Clustering of risk variables associated with the metabolic syndrome (MS) begins before the onset of menopause. However, studies of the factors underlying this clustering have focused on only postmenopausal women.
The present community-based, cross-sectional investigation was aimed at identifying the principal components of risk variables associated with the metabolic syndrome in pre- and postmenopausal Bengalee women.
A total of 200 (100 premenopausal women; mean age = 40.2 +/- 6.5 years and 100 postmenopausal women; mean age = 55.4 +/- 5.2 years) healthy adult (30 years and older) Bengalee women took part in the study. Obesity measures, metabolic profiles and blood pressures were taken. Principal components factor analysis (PCFA) was used to identify the principal components of the MS.
There were significant differences between the two groups for obesity measures, metabolic profiles and blood pressure, even after adjusting for age. PCFA revealed three uncorrelated factors with a 67.1% explanation in the premenopausal women. Four factors, with overlapping between the first three factors, and a 73% explanation were evident for the postmenopausal women.
Since more than one factor was identified, more than one physiological mechanism could have accounted for clustering of the risk variables associated with the MS and this would warrant early intervention, well before the menopause.
与代谢综合征(MS)相关的风险变量聚集在绝经前就已开始。然而,对这种聚集背后因素的研究仅集中在绝经后女性。
本次基于社区的横断面调查旨在确定绝经前后孟加拉女性中与代谢综合征相关的风险变量的主要成分。
共有200名(100名绝经前女性;平均年龄 = 40.2 +/- 6.5岁和100名绝经后女性;平均年龄 = 55.4 +/- 5.2岁)30岁及以上的健康成年孟加拉女性参与了该研究。测量了肥胖指标、代谢状况和血压。采用主成分因子分析(PCFA)来确定代谢综合征的主要成分。
即使在调整年龄后,两组在肥胖指标、代谢状况和血压方面仍存在显著差异。PCFA显示绝经前女性中有三个不相关的因子,解释率为67.1%。绝经后女性有四个因子,前三个因子有重叠,解释率为73%。
由于识别出了不止一个因子,可能有不止一种生理机制导致了与代谢综合征相关的风险变量聚集,这将需要在绝经前很早就进行干预。
