Institutionalization in a nursing home restricts autonomy, most notably free will, free choice, and free action.
Decreased physical activity and fitness are predictive of disability and dependence (Rikli & Jones, 2013; Tak,
Kuiper, Chorus, & Hopman-Rock, 2014); however little is known about the impact of these factors on
institutionalization. Thus, this study aimed to analyze the impact of physical activity and fitness and on the
risk of elderly people without cognitive impairment become institutionalized.
This cross-sectional study involved 195 non-institutionalized (80.14.4yrs) and 186 institutionalized
(83.85.2yrs) participants. Cognitive impairment was assessed using Mini-Mental State Examination, physical
activity was assessed using the International Physical Activity Questionnaire, and measures of physical fitness
were determined by the Senior Fitness Test.
Results: Multivariate binary logistic analysis selected 4 main predictors of institutionalization in both genders.
The likelihood of becoming institutionalized increased by +18.6% for each additional year of age, while it
decreased by -24.8% by each fewer kg/m2 in BMI, by -0.9% for each additional meter performed in the
aerobic endurance test and by -2.0% for each additional 100MET-min/wk of physical activity expenditure
(p<0.05). Values ≤50th percentile (age ≥81yrs, BMI≥26.7kg/m2, aerobic endurance ≤367.6m, and physical
activity ≤693MET-min/wk) were computed using Receiver Operating Characteristics analysis as cut-offs
discriminating institutionalized from non-institutionalized elderly people.
The performance of physical activity, allied to an improvement in physical fitness (mainly BMI and aerobic
endurance) may prevent the institutionalization of elderly people without cognitive impairment only if they
are above the 50th percentile; the following is highly recommend: expending ≥693MET-min/wk on physical
activity, being ≤26.7kg/m2 on BMI, and being able to walk ≥367.6m in the aerobic endurance test, especially
above the age of 80 years. The discovery of this trigger justifies the development of physical activity programs
targeting the pointed cut-offs in old, and very old people.
