ABSTRACT The objective of this cross-sectional study was to analyse the influence of biological, socio-demographic, and psychosocial factors and current perimenopausal status on hypertension in a geographically defined population of 10,766 women aged 50-59 years, of whom 6901 attended the study. Altogether 1887 (27.3%) women had hypertension: 996 with drug treatment and 891 diagnosed at the study. In a logistic multiple regression analysis (controlled for age), drug treatment of hyperlipidaemia, family history of hypertension, waist-to-hip ratio, body mass index (BMI) increase > or = 25% during the past 25 years, S-triglycerides, S-cholesterol, education up to comprehensive school, and to upper secondary school, consumption of 84-167 g of alcohol/week, and of > or = 168 g of alcohol/week, were positively associated with hypertension, while high-density lipoprotein cholesterol and current smoking were negatively associated. A significant interaction was found between current smoking and BMI increase, with a lower risk for hypertension among smokers who had increased their BMI > or = 25%. No interaction was found between smoking and alcohol. In conclusion, hypertension was predominantly associated with biological factors, and with heredity for hypertension. Of the socio-demographic factors, only low level of education was associated with hypertension in a comprehensive analysis. Perimenopausal status showed no relation to occurrence of hypertension in the multiple regression analysis. The risk for hypertension increased with moderate and high consumption of alcohol, whereas smoking showed a decreased risk. Among women with weight gain, present smoking remained protective. Although both smoking and hypertension are established risk factors for cardiovascular disease, they seem not to be directly linked, indicating a complexity of mechanisms.

    ABSTRACT: To investigate whether the serological marker for coeliac disease, tissue transglutaminase autoantibody (tTGAb), is associated with decreased bone mass density (BMD) and increased frequency of fractures in middle-aged women screened for osteoporosis. The study comprised 6480 women (mean age 56 years, range 50-64) who answered a number of questionnaires and who underwent dual X-ray absorptiometry of the wrist bone. Serum samples were analysed for tTGAb using radioligand binding assays. A tTGAb level of >4 U/ml was used to determine a positive value and a level of >17 U/ml was used as an alternative discrimination of high levels. A tTGAb level >4 U/ml was found among 90/6480 (1.4%) women and correlated with lower BMD (multiple linear regression coefficient -382.1; 95% CI = - 673.6-90.7, p=0.011) and with fracture frequency (r=0.18, p=0.023). The 59 women with tTGAb levels >or=17 U/ml had a lower BMD (0.41+/-0.08 g/cm(2) versus 0.44+/-0.08 g/cm(2), p=0.001) and a lower T-score (-1.40+/-1.28 versus -0.90+/-1.40, p=0.003) as well as a higher prevalence of osteoporosis (13.4% versus 6.5%, p=0.008) compared with the remaining 6421 women with tTGAb levels <17 U/ml. Furthermore, fracture frequency was more pronounced in women with tTGAb levels >or=17 U/ml, among whom 19/59 (32.2%) had fractures during the study period compared with 1204/6421 (18.8%) among women with tTGAb levels <17 U/ml (p=0.009). High levels of tTGAb indicating coeliac disease are associated with lower BMD and higher fracture frequency in women between 50 and 64 years of age. Osteometry is therefore warranted in middle-aged women detected with tTGAb.

    ABSTRACT: This study aimed to describe and analyse self-rated health in relation to sense of coherence and socioeconomic and health-related factors and to explore the associations between self-rated health and these factors in order to identify health resources and health limitations in a group of healthy middle-aged women. Healthy middle-aged women from a defined geographical area in Southern Sweden ( n =577) answered a postal survey with the sense of coherence scale and questions about socioeconomic and health-related conditions. The results showed that very good/rather good self-rated health was associated with high sense of coherence and good economic situation, and these factors can be seen as a health resource. Poor self-rated health was most strongly associated with perceived symptoms of tension, weak sense of coherence, treatment for depression, treatment for chronic disease, and difficult economic situation, and these factors can be seen as health limitations. In conclusion, only 29% of the women rated their health as very good and 41% of the women had symptoms of tension but they were not sick-listed. It is of major public health interest to improve the understanding of self-rated health and to develop health promotion for women and methods to prevent symptoms of tension and sick-listing.
