Children aged between 12 and 15 are most likely to take up smoking
The health of young people in Jersey has improved over the past decade, the medical officer of health has said.
A health survey has shown that there has been a downward trend in unhealthy behaviour among teenagers, such as inactivity, smoking and drinking.
Dr Rosemary Geller said when the questionnaire was first given to Jersey pupils more than a decade ago they were more unhealthy than their UK peers.
But she said that trend had now reversed thanks to new health projects.
A lot of work has been done in schools that has helped discourage unhealthy behaviour, said Dr Geller.
And broader health initiatives, such as increasing the price of cigarettes, had also helped, she said.
But Dr Geller told BBC Jersey more still needed to be done to prevent young people from smoking.
The survey showed the ages between 12 and 15 years old were the most likely for children in Jersey to take up smoking.
