Osteoporosis and genetic influence: a three-generation study.

We have studied 27 triads of mother, daughter and grandmother for possible genetic influence on distal and proximal forearm bone density, measured by single photon absorptiometry. We found a significant correlation of bone density at the proximal forearm between the mothers and grandmothers (r = 0.499, P < 0.01). There was also a weak correlation between proximal forearm bone densities of mothers and daughters (r = 0.327, P < 0.1). Significant correlations were found between the three generations for grip strength, pedometry, height and triceps skinfold thickness. There was also significant correlation between mother and grandmother for alcohol intake. There was no correlation for contraceptive pill use, smoking, dietary calcium intake, body weight or body mass index. The study concludes that, although there are similarities in bone mineral content between the three generations, genetic factors cannot be conclusively proven to be the major determinant of bone density. Lifestyle and environmental factors may have a bearing on achieving the peak bone mass and subsequent development of osteoporosis.

Determinants of forearm bone density in premenopausal women: a study in one general practice.

Predictors of distal and proximal forearm bone density, measured by photon absorbtiometry, were investigated in 248 premenopausal women aged 39-56 years. Only one strong predictor of lower bone density was found--history of previous fracture at any site (P less than 0.001). Two other factors showed a weaker association with density, but only at the distal site--history of diuretic use showed a positive association (P less than 0.02) whereas alkaline phosphatase level was inversely correlated with density (P less than 0.01). Other factors were not significant predictors: these included age, calcium intake, level of exercise, anthropometric measures of obesity, serum calcium level, parity, lactation history, a menopausal symptom history, use of the contraceptive pill, smoking and alcohol intake. These results contrast with the far stronger predictors found for postmenopausal women and suggest that genetic endowment rather than lifestyle may be the major determinant of bone density before the menopause.

Death certification by British doctors: a demographic analysis.

Regional differences in mortality from cardiovascular diseases, respiratory diseases, strokes, and other causes have been observed in England and Wales. To determine to what extent the death certification practices of doctors influence these variations, we surveyed 123 British general practitioners and housemen. Each doctor completed death certificates based on fictitious case histories. We found that diagnostic groupings did not vary significantly according to the doctors' region, type of practice, place of medical training, sex, or year of qualification. Doctors qualifying before 1955, however, appeared more inclined than their younger colleagues to list stomach cancer on the death certificate.

Women's attitudes to screening for neural tube defects.

The attitudes of 2254 pregnant and 262 other women to serum alpha-fetoprotein (AFP) screening for neural tube defects (NTDs) were investigated, the former by interview and the latter by questionnaires to which 228 replies were received. Over 97 per cent of the pregnant women wanted to be included in such a screening programme. Ninety-six per cent of other women who completed the questionnaire were in favour of national screening for NTDs but 14 per cent of them were uncertain about the action they would take if the test were positive.

Establishment of two group practice centres by conversion of existing houses.

A practice of five (later six) doctors established their own group practice centre by purchase and conversion of an existing house. Later a second, smaller centre was established in the same way to replace an existing branch surgery.The planning, financing, and execution of these projects is described.

Climacteric symptoms in healthy middle-aged women.

The incidence of climacteric symptoms was determined in 247 healthy premenopausal women in a community setting. These volunteers had been recruited to a longitudinal study of bone density. Of these subjects, 46 ceased to menstruate during the study, and in this subgroup symptoms were compared before and after cessation of menstruation. Only hot flushes increased after cessation of menstruation in the longitudinal study and showed age correlation in the cross-sectional study. Hot flushes thus emerged as a true menopausal symptom. Although evidence for this is weaker, cold sweats and suffocation seem likely to be genuinely menopausal. Breast discomfort and the four mood symptoms of irritability, excitability, depression and poor concentration improved after cessation of menstruation, and this study gives no support for their being part of the menopausal syndrome; it suggests that these symptoms are more likely to be related to menstruation than to the menopause.
