Item The associations of childhood adversities and mental disorders with suicidal thoughts and behaviors - Results from the World Mental Health International College Student Initiative(Elsevier B V, 2025-08-01) Mortier P; Yang X; Altwaijri YA; Holdcraft JA; Lee S; Sampson NA; Albor Y; Alhadi AN; Alonso J; Al-Saud NK; Andersson C; Atwoli L; Auerbach RP; Muaka CA; Báez-Mansur PM; Ballester L; Bantjes J; Baumeister H; Bendtsen M; Benjet C; Berman AH; Bruffaerts R; Carrasco P; Chan SCN; Cohut I; Covarrubias Díaz Couder MA; Crockett MA; Cuijpers P; David OA; Dong D; Ebert DD; Gaete J; Felez-Nobrega M; García Forero C; Gili M; Gutiérrez-García RA; Haro JM; Hasking P; Hunt X; Husky MM; Jaguga F; Jansen L; Langer ÁI; Liu Y; Mac-Ginty S; Martínez V; Mason A; Mathai M; McLafferty M; Miranda-Mendizabal A; Murray EK; Musyoka CM; O'Neill SM; Papasteri CC; Piqueras JA; Popescu CA; Rapsey C; Robinson K; Rodriguez-Jimenez T; Scarf D; Siu O-L; Stein DJ; Struijs SY; Tomoiaga CT; Valdés-García KP; Vereecke S; Vigo DV; Wang AY; Wong SYS; Kessler RC; World Mental Health International College Student collaboratorsObjective: To investigate the associations of demographic variables, childhood adversities (CAs), and mental disorders (MDx) with onset, transition, and persistence of suicidal thoughts and behaviors (STB) among first-year university students. Method: Poisson regression models within a discrete-time survival framework were constructed using web-based self-report survey data from 72,288 incoming university students across 18 countries (response rate=20.9%; median age=19 years, 57.9% female, 1.4% transgender, 21.0% non-heterosexual). These models examined the associations of four demographic variables, five CAs, and eight MDx with STB outcomes. Results: Lifetime prevalence of suicidal ideation, plans, and attempts was 47.0%, 26.0%, and 9.6%, respectively; 12-month estimates were 30.6%, 14.0%, and 2.3%. In unadjusted analyses, associations were strongest between lifetime onset of suicidal ideation and CAs (RR range 4.4–7.0), particularly parental psychopathology (relative risk [RR]=7.0 [95% CI 6.5–7.7]), followed by MDx (RR range 1.3–3.0). Of the demographic subgroups, transgender students had highest risk of STB (lifetime ideation onset RR=2.4 [2.3–2.6]; ideation-to-attempt transition RR=1.5 [1.3–1.8]). In fully adjusted models, strongest predictors of lifetime ideation onset were emotional abuse (RR=2.1 [1.9–2.2]), major depressive disorder (RR=2.0 [1.9–2.1]), and bipolar disorder (RR=1.8 [1.6–2.0]). Ideation-to-attempt transition remained most strongly associated with panic disorder (RR=1.5 [1.3–1.7]), bipolar disorder (RR=1.4 [1.2–1.7]), and sexual abuse (RR=1.4 [1.2–1.7]). Most predictors were significantly but weakly associated with persistence of ideation and plan, while only physical abuse remained associated with repeated suicide attempts (RR=1.3 [1.0–1.8]). Conclusion: CAs and MDx are strong predictors of both onset of and transition within the STB spectrum, underscoring the importance of implementing early-life prevention interventions.Item Development and evaluation of a predictive algorithm and telehealth intervention to reduce suicidal behavior among university students.(Cambridge University Press, 2024-04-01) Hasking PA; Robinson K; McEvoy P; Melvin G; Bruffaerts R; Boyes ME; Auerbach RP; Hendrie D; Nock MK; Preece DA; Rees C; Kessler RCBACKGROUND: Suicidal behaviors are prevalent among college students; however, students remain reluctant to seek support. We developed a predictive algorithm to identify students at risk of suicidal behavior and used telehealth to reduce subsequent risk. METHODS: Data come from several waves of a prospective cohort study (2016-2022) of college students (n = 5454). All first-year students were invited to participate as volunteers. (Response rates range: 16.00-19.93%). A stepped-care approach was implemented: (i) all students received a comprehensive list of services; (ii) those reporting past 12-month suicidal ideation were directed to a safety planning application; (iii) those identified as high risk of suicidal behavior by the algorithm or reporting 12-month suicide attempt were contacted via telephone within 24-h of survey completion. Intervention focused on support/safety-planning, and referral to services for this high-risk group. RESULTS: 5454 students ranging in age from 17-36 (s.d. = 5.346) participated; 65% female. The algorithm identified 77% of students reporting subsequent suicidal behavior in the top 15% of predicted probabilities (Sensitivity = 26.26 [95% CI 17.93-36.07]; Specificity = 97.46 [95% CI 96.21-98.38], PPV = 53.06 [95% CI 40.16-65.56]; AUC range: 0.895 [95% CIs 0.872-0.917] to 0.966 [95% CIs 0.939-0.994]). High-risk students in the Intervention Cohort showed a 41.7% reduction in probability of suicidal behavior at 12-month follow-up compared to high-risk students in the Control Cohort. CONCLUSIONS: Predictive risk algorithms embedded into universal screening, coupled with telehealth intervention, offer significant potential as a suicide prevention approach for students.Item Dialogic Approach to Teaching and Learning Environmental Management Accounting (EMA) in Tertiary Education(Taylor and Francis Group, 2023-11-20) Raja-Adzrin R-A; Othman R; Othman N; Mohd-Tahir HHB; Amiruddin-Othman AMThis study focuses on an environmental management accounting (EMA) course and explores how a pedagogical project, incorporating dialogic environmental and sustainability elements, transforms students' perspectives and educational experiences. The findings support the shift towards a dialogic approach to enhance the educational experiences of tertiary accounting students, encouraging them to think creatively and critically and to aspire to become engaged citizens. Students' experiences with the dialogic approach were generally positive, with noticeable development of soft skills. They also expressed their aspirations as to what the future of accounting education should look like, including the structure, content, and delivery. However, both educators and some students reported a loss of control compared to the previously favoured monologic approach to teaching and learning. Lessons learned from this study highlight the potential of pedagogical interventions to improve teaching and learning outcomes, fostering a cycle of mutual learning that generates actions based on dialogical encounters.Item Secondary School Students and Caffeine: Consumption Habits, Motivations, and Experiences.(MDPI (Basel, Switzerland), 2023-02-17) Turner S; Ali A; Wham C; Rutherfurd-Markwick K; Cornelis M; Tauler PAdolescents may be particularly vulnerable to the effects of caffeine due to a lack of tolerance, their small size, changing brain physiology, and increasing independence. Concerns about adolescent caffeine consumption relate to potentially serious physiological and psychological effects following consumption. Motivations driving caffeine intake are not well understood among adolescents but are important to understand to reduce harmful behavioural patterns. This study explored caffeine consumption habits (sources, amount, frequency) of New Zealand adolescents; and factors motivating caffeine consumption and avoidance. The previously validated caffeine consumption habits questionnaire (CaffCo) was completed by 216 participants (15-18 years), with most (94.9%) consuming at least one caffeinated product daily. Chocolate, coffee, tea, and kola drinks were the most consumed sources. The median caffeine intake was 68 mg·day-1. Gender (boy) and being employed influenced the source, but not the quantity of caffeine consumed. One-fifth (21.2%) of adolescents consumed more than the recommended European Food Safety Authority (EFSA) safe level (3 mg·kg-1·day-1). Taste, energy, and temperature were the main motivators for consumption, and increased energy, excitement, restlessness, and sleep disturbances were reported effects following caffeine consumption. This study provides information on caffeinated product consumption among New Zealand adolescents, some of whom consumed caffeine above the EFSA safe level. Public health initiatives directed at adolescents may be important to reduce potential caffeine-related harm.Item Whole-genome sequencing and ad hoc shared genome analysis of Staphylococcus aureus isolates from a New Zealand primary school(Springer Nature Limited, 2021-10-13) Scott P; Zhang J; Anderson T; Priest PC; Chambers S; Smith H; Murdoch DR; French N; Biggs PJEpidemiological studies of communicable diseases increasingly use large whole-genome sequencing (WGS) datasets to explore the transmission of pathogens. It is important to obtain an initial overview of datasets and identify closely related isolates, but this can be challenging with large numbers of isolates and imperfect sequencing. We used an ad hoc whole-genome multi locus sequence typing method to summarise data from a longitudinal study of Staphylococcus aureus in a primary school in New Zealand. Each pair of isolates was compared and the number of genes where alleles differed between isolates was tallied to produce a matrix of "allelic differences". We plotted histograms of the number of allelic differences between isolates for: all isolate pairs; pairs of isolates from different individuals; and pairs of isolates from the same individual. 340 sequenced isolates were included, and the ad hoc shared genome contained 445 genes. There were between 0 and 420 allelic differences between isolate pairs and the majority of pairs had more than 260 allelic differences. We found many genetically closely related S. aureus isolates from single individuals and a smaller number of closely-related isolates from separate individuals. Multiple S. aureus isolates from the same individual were usually very closely related or identical over the ad hoc shared genome. Siblings carried genetically similar, but not identical isolates. An ad hoc shared genome approach to WGS analysis can accommodate imperfect sequencing of the included isolates, and can provide insights into relationships between isolates in epidemiological studies with large WGS datasets containing diverse isolates.Item A first nation-wide assessment of soil-transmitted helminthiasis in Fijian primary schools, and factors associated with the infection, using a lymphatic filariasis transmission assessment survey as surveillance platform(Public Library of Science (PLoS), 2020-09) Kim SH; Stothard JR; Rinamalo M; Rainima-Qaniuci M; Talemaitoga N; Kama M; Rafai E; Jang S; Kim JY; Oh YM; Kim E-M; Hong S-T; Lowry JH; Verweij JJ; Kelly-Hope LA; Choi M-HBackground Soil-transmitted helminthiasis (STH) is endemic in Fiji but its prevalence is not known and likely to have changed after a decade of mass drug administration (MDA) for lymphatic filariasis (LF). By linking with LF transmission assessment surveys (LF-TAS), we undertook the first nation-wide assessment of STH in Fijian primary schools, as well as an analysis of factors associated with STH infections. Methodology/Principal findings A cross-sectional assessment for STH was conducted in all four Divisions of Fiji from 2014 to 2015. In the Western, Central, and Northern Divisions, schools were sub-sampled after LF-TAS, while, in the Eastern Division, schools were selected via simple random sampling. For the diagnosis of STH, stool samples were examined by coproscopy with a single Kato-Katz thick smear (KK) and the formol-ether-acetate concentration technique, except for the samples from the Eastern Division where only KK was used. Mean prevalence of any STH among class 1–2 students at the national level was 10.5% (95% CI: 6.9–15.5). Across the three Divisions via LF-TAS, the prevalence levels for ascariasis were 8.7% (95% CI: 4.3–16.6), hookworm 3.9% (95% CI: 2.3–6.6) and trichuriasis 0%. In the Eastern Division, ascariasis prevalence was 13.3% (95% CI: 6.4–25.6), and hookworm 0.7% (95% CI: 0.2–2.5), with one case of trichuriasis. Among class 3–8 students, ascariasis prevalence was lower. Lower risk of any STH was associated with wearing shoes (adjusted OR 0.54, 95% CI: 0.32–0.90) and having piped water from the Fiji Water Authority at home (adjusted OR 0.48, 95% CI: 0.25–0.92). Conclusions After a decade of community-based LF-MDA, STH in school-age children in Fiji is now close to 10%, but localities of endemicity remain. Preventive chemotherapy should be maintained in areas with elevated STH prevalence alongside targeted delivery of integrated WASH interventions. LF-TAS has provided an opportunity to develop future public health surveillance platforms. Author summary Soil-transmitted helminth infections (STH) are common in school-age children in the developing world and can cause morbidity to affected human beings depending on the intensity and duration of infection. In Fiji, where there has been a long history of implementing a program for eliminating lymphatic filariasis (LF) due to inadequate sanitation conditions, there is a need to assess the current epidemiological profile of STH since the LF mass drug administration (MDA) as a community-based intervention may soon stop. By linking with ongoing LF-transmission assessment surveys (LF-TAS), we undertook the first nation-wide assessment of STH in Fijian primary schools. Mean prevalence of STH across three Divisions of Fiji in class 1–2 students chosen for LF-TAS was 12.1% (ascariasis 8.7%, hookworm 3.9%, and trichuriasis 0%). In the remaining Division, the Eastern, ascariasis prevalence was 13.3%, and hookworm 0.7%. Wearing shoes and use of piped water reduced the prevalence of STH. It is concluded that STH in school-age children in Fiji is at low levels, but hot spot localities of elevated STH endemicity remain. Therefore, preventive chemotherapy should be maintained in these localities alongside targeted delivery of appropriate integrated water, sanitation and hygiene interventions.Item Lack of awareness of nursing as a career choice for men: A qualitative descriptive study(John Wiley & Sons Ltd, 2022-12) Guy M; Hughes K-A; Ferris-Day PAims: This research aimed to identify the factors that impact why men do not view nursing as a career choice. Design: Qualitative description was utilized to capture the rich narratives and insight of participants. Methods: Through convenience sampling, nine New Zealand qualified male nurses within their first three years of practice were recruited. Semi-structured interviews were conducted between November 2019 and January 2020 via zoom from sites across New Zealand. All interviews were recorded and transcribed, with the data analysed using Braun and Clarke's thematic analysis. Results: The findings reflected the experiences of the research participants as they made sense of a predominantly female-dominated work environment both during their undergraduate training and prior to recruitment. The research identified two key themes: The first found that men in nursing experienced isolation due to the societal gendering of nursing influencing the participant's knowledge and understanding of what nursing was, as a career. The second theme found that for participants, nursing was not prominent in their awareness when leaving school and making career choices. Conclusion: This research indicates that nursing as a career choice for men is still underpinned by a lack of understanding of the actual role of the nurse and what nurses do, and is more supported by a societal perception that nursing is still a feminized profession. Findings can be used to make recommendations for change in the profession to strengthen diversity in the workforce and redefine the recruitment of men into nursing. Impact: This research reviewed the career choices of men in nursing and why they chose nursing as a profession. Understanding the barriers of why men do not consider nursing as a career choice assists with finding strategies in both the clinical and academic environments that can enable greater gender diversity within the nursing profession. No patient or public contribution: This applies to this research as the focus was on male registered nurses only.Item Motivations for Caffeine Consumption in New Zealand Tertiary Students(MDPI (Basel, Switzerland), 2021-11-25) Stachyshyn S; Wham C; Ali A; Knightbridge-Eager T; Rutherfurd-Markwick KCaffeine-related health incidents in New Zealand have escalated over the last two decades. In order to reduce the risk of substance-related harm, it is important to understand the consumers' motivations for its use. This is especially true for tertiary students who are presumed to be at a higher risk due to seeking out caffeine's well-known cognitive benefits as well as the targeted marketing of such products to young adults. This study examined the habits and motivations for caffeine consumption in tertiary students in New Zealand. A previously validated caffeine consumption-habits (CaffCo) questionnaire was administered online to 317 tertiary students (n = 169 females), aged ≥16 years. Of the 99.1% of participants who regularly consumed caffeine, coffee (76.3%) tea (71.6%) and chocolate (81.7%) consumption were the most prevalent. Motivations for caffeinated-product consumption differed according to caffeine source. Tea was consumed for the warmth and taste, coffee was consumed to stay awake and for warmth, and chocolate, for the taste and as a treat. Marketing was not identified by participants as influencing their consumption of caffeinated products. Knowledge of motivations for caffeine consumption may assist in identifying strategies to reduce caffeine intake in those New Zealand tertiary students who regularly consume amounts of caffeine that exceed safe level.Item Caffeine Consumption Habits of New Zealand Tertiary Students(MDPI (Basel, Switzerland), 2021-04-28) Stachyshyn S; Ali A; Wham C; Knightbridge-Eager T; Rutherfurd-Markwick KAdverse effects associated with excessive caffeine consumption combined with increasing numbers and availability of caffeine-containing products are causes for concern. Tertiary students may be at increased risk of consuming excessive amounts of caffeine due to seeking caffeinated products with well-known wakefulness effects and cognitive benefits. This study explored caffeine consumption habits of New Zealand tertiary students (317; ≥16-years) using a previously validated caffeine consumption habits (CaffCo) questionnaire. Most (99.1%) regularly consumed caffeinated products, especially chocolate, coffee and tea, with coffee, tea and energy drinks contributing most to total caffeine intake. Median estimated caffeine intake was 146.73 mg·day-1, or 2.25 mg·kgbw-1·day-1. Maximum and minimum intakes were 1988.14 mg·day-1 (23.51 mg·kgbw-1·day-1) and 0.07 mg·day-1 (0.02 mg·kgbw-1·day-1), respectively. One-third (34.4%) of caffeine consumers ingested caffeine above the adverse effect level (3 mg·kgbw-1·day-1) and 14.3% above the safe limit (400 mg·day-1). Most caffeine consumers (84.7%), reported experiencing at least one 'adverse symptom' post-caffeine consumption, of which 25.7% reported effects leading to distress or negatively impacting their life. Experiencing 'adverse symptoms' did not, however, curtail consumption in the majority of symptomatic participants (~77%). Public health initiatives directed at tertiary students may be important to reduce potential caffeine-related harm.
