Individual-level determinants of breast and cervical cancer screening and early testing in two regionally representative urban Indian populations.

INTRODUCTION

Region-specific data on individual factors associated with uptake of breast and cervical cancer screening or early testing in diverse Indian populations are limited.

AIM

To assess the prevalence and individual determinants of uptake of breast and/or cervical cancer screening or testing among women aged 30-69 years in regionally representative populations of two large Indian cities: New Delhi and Chennai.

METHODS

We conducted an analysis of the cross-sectional data (2016-2017) nested within the Centre for Cardiometabolic Risk Reduction in South Asia cohort, established in 2010-2011 with 12,271 participants (5365 in New Delhi; 6906 in Chennai). Among 3310 women participants, we evaluated the associations of demographic, socioeconomic, lifestyle, medical, psychosocial, and reproductive factors with breast and/or cervical cancer screening or testing using multivariable logistic regression models with results expressed as adjusted odds ratios (OR) and 95% confidence intervals (CI).

RESULTS

At any point prior to 2016-2017, 193 women self-reported having undergone evaluations for breast and/or cervical cancer. The reasons for evaluation were 'general examination' or 'physician's advice' (i.e., screening) or 'being symptomatic' (i.e., early testing). The overall prevalence was 5.8% for screening or testing and 2.5% for screening alone. Formal education (OR:1.88; 95% CI:1.12-3.15), high monthly household income (OR:2.27; 95% CI:1.59-3.25) and less 'fear-of-judgement' (OR:1.65; 95% CI:1.05-2.58) were positively associated with screening or testing uptake. When screening uptake was analysed separately, the results were generally similar.

CONCLUSION

Our findings may have important implications for interventions at community-level (e.g., reducing 'fear-of-judgement', increasing awareness to screening programs and early symptoms) and health-system level (e.g., opportunistic screening).
