Several studies demonstrated the association between physical inactivity and predicting the incidence of diabetes. However, these prediction models have limited validation locally. Therefore, we aim to explore the predictive value of exercise capacity in the incidence of diabetes within a high diabetes prevalence population. Methodology: A retrospective cohort study including consecutive patients free of diabetes who underwent clinically indicated treadmill stress testing. Diabetic patients at baseline or patients younger than 18 years of age were excluded. Incident diabetes was defined as an established clinical diagnosis post-exercise testing date. The predictive value of exercise capacity was examined using Harrell’s c-index, net reclassification index (NRI), and integrated discrimination index (IDI). Results: A total of 8,722 participants (mean age 46±12 years, 66.3% were men) were free of diabetes at baseline. Over a median follow-up period of 5.24 (2.17-8.78) years, there were 2,280 (≈26%) new cases of diabetes. In a multivariate model adjusted for conventional risk factors, we found a 12% reduction in the risk of incident diabetes for each one greater MET achieved (HR, 0.9; 95% CI, 0.88–0.92; P<0.001). Using Cox regression, exercise capacity improved the prediction ability beyond the conventional risk factors (AUC=0.62 to 0.66 and c-index= 0.62 to 0.68). Conclusion: Exercise capacity improved the overall predictability of incidence diabetes. Patients with reduced exercise capacity are at high risk for developing incidence diabetes. Improvement of both physical activity and functional capacity represents a preventive measure for the general population. Endocrinology & Metabolism Incidence Diabetes Exercise Capacity Metabolic equivalent of tasks (METs) Net reclassification index Predictive modeling Figures Figure 1 Figure 2 Figure 3 Background Diabetes is a major socio-economic health problem with prevalence continues to increase globally over the past decades 1 – 3 . Prevention of diabetes is a crucial health priority 4 . Strong evidence engaging higher levels of exercise capacity and lifestyle interventions has shown a protective impact on subsequent diabetes 5 – 9 . Physical activity influences both cardiorespiratory fitness (CRF), which reflects the wellbeing of the cardiovascular system, and muscular strength 10 – 13 . The significance of this evidence has led several organizations, including the American Heart Association, the American Diabetes Association, and the US. Department of Health and Human Services to include exercise capacity in their recommendations and guidelines 14 . However, it remains controversial how other diabetes-related risk factors, especially metabolic syndrome elements, might alter the association between fitness and incident diabetes 15 – 18 . The actual effect of exercise capacity on diabetes has not been fully explored as most previous data exemplify nations with low to intermediate disease prevalence 19 , 20 . These data reflect societies where the culture of Exercise is dominant, while in the Middle East and North Africa (MENA) a rise in prevalence is likely to occur in light of low activity levels among citizens. Therefore, the purpose of this study was to extend the exploration of the predictive value of exercise capacity in incidence diabetes through 1) examine the relationship between exercise capacity and incident diabetes among patients free of diabetes at baseline and 2) examine whether the relationship between CRF and incident diabetes differed across demographic characteristics and other traditional diabetes-related risk factors. Furthermore, we assess the relationship between Duke Treadmill Score, exercise capacity, and incidence of diabetes. Methods Study design and population A retrospective cohort study included consecutive patients who underwent clinically indicated exercise treadmill stress testing at King Abdulaziz cardiac center between April 2001 and December 2016. Baseline demographics, past medical history, and medications at the stress test were obtained by reviewing the electronic medical record and database search using the ICD-9 coding system. Data about the exercise stress testing were collected from the stress testing unique system (MUSE). Patients who had diabetes at the baseline before exercise stress testing, patients younger than 18 years, records with incomplete stress testing information, and non-Bruce protocol exercise stress testing were excluded from the study analysis. The study was conducted in full accordance with the protocol and the current revision of the declaration of Helsinki, the Good Clinical Practice. The study was a part of the Saudi CArdioRespiratory Fitness (SCARF) project (Study protocol: RC16/103/R - approved by King Abdullah International Medical Research Center (KAIMRC)). Exercise treadmill stress testing Patients underwent symptom-limited maximal treadmill stress testing, which followed the standard Bruce protocol. The test day was pointed as the individual study baseline. Individuals’ results of the initial exercise test were included in the database. Resting measures, heart rate, and blood pressures were measured in the seated position and were recorded immediately before each test initiation. Supervised clinicians were following American Heart Association/American College of Cardiology (AHA/ACC) guidelines for terminating the test if the patient had Exercise limiting symptoms: chest pain, shortness of breath, significant arrhythmias, abnormal hemodynamic responses, diagnostic ST-segment changes, other limiting symptoms independent of the achieved heart rate or if the participant was unwilling or unable to continue. Otherwise, patients could reach their peak attainable workload independent of the heart rate achieved. Target heart rate was calculated as 85% of the age-predicted maximal heart rate, which is the patient age subtracted from a constant value of 220. Metabolic equivalents (METs) were adopted to represent cardiorespiratory fitness status based on the workload derived from the maximal speed and grade achieved during the total treadmill time. METs results were categorized into four groups: <6, 6-9, 10-11, and ≥12 METs. Study definitions for risk factors The history of hypertension was defined as a prior diagnosis of hypertension or the use of antihypertensive medications at the time of stress testing. Dyslipidemia was defined as the prior diagnosis of any significant lipid abnormality in the medical records or lipid-lowering medication use. On a prior angiogram, patients with obstructive coronary artery disease (CAD), prior myocardial infarction, coronary angioplasty, or coronary artery bypass surgery are considered known coronary artery disease. Prior congestive heart failure was defined as a prior clinical diagnosis of systolic or diastolic heart failure. Study outcome: Incident Diabetes Incident diabetes was determined among patients without diabetes at baseline and defined as clinical diagnosis of diabetes in the medical records or clinical problem list, use of anti-hyperglycemic medications including insulin, or had lab results suggestive of diabetes post-exercise testing date. Time-to-incident diabetes was based on the time between treadmill testing and the date of the first encounter with a new diabetes diagnosis. Statistical analysis plan Study participants were divided into four groups based on their METs (<6, 6-9, 10-11, and ≥12). Categorical variables were presented in frequencies and percentages. Continuous variables were presented base on the normality of distribution as mean ± standard deviation or median and interquartile ranges, overall and in categories of METs. The four groups were compared using Chi-square or Fisher exact test for categorical variables. Analysis of Variance (ANOVA) and Kruskal Wallis test were used for continuous variables compersion, as appropriate. Cumulative incidence was presented at 5-, 10-, and 15-yr intervals via a bar graph. Kaplan-Meier cumulative incident diabetes was computed for different exercise capacity groups, and they were compared using the log-rank test. Cox regression was used to compute hazard ratios (HR) and 95% confidence intervals (CI). A forward selection technique was used to demonstrate independent predictors of incident diabetes. In each forward step, we added a related set of variables to improve our model. Therefore, gender, age, and heart rate were included in the baseline model (model 1). Subsequently, hypertension, hyperlipidemia, smoking, lung disease, previous coronary artery disease and previous congestive heart failure (model 2), antihypertensive medications, lipid-lowering medications, and proton pump inhibitors (model3), METs achieved, chronotropic incompetence, and Duke score (model 4). The primary analysis assessed the association between exercise capacity and time-free event of incident diabetes after adjusting for baseline clinical and cardiovascular risk factors. In the baseline model, we included age, gender. Subsequently, cardiovascular risk factors and related cardiac medications (Model 2), METs groups (Model 3) were added to the baseline model. We computed Harrell's concordance index (C-index) area under the Curve (AUC) and Akaike information criterion (AIC) to compare the models using this methodology developed for incidence diabetes. The selection of variables for entry consideration was based on clinical judgment, results of previous publications, and the expertise of the investigators. We also plotted a restricted cubic spline model to show the shape of the continuous relationship between METs and incident diabetes after adjustment for covariates. Finally, we examined the association between METs and incident diabetes in the subset of participants with a BMI measurement (N=6,539) ( Supplementary Table 1 ). All Statistical analyses were conducted using SAS 9.4 (SAS Institute Inc., Cary, NC, USA). Statistical significance was defined as P ≤ 0.05. Results Our study included 8,722 participants without diabetes at baseline. The mean age of study participants was 46±12 years, and 66.5% were men; 33.9% were hypertensive; 28.3% had hyperlipidemia; 5.4% were known to have prior coronary artery disease (CAD), and only a few of them had heart failure (Table 1 ).

At peak exercise, the heart rate was higher among the highest achievers (166±2 vs. 131±25 bpm, p <0.001) as well as systolic blood pressure (161±21 vs. 153±33 mmHg, p <0.001). Moreover, The highest METs was associated with a lower risk of Duke Treadmill risk, while high Duke Treadmill risk was observed in those with lower METs achieved (for low Duke score: 77.2% vs. 19.4%) and (for high Duke score 0.7% vs. 2.7%), p <0.001. Over a median follow-up period of 5.24 (IQR: 2.17-8.78) years, there were 2,280 (25.96%) new cases of diabetes. The unadjusted 5-year accumulative incidence rates of diabetes across categories of CRF (<6, 6<9, 10<11, and ≥12 METs) were 25.1%, 16.9%, 9.4%, and 6.2%, respectively. The cumulative rates of incidence of diabetes by the end of 15 years follow up period was as follows: 40.6%, 31.9%, 23.2%, and 17.3% for those who achieved <6, 6<9, 10<11, and ≥12 METs, respectively (Figure 1 ). Examination of the crude association between categories of METs and risk for incident diabetes using a Kaplan-Meier cumulative incidence curve revealed a significant trend across categories of METs (log-rank <0.001) (Figure 2 ). In a multivariate Cox regression model adjusted for potential confounders, we found a 10% reduction in the risk of incident diabetes with higher METs achieved (HR, 0.90; 95% CI, 0.88–0.92; p <0.001) (model 4B) and risk for incident diabetes reduced per each METs achieved; 13% (6<9 METs), 38% (10<11), and 52% (≥12 METs) compare to lower METs (<6 METs) p <0.001. Adding the exercise capacity information (METs achieved, CI, and Duke Risk score) improves the overall predictability of the model (model 4A) over the baseline model ( Table 2 ). We examined the predictive value of the finding of exercise stress testing, and we found superiority of METs groups in prediction incidence diabetes above the other models resulted in a significant reclassification of the study cohort and significant improvement of the area under the curve above the primary model ( Table 2 ) A non-linear inverse relationship was observed between baseline exercise capacity and risk of incident diabetes after adjusted for known cofounders. A gradual decline in the risk of development of diabetes was observed for every improvement of exercise capacity (METs increase) above 6 METs (Figure 3 ) Discussion In this study, we investigated the relationship between CRF level and the development of type 2 diabetes among Saudi patients. To the best of our knowledge, this is the first large and demographically diverse cohort to examine the association between CRF estimated by METs using a standard test (Bruce protocol) by exercise treadmill testing and risk of incident diabetes in the Saudi population. We have shown that higher fitness was strongly associated with a lower risk of diabetes among patients without diabetes at baseline, such that every increment of fitness by 1 MET was associated with a 12% lower risk of developing diabetes. Another important finding in our study was the inverse linear relationship between CRF and diabetes, which notably did not show evidence of plateauing or reversal at higher levels of CRF. This association was observed regardless of age, sex, and other common diabetes-related risk factors. Several small cross-sectional studies have shown that exercise capacity is inversely associated with impaired glycemic control 21 , the metabolic syndrome 22 , diabetes 23 , 24 and positively associated with glucose disposal rate 25 and insulin sensitivity 26 . Unfortunately, these studies have been small and confined to limited demographic settings (single-sex, racial group, or age-group). To our knowledge, only two prospective studies have been conducted on the relationship between cardiorespiratory fitness level and the incidence of type 2 diabetes 27 , 28 . Lynch et al. 29 reported that Finnish men with a higher cardiorespiratory fitness level, measured using a bicycle ergometer, had a significantly lower risk of developing type 2 diabetes over the 4-year follow-up period. In a study of U.S. men with the study group consisting primarily of Caucasian men, Wei et al. 30 found a significant inverse relationship between cardiorespiratory fitness (measured by treadmill time) and the incidence of type 2 diabetes. Moreover, previous studies utilized self-reported PA as a surrogate for fitness. PA represents behavior and may not reflect one’s health compared to CRF. The mechanism that links the relationship between fitness and incident diabetes is a subject of much discussion. Sato et al. 31 demonstrated that individuals with low cardiorespiratory fitness have high insulin resistance. Additionally, Ivy and Kuo 32 reported that individuals with lower levels of CRF have fewer glucose transporters compared with those more fit. It is thought that this relationship is mediated by positive changes in one's body tissue profile, namely, 1) reduced adiposity, a significant risk factor for diabetes 33 , increased skeletal muscle, a critical tissue in postprandial glucose uptake 25 , 34 . Moreover, higher fitness has been shown to increase insulin sensitivity and glucose disposal directly35 . However, it is also possible that fitness partly reflects one’s native genetic state 36 independent of physical activity. For example, several studies have shown that impaired oxidative respiration due to mitochondrial dysfunction 37 underlies the pathogenesis of diabetes. Such a state would also manifest as reduced fitness independent of one’s physical activity. Study Limitations and Strengths Our study is not without limitations. First, cardiovascular health is independently associated with behaviors that may represent the causal contributing to fitness. Unfortunately, we are unable to assess these behaviors in our study formally. Second, incident diabetes was based on medical records and administrative claims files, which were not collected initially to examine diabetes. As a result, our study did not include study protocol–based direct measurements of hemoglobin A1c, blood glucose, or oral glucose tolerance testing. Because of this, several people with undiagnosed diabetes may have been included in our study population or missed as incident cases, attenuating our results. Third, our study population comprised persons referred for stress testing, which undoubtedly carries a higher burden of cardiovascular disease at baseline than the general population and may have led to referral bias. That limits our study's generalizability. Fourth, residual confounding is always a concern with observational studies, especially with covariates assessed via the medical record rather than a direct measurement. Finally, our study reports a single center's experience with its unique practice patterns and mode of operation. Thus, although the cohort studied was diverse, it may not represent the entire adult population of Saudi Arabia. On the other hand, our study has some strengths. The standard stress testing, the Bruce protocol treadmill test, characterized fitness rather than self-reporting physical activity. This way is readily interpreted in clinical settings. Furthermore, our study sample was a large and diverse sample, which adequately powered our study. Conclusion In conclusion, our results showed a strong inverse relationship between cardiorespiratory fitness and the development of type 2 diabetes. This relationship was independent of other traditional risk factors for diabetes. This study provides further supporting evidence of the benefits of higher overall fitness. Maintaining a high cardiorespiratory fitness level may contribute to the prevention of type 2 diabetes; therefore, we hope our findings will encourage health professionals to advise the general public and diabetics to lead an active lifestyle and improve their fitness levels. Prospective future studies are required to evaluate these findings further.

Baseline demographics, past medical history, and medications at the stress test were obtained by reviewing the electronic medical record and database search using the ICD-9 coding system. Data about the exercise stress testing were collected from the stress testing unique system (MUSE). Patients who had diabetes at the baseline before exercise stress testing, patients younger than 18 years, records with incomplete stress testing information, and non-Bruce protocol exercise stress testing were excluded from the study analysis. The study was conducted in full accordance with the protocol and the current revision of the declaration of Helsinki, the Good Clinical Practice.

The test day was pointed as the individual study baseline. Individuals\u0026rsquo; results of the initial exercise test were included in the database. Resting measures, heart rate, and blood pressures were measured in the seated position and were recorded immediately before each test initiation. Supervised clinicians were following American Heart Association/American College of Cardiology (AHA/ACC) guidelines for terminating the test if the patient had Exercise limiting symptoms: chest pain, shortness of breath, significant arrhythmias, abnormal hemodynamic responses, diagnostic ST-segment changes, other limiting symptoms independent of the achieved heart rate or if the participant was unwilling or unable to continue. Otherwise, patients could reach their peak attainable workload independent of the heart rate achieved. Target heart rate was calculated as 85% of the age-predicted maximal heart rate, which is the patient age subtracted from a constant value of 220. Metabolic equivalents (METs) were adopted to represent cardiorespiratory fitness status based on the workload derived from the maximal speed and grade achieved during the total treadmill time. METs results were categorized into four groups: \u0026lt;6, 6-9, 10-11, and \u0026ge;12 METs.\u003c/p\u003e \u003c/div\u003e \u003cdiv id=\"Sec5\" class=\"Section2\"\u003e \u003ch2\u003eStudy definitions for risk factors\u003c/h2\u003e \u003cp\u003eThe history of hypertension was defined as a prior diagnosis of hypertension or the use of antihypertensive medications at the time of stress testing.

Continuous variables were presented base on the normality of distribution as mean \u0026plusmn; standard deviation or median and interquartile ranges, overall and in categories of METs. The four groups were compared using Chi-square or Fisher exact test for categorical variables. Analysis of Variance (ANOVA) and Kruskal Wallis test were used for continuous variables compersion, as appropriate. Cumulative incidence was presented at 5-, 10-, and 15-yr intervals via a bar graph.\u003c/p\u003e \u003cp\u003eKaplan-Meier cumulative incident diabetes was computed for different exercise capacity groups, and they were compared using the log-rank test. Cox regression was used to compute hazard ratios (HR) and 95% confidence intervals (CI). A forward selection technique was used to demonstrate independent predictors of incident diabetes. In each forward step, we added a related set of variables to improve our model. Therefore, gender, age, and heart rate were included in the baseline model (model 1). Subsequently, hypertension, hyperlipidemia, smoking, lung disease, previous coronary artery disease and previous congestive heart failure (model 2), antihypertensive medications, lipid-lowering medications, and proton pump inhibitors (model3), METs achieved, chronotropic incompetence, and Duke score (model 4). The primary analysis assessed the association between exercise capacity and time-free event of incident diabetes after adjusting for baseline clinical and cardiovascular risk factors. In the baseline model, we included age, gender. Subsequently, cardiovascular risk factors and related cardiac medications (Model 2), METs groups (Model 3) were added to the baseline model. We computed Harrell's concordance index (C-index) area under the Curve (AUC) and Akaike information criterion (AIC) to compare the models using this methodology developed for incidence diabetes. The selection of variables for entry consideration was based on clinical judgment, results of previous publications, and the expertise of the investigators. We also plotted a restricted cubic spline model to show the shape of the continuous relationship between METs and incident diabetes after adjustment for covariates. Finally, we examined the association between METs and incident diabetes in the subset of participants with a BMI measurement (N=6,539) (\u003cb\u003eSupplementary Table 1\u003c/b\u003e).

In a multivariate Cox regression model adjusted for potential confounders, we found a 10% reduction in the risk of incident diabetes with higher METs achieved (HR, 0.90; 95% CI, 0.88\u0026ndash;0.92; \u003cem\u003ep\u003c/em\u003e\u0026lt;0.001) (model 4B) and risk for incident diabetes reduced per each METs achieved; 13% (6\u0026lt;9 METs), 38% (10\u0026lt;11), and 52% (\u0026ge;12 METs) compare to lower METs (\u0026lt;6 METs) \u003cem\u003ep\u003c/em\u003e\u0026lt;0.001.

We examined the predictive value of the finding of exercise stress testing, and we found superiority of METs groups in prediction incidence diabetes above the other models resulted in a significant reclassification of the study cohort and significant improvement of the area under the curve above the primary model (\u003cb\u003eTable 2\u003c/b\u003e)\u003c/p\u003e \u003cp\u003e \u003c/p\u003e \u003cp\u003eA non-linear inverse relationship was observed between baseline exercise capacity and risk of incident diabetes after adjusted for known cofounders.

We have shown that higher fitness was strongly associated with a lower risk of diabetes among patients without diabetes at baseline, such that every increment of fitness by 1 MET was associated with a 12% lower risk of developing diabetes.

First, cardiovascular health is independently associated with behaviors that may represent the causal contributing to fitness. Unfortunately, we are unable to assess these behaviors in our study formally. Second, incident diabetes was based on medical records and administrative claims files, which were not collected initially to examine diabetes. As a result, our study did not include study protocol\u0026ndash;based direct measurements of hemoglobin A1c, blood glucose, or oral glucose tolerance testing. Because of this, several people with undiagnosed diabetes may have been included in our study population or missed as incident cases, attenuating our results. Third, our study population comprised persons referred for stress testing, which undoubtedly carries a higher burden of cardiovascular disease at baseline than the general population and may have led to referral bias. That limits our study's generalizability. Fourth, residual confounding is always a concern with observational studies, especially with covariates assessed via the medical record rather than a direct measurement. Finally, our study reports a single center's experience with its unique practice patterns and mode of operation. Thus, although the cohort studied was diverse, it may not represent the entire adult population of Saudi Arabia.\u003c/p\u003e \u003cp\u003eOn the other hand, our study has some strengths. The standard stress testing, the Bruce protocol treadmill test, characterized fitness rather than self-reporting physical activity. This way is readily interpreted in clinical settings. Furthermore, our study sample was a large and diverse sample, which adequately powered our study.\u003c/p\u003e \u003c/div\u003e"},{"header":"Conclusion","content":"\u003cp\u003eIn conclusion, our results showed a strong inverse relationship between cardiorespiratory fitness and the development of type 2 diabetes.

Maintaining a high cardiorespiratory fitness level may contribute to the prevention of type 2 diabetes; therefore, we hope our findings will encourage health professionals to advise the general public and diabetics to lead an active lifestyle and improve their fitness levels.

Several studies demonstrated the association between physical inactivity and predicting the incidence of diabetes. However, these prediction models have limited validation locally. Therefore, we aim to explore the predictive value of exercise capacity in the incidence of diabetes within a high diabetes prevalence population.\u003c/p\u003e\u003cp\u003e\u003cstrong\u003eMethodology:\u003c/strong\u003e A retrospective cohort study including consecutive patients free of diabetes who underwent clinically indicated treadmill stress testing. Diabetic patients at baseline or patients younger than 18 years of age were excluded. Incident diabetes was defined as an established clinical diagnosis post-exercise testing date. The predictive value of exercise capacity was examined using Harrell’s c-index, net reclassification index (NRI), and integrated discrimination index (IDI).\u003c/p\u003e\u003cp\u003e\u003cstrong\u003eResults:\u003c/strong\u003e A total of 8,722 participants (mean age 46±12 years, 66.3% were men) were free of diabetes at baseline. Over a median follow-up period of 5.24 (2.17-8.78) years, there were 2,280 (≈26%) new cases of diabetes. In a multivariate model adjusted for conventional risk factors, we found a 12% reduction in the risk of incident diabetes for each one greater MET achieved (HR, 0.9; 95% CI, 0.88–0.92; P\u0026lt;0.001). Using Cox regression, exercise capacity improved the prediction ability beyond the conventional risk factors (AUC=0.62 to 0.66 and c-index= 0.62 to 0.68).\u003c/p\u003e\u003cp\u003e\u003cstrong\u003eConclusion:\u003c/strong\u003e Exercise capacity improved the overall predictability of incidence diabetes. Patients with reduced exercise capacity are at high risk for developing incidence diabetes. Improvement of both physical activity and functional capacity represents a preventive measure for the general population.\u003c/p\u003e","manuscriptTitle":"Prognostic Value of Exercise Capacity In Incidence Diabetes: A Country With High Prevalence of Diabetes","msid":"","msnumber":"","nonDraftVersions":[{"code":2,"date":"2022-01-05 14:18:59","doi":"10.21203/rs.3.rs-1147869/v2","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Major revision","date":"2022-01-11T09:18:39+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2021-12-18T21:40:55+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"a3fe0cbc-0484-460d-b022-b4522ac13561","date":"2021-12-17T02:47:55+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2021-12-17T00:27:04+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2021-12-17T00:24:18+00:00","index":"","fulltext":""},{"type":"editorInvited","content":"","date":"2021-12-16T23:55:08+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2021-12-16T23:53:00+00:00","index":"","fulltext":""},{"type":"submitted","content":"BMC Endocrine Disorders","date":"2021-12-15T05:43:04+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"
