Table 4 Risk ratios for suicide attempts by severity of pain symptoms in different locations

From: The association of self-injurious behaviour and suicide attempts with recurrent idiopathic pain in adolescents: evidence from a population-based study

  M1: unadjusted M2: adjusted M3: fully-adjusted
One suicide attempt RR (95% CI) RR (95% CI) RR (95% CI)

 General pain (very often) 2.658 (1.748–4.043)*** 2.444 (1.618–2.692)*** 1.423 (0.931–2.175)

 Abdominal pain (very often) 2.314 (1.558–3.436)*** 1.933 (1.275–2.930)*** 1.023 (0.648–1.615)
Multiple suicide attempts RR (95% CI) RR (95% CI) RR (95% CI)
 General pain (sometimes) 2.028 (1.233–3.333)** 2.029 (1.217–3.384)** 1.267 (0.738–2.175)
 General pain (very often) 2.840 (1.539–5.240)*** 2.856 (1.561–5.225)*** 1.360 (0.743–2.487)

 Abdominal pain (very often) 5.795 (3.424–9.806)*** 4.468 (2.579–7.743)*** 1.986 (1.126–3.505)*
  1. Risk ratios from simultaneous estimates are expressed with respect to references categories for suicide attempts (no suicide attempt) and pain symptoms (no pain in the respective location) respectively; models on pain variables include missings (no response); Model 1: unadjusted, only adjusted for 116 clusters (schools); Model 2: adjusted for sociodemographic variables: gender, age, school type, and living situation at home; Model 3: further adjustment for all sub-scales of the YSR except for somatic complaints.
