目的巴布亚新几内亚高地的人们以红薯为主食，动物蛋白的摄入量有限。在这种蛋白质摄入量微乎其微的社会中，按性别或年龄在家庭内部分配动物蛋白质是很重要的。本研究的目的是探讨在巴布亚新几内亚高地，富含蛋白质食物的性别和年龄分布模式与经济发展之间的关系。方法对1995年在两个地区(塔里和塔里移民居住的国家首府)采集的指甲和2007年、2012年和2013年在三个不同经济发展程度地区(莱瓦尼、塔里和戈罗卡)采集的头发的碳、氮同位素组成进行了分析。结果指甲样本分析表明，农村社区的δ15N低于城市移民社区，δ-15N存在性别差异(男性高于女性)，而后者无性别差异。年龄与δ15N或δ13C值均无相关性。对头皮毛发样本的分析表明，最不发达地区莱瓦尼的δ15N值最低。此外，莱瓦尼的δ15N值存在显著的性别差异，而塔里岛和戈罗卡岛的性别差异不显著。年龄与δ15N或δ13C值均无关联。讨论随着巴布亚新几内亚高地社区的经济发展，动物蛋白消费中的性别不平等似乎有所减少。Am J Phys Anthropol159：164-173,2016。©2015 Wiley期刊，Inc.
ObjectivesPeople in the Papua New Guinea Highlands consume sweet potatoes as their dietary staple; consumption of animal protein is limited. In such societies with marginal protein intake, the intra‐household allocation of animal protein in terms of sex or age is of importance. The objective of this study was to investigate how the allocation pattern of protein‐rich foods by sex and age is associated with economic development in the Papua New Guinea Highlands.MethodsThe carbon and nitrogen isotopic compositions of fingernails, collected in 1995 in two areas (Tari and Port Moresby [the national capital where Tari migrants resided]), and of scalp hair, collected in 2007, 2012, and 2013 in three areas of different degree of economic development (Levani, Tari, and Goroka) were analyzed.ResultsAnalysis of fingernail samples showed that δ15N was lower in rural communities than in the urban migrant community, while a sex difference in δ15N (higher in males than in females) was found in the former but not in the latter community. Age was not associated with either δ15N or δ13C values. The analysis of scalp hair samples showed that δ15N values were lowest in Levani, the least developed area. Furthermore, there were statistically significant sex differences in δ15N values in Levani but not in Tari and Goroka. Age was not associated with either δ15N or δ13C values.DiscussionThe sex inequality in animal protein consumption seems to have decreased as the communities in the Papua New Guinea Highlands have experienced economic development.
