Table 4 Predictors of change in child’s BMIz from age 5 up to age 9 for children who were overweight at age 5

From: Parental perception of child’s weight status and subsequent BMIz change: the KOALA birth cohort study

  2. Results of multivariate backwards linear regression analyses. Non-significant (P >0.05) predictors were backward-deleted. Variables that were excluded from all models due to non-significance were gender of the child, recruitment channel, country of birth of both parents, employment status of both parents, mother’s BMI and age of mother at the birth of the child.
  3. Analyses were controlled for significant background characteristics: educational level of father, educational level of mother and BMI of father.
