Abstract:
Suicidal thoughts and behaviors in borderline personality disorder are common, but their frequency and forms
vary across cultures, genders, and regions. Inequity-focused systematized review using the PROGRESS-Plus
framework. Adult studies were included if suicidality was reported by at least one equity domain. We extracted
simple proportions and risk differences, used vote-counting by direction of effect, and summarized medians
across subgroups (gender, gender identity, ethnicity, migration, region, urbanicity). Recent studies indicate
lifetime suicidal ideation ~70–85%, suicide attempts ~40–60%, and suicide deaths ~3–10%. Women show
higher attempt prevalence than men (≈55% vs 35–45%), whereas men have higher death proportions (≈5–9% vs
3–5%). Sexual and gender minority groups report elevated attempts (≈60–70% vs 40–55% in cisgender groups).
Cultural/ethnic minority status and migration are associated with +10–20% attempts and more emergency
presentations. Regional comparisons show 20–30% variation in attempt prevalence and differences in methods
and service use; urban settings report ~10–20% more emergency presentations than rural. Measurement
heterogeneity and under-representation of low- and middle-income regions limit precision; disparities are
consistent in direction but vary in magnitude, underscoring the need for standardized, disaggregated reporting
and culturally adapted prevention.
