“…Early initiation of daily smoking was also a slightly greater risk factor for psychosis compared with late initiation of daily smoking even after adjusting for many potential confounders. This result is consistent with a previous study (21), which showed that earlier initiation of ever-smoking was associated with psychosis outcomes. It can be speculated that earlier onset of smoking could result in a greater cumulative dose of nicotine or other harmful byproducts from tobacco over time.…”

“…Thus, in keeping with previous studies of PEs, 3,9,18,19 we excluded respondents who (a) reported (1) schizophrenia/psychosis or (2) manic-depression/mania in response to the question “ What did the doctor say was causing (this/these) experiences?” ; and (b) those who ever took an antipsychotic medication for these symptoms. This resulted in the exclusion of 146 respondents (0.4% of all respondents), leaving 33,370 respondents for this study.…”

Association Between Psychotic Experiences and Subsequent Suicidal Thoughts and Behaviors

et al. 2017

IMPORTANCE Community-based studies have linked psychotic experiences (PEs) with increased risks of suicidal thoughts and behaviors (STBs). However, it is not known if these associations vary across the life-course or if mental disorders (antecedent to the STBs) contribute to these associations. OBJECTIVE To examine the temporal association between PEs and subsequent STBs across the life span as well as the influence of mental disorders (antecedent to the STBs) on these associations. DESIGN, SETTING, AND PARTICIPANTS A total of 33,370 adult respondents across 19 countries from the WHO World Mental Health (WMH) Surveys were assessed for PEs, STBs (ideation, plans, and attempts), and 21 DSM-IV mental disorders. Discrete-time survival analysis was used to investigate the associations of PEs with subsequent onsets of STBs. MAIN OUTCOMES AND MEASURES Prevalence and frequency of STBs with PEs, and odds ratios and 95%CIs. Results Of 33 370 included participants, among those with PEs (n = 2488), the lifetime prevalence (SE) of suicidal ideation, plans, and attempts was 28.5%(1.3), 10.8%(0.7), and 10.2%(0.7), respectively. Respondents with 1 or more PEs had 2-fold increased odds of subsequent STBs after adjusting for antecedent or intervening mental disorders (suicidal ideation: odds ratio, 2.2; 95%CI, 1.8-2.6; suicide plans: odds ratio, 2.1; 95%CI, 1.7-2.6; and suicide attempts: odds ratio, 1.9; 95%CI, 1.5-2.5). There were significant dose-response relationships of number of PE types with subsequent STBs that persisted after adjustment for mental disorders. Although PEs were significant predictors of subsequent STB onset across all life stages, associations were strongest in individuals 12 years and younger. After adjustment for antecedent mental disorders, the overall population attributable risk proportions for lifetime suicidal ideation, plans, and attempts associated with temporally prior PEs were 5.3%, 5.7%, and 4.8%, respectively. Conclusions PEs are associated with elevated odds of subsequent STBs across the life-course that cannot be explained by antecedent mental disorders. These results highlight the importance of including information about PEs in screening instruments designed to predict STBs.

“…Gurillo, Jauhar, Murray, and MacCabe (2015) identified that cigarette smoking was prevalent in young people with first episode psychosis, and that smokers developed psychosis at an earlier age than nonsmokers. Smoking can cause many negative life-threatening health outcomes and is widely recognized as a risk factor of comorbid physical health problems (Gurillo et al, 2015;McGrath et al, 2016). It also potentiates adverse pharmacotherapy effects because the nicotine consumed from smoking cigarettes interferes with the metabolism of antipsychotic medication (McGrath et al, 2016).…”

Psychiatric Ment Health Nurs

Background Registered nurses working in the area of mental health complete either a psychiatric/mental health or comprehensive/generalist nursing program, and their education preparation influences their physical health care nursing practices. The differences in educational preparation may be a contributory factor to nurses' delivery of physical health care to young people experiencing first episode psychosis. This paper addresses an identified gap in nursing practices related to physical health care of young mental health service users. Aim To examine the relationship between the educational preparation of nurses and attitudes, confidence level, perceived barriers and physical health care nursing practices. Method A cross-sectional survey was conducted in 2015 with 207 nurses using the modified Physical Health Attitude Scale for Mental Health Nurses (PHASe). Results Comprehensive/generalist prepared nurses were more likely to provide education on heart disease prevention and sexual health and support young people to stop cigarette smoking than psychiatric/mental health nurses. However, as the length of service progresses, the propensity for psychiatric/mental health nurses to be involve in smoking cessation increases. Implication for practice It is important to identify how nurses' educational preparation affects their nursing practices so as to address the gaps in their physical health literacy.
