—Especially about Analysis of Skinf old Thickness—Isami MORI1972 Volume 38 Issue 5 Pages 193-209
Published: 1972
Released on J-STAGE: June 28, 2010
JOURNAL FREE ACCESSSince skinfold thickness measurement was considered the most valid method for obesity screening, it was performed at primary schools in Shizuoka Prefecture during 4 years (1968-1971) The results are summarized as follows : (1) Almost similar values were obtained with calipers of different types as Eiken-and Keys-type. (2) Skinfold thickness values became larger with age, and girls>boys was observed in every age. (3) Through comparison with 3 sites (upper arm, back and abdomen) measured, upper arm>abdomen>back was observed in almost all children except lower school grade boys. It seems more desirable for obesity screening to measure upper arm and abdomen. (4) Skinfolds of urban school children were thicker than of rural school children. (5) The correlations between skinfold thickness and several physique indices and IRSW were examined and risks of misjudgement with applying these methods were pointed out. Especially in case of Rohrer Index, the risk was biggest. (6) 3-6% of children were judged as slight obesity and 2-4, % as obesity. (7) A new index, which was expressed by skinfold thickness×IRSW, was proposed. This index named Mori Index, was considered well worth applying to obese children screening.View full abstractDownload PDF (1816K) -

JOURNAL FREE ACCESSFrom the data of Indian Vital Statistics in 1962-1964, the geographic distribution of sex ratio at birth and seasonal variation of the ratio in different states of India are studied. In the yearly average of these three years, higher sex ratios at birth distribute in the northwestern inland states than in the southern and eastern coast states. In Rajasthan and Uttar Pradesh the sex ratio is over 120 males to 100 females, which is higher than the highest ever known in Korea. The seasonal variation of sex ratio at birth in the northwestern inland states is more distinct than that in the southern and eastern coast states, as well as the seasonal variation of birth ratio. Both curves of the seasonal variation of sex ratio and of birth ratio have some phase difference, and the sex ratio is rather low in the months of higher birth ratio, and vice versa. Although Indian vital statistics is not yet satisfactorily established, peculiar geographic distribution and seasonal variation of the sex ratio, which seem to be influenced by climate, are perceived. To interprete the phenomena some hypotheses are adapted and discussed.View full abstractDownload PDF (1264K) -
II On Kasuga Village (pert 4) About the Myopia of the Peoples of the Elementary School and Junior High SchoolMakoto NAKAMURA, Kazuko GOTO, Sozaburo YOSHIHARA, Shuko YOSHIKAWA, Hid ...1972 Volume 38 Issue 5 Pages 223-232

JOURNAL FREE ACCESSThe peoples of the elementary school and junior high school with whom this investigation was made were the ones who the higher percentage of school myopia in 1971-1972. Compared to the whole country, the percentage of school myopia was about 3 times the average for the peoples of the elementary school and 1.5 for the peoples of the junior high school. The results of the investigation regarded the change in the power of seeing of the peoples after entering elementary school were as follows. There was a change in sixty percent of the peoples. It was evident that most of them gradually became worse in their seeing vision. The following are some of the reasons for becoming short-sighted. 1) The peoples of having too much food without a sufficient value of each nutritive elements (Cal., Protein, Fat, V.A, V.B1, V.B2, V.D) which should be ingested are apt to become short-sighted. 2) Most of the short-sighted peoples whose value for blood examination is less than the standard value. (blood examination; Hematocrit value, Hemoglobin concentration, Serum protein value) 3) Most of the short-sighted peoples have the some physical symtoms (commissural cheilitis, keratosis, abnormal patellar reflex). 4) There is no relation of cause and effect between relative weight and myopia. 5) It seems that there is not a certain relation of cause and effect between mothers' seeing vision and their peoples', but that they are gathered in their famillies which has the usually myopes. 6) Most of the peoples with good record at school are apt to have correct vision. 7) Most of the peoples who study at the room with low illuminance are apt to be short-sighted. But there is no relation of cause and effect between the illuminance of the room with a television set and myopia. 8) Most of the peoples who live in a room which there is little sun are apt to be short-sighted. 9) Most of the peoples who study for hours, or whose sleep is not enough are apt to be short-sighted. Considering the above items (No. 1-No. 9) in the view of statistics it is difficult to find a sufficient significance in them, but it is evident that they have made the reasons for many peoples' becoming short-sighted.View full abstractDownload PDF (1691K)
