Prevalence of intestinal parasitic infections and associated risk factors among students at Dona Berber primary school, Bahir Dar, Ethiopia

Prevalence of intestinal parasitic infections and associated factors among street children in Jimma town; south West Ethiopia in 2019: a cross sectional study

BACKGROUND

Street child is any child whose age is less than 18 years for whom the street has become his or her habitual abode and/or source of livelihood, is inadequately protected, supervised or directed by responsible adults. In Ethiopia the health problems of street children are given poor attention in research. This problem is pronounced when it comes to intestinal parasitic infections, making it difficult to design appropriate interventions targeting this segment of population. The aim of this study was to assess the prevalence of intestinal parasitic infections and associated factors among street children in Jimma town in the year 2019.

METHODS

Community based cross sectional study was employed. Complete enumeration was used to include 312 street children. Pretested questionnaire was used to collect the data. Data was entered to Epidata version 3.1 and exported to SPSS version 20. Stool samples were examined by wet mount and formalin ether concentration techniques. Bivariable and multivariable logistic regression was used to identify factors associated with intestinal parasitic infection. Significance of association was decided by using the 95% confidence interval of AOR and P-value of ≤0.05 in the multivariable model.

RESULT

A total of 312 children of the street were involved in the study making the response rate 96.2%. The prevalence of intestinal parasitic infection was 66.7%. Untrimmed finger nails AOR = 2.03;95%CI (1.02-4.06), eating street food AOR = 2.24;95% CI (1.04-5.02), practice of swimming in unprotected water bodies AOR = 2.5; 95% CI (1.24-5.04), not wearing shoes at the time of data collection AOR = 3.8;95% CI (1.8-8.2) and lacking knowledge of way of transmission of intestinal parasites AOR = 2.5; 95% CI (1.25-5.0) were significantly associated with parasitic infections.

CONCLUSIONS

The prevalence of intestinal parasitic infections among street children in the study area was high and require integrated interventions to avert the problem. Several factors were also found to be associated with intestinal parasitic infections. Measures has to be taken to curb the problem by including them in mass drug administration and targeted health education towards identified factors.

Prevalence of selected intestinal protozoan infections in marginalized rural communities in Palestine

Background

Intestinal parasitic infections are common in rural areas with poor infrastructure and low socioeconomic status. The aim of this study was to estimate the prevalence of selected parasitic infections in marginalized rural areas in the northern part of the Palestinian West Bank Region, using conventional and PCR-based methods, and also to assess risk predictors of infection.

Methods

A cross-sectional study was conducted on 104 individuals from three rural villages in the Jordan Valley. Stool samples were collected and examined by a battery of tests that included microscopy of wet fecal samples in normal saline with iodine, concentration by ethyl acetate sedimentation and also by zinc sulfate floatation, a conventional PCR and a real-time PCR (qPCR). Risk factors were assessed that included demographic, socioeconomic, and behavioral characteristics. Data on method performance was analyzed by kappa-statistic, Cochrane’s Q, and McNemar post hoc test. Mid-P exact test and odds ratio were used to discern association between outcome and risk predictors.

Results

The overall prevalence of intestinal parasitic infections was 48% (49/102). The predominant parasites were Giardia lamblia at 37% (37/102) and Hymenolepis nana at 9% (9/102). To concentrate cysts and eggs, sedimentation can be used as an alternative to floatation with a loss of 1% of positive cases. The methods employing PCRs proved crucial as it increased the detected infection rate of G. lamblia approximately three-fold from 13% by the conventional methods to 37% by the qPCR. Multiple infections were present in 13% (13/102) of the study group, which included double (10%) and triple (3%) infections. Regarding the genus Entamoeba, E. dispar and E. coli were detected at rates of 2 and 8%, respectively. While none of the individuals were infected with the pathogenic E. histolytica, E. nana (4%) was detected for the first time in the area. Age was a risk predictor for infection (OR = 2.61, CI 95% 1.05–6.45, P = 0.038).

Conclusions

The increased prevalence of intestinal parasitic infections in children in marginalized rural areas in Palestine is worrying. The addition of PCR-based methods is important for the diagnosis of such infections as, with cautious interpretation, it increases proficiency and overcomes underestimation and misdiagnosis of cases. Control measures including education on personal hygiene and environmental sanitation, should be introduced to reduce the prevalence of the intestinal parasites and, thus, the infections they cause in this and other areas.

Intestinal parasitic infections and determinant factors among school-age children in Ethiopia: a cross-sectional study

OBJECTIVE

This study aimed to determine the prevalence of intestinal parasitic infections and associated factors among school-age children in Sebeya primary school, northern Ethiopia, 2017.

RESULTS

The prevalence of intestinal parasites in school-age children was (29.9%). A total of six parasites were detected in this study. E. histolytica/dispar 19.43% (82/422) and G. lamblia 8.29% (35/422) were the predominant ones. Unclean fingernail (AOR = 1.72), defecating in the open field (AOR = 2.82), and being barefooted (AOR = 1.72) were the determinant factors for intestinal parasitic infections. Frequently washing hands reduced the chance of infections by 68%. Furthermore, children in grade 1-4 and 5-6 had higher odds developing the infections than those in grade 7-8 (AOR = 8.21 and AOR = 2.50, respectively).

Prevalence and risk factors of intestinal parasitic infestations among preschool children in Sekota town, Waghimra zone, Ethiopia

Background

Intestinal parasitic infestations triggered considerable gastrointestinal morbidity, malnutrition, and mortality worldwide. In particular, young children in developing countries affected most. Helminthiasis infestation accounts for 10–20% of prevalence on preschool children worldwide. Unfortunately, small children below 5 years are uniquely susceptible to intestinal parasitic infestations in poor communities. This is because of children’s behavior like playing with soil and putting hand -to- mouth habit. Thus, the aim of this study was to assess the prevalence and risk factors of intestinal parasitic infestations among preschool children in Sekota town, Ethiopia.

Methods

A community-based cross-sectional study was carried out on 378 preschool children in Sekota town from February 15 – March 10/2019. Stool specimens were collected and examined for intestinal parasites using wet mount and formal ether concentration technique. The risk factors of intestinal parasites were assessed using a pretested structured questionnaire. The data were entered and analyzed using Epi-data version 4.2.0.0 and SPSS-version 23 statistical software respectively. Both bivariable and multivariable analysis was carried out, and potential co-linearity was tested for closely similar variables. Variables with P value less than 0.05 in multivariable analysis was considered as statistically significant and reported with 95% CI and odds ratio.

Results

The prevalence of intestinal parasitic infestations in Sekota town on wet mount and formal ether concentration techniques was 83(21.9%), (95% CI, 17.7–26.3%) and 113(29.9%), (95% CI, 25.1–34.8%) respectively.

In multivariable analysis, not taking medication as periodical deworming (AOR, 95% CI), (2.5, 1.5–4.3), presence of animals in the living room (AOR, 95% CI) (3.1, 1.8–5.3), and being a government employee as an occupation (AOR, 95% CI), (3.4, 1.1–10.0) were increasing the odds of intestinal parasitic infestations.

Conclusions

The prevalence of intestinal parasitic infestations in Sekota town is high, which is a public health problem. The risk factors that contributed to intestinal parasitic infestations in this study were preventable and modifiable. Therefore, the concerned bodies need to emphasis on periodical deworming and keeping animals in separate room.

Soil-Transmitted Helminths And Other Intestinal Parasites Among Schoolchildren In Southern Ethiopia

Background

Intestinal parasitic infections are the neglected tropical diseases that have a devastating effect and leads to malnutrition, morbidity and mortality in schoolchildren. The aim of this study was to determine the presence of soil-transmitted and other intestinal parasites among schoolchildren in southern Ethiopia.

Methods

A cross-sectional study was conducted in Gara Riketa primary school children at Hawassa Tula Sub-City, Southern Ethiopia from March 1 to April 20, 2017. The parent of participating children was interviewed with a structured questionnaire to collect the sociodemographic and risk factors data. Well-trained laboratory technicians were involved in the stool examination through direct and concentration methods. The data were entered and analyzed using SPSS version 20. ORs at 95% CI were considered as a statistically significant association with a p-value < 0.05.

Results

Out of 384 schoolchildren enrolled for the study, 260 (67.7%) were infected with one or more intestinal parasites. The predominantly identified parasite was Ascaris lumbricoides 146 (38.0%) followed by hookworms 12 (3.1%). The study showed that intestinal parasitic infections have a statistically significant association with being in 4th grade, the mother´s educational status (grade 9-12), having cut nails and washing hands before eating.

Conclusion

The rates of soil-transmitted helminths and other intestinal parasitic infections were very high in Gara Riketa primary school children. Based on the statistical analysis, hygiene and nail clipping are important habits to prevent infection with intestinal parasites.

Intestinal parasitic infections and associated factors among mentally disabled and non-disabled primary school students, Bahir Dar, Amhara regional state, Ethiopia, 2018: a comparative cross-sectional study

Background

Intestinal parasitic infections are still common in low-income countries including Ethiopia, particularly in children due to low-quality drinking water, poor personal and environmental sanitation. Disabled individuals are excluded from most academic, economic, social and cultural opportunities, they are among the poorest and most marginalized of the whole world’s people.

The aim of this study was to assess the prevalence of intestinal parasitic infections and associated factors among mentally disabled and non-disabled students at primary schools in Bahir Dar city, Amhara regional state, Ethiopia, 2018.

Methods

A school-based Comparative cross-sectional study design was conducted from November 1–30, 2018. A total of 418 study participants, 104 mentally disabled and 314 non-disabled students were recruited through a simple random sampling technique. The collected data were coded, entered and cleaned with EpiData version 3.1 and analyzed using SPSS version 23. Multivariable logistic regression was conducted to identify factors associated with intestinal parasitic infections. The adjusted odds ratio with a 95% Confidence interval at a 5% level of significance was used to measure the strength of association.

Results

The mean age of study participants was 14.05 ± 3.66 and 11.96 ± 2.94 for mentally disabled students and non-disabled students. Prevalence of parasitic infection was 56.70% (n = 59) for mentally disabled students whereas 41.10%(n = 129) for non-disabled students. Unclean fingernails [AOR = 2.42; 1.40,4.17], health checkups [AOR = 1.87;1.16,3.02], hand washing with water only [AOR = 2.48; 1.49,4.12], cooking and sanitation source of water [AOR = 4.40;2.32,8.36], Grade [ (1–4)] [AOR = 2.27;1.41,3.67], sex [AOR = 1.64;1.03,2.63] and Family size> = 7 [AOR = 2.74;1.25,5.99] were variables which showed statistically significant association with intestinal parasitic infections.

Conclusion

The prevalence of intestinal parasitic infection was higher among mentally disabled students than non-disabled students. Unclean fingernails, health checkups, hand washing habits, source of water, family size, sex and Grade of students have had a statistically significant association with intestinal parasitic infections. Periodic medicinal treatment was needed twice a year for mentally disabled and once a year for non-disabled students.

Epidemiological Survey on Schistosomiasis and Intestinal Helminthiasis among Village Residents of the Rural River Basin Area in White Nile State, Sudan

There have been some reports on schistosomiasis of school children in Sudan’s Nile River basin area; however, information about the infection status of Schistosoma species and intestinal helminths among village residents of this area is very limited. Urine and stool samples were collected from the 1,138 residents of the Al Hidaib and Khour Ajwal villages of White Nile State, Sudan in 2014. The prevalence of overall schistosomiasis and intestinal helminthiasis was 36.3% and 7.7%, respectively. Egg positive rates were 35.6% for Schistosoma haematobium, 2.6% for S. mansoni, and 1.4% were mixed. The prevalence of schistosomiasis was significantly higher in men (45.6%) than in women (32.0%), in Khou Ajwal villagers (39.4%) than in Al Hidaib villagers (19.2%), and for age groups ≤15 years old (51.5%) than for age groups >15 years old (13.2%). The average number of eggs per 10 ml urine (EP10) of S. haematobium infections was 18.9, with 22.2 eggs in men vs 17.0 in women and 20.4 in Khou Ajwal villagers vs 8.1 in Al Hidaib villagers. In addition to S. mansoni eggs, 4 different species of intestinal helminths were found in the stool, including Hymenolepis nana (6.6%) and H. diminuta (1.0%). Collectively, urinary schistosomiasis is still prevalent among village residents in Sudan’s White Nile River basin and was especially high in men, children ≤15 years, and in the village without a clean water system. H. nana was the most frequently detected intestinal helminths in the 2 villages.

Prevalence of intestinal parasitic infections and associated risk factors among Jawi primary school children, Jawi town, north-west Ethiopia

BACKGROUND

Intestinal parasitic infections (IPIs) have been major public health problems in low income countries primarily affecting school children. Previous studies in Ethiopia have shown high burden of intestinal parasitic infections in most children. In order to gain a deeper insight into the magnitude of the problem more information is needed from different localities where similar studies have not been conducted. The aim of this study was to assess the prevalence of IPIs and associated risk factors among school children in Jawi Primary School, Jawi town, north -west Ethiopia.

METHODS

A cross-sectional study was conducted from April to June 2017 to assess the prevalence of IPIs and associated risk factors among Jawi Primary School children, Ethiopia. A total of 422 children were selected using age-stratified systematic random sampling technique. Stool samples were examined microscopically using direct wet-mount and formal-ether concentration techniques. A structured questionnaire was used to obtain information regarding the associated risk factors. Data were analyzed using SPSS version 20 and p value < 0.05 was taken as statistically significant.

RESULTS

Of 406 students examined for IPIs, 235 (57.88%) were positive for one or more intestinal parasites. Single, double and triple infections were 41.9, 6.2 and 1.2%, respectively. Overall infection rate was slightly higher in males (51.85%) than in females (45.30%) though the difference was not significant. Higher prevalence rate (about 51-53%) was recorded among 6 to 18 years old children. Prevalence of Giardia lamblia was the highest (19.95%), followed by hookworm (13.8%), Schistosoma mansoni (10.3%), Entamoeba histolytica/dispar (5.9%), Hymenolepsis nana (4.2%), Taenia species (3%) and Ascaris lumbricoides (0.73%), in that order. Among the risk factors assessed, age, hand washing habit before meals, open field defecation habit, consistency of wearing shoes, habit of eating raw and unwashed vegetables, and finger nail cleanliness and trimming habit were found to be the most important predictors associated with high risk of IPIs (p < 0.05).

CONCLUSION

High prevalence of IPIs among Jawi Primary school children demands improved health education on regular hand washing, latrine use, wearing shoes, cleaning finger nails, not crossing rivers with bare foot and avoiding eating raw vegetables.

Current status of intestinal parasitic infections and associated factors among primary school children in Birbir town, Southern Ethiopia

Background

Intestinal parasites still pose major public health problems in developing countries like Ethiopia. Local epidemiological data is indispensable in order to design and monitor prevention and control strategies. Therefore the present study aimed to assess the prevalence of intestinal parasitic infections and associated factors among students at Birbir town, Southern Ethiopia.

Methods

A school-based cross-sectional study was conducted from March to May 2018. Three hundred fifty-one students, who were selected by stratified followed by systematic random sampling, participated in the study. Socio-demographic information was collected using a structured questionnaire. Anthropometric measurements of height and weight were taken at the time of interview. Stool samples were collected and processed by direct wet mount and formol-ether concentration techniques for microscopic detection of intestinal parasites. Data was analyzed using SPSS version 20.

Results

Among 351 (180 male and 171 female) children participated, 135 (38.5%) and 216 (61.5%) were within the age groups of 5–9 and 10–14 respectively. Ninety five (27.1%; 95%CI: 22.2–31.9) of them were tested positive for intestinal parasites. Helminths and protozoa account 21.1 and 7.1% prevalences respectively. Seventy eight children were infected with a single parasite species while 17 were positive for double or triple infections. A. lumbricoides (31, 8.8%) was the most frequently detected parasite followed by T. trichiura (20, 5.7%) and hookworms (19, 5.4%). Age group of 10–14 years (AOR = 2.51; 95%CI: 1.41–4.45, p = 0.002) and absence of hand washing habit after toilet (AOR = 4.49; 95%CI: 2.00–10.1, p = 0.001) were significantly associated with intestinal parasitic infection.

Conclusions

The prevalence of intestinal parasitic infection among school age children is still unacceptably high. Age group of 10–14 year old and not having habit of hand washing after toilet were significantly associated with intestinal parasitic infection. The ongoing school based deworming should be strengthened and be integrated with school health programs.

Burden of intestinal helminths and associated factors three years after initiation of mass drug administration in Arbaminch Zuria district, Southern Ethiopia

BACKGROUND

Epidemiological information on the burden of various parasitic infections and associated factors in different localities is indispensable to develop appropriate control and prevention measures as well as to monitor and evaluate existing programs. Hence the aim of the present study was to assess the prevalence and associated factors of intestinal helminths among school age children in Arbaminch Zuria district, Southern Ethiopia.

METHODS

A community based cross-sectional study was conducted by recruiting 391 primary school age children. Participants were selected using simple random sampling technique. Pre-tested structured questionnaire was used to collect data about socio-demographic characteristics and perceived factors associated with intestinal parasitosis. Stool microscopic examination was done following standard protocol. Data were analyzed using Statistical Package for Social Science version 22.

RESULTS

Among 391 children participated, 181 (46.3%; 95% CI: 41.9-51.5) were infected with intestinal helminths. The magnitudes of single and double infections were 40.2% and 6.1% respectively. Seven helminths were detected among which Ascaris lumbricoides was with the highest frequency (56, 14.3%) followed by hookworms (55, 14.1%). Not washing fruits and vegetables before consumption (AOR = 2.16; 95%CI: 1.10-4.25, p = 0.026) and habit of swimming (AOR = 1.17; 95%CI: 1.03-1.95, p = 0.045) were significantly associated with helminthic infection.

CONCLUSION

High prevalence of intestinal helminthic infections among school age children demands integration of deworming with water, hygiene and sanitation as well as consistent health education.

The role of family size, employment and education of parents in the prevalence of intestinal parasitic infections in school children in Accra

INTRODUCTION

Intestinal parasitic infections (IPIs) in school children are a public health problem in most developing countries.

METHODS AND PRINCIPAL FINDINGS

A cross sectional survey was conducted from May to July 2016 with school children living in overcrowded urban slums in Accra, Ghana. A simple random sample of 300 children aged 2-9 years was collected. The study used structured pre-tested questionnaire and stool tests to obtain information on epidemiological, sanitation habits, employment and education status of parents and children. Data were analysed using appropriate descriptive, univariate and multivariable logistic tools of analyses. The mean age of participants was 6.9 years and 49% were males and 51.3% were females. Giardia lamblia was found in males (10.95%) and females (7.79%). Very low prevalences for Schistosoma mansoni, Ascaris lumbricoides, Taenia species, and Entamoeba coli were detected. Whilst children from mothers (62.2%) and fathers (55.6%) with no education were often infected, a few children from fathers (22.2%) and mothers (6.7%) with no jobs were infected. Most of the infected children's (93.7%) parents did not have any knowledge of IPIs. The educational and employment status of the mothers [p = 1.0 and p = 0.422] was not significant, however, the family size was a predisposing factor (p = 0.031) for parasitic infections.

CONCLUSIONS

Intestinal parasites were prevalent in children from overcrowded families and with no knowledge of IPIs. Educative programmes on IPIs, improving hygiene, and application of supportive programmes to elevate socioeconomic conditions may help reduce the burden of intestinal parasite carriage in children.
