RESUMEN

BACKGROUND: Prepregnancy body mass index (BMI) and gestational weight gain (GWG) are determinants of maternal and child health. However, many studies of these factors rely on error-prone self-reported measures. METHODS: Using data from Life-course Experiences And Pregnancy (LEAP), a US-based cohort, we assessed the validity of prepregnancy BMI and GWG recalled on average 8 years postpartum against medical record data treated as alloyed gold standard ("true") values. We calculated probabilities of being classified into a self-reported prepregnancy BMI or GWG category conditional on one's true category (analogous to sensitivities and specificities) and probabilities of truly being in each prepregnancy BMI or GWG category conditional on one's self-reported category (analogous to positive and negative predictive values). RESULTS: There was a tendency toward under-reporting prepregnancy BMI. Self-report misclassified 32% (95% confidence interval [CI] = 19%, 48%) of those in LEAP with truly overweight and 13% (5%, 27%) with obesity into a lower BMI category. Self-report correctly predicted the truth for 72% (55%, 84%) with self-reported overweight to 100% (90%, 100%) with self-reported obesity. For GWG, both under- and over-reporting were common; self-report misclassified 32% (15%, 55%) with truly low GWG as having moderate GWG and 50% (28%, 72%) with truly high GWG as moderate or low GWG. Self-report correctly predicted the truth for 45% (25%, 67%) with self-reported high GWG to 85% (76%, 91%) with self-reported moderate GWG. Misclassification of BMI and GWG varied across maternal characteristics. CONCLUSION: Findings can be used in quantitative bias analyses to estimate bias-adjusted associations with prepregnancy BMI and GWG.

RESUMEN

INTRODUCTION: Firearms are now the number one killer of children and adolescents in the United States. Firearm homicides among Black male youth are the driver of this increase. Prevention requires a multi-faceted life course approach. Academic achievement has been identified as a protective factor. Early childhood education, which is linked to later achievement, is thus an intervention area of interest. Conceptualizing the potential links between early childhood education and reduced risk for youth firearm homicide is important for guiding policy advocacy and informing future research. METHODS: This paper presents a conceptual model linking early childhood education to reduced risk for firearm homicide. Each link in the model is discussed, and a corresponding review of the literature is presented. The need for anti-racist policies to strengthen the impact of early childhood education is highlighted. RESULTS: Early education and firearm homicide research are each well-established but largely disconnected. There are clear immediate benefits of early childhood education; however, these effects wane with time, particularly for youth of color. At the same time, juvenile delinquency-a major risk factor for firearm homicide-is influenced by educational inequities. CONCLUSIONS: Effective interventions to reduce firearm homicides among Black male youth in the United States are needed. Early childhood education shows promise as an intervention. However, to have an impact, this education needs to be accessible and affordable for all, particularly families of color and low income. Societal structures and policies must also better support the positive gains seen through early childhood education to avoid dissipation.

RESUMEN

Interest in using internet search data, such as that from the Google Health Trends Application Programming Interface (GHT-API), to measure epidemiologically relevant exposures or health outcomes is growing due to their accessibility and timeliness. Researchers enter search term(s), geography, and time period, and the GHT-API returns a scaled probability of that search term, given all searches within the specified geographic-time period. In this study, we detailed a method for using these data to measure a construct of interest in 5 iterative steps: first, identify phrases the target population may use to search for the construct of interest; second, refine candidate search phrases with incognito Google searches to improve sensitivity and specificity; third, craft the GHT-API search term(s) by combining the refined phrases; fourth, test search volume and choose geographic and temporal scales; and fifth, retrieve and average multiple samples to stabilize estimates and address missingness. An optional sixth step involves accounting for changes in total search volume by normalizing. We present a case study examining weekly state-level child abuse searches in the United States during the coronavirus disease 2019 pandemic (January 2018 to August 2020) as an application of this method and describe limitations.

RESUMEN

During apoptosis, the mitochondrial outer membrane is permeabilized, leading to the release of cytochrome c that activates downstream caspases. Mitochondrial outer membrane permeabilization (MOMP) has historically been thought to occur synchronously and completely throughout a cell, leading to rapid caspase activation and apoptosis. Using a new imaging approach, we demonstrate that MOMP is not an all-or-nothing event. Rather, we find that a minority of mitochondria can undergo MOMP in a stress-regulated manner, a phenomenon we term "minority MOMP." Crucially, minority MOMP leads to limited caspase activation, which is insufficient to trigger cell death. Instead, this caspase activity leads to DNA damage that, in turn, promotes genomic instability, cellular transformation, and tumorigenesis. Our data demonstrate that, in contrast to its well-established tumor suppressor function, apoptosis also has oncogenic potential that is regulated by the extent of MOMP. These findings have important implications for oncogenesis following either physiological or therapeutic engagement of apoptosis.

RESUMEN

OBJECTIVE: Low childhood socio-economic status (SES) and adverse childhood experiences (ACE) are associated with poor health outcomes in adulthood. Determining how ACE may be linked to food insecurity among young people from socio-economically diverse households can inform health-protective strategies. This study examined if ACE are associated with food insecurity during the transition to adulthood and investigated prevalence differences across SES strata. SETTING: Participants were recruited from twenty secondary schools in Minneapolis-St. Paul, Minnesota. PARTICIPANTS: The analytic sample (n 1518) completed classroom surveys in 2009-2010 (mean age = 14·5 years) and follow-up surveys in 2017-2018 (mean age = 22·0 years). DESIGN: Past-year food insecurity was reported at both time points, and ACE were reported at follow-up. Logistic regression models were used to estimate emerging adult food insecurity prevalence by ACE exposure; models were stratified by childhood SES (low, middle and high). RESULTS: The adjusted prevalence of food insecurity was 45·3 % among emerging adults who reported three or more ACE compared with 23·6 % among those with one or two ACE and 15·5 % among those with no ACE (P < 0·001). All forms of ACE were related to an elevated prevalence of food insecurity in emerging adulthood. ACE-food insecurity associations were strongest for emerging adults from lower and middle SES households. Among emerging adults from low SES households, childhood experiences of emotional abuse and substance use by a household member were associated with the largest prevalence differences in food insecurity. CONCLUSIONS: Findings suggest a need for trauma-informed services within food assistance programs to better serve individuals with a history of ACE.

RESUMEN

Economic hardship during childhood has been linked to poor physical and mental health. This study examines cross-sectional and longitudinal associations of a summed economic hardship score of poverty, food insecurity, and financial hardship with hair cortisol in young children. Data from 24-month (Time 1, mean age 5 years) and 36-month (Time 2, mean age 6 years) follow-up from the NET-Works obesity prevention trial (NET-Works, NCT0166891) were used. Hair cortisol measures obtained at each time point were log-transformed and regressed on economic hardship at Time 1 and a cumulative economic hardship from Time 1 to Time 2, using generalized linear regressions. All models were adjusted for child age, sex, race/ethnicity, and intervention (prevention vs. control) arm. The final analytic sample sizes ranged from 248 to 287. Longitudinal analyses indicated that for every 1-unit higher economic hardship score at Time 1, hair cortisol at Time 2 follow-up was on average 0.07 log-picograms per milligram (pg/mg) higher (95% confidence interval [CI]: 0.01, 0.13). For every 1-unit increase in the cumulative economic hardship score between Time 1 and 2, there was a 0.04 log-pg/mg (95% CI: 0.00, 0.07) average higher level of hair cortisol at Time 2 follow-up. Results show suggestive but limited evidence for an association between economic hardship and cortisol in young children.

RESUMEN

Substantial evidence suggests that economic hardship causes violence. However, a large majority of this research relies on observational studies that use traditional violence surveillance systems that suffer from selection bias and over-represent vulnerable populations, such as people of color. To overcome limitations of prior work, we employed a quasi-experimental design to assess the impact of the Great Recession on explicit violence diagnoses (injuries identified to be caused by a violent event) and proxy violence diagnoses (injuries highly correlated with violence) for child maltreatment, intimate partner violence, elder abuse, and their combination. We used Minnesota hospital data (2004-2014), conducting a difference-in-differences analysis at the county level (n = 86) using linear regression to compare changes in violence rates from before the recession (2004-2007) to after the recession (2008-2014) in counties most affected by the recession, versus changes over the same time period in counties less affected by the recession. The findings suggested that the Great Recession had little or no impact on explicitly identified violence; however, it affected proxy-identified violence. Counties that were more highly affected by the Great Recession saw a greater increase in the average rate of proxy-identified child abuse, elder abuse, intimate partner violence, and combined violence when compared with less-affected counties.

RESUMEN

Adverse childhood experiences (ACEs) include childhood abuse, neglect, and household substance abuse. Childhood abuse is a risk factor for disordered eating (DEB). Less well established are associations of childhood neglect and household substance abuse with DEB, and little research has examined ACE associations with DEB in middle adulthood. The objective of this study was to examine associations between ACEs and DEBs among middle-aged adults and examine sex differences. ACEs prior to age 18 were retrospectively assessed in the Coronary Artery Risk Development in Young Adults study in 2000-2001 (N = 3340, ages 32 to 46). DEB outcomes (i.e., concerns about weight and shape, anxiety about eating or food, unhealthy weight control behaviors, chronic dieting, overeating, and binge eating) were assessed in 1995-1996 (ages 27 to 41). Modified Poisson regressions estimated risk ratios (RRs) for associations of a history of any ACE, each ACE, and cumulative ACEs with DEB outcomes. Among women, emotional abuse, physical neglect, and emotional neglect were each modestly associated with most DEBs (RRs = 1.21-1.35, 1.21-1.45, and 1.23-1.41 across DEBs, respectively) after adjustment for sociodemographic variables, BMI, and depressive symptoms. A cumulative ACE score was associated with all DEBs in a stepwise manner (p for trend ≤0.05) except concerns about weight and shape and overeating. Among men, emotional abuse was most consistently related to the majority of DEBs (RRs = 1.23-1.92); household substance abuse was modestly associated with overeating (RR = 1.26, 95% CI = 1.04-1.53). ACEs were cumulatively associated with unhealthy weight control behaviors, overeating, and binge eating (p for trend <0.01).

RESUMEN

This cross-sectional study examines the association of childhood and adolescent/adult adversities with obesity across four racial/ethnic groups among emerging adult women aged 18 to 25 (n = 9310). Latent class analysis was used to identify racial/ethnicity-specific classes arising from childhood and adolescent/adult adversity indicators in the 2015 and 2018 College Student Health Surveys (sampled from Minnesota, U.S.) Distal outcome procedure and Bolck-Croon-Hagenaars methods were used to assess each class's association with body mass index (BMI) and obesity probability. Models were adjusted for post-secondary school type and parental education. We identified 7 classes for White women, 4 classes for Asian and Latina women, and 5 classes for Black women. Weight distributions of Black and Latina women leaned towards "overweight", whereas White and Asian women's BMI leaned towards "normal weight." Latina and Black women had a wider BMI range (~5 kg/m2) between classes with the highest versus lowest BMI than White and Asian women (~3 kg/m2), suggesting a stronger association between adversities and BMI. For Asian, Black, and White women, the "Low Adversities" class had the lowest obesity prevalence, while the "High Lifetime Adversities" class had the highest prevalence. In contrast, Latina women had the lowest obesity prevalence in the "High Adolescent/Adult Adversities & Low Childhood Adversities" class, and highest prevalence in the "Household Mental Illness" class. Results indicate that racial/ethnic disparities in obesity-related measures are reduced when racial/ethnic groups experience low adversity. Future research should explore tailored adversity interventions that consider adversity exposure differences across race/ethnicity as a strategy for reducing obesity risk.

RESUMEN

The COVID-19 pandemic has led to unemployment, school closures, movement restrictions, and social isolation, all of which are child abuse risk factors. Our objective was to estimate the effect of COVID-19 shelter in place (SIP) policies on child abuse as captured by Google searches. We applied a differences-in-differences design to estimate the effect of SIP on child abuse search volume. We linked state-level SIP policies to outcome data from the Google Health Trends Application Programming Interface. The outcome was searches for child abuse-related phrases as a scaled proportion of total searches for each state-week between December 31, 2017 and June 14, 2020. Between 914 and 1512 phrases were included for each abuse subdomain (physical, sexual, and emotional). Eight states and DC were excluded because of suppressed outcome data. Of the remaining states, 38 introduced a SIP policy between March 19, 2020 and April 7, 2020 and 4 states did not. The introduction of SIP generally led to no change, except for a slight reduction in child abuse search volume in weeks 8-10 post-SIP introduction, net of changes experienced by states that did not introduce SIP at the same time. We did not find strong evidence for an effect of SIP on child abuse searches. However, an increase in total search volume during the pandemic that may be differential between states with and without SIP policies could have biased these findings. Future work should examine the effect of SIP at the individual and population level using other data sources.

RESUMEN

Childhood maltreatment (abuse and neglect) is associated with a range of negative outcomes, but a gap remains in understanding of how specific maltreatment types, particularly neglect and non-familial sexual abuse, relate to health and behavior. This study examined the association of neglect and sexual abuse (both familial and non-familial), as well as familial physical and emotional abuse, with: depressive mood and eating disorders; tobacco and marijuana use; and BMI ≥ 25 kg/m2 and BMI ≥ 30 kg/m2 in young adults. Data came from Project EAT (Eating and Activity in Teens and Young Adults), a population-based longitudinal study of weight-related health from adolescence into young adulthood. Maltreatment before age 18 was retrospectively reported at ages 26-33. Risk differences (RDs) and 95% confidence intervals (CIs) were estimated for those with a given maltreatment type to those without, and also for the cumulative number of maltreatment types experienced. One in 3 participants reported abuse or neglect. All maltreatment types were associated with at least one adverse health outcome, with physical abuse being least consistently related to the outcomes. Emotional abuse showed the strongest association with depressive mood. All maltreatment types were associated with eating disorder diagnosis, tobacco use, and marijuana use (except physical abuse for eating disorder). There was little evidence of a maltreatment association with BMI ≥ 25 kg/m2; emotional abuse and neglect were associated with BMI ≥ 30 kg/m2. Prevention of maltreatment needs to be a top public health priority.

RESUMEN

Various types of stressors are associated with maladaptive eating, but how the stressor of everyday discrimination (e.g., less respect, poorer service) relates to maladaptive eating and adaptive eating remains unclear. We examined everyday discrimination as a predictor of maladaptive and adaptive eating. Data were collected in a population-based study, Eating and Activity over Time (N = 1410, ages 18-30). Everyday discrimination was categorized as none, low, moderate, or high. Outcomes included maladaptive eating (i.e., overeating and binge eating) and adaptive eating (i.e., intuitive eating and mindful eating). Modified Poisson regressions estimated the prevalence ratios (PRs) for overeating and binge eating associated with everyday discrimination. Linear regressions estimated associations between everyday discrimination and intuitive and mindful eating scores. After adjustment for age, ethnicity/race, gender, and socioeconomic status, moderate and high levels of discriminatory experiences were each associated with a significantly greater prevalence of binge eating (PR = 2.2, [95% CI = 1.3-3.7] and PR = 3.1, [95% CI = 2.0-4.7], respectively) and lower intuitive (ß = -0.4, [95% CI = -0.7, -0.2] and ß = -0.5 [95% CI = -0.8, -0.3], respectively), and mindful eating scores (ß = -0.3, [95% CI = -0.6, -0.1] and ß = -0.5 [95% CI = -0.8, -0.3], respectively) compared to young adults with no discriminatory experience. Public health efforts to prevent maladaptive eating and encourage the adoption of adaptive eating should consider the potential contribution of everyday discrimination and the need to advocate for equity and inclusion.

RESUMEN

Adverse experiences, such as childhood abuse and other violence victimization, are associated with problematic eating. However, whether different types of adversity relate to both maladaptive and adaptive eating behaviors is unclear. This study examined the associations of different adverse experiences with maladaptive (i.e., overeating and binge eating) and adaptive (i.e., intuitive eating and mindful eating) eating by gender. Data were derived from the EAT-2018 (Eating and Activity over Time) study (N = 1411, aged 18-30 years in 2017-2018). Modified Poisson regressions were used to examine the associations between adverse experiences and the prevalence of maladaptive eating. Linear regressions were used to examine the associations between adverse experiences and adaptive eating scores. Each adverse experience was associated with greater prevalence of maladaptive eating and lower adaptive eating scores. Among women, intimate partner sexual violence was strongly associated with more overeating (PR = 2.1 [95% CI = 1.4-3.1]) and binge eating (PR = 2.4 [95% CI = 1.5-3.9]), and less mindful eating (ß = -0.6, [95% CI = -0.8, -0.3]); being attacked, beaten, or mugged was most associated with less intuitive eating (ß = -0.5, [95% CI = -0.8, -0.2]). Among men, being attacked, beaten, or mugged was strongly associated with more overeating (PR = 2.1 [95% CI = 1.2-3.5]) and binge eating (PR = 3.2 [95% CI = 1.6-6.5]); intimate partner physical violence was strongly associated with less intuitive eating (ß = -0.6, [95% CI = -0.9, -0.2]); childhood emotional abuse was strongly associated with less mindful eating (ß = -0.8, [95% CI = -1.0, -0.5]). To improve eating behaviors, adverse life experiences and the potential impact on maladaptive and adaptive eating should be considered.

RESUMEN

BACKGROUND: The COVID-19 pandemic has created environments with increased risk factors for household violence, such as unemployment and financial uncertainty. At the same time, it led to the introduction of policies to mitigate financial uncertainty. Further, it hindered traditional measurements of household violence. OBJECTIVE: Using an infoveillance approach, our goal was to determine if there were excess Google searches related to exposure to child abuse, intimate partner violence (IPV), and child-witnessed IPV during the COVID-19 pandemic and if any excesses are temporally related to shelter-in-place and economic policies. METHODS: Data on relative search volume for each violence measure was extracted using the Google Health Trends application programming interface for each week from 2017 to 2020 for the United States. Using linear regression with restricted cubic splines, we analyzed data from 2017 to 2019 to characterize the seasonal variation shared across prepandemic years. Parameters from prepandemic years were used to predict the expected number of Google searches and 95% prediction intervals (PI) for each week in 2020. Weeks with searches above the upper bound of the PI are in excess of the model's prediction. RESULTS: Relative search volume for exposure to child abuse was greater than expected in 2020, with 19% (10/52) of the weeks falling above the upper bound of the PI. These excesses in searches began a month after the Pandemic Unemployment Compensation program ended. Relative search volume was also heightened in 2020 for child-witnessed IPV, with 33% (17/52) of the weeks falling above the upper bound of the PI. This increase occurred after the introduction of shelter-in-place policies. CONCLUSIONS: Social and financial disruptions, which are common consequences of major disasters such as the COVID-19 pandemic, may increase risks for child abuse and child-witnessed IPV.

RESUMEN

BACKGROUND: The Supplemental Nutrition Assistance Program (SNAP) is the largest anti-hunger program in the United States. Two proposed interventions to encourage healthier food expenditures among SNAP participants have generated significant debate: financial incentives for fruits and vegetables, and restrictions on foods high in added sugar. To date, however, no study has assessed the impact of these interventions on the benefit cycle, a pattern of rapid depletion of SNAP benefits that has been linked to worsening nutrition and health outcomes over the benefit month. METHODS: Low-income households not currently enrolled in SNAP (n = 249) received benefits every 4 weeks for 12 weeks on a study-specific benefit card. Households were randomized to one of four study arms: 1) incentive (30% incentive for fruits and vegetables purchased with study benefits), 2) restriction (not allowed to buy sugar-sweetened beverages, sweet baked goods, or candy using study benefits), 3) incentive plus restriction, or 4) control (no incentive or restriction). Weekly household food expenditures were evaluated using generalized estimating equations. RESULTS: Compared to the control group, financial incentives increased fruit and vegetable purchases, but only in the first 2 weeks after benefit disbursement. Restrictions decreased expenditures on foods high in added sugar throughout the benefit month, but the magnitude of the impact decreased as the month progressed. Notably, restrictions mitigated cyclical expenditures. CONCLUSIONS: Policies to improve nutrition outcomes among SNAP participants should consider including targeted interventions in the second half of the month to address the benefit cycle and attendant nutrition outcomes.

RESUMEN

The aim of this paper was to better understand how child and adult adversities cluster together into classes, and how these classes relate to body weight and obesity. Analyses included 2015 and 2018 data from emerging adults (18-25 years old) who participated in a state surveillance system of 2- and 4-year college students in Minnesota (N = 7475 in 2015 and N = 6683 in 2018). Latent Class Analyses (LCA) of 12 child and adult adversities were run stratified by gender and replicated between 2015 and 2018. The distal outcome procedure and three-step Bolck-Croon-Hagenaars approach were used to estimate predicted BMI means and predicted probabilities of obesity for each class, adjusted for covariates. The LCA identified seven classes in women and 5 in men. In women, BMI ranged from 23.9 kg/m2 in the lowest-BMI class ("Adult Adversities and Childhood Household Dysfunction"; 95% CI: 22.6-25.1) to 27.3 kg/m2 in the highest-BMI class ("High Lifetime Adversities"; 95% CI: 25.9-28.7), a statistically significant difference of 3.4 kg/m2. In men, the adjusted BMIs ranged from 24.6 kg/m2 ("Low Adversities"; 95% CI: 24.3-25.0) to 26.0 kg/m2 ("Childhood Household Mental Illness"; 95% CI: 25.1-26.9), a statistically significant difference of 1.4 kg/m2. The pattern was similar for obesity. These results indicate that specific classes of child and adult adversities are strongly associated with BMI and obesity, particularly in women. A key contribution of LCA appeared to be identification of small classes at high risk for excess weight.

RESUMEN

OBJECTIVE: Supplemental Nutrition Assistance Program (SNAP) benefits are rapidly depleted after distribution. This phenomenon, known as the benefit cycle, is associated with poor nutrition and health outcomes. However, to date, no study has evaluated trends in food expenditures before and after households receive benefits using prospective data, and whether these trends vary by household characteristics. DESIGN: Generalised estimating equations were used to model weekly household food expenditures during baseline (pre-benefit) and intervention months by vendor (restaurants and food retailers). Food retailer expenditures were further evaluated by food category (fruits and vegetables and foods high in added sugar). All expenditures were evaluated by household composition, demographics and economic means. SETTING: Minneapolis-St. Paul, Minnesota, metropolitan area. PARTICIPANTS: Low-income households (n 249) enrolled May 2013-August 2015. RESULTS: Weekly food retailer expenditures did not vary during baseline (pre-benefit), but demonstrated a cyclical pattern after households received benefits across all household characteristics and for both food categories, particularly for fruits and vegetables. Households with greater economic resources spent more throughout the month compared with those with fewer resources. Households with lower food security status experienced more severe fluctuations in spending compared with more food secure households. CONCLUSIONS: Cyclical food purchasing was observed broadly across different household characteristics and food categories, with notable differences by household economic means and food security status. Proposed SNAP policy changes designed to smooth food expenditures across the benefit month, such as increased frequency of benefit distribution, should include a focus on households with fewest resources.

RESUMEN

This study examined gender differences in the association between childhood maltreatment and disordered eating attitudes and behaviors in adulthood. Data were derived from 1647 adults (ages 27-33) participating in a population-based, longitudinal study (Project EAT-IV: Eating Among Teens and Young Adults, 1998-2016). Childhood maltreatment (sexual abuse, physical abuse, emotional abuse, emotional neglect) and disordered eating attitudes and behaviors (overeating, binge eating, extreme weight control behaviors, unhealthy weight control behaviors, chronic dieting, weight and shape concerns) were assessed. Relative risk regression models were used to examine whether childhood maltreatment was related to individual disordered eating attitudes and behaviors. Gender differences in these associations were explored. A history of any childhood maltreatment was associated with more than 60% greater risk for chronic dieting and overeating, with additional associations found for binge eating, weight and shape concerns, and unhealthy weight control behaviors. All types of abuse and neglect were associated with at least one type of disordered eating outcome. Examination of the point estimates indicated that emotional neglect was most consistently related to higher risk for disordered eating attitudes and behaviors. Although there were no statistically significant gender differences in the association between childhood maltreatment and disordered eating attitudes and behaviors, the patterning of these effects highlighted unique qualitative similarities and differences in these relationships between men and women. Taken together, these findings implicate childhood maltreatment, particularly emotional neglect, as a meaningful risk factor for problematic eating outcomes in both men and women during adulthood.

RESUMEN

Intuitive eating has been associated with markers of better health in cross-sectional studies, but less is known about long-term associations between intuitive eating and subsequent eating and weight-related behaviors. This study assessed how intuitive eating in early adulthood is related to weight status, dieting, healthy and unhealthy weight control behaviors, and binge eating with loss of control five years later. Young adults (N = 1660) were asked about intuitive eating as part of the 2008-2009 third wave of the Project EAT (Eating and Activity in Teens and Young Adults) longitudinal cohort study. Weight status, dieting, healthy and unhealthy weight control behaviors, and binge eating with loss of control were assessed during both the third (EAT-III: mean age 25.3 ± 1.5) and fourth (EAT-IV mean age 31.1 ± 1.5) waves. In analyses adjusted for sociodemographic characteristics, both male and female intuitive eaters had a lower prevalence of high weight status and lower engagement in dieting, unhealthy weight control behaviors, and binge eating at the 5-year follow-up, compared to non-intuitive eaters. Among women, after additional adjustment for EAT-III values for the respective outcome measures, intuitive eating was unrelated to any of the behaviors studied at 5-year follow-up. Among men, intuitive eating predicted a lower likelihood of engaging in unhealthy weight control behaviors (intuitive eaters: 30.0% vs. non-intuitive: 41.9%, p = 0.002) and binge eating (intuitive eaters: 0.9% vs. non-intuitive: 1.5%, p = 0.046) independent of participating in these behaviors at EAT-III. In a population-based sample of young adults, intuitive eating was associated with better markers of eating and weight-related behaviors five years later, suggesting intuitive eating may have potential long-term benefits.
