[Ab] Resumo:BACKGROUND: An individual's perceived need to improve their physical health (PNIPH) is an essential precursor to adopting healthy behaviors. Nine potentially modifiable risk factors (PMRFs) for myocardial infarction collectively account for ≥90% of the population attributable risk. Though widely recognized, their impact on individuals' health perceptions is unclear. METHODS AND RESULTS: Residents from 6 provinces were administered a module on changes to improve health as part of the 2011-2012 Canadian Community Health Survey, yielding relevant data for 8 of the 9 PMRFs sought. The potential effects of PMRFs individually and cumulatively on PNIPH were examined using modified Poisson regression. In total, 45 443 respondents were included, representing 11 006 123 individuals and corresponding to 96.8% of the adult population of the sampled provinces. The sum of PMRFs was positively associated with PNIPH (adjusted prevalence ratio, 1.08; 95% CI, 1.07-1.09 per additional PMRF) with 82.3% of individuals with ≥5 PMRFs reporting this perception. Smoking, obesity, and low physical activity were most strongly associated with PNIPH, whereas hypertension and diabetes mellitus exhibited no association with this outcome after adjusting for potential confounders. Barriers to adopting healthy behaviors were reported by 55.9% of individuals endorsing PNIPH. CONCLUSIONS: The cumulative burden of PMRFs is positively associated with PNIPH; however, individual PMRFs differentially contribute to this perception. Among those at highest cardiac risk, ≈1 in 5 denied PNIPH. A better understanding of factors underlying health perceptions and behaviors is needed to capitalize on cardiovascular preventive efforts.

[Ti] Título:A Cash-back Rebate Program for Healthy Food Purchases in South Africa: Selection and Program Effects in Self-reported Diet Patterns.

[Ab] Resumo:OBJECTIVES: A South African insurer launched a rebate program for healthy food purchases for its members, but only available in program-designated supermarkets. To eliminate selection bias in program enrollment, we estimated the impact of subsidies in nudging the population towards a healthier diet using an instrumental variable approach. METHODS: Data came from a health behavior questionnaire administered among members in the health promotion program. Individual and supermarket addresses were geocoded and differential distances from home to program-designated supermarkets versus competing supermarkets were calculated. Bivariate probit and linear instrumental variable models were performed to control for likely unobserved selection biases, employing differential distances as a predictor of program enrollment. RESULTS: For regular fast-food, processed meat, and salty food consumption, approximately two-thirds of the difference between participants and nonparticipants was attributable to the intervention and one-third to selection effects. For fruit/ vegetable and fried food consumption, merely one-eighth of the difference was selection. The rebate reduced regular consumption of fast food by 15% and foods high in salt/sugar and fried foods by 22%- 26%, and increased fruit/vegetable consumption by 21% (0.66 serving/day). CONCLUSIONS: Large population interventions are an essential complement to laboratory experiments, but selection biases require explicit attention in evaluation studies conducted in naturalistic settings.

[Ab] Resumo:OBJECTIVES: We assessed the network of agencies in local communities that promote healthy eating and lifestyles among populations with limited resources. METHODS: Network surveys were administered among 159 Illinois agencies identified as serving limited-resource audiences categorized into 8 types: K-12 schools, early childhood centers, emergency food providers, health-related agencies, social resource centers, low-income/subsidized housing complexes, continuing education organizations, and others. Network analysis was conducted to examine 4 network structures - communications, funding, cooperation, and collaboration networks between agencies within each county/county cluster. RESULTS: Agencies in a network were found to be loosely connected, indicated by low network density. Reporting accuracy might be of concern, indicated by low reciprocity. Agencies in a network are decentralized rather than centralized around a few influential agencies, indicated by low betweenness centrality. There is suggestive evidence regarding homophily in a network, indicated by some significant correlations within agencies of the same type. Agencies connected in one network are significantly more likely to be connected in all the other networks as well. CONCLUSIONS: Promoting healthy eating and lifestyles among populations with limited resources warrants strong partnership across agencies in communities. Network analysis serves as a useful tool to evaluate community partnerships and facilitate coalition building..

[Ab] Resumo:OBJECTIVE: To investigate whether improving adherence to healthy dietary patterns interacts with the genetic predisposition to obesity in relation to long term changes in body mass index and body weight. DESIGN: Prospective cohort study. SETTING: Health professionals in the United States. PARTICIPANTS: 8828 women from the Nurses' Health Study and 5218 men from the Health Professionals Follow-up Study. EXPOSURE: Genetic predisposition score was calculated on the basis of 77 variants associated with body mass index. Dietary patterns were assessed by the Alternate Healthy Eating Index 2010 (AHEI-2010), Dietary Approach to Stop Hypertension (DASH), and Alternate Mediterranean Diet (AMED). MAIN OUTCOME MEASURES: Five repeated measurements of four year changes in body mass index and body weight over follow-up (1986 to 2006). RESULTS: During a 20 year follow-up, genetic association with change in body mass index was significantly attenuated with increasing adherence to the AHEI-2010 in the Nurses' Health Study (P=0.001 for interaction) and Health Professionals Follow-up Study (P=0.005 for interaction). In the combined cohorts, four year changes in body mass index per 10 risk allele increment were 0.07 (SE 0.02) among participants with decreased AHEI-2010 score and -0.01 (0.02) among those with increased AHEI-2010 score, corresponding to 0.16 (0.05) kg versus -0.02 (0.05) kg weight change every four years (P<0.001 for interaction). Viewed differently, changes in body mass index per 1 SD increment of AHEI-2010 score were -0.12 (0.01), -0.14 (0.01), and -0.18 (0.01) (weight change: -0.35 (0.03), -0.36 (0.04), and -0.50 (0.04) kg) among participants with low, intermediate, and high genetic risk, respectively. Similar interaction was also found for DASH but not for AMED. CONCLUSIONS: These data indicate that improving adherence to healthy dietary patterns could attenuate the genetic association with weight gain. Moreover, the beneficial effect of improved diet quality on weight management was particularly pronounced in people at high genetic risk for obesity.

[Ab] Resumo:OBJECTIVE: To evaluate the effectiveness of nudge activities at school on the students' body mass index (BMI). DESIGN: School-based factorial randomized community trial. SETTING: Eighteen public schools in the municipality of Duque de Caxias, metropolitan area of Rio de Janeiro, Brazil. PARTICIPANTS AND INTERVENTION: The 18 schools will be randomized into 4 group arms: group 1-control (without any activity); group 2-will receive educational activities in the classroom; group 3-will receive changes in the school environment (nudge strategies); group 4-will receive educational activities and changes in the school environment. Activities will occur during the 2018 school-year. MAIN OUTCOME MEASURE(S): The primary (BMI) and secondary (body fat percentage) outcomes will be assessed at baseline and after the study using a portable electronic scale with a segmental body composition monitor. The height will be measured by a portable stadiometer. ANALYSIS: Statistical analyses for each outcome will be conducted through linear mixed models that took into account the missing data and cluster effect of the schools.

[Ab] Resumo:Excess consumption of added dietary sugars is related to multiple metabolic problems and adverse health conditions. Identifying the modifiable social cognitive and motivational constructs that predict sugar consumption is important to inform behavioral interventions aimed at reducing sugar intake. We tested the efficacy of an integrated dual-process, dual-phase model derived from multiple theories to predict sugar consumption. Using a prospective design, university students (N = 90) completed initial measures of the reflective (autonomous and controlled motivation, intentions, attitudes, subjective norm, perceived behavioral control), impulsive (implicit attitudes), volitional (action and coping planning), and behavioral (past sugar consumption) components of the proposed model. Self-reported sugar consumption was measured two weeks later. A structural equation model revealed that intentions, implicit attitudes, and, indirectly, autonomous motivation to reduce sugar consumption had small, significant effects on sugar consumption. Attitudes, subjective norm, and, indirectly, autonomous motivation to reduce sugar consumption predicted intentions. There were no effects of the planning constructs. Model effects were independent of the effects of past sugar consumption. The model identified the relative contribution of reflective and impulsive components in predicting sugar consumption. Given the prominent role of the impulsive component, interventions that assist individuals in managing cues-to-action and behavioral monitoring are likely to be effective in regulating sugar consumption.

[Ab] Resumo:Hispanic families are at elevated risk for certain diet related illnesses including obesity and diabetes. Brighter Bites is a 16-week school-based program that delivers produce and nutrition education to high-need areas. The purpose of this study was to explore the adoption of Brighter Bites healthy eating strategies in low-income Spanish-speaking families as well as barriers to the sustainability of improved dietary behaviors using Photovoice. Two researchers worked with a predominately Hispanic, low-income public school to conduct the project. Spanish speaking parents participating in Brighter Bites were recruited and five mothers completed the study. Participants developed research questions, took documentary photos, attended group analysis sessions, and organized a community event. Photos from participants were gathered at two time points: i) during the Brighter Bites produce distributions, and ii) when the distributions were no longer in session. Participants organized resulting photos into themes during discussion groups that proceeded each photo-taking period. Themes that emerged during the produce distribution period included: cost savings, increased variety and accessibility of fresh produce, and ability to practice healthy eating. Themes that emerged when the weekly produce distributions were no longer in session included: increased costs, lack of variety, the continued effect of Brighter Bites, and innovative ways to cook with produce. Overall, participants were enthusiastic about the benefits they experienced with the program, but noted hardships in accessing nutritious food without the produce distributions in session. Innovative approaches are needed to create sustainable pathways to healthful food access after community nutrition interventions are complete.

[Ti] Título:When hunger does (or doesn't) increase unhealthy and healthy food consumption through food wanting: The distinctive role of impulsive approach tendencies toward healthy food.

[Ab] Resumo:OBJECTIVE: Hunger indirectly triggers unhealthy high-calorie food consumption through its positive effect on the incentive value (or "wanting") for food. Yet, not everyone consumes unhealthy food in excess, suggesting that some individuals react differently when they are exposed to unhealthy high-calorie food, even when they are hungry. The purpose of the present study was to investigate whether individual differences in impulsive approach tendencies toward food may explain how, and for whom, hunger will influence unhealthy food consumption through its effect on food wanting. A complementary goal was to explore whether these individual differences also influence healthy food consumption. METHODS: Students (N = 70) completed a questionnaire measuring their hunger and food wanting. Then, they performed a manikin task designed to evaluate their impulsive approach tendencies toward unhealthy food (IAUF) and healthy food (IAHF). The main outcomes variables were the amount of sweets (i.e., unhealthy food) and raisins (i.e., healthy food) consumed during a product-testing task. RESULTS: A moderated mediation analysis revealed that the indirect effect of hunger on unhealthy consumption through food wanting was moderated by IAHF. Specifically, hunger positively predicted sweets consumption through wanting for food among individuals with a low or moderate, but not high IAHF. The moderated mediation pattern was, however, not confirmed for IAUF. Finally, results revealed a direct and positive effect of IAHF on raisins consumption. CONCLUSION: These findings showed that IAHF play a protective role by preventing hunger to indirectly increase unhealthy food consumption through wanting for food. It confirms the importance of considering how individuals may differ in their impulsive approach tendencies toward food to better understand why some individuals will increase their unhealthy food intake when they are hungry, whereas other will not.

[Ab] Resumo:Descriptive social-normative messaging positively influences short-term dietary choices and healthy food intake. The purpose of this study was to evaluate the effects of descriptive normative messages on college students' skin carotenoid concentrations (a biomarker of carotenoid-containing fruit and vegetable [FV] intake) over an 8-week period. 251 college students consented to participate and 74% completed the study. Students were randomly assigned to groups who, following a baseline evaluation of skin-carotenoid levels, were told how their score ranked within a peer group of college students attending the same university (Individualized Normative group), that their score was in the lower 20th percentile of the peer group (Manipulated Normative group), or were given no information about their score or the peer group (Control group). Skin carotenoid concentrations were reassessed 8 weeks after the normative messages were presented or withheld. Skin carotenoid levels of those in the Manipulated Normative group increased significantly more than did scores of those in the Control group (t (126) = 3.74, p < 0.001; d = 0.67), but these students' self-reported FV intake did not increase. This finding suggests normative messaging can influence behavior for up to 8 weeks, but future research must better evaluate if the increase in skin carotenoids reflects increased FV consumption, increased consumption of carotenoid-containing FV (with decreased consumption of other FV), or is accounted for by some other behavior change (e.g., increased use of supplements). These findings support further exploration of normative messaging as a technique for producing the long-term behavior change needed to impact public health.
