    Notes: Abstract Apparent molal volumes and compressibilities are reported for dilute aqueous solutions of cyclic ethers, simple carbohydrates, and related polyhydroxy compounds. The results for carbohydrates are considered in the light of two theoretical descriptions of such systems, i.e., the semiideal solution approach of Stokes and Robinson, and the McMillan-Mayer theory ty[e of approach as employed by Kozak, Knight, and Kauzmann. It is concluded that neither model is satisfactory, and that for these solutions a specific hydration model, described in more detail in another paper, is more satisfactory.

    Population screening for low bone mineral density: Do non-attenders have a lower risk of osteoporosis? (1994)

    Notes: Abstract Poor compliance may be detrimental to the effectiveness of a screening programme if those at greatest risk of the disease do not attend. Therefore we undertook a study to test whether non-attenders to a screening programme for low bone density, a risk factor for osteoporosis, were at a differential risk of low bone density compared with attenders. Seven hundred and eighty-nine women aged 45–49 years living within 32 km of Aberdeen were selected at random from the Community Health Index and invited to attend for screening for low bone density as a risk of factor for osteoporosis. Attenders and non-attenders were surveyed regarding their risk factors for osteoporosis. Non-attenders were significantly heavier than attenders. In addition, 6 non-attenders who subsequently chose to attend had significantly higher body weight and bone mineral density, at Ward's triangle, than initial attenders. Non-attenders to a screening service for bone density may be at lower risk of developing osteoporosis. Non-attendance, therefore, would not be detrimental to the cost-effectiveness of a screening service for bone density. However, this study indicates there is a potential for response bias in studies of bone density and osteoporosis.
