How prescriptive support affects weight loss in weight-loss intervention participants and their untreated spouses.

Objective: Controlling or prescriptive support styles (e.g., pressure) often hinder weight loss, but can sometimes be beneficial.

Randomized Controlled Trial Examining the Ripple Effect of a Nationally Available Weight Management Program on Untreated Spouses.

Objective: For married couples, when one spouse participates in weight loss treatment, the untreated spouse can also experience weight loss. This study examined this ripple effect in a nationally available weight management program.

Methods: One hundred thirty dyads were randomized to Weight Watchers (WW; n = 65) or to a self-guided control group (SG; n = 65) and assessed at 0, 3, and 6 months.

Occupation Is Related to Weight and Lifestyle Factors Among Employees at Worksites Involved in a Weight Gain Prevention Study.

Objective: To examine the relationship between job type, weight status, and lifestyle factors that are potential contributors to obesity including, diet, physical activity (PA), and perceived stress among employees enrolled in the Working on Wellness project.

Methods: Randomly selected employees at 24 worksites completed a baseline survey (n = 1700); some also an in-person survey and anthropometric measures (n = 1568). Employees were classified by US labor standards as white collar (n = 1297), blue collar (n = 303), or service worker (n = 92), and 8 unknown.

Secondary prevention of HIV in the United States: past, current, and future perspectives.

To provide a synopsis of past, current, and potential next-generation approaches to prevention for positives (PfP) interventions in the United States. For a variety of reasons, PfP interventions, with the goals of limiting HIV transmission from people living with HIV/AIDS (PLWHA) to others and protecting the health of PLWHA, did not appear with any frequency in the United States until about 2000. Even today, the number and breadth of evidence-based PfP interventions is very limited.

Bacterial profiling of soil using genus-specific markers and multidimensional scaling.

Forensic identification of soil based on microbial DNA fingerprinting has met with mixed success, with research efforts rarely considering temporal variability or local heterogeneity in soil's microbial makeup. In the research presented, the nitrogen fixing bacteria rhizobia were specifically examined. Soils were collected monthly from five habitats for 1 year, and quarterly in each cardinal direction from the main collection site.
