UNASSIGNED: Health literacy (HL) is an essential determinant of health in children. Inadequate HL causes problems for individuals and society, such as more hospitalizations, medication errors, poor health, and higher mortality and health care costs. A valid and reliable scale is needed to measure this population\'s HL. This study evaluated the cross-cultural adaptation and validation of the Persian version of the HL for School-Aged Children (HLSAC) Scale.
UNASSIGNED: In this methodological research, the HL scale of school-aged children was translated from English to Persian using the Backward-Forward translation protocol. The content validity, face validity, construct validity (Exploratory Factor Analysis [EFA] and Confirmatory factor analysis [CFA]), plus reliability, were evaluated by Internal consistency and stability methods. Two hundred forty samples from south of Tehran were selected by multi-stage sampling method to assess the construct validity. Data analysis was performed using SPSS v24 and Jamovi v2.2.
UNASSIGNED: A qualitative evaluation of face and content validity showed that experts and the target group approved all items on the scale. The results of EFA indicated the existence of one factor, explaining 47.17% of the total variance of the scale. The CFA results showed that the one-factor model of the Persian version of the HL scale for children is almost acceptable. (χ 2/df = 2.94, Root Mean Square Error of Approximation = 0.09, Normed-Fit Index = 0.89, Tucker-Lewis Index = 0.89, Comparative Fit Index = 0.92). Cronbach\'s alpha coefficient for the whole scale was 0.80, and the Intraclass Correlation Coefficient value for the whole scale was calculated as 0.78 using the single-rating, absolute-agreement, 2-way mixed-effects method.
UNASSIGNED: The study validates the HLSAC Scale, affirming its suitability for assessing HL in Persian-speaking child populations.

UNASSIGNED: Neck and shoulder pain (NSP) is common in school age, but preventative factors have not been identified. The purpose was to study whether a fitness test could be used to predict the incidence of NSP and determine whether good physical fitness characters would be associated with lower NSP incidence in school-aged children at 2-year follow-up.
UNASSIGNED: After the invitation to nine schools, 970 children (10-15 years old) agreed to participate. Flexibility, fundamental movement skills, musculoskeletal fitness, and cardiorespiratory fitness measurements included in Finnish Schools on the Move! monitoring system for physical functional capacity were measured at baseline in 2013. The NSP incidence was assessed by an online survey during school hours after 1 and 2 years. Logistic regression was used to analyze associations between physical fitness characteristics and NSP incidence.
UNASSIGNED: The mean prevalence of NSP was 26% at baseline. The NSP incidence was 15% in the first and 18% in the second follow-up year. Good physical fitness was not associated with lower NSP incidence in the 2-year follow-up. Successful lower back extension (odds ratio [OR] = 2.83) and good scores in curl-up (OR = 1.80) adjusted with age, gender, and body mass index, were associated with higher NSP incidence between T0 and T2. Throwing-catching combination (OR = 0.55) was associated with a lower NSP incidence in unadjusted analysis, but the association did not remain after adjustments.
UNASSIGNED: Good physical fitness characteristics were not consistently associated with a lower NSP incidence in school-aged children in a 2-year follow-up. The role of general field-based physical fitness test as a screening tool for NSP incidence remains unconfirmed. More longitudinal studies are needed to detect the factors underlying NSP incidence in school-aged children.

Clinicians need to consider hepatoblastoma in the differential even in school-aged children or adolescents presenting with multiple liver tumors.

Nutrients are critical for optimal brain development, and good nutritional status is associated with cognitive development and improvement. The relationship between micronutrients intake and cognition in Ghanaian school-aged children has not been studied. The study investigated dietary intakes of micronutrients and cognition test performance of school-aged children. A cross-sectional study was undertaken among 438 school children, aged 9-13 years from ten randomly selected basic schools in Kumasi, Ghana. Socio-demographic data were obtained from a structured questionnaire. Dietary intakes of iron, zinc, vitamin B6, folate, vitamin B12, and vitamin A were determined from repeated 24-hr dietary recall data from 351 children, while cognition test was performed using a Raven\'s Coloured Progressive Matrices (RCPM), a 36-question test. Among 351 children, 156 (44.4%) had inadequate zinc intake, whereas 96 (27.4%) had inadequate iron intake. More than 1 in 2 children had inadequate vitamin A intake while 55.8% and 53.0% had inadequate vitamin B12 and folate intakes, respectively. More school-aged boys (66.3%) than girls (46.8%) had inadequate vitamin B12 intake (χ 2 = 13.393, p < .001), while for iron, folate, vitamin B6, zinc, and vitamin A, the differences were not significant. Mean RCPM test score differed significantly between school type (p < .001), but did not differ between the different ages, and between children with adequate and inadequate iron, zinc, vitamin B12, vitamin B6, and vitamin A intakes, except for folate intake (p = .050). Weak positive significant associations were observed between RCPM test score and zinc and folate intakes (p = .050). Dietary micronutrient intakes were inadequate in majority of these children, which put them at risk of weakened immune system and poor health, but did not show significant associations with RCPM performance. Further studies using other forms of cognition tests may help confirm our findings, and provide the impetus for the necessary interventions.
