Evaluations of protein-energy supplementation were limited to specific situations and contexts, and few studies evaluated national-scale programs (14, 33). National-level protein-energy supplementation programs for women and adolescent girls are expensive and challenging to implement compared with other efficacious interventions (33). Procuring, preparing, and distributing food and appropriately targeting women most in need (e.g., women below the poverty line, women who have or are at high risk of malnutrition, etc.) present challenges to protein-energy supplementation interventions (33).
Third, of the interventions that were evaluated, many interventions targeted women who were pregnant, lactating, or with young children <5 y of age. We do not refute the important focus on mothers and their children as a group deserving of special attention, given women's increased nutrient needs during pregnancy and lactation and the intergenerational consequences during this period. However, even the interventions that focused on maternal nutrition often only reported on birth and nutrition outcomes of the child, and not those of the mother. In addition, although there were interventions that targeted adolescent girls and women of reproductive age, they were fewer and less well evaluated than interventions that targeted women as mothers. This aligns with findings from other research which illustrated a higher proportion of programs targeting pregnant and lactating women and women with young children (209). We also found major gaps in the targeting of interventions for older women. With growing rates of overweight, obesity, and noncommunicable diseases, in addition to undernutrition and micronutrient deficiencies, it is essential to think outside of the maternal-focused paradigm to reach women at all life stages.
In our review, we found that fortification interventions that provided fortified foods reached women of all life stages through home visits, community distribution centers, local markets, and retail stores. Delivery of fortified foods in school-based programs, at work, and in maternal–child health centers were also used to target school-age children, women of reproductive age, and pregnant and lactating women that were engaged with those facilities (37, 72–74, 84). There was mixed evidence that consumption of fortified foods reached all socioeconomic groups. Some studies showed differences in consumption between nonpoor and extremely poor, and between urban and rural stakeholders (33, 64, 85). Women who have restricted access to markets, depend largely on locally grown foods, are in areas with underdeveloped distribution channels, or have limited purchasing power, might have limited access to fortified foods (64). Additional research is needed to address implementation gaps and to determine the best platforms for reaching high-risk populations.
Women's health refers to the health of women, which differs from that of men in many unique ways. Women's health is an example of population health, where health is defined by the World Health Organization as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity". Often treated as simply women's reproductive health, many groups argue for a broader definition pertaining to the overall health of women, better expressed as "The health of women". These differences are further exacerbated in developing countries where women, whose health includes both their risks and experiences, are further disadvantaged.
