Провести анализ факторов риска хронизации боли в нижней части спины.Материал и методы. Проводилось проспективное исследование неспецифического болевого синдрома в нижней части спины 50 больных. Средний возраст больных составил 48,44 ± 15,1 года. Всем пациентам проведены неврологическое, нейропсихологическое и лабораторно-инструментальное исследования. Использовали диагностические опросники, в том числе опросник риска и хронизации боли the Keele STarT Back Screening Tool. Через 3 мес. от дебюта болевого синдрома всем пациентам проводилось телефонное интервью с целью выявления случаев сохраняющейся боли в спине и анализа ее причин.Результаты. Через 3 мес. после стационарного лечения 32% больных имели болевой синдром. Были выявлены следующие факторы риска хронизации болевого синдрома: высокая интенсивность боли, ее продолжительность, невропатический компонент, более старший возраст (р = 0,018), депрессия (р = 0,02), ожирение (р = 0,024).Заключение. Факторы риска хронической боли должны выделяться уже на стадии дебюта болевого синдрома.</p></abstract><trans-abstract xml:lang="en"><p>Low back pain is a leading cause of disability. Acute and chronic back pain affects 90% of the population.Objectives — to analyze the risk factors for chronic low back pain.Material and methods. A prospective study of nonspecific low back pain of 50 patients was carried out in the neurological department of the Emergency Clinic in Ufa. The exclusion criteria were discogenic compression radiculopathy, spinal stenosis, oncological pathology. By gender, men predominated. The average age of the patients was 48.44 ± 15.1 years. All patients underwent clinical neurological, neuropsychological and laboratory-instrumental studies. To study the nature of the pain syndrome, assess the cognitive and emotional spheres, we used diagnostic questionnaires, including the questionnaire of risk and chronicity of pain the Keele STarT Back Screening Tool. Three months after the onset of pain syndrome, all patients were interviewed by telephone in order to identify cases of persistent back pain and analyze its causes, for which a group of patients with chronic pain syndrome was singled out.Results. 32% of patients had pain syndrome 3 months after inpatient treatment. The following risk factors for chronic pain syndrome were identified: high intensity of pain, its duration, neuropathic component, older age (p = 0.018), depression (p = 0.02), obesity (p = 0.024).Conclusion. Risk factors for chronic low back pain are diverse, predictors of its development after episodes of acute pain, and should be identified as early as the onset of pain syndrome.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>острая боль</kwd><kwd>хроническая боль</kwd><kwd>факторы риска</kwd><kwd>тревога</kwd><kwd>депрессия</kwd><kwd>ожирение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>acute pain</kwd><kwd>chronic pain</kwd><kwd>risk factors</kwd><kwd>anxiety</kwd><kwd>depression</kwd><kwd>obesity</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Яхно Н.Н.
