Association between infection with Helicobacter pylori and platelet indices among school-aged children in central Ethiopia: a cross-sectional study.

ABSTRACT: OBJECTIVE:Previous clinical studies in adults from developed countries have implicated Helicobacter pylori infections in the development of thrombocytopenia. However, studies in children, particularly those from low-income countries, are unusually scarce. We examined the association between H. pylori infection and platelet indices in young Ethiopian school children. DESIGN:Cross-sectional study SETTING: This study was conducted in five elementary schools located in central Ethiopia. PARTICIPANTS:Blood and stool samples were collected from 971 children across five elementary schools in Ethiopia. H. pylori infection was diagnosed using stool antigen and serum antibody tests, and haematological parameters were measured using an automated haematological analyser. An interviewer-led questionnaire administered to mothers provided information on demographic and lifestyle variables. The independent effects of H. pylori infection on platelet indices were determined using multivariate linear and logistic regressions. STUDY OUTCOMES:H. pylori-infected children had a lower average platelet count and mean platelet volume than uninfected after adjusting the potential confounders (adjusted mean difference: -20.80×109/L; 95% CI -33.51 to -8.09×109, p=0.001 and adjusted mean difference: -0.236 fL; 95% CI -0.408 to -0.065, p=0.007, respectively). Additionally, H. pylori-infected children had lower red blood cell counts (adjusted mean difference: -0.118×1012/L; 95% CI -0.200 to -0.036, p=0.005) compared with non-infected. CONCLUSION:Our study from a developing country provides further support for an association between H. pylori infections and reduced platelet indices in young Ethiopian school children, after controlling for potential confounders. Further research is needed, particularly longitudinal studies, to establish causality.

Project description:BackgroundHuman immunodeficiency virus (HIV) positive status disclosure is an essential component of Pediatric care and long term disease management. Children have a right to know their HIV diagnosis result. However, Pediatric HIV disclosure is complex and varies in different communities. This study aimed to assess the prevalence of HIV-positive status disclosure to infected children and associated factors among caregivers of infected children.MethodologyA facility based mixed methods research design study was conducted in Bale Zone of South East Ethiopia. Randomly selected caregivers of HIV-positive children were interviewed using structured questionnaires for quantitative study and 17 in-depth interviews of health care workers and caregivers were conducted for qualitative data. Content analysis was done for qualitative data and logistic regression analysis was used to see the association between different variables and HIV-positive disclosure status. Odds ratio with 95% CI was computed to determine the presence and strength of the associated factors.ResultsA total of 200 caregivers of school aged (6-14 years) children participated in the study. Only 57 (28.5%) of the care givers disclosed HIV-positive status to the child for whom they were caring. The main reason for disclosure delay was due to fear of negative consequences, perception on maturity of the child, and fear of social rejection and stigma. Having social support [AOR = 2.7, 95% CI: (1.1-6.4)], caring for a child between 10 and 14 years with HIV [AOR = 6.5, 95% CI: (2.1-20.2)], a child diagnosed with HIV at age > 5 years [AOR = 2.8, 95% CI: (1.1-7.1)], and children on antiretroviral therapy (ART) with follow-up for > 5 years [AOR = 4.7, 95% CI: (1.8-11.2)] had significant association with HIV- positive status disclosure to infected children.ConclusionThe frequency of HIV infection disclosure to infected children was very low in our cohort. Having social support, having an older child with HIV, a long period of ART follow-up and HIV diagnosis after age of five years were positively associated with HIV-positive status disclosure to infected children. Giving age appropriate counselling to children, social support to the caregivers and working on related factors are very important to improve the observed low disclosure status.

Project description:BackgroundSoil-transmitted helminths (STH) remain a major public health problem, particularly in tropical and sub-tropical regions of the world. Though infections are prevalent among all age groups, the world health organization (WHO) considers Pre-school age children (PSAC), school-aged children, and pregnant women as segments of population at high risk of STH morbidities.ObjectiveThis study aimed at determining the prevalence and infection intensity of STH and associated factors among PSAC in Butajira Town, south-central Ethiopia.MethodsA community-based cross-sectional study was conducted from May to June, 2014 in Butajira Town. The PSAC were selected by systematic sampling technique and invited to participate in the present study. McMaster technique was employed for parasitological analysis of stool samples. Pearson's Chi-square and Fisher's exact tests were performed where appropriate to identify any association between STH infection and independent factors. Multivariate logistic regression model was fitted to identify independent predictors of STH among the PSAC. P-value less than 0.05 was considered statistically significant.ResultsA total of 377 (with 96% compliance rate) PSAC were able to provide complete data (socio-demographic information and stool sample). The study showed that 23.3% (88/377) PSAC were infected with one or more species of STH. Ascaris lumbricoides was the most prevalent STH (14.9%) followed by Trichuris trichiura (6.4%). The overall infection intensity, expressed as geometric mean for A. lumbricoides, T. trichiura, and hookworms were 229, 178, and 154 eggs per gram of stool, respectively. The multivariate logistic regression model estimated that being in the age group of 36-47 months (AOR: 2.5, 95% CI: 1.2-5.3, P = 0.016), untrimmed finger nail (AOR: 3.2, 95% CI: 1.8-5.5, P < 0.001), and not washing hands before a meal (AOR: 3.0, 95% CI: 1.7-5.4, P < 0.001) were independent predictors of STH infections among the children.ConclusionThe present study showed that STH was a public health problem among PSAC in the study area necessitating annual deworming to control morbidities associated with STH. Besides, the existing health education program should also be strengthened to prevent re-infection.

Project description:IntroductionLittle information is available on malnutrition-related factors among school-aged children ?5 years in Ethiopia. This study describes the prevalence of stunting and thinness and their related factors in Libo Kemkem and Fogera, Amhara Regional State and assesses differences between urban and rural areas.MethodsIn this cross-sectional study, anthropometrics and individual and household characteristics data were collected from 886 children. Height-for-age z-score for stunting and body-mass-index-for-age z-score for thinness were computed. Dietary data were collected through a 24-hour recall. Bivariate and backward stepwise multivariable statistical methods were employed to assess malnutrition-associated factors in rural and urban communities.ResultsThe prevalence of stunting among school-aged children was 42.7% in rural areas and 29.2% in urban areas, while the corresponding figures for thinness were 21.6% and 20.8%. Age differences were significant in both strata. In the rural setting, fever in the previous 2 weeks (OR: 1.62; 95% CI: 1.23-2.32), consumption of food from animal sources (OR: 0.51; 95% CI: 0.29-0.91) and consumption of the family's own cattle products (OR: 0.50; 95% CI: 0.27-0.93), among others factors were significantly associated with stunting, while in the urban setting, only age (OR: 4.62; 95% CI: 2.09-10.21) and years of schooling of the person in charge of food preparation were significant (OR: 0.88; 95% CI: 0.79-0.97). Thinness was statistically associated with number of children living in the house (OR: 1.28; 95% CI: 1.03-1.60) and family rice cultivation (OR: 0.64; 95% CI: 0.41-0.99) in the rural setting, and with consumption of food from animal sources (OR: 0.26; 95% CI: 0.10-0.67) and literacy of head of household (OR: 0.24; 95% CI: 0.09-0.65) in the urban setting.ConclusionThe prevalence of stunting was significantly higher in rural areas, whereas no significant differences were observed for thinness. Various factors were associated with one or both types of malnutrition, and varied by type of setting. To effectively tackle malnutrition, nutritional programs should be oriented to local needs.

Project description:IntroductionThe present study describes the distribution of selected micronutrients and anaemia among school-aged children living in Libo Kemkem and Fogera (Amhara State, Ethiopia), assessing differences by socio-demographic characteristics, health status and dietary habits.MethodsA cross-sectional survey was carried out during May-December 2009. Socio-demographic characteristics, health status and dietary habits were collected. Biomarkers were determined for 764 children. Bivariate and multivariable statistical methods were employed to assess micronutrient deficiencies (MD), anaemia, and their association with different factors.ResultsMore than two thirds of the school-aged children (79.5%) had at least one MD and 40.5% had two or more coexisting micronutrient deficiencies. The most prevalent deficiencies were of zinc (12.5%), folate (13.9%), vit A (29.3%) and vit D (49%). Anaemia occurred in 30.9% of the children. Children living in rural areas were more likely to have vit D insufficiency [OR: 5.9 (3.7-9.5)] but less likely to have folate deficiency [OR: 0.2 (0.1-0.4)] and anaemia [OR: 0.58 (0.35-0.97)]. Splenomegaly was positively associated with folate deficiency and anaemia [OR: 2.77 (1.19-6.48) and 4.91 (2.47-9.75)]. Meat and fish consumption were inversely correlated with zinc and ferritin deficiencies [OR: 0.2 (0.1-0.8) and 0.2 (0.1-0.9)], while oil consumption showed a negative association with anaemia and deficiencies of folate and vitamin A [0.58 (0.3-0.9), OR: 0.5 (0.3-0.9) and 0.6 (0.4-0.9)]. Serum ferritin levels were inversely correlated to the presence of anaemia (p<0.005).ConclusionThere is a high prevalence of vitamin A deficiency and vitamin D insufficiency and a moderate prevalence of zinc and folate deficiencies in school-aged children in this area. The inverse association of anaemia and serum ferritin levels may be due to the presence of infectious diseases in the area. To effectively tackle malnutrition, strategies should target not only isolated micronutrient supplementation but also diet diversification.
