title: Ethnic variation in the prevalence of depression and anxiety in primary care: a systematic review and meta-analysis.
abstract: Primary care plays a key role in the detection and management of depression and anxiety. At present it is not clear if the prevalence of depression and anxiety in primary care differs between migrants and ethnic minorities (MI) and natives and ethnic majorities (MA). A systematic review and a meta-analysis of studies comparing the prevalence of depression and anxiety in MI and MA in primary care were performed. Studies were identified by searching MEDLINE, PsychINFO, EMBASE and through hand-search. We included 25 studies, most of which had a relatively small sample size. Significant variations were found in the prevalence of anxiety and depression across studies. Pooled analyses were carried out for 23 studies, based on random-effects models. Pooled RR of depression and anxiety in MI were 1.21 (95% CI 1.04-1.40, p=0.012) and 1.01 (95% CI 0.76-1.32, p=0.971), with high heterogeneity (I²=87.2% and I²=73%). Differences in prevalence rates among studies can be accounted for by inclusion criteria, sampling methods, diagnostic instruments and study design. Further research on larger samples and with culturally adapted instruments is needed to estimate the prevalence of depression and anxiety in MI seeking help for these disorders.
