Peak Height Velocity Maturity Offset Estimated From Cross-sectional Vs. Longitudinal Growth Data

Longitudinal Vs. Cross-sectional Analysis

The survey literature distinguishes cross-sectional and longitudinal designs, but most surveys conducted in practice are based on cross-sectional designs. The limitations of these cross sectional surveys are that they are confined to a specific point in time. That is, they provide us with a snapshot of a sample of a population at a single point in time. Since population characteristics constant...

Pubertal Gynecomastia Coincides with Peak Height Velocity

OBJECTIVE Pubertal gynecomastia (PG) occurs in up to 65% of adolescent boys. In this study, we investigated the relationship between the ages at which PG and peak height velocity occur in pubertal boys. METHODS This was a prospective study that was designed to detect PG within three months of its emergence. We examined one hundred and six boys who were followed for short stature and/or delaye...

Estimated height and peak runoff rate in a stream erosion in Kojoor region Nowshahr – North Alborz

Flooding is a natural hazard events and Survey data from the annual losses due to flood in Iran and the world show the extent of the flood damage caused on natural and human resources. To estimate height of the runoff and discharge maximum in basins and stream erosion, there are various experimental methods and mathematical models that one of these models, SCS model is. Thus, the aim of this st...

Geographical Differences in the Population-Based Cross-Sectional Growth Curve and Age at Peak Height Velocity with respect to the Prevalence Rate of Overweight in Japanese Children

The School Health Examination Survey is a nationwide examination carried out annually in Japan, and the results are entered into a prefectural-level physical measurement database. We used this database to determine the geographical differences in a population-based cross-sectional growth curve and investigated the association between age at peak height velocity (PHV) and the prevalence rate of ...
