diet_score_fun_cat | R Documentation |
This function creates a categorical derived diet variable (diet_score_cat3) that categorizes derived diet score (diet_score).
diet_score_fun_cat(diet_score)
diet_score |
derived variable that calculates diet score.
See |
The diet score is based on consumption of fruit, salad, potatoes, carrots, other vegetables and juice. 2 baseline points plus summation of total points for diet attributes. Negative overall scores are recoded to 0, resulting in a range from 0 to 10.The categories were based on the Mortality Population Risk Tool (Douglas Manuel et al. 2016).
diet_score_cat3 uses the derived variable diet_score. diet_score uses sex, and fruit and vegetable variables that have been transformed by cchsflow (see documentation on diet_score). In order to categorize diet across CCHS cycles, sex, and fruit and vegetable variables must be transformed and harmonized.
