Late Luteal Subphase Food Craving Is Enhanced in Women with Obesity and Premenstrual Dysphoric Disorder (PMDD)

Dysregulated food craving is a complex weight-related behavior. To identify novel targets for enhancing the efficacy of weight loss interventions, we examined whether food craving varies across the menstrual cycle according to the abdominal obesity type and premenstrual dysphoric disorder (PMDD) diagnosis, and, if so, whether it is related to affective symptomatology. Reproductive-age women were classified into one of the four study groups according to whether they have abdominal obesity (AO) or are abdominally lean (AL), and the presence of PMDD: (1) AO:PMDD+ (n = 13), (2) AL:PMDD+ (n = 14), (3) AO:PMDD− (n = 15), and (4) AL:PMDD− (n = 16). Self-report measures as well as urinary luteinizing hormone (LH) tests were provided by the participants across 2–3 menstrual cycles. The ratings of food cravings were similar across the menstrual cycle, except the last, late luteal subphase as the AO:PMDD+ participants had the highest food craving rating. Irritability and depression were correlated with food cravings, but not in a distinctive manner across the menstrual cycle by group. Our study found that women with abdominal obesity and PMDD display a temporal vulnerability to a food-related behavior. The possibility of shared neurobiology between the two conditions is discussed and should be examined in future studies.

Effectiveness of NCD-Related Fiscal Policies: Evidence from the Pacific.

Obesity in Pacific Island countries (PICs) has hit crisis levels, and the consequent high non-communicable disease (NCD) burden is devastating for their developing economies. Nutrition transitions from traditional, plant and seafood diets to a dependence on processed foods are at the core of the obesity and NCD epidemic in PICs. Fiscal policies are widely promoted as an effective mechanism to reduce consumption of unhealthy foods and increase consumption of fruits and vegetables. However, there are little data to evaluate the effectiveness of these policies as rates of NCDs and obesity in PICs continue to rise. This study used an online survey to recruit 4116 adults from six PICs: Fiji, Kiribati, Samoa, Solomon Islands, Tonga and Vanuatu. The study measured the consumption of and household access to sugar-sweetened beverages, ultra-processed packaged snacks, fruits and vegetables and attitudes on food prices and unhealthy eating. The study also assessed the relationship between consumption of these foods and drink and (1) household access, (2) price as a food choice motive, and (3) unhealthy eating attitudes. This study provides novel data on food-related behaviours in PICs, offers insights into the potential impact of NCD-related fiscal policies on food consumption and identifies other variables of interest.

Call for emergency action to restore dietary diversity and protect global food systems in times of COVID-19 and beyond: Results from a cross-sectional study in 38 countries

BackgroundThe COVID-19 pandemic has revealed the fragility of the global food system, sending shockwaves across countries' societies and economy. This has presented formidable challenges to sustaining a healthy and resilient lifestyle. The objective of this study is to examine the food consumption patterns and assess diet diversity indicators, primarily focusing on the food consumption score (FCS), among households in 38 countries both before and during the first wave of the COVID-19 pandemic. MethodsA cross-sectional study with 37 207 participants (mean age: 36.70 ± 14.79, with 77 % women) was conducted in 38 countries through an online survey administered between April and June 2020. The study utilized a pre-tested food frequency questionnaire to explore food consumption patterns both before and during the COVID-19 periods. Additionally, the study computed Food Consumption Score (FCS) as a proxy indicator for assessing the dietary diversity of households. FindingsThis quantification of global, regional and national dietary diversity across 38 countries showed an increment in the consumption of all food groups but a drop in the intake of vegetables and in the dietary diversity. The household's food consumption scores indicating dietary diversity varied across regions. It decreased in the Middle East and North Africa (MENA) countries, including Lebanon (p < 0.001) and increased in the Gulf Cooperation Council countries including Bahrain (p = 0.003), Egypt (p < 0.001) and United Arab Emirates (p = 0.013). A decline in the household's dietary diversity was observed in Australia (p < 0.001), in South Africa including Uganda (p < 0.001), in Europe including Belgium (p < 0.001), Denmark (p = 0.002), Finland (p < 0.001) and Netherland (p = 0.027) and in South America including Ecuador (p < 0.001), Brazil (p < 0.001), Mexico (p < 0.0001) and Peru (p < 0.001). Middle and older ages [OR = 1.2; 95 % CI = [1.125–1.426] [OR = 2.5; 95 % CI = [1.951–3.064], being a woman [OR = 1.2; 95 % CI = [1.117–1.367], having a high education (p < 0.001), and showing amelioration in food-related behaviors [OR = 1.4; 95 % CI = [1.292–1.709] were all linked to having a higher dietary diversity. ConclusionThe minor to moderate changes in food consumption patterns observed across the 38 countries within relatively short time frames could become lasting, leading to a significant and prolonged reduction in dietary diversity, as demonstrated by our findings.

Financial satisfaction, food security, and shared meals are foundations of happiness among older persons in Thailand

The objective of this study was to investigate the association between happiness and food-related behaviours and other potential factors among older persons in Thailand. This was a cross-sectional study with multistage random sampling. In total, 1,197 older (age 60 + years) persons participated in this study. Face-to-face interviews were conducted to obtain information about socio-demographic characteristics, health status, household chores, home gardening, financial situation, family meals, and food security. Descriptive and multivariate regression analyses were performed for data analysis. The analysis found that age, health status, household chores, and home gardening were found to be significantly associated with happiness. Statistically-significant associations of financial situation, family meals, and food insecurity with happiness were also observed. People who were not dissatisfied with their financial situation were happier than people who were unhappy with their financial situation. Older people who ate every meal with a family member(s) were happiest. People who had severe food insecurity were less happy than those with food security. The findings suggest the need for investment priorities on food and nutrition with a long-term policy to ensure financial self-sufficiency and food security among older persons and their family.

Portion size affects food selection in an immersive virtual reality buffet and is related to measured intake in laboratory meals varying in portion size

A crucial step for validating the utility of an immersive virtual reality (iVR) buffet to study eating behavior is to determine whether variations in food characteristics such as portion size (PS) are relevant predictors of food selection in an iVR buffet. We tested whether manipulating PS in an iVR buffet affects the weight of food selected, and whether this response to PS is similar to participants' measured intake when PS varies at laboratory meals. In a randomized crossover design, 91 adults (18-71 y; 64 females; BMI = 25.3 ± 5.7) used their iVR remote to select lunch and dinner portions from an iVR buffet before consuming a standardized lab meal at two visits separated by one week. The PS in the iVR buffet and lab meals varied between a standard PS and a large PS. This design enabled comparisons of PS effects between iVR and lab settings, despite the scale difference in food weight between the environments. Portion size significantly affected food selection and food intake (p < 0.001). Subjects selected an additional 350 g in iVR and consumed an additional 154 g of food in the lab meals when offered the large portion compared to the small portion. The effect of PS showed a similar percentage increase in iVR (36.5%) and lab meals (39.2%). There was no significant difference in the effect of PS between iVR and lab meals after accounting for scale differences in food weight between the environments. The response to PS was not influenced by subject characteristics such as body mass index, sex, or age. These results demonstrate the utility of iVR for replicating real-world eating behaviors and enhancing our understanding of the intricate dynamics of food-related behaviors in a variety of contexts.

Predicting food waste in households with children: socio-economic and food-related behavior factors.

The consumption phase accounts for approximately half of the food waste generated within the food system. Numerous studies have identified families with children as the primary contributors to food waste. The aims of this paper is to enhance the comprehension of food waste behaviors in households with children by characterizing it and studying how socioeconomic characteristics and food-related behaviors can predict it. A survey was conducted among 806 families with children, categorized by the child's age and family structure. The study utilized descriptive statistics to summarize the food waste behaviors and binary regression to evaluate the predictive abilities of 12 variable related to the socio-economic characteristic, purchase, and preparation behaviors and diet quality factors. Perishable food items, such as fruits, vegetables, cereal-based product, and dairy products, were the primary items wasted in households with children. Two patterns of food waste were identified: inadequate food management leading to small amounts of waste in families with young and middle-aged children, and over-purchasing perishable items leading to waste in other households with children. Household type and purchasing habits were significant predictors, while the purchaser's age and buying channel showed lower predictive capacity. Policies to reduce food waste should prioritize raising awareness among children, promoting good practices at the household level, and creating favorable conditions during purchases. Strategies include enlisting children's participation in meal planning and food preparation as well as limiting the promotion of ultra-processed products and incentivizing the sale of bulk products at supermarket.

Intergenerational differences in healthy eating beliefs among British Pakistanis with type 2 diabetes.

There are growing concerns on how to prevent, slow down and induce remission of type 2 diabetes mellitus (T2DM). Recent evidence has found diet and lifestyle interventions can cause remission of T2DM, however, there are challenges for diverse groups such as British Pakistanis who are four times more at risk of T2DM. There is a need to understand the food behaviours of different generational groups to develop culturally appropriate strategies to support diabetes prevention programmes. This study explores beliefs about healthy eating and food practices related to T2DM among British Pakistanis to understand the challenges they face in implementing healthy diets. We carried out 26 semi-structured qualitative interviews via telephone and face-to-face. The sample included T2DM British Pakistanis living in Bradford (UK), aged between 18 and 71 with a mean age of 50 (SD = 17.04). Among the participants, 14 were women (54%) and 12 were men (46%), with interviews conducted in both English (76%) and Urdu (24%). Participants were grouped under three generation groups based on age (first generation 65+; second generation 40-64; younger generation 18-39 years). There was no biological link between the generational groups, and they were not part of the same family. Data were analysed using qualitative reflexive thematic analysis. Findings were categorised into three themes: knowledge and awareness of diabetes symptoms; social and family context of food practices and making sense of healthy eating. The family was the fundamental unit of understanding food-related health behaviours. Eating traditional food was perceived as healthy and deemed practical for first generations who were the initial members of their family to settle in the UK as well as the second generations who had parents born in Pakistan. Younger British Pakistanis were born in the UK and reported that they struggled to eat alternative foods within the home and manage their T2DM. These findings improve our understanding of how three generations of British Pakistanis with T2DM negotiate healthy diets. There is a need for culturally tailored diet modifications and interventions, where different generational needs can be specifically targeted to adopt healthier diets which should be shared and encouraged.

Food-related consumer behaviours in times of crisis: Changes in the wake of the Ukraine war, rising prices and the aftermath of the COVID-19 pandemic

When the COVID-19 pandemic subsided, the war in Ukraine led to further disruptions in consumers’ daily behaviours, with rising prices for food and energy. We conducted a survey study on self-reported changes in food-related consumer behaviour in ten European countries and compared the results to a similar study conducted two years ago. A latent class cluster analysis distinguished five clusters and showed that different types of consumers can be distinguished based on how they react to the crisis as regards their eating habits. 19% of survey participants reported no major changes, and 32% reported changes mostly in terms of more price sensitivity. Among those that reported changes beyond reacting to higher prices, there are indications of more mindful eating and more deliberate choices. The changes already found earlier in response to the COVID-19 pandemic therefore seem to have been strengthened and supplemented by reactions to price increases. The results present a challenge to the food industry in terms of supplying healthy and sustainable food at affordable prices.

Impact of COVID-19 on food behavior and diet in Qatar: A cross-sectional survey on the Omicron variant.

The emergence of the Omicron variant in November 2021 appears to have impacted food-related activities and behaviors and caused disruptions in food supply systems. Accordingly, this article aims to explore the effects of the Omicron variant on consumers' food-related behaviors in Qatar. This research is based on an online survey performed in Qatar in December 2021 and January 2022. The survey consisted of 23 questions arranged into three sections, including both multiple-choice and one-option items. There were 459 valid responses in total. The Omicron variant has altered diets and food shopping in Qatar. Indeed, the findings indicated (i) consumers in Qatar are shopping less often and purchasing more each trip; (ii) an increase in food online shopping; (iii) an increase in the use of online applications to buy ready-made food; and (iv) an increase in the consumption of healthy foods, especially immunity-boosting ones. Furthermore, consumers' awareness and general understanding regarding the virus, its transmission, food safety risks, etc., have evolved. On the one hand, consumers take precautionary measures to protect themselves. On the other hand, they are learning to live with the virus. This research, along with subsequent ones, will provide the foundation for institutional and governmental readiness in the face of potential shocks, crises, and pandemics. The repercussions of the ongoing conflict in Ukraine on food systems throughout the globe (cf. food prices increase) imply that it's a crucial and pressing issue that needs immediate attention.

The FLY-project: study protocol for mixed methods research to explore the complex social dynamics of sustainable food-related lifestyles in youth in practical education

BackgroundThe present-day food system is a key driver of climate change and biodiversity loss, making it imperative for populations to shift towards more sustainable diets. The involvement of youth in this transition is vital because they are in a formative period where their identities, values, and norms, including their food behaviours, are being shaped. Special attention should be paid to youth in practical education because they are often overlooked in existing studies, yet evidence suggests they may lack the necessary resources to support dietary changes, resulting in lower levels of pro-environmental food-related behaviours. The aim of the FLY (Food-related Lifestyles in Youth) project is to study how sustainable food-related lifestyles and underlying factors develop in early adolescence, particularly in Dutch youth in practical education, how these spread in social networks, and to develop community-level intervention strategies to support youths’ transition to sustainable food-related behaviours.Methods/designThe FLY-project adopts a mixed-method approach. First, two literature reviews are conducted. A systematic review assesses how capabilities, opportunities and motivation are associated with sustainable food behaviours in youth, and how these elements interrelate in determining sustainable food-related lifestyles. A scoping review studies community-level interventions that target sustainable and healthy food-related behaviours. Second, focus groups are conducted to explore the barriers and facilitating factors concerning capabilities, opportunities, and motivations that Dutch youth in practical-level education experience to transition to more sustainable food-related lifestyles. Third, a cohort survey study is conducted to track the dynamic interplay between capabilities, opportunities, motivation, and changes in specific sustainable food behaviours over time, and to assess the diffusion of sustainable food-related lifestyles via social (media) networks. Fourth, an experimental research programme tests promising intervention approaches, some of which are co-created with youth, targeting relevant underlying factors.DiscussionThis paper describes the rationale, conceptual framework, design and methods of the FLY-project. The FLY-project contributes to an understanding of underlying factors of sustainable food-related behaviours in adolescence and results in a multi-component intervention toolkit, with a particular focus on youth in practical education programmes.

Does this virtual food make me hungry? effects of visual quality and food type in virtual reality

Introduction: Studies into food-related behaviors and emotions are increasingly being explored with Virtual Reality (VR). Applications of VR technologies for food science include eating disorder therapies, eating behavior studies and sensory analyzes. These applications involve 3D food stimuli intended to elicit cravings, stress, and/or emotions. However, the visual quality (i.e., the realism) of used food stimuli is heterogeneous, and this factor’s influence on the results has never been isolated and evaluated. In this context, this work aims to study how the visual quality of food stimuli, exposed in a virtual reality environment, influences the resulting desire to eat.Methods: 28 subjects without eating disorders were included in this protocol, who evaluated the desire to eat induced by 10 3D food stimuli, each duplicated in 7 quality levels (for a total of 70 stimuli).Results: Results show that visual quality influences the desire to eat, and this effect depends on the type of food and users’ eating habits. We found two significant thresholds for visual quality: the first provides the minimal quality necessary to elicit a significant desire to eat, while the second provides the ceiling value above which increasing the quality does not improve further the desire to eat.Discussion: These results allow us to provide useful recommendations for the design of experiments involving food stimuli.

Impact of COVID-19 on the Lifestyle of Students of Taibah University, Madinah.

Background The coronavirus disease 2019 (COVID-19) lockdown affected the daily habits of people around the world. Many countries have contributed to restricting its transmission by ensuing a quarantine, including Saudi Arabia, by shutting down educational facilities. Therefore, the system adapted to those changes, and people were required to stay home for work and education. Objectives This study aimed to explore the effect of the lockdown and house confinement during the COVID-19pandemic on the important aspects of lifestyle, such as body weight, dietary habits, sleeping patterns, stress levels, screen time, and physical activity among students of Taibah University in Madinah, Saudi Arabia. Methods A cross-sectional study was carried out by a self-administered online questionnaire that was quoted from a Palestinian study. Thenwas translated from English to Arabic. In total, 528 Taibah University students were eligible to participate. It addressed food-related behavior (types of foods consumed) and lifestyle behavior (physical activity, sleep quality, and screen time). Results Study participants aged from 17 to 30 years, males and females. Mainly non-infected COVID-19 persons previously (54.4%). Participants showed an increase in body weight, intake of fried food, intake of sweets, sleep hours, screen time, and physical activity during lockdown. The most reported sources of stress during lockdown were staying at home all day (62.3%) and distance learning (44.9%). Conclusion The COVID-19 lockdown and the closure of universities have led to many changes in the everyday routine of university students, leading to changes in their lifestyle behaviors.

Evaluation of Recipes for Life Nutrition Education Program for Fifth-Grade Students

Emerging research indicates that chronic illnesses exacerbated by obesity begin in childhood. While research continues to show that consumption of fruits and vegetables can lower rates of obesity, children in the United States often fall short of consuming the recommended daily intake of fruits and vegetables. Youth nutrition education and cooking education programs have emerged as proven strategies for promoting youth consumption of fruit and vegetables, and other factors (e.g., nutrition knowledge, food-related behaviors, food preferences, attitude toward cooking, and cooking self-efficacy) that mediate youth consumption of fruits and vegetables. The purpose of this study was to evaluate the impact of the Recipes for Life program, a field-trip-based nutrition education program, on fifth-grade students. Results showed that the program elicited pre-post improvements in students’ content knowledge, cooking self-efficacy, and cooking attitudes.

Effect of time restricted feeding on anthropometric measures, eating behavior, stress, serum levels of BDNF and LBP in overweight/obese women with food addiction: a randomized clinical trial

ABSTRACT Background & aim Food addiction (FA) as a specific food-related behavior may play an essential role in the pathogenesis of obesity. Brain-derived neurotrophic factor (BDNF) and gut microbiota (GM) alterations probably through fasting are closely related to brain function, affecting eating behaviors and body weight management. This study aimed to evaluate the effect of time-restricted feeding (TRF) on serum BDNF levels and eating behaviors in overweight and obese women with FA. Methods and design This clinical trial was performed with a 2-month follow-up on 56 obese and overweight women with FA. Participants were randomly divided into two groups receiving a low-calorie diet (n = 27) and a group receiving a low-calorie diet with TRF (n = 29). Anthropometric measurements, biochemical markers, eating behavior, and stress were assessed during the study period. Results The reductions in weight, body mass index (BMI), waist circumference, and body fat mass were significantly higher in the TRF group compared to the control group at week 8 (P = 0.018, P = 0.015. P = 0.03, and P = 0.036, respectively). The cognitive restriction score was higher in the TRF as compared with the control group (P = 0.002). The food addiction criteria score was significantly reduced in both groups (P < 0.001). Serum levels of BDNF were significantly increased in the TRF group (P < 0.001). In addition, BDNF levels had a positive and significant correlation with the cognitive restriction score (r = 0.468 and P < 0.001), While the correlation with FA was not significant (β = 0.588 and P = 0.618). Lipopolysaccharide binding protein decreased significantly in both groups, but this decrease was significantly higher in the TRF group than in the control group (P < 0.001). Conclusion The results of this study showed that a low-calorie diet with TRF is more effective in weight management than a low-calorie diet alone, probably through further modulating the GM and improving BDNF levels. More effective weight loss in the TRF is probably related to better management of eating behavior than FA. Trial registration Iranian Registry of Clinical Trials identifier: IRCT20131228015968N7.

The Integrated Effect of Environmental Conditions and Human Presence on the Behaviour of a Pair of Zoo-Housed Asian Small-Clawed Otters

Zoos and aquaria have the ethical responsibility to provide animals under their care with conditions that promote good welfare. This study evaluated the combined influence of human presence and environmental factors on the behaviour of zoo-housed Asian small-clawed otters (Aonyx cinereus). Data collection was conducted on a pair hosted at Pistoia Zoo (Italy). Data were collected from July to September 2020 (over 14 days). We video-recorded the otters’ behaviours, using the continuous focal animal sampling, obtaining 42 h of observation per subject. The otters displayed a wide array of species-specific behaviours. Compared to previous captive studies, the subjects engaged less in locomotion, food-related and affiliative behaviours, and more in vigilance. Human–animal interactions were limited, and mostly elicited neutral or positive responses, except for begging behaviours performed towards caregivers. Time of day and animal identity were the main significant predictors for behaviours. No effects of visitor presence or background noise were detected. Nonetheless, increasing enrichment use could stimulate food-related behaviours, and reduce vigilance and begging. This study confirms the importance of applying an integrated approach to analyse the complexity of otters’ experiences, and provides insights to guide husbandry improvements.

Urban Agriculture in Great Bandung Region in the Midst of Commercialization, Food Insecurity, and Nutrition Inadequacy

The proliferation of commercialization in the development of urban agriculture (UA) within the Great Bandung region has precipitated the dislocation of numerous small-scale farmers, consequently engendering a reduction in the accessibility of locally cultivated sustenance. The resultant effect of this phenomenon is the exacerbation of food insecurity among low-income inhabitants who lack the financial wherewithal to procure the relatively expensive imported food items. Furthermore, the dearth of availability of unprocessed, high-quality sustenance has resulted in suboptimal dietary intake among a considerable proportion of the populace. A survey was conducted utilizing questionnaires to gather data from 137 units of respondents consisting of both subsistence and commercial urban farmers. The comparative analysis of the earnings of urban farmers was conducted vis-à-vis the minimum wages projected for the year 2023 in West Java and Bandung City. The utilization of the Food Insecurity Experience Scale (FIES) is a prevalent method for evaluating food insecurity through the analysis of self-reported food-related behaviors and experiences, both pre- and post-UA operations. A 24 h Food Recall Instrument examined nutrition adequacy in urban farmer households, which was analyzed using chi-square with descriptive presentation. Urban agriculture could help solve commercialization, food insecurity, and nutrition issues in the Great Bandung Region. Commercial urban farmers (51.09%) earned 280.46% of West Java provincial minimum wages or 136.82% of Bandung City minimum wages in 2023. The subsistence farmers’ cohort (48.91%) earned 14.64% of West Java provincial minimum earnings or 7.14% of Bandung City minimum wages in 2023. In general, the prevalence of ties to food insecurity was predominantly observed subsequent to UA practices. The study revealed a prevalence of vitamin A surplus among urban farmers, while a preponderance of inadequacy in other nutritional aspects was also observed.

Prefrontal cortex melanocortin 4 receptors (MC4R) mediate food intake behavior in male mice

BackgroundMelanocortin 4 receptor (MC4R) activity in the hypothalamus is crucial for regulation of metabolism and food intake. The peptide ligands for the MC4R are associated with feeding, energy expenditure, and also with complex behaviors that orchestrate energy intake and expenditure, but the downstream neuroanatomical and neurochemical targets associated with these behaviors are elusive. In addition to strong expression in the hypothalamus, the MC4R is highly expressed in the medial prefrontal cortex, a region involved in executive function and decision-making. MethodsUsing viral techniques in genetically modified male mice combined with molecular techniques, we identify and define the effects on feeding behavior of a novel population of MC4R expressing neurons in the infralimbic (IL) region of the cortex. ResultsHere, we describe a novel population of MC4R-expressing neurons in the IL of the mouse prefrontal cortex that are glutamatergic, receive input from melanocortinergic neurons, and project to multiple regions that coordinate appetitive responses to food-related stimuli. The neurons are stimulated by application of MC4R-specific peptidergic agonist, THIQ. Deletion of MC4R from the IL neurons causes increased food intake and body weight gain and impaired executive function in simple food-related behavior tasks. ConclusionTogether, these data suggest that MC4R neurons of the IL play a critical role in the regulation of food intake in male mice.

Body mass index variation in adults with Williams syndrome: associations with predicted dietary intake and food behaviors.

Dietary intake and body weight are important predictors of long-term health. However, few studies have focused on these topics in adults with genetic syndromes that have associated intellectual disability, such as Williams syndrome (WS). In adults with WS, describe predicted dietary intake, food-related problems, and associations between body mass index (BMI) and possible factors contributing to differences in weight status. In this study of 82 participants (median age of 30 years, range 18-69), we cross sectionally investigated associations between BMI, predicted dietary intakes (Dietary Screener Questionnaire), food-related behaviors (Food-Related Problem Questionnaire), and anxiety (Spence Children's Anxiety Scale). Longitudinal patterns of weight change were further studied in a subset (n = 41). BMI variation was observed with median BMI of 27.3 kg/m2 (range 16.7-55.5 kg/m2). Several components of dietary intake deviated from recommendations in the WS cohort. When compared with WS participants with either normal or overweight BMI, WS participants with obesity had reduced daily intake of fruits and vegetables of 0.15 cup equivalents (P = 0.049), while participants with underweight BMI had reduced daily intake of fruits and vegetables of 0.44 cup equivalents (P = 0.026) and additionally had reduced intake of dietary fiber of 2.12 grams per day (P = 0.019). A one-point increase in the 'preoccupation with food' sub-score was associated with a 0.57 unit increase in BMI (P = 0.16), while a one-point increase in the 'takes and stores food' sub-score was associated with a 0.72 unit increase in BMI. In the longitudinal weight subset, a weight gain group and a weight stable group were identified. The former was associated with increased 'takes and stores food' sub-score but not with dietary intakes. We observed considerable BMI variability. While few dietary intakes were associated with BMI, increased BMI and weight gain were associated with 'preoccupation with food' and with 'takes and stores food' behavior sub-scores.
