長時間走動工作者足部疼痛評估及相關危險因子

目的：本研究調查長時間走動工作者足部疼痛常見的部位及比率，並進一步探討造成足部各部位疼痛之危險因子。方法：本研究採橫斷式研究設計，對象為台灣中部某醫院護送中心助理員49人。以問卷調查其基本資料、工作年資、身高、體重以及過去12個月內出現足部疼痛之情形；以電子計步器統計每人每日行走步數，乘以工作年資得到工作步年數，以代表長期走路所累積的風險；並以足底印模區分足型。統計分析使用t檢定、卡方檢定及邏輯迴歸，以比較各項危險因子在足部各部位疼痛之差異，並著重於足部各部位疼痛之影響因子。結果：此群工作者性別皆為女性，年齡平均為44.1±10.3歲，BMI值平均為23.5±3.3，工作年資平均為12.0±6.9年，每人每日行走步數平均為1.4±0.6萬步。有42人(85.7％)為正常足型，7人(14.3％)為非正常足型。足部疼痛的部位比率如下，足腹(77.6％)、足跟(67.3％)、腳趾(65.3％)、足弓(53.1％)。足部各部位疼痛與足型並無顯著相關。邏輯回歸結果顯示BMI值會影響足腹及足跟疼痛，而工作步年數會影響足跟疼痛。結論：需長時間走動的女性工作者，工作越久，累積步數越多，產生足跟疼痛的機會越高，而BMI值越高，會明顯增加此群工作者足腹及足跟疼痛的風險。若有足部疼痛，需適當的休息讓受傷的組織恢復，並維持正常體重，以減少足部疼痛的發生。

Purpose: The objectives of this study were to determine the prevalence of and the common parts of painful foot among long-term walking workers, and then to explore its risk factors. Method: A cross-sectional research method was adopted in this study. The sample was recruited from an escort center at a medical center in middle Taiwan. In total, 49 escort center assistants participated in the study. The variables of working year, body mass index (BMI), number of steps per day, foot type, and the data regarding painful foot were collected. A questionnaire including demographic data, working year, body height, body weight, and the part and occurrence of painful foot was distributed to each participant for obtaining related data. The number of steps per day were measured by electronic pedometer, and multiplied by working year to get personal working step-year which could represent the cumulative risk of long-term walking. The normal/abnormal foot type was determined by individual footprint. T-test, chi-square test, and logistic regression were applied to analyze data. Result: The participants were all female, with a mean age at 44.1±10.3 years. The mean BMI was 23.5±3.3. The average working time was 12.0±6.9 years. The average number of steps per day was 1.4±0.6 ten thousand steps. Foot type indicated that 85.7% were normal and 14.3% abnormal. The common parts of foot that often suffered from pain were forefoot (77.6%), heel (67.3%), toes (65.3%), and foot arch (53.1%). There was no significant correlation between each part of foot suffering from pain and foot type. The results using logistic regression showed that BMI had significant correlations with forefoot pain and heel pain. In addition, personal working step-year increased the risk of heel pain. Conclusion: Female workers who need long-term walking with longer working years and more cumulative walking steps had a higher risk of heel pain. Besides, BMI showed a significant effect on forefoot pain and heel pain for this group. Getting proper rest and keeping a normal body weight may be effective to reduce foot pain.
