Corrigendum to “Validation of the Yale Food Addiction Scale among a weight-loss surgery population” [Eating Behaviors 14(2013) 216–219]

The Yale Food Addiction Scale (YFAS), recently validated in college students and binge eaters, is a means to assess “food addiction” in accordance with DSM-IV criteria for substance dependence. Using online survey methodology, we aimed to validate the use of the YFAS among weight loss surgery (WLS) patients. Participants completed measures about pre-WLS food addiction (YFAS), emotional and binge eating, behavioral avoidance and inhibition, and pre- and post-WLS substance use. A sample of 67 WLS patients (59.7% Roux-en-Y) was recruited; participants were 62.7% female, 86.6% Caucasian, had a mean age of 42.7; and 53.7% met criteria for pre-WLS food addiction. Convergent validity was found between the YFAS and measures of emotional eating (r = .368, p < .05) and binge eating (r = .469, p < .05). Discriminant validity was supported in that problematic substance use, behavioral avoidance, and behavioral inhibition were not associated with YFAS scores. Incremental validity was supported in that the YFAS explained a significant proportion of additional variance in binge eating scores, beyond that predicted by emotional eating (EES) and disordered eating behavior (EAT-26). There was a nonsignificant trend towards those with higher food addiction being more likely to admit to post-WLS problematic substance use (i.e., potential “addiction transfer”; 53% vs. 39%). Results support the use of the YFAS as a valid measure of food addiction among WLS patients. Future research with a larger sample may shed light on potentially important relationships between pre-surgical food addiction and both weight and substance use outcomes.

Results

There was a significant relationship between the YFAS symptom count and emotional eating (EES), r = .368, p < .05, and between the YFAS symptom count and binge eating (BES), r = .469, p < .05. The relationship between the YFAS symptom count and behavioral inhibition (BIS) trended towards significance, r = − .262, p = .051. There was no significant relationship between the YFAS symptom count and behavioral avoidance (BAS), r = .098, p = .471, or between the YFAS symptom count and eating disorder severity (EAT-26, r = .148, p = .253. No association was observed between food addiction and problematic substance use.With respect to meeting diagnostic criteria for food addiction (yes/no), there was a significant relationship between food addiction and emotional eating, r = .468, p < .05, binge eating r = .254, p < .05, and symptoms of eating disorders, r = .327, p < .05. There was no significant relationship between food addiction classification and behavioral inhibition or behavioral avoidance. Table 1 displays the correlations between the YFAS and measures of both eating behaviors and substance use.Eating pathology; including symptoms of eating disorders and emotional eating, were significant predictors of binge eating, accounting for 42% of the variance. After controlling for eating pathology in step one, the YFAS explained a significant proportion of additional variance in binge eating scores, R² = .421 for Step 1, ∆R² = .060 for Step 2, F(2,1) = 17.018, p = < .001. Table 2 reports the outcomes of the linear regression conducted to confirm incremental validity of the YFAS over other measure known to predict problematic eating behaviors.Additionally, those meeting criteria for food addiction had poorer total percent weight loss outcomes (32% vs. 27%; p = .220) and were more likely to admit to post-WLS problematic substance use (i.e., potential “addiction transfer”; 53% vs. 39%; p = .126), but neither of these comparisons attained statistical significance.The authors would like to apologize for any inconvenience caused.     

Validation of the Yale Food Addiction Scale among a weight-loss surgery population

The Yale Food Addiction Scale (YFAS), recently validated in college students and binge eaters, is a means to assess “food addiction” in accordance with DSM-IV criteria for substance dependence. Using online survey methodology, we aimed to validate the use of the YFAS among weight loss surgery (WLS) patients. Participants completed measures about pre-WLS food addiction (YFAS), emotional and binge eating, behavioral activation and inhibition, and pre- and post-WLS substance use. A sample of 67 WLS patients (59.7% Roux-en-Y) was recruited; participants were 62.7% female, 86.6% Caucasian, had a mean age of 42.7; and 53.7% met the criteria for pre-WLS food addiction. Convergent validity was found between the YFAS and measures of emotional eating (r = .368, p < .05) and binge eating (r = .469, p < .05). Discriminant validity was supported in that problematic substance use, behavioral activation, and behavioral inhibition were not associated with YFAS scores. Incremental validity was supported in that the YFAS explained a significant proportion of additional variance in binge eating scores, beyond that predicted by emotional eating (EES) and disordered eating behavior (EAT-26). Those meeting the food addiction criteria had poorer percent total weight loss outcomes (32% vs. 27%). There was a nonsignificant trend towards those with higher food addiction being more likely to admit to post-WLS problematic substance use (i.e., potential “addiction transfer”; 53% vs. 39%). Results support the use of the YFAS as a valid measure of food addiction among WLS patients. Future research with a larger sample may shed light on potentially important relationships between pre-surgical food addiction and both weight and substance use outcomes.     

Beyond alcohol and drug addiction. Does the negative trait of low distress tolerance have an association with overeating?

Low distress tolerance is an inability to withstand negative emotions. The connection between low distress tolerance and addiction to cigarettes, alcohol, and illegal drugs has been established. The purpose of the current study was to extend this work to overeating, which is an important symptom of food addiction. We investigated whether low distress tolerance was related to overeating as measured by the emotional and external eating scales of the Dutch Eating Behavior Questionnaire and the disinhibition scale of the Three-Factor Eating Questionnaire. Participants were 225 college students with a median age of 19; 32% were overweight or obese. Linear regression models adjusting for sex and BMI demonstrated significant inverse associations among distress tolerance and emotional eating (P = 0.001), external eating (P = 0.002), and disinhibition (P < 0.001). These initial results suggest the importance of additional research in the area of low distress tolerance, overeating, and food addiction.     

Sexual Knowledge,Sexual Attitude,and Life Satisfaction Among Korean Older Adults: Implications for Educational Programs

The aim of this study was to: identify the sexual knowledge, sexual attitude, and life satisfaction in Korean older adults; and explore significant factors among demographic characteristics, sexual activity, sexual knowledge, and sexual attitude, that influence life satisfaction among Korean older adults. Participants were recruited in community centers and public parks (N = 571). Data were collected on sexual knowledge, sexual attitudes, and life satisfaction using three valid and reliable instruments. Data were analyzed using t test, ANOVA, Pearson’s correlation, and hierarchical multiple regression. Educational level, gender, and living arrangement significantly affected sexual knowledge and attitudes (p < .001) among older adults. There was a positive relationship between sexual knowledge and attitudes (r = .490, p < .001), life satisfaction and sexual knowledge (r = .144, p = .001), and life satisfaction and sexual attitudes (r = .121, p = .004). Age (β = .16, t = 3.45, p < .01), gender (β = .52, t = 2.07, p < .05), presence of spouse (β = ?.12, t = ?2.42, p < .05), and sexual knowledge (β = .10, t = 2.17, p < .05) were factors with a significant influence on life satisfaction for older adults. When designing and implementing sexual counseling and education programs for older adults, individual background, sexual knowledge, and sexual attitudes must be assessed and considered. Also, those without spouses who live alone may need more attention because they tend to have low knowledge levels and negative attitudes toward sexual activity.     

Relationship of Diet-Health Attitudes and Nutrition Knowledge of Household Meal Planners to the Fat and Fiber Intakes of Meal Planners and Preschoolers

The relationship of household meal planners’ diet-health attitudes and nutrition knowledge to their fat and fiber intakes and to the intakes of 2- to 5-year-old children in the households was examined using data from the 1989–91 Continuing Survey of Food Intake by Individuals and Diet Health Knowledge Survey (CSFII/DHKS). Selected households (n = 478) provided 24-hour diet recalls and the households’ main meal planners responded to the DHKS. Meal planner attitude variables were defined according to the Health Belief Model and selected CSFII/DHKS questions served as proxy measures. The relationship of meal planners’ attitudes and knowledge to meal planners’ and children's fat and fiber consumption at home and in the total diet was analyzed using multiple regression. Several diet-health attitude variables were significantly related to meal planners’ fat and fiber intakes and relationships were similar for foods eaten at home and for foods eaten in the total diet. Knowledge was significantly related to meal planners’ and children's home fat intake (p < .05) but the relationships failed to reach statistical significance for the total diets. Meal planners’ taste concerns differed significantly in their relationship to meal planners’ and children's fiber consumption (p < .05). Results indicate that parents’ diet-health attitudes are more influential in their diets than in the diets of preschoolers. Findings also suggest that taste and practical food concerns are significant barriers to healthy eating among younger adults and that general nutrition knowledge may not be as helpful in making healthy food choices outside the home as it may be in the home setting.     

Eating Behavior,Physical Activity and Exercise Training: A Randomized Controlled Trial in Young Healthy Adults

Regular physical activity (PA) is an important part of the treatment of several medical conditions, including overweight and obesity, in which there may be a weakened appetite control. Eating behaviour traits influence weight control and may be different in active and sedentary subjects. This paper reports the relationships between the time spent in sedentary behaviour and physical activity (PA) of different intensity, and eating behaviour traits in young, healthy adults. Additionally, it reports the results of a six-month-long, randomized, controlled trial to examine the effect of an exercise intervention on eating behaviour traits. A total of 139 young (22.06 ± 2.26 years) healthy adults (68.35% women) with a Body Mass Index (BMI) of 24.95 ± 4.57 kg/m² were enrolled. Baseline assessments of habitual PA were made using wrist-worn triaxial accelerometers; eating behaviour traits were examined via the self-reported questionnaires: Binge Eating, Three-Factor Eating Questionnaire-R18 and Control of Eating Questionnaire. The subjects were then randomly assigned to one of three groups: control (usual lifestyle), moderate-intensity exercise (aerobic and resistance training 3¨C4 days/week at a heart rate equivalent to 60% of the heart rate reserve (HRres) for the aerobic component, and at 50% of the 1 repetition maximum (RM) for the resistance component), or vigorous-intensity exercise (the same training but at 80% HRres for half of the aerobic training, and 70% RM for the resistance training). At baseline, sedentary behaviour was inversely associated with binge eating (r = −0.181, p < 0.05) and with uncontrolled eating (r = −0.286, p = 0.001). Moderate PA (MPA) was inversely associated with craving control (r = −0.188, p < 0.05). Moderate-to-vigorous PA (MVPA) was directly associated with binge eating (r = 0.302, p < 0.001) and uncontrolled eating (r = 0.346, p < 0.001), and inversely associated with craving control (r = −0.170, p < 0.015). Overall, PA was directly associated with binge eating (r = 0.275, p = 0.001), uncontrolled eating (r = 0.321, p < 0.001) and emotional eating (r = 0.204, p < 0.05). Additionally, only emotional eating was modified by the intervention, increasing in the vigorous-intensity exercise group (p < 0.05). In summary, we observed that time spent in sedentary behaviour/PA of different intensity is associated with eating behaviour traits, especially binge eating in young adults. In contrast, the six-month exercise intervention did not lead to appreciable changes in eating behaviour traits.     

Subjective Social Status Is Associated with Dysregulated Eating Behaviors and Greater Body Mass Index in an Urban Predominantly Black and Low-Income Sample

Background: Higher subjective social status (SSS) or a person’s perception of their social standing is related to better health outcomes, but few studies examined SSS in relation to obesity. Emotional eating and food addiction have been linked to obesity. Some studies indicated that manipulating SSS may lead to altered food intake, but the relationship between SSS and dysregulated eating, such as emotional eating and food addiction (FA), has not been examined. The goal of this study was to examine the associations between SSS in the community and the larger society, dysregulated eating (emotional eating and FA), and body mass index (BMI) in a majority racial minority sample. Methods: The participants (N = 89; 93% Black, 86% women, and 56% with obesity; 72% income lower than USD 2000), recruited from a publicly funded hospital in Atlanta, GA, completed the MacArthur Scale, Dutch Eating Behaviors Questionnaire, Yale Food Addiction Scale, Beck Depression Inventory, PTSD Symptom Checklist, and demographics questionnaire. Results: Twenty-two percent of the sample met the criteria for FA; those with FA had significantly higher BMI than those without (p = 0.018). In the hierarchical linear regression, the SSS community (but not in society) predicted higher severity of emotional eating (β = 0.26, p = 0.029) and FA (β = 0.30, p = 0.029), and higher BMI (β = 0.28, p = 0.046), independent from depression and PTSD symptoms. Conclusions: The findings indicate that, among Black individuals with predominantly low income in the U.S., perceived role in their community is associated with eating patterns and body mass. Given the small sample size, the results should be interpreted with caution.     

The Influence of Worries on Emotional Eating,Weight Concerns,and Body Mass Index in Latina Female Youth

PurposeTo investigate the effect of worries on weight concerns, emotional eating, and body mass index (BMI) percentile in an ethnically diverse sample of female youth.MethodsThis study used baseline and follow-up data from a brief school-based physical activity intervention trial involving minority female youth. Partial correlations adjusted for intervention status, age, and ethnicity were used to assess the relationships between emotional eating, weight concerns, and BMI percentile at follow-up. Multilevel modeling was used to analyze the relationships between baseline worries and follow-up emotional eating, weight concerns, and BMI percentile. Additional analysis assessed whether emotional eating mediated and/or moderated the relationship between baseline worries and follow-up BMI. Data were analyzed using SAS version 9.1.ResultsThe sample consisted of 404 minority females (67.1% Latina; mean age = 12.5 ± .6; 60.6% were of normal weight). Weight concerns were positively correlated with emotional eating and BMI percentile (p < .001 for both). At follow-up, baseline worries significantly predicted emotional eating (p = .027) and weight concerns (p < .001) but not BMI percentile (p = .183). Emotional eating did not mediate the relationship between baseline worries and follow-up BMI percentile; however, it did moderate the relationship between baseline worries and follow-up BMI percentile (p = .003).ConclusionsIn this sample, worries were associated with psychosocial variables but not with BMI percentile. Reducing worries in those with high emotional eating scores may influence future weight gain among Latina females.     

Emotional Intelligence and Emotional Eating Patterns: A New Insight into the Antecedents of Eating Disorders?

ObjectiveTo examine the association between emotional intelligence (EI) and emotional eating. The authors hypothesized that EI will negatively associate with emotional eating.MethodsA correlational study, conducted in a convenience sample. The researchers personally approached working adults in their workplaces. Ninety Israelis, selected to approximate the general working population, filled out EI and emotional eating standard measures, the Wong and Law Emotional Intelligence Scale and the Praeger questionnaire. Also gathered were data regarding sex, age, and education. Pearson correlations followed by hierarchical regressions were used to examine the associations between the core measures, controlling for background factors.ResultsFindings supported the hypothesis (r = .72; P < .001). Controlling for background factors, the partial correlation was r = .66 (P < .001). Higher scores in the Praeger measure reflect less emotional eating.Conclusions and implicationsThe authors propose that the present findings may serve future research as well as practitioners interested in identification of at-risk populations or seeking screening measures for the above issue.     

Orthorexia Nervosa and Disordered Eating Attitudes,Self-Esteem and Physical Activity among Young Adults

A relation between Orthorexia Nervosa (ON) and increased frequency of physical activity has been put in evidence by recent studies. It is well known that intense physical exercises are typically related to eating disorders, but its relationship with ON is still a subject of debate. Other transdiagnostic features could be necessary to conceptualize and understand ON; in this way, low self-esteem is related to eating behavior but is not still extensively investigated in ON, and, to date, data are so heterogeneous that they do not allow us to understand if this is a psychological feature somehow associated with ON. The current study aimed to assess whether disordered eating attitudes, self-esteem, and physical activity are associated with ON in young adults from Poland and Italy. Moreover, we investigated the differences by comparing lower and higher ON levels related to disordered eating attitudes, self-esteem, and physical activity. Our results indicated that a great concern about dieting significantly predicted problems associated with healthy eating, knowledge about healthy eating, and feeling positive about healthy eating. In addition, young adults with a high level of ON demonstrated higher levels of disordered eating attitudes and vigorous-intensity physical activity than young adults with a low level of ON. Future studies are needed to assess the direct effect of physical activity and self-esteem on ON.     

The Menstrual Cycle and Sexual Behavior: Relationship to Eating,Exercise, Sleep,and Health Patterns

ABSTRACT

Patterns of eating, exercise, sleep, and health were investigated across 180 menstrual cycles of 89 women who engaged in sex with a male (n = 45; cycles = 85), a female (n = 21; cycles = 37), or abstained from sex (n = 33; cycles = 58) from January 2005 to December 2007 (10 contributed to 2 groups). Cycles were divided into 5 phases based on their luteinizing hormone surges. Daily questionnaires and saliva for IgA and cortisol analyses were obtained. Women indicated that they ate more (p < .008) and did not sleep as well (p = .02) during their luteal and premenstrual phases. Participants were less likely to experience food cravings and did not satisfy their cravings when they were ovulatory (p < .001). Additionally, a greater proportion of lesbians skipped breakfast (p = .01) and exercised less than heterosexuals (p = .05). Sexually active women had lower cortisol and IgA levels than abstinent women (p = .02). Our study discovered, and confirmed, systematic differences in eating, sleeping, and health patterns across women's menstrual cycles.     

Physical activity and quality of life among university students: exploring self-efficacy,self-esteem,and affect as potential mediators

Purpose

Physical activity (PA) has been shown to enhance quality of life (QOL) in older adults. Findings from these studies indicate that the relationship between PA and QOL is indirect and likely mediated by variables such as physical self-esteem, exercise self-efficacy, and affect. As PA varies greatly by age, the purpose of the current study is to extend this area of research to young adults and explore the complex relationship between PA and QOL in this target population.

Methods

Data were collected via anonymous questionnaire from N = 590 undergraduate students. PA was assessed with the Godin Leisure Time Exercise Questionnaire, and QOL was assessed by the Satisfaction with Life Scale. Path analysis was used to test the relationship between PA and QOL, with mediators of exercise self-efficacy, physical self-esteem, and affect.

Results

The PA model (RMSEA = .03, CFI = .99) accounted for 25 % of the variance in QOL. PA had positive direct effects on exercise self-efficacy (β = .28, P < .001), physical self-esteem (β = .10, P < .001), positive affect (β = .10, P < .05), and negative affect (β = .08, P < .05). Physical self-esteem was found to be the most powerful mediating variable on QOL (β = .30, P < .001), followed by positive affect (β = .27, P < .001) and negative affect (β = .14, P < .001).

Conclusion

Physical self-esteem and, to a lesser extent, positive affect emerged as integral components in the link between PA and QOL. Findings suggest that health education programs designed to promote regular PA and increase physical self-esteem may be effective in improving QOL in young adults.     

2005-2008 Nutrition and Health Survey in Taiwan: the nutrition knowledge, attitude and behavior of 19-64 year old adults

The purpose of this study is to understand nutrition knowledge, attitude, and behavior in Taiwanese adults. Results indicated that adults' knowledge on 'relationship between diet and disease' and 'comparison of foods in terms of specific nutrients' is acceptable. However, they lack knowledge on 'daily serving requirements' and 'weight and weight loss'. Although they recognize the importance of nutrition, nutrition was not the major concern of food selection. Significant differences were found among gender and age groups. Females of most age groups are better than males in many aspects of nutrition knowledge, attitude and behavior except emotional and external eating behavior. Young (age 19-30) and prime (age 31-44) adults have better knowledge than that of middle adults (age 45-64), while prime adults hold a more positive attitude than young adults. As for nutrition behavior, prime and middle adults are better than young adults. Nutrition knowledge and attitude of adults in urban areas is generally better than those in suburban and remote areas. However, adults in urban areas perform 'emotional and external cued eating' more frequently than those in suburban and remote areas. There are significantly positive correlations among nutrition knowledge, attitude and behavior; and attitude has stronger correlation (r=0.42) with behavior than knowledge does (r=0.27). Therefore, to achieve desirable eating behaviors, the adult nutrition education program should include knowledge of what constitutes a balanced diet and what constitutes being overweight. Proper strategies to enhance the behavioral motivation of healthy food selection must also not be neglected.     

Racial comparisons in perceptions of maternal and peer attitudes,body dissatisfaction,and eating disorders among African American and White women

ABSTRACT

Although once thought primarily to affect White women, body dissatisfaction and disordered eating exist among all racial groups. In the current study, the authors determined whether the relationship between participants’ perceived maternal/peer attitudes toward appearance and the outcomes of body dissatisfaction and eating pathology varied by race. Self-reported data, including measures of body dissatisfaction, disordered eating behaviors, body mass index (BMI), and perceptions of maternal/peer attitudes, were collected from December 2012 to May 2013 at a large Mid-Atlantic university. BMI (β = 0.20, p = .01), perceptions of peers’ attitudes toward appearance (β = 0.23, p = .02), and White race (β = 0.33, p < .001) were independently associated with body dissatisfaction. Additionally, race interacted with perceptions of peers’ attitudes toward appearance such that at high perceptions, African American women reported high levels of body dissatisfaction (β = –0.20, p = .04), but this was not true for White women. Higher perceived peer concern about weight and shape (β = 0.32, p < .001), increased BMI (β = 0.30, p < .001), and White race (β = 0.21, p = .002), also were associated with disordered eating. The results of this study have implications for prevention programs that address disordered eating for racially diverse groups of women.     

Receipt of Preventive Health Services in Young Adults

PurposeTo examine self-reported rates and disparities in delivery of preventive services to young adults.MethodsA population-based cross-sectional analysis, of 3,670 and 3,621 young adults aged 18–26 years who responded to California Health Interview Survey (CHIS) in 2005 and CHIS 2007, respectively. The main outcome measures were self-reported receipt of flu vaccination, sexually transmitted disease (STD) screening, cholesterol screening, diet counseling, exercise counseling, and emotional health screening. Multivariate logistic regression was used to examine how age, gender, race/ethnicity, income, insurance, and usual source of care influence the receipt of preventive services.ResultsDelivery rates ranged from 16.7% (flu vaccine) to 50.6% (cholesterol screening). Being female and having a usual source of care significantly increased receipt of services, with female participants more likely to receive STD screening (p < .001), cholesterol screening (p < .01), emotional health screening (p < .001), diet counseling (p < .01), and exercise counseling (p < .05) than male participants after controlling for age, race/ethnicity, income, insurance, and usual source of care. Young adults with a usual source of care were more likely to receive a flu vaccine (p < .05), STD screening (p < .01), cholesterol screening (p < .001), diet counseling (p < .05), and exercise counseling (p < .05) than those without a usual source of care after adjusting for age, race/ethnicity, income, and insurance.ConclusionsRates of preventive services delivery are generally low. Greater efforts are needed to develop guidelines for young adults to increase the delivery of preventive care to this age-group, and to address the gender and ethnic/racial disparities in preventive services delivery.     

Self-compassion and intuitive eating in college women: Examining the contributions of distress tolerance and body image acceptance and action

Self-compassion has been linked to higher levels of psychological well-being. The current study evaluated whether this effect also extends to a more adaptive food intake process. More specifically, this study investigated the relationship between self-compassion and intuitive eating among 322 college women. In order to further clarify the nature of this relationship this research additionally examined the indirect effects of self-compassion on intuitive eating through the pathways of distress tolerance and body image acceptance and action using both parametric and non-parametric bootstrap resampling analytic procedures. Results based on responses to the self-report measures of the constructs of interest indicated that individual differences in body image acceptance and action (β = .31, p < .001) but not distress tolerance (β = .00, p = .94) helped explain the relationship between self-compassion and intuitive eating. This effect was retained in a subsequent model adjusted for body mass index (BMI) and self-esteem (β = .19, p < .05). Results provide preliminary support for a complementary perspective on the role of acceptance in the context of intuitive eating to that of existing theory and research. The present findings also suggest the need for additional research as it relates to the development and fostering of self-compassion as well as the potential clinical implications of using acceptance-based interventions for college-aged women currently engaging in or who are at risk for disordered eating patterns.     

Activities with Higher Influence on Quality of Life in Older Adults in Japan

The present study aimed to investigate the influence of 10 activities on quality of life (QOL) in Japanese older adults and to verify which activities had higher influence on QOL level. The subjects were 465 Japanese community‐dwelling older adults. QOL was assessed by the brief version of the World Health Organization Quality of Life (WHOQOL‐BREF) and the complementary assessment to measure the QOL of older adults (WHOQOL‐OLD) module. Activity and participation were measured through a questionnaire concerning frequency of engagement in several activities. The activity with the highest influence on WHOQOL‐BREF was physical activity (β = 0.209, p < 0.01), followed by art activity (β = 0.169, p < 0.01) and reading and writing (β = 0.141, p < 0.01). The activity with the highest influence on WHOQOL‐OLD was social activity (β = 0.222, p < 0.01), followed by reading and writing activity (β = 0.118, p < 0.05). The limitations of this study were the proportion of subjects and the place of recruitment. Further studies investigating in deep the relation between QOL and activity and participation, and other subjective and environmental factors that may influence the QOL are still needed among a higher and homogeneous subjects sample.

Understanding African American Women's Decisions to Buy and Eat Dark Green Leafy Vegetables: An Application of the Reasoned Action Approach

ObjectiveExamine intentions to buy and eat dark green leafy vegetables (DGLV).DesignCross-sectional survey assessing demographics, behavior, intention, and Reasoned Action Approach constructs (attitude, perceived norm, self-efficacy).SettingMarion County, Indiana.ParticipantsAfrican American women responsible for buying and preparing household food.Main Outcome Measure(s)Reasoned Action Approach constructs explaining intentions to buy and eat DGLV.AnalysisSummary statistics, Pearson correlations, and multiple regression analyses.ResultsAmong participants (n = 410, mean age = 43 y), 76% and 80%, respectively, reported buying and eating DGLV in the past week. Mean consumption was 1.5 cups in the past 3 days. Intentions to buy (r = 0.20, P < .001) and eat (r = 0.23, P < .001) DGLV were positively associated with consumption. Reasoned Action Approach constructs explained 71.2% of the variance in intention to buy, and 60.9% of the variance in intention to eat DGLV. Attitude (β = .63) and self-efficacy (β = .24) related to buying and attitude (β = .60) and self-efficacy (β = .23) related to eating DGLV explained significant amounts of variance in intentions to buy and eat more DGLV. Perceived norm was unrelated to either intention to buy or eat DGLV.Conclusions and ImplicationsInterventions designed for this population of women should aim to improve DGLV-related attitudes and self-efficacy.     

Instant Oatmeal Increases Satiety and Reduces Energy Intake Compared to a Ready-to-Eat Oat-Based Breakfast Cereal: A Randomized Crossover Trial

Background: Foods that enhance satiety can help consumers to resist environmental cues to eat and help adherence to calorie restriction. The objective of this study was to compare the effect of 2 oat-based breakfast cereals on appetite, satiety, and food intake.

Methods: Forty-eight healthy individuals, 18 years of age or older, were enrolled in a randomized, crossover trial. Subjects consumed isocaloric servings of either oatmeal or an oat-based ready-to-eat breakfast cereal (RTEC) in random order at least a week apart. Visual analogue scales measuring appetite and satiety were completed before breakfast and throughout the morning. Lunch was served 4 hours after breakfast. The physicochemical properties of oat soluble fiber (β-glucan) were determined. Appetite and satiety responses were analyzed by area under the curve. Food intake and β-glucan properties were analyzed using t tests.

Results: Oatmeal increased fullness (p = 0.001) and reduced hunger (p = 0.005), desire to eat (p = 0.001), and prospective intake (p = 0.006) more than the RTEC. Energy intake at lunch was lower after eating oatmeal compared to the RTEC (p = 0.012). Oatmeal had higher viscosity (p = 0.03), β-glucan content, molecular weight (p < 0.001), and radius of gyration (p < 0.001) than the RTEC.

Conclusions: Oatmeal suppresses appetite, increases satiety, and reduces energy intake compared to the RTEC. The physicochemical properties of β-glucan and sufficient hydration of oats are important factors affecting satiety and subsequent energy intake.
