There is no doubt that nutritional status may be a major factor in determining the level of physical functional fitness, cognitive functioning, and quality of life.
Pain is the primary symptom of knee OA and people with higher levels of pain have lower levels of physical function, greater functional decline and reduced quality of life [ 6].
where i denotes a level-one unit, namely the respondent; j denotes a level-two unit, namely a county-level unit; y ij is the score of physical functional status or depressive symptoms; π ij is the probability of self-rated health as "not-good"; and μ 0j denotes the residual of the level-two unit, representing the area effect.
The present study identified that education level was inversely associated with prevalence of physical functional limitation among Japanese men and women.
Low education level was associated with the higher prevalence of physical functional limitations for both genders.
Low educational levels has been associated with cognitive impairment [ 10], unhealthy behaviors [ 9], and history of falling [ 11], which lead a hypothesis that unequal prevalence of physical functional limitation by education level could exist in Japan.
The severity of the SCI depends upon the extent as well as the level of injury resulting in barriers to self dependence in terms of physical, functional, psychosocial and economic status.
Patients are less likely to achieve the requisite level of physical functioning to permit discharge home if they have poor functional reserve to begin with.
No prospective information was obtained at baseline, however, which indicated levels of physical or functional impairment, and we were therefore unable to examine this hypothesis in more detail.
Examples are low levels of physical activity, functional restrictions due to diabetes or another medical condition, medical nonadherence, inadequate treatment secondary to poor appointment attendance, and the exacerbation of another medical condition.
