Temporal trends in food group availability and cancer incidence in Africa: an ecological analysis

Objective: We evaluated the relationship between food availability, as the only dietary exposure data available across Africa, and age-standardised cancer incidence rates (ASR) in eighteen countries. Design: Ecological study. Setting: Availability of food groups and dietary energy was considered for five hypothetical time points: years of collection of ASR ( T 0 ) and 5, 10, 15 and 20 preceding years ( T –5 , T –10 , T –15 , T –20 ).
