“…In attempting to assess the effects of female malnutrition on physical work capacity, considerable extrapolation must be done from studies of males, since surprisingly little research has been done on women. The long-term effects of childhood malnutrition, acting through short stature and reduced muscle mass, have a reasonably clear negative effect on the productivity of men engaged in strenuous activities such as cutting cane or moving earth [64]. In addition, deficiencies of several micronutrients, particularly iron, but also vitamin C and the B-complex vitamins, have been found to have a negative effect on physical work capacity [46].…”

This article reviews existing data concerning the causes and consequences of female malnutrition in sub-Saharan Africa. As in most parts of the world, the primary cause of female malnutrition is household food insecurity compounded by low household and individual incomes. Gender-specific factors that further undermine women's nutritional status are the severe physiological burden of frequent child-bearing and the continuous long hours of energy-intensive work. Negative consequences of malnutrition among females include high rates of mortality and morbidity, impaired learning, low birthweights, and reduced energy for discretionary activities. We question the conclusion of other studies that African women have developed special “adaptive mechanisms” to compensate for nutritional deprivation, and recommend that further research investigate the hidden individual and societal costs of malnutrition among women.

“…Moreover, the total effect of height on ln( w) now depends on a1 and a,, and the relative effect of W and H on ln(w) depends on estimated parameters (equation 5). This distinction is important, as height may not be a productivity-limiting factor for light to moderate activities, but may be a limiting factor for strenuous activities (Martorell and Arroyave, 1988;Payne and Lipton, 1990).…”

“…Linkages between adult body size, physical work capacity (VO 2 max), and malnutrition were proposed more generally by Spurr (1988), and in ways in which these relationships might influence the nutritional state of the household, especially the nutritional status of younger children, was modeled by Martorell and Arroyave (1988) (Fig. 1).…”

Maternal work and childhood nutritional status among the Purari, Papua New Guinea

In traditional economies, body size, physical work capacity, subsistence productivity, and nutrition of adults may be interrelated, and one cross-generational effect of these relationships may operate through the household, influencing nutritional status of children. In this analysis, the relationships among adult body size, work productivity in terms of time spent making sago starch, dietary diversity, nutrient availability, and childhood nutritional status are examined in the Purari population of Papua New Guinea, a group largely dependent on the starchy staple palm sago, which is devoid of all nutrients apart from energy. Observations of work scheduling, household food and nutrient availability, and nutritional status were carried out for 16 women, their households, and their children. A multiple regression model of hours spent in sago making on a particular day with days spent in other subsistence activities showed a negative relationship with the number of days spent in sago-making and a positive relationship with the number of days spent fishing. The number of hours spent in sago-making on a particular day was also positively related to daily per capita availability of protein at the household level. This is not a function of maternal nutritional status, however, since there is no association between body size of adult females and the number of hours spent making sago on a particular day. Nor does the greater per capita protein availability at the household level in households where women spend longer on a particular day in sago-making result in improved childhood nutritional status. Since relationships among adult body size, work productivity, dietary diversity, nutrient availability, and childhood nutritional status are only partially demonstrated in this population, it may be that these linkages may only be important if physically arduous work is needed more consistently than is the case in the Purari delta.
