Insights
Intestinal parasites (IPs) affect 21.8% of children in Nahavand, Iran. Age, gender, animal contact, and season are key risk factors for IPs, which are linked to diarrhea and vomiting.
Area of Science:
- Public Health
- Infectious Diseases
- Pediatrics
Background:
- Intestinal parasites (IPs) represent a significant global health challenge.
- Children are particularly vulnerable to the adverse health effects of IPs.
Purpose of the Study:
- To determine the prevalence of intestinal parasites among children aged 12 years and younger in Nahavand County, Iran.
- To identify risk factors associated with intestinal parasite infections in this pediatric population.
Main Methods:
- A cross-sectional study was conducted over six months (April-September 2014).
- Fecal samples from 500 children with gastrointestinal disorders were analyzed using various microscopy techniques.
- Data were statistically analyzed using Chi-square, Fisher's exact test, and logistic regression.
Main Results:
- The overall prevalence of intestinal parasite infections was 21.8% (109/500).
- Blastocystis sp. was the most common parasite (16.2%), followed by Cryptosporidium spp. (2.6%).
- Infections were significantly associated with age, gender, contact with domestic animals/soil, and season. IPs correlated significantly with diarrhea and nausea/vomiting.
Conclusions:
- Blastocystis sp. is the predominant intestinal parasite in children in Nahavand County; helminth infections have decreased.
- Age, gender, season, and contact with domestic animals or contaminated soil are significant predictors of IPs.
- IP infections in children with gastrointestinal disorders are strongly linked to symptoms like diarrhea and vomiting.
Aim:
Prevalence and risk factors associated with intestinal parasites among children ≤ 12 years old in Nahavand county western Iran, was the objective of this search.
Background:
Intestinal parasites (IPs) are important health problems among most societies.
Methods:
This cross sectional study was carried out during 6 months from April to September 2014 in Nahavand County western Iran. Fecal samples were collected from 500 children suffering from gastrointestinal disorders (GIDs) and examined by macroscopy and microscopic (using saline and iodine wet mount, formalin-ether sedimentation, Trichrome and modified Ziehl Neelsen staining) methods. Finally, data was analyzed using Chi-square (Chi2) test and Fisher's exact test as well as logistic regression.
Results:
21.8% (109/500) of the samples were infected by one or more IPs. The most common parasites were Blastocystis sp. (16.2%), followed by Cryptosporidium spp. (2.6%), Giardia lamblia (1.6%), and Entamoeba coli (1.6%). Prevalence of intestinal parasite infections were significantly associated with age (OR= 2.280; CI 95% = 1.375-3.830; P<0.002), gender (OR= 0551; CI 95% = 0.348-0.875; P<0.011), contact with domestic animal or soil (OR= 0.492; CI 95% = 0.282-0.860; P<0.013) and seasons (OR= 2.012; CI 95% = 1.254-3.227; P<0.004). There was a significant correlation between IPs with diarrhea (OR= 3.027; CI 95% = 1.712-5.345; P<0.001) and nausea or vomiting (OR= 3.261; CI 95% = 1.281-8.175; P<0.013).
Conclusion:
Blastocystis sp. was the most prevalent parasites among children in Nahavand County and Helminthes infection have been dramatically decreased. Our finding shown that gender, age, season and contact with domestic animals or soil polluted are main predictive factors for intestinal parasite infections among children in this region. Moreover, IPs infection among children with gastrointestinal disorders were significantly associated with diarrhea and vomiting or nausea signs.
