Culturally tailored interventions of chronic disease targeting Korean Americans: a systematic review

Because little is known about promising interventions to prevent and control chronic disease in Korean Americans, we conducted a systematic literature review to investigate: (1) theoretical frameworks and strategies employed by interventions targeting Korean Americans; (2) cultural factors considered by these interventions; and (3) the extent of their success in engaging Korean participants and improving their health.

Following the PRISMA guidelines, PubMed, PsycInfo, and Web of Science were searched to identify primary research articles evaluating interventions to prevent or control chronic disease, tailored to Korean Americans, and published from 1980 through 2011. Of 238 articles identified, 21 articles describing16 unique intervention tests met inclusion criteria. These interventions targeted cancer (10), hypertension (2), diabetes (1), mental health (1), tobacco cessation (1), and general health (1).

All included studies were published since 2000, reflecting the relatively recent establishment of intervention research with Korean Americans. All 16 programs delivered linguistically appropriate messages and education. The 11 programs that realized significant intervention effects also provided or coordinated social support from culturally relevant and well-trained lay health workers, nurses, or family members during an intervention and/or follow-up period.

Culturally matched and linguistically appropriate messages and education may not be enough to prevent or control chronic disease among immigrant Korean Americans. Culturally sensitive and committed social support should be provided to catalyze behavioral changes and sustain the effect of the interventions.
