Self-reported disability in relation to mortality in rural Malawi: a longitudinal study of over 16 000 adults

Abstract

ObjectivesWe investigated whether self-reported disability was associated with mortality in adults in rural Malawi.SettingKaronga Health and Demographic Surveillance Site (HDSS), Northern Malawi.ParticipantsAll adults aged 18 and over residing in the HDSS were eligible to participate. During annual censuses in 2014 and 2015, participants were asked if they experienced difficulty in any of six functional domains and were classified as having disabilities if they reported ‘a lot of difficulty’ or ‘can’t do at all’ in any domain. Mortality data were collected until 31 December 2017. 16 748 participants (10 153 women and 6595 men) were followed up for a median of 29 months.Primary and secondary outcome measuresWe used Poisson regression to examine the relationship between disability and all-cause mortality adjusting for confounders. We assessed whether this relationship altered in the context of obesity, hypertension, diabetes or HIV. We also evaluated whether mortality from non-communicable diseases (NCD) was higher among people who had reported disability, as determined by verbal autopsy.ResultsAt baseline, 7.6% reported a disability and the overall adult mortality rate was 9.1/1000 person-years. Adults reporting disability had an all-cause mortality rate 2.70 times higher than those without, and mortality rate from NCDs 2.33 times higher than those without.ConclusionsSelf-reported disability predicts mortality at all adult ages in rural Malawi. Interventions to improve access to healthcare and other services are needed.

A focus on disability is necessary to achieve HIV epidemic control

“…53 A Malawian study reported that mortality rates from HIV were higher among people with disabilities, although without statistical significance. 54 Health system failures will make 95:95:95 targets hard to reach There are important negative consequences of these health systems failures for individuals, aside from the impact on mortality. People living with HIV and disabilities frequently experience worse quality of life, educational and social exclusion, and poorer mental health compared to those living with HIV alone.…”

Increased mortality risk for adults aged 25–44 years with long-term disability: A prospective cohort study with a 35-year follow-up of 30,080 individuals from 1984–2019 in the population-based HUNT study

“… 6 Thus far, only a few studies have investigated life expectancy among working-age adults with disability, and these have found increased risk for mortality. 5 , 14 , 15 , 16 , 17 However, apart from a Swedish study on young adults with mild intellectual disability, these studies were conducted in countries without a universal welfare-state model. Thus, inferring these findings to European welfare states may not be valid.…”
