Human Papillomavirus, Related Diseases, and Vaccination: Knowledge and Awareness Among Health Care Students and Professionals in Nepal.

Human papillomavirus (HPV) is a common sexually transmitted disease worldwide. While burden of HPV-associated cancers and mortality is higher in low-income countries, there is limited data about knowledge of it among health care students and professionals. We assessed awareness and knowledge of HPV, its related diseases, and HPV vaccine among 333 participants, composed of 146 medical students (MSs) and professionals (MPs) and 187 nursing students (NSs) and professionals (NPs) using a 40-question survey between July 2018 and February 2019. Surveys were conducted in English language using both paper and an online version. Most participants reported that they had heard of HPV and cervical cancer. However, 91.76% of MPs and 77.97% of MSs, but only 41.11% of NPs and 36.17% NSs reported knowing that HPV types 16 and 18 caused cervical cancer. Likewise, about two-thirds of MPs and MSs reported having the knowledge that HPV 6 and 11 caused genital warts versus only a little over one-fourth of NPs and NSs. Only 55.91% of NPs and 51.61% of NSs were aware that HPV could cause cancer in both men and women, whereas 42.35% of MPs, 64.41% of MSs, 41.76% of NPs, and 40.66% of NSs were aware that the vaccine could be given to both boys and girls. While medical professionals were relatively more knowledgeable about HPV and related diseases, overall, knowledge about the HPV vaccine was low among all groups. This knowledge gap is concerning and warrants further attention to fight HPV-related public health burden in Nepal.

Perception and practices of menstruation restrictions among urban adolescent girls and women in Nepal: a cross-sectional survey.

BACKGROUND: Menstruation, a natural biologic process is associated with restrictions and superstitious beliefs in Nepal. However, factual data on women's perspectives on menstrual practices and restrictions are scarce. This study aimed to assess socio-cultural perceptions of menstrual restrictions among urban Nepalese women in the Kathmandu valley. METHODS: Using a clustered random sampling, 1342 adolescent girls and women of menstruating age (≥15 years) from three urban districts in the Kathmandu valley completed a survey related to menstrual practices and restriction. This was a cross-sectional survey study using a customized program allowing pull-down, multiple choice and open-ended questions in the Nepali language. The self-administered questionnaire consisted of 13 demographic questions and 22 questions related to menstruation, menstrual hygiene, socio-cultural taboos, beliefs and practices. Univariate descriptive statistics were reported. Unadjusted associations of socio-cultural practices with ethnicity, education, four major social classes, three major religions, marital status and family type were assessed using logistic regression models. RESULTS: More than half (59%) of the participants were aged between 15- < 25 years. The majority were Hindus (84.5%), reported not praying during menstruation (83.1%) and were encouraged by their mothers (72.1%) to practice a range of menstrual restrictions. Purifying either the kitchen, bed, bedsheets or other household things on the fourth day of menstruation was reported by 66.1% of the participants, and 45.4% saw menstruation as a "bother" or "curse." There were differences among social classes, where participants of the Janajati caste, an indigenous group, were more likely to enter places of worship [OR (95%CI): 1.74 (1.06-2.86)] and pray [OR (95%CI): 1.79 (1.18-2.71)] while menstruating, compared to the Brahmins. Participants with a master's degree were more likely to pray while menstruating, compared to participants with less than a high school education [OR (95%CI): 2.83 (1.61-4.96)]. CONCLUSION: This study throws light on existing social discriminations, deep-rooted cultural and religious superstitions among women, and gender inequalities in the urban areas of Kathmandu valley in Nepal. Targeted education and awareness are needed to make changes and balance between cultural and social practices during menstruation.

Cervical Cancer and Human Papillomavirus Vaccine Awareness Among Married Bhutanese Refugee and Nepali Women in Eastern Nepal.

This study examined the sexually transmitted infections (STIs), cervical cancer, and human papillomavirus virus (HPV) vaccine-related awareness and knowledge among married Bhutanese refugee and Nepali women living in eastern Nepal. Participants were recruited from a women's health camp in Jhapa District in eastern Nepal. A demographic and health survey with questions on STIs, cervical cancer and HPV vaccine was administered to consenting participants. Women who were born in Bhutan or living in the United Nations administered refugee camps were classified as Bhutanese. Of the 630 participants, 14.3% of participants were Bhutanese and the mean age was 38.8 ± 8.2 years. A higher proportion of Bhutanese than Nepali women reported a lack of cervical cancer awareness (42.0% vs. 30.7%; p = 0.036). Only 21.5% of the participants knew HPV as the cause of cervical cancer; 13.9% were aware of an HPV vaccine; and 96% reported that they would have their children vaccinated against HPV if the vaccine was available free of cost to them. In multivariable analyses, the lack of awareness about STIs was directly associated with the lack of cervical cancer awareness [odds ratio (OR) 4.50; 95% confidence interval (CI) 2.99-6.77] and inversely associated with HPV-vaccine awareness [OR 0.53; 95% CI 0.29-0.97]. Low cervical cancer and HPV vaccine awareness and knowledge among Nepali and Bhutanese women in eastern Nepal highlight the need for increasing awareness and knowledge in the context of STIs and reproductive health education. Increasing awareness and knowledge of HPV, its role in cervical cancer, and prevention modalities is a first critical step for implementing successful targeted primary cervical cancer prevention measures focused on behavior modification and vaccine administration.

High-risk human papillomavirus infection and abnormal cervical cytology among Nepali and Bhutanese refugee women living in eastern Nepal.

BACKGROUND: Cervical cancer is the leading cause of cancer morbidity and mortality among women in Nepal and Bhutan. Data on high-risk human papillomavirus (HR-HPV) infection and cervical abnormalities among Nepali and Bhutanese women are sparse. The objectives of this study were to assess and compare the prevalence of HR-HPV infection and cervical abnormalities among Nepali and Bhutanese women living in Jhapa District in eastern Nepal; and examine the risk factors for HR-HPV infection and cervical abnormalities in those women. METHODS: Study participants were recruited from a women's health camp organized by NFCC-International, a Nepal-based non-governmental organization, in 2014. Consenting participants were administered a demographic and health questionnaire and cervico-vaginal specimens collected. Both self-collected and clinician-collected cervico-vaginal specimens were tested for HR-HPV infection. Cytologic exam was performed on clinician-collected samples and cervical cytology results were categorized according to the Bethesda classification. A participant was classified as a Bhutanese if they were either born in Bhutan or currently lived in one of the United Nations administered Bhutanese refugee camps in Jhapa; otherwise, the participant was classified as a Nepali. RESULTS: Of the 647 study participants, 15.9% were Bhutanese women living in refugee camps and the overall age (± standard deviation) was 38.8 ± 8.2 years. The prevalence of HR-HPV infection was 8.9% and abnormal cervical cytology was 7.1% respectively, with no significant difference in HR-HPV positivity (p = 0.399) or abnormal cervical cytology (p = 0.698) between Nepali and Bhutanese women. Compared to women whose husbands had not migrated for employment, women whose husbands had migrated outside of the district had 3.30 times (95% Confidence Interval [CI]: 1.13-9.64) the odds of being HR-HPV positive and women whose husbands had migrated outside the country had 2.92 times (95% CI: 1.32-6.49) the odds of having abnormal cervical cytology. CONCLUSIONS: HR-HPV positivity and abnormal cervical cytology were similar among Nepali and Bhutanese women. Husbands migrating for employment within or outside the country was a significant risk factor for high-risk HPV infection and cervical cytology, indicating the important role spousal behavior may play in HR-HPV acquisition and cervical abnormalities among these women.

Genomic diversity and phylogenetic relationships of human papillomavirus 16 (HPV16) in Nepal.

OBJECTIVES/BACKGROUND: Sequence variants in HPV16 confer differences in oncogenic potential; however, to date there have not been any HPV sequence studies performed in Nepal. The objective of this study was to characterize HPV16 viral genome sequences from Nepal compared to a reference sequence in order to determine their lineages. Additionally, we sought to determine if five High-grade Squamous Intraepithelial Lesion (HSIL) subjects were genetically distinct from the non-HSIL subjects. METHODS: DNA was isolated from exfoliated cervical cells from 17 individuals in Nepal who were previously identified to be HPV16-positive. A custom HPV16 Ion Ampliseq panel of multiplexed degenerate primers was designed that generated 47 overlapping amplicons and covered 99% of the viral genome for all known HPV16 variant lineages. All sequence data were processed through a custom quality control and analysis pipeline of sequence comparisons and phylogenetic analysis. RESULTS: There were high similarities across the genomes, with two major indels observed in the non-coding region between E5 and L2. Compared to the PAVE reference HPV16 genome, there were up to 9, 4, 38, 27, 8, 7, 52, and 32 nucleotide variants in the E6, E7, E1, E2, E4, E5, L2, and L1 genes in the Nepalese samples, respectively. Based on sequence variation, HPV16 from Nepal falls across the A, C, and D lineages in this study. We found no evidence of genetic distinctness between HSIL and non-HSIL subjects. CONCLUSIONS: The evolutionary and pathological characteristics of the representative HPV16 genomes from Nepal seem similar to results from other parts of the world and provide the basis for further studies.
