Foot pain is a common complaint in adults. Increased BMI and fat mass have been linked only to foot pain prevalence. Therefore, a longitudinal study to examine the relationship between body composition and incident foot pain over 3 years was conducted.
Sixty-one community dwelling participants from a previous study of musculoskeletal health, who did not have foot pain at study inception in 2008, were invited to take part in this follow-up study in 2011. Current foot pain was determined using the Manchester Foot Pain and Disability Index, and body composition was measured using dual X-ray absorptiometry at study baseline.
Of the 51 respondents (84% response rate, 37 females and 14 males), there were 11 who developed foot pain. BMI ranged from underweight to morbidly obese (17-44 kg/m2), mean 27.0 ± 6.0 kg/m2. Incident foot pain was positively associated with both fat mass (odds ratio [OR] 1.11, 95% confidence interval [CI] 1.03-1.20) and fat-mass index (OR 1.28, 95% CI 1.04-1.57) in multivariate analysis.
Fat mass is a predictor of incident foot pain. This study supports the notion that incident foot pain in overweight individuals is associated with fat mass rather than body mass alone.
足部疼痛是成年人常见的抱怨。体重指数（BMI）和脂肪量的增加仅与足部疼痛的患病率有关。因此，进行了一项纵向研究，以检查 3 年内身体成分与新发足部疼痛之间的关系。
邀请了 61 名来自先前肌肉骨骼健康研究的社区居民参加本研究，他们在 2008 年研究开始时没有足部疼痛。在 2011 年的随访研究中，使用曼彻斯特足部疼痛和残疾指数确定当前的足部疼痛，使用双能 X 线吸收法在研究基线时测量身体成分。
在 51 名应答者（84%的应答率，37 名女性和 14 名男性）中，有 11 人出现了足部疼痛。BMI 从体重不足到肥胖（17-44 kg/m2），平均 27.0 ± 6.0 kg/m2。多变量分析显示，新发足部疼痛与脂肪量（比值比 [OR] 1.11，95%置信区间 [CI] 1.03-1.20）和脂肪量指数（OR 1.28，95%CI 1.04-1.57）呈正相关。
脂肪量是新发足部疼痛的预测因子。本研究支持超重个体新发足部疼痛与脂肪量而不仅仅是体重有关的观点。
