“…We then evaluated additional child-related, maternal-related, and demographic characteristics [ 15 , 16 ] as potential confounders of the relationship between child clinical characteristics and child anemia. Child-related characteristics included child sex and child age.…”

“…These immediate factors may in turn be affected by distal factors (e.g., environmental conditions affecting risk of malaria or poor diet), and these distal factors may themselves be associated with anemia (i.e., confounders). Confounders of child anemia, from published studies, include child-, maternal-, and demographic-related characteristics [ 15 – 18 ]. Recent child illnesses may affect inflammation, nutrient absorption, and diet [ 39 ].…”

“…Independent variables included child illness and child feeding practices. An evaluation of confounding (10% rule) was performed [ 13 , 14 ] on covariates thought to be associated with child anemia from the published literature, including child-related, maternal-related, and demographic-related characteristics [ 15 – 18 ]. Unadjusted and adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were reported for the association between anemia and risk factors.…”

Background Despite Colombia's robust well-child visits program, Colombian children and mothers still suffer from anemia, especially in populations of lower socioeconomic status. In this study, we aimed to quantify the prevalence and risk factors among mothers and their children attending their well-child visits in Apartadó, a municipality in the Urabá region of the Colombian Caribbean. Methods There were 100 mother–child pairs enrolled in this secondary data-analysis study from a health facility in the municipality of Apartadó, Urabá, Colombia, during well-child visits. Self-reported data included child illnesses in the past two weeks (diarrheal, fever, or respiratory symptoms), child feeding practices (breastfeeding, complementary feeding), child vaccinations, and demographic characteristics (mother’s and child’s age, mother’s education, marital status, race, and child sex) and socioeconomic status. Mother and child anthropometry data were collected via standardized weight and height measurements. Mother or child anemia status was collected via a blood test. Chi-squared tests and multivariable logistic regression were used to assess associations between risk factors and anemia. Result The anemia prevalence in children (74%) and mothers (47%) was higher than the Colombian national prevalence. Reported child comorbidities in the preceding two weeks were not significantly associated with child anemia and included respiratory illnesses (60%), fever (46%), and diarrhea (30%). Stunting (8%) was not significantly associated with anemia. Wasting (0%) was not observed in this study. Reported child breastfeeding and complementary feeding were also not significantly associated with child anemia. In adjusted models, the child's significant risk factors for anemia included the mother's "Mestiza" race (OR: 4.681; 95% CI: 1.258, 17.421) versus the Afro-Colombian race. Older children (25–60 months) were less likely to develop anemia than younger (6–24 months) children (OR: 0.073; 95% CI: 0.015, 0.360). Conclusions The finding of high anemia prevalence in this study advances our understanding of child and maternal anemia in populations of low socioeconomic status where health care is regularly accessed through well-child programs.

“…Particularly in low- and middle-income countries, the prevalence of anemia among children aged 6 to 59 months is greater than 40% [ 2 , 3 ]. Childhood anemia continues to be a severe issue associated with an increased risk of childhood mortality; also, children who have anemia have a high likelihood of impaired cognitive development, and anemia leads to long-term health complications [ 4 , 5 , 6 ]. As the largest developing country, China is projected to achieve a target for reducing anemia prevalence to less than 10% in children who are young.…”

Infant birth sizes are vital clinical parameters to predict poor growth and micronutrient deficiency in early life. However, their effects on childhood anemia remain unclear. We aimed to explore the associations between birth weight, crown–heel length, and head circumference with anemia in early childhood, as well as potential modification factors. This population-based prospective cohort study included 204,556 participants with singleton live births delivered at gestational ages of 28–42 weeks. A logistic regression model was used to estimate the associations of the measures of infant birth size and their Z-score with anemia under five years old. There were 26,802 (13.10%) children under five years old who were diagnosed has having anemia. Compared with children who did not have anemia, children who had anemia had a lower birth weight and smaller head circumference and a longer crown–heel length (all p-values < 0.05). After adjusting for confounders, not only birth weight (β coefficient, −0.008; 95% CI, −0.011–−0.004; p < 0.001) and head circumference (β coefficient, −0.004; 95% CI, −0.007–−0.001; p = 0.009), but also the related Z-scores were negatively associated with childhood anemia, while the trends for crown–heel length were the opposite. We further found significant interactions of folic acid use and maternal occupation with infant birth sizes. In conclusion, infants having abnormal sizes at birth are significantly associated with the risk for childhood anemia, which can be modified by folic acid use during pregnancy and maternal occupation.
