Cigarette smoking dose-response and suicidal ideation among young people in Nepal: a cross-sectional study

Suicidal ideation, plan, and attempt among men who have sex with men in Nepal: Findings from a cross-sectional study

Men who have sex with men (MSM) are at increased risk for suicide, with a much higher prevalence of suicidality than the general population. While there is a growing interest in the identification of risk factors for suicidal behaviors globally, the understanding of the prevalence and risk factors for suicidal behaviors among MSM in the context of low- and middle-income countries is almost non-existent. Therefore, this study aimed to investigate suicidal ideation, plan, and attempts, and related factors among MSM in Nepal. A cross-sectional respondent driven survey was conducted on 250 MSM between October and December 2022. Bivariate and multivariable logistic regression was used to evaluate independent correlates of suicidal behaviors of MSM. Overall, the lifetime prevalence of suicidal ideation, plans, and attempts among MSM in this study were 42.4%, 31.2%, and 21.6%, respectively. MSM with depressive symptoms (aOR = 5.7, 95% CI = 2.4-14.1), advanced education (higher secondary and above; aOR = 2.9, 95% CI = 1.4-6.1), and smoking habit (aOR = 2.5, 95% CI = 1.2-5.3) were at increased risk for suicidal ideation. Similarly, those with depressive symptoms (aOR = 2.2, 95% CI = 1.1-4.8) and advanced education (aOR = 2.7, 95% CI = 1.2-5.7) were more likely to plan suicide, whereas young MSM were significantly more prone to attempting suicide (aOR = 2.7, 95% CI = 1.3-5.8). Interestingly, MSM with moderate to severe food insecurity were 2-3 times more likely to think about, plan, or attempt suicide (ideation: aOR = 3.5, 95% CI = 1.6-7.7; plan: aOR = 3.7, 95% CI = 1.6-8.3; attempt: aOR = 2.2, 95% CI = 1.1-4.6). The results suggest the importance of early assessment of suicidal behaviors among MSM and the need for tailored interventions to simultaneously address mental health problems and food insecurity to reduce suicide-related problems among Nepalese MSM.

Invasive Exploitation and the Multiplicative Hypothesis: Polyvictimization and Adolescent Depression Symptoms in Nepal

Adverse effects of childhood maltreatment experience and adolescent depression symptoms are theorized to be more profound for adolescents who have suffered multiple maltreatments (polyvictimization). New theoretical insights into the study of polyvictimization suggest that it must be studied using a multiplicative logic, particularly when maltreatment is characterized by invasive exploitation. This study, for the first time, examined the concept of invasive exploitation in the context of polyvictimization and its association with adolescent depression symptoms. The study used a random, three stage probability proportional to size (PPS) cluster sample of 565 mother-adolescent dyads in Kathmandu, Nepal, and also examined the protective effects of maternal empathy. We hypothesized that (a) singly, the empirical categories of maltreatment (neglect, physical abuse, and child sexual abuse) would associate positively with adolescent depressive symptoms and (b) main effects held constant, the interaction effects of a child sexual abuse X neglect and a child sexual abuse X physical abuse would be positive. Regression with clustering corrections found that neglect (B = 3.17, p < .01) and sexual abuse (B = 3.48, p < .05) positively associated with adolescent depression symptoms. Results support the multiplicative invasive exploitation polyvictimization hypothesis (child sexual abuse X neglect interaction; B = 6.14, p < .05). The positive neglect X sexual abuse interaction is consistent with the theory that sexual abuse is distinct as invasive exploitation, and demonstrates that the multiplicative hypothesis can be fruitfully applied to the study of polyvictimization. Interventions targeting polyvictims with experience of invasive exploitation and studies aiming to provide deeper insights into sexual abuse as invasive exploitation are needed.

Proposal for the Inclusion of Tobacco Use in Suicide Risk Scales: Results of a Meta-Analysis

There is an association between smoking and suicide, even though the direction and nature of this relationship remains controversial. This meta-analysis aimed to evaluate the association between smoking and suicidal behaviours (ideation, planning, suicide attempts, and death by suicide). On 24 August 2020, we searched the PubMed, Cochrane library, Scopus, Web of Science, TRIP, and SCIENCE DIRECT databases for relevant articles on this topic. Twenty prospective cohort studies involving 2,457,864 participants were included in this meta-analysis. Compared with never smokers, former and current smokers had an increased risk of death by suicide (relative risk [RR] = 1.31; 95% CI [1.13, 1.52] and RR = 2.41; 95% CI [2.08, 2.80], respectively), ideation (RR = 1.35; 95% CI [1.31, 1.39] and RR = 1.84; 95% CI [1.21, 2.78]), and attempted suicide (RR = 1.27; 95% CI [0.56, 2.87] and RR = 1.71; 95% CI [0.73, 3.97]). Moreover, compared to never smokers, current smoker women (RR = 2.51; 95% CI [2.06-3.04] had an increased risk of taking their own life (Q = 13,591.53; p < 0.001) than current smoker men (RR = 2.06; 95% CI [1.62-2.62]. Furthermore, smoking exposure (former and current smokers) was associated with a 1.74-fold increased risk (95% CI [1.54, 1.96]) of suicidal behaviour (death by suicide, ideation, planning, or attempts). Thus, because of the prospective relationship between smoking and suicidal behaviours, smoking should be included in suicide risk scales as a useful and easy item to evaluate suicide risk.

Suicidal Ideation Among Medical Students in Dammam, Saudi Arabia

Background: Medical students are at high risk of suicidal ideation. Aim: We aimed to obtain information on suicidal ideation among medical students in Dammam located in the Eastern Province of Saudi Arabia. Method: This cross-sectional study was conducted at the College of Medicine affiliated with Imam Abdulrahman Bin Faisal University in the Eastern Province of Saudi Arabia. Suicidal ideation in the past 12 months was assessed based on responses to four questions in the depression subscale of the General Health Questionnaire 28 (GHQ-28). In addition, data were collected to examine the association of suicidal ideation with various factors. Results: We found that 1 in 3 medical students in the study had suicidal ideation in the past 12 months, while around 40% had lifetime suicidal ideation. Suicidal ideation was associated with feelings of parental neglect, history of physical abuse, and dissatisfaction with academic performance. Limitations: The cross-sectional nature of this study limits its ability to determine causality regarding suicidal ideation. Conclusion: These rates are considerably high when compared with rates from studies in other countries around the world. This study provides a reference in the field of suicidology for this region of Saudi Arabia.
