To investigate the prevalence and severity of radiographically detected hallux valgus (HV) as well as associated risk factors among Japanese residents of Miyagawa, a mountain village located in the center of Mie Prefecture.
The height, weight and body mass index (BMI) of 403 participants (male n = 135, female n = 268) recruited from among the residents of Miyagawa Village, Japan aged ≥65 years were measured, and baseline data, including age, sex and medical history were obtained from interviews and questionnaires. Knee osteoarthritis (KOA) was determined from radiographs of the feet and knees, and osteoporosis was determined by measuring bone mineral density. Hallux valgus, defined as angulation of the big toe at the first metatarsophalangeal joint of >20°, was classified as: mild (20°-30°), moderate (30°-40°) or severe (>40°). Risk factors for HV were calculated using multivariate logistic regression analysis that included age, sex, obesity (BMI ≥25), KOA, osteoporosis, Heberden's nodes and low back pain as variables.
The overall prevalence of definite radiographic HV was 22.8 % (184/806), and mild, moderate and severe HV was found in 66.3, 27.2 and 6.5 % of the participants, respectively. Hallux valgus was found in at least one foot in 120 (29.8 %) of the participants and the prevalence significantly differed between females with and without HV and KOA (odds ratios: 2.54 and 1.71, respectively).
The prevalence of definite radiographic HV was 29.8 %. Female sex and KOA were significantly associated with increased risk for radiographic HV.
调查位于三重县中部的山村宫川的日本居民中，通过影像学检测出的拇外翻（HV）的患病率和严重程度以及相关危险因素。
测量了从日本宫川村年龄≥65岁的居民中招募的403名参与者（男性n = 135，女性n = 268）的身高、体重和体重指数（BMI），并通过访谈和问卷获取包括年龄、性别和病史在内的基线数据。根据足部和膝盖的X线片确定膝关节骨关节炎（KOA），通过测量骨密度确定骨质疏松症。拇外翻定义为第一跖趾关节处大脚趾的角度>20°，分为：轻度（20°-30°）、中度（30°-40°）或重度（>40°）。使用多因素逻辑回归分析计算HV的危险因素，该分析将年龄、性别、肥胖（BMI≥2５）、KOA、骨质疏松症、赫伯登结节和腰痛作为变量。
明确的影像学HV的总体患病率为22.8%（184/806），轻度、中度和重度HV分别在66.3%、27.2%和6.5%的参与者中发现。120名（29.8%）参与者至少一只脚发现有拇外翻，有和没有HV及KOA的女性之间患病率有显著差异（优势比分别为：2.54和1.71）。
明确的影像学HV的患病率为29.8%。女性和KOA与影像学HV风险增加显著相关。
