Data were taken from a large population based study of 9,875 Norwegian adolescents aged 16 19.
Therefore, to our knowledge, there has been only one community-based study of adolescents, which found an association between low dietary fiber intake and overweight but did not link constipation to overweight [ 13].
OBJECTIVE: The purpose of the present paper is to provide an integrated overview of the research methodology and key findings from a decade of research on family meals as part of Project EAT (Eating Among Teens), a large, population-based study of adolescents.
On the other hand, in a cross-sectional MRI-based study of adolescents and young adults, Samarzis et al. [ 49] reported that juvenile disc degeneration was strongly associated with being overweight.
These results are consistent with previous cross-sectional studies, including a community-based study of adolescents exposed to PFOA-contaminated water, and cross-sectional study of adult NHANES participants [ 9– 13, 13].
25 A recent population-based study of adolescents has suggested a dose response relationship between frequency of childhood physical abuse and severe headaches, including migraine, 23 supported by findings from a large convenience sample study of adults, 26 and a multicentre study of adult migraineurs, alike.
Most large population based studies among adolescents are conducted at mainstream schools, thus targeting only the majority group of adolescents [ 6, 11, 15].
The school based study population excludes high-risk adolescents or adolescents with severe symptoms not attending school.
