Chronic Pelvic Pain in Women in New Zealand: Comparative Well-Being, Comorbidity, and Impact on Work and Other Activities
This article reports the findings of a population -based study in New Zeal and that investigated comparative well-being , comorbidity , and the impact of chronic pelvic pain ( CPP ) on activities . Chronic pelvic pain was defined as lower abdominal pain that is associated with neither the menstrual cycle nor sexual activity . A postal question naire was administered to a r and om sample result ing in a study group of 1,160 . The negative impact of CPP on women 's general well-being is significant . They were more likely than women without CPP to have other long-st and ing illnesses , other unspecified conditions involving pain or fatigue , and sleep patterns were more seriously disturbed . Pain restricted their activities . Comparisons with the limited data available from other studies are made
