Background: Diabetes mellitus with co-existing hypertension contributes to increased morbidity and mortality. The study aimed to investigate the impact of the patients' physical activity status and the type of cooking oil consumed by patients in their daily routine on glycemic profile, lipid profile, the hypertensive profile of the patients, and the length of stay and overall cost of the treatment.

Methods: A prospective observational study. All the patients who referred to the medicine department of the three different hospitals located in Moga, City Punjab and those who were hospitalized due to diabetes mellitus (type-I and type-II) with co-existing hypertension were asked to participate in the study.

Results: The patients' mean age was found to be M= 53.85, SD= 11.54 years. Out of 1914 patients, 914 were male (47.8%); it was observed that the majority of the patients 525 (27.43%) in North India using butter or ghee- clarified butter as edible oil, followed by mustard oil 517 (27.01%) patients. About 345 (18.03%) of the patients consume soybean oil, whereas 226 (11.81%) of the patients like sunflower oil.

Discussion: This study explored that cooking oil and physical activity are associated with length of stay in days & overall cost of the treatment, respectively. Our study results revealed that the type of oil compared with the treatment's overall cost was significant for olive oil, soybean oil, and groundnut oil.

Conclusion: The study revealed that moderate and low physical activity increases the length of stay compared to high physical activity. The consumption of olive oil as a regular food habit in daily routine decreases patients' length of stay with diabetes with coexisting hypertension when doing high physical activity but increases the overall cost of treatment.

The present study revealed that physical activity as well as the cooking oil used in daily routine as food habit correlates length of stay and cost of treatment.
Female patients suffering from D.M. (type-I and type-II) with co-existing hypertension had a lower mean length of stay and cost of treatment than male patients.
In North India, majority of D.M. (type-I and type-II) with co-existing hypertension patients consume butter, ghee- clarified butter as compared to other oils which increase the cost and LOS of treatment and least chooses rice bran oil.
Olive oil and mustard oil as a regular food habit lowers the length of stay, whereas increases the overall cost of treatment compared to rice bran oil.

Diabetes mellitus (D.M.) with co-existing hypertension (HTN) contributes to increased morbidity and mortality¹. The estimates reported by Domeikiene A et al. (2014) that by 2030 the number of people with diabetes will have risen to 552 million². The study aimed to investigate the impact of the patients' physical activity status and the type of cooking oil consumed by patients in their daily routine on glycemic profile, lipid profile, the hypertensive profile of the patients, and the length of stay and overall cost of the treatment. The study also aimed to investigate and compare the prevalence of diabetes with co-existing hypertension among men and women in Moga, a city located in Punjab state of India consuming different types of oils and doing different kinds of physical activity.

Multiple studies from western countries suggest that type of oil used by the patients in their regular diet and physical activity has a protective role against the development of D.M. and HTN. The Chinese study conducted by Yuzo S et al. (2003) elaborated in detail about physical exercise in type-2 diabetes mellitus. The results of various follow-up studies have revealed that physical activity is not only useful in preventing type-2 diabetes mellitus and improving disease status³. The patients suffering from diabetes mellitus with co-existing hypertension, the risk of death from vascular causes is 2.32 times higher than in persons without diabetes, and diabetes was once considered a coronary heart disease (CHD) risk equivalent⁴.

In particular, no study to our knowledge has been conducted by taking these variables for the North region of India, especially Punjab. The population staying in Punjab suffers more from D.M. and HTN than other states of India ⁵.

Objectives

This study objective is to provide up-to-date information regarding the physical activity and type of cooking oil consumed by patients in their daily routine and their impact on glycemic profile, lipid profile, the hypertensive profile of the patients, and the length of stay and cost. Therefore, the present study was planned to increase awareness and contribute to the length of stay and treatment cost for diabetes patients with co-existing hypertension. The primary risk factor for cardiovascular disease in diabetes mellitus is dyslipidemia ⁶. Therefore, the lipid profile parameters, along with the glycaemic and hypertensive profile of the patients, were also studied. It was also observed from literature and as per physical activity guidelines for Americans for adults that substantial health benefits can be obtained by doing (30 minutes to 2 hours) a week of moderate-intensity physical activity or (1 hour and 15 minutes) a week of vigorous-intensity physical activity. In contrast, aerobic exercise should be spread throughout the week⁷. Therefore, we analyzed the type of oil used by the patients in their regular diet and status of physical activity and investigated their impact on glycemic profile, lipid profile, the hypertensive profile of the patients, length of stay, and overall cost of the treatment.

Setting

In this observational study, all the patients referred to the medicine department of the three different hospitals of Moga, city located in Punjab state of India ^8,9 were enrolled in the study. The patients hospitalized due to diabetes mellitus (type-I and type-II) with co-existing hypertension from April 2017 to August 2020 were asked to participate in the study.

The present study is part of the ongoing research entitled "Drug utilization study of diabetes and hypertension at tertiary care hospital." The population size of the Moga city was found N= 2.98 lakhs⁸. The sample size is calculated with the 'Epi Info' software^10,11. A total of 2622 patients suffering from diabetes mellitus (D.M.) and hypertension (HTN) were screened during the study period. Out of the 2622 patients, 1914 patients were enrolled in the statistical analysis. A total of 708 patients were excluded while analyzing data because of missing value; some patients were lost during the follow-up. Thus, a total sum of 1914 patients were included for final analysis. Patients diagnosed with diabetes mellitus and hypertension with or without complications admitted to (IPD) in-patient department of the hospital. The study's inclusion criteria include patients visiting the hospital for follow-up, both genders with age >18 years, and diabetes with co-existing hypertension. The exclusion criteria include that patients were not willing to participate in the study.

Institutional Ethics Committee (IEC-ISFCP, Moga) ISF College of Pharmacy, Moga, Punjab approved the study (Ref. No. ECR/296/Indt/PB/2017/ISFCP/136). The confidence interval of the study is chosen as 97%¹². All statistical tests were carried out at the two-sided 3% significance level by statistical analysis software SPSS ver. 25. The study data collection form includes a questionnaire containing 105 variables. The lab investigations like blood pressure (B.P.) systolic of the patient on admission, B.P. diastolic of the patient admission, fasting blood sugar of the patient at admission, the random blood sugar of the patient at admission, HbA₁c measurement of the patient, HDL in mg/dL of the patient, LDL in mg/dL of the patient, triglyceride level in mg/dL of the patient, VLDL levels in mg/dL of the patient, creatinine levels in mg/dL, were recorded during the study. Pharmacoeconomic parameters like cost of drug, direct and non-direct cost of the treatment were also recorded during the study and the length of stay in days. A pre-developed and validated tool (DCF) data collection form and patients' informed consent (PIC) were used to collect patient data. All study costs were recorded in INR, and pharmacoeconomic variables were converted to USD (INR: 73.35= 1 USD).

The mean age of the patients suffering from diabetes mellitus (type-I and type-II) with co-existing hypertension (µ) and standard deviation (S.D.) was found to be (M = 53.85, SD = 11.54) years. The normality test was performed, which was found normally distributed Kolmogorov-Smirnov and Shapiro-Wilk (p=0.36 and 0.223), respectively^13–15. Out of 1914 patients, 914 were male (47.8%), followed by female 1000 (53.65%).

The study's independent variable was taken as a cooking oil and physical activity status of the patients, whereas the length of stay and overall cost of the treatment was taken as a dependent variable for the study. During the investigation, it was found that nine different types of cooking oil were used by the patients suffering from D.M. (type-I and type-II) with co-existing hypertension in their daily routine as food habits as soybean oil, corn oil, mustard oil, olive oil, coconut oil, butter, ghee- clarified butter, groundnut oil, sunflower oil, and rice bran oil. The descriptive statistics of the patients' oil used in diet and physical activity status are represented in Figure 1 and Table 1. The patients use the cooking oil in their daily routine as food habits are coded as 0 to 9. The three different physical categories were recorded during the study period as 0-low, 1-moderate, 2-high physical activity. The data shows out of 1914 patients enrolled in the study, soybean oil was used as cooking oil by 345 patients, followed by butter or ghee- clarified butter by 525 patients, mustard oil 517 patients, corn oil 32 patients, olive oil 147 patients, coconut oil 46 patients, groundnut oil 48 patients, sunflower oil 226 patients and rice bran oil by 28 patients.

The descriptive statistics of the variable physical activity status of the patients were also recorded. Out of 1914 patients enrolled in the study, 729 patients were doing low physical activity daily, followed by 969 patients doing moderate physical activity, whereas 216 patients were doing high physical activity daily as their daily routine. Low physical activity is represented as 15-30 minutes in a day; moderate physical activity is described as 30 minutes to 1 hour in a day; high physical activity is represented as 1-2-hour in a day, including yoga (breathing exercise), aerobics, and morning and evening walk.

The descriptive statistics of type of cooking oil used by patients in their daily routine showed that most of the patients 525 (27.43%) in North India use butter or ghee- clarified butter as edible oil, followed by mustard oil 517 (27.01%) patients. About 345 (18.03%) of the patients consume soybean oil, whereas 226 (11.81%) of the patients like

sunflower oil. It was also observed that only 32 (1.67%) patients are using corn oil as an edible oil in their food. Whereas olive oil was used by 147 (7.68 %) of the patients. The coconut oil, which is most common in South India, was used by 46 (2.40%), groundnut oil 48 (2.51%), and rice bran oil 28 (1.46%). The type of cooking oil used by D.M. and hypertensive patients is represented in Table 1. Figure 1 Simple bar chart represent means of the length of stay in days by type of cooking oil used by patients

On examination of the physical activity of the patients, it was seen that majority of the patients are doing moderate physical activity 969 (50.63%) as compared to low physical activity 729 (38.09%) followed by high physical activity 216 (11.29%). Similar results were obtained in a study conducted by Fock K. et al. (2013) ¹⁶

The mean length of stay (days) was found to be M=6.43, SD=2.31 days. Independent-T test was performed to determine the mean length of stay (days) between male and female patients. The results of the test were found significant. This study confirms that the mean length of stay (days) of female patients suffering from D.M. (type-I and type-II) with co-existing hypertension had statistically significantly lower mean length of stay (days) (M= 5.50, SD= 0.38) as compared to male patients (M= 6.45, SD=0.52), t (1912) = 2.428, p=0.020. The mean difference of 0.95 days was observed. Figure 2 represents the difference in mean length of stay in days by gender of the patient.

The descriptive statistics of laboratory investigations like the patients' lipid profile, the patients' glycemic profile, and the patients' hypertensive profile were also studied during the study period. The results of lab investigations revealed that the mean cholesterol level of the patients (M= 251.86, SD=30.75) mg/dL, whereas the mean high-density lipoproteins (HDL) found to be (M=31.11, SD=8.89) mg/dL, low-density lipoproteins (LDL) found to be (M=176.27, SD=25.36) mg/dL, the mean level of triglyceride was found to be (M=219.55, SD=44.82) mg/dL, and mean of very-low-density lipoproteins (VLDL) (M= 42.43, SD=5.26) mg/dL.

On the evaluation of the blood glucose profile of the patients, it was observed that mean fasting blood sugar (FBS) (M= 272.9 SD=12.15) mg/dL as compared to another study results 181.57 mg/dL conducted by Shantakumari N et al. (2013)⁶, mean random blood sugar (RBS) was found to be (M=315.9, SD=14.13) mg/dL, and mean HbA1c measurement (M=7.91, SD=1.01) %. A paired sample t-test was conducted to compare FBS and RBS level in mg/dL of the patients during admission to the hospital with FBS and RBS level in mg/dL during discharge. The mean FBS during discharge from the hospital was found to be 137.29 mg/dL, whereas the mean RBS during discharge was found to be 186.93 mg/dL. The mean difference was found significant (FBS: p=0.001, RBS: p=0.001). The mean difference between FBS during admission and discharge was 135.61 (6.08) mg/dL, whereas the mean difference between RBS during admission in hospital and discharge from hospital was 128.97 (6.96) mg/dL. Table 5 represents the details of the blood glucose profile, hypertensive profile, and lipid profile of the patients with oil during admission. The minimum FBS and RBS were found in the case of olive oil (FBS: M= 232.5, RBS: M=270.1) mg/dL. At the same time, the minimum SBP and BPD were also found in the case of olive oil (BPS: M= 170, BPD: M=90) mmHg. The highest FBS was observed in rice bran oil (FBS: M= 296.2 mg/dL), whereas the maximum RBS was obtained in the case of soybean oil (M=350.1 mg/dL). The maximum HbA₁C is observed in groundnut oil (M= 8.6 percent), as shown in Table 5.

On the evaluation of the hypertensive profile of the patients, two lab parameters were evaluated. The mean systolic blood pressure (SBP) was found to be (M=195.03, SD=10.15) mmHg, followed by a mean diastolic blood pressure (DBP) (M= 100.33, SD=8.84) mmHg, which revealed all patients suffering from HTN. The mean serum creatinine (M=2.8, SD=0.90) mg/dL was observed.

The pharmacoeconomic parameters like the overall cost of the treatment, cost of medical supplies and equipment, cost of diagnostic tests ($), and cost of the drug ($) were also evaluated for the study's patients. The pharmacoeconomic parameters were chosen as per the recommendation of Richard E et al. (2003) for the treatment's direct and indirect cost ¹⁷. On evaluating pharmacoeconomic parameters, it was observed that the overall (direct and non-direct) mean cost of the treatment was found to be (M=309.33, SD=78.64) USD. The mean cost of medical supplies and equipment was found to be (M=21.37, SD=3.77) USD. On evaluation, it was also found that the mean cost of diagnostic tests was found to be (M=14.85, SD=2.63) USD, followed by the mean cost of the drug (M=13.54, SD=7.0) USD. The data of pharmacoeconomic parameters, the patients' hypertensive profile, the patients' lipid profile, and the patients' glucose profile are represented in Table 1.

The General Linear Model (ANCOVA) was performed to find out the correlation of cooking oil and physical activity status of the patients with a length of stay and overall cost of the treatment for the patients suffering from D.M. (type-I and type-II) with co-existing hypertension.

Table 2 represents the type of cooking oil used by the patients as an independent variable, whereas the length of stay in days and overall cost of the treatment (USD) per day dependent variable. The descriptive statistics of the length of stay and cost of the treatment reveals that the highest cost of the treatment was observed in patients consuming olive oil 147 patients (M=82.65, SD=48.44) USD followed by groundnut oil 48 patients (M=71.51, SD=78.92)

In correlation with physical activity status, the highest cost of the treatment was observed in patients consuming soybean oil and doing high physical activity ten patients (M=85.60, SD=35.47) USD, whereas the length of the stay reduces (M=4.80, SD= 2.7) days.

The group-wise statistics reveal that the lowest length of stay was observed in patients consuming olive oil and doing high physical activity. For patients consuming olive oil and doing high physical activity, the length of stay in days (LOS) was found to be 130 (M=3.49, SD=1.87) and the overall cost of treatment in USD (OCT) 130 (M=84.18, SD 50.86). Patients consuming olive oil and doing moderate physical activity, LOS was found to be 7(M=4.0, SD=1.15), and OCT was found to be 7 (M=69.21, SD= 25.09). Patients consuming olive oil and doing low physical activity, LOS was found to be 10 (M=4.90, SD=1.59), and OCT was found to be 10 (M=72.18, SD= 16.75). A maximum of 525 patients was consuming butter, ghee- clarified butter. The mean LOS was found to be (M=7.80, SD=1.77), whereas the mean OCT was found to be (M=42.67, SD=11.83). It was also revealed that only 28 patients consumed rice bran oil, and maximum LOS was found to be (M=9.61, SD=2.39), whereas the OCT was found to be (M=36.52, SD=3.87). The length of stay in days and the overall cost of the treatment per day is represented in Table 2.

The General Linear Model (GLM) (ANCOVA) analysis of covariance was performed to find out the impact and relationship of the cooking oil used by the patients and physical activity as independent variable whereas the length of stay in days and overall cost of the treatment (USD) per day dependent variable. Levene's test was found > 0.03, which shows equal variances. The results of ANCOVA show that cooking oil and physical activity are associated with length of stay in days & overall cost of the treatment per day (P = 0.001 and P = 0.001), respectively. The results of dependent variable length of stay was found significant (F (8,1903) = 8.25, P < 0.001), physical activity (F (8,1903) = 2.89, P < 0.001) as shown in Table 3.

When compared with the length of stay, all types of oil were found significant (p = value of all kinds of cooking oil was found 0.001) compared to physical activity when compared length of stay in days; the results were also found significant. The significant value for moderate physical activity was found to be (p=0.030), whereas, for low physical activity, the significant value was found to be (p=0.001), as shown in Table 4. The estimated marginal means of the length of stay in days with the type of cooking oil with physical activities is represented in Figure 3 whereas Figure 4 represent the estimated marginal means of the overall cost of the treatment per day in INR with the type of cooking oil with physical activities.

The results of all types of oil when compared with the overall cost of the treatment it was found that significant results were obtained for the olive oil (p=0.001), corn oil (p=0.001), soybean oil (p=0.030), and groundnut oil (p=0.001). Simultaneously, the non-significant results were obtained in mustard oil, coconut oil, butter, ghee, and groundnut oil compared to rice bran oil. When compared the overall cost of the treatment, the type of physical activity was also found significant. The significant value for moderate physical activity was found to be (p=.026), whereas low physical activity significant value was found to be (.017) compared to high physical activity, as shown in Table 4.

The parameter estimates data of the dependent variable length of stay in days revealed that moderate physical activity resulted in increased length of stay suggested by β of 0.09 days, while low physical activity increases over β of 0.39 days compared to high physical activity. Whereas the parameter estimates data of dependent variable overall cost of the treatment per day revealed that moderate physical activity resulted in the lower overall cost of the treatment suggested by β of -503.8 INR (-$6.87), while low physical activity lowers the cost over β of --752.8 INR (-$10.26) compared to high physical activity.

On the evaluation of results of the cooking oil, the parameter estimates data of the dependent variable length of stay in days revealed that consumption of olive oil as a regular food habit lower the length of stay suggested by β of -5.26 days whereas increases the overall cost of treatment as indicated by β of 2714.6 INR ($37.01). The results of mustard oil as a regular food habit lower the length of stay shown by β of -4.17 days, whereas increases the overall cost of treatment as suggested by β of 1732.5 INR ($23.62) as compared to rice bran oil.

The study also highlighted that reason for low physical activity and exercise was found to be laziness to wake up early in the morning for a morning walk in 426 (58.43%), Lack of power, energy, or physical stamina 222 (30.45%), and personal health 81 (11.11%).

Main outcome measure:

This study reveals that the mean length of stay (days) of the patients suffering from D.M. and hypertensive patients is 6 to 7 days, as compared with 5.98 days reported by Rajhans A et al. (2019)¹⁸. Our study confirms that female patients suffering from D.M. (type-I and type-II) with co-existing hypertension had a statistically significantly lower mean length of stay than male patients. At the same time, opposite results were observed in male (56.7 %) patients in the study reported by Hiroki F et al. (2019)¹⁹.

In this study, it was observed that the majority of the patients in North India using butter or ghee- clarified butter as edible oil, followed by mustard oil. The study conducted by Kumar A et al. (2018) discussed in detail the importance and health benefits of using ghee (trans-fatty acids) as cooking oil ²⁰. Kumar A et al. (2018) also reported that North Indians consume ghee more than other oils in their daily routine ²⁰. The least used cooking oil used by patients daily as food habit was groundnut oil and rice bran oil. Manchanda S et al. (2016) reported a similar view in his study²¹.

This study reveals that the highest cost of the treatment was observed in patients consuming olive oil 82.65 USD, followed by 71.51 USD groundnut oil. In correlation with physical activity status, the highest cost of the treatment was observed in patients consuming soybean oil and doing high physical activity M=85.60 USD, whereas the length of the stay reduces 2.7 days.

This study reveals that the lowest length of stay was observed in patients consuming olive oil, whereas doing high physical activity. Patients consuming olive oil and doing high physical activity, length of stay in days (LOS) was found to be 3.49 days, and the overall cost of treatment in USD 84.18. The cost of treatment is compared with other studies held in different years; the survey reported by Wolfgang R et al. (2007) have reported the cost of therapy 86.7 USD in 1994, 172.1 USD in 2004 ²². Patients consuming olive oil and doing moderate physical activity LOS was found 4.0 days, and OCT was found 69.21 USD. Patients consuming olive oil and doing low physical activity LOS was found 4.90 days, and OCT was found 72.18 USD. It was also revealed that the maximum mean length of stay was found for the patients consuming rice bran oil 9.61 days, with the overall cost of treatment 36.52 USD. The treatment's direct cost was 188.5 USD, whereas the in-direct cost of treatment 39.1 USD. The overall cost of treatment was found to be 295.6 USD. At the same time, the overall cost of therapy per day was found to be 46.1 USD.

Our study results show that cooking oil and physical activity are associated with length of stay in days & overall treatment costs. The results of the dependent variable length of stay and physical activity were found significant. The results of all types of oil compared with the length of stay showed substantial results, whereas physical activity when the compared length of stay in days was also significant. Our study results revealed that the type of oil compared with the treatment's overall cost was highly significant for olive oil, soybean oil, and groundnut oil. Simultaneously, the non-significant results were obtained in mustard oil, coconut oil, butter, ghee, and groundnut oil compared to rice bran oil. Previous studies suggest that Indian cooking conditions subject oil to very high temperatures, like in deep frying, at 170 degrees Celsius ²³. Katragadda H et al. (2010) reported that certain oils, especially soyabean oil, mustard oil, and ghee, can degrade quickly to toxic components like free radical and transfat, melondialdehyde (MDA), which are potentially mutagenic and atherogenic²⁴. The minimum FBS and RBS were found in olive oil simultaneously. The minimum SBP and BPD were also found in the case of olive oil. The highest FBS was observed in rice bran oil, whereas the maximum RBS was obtained in soybean oil. The maximum HbA₁C is observed in groundnut oil followed by butter, ghee- clarified butter. The minimum HbA₁C is observed in olive oil (6.7%). The maximum level of HDL is observed in olive oil (M= 36.2 mg/dL).

Compared with the overall cost of the treatment, the type of physical activity was also found significant. The results of moderate physical activity were found significant as compared to high physical activity. It was also revealed that moderate physical activity resulted in an increased length of stay by 0.09 days, while low physical activity increases 0.39 days compared to high physical activity. Simultaneously, the overall cost of the treatment per day revealed that moderate physical activity lowers the overall cost of the treatment by -503.8 INR (-$6.87), while low physical activity reduces the cost -752.8 INR (-$10.26) compared to high physical activity. Our study results revealed that olive oil consumption as a regular food habit lowers the length of stay by -5.26 days, whereas it increases the overall cost of treatment by 2714.6 INR ($37.01). The mustard oil as a regular food habit lowers the length of stay -4.17 days, whereas it increases the overall cost of treatment by 1732.5 INR ($23.62) compared to rice bran oil. The oils are a specific diet component that provides essential fatty acids and facilitates various other vitally crucial nutrients for normal physiological functions²⁵. The study also highlighted that reason for low physical activity and exercise to be laziness to wake up early in the morning for a morning walk in most of the patients as the same reported in other studies²⁶. Lack of power, energy, or physical stamina and personal health issue were barriers identified in this study and others for low physical activity²⁶.

Our study concludes that moderate and low physical activity increases the length of stay compared to high physical activity. This study is the first of its kind in North India and is important for many reasons. First, the consumption of olive oil as a regular food habit in daily routine decreases the length of stay of patients who have diabetes with coexisting hypertension when doing the high physical activity but increases the overall cost of treatment. Mustard oil as a regular food habit lowers the length of stay, whereas it increases the overall cost of treatment compared to rice bran oil. The study also concludes that female patients suffering from D.M. (type-I and type-II) with co-existing hypertension had a lower mean length of stay than male patients. In North India, the maximum patients suffering from D.M. (type-I and type-II) with co-existing hypertension consume butter, ghee- clarified butter. The study also revealed that the North Indian population least chooses rice bran oil. Secondly, cooking oil and physical activity play an essential role in the etiology of most chronic disorders like diabetes and contribute to the effective prevention of other diseases ²⁶. In conclusion, patients should advise adopting an effective and healthy lifestyle diet, together with physical activity, are the cornerstone in preventing diabetes with co-existing hypertension.
