Association of body image perception and (dis)satisfaction with adiposity in adults: The Pró-Saúde study.

INTRODUCTION: Body image distortion and/or dissatisfaction may occur primarily due to body fat accumulation and/or distribution. The aim of this study was to evaluate the frequency of body image perception and (dis)satisfaction categories in adult men and women according to the adiposity classification. METHODS: This is a cross-sectional study (n = 514; 33-79 years; 265 women) that is part of a prospective cohort (Pró-Saúde study). Adiposity measurements were determined by two methods: anthropometry, used to calculate the body mass index (BMI) and dual-energy X-ray absorptiometry (DXA), to estimate body fat percentage. Participants were grouped as "no excess adiposity" and "excess adiposity", considering BMI and body fat percentage (>30% for men, >40% for women). Perception and (dis)satisfaction with body image were evaluated using the Kakeshita scale, composed by 15 silhouettes, developed for the Brazilian population. Degree of distortion (perceived BMI - real BMI) and dissatisfaction (perceived BMI - desired BMI) were calculated. RESULTS: A high proportion of men (58.6%; 74.3%), and especially of women (82.6%; 86.8%), presented body size overestimation and dissatisfaction due to excess weight, respectively. A relevant fraction of the women (32.6%) and men (30.8%) who were dissatisfied due to excess weight did not present excess adiposity, especially if classified by DXA. Variability in degree of distortion was hardly explained by anthropometric and DXA variables in women (<5%) and men (∼22%). Both anthropometric and DXA measurements accounted for ∼30% and ∼50% of the variability in degree of dissatisfaction among women and men, respectively. CONCLUSION: Our results suggest a high frequency of body image distortion in Brazilian adult individuals, as well as dissatisfaction with excess weight, especially among women with excess adiposity. The findings indicate that anthropometric measurements explain much of the variability in degree of body image dissatisfaction in men, with no apparent advantage of the use of more refined DXA measurements.

Ultra-Processed Foods Elicit Higher Approach Motivation Than Unprocessed and Minimally Processed Foods.

Background: Ultra-processed foods (UPF) are becoming extensively available in the food environments. UPF are industrial formulations that are designed to maximize palatability and consumption through a combination of calorie-dense ingredients and chemical additives. UPFs are also aggressively marketed, which may make them more attractive than unprocessed/minimally processed foods (UMPF). Since consumers' purchase decisions are guided by food-evoked emotions, we aimed to provide evidence that UPF visual cues trigger higher emotional responses and approach motivation than UMPF visual cues, with potential impacts on individuals' intention to consume the UPF over the UMPF. Methods: Participants (n = 174; 144 women; mean age = 20.7 years; standard deviation = 4.35) performed two tasks. In the first task, 16 pictures of foods (8 UPF and 8 UMPF), and 74 pictures from other affective categories, were presented. After viewing each picture, the participants rated it along two basic dimensions of emotion through the Self-Assessment Manikin scale: pleasantness and arousal. In the second task, the participants viewed the same food pictures, and they rated their intention to consume the foods depicted in the pictures. Each picture was plotted in terms of its mean pleasantness and arousal ratings in a Cartesian plane, which resulted in an affective space. Results: Pictures of UPF and UMPF were positioned in the upper arm of the boomerang-shaped affective space that represents approach motivation. Pictures containing UPF triggered higher approach motivation and intention to consume than pictures containing UMPF. We also found a stronger association between emotional responses and intention to consume UPF relative to UMPF. Conclusion: These results shed new light on the role of ultra-processed foods evoked emotions that contribute to less healthy and sustainable food environments.

Weight Gain and Change in Body Mass Index after Age 20 in the Brazilian Population and Associated Sociodemographic Factors: Data from the National Health Survey.

Obesity is considered one of the main contemporary public health problems. We aim to assess changes in body weight and nutritional status in adulthood and the associated sociodemographic variables. We use data from the 2013 National Health Survey (n = 21,743). Changes in weight and body mass index (BMI) were calculated based on mean difference between measurements at age 20 and data collected at the interview, stratified by sex. The association was analyzed using linear regression. Mean weight gain was greater among women than men. The largest gain was verified among the younger adults for both sexes. Age was found to be associated with weight and BMI change in men and women where, for every additional year of age, there was an increase in weight and BMI of 0.10 kg and 0.04 kg/m2 in men and of 0.22 kg and 0.09 kg/m2 in women, respectively. For education, a direct association was found for men and an inverse for women. Association with area of residence was significant among males only, where rural men gained less than their urban counterparts. Weight gain was progressive, being more marked in the younger group, and was associated with education differently according to sex.

Assessment of trends of nutritional status, central obesity, and growth profile using anthropometric measurements in adolescent athletes from a sport-oriented public school.

BACKGROUND: The aims were to evaluate the nutritional status, central adiposity, and physical growth profile of adolescents in a sports-oriented public school (SOPS) and to describe the results considering the Brazilian and American adolescents' survey studies. METHODS: This study was a dynamic cohort, performed in 2012-2013 and 2015. 1,082 adolescent athletes (11-16 years old) participated. Anthropometric data (height [H], weight, and waist circumference [WC]) were collected yearly. The nutritional status was assessed using BMI Z-score; trunk fat, using WC and WC/H ratio; and growth, using height z-score. The SOPS results were described considering data from the Brazilian Household Budget Survey (HBS-Southeast region) and the National Health and Nutrition Examination Survey (NHANES). Anthropometric data was compared using linear mixed effects regression models, considering sex, age group and time. RESULTS: Considering height Z-score and BMI Z-score values, none of the adolescents in the SOPS had short stature or underweight, and the obesity prevalence was approximately 1% throughout the study. HBS survey revealed 3.4% of obesity prevalence in adolescents (11-16 years old). Considering age and time, significant differences in WC for both sexes were observed. However, considering NHANES data, our participants were classified in P5-25. CONCLUSIONS: These results suggest that the nutritional status of adolescents in the SOPS was good, obesity prevalence was 1% and WC measurement was within P5-25 considering NHANES data. This supports the public policies encouraging involvement in sports at school, which should be one of the priorities in the health promotion agenda, reducing the development of future chronic diseases.

Medicine expenses and obesity in Brazil: an analysis based on the household budget survey.

BACKGROUND: Obesity can be considered a global public health problem that affects virtually all countries worldwide and results in greater use of healthcare services and higher healthcare costs. We aimed to describe average monthly household medicine expenses according to source of funding, public or private, and to estimate the influence of the presence of obese residents in households on total medicine expenses. METHODS: This study was based on data from the 2008-2009 Brazilian Household Budget Survey, with a representative population sample of 55,970 households as study units. Information on nutritional status and medicines acquired and their cost in the past 30 days were analyzed. A two-part model was employed to assess the influence of obesity on medicine expenses, with monthly household medicine expenses per capita as outcome, presence of obese in the household as explanatory variable, and adjustment for confounding variables. RESULTS: Out-of-pocket expenses on medicines were always higher than the cost of medicines obtained through the public sector, and 32 % of households had at least one obese as resident. Monthly household expenses on medicines per capita in households with obese was US$ 20.40, 16 % higher than in households with no obese. An adjusted model confirmed that the presence of obese in the households increased medicine expenses. CONCLUSION: Obesity is associated with additional medicine expenses, increasing the negative impact on household budgets and public expenditure.

Food and beverage industries' participation in health scientific events: considerations on conflicts of interest / Participación de las industrias de la alimentación y las bebidas en acontecimientos científicos sobre temas de salud: consideraciones sobre conflictos de intereses

Several sectors of the industry (pharmaceutical, food, and other) often occupy a prominent position in scientific meetings on health. The aim of this article is to discuss the participation of food and beverage industries (Big Food and Big Soda) in events organized by scientific institutions in health and nutrition, highlighting potential conflicts of interest in such partnerships. As an example, the authors report the case of a Brazilian national event organized by a nutrition scientific association in 2011. Focused on the theme "Evidence-based Nutrition," the event's scientific program was largely influenced by corporate sponsors. For example, a symposium at this congress was organized by a beverage company known worldwide for its sugar-sweetened products and classified as the "diamond sponsor" of the event. While debating the adoption of healthy lifestyles in the current scenario of rising occurrence of obesity, the rationale for health promotion was reduced to providing information that would motivate rational individual choices, thus ignoring any political, economic, cultural, marketing, and social factors involved in the global process of nutrition transition. The authors conclude that conflicts of interest are present in the participation of food and beverage industries in health scientific events. The industries' strategy attempts to grant legitimacy to the production and marketing of their products through an association with adequate health practices. Health professionals and policy-makers should reflect on such partnerships because their main purpose is to generate profit, not the promotion of public health.

Diversos sectores de la industria (farmacéutico, alimentario y otros) a menudo ocupan una posición prominente en las reuniones científicas sobre temas de salud. El objetivo de este artículo es tratar sobre la participación de las industrias de la alimentación y las bebidas (Big Food and Big Soda) en acontecimientos organizados por instituciones científicas del ámbito de la salud y la nutrición, señalando los potenciales conflictos de intereses que surgen de tales asociaciones. Como ejemplo, los autores comentan sobre el acontecimiento nacional organizado el año 2011 en el Brasil por una asociación científica del ámbito de la nutrición. El programa científico de este acontecimiento, dedicado al tema de "La nutrición basada en datos probatorios", se vio influido en gran parte por sus patrocinadores corporativos. Por ejemplo, un simposio de este congreso fue organizado por una empresa productora de bebidas, conocida a escala mundial por sus productos azucarados y clasificada como "patrocinador diamante" del acontecimiento. Mientras se debatía sobre la adopción de modos de vida saludables en el contexto actual de incremento de los casos de obesidad, el ámbito de promoción de la salud se redujo a suministrar información que incitara a elecciones individuales racionales, sin que se tuvieran en cuenta los factores políticos, económicos, culturales, mercadotécnicos y sociales que el proceso mundial de transición nutricional involucra. Los autores concluyen que los conflictos de intereses existen en la participación de las industrias de la alimentación y las bebidas en acontecimientos científicos sobre temas de salud. La estrategia de las industrias intenta dar legitimidad a la producción y comercialización de sus productos mediante una asociación con prácticas de salud adecuadas. Los profesionales de la salud y las instancias normativas deben reflexionar sobre tales asociaciones, ya que su principal finalidad no es la promoción de la salud pública sino la generación de beneficios.
