HIGH SCHOOL SHOULD START AT 10 TO 11


A study by researchers from the University of Oxford, Harvard Medical School and the University of Nevada has found that current school and university start times are damaging the learning and health of students
Drawing on the latest sleep research, the authors conclude students start times should be 08:30 or later at age 10; 10:00 or later at 16; and 11:00 or later at 18. Implementing these start times should protect students from short sleep duration and chronic sleep deprivation, which are linked to poor learning and health problems.
These findings arise from a deeper understanding of circadian rhythms, better known as the body clock, and the genes associated with regulating this daily cycle every 24 hours.
It is during adolescence when the disparity between inherent circadian rhythms and the typical working day come about. Circadian rhythms determine our optimum hours of work and concentration, and in adolescence these shift almost 3 hours later. These genetic changes in sleeping patterns were used to determine start times that are designed to optimize learning and health.
The US Department of Health has also recently published an article in favor of changing the start times for Middle and High Schools.
Corresponding author Paul Kelley (Honorary Clinical Research Associate, Sleep and Circadian Neuroscience Institute, University of Oxford) will be presenting Time: the key to really understanding our lives at the British Science Festival on Tuesday 8 September.

INVESTING IN SEXUAL REPRODUCTIVE HEALTH OF 10 TO 14 YEAR OLDS YIELDS TIME BENEFITS


Age 10 to 14 years, a time when both girls and boys are constructing their own identities and are typically open to new ideas and influences, provides a unique narrow window of opportunity for parents, teachers, healthcare providers and others to facilitate transition into healthy teenage and adulthood years according to researchers from Georgetown University's Institute for Reproductive Health who note the lack worldwide of programs to help children of this age navigate passage from childhood to adulthood.

An estimated 1.2 billion adolescents live in the world today -- the largest number of adolescents in history. Half are between the ages of 10 and 14 -- years of critical transition from child to teenager. These are the years in which puberty is experienced, bringing with it physical and other changes that may be difficult for a youngster to understand, yet set the stage for future sexual and reproductive health.
Nevertheless, the opportunity to reach very young adolescents during the very years when sexual and reproductive health behaviors lasting a lifetime are being developed is frequently missed, the Institute for Reproductive Health researchers note. They report that educators, program designers, policy-makers or others typically do not view 10 to 14 year olds as a priority because the long-term benefits and value of investing in them goes unrecognized.
In "Investing in Very Young Adolescents' Sexual and Reproductive Health" published online in the peer-reviewed journal Global Public Health, in advance of print publication in issue 9:5-6, the Institute for Reproductive Health researchers advocate the investment of resources to lay foundations for future healthy relationships and positive sexual and reproductive health, identifying specific approaches to reach these very young adolescents. They say that programs to engage 10 to 14 year olds must be tailored to meet their unique developmental needs and take into account the important roles of parents and guardians and others who influence very young adolescents.
"Ten is not too young to help girls and boys understand their bodies and the changes that are occurring. Ten is not too young to begin to move them from ignorance to knowledge," said Rebecka Lundgren, MPH, senior author of the paper. "We need to reach 10 to 14 year olds, often through their parents or schools, to teach them about their bodies and support development of a healthy body image and a strong sense of self worth. We also need to hear their voices -- the voices of the under-heard and underserved. Ten is not too young." Lundgren is the director of research at the Institute for Reproductive Health.
The paper notes that preventive reproductive and sexual health services designed to suit the needs of very young adolescents are virtually non-existent in lower- and middle-income countries and that worldwide, family life education, youth centers, and youth-friendly health services with programs specifically targeted to 10 to 14 year olds rarely exist.
According to the World Health Organization and other groups, misinformation abounds about fertility (including first menstruation and ejaculation), sex, sexuality and gender identity in this age group. Very young adolescents often rely on equally uninformed peers or older siblings and the media for information.
According to Lundgren, the few existing programs for youths age 10 to 14 years typically focus on girls. "We need to expand that focus to include boys, laying a foundation for both girls and boys to learn and communicate with peers, parents, teachers and health providers as they develop positive self images and healthy practices in order to move this age group from vulnerability to empowerment."
