Participation in physical activity and back pain among an elderly population in South Asia

Abstract

Introduction

Globally, chronic back pain is one of the most commonly encountered medical conditions among an elderly population with significant bearings on health, functional mobility and general well-being.

Objective

To estimate the burden of chronic back pain and its association with physical activity (PA) among population aged 50 years and above in Bangladesh, India, Nepal, Pakistan and Sri Lanka.

Methods

Cross-sectional data on 8502 men and women aged 50 years and above were collected from the World Health Survey (2002). Three forms of PA were considered – vigorous physical activity (VPA), moderate physical activity (MPA) and walking. Odds ratios (ORs) of the association between self-reported back pain and VPA, MPA and walking were calculated by using generalized estimating equations.

Results

The prevalence of back pain was, respectively, 64.8%, 19.8%, 69.5%, 40.6% and 36.2% in Bangladesh, India, Nepal, Pakistan and Sri Lanka. No significant association between back pain and VPA was observed among men in any of the countries. In India, Pakistan and Sri Lanka, the odds of suffering from back pain were, respectively, 29%, 2.5 times and 59% higher among women who almost never took MPA. In India, taking MPA for few days a week and almost never was associated with, respectively, 38% (OR=1.38; 95% confidence interval [CI]=1.017–1.876) and 56% (OR=1.564; 95% CI=1.003–2.438) higher odds of reporting back pain. Walking almost never was also associated with, respectively, 83% (OR=1.829; 95% CI=1.14–2.934) and 2.9 times (OR=2.854; 95% CI=1.419–5.738) higher odds of reporting back pain among men in Nepal and Pakistan, respectively.

Conclusion

Though the relationship was not consistent across sex and countries, results indicate that inadequate or nonparticipation can substantially increase the likelihood of suffering from back pain among an elderly population in this region. Further research is needed to better understand this relationship and the potential of exercised-based strategies to prevent and treat back pain among elderly persons.
