Adjusted odds ratios† and 95% confidence intervals (CI) for the occurrence of new health problems in 2.5 year olds in Quebec longitudinal study of child development (QLSCD 1998–2002) according to the score for lack of money for basic needs
| Acute health problem (n = 1946)OR (95% CI) | Asthma episode (n = 1946)OR (95% CI) | Growth delay‡ (n = 1893)OR (95% CI) | Index of health problems = 2 or 3§ (n = 1893) OR (95% CI) | Hospitalisation (n = 1946)OR (95% CI) | |

| *p<0.05; **p<0.01; ***p<0.00. †All models are adjusted for the previous health of the children at 17 months and the other variables: child’s sex and age, small for gestational age, prematurity and congenital abnormality, type of child care, and mother’s level of education. The model for asthma episode is also adjusted for mother’s age and the presence of a pet in the house. The model for hospitalisation is also adjusted for mother’s age. ‡The threshold for growth delay is established based on the value of 10th centile according to the Z score on the CDC growth curve, 2000. §The index of health problems (IHP) includes presence of 0–1 compared with two to three of the following problems: acute health problems, asthma episode, and growth delay. | |||||
