Preventing weight gain rather than treating recognized obesity is an important economic and public health response to the growing levels of obesity nationwide. Community centers offer potential sites for community health promotion programs targeting African Americans. In this article, results from a pilot health promotion program at a community center are reported.

People United to Sustain Health (PUSH) was designed to increase fruit and vegetable consumption, physical activity, and food security to prevent weight gain in rural adults. Forty-nine participants were randomized into a treatment group which received access to a "Rolling Store," nutrition education and physical activity, and a control group which received family coping classes.

The Louisiana (LA) Health study utilized a longitudinal, cluster randomized three-arm controlled design, with 28 months of follow-up. Children (N = 2,060; mean age = 10.

Methods: A sample of 43 overweight adults 35 to 64 years of age participated in a one week pedometer-based feasibility trial monitored by accelerometry. Participants were randomized into a one-week education-only group or a group that also wore a pedometer.
In this paper, challenges to recruiting African Americans specifically for a dietary feeding trial are examined, learning experiences gained and suggestions to overcome these challenges in future trials are discussed. A total of 333 individuals were randomized in the trial and 234 (167 sibling pairs and 67 parents/siblings) completed the dietary intervention and required DNA blood sampling for genetic analysis. The trial used multiple strategies for recruitment.

Min·day(-1) in MVPA was a good predictor of steps·day(-1) (r(2) = 0.62; p < 0.

We wanted to determine how short-term and long-term weight loss and patterns of weight change were associated with intervention behavioral targets. This analysis includes overweight/obese participants in active treatment (n = 507) from the previously published PREMIER trial, an 18-month, multicomponent lifestyle intervention for blood pressure reduction, including 33 intervention sessions and recommendations to self-monitor food intake and physical activity daily.

Childhood obesity prevention trials suggest that, on average, overweight/obese children lose body weight and nonoverweight children gain weight. This investigation tested the hypothesis that overweight children lose body weight/fat and nonoverweight children gain body weight/fat using a longitudinal research design that did not include an obesity prevention program.
View Article and Find Full Text PDFRecruitment strategies employed by four clinical centers across the US and a coordinating center were examined to identify successful overall and minority-focused recruitment strategies for the PREMIER multicenter trial of lifestyle changes for blood pressure control. The goal was to recruit 800 adults (40% African Americans) with systolic blood pressure of 120-159 mm Hg and diastolic of 80-95 mm Hg, not taking antihypertensive medication. Clinical centers used combinations of mass distribution of brochures, mass media, email distribution lists, screening events, and a national website.

Methods: Forty eligible African American women were enrolled in the study and randomized to intervention or control groups. A trained peer educator and a Rolling Store operator implemented the study protocol at a local community center.
Objective: Rates of obesity among children have been rising in recent years. Information on the prevalence of obesity in children living in rural communities is needed. We report the prevalence of overweight and obesity in children enrolled in grades 4 to 6 who live in rural areas of Louisiana, USA.
View Article and Find Full Text PDFObjectives: To examine whether participants with the most behavioral goals to achieve were more likely to meet more goals than those given fewer goals.
Methods: Eight hundred ten participants were randomly assigned to advice-only, established guidelines for blood pressure control (reduced sodium, increased physical activity), or established guidelines plus the DASH diet (increased fruits, vegetables, low-fat dairy, reduced fat).
Results: At 6 months, 11.
Background: The Weight Loss Maintenance Trial (WLM) is a multi-center, randomized, controlled trial that compares the effects of two 30-month maintenance interventions, i.e., Personal Contact (PC) and Interactive Technology (IT) to a self-directed usual care control group (SD), in overweight or obese individuals who are at high risk for cardiovascular disease.

Prevention of obesity, especially in children, has been deemed by public health policy makers to be one of the most important objectives for our country. This prevention project, called Louisiana (LA) Health, will test whether modification of environmental and behavioral factors can prevent inappropriate weight gain in children from rural parishes of Louisiana who are enrolled in the fourth to sixth grades during Year 1.

Objective: To compare 2 weight loss maintenance interventions with a self-directed control group.
Design, Setting, And Participants: Two-phase trial in which 1032 overweight or obese adults (38% African American, 63% women) with hypertension, dyslipidemia, or both who had lost at least 4 kg during a 6-month weight loss program (phase 1) were randomized to a weight-loss maintenance intervention (phase 2).
Objective: To determine if measures of diet quality differ between food insecure and food secure adults in a rural high-risk population.
Design: Random digit dialing telephone survey of a cross-section of the population designed to collect data on food intake, household demographics, and food security status.
Setting: A representative sample of adults who live in 36 counties in the Lower Mississippi Delta region of Arkansas, Louisiana, and Mississippi.
Lifestyle modification can reduce blood pressure and lower cardiovascular risk. Established recommendations include weight loss, sodium reduction, and increased physical activity. PREMIER studied the effects of lifestyle interventions based on established recommendations alone and with the addition of the Dietary Approaches to Stop Hypertension (DASH) dietary pattern.
View Article and Find Full Text PDFObjectives: To assess contributions of individual lifestyle changes on systolic blood pressure (SBP) changes.
Methods: We examined associations between lifestyle behavior changes and SBP after 6 and 18 months in 782 PREMIER trial participants.
Results: In multivariate models omitting weight, predicted SBP reductions ranged from (1)/2 to 1(1)/2 mm Hg for reduced urinary sodium, improved fitness, and adherence to the DASH diet (except sodium at 18 months).
Context: The prevalence of childhood overweight status is increasing. Some have suggested that childhood overweight is associated with food insecurity, defined as limited or uncertain access to enough nutritious food.
Objectives: The purpose of this work was to assess the association of household and child food insecurity with childhood overweight status.
Background: The hypothesis that alterations in energy metabolism predict body fat gain is controversial.
Objective: The aim of this study was to determine which components of energy metabolism were most important in predicting fat gain in children aged 10.8 +/- 0.
Interventions encouraging adoption of healthy diets and increased physical activity are needed to achieve national goals for preventing and treating hypertension, cardiovascular disease, diabetes, and other chronic diseases. PREMIER was a multicenter clinical trial testing the effects of two lifestyle interventions on blood pressure control, compared with advice only. Both interventions implemented established national guidelines for blood pressure control (weight loss, reduced sodium and alcohol intake, and increased physical activity), and one intervention also included the Dietary Approaches to Stop Hypertension (DASH) diet.
View Article and Find Full Text PDFBackground: The main 6-month results from the PREMIER trial showed that comprehensive behavioral intervention programs improve lifestyle behaviors and lower blood pressure.
Objective: To compare the 18-month effects of 2 multicomponent behavioral interventions versus advice only on hypertension status, lifestyle changes, and blood pressure.
Design: Multicenter, 3-arm, randomized trial conducted from January 2000 through November 2002.
