Gunnell and Miller (1) identify strategies to prevent suicide attempts as an important public health measure to reduce premature mortality. We report a new association of suicide attempts with long term sequelae of childhood intrafamilial sexual abuse or incest.

Incest is not rare: 15% of US college students surveyed in 1991 reported an unwanted sexual experience in childhood (2), and a 1992 Scandinavian study showed that children suffering incest (intrafamilial abuse, by a trusted family member) experience more comorbidity (3). Recent US and European studies consistently show a similarly high proportion of children reporting unwanted sexual experiences (4),(5) . Despite this, identification of the sequelae of incest is not routinely taught in medical schools, even though epidemiological studies have begun to identify its long term consequences (6).

In 2009 the International Association of Incest Victims (AIVI3), initiated an epidemiological survey in France. IPSOS surveyed 931 individuals sampled from the general population and showed that 3% of the adult population have been subjected to incest.(7) A further IPSOS survey assessed the impact of incest on health and daily life, by comparing samples of those who had been subjected to incest (n=341 Face à l'inceste members) (Association International des Victimes de l'Inceste)with non abused individuals, using 12 questions derived from the Adverse Childhood Experience study (8) and the Trauma Screening Questionnaire (9). The internal consistency of the questionnaire as constructed was adequate (Cronbach's alpha 0.79).


A multivariate logistic regression was applied to the 1287 individuals of this survey. This showed 91% [95% CI, 87-95] of women and 76% [71-81] of men who answered "yes" (current or past) to three questions had experienced incest. These three questions relate to presence of:
- eating disorder (Q1),
- suicidal ideation and impulses (Q6),
- social phobia (afraid of others or of saying no) (Q9).

A "yes" response to all these three questions gave a positive predictive value of identifying past incest (PPV) of 91% for women and of 76% for men, and a negative predictive value of 82% for women and 97% for men. (In other words, when at least one response to the three questions is "no", 82% of women and 97% of men have not experienced incest.)

Responses to an additional 24 self-reported questions were gathered from the 341 respondents who had experienced incest. This revealed that chronic health symptoms related to incest remained unexplained for an average of 16 years until spontaneous disclosure (7).

The US based ACE study demonstrated a strong graduated relationship between the accumulation of adverse childhood experiences and multiple risk factors for public health problems.(10) Our French study is much smaller, however our results were unexpected and they appear significant. Suicidal ideation has not previously been systematically identified in relation to incest, but this triad of features (suicidal ideation, social phobia and eating disorder) represents a potentially simple and cheap clinical screening test to identify individuals at risk of mental health problems following experiences of incest, allowing appropriate intervention. Disclosure of incest may occur spontaneously, but unless physicians ask these three simple questions , the hidden risk is likely to last an average of 16 years.

To increase the chances of identifying suicide risk (and eating disorders) related to incest experiences we suggest that primary and emergency room carers use the presence of one of the triad as a prompt to ask these three simple questions (11). Early identification of this "triad" may be a valuable tool for screening for mental health trauma following incest.
