摘要:: Cancer is increasingly responsible for the mortality gap between high and low socioeconomic position groups in high-income countries. This study investigates which cancers are contributing more to socioeconomic gaps in mortality and how this changes over time. New Zealand census data from 1981, 1986, 1991, 1996, 2001, and 2006, were linked to three to five years of subsequent mortality and cancer registrations, resulting in 54 and 42 million years of follow-up cancer incidence and mortality respectively. Age- and ethnicity-standardised cancer mortality rates and the slope index of inequality (SII) by income were calculated. The contribution of cancer to absolute inequalities (SII) in mortality increased from 16% to 27% for men and from 12% to 31% for women from 1981-84 to 2006-11, peaking in 1991-94 for men and in 1996-99 for women and then levelling off, parallel to peaks in lung cancer inequalities. Lung cancer was the largest driver of cancer inequality trends (49% of the cancer mortality gap in 1981-84 to 33% in 2006-11 for men, and 32% to 33% for women) followed by colorectal cancer in men (2% to 11%) and breast cancer in women (declining from 44% to 13%). Women in the lowest income quintile experienced no decline in cancer mortality. The contribution of cancer to income inequalities in all-cause mortality has expanded in this high-income country. Action to address socioeconomic inequalities should prioritise equitable tobacco control, obesity control and improved access to cancer screening, early diagnosis and high quality treatment for those with the lowest incomes.
