Purpose: The aim of the paper was to study the prevalence of myopia, hyperopia and astigmatism in schoolchildren ranging from 6-18 years of age.
Material And Methods: 5724 children from elementary schools, junior high schools and high schools were examined (2765 boys and 2959 girls, aged 6-18 years, mean age 11.7, SD = 3.2). The examined students were Caucasian and resided in and around Szczecin, Poland. The examination included retinoscopy under cycloplegia. The refractive error readings were expressed as the spherical equivalent (SE). Myopia was defined as SE of at least -0.5 D, hyperopia as SE of at least +1.0 D. Astigmatism was diagnosed when the difference in the refraction of axes in one eye was greater than 0.5 DC. The statistical analysis of data was performed by calculating the linear correlation coefficients and the coefficients for the regression equation. Additionally, Spearman's rank correlation coefficient was calculated. P values of less than 0.05 were considered statistically significant.
Results: It was observed that 13% of Polish students in the age group from 6 to 18 were myopic, 38% of students were hyperopic and 4% were astigmatic. Besides, a positive correlation was found between the prevalence of myopia and age (p <0.001) as well as a negative correlation between prevalence of hyperopia and age (p < 0.001). An association between the prevalence of astigmatism and age was not observed.

Objectives: Lymphatic filariasis (LF) elimination efforts in Ghana have been ongoing since 2001, achieving substantial progress through mass drug administration (MDA). However, despite significant advances, LF transmission persists in certain areas. Some districts previously classified as non-endemic have reported lymphedema and hydrocele cases, raising concerns about LF endemicity.

Unlabelled: The purpose of this study was to assess the methodology for selecting sports talent in the Chilean Promising Athletes Program (CPAP).
Methods: The standing broad jump (SBJ), medicine ball chest throw (MBCT), thirty-meter running sprint (RS-30), Agility-T (T-test), and height were analyzed in 3060 schoolchildren from Chile, grouped by sex, age, geographical area (north, central and south) and maturity status at peak height velocity (PHV) in pre-, circa- and post-PHV.
Results: Superior differences were found in boys for all age ranges in SBJ, RS-30, T-test, and MBCT ( < 0.
Dietary diversity and its associated factors among school children in conflict affected communities of southern Ethiopia.

School of Public Health, College of Health Science and Medicine, Wolaita Sodo University, Sodo, Ethiopia.
Background: Globally, more than 815 million estimated people worldwide suffer from malnutrition or are unable to access enough food due to malnutrition. Conflict remains the single most fundamental factor contributing to chronic malnutrition in the conflict-affected areas. Developing a healthy and balanced dietary pattern is essential for school children because their habits in this period may last longer.

Aim: This prospective clinical study aimed to clinically investigate the efficiency of (GIC) glass-ionomer cement application (Ionostar Plus + Easy Glaze, VOCO) in reducing hypersensitivity in permanent molars affected by molar incisor hypomineralisation when assessed immediately (15 min) and 12 weeks after its application.
Materials And Methods: Children with at least one hypersensitive MIH-affected permanent molar (MIH-TNI-3 or 4). The pre-treatment status was evaluated and only included if they did not receive a tooth-specific in-office desensitizing treatment within one month.
