Fewer Portsmouth teens are smoking and drinking than previous years with a greater number exercising more.
These are the findings from the 2016 'You Say' survey which is run annually by Portsmouth City Council with Year 8 and Year 10 pupils.
42% of students who responded had drunk a whole alcoholic drink, down from 51% in 2015 and a high of 66% in 2011. There is also an increase in the number of pupils who had never tried alcohol.
94% of Year 8 pupils and 79% of Year 10 pupils had never tried tobacco, up from 91% and 72% respectively in 2015. There was also a decline in the numbers who smoke daily - now the lowest since 2011.
The number of pupils who reported doing exercise for 30 minutes or more, on five or more days a week, is higher than the previous two years and those who are concerned about their weight is lower than the previous two years.
Drinking energy drinks is also down, with 33% of Year 10 students and 39% of Year 8 students having drunk at least one in the 4 weeks before the survey, versus 49% and 47% in 2015.
Cllr Luke Stubbs, Cabinet Member for Public Health and Adult Social Care, said; "It's really positive to see that young people in Portsmouth are choosing to follow a healthier lifestyle. We know that the habits people form when they're young often stay with them as they get older so by choosing not to smoke or drink now, and by adopting good levels of physical activity, the next generation is on course to be in better health."
