According to North American Menopause Society (2000), the average age for the onset of perimenopause is 47.5 years and natural menopause occurs at the age of 51.4 years in western women. In rural North India, Singh and Arora (2005) found that the average age at menopause is 44.1 years. There were many studies reported the mean age of menopause between 45 to 55 years. Quazi (2006) reported it as 50 years. Dhillon Singh, Hamid and Mahmood (2001) document it as 49.4 + 3.4 years. Chim, Tan, Ang, Chew, Chowg and saw (2002), in their study mentioned as average range of 40 to 59 years with the mean of 49 years.
Young kin & Davis, 2004, in normal menstrual cycle, rising levels of follicular stimulating hormone stimulates the developing dominant follicle to secrete increased amount of estradiol. The increased level of estradiol as well as inhibition from the granulose cells exerts a negative feedback on hypothalamus and the result is decreased in follicular stimulating hormone. After menopause, there is an increased FSH because of reduction in pituitary gonadotropin inhibition of estrogen and progesterone. This change in ovarian steroid production is often gradual, resulting in anovulatory bleeding patterns. Eventually, the ovaries are unable to respond to FSH and LH and the level of gonadotropin hyperactivity stabilizes, gonadotropin levels never return to pre menopausal levels.
Immediate changes of menopause are hot flushes, causing flushes in the chest, face, neck and back, insomnia, mild to moderate depression, bone, joint, muscle aches, swelling, heart beat fluctuations, headache, vagina dryness and increased swelling (Smith, 2002).
Avoidance of caffeine, smoking, wearing cotton clothes is the measures for hot flushes. Exercising regularly in the morning or early evening, doing quiet activity just before the bedtime, sleeping in a comfortable environment, avoidance of sleeping medications, limited food intake prior to sleep are the measures for sleep problems and night sweats. Consuming calcium contained food items to minimize the joint and back discomforts. Stress reduction techniques are helpful for the psychological problems. Seeking medical help are for the sexual and urinary problems. These are all some of the non-pharmacological measures for the menopausal symptoms (Young kin & Davis, 2004).
REVIEW RELATED TO STUDIES ON QUALITY OF LIFE OF POSTMENOPAUSAL WOMEN
Rita Luoto (2009) menopausal health is important since this stage of life is not to be avoided. A recent article in BMC Women’s Health from the Estonian Postmenopausal Hormone Therapy trial has concluded that quality of life is not related to hormonal therapy use. The commentary article discusses this finding and considers other factors related to symptoms and quality of life during menopause. Important factors known to affect hot flushes and quality of life are smoking and high body weight. Since both these factors are modifiable, menopause is a suitable area for health promotion. However, evidence concerning lifestyle changes in symptom relief or increase of quality of life is weak. More trials in this area are needed before women may consider non-pharmacological treatment of symptoms as a reliable option for menopausal symptom cure
Jones G L, Sutton A (2009) had done a study to assess the quality of life in obese postmenopausal women. The aim of this review was to identify the ways in which obesity affects the health-related quality of life of postmenopausal women. This was considered important because a growing body of literature has identified obesity as a significant predictor for a poor psychological wellbeing and negative HRQoL, particularly in women, and because during the transition through the menopause women tend to accumulate more body weight. After searching eight electronic databases, only nine papers appeared meaningful. Although a meta-analysis was not possible, we found that a body mass index >30 kg/m2 was associated with a poor HRQoL in postmenopausal women; particularly in the areas associated with physical functioning, energy and vitality, and health perceptions. Thus, clinical management of obese postmenopausal women should focus on weight reduction and exercise in an attempt to improve wellbeing in these areas.
Kevan Richard (2009) conducted a study to assess the quality of sexual life and menopause. The importance of female sexual fulfillment is increasingly recognized in today’s society. Women’s sexual lives continue well into the menopausal years and beyond; however, the impact of menopause on the quality of that sexual life has not been comprehensively studied in the medical literature. This review attempts to clarify the impact of the physiological, psychological and psychosocial changes occurring at midlife that may affect women’s quality of sexual life. Pharmaceutical and psychological interventions that may assist in improving the quality of sexual life of menopausal women are discussed. Contrary to popular expectation, there is a substantial prevalence of sexual activity among middle-aged women, and the majority of middle-aged women express satisfaction with the quality of their sexual lives.
Avis N E, Colvin (2009) did a study to assess the changes in health related quality of life during the time of menopausal transition.

After one year small but significant improvements were observed in three of nine components of the women’s health questionnaire for those taking combined HRT compared with those taking placebo. Hot flushes were experienced in the combined HRT and placebo groups by 30% and 29% at trial entry and 9% and 25% at one year, respectively. No significant differences in other menopausal symptoms, depression, or overall quality of life were observed at one year. Combined HRT started many years after the menopause can improve health related quality of life.

Jennifer R. Clarkson (2002) did a study to investigate the health-related quality of life in African-American and white obese women. Participants were 145 obese women 87 premenopausal and 58 postmenopausal, who completed the Medical Outcomes Study short form, the Brief Symptom Inventory, the Life Distress Inventory, the Satisfaction with Life Scale, and the Rosenberg Self-Esteem Scale before entering a weight-loss study. The mean age of the subjects was 46.3. Menopausal status had a significant effect on HR-QOL; with premenopausal women being more distressed having more limitations in social activity and having less vitality than the postmenopausal women. This was especially true in the AA women. These data show no difference in HR-QOL between AA and W obese women and suggest that menopausal status may have an impact on HR-QOL, especially in AA women.
