In 2013 about 289,000 women (800 per day) in the world died due to pregnancy-related causes, with large differences between developed and developing countries. Maternal mortality in western nations had been steadily falling, and forms the subject of annual reports and reviews. Yet, between 1987 and 2011, maternal mortality in the United States rose from 7.2 to 17.8 deaths per 100,000 live births, this is reflected in the Maternal Mortality Ratio (MMR). By contrast rates as high as 1,000 per birth are reported in the rest of the world, with the highest rates in Sub-Saharan Africa and South Asia, which account for 86% of such deaths. These deaths are rarely investigated, yet the World Health Organization considers that 99% of these deaths, the majority of which occur within 24 hours of childbirth, are preventable if the appropriate infrastructure, training, and facilities were in place. In these resource-poor countries, maternal health is further eroded by poverty and adverse economic factors which impact the roads, health care facilities, equipment and supplies in addition to limited skilled personnel. Other problems include cultural attitudes towards sexuality, contraception, child marriage, home birth and the ability to recognise medical emergencies. The direct causes of these maternal deaths are hemorrhage, eclampsia, obstructed labor, sepsis and unskilled abortion. In addition malaria and AIDS complicate pregnancy. In the period 2003–2009 hemorrhage was the leading cause of death, accounting for 27% of deaths in developing countries and 16% in developed countries.
In low- and middle-income countries, health care services often respond to acute health needs and many focus on maternal–child health (105, 106, 110, 112). The use of preventative care is limited, and there are concerns about the capacity of health systems to address noncommunicable diseases, such as diabetes, in low- and middle-income settings (108, 112). This has implications for the reach of integrated health care interventions across the life course. Maternal and reproductive health care is often sought by women when they are pregnant and in the early years of their children's lives (3, 113). Even so, many women visit health facilities late in their pregnancy or not at all (114–116). For adolescents and adult women, care is often not sought until they are sick (3, 117, 118). This is problematic for older women, in particular, as screening and treatment for age-related health issues, such as diabetes, cancer, and hypertension, require access to preventative health care services (3).
Women's life expectancy is greater than that of men, and they have lower death rates throughout life, regardless of race and geographic region. Historically though, women had higher rates of mortality, primarily from maternal deaths (death in childbirth). In industrialised countries, particularly the most advanced, the gender gap narrowed and was reversed following the industrial revolution.  Despite these differences, in many areas of health, women experience earlier and more severe disease, and experience poorer outcomes.
In addition to diet, exercise and other lifestyle factors can also play an important role in bone health. Smoking and drinking too much alcohol can increase your chances of developing osteoporosis, while weight-bearing exercise (such as walking, dancing, yoga, or lifting weights) can lower your risk. Strength or resistance training—using machines, free weights, elastic bands, or your own body weight—can be especially effective in helping to prevent loss of bone mass as you age.
