Even if you are the most independent exerciser around, give a group fitness class a shot at least once a week—you may find that you enjoy it more than sweating solo. “Happiness and health are shared through social connectedness and closeness,” says Greg Chertok, director of sport psychology at the Physical Medicine and Rehabilitation Center in New Jersey. “Geography and proximity are predictors of how contagious emotions can be, and this may translate into an athletic environment too.” Sign up for Bikram, CrossFit, spin, or Zumba, and you could find yourself—gasp!—smiling at the gym thanks to your classmates.
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.
Women, as we age, are also more susceptible to the breakdown of our bones, which may result in osteoporosis over time. Genetically, women have a particularly high risk of osteoporosis compared to men, so it’s recommended that women monitor their calcium intake to be sure they’re getting enough. Weight training is another great way (and my favorite!) to build bone density, which is another great reason you should hit the weights!
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]
In 2000, the United Nations created Millennium Development Goal (MDG) 5[43] to improve maternal health.[44] Target 5A sought to reduce maternal mortality by three quarters from 1990 to 2015, using two indicators, 5.1 the MMR and 5.2 the proportion of deliveries attended by skilled health personnel (physician, nurse or midwife). Early reports indicated MDG 5 had made the least progress of all MDGs.[45][46] By the target date of 2015 the MMR had only declined by 45%, from 380 to 210, most of which occurred after 2000. However this improvement occurred across all regions, but the highest MMRs were still in Africa and Asia, although South Asia witnessed the largest fall, from 530 to 190 (64%). The smallest decline was seen in the developed countries, from 26 to 16 (37%). In terms of assisted births, this proportion had risen globally from 59 to 71%. Although the numbers were similar for both developed and developing regions, there were wide variations in the latter from 52% in South Asia to 100% in East Asia. The risks of dying in pregnancy in developing countries remains fourteen times higher than in developed countries, but in Sub-Saharan Africa, where the MMR is highest, the risk is 175 times higher.[39] In setting the MDG targets, skilled assisted birth was considered a key strategy, but also an indicator of access to care and closely reflect mortality rates. There are also marked differences within regions with a 31% lower rate in rural areas of developing countries (56 vs. 87%), yet there is no difference in East Asia but a 52% difference in Central Africa (32 vs. 84%).[37] With the completion of the MDG campaign in 2015, new targets are being set for 2030 under the Sustainable Development Goals campaign.[47][48] Maternal health is placed under Goal 3, Health, with the target being to reduce the global maternal mortality ratio to less than 70.[49] Amongst tools being developed to meet these targets is the WHO Safe Childbirth Checklist.[50]
Consult your health care professional. Women of childbearing age may want to consider taking folic acid supplements to reduce the risk of having a pregnancy affected with neural tube defects. Many women and teenage girls don't get enough calcium or vitamin D, both of which are critical to healthy bones and avoiding osteoporosis. Some people with diabetes appear to benefit from chromium. Vegetarians, especially vegans, may want to consider supplements to obtain nutrients they aren't getting from animal products.

For this comprehensive narrative review, we evaluated both nutrition-specific and nutrition-sensitive interventions. Nutrition-specific approaches are those that address the immediate determinants of nutrition (e.g., food and nutrient intake, diet-related practices and behaviors, disease, etc.), whereas nutrition-sensitive approaches are those that address the underlying determinants of nutrition (e.g., food security, access to resources, safe and hygienic environments, adequate health services, etc.) (5, 12). We evaluated the following nutrition-specific interventions described by Bhutta et al. (13, 14): nutrition counseling and education, micronutrient supplementation and fortification, protein and energy supplementation, and lipid-based supplementation. We also included the following nutrition-sensitive approaches described by Ruel and Alderman (5) and Bhutta et al. (14): health care; family planning; water, sanitation, and hygiene (WASH); empowerment; income-generation; education; and social protection. For each intervention, we 1) described the scale and coverage of the intervention, when available; 2) summarized the evidence of effectiveness for women's health and nutrition outcomes; and 3) described and evaluated the target population and delivery platforms, as described in the published articles and as summarized in Table 1. The delivery of interventions included the physical platforms, as well as the adherence and the implementation challenges of the different interventions.
