Abstract:
Objective:To explore the significance of proactive healthy living index(PHLI)to provide a reference for the elderly to maintain function through healthy daily life.Methods:The functional status of the elderly was defined based on gait speed and cognitive function.Logistic regression model was used to select the daily life indicators which could be the risk factors for the functional status, and a nomogram was graphed for its visualization.PHLI was formed according to the result of the nomogram.Receiver operating characteristic curve(ROC)was plotted according to the functional status of the elderly, and the cut-off value of PHLI was determined based on the principle of the maximum sum of sensitivity and specificity.Results:A total of 4 971 participants with an average age of (70.9±7.5)years were included in the cross-sectional study, of whom 2 649 cases(53.3%)maintained normal function.The Logistic regression analysis showed that the housework had the most significant effect on the functional status of the elderly, followed by positive psychology( OR=2.04, 1.92; both P<0.001), increasing the likelihood of maintaining normal function by 104% and 92%, respectively.Regular life patterns, adequate protein intake, sleep quality and so on also influenced functional status of the elderly(all P<0.05). The PHLI median score of the elderly was 7.3(5.9, 8.3)points.The area under the curve(AUC)was 0.70(95% CI: 0.68-0.71), and the cut off value of PHLI was 6.8 points. Conclusions:The PHLI is associated with the maintenance of functional capacity in the elderly, which can be applied as a simple tool to provide reference for old people to keep functional health through living a proactive healthy daily life.
