This study investigated the efficacy of a behavioral weight control program in 36 black female adolescents with a mean age of 14.0 years, weight of 95.0 kg, and height of 163.2 cm. All subjects(More)

To examine the relation between lactation and bone mineral density, we conducted a cross-sectional study among white, nonsmoking, perimenopausal women age 40-54. Three hundred fifty-two women completed a questionnaire covering medical and reproductive histories, physical activity, and diet. We measured the bone density of lumbar vertebrae 2-4 with dual(More)
OBJECTIVES This paper examines differences between joiners and nonjoiners of a voluntary smokers' registry.

A theory-based HIV risk-reduction intervention was developed for HIV-positive men with haemophilia and their HIV-negative female romantic partners. The intervention was based on Prochaska and DiClemente's Transtheoretical Model which describes behaviour change as an incremental, stage-based process. The intervention targeted both communication about safer(More)
Highly luminescent semiconductor quantum dots have been synthesized in porous materials with ultraviolet and x-ray lithography. For this, the pore-filling solvent of silica hydrogels is exchanged with an aqueous solution of a group II metal ion together with a chalcogenide precursor such as 2-mercaptoethanol, thioacetamide or selenourea. The chalcogenide(More)
When retinal disparity exceeds the limits for fusion, the resulting images are perceived as diplopic. In a stereo test that allowed comparison of crossed and uncrossed disparity sensitivities, 74% of the subjects perceived convergent disparities more readily than divergent disparities. This asymmetric sensitivity to disparity did not appear to be related to(More)
Determinants of safer sexual behaviors among HIV-infected adult men with hemophilia were examined. A model was proposed that personal adjustment, communication skills, self-efficacy, and perceived advantages of condom use would influence safer sex practices. The model was tested with 181 men with hemophilia and HIV infection from 27 hemophilia treatment(More)
