`Sleeplessness epidemic` affects 150 mn adults in developing world
Washington: A new study has revealed that levels of sleep problems in the developing world are far higher than previously thought and are approaching those seen in developed nations, linked to an increase in problems like depression and anxiety.
An estimated 150 million adults are suffering from sleep-related problems across the developing world, according to the first ever pan-African and Asian analysis of sleep problems, led by Warwick Medical School at the University of Warwick.
Warwick Medical School researchers have found a rate of 16.6 per cent of the population reporting insomnia and other severe sleep disturbances in the countries surveyed – close to the 20 per cent found in the general adult population in the West, according to nationwide surveys in Canada and the US.
The researchers, which also included academics from the INDEPTH Network in Ghana and the University of the Witwatersrand in South Africa, looked at the sleep quality of 24,434 women and 19,501 men aged 50 years and over in eight locations in rural populations in Ghana, Tanzania, South Africa, India, Bangladesh, Vietnam and Indonesia, and an urban area in Kenya.
They examined potential links between sleep problems and social demographics, quality of life, physical health and psychiatric conditions.
The strongest link was found between psychiatric conditions like depression and anxiety and sleep problems, mirroring trends seen in the developed world.
There was striking variation across the countries surveyed – Bangladesh, South Africa and Vietnam had extremely high levels of sleep problems, in some cases surpassing Western sleeplessness rates.
However India and Indonesia reported relatively low levels of severe sleep problems.
The research also found a higher prevalence of sleep problems in women and older age groups, consistent with patterns found in higher income countries.
“Our research shows the levels of sleep problems in the developing world are far higher than previously thought,” said Dr Saverio Stranges, the leading author of the manuscript at Warwick Medical School.
Bangladesh had the highest prevalence of sleep problems among the countries analysed – with a 43.9 per cent rate for women – more than twice the rate of developed countries and far higher than the 23.6 per cent seen in men. Bangladesh also saw very high patterns of anxiety and depression.
Vietnam too had very high rates of sleep problems – 37.6 per cent for women and 28.5 per cent for men.
Meanwhile in African countries, Tanzania, Kenya and Ghana saw rates of between 8.3 per cent and 12.7 per cent.
However South Africa had double the rate of the other African countries – 31.3 per cent for women and 27.2 per cent for men.
India and Indonesia both had very low prevalence of sleep issues – 6.5 per cent for Indian women and 4.3 per cent for Indian men. Indonesian men reported rates of sleep problems of 3.9 per cent and women had rates of 4.6 per cent.
The results are published in a study in the journal Sleep.
