Background; Obesity and musculoskeletal pain have significant correlation, but there is paucity of 
studies assessing the correlation of neck pain with obesity, in reference to gender or pregnancy. Aim 
of the study; The aim of this was to assess the impact of obesity on mechanical and inflammatory 
neck pain in young adult males, non- pregnant and pregnant females. Methods; Sixty patients, ages 
(twenty- thirty) with disease duration of three- six years complaining of mechanical and inflammatory 
neck pain. Thirty patients are obese and the other thirty patients are non- obese were recruited in the 
study. They were divided into four equal groups and subjected for measurement of CRP, leptin and 
cervical MRI. Patients with previous history of trauma or neck surgery were excluded from the study.
Results; The demographic data, clinical, laboratory and treatment characteristics of our study groups 
were presented in Table 1. The average age in group I to IV was 30.60±3.20, 30.46±2.94, 30.80±3.46 
and 30.60±3.66 years respectively, where age was not found to affect either the occurrence of obesity 
or neck pain in both the obese or non- obese individuals. As regards of the weight, BMI, and waist 
circumference obesity was found to be of high significance with the occurrence of neck pain; either 
the mechanical or the inflammatory (P ≤0.001) when compared to the non-obese, whereas obesity has 
no significant effect on both types of neck pain (P >0.05). Pain was found to be significantly 
correlated to obesity in mechanical neck pain but not in inflammatory type (P <0.05). CRP was 
significantly high in all groups (P ≤0.001). Leptin was significantly correlated to neck pain in the nonobese individuals (P <0.05). The positive MRI findings were significantly correlated to obesity in the 
inflammatory neck pain (P <0.05). Conclusion; Based on our results, we concluded that there is a 
positive relationship between obesity and neck pain when compared to the non-obese. However, 
gender or pregnancy was found not to affect the occurrence of obesity or neck pain, yet the pain was 
aggravated in obese as compared to non-obese, females compared to males and pregnant to nonpregnant.
