Abstract
This study tried to clear the characteristics of height growth pattern depending on Peak Height Velocity age in early, average and Late groups. And in it, height growth tendency of girl students in age 7 to 18 rears old was compared and investigated in order to know influencing factors, menarcheal age relation. The samples were senior girl students at high school in Seoul. Longitudinal data and survey data were collected in August, 1990. The results could be summarized as follows: 1. On distance curve, the height growth line in early group tended to be the highest and in late group the lowest. On the other hand, on velocity curve late group showed the highest peak and early group showed the lowest peak. In late group, velocity curve was too steep. Of course, these early, average and late groups were classified by PHV age. 2. In these three groups, late group showed the most growth amount per year. However, on distance curve, early group showed higher line than late group. Perhaps this means that peak growth amount in late group might have an effect on mean. 3. Growth amount of adolescence spurt age in these three groups was 6.96cm at age 9(early group), 7.27cm at 11(average group)and 7.65cm at 13(late group). In early group, because PHV age came too early, it was difficult to find exact adolescence spurt period. In early group, the adolescence spurt period is considered to come at about age 7 to 9. In average group, at 9 to 11 and at 12 to 13 in late group. Especially, spurt of late group was remarkable. 4. When the grouth amount of PA, before PA and after PA was compared, growth amount of PA in all three groups was about 20%. In early group, growth amount of APV tended to be large and in late group, that of APV tended to be large and in late group, that of BPV was large. In average group, growth amount of BPV was larger than that of APV. 5. For the purpose of comparing total height growth amount of these groups at age 18, the height growth was assumed to be over. And then, the difference of three groups was studied but it's not significant. 6. Although the difference between height growth and family environment, dietary habits, exercise, disease history in these three groups was Investigated, only the income was significant. The significance of all the other factors was not approved. 7. When menarcheal age was compared with PA, generally we know menarche appeared after 1∼2 years of PHV age. But in case of early group, the difference between PHV age and menarcheal age was 5.34 years. In average group, 2.45 years and 0.82 years in late group.;本 硏究는 女學生의 身長發育을 分析하기 위하여 縱斷的 資料를 利用하여 多樣한 個人의 發育速度曲線을 最大發育速度의 發現時期에 따라서 早熟群, 普通群, 慢熟群으로 분류하여 이들의 身長發育 Pattern의 特徵을 밝히는 것을 目的으로 하며 影響을 미칠 것으로 예상되는 家庭環境狀態, 營養狀態, 運動狀況, 病歷狀況과의 關係, 初經年齡과 身長의 最大發育速度의 發現時期와의 關係를 알아보기 위하여 시도하였다. 이에 本 硏究는 서울市內 一部 人文系 女高生 923名을 對象으로 7歲에서 18歲까지의 身長의 縱斷的 資料를 이용하여 分析하였다. 硏究의 結果는 다음과 같다. 1. 早熟, 普通, 慢熟群의 身長發育 pattern은 發育曲線에 있어서는 早熟群이 全年齡層에서 身長이 켰으며 發育速度曲線에있어서는 慢熟群의 Peak Age때의 發育量이 가장 많으며 경사진 曲線을 보인 반면 早熟과 普通群에서는 대체적으로 완만한 曲線을 나타내었다. 2. 身長의 年間發育量에 대한 比較에서는 慢熟群이 가장 많은 發育量을 보였으며 통계적으로도 有意한 것으로 나타났다.(P<0.001) 3. 思春期 spurt時期의 發育量에 대한 比較에서는 早熟群의 경우 9歲에 6.8cm, 普通群인 경우 11歲에 7.27cm, 慢熟群의 경우 13歲에 7.65cm로 思春期 spurt시기의 發育量은 慢熟群이 가장 많은 것으로 나타났으며 spurt 持續期間은 早熟群의 경우 7歲∼9歲, 普通群의 경우 9歲∼11歲, 慢熟群의 경우 12歲∼13歲로 思春期 spurt는 慢熟群에서 현저하였다. 4. 身長에 대한 比較로 18歲때의 成長을 發育이 停止한 것으로 간주하여 3群間 差異를 比較하였으나 3群間의 有意한 差는 없는 것으로 나타났다. 5. Peak Velocity와 Peak Age以前, Peak Age以後의 發育量을 比較하였을 때 3群의 Peak velocity는 全發育量의 약 20%를 나타내 Peak Age時의 發育量이 많은 傾向이었으며 慢熟群에서는 Peak Age以前의 發育量이, 早熟群에서는 Peak Age以後의 發育量이 많은 것으로 나타났다. 6. 家庭環境狀態, 營養狀態, 運動狀況, 病歷狀況에 따른 差異에 대해서는 家庭月收入에 대해서만 有意差가 있었으며(P<0.01) 그외에는 有意差가 없는 것으로 나타났다. 7. 初經年齡과 PHV(Peak Height Velocity)年齡의 關係를 比較한 結果, 早熟群에서는 그 差가 5.34年, 普通群의 경우 2.45年, 慢熟群의 경우 0.82年으로 各各 다르게 나타났다.
