In many lowland areas of Papua New Guinea, rainfall and subsistence agriculture show marked seasonal patterns. As part of an intensive study of the relationship between subsistence agriculture and nutrition in one lowlands community where there is a high rate of child malnutrition, an attempt was made to determine whether the seasonality of the agricultural system is an important influence upon nutritional status. Between October, 1980, and September, 1981, rainfall and temperature records were kept, the agricultural year described and a sample of adults weighed monthly. The analysis detected statistically significant weight changes for both males and females. The description of the agricultural year provides a reasonable explanation for the pattern of weight change observed. However, the range in mean monthly weights is small, and the biological significance difficult to determine. It is unlikely that seasonality alone is sufficient to account for the high rates of malnutrition.read more

Acculturation and health in the Highlands of Papua New Guinea: dissent on diversity, diets, and development.
Dennett G,Connell J +1 more
TL;DR: An examination of data from the Central Highlands of New Guinea questions a widespread tradition in human ecology claiming that unacculturated peoples were healthy adequately nourished and living in harmony with their environments before acculturation reduced their health and nutritional status by disrupting the ecological principles through which homeostasis was achieved.

Social and public health issues in adaptation to low energy intakes.
TL;DR: The evidence of adaptation to low energy intakes in real-life conditions is reviewed and it is shown that the currently available evidence does not support the recourse to this behavioral strategy in developing countries undergoing recurrent seasonal energy stresses.
Food and nutrition insecurity in northern Benin : impact on growth performance of children and on year to year nutritional status of adults
TL;DR: It is suggested that the growth of children is substantially depressed by the seasonal food shortage, and the stress on energy balance created by an unimodal climate may result in a modest weight change and does not necessarily result in metabolic or behavioural adaptation.

The assessment of the nutritional status of the community
TL;DR: In this paper, a monograph delineates the magnitude and geographic distribution of malnutrition as a public health problem and the ecological factors contributing to malnutrition are explained and analyzed and corrective measures e.g. sanitary water are suggested.
