BACKGROUND: Globally, the population of older people is increasing and olderage associated with various health problems, including physical disability. Despitethe fact that the low and middle income countries (LMICs) are experiencing themost rapid population ageing, data regarding the Instrumental Activities DailyLiving (IADL) and Activities Daily Living (ADL) disability are still rare in thesecountries. This study aimed to measure the prevalence of IADL and ADL disabilityand to identify possible factors associated with IADL and ADL disability amongolder people aged 50 years and older in LMICs.METHODS: This study used secondary data from SAGE Longitudinal MultiCountry Study wave 1, which was conducted in 2007–2010 in six LMICs (China,Ghana, India, Mexico, Russian Federation and South Africa). A complete data from32,763 participants (l4,908 men and 17,855 women) were analysed. Multivariatelogistic regression models were performed to examine the association of sociodemographic factors (gender, age, education level, household wealth status, andresidence area) and number of chronic conditions, physical activity level, and BodyMass Index (BMI) on IADL and ADL disability.RESULTS: In all six countries, the prevalence IADL disability was higher than ADLdisability. And compared to men, generally women had higher prevalence ofdisabilities. The highest prevalence of IADL and ADL disabilities were in India(IADL: 78.9% and ADL: 55.6%) and the lowest were in China (IADL: 27.4% andADL 16.4%). Being women significantly associated with IADL and ADL disabilitiesin China, India, Ghana, and Mexico, but in Russian, it only associated with IADLdisability. Both disabilities were significant risk started from age 55 year in Indiaand Russian, while in Mexico it was only it was started from age 75. Chronicconditions in all SAGE countries were significantly associated with increasedlikelihood of both disabilities. Low physical activity level in most countries alsosignificantly associated with both disabilities.CONCLUSION: The prevalence of IADL and IADL in older people aged 50 year andolder were varies across the six LMICs. We found that countries had similaritiesand differences in term of factors associated with disabilities. The common riskfactors of IADL and ADL disability in all countries were people aged 75+, andpresence of chronic conditions. Additional common risk factors only for IADL werehad education less than 6 years, never schooled, and low physical activity level.Promoting health by focusing on prevention of chronic condition and raiseawareness of the importance of physical activity among older population willprevent incidence of disability among healthy older people and the disabled peoplefrom worsen condition.
