The association between the duration and degree of adiposity and appetitive trait trajectory profiles from childhood into early adolescence – results from the Generation XXI cohort
Authors' conclusion
Children with the highest cumulative adiposity between 4 and 13 y were more likely to present an 'avid appetite' during childhood. Additionally, having excessive weight at age 7 may indicate a higher appetite in subsequent years.
Study context
- Population
- Children of the Generation XXI birth cohort (Porto, Portugal) with weight and height measured at 4, 7, 10 and 13 y; appetitive traits by Children's Eating Behaviour Questionnaire at 7, 10 and 13 yfinal sample
- Participants
- 3,339 children
- Exposure
- Cumulative adiposity and appetitive trait trajectory profiles
- Outcome
- Association of body mass index (BMI) area under the curve (BMIAUC, accumulated adiposity) with appetitive trait trajectory profiles
- Follow-up
- BMI 4–13 y; appetite 7–13 y
Methodological detailspopulation-based birth cohort, multinomial logistic regression
