Second, the scope of nutrition-specific and nutrition-sensitive approaches was largely focused on undernutrition. There were major research and programming gaps in studies targeting overweight, obesity, and noncommunicable disease. In our review, the interventions addressing overweight, obesity, and noncommunicable disease were limited to nutrition education and integrated healthcare. However, overweight and obesity were identified as potential concerns for interventions targeting undernutrition, including food supplementation, and in-kind and cash transfers. This might be a result of the types of interventions that were evaluated, but also speaks to the need to broaden the scope of nutrition interventions that are commonly assessed (5, 13, 14) to explicitly address overweight, obesity, and noncommunicable disease as nutrition outcomes, and not just as unintended consequences. Globally, there is limited evidence of large-scale interventions that effectively prevent, treat, or correctly classify adiposity-related noncommunicable diseases, and this is a growing area of concern around the world (208). Future evaluations of nutrition interventions might also include interventions that influence women's time and physical environment, and that encourage physical activity or change in access to and affordability of certain foods, as these might also influence overweight, obesity, and noncommunicable disease outcomes for women.
Fourth and finally, there was a general lack of focus on the relevant delivery platforms for nutrition interventions. Many studies were not explicit about how and where interventions were delivered, and we had to cross-reference multiple sources to identify the delivery platform for many interventions. Delivery platforms are important and relevant information in terms of replicability, but also for identifying who is effectively reached and missed. Information about delivery platforms is also instrumental in understanding gaps in implementation. A greater emphasis on delivery platforms could enhance the reach of nutrition interventions and could also strengthen the capacity to mobilize resources more effectively. For instance, organizing and grouping interventions by delivery platform (e.g., antenatal care, community centers, schools, clinics) or by the relevant stakeholders required for delivery (e.g., ministries, health care providers, teachers, administrators, transporters, etc.) could have the potential to more efficiently deliver nutrition interventions.
Social protection interventions are intended to support vulnerable households by providing them with in-kind (e.g., food) or cash transfers. The impact of social protection on women's nutrition was nuanced, as such interventions were associated with protecting against adverse nutrition outcomes, but were also associated with excess weight gain in some settings. In-kind transfers, including food baskets, fortified foods, and school lunches, improved women's and adolescent girls’ energy and micronutrient intakes, as described in the preceding sections. Both CCTs and unconditional cash transfers were common around the world and were associated with improvements in health care utilization and increased food expenditures (5, 14, 195, 196). CCTs were dependent on “conditions” such as school attendance and health care utilization. For children in Burkina Faso, CCTs were associated with greater numbers of preventative health visits compared with unconditional cash transfers (197), and this could be relevant to adult women's health care utilization as well. Unconditional cash transfers, such as old-age pensions, were also common, including in low- and middle-income countries (5, 198). Older women who received pensions had fewer missed meals (199), although evidence was mixed (200). In South Africa, granddaughters who cohabitated with women who received pensions had improved anthropometric measures and fewer missed meals, indicating spillover effects of pension transfers (199, 201).
A 55-year-old woman who gets less than 30 minutes of daily physical activity should eat five ounces of grains; two cups of vegetables; one and a half cups of fruit; three cups of milk; five ounces of meat and beans; five teaspoons of oils, and no more than 130 calories of additional fat and sugar. If she got 30 to 60 minutes of daily exercise, she could increase her intake to six ounces of grains; two and a half cups of vegetables; and up to 265 additional calories of fat and sugar.
