Clinical profile of Spanish postmenopausal women with a diagnosis of osteoporosis and risk factors for endometrial pathology, breast cancer, and cardiovascular disease

Population-based norms for the Cervantes-SF short-form questionnaire assessing health-related quality of life in menopause

OBJECTIVES

To develop the population-based norms for the Cervantes-SF scale, which measures the impact of menopause on the health-related quality of life (HRQOL) of women in Spain.

METHODS

We used a sample obtained from representative studies of the Spanish population according to geographic density and autonomous community. This sample was composed of 5,237 non- institutionalized peri- and post-menopausal women, aged 40-75 years. Measures of central tendency, dispersion and percentiles were calculated for the total score and its dimensions, in 11 three-year age categories. Construct validity was analyzed based on a comparison with known groups to confirm the validity of the normative scales.

RESULTS

The norms show a monotonic gradient, with an incremental impact on HRQOL as age increases, as shown by an increase in the total score and each of the dimensions. Fifty percent of women showed that peri-/post-menopausal symptomatology interfered with HRQOL > 39 %, ranging from 25 % (40-44 years) to 47 % (72-75 years). The population norms showed significant differences between groups according to generic HRQOL, number of comorbidities, history of osteoporotic fracture, educational level, and presence of obesity.

CONCLUSIONS

These results support the validity of the population-based norms for the Cervantes-SF scale, a valid instrument for measuring the impact of menopause on HRQOL in Spain. The norms obtained facilitate the interpretation of these scores in clinical practice, research, and health management.

Disability-adjusted-life-years losses in postmenopausal women with osteoporosis: a burden of illness study

BACKGROUND

To estimate the disability-adjusted life years (DALY) in a nationwide representative sample of postmenopausal women with osteoporosis. The effects of drug-based therapy and risk factors for osteoporotic bone fractures on DALY losses were also explored.

METHODS

DALY were estimated based on participant's clinical characteristics and Health-Related Quality-of-Life (HRQoL) data obtained from a cross-sectional, epidemiological one-visit study (the GINERISK study). The study enrolled postmenopausal women (at least 12-months after their last menstrual period) with osteoporosis, above 18-years old, who attended Spanish outpatient Gynaecology clinics. HRQoL was assessed using the generic SF-12v2 questionnaire, which was used to derive disutility values. Mortality rates were extracted from the Spanish national statistics database. Factors explored to be associated with DALY losses were examined using ANOVA, ANCOVA and MANCOVA models.

RESULTS

DALY could be computed in 2,782 (67%) out of 4,157 postmenopausal women, with a mean (95% CI) age of 61.0 (60.7-61.2) years. Overall individual undiscounted DALY per woman were 6.1 (5.9-6.2), resulting to be significantly higher in women with severe osteoporosis with prior bone fracture; 7.8 (7.2-8.4) compared to osteoporotic women [5.8 (5.6-6.0)] or postmenopausal women with a BMD > -2.5 T-score that received a drug-based therapy [6.2 (5.8-6.5)]; F = 27.0 (P < 0.01). Models explaining the variation in the levels of health based on the use of a selective estrogen receptor modulator (SERM) or possession of risk factors for osteoporotic BF were found (P < 0.05).

CONCLUSIONS

DALY losses were considerable amongst postmenopausal women with osteoporosis. Not having a prior bone fracture, being older, using a SERM and having less osteoporotic risk factors were all linked to less DALY losses.

Impact of osteoporosis and bone fracture on health-related quality of life in postmenopausal women

BACKGROUND

Osteoporosis is responsible for fragility fractures, which are associated with decreased physical and social function. The GINERISK study was a cross-sectional epidemiological study conducted in 4157 Spanish postmenopausal women initially diagnosed with osteoporosis according to WHO criteria within the last 2 years.

AIM

The aim of the study was to explore the impact of osteoporosis on health-related quality of life (HRQoL).

METHOD

Menopause-specific and generic HRQoL were assessed, respectively, with the specific Cervantes Scale and the generic SF-12v2 Health Survey. The impact of osteoporosis on HRQoL was ultimately evaluated in 3328 (80.1%) women who had measurements for both bone mineral densitometry (BMD) and HRQoL.

RESULTS

Menopause-specific or generic HRQoL, respectively, were worse in women with current osteoporosis and prior osteoporotic bone fracture (BF) in comparison with current osteoporosis without BF or whose T-score had increased above -2.5 on the BMD after receiving osteoporosis drug therapy. Impaired HRQoL was found both in Spanish postmenopausal female populations and the Spanish general female population. Women with osteoporosis with BF had physical and mental summary component scores in the 20th and 30th percentiles, respectively, of the Spanish general population. Higher risk for cardiovascular death was also associated with greater HRQoL impairment. The use of selective estrogen receptor modulators in women with a BMD T-score ≤ -2.5 was associated with lower impact of osteoporosis on HRQoL, particularly in the domains of physical health and sexuality.

CONCLUSION

The HRQoL analysis results in this study demonstrated a loss of quality of life in postmenopausal women with osteoporosis and confirmed that this loss is greater in women with prior osteoporotic fracture.
