Abstract
A longitudinal study has examined the growth of height, sitting height, body mass and triceps skinfolds in a sample of Inuit (281 boys and 266 girls) attending the Igloolik school between the years 1981 and 1989. Heights were around the 10th percentile of U.S. norms for 1970. A peak height velocity of 9.2 +/- 2.3 cm/year was reached by girls at 11.3 +/- 0.7 years, and in boys the peak rate of 8.6 +/- 3.7 cm/year was seen at 13.5 +/- 0.8 years. Sitting heights were also low relative to urban norms. Body mass approached the 50th percentile of U.S. norms, giving a large mass for height ratio at all ages. Triceps thicknesses for the girls were around the 10th percentile of urban norms, and in the boys began around the 25th percentile, but dropped steadily to the 5-10th percentile. No significant differences of growth patterns were seen between cohorts formed from students born in the years 1970/72, 1973/74 and 1975/76. However, comparison with earlier cross-sectional surveys in the same community showed a secular trend to greater stature and greater skinfold readings as the community had become acculturated to such features of modern living as mechanized transport and television. There were no systematic differences of growth rates between the summer and the winter seasons, and nutrition was good throughout. We thus conclude that the short stature has an inherited basis. Attention is drawn to the problem of interpreting curves of growth and weight for height in populations with an unusual body build.

Abstract
There was made a determination of the correlation relationships (CR) between indices of physical and sexual development (SD) of 1997 adolescents aged from 11 years 6 months to 17 years 5 months 29 days residing in the industrial center of the Southern Urals characterized by high levels of air pollution (API 7-13). Benzo(a)pyrene and formaldehyde contribute the greatest part to air pollution. The level of SD, time of appearance of secondary sexual characteristics was revealed to be interrelated with the pace of physical development of adolescents, regardless of the gender Children with an accelerated pace of physical development (macrosomatotype) are characterized by advancing sexual development and the earlier appearance of secondary sexual characteristics. Slow pace of physical development (microsomatotype) is characterized by SD retardation and the later appearance of secondary sexual characteristics. The degree of intensity of secondary sexual characteristics and such anthropometric indices as height, body mass are interrelated and have age and gender differences: the maximal CR for these indices is typical for boys aged from 13 to 16 years as for girls--of 13 and 14 years old.

Abstract
to ascertain if standard gestational age charts can be used to accurately predict the gestational age of fetuses of first-generation Oriental immigrants to Canada.
Over a 3-year period, all patients presenting for obstetric ultrasound examinations were invited to participate in the study. The authors recorded biparietal diameter, head circumference, femur length and abdominal circumference for 139 fetuses in the second and third trimesters. A study performed in the first trimester was used as the baseline for gestational age. The data for 126 of the fetuses were complete, and these data were used for the analysis.
For 77 of the fetuses, both parents were Oriental, and for 49, one or both parents were not Oriental; the latter constituted the control group. A total of 1008 individual measurements were obtained, and of these, all but 14 fell within two standard deviations of the norm, according to standard gestational age charts. Of the abnormal measurements, seven were obtained from five fetuses with Oriental parents, and seven were obtained from six fetuses in the control group. The difference between the two groups in the proportion of measurements falling either above or below two standard deviations from the norm was not statistically significant (Fisher's exact test, p = 0.41694).
The authors conclude that standard gestational age charts can be used to determine gestational age in first-generation Oriental immigrants to Canada.
