Family planning and birth spacing can influence the nutrition of adolescent girls, women of reproductive age, and women with young children by reducing the number of adverse outcomes associated with pregnancy and abortion. For adolescent girls, in particular, pregnancy is associated with increased risk of birth complications, anemia, hindered linear growth, and loss of educational attainment (8, 107). Delaying early child marriages and providing access to family planning, particularly for young wives, allow girls to achieve their maximum growth potential (8, 142). However, for women with young children, there was scarce evidence from observational studies to suggest that greater birth spacing had any impact on anthropometric status (BMI, weight), micronutrient status (anemia, as well as serum zinc, copper, magnesium, and folate), and maternal mortality outcomes (13, 107, 143–147). Findings were mixed, which was attributed to sample size and other confounding factors such as maternal age, breastfeeding status, and supplementation status (146, 147). The strongest evidence of the impact of birth spacing on women's nutrition was related to increased risk of preterm delivery and maternal anemia in interpregnancy intervals <6 mo (14, 146, 147) and increased risk of pre-eclampsia in intervals >5 y (107).

Abortion is the intentional termination of pregnancy, as compared to spontaneous termination (miscarriage). Abortion is closely allied to contraception in terms of women's control and regulation of their reproduction, and is often subject to similar cultural, religious, legislative and economic constraints. Where access to contraception is limited, women turn to abortion. Consequently, abortion rates may be used to estimate unmet needs for contraception.[71] However the available procedures have carried great risk for women throughout most of history, and still do in the developing world, or where legal restrictions force women to seek clandestine facilities.[72][71] Access to safe legal abortion places undue burdens on lower socioeconomic groups and in jurisdictions that create significant barriers. These issues have frequently been the subject of political and feminist campaigns where differing viewpoints pit health against moral values.

Food fortification is one of the most cost-effective strategies to improve micronutrient status through a variety of food vehicles, including staples, condiments, and processed foods (63, 64). Common fortifiable micronutrients include iron, folic acid, vitamin A, vitamin D, vitamin E, and iodine, although B vitamins and vitamin C are also used as fortificants (33, 64). Food fortification reduced anemia and iron deficiency anemia, and improved vitamin A, folate, niacin, thiamin, vitamin B-6, vitamin B-12, zinc, and iodine status of women of reproductive age and adolescents (13, 46, 61, 63–74). Vitamin D and calcium fortification were found to reduce the risk of osteoporosis among older women, especially for those exposed to inadequate sunlight (63, 64). Biofortification efforts, including those that involved breeding or genetic modification of plants to improve micronutrient content, have also shown improvements in the vitamin A and iron status of women (64, 75). Similar to micronutrient supplementation, women and girls with low micronutrient status were most likely to benefit.
A related issue is the inclusion of pregnant women in clinical studies. Since other illnesses can exist concurrently with pregnancy, information is needed on the response to and efficacy of interventions during pregnancy, but ethical issues relative to the fetus, make this more complex. This gender bias is partly offset by the iniation of large scale epidemiology studies of women, such as the Nurses' Health Study (1976),[162] Women's Health Initiative[163] and Black Women's Health Study.[164][6]
Almost 25% of women will experience mental health issues over their lifetime.[126] Women are at higher risk than men from anxiety, depression, and psychosomatic complaints.[17] Globally, depression is the leading disease burden. In the United States, women have depression twice as often as men. The economic costs of depression in American women are estimated to be $20 billion every year. The risks of depression in women have been linked to changing hormonal environment that women experience, including puberty, menstruation, pregnancy, childbirth and the menopause.[119] Women also metabolise drugs used to treat depression differently to men.[119][127] Suicide rates are less in women than men (<1% vs. 2.4%),[27][28] but are a leading cause of death for women under the age of 60.[17]

Globally, there were 87 million unwanted pregnancies in 2005, of those 46 million resorted to abortion, of which 18 million were considered unsafe, resulting in 68,000 deaths. The majority of these deaths occurred in the developing world. The United Nations considers these avoidable with access to safe abortion and post-abortion care. While abortion rates have fallen in developed countries, but not in developing countries. Between 2010–2014 there were 35 abortions per 1000 women aged 15–44, a total of 56 million abortions per year.[41] The United nations has prepared recommendations for health care workers to provide more accessible and safe abortion and post-abortion care. An inherent part of post-abortion care involves provision of adequate contraception.[73]
We only included studies that reported on women's health and nutrition outcomes, and excluded studies that were targeted to women but that reported only on health and nutrition outcomes of children (including birth outcomes). We included outcomes for adolescent girls ages 10–19 y, pregnant and lactating women, nonpregnant and nonlactating women of reproductive age (>19 y), and older women. Studies that described interventions targeting a wider age range of adolescent girls (e.g., ages 8–24 y) were also included but adolescent girls aged >19 y were reported in this review as nonpregnant and nonlactating women of reproductive age. Although many adolescents in low- and middle-income countries are married and bearing children, adolescents (10–19 y) as reported in this review reflect girls who are nonpregnant and nonlactating. The few interventions in low- and middle-income countries that target pregnant and lactating adolescents are reported under pregnant and lactating women. A description of the articles included in this review can be found in Supplemental Table 1.
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.
Part of the reason why so many women fail to get the amount of iron they need is because one of the best sources of iron is red meat (especially liver) which also contains high levels of saturated fat. While leafy green vegetables and beans are also good sources of iron—and don’t contain high levels saturated fat—the iron from plant foods is different to the iron from animal sources, and not absorbed as well by the body. Other foods rich in iron include poultry, seafood, dried fruit such as raisins and apricots, and iron-fortified cereals, breads, and pastas.

Something else to remember: an estimated 90 to 95 percent of dieters who lose weight regain all or part of it within five years, and the consequences can be even worse than simply being overweight. Those who exercise regularly as part of a weight loss diet and maintenance program are more likely to keep the weight off. Also note that an overly restrictive diet can lead to more overeating, a natural reaction to food deprivation.

Calcium: For adult women aged 19-50, the USDA recommended daily allowance is 1,000 mg/day. For women over 50, the recommended daily allowance is 1,200 mg/day. Good sources of calcium include dairy products, leafy green vegetables, certain fish, grains, tofu, cabbage, and summer squash. Your body cannot take in more than 500 mg at any one time and there’s no benefit to exceeding the recommended daily amount.
Low-fat diets also can help you lose weight.16 But the amount of weight lost is usually small. You can lose weight and lower your risk for heart disease and stroke if you follow an overall healthy pattern of eating that includes more fruits, vegetables, whole grains and beans that are high in fiber, nuts, low-fat dairy and fish, in addition to staying away from trans fat and saturated fat.
Globally, women's access to health care remains a challenge, both in developing and developed countries. In the United States, before the Affordable Health Care Act came into effect, 25% of women of child-bearing age lacked health insurance.[176] In the absence of adequate insurance, women are likely to avoid important steps to self care such as routine physical examination, screening and prevention testing, and prenatal care. The situation is aggravated by the fact that women living below the poverty line are at greater risk of unplanned pregnancy, unplanned delivery and elective abortion. Added to the financial burden in this group are poor educational achievement, lack of transportation, inflexible work schedules and difficulty obtaining child care, all of which function to create barriers to accessing health care. These problems are much worse in developing countries. Under 50% of childbirths in these countries are assisted by healthcare providers (e.g. midwives, nurses, doctors) which accounts for higher rates of maternal death, up to 1:1,000 live births. This is despite the WHO setting standards, such as a minimum of four antenatal visits.[177] A lack of healthcare providers, facilities, and resources such as formularies all contribute to high levels of morbidity amongst women from avoidable conditions such as obstetrical fistulae, sexually transmitted diseases and cervical cancer.[6]
