Social differences in sexual behaviour and cervical cancer

Area of Science:

• Oncology
• Epidemiology
• Public Health

Background:

• Cervical cancer disproportionately affects women of lower socioeconomic status globally.
• Risk factors include multiple sexual partners, early sexual activity, and reduced screening access.
• Socioeconomic gradients in cervical cancer incidence persist across various regions.

Purpose of the Study:

• To investigate the causes of socioeconomic differences in invasive cervical cancer.
• To examine the role of human papillomavirus (HPV) and sexual behavior in these disparities.
• To analyze data from case-control studies in Colombia and Spain.

Main Methods:

• Conducted two case-control studies in Colombia and Spain.
• Collected data on socioeconomic status, sexual behavior, HPV prevalence, and other risk factors.
• Utilized statistical analysis to adjust for confounding variables.

Main Results:

• HPV and other sexually transmitted diseases were more prevalent in lower socioeconomic strata.
• Husbands of women in lower socioeconomic strata reported more sexual partners and prostitute contact.
• Higher risk of cervical cancer in women with no schooling was significantly reduced after adjusting for HPV and sexual behavior.
• Socioeconomic differences in cervical cancer incidence are partly explained by HPV DNA prevalence.

Conclusions:

• Socioeconomic disparities in cervical cancer are significantly influenced by HPV prevalence.
• Men's sexual behavior, particularly contact with prostitutes, may contribute to higher HPV prevalence in lower socioeconomic groups.
• Targeted interventions addressing sexual health and HPV transmission are crucial for reducing cervical cancer inequalities.
