Blue whales in the Northern Indian Ocean are a morphologically and acoustically distinct population restricted to these waters. Off Sri Lanka a portion of the population concentrates near shore where they are exposed to a range of anthropogenic threats. We review available data to determine anthropogenic threats/stressors faced by this population and assign subjective rankings for the population-level severity of each threat/stressor based on severity, scope, and immediacy. With the cessation of direct illegal catches on this population in the late 1960s, we ranked ship strike as the most important population-level threat. Incidental catch, which includes entanglement and bycatch, is also important as it can result in death. Other less important stressors that may negatively impact this population include threats resulting from oil and gas development and pollution. However, some stressors can have a long-term cumulative impact that is difficult to assess. The most important research needed for the conservation of these whales is to obtain an estimate of the size of the population using photo-identification methods.

Abstract Background Self-harm and suicide are important causes of morbidity and mortality in Sri Lanka, but our understanding of these behaviours is limited. Qualitative studies have implicated familial and societal expectations around sex and relationships. We conducted an explorative analysis using case-control data to investigate the association between sex education and self-poisoning in Sri Lanka. Methods Cases (N=298) were self-poisoning inpatients on a toxicology ward, Teaching Hospital Peradeniya. Controls (N=500) were sex and age frequency matched to cases and were outpatients/visitors to the same hospital. Participants were asked whether they had received sex education, and to rate the quality and usefulness of any sex education received. Logistic regression models adjusted for age, sex, and religion quantified the association between receipt, quality and usefulness of sex education and self-poisoning. We tested whether the associations differed by sex. Results Roughly 1-in-3 cases and 1-in-5 controls reported having not received sex education. Individuals who did not receive sex education were nearly twice as likely to have self-poisoned than those who did (OR 1.68 (95% CI 1.11-2.55)). Those who reported the sex education they received as not useful were more likely to have self-poisoned compared to those who reported it useful (OR 1.95 (95% CI 1.04-3.65)). We found no evidence of an association between self-poisoning and the self-rated quality of sex education, or that associations differed by participant sex. Conclusion As sex education is potentially modifiable at the population-level, further research should aim to explore this association in more depth, using qualitative methods and validated measurement tools.

Background: Suicidal ideation can often lead to suicide attempts and completed suicide. Studies have shown that Sri Lanka has one of the highest rates of suicide in the world but so far no studies have looked at prevalence of suicidal ideation in a general population in Sri Lanka. Aims: We wanted to determine the prevalence of suicidal ideation by randomly selecting six Divisional Secretariats (Dss) out of 17 in one district. This district is known to have higher than national average rates of suicide. Methods: 808 participants were interviewed using Sinhala versions of GHQ-30 and Beck’s Scale for Suicidal Ideation. Of these, 387 (48%) were males, and 421 (52%) were female. Results: On Beck’s Scale for Suicidal Ideation, 29 individuals (4%) had active suicidal ideation and 23 (3%) had passive suicidal ideation. The active suicidal ideators were young, physically ill and had higher levels of helplessness and hopelessness. Conclusions: The prevalence of suicidal ideation in Sri Lanka is lower than reported from the West and yet suicide rates are higher. Further work must explore cultural and religious factors.

Summary: The Indian subcontinent comprises eight countries (India, Pakistan, Bangladesh, Nepal, Sri Lanka, Afghanistan, Bhutan, and the Maldives) and a collective population of more than 1.3 billion people. 10% of the world's suicides (more than 100,000 people) take place in just three of these countries, viz. India, Sri Lanka, and Pakistan. There is very little information on suicides from the other four countries. Some differences from suicides in Western countries include the high use of organophosphate insecticides, larger numbers of married women, fewer elderly subjects, and interpersonal relationship problems and life events as important causative factors. There is need for more and better information regarding suicide in the countries of the Indian subcontinent. In particular, studies must address culture-specific risk factors associated with suicide in these countries. The prevention of this important public health problem in an area of the world with myriad socio-economic problems, meager resources, and stigmatization of mental illness poses a formidable challenge to mental health professionals, policy makers, and governments of these countries.
