RESUMO

Time-restricted eating (TRE), a dietary strategy that involves limiting daily energy intake to a window of ≤12 h is appealing for weight management and metabolic health due to its relative simplicity and the ability to consume ad libitum diet during eating windows. Despite the potential utility of TRE for improving health and reducing disease, the feasibility of adherence depends upon a variety of multilevel factors which are largely unexplored. The primary aim of our study was to explore facilitators and barriers of adherence to TRE among community-dwelling individuals. Semi-structured qualitative interviews were conducted among 24 individuals (50% male; M age: 34, range: 18-57; 58% overweight/obese) who currently or formerly practiced TRE. Thematic analysis identified facilitators of and barriers to TRE adherence at multiple levels of influence (i.e., biological, behavioral, psychosocial, environmental). Key facilitators of adherence included improvements in physical health and energy levels, alignment with other aspects of diet, exercise and sleep patterns, self-monitoring and positive psychological impacts, social support, and busy or regular schedules. Key barriers included negative physical health effects, feelings of hunger and sluggishness, difficulty in skipping valued baseline eating routines or inadequate diet quality during the eating window, misalignment of TRE with 24-h activity behaviors, difficulties with self-monitoring, the need to mitigate negative feelings, social situations that discourage TRE, and irregular or idle schedules. Results illustrate that key drivers of adherence differ across individuals and their unique settings and that multiple drivers of behavior should be considered in the successful implementation of TRE. Findings may inform interventions seeking to tailor TRE schedules to fit individuals' diverse behavioral patterns and preferences, thereby optimizing adherence.

RESUMO

OBJECTIVE: The present study aimed to examine the correlates of fruit and vegetable intake (FVI) separately among parents and their adolescents. DESIGN: Cross-sectional surveys. SETTING: Online survey. SUBJECTS: Parents and adolescents completed the Family Life, Activity, Sun, Health, and Eating (FLASHE) survey through the National Cancer Institute. The survey assessed daily intake frequencies of food/beverage groups, psychosocial, parenting and sociodemographic factors. Generalized linear models were run for both parents and adolescents, for a total of six models (three each): (i) sociodemographic characteristics; (ii) psychosocial factors; (iii) parent/caregiver factors. RESULTS: Parent participants (n 1542) were predominantly 35-59 years old (86 %), female (73 %), non-Hispanic White (71 %) or non-Hispanic Black (17 %), with household income <$US 100 000 (79 %). Adolescents (n 805) were aged 12-14 years (50 %), non-Hispanic White (66 %) and non-Hispanic Black (15 %). Parents consumed 2·9 cups fruits and vegetables (F&V) daily, while adolescents consumed 2·2 cups daily. Educational attainment (higher education had greater FVI) and sex (men consumed more than women; all P<0·001) were significant FVI predictors. Parents with greater autonomous and controlled motivation, self-efficacy and preferences for fruit reported higher FVI (all P<0·001). Similarly, adolescents with greater autonomous and controlled motivation, self-efficacy and knowledge reported higher FVI (all P<0·001). Parenting factors of importance were co-deciding how many F&V teens should have, rules, having F&V in the home and cooking meals from scratch (all P<0·05). CONCLUSIONS: Findings suggest factors that impact FVI among parents and their adolescent(s), which highlight the importance of the role of parent behaviour and can inform tailored approaches for increasing FVI in various settings.

RESUMO

Obesity among adolescents in the United States has risen by 16% in the past 30 years. One important contributing factor may be the increased consumption of sugar sweetened beverages (SSBs), which is encouraged by advertisements for unhealthy foods and drinks that are targeted to adolescents. The purpose of this analysis was to determine the association between susceptibility to food and drink advertisements and sugar-sweetened beverage (SSB) consumption in non-Hispanic black (NHB) and non-Hispanic white (NHW) adolescents and to examine if BMI is associated with SSB consumption. Data were obtained from 765 NHB and NHW of ages 14-17 who were surveyed in the Family Life, Activity, Sun, Health, and Eating study sponsored by the National Cancer Institute. Two weighted adjusted logistic regression models were conducted. The first examined the associations of advertisement susceptibility, race, and BMI with SSB consumption. The second examined the associations of race and BMI with advertisement susceptibility. Adolescents with high advertisement susceptibility were more likely to consume at least one SSB daily (OR 1.73, 95% CI 1.21, 2.47). Additionally, non-Hispanic blacks were more likely to consume at least one SSB daily (OR 1.75, 95% CI 1.08, 2.85) and more likely to be highly susceptible to advertisements (OR 1.72, 95% CI 1.19, 2.48) than non-Hispanic whites. No significant associations were found between BMI and advertising susceptibility or BMI and daily SSB consumption. One approach to addressing the consumption of SSBs may be to reduce advertising that markets unhealthy food and beverages to adolescents and minorities.

RESUMO

The advertising and marketing of energy-dense, nutrient-poor (EDNP) food and drink has been cited as one contributor to unhealthy eating behaviors in adolescents. The present study examines perceptions about and trust in food advertising and their association with consumption of EDNP foods and drinks among adolescents in the United States. Data (n = 1,384) come from the U.S. National Cancer Institute's Family Life, Activity, Sun, Health, and Eating Survey. One way ANOVAs were conducted to assess differences between population subgroups in advertising perceptions. Bivariate and multivariable linear regression models were used to examine the associations between perceptions toward and trust in food advertising and consumption of EDNP foods and drinks, controlling for sociodemographic factors. Results show that there are significant differences between racial/ethnic groups on advertising perceptions (F = 16.32, p = < .0001). As positive perceptions toward food advertising increase among adolescents, there is an associated increase in daily frequency of consumption of EDNP foods and drinks (ß = 0.10, p < .01). Similarly, the more adolescents agreed that they trusted food advertising, the higher the reported daily frequency of EDNP food and drink consumption (ß = 0.08, p = .01). Targeting perceptions about food advertising may be a worthy intervention strategy to reduce the impact of food marketing and the consumption of heavily advertised EDNP foods and drinks among adolescents.

RESUMO

Despite knowing that fruit and vegetable (FV) intake promotes health and well-being, few U.S. adults meet current guidelines. Thus, understanding people's motivation for FV intake is important for predicting dietary behavior. Applying self-determination theory, the goal of this study was to examine the role of social support as a potential moderator of the link between autonomous and controlled motivations and FV intake. Cross-sectional data from 2959 adults in the United States were analyzed. Autonomous motivation and perceived social support were positively associated with FV intake, while controlled motivation was negatively associated with FV intake. Additionally, there was evidence that the negative association between controlled motivation and FV intake was attenuated by higher levels of perceived social support. Findings suggest the need for a more comprehensive approach to understanding the role of motivation in health behaviors like FV intake and the potential roles played by friends and family in these motivational processes.

RESUMO

Structural racism has been identified as a fundamental cause of health disparities. For example, racial, ethnic, and economic neighborhood segregation; concentrated poverty; community disinvestment; and sociocultural context influence obesity and cancer disparities. Effects of structural racism are also evident through neighborhood obesogenic conditions such as limited access to affordable and healthy foods and physical activity opportunities within segregated communities that contribute to obesity and obesity-related cancer disparities. This article describes and expands on cross-cutting themes raised during a webinar held by the National Cancer Institute (NCI): (1) how structural factors, including neighborhood segregation and obesogenic conditions within racial and ethnic disadvantaged communities, influence disparities in the United States; (2) current research challenges and best ways to address them; and (3) selected priorities of the NCI aimed at addressing multilevel and intersecting factors that influence obesity-related cancer disparities. Further research is needed to understand how residential segregation and neighborhood obesogenic conditions influence cancer prevention and control across the continuum. Identifying the best approaches to address obesity and cancer disparities using social determinants of health framework and community-engaged approaches guided by a structural racism lens will allow researchers to move beyond individual-level approaches.

RESUMO

BACKGROUND: Time-restricted eating (TRE), a type of intermittent fasting in which all daily calories are consumed within a window of ≤12 hours, is hypothesized to promote long-term weight management because of its relative simplicity. OBJECTIVE: This study reports correlates of adherence among community-dwelling adults currently or formerly following a TRE dietary strategy. DESIGN: A 25-minute cross-sectional online survey was developed, including questions about TRE perceptions, behaviors, motivators and drivers, and demographics. The survey was administered in February 2021 via Prolific, an online platform for sample recruitment and survey dissemination. PARTICIPANTS: Eligibility criteria included US adult ages 18+ who currently or formerly (past 3 months) followed TRE (ie, consumed all daily calories within a window of ≤12 hours) for a minimum of 1 week. STATISTICAL ANALYSES: χ2 tests and analysis of covariance (ANCOVA; adjusting for sex and age) compared responses between current and former followers. RESULTS: Current followers (n = 296, mean [SD]: 34.2 ± 12.2y) were older than former followers (n = 295, mean [SD]: 31.1 ± 10.9 y) and practiced TRE for longer (median: 395 vs 90 days, P < 0.001). Current followers reported more success with meeting TRE goals (P ≤ 0.015), were less likely to report TRE concerns (P < 0.001), and more likely to report TRE satisfaction (P < 0.001). Four TRE motivators were more important among current (vs former) followers: weight maintenance, health (not weight), improved sleep, and preventing disease (P ≤ 0.017); weight loss was more important among former (vs current) followers (P = 0.003). Among adherence drivers, ability to work from home and the impact of COVID-19 were reported as more helpful for TRE adherence among current compared with former followers (P ≤ 0.028). CONCLUSIONS: TRE motivators and drivers differed between current and former followers; interventions tailored to individuals' preferences and circumstances may benefit TRE adherence.

RESUMO

With the escalating prevalence of obesity, the association between obesity and cancer is a growing public health concern. Obesity will soon surpass tobacco smoking as the most important preventable cause of cancer. Obesity-driven mechanisms can alter cell functions to induce metabolic changes, chronic inflammation, and insulin resistance that are believed to contribute to cancer risk and development; yet the specific underlying biological mechanisms of obesity-related cancer development are largely unknown. The Metabolic Dysregulation and Obesity Cancer Risk (MeDOC) Program is a trans-NCI research program supported by the Division of Cancer Control and Population Sciences, the Division of Cancer Biology, the Division of Cancer Prevention, and the Center to Reduce Cancer Health Disparities. The overall purpose of the MeDOC Program is to advance our understanding of the underlying mechanisms that connect obesity, metabolic dysregulation, and increased obesity cancer risk, as well as identify markers that will enhance cancer risk prediction, improve screening for high-risk individuals, and identify targets for preventive and therapeutic interventions for cancer interception or treatment. This report describes the funded research projects, the Coordinating Center, and the goals of the MeDOC Program.

RESUMO

Given the high and growing prevalence of obesity among adults in the United States, obesity treatment and prevention are important topics in biomedical and public health research. Although researchers recognize the significance of this problem, much remains unknown about safe and effective prevention and treatment of obesity in adults. In response to the worsening obesity epidemic and the many unknowns regarding the disease, a group of key scientific and program staff members of the National Institutes of Health (NIH) and other federal and non-government agencies gathered virtually in September 2021 to discuss the current state of obesity research, research gaps, and opportunities for future research in adult obesity prevention and treatment. The current article synthesizes presentations given by attendees and shares their organizations' current initiatives and identified gaps and opportunities. By integrating the information discussed in the meeting and current initiatives, we identify potential targets and overlapping priorities for future research, including health equity and disparities in obesity, the heterogeneity of obesity, and the use of technological and innovative approaches in interventions.

RESUMO

INTRODUCTION: Water is vital for life, and plain water is a calorie-free option for hydration. Increasing consumption of drinking water is a strategy to reduce energy intake and lose or maintain weight; however, information on the characteristics of consumers who drink water is limited. Our objective was to describe the characteristics of people who have a low intake of drinking water and to determine associations between their behaviors and attitudes and their intake of water. METHODS: We analyzed data from a nationally representative sample of 3,397 US adults who participated in the National Cancer Institute's 2007 Food Attitudes and Behaviors Survey. Multivariable logistic regression was used to identify sociodemographic characteristics and health-related behaviors and attitudes associated with self-reported drinking water intake of less than 4 cups per day. RESULTS: Overall, 7% of adults reported no daily consumption of drinking water, 36% reported drinking 1 to 3 cups, 35% reported drinking 4 to 7 cups, and 22% reported drinking 8 cups or more. The likelihood of drinking less than 4 cups of water daily was significantly higher among participants aged 55 years or older than among those aged 18 to 34 (adjusted odds ratio [AOR], 1.3), among residents of the Northeast than among residents of the South (AOR, 1.4), among participants who consumed 1 cup or less of fruits or vegetables per day than among those who consumed 4.5 cups or more (AOR, 3.0), among participants who did not exercise than among those who exercised 150 minutes or more per week (AOR, 1.7), and among participants who were neither trying to gain nor lose weight than among those trying to lose weight (AOR, 1.3). CONCLUSION: Low drinking water intake was associated with age, region of residence, and several unhealthful behaviors and attitudes. Understanding characteristics associated with low drinking water intake may help to identify populations that could benefit from interventions to help adults drink more water.

RESUMO

OBJECTIVES: We examined whether public schools in states with specific and stringent physical education (PE) laws, as assessed by the Physical Education-Related State Policy Classification System (PERSPCS), available on the Classification of Laws Associated with School Students (C.L.A.S.S.) Web site, reported more weekly PE time in the most recent School Health Policies and Programs Survey (SHPPS). METHODS: Schools (n=410) were grouped by their state's PERSPCS time requirement scores (none, nonspecific requirement, or specific requirement). Average weekly school-level PE was calculated using the SHPPS-reported PE minutes. Weighted analyses determined if PE minutes/week differed by PERSPCS group. RESULTS: Schools in states with specific requirement laws averaged over 27 and 60 more PE minutes/week at the elementary and middle school levels, respectively, compared with schools within states with nonspecific laws and over 40 and 60 more PE minutes per week, respectively, compared with elementary and middle schools in states with no laws. High school results were nonsignificant. CONCLUSIONS: Public health guidelines recommend at least 60 minutes of daily physical activity for children, and PE may further this goal. Strong codified law with specific time requirements for PE may be an important tool contributing toward adequate PE time and daily physical activity recommendations.

RESUMO

Increased consumption of fruits and vegetables is recommended to reduce chronic disease risk. Few studies have examined awareness of the current fruit and vegetable campaign in the United States, Fruits and Veggies-More Matters. This study assessed awareness of the Fruits and Veggies-More Matters campaign and knowledge of the 7-13 serving recommendation for fruit and vegetable consumption among adults, and determined whether these were associated with fruit and vegetable intake. Cross-sectional data from 3021 adults in the United States' National Cancer Institute's 2007 Food Attitudes and Behaviors Survey were analyzed. Few participants were aware of the Fruits and Veggies-More Matters campaign (2%) and the 7-13 recommendation (6%) for adults. More participants were aware of the former 5 A Day campaign (29%) and recommendation (30%). Thirty-nine percent reported consuming ≥5 servings of fruits and vegetables daily. Participants were more likely to consume ≥5 servings of fruits and vegetables/day if they were aware of the 5 A Day/Fruits and Veggies-More Matters campaign, and reported that the recommendation for adults was ≥5 servings/day. Findings suggest the need to increase awareness of the Fruits and Veggies-More Matters campaign, and the 7-13 recommendation among adults to support high fruit and vegetable intake.

RESUMO

Few studies have examined the influence of acculturation on dietary behaviors of young children while controlling for other demographic variables. The purpose of this study was to assess reported dietary intakes of preschool-aged children (3-5 years) and subsequent associations with caregivers' race/ethnicity, acculturation and demographic characteristics, using data from the 2007 California Health Interview Survey (CHIS). Analysis was restricted to Hispanic and non-Hispanic white caregivers and their preschool-aged children (n = 1,105). Caregivers' acculturation was assessed using place of birth, duration of United States residence, and language spoken at home. Proxy-reports by caregivers to a dietary screener were used to estimate children's intakes of fruit, 100% fruit juice, vegetables, sweets, and sugar-sweetened beverages consumed. In multivariate analyses, Hispanic caregivers reported their children consumed fewer servings of vegetables than did the children of non-Hispanic white caregivers; there were no other statistically significant differences in children's dietary intakes by caregivers' race/ethnicity. Caregivers' acculturation was associated with caregiver-reported consumption of sweets by children (ß = 0.09, 95%CI = 0.01-0.18). Demographic characteristics that were associated with reported dietary intakes of children included caregivers' age, education, and geographic region of residence. In contrast to past studies of acculturation and diet in older children and adults, this study suggests that for 3-5 year olds, caregivers' level of acculturation does not play as strong a role in the dietary intakes of the younger children under their care.

RESUMO

Consumption of diets high in fruits and vegetables is associated with reduced risk of chronic diseases, and self-efficacy and the food environment influence consumption of fruits and vegetables. We analyzed data from 3,021 non-Hispanic white (n = 2,187) and non-Hispanic black (n = 834) US adults who responded to National Cancer Institute's 2007 Food Attitudes and Behaviors Survey to assesss self-efficacy and perception of the food environment. Adults who perceived that it was easy to obtain fruits and vegetables when they ate out reported greater self-efficacy to consume fruits and vegetables than did participants who did not have this perception (odds ratio [OR] = 1.56, 95% confidence interval [CI], 1.24-1.97). However, adults who perceived that fruits were not available at restaurants where they ate out (OR = 0.65, 95% CI, 0.50-0.86) or that other (ie, non-fast food) restaurants offered enough choices of fruits and vegetables on their menus (OR = 0.76, 95% CI, 0.61-0.97) reported lower self-efficacy to consume fruits and vegetables than did participants who did not have these perceptions. Findings suggest that perceptions about availability of fruits and vegetables in restaurants are important to promote self-efficacy for consuming fruits and vegetables among adults.

RESUMO

It is estimated that behaviors such as poor diet, alcohol consumption, tobacco use, sedentary behavior, and excessive ultraviolet exposure account for nearly one-half of all cancer morbidity and mortality. Accordingly, the behavioral, social, and communication sciences have been important contributors to cancer prevention and control research, with methodological advances and implementation science helping to produce optimally effective interventions. To sustain these contributions, it is vital to adapt to the contemporary context. Efforts must consider ancillary effects of the 2019 coronavirus disease pandemic, profound changes in the information environment and public understanding of and trust in science, renewed attention to structural racism and social determinants of health, and the rapidly increasing population of cancer survivors. Within this context, it is essential to accelerate reductions in tobacco use across all population subgroups; consider new models of energy balance (diet, physical activity, sedentary behavior); increase awareness of alcohol as a risk factor for cancer; and identify better communication practices in the context of cancer-related decisions such as screening and genetic testing. Successful integration of behavioral research and cancer prevention depends on working globally and seamlessly across disciplines, taking a multilevel approach where possible. Methodological and analytic approaches should be emphasized in research training programs and should use new and underused data sources and technologies. As the leadership core of the National Cancer Institute's Behavioral Research Program, we reflect on these challenges and opportunities and consider implications for the next phase of behavioral research in cancer prevention and control.

RESUMO

Medical image interpretation is central to detecting, diagnosing, and staging cancer and many other disorders. At a time when medical imaging is being transformed by digital technologies and artificial intelligence, understanding the basic perceptual and cognitive processes underlying medical image interpretation is vital for increasing diagnosticians' accuracy and performance, improving patient outcomes, and reducing diagnostician burnout. Medical image perception remains substantially understudied. In September 2019, the National Cancer Institute convened a multidisciplinary panel of radiologists and pathologists together with researchers working in medical image perception and adjacent fields of cognition and perception for the "Cognition and Medical Image Perception Think Tank." The Think Tank's key objectives were to identify critical unsolved problems related to visual perception in pathology and radiology from the perspective of diagnosticians, discuss how these clinically relevant questions could be addressed through cognitive and perception research, identify barriers and solutions for transdisciplinary collaborations, define ways to elevate the profile of cognition and perception research within the medical image community, determine the greatest needs to advance medical image perception, and outline future goals and strategies to evaluate progress. The Think Tank emphasized diagnosticians' perspectives as the crucial starting point for medical image perception research, with diagnosticians describing their interpretation process and identifying perceptual and cognitive problems that arise. This article reports the deliberations of the Think Tank participants to address these objectives and highlight opportunities to expand research on medical image perception.

RESUMO

Attention to cancer-relevant communication (e.g., fruit/vegetable intake recommendations) through various media has been shown to be a pivotal step in reduction of the cancer burden, thus underscoring the importance of examining associations between exposure to health media and knowledge of and adherence to fruit/vegetable intake recommendations. The purpose of the present study was to assess factors associated with fruit/vegetable intake knowledge and behavior. The authors analyzed data collected from the 2003 Health Information National Trends Survey to evaluate the effect of fruit/vegetable intake knowledge on behavior, and the relationship of this effect with biobehavioral, sociodemographic, and communication characteristics. Participants who were knowledgeable of fruit/vegetable intake recommendations and consumed at least 5 fruit/vegetable servings per day were classified as informed compliers. Associations were observed for being an informed complier and paying "a lot" of attention to health media on the radio, in the newspaper, and in magazines and "a little" or "some" attention to health media in magazines or on the Internet. The recent explosion of available cancer-related information through various media underscores the importance of examining associations between exposure to health media and knowledge of and adherence to fruit/vegetable intake recommendations.

RESUMO

Improvements to the food environment including new store development and more farm-to-consumer approaches (ie, farmers' markets, roadside stands, pick-your-own produce farms, or community-supported agriculture programs) may aid Americans in making healthier dietary choices. We analyzed data from a subset of respondents (N = 1,994) in the National Cancer Institute's Food Attitudes and Behaviors Survey, a mail survey of US adults. We determined associations between primary grocery shoppers' region and sociodemographic characteristics and frequency of purchasing fruits and vegetables in the summer from farm-to-consumer venues. A little more than one-quarter (27%) of grocery shoppers reported a frequency of at least weekly use of farm-to-consumer approaches. Older adults and respondents who live in the Northeast were most likely to shop farm-to-consumer venues at least weekly, and no differences were found by sex, race/ethnicity, education, or annual household income. These findings suggest that farm-to-consumer venues are used by many Americans and could be expanded to increase access to fruits and vegetables.

RESUMO

Introduction: Neighborhood environment factors are relevant for dietary behaviors, but associations between home neighborhood context and disease prevention behaviors vary depending on the definition of neighborhood. The present study uses a publicly available dataset to examine whether associations between neighborhood socioeconomic status (NSES) and fruit/vegetable (FV) consumption vary when NSES is defined by different neighborhood sizes and shapes. Methods: We analyzed data from 1,736 adults with data in GeoFLASHE, a geospatial extension of the National Cancer Institute's Family Life, Activity, Sun, Health, and Eating Study (FLASHE). We examined correlations of NSES values across neighborhood buffer shapes (circular or street network) and sizes (ranging from 400 to 1,200 m) and ran weighted simple and multivariable regressions modeling frequency of FV consumption by NSES for each neighborhood definition. Regressions were also stratified by gender. Results: NSES measures were highly correlated across various neighborhood buffer definitions. In models adjusted for socio-demographics, circular buffers of all sizes and street buffers 750 m and larger were significantly associated with FV consumption frequency for women only. Conclusion: NSES may be particularly relevant for women's FV consumption, and further research can examine whether these associations are explained by access to food stores, food shopping behavior, and/or psychosocial variables. Although different NSES buffers are highly correlated, researchers should conceptually determine spatial areas a priori.

RESUMO

Energy imbalance increases cancer burden by increasing cancer risk and mortality. Training early career investigators on conducting impactful energy balance and cancer research is needed. We developed a Transdisciplinary Research in Energetics and Cancer (TREC) Training Program for early career investigators. This analysis examined program satisfaction, knowledge gained, publications, and awards among Year 1 participants (i.e., fellows). The program consists of an in-person course, followed by 1 year of mentorship. Faculty and fellows completed precourse and postcourse surveys. Following the mentorship period, we surveyed fellows for TREC-related research productivity, including publications and grant funding attributed to the program. Twenty fellows were accepted into the program: 3 basic, 7 clinical, and 10 population scientists. Sixteen fellows were junior faculty and four were postdoctoral fellows. The course included ~50 lectures, small group sessions, and faculty-fellow sessions. 96.7% of attendees rated the course in the highest categories of "good/very good." Knowledge significantly improved in 37 of 39 research competencies (94.8%). In the 18 months following the course, fellows published 25 manuscripts, with 3 published in journals with impact factor ≥10. Nineteen grants were funded to TREC fellows (i.e., 7 National Institutes of Health awards, 2 American Cancer Society [ACS] awards, and 10 foundation/pilot awards), and 7 fellows received career promotions. The program's impact will be defined by the degree to which TREC fellows produce discoveries that could improve the health of populations at risk for and/or surviving cancer. Upon the conclusion of our fifth year in 2021, we will publicly disseminate the program material.
