Correlation between pain frequency and the studied variables by
divided gender
To investigate the relationship between the amount of sulfur amino acids
and pain, spearman correlation was applied in Table 3 and 4. After
adjusting for potential confounding variable included total energy
intake, there was a significant relationship and weak correlation
between age, weight, WC, WHtR and BMI and severity and frequency of MPs
among women. Similarly, in men, there was just a positive and strong
relationship between age and severity of pain (R = 0.36; P = 0.01). No
positive relationship between any of the anthropometric indicators and
strength and frequency of pain was seen. In addition there was no
relationship between daily SAAs intake and severity of pain totally
(P> 0.05). Finally, the relationship between age, WC, WHtR
and BMI with pain intensity and age, WHtR, BMI and pain frequency was
statistically significant.
