Gait speed and sleep quality are the major health indexes to predict longevity and mortality. We measured gait speed and the quality of sleep and vision for cataract patients.
Consecutive 143 cataract patients (62 male at average ages of 76, 81 female at average ages of 77) indicated for surgery at age of 65 or older entered this study. Four meter gait speed starting from standing position was measured. Two surveys were administered using validated questionnaires: NEI-VFQ25 (Japanese version 1.4) and Pittsburg sleep quality. Normal range of sleep quality index (PSQI) was less than 5.5. Registered nurse interviewed each patient using standardized 14 item information collecting sheet of modefied Gordon functional health pattern for systemic evaluation.
The average of gait speed was 0.87 m/sec for male and 0.81 m/sec for female. The averages of VFQ25 score (compo 7) and PSQI were 68 and 4.7 for male and 61 and 6.0 for female, respectively. Regression analysis indicated VFQ25 score significantly correlated with PSQI (p< 0.005) and gait speed (P < 0.001). All of three indexes had significant gender difference. Gait speed was correlated with age (P < 0.001) and height (P < 0.001).
Gait speed and sleep quality in cataract patients was significantly correlated with the quality of vision. We will further explore the effectiveness of cataract surgery on health indexes.
