Abstract | INTRODUCTION: Elevated body mass index
(BMI) or overweight and obesity are pan‐
demics. Lumbar disc herniation and sciatica
occur in every population and present se‐
vere socioeconomic consequences. How‐
ever, little is known regarding the role of
BMI with lumbar disc herniation and sciat‐
ica. As such, the following large‐scale study
addressed the association of BMI, in partic‐
ular overweight and obesity, with disc her‐
niation, its global lumbar involvement and
its implications with the development of
sciatica.
METHODS: A cross‐sectional study of 2,596
Southern Chinese (mean age: 42 years; 60%
females) was conducted assessing T2‐weighted MRI, environmental and lifestyle
factors, as well as clinical profiles of sciatica.
On imaging, the presence of disc
bulge/extrusion (DBE) and other spinal phe‐
notypes from L1‐S1 were assessed. A total
DBE (TDBE) Score of L1‐S1 was calculated.
Asian‐modified BMI values and categories
were obtained of each subject.
Results: DBE was noted in 46.3% of the sub‐
jects, mainly occurring at L4‐S1. The mean
TDBE score was 0.7. Historical prevalence of
sciatica was 44.6%, with 17.9% reporting
sciatica at the time of assessment. The
mean BMI was 22.9 kg/m2 (7.2% under‐
weight, 47.9% normal‐weight, 36.1% over‐
weight, 8.9% obese). TDBE Score sig‐
nificantly increased with elevated BMI cate‐
gories (p<0.001). Multivariate analyses not‐
ed that elevated BMI was significantly asso‐
ciated with DBE [normal‐weight (Ref); un‐
derweight OR: 0.71(0.49‐1.03); overweight
OR: 1.26(1.04‐1.52); obese OR: 1.78(1.30‐
2.44)]. TDBE score (OR: 1.36; 1.15‐1.60) and
obesity (OR: 1.68;1.25‐2.24) were signifi‐
cantly related with sciatica. Worse function‐
al and disability scores were associated with
sciatica (p<0.05). DISCUSSION: Based on the largest popula‐
tion‐based study to assess the role of BMI
and its association with disc herniation,
overweight and obesity significantly in‐
creased the likelihood of having lumbar
DBE, its global severity and the risk of de‐
veloping sciatica. |
