INTRODUCTION: Studies investigating the lung function of school-age obese asthmatics are rare. The purpose of this study was to compare lung functions in school-age obese asthmatics with non-obese asthmatics. METHODS: Ninety-two children were assigned to obese asthmatics (OA group, n=43) and non-obese asthmatics (A group, n=49) groups. A baseline impulse oscillometry test was performed to measure lung functions. RESULTS: Baseline percent predicted value of R20 (p=0.025), R5-20 (p=0.040), and Fres (p=0.018) were significantly increased in obese asthmatics than non-obese asthmatics. AX was also higher in obese asthmatics compared to non-obese asthmatics, however, the difference was insignificant (p=0.787). Percent predicted value of R5 (p=0.007) and R10 (p=0.017) were higher in atopic than non-atopic obese asthmatics. Percent predicted value of R5 was higher in exercise-intolerant than exercise-tolerant non-obese asthmatics (p=0.045). Additionally, R10 was higher in non-obese asthmatics with household mold exposure than that without household mold exposure (p=0.045). The z scores of BMI or weight were correlated with none of the IOS parameters (p>0.05). DISCUSSION AND CONCLUSION: Main bronchial and peripheral airway resistance were higher in school-age obese asthmatics compared to non-obese asthmatics. Peripheral airway resistance was higher in atopic obese asthmatics as well as in exercise intolerant asthmatic children and those with household mold exposure.

BackgroundDaily levels of ambient air pollution and pollen may affect lung function but have rarely been studied together. We investigated short-term exposure to pollen and air pollution in relation to lung function in school-age children from a French population-based birth cohort.MethodsThis study included 1063 children from the PARIS (Pollution and Asthma Risk: an Infant Study) cohort whose lung function and FeNO measurements were performed at age 8 years old. Exposure data were collected up to 4 days before testing. We estimated daily total pollen concentration, daily allergenic risk indices for nine pollen taxa, as well as daily concentrations of three air pollutants (particulate matter less than 10 µm (PM10), nitrogen dioxide (NO2), ozone (O3)). Children with similar pollen and air pollution exposure were grouped using multidimensional longitudinal cluster analysis. Associations between clusters of pollen and air pollution exposure and respiratory indices (FEV1, FVC, FeNO) were studied using multivariable linear and logistic regression models adjusted for potential confounders.ResultsFour clusters of exposure were identified: no pollen and low air pollution (Cluster 1), grass pollen (Cluster 2), PM10 (Cluster 3) and birch/plane-tree pollen with high total pollen count (Cluster 4). Compared with children in Cluster 1, children in Cluster 2 had significantly lower FEV1 and FVC levels, and children from Cluster 3 had higher FeNO levels. For FEV1 and FVC, the associations appeared stronger in children with current asthma. Additional analysis suggested a joint effect of grass pollen and air pollution on lung function.ConclusionDaily ambient chemical and biological air quality could adversely influence lung function in children.

Background. Knowledge regarding the relationship between writing kinetics and the difference among writing tasks is limited. Purpose. This study examined the differences in handwriting performance when doing tasks with different levels of challenge from both temporal and kinetic perspectives among children in four different age groups. Method. The cross-sectional design introduced a force-acquisition pen to detect differences of pen grip and writing kinetics among 170 school-age children doing writing tasks at different difficulty levels. Data were obtained on the force information of the digits and pen tip and the kinetic parameters to examine the coordination-and-control mechanism between the digits and pen. Statistical analyzes were carried out to indicate the differences in writing performance among groups and tasks. Findings. Statistical differences in the pen-grip forces, force fluctuation, and force ratio between grip and pen-tip forces were found when performing different writing tasks and among different age groups. Implications. The study provides an alternative method to explore how writing performance among school-age children can vary according to the difficulty of the writing tasks.

Equilibrium represents the motor capability responsible for the performance of virtually all functional movements. Thus, the importance of early diagnosis of equilibrium levels in boys and girls was recognized as the key factor for the prevention of motor deficits and muscles misbalances later in life. Purpose: The purpose of this paper was to show the difference between boys and girls aged 7‒10 years in the level of unilateral static balance of the take-off leg. Methods: Research was conducted at the Kvarner Athletics Club Rijeka, and it involved 80 children aged 7‒10 years (38 boys and 42 girls). Measurement of static unilateral equilibrium was obtained using Gyko Inertial System (Microgate, Bolzano, Italy). Three attempts were made in 20 seconds and two motor variables were observed: medio-lateral and antero-posterior trajectories of the body. For both variables, the arithmetic mean, the minimum and maximum score and standard deviation were calculated. Moreover, a non-parametric method of the Mann-Whitney U test was used to determine statistical significance between boys and girls. Statistical significance was set at p < 0.05. Results: Statistically, girls have significantly better results compared to boys, both in the medio-lateral trajectory variable (M_Sumg = 335.1, M_Sumb = 479.34) and the antero-posterior trajectory variable (M_Sumg = 291.14, M_Sumb = 411.71). Conclusion: The results of this study showed that girls aged 7‒10 years achieved significantly better results compared to boys in observed motor variables (medio-lateral and antero-posterior trajectory of the body), when performing a static unilateral take-off leg balance test. These results are consistent with previous research. Indications for such results stem from different perspectives, among which the most common one refers to the earlier maturation of the systems responsible for postural control in female bodies. Recommendation for further research is to conduct examination on a larger sample of subjects, in younger children (pre-school age) and with both legs.

The Difference

Objectives. To explore the role of internal astigmatism (IA) in the growth of axial length (AL) in school-age children. Methods. Total astigmatism (TA), corneal astigmatism (CA), and AL of all children in Jing’an District 2nd Centre Primary School in Shanghai were measured. In IA, the difference between TA and CA was also calculated using vector analysis. The association of axial length with IA, genders, and age was analyzed using linear regression. The difference of IA between both eyes was also calculated. The AL between both eyes was compared using paired samples t-test when DIA = 0 D, <0.5 D, and ≥0.5 D. Results. Six hundred and twelve cases (98.23%) in 623 children aged 7–12 yrs older entered into the study. Genders, age, and IA all affected AL. This could be represented by a linear regression line in the form AL = 21.46 − 0.43∗gender + 0.22∗age + 0.46∗IA (male = 1, female = 2; t=7.01, P<0.01 for sex; t=11.6, P<0.01 for age; and t=6.6, P<0.01 for IA; R2=0.16). The AL in the eye with larger IA was also longer when DIA was larger than 0.5 D (t=2.65, P<0.01). Conclusions. IA was observed to be associated with AL and might be a risk factor of the onset and progress of myopia in school-age children.
