Anemia in children continues to be a major public health challenge in developing countries and particularly in Sub-Saharan Africa. Anemia has serious consequences on the growth and development of the children in the early stages of life. This study aimed to determine the prevalence and associated factors of anemia among children from 6 to 59 months in Togo. Data from the Togo Demographic and Health Survey 2013–2014 were used for this study. This nationally representative survey provided data on a wide range of indicators such as mother and child health, nutrition and other characteristics. Anemia status was determined using hemoglobin level (Hb < 11.0 g/dl), and the weighted prevalence of childhood anemia along with 95% confidence intervals were provided. Data were analyzed using logistic regression models to estimate odds ratios (OR) and their 95% confidence intervals (95% CI) for associated factors. Two thousand eight hundred ninety children aged 6–59 months were included in this analysis. The weighted prevalence of anemia was 70.9% [95% CI = 68.8–73.1] with 2.6% [95% CI = 2.0–3.3] of severe anemia among these children. In the multivariate analysis, the adjusted odds ratio (aOR) for anemia was 0.33 [95% CI = 0.26–0.42] in children aged from 24 to 42 months and 0.22 [95% CI = 0.17–0.29] in children aged from 43 to 59 months. Children’s malaria status was strongly associated to childhood anemia with an aOR of 3.03 [95% CI = 2.49–3.68]. The secondary level of education and more for the mother was associated to childhood anemia with an aOR of 0.67 [95% CI = 0.52–0.86]. The aOR for children whose mother had anemia was 1.62 [95% CI = 1.30–2.02]. This study has highlighted the high prevalence of childhood anemia in Togo and revealed that younger children and maternal anemia were positively associated to childhood anemia whereas age of children and high level of maternal education were negatively associated to childhood anemia.

Adherence to antiretroviral therapy (ART) is beneficial in reducing the risk of emergence of HIV resistant strains. Adherence to ART among Persons Living with HIV/AIDS (PLWHA) is influenced by several factors related to the patient, the medication, and health facilities. In Togo, previous studies on adherence to ART have reported good adherence to ART during the first year of follow-up. However these may hide many disparities dues to cultural specificities which may differ across geographic areas of the country. We sought to determine the level of adherence to ART and document the associated factors among PLWHA at the regional hospital of Sokodé, Togo.

Inadequate immunization coverage remains a public health problem in Africa. In Togo, only 62% of children under one year of age were fully immunized in 2013. This study aimed to estimate the immunization coverage among children aged 12–23 months, and to identify factors associated with incomplete immunization status in Togo. A cross-sectional survey was conducted in the six health regions of Togo. Children aged 12 to 23 months who were living with one of their parents or guardians from selected households were recruited for the study. Data was collected using a pre-tested questionnaire through face-to-face interviews. Multilevel logistic regression analyses were performed to assess factors associated with incomplete immunization coverage. A total of 1261 households were included. Respondents were predominantly women (91.9%) and 22.8% had secondary or higher education level. Immunization cards were available for 85.3% of children. Complete immunization coverage was 72.3%, 95% confidence interval (CI): [69.7–74.8]). After controlling for both individual and contextual level variables, children whose mothers attended secondary school or above were 33% (adjusted Odds Ratio (aOR) = 0.67, CI [0.47–0.94]) less likely to have an incomplete immunization coverage compared to those with no education. The likelihood of incomplete immunization in children decreased with the increase in household’s income (aOR = 0.73, 95% CI [0.58–0.93]), children who did not have an immunization card (aOR = 13.41, 95% CI [9.19–19.57]) and those whose parents did not know that children immunization was free of charge (aOR = 1.82, 95% CI [1.00–3.30]) were more likely to have an incomplete immunization. Finally, children whose parents had to walk half an hour to one hour to reach a healthcare center were 57% (aOR = 1.57, 95% CI [1.15–2.13]) more likely to have an incomplete immunization coverage than those whose parents had to walk less than half an hour. The goal of 90% coverage at the national level has not been achieved in 2017. Innovative strategies such as using electronic cards and strengthening sensitization activities must be initiated in order to attain a complete immunization coverage in Togo.

Incompleteness of vaccination coverage among children is a major public health concern because itcontinues to sustain a high prevalence of vaccine-preventable diseases in some countries. In Togo, very few data on the factors associated with incomplete vaccination coverage among children have been published. We determined the prevalence of incomplete immunization coverage in children aged one to five years in Togo and associated factors. This was a cross-sectional study using secondary data from the 2010 Multiple Indicator Cluster Surveys (MICS4) conducted in 2010 among children aged 1 to 5 years in Togo. This survey was conducted over a period of two months from September to November, 2010. During Togo’sMICS4 survey, 2067 children met the inclusion criteria for our study. Female children accounted for 50.9 % (1051/2067) of the sample and 1372 (66.4 %) lived in rural areas. The majority of children (92.2 %; 1905/2067) lived with both parents and 30 % of the head of households interviewed were not schooled (620/2067). At the time of the survey, 36.2 % (750/2067) of the children had not received all vaccines recommended by Expanded Program on Immunization (EPI). In multivariate analysis, factors associated with incompleteness of immunization at 1 year were: health region of residences (Maritime aOR = 0.650; p = 0.043; Savanes: aOR = 0.324; p <0.001), non-schooled mother (aOR = 1.725; p = 0.002),standard of living (poor: aOR = 1.668; p = 0.013; medium: aOR = 1.393; p = 0.090) and the following characteristics of the household heads: sex (aOR = 1.465; p = 0.034), marital status (aOR = 1.591; p = 0.032), education level(non-educated: aOR = 1.435; p = 0.027. The incomplete immunization coverage among children in Togo remains high. It is necessary to strengthen health promotion among the population in order to improve the use of immunization services that are essential to reduce morbidity and mortality among under five years old children.

The objective of this study is to assess the quality of life and to identify factors associated with good global quality of life among people living with HIV/AIDS (PLWHA) in Togo. In total, 880 PLWHA with mean age (standard deviation) of 39.6 (10.1) years, were interviewed. Most of them (78.4%) were female. The global score of quality of life was ranged from 42.6 to 112, with a mean (standard deviation) estimated at 86.3 ± (13.3). More than the three-quarters (76.2%) of the participants had a good global quality of life. In multivariate analysis, secondary education level or higher (adjusted odds ratio = 1.78, 95% confident interval (CI) [1.10–2.85]), living in Kara health region (adjusted odds ratio = 4.39, 95% CI [2.94–6.57]), being on antiretroviral therapy (adjusted odds ratio = 6.99, 95% CI [4.11–11.9]) and HIV sero-status disclosure (adjusted odds ratio = 1.83, 95% CI [1.28–2.61]) were associated with a better overall quality of life (score ≥ 77.3).
