Adjusted prevalence ratios* of nonadherence for chronic conditions and consequences of cost-related nonadherence in relation to household food insecurity status
| Household food insecurity status | Characteristic/consequence; prevalence ratio (95% CI) | ||
|---|---|---|---|
| Nonadherence for chronic conditions n = 902† | Worse health n = 890† | Greater use of health care services n = 909† | |
| Food secure | 1.00 (ref) | 1.00 (ref) | 1.00 (ref) |
| Marginally food insecure | 1.03 (0.75 to 1.40) | 1.31 (0.88 to 1.96) | 1.65 (0.77 to 3.54) |
| Moderately food insecure | 1.28 (1.07 to 1.53) | 1.48 (1.11 to 1.98) | 1.66 (0.97 to 2.85) |
| Severely food insecure | 1.42 (1.11 to 1.79) | 1.63 (1.18 to 2.24) | 2.86 (1.72 to 4.74) |

↵* From Poisson regression with bootstrapped standard error.
All models were adjusted for household income, imputed income, income source, sex, age, Aboriginal status, housing tenure, household type, province, drug insurance status and number of different drugs prescribed.
↵† Unweighted number of observations.
Variation is due to the varying number of respondents with missing answers to each of the 3 questions from the Canadian Community Health Survey Rapid Response questionnaire on prescription drug use (PCN_Q030, PCN_035 and PCN_040) (see Appendix 1).
