Disclosure experience and associated factors among HIV positive men and women clinical service users in southwest Ethiopia

BackgroundDisclosing HIV test results to ones sexual partner allows the partner to engage in preventive behaviors as well as the access of necessary support for coping with serostatus or illness. It may motivate partners to seek testing or change behavior, and ultimately decrease the transmission of HIV. The present study was undertaken to determine the rate, outcomes and factors associated with HIV positive status disclosure in Southwest Ethiopia among HIV positive service users.MethodsA cross-sectional study was carried out from January 15, 2007 to March 15, 2007 in Jimma University Specialized Hospital. Data were collected using a pre-tested interviewer-administered structured questionnaire.ResultsA total of 705 people (353 women and 352 men), participated in the study of which 71.6% were taking ART. The vast majority (94.5%) disclosed their result to at least one person and 90.8% disclosed to their current main partner. However, 14.2% of disclosure was delayed and 20.6% did not know their partners HIV status. Among those who did not disclose, 54% stated their reason as fear of negative reaction from their partner. Among those disclosures however, only 5% reported any negative reaction from the partner. Most (80.3%) reported that their partners reacted supportively to disclosure of HIV status. Disclosure of HIV results to a sexual partner was associated with knowing the partners HIV status, advanced disease stage, low negative self-image, residing in the same house with partner, and discussion about HIV testing prior to seeking services.ConclusionAlthough the majority of participants disclosed their test results, lack of disclosure by a minority resulted in a limited ability to engage in preventive behaviors and to access support. In addition, a considerable proportion of the participants did not know their partners HIV status. Programmatic and counseling efforts should focus on mutual disclosure of HIV test results, by encouraging individuals to ask their partners HIV status in addition to disclosing their own.

Factors associated with HIV/AIDS diagnostic disclosure to HIV infected children receiving HAART: a multi-center study in Addis Ababa Ethiopia.

Background Diagnostic disclosure of HIV/AIDS to a child is becoming an increasingly common issue in clinical practice. Nevertheless, some parents and health care professionals are reluctant to inform children about their HIV infection status. The objective of this study was to identify the proportion of children who have knowledge of their serostatus and factors associated with disclosure in HIV-infected children receiving HAART in Addis Ababa, Ethiopia. Methods A cross-sectional study was conducted in five hospitals in Addis Ababa from February 18, 2008–April 28, 2008. The study populations were parents/caretakers and children living with HIV/AIDS who were receiving Highly Active Antiretroviral Therapy (HAART) in selected hospitals in Addis Ababa. Univariate and multivariate logistic regression analysis were carried out using SPSS 12.0.1 statistical software. Results A total of 390 children/caretaker pairs were included in the study. Two hundred forty three children (62.3%) were between 6–9 years of age. HIV/AIDS status was known by 68 (17.4%) children, 93 (29%) caretakers reported knowing the childs serostatus two years prior to our survey, 180 (46.2%) respondents said that the child should be told about his/her HIV/AIDS status when he/she is older than 14 years of age. Children less than 9 years of age and those living with educated caregivers are less likely to know their results than their counterparts. Children referred from hospitals in-patient ward before attending the HIV clinic and private clinic were more likely to know their results than those from community clinic. Conclusion The proportion of disclosure of HIV/AIDS diagnosis to HIV-infected children is low. Strengthening referral linkage and health education tailored to educated caregivers are recommended to increase the rate of disclosure.

Adherence to highly active antiretroviral therapy and its correlates among HIV infected pediatric patients in Ethiopia

BackgroundThe introduction of combination antiretroviral therapy (ART) has resulted in striking reductions in HIV-related mortality. Despite increased availability of ART, children remain a neglected population. This may be due to concerns that failure to adhere appears to be related to continued viral replication, treatment failure and the emergence of drug-resistant strains of HIV. This study determines the rates and factors associated with adherence to Antiretroviral (ARV) Drug therapy in HIV-infected children who were receiving Highly Active Antiretroviral Therapy (HAART) in Addis Ababa, Ethiopia in 2008.MethodsA cross-sectional study was conducted in five hospitals in Addis Ababa from February 18 – April 28, 2008. The study population entailed parents/caretaker and index children who were following ART in the health facilities. A structured questionnaire was used for data collection.ResultsA total of 390 children respondents were included in the study with a response rate of 91%. The majority, equaling 205 (52.6%) of the children, were greater than 9 years of age. Fifty five percent of the children were girls. A total of 339 children (86.9%) as reported by caregivers were adherent to antiretroviral drugs for the past 7 days before the interview. Numerous variables were found to be significantly associated with adherence: children whose parents did not pay a fee for treatment [OR = 0.39 (95%CI: 0.16, 0.92)], children who had ever received any nutritional support from the clinic [OR = 0.34 (95%CI: 0.14, 0.79)] were less likely to adhere. Whereas children who took co-trimoxazole medication/syrup besides ARVs [OR = 3.65 (95%CI: 1.24, 10.74)], children who did not know their sero-status [OR = 2.53 (95%CI: 1.24, 5.19)] and children who were not aware of their caregivers health problem [OR = 2.45 (95%CI: 1.25, 4.81)] were more likely to adhere than their counterparts.ConclusionAdherence to HAART in children in Addis Ababa was higher than other similar setups. However, there are still significant numbers of children who are non-adherent to HAART.

Barriers and facilitators to antiretroviral medication adherence among HIV-infected paediatric patients in Ethiopia: a qualitative study.

Medication adherence is a complex behaviour with multiple determinants. Understanding the barriers and facilitators of adherence is invaluable for programme improvement, which assists the foundation of adherence intervention strategies. A qualitative study was conducted in six selected hospitals of Addis Ababa in 2008, to explore barriers and facilitators to antiretroviral medication adherence among HIV-infected paediatric patients. Twelve caregivers of adherent and non-adherent children and 14 key informants in five hospitals were included in the study. The findings revealed that over-dosage (heavy pill burden), fear of stigma and discrimination, cost and access to transportation, lack of understanding of the benefit of taking the medication, economic problems in the household, and lack of nutritional support were the barriers to adherence to HAART. The presence of mobile/wall alarm, the presence of follow-up counselling, improved health of the child, ART clinic setups, and disclosure of HIV serostatus were among the facilitators. This study indicated that paediatric adherence to antiretroviral therapy faces a huge challenge. It suggests the provision of income-generating schemes to caregivers for assisting HIV-infected children. Health care providers should address proper usage of medication reminders.

Effects of Helicobacter pylori, geohelminth infection and selected commensal bacteria on the risk of allergic disease and sensitization in 3-year-old Ethiopian children

Background Epidemiological studies have suggested that gastro‐intestinal infections including Helicobacter pylori, intestinal microflora (commensal bacteria) and geohelminths may influence the risk of asthma and allergy but data from early life are lacking.

Objective  To determine the prevalence of and factors associated with defaulting from antiretroviral treatment (ART) in Jimma, Ethiopia.

The role of acetaminophen and geohelminth infection on the incidence of wheeze and eczema: a longitudinal birth-cohort study

RATIONALE Acetaminophen has been hypothesized to increase the risk of asthma and allergic disease, and geohelminth infection to reduce the risk, but evidence from longitudinal cohort studies is lacking. OBJECTIVES To investigate the independent effects of these exposures on the incidence of wheeze and eczema in a birth cohort. METHODS In 2005-2006 a population-based cohort of 1,065 pregnant women from Butajira, Ethiopia, was established, to whom 1,006 live singleton babies were born. At ages 1 and 3, questionnaire data were collected on wheeze, eczema, childs use of acetaminophen, and various potential confounders, along with a stool sample for geohelminth analysis. Those without wheeze (n = 756) or eczema (n = 780) at age 1 were analyzed to determine the independent effects of geohelminth infection and acetaminophen use in the first year of life on the incidence of wheeze and eczema by age 3. MEASUREMENTS AND MAIN RESULTS Wheeze and eczema incidence between the ages of 1 and 3 were reported in 7.7% (58 of 756) and 7.3% (57 of 780) of children, respectively. Acetaminophen use was significantly associated with a dose-dependent increased risk of incident wheeze (adjusted odds ratio = 1.88 and 95% confidence interval 1.03-3.44 for one to three tablets and 7.25 and 2.02-25.95 for ≥ 4 tablets in the past month at age 1 vs. never), but not eczema. Geohelminth infection was insufficiently prevalent (<4%) to compute estimates of effect. CONCLUSIONS These findings suggest frequent acetaminophen use early in life increases the risk of new-onset wheeze, whereas the role of geohelminth infection on allergic disease incidence remains to be seen as the cohort matures.

Prevalence and risk factors for soil-transmitted helminth infection in mothers and their infants in Butajira, Ethiopia: a population based study.

BackgroundSoil-transmitted helminths (STHs) are widespread in underdeveloped countries. In Ethiopia, the prevalence and distribution of helminth infection varies by place and with age. We therefore investigated the prevalence of and risk factors for STH infection in mothers and their one year-old children living in Butajira town and surrounding rural areas in southern Ethiopia.MethodsIn 2005-2006, 1065 pregnant women were recruited in their third trimester of pregnancy. In 2006-2007, when children reached their first birthdays, data on the infants and their mothers were collected, including stool samples for qualitative STH analysis. Questionnaire data on various demographic, housing and lifestyle variables were available. Logistic regression analysis was employed to determine the independent risk factors for STH infection in the mothers and children.Results908 mothers and 905 infants provided complete data for analysis. Prevalence of any STH infection was 43.5% (95% confidence interval (CI) 40.2-46.8%) in mothers and 4.9% (95%CI 3.6-6.5%) in children. In the fully adjusted regression model, infrequent use of soap by the mother was associated with increased risk (odds ratio (OR) 1.40, 95% CI 1.04-1.88, and 1.66, 95% CI 0.92-2.99, for use at least once a week and less frequent than once a week respectively, relative to daily use; p for trend = 0.018), and urban place of residence (OR 0.45, 95% CI 0.28-0.73, p = 0.001) was associated with reduced risk of maternal STH infection. The only factor associated with STH infection in infants was household source of water, with the greatest risk in those using piped water inside the compound (OR 0.09, 95% CI 0.02-0.38 for river water, 0.20, 95% CI 0.56-0.69 for either well or stream water and 0.21, 95% CI 0.09-0.51 for piped water outside compared with piped water inside the compound, overall p = 0.002)ConclusionIn this rural Ethiopian community with a relatively high prevalence of STH infection, we found a reduced risk of infection in relation to maternal hygiene and urban living. Daily use of soap and a safe supply of water are likely to reduce the risk of STH infection.

Gender differences regarding barriers and motivators of HIV status disclosure among HIV-positive service users

There are inconsistent findings about the relation between gender and HIV status disclosure. We conducted a facility-based cross-sectional study, using qualitative and quantitative data collection methods, to explore gender differences in HIV-positive status disclosure among service users in south-west Ethiopia. Among 705 participants, an equal number of men and women (94.6% men v. 94.3%, women) indicated that they had disclosed their result to someone, and the majority (90.9% men v. 90.7% women) to their current main partner. ‘It is customary to tell my partner everything’ was the most frequently cited reason for disclosing (62.5% men v. 68.5% women). Reasons for non-disclosure varied by gender: men were concerned about their partners worry and exposure of their own unfaithfulness. Women feared physical violence, and social and economic pressure in raising their children. Factors that influenced disclosure also indicated gender variation. For men, disclosure of HIV results to a sexual partner was positively associated with knowing the partners HIV status and discussion about HIV testing prior to seeking services, while for women it was associated with knowing the partners HIV status, advanced disease stage, having no more than primary education, being married, and perceiving the current relationship as long-lasting. There was no significant difference in the proportion of HIV status disclosure among men and women. However, the contextual barriers and motivators of disclosure varied by gender. Therefore it is important that clinicians, counsellors, and health educators underscore the importance of gender-specific interventions in efforts to dispel barriers to HIV status disclosure.

Exposure to Helicobacter pylori infection in early childhood and the risk of allergic disease and atopic sensitization: a longitudinal birth cohort study

An inverse relation between Helicobacter pylori infection and allergic disease has been reported by a range of independent epidemiological studies, but evidence from longitudinal studies is scarce.
