The Effect of the Ideal Food Pyramid on Rheumatoid Arthritis

CRP was measured twice, at the beginning and at the end of the study, using the immunoturbidimetric method on the Cobos c701 (Roche Diagnostic- Basel, Switzerland) autoanalyzer.

Sedimentation rate will be studied twice, at the beginning and at the end of the study, using a Vision C ESR autoanalyzer (Shenzhen, China).

Total cholesterol will be measured spectrophotometrically on a Cobos c701 (Roche Diagnostic-Basel, Switzerland) autoanalyzer at the beginning of the study and at the end of 12 weeks.

LDL cholesterol will be measured spectrophotometrically on a Cobos c701 (Roche Diagnostic-Basel, Switzerland) autoanalyzer at the beginning of the study and at the end of 12 weeks.

DAS28-ESR includes the number of tender and swollen joints in 28 joints, the patient's estimate of their general health on the VAS, and the ESR.

• DAS28-ESR was calculated as 0.56 × √(Tender joint count) + 0.28 × √(Swollen joint count) + 0.7 × ln ESR + 0.014 × VAS-GH.

The score ranges from 0 to 9.4; values exceeding 5.1 are indicative of active disease and scores <3.2 indicate an inactive, well-controlled disease state.

DAS28-CRP includes the number of tender and swollen joints in 28 joints, the patient's estimate of their general health on the VAS, and the CRP.

• DAS28-CRP was calculated as 0.56 × √(Tender joint count) + 0.28 × √(Swollen joint count) + 0.36 × ln (CRP + 1) + 0.014 × VAS-GH + 0.96 The score ranges from 0 to 9.4; values exceeding 5.1 are indicative of active disease and scores <3.2 indicate an inactive, well-controlled disease state.

SDAI is calculated as the numerical sum of tender and swollen joint patient global assessment, physician global assessment, and C-reactive protein (CRP) level (mg/dL), with scores ranging from 0 to 86; A score of ≤ 3.3 is defined as remission, >3.3 to ≤ 11 indicates low disease activity, >11 and ≤ 26 indicates moderate disease activity, and high disease activity is defined by scores >40.

HAQ consists of 20 questions in 8 categories. Questions are scored from 0 to 3, with higher scores indicating worse functioning. Joint pain was measured using a horizontal visual analog scale (VAS) ranging from 0 to 10; higher scores indicate greater pain.

RAQoL consists of 30 questions, and participants are asked to indicate whether each question applies to them. Scores range from 0 to 30, with higher scores indicating lower quality of life.

SF-36 measures health-related quality of life using eight items: physical function, physical role difficulty, pain, general health perception, energy/vitality, social functioning, emotional role difficulty, and mental health. The SF-36 scales range from 0 to 100, with higher scores indicating better quality of life.

Body fat percentage is shown as a percentage (%). Measurement was made at the beginning and end of the study using a Tanita BC 418MA brand (bioelectrical impedance device [BIA]). For BIA measurement, individuals were asked not to do any heavy physical activity 24-48 hours before, not to consume alcohol 24 hours before, to come with at least 4 hours of fasting, not to consume too much liquid (water, tea, coffee) before the analysis (at least 4 hours) and not to carry any metal objects on them.

Body fat mass is calculated in kilograms. Measurement was made at the beginning and end of the study using a Tanita BC 418MA brand (bioelectrical impedance device [BIA]). For BIA measurement, individuals were asked not to do any heavy physical activity 24-48 hours before, not to consume alcohol 24 hours before, to come with at least 4 hours of fasting, not to consume too much liquid (water, tea, coffee) before the analysis (at least 4 hours) and not to carry any metal objects on them.

The formula "BMI=Weight (kg)/Height (m²)" was calculated.

The person to be measured is standing on their right side and the lowest rib bone is found and marked. The hip bone protrusion (cristailiac) is found on the hip and marked. The circumference passing through the middle of the two marked points is measured with a non-stretchable tape measure.

Hip circumference is measured with a non-stretchable tape measure at the widest part of the hip when viewed from the side while the individual is standing. It is written in centimeters.

Neck circumference is measured with a tape measure passing from the point where the neck and shoulders meet, just below the larynx.

Wrist circumference is measured with subjects in a seated position using a tension-gated tape measure placed over Lister's tubercle of the distal radius and the distal ulna.

The Jamar hand dynamometer, recommended by the American Association of Hand Therapists (AETD) and accepted as the gold standard for many studies with high validity and reliability, was used to measure hand grip strength. During the test, they were informed not to hold their breath and not to shake the dynamometer. In order to determine the dominant hand, participants were asked which hand they used while eating or writing. Each hand was measured 3 times and the average was taken, with the patients in a sitting position, shoulder adduction and neutral rotation, elbow 90 degrees flexed, forearm in midrotation and supported wrist in neutral.
