These researchers obtained data from the New Zealand Cancer Registry for this analysis of cervical cancer trends by age and ethnicity between 1985 and 2013, and by morphology between 1997 and 2013. The overall incidence of cervical cancer was 56% lower in 2009–2013 than in 1985–1989, and significant reductions were observed in women aged 25–49, 50–69, and ≥70 years. Substantial, similar reductions in cervical cancer occurred among Māori and non-Māori women aged 25–49 (50% in Māori; 52% in non-Māori) and 50–69 years (65% in Māori; 69% in non-Māori), whereas cervical cancer incidence among women aged 20–24 years has appeared to increase after around 1996. This increasing trend was significant for women aged 20–24 overall and for non-Māori women (p<0.01 in both cases).
