Abstract:
Neck pain is a very common public health problem worldwide and is allied with both work absenteeism and disability in daily life. Chronic neck pain is common in the adult population. The aim of this study was to investigate the relationship between neck pain intensity and the anthropometric measurements of patients’ and chronic neck pain. A cross sectional study was conducted on 285chronic neck pain patients aged between 20 and 69 years attending the rheumatology clinic at the Colombo South Teaching Hospital. Data were collected by using an interviewer administered questionnaire. Pain Intensity (PI) was measured by a visual analog scale 0mm (no pain) to 100mm (worst possible pain).It was categorized as mild (125), moderate (26-50), severe (51-75) and worst possible pain (76-100).Standing height (StHt), weight (Wt), sitting height (SiHt), neck length (NL), neck circumference (NC) were measured. Body mass index (BMI) and relative neck length (RNL) was calculated. The mean age of the patients was 52.79 ± 12.15 and 224 (78.5%) were females. Mean PI was 75.03±11.991. The mean PI in male and female were74.69±11.246 and 73.55±11.977 respectively and not significantly different (P = 0.497). The mean BMI ± SD was 24.38 ± 4.0404 and 181 (63.5%) were overweight or obese from which 169 (93.4%) had severe or worst possible pain. The mean BMI of patients with ‘moderate pain’ (22.75±4.2958) was not significantly different from mean BMI of ‘severe and worst possible pain’ (24.525±3.9979). However, there was a significant (P = 0.031), low positive (r =.146) correlation between PI and BMI.The mean SHt of male and female were 83.87±4.670 cm and 79.13±4.621 cm respectively. A statistically significant (P = 0.034), low positive correlation (r = 0.161) was found, between PI and SiHt in female and there was no statistically significant, correlation between PI and SiHt in male (P = 0.789, r = 0.041). Male and female together, StHt was not associated with PI. RNL was associated with PI in both male and female. The mean NC of male and female were 159.79±15.858mm and female 142.81±16.88mm. The mean NL were 363.15±37.064mm in male and 339.14±29.708mm in female. NC and NL were not associated with PI in both sexes. This study concludes PI is associated with being overweight and obese. Sitting height of the women are significantly associated with PI but no association in male with chronic neck pain.
