About this study

Record cards of patients presenting with non specific low back pain between January 1st 2020 and December 23rd 2022 were analysed.

All included patients had undergone a full spine X-ray allowing to calculate the pelvic index (PI). Weight status was described in 4 categories, in-line with the WHO definitions; Underweight (boddy mass index (BMI)) < 18.5 kg/m²; normal weight BMI 18.5 - 24.9 kg/m² , overweight BMI 25 - 29.9 kg/m², and obesity BMI ≥ 30 kg/m². To identify people with increased BMI-values and central (abdominal) fat distribution, we used the waist circumference (WC). The cut-off points of waist measurement that are used are 102 cm and 88 cm for men and women respectively. A high sacral slope (SS) means a greater the lumbar curvature, which results in a dynamic back. Due to the correlation between SS and PI, people with high PI values generally have higher values of SS. Therefore types 1 and 2 have a low-grade PI and types 3 and 4 have a high-grade PI Analysis of 272 patient records, shows that the mean PI is significantly different in the group with a low WC compared with the group with a high WC. BMI and WC show a significant correlation with PI
