Self-rated Health in Middle-aged Women: Associations with Sense of Coherence and Socioeconomic and Health-related Factors

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.

The women's health in the Lund area (WHILA) study--an overview

The Women's Health in the Lund Area (WHILA) study invited all women (n=10,766) living in the Lund area of Southern Sweden by 1995, who were born between 1935 and 1945. The health screening program included a postal validated questionnaire concerning medical history, drug treatment, family history of diabetes and hypertension, menopausal status, smoking and alcohol habits, education, household, and working status, physical activity, quality of life as well as subjective physical and mental symptoms. The screening consisted of a routine physical examination with standardized blood pressure measurements, bone densitometry and an extended laboratory examination. A link with the mammography registry was established. Based on menopausal status, the population was divided in three subgroups; premenopausal (PM), postmenopausal with hormone replacement therapy (PMT), and postmenopausal without hormone replacement therapy (PM0). Menopause was defined as a bleed-free interval of at least 12 months. Of 10,766 women, 6917 (64.2%) had complete data sets. A number of observational analyses were carried out based on the screening data at baseline, to be followed by long-term follow-up analyses based on national register linkages that are currently being started.

Coeliac disease-specific tissue transglutaminase autoantibodies are associated with osteoporosis and related fractures in middle-aged women

OBJECTIVE

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.

MATERIAL AND METHODS

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.

RESULTS

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).

CONCLUSIONS

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.

Obese women and the relation between cardiovascular risk profile and hormone therapy, glucose tolerance, and psychosocial conditions

OBJECTIVE

To evaluate the relation between cardiovascular disease (CVD) risk factors and hormone therapy, serum hormone levels, glucose tolerance, and psychosocial and psychological conditions in subjectively healthy obese female subjects.

RESEARCH DESIGN AND METHODS

The study included 606 women, aged 50-64 years, with BMI 30-40 kg/m(2) and no history of cardiovascular or other severe diseases. One group with a CVD risk profile (n = 473) (i.e., cholesterol >7.0 mmol/l, HDL cholesterol <1.2 mmol/l, triglycerides >2.0 mmol/l, systolic or diastolic blood pressure >140/90 mmHg, or waist-to-hip ratio >0.85) was compared with women without such risk (n = 133). Steroid hormones, leptin, insulin, and oral glucose tolerance tests (OGTTs) were analyzed. A subgroup of women with baseline impaired glucose tolerance (IGT) completed a 2.5-year follow-up OGTT.

RESULTS

Fewer obese postmenopausal women with CVD risk had ever used hormone therapy (odds ratio 0.24 [95% CI 0.07-0.75]), after multivariate adjustments. Furthermore, women with CVD risk had a higher testosterone index (1.07 [1.01-1.13]) and more had insulin resistance (1.04 [1.00-1.08]) and IGT (2.92 [1.50-5.69]), while OGTT was similar at follow-up. No differences were observed regarding family history or lifestyle, except that fewer women with CVD risk consumed fruits, boiled vegetables, or whole-grain cereals. More women with CVD risk lived alone (3.26 [1.28-8.31]) and had more mental problems (1.16 [1.05-1.28]).

CONCLUSIONS

Previously healthy obese women with a CVD risk profile seemed to have a high risk of diabetes, as well as psychosocial or psychological problems. Hormone therapy was associated with reduced CVD risk. Obesity's growing burden on society makes it more important to further target individuals that are at greatest risk of future health hazards.

Colorectal cancer in middle-aged women in relation to hormonal status: a report from the Women's Health in the Lund Area (WHILA) study

OBJECTIVE

To delineate a perceived association of estradiol versus estradiol plus norethisterone hormone therapy on the prevalence of colorectal cancer in postmenopausal women.

METHODS

The Women's Health in the Lund Area (WHILA) project covers 10,766 women aged 50-60 years, living in the Lund area, Sweden. Out of this population, 6908 (64%) women completed questionnaires, underwent physical and laboratory assessments and had self-reported information regarding colorectal cancer. Four hundred and twenty-two (6%) were premenopausal (PM), 3600 (52%) were postmenopausal without hormone therapy (PM0), 2452 (36%) were postmenopausal with combined hormone therapy (PMT-HT) and 364 (5%) were postmenopausal with estrogen monotherapy (PMT-E).

RESULTS

There were 21 cases of colorectal cancer (0.3%), one in the PM group, 16 in the PM0 group, two in the PMT-HT group and another two in the PMT-E group. Colorectal cancer prevalence was lower in the PMT-HT than in the PM0 group (odds ratio (OR) = 0.18, 95% confidence interval (CI) = 0.04-0.80). However, for the PMT-E group, the OR (95% CI) was 1.02 (0.86-1.20). There was a positive association between low physical activity (p = 0.04), low parity (p = 0.02) and risk of colorectal cancer.

CONCLUSION

Combined hormone therapy seemed to be associated with a lower risk of colorectal cancer in postmenopausal women in contrast to estrogen monotherapy. Hence the progestin might have a protective role.

The hysterectomized woman

OBJECTIVE

To delineate the health profile of hysterectomized women and to assess whether women who have undergone hysterectomy have a different health profile even before surgery.

MATERIAL AND METHODS

The WHILA project covers all women (n = 10,766) aged 50-60, living in the Lund area and are based on questionnaires and personal interviews tied to laboratory examinations.

RESULTS

6917 women (64.2%) had complete questionnaires and laboratory tests, 800 were hysterectomized (11.6%). Logistic regression analysis revealed that hysterectomized women had more "dizziness" 1.40 (1.19-1.66), "nervous problems" 1.29 (1.07-1.56), "backache" 1.37 (1.16-1.62), "joint problems" 1.29 (1.09-1.52), "eye problem" 1.20 (1.02-1.42) and "headache" 1.17 (1.00-1.37). For both somatic (5.22 versus 4.49 mean value, p < 0.001) and psychological (4.19 versus 3.86 mean value, p = 0.002) symptoms, the number was higher in hysterectomized women. Logistic regression analysis revealed that among hysterectomized women university education was less common odds ratios 0.73 (95% confidence interval 0.58-0.91) as well as working full time 0.76 (0.62-0.93). A higher body weight at the age 25, 1.01 (1.001-1.02) as well as a weight gain of more than 5 kg during the last 5 years 1.27 (1.07-1.50), elevation of serum triglycerides 1.29 (1.16-1.44), high-density (HDL) 1.44 (1.14-1.80) and low-density lipoprotein (LDL) cholesterol 1.11 (1.02-1.21) as well as the bone density 1.08 (1.00-1.17). Hysterectomized women had a lower age at giving first birth (p < 0.001), shorter interval between menstrual periods (p < or = 0.001) and less frequent amenorrhic episodes (p < 0.05). The hysterectomized women used IUD to a lesser extent (p < 0.05) but used hormone therapy (HT) (p < 0.001) and utilized health care services (p < 0.001) more often.

CONCLUSIONS

Long after surgery, several somatic and psychological symptoms were still more common in hysterectomized women. A low frequency of amenorrhic episodes and lower age at giving first birth, concomitant with a higher body weight already at age 25 may imply that women who end up hysterectomized have a specific health profile long before as well as long after surgery.

Socio-demographic and psychosocial factors are associated with features of the metabolic syndrome. The Women's Health in the Lund Area (WHILA) study

AIM

The aim was to analyse any associations between socio-demographic and psychosocial factors and different features of the metabolic syndrome in a geographically well-defined population of middle-aged women.

METHODS

A population of 10 766 Caucasian women aged 50-59 years was investigated regarding biological and socio-demographic conditions, physical activity, dietary habits, aspects of quality of life, and subjective physical and mental symptoms. The screening instrument was used to discriminate subjects as positive or negative on one or more of a total of eight variables considered to be linked to the metabolic syndrome. The cut-off values for positive screening were non-fasting capillary blood glucose >/= 8.0 mmol/l and serum triglycerides >/= 2.3 mmo/l, BMI >/= 30 kg/m2, WHR >/= 0.90, blood pressure >/= 160 and/or 95 mmHg, a family history of diabetes, and pharmacological treatment for hypertension or hyperlipidaemia.

RESULTS

Altogether 6805 women (63.2%) participated: 3535 with positive and 3270 with negative screening. Multiple logistic regression analyses showed that comprehensive (OR 1.62, 95% CI 1.41-1.87) and upper secondary (1.40, 1.24-1.57) school, low physical quality of life (1.41, 1.23-1.61) and high sum of subjective physical symptoms (1.06, 1.04-1.08) were positively associated with one or more features of the metabolic syndrome, while high leisure-time exercise and healthy diet (0.84, 0.71-0.99), and low (</= 83 g/week) (0.71, 0.63-0.81) and moderate (84-167 g/week) (0.78, 0.65-0.93) alcohol consumption were negatively associated.

CONCLUSIONS

To identify middle-aged women with cardiovascular risk factors and high risk for diabetes, it is important to consider not only biological, but also socio-demographic and psychosocial conditions.
