Notes:
1. Based on original sample members with responses in all three waves who are aged over 15 at the end of the reference period in Wave 1. Full-time students and those 65 years of age and over are excluded. Data for all three waves is pooled together to create an average rate. The sample is restricted so it is the same as that considered in the models with individual chronic diseases (ie, those with missing indicators of chronic diseases are excluded from this analysis).
2. The means and standard deviations for the non-health variables are the same as those from the individual disease models (Table D2).

Notes:
1. Based on original sample members with responses in all three waves who are aged over 15 at the end of the reference period in Wave 1. Full-time students and those 65 years of age and over are excluded. Responses in each wave are included in the model separately. The relationship between person responses in each wave was accounted for by defining the people as clusters. The number of observations in each wave is not equal owing to the small number of missing values for variables of interest in certain waves or owing to student/retirement status changing between waves. All variables were included in the model and significant and insignificant variables or variable categories are kept in for completeness.
2. *Significant at the 90% level. **Significant at the 95% level. ***Significant at the 99% level.
3. The sample is restricted so it is the same as that considered in the models with individual chronic diseases (ie, those with missing indicators of chronic diseases are excluded from this analysis).
4. The likelihood of labour market participation was modelled. Not participating is the base category.
