الملخص EN

Background.

There are very few studies that had a sample size sufficient to explore the association between factors related to low back pain in a representative sample of the Iranian population.

Objective.

To examine the relationship between sociodemographic factors, smoking, obesity, and low back pain in Iranian people.

Methods.

We used Iranian adults respondents (n=25307) from the National Health Survey.

Adjusted odds ratios and 95% confidence intervals were estimated by using logistic regression.

Results.

The prevalence of low back pain was found in 29.3% of the studied sample.

High age, female sex, being married, obesity, low-economic index, being smoker, in a rural residence, and low educational attainment, all increased the odds of low back pain.

Conclusions.

Our findings add to the evidence on the importance of obesity in relation to low back pain.

These results can be used as a basis to reinforce health programs to prevent obesity.
