Respiratory function in aboriginal school children.

Two hundred and three school-age Aboriginal children living on Cherbourg Aboriginal Settlement have had lung function tested with a dry spirometer. As with other non-Caucasian children, the forced vital capacity (FVC) was about 25% below values for Caucasian children, but the ratio between forced expiratory volume in one second and forced vital capacity (FEV1/FVC ratio), the mean mid-expiratory flow rate (MMEFR) and testing before and after a bronchodilator showed no evidence of widespread airways disease. Analysis of a subgroup of 126 children showed that birthweight, weight at one year of age, and current nutrition did not affect the level of the FVC.

Intellectual and functional status at school entry of children who weighed 1000 grams or less at birth: a regional perspective of births in the 1980s.

The intellectual and functional status of a regional cohort of children who weighed 501 to 1000 gm when born between 1980 and 1982 was evaluated at a mean age of 5 1/2 years by standard psychometric tests. Of 90 long-term survivors (survival rate 49%), 78 children (87%) had the full test battery, 5 children (6%) had other tests (4 were blind), and one child was untestable. Most of the mean scores were within 1 SD of the test norms; the lowest scores were in the McCarthy Motor scale and in the Beery Test of Visual-Motor Integration. Children without neurologic impairments and those with an IQ greater than or equal to 68 (n = 60) had higher overall scores but still performed poorly on the Motor subscale and the Beery test. Children who weighed less than 800 gm at birth (n = 28) were similar to those who weighed greater than 800 gm (n = 50), except in the Memory and Motor subscales, in which they performed significantly less well. At a functional level, determined by the Vineland Adaptive Behaviour Scales, two thirds of the children were performing in the adequate range and the remainder in the moderately low to low range. Of the 43 children with no neurosensory impairments and an IQ greater than or equal to 84, 49% were identified (by the Florida Kindergarten Screening Battery) to be at mild to high risk for future learning disabilities. The data from this unselected population provide an unbiased estimate of the prevalence of intellectual and functional problems in children who weighed less than or equal to 1000 gm at birth.

Lung function in school-age children who had mild lower respiratory illnesses in early childhood.

We examined the relationship between patterns of mild lower respiratory illness (LRI) experienced in early childhood and lung function in 89 boys and 70 girls 6 to 18 yr of age. The children's histories of outpatient visits for wheezing and nonwheezing LRI during the first 6 yr of life had been documented by physicians in a single pediatric practice. Most children were reported by their parents to have been free of recurrent respiratory symptoms during the 2 yr prior to lung function testing. In sex-specific analyses, average lung function assessed by spirometry was similar in children who had made zero or one physician visit for wheezing LRI during the preschool years. Boys who had experienced two or more episodes of wheezing LRI during the preschool years had lower average FEV1, FEV1/FVC, FEF25-75, Vmax50, and Vmax75 than did boys who had zero or one preschool wheezing illness. The association between recurrent preschool wheezing LRI and later lung function remained after exclusion of data from seven boys who were reported to have wheezed in the 2 yr prior to study. Girls who had experienced two or more preschool wheezing LRI had lower average FEF25-75 and Vmax50 than girls with a history of zero or one such illness, but differences were not statistically significant. Recurrent nonwheezing LRI during the preschool years was not significantly associated with subsequent lung function in either sex, regardless of preschool wheezing LRI history. Detailed information concerning early childhood LRI experience is valuable in epidemiologic studies of factors influencing lung function in children.

[Use of some biochemical and physico-chemical indices for the evaluation of lung function in healthy school-age children].

The biochemical and physicochemical characteristics of nonrespiratory pulmonary functions were determined in 255 children of school age according to the condensate of exhaled air. As compared to the younger children, those belonging to the senior age groups manifested an increase of specific respiratory moisture loss. As compared to winter, specific respiratory moisture loss in summer was found to be decreased; the condensate of exhaled air was discovered to have a higher content of total protein, elevated concentration of surface active substances in the lung surfactant, and to show a certain tendency towards reduction of the intensity of the processes of free radical oxidation. No sex-associated differences were established between the characteristics under study.

Pulmonary function studies in healthy school boys of West Bengal.

The establishment of normal standards of dynamic pulmonary function measurements in the form of prediction equations will serve as a remedial measure of different aspects of obstructive pulmonary diseases, especially in children. With a view to achieving the target, dynamic pulmonary function measurements were undertaken on 328 healthy school-going children of West Bengal having age ranging between 9 and 18 years. All the spirometric measurements except PEFR were taken with the help of a 9 l closed-circuit type expirograph following the methods and techniques of American Thoracic Society. PEFR was measured by Wright Peak Flow Meter. Prediction equations were derived on the basis of age and height for all the pulmonary function measurements except FEV1% and FET. The prediction equations for FVC, FEV1, MVVF, and PEFR were reliable, but relative variability of predicted FEF25-75% and FEF75-85% was very large. A comparative study of FVC, FEV1, and PEFR values of our subjects, standardized for age and height, was much closer to the boys of Delhi in FVC but higher than South Indian boys in FEV1, North and South Indian boys in PEFR. In an attempt to compare FVC and FEV1 values of our subjects with foreign populations, it is revealed that boys of our study were much lower than American (White), European, and Jordanian boys but comparable with those of Chinese and Libyan boys.

School counseling and positive mental health: when does 1 + 1 = 3?

School counseling and guidance services are specifically intended to develop and maintain positive mental health among students. Although some school counselors have been highly effective, the majority have been only moderately effective because of the difficulties they have encountered in this mission. Personal, academic, and vocational counseling and information processing from either remedial or preventative perspectives are currently the most common functions within school counseling services. The factors limiting the effectiveness of these and other school counseling functions include discrepancies between school counseling training and practice, school counselor professional isolationism, lack of understanding of school counseling roles and functions, and the poor professional attitudes of some school counselors. As the school counseling profession develops, these inhibiting factors should be overcome as a result of changes in school counselor roles and activities and associated changes in school counseling and guidance services.
