Mental status is significantly associated with low back pain: a survey-based cross-sectional study among Japanese women

Abstract

Abstract Objective Low back pain (LBP) is a highly prevalent condition that poses significant patient burden. This cross-sectional study identified factors associated with LBP occurrence and developed a strategy to identify, prevent, and reduce LBP-related burden on patient health. A web-based questionnaire-answering system was used to assess the potential effects of LBP on mental health, assessing five domains (physical features, demographics, lifestyle, diet, and mental status) conceptually associated with hie, a common disease state traditionally described in the Japanese culture as a chilly sensation. Results Of 1000 women, 354 had and 646 did not have LBP. The Chi test identified 21 factors, and subsequent multivariate logistic regression indicated eight factors significantly associated with LBP: age, history of physician consultation regarding anemia, history of analgesic agents, dietary limitations, nocturia, sauna use, hie, and fatigue. Furthermore, women with LBP exhibited a significantly lower body temperature (BT) in the axilla/on the forehead than women without LBP. LBP and hie are subjective and potentially affected by patient mental status. Stress reduces blood circulation, causing hypothermia and possibly worsening LBP. Therefore, mental-health support is important for patients with LBP to reduce physiological stress. Hyperthermia therapy, a traditionally prescribed intervention, is a potential intervention for future studies.
