Identifying Risk Factors for Lower Reproductive Tract Infections among Women Using Reusable Absorbents in Odisha, India

Decomposing the rural-urban gap in hygienic material use during menstruation among adolescent women in India

The use of hygienic materials (sanitary napkins, locally prepared napkins, tampons, and menstrual cups) during menstruation among adolescent women in India has improved over the years, yet a significant rural-urban gap in the usage persists at the national level. This study investigates how this rural-urabn gap varies across different states and union territories (UTs) of India and uses Fairlie decomposition to quantify the contribution of various factors to this gap. The study uses data on 114,805 adolescent women (aged 15-19 years) from the fifith round of National Family Health Survey (2019-21). The utilization of hygienic materials during menstruation among adolescent women in rural India stood at 43%, whereas in urban areas, it was 68%, indicating a significant 25 percentage point (pp) difference between the two. The rural-urban gap in the hygienic material use varied significantly across Indian states and UTs. The gap exceeded 20 pp in Madhya Pradesh (36 pp), Odisha (26 pp), Jammu and Kashmir (25 pp), Assam (25 pp), Uttar Pradesh (23 pp), Jharkhand (22 pp), Chhattisgarh (21 pp), and Rajasthan (21 pp). In contrast, the gap in Tamil Nadu, Himachal Pradesh, and Telangana was less than 10 pp. The decomposition analysis of the rural-urban gap (25 pp) revealed that the variables included in the anlaysis explained about 70% of the gap. The difference in the household wealth between rural and urban areas contributed about 69% of the explained gap. Other significant contributors to the explained gap were 'transportation to health facility' (5.6%), 'mass-media exposure' (4.9%), and 'level of education (4.4%). The findings underscore the necessity for state-specific interventions aimed at vulnerable groups, particularly individuals from economically disadvantaged backgrounds, those with lower levels of education, and limited exposure to mass media, in order to reduce the existing rural-urban disparity in hygienic material use among adolescent women.

Assessing the link between hygienic material use during menstruation and self-reported reproductive tract infections among women in India: a propensity score matching approach

Background

Reproductive tract infections (RTIs) present a substantial health concern for women, especially in developing nations such as India, where inadequate access to proper sanitation and hygiene facilities frequently results in suboptimal menstrual health and hygiene (MHH), exacerbating the risk of RTIs. In this study, we analysed the self-reported prevalence of RTIs among young women in India and evaluated the impact of hygienic menstrual material usage on these RTIs.

Methods

The study used information on 27,983 women aged 15-24 years, from the National Family Health Survey (NFHS-5) (2019-21). The prevalence of RTIs was calculated for all the states and UTs of India, and propensity score matching (PSM) technique was used to evaluate the impact of hygienic material use on RTIs among women in India.

Results

Every four out of 100 women reported RTIs in India in 2019-21. Notably, RTI prevalence displayed substantial state-level disparities. West Bengal exhibited the highest RTI prevalence at 9.3%, followed by Meghalaya, Arunachal Pradesh, and Himachal Pradesh, all surpassing 6%. In contrast, the lowest RTI rates were recorded in Puducherry at 0.9%, succeeded by Andaman and Nicobar Islands, Odisha, and Jammu & Kashmir, all registering rates below 2%. The PSM analysis revealed that women who utilized hygienic materials during menstruation exhibited a reduced prevalence of RTIs (referred to as the "treated group" with an Average Treatment Effect on the Treated (ATT) of 0.0315) compared to those who did not utilize such materials (referred to as the "control group" with an ATT of 0.0416).

Conclusions

The study underscores the critical significance of using hygienic materials during menstruation as a preventive measure against RTIs among women in India. The findings suggest the need for targeted interventions focused at promoting hygienic menstrual materials to reduce the prevalence of RTIs among women in India.

Assessment of Symptoms and Risk Factors as a Screening Tool of Bacterial Vaginosis Among Reproductive Age-Group Females in West Bengal, India

Background Bacterial vaginosis (BV) is a ubiquitous vaginal discomfort and has overlapping symptoms with other reproductive tract infections. The World Health Organization suggested a symptomatic approach for diagnosing BV with insufficient laboratory setup. However, due to symptom overlap, BV is often misled and ends up with injudicious drug application. Objective The study aims to identify the most relevant symptoms and behavioral risk factors associated with BV in tertiary healthcare settings in West Bengal, India. It also seeks to develop a scoring system based on clinical symptoms to screen for BV, especially when laboratory facilities are limited. Methodology The study is a retrospective case-control study involving 95 women of reproductive age. It employs both univariate and multivariate binary logistic regression models to identify risk factors and symptoms associated with BV. The study also compares these clinical symptoms with laboratory tests (Amsel's test) and attempts to create a scoring system for BV diagnosis. Key Findings Good menstrual hygiene and condom use were identified as key behavioral practices reducing the risk of BV. Four clinical symptoms, like malodor (P = 0.007), lower abdominal pain (P = 0.015), abnormal vaginal discharge (P = 0.071), and painful intercourse (P = 0.08), were identified as notable predictors. Based on these four symptoms, the scoring system showed a sensitivity of 88.2%, a specificity of 67.25%, and an overall accuracy of 74.7%. An additional diagnosis of vulvovaginal candidiasis (VVC) revealed that the odds of malodor (P= 0.006) and burning sensation (P= 0.011) increased significantly during co-infection.

A review of latrine front-end characteristics associated with microbial infection risk; reveals a lack of pathogen density data

Unsafe sanitation accounts for an estimated 898,000 global deaths annually. The faecal pathogen transmission pathway is complex with several possible routes. Latrine front-end characteristics and usage behaviours are one key transmission pathway for microbial pathogens, however, there has not yet been a synthesis of the available research. This review aims to compare the microbial infection risks with latrine front-end components including any quantified microbial densities within the household latrines. This review was conducted with no restriction on the geographical location of the research. Of 118 studies reviewed, only ten (8%) have quantified the microbial density inside the household latrines compared to 109 (92%) measuring the infection risks. The reported risks were most frequent for specific bacterial (n = 34), and helminths infections (n = 32) compared to diarrhoea (n = 23), combined (n = 15), protozoan (n = 4), and viral (n = 4) infections. The infections risk decreased for using latrines lying at a higher position on the sanitation ladder (for example flush latrines) compared to those lying lower (for example pit latrines). The trend was similar for using floor materials that were easier to clean and less favourable for pathogen survival inside the latrines (for example, concrete as opposed to earth). Faecal coliforms were reported highest on the surface of the squat pan (743 CFU/cm2) of pour-flush latrines and helminths on earth floors of pit latrines (1.5 eggs and larvae per gram of soil). Irrespective of latrine type and its position on the sanitation ladder, a dirty latrine, evidenced by a visible lack of cleanliness, significantly increased the risk for all infections. This study recommends that effective microbial infection risk reduction in latrines can be gained efficiently by ensuring washable surfaces and consistent cleaning practices. Future studies should include more rigorous measurements of microbial densities in various latrine types incorporating the different front-end components and usage behaviours.

Development and validation of a predictive model for the risk of developing trichomonas vaginitis in women

Trichomonas vaginitis (TV) is the most common non-viral sexually transmitted infection (STI) worldwide. The high prevalence of TV combined with mild or asymptomatic early symptoms leads to clinical vulnerability from delayed diagnosis. Latent infection can increase the incidence of pelvic infections, infertility, and adverse pregnancy complications. Data from 898 women who underwent vaginal flora testing from June 2014 to December 2014 were used to create a nomogram to assess the risk of TV in women in order to guide TV prevention and clinical intervention. The prediction model was evaluated in terms of identification, calibration, and clinical utility using the C-index, calibration plots, decision curve analysis, and internal validation. Predictors in the TV nomogram included age, occupation, yearly income, tea drinking, bathing frequency, menopause, spontaneous abortion, use of contraceptives, history of gynecological surgery, and HPV infection. The C-index of the TV risk prediction model was 0.732 (95% confidence interval: 0.695-0.768). It showed good discriminatory and predictive power. Decision curve analysis indicated that the nomogram had a good net benefit when the threshold probability of TV in women was 2-80%. The established TV prediction model easily, accurately, and quickly predicts the risk of TV onset.
