RESUMO

Purpose The purpose of this article was to assess the pattern of supplement use and associated factors among pregnant women in Ethiopia. Methods A facility-based cross-sectional study was conducted. A total of 339 pregnant women were included in the study, 63 (18.3%) and 23 (6.8%) of whom used at least 1 supplement during pregnancy and 2 to 4 weeks prior to pregnancy, respectively. Only 3 women were prescribed folic acid during pregnancy. The pregnant women were interviewed to collect supplements use and pregnancy-related information through a pretested semistructured questionnaire. Subsequent charts of prescribed supplements were reviewed using a pretested data collection format. Results The majority (76.4%) of the women claimed no awareness about the benefits of early supplementation. Supplement use was about 8 times higher among women with > 3 children (adjusted odds ratio, 7.85; 95% confidence interval, 1.69-36.28; P = .008) than among nulliparous women, and about 6 times higher among women in their second trimester (adjusted odds ratio, 6.26; 95% confidence interval, 1.91-20.55; P = .03) of pregnancy compared to those women in their first trimester. Conclusion Overall supplement use, particularly folic acid intake, was found to be negligible during the prenatal as well as antenatal periods. The majority of the women in the study lacked awareness about the benefits of supplementation and potential risks associated with the absence of folic acid during pregnancy. Information by the media and health care personnel given to childbearing women about the need to take folic acid to prevent neural tube defects seems to improve the intake of folic acid during the protective period.

RESUMO

BACKGROUND: Tuberculosis is one of the most frequent causes of death among adults despite being nearly 100% curable in the developing world. The lifetime risk of tuberculosis in immune competent persons is 5% to 10%, but in HIV positive individuals, there is a 5% to 15% annual risk of developing active tuberculosis disease and there appears to be little research addressing HIV and tuberculosis co-infection. OBJECTIVE: To synthesise the best available evidence on risk factors for developing tuberculosis after highly active antiretroviral treatment initiation among HIV patients INCLUSION CRITERIA: HIV patients who had initiated highly active antiretroviral treatment and were above 15 years of age.Risk factors for developing active tuberculosis among HIV patients after initiation of highly active antiretroviral treatment.Analytical epidemiological study designs were included in the review.The studies considered in this review included socio-demographic and clinical variables as risk factors for developing tuberculosis after HAART initiation such as, but not limited to: baseline CD4 count, HAART type, WHO clinical stage of HIV, previous history of TB and gender. SEARCH STRATEGY: English language articles published between January 1997 and December 2011 were searched using a comprehensive search strategy. ASSESSMENT OF METHODOLOGICAL QUALITY: Conducted, using the Joanna Briggs Institute critical appraisal tools. DATA EXTRACTION: Carried out, using the Joanna Briggs Institute data extraction tool. DATA SYNTHESIS: Meta- analysis was conducted using random effects model with Rev Man 5 software. RESULTS: Five cohort studies were included in the review. The risk of developing active tuberculosis after initiating highly active antiretroviral treatment was found to be 2.14 times higher in subjects with a baseline CD4+ cell count ≥ 200 than their counterparts with a 95% CI from 1.52 to 3.02 and this effect was statistically significant, p<0.0001. The overall effect of gender on development of post highly active antiretroviral treatment tuberculosis was found to be not significant, p=0.64. The meta analysis for prior TB history as a risk factor favoured those who didn't have prior tuberculosis history to have 1.24 times higher risk than their counter parts even if it is not found to be statistically significant, p=0.56. There was no difference identified in the risk of developing post highly active antiretroviral treatment tuberculosis among patients taking protease inhibitor based treatment regimens and those taking non nucleoside reverse transcriptase inhibitor based treatment regimen. The last variable considered as a risk factor for post highly active antiretroviral treatment tuberculosis was the WHO's clinical stages for HIV and the risk was found to be 1.77 times higher among those who were at stage 1 or 2 during enrolment than their counterparts but this risk is not statistically significant, p=0.44. CONCLUSIONS: Having no prior tuberculosis history, female gender and WHO clinical stage of HIV at enrolment were found to be a risk but their relation with post highly active antiretroviral treatment tuberculosis was not statistically significant. The meta-analysis also did not identify any difference among the groups taking protease inhibiter based and non nucleoside reverse transcriptase inhibiters (NNRTI) based treatments in relation to post highly active antiretroviral treatment tuberculosis. But, the analysis revealed that there exists a statistically significant risk for developing post highly active antiretroviral treatment tuberculosis among individuals having a baseline CD4+ cell count ≥ 200 being found to be at higher risk.Unlike other HIV-associated opportunistic infections, tuberculosis may occur at relatively high CD4+ cell counts. Patients with no prior tuberculosis history and at WHO clinical stage 1 or 2 of HIV may also be at risk of developing post-HAART TB and need to be investigated thoroughly.Further longitudinal studies covering all other possible risk factors such as genetic and behavioral factors need to be carried out to produce comprehensive data.
