  • Seeing the similarities

    Open AccessMay Ci Van Schalkwyk, Duleeka Knipe et al.ARTICLEPLOS Global Public Health2026

    Fatal self-harm, more commonly referred to as suicide, is a serious public health problem affecting individuals and communities worldwide. Some products and services, such as paracetamol, bridges, and railways, are recognised as requiring regulatory or design interventions to prevent suicide. However, others with well-established associations with suicide, including alcohol, gambling products, pesticides, opioids and firearms, are often framed as…

  • Preventing suicide by restricting access to Highly Hazardous Pesticides (HHPs)

    Open AccessBruna Rubbo, Chao-Ying Tu et al.ARTICLEPLOS Global Public Health2025

    Suicide is a leading cause of death worldwide. A previous systematic review showed that regulations limiting access to highly hazardous pesticides (HHPs) were successful in preventing suicides. As the WHO strongly supports regulation of pesticides, we aimed to update and strengthen the evidence on the effectiveness of HHP bans. We conducted a systematic review by searching MEDLINE, Embase, and PsycINFO databases in March 2024 for manuscripts publ…

  • Intergenerational educational mobility and mental health

    Open AccessLucy Barrass, Maria Theresa Redaniel et al.ARTICLEPLOS Global Public Health2025

    Evidence suggests that associations between educational attainment and mental health may vary according to educational mobility (i.e., changes in educational attainment across generations). This evidence is largely limited to high-income countries. Using data from an ongoing birth cohort (Cebu Longitudinal Health and Nutrition Survey), we assessed the associations with mental health for both own educational attainment and intergenerational educat…

  • Trends of poisoning types in Sri Lanka

    Open AccessBruna Rubbo, Thilini Rajapakse et al.ARTICLEBMC Public Health2025

    The implementation of national bans of HHPs led to a reduction in number of admissions as well as CF due to pesticide poisoning in hospitals in Sri Lanka, with no evidence of substitution to other types of poisonings. The reversal of the upward trend in hospital admissions due to pesticide and medicinal poisonings suggests that the bans contributed to a reduction in admissions from these types of poisoning

  • Reflections on the trends of suicide in Sri Lanka, 1997–2022

    Open AccessPiumee Bandara, Prabath Wickrama et al.ARTICLEPLOS Global Public Health2024

    Despite reductions in suicide rates in Sri Lanka during the past decades, largely by introduction of national bans on highly hazardous pesticides, the country continues to record a higher than global average rate of suicide. With the changing availability of methods of suicide over time, we aimed to examine the age-standardized suicide rates in Sri Lanka by sex, age, and method between 1997 to 2022 using national police suicide data to identify t…

  • The Impact of the Covid-19 Pandemic and Lockdowns on Self-Poisoning and Suicide in Sri Lanka

    Open AccessThilini Rajapakse, Tharuka Silva et al.ARTICLEInternational Journal of…2023

    Evidence from high-income countries suggests that the impact of COVID-19 on suicide and self-harm has been limited, but evidence from low- and middle-income countries is lacking. Using data from a hospital-based self-poisoning register (January 2019-December 2021) and data from national records (2016-2021) of suicide in Sri Lanka, we aimed to assess the impact of the pandemic on both self-poisoning and suicide. We examined changes in admissions f…

  • Banning highly hazardous pesticides saves the lives of young people, particularly females, in low- and middle-income countries

    Open AccessLisa Schölin, Duleeka Knipe et al.ARTICLEBMC Public Health2023

    Pesticide self-poisoning is a public health problem mostly affecting low- and middle-income countries. In Sri Lanka, India and China suicide rates have reduced among young people, particularly females, following highly hazardous pesticides (HHP) bans. This success story requires attention to encourage more research on differential effects of HHP bans

  • Suicide and self-harm in low- and middle- income countries during the Covid-19 pandemic

    Open AccessDuleeka Knipe, Ann John et al.ARTICLEPLOS Global Public Health2022

    There is widespread concern over the potential impact of the COVID-19 pandemic on suicide and self-harm globally, particularly in low- and middle-income countries (LMIC) where the burden of these behaviours is greatest. We synthesised the evidence from the published literature on the impact of the pandemic on suicide and self-harm in LMIC. This review is nested within a living systematic review (PROSPERO ID CRD42020183326 ) that continuously iden…

  • Clinical and psychosocial factors associated with domestic violence among men and women in Kandy, Sri Lanka

    Open AccessPiumee Bandara, Andrew Page et al.ARTICLEPLOS Global Public Health2022

    Domestic violence (DV) is a violation of human rights with adverse intergenerational consequences on physical and mental health. Clinical and psychosocial correlates of DV have been documented internationally, but evidence from South Asia is limited, especially among men. This is a nested cross-sectional study of the control population (N = 856) of a large case-control study in Kandy, Sri Lanka. Multivariable logistic regression models were condu…

  • Barriers to help-seeking from healthcare professionals amongst women who experience domestic violence - a qualitative study in Sri Lanka

    Open AccessTharuka Silva, Thilini Chanchala Agampodi et al.ARTICLEBMC Public Health2022

    Barriers to help seeking for DV from HCPs exist at individual, healthcare level, and societal level. Community programs are needed to increase women's access to healthcare services and interventions should be implemented to develop effective, preventive, and supportive strategies at the healthcare system level

  • Sex education and self-poisoning in Sri Lanka

    Open AccessGrace Crowley, Piumee Bandara et al.ARTICLEBMC Public Health2022

    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

  • Is being a 'left-behind' child associated with an increased risk of self-poisoning in adulthood? Findings from a case–control study in Sri Lanka

    Open AccessDuleeka Knipe, Paul Moran et al.ARTICLEBMJ Global Health2021

    PURPOSE: The long-term consequences of parental emigration on offspring self-harm risk is unknown. METHODS: We investigated the association between experiencing parental emigration in childhood with hospital presentations for self-poisoning in adulthood using a hospital case-control study. Cases were adult self-poisoning patients (≥18 year olds) admitted to the medical toxicology ward Teaching Hospital Peradeniya, Sri Lanka. Sex and age frequency…

  • Regional variation in suicide rates in Sri Lanka between 1955 and 2011

    Open AccessDuleeka Knipe, Duleeka W Knipe et al.ARTICLEBMC Public Health2017

    The findings provide some support for the hypothesis that changes in access to pesticides contributed to the marked fluctuations in Sri Lanka's suicide rate, but the impact of other factors cannot be ruled out

  • Railway suicide in England and Wales 2000–2013

    Open AccessAnna Taylor, Anna K Taylor et al.ARTICLEBMC Public Health2016

    The continued rise in male railway suicide in England and Wales is concerning, particularly due to the high economic costs and psychological trauma associated with these deaths. The initiative's target of a 20% reduction in railway suicide is unlikely to be achieved

  • Suicide in Sri Lanka 1975–2012

    Open AccessDuleeka Knipe, Duleeka W Knipe et al.ARTICLEBMC Public Health2014

    The epidemiology of suicide in Sri Lanka has changed noticeably in the last 30 years. The introduction of pesticide regulations in Sri Lanka coincides with a reduction in suicide rates, with evidence of limited method substitution

  • A community-based cluster randomised trial of safe storage to reduce pesticide self-poisoning in rural Sri Lanka

    Open AccessMelissa Pearson, Flemming Konradsen et al.ARTICLEBMC Public Health2011

    This paper describes a large effectiveness study of a community intervention to reduce the burden of intentional poisoning in rural Sri Lanka. The study builds on a strong partnership between provincial health services, local and international researchers, and local communities. We discuss issues in relation to randomisation and contamination, engaging control villages, the intervention, and strategies to improve adherence
