This study addresses fairness in machine learning for student academic performance prediction using the UCI Student Performance dataset. We comparatively evaluate logistic regression, Random Forest, and XGBoost, integrating the Synthetic Minority Oversampling Technique (SMOTE) to address class imbalance and 5-fold cross-validation for robust model training. A comprehensive fairness analysis is conducted, considering sensitive attributes such as gender, school type, and socioeconomic factors, including parental education (Medu and Fedu), cohabitation status (Pstatus), and family size (famsize). Using the AIF360 library, we compute the demographic parity difference (DP) and Equalized Odds Difference (EO) to assess model biases across diverse subgroups. Our results demonstrate that XGBoost achieves high predictive performance (accuracy: 0.789; F1 score: 0.803) while maintaining low bias for socioeconomic attributes, offering a balanced approach to fairness and performance. A sensitivity analysis of bias mitigation strategies further enhances the study, advancing equitable artificial intelligence in education by incorporating socially relevant factors. Full article

Introduction: Dental caries and molar–incisor hypomineralisation (MIH) are prevalent conditions affecting children’s oral health, with functional, aesthetic, and psychosocial implications. In Spain, previous studies have highlighted geographic and sociodemographic disparities in their distribution, particularly among rural and migrant populations. Objective: To characterise oral health status, in terms of caries and MIH, among 6–7-year-old children from the towns of Palos de la Frontera, Mazagón, and San Bartolomé. Methods: A cross-sectional study was conducted involving 229 children recruited from public primary schools. Sociodemographic, anthropometric, and behavioural data were collected through clinical examination and interview. Statistical analysis included univariate and multivariate logistic regression. The study protocol was approved by the Ethics Committee of Huelva. Results: The prevalence of caries (DMFT ≥ 1) was 53.3%, with mean DMFT and dft indices of 1.78 and 0.31, respectively. MIH affected 32.8% of the cohort, with a predominance in the first permanent molars (teeth 36 and 26). Multivariate analysis identified independent predictors of caries: African (OR = 7.47; 95% CI: 2.84–23.8) and European (OR = 4.56; 95% CI: 1.26–22.3) parental origin, poor oral hygiene (OR = 3.07; 95% CI: 1.60–6.03), and the presence of MIH (OR = 3.20; 95% CI: 1.64–6.42). The municipality of San Bartolomé was associated with a higher risk of MIH (OR = 2.90; 95% CI: 1.21–7.45). Conclusions: The high prevalence of caries and MIH in the Condado-Campiña district, exceeding national averages, reflects oral health inequities linked to social determinants (migrant origin, locality) and clinical factors (MIH, oral hygiene). Targeted preventive interventions are urgently needed in high-risk populations, including culturally tailored education and policies ensuring equitable access to dental care services. Full article

(1) Background: Human Papillomavirus (HPV)-associated oropharyngeal cancer is the fastest-growing head and neck malignancy, yet vaccination coverage remains suboptimal. (2) Methods: In this cross-sectional survey conducted from April 2022 to April 2023, 400 parents of patients aged 8–18 years (mean ± SD = 12.8 ± 2.6; 59.3% female) reported their child’s HPV vaccination status and willingness to initiate or complete the vaccine series at a dental clinic. For those who were not fully vaccinated, reasons for refusal were documented. (3) Results: Over half (54.5%, n = 218) of the children were not fully vaccinated. Notably, 21% (46/218) of parents indicated an immediate willingness to vaccinate their child if the dentist offered it—a significant potential for improvement compared to general healthcare settings. Reported barriers included preference for a physician’s office (43.6%), indecision (20.3%), unspecified concerns (14.5%), safety worries (8.1%), and religious objections (5.2%). Male and younger patients (9–11 years) showed significantly lower vaccination coverage (p < 0.05). (4) Conclusions: Dentists can substantially impact public health by integrating immunization counseling, interprofessional collaboration, and vaccine administration, thereby addressing critical gaps in HPV-related cancer prevention. These findings highlight the opportunity for dental offices to enhance vaccination rates and prompt further research, education, and policy initiatives to advance the oral and general health of our patients.

Background/Objectives: This study aimed to investigate the association between serum ferritin levels and functional impairment in children with Attention Deficit Hyperactivity Disorder (ADHD). In addition, we investigated whether this relationship remained significant after controlling for core symptom severity and examined the correlations between ferritin levels and ADHD symptom levels. Methods: The sample included 88 children aged 6–13 years: 44 diagnosed with ADHD and 44 healthy controls (HCs) matched for age and sex. ADHD symptom severity was assessed using Turgay’s DSM-IV-Based ADHD and Disruptive Behavior Disorders Screening Scale (T-DSM-IV-S; parent-report) and the Clinical Global Impression—Severity (CGI-S) scale (clinician-rated). Functional impairment was measured using the Weiss Functional Impairment Rating Scale—Parent Report (WFIRS-P). Serum ferritin levels were determined through venous blood samples. Statistical analyses included group comparisons, Spearman correlations, and partial correlations controlling for symptom severity. Results: Children with ADHD had significantly lower serum ferritin levels and higher levels of both symptom severity and functional impairment compared to HCs. Ferritin levels were negatively correlated with ADHD symptom severity and with functional impairment in the Life Skills domain. However, after controlling for ADHD symptom severity, the association with Life Skills was no longer statistically significant. Conclusions: Ferritin levels were found to be associated with both ADHD symptom severity and functional impairment in the Life Skills domain. However, this relationship was not independent of symptom severity, suggesting that core ADHD symptoms may mediate the impact of iron status on daily functioning. Due to the study’s limitations (e.g., cross-sectional design, small sample size, gender imbalance, and lack of inflammatory and dietary data), our findings should be interpreted with caution, as they do not establish causality or resolve the ongoing inconsistencies in the literature. These results underscore the relevance of iron metabolism in the clinical presentation of ADHD and highlight the need for future research to determine whether improving iron status could serve as an adjunctive strategy in the management of functional impairments in this population.

Objective: To explore the experiences and self-efficacy of parent-caregivers providing care for a child with a tracheostomy tube. Study Design: Parent-caregivers completed surveys and participated in semi-structured interviews about their experiences learning to care for their child with a tracheostomy tube. Survey data were analyzed using descriptive statistics. Interviews were transcribed verbatim and analyzed thematically through coding. Results: Fifteen parent-caregivers participated in the survey, 13 of whom completed an interview. After receiving a tracheostomy, children were hospitalized a median of 6 months prior to discharge home. At the time of our study, children had been home for a median of 3.5 years. Parent-caregivers felt more prepared to perform routine daily care compared to triaging a change in medical status. Parent-caregiver self-efficacy in performing tracheostomy care skills improved with experience at home. Four themes were identified from interviews: new identity formation, enduring education, child and family biopsychosocial support, and establishing normalcy. Parent-caregivers shared that education was more than just acquiring skills; it also involved discovering diverse ways of learning and building confidence in one’s own abilities to fulfill the many types of roles they serve to successfully care for and keep their child safe while supporting their social and emotional needs as parent-caregivers. Conclusions: Parent-caregivers’ reflections on their experiences provide critical insight into their psychosocial needs and challenges in providing care to children with tracheostomies. Further investigation of lived experiences is vital to shaping a community that can support families of medically complex children. Full article

This study examines how U.S. immigration policies enact legal violence and multigenerational punishment through the spousal reunification process, particularly in mixed-status, transnational families. Building on the concept of “deportability,” we introduce “importability” to describe a beneficiary’s potential to secure permanent residency, which varies according to social markers such as race, gender, and region of origin. Drawing from a content analysis of threads on the Immigration Pathways (IP) web forum, we analyze discussions among U.S. citizen petitioners navigating marriage-based green card applications, with a focus on experiences involving administrative processing (AP) (i.e., marriage fraud investigations). Our findings show that couples who do not align with the state’s conception of “proper” family—particularly U.S. citizen women petitioning for Black African partners—face intensified scrutiny, long delays, and burdensome requirements, including DNA tests and surveillance. These bureaucratic obstacles produce prolonged family separation, financial strain, and diminished sense of belonging, especially for children in single-parent households. Through the lens of “importability,” we reveal how legal violence and multigenerational punishment of immigration policies on mixed-status families beyond deportation threats, functioning as a gatekeeping mechanism that disproportionately affects marginalized families. This research highlights the understudied consequences of immigration policies on citizen petitioners and contributes to a broader understanding of inequality in U.S. immigration enforcement.

This study investigates the complex relationship between levels of religiosity and attitudes toward secularization among individuals receiving higher religious education in Türkiye. Secularization is defined as the diminishing influence of religion in public life and the rise of critical attitudes toward religious norms, a process that accelerated particularly during the modernization period following the establishment of the Republic. The primary aim of the research is to analyze whether there is a significant relationship between secular attitudes and the perceived influence of Islam among theology faculty students. The study employs a quantitative, descriptive survey design and includes a sample of 380 undergraduate, graduate, and doctoral students from the faculties of theology at Kocaeli, Sakarya, Marmara, and Istanbul universities. Data were collected using the “Perceived Influence of Religion Scale” and the “Secular Attitude Scale,” both of which demonstrated acceptable reliability (Cronbach’s Alpha = 0.70). Demographic variables such as age, gender, marital status, parental education level, type of education (formal or distance), and economic status were also incorporated into the analysis. The findings revealed statistically significant differences based on marital status, parental education level, type of education program, and previous educational background. For instance, single students reported perceiving a higher influence of religion compared to their married counterparts, while students with fathers who held university degrees perceived a lower influence of religion. These results offer valuable insights into how modern social transformations influence religious attitudes and practices. Full article

Background/Objectives: Childhood stunting remains a critical public health issue in low- and middle-income countries. Despite Malaysia’s economic growth, there is limited large-scale evidence on the determinants of stunting among children from infancy to primary school age. This cross-sectional study, part of South East Asian Nutrition Surveys II (SEANUTS II), aimed to determine sociodemographic and environmental risk factors for stunting among 2989 children aged 0.5–12 years. Methods: Children were recruited from four regions in Peninsular Malaysia (Central, East Coast, 2022–2030Northern, Southern). Standing height or recumbent length was measured, and stunting was classified based on WHO criteria (height-for-age Z-score below −2 standard deviations). Parents reported information on socioeconomic status, sanitation facilities, and hygiene practices. Multivariate binary logistic regression was used to determine the determinants of stunting. Results: Stunting prevalence was 8.9%, with infants (aOR = 2.92, 95%CI:1.14–7.52) and young children (aOR = 2.92, 95%CI:1.80–4.76) having higher odds than school-aged children. Key biological predictors included low birth weight (aOR = 2.41; 95%CI:1.40–4.13) and maternal height <150 cm (aOR = 2.24; 95%CI:1.36–3.70). Chinese (aOR = 0.56; 95%CI:0.35–0.88) and Indian children (aOR = 0.16; 95%CI:0.05–0.52) had a lower risk of stunting compared to Malays. Conclusions: This study highlights the ongoing challenge of childhood stunting in Malaysia, with age, birth weight, ethnicity, and maternal height identified as key determinants. These findings call for early identification of at-risk households and targeted support, especially through education and financial aid to foster healthy child growth. Full article

Background: Childhood hearing loss is a public health problem of critical importance associated with speech development, academic achievement, and quality of life. Parents’ awareness and knowledge about risk factors contribute to early detection and timely intervention.  Objective: This study aims to examine Jordanian mothers’ knowledge of childhood hearing loss risk factors and investigate the impact of education level and socioeconomic status (SES) on the accuracy and comprehensiveness of this knowledge with the moderating effect of health literacy. Material and Methods: The approach employed an embedded mixed-methods design with a dominant quantitative strand supported by qualitative data, utilizing quantitative surveys (n = 250), analyzed using structural equation modeling (SEM) in SmartPLS, and qualitative interviews (n = 10), analyzed thematically to expand upon the quantitative findings by exploring barriers to awareness and healthcare-seeking behaviors. Results: The accuracy and comprehensiveness of knowledge of hearing loss risk factors were also positively influenced by maternal knowledge of hearing loss risk factors. Maternal knowledge was significantly associated with both education level and socioeconomic status (SES). Furthermore, maternal knowledge and accuracy were significantly moderated by health literacy, such that mothers with higher health literacy exhibited a stronger relationship between knowledge and accuracy. Qualitative findings revealed that individuals encountered barriers to accessing reliable information and comprehending medical advice and faced financial difficulties due to limited options for healthcare services. Conclusions: These results underscore the need for maternal education programs that address specific issues, provide simplified healthcare communication, and enhance access to pediatric audiology services. Future research should explore longitudinal assessments and intervention-based strategies to enhance mothers’ awareness and detect early childhood hearing loss. Full article

Parental attention and care is essential for children and adolescents who are unable to take care of their own oral health. There have been studies on the characteristics of mothers and the oral conditions of children in Korea, but there are very few previous studies that report on the oral health status of children according to the employment status of mothers. The aim of this study was to investigate the relationship between maternal employment and educational status and children’s oral health. Using data from the 10th Panel Study on Korean Children (PSKC), we analyzed the association between maternal employment and education status and the occurrence of dental caries among 1175 nine-year-old Korean children. The relationship was examined through cross-tabulation and logistic regression analysis. After adjusting for the mother’s age, parental style, parental relationship, family talk time, family meal time, leisure time, area of residence, and household income, the study found that children with working and studying mothers were 1.159 times more likely to have dental caries than children with non-working and non-studying mothers. The relationship between maternal employment and educational status and children’s oral health was confirmed. Based on the results of this study, it is expected that systematic follow-up studies will be needed to better understand the association and causal relationship between dental caries and oral disease in children according to whether mothers are employed or educated.

School readiness during early childhood is crucial for future academic success. Existing guidelines recommend a comprehensive approach. This concurrent validation study developed a School Readiness Index (SRI) with five readiness domains: early learning skills, approach to learning, cognitive skills, socioemotional development, and physical health. Through a cross-sectional comparative design, the school readiness skills of 119 Puerto Rican children (63 males, 56 females) aged 54–65 months were assessed using standardized tests (e.g., Batería IV Woodcock-Muñoz and NIH Toolbox Cognition Battery), parental questionnaires (e.g., Ages and Stages Questionnaire-3), and physical health assessments. Each measure was scored and classified using a binary coding system (0 and 1) based on participant abilities (e.g., 1 for expected performance, 0 if below expectations). A composite SRI score was calculated using 25 indicators. Discriminant validity was assessed by comparing children’s registration status in the special education program (SEP). Sex, household income, and maternal education are key determinants of school readiness. Children registered in the SEP had significantly lower composite scores than those not registered, supporting the SRI’s discriminant validity. The SRI is a reliable tool for identifying Hispanic children from Puerto Rico who may benefit from additional support. Inclusive and multidisciplinary assessment strategies are essential.

Background: MRA is used in our center for monitoring post-treatment residual aneurysmal neck and stent patency. IV CBCT offers better spatial resolution and may provide significant advantages. Objective: This study investigates the image quality of IV CBCT compared to that of MRA for the follow-up of intracranial aneurysms. Materials and Methods: In this prospective cohort study, 97 patients (mean age: 63.1 ± 11.7; 75 women and 22 men) with 114 treated cerebral aneurysms were included from July 2023 to April 2024. All patients underwent IV CBCT and MRA on the same day. Two neurointerventional radiologists assessed image quality using a five-point Likert scale on two separate occasions six weeks apart. Diagnostic values were evaluated across six parameters. Intra-observer and inter-observer agreements were calculated. Subgroup analyses were performed. Results: Overall, IV CBCT and MRA are comparable in terms of their ability to assess parent vessel status and the degree of artifacts (p > 0.05) though MRA shows a slight advantage in evaluating residual aneurysmal neck (p = 0.05). For clipped aneurysms, IV CBCT is superior in assessing residual aneurysmal neck (OR = 16.0, p < 0.001) and parent vessel status (OR = 15.1, p < 0.001) with significantly fewer artifacts (OR > 100, p < 0.001). For aneurysms solely treated with stents, IV CBCT is superior in assessing residual aneurysmal neck (OR > 20, p = 0.002) and parent vessel status (OR > 20, p = 0.002) with significantly fewer artifacts (OR > 20, p = 0.002). IV CBCT outperforms MRA in evaluating stent struts and the vessel wall status of a stented segment when MRA is non-diagnostic. Conclusions: IV CBCT and MRA have their own strengths and roles in the follow-up of post-treatment intracranial aneurysms. Overall, IV CBCT is superior in terms of its assessment of intracranial aneurysms treated solely with stents or surgical clips. Full article

Background/Objectives: Early childhood anemia is a severe public health concern and the most common blood disorder worldwide, especially in emerging countries. This study examines the sources of childhood anemia in Ghana through various societal, parental, and child characteristics. Methods: This research used data from the 2022 Ghana Demographic and Health Survey (GDHS-2022), which comprised 9353 children. Using STATA 13 and R 4.4.2 software, we analyzed maternal, social, and child factors using a model-building procedure, logistic regression analysis, and machine learning (ML) algorithms. The analyses comprised machine learning methods including decision trees, K-nearest neighbor (KNN), logistic regression, and random forest (RF). We used discrimination and calibration parameters to evaluate the performance of each machine learning algorithm. Results: Key predictors of childhood anemia are the father’s education, socioeconomic status, iron intake during pregnancy, the mother’s education, and the baby’s postnatal checkup within two months. With accuracy (94.74%), sensitivity (82.5%), specificity (50.78%), and AUC (86.62%), the random forest model was proven to be the most effective machine learning predictive model. The logistic regression model appeared second with accuracy (67.35%), sensitivity (76.16%), specificity (56.05%), and AUC (72.47%). Conclusions: Machine learning can accurately predict childhood anemia based on child and paternal characteristics. Focused interventions to enhance maternal health, parental education, and family economic status could reduce the prevalence of early childhood anemia and improve long-term pediatric health in Ghana. Early intervention and identifying high-risk youngsters may be made easier with the application of machine learning techniques, which will eventually lead to a healthier generation in the future.

Background: Adolescent girls and young women (AGYW) who engage in alcohol and substance abuse face more significant health and social consequences compared to the general population. This study evaluated the prevalence and associated factors of alcohol abuse and substance use among AGYW in Namibia. Methods: We conducted a retrospective analysis of programmatic data from AGYW aged 10–24 who participated in the Determined, Resilient, Empowered AIDS-free, Mentored, and Safe (DREAMS) component of the Reducing HIV Vulnerability: Integrated Child and Youth Health (REACH) Project HOPE Namibia from March to December 2024. Data analysis was conducted employing chi-squared tests alongside binomial and multinomial logistic regression. Results: Among the 19,662 participants included in this analysis, 2068 (10.5%) abused alcohol and/or substances in the previous six months. Participants who were HIV-negative or did not know their status (AOR = 1.57, 95% CI (1.15–2.14), and AOR = 1.50, 95% CI (109–2.07), respectively), from outside Windhoek, those who had failed or repeated school in the previous year (COR = 1.77, 95% CI (1.54–2.05)), those not disabled (AOR = 1.27, 95% CI (1.06–1.52)), those who had dropped out of school or had completed their studies, and those with no adult emotional support (AOR = 1.25, 95% CI (1.11–1.40)), were more likely to have abused alcohol and/or substances recently. In contrast, participants who were not depressed were less likely to have recently abused alcohol and substances. Conclusions: The prioritization of strategies to identify AGYW experiencing depression and to provide them with treatment is essential. Moreover, it is important to encourage parents and guardians to provide emotional support to AGYW, as it prevents them from abusing alcohol and substances. Full article

Background: A national study from China in 2023 predicted that the prevalence of overweight and obesity among children aged 7–18 will increase from 23.4% in 2019 to 32.7% by 2030. Objectives: This study aimed to investigate the longitudinal association between parental feeding practices and children’s body composition and weight status, and to assess the mediation effect of parental feeding practices in the relationship between socioeconomic status and childhood body composition. Methods: This longitudinal observational study was conducted between September and November 2021 in eight primary schools located in Luohu District, Shenzhen. Baseline and two follow-up surveys were administered annually during the same period from 2021 to 2023 (with one-year intervals). A total of 620 third-grade students (aged 8–10 years at baseline) and their parents were ultimately included in the study. Associations between parental feeding practices and children’s weight status and body composition were analyzed using mixed-effects models. The mediation effect of parental feeding practices on the relationship between socioeconomic status and childhood body composition was assessed through bootstrapping analysis. Results: At follow-up, a significant upward trend in the prevalence of central obesity among children was observed. Among all parental feeding dimensions, perceived child weight (PCW) demonstrated a strong association with central obesity after Bonferroni correction (OR = 1.33, 95% CI = 1.16, 1.51); similarly, monitoring (MN) and concern about child weight (CN) were both significantly associated with central obesity as risk factors for central obesity (OR = 1.14, 95% CI = 1.06, 1.23; OR = 1.16, 95% CI = 1.07, 1.27), both p < 0.001. These associations were modified by baseline child sex, parental BMI, and maternal and paternal education levels. However, restriction (RST) was not significantly associated with either body composition or weight status. The relationship between family socioeconomic status (SES) and childhood overweight and obesity was mediated by pressure to eat (PE) (p < 0.05). Conclusions: MN, PCW, and CN are associated with an increased risk of obesity in children. However, no significant association was found between parental feeding practices and changes in children’s body composition. Full article
