The increasing suicide morbidity and mortality rates among the adolescent has become a serious human tragedy of great public health concern. Many facets of suicide such as suicide ideation, intent, attempt, ambivalent, gesture, equivalent, and completion are prevalent among this group of people due to their developmental characteristics in an unsupportive cultural and socioeconomic environment, especially in developing countries. Adolescents may at one point or another perceive suicide as a permanent answer to problems, often due to self-doubts, conflict with older ones like parents, fears, confusion, stress, and pressures to succeed or conform while growing up. Due to the fact that suicide is preventable but very difficult to be predicted accurately, it becomes expedient to start to concentrate efforts on identifying, and enhancing suicide protective factors among this age group, and devising and advancing various public health prevention strategies apart from the conventional psychic-medical approaches to stem the tides of suicide among them, especially in developing countries. This study reviews prevalence of suicide among adolescents in developing countries, and proffers public health-based prevention strategies, which, if properly programmed and implemented would be effective in the containment of this public health problem in different settings.

The study was conducted using a correlational research design. A total of 752 teachers in the 20 government-owned senior secondary schools in Delta State's Ika South Local Government Area were included in the study (Source: Post Primary Education Schools Board, Asaba, Delta State, 2021). The study used a sample size of 398 teachers who were chosen at random and independently from 20 government-owned secondary schools in the Ika South Local Government Area of Delta State, Nigeria, using the purposive sampling technique. The purposive sample technique is appropriate for selecting teachers who exhibit the traits that are being examined, namely, Burnout Syndrome. This was accomplished by giving each teacher a copy of the Burnout Syndrome Screening Scale (BSSS). Data was collected using the Emotional intelligence inventory (El) by Akinboye (2005), and Maslach Burnout Scale (MBS). The Cronbach alpha method of internal consistency was used to assess the instruments' dependability. The reliability coefficients were Maslach Burnout Scale (MBS) 0.87, and Emotional Intelligence Inventory (El) 0.79, which are high enough to demonstrate the instrument's reliability. Linear regression and multiple regression were used to evaluate the hypotheses, along with independent sample t-test statistics. The result revealed that emotional intelligence such as self-awareness, self-management, self- motivation, social awareness, and relationship management all predict teacher burnout syndrome in a favorable and substantial way. School boards should recruit more professional counsellors to reduce post-traumatic stress disorder (PTSD) among teachers.
