고령여성의 BMI수준에 따른 일상생활체력의 비교

Physical fitness of daily living in elderly women with body mass index

  The purpose of this study was to examine the relationship between age and selected physical fitness item in low-, middle-, and high-BMI groups. We recruited 211 elderly women, aged 65~75 years, living independently in communities, The subjects completed 8 physical fitness tests related to activity of daily living (ADL), and were categorized into three groups using percentile rank of BMI: a) low BMI (＜19.3, n=66), (b) middle BMI (229~27.5, n=70), (c) high BMI (≥27.5, n=75). The 9 physical fitness tests were summarized as three domains: whole body locomotion, upper limb strength, and change of posture. Physical fitness domains were compared among the three groups with one-way ANOVA The major findings were the following: 1) upper limb strength was lower in the low-BMI group; 2) total physical fitness, whole body locomotion, and the changes of posture were lower in the high-BMI groups; 3) three physical domains and total physical fitness declined with age in all groups; and 4) the declines in total physical fitness and changed of posture were higher in the low-BMI group, and the declines in the same domains were lower in the middle- and high-BMI groups. These results suggest that low BMI, high BMI and advancing age are associated with decreases in physical fitness among elderly women.
