Summary
Adolescence is a time of major physical, emotional and social change, often characterised by risk taking and experimentation. Behaviours and decisions taken at this time of life will shape future health. This rural cohort study will for the first time will study the influence of pubertal hormones on behaviours, mental and physical health and general well being in adolescents.

Summary
Despite recent major advances in care around the time of birth that have led to large increases in the survival rates for very preterm babies, the rate of adverse long-term health problems has not diminished in survivors, and remains too high compared with children not born very preterm. In particular they have higher rates of substantial problems with the way their brain works, particularly affecting their movement, vision, hearing, thinking and talking. We have just concluded a large clinical ....Despite recent major advances in care around the time of birth that have led to large increases in the survival rates for very preterm babies, the rate of adverse long-term health problems has not diminished in survivors, and remains too high compared with children not born very preterm. In particular they have higher rates of substantial problems with the way their brain works, particularly affecting their movement, vision, hearing, thinking and talking. We have just concluded a large clinical trial in Australia and New Zealand of magnesium sulphate which was given to mothers who were likely to deliver their baby too early (before 30 weeks of pregnancy). We have been able to show, for the first time, that magnesium sulphate was able to halve the rate of substantial problems with movement in 2 year old survivors, from 6% to 3%. However, we are not sure if this potentially important improvement will translate into better outcomes for the children as they grow older and reach school-age. As there are many examples of treatments given around the time of birth that have been shown to have some short-term benefits, but substantial long-term harms, we must be as certain as we can be that any advance in one small area of health is not counterbalanced by disadvantages in other health areas. We plan to assess the 1061 survivors from our earlier clinical trial of magnesium sulphate therapy at ages from 7-8 years, when they are at school. We will assess their movement and other important areas of their brain function, as well as their school progress and general health and growth. If we find important improvements in health at school-age of these children caused by magnesium sulphate therapy, without any substantial counterbalancing side-effects, magnesium sulphate will probably become standard therapy in mothers who are likely to deliver their baby very early. This will lead to a reduction in the burden of illness in the community caused by being born too early.Read moreRead less
SCHOOL-AGE OUTCOME FOR VERY TINY/PRETERM CHILDREN BORN IN VICTORIA IN 1991-92

Summary
The survival rate for tiny or very premature babies has improved dramatically in recent times, from below 10% in the 1960s to greater than 70% in the 1990s. Several new treatments have helped to improve their survival rate, but some have the potential to cause long-term harm to the developing baby's brain or lung, and may cause lifelong problems with thinking, walking, talking, seeing, hearing, growth or breathing. Babies who are very tiny (born weighing less than 1000 g), or born very early (bo ....The survival rate for tiny or very premature babies has improved dramatically in recent times, from below 10% in the 1960s to greater than 70% in the 1990s. Several new treatments have helped to improve their survival rate, but some have the potential to cause long-term harm to the developing baby's brain or lung, and may cause lifelong problems with thinking, walking, talking, seeing, hearing, growth or breathing. Babies who are very tiny (born weighing less than 1000 g), or born very early (born before 28 weeks of pregnancy, or more than 12 weeks premature) will be assessed long term (to 8-9 years of age), as broadly as possible, and in comparison with normal birthweight (NBW, birthweight >2499 g) children. Outcomes will encompass academic progress and behaviour, brain function, general health, growth, and respiratory health. We will compare the outcomes for very tiny-preterm children who were treated with several of these new therapies with those who were not so treated. We will assess whether alternative measures of long term outcome that assess the quality of life are applicable to very tiny-preterm children. If so, these measures could be used much more widely, since they are cheaper and less time-consuming.Read moreRead less
