Background: It is possible to prevent deaths due to cervical cancer through screening and treatment. Cervical cytology which is a standard screening tool in developed countries fails as a screening method in low-resource countries due to financial and technical constraints. Objective: To determine the prevalence of pre-malignant lesions of the cervix by VIA and Pap smear test among rural married women and to find out association of socio demographic factors with positive screening test results. Method: A community based cross-sectional study was carried out among rural married women in the field practice area of a tertiary health care center. A pre-designed questionnaire was administered to collect information on socio-demographic characteristics from 550 women. They were tested for the presence of pre-malignant lesions of the cervix using VIA and Pap smear as screening tools. Results: Out of 550 study participants, total 37 patients were found positive, out of which 7, 17 & 13 patients were found positive by Pap smear alone, VIA test alone, and by both these tests respectively. Moderate agreement (k=0.498) was found between these two tests by applying Kappa statistics at 95% confidence interval. The VIA and Pap smear tests were positive among 5.5% and 3.6% study subjects respectively. The positivity rate was found to be more in the age group of >50 years, Hindu, SC/ST caste, joint family, professional and, upper class. Conclusion: The prevalence of pre-malignant lesions of the cervix by VIA test was 5.5% while 3.6% pre-malignant lesion was detected by Pap smear method. VIA and Pap smear positivity rates among rural married women.

| Introduction|| |
Cervical cancer in India is the second-most common cancer in women (12.1%). Every year, around 1.23 lakh new women are diagnosed with cervical cancer and 67,500 of these women die of the disease in India (Globocan 2012).
Cervical cancer is a preventable disease as it can be diagnosed in its precancerous stage. Screening by cervical cytology is the most common method used in developed country for detection of the disease in an early stage. The cytology screening program has failed in developing world due to financial constraints, lack of political will, poor organizational backup, lack of expertise, and lack of prioritization. Prompted by the need for optimal strategies of cervical screening in low resource settings, the role of Pap smear More Details examination and visual inspection of the cervix with acetic acid (VIA) has been widely studied. These techniques are less expensive and simpler to perform and can be mastered in a short period by the health workers. They can provide the results immediately which make them suitable for the wide screening in regions with a high incidence of cervical cancer.
At present, National Program for the Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases, and Stroke is also started to enable opportunistic screening for cervical cancer by VIA, at District, and community health centers levels, through the setting up of non-communicable disease clinics.
Cervical cancer has a major impact on woman's lives worldwide and most of the cervical cancer cases are diagnosed late leading to poor outcomes. The women are examined, especially vagina, by conducting the VIA and Pap smear method to detect precancerous lesions to allow early treatment and thus prevent these from evolving into cancerous lesions.
Very few such studies have been done in India, Uttar Pradesh and none in Rohilkhand region, to detect premalignant lesions of the cervix using VIA or Pap smear. Hence, considering the above-mentioned facts, the present study was carried out at Rural Health Training Centre, of a medical college from this region.
Aim and objectives
- To conduct VIA and Pap smear examination of eligible married women of rural area
- To find out socio-demographical factors associated with positive screening test results.
| Materials and Methodology|| |
The present cross-sectional study was carried out during 2014–2016 in the area of Rural Health Training Centre, under the Department of Community Medicine. The study protocol was reviewed and approved by institutional review and ethics committees. A sample size of 550 patients was selected for an estimated prevalence 12% of premalignant lesions of cervix in the Hegde et al. and assumed relative error was 23%, the precision was found 2.72%.
The rural health training center (RHTC) comprised of 24 villages, of which, one village Dhaura was randomly selected in the first stage. The second stage of sampling was done for selection of households. All the houses of the selected village were numbered and 1st house was randomly selected by drawing a random number. Thereafter, consequent houses were visited for the collection of the data. All the eligible study participants present during the visit in those household were studied. The subject were explained the symptoms, risks of cervical cancer, and benefits of screening test. They were motivated to undergo gynecological check-up including VIA and Pap Smear test. Those who consented were administered questionnaire comprising of sociodemographic history.
After filling the questionnaire, the eligible women were given date and time to visit outpatient department at RHTC for per speculum examination. Per speculum examination was done to visualize the cervix, the external os was identified with pinkish squamous epithelium and reddish columnar epithelium and transformation zone. The condition of the cervix and vagina was noted down.
Rural married Women, who give consent for the study.
Pregnancy women with posthysterectomy status, active vaginal bleeding, seriously ill and those not willing to participate in the study.
Pap smear and visual inspection of the cervix with acetic acid test
First, Pap smear test was done on the subject. Pap smear was taken from two samples from ecto/endo cervix. The Pap smear slide was immediately fixed with a mixture of 50% ethyl alcohol and 50% ether. Thereafter, each woman was subjected to VIA. Using a cotton swab soaked in 5% acetic acid for 1–2 min and then the cervix was carefully inspected for any acetowhite lesions, particularly in the transformation zone. The test outcome was considered positive if any distinct acetowhite area was detected on the cervix. If no acetowhite lesions areas were detected or if the whitish appearance was doubtful or faint, the test was scored as negative.
Reporting of the slide was done according to Bethesda Classification  which is as follows:
- NILM – Negative for intraepithelial lesions or malignancy, ASCUS-Atypical squamous cells of undetermined significance, LSIL – Low-grade squamous intraepithelial lesions, and HSIL – High grade squamous intraepithelial lesions.
Data compilation and analysis
Data were entered into excel spreadsheet. It was compiled, and analysis was done with the help of percentages and Chi-square test.
| Results|| |
Out of 550 study participants, 37 patients were positive, out of which 7 patients were positive by Pap smear alone, 17 patients by VIA test alone, and 13 patients by both tests. Kappa statistics at 95% confidence interval was 0.498 indicating moderate agreement [Table 1]. Positivity rates were progressively increasing with age and the associations between positivity rates with age group was highly statistically significant (P< 0.05). Positivity rates among Hindus (9.8%) were more than Muslim (2.9%) subjects and the association between positivity rate and religion was statistically significant. The positivity rates were reported 12.7%, 6.8%, and 5.6% among SC/ST, general caste, and OBC caste, respectively and the association with caste was not significant (P > 0.05). Majority individuals were illiterate 257 (46.7%). In general, positivity rate of screening tests increases as literacy rate increases, but in this study, high positivity rate was reported in the individuals of intermediate and above education (18.2%) while low among illiterates (3.9%) and primary school (2.7%) and the association was found statistically significant. The positivity rates were significantly high among un-skilled (26.1%) and professional group (20.0%) than other group of occupation. Positivity rate among joint family subjects (22.2%) was high in comparison to nuclear family (6.5%) and the association was not significant.

| Discussion|| |
In this present study, the VIA positivity rate was found to be 5.5% and Pap smear positivity rate was 3.6%. Results of the present study are aligned with Makuza et al., who reported VIA positivity to be 5.9%. However, the hospital based study carried out by Hegde et al., in Karnataka showed very high VIA and Pap smear positivity rate (12% and 11.5%). This may be due to the regional variation, difference in methodology adopted and difference in the age group taken for the study.
The present study depicted that VIA positivity rate was highest in the age group above 40 years. Results of the present study show that VIA and Pap smear positivity rate increases with the age (P<.001). Similar results were also found in Bhattacharyya et al. and MakuzaJ. D., et al. study, in which the VIA positivity rate was also found to be highest in the age group of 40 years and above.
VIA and Pap smear positivity rate was higher in Hindus (7.5% and 5.5%) than Muslims (2.9% and 1.2%) (P< 0.01). The higher prevalence in Hindu was also reported by Paul et al. study. The lower prevalence of Ca cervix in this present study in Muslim population may be due to the ritual of circumcision in males among Muslims.
Surprisingly, VIA positivity rate was highest in women educated up to intermediate and above but number of study subjects in these group was very low. No statistically significant association between VIA positivity rate and educational level has been seen in this present study (P > 0.05). The same pattern of VIA positivity rate was also reported by the Bhattacharyya et al.
No VIA and Pap smear positive cases were found in professional and unskilled groups in the present study. This may be because of very low number of study subjects in these two occupational groups. VIA positivity rate was relatively higher in women belonging to clerical/shopkeeper/farmer group (P< 0.01). However, Pap smear positivity was highest in semi-skilled groups.
There were less VIA and Pap smear positive cases found in study subjects residing in the nuclear family in the present study. Higher VIA positivity rate (33.3%) and Pap smear positivity (11.1%) was observed in subjects of the joint family. The possible factors may be illiteracy, ignorance, and low socioeconomic status for such pattern (P< 0.01).
In this present study, there were very few study participants in upper class with a high Pap smear positivity rate of (25.0%). Similar observation had been seen in Mhaske et al. study in which the Pap smear positivity rate was high (33.3%) in upper-class socioeconomic status (P< 0.001). Their study too showed statistically significant association between the socioeconomic status and cervical dysplasia.
| Conclusion|| |
In this study, the prevalence of premalignant lesions of the cervix among rural married women was 5.5% and 3.6% by VIA and Pap smear test, respectively. The degree of agreement between these two tests was moderate. As there is no baseline data on prevalence of premalignant lesions of the cervix among women from this area, further research studies are needed in this direction.
The investigator found it difficult to convince the women for cervical screening as many women did not give consent due to poor awareness, social stigma and fear associated with the diagnosis of cancer.
