Healthy Lifestyle DQX

Overview

The healthy lifestyle score ranges from 0 to 7 points. A higher score reflects greater adherence to the 2018 WCRF/AICR Cancer Prevention recommendations.

The DQX healthy lifestyle score (hl_score_dqx) is the sum of 7 components. The table below describes how points are assigned for each component and provides the variable names of the components. The source of the data (i.e., the questionnaire) is also listed:

Note: PLCO does not have waist circumference data so the “healthy weight” component only accounts for BMI. Also note that PLCO does not have breastfeeding data, so the optional eight component is not included in the DQX healthy lifestyle score.
