“…Extending that knowledge, the present study documents that children's age associates differently with IDA and Non-IDA and that gender possibly influence more the occurrence of IDA. Those differential associations may be related to different underlying factors of IDA and Non-IDA within those groups [49]. For instance, the increased risk of IDA observed in the 6-to-23-month group may be potentially related with the higher iron requirements in children within these age group, as also reported in other African studies [48].…”

“…Regarding genotyping, we observed that 42.5% (195/459) of the females had at least one G6PD polymorphism (B/ 49, comparatively to having a normal genotype or having the sickle cell trait), associations that weren't observed for children in the same age group with IDA. In older children (aging between 24 and 36 months) the occurrence of IDA appeared to be associated with the number of residents in the same household (OR: 0.4, CI:0.15-0.83, for living with more than 5 residents), children being moderate-to-severely stunted (OR: 2.5, CI:1.14-5.50) and having inflammation (OR:4.3, CI: 1.69-11.02).…”

Background: Angola is one of the southern African countries with the highest prevalence of anaemia. Identifying anaemia determinants is an important step for the design of evidence-based control strategies. In this study, we aim at documenting the factors associated with Iron Deficiency Anaemia (IDA) in 948 children recruited at the Health Research Center of Angola study area during 2015. Methods: Data on demographic, socioeconomic and parental practices regarding water, sanitation, hygiene, malaria infection and infant and young child feeding were collected, as well as parasitological, biochemical and molecular data. Total and age-stratified multivariate multinomial regression models were fitted to estimate the magnitude of associations between anaemia and its determinants. Results: Anaemia was found in 44.4% of children, of which 46.0% had IDA. Overall, regression models associated IDA with age, gender and inflammation and non-IDA with age, zinc deficiency and overload, P. falciparum infection, sickle cell trait/anaemia. Among 6-to-23-month-old children IDA was associated with continued breastfeeding and among 24-to-36-month-old children IDA was associated with stunting. Furthermore, zinc deficiency was associated with non-IDA among both age groups children. Inflammation was associated with IDA and non-IDA in either 6-to-23 and 24-to-36 months old children. Conclusion: The main variables associated with IDA and non-IDA within this geographic setting were commonly reported in Africa, but not specifically associated with anaemia. Additionally, the associations of anaemia with inflammation, zinc deficiency and infections could be suggesting the occurrence of nutritional immunity and should be further investigated. In age groups, zinc overload was observed to protect under 6 months children from Non-IDA, while continued breastfeeding was associated with increased IDA prevalence in 6-to-23 months children, and stunting was suggested to increase the odds of IDA in 24-to-36 month children. This site-specific aetiology profile provides an essential first set of evidences able to inform the planification of preventive and corrective actions/programs. Nevertheless, regional and country representative data is needed.

“…This is a very stretched and demanding target considering that the African region is a developing region with inadequate resources. A study conducted by Fancony et al [ 20 ] to understand the factors associated with anemia and the interventions implemented to prevent this condition showed that the progress of implementing interventions is slow and this may be due to different reasons including the economy. This indicates the necessity of collaboration to ensure the implementation of interventions is achieved.…”

Anemia is characterized as a condition where there is a deficient number of hematocrit, hemoglobin, or red cells in the human body. This condition affects most youngsters under five years old and pregnant women. The fundamental goal of this paper is to investigate anemia, recognize its determinants, and propose critical proposals to achieve 2030 Sustainable Development Goal with a focus on Senegal, Malawi, and Angola. This research utilized 2016 nationally representative information from Senegal, Malawi, and Angola, which involved collecting data on the demographic and health of the populaces. The Demographic and Health Survey information from Senegal, Malawi, and Angola was then merged to create a pooled sample. This statistical technique enables to generalize and compare the results. A generalized linear mixed model was utilized to decide the factors correlated with anemia among youngsters under five years in Senegal, Malawi, and Angola. The analysis was performed in SPSS and SAS software. A generalized linear mixed model results showed that, compared to youngsters aged less than 12 months, youngsters in the age interval 13–23, 24–35, 36–47, and 48–59 months are more likely to be affected by anemia (OR = 1.419, 2.282, 3.174 and 4.874 respectively). In this study, seven factors were included in the final model. However, only five were found to be significant in explaining anemia at the 5% level of significance. The generalized linear mixed model identified youngster’s age, gender, mother’s level of schooling, wealth status, and nutritional status as determinants of anemia among youngsters under five years in Senegal, Malawi, and Angola.

“…A barefoot walking is very common in young children in sub-Saharan countries [22]. Other studies have suggested that deworming may also reduce anemia indirectly [23,24]. Tis can be seen in areas with a high prevalence of intestinal worms, where anemia is prevalent due to poor nutrition and low socioeconomic status, and not due to the direct efect of the parasites.…”

Introduction. Mass deworming of preschool children is a strategy suggested to prevent soil-transmitted helminth infections in most developing countries. Nonetheless, there is a scarcity of data showing the contribution of mass deworming to a child’s nutritional status. The purpose of this study was to assess the effect of deworming on nutritional health outcomes (stunting, underweight, and anemia) in children aged 12 to 59 months. Methods. A secondary analysis of data extracted from the Tanzania Demographic and Health Survey (TDHS) 2015-16 data was carried out. A total of 7,962 children were included in this study. A multilevel logistic regression was used at a 5% level of significance to determine the individual- and community-level determinants of deworming on health outcomes among children. Results. The prevalence of underweight (62.6%), stunting (61.0%), and anemia (61.8%) was higher in children who were not dewormed than those who were dewormed. Female children were more likely to suffer from poor health outcomes (OR = 1.01 and 95% CI = 0.95–1.07) than male children. Children aged 24–35 months and 36–47 months were significantly less likely to suffer from poor health outcomes (OR = 0.89; 95% CI = 0.82–0.97 and OR = 0.88; 96% CI = 0.81–0.96, respectively; p < 0.01 ). Children from households with unimproved toilets (OR = 1.38 and 95% CI = 1.25–1.52), unimproved water sources (OR = 1.08 and 95% CI = 1.01–1.16), and living in rural areas (OR = 1.02 and 95% CI = 0.91–1.14) had higher odds for poor health outcomes. Conclusion. Deworming may be an effective technique for preventing poor health outcomes in children and the risks associated with them, such as poor growth and development.
