Relative Association Between the Presence of Individual Conditions on Time to Developing Incident Multimorbidity Between 2002-2003 and 2012-2013: Complementary Log-Log Model
| Condition | HR (95% CI) | P Value |
|---|---|---|
| Hypertension | 1.00 [Reference] | … |
| Ischemic heart disease | 1.27 (0.91-1.78) | .162 |
| Arrhythmia | 1.55 (1.06-2.26)a | .024a |
| Diabetes mellitus | 1.06 (0.63-1.78) | .839 |
| COPD | 2.32 (1.55-3.46)a | <.001a |
| Asthma | 1.33 (1.05-1.70)a | <.019a |
| Arthritis (any) | 0.98 (0.83-1.16) | .819 |
| Osteoporosis | 1.32 (0.87-2.01) | .185 |
| Cancer (any) | 1.19 (0.86-1.63) | .295 |
| Affective mental health condition (any) | 0.97 (0.71-1.31) | .831 |
| Otherb | 1.21 (0.64-2.30) | .552 |
COPD = chronic obstructive pulmonary disease; HR = hazard ratio.
Note: From a sample of participants having 1 condition in 2002-2003 (n = 1,534), and an outcome of 1 or more incident conditions. Complementary log-log models are discrete time equivalent of Cox proportional hazards models for continuous time. This model adjusted for all baseline patient characteristics, and differential nonresponse using longitudinal sample weighting. HR >1.00 represents increased risk; an HR of <1.00 indicates reduced risk.
Conditions significantly more more likely than hypertension to be associated with incident multimorbidity.
Includes participants with conditions with low prevalence; congestive heart failure, stroke, psychotic mental health condition, and dementia/Alzheimer’s (Table 2). Combined, these individuals in the “other” category accounted for <1% of the sample.
