Importance<\/strong> — Self-harm behaviors including suicidal ideation and past attempts are frequent in bariatric surgery candidates. It is unclear, however, whether these behaviors are mitigated or aggravated by surgery.<\/p>\n

Objective<\/strong> — To compare the risk of self-harm behaviors before and after bariatric surgery.<\/p>\n

Design<\/strong> — Population-based self-matched longitudinal-cohort analysis.<\/p>\n

Setting<\/strong> — Ontario, Canada.<\/p>\n

Participants<\/strong> — Adults operated between April 1, 2006 and March 31, 2011 in Ontario.<\/p>\n

Intervention<\/strong> — Bariatric surgery.<\/p>\n

Outcome<\/strong> — Self-harm emergencies three years before and after surgery.<\/p>\n

Results<\/strong> — The cohort included 8,815 patients of whom most were women (81%), 35 years or older (80%), and treated with gastric bypass (98%). A total of 111 patients had 158 self-harm emergencies during follow-up. Overall, self-harm emergencies significantly increased after surgery (3.63\/1,000 patient-years) compared to before surgery period (2.33\/1,000 patient-years), equaling an incidence rate ratio (RR) of 1.54 (95% confidence interval [95% CI]=1.03-2.30; P=0.007). Self-harm emergencies after surgery were especially higher than before surgery among patients older than 35 years (RR=1.76; 95% CI=1.05-2.94), those with a low-income status (RR=2.09, 95%CI=1.20-3.65), and those living in rural areas (RR=6.49; 95% CI=1.42-29.63).
