Lower back pain can be irritating at best and debilitating at worse. For some, simple lifestyle changes may make a huge difference. I’m Miranda Savioli with your latest health news. A recent study found that nicotine dependence, alcohol abuse, obesity and depression were tied to an increased risk of lower back pain. For example, people with nicotine dependence were more than four times as likely as nonsmokers to develop lower back pain. This pain may increase medical costs, prevent people from working and lower quality of life. The authors of this study suggest that addressing these risk factors may help alleviate back pain.
