing research in urban development, creating innovation mechanisms, improving data integration, and strengthening governance policies. Ideally, establishing programs on several fronts, improving structures for older people, expanding school physical education programs, prioritizing programs that reach the less active, promoting community initiatives, and incorporating physical activity in health services would be advisable²2. World Health Organization. Global action plan on physical activity 2018–2030: more active people for a healthier world. Geneva: World Health Organization; 2018. .

However, for promoting a more physically active population globally, the states need deeper effort from policymakers and stakeholders, for instance, the communication for the general public about the importance of physical activity seems inadequate. This means that the knowledge about the importance to maintain the recommended levels of physical activity in the population is still lacking¹⁷17. Hallal PC, Pratt M.

Limitations

The interpretation of these results should consider potential limitations. The RR was estimated based on self-reported physical inactivity; therefore, the estimates are expected to be conservative. Ages over 40 years old were included in the estimates, thus the results cannot be extrapolated to a younger population. The Vigitel provides data from the capital cities of the twenty-seven Brazilian states plus the federal district, which are taken as representative of the physical inactivity level of the overall state. Accounting for comorbidity, which could impact the cost attributable to physical inactivity, was impossible.

Future Directions

In this study, we estimate the cost of physical inactivity based on hospitalization costs. However, NCD also cause decreases in productivity and disability, which should be investigated.

Despite being essential to mitigate a virus spread, the measures of social isolation during the covid-19 pandemic increased de levels of physical inactivity worldwide. Therefore, the cost of the increase in physical inactivity due to the covid-19 pandemic must be further investigated.

CONCLUSIONS

This study provides evidence showing the burden of physical inactivity and the economic impact on the Brazilian SUS due to NCD hospitalization. The Brazilian SUS spends half a million reais a year, for the capital cities, due to a modifiable lifestyle. Therefore, promoting a more active community must be one of the major targets of public health care policies.
