Clinical Presentation and Etiologic Diagnosis of Disorders of Sex Development in Children in Senegal

Introduction: Disorders of Sex Development (DSD) refer to situations where chromosomal, gonadal or anatomical sex is atypical. We aimed to describe the baseline characteristics on clinical and etiological diagnosis of DSD in Senegalese children. Methods: This retrospective cohort study over a period of 8 years (2015-2022) included all children aged 0 to 18 years followed for DSD at the pediatric endocrinology department of NCHAR in Dakar. Sociodemographic clinical, paraclinical (genetics, imaging, hormonal) parameters were collected and analyzed with Epi Info 7.2. The description was made using position and dispersion parameters and illustrations in the form of appropriate tables and graphs. Bivariate analysis was used for associations between variables, with an alpha error risk of 5% and a CI of 95%. All ethical rules have been respected. Results: We included 102 DSD cases. Only 61 patients (59.80%) had a genetic diagnosis. Mean age at diagnosis was 31.2 ± 46.6 months. Rearing sex of child was male in 35 cases (57.38%) and female in 22 cases (36.06%) and undetermined in 4 cases (6.56%). Based on karyotype analysis, 31(50.82%) of children had 46,XY DSD, 27 (44.26%) had 46,XX DSD and three (4.92%) children with sex chromosome DSD. Etiologies were dominated by congenital adrenal hyperplasia (81.48%) and androgen insensitivity (38.71%) in 46,XX and 46,XY DSD respectively. External masculinization score > 4, palpation of a gonad, a phallus length > 2.5, a single urogenital orifice as well as ultrasound sex were associated with the XY karyotype. Conclusion: Health care professional and medical students should be trained for early diagnosis. A national guideline should be developed for diagnosis and management of DSD during and beyond the pediatric age group, and adapted to evidence and available resources. This can only be achieved if the management of DSD is supported by universal health insurance.

Adolescents' sleep mediates maternal depressive problems and parenting behaviors: daughter and son differences in a majority Black and Hispanic sample.

Parents who experience depressive symptoms are less likely to use positive parenting behaviors, in part because of sad affect and inconsistency, which can lead to disengaged parenting. Their children also are more likely to get too little sleep, get too much sleep, or have trouble sleeping, leading to increased irritability and defiance, which may make it more difficult for a parent to use clear rules and result in more harsh parenting behaviors. The current study examined whether adolescents' sleep (too little, too much, trouble sleeping) mediated the relation between maternal depression and parenting behaviors (harsh parenting, positive parenting, clear rules). Further, a child's sex was examined as a moderator (ie, moderated mediation). The sample (n = 318) consisted of mothers reporting on adolescents aged 16-18 years (mean = 16.89, standard deviation = .429; 53.4% female) from the 10th wave of the Schools and Families Educating Children Study. Measures included the Child Behavior Checklist, Center for Epidemiologic Studies Depression Scale, and the Parenting Practices Questionnaire. Too little sleep mediated the relation between maternal depressive problems and clear rules in the overall sample (β = .05) and between maternal depressive problems and positive parenting (β = .11), clear rules (β = .13), and harsh parenting (β = .14) for only sons. Too much sleep mediated the relation between maternal depressive problems and harsh parenting in the overall sample (β = .03), but no mediation occurred for sons and daughters separately. Trouble sleeping did not serve as a mediator in the overall sample but mediated the relation between maternal depressive problems and clear rules for daughters (β = .03) and between maternal depressive problems and harsh parenting for sons (β = .09). These results suggest that adolescents' sleep difficulties may be one contributing factor to why mothers who are dealing with depressive symptoms have difficulty using clear rules/positive parenting and use more harsh parenting behaviors. In addition, several of these mediations differed for sons and daughters, indicating important sex differences that may help to better inform and design intervention programs for mothers experiencing depression.

Fathers’ use of social media for social comparison is associated with their food parenting practices

Over 85% of parents use social media; however, limited research has investigated the associations between parental social media use and food parenting practices. The objectives of this study were to: 1) describe how mothers and fathers use social media focused on topics related to child feeding and family meals; and 2) examine associations between parental social media use focused on child feeding and family meals and mothers' and fathers' food parenting practices. Data were obtained from 179 mothers and 116 fathers of children aged 3–8 years enrolled in a family-based obesity prevention intervention. We used descriptive statistics to describe parents' social media use in relation to child feeding and family meals and linear regressions with generalized estimating equations to explore associations between parents' social media use and food parenting practices. Models were stratified by parent gender and adjusted for household income, parent ethnicity, parent age, child sex, and intervention status. A higher percent of mothers than fathers reported using social media to seek information related to child feeding and family meals (64.8% mothers; 25.0% fathers) and to share and compare family meals and food choices (41.9% mothers; 19.8% fathers). While social media use was not associated with food parenting practices in mothers, fathers’ social media use to share and compare family meals and food choices was associated with negative food parenting practices, i.e., greater use of food for emotional regulation (β = 0.37, p = 0.02) and greater use of food for reward (β = 0.34, p = 0.02). Study results can inform strategies to promote healthy social media use among parents of young children.

Infant regulatory problems and the quality of dyadic emotional connection—a proof-of-concept study in a multilingual sample

Background and aimsClose autonomic emotional connections with others help infants reach and maintain homoeostasis. In recent years, infant regulatory problems (RPs, i.e., crying, sleeping, and feeding or eating problems) have surged. This study has two aims: (1) Provide proof-of-concept that dyadic autonomic emotional connection between infants and parents can be reliably assessed with a brief screening, irrespective of language and culture. (2) Assess in a heterogeneous pilot sample whether the persistence of RPs during infancy is negatively associated with the quality of dyadic autonomic emotional connection.Methods30 children aged 3–68 months (47% female) and their parents (83% mothers) were assessed during regular neonatal follow-up visits in Germany. Seven (23%) dyads were immigrants whose primary language was not German. At each assessment, paediatricians asked parents about infant's crying, sleeping, and feeding or eating problems. Dyadic interactions were rated by a multilingual team with the standardised universal Welch Emotional Connection Screen (uWECS) on four dimensions (attraction, vocalisation, facial communication, sensitivity/reciprocity).ResultsAim 1: An international team of raters was trained remotely to rate the uWECS. Reliability of α > .90 with standard raters was achieved irrespective of language mismatches (i.e., all raters scored several videos with languages they did not understand). Intra-class correlation coefficients (ICCs) among five main raters for the four uWECS dimensions ranged from .98–.99. Aim 2: Infants (n = 15 assessed longitudinally) had mean RP scores of 1.20 (SD = 1.26). Dyads had mean uWECS scores of 7.06 (SD = 2.09). Linear regression analysis showed that more persistent RPs in infancy were associated with lower uWECS scores [β = -.53, 95% CI = (-1.47, -.18), p = .017], after controlling for child sex and gestational age.ConclusionThis study provides proof-of-concept that the quality of mutual autonomic emotional connection among socio-culturally and linguistically heterogeneous samples can be reliably assessed with the uWECS, a brief screening that can be easily implemented in clinical practice. Pilot data suggests that persistent RPs during infancy are negatively associated with the quality of dyadic autonomic emotional connection. Replication of these findings in larger samples is warranted. Future studies need to address how to facilitate successful emotion regulation for today's children and future generations.

Prenatal paternal anxiety symptoms predict child DHEA levels and internalizing symptoms during adrenarche.

This study examined (1) whether measures of paternal anxious and depressive symptoms collected prenatally and during a follow-up assessment when the child was in middle childhood, predict child neuroendocrine outcomes, and (2) whether neuroendocrine outcomes are intermediate factors between paternal mental health and child cognitive/behavioral outcomes. Middle childhood coincides with increased autonomy as the child transitions into grade school, and with adrenarche, as the maturing adrenal gland increases secretion of dehydroepiandrosterone (DHEA) and its sulfated metabolite (DHEA-S), hormones that are implicated in corticolimbic development which regulate emotions and cognition. Participants were recruited from a subsample of a large prospective birth cohort study (3D study). We conducted a follow-up study when children were 6-8 years old (N = 61 families, 36 boys, 25 girls). Parental symptoms of anxiety, stress and depression were assessed via validated self-report questionnaires: prenatally using an in-house anxiety questionnaire, the Perceived Stress Scale (PSS) and the Center for Epidemiologic Studies Depression (CES-D), and at the follow up, using the Beck Anxiety and Beck Depression Inventories. Children provided salivary hormone samples, and their pituitary gland volume was measured from structural Magnetic Resonance Imaging (MRI) scans. Child behaviors were measured using the Strengths and Difficulties Questionnaire and cognitive outcomes using the WISC-V. Multiple regression analyses were used to test whether paternal mental health symptoms assessed prenatally and during childhood are associated with child neuroendocrine outcomes, adjusting for maternal mental health and child sex. Indirect-effect models assessed whether neuroendocrine factors are important intermediates that link paternal mental health and cognitive/behavioral outcomes. (1) Fathers' prenatal anxiety symptoms predicted lower DHEA levels in the children, but not pituitary volume. (2) Higher prenatal paternal anxiety symptoms predicted higher child internalizing symptoms via an indirect pathway of lower child DHEA. No associations were detected between paternal anxiety symptoms measured in childhood, and neuroendocrine outcomes. No child sex differences were detected on any measure. These results highlight the often-overlooked role of paternal factors during pregnancy on child development, suggesting that paternal prenatal anxiety symptoms are associated with child neuroendocrine function and in turn internalizing symptoms that manifest at least up to middle childhood.

Relation of prenatal and postnatal PM2.5 exposure with cognitive and motor function among preschool-aged children

The literature informing susceptible periods of exposure on children's neurodevelopment is limited. We evaluated the impacts of pre- and postnatal fine particulate matter (PM2.5) exposure on children's cognitive and motor function among 1303 mother-child pairs in the Spanish INMA (Environment and Childhood) Study. Random forest models with temporal back extrapolation were used to estimate daily residential PM2.5 exposures that we averaged across 1-week lags during the prenatal period and 4-week lags during the postnatal period. The McCarthy Scales of Children's Abilities (MSCA) were administered around 5 years to assess general cognitive index (GCI) and several subscales (verbal, perceptual-performance, memory, fine motor, gross motor). We applied distributed lag nonlinear models within the Bayesian hierarchical framework to explore periods of susceptibility to PM2.5 on each MSCA outcome. Effect estimates were calculated per 5 μg/m3 increase in PM2.5 and aggregated across adjacent statistically significant lags using cumulative β (βcum) and 95% Credible Intervals (95%CrI). We evaluated interactions between PM2.5 with fetal growth and child sex. We did not observe associations of PM2.5 exposure with lower GCI scores. We found a period of susceptibility to PM2.5 on fine motor scores in gestational weeks 1–9 (βcum = −2.55, 95%CrI = −3.53,-1.56) and on gross motor scores in weeks 7–17 (βcum = −2.27,95%CrI = −3.43,-1.11) though the individual lags for the latter were only borderline statistically significant. Exposure in gestational week 17 was weakly associated with verbal scores (βcum = −0.17, 95%CrI = −0.26,-0.09). In the postnatal period (from age 0.5–1.2 years), we observed a window of susceptibility to PM2.5 on lower perceptual-performance (β = −2.42, 95%CrI = −3.37,-1.46). Unexpected protective associations were observed for several outcomes with exposures in the later postnatal period. We observed no evidence of differences in susceptible periods by fetal growth or child sex. Preschool-aged children's motor function may be particularly susceptible to PM2.5 exposures experienced in utero whereas the first year of life was identified as a period of susceptibility to PM2.5 for children's perceptual-performance.

Employees’ preferred extent for working from home – relationships with emotional job and childcare demands

PurposeTo better understand employees’ preferred extent for working from home (WFH) setting that implies physical distance from clients and co-workers and enhanced physical proximity to others at home, this study, relying on job-demands resources (J-DR) theory, aims to investigate the relationships between this preference with both the perceived increase in emotional job demands and the exposure to childcare demands. Thus, this study aims to investigate the mediating role of perceived job difficulty in the relationship between emotional job demands and the preferred extent for WFH, and the moderating role of gender in the relationship between the number of children and the preferred extent for WFH.Design/methodology/approachA total of 239 employees who began WFH during the pandemic completed an online survey. Structural equation modelling was conducted to analyse the data and test the hypotheses.FindingsAs expected, an increase in emotional job demands had a significant negative indirect association with the preferred extent for WFH, through perceived increase in job difficulty. Furthermore, the number of children was negatively related to the preferred extent for WFH among male but not female employees.Practical implicationsThe findings provide insights for promoting employees’ preferred extent for WFH.Originality/valueThe study points to a relationship between emotional job demands and employee attitudes towards WFH in terms of increased job difficulty and the preferred extent for WFH. It also points to the need to investigate the interaction between sex and number of children to understand employees’ preferred extent for WFH.

Caregiver mental health and school-aged children's academic and socioemotional outcomes: Examining associations and mediators in Northern Ghana.

While there is a strong link between caregiver mental health, caregiver engagement, and child development, limited research has examined the underlying mechanisms of these associations in Africa. We examined the mediating role of dimensions of caregiver engagement in the association of caregiver psychological distress with children's academic and socioemotional outcomes in Ghana. Data came from 4,714 children (aged 5-17 years) and their caregivers in five regions of northern Ghana. Caregiver psychological distress and engagement (i.e., engagement in education, emotional supportiveness, and parenting self-efficacy) were self-reported by children's primary caregiver. Children's academic (literacy and numeracy) and socioemotional (prosocial skills and socioemotional difficulties) outcomes were directly assessed using validated measures. Structural equation modelling was used to estimate mediation models. We tested moderation by caregiver exposure to formal education, child's age, and child's sex. Fourteen percent of caregivers experienced elevated psychological distress. Higher levels of psychological distress were associated with children's poorer literacy and numeracy skills, and higher socioemotional difficulties, but not prosocial skills. The mediating role of caregiver engagement varied by caregiver exposure to formal education but not child's age or sex. Caregiver engagement in education explained the association between psychological distress and children's literacy skills (but not numeracy or socioemotional) in families where the caregiver had no formal education (indirect effect: β = 0.007 [95% CI: 0.000, 0.016]), explaining 23% of the association. No mediator explained the association of psychological distress with child outcomes among families where the caregiver had some formal education. The mechanisms through which caregiver psychological distress is associated with child outcomes in rural Ghana differ as a function of caregivers' exposure to formal education. These results highlight the importance of developing multi-component and culturally-sensitive programs to improve child outcomes. Further research in similar contexts is needed to advance scientific understanding on how to effectively promote child and family wellbeing.

Association of maternal constipation and risk of atopic dermatitis in offspring.

Objectives: Atopic dermatitis (AD) is a chronic and relapsing dermatologic disease that can affect individuals of all ages, including children and adults. The prevalence of AD has increased dramatically over the past few decades. AD may affect children's daily activities, increase their parents' stress, and increase health expenditure. Constipation is a worldwide issue and may affect the gut microbiome. Some research has indicated that constipation might be associated with risk of atopic disease. The primary objective of this retrospective cohort study was to extend and to explore the link between maternal constipation and risk of atopic dermatitis in offspring. Methods: Using the Longitudinal Health Insurance Database, a subset of Taiwan's National Health Insurance Research Database, we identified 138,553 mothers with constipation and 138,553 matched controls between 2005 and 2016. Propensity score analysis was used matching birth year, child's sex, birth weight, gestational weeks, mode of delivery, maternal comorbidities, and antibiotics usage, with a ratio of 1:1. Multiple Cox regression and subgroup analyses were used to estimate the adjusted hazard ratio of child AD. Results: The incidence of childhood AD was 66.17 per 1,000 person-years in constipated mothers. By adjusting child's sex, birth weight, gestational weeks, mode of delivery, maternal comorbidities, and received antibiotics, it was found that in children whose mother had constipation, there was a 1.26-fold risk of AD compared to the children of mothers without constipation (adjusted hazard ratio [aHR]: 1.26; 95% CI, 1.25-1.28). According to subgroup analyses, children in the maternal constipation group had a higher likelihood of AD irrespective of child's sex, birth weight, gestational weeks, mode of delivery, and with or without comorbidities, as well as usage of antibiotics during pregnancy. Compared to the non-constipated mothers, the aHR for the constipated mothers with laxative prescriptions <12 and ≥12 times within one year before the index date were 1.26; 95% CI, 1.24 -1.28 and 1.40; 95% CI, 1.29-1.52, respectively. Conclusion: Maternal constipation was associated with an elevated risk of AD in offspring. Clinicians should be aware of the potential link to atopic dermatitis in the children of constipation in pregnant women and should treat gut patency issues during pregnancy. More study is needed to investigate the mechanisms of maternal constipation and atopic diseases in offspring.

Prenatal exposures to phthalates and life events stressors in relation to child behavior at age 4–6: A combined cohort analysis

Prenatal exposures to chemical and psychosocial stressors can impact the developing brain, but few studies have examined their joint effects. We examined associations between prenatal phthalate exposures and child behavior, hypothesizing that prenatal stressful life events (PSLEs) may exacerbate risks. To do so, we harmonized data from three U.S. pregnancy cohorts comprising the ECHO-PATHWAYS consortium. Phthalate metabolites were measured in single mid-pregnancy urine samples. When children were ages 4–6 years, mothers completed the Child Behavior Checklist (CBCL), from which a Total Problems score was calculated. Mothers additionally provided recall on their exposure to 14 PSLEs during pregnancy. Primary models examined problem behaviors in relation to: (1) phthalate mixtures calculated through weighted quantile sums regression with permutation test-derived p-values; and (2) joint exposure to phthalate mixtures and PSLEs (counts) using interaction terms. We subsequently refitted models stratified by child sex. Secondarily, we fit linear and logistic regression models examining individual phthalate metabolites. In our main, fully adjusted models (n = 1536 mother–child dyads), we observed some evidence of weak main effects of phthalate mixtures on problem behaviors in the full cohort and stratified by child sex. Interaction models revealed unexpected relationships whereby greater gestational exposure to PSLEs predicted reduced associations between some phthalates (e.g., the metabolites of di-2-ethylhexyl phthalate, di-n-octyl phthalate, di-iso-nonyl phthalate) and problem behaviors, particularly in males. Few associations were observed in females. Additional research is needed to replicate results and examine potential mechanisms.

Prenatal Metal Exposures and Child Social Responsiveness Scale Scores in 2 Prospective Studies.

Prenatal exposure to metals is hypothesized to be associated with child autism. We aim to investigate the joint and individual effects of prenatal exposure to urine metals including lead (Pb), mercury (Hg), manganese (Mn), and selenium (Se) on child Social Responsiveness Scale (SRS) scores. We used data from 2 cohorts enriched for likelihood of autism spectrum disorder (ASD): Early Autism Risk Longitudinal Investigation (EARLI) and the Markers of Autism Risk in Babies-Learning Early Signs (MARBLES) studies. Metal concentrations were measured in urine collected during pregnancy. We used Bayesian Kernel Machine Regression and linear regression models to investigate both joint and independent associations of metals with SRS Z-scores in each cohort. We adjusted for maternal age at delivery, interpregnancy interval, maternal education, child race/ethnicity, child sex, and/or study site. The final analytic sample consisted of 251 mother-child pairs. When Pb, Hg, Se, and Mn were at their 75th percentiles, there was a 0.03 increase (95% credible interval [CI]: -0.11, 0.17) in EARLI and 0.07 decrease (95% CI: -0.29, 0.15) in MARBLES in childhood SRS Z-scores, compared to when all 4 metals were at their 50th percentiles. In both cohorts, increasing concentrations of Pb were associated with increasing values of SRS Z-scores, fixing the other metals to their 50th percentiles. However, all the 95% credible intervals contained the null. There were no clear monotonic associations between the overall prenatal metal mixture in pregnancy and childhood SRS Z-scores at 36 months. There were also no clear associations between individual metals within this mixture and childhood SRS Z-scores at 36 months. The overall effects of the metal mixture and the individual effects of each metal within this mixture on offspring SRS Z-scores might be heterogeneous across child sex and cohort. Further studies with larger sample sizes are warranted.

Effect of Child Economic Contribution to Farming Households’ Income in Akwa Ibom State. Nigeria

This paper examines effect of child economic contribution to farming households’ income in Akwa Ibom State. The study adopted a non-experimental design (cross sectional Survey). Data were obtained using a multi-stage sampling procedure. The study used logistic regression and propensity score matching to assess the effect of child’s economic contribution to farming households’ income in the study area. Child’s economic contributions significantly related with sex of child and parent marital status, suggesting, gender and family structure play a role in child economic contributions to households’ income. Parental Educational status, Parental monthly expenditure, Household size, Household resource deprivation status, Family socio-economic well-being and drive for economic wealth creation were found to explain child work involvement in farming households. The PSM outcome indicated that the mean difference of respondents who involved children in work and those who did not, remained the same, (0.00018). And the T test result shows that there is no significant effect between child involvement in work and child economic contribution to households’ income. In conclusion, it was discovered that there was no positive effect of child involvement in work and households’ income. Therefore, the children should be trained through school, skill programmes to develop their human capital potentials. As this is going to be the only way they can impact positively on the households and the economy at large through expertise skill. And Businesses should be encouraged to adopt ethical business practices and eliminate child labour from their supply chain. Promote the right of children and ensure that policies and practices prioritize their well-being. And the children involvement in decision making that involves them should be encouraged.

Trend and determinants of minimum dietary diversity consumption change among children aged 6-23 months in Ethiopia from 2011 to 2019: A multivariate decomposition analysis.

Sustainable Development Goals 2 target 2.2 aimed to end all forms of malnutrition by 2030. However, the prevalence of inadequate minimum dietary diversity (MDD) is high in Ethiopia and the evidence of trends and determinants of MDD consumption change among children over time is limited. Therefore, this study aimed to determine trends and determinants of MDD consumption change among children aged 6 to 23 months in Ethiopia from 2011-2019 Demographic and Health Survey (DHS) data. The study used the data on nationally representative weighted samples of 6,971, 7,467, and 3,154 children aged 6-23 months from the 2011, 2016, and 2019 rounds of the DHS. Trend and Multivariate Decomposition analysis was conducted to determine MDD consumption change from 2011-2016, and 2016-2019 into two components: one that was explained by differences in the level of the determinants (endowment), and the other component was explained by differences in the effect of the covariates on the outcome (coefficient effects). The trends analysis showed that adequate MDD consumption significantly increased from 2% to 10.41% from 2011 to 2016 but decreased from 10.41% to 7.11% from 2016 to 2019 in Ethiopia. The compositional and behavioral change factors like maternal age, occupational status of parents, sex of the household head, wealth index, residence, and sex of child statistically contributed to changes in MDD consumption from 2011 to 2016, and from 2016 to 2019 at p-value <0.05. The trend of minimum dietary diversity consumption among children aged 6 to 23 months in Ethiopia increased from 2011-2016 and decreased from 2016-2019 in the last decade. The study revealed that the changes in behavioral response and population composition contributed to MDD consumption change among children in Ethiopia. The finding highlights the urgent need for targeted interventions and policies to address the issue of MDD consumption change among young children due to population structure changes like wealth status, residence, and behavioral response related to employment, household head, and sex of the child in Ethiopia. Therefore, efforts should be geared to reduce poverty and improve maternal employment status, particularly for women, by producing equitable economic opportunities.

Personal and environmental factors and household assistance in Down syndrome: cross-sectional study.

According to a biopsychosocial framework, personal and environmental factors might be mediators or facilitators/barriers, respectively, to functioning. However, it is not known how these factors can impact independence in household chores in children/adolescents with Down syndrome (DS). This study explored whether and how personal/environmental factors are associated with the independence level in household chores of children/adolescents with DS in Brazil. Caregivers of twenty-eight children/adolescents with DS were interviewed using the CHORES and a standardized questionnaire about personal (child's age and sex) and environmental (socioeconomic level and maternal schooling) factors. Multiple linear regression analysis identified if/how these factors are associated with level of independence. For CHORES self-care and CHORES total, sex was a significant variable explaining 21.8% and 15.8%, respectively, of the variation in the outcomes. For the outcome CHORES family care none of the variables was significant. Female sex was associated with a lower need for assistance. We conclude that only the personal factor assessed related to female sex in children with DS was associated with the independence level in household chores. This finding highlights the importance of health care providers and families to encourage the independence in chores regardless of sex and promote opportunities for both boys and girls.

Approaches to sexuality in childhood from occupational therapy

Resumen El presente artículo consta de una revisión bibliográfica que tiene por objetivo describir los distintos factores que influyen en el desarrollo de la sexualidad infantil para comprenderla desde la terapia ocupacional. La problemática planteada aborda la invisibilidad de los componentes naturales y normativos de la sexualidad en la primera y segunda infancia y cómo la terapia ocupacional se aproxima a estos factores en su intervención. Para llevar a cabo esta búsqueda bibliográfica, se utilizaron variadas bases de datos y revistas de terapia ocupacional, con el fin de encontrar textos que tuvieran relación con el objetivo y problemática propuesta, los cuales fueron filtrados de acuerdo a criterios de exclusión e inclusión. De los resultados se obtiene que existe escasa información académica respecto a cómo se relacionan directamente los componentes de la sexualidad infantil con las áreas de trabajo de la terapia ocupacional. Por lo anterior se concluye que la disciplina está recientemente en la incorporación del abordaje de esta temática y se plantea la necesidad urgente de reconstruir la conceptualización de la sexualidad infantil, desde una base de derechos de la niñez y alejándose de la hegemonía de una cultura heteronormada y adultocéntrica. Se consideran los distintos factores que influyen al desarrollo de la sexualidad infantil y entendiéndola no solo como ocupación sino como parte fundamental de la identidad ocupacional, que tiene como componentes la autonomía corporal, el desarrollo socio afectivo, el placer y el disfrute, el género y las elecciones ocupacionales, los cuales guiarían el abordaje de terapia ocupacional.

Neonatal anthropometric indicators of infant growth and mortality in Burkina Faso.

Most evidence supporting screening for undernutrition is for children aged 6-59 months. However, the highest risk of mortality and highest incidence of wasting occurs in the first 6 months of life. We evaluated relationships between neonatal anthropometric indicators, including birth weight, weight-for-age Z-score (WAZ), weight-for-length Z-score (WLZ), length-for-age Z-score (LAZ) and mid-upper arm circumference (MUAC) and mortality and growth at 6 months of age among infants in Burkina Faso. Data arose from a randomised controlled trial evaluating neonatal azithromycin administration for the prevention of child mortality. We evaluated relationships between baseline anthropometric measures and mortality, wasting (WLZ < -2), stunting (LAZ < -2) and underweight (WAZ < -2) at 6 months of age were estimated using logistic regression models adjusted for the child's age and sex. Five regions of Burkina Faso. Infants aged 8-27 d followed until 6 months of age. Of 21 832 infants enrolled in the trial, 7·9 % were low birth weight (<2500 g), 13·3 % were wasted, 7·7 % were stunted and 7·4 % were underweight at enrolment. All anthropometric deficits were associated with mortality by 6 months of age, with WAZ the strongest predictor (WAZ < -2 to ≥ -3 at enrolment v. WAZ ≥ -2: adjusted OR, 3·91, 95 % CI, 2·21, 6·56). Low WAZ was also associated with wasting, stunting, and underweight at 6 months. Interventions for identifying infants at highest risk of mortality and growth failure should consider WAZ as part of their screening protocol.

Family Structure Associated with Measles-Rubella and Varicella Vaccination in Children.

Delayed vaccination is a well-studied and critical public health issue. However, limited studies have explored whether familial factors influence vaccination delay. This study aimed to determine whether family structure and comorbidities affect the refusal or delayed receipt of measles-rubella and varicella vaccines. We gathered data on all children from birth to 13 months of age between 2006 and 2020 using vaccination records linked with the administrative healthcare claims data from a Japanese city. Multivariable logistic regression analyses were conducted to examine the association of refusal or delay in receiving the first-dose measles-rubella and varicella vaccines with the following factors: the child's sex; presence of parents, siblings, and grandparents; parental and grandparental comorbidities; chronic pediatric comorbidities in the child and siblings; and year of vaccination. We identified a total of 14,241 eligible children. Refusal or delayed receipt of the first-dose measles-rubella vaccine was associated with an adjusted odds ratio of 2.46 (95% confidence interval, 1.86-3.24) for maternal absence and 1.61 (1.44-1.80) for paternal absence. Similarly, the refusal or delay in receiving the first-dose varicella vaccine was associated with an adjusted odds ratio of 2.04 (95% confidence interval, 1.01-4.16) for maternal absence and 1.37 (1.12-1.69) for paternal absence. The presence of siblings and maternal comorbidities were significantly associated with vaccination delays. The absence of a parent, the presence of siblings, and maternal comorbidities were associated with the refusal or delay in receiving measles-rubella and varicella vaccines. Strategies for vaccine recommendation should therefore consider family structure and maternal comorbidities.

The influence of demographic and socio-economic factors on non-vaccination, under-vaccination and missed opportunities for vaccination amongst children 0-23 months in Kenya for the period 2003-2014.

Vaccination is crucial in reducing child mortality and the prevalence of Vaccine-Preventable-Diseases (VPD), especially in low-and-middle-income countries like Kenya. However, non-vaccination, under-vaccination, and missed opportunities for vaccination (MOV) pose significant challenges to these efforts. This study aimed to analyze the impact of demographic and socio-economic factors on non-vaccination, under-vaccination, and MOV among children aged 0-23 months in Kenya from 2003 to 2014. A secondary data analysis of data from the Kenya Demographic Health Surveys (KDHS) conducted during this period was conducted, with a total of 11,997 participants, using a two-stage, multi-stage, and stratified sampling technique. The study examined factors such as child's sex, residence, mother's age, marital status, religion, birth order, maternal education, wealth quintile, province, child's birth order, parity, number of children in the household, place of delivery, and mother's occupation. Binary logistic regression was employed to identify the determinants of non-vaccination, under-vaccination, and MOV, and multivariable logistic regression analysis to report odds ratios (OR) and their corresponding 95% confidence intervals (CI). In 2003, the likelihood of non-vaccination decreased with higher maternal education levels: mothers who did not complete primary education (AOR = 0.55, 95% CI = 0.37-0.81), completed primary education (AOR = 0.34, 95% CI = 0.21-0.56), and had secondary education or higher (AOR = 0.26, 95% CI = 0.14-0.50) exhibited decreasing probabilities. In 2008/09, divorced/separated/widowed mothers (AOR = 0.22, 95% CI = 0.07-0.65) and those with no religion (AOR = 0.37, 95% CI = 0.17-0.81) showed lower odds of non-vaccination, while lower wealth quintiles were associated with higher odds. In 2014, non-vaccination was higher among younger mothers aged 15-19 years (AOR = 12.53, 95% CI = 1.59-98.73), in North Eastern Province (AOR = 7.15, 95% CI = 2.02-25.30), in families with more than 5 children (AOR = 4.19, 95% CI = 1.09-16.18), and in children born at home (AOR = 4.47, 95% CI = 1.32-15.17). Similar patterns were observed for under-vaccination and MOV. This information can inform strategies for bridging the gaps in immunization coverage and promoting equitable vaccination practices in Kenya.

Predicting child externalizing behavior ratings in Head Start: Investigating the impact of child and teacher influences

One of the primary goals of early education is to promote overall school readiness, especially for children most at risk for educational challenges. However, there is a persistent disparity in equitable access to high quality early learning environments. This is due in part to children being suspended or expelled for displaying challenging behaviors even though for many children, some of these behaviors may be developmentally appropriate. The effects of exclusionary discipline can have long-term implications for their overall emotional and social development. Racial and gender-based disparities in school discipline begin as early as preschool. Some of these disparities can stem from disproportionality in teachers’ perceptions of children's behaviors. The ways in which teachers perceive and subsequently respond to preschoolers’ behavior have significant implications for children's experience in the classroom and are an important link in understanding decision-making pathways related to preschool expulsion. The goal of the present study was to examine factors that might predict teacher perceptions (i.e., ratings) of child externalizing (hyperactive and aggressive) behaviors. This study analyzed secondary data from a nationally representative study of Head Start. Findings indicated there were differences in how teachers rated children's externalizing behaviors based on child's sex and race. Further, a teacher's field of study, beliefs about family engagement, and attitudes toward Developmentally Appropriate Practices significantly predicted their ratings of children's aggressive and hyperactive behaviors. Policy recommendations are discussed.

Analysis of Correlated Outcomes of Anthropometric Measurements for Under-Five Children in Tanzania.

The study aimed at applying Multivariate Generalized Linear Mixed Models to examine factors associated with correlation outcomes, in particular, anthropometric measurements among under-five children in Tanzania. Three anthropometric measurements: weight-for-age (WAZ), height-for-age (HAZ), and weight-for-height (WHZ) among under-five children in Tanzania were jointly modeled to identify common factors associated with childhood malnutrition. A total of 9052 children with valid measures of height and weight were processed and analyzed. The results indicate that WAZ was correlated with HAZ (P-value < 2e-16) and WHZ (P-value < 2e-16). The Multivariate Ordered Logit Model has lower AIC = 53213.92 and BIC = 52727.95, indicating better model fit than the Multivariate Ordered Probit Model. In Tanzania, the age of the child, birth order, mother education level, child gender, mother working status, wealth index, marital status, and mother body mass index are important determinants of malnutrition among children under the age of five. Moreover, the common factors were child's age, Birth order, Mother's education attainment, child's sex, Mother working status, wealth index, Marital status, and Mother's Body Mass Index. As a result, emphasis should be placed on analyzing correlated health outcomes in order to draw conclusions about the factors that may have a mutual effect on anthropometric measurements.
