Spatial heterogeneity in the exclusive use of hygienic materials during menstruation among women in urban India.

Background: Menstrual hygiene is essential for women to live with dignity. However, a large proportion of Indian women still suffer from unhygienic menstrual practices leading to reproductive tract infections. To understand the socioeconomic and bio-demographic determinants of menstrual hygiene practices, various national or local level studies have been conducted in India and around the world, however, no previous study has tried to understand the spatial heterogeneity across Indian districts in the use of hygienic materials among young urban women. Methods: This study used data from 54,561 urban women aged 15-24 from the National Family Health Survey-5. Global Moran's I was applied to assess the degree of spatial autocorrelation and cluster and outlier analyses to locate hot-spots and clod-spots in the exclusive use of hygienic materials across the districts. Ordinary least square, spatial lag, and error models were used to identify determinants of exclusive use of hygienic materials. Results: Approximately 66.8% of urban women exclusively use of hygienic materials which varied across districts. Global Moran's I of 0.46 indicated positive spatial autocorrelation in the outcome. Cluster and outlier analysis revealed cold-spots in central Indian districts and hotspots in south Indian districts. Results of spatial error model identified women's years of schooling, marital status, social group, and household wealth were major determinants of the exclusive use of hygienic materials among urban women across Indian districts. Conclusion: Substantial spatial heterogeneity in the outcome among urban women in India suggests the need to design targeted and context-specific behavioural interventions and programs for women in urban India.
