Mental disorders contribute substantial burden to the society due to their widespread occurrence and debilitating effects. A quarter of the world’s population are children and adolescents, a significant number of whom experience mental disorders as early as the age of 14. Some interventions have been found to effectively reduce the risk factors and reinforce protective or preventive factors. However, there is still a need to put emphasis on mental health promotion strategies such as religious education. This paper aims to discuss the importance of religious education in promoting mental health. Religious education can be instrumental to improving adolescent mental health. Specifically, it can: (1) help develop healthier reaction to stimuli through the internalization of religious morality; (2) reinforce religious coping mechanisms which reduce the impact of stresses, enhance coping skills, and promote a less risky lifestyle; (3) increase awareness regarding religious beliefs and practices and their influence on the individual, the family, and the community; and finally, (4) promote connectedness which can enhance self-esteem and well-being. However, negative health outcomes such as discrimination and social isolation can also develop, especially among religious or gender minority groups. It is important to reflect on the crucial role of religious education on adolescent mental health. School-based mental health education and promotion strategies can maximize the benefits of religious education by putting emphasis on effective implementation of religious education to positively influence adolescent mental health.

Globally, suicide is a significant cause of death among adolescents. Previous studies conducted in high-income countries suggest that students in alternative schools are more likely to engage in suicidal behaviors than those in formal schools. This study aimed to document suicidal ideation and behaviors among adolescent learners enrolled in the Alternative Learning System (ALS) in Manila, Philippines. A mixed methods study was conducted in 24 ALS centers in the city of Manila. ALS centers were stratified according to congressional district and selected using probability proportionate sampling. A cross-sectional survey to determine attitudes towards suicide and prevalence of suicidal ideation and behaviors was administered to 171 learners aged 13 to 17 years old. In-depth interviews with 18 teachers and 12 learners were conducted to explore the school psychosocial environment’s role on learners’ suicidal ideation and behaviors. Exploratory factor analysis was used to extract attitude factors. Fisher’s exact test and Student’s t-test were used to identify differences in sociodemographic characteristics and attitudes towards suicide between learners with or without suicidal ideation or behaviors. Qualitative data were analyzed using thematic analysis. Non-specific active thoughts were the most common type of lifetime suicidal ideation (40.9%) while passive ideation was the most common in the past month (13.5%). Aborted suicide attempt was the most frequent behavior in both lifetime (16.4%) and in the past month (4.7%). Non-fatal suicide attempt in the past month was 2.3%, reaching 12.9% for the entire lifetime. Age, sex, education, and attitudes towards suicide were significantly associated with suicidal ideation or behavior. Thematic analysis showed five themes: (1) fostering belongingness, (2) securing learners’ safety, (3) teaching philosophy, (4) teacher and learner beliefs towards suicidal behavior, and (5) availability of school-offered and community-based services. Suicidal ideation and behaviors are prevalent among adolescent ALS learners. This study also showed a significant difference in attitudes towards suicide and sociodemographic characteristics between learners with and without suicidal ideation behaviors. It also suggests that the school psychosocial environment, through social norms and learner-teacher interactions, can potentially prevent progression of suicidal ideation to behavior, influence help-seeking, and promote mental health among learners.

School health promotion in South‐East Asia has developed rapidly in recent years, and Japan has been one of the significant contributors to the reinforcement of school health promotion in the region. Starting from the Hashimoto Initiative on global parasite control, Japan advocated for international partnerships with several agencies for the development of school health programs in South‐East Asia. Through a strengthened collaboration with international organizations, countries such as the Lao PDR, Cambodia, the Philippines, and Thailand have created and implemented school health programs on nutrition, sanitation, and deworming, among others. In addition to school health program formulation and implementation, the expanded network in South‐East Asia led to more capable school health personnel, with many workers in the education and health sectors benefitting from the training programs jointly held by collaborating organizations.

Background and purpose: Mental health has emerged as an important public health concern in recent years. With a high proportion of children and adolescents affected by mental disorders, it is important to ensure that they are provided with proper care and treatment. With the goal of sharing the activities and good practices on child and adolescent mental health promotion, care, and treatment in Japan and the Philippines, the National Center for Global Health and Medicine conducted a training program on the promotion of mental health focused on treatment and care in Japan and the Philippines in September and November 2019. Key highlights: The training program comprised of a series of lectures, site visits, and round table discussions in Japan and the Philippines. The lectures and site visits focused on the current situation of child and adolescent psychiatry, diagnosis of childhood mental disorders, abuse, health financing for mental disorders, pharmacotherapy, psychotherapy, and disaster child psychiatry in both countries. Round table discussions provided an opportunity to explore the similarities and differences between the two countries in terms of the themes discussed during the lectures. The training program identified the need to collaborate with other professionals to improve the diagnosis of mental disorders in children and adolescents and to increase the workforce capable of addressing mental health issues among children and adolescents. It also emphasized the importance of cooperation between government efforts during and after disasters to ensure that affected children and their families are provided with the care and support that they need.

Natural disasters such as earthquakes, typhoons, floods, and volcanic eruptions frequently occur in Republic of Philippines and mental health care for children affected by these natural disasters is a major public health concern. Aiming to train health professionals on children’s mental health, to conduct a situational analysis to identify the local needs and resources for children’s mental health, and to propose a mental health program for children that can be transferred from Japan to the Philippines, the National Center for Global Health and Medicine (NCGM) conducted a training program for children’s mental health in disaster-affected areas in Japan and the Philippines in June, October, and December, 2017. The training was organized by NCGM for the Program for International Promotion of Japan’s Healthcare Technologies and Services funded by Ministry of Health, Labour, & Welfare, Japan in relation to the Memorandum of Understanding in the Field of Healthcare between NCGM in Japan and University of the Philippines Manila, College of Public Health. The training program consisted of classroom trainings, site visits, and round table discussions in Japan and the Philippines. The classroom trainings and site visits focused on two points: the experiences of individuals and families who survived the Great East Japan Earthquake (GEJE) in 2011 and super typhoon Haiyan in 2013 and the program and activities, especially on mental health, of various government and non-government organizations in helping the affected families and communities. The round table discussion, on the other hand, was conducted to identify challenges related to children’s mental health in disaster-affected areas and to develop recommendations to address these challenges. The major recommendations for the Philippines were to give equal emphasis to physical and psychosocial preparedness and to develop a comprehensive program to care for carers. In Japan, public health and mental health should be integrated in the Disaster Medical Service. Experts from both countries should also generate evidence on the effectiveness of interventions in reducing mental health stigma and collaborate with school personnel and communities in order to learn more about psychosocial preparedness. Finally, mental health must be mainstreamed in programs not only in Japan but also in other countries. The training program enabled key stakeholders to describe the current situation of mental health in Japan and the Philippines, to identify mental health challenges common to disaster-affected areas in both countries, and to propose short- and long-term plans and recommendations. The training program is expected to address the mental health needs of children in disaster-affected areas through a responsive community-based support network. The training participants agreed to form a network and build partnerships toward the common goal of mainstreaming community-based support for children’s mental health in disaster-affected areas in Japan and the Philippines.

Background: The WHO's Health Promoting Schools (HPS) framework is based on an understanding of the reciprocal relationship between health and education, and the need to take a holistic approach to health promotion in schools. We aim to clarify the degree to which the HPS framework is reflected in the national policies of eight target countries and the issues surrounding its successful implementation. Methods: Date were collected through two expert workshops with participants from eight Asian countries: Cambodia, China, Japan, Korea, Lao PDR, Nepal, the Philippines, and Thailand. In the first workshop, data collected on national policy were mapped against the HPS framework. From this, key issues were identified, and follow‐up data collection was conducted in each country for a second workshop. Results: We identified a policy shift toward the HPS framework in six out of the eight countries. Neither Japan nor Korea had changed their national policy frameworks to reflect an HPS approach; however, in the latter, model programs had been introduced at a local level. We identified various barriers to successful implementation, especially in relation to mental health and wellbeing. Conclusion: Given the recent shift toward the HPS approach in six out of the eight countries in this study, there is a need to conduct research to assess the impact of this framework on the health and wellbeing of students and school staff. At the same time, we call for more dialog in the context of Japan to explore the possible benefits of introducing the HPS framework into schools.
