WASH interventions were typically community-based. WASH interventions were delivered to households and communities through community mobilization, mass media, home visits, and infrastructural development (126, 130, 136–138). There were some examples of facility-based delivery of WASH interventions, such as in health clinics and schools (139, 140); however, this was not representative of the majority of delivery platform coverage. Health clinic delivery platforms had limited reach, often targeting pregnant women and women with young children. In an evaluation of WASH interventions delivered in India (141), more demanding behavioral practices, such as handwashing and consistent use of latrines, required more intense contact (e.g., multiple home visits) than less intense interventions, such as sweeping of courtyards, that could be effectively delivered in small group meetings such as those in health clinics and community centers. More research is needed to evaluate the benefits and barriers of different delivery platforms for women across the life course.
Most experts recommend 1,300 mg of calcium a day for girls aged 9 through 19. Natural sources of calcium, such as low-fat dairy products, are the smartest choice, because they also contain vitamin D and protein, both required for calcium absorption. Milk, yogurt, and cheese contribute most of the calcium in our diets. Some vegetables are also good sources, including broccoli, kale, and Chinese cabbage. Many foods are supplemented with calcium, including some brands of orange juice and tofu. The daily intake for Vitamin D is 600 IU per day for most children and healthy adults.
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), Women's Health Initiative and Black Women's Health Study.
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.
Dietary fiber is found in plant foods like whole-grain breads and cereals, beans and peas, and other vegetables and fruits. At least one study suggests that women who eat high amounts of fiber (especially in cereal) may have a lower risk for heart disease. High-fiber intake is also associated with lower cholesterol, reduced cancer risk and improved bowel function. And one long-term study found that middle-aged women with a high dietary fiber intake gained less weight over time than women who ate more refined carbohydrates, like white bread and pasta.
Micronutrient supplementation programs for vitamin A, iron and folic acid, calcium, zinc, and multiple micronutrients effectively impacted the micronutrient status of pregnant and lactating women, as well as women of reproductive age and adolescent girls (13, 14, 33, 35–48). Interventions making use of multiple micronutrients were more effective at changing plasma micronutrient concentrations than interventions focused solely on 1 nutrient alone (38, 42). In countries with comprehensive programs for iron supplementation during pregnancy, anemia prevalence dropped (1, 49). Positive health impacts of supplementation were most notable among pregnant women who were deficient and at risk of low intake (43, 50). However, there were some studies that showed inconsistent or limited evidence for the effectiveness of supplementation on other maternal health outcomes (31, 51–58).
Calories. Most times, women need fewer calories. That’s because women naturally have less muscle, more body fat, and are usually smaller. On average, adult women need between 1,600 and 2,400 calories a day. Women who are more physically active may need more calories. Find out how many calories you need each day, based on your age, height, weight, and activity level.
Calcium: Although some bone loss is inevitable with age, women can slow the process by getting enough calcium and vitamin D. Women between the ages of 50 and 70 need 1200 mg of calcium and 600 IU of Vitamin D a day. Women older than 70 require 1200 mg of calcium and 800 IU of Vitamin D a day. Because the skin becomes less efficient at converting sunlight to vitamin D as we age, older women may need more vitamin D in the form of supplements. Talk to your doctor.
Everyone seems to have food allergies these days, but in fact, such allergies are rare. According to the National Institute of Allergy and Infectious Diseases, while one in three adults think they have a food allergy or modify their family's diet, only about four percent do. A food allergy is an abnormal immune-system response to certain foods (most commonly, fish, shellfish, peanuts, other nuts and eggs). Symptoms can include hives, rashes, nasal congestion, nausea, diarrhea and gas. However, symptoms of food intolerance—such as intestinal distress—may mimic those of a food allergy. You may want to talk to an allergist about diagnosis and treatment. Whether you have food allergies or intolerance, you will need to develop a diet that fits your needs and avoids foods that trigger a reaction.
