Summary
Written by AI, not yet AICS's view · claude-haiku-4-5-20251001This study analysed dietary patterns among 2,466 Chinese adolescents aged 10-15 using data from 2012. Researchers identified three distinct dietary patterns and measured their association with height. Adolescents following a comprehensive, nutrient-balanced dietary pattern were on average 3.31 cm taller than those following a meat-egg traditional pattern, with consistent findings for height-for-age scores. The results suggest that diverse, nutrient-rich diets are associated with better growth outcomes in adolescents.
Key points
- Three dietary patterns were identified among adolescents: Meat-Egg Traditional, Diverse Protein-Rich, and Comprehensive Nutrient-Balanced
- Adolescents in the Comprehensive Nutrient-Balanced pattern were 3.31 cm taller on average than those in the Meat-Egg Traditional pattern (p < 0.001)
- The Diverse Protein-Rich pattern showed a moderate positive association, with participants approximately 2.00 cm taller than the Meat-Egg Traditional pattern (p = 0.003)
- Height-for-age z-score findings were consistent with absolute height measurements
- Dietary assessment used binary indicators for past-week consumption of eight food groups
Limitations
This is a cross-sectional study, so causality cannot be established; height was parent-reported rather than directly measured, which may introduce recall bias. The study captures a single time point (2012) and cannot determine whether dietary patterns preceded or resulted from height differences.
Abstract
Background Adolescents' growth and development are closely related to dietary patterns, yet evidence on the relationship between overall dietary patterns and adolescent growth in contemporary China is limited. This study aimed to identify major dietary patterns among Chinese adolescents and examine their associations with height and height-for-age z-scores (HAZ). Methods In this cross-sectional analysis of 2,466 adolescents (age 10-15) from the China Family Panel Studies (2012), dietary patterns derived by latent class analysis were examined in relation to parent-reported height. Dietary assessment used eight binary food-group indicators for past-week consumption; height was reported by a parent or guardian. Associations were estimated using multivariable linear regression and reported as adjusted HAZ differences (and corresponding absolute height differences in centimeters). Results Three distinct dietary patterns were identified: Pattern 1 (Meat-Egg Traditional), Pattern 2 (Diverse Protein-Rich), and Pattern 3 (Comprehensive Nutrient-Balanced). In the fully adjusted models, adolescents in Pattern 3 were on average 3.31 cm taller than those in Pattern 1 (p < 0.001). Pattern 2 also showed a moderate positive association, with participants being approximately 2.00 cm taller than those in Pattern 1 (p = 0.003). Findings for HAZ were consistent with those for absolute height. Conclusion These findings suggest that a comprehensive, nutrient-balanced dietary pattern is positively associated with adolescent growth. Promoting nutrient-rich, diversified diets during adolescence could help maximize growth potential and improve developmental outcomes in youth.
