Body size perception and ideal body size in overweight and obese young adult women.

PURPOSE: The purpose of this study was to examine the differences among actual body size, perceived body size, and ideal body size in overweight and obese young adult women. METHODS: Actual body size was assessed by body mass index (BMI), while self-perceived and ideal body sizes were assessed by the Body image assessment tool-body dimension. Descriptive statistics were calculated and analysis of variance (ANOVA) was performed on actual BMI as a function of perceived BMI. RESULTS: Of the 42 participants included in the study, 12 were overweight (25 ≤ BMI < 30), 18 were obese 1 (30 ≤ BMI < 35), and 12 were obese 2 (35 ≤ BMI ≤ 39.48). The mean ideal body size of participants was 25.34 ± 1.33. Participants in general perceived their body size (BMI: 35.82 ± 1.06) to be higher than their actual body size (32.84 ± 0.95). Overweight participants had a significantly higher mean body size misperception than obese 2 individuals (µ dif = -6.68, p < .001). CONCLUSION: Perception accuracy of body size differs in women by BMI. Weight loss programs need to be tailored to consider body size misperception in order to improve treatment outcomes for overweight and obese young women.

Lifestyle habits and obesity progression in overweight and obese American young adults: Lessons for promoting cardiometabolic health.

Obesity among young adults is a growing problem in the United States and is related to unhealthy lifestyle habits, such as high caloric intake and inadequate exercise. Accurate assessment of lifestyle habits across obesity stages is important for informing age-specific intervention strategies to prevent and reduce obesity progression. Using a modified version of the Edmonton Obesity Staging System (mEOSS), a new scale for defining obesity risk and predicting obesity morbidity and mortality, this cross-sectional study assessed the prevalence of overweight/obese conditions in 105 young adults and compared their lifestyle habits across the mEOSS stages. Descriptive statistics, chi-square tests, and one-way analyses of variance were performed. Eighty percent of participants (n = 83) fell into the mEOSS-2 group and had obesity-related chronic disorders, such as diabetes, hypertension, and/or dyslipidemia. There were significant differences in dietary quality and patterns across the mEOSS stages. Findings highlighted the significance of prevention and early treatment for overweight and obese young adults to prevent and cease obesity progression.

A feasibility study to develop a diabetes prevention program for young adults with prediabetes by using digital platforms and a handheld device.

PURPOSE: The purpose of this pilot study was to examine the feasibility and preliminary efficacy of an age-specific diabetes prevention program in young adults with prediabetes. METHODS: A one-group pretest-posttest design was used. The inclusion criteria were age 18 to 29 years and the presence of prediabetes (either impaired fasting glucose of 100-125 mg/dL [5.55-6.94 mmol/L] or A1C of 5.7%-6.4%). Fifteen participants were enrolled in the study. A technology-based lifestyle coaching program focused on diet and physical activity and incorporating a handheld device and digital platforms was developed and tested. Psychosocial factors (health literacy, illness perception, self-efficacy, therapeutic efficacy) based on social cognitive theory, changes in diet and physical activity, and cardiometabolic risk factors were assessed at baseline and week 12 after the intervention. A paired-samples t test was performed to examine changes between baseline and postintervention on each psychosocial and physical variable. RESULTS: Participants' (n = 13 completers) mean age was 24.4 ± 2.2 years, 23.1% were male, and 53.8% were African American. Overall, the participants were satisfied with the intervention (mean score, 4.15 on a 5-point, Likert-type scale). Between pre- and posttesting, mean body mass index and mean A1C decreased from 41.0 ± 7.3 kg/m(2) and 6.0 ± 0.5% to 40.1 ± 7.0 kg/m(2) and 5.6 ± 0.5%, respectively, whereas mean fasting glucose did not significantly change (from 92.6 ± 11 to 97.6 ± 14.3 mg/dL [5.14 ± 0.61 to 5.42 ± 0.79 mmol/L]). CONCLUSIONS: The intervention resulted in reduced A1C and a trend toward decreased body mass index in obese sedentary young adults with prediabetes after 12 weeks. Further study through a randomized clinical trial with a longer intervention period is warranted.

Health literacy, self-efficacy, food label use, and diet in young adults.

OBJECTIVES: To examine relationships among health literacy, self-efficacy, food label use, and dietary quality in young adults aged 18-29. METHODS: Health literacy, self-efficacy, food label use, and dietary quality were assessed. Participants were categorized into low, medium and high health literacy groups based on Newest Vital Sign score. RESULTS: Self-efficacy and health literacy were predictors of food label use, which positively predicted dietary quality. The low health literacy group had significantly lower use of food labels than the high health literacy group. However, there was no significant difference between medium and high health literacy groups. CONCLUSION: Strategies to enhance health literacy, self-efficacy and food label use should be developed to improve dietary quality and health outcomes.
