Moderate or severe low back pain is associated with body mass index amongst community-dwelling older Australians
Methods: Cross-sectional study involving 16,439 Australians aged ≥70 years. Logistic regression was used to describe associations between the presence or absence of moderate or severe low back pain experienced on most days with BMI. Analyses were conducted separately for males and females, and controlled for age and depression at baseline.
Results: Of 14,155 pain question respondents, 11 % of males (n = 710/6475) and 18 % of females (n = 1391/7680) reported moderate or severe low back pain (total 15 %, n = 2101/14,155). Of those reporting moderate or severe low back pain (n = 2101), 55 % reported taking pain-relieving medication regularly, and 29 % reported that the pain regularly interfered with sleep, 37 % with walking, and 47 % with day to day activities. When age and depression were controlled for, there was a statistically significant (p < 0.001) association between moderate or severe low back pain and being overweight (females: odds ratio OR = 1.50, 95 % confidence interval CI = 1.27-1.76) or obese (males: OR = 2.23, 95 %CI = 1.77-2.80 and females: OR = 2.91, 95 %CI = 2.48-3.42).
Conclusion: Moderate or severe low back pain is common, has a significant impact, and is associated with either an overweight or obese BMI among community-dwelling Australians aged ≥70 years.
