Nutrition interventions that target mothers alone inadequately address women's needs across their lives: during adolescence, preconception, and in later years of life. They also fail to capture nulliparous women. The extent to which nutrition interventions effectively reach women throughout the life course is not well documented. In this comprehensive narrative review, we summarized the impact and delivery platforms of nutrition-specific and nutrition-sensitive interventions targeting adolescent girls, women of reproductive age (nonpregnant, nonlactating), pregnant and lactating women, women with young children <5 y, and older women, with a focus on nutrition interventions delivered in low- and middle-income countries. We found that although there were many effective interventions that targeted women's nutrition, they largely targeted women who were pregnant and lactating or with young children. There were major gaps in the targeting of interventions to older women. For the delivery platforms, community-based settings, compared with facility-based settings, more equitably reached women across the life course, including adolescents, women of reproductive age, and older women. Nutrition-sensitive approaches were more often delivered in community-based settings; however, the evidence of their impact on women's nutritional outcomes was less clear. We also found major research and programming gaps relative to targeting overweight, obesity, and noncommunicable disease. We conclude that focused efforts on women during pregnancy and in the first couple of years postpartum fail to address the interrelation and compounding nature of nutritional disadvantages that are perpetuated across many women's lives. In order for policies and interventions to more effectively address inequities faced by women, and not only women as mothers, it is essential that they reflect on how, when, and where to engage with women across the life course.
Women's health is positioned within a wider body of knowledge cited by, amongst others, the World Health Organization, which places importance on gender as a social determinant of health. While women's health is affected by their biology, it is also affected by their social conditions, such as poverty, employment, and family responsibilities, and these aspects should not be overshadowed.
The guidelines also establish ranges (called acceptable macronutrient distribution ranges or AMDR) for fat, carbohydrates and protein, instead of exact percentages of calories or numbers of grams. The report maintains that since all three categories serve as sources of energy, they can, to some extent, substitute for one another in providing calories.
Research is a priority in terms of improving women's health. Research needs include diseases unique to women, more serious in women and those that differ in risk factors between women and men. The balance of gender in research studies needs to be balanced appropriately to allow analysis that will detect interactions between gender and other factors. Gronowski and Schindler suggest that scientific journals make documentation of gender a requirement when reporting the results of animal studies, and that funding agencies require justification from investigators for any gender inequity in their grant proposals, giving preference to those that are inclusive. They also suggest it is the role of health organisations to encourage women to enroll in clinical research. However, there has been progress in terms of large scale studies such as the WHI, and in 2006 the Society for Women's Health Research founded the Organization for the Study of Sex Differences (OSSD) and the journal Biology of Sex Differences to further the study of sex differences.
Anaemia is a major global health problem for women. Women are affected more than men, in which up to 30% of women being found to be anaemic and 42% of pregnant women. Anaemia is linked to a number of adverse health outcomes including a poor pregnancy outcome and impaired cognitive function (decreased concentration and attention). The main cause of anaemia is iron deficiency. In United States women iron deficiency anaemia (IDA) affects 37% of pregnant women, but globally the prevalence is as high as 80%. IDA starts in adolescence, from excess menstrual blood loss, compounded by the increased demand for iron in growth and suboptimal dietary intake. In the adult woman, pregnancy leads to further iron depletion.
Interventions resulting in public infrastructure changes were found to be less effective than household-based interventions; however, both are important aspects of improved health outcomes for women (128, 130). Public water infrastructure requires regular maintenance and periodic replacement and water from these sources is often contaminated (130). However, even public water points that provide good-quality water have had minimal impacts on health outcomes (136). One review estimated that water-source interventions were associated with a 27% reduction in diarrhea risk at all ages, whereas household-based interventions were associated with a 43% reduction (128). This could be associated with bias and confounding, as measuring WASH outcomes is not a blinded process (128). The differential impact could also be related to practice. As compared with public water sources, home water connections were associated with greater odds of handwashing and fecal waste disposal (136). As a significant portion of diarrheal disease is a result of person-to-person transmission and poor hygiene, interventions that improve domestic hygiene behaviors can have a significant impact (136). Behavior change communication and resource provision, e.g., soap and point-of-use water treatment resources, were also important and sustainable aspects of WASH interventions (131, 137).
Breast cancer is the second most common cancer in the world and the most common among women. It is also among the ten most common chronic diseases of women, and a substantial contributor to loss of quality of life (Gronowski and Schindler, Table IV). Globally, it accounts for 25% of all cancers. In 2016, breast cancer is the most common cancer diagnosed among women in both developed and developing countries, accounting for nearly 30% of all cases, and worldwide accounts for one and a half million cases and over half a million deaths, being the fifth most common cause of cancer death overall and the second in developed regions. Geographic variation in incidence is the opposite of that of cervical cancer, being highest in Northern America and lowest in Eastern and Middle Africa, but mortality rates are relatively constant, resulting in a wide variance in case mortality, ranging from 25% in developed regions to 37% in developing regions, and with 62% of deaths occurring in developing countries.
Poor nutrition may be one of the easiest conditions to self-diagnose. Look at the food pyramid and the suggested servings. Look at your diet. Are you getting the recommended daily amounts of fruits and vegetables? Enough calcium? Read the labels and compare what you eat to what you need. You may discover that even if your weight is ideal, you are not getting enough nutrition.
You know it's easier to fall off the healthy-eating wagon when the person across the table from you is going whole-hog on mozzarella sticks, but science still felt the need to study this. And evidence presented at the 2013 Agricultural and Applied Economic Associations annual meeting backs you up: In the study, people made similar dining choices as their companions did, possibly because we simply want to fit in. Not all eating partners make a bad influence, though. The report further speculates that if you're eating with a health-conscious person, you may be more likely to order something more nutritious as well.
Calcium: “Getting enough calcium is important for all ages, but it's particularly important during adolescence and early adulthood, when bones are absorbing calcium,” says Heather Schwartz, MS, RD, a medical nutrition therapist at Stanford University Hospital and Clinics. Calcium and vitamin D are often paired in fortified foods such as milk. The reason: The body needs D in order to absorb calcium.
Lipid-based nutrient supplement (LNS) programs are intended to enrich diets with micronutrients and essential fatty acids (97), and are often used in emergency settings to meet nutritional needs of pregnant and lactating women (98). Of the studies that report on women's health outcomes, LNSs provided to pregnant and lactating women increased body weight and midupper arm circumference, particularly of multiparous women and women >25 y of age (99). They were associated with increased plasma α-linoleic acid, although not plasma lipids and other fatty acids (100). LNSs did not affect women's immune responses, particularly pregnant women's anti-malarial antibody responses (101). There was limited evidence connecting LNS supplementation to unhealthy weight gain and retention, and this is being explored in ongoing studies in Ghana (97).
Among other things, you need calcium to build healthy bones and teeth, keep them strong as you age, regulate the heart’s rhythm, and ensure your nervous system functions properly. Calcium deficiency can lead to, or exacerbate, mood problems such as irritability, anxiety, depression, and sleep difficulties. If you don’t get enough calcium in your diet, your body will take calcium from your bones to ensure normal cell function, which can lead to weakened bones or osteoporosis. Women are at a greater risk than men of developing osteoporosis, so it’s important to get plenty of calcium, in combination with magnesium and vitamin D, to support your bone health.
Give your body a little more credit: It tells you when you’re hungry—you may not be listening, though. Before chowing down because there’s only one slice of pie left or because the last guest arrived at the brunch, stop and check in with your stomach. “If you’re not hungry, make yourself a small plate and sip on some tea or coffee while everyone else digs in,” recommends Elle Penner, M.P.H., R.D., a MyFitnessPal expert. When your belly starts to finally grumble, food will be there.
One of the challenges in assessing progress in this area is the number of clinical studies that either do not report the gender of the subjects or lack the statistical power to detect gender differences. These were still issues in 2014, and further compounded by the fact that the majority of animal studies also exclude females or fail to account for differences in sex and gender. for instance despite the higher incidence of depression amongst women, less than half of the animal studies use female animals. Consequently, a number of funding agencies and scientific journals are asking researchers to explicitly address issues of sex and gender in their research.
