The purpose of this study was to develop an integrated multi-disciplinary model for the causes of falling. Subjects for this study were 600 men and women over the age of 55 living in 13 different urban and suburban areas. Four different academic disciplines collaborated for this study including food and nutrition, nursing, health management, and physical education. Nutritional conditions, eating habits, food satisfaction, quality of sleep, excrement, daily activity ability, pain-discomfort, depression, life satisfaction, health conditions, health consultation frequency, social support, alcohol · tobacco consumption, leisure activities, loneliness, exercise, physical fitness, history of falling, and balance efficacy were evaluated via questionnaire. Statistical analysis was performed using the SAS 12.0 via regression analysis along with the stepwise collection (p<0.05) to develop the integrated multidisciplinary model, There was a statistical relation between five different factors and falling in the following order: a frequency of falling, physical fitness, diminished daily activity ability, pain or discomfort, and low social support. It is likely that subjects with strong social networks leave their home frequently to meet with friends or family and maintain social bonds. Thus, social life can be important not only psychologically, but also physically.
