- Context: Previous epidemiological, animal, and human cognitive neuroscience research suggests that maternal smoking during pregnancy (SDP) causes increased risk of substance use/problems in offspring.Objective: To determine the extent to which the association between SDP and offspring substance use/problems depends on confounded familial background factors by using a quasi-experimental design.Design: We used 2 separate samples from the United States and Sweden. The analyses prospectively predicted multiple indices of substance use and problems while controlling for statistical covariates and comparing differentially exposed siblings to minimize confounding.Setting: Offspring of a representative sample of women in the United States (sample 1) and the total Swedish population born during the period from January 1, 1983, to December 31, 1995 (sample 2).Patients or Other Participants: Adolescent offspring of the women in the National Longitudinal Survey of Youth 1979 (n = 6904) and all offspring born in Sweden during the 13-year period (n = 1,187,360).Main Outcome Measures: Self-reported adolescent alcohol, cigarette, and marijuana use and early onset (before 14 years of age) of each substance (sample 1) and substance-related convictions and hospitalizations for an alcohol- or other drug-related problem (sample 2).Results: The same pattern emerged for each index of substance use/problems across the 2 samples. At the population level, maternal SDP predicted every measure of offspring substance use/problems in both samples, ranging from adolescent alcohol use (hazard ratio [HR](moderate), 1.32 [95% CI, 1.22-1.43]; HR(high), 1.33 [1.17-1.53]) to a narcotics-related conviction (HR(moderate), 2.23 [2.14-2.31]; HR(high), 2.97 [2.86-3.09]). When comparing differentially exposed siblings to minimize genetic and environmental confounds, however, the association between SDP and each measure of substance use/problems was minimal and not statistically significant.Cocnlusions: The association between maternal SDP and offspring substance use/problems is likely due to familial background factors, not a causal influence, because siblings have similar rates of substance use and problems regardless of their specific exposure to SDP.

- Women commit 4-5% of all sexual crimes, but there is considerable uncertainty about associations with psychosis and substance abuse. We examined the prevalence of psychiatric hospitalization, psychotic disorders, and substance abuse in a nationwide sample of female sexual offenders. We obtained data from Swedish national registers for criminal convictions, hospital discharge diagnoses, and demographic and socioeconomic factors between 1988 and 2000, and merged them using unique identifiers. Convicted female sexual offenders (n = 93) were compared with all females convicted of non-sexual violent offences (n = 13,452) and a random sample of general population women (n = 20,597). Over 13 years, 36.6% of female sexual offenders had been admitted to psychiatric hospital and 7.5% been discharged with a diagnosis of a psychotic disorder. Compared to non-sexual violent offenders, there were no significant differences in the proportion diagnosed with psychosis or substance abuse. Compared to women in the general population, however, there was a significantly increased risk in sex offenders of psychiatric hospitalization (age-adjusted odds ratio [AOR] = 15.4; 95% CI: 10.0-23.7), being diagnosed with a psychotic disorder (AOR = 16.2; 95% CI: 7.2-36.4), and with substance use disorders (AOR = 22.6; 95% CI: 13.0-39.1). We conclude that the prevalence of psychotic and substance use disorders was not different between sexual offenders and other violent offenders, suggesting non-specificity of sexual offending in women. Nevertheless, substantially increased prevalences of psychiatric disorder, underline the importance of screening and assessment of female sexual and other violent offenders.
