RESUMO

BACKGROUND: Recent research has highlighted the relevance of a gut-health promoting diet as a possible treatment and prevention for depression. A dietary pattern with consumption of fermented food and high consumption of dietary fiber can promote gut health, physical health, and might even improve mental health. This study aimed to investigate the interrelationship among diet, physical health, and depression. METHODS: This study used a nationally representative sample (N = 16,572) from the National Health and Nutrition Examination Survey (2011-2018). Dietary information was collected by dietary recall interviews. Depression was assessed by the 9-item Patient Health Questionnaire. Subjective physical health was indicated by self-reported Body Mass Index (BMI). Objective physical health was indicated by BMI measured by trained health technicians. Path analysis was used to test the association between diet and depression, and the mediating roles of self-reported BMI and BMI measured by technicians. RESULTS: Consumption of probiotic foods and higher intake of fiber were significantly associated with lower levels of depressive symptoms. Both subjective and objective physical health significantly mediated the relationship between variables of diet and mild depressive symptoms. Subjective physical health also significantly mediated the relationship between high intake of dietary fiber and lower likelihood of reporting severe depressive symptoms. CONCLUSION: Despite being cross-sectional in nature, this study presented evidence that gut-health promoting diets may reduce depressive symptoms through improving physical health. These findings provide preliminary support to diet programs for preventing depression and diet programs as an alternative or supplementary treatment of depression.

RESUMO

Intermittent fasting (IF) is an increasingly popular diet involving short-term fasting and/or caloric restriction. While published research highlights physiological effects (e.g., weight, body fat) of IF, hardly any research has examined its associations with psychological factors. This study aimed to investigate the relationship between IF and binge eating, impulsivity, intuitive eating, and mindful eating. An undergraduate sample (N = 298) was recruited through a large southwestern university psychology subject pool. The sample was divided into three groups based on IF status: Current IF (n = 70), Past IF (n = 48), and No IF (n = 182). Current IF was negatively associated with lack of perseverance (e.g., "I generally like to see things through to the end"; p < .01) and intuitive eating (p < .05), varying by subscale, compared to the other groups. Notably, Past-IF, but not Current IF, participants were more likely to binge eat than individuals who reported never fasting (p = .03). These findings add credence to the rapidly developing area of research suggesting IF is associated with increased disordered eating behaviors. Notably, the findings from this study are limited due to the lack of diversity sample, such that generalizations can only be made toward White, middle-to-high income, college students. Future longitudinal studies are needed to test the directionality of these relationships.

RESUMO

Adolescents show one of the highest rates of ultra-processed foods and drinks (UPF) consumption, and studies indicate an association between their consumption and internalizing problems. We aim to investigate whether UPF consumption associates with dysfunctions in other psychosocial domains, as well as sex effects. In 560 Spanish adolescents (14-17 years old), we assessed the UPF products consumed in the previous day, fruits and vegetables consumption (servings/day), and physical activity (days/week). Psychosocial functioning (total and subscales) was assessed through the Pediatric Symptom Checklist-Youth self-report. Associations between UPF and psychosocial functioning were assessed using linear regression models, adjusting for sex, age, fruits and vegetables consumption, and physical activity. Sex-specific associations were also explored. Participants reported a daily consumption of 7.72 UPF servings per day, with male adolescents showing higher consumption than female adolescents. Consumption of fruits and vegetables and physical activity levels were lower than recommended. Psychosocial impairment was present in 26.2% of the participants. Higher UPF consumption was associated with higher presence of depressive symptoms and internalizing and externalizing problems in the whole sample and in male adolescents. The present study supports previous studies suggesting that UPF consumption may interact with mental health problems and indicates that these effects may go beyond internalizing problems.

RESUMO

Little is known regarding intuitive eating (IE), diet quality and adherence. We investigated the associations between IE, diet quality and metabolic health after gestational diabetes (GDM), who have an increased diabetes risk. Data from 179 women with GDM from MySweetheart trial (NCT02872974) were analyzed. IE was assessed using the eating for physical rather than emotional reasons (EPR) and reliance on hunger and satiety cues (RHSC) subscales of the French Intuitive Eating Scale-2. Metabolic outcomes included weight, central body fat and insulin resistance. Diet quality was calculated using the Alternative Health Eating Index (AHEI) and compliance with national recommendations was evaluated. Both IE subscales were associated with lower BMI and fat mass (BIA) at 1-year postpartum (all p ≤ 0.034). The EPR subscale inversely correlated with fat mass (DXA) and visceral adipose tissue (both p ≤ 0.028), whereas RHSC with higher insulin sensitivity (Matsuda, p = 0.034). RHSC during pregnancy predicted increased AHEI (p = 0.043) at 1-year postpartum, whilst EPR predicted lower fat mass and insulin resistance (HOMA-IR) (all p ≤ 0.04). In longitudinal analyses, both subscales were associated with increased adherence to dairy and fiber intake recommendations (both p ≤ 0.023). These data suggest IE may be an interesting approach to improve diet quality and metabolic outcomes in women with GDM.

RESUMO

BACKGROUND AND AIMS: One of the most pressing issues in the field of cardiometabolic disease is the growing co-occurrence of poor mental health. A whole foods-based, hypothesis-driven dietary inflammation score (DIS) was created to better understand the association between dietary patterns, inflammation, and physiological health. However, this diet quality scoring method has not been observed in young adults, nor has its association with mental health been observed. This study 1) examined differences in cardiometabolic health measures by dietary inflammation score (DIS) tertiles and 2) examined the association between DIS and psychosocial stress variables, perceived stress, and depression. METHODS: Psychosocial and food frequency questionnaires, demographics, anthropometrics, and clinical measures were collected from sixty-two metabolically healthy African American and European American females, ages 18-45, from 2014 to 2016 in Birmingham, AL. Analysis of Variance was used to observe differences in all cardiometabolic variables by DIS tertile. Linear regression was used to observe the relationship between independent, continuous variable DIS and dependent variables, depression, and perceived stress. RESULTS: There were significant differences between DIS tertiles for cardiometabolic and psychosocial stress measures. DIS was significantly positively associated with depression after controlling for body fat percentage (P = 0.003) and education, income, and race (P = 0.01). DIS was significantly associated with perceived stress after controlling for body fat percentage (P = 0.0004), and education, income, and race (P = 0.0005). CONCLUSION: This study is significant for its contribution in understanding how cardiometabolic health differs by DIS tertile, and how dietary inflammation scores are associated with depression and perceived stress among young adult women.

RESUMO

Non-dieting approaches, including mindful/intuitive eating, to health improvement are of increasing interest, yet little is known about young adults' social media exposure to them. Therefore, this study aimed to describe the imagery related to mindful/intuitive eating which is visible to young adult Instagram users. Images categorized under the hashtags 'mindfuleating' and 'intuitiveeating' were searched in September 2021 using the 'top posts' view. Screen captures of 1200 grid-view images per hashtag were used to construct coding frameworks and to determine saturation. Sample sizes for #mindfuleating and #intuitiveeating were 405 and 495 images, respectively. Individual images were coded collaboratively. Almost half of each sample depicted food or drink, of which 50-60% were healthy foods. Approximately 17% were single-person images, of which the majority were young, female adults with healthy weight. Approximately one-third of text suggested credibility through credentials, profession, or evidence. Messaging was similar for both hashtags, encompassing mindful/intuitive eating (~40%), nutrition/eating behaviours (~15%), physical/mental health (~20%), disordered eating (~12%), and body-/self-acceptance (~12%). Differences were observed between hashtags for weight-related concepts (20%/1%) and anti-diet/weight-neutral approaches (10%/35%). The representation on Instagram of mindful and intuitive eating portrays healthy lifestyles without a focus on weight but lacks demographical and body-type diversity. Instagram holds the potential for health professionals to disseminate culturally/demographically inclusive, evidence-based health/nutrition information to youth.

RESUMO

BACKGROUND: Diet is considered as one of the modifiable factors that appears to exert a vital role in psychological status. In this way, we designed this study to examine the association between dietary inflammatory index (DII), dietary antioxidant index (DAI), and mental health in female adolescents. METHODS: This cross-sectional study included 364 female adolescents selected from high schools in the five regions of Tabriz, Iran. A 3-day food record was used to extract the dietary data and calculate DII/DAI scores. DII and DAI were estimated to assess the odds of depression, anxiety, and stress based on the Depression Anxiety Stress Scales-21. Adjusted relationships of the DII and DAI with depression, anxiety, and stress were determined using multiple regression after adjusting for age, energy intake, BMI, family income and mother and father education. Overweight was defined as body mass index (BMI)-for-age > + 1 z-score relative to world health organization standards. RESULTS: Depression, anxiety, and stress were observed in 21.4%, 26.6%, and 25.7% of subjects, respectively. The percentage of overweight among adolescents was 19.4%. The association between DII and score of mental health profile was positive among subjects in the third tertile of DII compared to subjects in the first tertile. However, this association was not statistically significant after adjusting for confounding variables. Moreover, there was a significant inverse association between DAI and depression and anxiety; and a statistically insignificant association between DAI and stress after adjusting for confounders. CONCLUSIONS: Our results highlighted the importance of a healthy and anti-inflammatory diet on mental health in female adolescents. Therefore, modifying unhealthy dietary habits are likely to be effective in the management of psychosocial disorders.

RESUMO

The dietary transition from traditional to commercial foods and a decrease in physical activity (PA) have impacted the health of the First Nations people of Quebec (Canada), resulting in many suffering from multiple chronic diseases. This study had two objectives: (1) to examine eating and PA behaviors among First Nations peoples in urban areas and (2) to explore the associated health representations. To achieve these objectives, a mixed-methods approach, including a questionnaire (n = 32) and a semi-structured interview (n = 14), was used to explore the participants' lifestyle profiles and health experiences. The questionnaire focused on the eating and PA behaviors of First Nations people and their underlying motivations. At the same time, the interviews investigated their health views on diet and PA behaviors based on the conceptual framework of health and its determinants. According to the participants, health is the autonomy to live without pain by maintaining a balance between physical and psychological aspects, eating healthy and exercising. Family and work influence participants' PA and eating behaviors. Exploring First Nations people's beliefs and perceptions and the motivations underlying their health behaviors could help encourage the maintenance of a healthy lifestyle despite multiple chronic health conditions.

RESUMO

Evidence on the individual-level drivers of dietary behaviours in deprived urban contexts in Africa is limited. Understanding how to best inform the development and delivery of interventions to promote healthy dietary behaviours is needed. As noncommunicable diseases account for over 40% of deaths in Ghana, the country has reached an advanced stage of nutrition transition. The aim of this study was to identify individual-level factors (biological, demographic, cognitive, practices) influencing dietary behaviours among adolescent girls and women at different stages of the reproductive life course in urban Ghana with the goal of building evidence to improve targeted interventions. Qualitative Photovoice interviews (n = 64) were conducted in two urban neighbourhoods in Accra and Ho with adolescent girls (13-14 years) and women of reproductive age (15-49 years). Data analysis was both theory- and data-driven to allow for emerging themes. Thirty-seven factors, across four domains within the individual-level, were identified as having an influence on dietary behaviours: biological (n = 5), demographic (n = 8), cognitions (n = 13) and practices (n = 11). Several factors emerged as facilitators or barriers to healthy eating, with income/wealth (demographic); nutrition knowledge/preferences/risk perception (cognitions); and cooking skills/eating at home/time constraints (practices) emerging most frequently. Pregnancy/lactating status (biological) influenced dietary behaviours mainly through medical advice, awareness and willingness to eat foods to support foetal/infant growth and development. Many of these factors were intertwined with the wider food environment, especially concerns about the cost of food and food safety, suggesting that interventions need to account for individual-level as well as wider environmental drivers of dietary behaviours.

RESUMO

BACKGROUND: Given the role of dietary antioxidants in relieving depression, anxiety, and stress, as well as studies on the beneficial effects of the Mediterranean and Dash diets separately on these problems, in this study, we examine the relationship between the MIND index (Mediterranean- DASH diet Intervention for Neurodegenerative Delay) as a combined indicator of the Mediterranean and DASH diet with psychological disorders such as depression, anxiety, and psychological stress among a large sample of the Iranian adult population. METHODS: This cross-sectional study was performed on 7165 participants of the enrollment phase of Yazd Health Study (YaHS) and Yazd Nutrition Study (TAMYZ) a valid 178-item semi-quantitative food frequency questionnaire (FFQ) was used to assess participants' food intake. The MIND diet score was calculated based on participants' dietary intakes obtained from FFQ. Also, the valid Iranian version of the Depression, Anxiety, and Stress Scale (DASS 21) was used to assess psychological disorders and stress. In addition, the association between the MIND diet and psychological disorders and stress was assessed through logistic regression. RESULTS: The mean ± SD score was 3.33 ± 3.79 for depression, 2.99 ± 3.65 for anxiety, and 5.93 ± 4.70 for psychological stress. The mean score of MIND in this study was 7.56. After adjustment for after adjusting for age, gender, intake of energy, BMI, history of chronic disease, marital status, education level, smoking history, physical activity level, pregnancy or lactation, intakes of dietary EPA, DHA, and fiber, individuals in highest compared to the lowest quartile of MIND diet score had significantly lower odds of depression (OR = 0.62, 95% CI 0.40 - 0.96; P-trend = 0.02) and anxiety (OR = 0.61, 95% CI 0.41 - 0.91; P-trend = 0.01). However, no significant association was observed for psychological stress (OR = 0.57, 95% CI 0.28 - 1.14; P-trend = 0.83). CONCLUSION: Therefore, it seems that following the MIND diet can prevent the possibility of these psychological problems. However, there is a need to design studies with more robust methodologies such as clinical trial studies.

RESUMO

PURPOSE: Growing evidence suggests that specific food groups may play an important role in improving mental health. However, very few studies explored the association between individual dietary factors and depression symptoms by following a large cohort of individuals over a long period. We examined the differential effects of fruit and vegetables in relation to depression symptoms over a 15-year follow-up period in the 1973-78 cohort of the Australian Longitudinal Study on Women's Health. METHODS: Fruit and vegetable consumption was assessed using short questions. The Center for Epidemiologic Studies Depression-10 scale with a cut off ≥ 10 indicated depressive symptoms. Multiple imputations with generalised estimating equations models were performed to estimate odds ratio of depression symptoms according to fruit and vegetable consumption. RESULTS: A total of 4241 participants with a mean age of 27.6 (SD 1.45) years at baseline were followed up at five surveys (2003-2018). Fruit and vegetable intake (≥ 2 servings) was cross-sectionally associated with lower odds of depressive symptoms. In longitudinal analysis, a higher intake of fruit (≥ 4 servings) and vegetable (≥ 5 servings) was consistently associated with lower odds of depressive symptoms, with a 25% lower odds (OR 0.75; 95% CI 0.57, 0.97; p = 0.031) and a 19% lower odds (OR 0.81; 95% CI 0.70, 0.94; p = 0.007) than consuming one serve or less fruit and vegetable, respectively. CONCLUSION: These results suggest that a higher intake of fruit and vegetables was associated with a lower risk of depression symptoms over 15 years from a population-based prospective study of Australian women.

RESUMO

OBJECTIVE: Examine the relationships among dietary quality, mindful eating, and constructs of the Transactional Model of Stress and Coping. METHODS: In this cross-sectional study, women (n = 67) aged 25-50 years, with a body mass index of 25-40 kg/m2 completed 3 days of 24-hour recalls and a survey that included the Perceived Stress Scale, Eating and Appraisal Due to Emotions and Stress Questionnaire, and the Mindful Eating Questionnaire. Structural equation modeling assessed relationships among all constructs with the dependent variable, the Healthy Eating Index-2015. RESULTS: Mindful Eating Questionnaire (ß = 0.60, P = 0.001) and Emotion and Stress-related Eating scores from Eating and Appraisal Due to Emotions and Stress Questionnaire (ß = -0.69, P < 0.001) (r2 = 0.50) were directly associated with Healthy Eating Index-2015, but no indirect effects were identified. CONCLUSIONS AND IMPLICATIONS: Overall dietary quality is associated with greater mindful eating but more emotion and stress-related eating scores among women who were overweight or obese. Future studies could assess model constructs using other diet quality scores and including additional coping mechanisms such as substance use, physical activity, and meditation.

RESUMO

INTRODUCTION: Fruit and vegetable consumption (FVC) continues to be low, particularly among people living in under-resourced communities. Identifying barriers and facilitators of FVC and whether those barriers and facilitators differ for racially and ethnically minoritized people is imperative for developing effective and equitable public health policies and interventions. METHODS: A baseline cohort of 390 participants from Central Texas communities historically lacking healthy food retailers completed a survey including FVC, 7 psychosocial barriers and facilitators of FVC, distance to a grocery retailer, participation in government assistance programs, and race/ethnicity. RESULTS: Not having time to prepare fruits and vegetables was the only significant psychosocial barrier identified (B = -.11, t(390) = 2.04, P = .04), but was not significant after accounting for sociodemographic variables. Significant facilitators of daily FVC were liking F&V (B=.31, t(390) = 6.40, P<.001), participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) (B=.14, t(390) = 2.81, P = .005), and Hispanic/Latino(a) ethnicity (B = -.21, t(390) = 4.30, P<.001). The final model accounted for 17% of the variance in daily FVC (R2=.17, F(4, 375) = 7.69, P < .001). Black, white and Other race participants were more likely to report having difficulty using F&V before spoiling than Hispanic/Latino(a) participants (P = .003). White and Other race participants were more likely to report that F&V were hard to prepare (P = .006) and that they didn't have time to prepare F&V (P = .005). DISCUSSION: When designing public health policy and interventions to increase FVC, researchers could prioritize identifying ways to alleviate time constraints, increase F&V liking, and help eligible participants to enroll in WIC. Strategies that reduce the risk of F&V spoiling and make F&V easier to prepare may also benefit some groups.

RESUMO

INTRODUCTION: Non-communicable diseases have risen markedly over the last decade. A phenomenon that was mainly endemic in high-income countries has now visibly encroached on low and middle-income settings. A major contributor to this is a shift towards unhealthy dietary behavior. This study aimed to examine the complex interplay between people's characteristics and the environment to understand how these influenced food choices and practices in Western Kenya. METHODS: This study used semi-structured guides to conduct in-depth interviews and focus group discussions with both male and female members of the community, across various socioeconomic groups, from Kisumu and Homa Bay Counties to further understand their perspectives on the influences of dietary behavior. Voice data was captured using digital voice recorders, transcribed verbatim, and translated to English. Data analysis adopted an exploratory and inductive analysis approach. Coded responses were analyzed using NVIVO 12 PRO software. RESULTS: Intrapersonal levels of influence included: Age, the nutritional value of food, occupation, perceived satiety of some foods as opposed to others, religion, and medical reasons. The majority of the participants mentioned location as the main source of influence at the community level reflected by the regional staple foodscape. Others include seasonality of produce, social pressure, and availability of food in the market. Pricing of food and distance to food markets was mentioned as the major macro-level influence. This was followed by an increase in population and road infrastructure. CONCLUSION: This study demonstrated that understanding dietary preferences are complex. Future interventions should not only consider intrapersonal and interpersonal influences when aiming to promote healthy eating among communities but also need to target the community and macro environments. This means that nutrition promotion strategies should focus on multiple levels of influence that broaden options for interventions. However, government interventions in addressing food access, affordability, and marketing remain essential to any significant change.

RESUMO

Overconsumption of red and processed meat is associated with a multitude of negative health outcomes. Previous research shows exposure to advertising messaging can influence dietary behaviors but research on the influence of meat advertising on diet, specifically, is scant. Theoretically informed by the Reasoned Action Approach, the present experiment randomly assigned participants to view a version of a print McDonald's advertisement that included meat imagery (a Big Mac), non-meat imagery (French fries), or no food (just the McDonalds' logo and slogan), which acted as a control. An online survey in the United States included 514 U.S. adults (Mage = 51 years). Participants exposed to meat imagery compared to the non-meat imagery reported a higher desire to eat meat. The meat imagery and control conditions were also significantly associated with increased cognitive accessibility of meat concepts, compared to when respondents were shown the no-meat condition. Desire to eat meat, but not the cognitive accessibility of meat concepts, was significantly associated with attitude, normative pressure, and perceived behavioral control for avoiding eating meat one day per week; these constructs predicted intention and willingness to avoid meat. Results indicate that exposure to meat imagery in advertising does have the potential to influence meat consumption behavior and also has implications for the use of meat imagery in persuasive messaging for public health campaigns.

RESUMO

Background: In this study, we explored the factors that motivate food choice, and evaluated the psychometric properties and demographic correlates of the Eating Motivation (EATMOT) questionnaire in adults in the United States (US). Methods: This cross-sectional survey involved 905 adults in 6 sites across the US. The EATMOT questionnaire measures participants' self-reported motivations for food selection, demographic, and anthropometric data. Analyses included exploratory and confirmatory factor analyses, correlations, Welch's t-tests, and logistic regressions. Results: We established a 3-factor model (health-related, emotional, and environmental/political motivations) as the best fit to the data (CFI = .983, RMSEA = .049, SRMR = .054). Gender differences were found within the 3 factors, as well as in the intercorrelations between factors. Higher levels of health-related motivations (B = .10, SE = .04, OR = 1.11 (95% CI: 1.03, 1.19), p = .006) were associated with increased reports of weight loss dieting, whereas higher levels of environmental/political motivations (B = -.09, SE = .04, OR = 0.91, p = .02) were associated with fewer reports of weight-loss dieting. Conclusion: An abbreviated version of the EATMOT scale is appropriate for use in a US sample and identifies 3 categories of factors that impact dietary choices. These factors may be important in building interventions to improve diets.

RESUMO

Food neophobia is the tendency to reject or be reluctant to try new and unfamiliar foods. Due to the period of its occurrence, which falls in the years of early childhood, it can significantly affect the child's food choices, shape taste preferences, and significantly influence the quality of the child's diet. The neophobic attitude has an important evolutionary significance because it protects the individual from ingesting potentially dangerous substances. On the other hand, it fosters avoidance behaviors that can also relate to the beneficial aspects of obtaining and consuming food. Currently, the strong emphasis placed on food safety means that neophobia may be less adaptive; nevertheless, a conservative attitude toward new foods still prevails. There is a strong association between food neophobia and the diversity of a person's diet and previous exposure to different foods. This review describes behaviors associated with food neophobia and analyzes other feeding and eating difficulties in children that should be differentiated from food neophobia. Management approaches affecting the reduction in food neophobia in children through various dietary and psychological interventions are also proposed.

RESUMO

Young Australian adults' exhibit high consumption of Energy Dense and Nutrient Poor (EDNP) foods; however, there is limited research concerning the factors influencing their consumption. This study aimed to explore socio-psychological factors associated with young Australian adults' (18-30 years) consumption of EDNP foods with consideration of the Food Related Lifestyle Model (FRLM) as a potential framework. Through qualitative descriptive research methodology, 38 young adults were interviewed. Data were thematically analyzed. Participants were classified into three groups based on their living arrangements namely, parental, shared and independent households. Five themes emerged, (1) psychological factors (2) intrinsic qualities of EDNP foods, (3) social factors, (4) accessibility and affordability and (5) health related beliefs. The FRLM takes into consideration some of the factors reported in this study as influencers of EDNP food intakes. However, the FRLM omits important psychological factors (motivation, restraint, cravings, coping strategies and habits) identified by participants as influencers over their EDNP food intakes. The FRLM may need to be extended in its application to EDNP food intakes of young Australian adults. Social marketing campaigns highlighting health risks, addressing social and environmental factors are suggested. The social desirability of healthier alternatives in social gatherings of young adults could be increased.

RESUMO

BACKGROUND: Consistent participation in colorectal cancer (CRC) screening with repeated fecal immunochemical test (FIT) is important for the success of the screening program. We investigated whether lifestyle risk factors for CRC were related to inconsistent participation in up to four rounds of FIT-screening. METHOD: We included data from 3,051 individuals who participated in up to four FIT-screening rounds and returned a lifestyle questionnaire. Using logistic regression analyses, we estimated associations between smoking habits, body mass index (BMI), physical activity, alcohol consumption, diet and a healthy lifestyle score (from least favorable 0 to most favorable 5), and inconsistent participation (i.e. not participating in all rounds of eligible FIT screening invitations). RESULTS: Altogether 721 (24%) individuals were categorized as inconsistent participants Current smoking and BMI ≥30 kg/m2 were associated with inconsistent participation; odds ratios (ORs) and 95% confidence intervals (CIs) were 1.54 (1.21-2.95) and 1.54 (1.20-1.97), respectively. A significant trend towards inconsistent participation by a lower healthy lifestyle score was observed (p < 0.05). CONCLUSIONS: Lifestyle behaviors were associated with inconsistent participation in FIT-screening. Initiatives aimed at increasing participation rates among those with the unhealthiest lifestyle have a potential to improve the efficiency of screening.

RESUMO

Youth obesity has become increasingly prevalent, with 34.5% of US adolescents 12-19 years old estimated to have overweight or obesity. Disordered eating and weight concern peak in adolescence, and overeating to cope with negative emotions can affect long-term health and obesity risk. Parents significantly influence adolescent diet quality, and parental stress may influence parenting behaviors that increase the risk for stress-motivated eating and obesity in adolescents. Chronic or repeated exposure to parental stress may lead to stress-related neurophysiological changes that promote consumption of palatable foods and obesogenic eating habits in adolescents. Understanding how parental stress influences adolescents' eating behavior may reveal novel access points for reducing adolescent obesity. Here, we aim to provide a new stress-focused framework for developing intervention strategies targeted at obesity prevention in adolescents.
