**Diastolic blood pressure was used as a proxy for systolic because of high correlation.
†Temp and haemoglobin were omitted in the adjusted model because of too many missing values.
††P- value for Likelihood Ratio Test in the adjusted model.
aAdjusted for variables included in the final demographic model.
Reference category for logistic regression represented by 1.
Numbers may not add to total sample due to missing values.
