<unk>  is a very common condition, affecting around 50-80% of new mothers based on most sources. However, estimates of prevalence vary greatly in the literature, from 26-85%, depending on the criteria used. Precise rates are difficult to obtain given lack of standardized diagnostic criteria, inconsistency of presentation to medical care, and methodological limitations of retrospective reporting of symptoms. Evidence demonstrates that<unk>  exists across a variety of countries and cultures, however there is considerable heterogeneity in reported prevalence rates. For instance, reports of prevalence of<unk>  in the literature vary from 15% in Japan to 60% in Iran. Underreporting of symptoms due to cultural norms and expectations may be one explanation for this heterogeneity.
