Food patterns and body weight in young adulthood and associations with food consumption throughout childhood: findings from a birth-cohort study
Bibliographic record
Abstract
This study aimed to investigate (1) the longitudinal associations between food patterns and body weight in young adulthood and (2) how food patterns of young adults relate to food consumption in early, middle and late childhood. The study sample includes 700 participants of the Québec Longitudinal Study of Child Development. During childhood, frequency of consumption of various foods was reported on ten occasions between 1·5 and 13 years. At age 22 years, food frequency questions (with quantities) were used to derive four food patterns (labelled healthy, beverage rich, protein rich and high energy density) through exploratory factor analysis. Self-reported height and weight were collected at 22 and 23 years. Regression analyses were performed to assess the associations between (1) food patterns and weight outcomes a year later (BMI, BMI change and overweight status) and (2) frequency of consumption of eight food groups in childhood and food patterns in adulthood. Dietary habits characterised by the consumption of vegetables, fruit, plant-based sources of protein and whole-grain cereal products were related to a lower risk of obesity a year later. Conversely, dietary habits characterised by a high consumption of energy-dense foods, of animal sources of proteins and, among women, of high quantities of liquids were associated with higher risk of excess weight a year later. Healthier food choices in childhood were associated with healthier food patterns in young adulthood. These findings reinforce the value of preventive dietary interventions in the early years to foster eating environments that favour healthy eating and healthy weights in adulthood.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
