Explaining socioeconomic inequality in cervical cancer screening uptake in Malawi

High unmet needs for cervical cancer screening among women living with HIV in six African countries: A population-based study

BACKGROUND

Cisgender women living with HIV (WLWH) are disproportionately impacted by cervical cancer. Nevertheless, disparities in uptake and implementation of cervical cancer services persist in sub-Saharan Africa, where population-level estimates of screening coverage remain scarce.

METHODS

We pooled data from nationally representative Population-based HIV Impact Assessment (PHIA) surveys conducted in Ethiopia, Malawi, Rwanda, Tanzania, Zambia, and Zimbabwe (2015-2019). After estimating the prevalence of self-reported lifetime cervical cancer screening (overall and by country), survey-weighted multivariable log-binomial regression identified socio-demographic and clinical correlates of screening uptake among WLWH aged 25-64 years.

RESULTS

Overall, 6933 WLWH (mean age: 39.6 years) were included in the multi-country sample. The pooled prevalence of lifetime cervical cancer screening was 18.5% (range: 8.5% [Rwanda] to 25.3% [Zambia]). Screening uptake varied by HIV clinical status, with serostatus-aware (21.3% vs 9.0%), antiretroviral therapy-experienced (22.0% vs 10.5%), and virally suppressed (22.1% vs 11.6%) WLWH, respectively, reporting significantly (p < 0.001) higher screening rates. Screening was especially low among WLWH aged <35 years (14.7%), with no formal education (12.1%), in the poorest households (7.9%), and residing in rural areas (14.0%).

CONCLUSIONS

Fewer than one-fifth of WLWH had ever screened for cervical cancer, suggesting expanded availability and access to tailored, integrated services are critically needed.

Socioeconomic inequality in cervical cancer screening uptake among women in sub-Saharan Africa: a decomposition analysis of Demographic and Health Survey data

OBJECTIVE

To examine socioeconomic inequalities in the use of cervical cancer screening among women in sub-Saharan Africa.

DESIGN

Secondary data from the Demographic and Health Survey data in sub-Saharan Africa.

SETTING

Sub-Saharan Africa.

PARTICIPANTS

Women aged 15-64 years.

OUTCOME MEASURES

Socioeconomic inequalities in cervical cancer screening uptake and the pooled prevalence of cervical cancer screening.

RESULTS

The pooled prevalence of cervical cancer screening among women in sub-Saharan African countries was 10.51% (95% CI: 7.54% to 13.48%). Cervical cancer screening uptake showed a significant pro-rich distribution of wealth-related inequalities, with a weighted Erreygers normalised concentration index of 0.084 and an SE of 0.003 (p value <0.0001). This finding suggests that disparities in cervical cancer screening uptake among women are related to wealth. Decomposition analysis revealed that the wealth index, educational status, place of residence and media exposure were the most important factors contributing to this pro-rich socioeconomic inequality in cervical cancer screening.

CONCLUSION

This study emphasises the importance of addressing modifiable factors such as improving educational opportunities, increasing media exposure accessibility in households and improving the country's economy to reduce wealth disparities and improve cervical cancer screening uptake among women.

Spatial distribution and characteristics of women reporting cervical cancer screening in Malawi: An analysis of the 2020 to 2021 Malawi Population-based HIV Impact Assessment survey data

BACKGROUND

Malawi has one of the highest incidence and mortality rates of cervical cancer in the world. Despite a national strategic plan and the roll-out of VIA and screen-and-treat services, cervical cancer screening coverage in Malawi remains far below the national target.Using a nationally representative sample of women enumerated in the Malawi Population-based Impact Assessment (MPHIA) survey we estimated the prevalence and spatial distribution of self-reported cervical cancer screening as a proxy for uptake in Malawi.

METHODS

MPHIA was a nationally representative household survey in Malawi, targeting adults aged 15 and above, that employed a cross-sectional, two-stage, cluster design. The primary aim of MPHIA was to assess the regional prevalence of viral load suppression and the progress towards achieving the UNAIDS 95-95-95 goals among adults aged 15 and above. The survey was carried out between January 2020 and April 2021. Prevalence of self-reported cervical cancer screening by different characteristics was estimated accounting for the survey design using the Taylor series approach. We used univariable and multivariable logistic regression approaches to examine associations between the prevalence of cervical cancer screening and demographic characteristics.

FINDINGS

A total of 13,067 adult (15 years and older) female individuals were surveyed during the MPHIA 2020 to 2021 survey, corresponding to a weighted total of 5,604,578. The prevalence of self-reported cervical cancer screening was 16.5% (95% CI 15.5-18.0%), with women living with HIV having a higher prevalence of 37.8% (95% CI 34.8-40.9) compared to 14.0% (95% CI 13.0-15.0) in HIV negative women. The highest prevalence of screening was reported in the Southwest zone (SWZ) (24.1%, 95% CI 21.3-26.9) and in major cities of Blantyre (25.9%, 95% CI 22.9-29.0), and Lilongwe (19.6%, 95% CI 18.0-21.3). Higher self-reported screening was observed in women who resided in urban regions ((22.7%; 95% CI 21.4-24.0) versus women who resided in rural areas (15.2%; 95% CI 14.0-16.8). Cervical cancer screening was strongly associated with being HIV positive (aOR 2.83; 95% CI 2.29-3.50), ever having been pregnant (aOR 1.93; 95% CI 1.19-3.14), attaining higher education level than secondary education (aOR 2.74; 95% CI 1.67-4.52) and being in the highest wealth quintile (aOR 2.86; 95% CI 2.01-4.08).

INTERPRETATION

The coverage of cervical cancer screening in Malawi remains low and unequal by region and wealth/education class. Current screening efforts are largely being focussed on women accessing HIV services. There is need for deliberate interventions to upscale cervical cancer screening in both HIV negative women and women living with HIV.

Factors Associated With Cervical Cancer Screening Attendance in Hungary Based on the European Health Interview Survey

Objectives

This study assessed the change in cervical cancer screening attendance across 10 years and identified the associated factors.

Methods

Data from the European Health Interview Surveys in Hungary (2009, 2014, 2019) were analyzed with multivariate and multiple logistic regressions.

Results

The analysis involved 4,850 participants, revealing a significant (p < 0.001) increase in screening attendance from 69% to 77% over 10 years. Factors significantly associated with higher attendance rates included a higher education level (tertiary level AOR = 2.51 [2.03-3.09]), being in a relationship (AOR = 1.59 [1.39-1.83]), the belief that one can do much for one's health (OR = 1.26 [1.05-1.52]), and the absence of chronic health problems (AOR = 1.56 [1.33-1.84]). Lower screening odds were significantly correlated with worse self-perceived health status (AOR = 0.65 [0.52-0.81]) and less frequent doctor (AOR = 0.64 [0.54-0.76]) and specialist visits (AOR = 0.46 [0.39-0.53]).

Conclusion

Enhancing cervical cancer screening rates requires tailored public health strategies, particularly targeting individuals with lower education and poor health perceptions. Public health initiatives and enhanced collaboration among healthcare professionals are required to further increase participation rates, particularly among the identified groups.

Disparities and Determinants of Testing for Early Detection of Cervical Cancer among Nepalese Women: Evidence from a Population-Based Survey

BACKGROUND

Cervical cancer presents a considerable challenge in South Asia, notably in Nepal, where screening remains limited. Past research in Nepal lacked national representation and a thorough exploration of factors influencing cervical cancer screening, such as educational and socioeconomic disparities. This study aims to measure these gaps and identify associated factors in testing for early detection of cervical cancer among Nepalese women.

METHODS

Data from the 2019 Nepal Noncommunicable Disease Risk Factors survey (World Health Organization STEPwise approach to noncommunicable risk factor surveillance), involving 2,332 women aged 30 to 69 years, were used. Respondents were asked if they had undergone cervical cancer testing through visual inspection with acetic acid, Pap smear, or human papillomavirus test ever or in the past 5 years. The slope index of inequality (SII) and relative concentration index were used to measure socioeconomic and education-based disparities in cervical cancer test uptake.

RESULTS

Only 7.1% [95% confidence interval (CI): 5.1-9.9] Nepalese women had ever undergone cervical cancer testing, whereas 5.1% (95% CI: 3.4-7.5) tested within the last 5 years. The ever uptake of cervical cancer testing was 5.1 percentage points higher (SII: 5.1, 95% CI: -0.1 to 10.2) among women from the richest compared with the poorest households. Education-based disparities were particularly pronounced, with a 13.9 percentage point difference between highly educated urban residents and their uneducated counterparts (SII: 13.9, 95% CI: 5.8-21.9).

CONCLUSIONS

Less than one in ten women in Nepal had a cervical cancer testing, primarily favoring higher educated and wealthier individuals.

IMPACT

Targeted early detection and cervical cancer screening interventions are necessary to address these disparities and improve access and uptake.

Drivers of breast cancer and cervical cancer screening among women of reproductive age: insights from the Ghana Demographic and Health Survey

BACKGROUND

The two major causes of cancer-related deaths among women in Ghana are breast cancer (BC) and cervical cancer (CC). These types of cancers typically do not show any symptoms until they have progressed. Therefore, it is important to screen for early detection. This research aimed to investigate the rate of breast cancer and cervical cancer screening, as well as the factors associated with it, among women of reproductive age in Ghana.

METHODS

This study analysed data from the 2022 Ghana Demographic and Health Survey. A total of 15,014 women aged 15 to 49 years were included in the analysis. Descriptive statistics and binary logistic regression were employed to analyse the data with the aid of STATA/SE, version 17.

RESULTS

It was found that 18.4% and 5.0% of the women had screened for BC and CC, respectively. Women aged 45-49 years were about three times more likely (aOR = 2.83, 95% CI: 1.88-4.24) to screen for BC compared to those aged 15-19 years. Women who had tested for HIV had increased odds (aOR = 1.88, 95% CI: 1.56-2.25) of screening for BC compared to their counterparts. Women within the richest wealth index (aOR = 1.95, 95% CI: 1.40-2.72) had increased odds of screening for BC compared to those in the poorest wealth index. Regarding CC screening, women with higher education (aOR = 2.56, 95% CI: 1.53-4.29) were two times more likely to screen for CC compared to those with no formal education. Women who did not use tobacco (aOR = 0.45, 95% CI: 0.21-0.96) had decreased odds of CC screening compared to their counterparts.

CONCLUSIONS

This study showed that the uptake of BC and CC screening services among women in Ghana was very low. The drivers of BC and CC screening included enabling, predisposing, and need factors. Stakeholders can leverage the mass media to raise awareness and educate women in reproductive age about the importance of BC and CC screening. This study provides relevant information that can inform BC and CC policies and programmes in Ghana.

Ethnic inequalities in coverage and use of women's cancer screening in Peru

OBJECTIVE

This study aimed to assess ethnic inequalities in the coverage and utilization of cancer screening services among women in Peru.

METHODS

Data from the 2017-2023 Demographic and Family Health Survey in Peru were analyzed to evaluate ethnic disparities in screening coverage for breast and cervical cancer, including clinical breast examination (CBE), Pap smear test (PST), and mammography. Measures such as the GINI coefficient and Slope Index of Inequality (SII) were used to quantify coverage and utilization disparities among ethnic groups.

RESULTS

The study included 70,454 women aged 30-69. Among women aged 40-69, 48.31% underwent CBE, 84.06% received PST, and 41.69% underwent mammography. It was found inequalities in coverage for any cancer screening (GINI: 0.10), mammography (GINI: 0.21), CBE (GINI: 0.19), and PST (GINI: 0.06), in 25 Peruvian regions. These inequalities were more pronounced in regions with larger populations of Quechua, Aymara, and Afro-Peruvian women. In rural areas, Quechua or Aymara women (SII: -0.83, -0.95, and - 0.69, respectively) and Afro-Peruvian women (SII: -0.80, -0.92, and - 0.58, respectively) experienced heightened inequalities in the uptake of CBE, mammography, and PST, respectively. Like Quechua or Aymara women (SII: -0.50, SII: -0.52, and SII: -0.50, respectively) and Afro-Peruvian women (SII: -0.50, SII: -0.58, and SII: -0.44, respectively) with only a primary education.

CONCLUSION

Ethnic inequalities affect breast and cervical cancer screening coverage across regions in Peru. In Quechua, Aymara, and Afro-Peruvian women the uptake of mammography, CBE, and PST was less frequently than their white or mestizo counterparts. These inequalities are attributed to sociodemographic conditions such as lower education levels and residence in rural or non-capital areas.

What rate of Iranian women perform Pap smear test? Results from a meta-analysis

In this study, an attempt was made to estimate the aggregated proportion of Pap smear test uptake among women in Iran from 2012 to 2022 using meta-analysis. The data collection process involved reviewing records registered in databases between January 1, 2012, and September 11, 2022. The final data was analyzed using random effects models, and potential heterogeneity was assessed using the I2 index. To examine publication bias, Egger's test and Funnel Plot were employed. Sensitivity analysis, specifically single study exclusion Meta-analysis, was conducted to assess the influence of each individual study on the aggregated percentage of Pap smear test uptake. A total of 28,754 women were included across the 33 articles analyzed. The pooled percentage of Pap smear test uptake for both one-time and regular screenings was found to be 46.52% (95% CI: 40.91 to 52.14) and 17.80% (95% CI: 12.42 to 23.18), respectively. No significant evidence of publication bias was detected, although the influence of smaller studies was confirmed. Sensitivity analysis indicated that the overall rate of Pap smear test uptake was not highly sensitive to the results of individual studies. The findings emphasize the low rate of regular Pap smear testing among Iranian women and suggest that tailored interventions considering cultural and geographical factors specific to different provinces in Iran could help increase the utilization of this screening service.

Self-Reported Cervical Cancer Screening Uptake Among Women of Reproductive Age in Zambia: Evidence from the 2021 Zambia Population-Based HIV Impact Assessment (ZAMPHIA) Survey

BACKGROUND

Despite Zambia implementing the World Health Organisation's (WHO) tri-pillar cervical cancer prevention goals 90-70-90 Prevent, Screen, and Treat, cervical cancer claims 2000 lives annually and reigns as the most common cancer among women, especially those living with HIV (WLHIV). Our study describes the national uptake of screening and treatment from the ZAMPHIA 2021 survey.

METHODS

Utilising a two-stage cluster sampling approach, the study included participants aged 15 years and older across Zambia's ten provinces. Data were collected on demographic traits, reproductive history, sexual behaviour, and cervical cancer prevention using a structured questionnaire, and HIV was diagnosed from biological samples. Women aged 15-49 were eligible for inclusion in the analysis. The primary outcome of interest was whether a woman self-reported being screened for cervical cancer. Sociodemographic characteristics were calculated for categorical variables using the SAS proc surveyfreq procedure, producing both raw and weighted estimates. The weighted estimates and their variance were generated using jackknife replicate weights for each record.

RESULTS

Of the 8801 surveyed women, 22.2% reported undergoing cervical cancer screening, the majority being aged between 35-49 years. Cervical cancer screening uptake was more likely among compared to HIV negative counterparts (aOR = 3.92, 95% CI: 3.10, 4.95), those aged 25-34 years (aOR = 1.76, 95% CI: 1.42, 2.21) or 35-49 years (aOR = 2.65, 95% CI: 2.11, 3.33) than younger and those with 1-4 (aOR = 2.16, 95% CI: 1.54, 3.02) or more than 5 live births (aOR = 1.98, 95% CI: 1.37, 2.87) than none. Marital status, WLHIV, education, and parity were other factors significantly associated with screening.

CONCLUSION

We report low cervical cancer screening uptake compared to the 70% target of WHO. The WHO's call for bolstered strategies and efforts to increase cervical cancer screening and treatment is timely and urgent. Therefore, ongoing messaging and health education among all women is key.

Association of plasma aflatoxin with persistent detection of oncogenic human papillomaviruses in cervical samples from Kenyan women enrolled in a longitudinal study

BACKGROUND

Cervical cancer is caused by oncogenic human papillomaviruses (HR-HPV) and is common among Kenyan women. Identification of factors that increase HR-HPV persistence is critically important. Kenyan women exposed to aflatoxin have an increased risk of HR-HPV detection in cervical specimens. This analysis was performed to examine associations between aflatoxin and HR-HPV persistence.

METHODS

Kenyan women were enrolled in a prospective study. The analytical cohort for this analysis included 67 HIV-uninfected women (mean age 34 years) who completed at least two of three annual study visits and had an available blood sample. Plasma aflatoxin was detected using ultra-high pressure liquid chromatography (UHPLC)-isotope dilution mass spectrometry. Annual cervical swabs were tested for HPV (Roche Linear Array). Ordinal logistic regression models were fitted to examine associations of aflatoxin and HPV persistence.

RESULTS

Aflatoxin was detected in 59.7% of women and was associated with higher risk of persistent detection of any HPV type (OR = 3.03, 95%CI = 1.08-8.55, P = 0.036), HR-HPV types (OR = 3.63, 95%CI = 1.30-10.13, P = 0.014), and HR-HPV types not included in the 9-valent HPV vaccine (OR = 4.46, 95%CI = 1.13-17.58, P = 0.032).

CONCLUSIONS

Aflatoxin detection was associated with increased risk of HR-HPV persistence in Kenyan women. Further studies, including mechanistic studies are needed to determine if aflatoxin synergistically interacts with HR-HPV to increase cervical cancer risk.

Socio-demographic determinants of cervical cancer screening uptake among women of child-bearing age in Mangochi, Malawi: a facility-based cross-sectional study

Background

Cervical cancer (CC) is the number one leading cause of death among women in Malawi. However, it is generally viewed as preventable and treatable if diagnosed in an early stage. Despite the burden, Malawi registers low uptake of cervical cancer screening (CCS). This study examined the socio-demographic determinants of CCS uptake among women of child-bearing age (WCBA) in Mangochi district.

Methods

A cross-sectional quantitative study was conducted in five health facilities. A total of 482 women between the ages of 18–49 participated and were sampled using a multi-stage sampling method. An interviewer administered structured questionnaire was used to collect data from June to July, 2019. Multivariate logistic regression model was used to identify determinants of CCS uptake among WCBA.

Results

Few respondents (13.1%) had ever done CCS. Compared to respondents in the age-group of 18–24 years, those in the age-groups of 25–35 years and 36–49 years were 2.63 and 3.90 times more likely to undergo CCS (AOR = 2.63, 95% CI 1.30–5.31 and AOR = 3.90, 95% CI 1.62–9.38), respectively. Respondents who practiced Christianity were 2.77 times more likely to undergo CCS than those who practiced Islam (AOR = 2.77, 95% CI 1.23–6.22). Respondents of the Chewa ethnic group were 71% less likely to undergo CCS as compared to those of Yao ethnicity (AOR = 0.29, 95% CI 0.09–0.95). Respondents who lived in semi-urban areas were 2.57 times more likely to go for CCS than those who were village residents (AOR = 2.57, 95% CI 1.19–5.55).

Conclusion

Our study showed that CCS uptake was low in Mangochi and the results suggested that age, religion, ethnicity and place of residence were determinants of CCS uptake. We recommend that comprehensive health education on CC should specifically target the young women and Muslim women in places where they meet. We call upon the district health authorities to scale up CCS provision in all Antiretroviral Therapy (ART) and outreach clinics to improve CCS uptake among women residing in the villages and those of the Chewa ethnicity. We, further, call upon all CC program implementers to design programs that address the highlighted socio-demographic determinants of CCS uptake among WCBA in the district.
