Table 9 Estimates and standard errors of covariates in the best fitting mixed models fitted to height

From: Body mass index and height over three generations: evidence from the Lifeways cross-generational cohort study

Effect Estimate Standard error p-value   Correlation 95% CI p-value
Model a) Fitted to maternal line only ‡
Education 0&1 vs 2 -0.71 0.363 0.0508 Child and Mother 0.352 (0.271,0.427) <0.0001
Effect of age within children     Child and MGM 0.164 (0.007, 0.312) 0.0403
Age*child 5.25 0.631 <0.0001 Child and MGF 0.25 (0.051, 0.428) 0.0137
No effect of age in other groups.     Mother and MGF 0.431 (0.243, 0.584) <0.0001
Model (b) Paternal line only ‡
Effect of age within group.
age*Child 5.28 0.634 <0.0001 Child and father 0.509 (0.141, 0.744) 0.0071
age*PGM -0.12 0.075 0.0957 Child and PGM 0.283 (0.078, 0.463) 0.0069
age*PGF -0.19 0.099 0.0586 Child and PGF 0.264 (0.007, 0.486) 0.0427
No effect of age in other groups.     PGM and PGF 0.376 (0.049, 0.624) 0.0231
  1. Also shown are the significant (p < 0.05) correlation estimates between family members.
  2. MGM: Maternal grandmother, MGF: Maternal grandfather, PGM: Paternal grandmother, PGF: Paternal grandfather
  3. Model with vs without correlation terms p < 0.0001
  4. Note: Sample size too small to establish a correlation between father and PGF or PGM
