Secular Trend in Portugal
This study of secular trend in Portugal has shown that a positive increment in height occurred in Portuguese 18year-old males between 1904 and 2000, and a secular trend in the age at menarche, towards an earliest age, also took place. Mean height increased 8.93 cm, from 1904 to 2000, when reached 172,13 cm. Besides that, in 2000, statistically significant differences (p ≤ 0.001) among the distr...
متن کاملAge at menarche and secular trend in Maharashtrian (Indian) girls
Age at menarche of 366 Maharashtrian Brahmin, Maratha and Scheduled Caste girls was studied and two hypotheses relating menarcheal age to physical growth were compared. Results indicated that both measurements, the height (the indicator of skeletal maturity), and the weight (the indicator of fat accumulation), were positively correlated with age at menarche. The well known phenomena of children...
متن کاملGrowth variation, final height and secular trend
Growth and body height have always been interesting topics in the public opinion. Particularly the stupendous increase of some 15 to 19 cm in final adult height during the last 150 years in most European countries (the “secular trend”), the concomitant changes in body and head proportions, the tendency towards early onset of sexual maturation, the changes in the age when final height is being r...
متن کاملImproving the determination of the gravity rate of change by combining superconducting with absolute gravimeter data
This paper evaluates different data-processing methods to determine the gravity rate of change, using repeated absolute gravimeter (AG) measurements and continuous monitoring by a superconducting gravimeter (SG). Based on synthetic data representative of signals observed by SGs at various station locations, we demonstrate that the addition of SG information mitigates the error in the estimation...
متن کاملAge at menarche and the evidence for a positive secular trend in urban South Africa.
Menarcheal age was estimated for 287 (188 Black; 99 White) urban South African girls born in Soweto-Johannesburg in 1990. The median menarcheal age for Blacks was 12.4 years (95% confidence interval (CI) 12.2, 12.6) and 12.5 years (95% CI 11.7, 13.3) for Whites. Data from six studies of menarcheal age, including the current study, were analyzed to examine the evidence for a secular trend betwee...
