RESUMO

Periconceptional maternal ultra-processed food (UPF) consumption impairs embryonic growth. Impacts of exposure to UPF on distinct components of fetal growth in late pregnancy are unknown. We investigated the influence of frequency of UPF consumption during pregnancy on fetal head circumference (HC), abdominal circumference (AC) and femur length (FL). This study included 417 live-born singleton pregnancies prospectively followed-up since the antenatal period in the MINA-Brazil Study, with an available ultrasound scan at >24 gestational weeks. Frequency of food groups consumption in the previous month was categorised as no/monthly, weekly or daily. Ultrasound scans were conducted at 27·8 (sd: 1·7) gestational weeks. HC, AC and FL z-scores were calculated for gestational age using the INTERGROWTH-21st Project standards. Simultaneous-quantile regression models were fitted at the 10th, 50th and 90th percentiles of the distribution of each ultrasound parameter according to UPF consumption, with adjustment for potential confounders. Participants were aged on average 24·7 (sd: 6·5) years, 44·8 % were primiparous, and 26·9 % and 24·9 %, respectively, had weekly and daily UPF consumption. Compared with no/monthly intake, daily UPF consumption impaired HC across its distribution, with significant effect sizes varying from -0·24 to -0·40 z-score. Weekly UPF consumption decreased HC at the 90th percentile by -0·39 z-score (95 % CI: -0·78, -0·01) and FL at the 50th percentile by -0·32 z-score (95 % CI: -0·60, -0·04). No association was noted with AC. Frequency of UPF consumption was negatively associated with skeletal components of fetal growth in late pregnancy. Infant body composition may benefit from healthy food practices since pregnancy.

RESUMO

We examined whether weight loss following HAES®-based interventions associates with changes in cardiometabolic risk factors and quality of life of women with obesity. This was an exploratory, ancillary analysis of a 7-month, mixed-method, randomized controlled trial. Fifty-five women (age: 33.0 ± 7.2; BMI: 30-39.9 kg/m2) were included in this study. Body weight, cardiovascular risk factors, clustered cardiometabolic risk, and quality of life were assessed before (Pre) and after HAES®-based interventions (Post). Delta scores (Post-Pre) were calculated for each outcome and used in linear regression models. After adjusting by potential confounders, weight loss was associated with improvements in waist circumference (ß = 0.83, p <0.001), fasting glycemia (ß = 0.45, p = 0.036), total cholesterol (ß = 1.48, p = 0.024), LDL (ß = 1.33, p = 0.012), clustered cardiometabolic risk (ß = 0.18, p = 0.006), and quality of life (ß = -1.05, p = 0.007). All participants but one who reduced body weight (n = 11) improved clustered cardiometabolic risk and quality of life. Of relevance, 34% and 73% of the participants who maintained or gained weight improved clustered cardiometabolic risk and quality of life, respectively, although the magnitude of improvements was lower than that among those who lose weight. Improvements in cardiovascular risk factors and quality of life following HAES®-based interventions associated with weight loss as expected. However, most of the participants who maintained or even gained weight experienced benefits to some extent. This suggests that weight-neutral, lifestyle-modification interventions may improve wellness and health-related outcomes, even in the absence of weight loss.

RESUMO

OBJECTIVE: To assess how mothers classify foods and how their eating practices interact with these classifications, with special attention to meanings and uses given to ultra-processed foods. DESIGN: Qualitative research with in-depth interviews and pile sorts. SETTING: Urban Brazilian Amazon. PARTICIPANTS: A sample of 34 mothers were selected through theoretical sampling. ANALYSIS: Content analysis for in-depth interviews and multidimensional scaling and cluster analysis for pile sorts. PHENOMENON OF INTEREST: Food classification. RESULTS: Classifications were based on context (ie, a time or a situation in which the food is eaten) and foods' healthiness. Five food groupings based on mothers' classifications were defined: (1) main meal foods, (2) fruits and fruit juices, (3) convenient foods, (4) leisure foods, and (5) canned sardines. Ultra-processed foods were classified differently from non-ultra-processed foods and considered unhealthy, consumed on special occasions or when there was no time or desire to cook. CONCLUSIONS AND IMPLICATIONS: Results highlight the potential of incorporating context-based categories and personal experiences to guide nutrition interventions and the potential of pile sorts to tailor messages to target populations.

RESUMO

BACKGROUND: Dietary Guidelines are an important tool for population health promotion efforts. However, current surveillance data suggest that only a small minority of the population meet the 2014 Brazilian Dietary Guidelines (BDG) recommendations. Translating recommendations into practice may not be immediately clear and behavior-change messages guiding the behaviors that need to be changed and identifying substitute practices to meet a specific recommendation, are required. This study details the methods undertaken to develop and refine messages supporting the adoption of healthy dietary choices and behaviors in adults, as outlined in the BDG. METHODS: A sequential, five-step, mixed-methods approach, determined a priori, was followed for designing and refining messages. These included: (1) content extraction; (2) audience analysis; (3) input from an expert review panel; (4) message development and message refinement; and a (5) test of content validity. RESULTS: The content extraction process led to the identification of 63 excerpts from the BDG, organized into themes. The audience analysis highlighted barriers to healthy eating that included lack of time (to eat, to cook), difficulty in accessing healthy food, the convenience and the ubiquitous marketing of ultra-processed foods. Twenty of the 63 DG excerpts reviewed by the expert panel were identified as being a priority for message development and total of 111 messages were developed. Messages were short, structured to be one-sided, conveyed the most important information at the beginning (anticlimactic), used simple language and were explicit in the information they relayed. They were positive and gain-framed and used an empathetic, solution- or substitution-based tone and were presented in the active voice. The messages focused on goals and skill development, behavior regulation, incentivized positive practices as time and/or cost saving. Content validity testing helped further messages and reduced the number of messages from 111 to 40. CONCLUSIONS: This study provides the blue-print for the phase-wise development of messages that synthesize the key recommendations of the food-based BDG and communicate the adoption of behaviors and goals that are consistent with it's message. It details methods which could be adapted and replicated for message development in other contexts.

RESUMO

This article describes and explore eating practices and food preferences among gay men who call themselves bears in São Paulo, Brazil, and their relation with their life history, masculinities representations, and sexuality. It is a qualitative and quantitative research within an ethnographic perspective. A purposive sample of thirty-five self-declared gay bears. The data were analyzed identifying the regular, expressive and meaningful significance units collected through the interviews. We identified that the self-declared bears in São Paulo, Brazil, build a solid relation between food preferences, eating practices, masculinity, and group belonging. From the bear's perspective, meat, especially bovine, is related to masculinity and extensively understood as a strong common bond within the community, leveraging their sexuality. For these persons, eating meat as well as drinking beer can build the ideal mannish and unfeminine body that is overvalue. Being gay and "eating like a man," as well as exposing a "macho" body while disdaining other body types constructions could represent a strategy to avoid discrimination, shame and humiliation. On the other way, this community does not just linearly imitate heterosexual men although their conducts can reproduce patriarchal representations and meanings through eating practices. These findings could be used to understand the complexity of alimentary practices, particularly food preferences as well as commensalities, among specific communities or membership groups.

RESUMO

This study aimed to assess consumers' uses of and opinions on the current Brazilian food label and their reaction to the introduction of a front-of-package warning label. We conducted 12 focus groups among a diverse sample of adult consumers, to broadly assess: (1) uses of and perceptions about the current food label, and (2) opinions about implementing a front-of-package warning label to guide food purchases. Data was analyzed with a triangulation of researchers using an exploratory content analysis, which allowed codes to emerge from the data. The frequency of codes across focus groups was compared by gender and socioeconomic status to explore differences by these sociodemographic factors. Codes were divided into six main themes: (1) "Reasons for using food labels"; (2) "Barriers to using food labels"; (3) "Requirements for a new label"; (4) "Perceived influence on consumption behaviors"; (5) "Perceived influence on child behaviors"; and (6) "Perceptions of the food manufacturers using of warning labels". Participants used food labels to check nutrient content and ingredient information but the format of these labels and the technicality of the content displayed often made the information inaccessible, particularly for those with low socioeconomic status. Most participants were supportive of the display of front-of-package warning labels on products and considered them useful to inform purchases. Women believed that they and their children would reduce the consumption of foods with front-of-package warning labels, while men reported more polarity in their intentions. For men and their children, front-of-package warning labels would result in either stopping food intake entirely or continued consumption without changes to the amount. The study results highlight the potential of front-of-package warning labels to support healthier behaviors in both consumers and their children.

RESUMO

INTRODUCTION: Warning labels (WLs) are the newest paradigm of nutrient-based, front-of-package labels (FOP) that have been consistently shown to be more effective at informing consumer purchases than other FOP labels. Their effectiveness may be attributed to their design and the consistency in the information they communicate. The present study assessed designs effects of WLs in improving understanding and perceptions among 2419 Brazilian adults. METHODS: Participants were randomly assigned to one of four study arms in an online, randomized, controlled experiment: (1) the Triangular WL 'A lot of /Muito' (Muito); (2) Triangular WL 'High in/Alto em' (Alto); (3) the Chilean WL 'High in/Alto em' (Chile); and (4) a control condition (no WL). Participants responded to a series of questions, while viewing images of 9 products, that assessed their understanding of the nutrient content of the product, its healthfulness, and their intentions to purchase. All aggregate differences in responses between study arms were estimated using oneway-ANOVAs. RESULTS: WLs were superior to the list of ingredients and the nutrition facts panel in improving participant understanding and perceptions of the nutrient profile of products, particularly in helping identify nutrients in excess. Alto was significantly better than the control at identifying which of the two products contained an excess of nutrients and at improving consumer understanding of nutrient content across different indicators. Alto, followed by Muito, was also better at communicating that fewer WLs signified a healthier product. The Muito WL was significantly more visible to participants than the Chile WL. There were no differences between study arms in shifting consumer purchase intentions. CONCLUSIONS: In this study, WLs were an important addition to the current nutrition label. The triangular symbol, the white background and the signal word, 'High in/ Alto em' showed consistently better results than the signal word 'A lot of/ Muito' and the octagonal symbol. These design elements serve to make WLs more visible to consumers, capturing their attention and informing their food evaluations, and may have greater potential to influence appropriate for a Brazilian audience.

RESUMO

INTRODUCTION: Health at Every Size (HAES) is a weight-neutral approach focused on promoting healthy behaviors in people with different body sizes and on enhancing pleasure derived from consuming food to achieve sustainable healthy eating outcomes. However, to the best of our knowledge, there are no studies in the literature assessing the effects of the HAES approach on perceptions of eating pleasure. OBJECTIVE: We qualitatively investigated the perceptions of obese women about eating pleasure before and after a new interdisciplinary, nonprescriptive intervention based on the HAES approach. DESIGN: The intervention was a randomized controlled clinical trial, designated as Health and Wellness in Obesity, conducted over 7 months at University of São Paulo (Brazil). We used a qualitative approach to data construction and analysis of perceptions about eating pleasure. Participants were randomized to either the intervention (I-HAES) group or the control (CTRL) group. The I-HAES group featured individual nutritional counseling, group practice of enjoyable physical activity, and philosophical workshops. The CTRL group was a traditional HAES intervention group (lecture-based model). Focus group discussions eliciting perceptions of pleasure around eating were conducted at baseline and post-study. Focus group transcripts were analyzed by exploratory content analysis. PARTICIPANTS: Forty-three women aged 25 to 50 years with body mass index (measured in kilograms per square meter) between 30 and 39. 9 completed the intervention and the focus groups, with 32 in the I-HAES group and 11 in the CTRL group. RESULTS: Lack of guilt about experiencing pleasure while eating and increased reflection on their own desires increased in participants of both groups after the study. The I-HAES group also displayed a greater sense of autonomy related to eating, increased pleasure in commensality, familiarity with the practice of cooking, and decreased automatic eating. CONCLUSION: HAES-based intervention featuring nutritional counseling, appreciation for physical activity, and philosophical engagement was shown to stimulate pleasure around eating without leading to indiscriminate eating.

RESUMO

The aim of this study is to have an exploratory insight on how a sample of Brazilian adults classify food, attempting to identify the main factors involved in this process, and to compare these classifications to the NOVA food classification of the 2014 Brazilian dietary guidelines. An exploratory and qualitative approach was conducted with a selected sample of teachers, administrative technicians, and students (N = 24) from the Federal University of Grande Dourados, Brazil. First, using the pile sort method, participants were asked to freely classify 24 pictures of food (sourced from examples of the four food groups specified in NOVA) into food groups meaningful to them. Next, in semi-structured interviews, participants were asked to describe the food groups they created. The food groups created by participants were analyzed using non-metric multidimensional scaling followed by hierarchical cluster analysis, and the interviews were analyzed using content analysis. Participants had a mean age of 30 (±9.4) years. A total of 128 food groups were created by 24 participants (an average of five food groups per person); and a total of 55 non-mutually exclusive groups names were used by them to describe these food groups. Sixteen themes emerged from the content analysis. The most recurrent themes were food groups, nutrients, foods I consume, foods I do not consume, and food processing. Contrasting themes such as real food and junk foods, meals and ready-made foods, healthy foods and unhealthy foods were also noted. Six clusters emerged from the cluster analysis, each related to one or more themes. Overall, a striking similarity was observed between the ways the individuals classified food and the NOVA food classification.
