Moderate malnutrition continues to affect 46% of children under five years of age and 47% of rural women in India. Women's lack of empowerment is believed to be an important factor in the persistent prevalence of malnutrition. In India, women's empowerment often varies by community, with tribes sometimes being the most progressive. ⋯ In addition to the known investments needed to reduce malnutrition, improving women's nutrition, promoting gender equality, empowering women, and ending violence against women could further reduce the prevalence of malnutrition in this segment of the Indian population.

Deficiencies of micronutrients such as iron, zinc, and vitamin A afflict over three billion people (more than 50% of the world's population), most of them women, infants, and children in resource-poor families in the developing world. This global crisis in nutritional health is the result of dysfunctional food systems that do not consistently supply enough of these essential nutrients to meet the nutritional requirements of high-risk groups. Deficiencies of micronutrients result in increased morbidity and mortality rates, lost worker productivity, stagnated national development, permanent impairment of cognitive development in infants and children, and large economic costs and suffering to those societies affected. ⋯ Biotechnological advances show great promise for improving the output of bioavailable micronutrients from agricultural systems that feed the poor. This paper reviews some of these opportunities and discusses the questions and concerns that should be raised when these technologies are used to improve the micronutrient status of vast numbers of people who are dependent on staple food crops for their sustenance. Further, important issues surrounding micronutrient bioavailability and plant food factors that affect it are discussed.

The 1997 Demographic and Health Survey in Mozambique shows that 47% of girls 15 to 19 years old living in Manica province (west-central Mozambique) are pregnant or have already had a child. A recent survey also shows that 45% of girls 10 to 18 years old attending school are anemic. Strategies are needed to build iron stores before pregnancy and to control seasonal and chronic iron deficiency and anemia in school-aged girls. ⋯ In Manica Province, school-based weekly IFA supplementation is a feasible and effective intervention to prevent seasonal drops in hemoglobin concentration and increases in anemia prevalence. Short supplementation periods can have an important impact on girls' hematological status. However, the size of girls' hematological response in this study was significantly lower that that observed in studies with similar population groups, initial anemia prevalence, supplement dosing, and/or supplementation regime.

Micronutrient-deficiency control programs have been greatly extended at the national level in the last 10 to 15 years. However, rigorous evaluations of these are scarce, so that conclusions on impact are tentative and based mainly on indirect evidence. The coverage of vitamin A capsule distribution programs has exceeded 70% in most study countries. ⋯ Although trials have demonstrated the efficacy of iron supplementation in reducing the prevalence of anemia, the interpretation of national-level data is not so clear. Given the substantial financial and technical commitment required to implement national micronutrient-deficiency control programs, it is vital that investment enable the evaluation of the impact of these programs. It is becoming increasingly important to collect data on subclinical deficiency (e.g., biochemical data) to assess program impact.
