Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialPsychosocial influences on older adults' interest in participating in bowel cancer screening.
As part of a multicenter, randomized controlled trial of the efficacy of flexible sigmoidoscopy for the prevention of bowel cancer, an investigation of the predictors of screening interest was carried out in a subsample of older adults. ⋯ This community study in older adults showed a high level of interest in participating in screening. The large sample size provided the opportunity to test the value of the HBM model and to examine mediation of demographic and health variables. The HBM proved to be a good model of screening interest. These results further our understanding of the decision processes in participating in cancer screening and point to directions to increase the level of participation in community samples.

Multicenter Study Comparative Study Clinical TrialSmokers ages 50+: who gets physician advice to quit?
Smoking-related morbidity and mortality, and benefits associated with quitting, extend across the life span. Health care provider interventions enhance quitting. The present study examined perceived influence of physician advice to quit and characteristics of subjects receiving this advice. ⋯ Midlife and older smokers reacted generally favorably to physician advice to quit. Physicians were more likely to advise patients with commonly recognized smoking-related diseases. Discrepancies were noted in advice given to sicker vs healthier patients. Additional physician training in less commonly recognized smoking-related illnesses, intervening with healthier patients to prevent disease, and enhancing patients' confidence in quitting may improve outcomes.

Randomized Controlled Trial Comparative Study Clinical TrialHypocholesterolemic effect of soymilk supplementation with usual diet in premenopausal normolipidemic Japanese women.
The hypocholesterolemic effect of soy protein concentrates on normolipidemic subjects still remains unclear. Our objective is to assess the effect of soymilk supplementation, a whole soy product, with usual diet on serum lipids in normolipidemic subjects. ⋯ Our results suggest the hypocholesterolemic effect of soymilk, a traditional whole soy product, in Asian countries in normolipidemic subjects.
