Evaluation Of Stress Response In Diabetic Hypertensive Patients

In this research, we aimed to examine salivary cortisol changes in the cognitive stress response of patients with Hypertension + Diabetes Mellitus (HT+DM) and Hypertension (HT) and to determine the differences between them.

The research was conducted by solving an arithmetic task as a stress test in 62 patients with HT+DM and HT that are being treated in the outpatient clinic of Medical Pharmacology and Clinical Pharmacology Department at Istanbul University, Istanbul Medical Faculty Hospital.

About this study

In this study, saliva samples were taken for cortisol measurement, and patients were instructed to place the cotton piece in the salivette® tubes directly into their mouths without touching it with anything, hold it for 30-60 seconds, and then insert it back into the tubes in the same way, four times total, once before arithmetic stress and three times after stress, on Tuesdays, Wednesdays, and Thursdays between the hours of 12:00-16:00.

Salivary cortisol was measured using the electro-chemiluminescence immunoassay.

Treatment and study plan

First arithmetic problem solving

Behavioral

In a quiet environment, a white paper in A4 format was placed in front of the patient on the table, and the patients were asked to subtract the number 3 from 2907 for 100 seconds.

The researcher was standing in front of the patient and asks to make corrections by giving a warning whenever the patient made a mistake in the calculation.

Second arithmetic problem solving

Behavioral

In the same A4-sized white paper that was placed in front of each patient on a table, immediately after the first subtraction process, patients were asked to subtract 7 from 6828 for another 100 seconds.

When the patient made a calculating error, the researcher stood in front of the patient and asked them to make corrections by issuing a warning.

Third arithmetic problem solving

Behavioral

In the same A4-sized white paper that was placed in front of each patient on a table, immediately after the previous subtraction process, patients were asked to subtract 13 from 9561 for another 100 seconds.

When the patient made a calculating error, the researcher stood in front of the patient and asked them to make corrections by issuing a warning.

Fourth arithmetic problem solving

Behavioral

In the same A4-sized white paper that was placed in front of each patient on a table, immediately after the previous subtraction process, patients were asked to subtract 8 from 5113 for another 100 seconds.

When the patient made a calculating error, the researcher stood in front of the patient and asked them to make corrections by issuing a warning.

Fifth arithmetic problem solving

Behavioral

In the same A4-sized white paper that was placed in front of each patient on a table, immediately after the previous subtraction process, patients were asked to subtract 14 from 8318 for another 100 seconds.

When the patient made a calculating error, the researcher stood in front of the patient and asked them to make corrections by issuing a warning.

Sixth arithmetic problem solving

Behavioral

In the same A4-sized white paper that was placed in front of each patient on a table, immediately after the previous subtraction process, patients were asked to subtract 17 from 9994 for another 100 seconds.

When the patient made a calculating error, the researcher stood in front of the patient and asked them to make corrections by issuing a warning.
