The burden of soil-transmitted helminths infections among pregnant women in Maharashtra and Rajasthan states of India.

Context: Soil-transmitted helminths (STH) infections are among the most common and widespread infections in developing countries where sanitation facilities are inadequate. Aims: This study aimed to estimate the prevalence of STH infections in prenatal mothers in two states in India. Settings and Design: A cross-sectional survey was conducted in Maharashtra and Rajasthan state of India. We randomly selected one municipal corporation and one rural block from a selected district in each state. Methods and Material: Out of 2400 contacted, 2206 pregnant women gave stool samples for microscopy for parasitological study. The response rate was 89.91%. Stool specimens were transported to an accredited lab and examined microscopically within 24 hrs. Results: Prevalence of STH was 8.34 (95%CI 7.22-9.57). The prevalence in rural and urban areas was 10.01% (95%CI 8.51-11.74) and 5.76% (95%CI 4.39-7.52), respectively. Ascaris lumbricoides (34.7%) were the most common, followed by Entamoeba histolytica (30.43%), and 20.1% were mixed infections. Higher age, walking barefoot, weight gain during pregnancy were significantly associated with STH (p < 0.05). The mean hemoglobin value in women with STH was significantly less (8.75 gm%; SD 4.04) compared to those without STH (10.23 gm%; SD 1.23) (p < 0.05), and average weight gain during pregnancy was significantly less among women with STH (3.80 kg; 4.11) compared to women without STH (8.45 kg; 2.83); (p = 0.000). Conclusion: The study provides valuable insights into the burden and intensity of STH in pregnant women that may support the policy recommendation for deworming during pregnancy.
