We analyzed the trends for two important cancers affecting females, breast cancer and cervical cancer, using the Indian cancer registry data and correlated the findings with selected relevant sociodemographic and behavioral indicators.
We examined National Family Health Survey data for the respective states in which registries are located, on relevant indicators like multiparity, early childbearing, cervical examination, multiple sexual partners/high-risk sexual behavior, and HIV prevalence (for cervical cancer), multiparity, early childbearing, duration of breastfeeding, overweight, alcohol use, and clinical breast examination (for breast cancer). We used Global Adult Tobacco Survey smoking data.
The top four positions in cancer cervix were all in registries from northeast India with a higher proportion of multiparous women (≥3 births; around 40%), whereas three major metros in the south and the national capital of Delhi, all with a relatively low proportion of multiparous women (11-25%) topped the chart for breast cancer. Overweight/obesity was higher in states with a higher incidence of breast cancer (23.3-31%) compared to states with a lower incidence (12.2-16%). No clear patterns emerged with regard to alcohol consumption, duration of breastfeeding or clinical breast examination.
The shift in the childbearing age group explains the increasing breast cancer rates in urban areas, whereas the persisting higher rate of multiparity explains higher cervical cancer rates especially in underserved states in the northeast. India needs to invest in transforming its cancer control program to be a more resilient one with a focus on screening and prevention.
我们利用印度癌症登记数据,分析了影响女性的两种重要癌症——乳腺癌和宫颈癌的发病趋势,并将研究结果与选定的相关社会人口统计学和行为指标进行关联。
我们研究了各癌症登记处所在邦的全国家庭健康调查数据,涉及多胎生育、早育、宫颈检查、多个性伴侣/高危性行为以及艾滋病毒感染率(针对宫颈癌)、多胎生育、早育、母乳喂养时长、超重、饮酒情况以及临床乳腺检查(针对乳腺癌)等相关指标。我们使用了全球成人烟草调查的吸烟数据。
宫颈癌发病率排名前四位的均来自印度东北部的癌症登记处,多胎生育女性比例较高(≥3次分娩;约40%),而南部的三个主要大城市以及首都德里,多胎生育女性比例相对较低(11 - 25%),在乳腺癌发病率方面位居前列。与发病率较低的邦(12.2 - 16%)相比,乳腺癌发病率较高的邦超重/肥胖率更高(23.3 - 31%)。在饮酒、母乳喂养时长或临床乳腺检查方面未呈现出明显模式。
生育年龄组的变化解释了城市地区乳腺癌发病率上升的原因,而持续较高的多胎生育率则解释了宫颈癌发病率较高的原因,尤其是在东北部医疗服务不足的邦。印度需要投资改革其癌症控制项目,使其更具韧性,重点关注筛查和预防。
