**6. Conclusion**

Research evidence reveals a complex relationship between health and academic achievement. Studies that have been carried out show a significant correlation between academic performance and health problems such as mental illness, depression and anxiety, vision and oral health problems, asthma, teen pregnancy, malnutrition, obesity, chronic stress, aggression and violence, unsafe sexual activity, unhealthy eating, physical inactivity and substance abuse. The effects of such health problems include poor retention, school failure, grade retention, school dropout, absenteeism and poor concentration. Research has also revealed that the more health risks students had, the more likely it was that they also were at academic risk. Schools and universities are in a unique position of educating students about life in general and more specifically about diseases. Schools should create enabling environments and policies that and support services promote student health individually and collectively. Comprehensive school health services, which comprise multiple interventions, are said to positively contribute to the academic performance of students.
