Serum mineral and trace element concentrations in the Gidra of lowland Papua new Guinea
Serum concentrations of 11 elements (Na, Mg, P, S, K, Ca, Fe, Cu, Zn, Sr and Se) in the adult populations of the Gidra in lowland Papua New Guinea were measured. The marked characteristic of the element profile in the Gidra was higher Cu and slightly lower Zn concentrations than those in developed countries. Zinc nutriture of the Gidra was judged to be marginally deficient, presumably because of their high intake of crude fiber and Fe, which are …
Carbon and nitrogen isotopic characterization for Papua New Guinea foods
Stable carbon and nitrogen isotope ratios of the animal and plant food of the Gidra, who inhabit lowland Papua New Guinea and subsist mainly on hunting, gathering and horticulture, were measured to characterize the nutritional input of carbon and nitrogen of the Gidra. All the staple plant foods of the Gidra, such as sago and tuberous crops, were classified as C3 plants from their 13C/12C ratios (δ13C). The δ13C of the terrestrial mammals varied …
Dietary selenium intake of the Gidra, Papua New Guinea
Selenium (Se) concentrations in the food of the Gidra‐speaking people of Papua New Guinea were measured by fluorometry. Animal foods contained Se in larger concentrations than plant foods. Animal foods of aquatic origin contained more Se than those of terrestrial origin. Stepwise multiple regression analysis revealed an association between Se and the animal's mercury content. Se concentrations in rice and wheat flour, which were imported from out…

Compositional character of Papuan foods
In 78 food samples collected in the Papuan lowland, concentrations of major nutrients and trace elements (Na, Mg, A1, P, K, Ca, V, Cr, Mn, Fe, Ni, Cu, Zn, Sr, Cd, Hg, and Pb) were measured. Principal components analysis of local foods distinguished animal foods from plant foods: factor 1 had large positive loadings on protein, Na, P, Zn, and Hg contents and negative on carbohydrate content, and factor 2, positively on Mg, Ca, Mn, and Sr contents.…
Element intake of the Gidra in lowland Papua
Intake of 17 elements (Na, Mg, Al, P, K, Ca, V, Cr, Mn, Fe, Ni, Cu, Zn Sr, Cd, Hg and Pb) was estimated in four villages of the Gidra in lowland Papua New Guinea. Among these elements, inter‐village variation of intake was relatively large for Na, Al, V, Fe, Ni, Cd, Hg and Pb. The variation was attributed to the different concentrations in foods and drinking water, and the differences in food consumption by different villages. Compared to the int…
Grip strength and body composition of the Gidra Papuans in relation to ecological conditions
Maximum grip strength and body composition were measured in 136 Gidra-speaking adults in Papua New Guinea. The subjects inhabited two ecologically contrasting villages, one observing traditional ways of living and one influenced by modernization. Grip strength correlates with fat-free mass and body weight in all sex/village groups. Grip strength is greater in modernized villagers than in traditional villagers, but grip strength per unit body weig…
Salt consumption, body fatness and blood pressure of the Gidra in lowland Papua
The Gidra population in lowland Papua New Guinea, having lived as a no‐salt culture, is now subjected to modernization. In 1981, salt consumption, body fatness and blood pressures were measured for people in four ecologically different villages. Daily salt consumption of individuals was estimated from the sodium level per unit weight of creatinine in the morning urine and the daily urinary excretion of creatinine (estimation from fat free mass). …

Variation in elemental composition of Japanese ancient (Jomon and Yayoi eras) human bones
Excavated ribs obtained from 30 Jomon and 7 Yayoi sites, and 5 skeletal components (rib, hand phalanx, vertebra, skull and fibula) of 3 different skeletons were analyzed for concentration of 19 elements by ICP atomic emission spectrometry and atomic absorption spectrometry. Elements without showing locational variation in the concentration were B, Ca, Cu, Ni and Pb, and large variations were for Al, Co, Fe, Sr, Ti and V. Between two eras, signifi…
An Analysis of Relationships between Menarche and Attained Body Size
The extent of contribution of body weight, height and age to the attainment at menarche was evaluated in a sample of 275 Japanese girls. The means of age, height and weight at menarche were 12.5 SD 0.89 years, 151.1 SD 5.73cm and 42.3 SD 5.75kg, respectively. According to the bivariate correlation analysis between age and height, and age and weight at menarche, height increased (r=0.406, slope=2.603) while weight did not increase significantly wi…
Diversity and change of food consumption and nutrient intake among the Gidra in Lowland Papua
Food consumption and nutrient intake of the Gidra in lowland Papua, who number 1,850 and inhabit 13 villages, were analyzed by compilation of five two‐week (or twelve‐day) records, in a single village in 1971 and in four different villages (including the above village) in 1981. The nutrient intake of the Gidra varied both over time and among the villages. Difference in food consumption patterns included different proportions of plant staples such…
Composition of local and purchased foods consumed by the Gidra in Lowland Papua
Seventy‐eight foods (70 locally exploited and 8 purchased) consumed by the Gidra in lowland Papua were sampled and their nutrient compositions and metal concentrations were determined. Because local food samples were collected in the state in which they were normally eaten by the villagers, the water content of several of our samples, especially of sago flour, was much greater than that in the literature. The variation of protein and energy conte…
Mortality of an urban population by period of residence in a rapidly industrialized city
Mortality differentials among urban residents who were classified by period of residence in a rapidly industrialized city were analysed for those aged 20 and over dying between April 1974 and March 1978. The highest mortality in the male population appeared in the group with under 5 years of residence, and this was attributed to the high age-specific death rates at age 50 and over. In females, a mortality excess conspicuous in those under age 50 …
Physical Characteristics of Okinawan Diving-Fishers in Relation to Work History
Thirteen anthropometric and physiological measurements of 84 male diving-fishers in Ishigaki City, Okinawa Prefecture were conducted. The first comparison was between the present data and the corresponding data of six other groups of Japanese muscular workers, and the second focused upon the differences within the Ishigaki diving-fishers in relation to their work history. The Ishigaki diving-fishers were characterized by larger biceps circumferen…
Age differences in Principal Component Analysis for Physique and Body Build Indices of School Children

The loading patterns of component I indicating body size started to change at the time corresponding to adolescent growth spurt. Rohrer index, Livi index, p…
Age at Menarche of Japanese and Bolivian Girls in a Pioneer Community of Eastern Lowland of Bolivia
The age at menarche of both Japanese and Bolivians living in a colony of Japanese immigrants in eastern Bolivia was examined. Maximum likelihood estimation gave mean menarcheal ages of 13, 15±1.08 for Japanese girls and of 13.08±0.89 for Bolivian girls. The girls are further classified according to the fathers' occupation (Japanese-Agriculturist I, Agriculturist II, Non-Agriculturist: Bolivian-Self-Employed, Employed, Unknown), and the age at men…
Mineral contents in hair from Oriomo Papuans and Akita dwellers
Mineral (Na, K, Ca, Mg and Zn) contents in the hair from two populations, Oriomo Papuans and Akita in Japan, which have different salt intake, were investigated. Determination of minerals was conducted on untreated hair samples and hair samples washed with distilled water or ten percent acetic acid solution. The sodium content of the hair of persons living in Akita whose salt intake was in excess of 20 g/day was significantly greater than that of…
Changing food consumption of Japanese immigrants in the lowland of Bolivia
Dietary records (a three‐day period in July and August, 1975) of 34 households of Japanese immigrants in the lowland of Bolivia were analyzed for the amounts and types of food consumed. The objective of the study was to determine the food habits of immigrants during the various stages of their resettlement and socio‐economic development. The results were as follows: The number of foodstuffs exceeded 100, among which rice was staple through all th…
Indices of Body Build in Children
For revealing the character of various indices of body build in children, variable sets of seven anthropometric measurements and eight indices for 474 boys and girls 7-18 years in age inhabiting Nase City were investigated with principal components analysis. With a negligible difference by sex, three components accounting for over 90% of total variance were extracted, which was interpreted to indicate respectively body size, body build and skinfo…
Zinc, copper and mercury in Oriomo Papuans' hair
Hair samples from the Oriomo Papuans, being sago‐ and meat‐eaters, were analysed for zinc, copper, and inorganic and organic mercury concentrations. Values obtained were compared between the sexes, and with those for Japanese islanders (rice‐ and fish‐eaters) on Kuchinoshima in the south of Japanese mainlands. Hair zinc values of female Papuans were significantly lower than those of male Papuans and adult male and female Japanese islanders, but n…
Hair mercury value and fish‐eating habit
Mercury levels in the hair segment close to the scalp were well correlated with fish‐eating habits for residents on a small island in the south of Japanese mainlands. Mercury levels changed in segmented hair samples along with the distance from the scalp. The time of sprouting of hair segment in which the mercury level showed the peak coincided well with the peak of catch of fish on the island
