Introduction: In recent years, the use of dietary supplements has increased in all age groups. Parents may also use these supplements for their children for different reasons. This study aims to determine the use of dietary supplements by children, the factors affecting this use, and the attitudes of parents about these products. Methods: A total of 1038 children aged 2–18 years without any chronic disease who presented to the pediatric outpatient clinics of Ege University Children’s Hospital were included in this study. Parents (n = 1000) who agreed to participate in the study were interviewed face-to-face, and a comprehensive questionnaire including questions about children’s use of dietary supplements, sociodemographic characteristics, and parents’ attitudes towards dietary supplements was administered. Analyses were performed with SPSS 25.0. Results: The mean age of the children included in our study was 8.6 ± 4.8 years, and 51% (n = 510) were male. It was found that 32.5% of the children used nutritional supplements, and vitamin–mineral preparations (23.2%) were the most frequently used. Omega-3 (19.3%) and immune support products (9.4%) were the second and third most frequently used supplements, respectively. A significant relationship was found between the use of dietary supplements and the child’s age, body weight, body mass index, parents’ educational level, being health worker, and economic status (p < 0.05). It was found that most of the families thought that vitamin–mineral and omega-3 products were beneficial for growth and development and that they received information from doctors most frequently before taking these products. However, it was found that families followed the media as the second most frequent source of information for these products. Conclusions: Approximately one-third of the children in our study use dietary supplements. It is very important to raise awareness among families about the use of these products when necessary and with the recommendation of a physician. To prevent families from using dietary supplements that are not necessary for their children, especially due to misinformation in the media, pediatricians should provide correct information to parents about these products at every clinic visit. A concerted effort is needed from policy makers, media organizations, and health care providers to guide the safe use of DS. The results obtained from this study will shed light on future randomized controlled prospective studies

Child abuse and neglect is a public health problem and usually associated with family dysfunction due to multiple psychosocial, individual, and environmental factors. The diagnosis of child abuse may be difficult and require a high index of suspicion on the part of the practitioners encountering the child and the family. System-related factors may also enable abuse or prevent the early recognition of abuse. Child abuse and neglect that goes undiagnosed may give rise to chronic abuse and increased morbidity-mortality. In this report, we present two siblings who missed early diagnosis and we emphasize the importance of systems issues to allow early recognition of child abuse and neglect.

Aim: To evaluate using different iron preparations for iron deficiency and/or iron deficiency anemia prophylaxis in infants and their iron status. Methods: In this study, we retrospectively evaluated the electronic patient records of 651 healthy children aged 9 to 13 months who met the inclusion criteria and who were followed up in pediatric follow-up outpatient clinics between January 2023 and June 2023. Results: A total of 651 children with a mean age of 11.2 ± 1.4 months, 54.7% of whom were boys, who met the inclusion criteria were included in the study; 56.5% of the children were using Fe + 3 salt and the others were using Fe + 2 salt, microencapsulated iron, or sucrosomial iron drops. After the fifth month of prophylaxis, when the effects of the iron preparations used on the mean laboratory values were evaluated, it was found that hemoglobin, serum iron, and ferritin levels were lower in sucrosomial iron and microencapsulated iron users compared to other preparations (p = 0.001). When statistically pairwise comparisons were made between the groups, hemoglobin and serum iron values were found to be lower in the group using sucrosomial iron compared to the groups using Fe + 2 and Fe + 3 salts (p < 0.0001). Hemoglobin and ferritin levels were higher in the group using Fe + 2 salt compared to both sucrosomial iron and microencapsulated iron groups (p < 0.0001). When the infants were evaluated according to iron status, it was found that 208 (31.9%) had iron deficiency. Iron deficiency was found to be less in infants of families who defined their economic status as rich and in infants who used iron regularly (p-values 0.044 and 0.001, respectively). Iron deficiency/iron deficiency anemia was observed at a higher rate in the group using sucrosomial iron and microencapsulated iron prophylaxis (p = 0.001). Conclusions: To prevent iron deficiency, it is very important to use appropriate iron preparations for prophylaxis and to feed foods with high iron content. Although we found that families were willing to use different iron preparations other than iron salts for their infants, the results presented herein indicate that the rate of iron deficiency was lower in patients using iron salts. However, randomized controlled studies are needed to determine whether these preparations are effective in iron prophylaxis in infants.

To determine the prevalence of adherence to iron supplementation and the risk factors for incomplete adherence during the first year of life of infants in Izmir, Turkey. In this cross-sectional study, a total of 511 infants aged 2 to 12 months who presented to the Pediatrics outpatient clinics of Ege University Children’s Hospital were included. Mothers (n = 511) who agreed to participate in the study were interviewed face-to-face and a comprehensive questionnaire including questions about the sociodemographic characteristics of the children and the family, and their adherence to iron supplementation was administered. The data obtained from 471 (92.2%) mothers who used iron supplements for their babies were subjected to further statistical analysis. Analyses were performed with SPSS 25.0. Chi-square test was used for univariate analysis and logistic regression analysis was used to determine the independent factors associated with incomplete adherence to iron supplementation. A total of 511 mothers were surveyed. Among the infants of mothers who participated in the study, 471 (92.2%) were taking iron supplementation. Of the infants who received iron supplementation, 58.3% were given iron supplementation with complete adherence. The percentage of complete adherence with iron supplementation was 35.1% between 2 and 4 months, 66.3% between 5 and 8 months, and 52.4% between 9 to 12 months. In univariate analysis, statistically significant differences were found between complete and incomplete adherence to iron supplementation in terms of infant age, time of birth, family income, maternal education, and maternal employment status (P < .001). When the data were analyzed using multivariate analysis, only maternal education level and infant age group were found to be statistically significant independent variables for complete and incomplete adherence to iron supplementation (P < .001). In populations with a high prevalence of ID, incomplete adherence to iron supplementation is a serious risk factor for ID/IDA. Although iron supplements are routinely given to infants by the Ministry of Health in Turkey, the prevalence of complete adherence to iron supplementation is low. Therefore, in order to increase the rate of complete adherence to iron supplementation, the iron supplementation status of infants should be reviewed in detail at each health child visit and families should be informed about the importance of supplementation to prevent iron deficiency.

Objective: This project explored the impact of staff training on the rates of perinatal maternal and neonatal illicit drug testing. Methods: Controlled, retrospective chart review on 1186 newborn and mother dyads from 2006 (pre-training control group) and on 1861 dyads from 2009 (post-training study group) was completed. Differences between rates of infant and mother drug testing were compared. Results: Increased drug testing rates for the mothers and infants led to increased case finding that tripled both for the mothers (13–3.7%, p < 0.001) and for the infants (0.9–2.9%, p < 0.001). Missed opportunities for newborn testing was reduced by 35 times (20.9–0.6%, p < 0.001). Conclusion: This retrospective study led to an increase in the number of documented drug-exposed newborns. This research emphasizes the importance of and encourages other hospitals to analyze the efficacy of their current protocol and staff training practices in place to ensure the best child protection services.
