Waist circumference and dual-energy X-ray absorptiometry measures of overall and central obesity are similarly associated with systemic oxidative stress in women.

Growing evidence suggests that overall and abdominal obesity might lead to oxidative stress (OxS), which, in turn, plays a key role in the pathogenesis of a wide spectrum of diseases. In this study, for the first time, we compared the correlations of indirect, i.e.

Accumulation of central fat correlates with an adverse oxidative balance in non-obese postmenopausal women.

The aim of the present study was to investigate whether accumulation of central fat is correlated with systemic oxidative stress (OxS) in non-obese apparently healthy postmenopausal women. Serum parameters of OxS (hydroperoxides and non-enzymatic antioxidants) along with body fat distribution, as assessed by dual-energy-X-ray absorptiometry (DXA), were evaluated in 134 non-obese postmenopausal women. Multiple regression analysis showed that central (trunk) fat significantly correlated with both markers of OxS independently of confounding factors (i.

Metabolic transitions at menopause: in post-menopausal women the increase in serum uric acid correlates with abdominal adiposity as assessed by DXA.

Objectives: The present study aimed to investigate any associations between parameters of body fat mass distribution and levels of serum uric acid (sUA), a well-documented cardiovascular risk factor, among non-obese women ranging from pre- to post-menopausal status.

Methods: In this cross-sectional population-based study we assessed body fat distribution by dual-energy-X-ray absorptiometry (DXA), and sUA levels in 101 pre- and 134 post-menopausal non-obese apparently healthy women.

Results: Multivariate stepwise regression analysis revealed that sUA was independently associated to the indicators of overall fatness, i.

Bone mass density selectively correlates with serum markers of oxidative damage in post-menopausal women.

Background: Post-menopausal osteoporosis (PO) affecting a large fraction of elderly women, is triggered by the decline in 17β-estradiol (E2) level. Experimental studies in animal models and cell cultures have suggested that the fall in E2 might contribute to developing oxidative stress (OS) which in turn is believed to play an important role in PO pathogenesis. The scarcity of human studies focusing on this issue prompted us to investigate the effects of the reproductive and post-reproductive phase of women's life on OS and bone health.

17β-estradiol levels and oxidative balance in a population of pre-, peri-, and post-menopausal women.

Background: The high incidence of various diseases observed in post-menopausal women has been widely associated to the decline of 17β-estradiol (E2) occurring in correspondence of menopausal transition. One of the mechanisms suggested to explain this link takes into account the ability of E2 to counteract oxidative stress (OS) which is believed to play an important role in several pathogenic processes.

Aim: To investigate whether stages of women's life characterized by different levels of E2 influence OS.

Body mass index is a major determinant of abdominal fat accumulation in pre-, peri- and post-menopausal women.

Objective: To investigate the role of menopause, body mass index (BMI) and aging on body fat distribution in women.

Design: In this population-based cross-sectional study, 335 women (126 in pre-menopause, 75 in peri-menopause and 134 in post-menopause according to Stages of Reproductive Aging Workshop criteria) were evaluated for body mass composition and fat distribution by dual X-ray absorptiometry procedure. A sub-group of 79 women with similar age and BMI was extracted from the sample to examine the relative influence of BMI in body fat distribution.

Oxidative stress, body fat composition, and endocrine status in pre- and postmenopausal women.

Objective: To evaluate the role of menopause on the regional composition and distribution of fat in women and eventual correlations with the oxidative state.

Design: In this observational clinical investigation, 90 women (classified for menopause status according to Stages of Reproductive Aging Workshop criteria) were evaluated for body mass composition and fat distribution by dual-energy x-ray absorptiometry and for oxidative status by determination of serum hydroperoxide levels and residual antioxidant activity.

Results: Total body fat mass increases significantly in postmenopause (P < 0.
