Temporal changes in trying to lose weight and recommended weight-loss strategies among overweight and obese Americans, 1996-2003.

OBJECTIVES: We examined whether the reported prevalence of trying to lose weight among overweight and obese individuals has changed over time, and whether those trying to lose weight report using recommended weight-loss strategies. METHODS: We used Behavioral Risk Factor Surveillance System data from 50 states and the District of Columbia during 1996, 1998, 2000, and 2003. The sample included participants with a self-reported Body Mass Index (BMI) of > or =25.0 kg/m(2) (N=333,378). The prevalence of trying to lose weight and eating fewer calories, using physical activity, or both, were examined for endpoint change and linear trends. RESULTS: Between 1996 and 2003, the prevalence of trying to lose weight among obese individuals increased significantly, while it remained stable among overweight individuals. The prevalence of eating fewer calories, using physical activity and using a combination of both increased significantly over time among the overweight and obese individuals trying to lose weight. CONCLUSION: Despite a rise in the number of overweight and obese people, there was little change among overweight adults in trying to lose weight over time, and a modest-but significant-change among obese adults in trying to lose weight over time. Among those who reported trying to lose weight, there were significant increases in their efforts to use recommended strategies.

A home-based nutrition and physical activity intervention for grandparents raising grandchildren: a pilot study.

Five African American grandparents raising their grandchildren participated in a home-based nutrition and physical activity intervention. The primary goals were to increase grandparents' knowledge and skills in selecting and preparing healthy foods and to increase the grandparents' and grandchildren's physical activity levels. Results revealed that grandparents' concerns regarding their chronic diseases and desire to prevent health problems in their grandchildren served as motivators. Following the intervention, grandparents scored higher on nutrition and physical activity knowledge and their self-efficacy improved, although most health status indicators remained unchanged. Self-reported changes included walking more, reading food labels, and switching to a healthier type of fat.

Grandparents raising grandchildren: a response to a nutrition and physical activity intervention.

This pilot study explored the impact of an educational program on nutrition and physical activity knowledge of urban African-American grandparents raising their grandchildren. The program was integrated into a community-based intervention, Project Healthy Grandparents, and was implemented during the first 15 minutes of 10 grandparent support groups and parenting classes. Subjects included 22 grandparents who attended at least six sessions and completed pre- and posttests of nutrition and physical activity knowledge. Participants' posttest scores were significantly higher than their pretest scores (P<0.05), indicating an increase in knowledge. Eighteen grandparents provided insights about diet and physical activity and barriers to lifestyle changes during an audiotaped focus group. Based on analysis of the focus group's discussion, three major influences on healthful eating and physical activity emerged, including financial considerations, presence of grandchildren in the home, and preference for traditional cultural foods. Themes from the focus group were consistent with responses on the nutrition and physical activity knowledge test. Satisfaction with the program was very high and no specific recommendations for improvements were made. Results can guide future nutrition interventions for this target group and potentially contribute to grandparents' improved health and ability to care for their grandchildren.

Quality of life and diabetes knowledge of young persons with type 1 diabetes: Influence of treatment modalities and demographics.

OBJECTIVE: The primary objective of this descriptive study was to assess the perception of quality of life and diabetes knowledge among young persons with type 1 diabetes. The secondary objectives were to examine the influence of treatment modality (continuous subcutaneous insulin infusion vs multiple daily injections) and demographics on quality of life and diabetes knowledge of these young persons and to determine the associations between the study variables. RESEARCH DESIGN AND METHODS: Participants aged 9 to 17 years (n=103) completed the diabetes-specific measure of quality of life and a diabetes knowledge test. Parents of these young persons completed a history questionnaire. Descriptive statistics, independent t tests, and Pearson's correlations were used to analyze the data. RESULTS: Overall, diabetes-specific measure of quality-of-life scores indicated good quality of life among the study population. Mean scores on the impact, worry, and satisfaction subscales did not indicate negative perceptions of the disease. Body mass index was significantly inversely correlated with the satisfaction scale ( r =-0.247, P =.023). Self-rated health was negatively correlated with the impact ( r =-0.221, P =.038) and worry scale ( r =-0.294, P =.004) and positively correlated with the satisfaction scale ( r =0.291, P =.004). Seventy-two percent correct responses were given on the diabetes knowledge test. Knowledge was significantly correlated to diabetes diagnosis age ( r =0.276, P =.009) and current age ( r =0.453, P =.0005). No significant differences were observed between participants using continuous subcutaneous insulin infusion vs multiple daily injections in regard to diabetes-specific measure of quality of life and diabetes knowledge test. CONCLUSIONS: In our study, young persons with type 1 diabetes had a positive perception of their quality of life and above-average diabetes knowledge, which were influenced by several factors, such as self-rated health, body mass index, and age at diagnosis. Dietetics professionals should assess perceived quality of life and knowledge among young persons with type 1 diabetes because these factors can potentially influence disease management and treatment compliance.

Recommendations for nutrition interventions with overweight African-American adolescents and young adults at the Atlanta Job Corps Center.

Focus groups were used to gain insight into the nutrition-related attitudes and motivations of overweight African-American adolescents and young adults enrolled in the Atlanta Job Corps Center in preparation for designing an effective and culturally appropriate nutrition intervention for this population. Eighteen students and 18 staff members participated in six different focus groups. Focus group themes suggest that an intervention with this target group should address overeating, proper diet composition, emotional eating, long-term consequences of a poor diet, group work, and incentives. Limiting food portions, offering healthy, appealing food choices, and displaying nutritional content of foods in the cafeteria were also suggested. It was also suggested that the intervention should be ongoing and led by someone who is patient, supportive, and has overcome an overweight problem. An intervention based on these recommendations can be specifically tailored to this target group and, potentially, be effective in changing dietary behaviors and lifestyle.

Effect of a nutrition education program on nutrition-related knowledge of English-as-second-language elementary school students: a pilot study.

Nutrition programs that target English-as-Second-Language (ESL) students can potentially improve their nutrition knowledge. This pilot study evaluated the effect of a Food Guide Pyramid (FGP) lesson on nutrition knowledge of ESL students (ages 9-12 years) in a refugee after-school program. A pre- and post-FGP lesson one group design was used. A 12-item knowledge questionnaire was administered to students (N = 15) and their opinions about the lesson were obtained. Overall FGP lesson mean knowledge scores did not increase significantly from pretest to posttest; however, scores that measured specific objectives on the ability to identify food groups and the number of servings for food groups increased, while scores on the ability to identify the importance of each food group for health decreased. Overall, students liked the nutrition lesson, described learning mainly about the FGP, and reported no confusing aspects. Findings suggest that nutrition education targeted to ESL students should emphasize foods versus nutrients and promote active learner involvement.

Prevalence of metabolic syndrome risk factors among young adult Asian Indians.

Metabolic syndrome has a high prevalence within the U.S population. Asian Indians have a greater prevalence of the chronic diseases associated with this syndrome compared to Caucasians. This study aimed to determine the prevalence of risk factors of metabolic syndrome in young adult Asian Indians. Behavioral risk factors, dietary intake, and anthropometric measurements were assessed on all study participants (n=50). The mean BMI was 23.2 and 20.4, waist circumference was 87 and 79 cm, and percent body fat was 16 and 26% for males and females, respectively. Macronutrient contributions to the total energy intake were: carbohydrate 55% for males and females, protein 14 and 12% for males and females respectively, and total fat 31 and 33% for males and females, respectively. Using the definition of the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (Adult Treatment Panel III, ATP III), these Asian Indians did not appear to be at high risk for developing metabolic syndrome. However, using the newly proposed recommendations for Asian Indians, the results suggest that this group may be at risk for developing metabolic syndrome.
