To assess relationships of total plasma cholesterol (TC) and triglycer
ide (TG) values to suicide, suicide ideation, and hospitalization for
psychiatric disease, we studied 220 children, ages 5 to 18 y, hospital
ized with affective, adjustment, disruptive, anxiety, schizophrenic, o
ther, and organic psychiatric disorders. The 135 male and 85 female pa
tients had higher TG values (p = 0.0001 and 0.0003, respectively) and
higher Quetelet Indices (p = 0.0001 and 0.003, respectively) than the
732 male and 316 female schoolchild controls; male patients had higher
TC values than male controls (p = 0.014). Substance abuse in patients
was an independent inverse determinant of TC value (p = 0.05); TG val
ue correlated positively with alcohol use (p less than or equal to 0.1
) and sustance abuse (p < 0.05). After covariance adjustment for age,
race, se?; and Quetelet, children having adjustment disorders with dep
ression had much lower covariance-adjusted TC value than control schoo
lchildren (3.91 versus 4.29 mmol/L, p = 0.003), whereas those with dis
ruptive behavior with oppositional defiant disorder had much higher ad
justed TC value (5.09 mmol/L, p = 0.0001). After covariance adjusting
for age, race, sex, Quetelet, cigarette smoking, alcohol use, and subs
tance abuse, children having adjustment disorders with concomitant dep
ression had the highest group suicide tendencies (attempts and ideatio
n) and the lowest covariance-adjusted TC value (4.03 mmol/L). Converse
ly, children having disruptive behavior with attention deficit hyperac
tivity disorder or disruptive behavior with oppositional defiant disor
der had 50% lower suicide index than those with adjustment disorders w
ith concomitant depression and higher adjusted TC levels (4.45 and 5.1
2 mmol/L, p 0.0003). Children with psychiatric hospitalizations have h
igh TG values, and those with adjustment disorders with concomitant de
pression have low TC values, which is positively associated with suici
de tendencies. We speculate that the associations between low TC level
, high TG level, suicide tendency, and hospitalization for psychiatric
disease do not reflect cause and effect but may be epiphenomena.
