Frailty among elderly

This dataset is of project titled Indian Network of population based Surveillance Platform for Influenza and other Respiratory viruses among Elderly (INSPIRE) collected from four site cohorts of community dwelling adults aged 60years or more residing in Ballabgarh, Kolkata, Pune and Chennai. There are three datasets:
1. baseline_data.dta- this dataset has the cohort characteristics and can be used to generate table 1 and supplementary table 1 of the manuscripts.
2. frailty_as_risk.dta- this dataset has quarterly Edmonton Frail Scale assessment survey data for four rounds combined with weekly surveillance data for ALRIs following the survey to assess the risk posed by frailty for causation of ALRI.
3. frailty_as_outcome.dta- this dataset has quarterly Edmonton Frail Scale assessment survey data for four rounds combined with weekly surveillance data for ALRIs episodes that took place before the frailty assessment to estimate the risk of ALRI on frailty.

本数据集源自题为《老年人群流感及其他呼吸道病毒社区监测平台印度网络（INSPIRE）》的研究项目，数据采集自巴拉加尔、加尔各答、浦那及金奈四个站点的60岁及以上社区居住成人队列。本数据集共包含三个子数据集：
1. baseline_data.dta：该数据集收录队列特征相关信息，可用于生成研究论文的表1及补充表1。
2. frailty_as_risk.dta：该数据集整合了四轮季度埃德蒙顿衰弱量表（Edmonton Frail Scale）评估调查数据，以及对应调查后发生的急性下呼吸道感染（Acute Lower Respiratory Tract Infection, ALRI）的每周监测数据，用于评估衰弱作为风险因素对急性下呼吸道感染发病的影响。
3. frailty_as_outcome.dta：该数据集整合了四轮季度埃德蒙顿衰弱量表评估调查数据，以及衰弱评估前发生的急性下呼吸道感染病例的每周监测数据，用于估算急性下呼吸道感染对衰弱发生的风险影响。
