As of 2015, the most important predictor of a person's mobility in the later years is one's health behavior, states the International Encyclopedia of Rehabilitation. Obesity, smoking, consuming alcohol and poor nutrition also significantly limit mobility as a person ages. Gender, age, diseases and socioeconomic status also have an impact.
Studies show that obese patients have reduced mobility and are more likely to experience problems engaging in their daily activities. Physically active patients are less likely to experience limited mobility later in life than those leading a sedentary lifestyle. Smokers are less likely to maintain lower body mobility and recover from impaired mobility than are nonsmokers. There are significant links between abstaining from alcohol, eating a balanced diet and maintaining mobility in later years, notes the International Encyclopedia of Rehabilitation.
