Risk Factors and Disability Associated with Low Back XXXX in Older Adults in Low- and Middle-Income Countries. Results from the WHO Study on Global AGEing and Adult Health ( @entity12337 ).

@entity615 @entity12337 @entity158
BACKGROUND: Back @entity158 is a common disabling chronic condition that burdens individuals, families and societies. Epidemiological evidence, mainly from high-income countries, shows positive association between @entity615 prevalence and older age. There is an urgent need for accurate epidemiological data on @entity615 in adult populations in low- and middle-income countries (LMICs) where populations are ageing rapidly. The objectives of this study are to: measure the prevalence of @entity615 ; identify risk factors and determinants associated with @entity615 , and describe association between @entity615 and disability in adults aged 50 years and older, in six LMICs from different regions of the world. The findings provide insights into country-level differences in self-reported @entity615 and disability in a group of socially, culturally, economically and geographically diverse LMICs. METHODS: Standardized national survey data collected from adults (50 years and older) participating in the World Health Organization (WHO) Study on global AGEing and adult health ( @entity12337 ) were analysed. The weighted sample (n = 30, 146) comprised respondents in China, Ghana, India, Mexico, South Africa and the Russian Federation. Multivariable regressions describe factors associated with @entity615 prevalence and intensity, and @entity615 as a determinant of disability. RESULTS: Prevalence was highest in the Russian Federation (56%) and lowest in China (22%). In the pooled multi-country analyses, female sex, lower education, lower wealth and multiple chronic morbidities were significant in association with @entity615 (p<0.01). About 8% of respondents reported that they experienced intense @entity615 in the previous month. CONCLUSIONS: Evidence on @entity615 and its impact on disability is needed in developing countries so that governments can invest in cost-effective education and rehabilitation to reduce the growing social and economic burden imposed by this disabling condition.
