Clinical Trials


  • Cardiovascular Health in Postpartum Women Diagnosed With Excessive Gestational Weight Gain Not Recruiting

    The investigators will test the efficacy of a tailored behavioral lifestyle modification program to support cardiovascular health in postpartum women with excessive gestational weight gain. This program will include a mobile health texting component postpartum to support changes in nutrition and physical activity. The investigators will randomize women into either the control arm (usual care) or the intervention (usual care + mobile health program postpartum). The women will be recruited during their 3rd trimester once they have been identified as gaining too much weight according to the 2009 IOM guidelines during pregnancy.

    Stanford is currently not accepting patients for this trial.

  • Gender Differences in Weight-Related Attitudes and Behaviors Among Overweight and Obese Adults in the United States. American journal of men's health Tsai, S. A., Lv, N., Xiao, L., Ma, J. 2016; 10 (5): 389-398

    Abstract

    Few studies have used nationally representative data to focus specifically on gender differences in weight-related outcomes. This article examines gender differences in weight-related outcomes across the body mass index (BMI) spectrum in overweight and obese adults. Data from the National Health and Nutrition Examination Survey 2009-2010 was analyzed. Weight-related outcomes were accurate weight perception, weight dissatisfaction, attempted weight loss, successful weight loss, and weight loss strategies. Compared with women, overweight and obese men were less likely to have accurate weight perception (odds ratio [OR] = 0.36; 95% confidence interval [CI] = 0.30-0.44), weight dissatisfaction (OR = 0.39; 95% CI = 0.32-0.47), and attempted weight loss (OR = 0.55; 95% CI = 0.48-0.63). The modifying effect of gender on these associations decreased as BMI increased. By BMI 35, the mean probability of women and men to have accurate weight perception and weight dissatisfaction was 90%; attempted weight loss was 60% (women) and 50% (men). At lower BMIs, men had up to 40% less probability than women for these weight loss outcomes. Men who attempted weight loss were more likely than women to lose and maintain ?10 lb over 1 year (OR = 1.41; 95% CI = 1.20-1.65) and increase exercise and eat less fat as weight loss strategies; women were more likely to join weight loss programs, take prescription diet pills, and follow special diets. A need exists for male-specific interventions to improve overweight and obese men's likelihood for accurate weight perception, attempted weight loss, and ultimately, successful weight loss.

  • Trends in menopausal hormone therapy use of US office-based physicians, 2000-2009 MENOPAUSE-THE JOURNAL OF THE NORTH AMERICAN MENOPAUSE SOCIETY Tsai, S. A., Stefanick, M. L., Stafford, R. S. 2011; 18 (4): 385-392

    Abstract

    The aim of this study was to evaluate recent trends and the adoption of practice recommendations for menopausal hormone therapy (MHT) use from 2001 to 2009 by formulation, dose, woman's age, and characteristics of physicians reporting MHT visits.The IMS Health (Plymouth Meeting PA) National Disease and Therapeutic Index physician survey data from 2001 to 2009 were analyzed for visits in which MHT use was reported by US office-based physicians. Estimated national volume of visits for which MHT use was reported.MHT use declined each year since 2002. Systemic MHT use fell from 16.3 million (M) visits in 2001 to 6.1 M visits in 2009. Declines were greatest for women 60 years or older (64%) but were also substantial for women younger than 50 years (59%) and women 50 to 59 years old (60%). Women 60 years or older accounted for 37% of MHT use. Lower dose product use increased modestly, from 0.7 M (2001) to 1.3 M (2009), as did vaginal MHT use, from 1.8 M (2001) to 2.4 M (2009). Declines in continuing systemic MHT use (65%) were greater than for newly initiated MHT use (51%). Compared with other physicians, obstetrician/gynecologists changed their practices less, thereby increasing their overall share of total MHT visits from 72% (2001) to 82% (2009).Total MHT use has steadily declined. Increased use of lower dose and vaginal products reflects clinical recommendations. Uptake of these products, however, has been modest, and substantial use of MHT continues in older women.
