Effects of energy-content labels and motivational posters on sales of sugar-sweetened beverages: stimulating sales of diet drinks among adults study.

This study examined the effects of an environmental intervention promoting more non-energy-containing beverage consumption compared to sugar-sweetened soft drink consumption through vending machines in an urban college setting. Eight soft drink vending machines were randomly selected and assigned to one of three conditions over a 9-week period: energy-content labels on non-energy-containing beverage selection panels (intervention I), labels plus motivational posters (intervention II), or control. The totals of all beverages sold and machine revenue were recorded at baseline (2 weeks), intervention (5 weeks), and postintervention (2 weeks) periods. Use of energy-content labels and motivational posters, compared with control group, resulted in a significantly lower growth rate of sugar-sweetened beverage sales (P<0.05). Total revenue for all beverages increased during the intervention period. It is estimated that the non-energy-containing beverages combined accounted for 70.52% of the increased revenue. Results of this study suggest that energy-content labels and motivational posters on beverage vending machines may be an effective way to influence beverage sales.

Public health strategies for preventing and controlling overweight and obesity in school and worksite settings: a report on recommendations of the Task Force on Community Preventive Services.

Reducing morbidity and mortality related to overweight and obesity is a public health priority. Various interventions in school and worksite settings aim to maintain or achieve healthy weight. To identify effective strategies for weight control that can be implemented in these settings, the Task Force on Community Preventive Services (Task Force) has conducted systematic reviews of the evidence on nutrition, physical activity, combinations of these interventions, and other behavioral interventions (e.g., cognitive techniques such as self-awareness and cue recognition). Task Force recommendations are based on evidence of effectiveness, which is defined in this report as achieving a mean weight loss of > or =4 pounds, measured > or =6 months after initiation of the intervention program. The Task Force recommends multicomponent interventions that include nutrition and physical activity (including strategies such as providing nutrition education or dietary prescription, physical activity prescription or group activity, and behavioral skills development and training) to control overweight and obesity among adults in worksite settings. The Task Force determined that insufficient evidence existed to determine the effectiveness of combination nutrition and physical activity interventions to prevent or reduce overweight and obesity in school settings because of the limited number of qualifying studies reporting noncomparable outcomes. This report describes the methods used in these systematic reviews; provides additional information regarding these recommendations; and cites sources for full reviews containing details regarding applicability, other benefits and harms, barriers to implementation, research gaps, and economic data (when available) regarding interventions.

Impediment profiling for smoking cessation. Preliminary experience.

INTRODUCTION: Cigarette smoking is a leading cause of preventable death. METHODS: Long and short "impediment profilers" (LIPs and SIPs, respectively) addressing nicotine addiction, depression, anxiety, stress, chemical dependency, weight control, and household smoking were developed and applied in a pilot smoking cessation study to tailor treatment. RESULTS: Quit rate 72 hours after the target quit date was 50%; at 8 and 12 weeks it was 61% and 39%, respectively. The LIP identified fewer impediments than the SIP. CONCLUSIONS: Impediment profiling for tailored smoking cessation intervention is associated with high initial quit rates and warrants further study.

Technical skills for weight loss: preliminary data from a randomized trial.

BACKGROUND: Optimal behavioral interventions for sustainable weight loss are uncertain. We therefore conducted a study among overweight/obese women comparing conventional dietary counseling of individuals (counseling-based intervention) to a novel, group-based skill-building intervention. METHODS: Eighty subjects were randomly assigned to either the counseling-based or to the skill-building intervention. Outcomes included weight loss, dietitian hours per group and per unit weight loss, and dollars spent per group and per unit weight lost. RESULTS: Weight loss at 6 months (follow-up rate 61.3%) in the counseling-based group was 8.8 lb (P = 0.0001), and in the skill-building group was 3.8 lb (P = 0.01). A total of 160 dietitian hours were required for the counseling-based group, and 131 for the skilled-building group. The counseling-based group cost an average of $21 per pound lost, while the skill-building cost an average of $48 per pound lost (P = 0.16). CONCLUSIONS: At 6 months, individualized office-based counseling produced more weight loss than a skill-building approach and cost less than half as much per pound of weight loss. Longer-term follow-up is required to determine if, as hypothesized, the skill-building intervention produces more sustainable weight loss.

Impediment profiling for smoking cessation: results of a pilot study.

OBJECTIVE: To test the effectiveness of a smoking cessation program based on "impediment profiling," the elucidation of an individual participant's personal barriers, with provision of tailored interventions accordingly. METHODS: A literature search was conducted to identify established impediments to smoking cessation. A long impediment profiler (LIP) was developed from validated survey instruments and used as a screening tool to identify individuals' barriers to quitting. Once barriers were identified, participants were assigned to up to seven interventions. Self-reported smoking cessation was confirmed with measurements of carbon monoxide concentrations in expired air of < or = 10 ppm. RESULTS: Nineteen adults participated in the pilot program. At the year 1 mark, 63.2% of the study population was smoke-free. The mean number of impediments of the study population was 3.5 +/- 1.5. There was a negative association between subjects' quit status and the following impediments: stress (p = .0061), anxiety (p = .0445), and depression (p < .001). No single impediment was predictive of quit status. CONCLUSIONS: Impediment profiling as a basis for tailored smoking cessation intervention is associated with a high quit rate in this initial study, and it appears promising. Long-term follow-up is warranted, as is replication in a larger cohort with a concurrent control group.
