Normative Values for Londrina ADL Protocol in Healthy Individuals in Age Group of 40–60 Years among Indian Population: A Cross-Sectional Study

摘要

Background. Due to increase in the life expectancy and changes related to aging, it is important to assess ADL (activities of daily living) in older adults. However, there is no standardized protocol available to assess ADLs. Considering the limitations of the available tools, a new protocol named Londrina ADL protocol was developed for which normative values are unavailable in different ethnic groups. Objective. To develop the normative value and reference equation for the Londrina ADL protocol on the basis of anthropometric and demographic variables in healthy individuals in the age group of 40–60 years among the Indian population. Methods. This cross-sectional study was conducted with 282 healthy individuals of both the genders between the age group of 40 and 60 and they were divided into 2 groups: 40–49 and 50–60. Each subject was made to perform the Londrina ADL protocol twice with a 30?min interval between the two protocols. The protocol is composed of 5 activities and the best out of the 2 performances were recorded. Results. The mean time taken among 40–49 years by females is 3.50?±?0.50?min and by males is 3.73?±?0.43?min. The mean time taken among 50–60 years by females is 4.25?±?0.20?min and by males is 4.36?±?0.18?min. The reference equation to predict reference values for the Londrina ADL protocol was as follows: equation (1): Londrina ADL predicted?=?1.205?+?(0.054?×?age (years))?+?(0.001 × height (cm)); equation (2): Londrina ADL predicted?=?1.374?+?(0.054?×?age (years))?+?(?0.003?×?BMI). Conclusion. The reference equation for the time to complete the Londrina ADL protocol was based on age and BMI as independent variables and can be useful for predicting the performance of healthy individuals.
