The temperature fields caused by polymerization of the bone cement have been calculated by means of thermal-hydraulic codes used in nuclear reactor design; these codes have been adapted for use in vertebroplasty based on the conducted problem-oriented experiments.
We estimated associations between age 18 depression and either conduct problems ever or conduct problem trajectory classes using logistic regression models, with age 18 depression diagnosis as outcome and conduct problems ever or trajectory classes as predictors.
To compare the estimates obtained from the various conduct problem indicators with those for depression, the dichotomised MFQ scores were entered either on their own or together with conduct problems ever or conduct problem trajectory classes in logistic regression models.
Adjusted for these strong gender effects, both conduct problems ever and conduct problem trajectory classes remained significantly associated with risk for depression at age 18 (Table 1).
These were entered in logistic regression models with age 18 depression diagnosis as outcome and conduct problems ever and conduct problem trajectory classes as predictors.
This could be due to conduct problems among institutionalised adolescents.
Attention and conduct problems are important parts of school adjustment [ 13, 14].
A range of risk factors from early life measured prior to conduct problems were considered.
During adolescence, four concurrent conduct problem and substance use trajectory classes were identified (high conduct problems and high substance use, increasing conduct problems and increasing substance use, minimal conduct problems and increasing substance use, and minimal conduct problems and minimal substance use) using a parallel process growth mixture model.
The association between the early-life factors we studied (measured prior to measurement of conduct problems) and adolescent cannabis use was attenuated on adjustment for conduct problem trajectory.
Individuals on the adolescent-onset conduct problem path consumed more tobacco and illegal drugs and engaged more often in risky sexual behavior than individuals without childhood conduct problems.
