A Group-Based, Six-Lesson Healthy Eating Curriculum for Individuals With Serious Mental Illnesses: Development and Implementation. Community Ment Health J 2024; 60:1352-1363. [PMID: 38865032 DOI: 10.1007/s10597-024-01291-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Accepted: 05/10/2024] [Indexed: 06/13/2024]
Abstract
As part of an intervention tailored to individuals with serious mental illnesses in residential settings that aimed to increase dietary intake of fresh vegetables and fruits, we developed and implemented a nutrition and cooking curriculum. To develop the curriculum, we assembled a Workgroup that consisted of professionals from multiple fields. The Workgroup held weekly discussions before drafting what would become the Workbook. Residential staff at partnering housing agencies taught the curriculum to residents. The curriculum Workbook contains six lessons, which are organized around two field trips to a mobile farmers market and a grocery store, and four cooking methods. The Workbook also includes instructions on using FreshConnect Checks at mobile farmers markets. The new curriculum distinguishes itself from other nutrition and culinary literacy curricula in that it delivers knowledge about fresh produce and skills in preparing fruits and vegetables in a way that is tailored to individuals with serious mental illnesses.

Demographic, clinical, and sociocognitive determinants related to physical activity and dietary intake in patients with ovarian cancer: A cross-sectional study. Gynecol Oncol 2024; 183:39-46. [PMID: 38503140 DOI: 10.1016/j.ygyno.2024.03.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Revised: 01/26/2024] [Accepted: 03/07/2024] [Indexed: 03/21/2024]
Abstract
OBJECTIVE To study physical activity and dietary intake among patients with ovarian cancer and to examine which demographic, clinical, and sociocognitive determinants are associated with these behaviours. METHODS This cross-sectional study included 139 patients with ovarian cancer scheduled for (neo)adjuvant chemotherapy. Physical activity was measured with the Physical Activity Scale for the Elderly questionnaire (PASE). Dietary intake was measured with a questionnaire assessing energy and protein intake and a questionnaire assessing adherence to the World Cancer Research Fund (WCRF) lifestyle recommendations. Demographic, clinical, and sociocognitive (e.g., self-efficacy) determinants of physical activity and dietary intake were examined using backward linear regression analyses. RESULTS Patients reported a median PASE score of 50 (IQR 24-94), a mean ± SD dietary intake of 1831 ± 604 kcal/day and 76 ± 27 g protein/day. Patients adhered to 3 out of 5 WCRF lifestyle recommendations. The absence of comorbidities, lower physical outcome expectations, and higher cancer specific outcome expectations were independently associated with higher physical activity levels. Higher age, lower cancer specific outcome expectations, and higher diet-related self-efficacy were significantly associated with adhering to more WCRF lifestyle recommendations, whilst no variables associated with total caloric or protein intake were identified. CONCLUSIONS Patients with ovarian cancer have low physical activity levels and a suboptimal diet, particularly low fruit and vegetable consumption and dietary fibre intake. Interventions aiming to improve physical activity and dietary intake could focus on increasing self-efficacy and outcome expectations, and should consider age and comorbidity as factors that may impact behaviour.

Su Y, Wu KC, Chien SY, Naik A, Zaslavsky O. A Mobile Intervention Designed Specifically for Older Adults With Frailty to Support Healthy Eating: Pilot Randomized Controlled Trial. JMIR Form Res 2023; 7:e50870. [PMID: 37966877 PMCID: PMC10687683 DOI: 10.2196/50870] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 10/10/2023] [Accepted: 10/19/2023] [Indexed: 11/16/2023] Open
Abstract
BACKGROUND Frailty, a common geriatric syndrome, predisposes older adults to functional decline. No medications can alter frailty's trajectory, but nutritional interventions may aid in supporting independence. OBJECTIVE This paper presents a pilot randomized controlled trial to investigate the feasibility and efficacy of a mobile health intervention, "Olitor," designed to enhance adherence to the Mediterranean diet among older adults with frailty, requiring no external assistance. METHODS The study sample consisted of 15 participants aged 66-77 (mean 70.5, SD 3.96) years randomized into intervention (n=8; 8 females; mean 72.4, SD 4.8 years) and control groups (n=7; 6 females, 1 male; mean 70.0, SD 3.9 years). The intervention involved a patient-facing mobile app called "Olitor" and a secure web-based administrative dashboard. Participants were instructed to use the app at least weekly for 3 months, which provided feedback on their food choices, personalized recipe recommendations, and an in-app messaging feature. Using Mann-Whitney tests to compare change scores and Hedges g statistics to estimate effect sizes, the primary efficacy outcomes were adherence to the Mediterranean diet score and insulin resistance measures. Secondary outcomes included retention as a measure of feasibility, engagement level and user app quality ratings for acceptability, and additional metrics to evaluate efficacy. Models were adjusted for multiple comparisons. RESULTS The findings demonstrated a significant improvement in the Mediterranean diet adherence score in the intervention group compared to the control (W=50.5; adjusted P=.04) with median change scores of 2 (IQR 2-4.25) and 0 (IQR -0.50 to 0.50), respectively. There was a small and insignificant reduction in homeostasis model assessment of insulin resistance measure (W=23; adjusted P=.85). Additionally, there were significant increases in legume intake (W=54; adjusted P<.01). The intervention's effect size was large for several outcomes, such as Mediterranean diet adherence (Hedges g=1.58; 95% CI 0.34-2.67) and vegetable intake (Hedges g=1.14; 95% CI 0.08-2.21). The retention rate was 100%. The app's overall quality rating was favorable with an average interaction time of 12 minutes weekly. CONCLUSIONS This pilot study revealed the potential of the mobile intervention "Olitor" in promoting healthier eating habits among older adults with frailty. It demonstrated high retention rates, significant improvement in adherence to the Mediterranean diet, and increased intake of recommended foods. Insulin resistance showed a minor nonsignificant improvement. Several secondary outcomes, such as lower extremity function and Mediterranean diet knowledge, had a large effect size. Although the app's behavior change features were similar to those of previous digital interventions, the distinctive focus on theory-informed mechanistic measures involved in behavioral change, such as self-regulation, self-efficacy, and expected negative outcomes, may have enhanced its potential. Further investigations in a more diverse and representative population, focusing on individuals with impaired insulin sensitivity, are warranted to validate these preliminary findings.

Abstract
Poor adherence to chronic disease treatment may seriously compromise the effectiveness of therapy, characterizing itself as a critical element for the population's health, both from the point of view of quality of life and health economics. The causes of low adherence are many and can depend on the patient, the physician and the healthcare system. Low adherence to dietary recommendations and lipid-lowering drug therapy for hypercholesterolemia is a widespread phenomenon that may strongly limit the great advantages of serum lipid reduction strategies in primary and secondary cardiovascular prevention. Many patients discontinue treatment, and adherence decreases with time. Increasing therapeutic adherence can have a much greater impact on the health of the population than any other therapeutic advance. There are numerous strategies to increase therapy adherence according to behavior change theories. They concern the doctor and the patient. Some must be implemented at the time of prescription, others later during the follow-up. The active role of the patient in the therapeutic decision and the shared definition of LDL cholesterol targets are of paramount importance. The aim of this narrative review is to summarize evidence on current levels of adherence to lipid-lowering strategies, the causes of the lack of adequate adherence and possible physician-applicable strategies to improve it.

Abstract
The purpose of this study was to compare the educational effects on nutrition knowledge of two teaching methods targeting adolescent male soccer players through learning online from WeChat account articles (WeChat group) or taking classroom courses (classroom group). The study investigates whether such teaching methods can improve self-efficacy and nutrition knowledge for athletes. A total of 41 U15 (age 15) youth male soccer players, 21 in the classroom group and 20 in the WeChat group, participated in the experiment by receiving the same nutrition education separately for 12 weeks. An athlete nutrition KAP questionnaire and self-efficacy questionnaire were conducted before the intervention, immediately after the intervention, and 6 weeks and 12 weeks after the intervention. As a result, the nutritional knowledge score and the total score of the athlete nutrition KAP questionnaire in the classroom group increased significantly and were notably higher than those in the WeChat group. Self-efficacy scores improved significantly in both groups. In conclusion, the study showed that the level of nutritional knowledge of U15 male soccer players was mediocre, and both forms of nutrition education can significantly improve the level of nutritional knowledge and self-efficacy of the players. In comparison, the educational effect of classroom teaching is significantly greater and more consistent than that of learning from WeChat public articles.

Abstract
Background The stay-at-home circumstances due to the global coronavirus pandemic have had some negative impacts on people's eating behavior. Purpose Therefore, this study attempted to improve fruit and vegetable (FV) consumption intention and behavior through an online video intervention based on the social cognitive theory. Methods Participants were recruited with a promotion video posted on social media channels. After consenting and completing a pre-survey, participants were randomly assigned to either a) the intervention group addressing FV consumption or the b) attention control group addressing physical activity. After two weeks, the participants completed an online post-survey. Results The participants (N = 82) were 77% female and 50% students; 95% chose German for the survey language, and 84% were from Switzerland. The mean baseline FV consumption intention was 3.05 (standard deviation: 1.03), and FV consumption was 4.64 (standard deviation: 2.06) portions a day. The analysis showed no significant change in FV consumption intention (F = (1, 78) = 0.02, p = 0.88, ηp2 = 0.00) or behavior (F = (1, 78) = 0.019, p = 0.89, ηp2 = 0.03) due to the intervention. Conclusions Plausible reasons why no significant effect was found were the brief intervention duration, the setting and insufficient tailoring. The lessons learned from this study are to plan better, tailor more to the needs of participants and carefully consider the goals before promoting an intervention.

Abstract
Nutrition interventions developed using behaviour theory may be more effective than those without theoretical underpinnings. This study aimed to document the number of theory-based healthy eating interventions, the involvement of dietitians/nutritionists and the behaviour theories employed from 2000 to 2020. We conducted a review of publications related to healthy eating interventions that used behaviour change theories. Interventional studies published in English between 2000 and 2020 were retrieved from searching Medline, Cinahl, Embase, Psycinfo and Cochrane Central. Citation, country of origin, presence or absence of dietitian/nutritionist authors, participants, dietary behaviours, outcomes, theories and any behaviour change techniques (BCTs) stated were extracted. The publication trends on a yearly basis were recorded. A total of 266 articles were included. The number of theory-based interventions increased over the two decades. The number of studies conducted by dietitians/nutritionists increased, but since 2012, increases have been driven by other researchers. Social cognitive theory was the most used behaviour theory. Dietitians/nutritionists contributed to growth in publication of theory-based healthy eating interventions, but the proportion of researchers from other professions engaged in this field increased markedly. The reasons for this growth in publications from other professions is unknown but conjectured to result from greater prominence of dietary behaviours within the context of an obesity epidemic.

Abstract
Background Few assessment tools exist for investigating perceived social support and self-efficacy behaviors in Arabic-speaking populations. Moreover, literature on the levels of social support and self-efficacy for adopting healthy eating and engaging in regular physical activity among Arabic-speaking young adults is currently lacking. This study aimed to adapt the Health Beliefs Survey Questionnaire (HBSQ) for Arabic-speaking populations and assess perceived social support and self-efficacy for adopting healthy eating and increased physical activity among university students. Methods In the first stage of the study, forward and backward translation and pretesting of the social support and self-efficacy scales of the HBSQ were conducted. The adapted questionnaire was administered to female university students (n = 258), and a subsample of 195 participants retook the questionnaire after 1 month. Construct validity was assessed with confirmatory factor analysis. The internal consistency of each subscale item was assessed by Cronbach’s alpha coefficient, and reproducibility was tested with intraclass correlation coefficients (ICCs) and Bland-Altman plots. In the second stage, the adapted questionnaire was used to assess the perceived social support and self-efficacy levels in a different sample of Arabic-speaking female university students (n = 283). Results Based on the results from confirmatory factor analysis, 6 items were selected for the social support scale and 19 items for the self-efficacy scale. The adapted questionnaire showed moderate to high internal reliability (Cronbach alpha coefficient = 0.681 to 0.900). The ICCs of the various subscales ranged from 0.666 to 0.997, indicating moderate to excellent reproducibility of the culturally adapted questionnaire. This was confirmed by Bland-Altman analysis. Participants in the second stage of the study reported significantly higher (P < 0.001) perceived support from family compared to friends in reducing sugar intake and increasing fiber consumption. Conclusions The results of the psychometric testing indicate the shortened Arabic HBSQ is a reliable tool for assessing perceived social support from family and close friends as well as for evaluating self-efficacy for choosing healthy foods and increasing physical activity among female university students.

Abstract
Providing simple information that identifies healthier/less healthy products at the point-of-sale has been increasingly recognized as a potential strategy for improving population diet. This review evaluated the effect on healthiness of food purchasing/intake of interventions that identify specific products as healthier/less healthy at the point-of-sale in food retail settings. Five databases were searched for peer-reviewed randomized controlled or quasi-experimental trials published 2000-2020. Effects on primary outcomes of the 26 eligible studies (322 stores and 19,002 participants) were positive (n = 14), promising (effective under certain conditions; n = 3), mixed (different effect across treatment arms/outcomes; n = 4), null (n = 3), negative (n = 1), or unclear (n = 1). Shelf-label studies (three studies of two rating systems across all products) were positive. Technology-delivered (mobile applications/podcast/kiosk) interventions were positive (n = 3/5) or promising/mixed (n = 2/5). In-store displays (n = 16) had mixed effectiveness. Interventions provided information on targeted healthier products only (n = 17), unhealthy products only (n = 1), both healthy and unhealthy (n = 2), and across all products (n = 5). No patterns were found between behavior change technique used and effectiveness. Study quality was mixed. These findings indicate that point-of-sale interventions identifying healthy/unhealthy options can lead to healthier customer purchasing behavior, particularly those delivered using shelf-labels or technology. Further research on discouraging unhealthy foods is needed.

Abstract
Purpose: The Social Cognitive Theory (SCT) suggests health behaviour can be modified by enhancing knowledge of health benefits and outcome expectations of changing behaviour, improving self-efficacy (confidence), and developing goals to overcome barriers to behaviour change. This study aimed to determine the impact of student-led nutrition workshops on participants' confidence related to SCT constructs for making dietary choices that align with evidence-based nutrition recommendations.Methods: Level-4 Science students developed and delivered 9 workshops on nutrition recommendations for the prevention and management of age-related diseases. Participants attending the workshops completed pre- and post-surveys to assess SCT constructs. For each SCT construct, participants rated their confidence on a 10-point Likert scale. The number (%) of participants who rated their confidence as ≥8/10 on the pre- and post-surveys were compared using the χ2 test.Results: Sixty-three community members (60% female, mean ± SD age 71 ± 7 years) attended the workshops. The number of participants rating confidence as ≥8/10 for each SCT construct increased after the workshops (P < 0.05).Conclusion: Undergraduate students can positively influence community members' confidence for making nutrition-related decisions. Involving students in interventions where SCT-structured workshops are used may help conserve health care resources and reach older adults who may not have access to dietitian services.

Efficiency of In-Store Interventions to Impact Customers to Purchase Healthier Food and Beverage Products in Real-Life Grocery Stores: A Systematic Review and Meta-Analysis. Foods 2021; 10:922. [PMID: 33922185 PMCID: PMC8146080 DOI: 10.3390/foods10050922] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Revised: 04/19/2021] [Accepted: 04/19/2021] [Indexed: 11/30/2022] Open
Abstract
Grocery stores are important settings to promote healthier food and beverage choices. The present paper aims at reviewing the effectiveness of different types of in-store interventions and how they impact sales of different product category in real grocery stores. Systematic search was conducted in six databases. In-store interventions were categorized according to the framework by Kraak et al. (2017) into one or more of eight interventions (e.g., place, profile, portion, pricing, promotion, healthy default picks, prompting and proximity). This systematic theme-based review follows the preferred reporting items for systematic reviews and meta-analyses (PRISMA) data screening and selection. Thirty-six studies were included in the qualitative synthesis and 30 studies were included in the meta-analysis, representing 72 combinations of in-store interventions. The analysis demonstrates that interventions overall had small significant effect size (ES) using Cohen's d on food purchase behavior (d = 0.17, 95% CI [0.04, 0.09]), with largest ES for pricing (d = 0.21) and targeting fruits and vegetables (d = 0.28). Analysis of ES of in-store interventions show that pricing, and pricing combined with promotion and prompting, effectively impacted purchase behavior. Interventions significantly impacted both sales of healthy and unhealthy products and significantly increased sales of fruits and vegetables, healthy beverage and total volume of healthy products. Results should however be interpreted with some caution, given the relatively low quality of overall evidence and low number of studies and observations for some types of intervention. Further research exploring impact on different in-store interventions and targeting especially unhealthy products are needed.

Design of the GOT Doc study: A randomized controlled trial comparing a Guided Self-Help obesity treatment program for childhood obesity in the primary care setting to traditional family-based behavioral weight loss. Contemp Clin Trials Commun 2021; 22:100771. [PMID: 33997462 PMCID: PMC8095104 DOI: 10.1016/j.conctc.2021.100771] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Revised: 03/11/2021] [Accepted: 04/05/2021] [Indexed: 11/26/2022] Open
Abstract
Currently one-third of children in the United States have overweight or obesity (OW/OB). The goal of Healthy People 2020 is to reduce the proportion of children with OW/OB and increase the proportion of primary care visits that include nutrition and weight-related counseling. Unfortunately, many health care providers find it difficult to offer effective weight-related counseling and treatment in the primary care setting. Therefore, new models of care are needed that allow a greater proportion of children with OW/OB and their parents to access care and receive quality weight management treatment. The current paper describes the GOT Doc study which is designed to test the effectiveness of a Guided Self-Help (GSH) model of obesity treatment that can be delivered in the primary care setting compared to a traditional Family-Based Behavioral weight loss treatment (FBT) delivered at an academic center. We will assess the impact of this program on attendance (access to care) and changes in child BMI percentile/z-score. We will also examine the impact of this treatment model on change in child lifestyle behaviors, parent support behaviors, and parent self-efficacy and empowerment to make behavior change. Finally, we will assess the cost-effectiveness of this model on changes in child BMI percentile/z-score. We believe the GSH intervention will be a cost-effective model of obesity management that can be implemented in community practices around the country, thereby increasing access to treatment for a broader proportion of our population and decreasing rates of childhood obesity. Effective childhood obesity treatment is not widely available or easily accessible. Guided Self-Help (GSH) model of treatment has been developed for pediatric obesity. GSH is easier to implement and can be delivered in the primary care setting. GSH can increase access to much needed treatment. Evaluation of its effectiveness in the primary care setting is needed.

Abstract
The present study examined the association between outcome expectations, self-efficacy, and intention to disclose HIV status to children among HIV-positive women in China, and the moderating and mediating role of self-efficacy on the association between outcome expectations and intention to disclose. A cross-sectional survey was conducted among 179 HIV-positive mothers who had at least one living child aged >5 years and had not yet disclosed their HIV status to her oldest child. Results from hierarchical regressions revealed that after adjusting for socio-demographic and medical variables, negative outcome expectations had a negative association (β = -0.22), while disclosure self-efficacy had a positive association (β = 0.43) with an intention to disclose HIV. The moderation effect of self-efficacy on the association between outcome expectations and intention to disclose HIV was not significant. Results from structural equation modeling showed that self-efficacy mediated the association between negative/positive outcome expectations and intention to disclose HIV. Findings support the importance of outcome expectations and self-efficacy and also the mediating role of self-efficacy in HIV disclosure among HIV-positive mothers in the Chinese context.

Abstract
Prevention strategies for non-communicable diseases (NCDs) are a global priority as it has been estimated that NCDs will account for around 73% of worldwide mortality by the year 2020. The adoption of diets that are low in saturated fat, free sugars, and red and processed meats and higher in unsaturated fats, wholegrains, fruit, and vegetables have been shown to reduce the risk of NCDs. With increasing internet use, several nutrition interventions are now being conducted online as well as face-to-face, however it is unclear which delivery method is most effective. Although a consumer preference toward face-to-face dietary advice delivery has been identified previously, interest in delivering web-based dietary advice, and in particular personalized nutrition (PN), has been rising, as internet delivery may be less costly and more scalable. This review compares published face-to-face and web-based dietary interventions to give insight into which dietary method might be more effective for PN. In total, 19 peer-reviewed randomized controlled trials were identified for inclusion in the review. The majority of face-to-face nutrition interventions were successful at facilitating dietary change. Results from web-based nutrition interventions suggested that personalized web-based nutrition interventions may be successful at inducing short-term dietary change compared to standardized dietary interventions, however, minimal evidence of long-term impact has been found across both delivery methods. Results of a trial that compared face-to-face with web-based diet intervention found significantly greater dietary changes in the face-to-face group compared to web-based and control groups. Further controlled comparative studies and cost-benefit analysis are needed to assess whether web-based methods can be used in place of face-to-face interventions for achieving dietary change.

Abstract
BACKGROUND One of the main occupational hazards for seafarers is the long exposure to sunlight. This study aimed to determine the efficacy of a mobile phone-based text message intervention in adopting skin cancer preventive behaviors among a sample of seafarers in Genaveh port located in Bushehr province, Iran. METHODS In this randomized controlled trial, 136 seafarers were randomly selected and assigned to the intervention (n = 68) or a control groups (n = 68). As a theoretical basis, we followed the Protection Motivation Theory (PMT) variables to develop the text messages. The data related to PMT variables and skin cancer preventive behaviors were collected through a questionnaire. Forty-five text messages were designed, pre-tested and sent to the seafarers' phones in the intervention group in 45 days. Both groups were followed up 1 month after the intervention. Data collected in the two stages were analyzed using paired-samples t-test, ANCOVA, and Chi-square tests. RESULTS Following the intervention, the mean scores of adopting skin cancer preventive behaviors (p = 0.001), perceived self-efficacy (p = 0.01), protection motivation (p = 0.02), and fear (p = 0.001) were significantly higher in the intervention group than the control group. There was significant reduction in the response costs (p = 0.05) and perceived rewards (p = 0.01) scores in the intervention group compared with the control group after the intervention. However, there were no significant differences in the perceived vulnerability (p = 0.14), perceived severity (p = 0.09), and response efficacy (p = 0.64) between the two groups after the intervention. CONCLUSIONS The results of the study indicated the effectiveness of mobile phone-based text message intervention for increasing skin cancer preventive behaviors in Iranian seafarers.

Abstract
Context Cardiovascular disease (CVD) is the leading cause of death in the United States, and cardiovascular events have been shown to be reduced and prevented when patients follow the Mediterranean diet. Objective To understand how familiarity with the Mediterranean diet affects dietary habits in cardiology patients by using social cognitive theory. Method This cross-sectional study included patients at a metropolitan outpatient cardiology clinic in Oklahoma. A survey was used to analyze patient knowledge of the Mediterranean diet. Patients were separated into low-, medium-, and high-diet adherence groups based on their daily consumption of fruits, vegetables, fish, whole grains, and nuts. Multinomial logistic regression was used to analyze patients' knowledge of Mediterranean diet principles with dietary adherence. Results A total of 337 patients were included in the study. Patients with a college education, patients reporting familiarity with the diet, and women were 6.7, 4.0, and 3.2 times as likely, respectively, to have strong adherence to the Mediterranean diet. Conclusion The finding that familiarity with the Mediterranean diet was closely associated with adherence to its principles indicates that patient education on heart-healthy diets may improve the eating habits of patients, especially patients at risk for cardiac events.

Abstract
Self-efficacy is an important determinant of health behaviour. Digital interventions are a potentially acceptable and cost-effective way of delivering programmes of health behaviour change at scale. Whether behaviour change interventions work to increase self-efficacy in this context is unknown. This systematic review and meta-analysis sought to identify whether automated digital interventions are associated with positive changes in self-efficacy amongst non-clinical populations for five major health behaviours, and which BCTs are associated with that change. A systematic literature search identified 20 studies (n = 5624) that assessed changes in self-efficacy and were included in a random-effects meta-analysis. Interventions targeted: healthy eating (k = 4), physical activity (k = 9), sexual behaviour (k = 3) and smoking (k = 4). No interventions targeting alcohol use were identified. Overall, interventions had a small, positive effect on self-efficacy (g¯=0.190,CI[0.078;0.303]). The effect of interventions on self-efficacy did not differ as a function of health behaviour type (Q-between = 7.3704, p = .061, df = 3). Inclusion of the BCT 'information about social and environmental consequences' had a small, negative effect on self-efficacy (Δg¯=-0.297,Q=7.072,p=.008). Whilst this review indicates that digital interventions can be used to change self-efficacy, which techniques work best in this context is not clear.

Abstract
Cancer patients and survivors are at risk of poor clinical outcomes due to poor nutritional intake following cancer diagnosis. During cancer treatment, treatment toxicities can affect eating patterns and can lead to malnutrition resulting in loss of lean body mass and excessive weight loss. Following treatment and throughout survivorship, patients are at risk of not meeting national nutrition guidelines for cancer survivors, which can affect recurrence and survival. Obesity, which is highly prevalent in cancer patients and survivors, can affect clinical outcomes during treatment by masking malnutrition and is also a risk factor for cancer recurrence and poorer survival in some cancers. Appropriate and effective nutritional education and guidance by trained clinicians are needed throughout the cancer continuum. This article presents an overview of recommendations and guidelines for nutrition and weight management and provides recent examples of behavioral theory-based targeted lifestyle interventions designed to increase adherence to recommendation by cancer patients and survivors.

Abstract
Background. An adequate intake of fruits and vegetables (FVI) has shown benefits for reduced risk of manifesting chronic diseases. Thus, development of effective interventions to promote FVI is paramount. Aim. To assess the effectiveness of eHealth interventions for FVI targeted to healthy population, in comparison with control groups, and identify the moderators contributing to their effectiveness. Method. A database search was conducted in April 2016 and July 2018 using MEDLINE, PsycINFO, ERIC, Google Scholar, SciELO, and RISS, yielding 19 eligible studies. Risk of bias was assessed using Cochrane's Risk of Bias Tool. Random-effects model was used to calculate effect sizes (ES) by weighted standardized mean differences. Results. This meta-analysis includes 19 studies and 6,894 participants. The most common eHealth tool used was Internet-based interventions (n = 10). Most of studies were conducted in adults (n = 11), followed by children (n = 4), and adolescents (n = 4). The minimum number of behavior change techniques (BCTs) used was one, and the maximum seven. The overall ES was small (0.26, p < .001), favoring eHealth interventions. The between-studies heterogeneity was large (I2 = 62.77%, p < .001). Subgroup analyses showed that the components with larger ES were tailored interventions (0.27, p < .001), computer-based interventions (0.44, p < .001), and use of ≥7 BCTs (0.42, p < .001). Discussion. All studies showed a positive ES favoring interventions. Large heterogeneity could be explained in part by the number of BCTs and type of eHealth tool used. Nonetheless, more concrete evidence regarding other intervention components effectiveness was limited by small sample size. Conclusion. The use of eHealth tools for the improvement of FVI showed to be more effective compared with nonintervention and interventions not using these technologies. Nonetheless, more research is needed to determine the specific combination of intervention components that could translate into larger effectiveness.

Abstract
Effectiveness of using visual approaches in health education and its influential factors were still in debate. This study aimed to asess the effects of visualized nutrition education on dietary knowledge and behavioral changes, and factors influencing them. A comprehensive search of PubMed, EMBASE, Scopus, and Cochrane Library was conducted. Eligible studies were trials assessed effects of visualized nutrition education on dietary knowledge or behavior changes, compared with non-visualized or no education group. Fourteen studies (n = 7,259) were qualitatively analyzed and 7 of them were included in the meta-analysis. We found a higher fiber intake in both short term (1.59 g/1000 kcals, 95% CI 0.90-2.27) and long term (1.36 g/1000 kcals, 95% CI 0.64-2.09). A marginal advantage was shown in short-term fruits and vegetables consumption (F&V consumption) (standardized mean difference [SMD] = 0.08, 95% CI -0.00 to 0.16). The education effects were more pronounced when education was delivered in series (SMDF&V consumption = 0.09, 95% CI 0.00-0.17), avoiding loss-framing (SMDFat intake = 0.31, 95% CI 0.10-0.51) and video modeling (SMDF&V consumption = 0.23, 95% CI 0.03-0.43), with short length plus cultural adaptation. Visualized nutrition education was overall promising in improving dietary behaviors. Delivering in series, short in length, with cultural adaptation were features tended to enlarge the benefits of visualized education while loss-framing and video modeling might be avoided.

Abstract
INTRODUCTION Diabetes is one of the most common chronic diseases among the elderly and is also a very serious health problem. Adopting theory-based self-care behaviors is an effective means in managing such diseases. This study aimed to determine the predictors of diabetes self-care in the elderly in Kerman based on a social cognitive theory. MATERIAL AND METHODS In this cross-sectional study, 384 elderly diabetic patients who had referred to health screening centers in Kerman were chosen via cluster sampling. To collect information about self-care and its predictors, Toobert Glasgow's diabetes self-efficacy scale as well as a questionnaire was used which was based on social cognitive theory constructs. The validity and reliability of the questionnaire was confirmed. The data were analyzed using Pearson correlation and linear regression analysis in SPSS software 17. FINDINGS Among the subjects, 67.37% (252) had poor self-care ability; 29.14% (109) had average ability, and 3.40% (13) enjoyed a proper level of self- care ability. There was a significant relationship between the constructs of the social cognitive theory (knowledge, self- efficacy, social support, outcome expectations, outcome expectancy and self-regulation) and the self-care score. Furthermore, the mentioned constructs could predict 0.47% of the variance of the self-care behaviors. CONCLUSION self-care behaviors in this study were poor. Therefore, it is necessary to develop an educational intervention based on cognitive theory constructs with the goal of properly managing diabetes in the elderly patients.

Abstract
OBJECTIVES To compare changes in food-purchasing knowledge, self-efficacy, and behavior after viewing nutrition education videos among Los Angeles, California Latinas responsible for household grocery shopping. METHODS From February to May 2015, a convenience sample of 113 Latinas watched 1 video (El Carrito Saludable) featuring MyPlate guidelines applied to grocery shopping (1-video intervention) and another convenience sample of 105 Latinas watched 2 videos (El Carrito Saludable and Ser Consciente), the latter featuring mindfulness to support attention and overcome distractions while grocery shopping (2-video intervention). We administered questionnaires before and after intervention. A preselected sample in each intervention condition (n = 72) completed questionnaires at 2-months after intervention and provided grocery receipts (before and 2-months after intervention). RESULTS Knowledge improved in both intervention groups (P < .001). The 2-video group improved more in self-efficacy and use of a shopping list (both P < .05) and purchased more healthy foods (d = 0.60; P < .05) at 2 months than did the 1-video group. CONCLUSIONS Culturally tailored videos that model food-purchasing behavior and mindfulness show promise for improving the quality of foods that Latinas bring into the home.

Abstract
Diet-related mobile apps hold promise in helping individuals self-regulate their eating behaviors. Nevertheless, little is known about the extent to which diet-related mobile apps incorporate the established behavior change theories and evidence-based practices that promote dietary self-regulation. Guided by the self-regulation aspect of Bandura's social cognitive theory and the Dietary Guidelines for Americans 2010 of the U.S. Department of Agriculture, this study conducts a content analysis of diet-related mobile apps for iPhone (N = 400). In terms of the adherence to the self-regulation aspect of the social cognitive theory, results show that although 72.5% of the apps incorporate at least one theoretical construct, few apps tap all three processes of self-regulation (i.e., self-observation/monitoring, judgment process, and self-reaction). Additionally, outcome expectation is manifested in a majority of the diet-related apps. In terms of the Dietary Guidelines for Americans 2010, while the diet-related apps equally emphasize setting goals for calorie intake or nutrient consumption, more apps feature nutrient tracking than calorie tracking. Implications and limitations are discussed.

Abstract
We developed a theory-based dietary change curriculum for Hispanic breast cancer survivors with the goal of testing the effects of the intervention on change in dietary intake of fruits/vegetables and fat in a randomized, clinical trial. Social cognitive theory and the transtheoretical model were used as theoretical frameworks to structure curriculum components using the Nutrition Education DESIGN Procedure. Formative assessments were conducted to identify facilitators and barriers common to Hispanic women and test the degree of difficulty and appropriateness of program materials. Focus groups provided valuable insight and informed preimplementation modifications to the dietary program. The result was a systematically planned, evidence-based, culturally tailored dietary intervention for Hispanic breast cancer survivors, ¡Cocinar Para Su Salud! (Cook for Your Health!). The methodology described here may serve as a framework for the development of future dietary interventions among diverse and minority populations. Short- and long-term study results will be reported elsewhere.

Abstract
OBJECTIVE The Make Better Choices 1 trial demonstrated that participants with unhealthy diet and activity behaviors who were randomized to increase fruits/vegetables and decrease sedentary leisure achieved greater diet and activity improvement than those randomized to change other pairs of eating and activity behaviors. Participants randomized to decrease saturated fat and increase physical activity achieved the least diet-activity improvement. This study examined which psychological mechanisms mediated the effects of the study treatments on healthy behavior change. METHODS Participants (n = 204) were randomized to 1 of 4 treatments: increase fruits/vegetables and physical activity; decrease saturated fat and sedentary leisure; decrease saturated fat and increase physical activity; increase fruits/vegetables and decrease sedentary leisure. Treatments provided 3 weeks of remote coaching supported by mobile decision support technology and financial incentives. Mediational analyses were performed to examine whether changes in positive and negative affect, and self-efficacy, stages of readiness to change, liking, craving and attentional bias for fruit/vegetable intake, saturated fat intake, physical activity, and sedentary leisure explained the impact of the treatments on diet-activity improvement. RESULTS Greater diet-activity improvement in those randomized to increase fruits/vegetables and decrease sedentary leisure was mediated by increased self-efficacy (indirect effect estimate = 0.04; 95% bias corrected CI, 0.003-0.11). All treatments improved craving, stage of change and positive affect. CONCLUSION Accomplishing healthy lifestyle changes for 3 weeks improves positive affect, increases cravings for healthy foods and activities, and enhances readiness to make healthy behavior changes. Maximal diet and activity improvement occurs when interventions enhance self-efficacy to make multiple healthy behavior changes. (PsycINFO Database Record

Abstract
BACKGROUND This study explored whether the determinants that were targeted in two versions of a Web-based computer-tailored nutrition education intervention mediated the effects on fruit, high-energy snack, and saturated fat intake among adults who did not comply with dietary guidelines. METHOD A RCT was conducted with a basic (tailored intervention targeting individual cognitions and self-regulation), plus (additionally targeting environmental-level factors), and control group (generic nutrition information). Participants were recruited from the general Dutch adult population and randomly assigned to one of the study groups. Online self-reported questionnaires assessed dietary intake and potential mediating variables (behavior-specific cognitions, action- and coping planning, environmental-level factors) at baseline and one (T1) and four (T2) months post-intervention (i.e. four and seven months after baseline). The joint-significance test was used to establish mediating variables at different time points (T1-mediating variables - T2-intake; T1-mediating variables - T1-intake; T2-mediating variables - T2-intake). Educational differences were examined by testing interaction terms. RESULTS The effect of the plus version on fruit intake was mediated (T2-T2) by intention and fruit availability at home and for high-educated participants also by attitude. Among low/moderate-educated participants, high-energy snack availability at home mediated (T1-T1) the effect of the basic version on high-energy snack intake. Subjective norm mediated (T1-T1) the effect of the basic version on fat intake among high-educated participants. DISCUSSION Only some of the targeted determinants mediated the effects of both intervention versions on fruit, high-energy snack, and saturated fat intake. A possible reason for not finding a more pronounced pattern of mediating variables is that the educational content was tailored to individual characteristics and that participants only received feedback for relevant and not for all assessed mediating variables.

Abstract
This study explores how people respond to images of junk versus healthy food as a function of their eating habits and food knowledge. The experiment reported here proposed and tested the idea that those with unhealthy eating habits but highly knowledgeable about healthy eating would feel more positive and also more negative toward junk food images compared to images of healthy food because they may perceive them as risky--desirable but potentially harmful. The psychophysiological data collected from participants during their exposure to pictures of junk versus healthy food supported this idea. In addition, unhealthy eaters compared to healthy eaters with the same degree of food knowledge responded more positively to all food items. The findings are critical from a health communication perspective. Because unhealthy eaters produce stronger emotional responses to images of junk food, they are more likely to process information associated with junk food with more cognitive effort and scrutiny. Thus, when targeting this group and using images of junk food, it is important to combine these images with strong message claims and relevant arguments; otherwise, if the arguments are perceived as irrelevant or weak, the motivational activation associated with junk food itself may transfer into an increased desire to consume the unhealthy product.

Abstract
PURPOSE This study aimed to test the usefulness of social cognitive theory (SCT) in explaining breakfast consumption in a sample of primary male students. METHODS Participants in this cross-sectional study were 358 male students (3rd, 4th and 5th grades) from eight public primary schools of Ilam city. Data were collected by a self-administered questionnaire based on components of SCT. Bivariate correlations and multiple logistic regression analysis using an Enter method were used to identify social cognitive correlates and determinants of breakfast consumption. RESULTS A total of 358 participants ranging in age from 8-12 years (M=10.06) were studied. The result of the study showed that the SCT significantly predicted breakfast consumption. SCT variables explained 41.4% of the variance in breakfast consumption behaviors, though, self-regulation was found to be the strongest predictor of breakfast consumption behaviors. There was the strongest correlation between behaviors and self-regulation, (r=0.561; P<0.001). CONCLUSION The findings support the usefulness of SCT in explaining breakfast consumption behaviors. These results suggest an essential role for self-regulation, self-efficacy and social support in the breakfast consumption behaviors of primary male students.

Abstract
More than 60% of cancer-related deaths in the United States are attributable to tobacco use, poor nutrition, and physical inactivity, and these risk factors tend to cluster together. Thus, strategies for cancer risk reduction would benefit from addressing multiple health risk behaviors. We adapted an evidence-based intervention grounded in social cognitive theory and principles of motivational interviewing originally developed for smoking cessation to also address physical activity and fruit/vegetable consumption among Latinos exhibiting multiple health risk behaviors. Literature reviews, focus groups, expert consultation, pretesting, and pilot testing were used to inform adaptation decisions. We identified common mechanisms underlying change in smoking, physical activity, and diet used as treatment targets; identified practical models of patient-centered cross-cultural service provision; and identified that family preferences and support as particularly strong concerns among the priority population. Adaptations made to the original intervention are described. The current study is a practical example of how an intervention can be adapted to maximize relevance and acceptability and also maintain the core elements of the original evidence-based intervention. The intervention has significant potential to influence cancer prevention efforts among Latinos in the United States and is being evaluated in a sample of 400 Latino overweight/obese smokers.

Abstract
Improving diet and other lifestyle behaviours has considerable potential for reducing the global burden of non-communicable diseases, promoting better health across the life-course and increasing wellbeing. However, realising this potential will require the development, testing and implementation of much more effective behaviour change interventions than are used conventionally. Evidence-based, personalised (or stratified) interventions which incorporate effective behaviour change techniques (BCT) and which are delivered digitally are likely to be an important route to scalable and sustainable interventions. Progress in developing such interventions will depend on the outcomes of research on: (i) the best bases for personalisation of dietary advice; (ii) identification of BCT which are proven to enhance intervention efficacy; (iii) suitable platforms (digital-based tools) for collection of relevant participant characteristics (e.g. socioeconomic information, current diet and lifestyle and dietary preferences) linked with intelligent systems which use those characteristics to offer tailored feedback and advice in a cost-effective and acceptable manner. Future research should focus on such interventions aiming to reduce health inequalities and to improve overall public health.

Abstract
BACKGROUND Point-of-sale is a potentially important opportunity to promote healthy eating through nutrition education and environment modification. The aim of this review was to describe and review the evidence of effectiveness of various types of interventions that have been used at point-of-sale to encourage purchase and/or eating of healthier food and to improve health outcomes, and the extent to which effectiveness was related to intensity, duration and intervention setting. METHODS Records from searches in databases were screened and assessed against inclusion criteria. Included studies had risk of bias assessed. Intervention effectiveness was assessed for two outcomes: i) purchase and/or intake of healthier food options and/or nutrient intake; and ii) mediating factors that might effect the primary outcome. RESULTS The search identified 5635 references. Thirty-two papers met the inclusion criteria. Twelve studies had low risk of bias and were classified as strong, nine were moderate and 11 were weak. Six intervention types and a range of different outcome measures were described in these papers: i) nutrition education and promotion alone through supermarkets/stores; ii) nutrition education plus enhanced availability of healthy food; iii) monetary incentive alone; iv) nutrition education plus monetary incentives; v) nutrition intervention through vending machines; and vi) nutrition intervention through shopping online. The evidence of this review indicates that monetary incentives offered to customers for a short-term look promising in increasing purchase of healthier food options when the intervention is applied by itself in stores or supermarkets. There was a lack of good quality studies addressing all other types of relevant point-of-sale interventions examining change in purchase and/or intake of healthier food options. There were few studies that examined mediating factors that might mediate the effect on the primary outcomes of relevant interventions. CONCLUSIONS A range of intervention types have been used at point-of-sale to encourage healthy purchasing and/or intake of healthier food options and to improve health outcomes. There is a need for more well designed studies on the effectiveness of a range of point-of-sale interventions to encourage healthier eating and improve health outcomes, and of the mediating factors that might impact these interventions.

Abstract
Podcasting is an emerging technology, and previous interventions have shown promising results using theory-based podcast for weight loss among overweight and obese individuals. This study investigated whether constructs of social cognitive theory and information processing theories (IPTs) mediate the effect of a podcast intervention on weight loss among overweight individuals. Data are from Pounds off Digitally, a study testing the efficacy of two weight loss podcast interventions (control podcast and theory-based podcast). Path models were constructed (n = 66). The IPTs, elaboration likelihood model, information control theory, and cognitive load theory mediated the effect of a theory-based podcast on weight loss. The intervention was significantly associated with all IPTs. Information control theory and cognitive load theory were related to elaboration, and elaboration was associated with weight loss. Social cognitive theory constructs did not mediate weight loss. Future podcast interventions grounded in theory may be effective in promoting weight loss.

Abstract
Background A wide range of self-directed weight-loss interventions are available, providing users with a variety of tools delivered through various formats to regulate weight-related behavior patterns. However, it is unclear how effective self-directed interventions are and how they promote weight loss and weight maintenance. Objective A systematic review of reviews was conducted to examine the effectiveness of such interventions and to identify intervention content associated with effectiveness. Methods MEDLINE, Embase, PsycINFO, CINAHL, and the Cochrane Library for systematic reviews were searched from 2000-2012 for reviews of the effectiveness of self-directed interventions on weight loss and weight maintenance in adults. Two reviewers used predefined inclusion criteria to select relevant reviews and assess their quality using the Overview Quality Assessment Questionnaire (OQAQ). We extracted data on effectiveness and on relationships between intervention characteristics and effectiveness. Results Twenty reviews were included and quality assessed. Findings relevant to self-directed interventions, including interactive websites, smartphone applications, and text messaging (short message service, SMS) were summarized. Findings were mixed but promising. For example, one review of Internet-based interventions found that, when used in conjunction with standard weight loss programs, these interventions resulted in a significant average increase in weight loss of 1.5 kg over evaluation periods. Unfortunately, only 7 of 20 reviews were of high methodological quality according to OQAQ scores, and only 4 employed meta-analyses. Few reviews linked intervention content to effectiveness. Conclusions Current evidence suggests that self-directed interventions can independently promote weight loss and can augment interventions involving personal contact. Particular change techniques and delivery modes including individualized feedback, email counseling, and online social support appear to enhance effectiveness. Further reviews of the content of self-directed weight-loss intervention studies are needed to clarify which change techniques delivered through which delivery formats optimize intervention effectiveness.

Consumer health information technology in an adult public health primary care clinic: a heart health education feasibility study. PATIENT EDUCATION AND COUNSELING 2013; 93:464-471. [PMID: 23948646 DOI: 10.1016/j.pec.2013.07.010] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/05/2012] [Revised: 07/11/2013] [Accepted: 07/14/2013] [Indexed: 06/02/2023]
Abstract
OBJECTIVE To explore the feasibility and short term outcomes of using an interactive kiosk integrated into office flow to deliver health information in a primary care clinic. METHODS Fifty-one adults with BMI ≥25 were randomly assigned to use a kiosk with attached devices to receive a six-week healthy eating/weight monitoring (intervention) or general health/BP monitoring (attention-control) program. Outcomes were measured at baseline, 8 weeks (post) and three month follow-up. RESULTS Participants completed an average of 2.73 weekly sessions, with transportation and time given as limiting factors. They found the kiosk easy to use (97%), liked the touchscreen (94%), and would use the kiosk again (81%). Although there were no differences between groups, the 27 completing all assessments showed reduced weight (p=.02), and decreased systolic (p=.01) and diastolic BP (p<.001) at follow-up. Although healthy eating behaviors increased, the change was not statistically significant. CONCLUSION Using a kiosk within a clinic setting is a feasible method of providing health information and self-monitoring. Multi-session educational content can provide beneficial short-term outcomes in overweight adults. PRACTICE IMPLICATIONS A kiosk with attached peripherals in a clinic setting is a viable adjunct to provider education, particularly in medically underserved areas.

Abstract
BACKGROUND Dietary fiber may decrease the risk of cardiovascular disease and associated risk factors. We examined trends in dietary fiber intake among diverse US adults between 1999 and 2010, and investigated associations between dietary fiber intake and cardiometabolic risks including metabolic syndrome, cardiovascular inflammation, and obesity. METHODS Our cross-sectional analysis included 23,168 men and nonpregnant women aged 20+ years from the 1999-2010 National Health and Nutrition Examination Survey. We used weighted multivariable logistic regression models to estimate predicted marginal risk ratios and 95% confidence intervals for the risks of having the metabolic syndrome, inflammation, and obesity associated with quintiles of dietary fiber intake. RESULTS Consistently, dietary fiber intake remained below recommended adequate intake levels for total fiber defined by the Institute of Medicine. Mean dietary fiber intake averaged 15.7-17.0 g. Mexican Americans (18.8 g) consumed more fiber than non-Hispanic whites (16.3 g) and non-Hispanic blacks (13.1 g). Comparing the highest with the lowest quintiles of dietary fiber intake, adjusted predicted marginal risk ratios (95% confidence interval) for the metabolic syndrome, inflammation, and obesity were 0.78 (0.69-0.88), 0.66 (0.61-0.72), and 0.77 (0.71-0.84), respectively. Dietary fiber was associated with lower levels of inflammation within each racial and ethnic group, although statistically significant associations between dietary fiber and either obesity or metabolic syndrome were seen only among whites. CONCLUSIONS Low dietary fiber intake from 1999-2010 in the US, and associations between higher dietary fiber and a lower prevalence of cardiometabolic risks suggest the need to develop new strategies and policies to increase dietary fiber intake.

Abstract
Comprehensive childhood obesity prevention (COP) strategies should include increasing school nurse involvement. This study was conducted to determine the influence of key school nurse perceptions (self-efficacy, perceived benefits, and perceived barriers) on participation in COP practices at the individual child and school level. Florida registered nurse (RN) school nurses (n = 171) anonymously completed online or paper questionnaires. Linear regression analyses identified a model of self-efficacy with perceived benefits and barriers that explained 12% and 9.1% (p < .001) of variance in child-level and school-level COP practices, respectively. Self-efficacy explained the most variance in both models (p < .001). Mediation testing identified perceived barriers as a partial mediator of the influence of self-efficacy on child-level practices. These findings support interventions and policy changes to increase self-efficacy and reduce perceived barriers to promote school nurse involvement in preventing childhood obesity.

Abstract
INTRODUCTION Increasingly high rates of obesity have heightened interest among researchers and practitioners in identifying evidence-based interventions to increase access to healthful foods and beverages. Because most food purchasing decisions are made in food stores, such settings are optimal for interventions aimed at influencing these decisions. The objective of this review was to synthesize the evidence on supermarket and grocery store interventions to promote healthful food choices. METHODS We searched PubMed through July 2012 to identify original research articles evaluating supermarket and grocery store interventions that promoted healthful food choices. We categorized each intervention by type of intervention strategy and extracted and summarized data on each intervention. We developed a scoring system for evaluating each intervention and assigned points for study design, effectiveness, reach, and availability of evidence. We averaged points for each intervention category and compared the strength of the evidence for each category. RESULTS We identified 58 articles and characterized 33 interventions. We found 7 strategies used alone or in combination. The most frequently used strategy was the combination of point-of-purchase and promotion and advertising (15 interventions); evidence for this category was scored as sufficient. On average, of 3 points possible, the intervention categories scored 2.6 for study design, 1.1 for effectiveness, 0.3 for reach, and 2 for availability of evidence. Three categories showed sufficient evidence; 4 showed insufficient evidence; none showed strong evidence. CONCLUSION More rigorous testing of interventions aimed at improving food and beverage choices in food stores, including their effect on diet and health outcomes, is needed.

Abstract
In developing recommendations for core measures/items for the evaluation of the Youth Expanded Food and Nutrition Education Program (EFNEP), three nutrition education curricula, implemented by land grant universities, were content analyzed. Selection criteria included the following: Curriculum content must include all EFNEP core content areas and must be implemented in more than one state with school children in third through fifth grades. Content analysis strategies were employed to identify and describe common areas/themes and mediators of behaviors addressed across the selected curricula. Content analysis coding was based on a list of behavioral mediators, which have empirical associations with nutrition, physical activity, and food safety. The most evident approaches identified across the three curricula were to enhance motivation, teach cognitive knowledge, and practice behavioral skills. The presence of self-regulation and environmental theory-based strategies was limited in all three curricula. In addition, multiple themes for nutrition, physical activity, and food safety were commonly addressed across curricula with multiple educational strategies. Based on these findings, recommendations for developing content appropriate measures and items for an outcome evaluation tool for Youth EFNEP are provided.

Abstract
BACKGROUND Measurement of social cognitive variables is often restricted to long-term and health-related outcomes. A more comprehensive measurement of cognitive determinants would enable evidence-based design of health behavior interventions with a focus on the most relevant targets. The purpose of this study was to examine the relative impact of different social cognitive determinants on fruit and vegetable (FV) and fast food consumption. METHODS Finnish male conscripts (N = 855, age M = 20) filled in questionnaires on social cognitive factors when entering the military service, and on food consumption frequency after two months. The data were analysed using structural equation modeling. RESULTS Physical well-being expectation and bad taste expectation were most strongly related to both FV and fat avoidance intentions. Perceived weight gain risk predicted fat avoidance intention, whereas perceived risk for other health problems predicted FV intention. Social self-efficacy was associated with FV intention only. Consumption of both FV and fast food was predicted by action planning and intention. CONCLUSIONS A more careful evaluation of subtypes of social cognitions sheds light on the specific content behind motivation. Such understanding might help in designing more effective intervention messages.

Abstract
BACKGROUND Dairy intake by college students is markedly lower than recommendations. Interventions to improve dairy intake based on Social Cognitive Theory (SCT) have potential to successfully change behavior by improving mediators that influence dietary choices. OBJECTIVE We aimed to use SCT to improve social support, self-efficacy, outcome expectations, self-regulation, and behavior related to dairy intake in college students. DESIGN We conducted a randomized nutrition education intervention. PARTICIPANTS/SETTING Participants included 211 college students (mean age 20.2 ± 0.1 years; 63% women and 37% men) recruited from a university campus. Participants in the intervention group (n=107) and comparison group (n=104) received an 8-week dairy intake or stress management intervention, respectively, via electronic mail. Data collection included dairy intake from 7-day food records and SCT variables from questionnaires administered during January 2008 and April 2008. MAIN OUTCOME MEASURES Changes in dairy intake and SCT variables (ie, social support, self-efficacy, outcome expectations, and self-regulation). STATISTICAL ANALYSES PERFORMED Multivariate analysis of covariance, with age and sex as covariates (P<0.05). RESULTS Ninety-one percent of participants (n=97 intervention, n=94 comparison) provided data; complete data were analyzed for 85% of participants (n=90 intervention, n=89 comparison). Participants in the intervention group reported higher intake of total dairy foods (P=0.012) and improved use of self-regulation strategies for consuming three servings per day of total dairy (P=0.000) and low-fat dairy foods (P=0.002) following the intervention. CONCLUSIONS Nutrition education via electronic mail based on an SCT model improved total dairy intake and self-regulation. Participants reported increased dairy intake and better use of self-regulation strategies. Future interventions should focus on benefits of consuming low-fat vs higher-fat dairy foods.

Abstract
The effectiveness of e-health interventions varies greatly. Despite this, there has been relatively little formal consideration of how differences in the design of an intervention (i.e., how the content is delivered) may explain why some interventions are more effective than others. This review primarily examines the use of the Internet to provide educational and self-management interventions to promote health. The article develops hypotheses about how the design of these interventions may be associated with outcomes. In total, 52 published reports from both a diversity sample and a representative sample were reviewed using techniques from Critical Interpretive Synthesis. Four core interactive design features were identified that may mediate the effects of intervention design on outcomes: Social context and support, contacts with intervention, tailoring, and self-management. A conceptual framework to summarize the design of e-health interventions delivered using the Internet is proposed. The framework provides a guide for systematic research to identify the effects of specific design features on intervention outcomes and to identify the mechanisms underlying any effects. To optimize the design of e-health interventions more work is needed to understand how and why these design features may affect intervention outcomes and to investigate the optimal implementation and dosage of each design feature.

Abstract
OBJECTIVE There has been a growing interest in tailored nutrition education over the previous decade, with a number of literature reviews suggesting this intervention strategy holds considerable potential. Nevertheless, the majority of intervention trials undertaken to date have employed subjective self-report outcome measures (such as dietary recalls). The aim of the present review is to further consider the likely true effect of tailored nutrition education by assessing the findings of tailored nutrition education intervention trials where objective outcome measures (such as sales data) have been employed. RESULTS Four trials of tailored nutrition education employing objective outcome measures were identified: one was undertaken in eight low-cost supermarkets in New Zealand (2010; n 1104); one was an online intervention trial in Australia (2006; n 497); and two were undertaken in US supermarkets (1997 and 2001; n 105 and 296, respectively). Findings from the high-quality New Zealand trial were negative. Findings from the US trials were also generally negative, although reporting was poor making it difficult to assess quality. Findings from the high-quality online trial were positive, although have limited generalisability for public health. CONCLUSIONS Trials employing objective outcome measures strongly suggest tailored nutrition education is not effective as a stand-alone strategy. However, further large, high-quality trials employing objective outcome measures are needed to determine the true effectiveness of this popular nutrition intervention strategy. Regardless, education plays an important role in generating social understanding and acceptance of broader interventions to improve nutrition.

Abstract
OBJECTIVE To evaluate the efficacy of computer-tailored nutrition education with objective outcome measures. DESIGN A 3-group randomized, controlled trial with posttests at 1 and 6 months post-intervention. SETTING Worksites and 2 neighborhoods in the urban area of Rotterdam. PARTICIPANTS A convenience sample of healthy Dutch adults (n = 442). INTERVENTIONS A computer-tailored intervention delivered on CD-ROM; a computer-tailored intervention delivered in print; and a generic information condition. MAIN OUTCOME MEASURES Blood lipids (total, high-density lipoprotein, and low-density lipoprotein cholesterol, and triacylglycerol) were measured by analyzing venous blood samples. ANALYSIS Linear mixed model procedure. RESULTS There were no significant differences among the 3 intervention groups in total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triacylglycerol. CONCLUSIONS AND IMPLICATIONS Contrary to results based on self-report data, no effects of the computer-tailored interventions were found based on objective outcomes. This contradiction calls for a critical reflection on the use of computer-tailored nutrition education interventions and the need to improve those interventions. Furthermore, this study indicates that feasible methods are needed to objectively assess the impact of computer-tailored nutrition education interventions in free-living subjects.

Abstract
Background The Internet is a trusted source of health information for growing majorities of Web users. The promise of online health interventions will be realized with the development of purely online theory-based programs for Web users that are evaluated for program effectiveness and the application of behavior change theory within the online environment. Little is known, however, about the demographic, behavioral, or psychosocial characteristics of Web-health users who represent potential participants in online health promotion research. Nor do we understand how Web users’ psychosocial characteristics relate to their health behavior—information essential to the development of effective, theory-based online behavior change interventions. Objective This study examines the demographic, behavioral, and psychosocial characteristics of Web-health users recruited for an online social cognitive theory (SCT)-based nutrition, physical activity, and weight gain prevention intervention, the Web-based Guide to Health (WB-GTH). Methods Directed to the WB-GTH site by advertisements through online social and professional networks and through print and online media, participants were screened, consented, and assessed with demographic, physical activity, psychosocial, and food frequency questionnaires online (taking a total of about 1.25 hours); they also kept a 7-day log of daily steps and minutes walked. Results From 4700 visits to the site, 963 Web users consented to enroll in the study: 83% (803) were female, participants’ mean age was 44.4 years (SD 11.03 years), 91% (873) were white, and 61% (589) were college graduates; participants’ median annual household income was approximately US $85,000. Participants’ daily step counts were in the low-active range (mean 6485.78, SD 2352.54) and overall dietary levels were poor (total fat g/day, mean 77.79, SD 41.96; percent kcal from fat, mean 36.51, SD 5.92; fiber g/day, mean 17.74, SD 7.35; and fruit and vegetable servings/day, mean 4.03, SD 2.33). The Web-health users had good self-efficacy and outcome expectations for health behavior change; however, they perceived little social support for making these changes and engaged in few self-regulatory behaviors. Consistent with SCT, theoretical models provided good fit to Web-users’ data (root mean square error of the approximation [RMSEA] < .05). Perceived social support and use of self-regulatory behaviors were strong predictors of physical activity and nutrition behavior. Web users’ self-efficacy was also a good predictor of healthier levels of physical activity and dietary fat but not of fiber, fruits, and vegetables. Social support and self-efficacy indirectly predicted behavior through self-regulation, and social support had indirect effects through self-efficacy. Conclusions Results suggest Web-health users visiting and ultimately participating in online health interventions may likely be middle-aged, well-educated, upper middle class women whose detrimental health behaviors put them at risk of obesity, heart disease, some cancers, and diabetes. The success of Internet physical activity and nutrition interventions may depend on the extent to which they lead users to develop self-efficacy for behavior change, but perhaps as important, the extent to which these interventions help them garner social-support for making changes. Success of these interventions may also depend on the extent to which they provide a platform for setting goals, planning, tracking, and providing feedback on targeted behaviors.
