Type of intervention: CHW interventions focussed
on health-related outcomes.
Type of studies: randomised controlled trials (RCTs)
that compared a CHW arm against a control arm
receiving either usual care, no intervention, or
another intervention.
Target population: ethnic minority older adults
(50 years and over). Studies in which ethnic
minority older adults were at least 70% of the total
sample or in which the results were specified for
ethnic older adults. The minimum age was set to 50
because adults belonging to ethnic minority groups
often experience health problems at a younger age
than the majority population [15].
Type of CHW: paid or voluntary, carried out
functions associated with health care delivery,
involved in reaching and serving hard-to-reach and
underserved ethnic minorities, not a formally trained
health care professional, and not an extender of the
formal health care system.
Outcomes: outcomes related to health and delivery
of health care services.
Setting: studies conducted in Western countries.
Western countries were limited to Europe, the US,
Canada, Australia, and New Zealand because these
countries currently host a growing number of aging
adults belonging to ethnic minorities.
Time period: studies published in the last ten years.
The time period was limited to the last ten years to
include recently conducted studies
