Nova Scotia wants to know more about the eating and exercise habits of children and young people in the province.
A study will track 2,200 Grade 3, 7 and 11 students from 60 schools across the province from early October until next June.
Trends will be calculated using similar studies from 2002 and 2006.
Health Promotion and Protection Minister Maureen MacDonald says the study will help determine if the province is making progress helping young people live healthier lives.
Students involved in the study will wear accelerometers to determine whether they get the recommended 60 minutes of moderate to vigorous physical activity per day, at least five days per week.
Grade 7 and 11 students will also track their eating patterns using an online tool designed to measure how many are eating according to Canada's Food Guide.
