In a paper by Walsh et al,1 there was concern expressed that excess body weight (EBW) contributes to many cancers in New Zealand, compounding health inequities with higher proportions of EBW-attributable cancers within Māori and Pacific populations. Pacific peoples had the highest population attributable fraction (PAF) (11.8%), and this was highest among Pacific females (16.1%). Māori also had a higher PAF (6.9%) than European/Other (4.5%).
Early detection and prevention are important. The greatest number of cancers attributable to EBW were colorectal (1,801), followed by uterine (1,331) and breast cancer among postmenopausal females (1,231).
