The World Health Organization (WHO) estimates that 35% of women in the world have experienced physical or sexual violence over their lifetime and that the commonest situation is intimate partner violence. 30% of women in relationships report such experience, and 38% of murders of women are due to intimate partners. These figures may be as high as 70% in some regions. Risk factors include low educational achievement, a parental experience of violence, childhood abuse, gender inequality and cultural attitudes that allow violence to be considered more acceptable.
WASH interventions, such as toilet facilities, access to improved and safe water supply, and hand washing are associated with improved nutrition and health of entire communities (13, 14, 125–128). For women and adolescent girls, WASH interventions were associated with improved menstrual hygiene (126), reduced diarrhea and intestinal worm infections (128–131), and reduced maternal mortality (132). Women and young girls are also more affected by the physical and time burdens of collecting water (126), and harassment and violence associated with inadequate and unsafe toilet facilities (133, 134). Closer water points and sanitation facilities eased these gendered burdens (126, 135). WASH interventions and perceived water availability were associated with less time spent on water-related chores, and improved school attendance, women's empowerment, and self-esteem (126, 135, 136).
Women's health refers to the health of women, which differs from that of men in many unique ways. Women's health is an example of population health, where health is defined by the World Health Organization as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity". Often treated as simply women's reproductive health, many groups argue for a broader definition pertaining to the overall health of women, better expressed as "The health of women". These differences are further exacerbated in developing countries where women, whose health includes both their risks and experiences, are further disadvantaged.
