Maternal skills and efficiency
To optimize her own or her family's welfare, a woman must manage the resources under her control efficiently. (Lack of control over many resources contributes to women's low productivity and adverse outcomes, but that is discussed later.) Some families are more successful than others in producing wellnourished children under poverty conditions [101; 102]. Many studies show that maternal literacy and schooling are associated with improved child nutrition after controlling for the effect of education on income and fertility [103]. Bairagi [104] found in Bangladesh that increased income had a greater impact on the nutritional status of children of literate mothers than on those of illiterate mothers.
The mechanism through which education is presumed to act is through women's better management of household resources. Rosenzweig and Schultz [105] found in Colombia that maternal education can compensate to some extent for lack of access to public health and family-planning services. In rural areas, maternal education - but not health institutions or public expenditures - was associated with reduced child mortality. Another study in Nicaragua, however, found that the impact of women's education on their health and on child nutrition disappeared after controlling for community and material endowments [106].
Women's education is also associated with lower fertility [107], which constitutes management of reproductive resources. Lower fertility by itself has been associated with improved maternal and child health.
In Mexico, LeVine et al. [108] found educated women to be more aware of the larger world and to have made a higher use of health-care services (prenatal care, well-child care). Most importantly, they found that, with more education, women changed their behaviour toward their children: they became more child-centred. Tucker and Sanjur [109] found in Panama that a mother's "differentiation" (which incorporates nutrition knowledge, formal education, frequency of reading, and participation in home production) is consistently related to better diets and improved nutritional status for her children even when employment is taken into account. On the other hand, increased maternal education is associated with decreased breast-feeding, which increases infant morbidity and mortality.
aldwell [110] maintains that an educated woman is more successful in child-rearing because (1) she is less tradition-bound and more likely to try innovative solutions to her problems; (2) she is more "capable of manipulating the modern world"; (3) she tips the balance of power in the household in her favour; and (4) she is more likely to challenge her husband or mother-in-law and they are more likely to accept her judgement.
Maternal education, behavioural-change messages, and technology can positively affect these child outcomes without significant changes in household incomes. A nutrition-education project in Indonesia which modified specific child-feeding and care-giving behaviours erased the adverse effects of low levels of maternal education on nutritional status [111]. This finding suggests that maternal education acts through maternal-child interactions to improve nutrition. Similarly, evidence from Bangladesh [112] also suggests that education and even appropriate technology (jute playpens) can compensate for or replace childcare behaviours that promote malnutrition.
Little is known of women's management of household finances, food supplies, and the labour they control. One would assume that technology and institutional support (consumer co-operatives, for instance) might improve women's home-production efficiency. Numerous studies [e.g., 113] show that education affects women's agricultural productivity positively, suggesting that other spheres of work (including market and home production) might be responsive to female education [24].
Women's self-confidence
Women's lack of self-confidence has been cited as a major determinant of programme success in maternal-child health [114]. Lack of self-confidence has also been called "silence," extreme in self-denial and dependence on external authority for direction [115]. Silence keeps women from seeking help for themselves and their children - whether it is prenatal care, education, or fair wages. Authority figures have been used to persuade women to seek family planning or prenatal care or to continue breast-feeding, but increasing women's self-confidence is needed to help them to change behaviour and use an array of services and commodities correctly.
- Griffiths [114] found in Swaziland that mothers had sufficient self-confidence to persist in feeding their anorectic children even when the sick children refused to eat. In Cameroon, on the other hand, the mother cedes power to the child and gives in to its self-destructive behaviour. Differences in the mothers' self-images are positively correlated with their children's health and nutrition.
- Kagitcibasi [see 116] found in Turkey that, to reach children successfully, it was necessary to build self confidence in the mothers. To educate women about stimulating early cognitive development, women were first given tasks they could successfully complete, such as feeding the child. Not surprisingly, husbands and mothers-in-law sometimes disapproved of the programme because it gave women self-assurance, but it has been successful in terms of participation rate, educational measures, and broadly applicable maternal skills.
- In India, Griffiths [114] found that mothers felt powerless to undertake independent action. As a result, fathers and grandmothers of at-risk children are educated. Mothers are encouraged to come together to listen to and discuss a radio programme designed to motivate them to change some behaviours.
With self-confidence, women will have greater success in breast-feeding, introducing weaning foods, changing practices, and persisting in recommended behaviours against resistance by the child or by opinion leaders in the household and community.

During each stage in the life cycle, females have clear cut biological, economic, and cultural roles. In table 10 we present these roles, some of the obvious conflicts, and the adverse effects on women and their families. In numerous cultures, girls are seen as a net drain on family welfare. From birth onward, girls in some parts of the world receive less food, nurturing, and health care than boys, with important effects on growth, development, and survival. Socialization of girls to be acquiescent and self-sacrificing adds additional nutritional stress if it reduces their access to food. Older girls experience conflicts over their use of time: instead of playing or attending school, they are expected to work at home or on the family farm. At times these tasks cause energy conflicts: carrying water and babies may require so much of the girls' energy that they have none left for growth or learning from their environment. Heavy disease and parasite burdens limit their available energy, so a heavy work load thrusts a double load on children. While boys and girls tend to be assigned productive work, the long-term nutritional implications are worse for girls. If female growth is stunted, reproductive risks increase. Moreover, boys' school enrolment usually exceeds that of girls, which effectively increases the girls' work load and exacerbates their disadvantages in the labour market.
As girls mature, their economic contribution to the household increases, but cultural expectations for early marriage and child-bearing detract from their economic and biological well-being. Once married, the number of conflicts among women's roles increases.
Women of child-bearing age are under the greatest role stress. In particular, child-bearing incurs high costs to the mother (who spends her income disproportionately on children) at the same time that it reduces her income-earning capacity. Collier [117] argues that this situation makes women perfect candidates for savings and credit schemes - borrowing to finance consumption while their children are very young and saving money when their child-care burden decreases sufficiently to enable them to become net earners again. Their management of resources as mothers, wives, income earners, and individuals determines their welfare and their family's welfare. The conflicts they encounter are detailed in the next section.
After they leave child-bearing behind, women often gain considerable respect, power, and economic control. Because they are no longer sexually threatening, older women are freer to operate in the markets, manage their own farmland, and make household decisions. In patriarchal societies, widows may have access to productive resources only through their sons, brothers-in-law, or brothers, but usually older widows have sufficient freedom of movement to participate in market activities where younger females are secluded and veiled. The livelihoods open to aged women may barely allow them a subsistence wage. Because women have greater life expectancy than men, they need to be economically competent, but failing health and reduced strength may jeopardize their ability to support themselves.
The closed system of women's time, energy, and income
Crucial conflicts face poor women in low-income countries as they try to fulfil their economic, biological, and social roles at each stage in the life cycle, particularly during the child-bearing years. Changes in behaviour that enhance their contribution to one role can have crucial negative effects on their other roles and activities. This role conflict relates to the tremendous time, energy, and money-resource constraints facing these women. The resources are interchangeable above certain minimal levels of requirements; however, resource shortages and bottlenecks preclude women from making significant substitutions among resources. Conflicts between the economic, reproductive, and cultural roles of women can have detrimental effects on their nutrition and/or that of their families.
Biological versus cultural roles
The status and quality of life of poor women are inseparable from their reproductive role in many societies. For example, primary and secondary infertility, important problems in sub-Saharan Africa, carry with them a certain degree of social and economic ostracism [118; 119]. On the other hand, women who give birth to one or more children (preferably male in many societies) gain important benefits. This childbearing role is stressful. Repeated pregnancies, numerous known and unknown foetal deaths, delivery complications, and extensive periods of lactation have significant adverse effects on women's energy and nutrient stores as well as on their physical performance.
Some researchers postulate the existence of a maternal-depletion syndrome related to repeated and closely spaced pregnancies and extended lactation [53; 120]. Under this scenario a woman with inadequate nutrient intake may not be able to replenish energy reserves between pregnancies. Each additional pregnancy and bout of illness thus further compromises her nutritional status. As discussed above, up to 33%-50% of a women's reproductive life is spent being pregnant and/or lactating.
An extensive body of literature documents the effects of repeated, closely spaced pregnancies on two key reproductive outcomes - birth weight and child survival. While this research ignores the woman's nutritional condition, it has found that short birth intervals, particularly under 24 months, are associated with increased risks for the infant [123-125]. Since the maternal environment is the source of most immediate risk factors, this association of birth spacing with infant health indirectly supports the maternal depletion hypothesis.
Strong positive relationships between maternal mortality, age, and parity also provide evidence of maternal depletion [126]. In general, maternal mortality increases with age, with a sharp rise found after age 30-34. Similar relationships are found with parity increases above three. Some studies have also linked spacing in a crude manner with these age and parity relationships.
Multivariate analysis has encountered methodological problems in confirming those relationships [124; 127; 128]. While these studies have focused mainly on infant health, they have begun to consider carefully the effects on the mother, in particular the conceptual and statistical issues that must be considered to examine these issues adequately.
Economic versus cultural roles
Poor women are expected to play the central role in child care and food processing even when their economic roles also require extensive time and/or physical energy. This responsibility causes several conflicts.
Women are expected to nurture the infant or preschooler and concurrently play a key role in family economic life. Particularly in societies where female headed households abound, or in areas where economic roles take the women away from the household and are otherwise incompatible with child care (e.g., many urban settings, selected rural ones), many nurturing roles cannot be fulfilled. In addition to the one-quarter to one-third of households headed by women, a large number of de facto female-headed households have resulted from increased male migration in recent years.
A major debate exists concerning the consequences of maternal market employment on the health and development of children [129; 130]. The importance of this debate has increased as urbanization and industrialization have increased the proportion of women in the paid labour force - which has risen from 28% in 1950 to 32% in 1985 [31]. Of some concern, however, is the increase in informal-sector employment of women, especially piece work done at home, that can expose women and children to dangerous chemicals and other hazards [131].
When mothers work away from their children, breast-feeding may be very short or not even initiated, weaning food may be contaminated and of poor nutritional quality, and poor child-care substitutes (or non-existent ones) leave the infant vulnerable to infection and malnutrition [132]. O'Gara [133] and Oppong and Abu [134], however, provide examples of working mothers who have been able to continue breast-feeding in spite of employment. Leslie [135] summarizes this literature. Women engaged in market work often have malnourished children, but it is difficult to unravel a clear causal relationship between women's employment and child nutrition.
The belief that certain kinds of employment (for instance, agriculture, home-based industry, and market work) are compatible with child care because the mother is present may be incorrect [137]. Presence alone does not guarantee that the mother is interacting with her child, and the quality of care may be worse under these conditions. It is unclear whether urban low-income women are any less able to engage in work compatible with child care than are rural women [41]. For instance, in agricultural fields or public marketplaces, certain health hazards may outweigh the benefits of the mother's presence. Where precision and concentration are important, women may have to neglect their children to gain an income. A major issue related to modifying any negative relationship between maternal work and child nutritional status is the quality of the child-care substitutes (see below).
Biological versus economic roles
One conflict relates to women's child-bearing roles. Poor women in most societies continue to undertake heavy physical activity during pregnancy and resume this activity soon after delivery of their children. Extreme physical stresses may result in additional foetal loss, prematurity, or low birth weight [138]. In addition, reduction in work time or work productivity associated with childbirth and lactation may adversely affect the family's income and food security.
Pregnant and postpartum women have very heavy work loads in most low-income countries. In a cross cultural study of 202 traditional societies, the most common single pattern of work activity during pregnancy was that of continuing full duties until the onset of labour [139, p. 173].10 Women in 66% of these societies worked until labour, and an additional 14% stopped only in the ninth month. Women in about half of the societies resumed work within two weeks of birth. Another quarter of the societies reported women's return to full activity in the fifth or sixth week, and in only 12% did women rest for two or more months postpartum.
Extensive physical activity while pregnant may have an adverse effect on pregnancy outcome. A number of components of physical activity can be harmful to the foetus. A major factor hypothesized to have an adverse effect on pregnancy outcome is physical stress [140], which may occur in combination with poor nutrition [141], fatigue [142; 143], or harmful body posture [144]. Various dimensions of low income women's work in home and market activities may have significant adverse effects on pregnancy outcome [138].
Effects of this double burden on women and their offspring are considerable. Roughly 20 million infants worldwide (about 17.6% of all births in low-income countries) are born with weights below 2,500 g [145]. In developing countries about 80% of low birth weight (LBW) is from intra-uterine growth retardation, largely a result of maternal malnutrition [122; 146]. The resultant effects of LBW and/or pre-term status on growth, survival, and development are well documented [100]. Repeated miscarriages, stillbirths, and foetal losses combine with the LBW-related infant deaths to potentiate the effects of mothers' cultural roles on their nutritional status - issues discussed above.
Second is the conflict between women's economic roles and their own nutritional needs. This issue is affected by changes in energy expenditures and intra-household food allocation associated with an enhanced economic role for women. Increased economic participation may increase energy expenditures - for instance, for women engaged in agricultural labour.
A crucial linkage is the impact of women's economic roles on household food security and the intra-household allocation of food. The few studies on intra-household allocation of food show that women get less food than men both in absolute terms and relative to their nutritional needs [52; 147; 148]. There is some evidence that a mother's income goes more directly to her child than that earned by the father [149; 150]. In most low-income societies women's roles involve them in purchasing food, while males purchase other types of goods and services.
A woman's access to and control over income and assets would be a major determinant of her dietary adequacy [52]. Income control enables women to decide whether to trade food items within a social or marketing network or to consume household food production. Within some cultures, the woman's contribution to household income is a direct measure of her economic influence and social value. Some argue that economic power is the most important determinant of women's relative equality, which affects decision making, life-style options, and control of resources such as food [151; 152].
Recent reviews of intra-household resource allocation suggest that the nutritional impact of increased household income is a function of income earner, source of income, its periodicity and reliability, and kind of income (cash or goods) [153; 154].
Market work affects personal dietary needs through occupational energy requirements. Poor women, particularly in rural areas, are more likely to engage in strenuous physical labour that increases their energy needs. They have fewer time- and energy-saving household assets such as piped water and gas or kerosene stoves. They cannot afford child-care substitutes or labour-saving purchases such as processed or prepared foods. Energy expenditures and needs are thus closely intertwined with income and time allocation decisions discussed below.
Enhancing resource availability, allocation, and efficiency: Programme and policy responses
Policies and programmes affecting women and nutrition can be lumped into two categories - intentional and unintentional. All too often, actions have unintentional yet detrimental effects on women. Structural adjustment, for instance, may rectify foreign-exchange imbalances but may compromise the low-income family's consumption basket. Women as consumers, child-readers, nutritionally vulnerable people, and income earners are acutely affected by fiscal constraint, economic restructuring, and changing prices of foodstuffs. National policies, even some with positive social outcomes in mind, may have important negative effects on women.
Deliberate attention to women's multiple roles needs to accompany any analysis of policy change lest economic efficiency and welfare (including nutrition) be compromised.
Women divide their day among three major types of activities: market production, household production, and investment/restorative activities (sleep, learning, fostering social ties). Development programmes and policies often entail some reallocation of time within or between these areas, either temporarily or permanently. To predict the effect of this reordering of tasks on nutrition necessitates examining the direct and indirect adjustments. Figure 5 (see FIG. 5. The effect of women's time allocation on nutrition) shows how development efforts can affect nutrition positively by changing the way women use their time. Each concentric circle represents increased resources for nutrition, with the outermost circle containing more distal effects than the inner circle. The resulting improvements in human resources then enhance productivity, further generating, one hopes, an upward spiral in output and well-being.
Of course we cannot increase the number of hours in the day, but, by increasing productivity (through increasing skills, improving technology, or providing access to productive resources, shown inside the arrows in figure 5), we can help women to either increase their output or decrease the time necessary to produce the same output in market or household production. With this added output (or thee), they can improve the household food supply, health, and child care, and their own work load. This in turn results in improved health and nutritional status for all members of the family, reduced stress, and enhanced female status.
In order for women to be able to get more rest or invest in their own human or household resources, they need increased productivity, as described above, but also the motivation and permission to use their newfound time for sleep, for using health or education programmes, or for spending more time taking care of their children. Sleep and rest are productive uses of time to the extent that they reduce nutritional depletion and restore energy stores in the muscles and fat, thus increasing strength and endurance. Reduced maternal energy expenditure (if it is not matched by reduced dietary intake) may also make more nutrients available to the foetus or nursing child. Increased time spent on child care is productive if it enhances the child's health or development, which is promoted through maternal skill-building efforts.
Opportunities do exist for intentionally improving nutrition through addressing women's needs. The linkages between immediate project outcomes and nutrition are not necessarily direct, however, and the effectiveness of an intervention in improving nutritional status may vary from one population to another. Part 2 of this paper will address these issues and review programmes and policies to create a positive-sum game by addressing the issues of income, child care, productivity, and health. Urgent issues requiring further research will be summarized.

Notes
1. There results represented studies with more than 20 women as subjects from low-income countries in Asia and Africa. Approaches for collecting these data vary widely from careful, precise observation of activities to recall of one to seven days of activity. Market work includes all agricultural, wage, animal husbandry, and handicraft activities. Home production includes child care, food marketing/preparation, washing, cleaning, caring for the sick, and other activities traditionally not remunerated Leisure activities were excluded since their measurement depended on the length of daily observation in each survey.
2. Fertility and lactation experiences are reviewed by using nationally representative, comparable surveys conducted in a large number of countries. The results presented in table 7 and figure 2 are based on standardized tabulations for 27 countries prepared by the International Statistical Institute in the first Country Report for the World Fertility Surveys. Most of these surveys were conducted in the 1970s. In a technical appendix available on request, we present the methods used to derive the Iength of time a women is pregnant or lactating. These results represent a conservative estimate of the number of months of pregnancy because of very low estimates of the number ending in miscarriage or stillbirth. Also we assume that a woman's reproductive life is 35 years, a time longer than the span in many low-income countries.
3. Little is known about the functional significance (e.g., on physical performance in home or market production) of various distributions of dietary intake, weight, or fat composition, inter alia.
4. A number of researchers, particularly the group involved in a large comparative study of energy requirements during pregnancy and lactation, feel that these RDAs overestimate the women's needs [87; 88]. If their findings are correct, women may not be as undernourished as these data suggest.
5. We use weight-for-height standards for US women with small frames to obtain some sense of the distribution of women in terms of body composition.
6. The description of the maternal-depletion syndrome began with a broadly based set of factors: physically demanding labour, poor diet, heavy infection levels, and repeated pregnancies. It has narrowed over time to a focus on repeated pregnancies and prolonged lactation [see, e.g., 121].
7. Brems and Berg [122] hypothesize that many women in low-income countries, particularly those without access to modern obstetrical care, may not adequately increase their diet during pregnancy. They hypothesize, in fact, that in many cases they may decrease it because of fear of delivery complications felt to be associated with pelvic disproportionality. "Eating down" during pregnancy, they feel, may be a rational response. This hypothesis is unexplored. Brems and Berg cite a set of anthropological studies documenting beliefs on food avoidance or reduced weight gains during pregnancy; unfortunately none has documented the impact of these beliefs on dietary behaviour [cf. 52].
8. More systematic research on this question following a more comprehensive biological systematic research on this question following a more comprehensive biological model and using longitudinal research on 3,000 Filipino women is being conducted by Linda Adair, Eilene Bisgrove, and Barry Popkin. Initial multivariate findings indicate a strong relationship between the duration of lactation and postpartum weight loss.
9. Researchers on this topic ignore some crucial issues, including the sequencing of maternal work and child-care outcomes and the nature of the decision-making processes concerning maternal work and child-feeding decisions. If women make decisions jointly to work and to cease breast-feeding (or other feeding choices), if they go to work because they need to try to improve poor child nutrition, or if those who work away from the home have less concern for infant well-being than those who select jobs compatible with child care - jobs that are lower paying - then, although poorer child nutrition may be associated with women's work, it would not be women's work per se that has caused this relationship. These issues must be considered before we can understand whether and how women's economic roles conflict with child-care roles. These shortcomings and problems must be considered in examining the broad sets of conclusions found by the numerous studies on this topic [cf. 135; 136].
10. It is not clear whether these 202 societies are representative of modern third-world societies. Data came from the Human Area Relations file, representing predominantly isolated rural groups.
