To complement literature-based historical knowledge of the eating habits of 17th- and 18th-century Japan, we analysed carbon and nitrogen isotope ratios (δ<sup>13</sup>C and δ<sup>15</sup>N, respectively) of human hairs embedded in cover paper of Japanese books printed during 1690s-1890s, taking regional and temporal variations into consideration. We purchased 24 book sets from second-hand book markets. Twenty-three sets contained enough human hairs, which were non-destructively extracted from t ...[more]

Project description:ObjectivesThe rapid increase in Chinese obesity rates has aroused research interest in addiction-like eating (AE); however, the unavailability of assessment tools is a major barrier to further investigation. To address the research gap, this study aimed to evaluate the psychometric properties of the Addiction-like Eating Behavior Scale (AEBS) and explore associations between AE and three modern eating-related habits (i.e., ordering delivery food, eating late-night meals and watching mukbang) among Chinese adults.MethodsThe STROBE checklist was followed for reporting this cross-sectional study. We conducted a telephone survey with a two-stage cluster random sampling method and acquired a probability sample of 1010 community-dwelling Chinese adults (55.2% female; age: 18-88 years, M = 38.52, SD = 14.53).ResultsResults confirmed the conceptualized two-factor structure of AEBS with satisfactory model fit, reliability and validity. Chinese adults reported higher levels of AE in the context of low dietary control rather than appetitive drive. These two AE factors showed significant and positive associations with modern eating-related habits.ConclusionsThe current study was the first to assess AE among Chinese adults and provided a reliable and valid assessment tool. Our correlational findings can also be utilized for designing interventions for weight management and healthy eating.

Project description:BACKGROUND:Disordered eating, ranging from occasional binge eating or restriction to behaviors associated with eating disorder diagnoses, is common among military personnel and veterans. However, there is little information on how military service affects eating habits. OBJECTIVE:To describe possible pathways between military service and disordered eating among women veterans, a high risk group. MATERIALS AND METHODS:Twenty women veterans who reported changing eating habits in response to stress participated in audio-recorded focus groups or dyadic interviews between April 2013 and October 2014. We used thematic analysis of transcripts to identify and understand women's self-reported eating habits before, during, and after military service. RESULTS:Participants reported entering the military with varied eating habits, but little disordered eating. Participants described several ways military environments affected eating habits, for example, by promoting fast, irregular, binge-like eating and disrupting the reward value of food. Participants believed military-related stressors, which were often related to gender, also affected eating habits. Such stressors included military sexual trauma and the need to meet military weight requirements in general and after giving birth. Participants also reported that poor eating habits continued after military service, often because they remained under stress. CONCLUSIONS:For some women, military service can result in socialization to poor eating habits, which when combined with exposure to stressors can lead to disordered eating. Additional research is needed, including work to understand possible benefits associated with providing support in relation to military weight requirements and the transition out of military service. Given the unique experiences of women in the military, future work could also focus on health services surrounding pregnancy-related weight change and the stress associated with being a woman in predominantly male military environments.

Project description:There has been an increasing interest in low fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) diets for irritable bowel syndrome. The aims of the present study were (1) to survey knowledge and eating habits with respect to low- and high-FODMAP foods in a general population, and (2) to analyze the relationship between lower gastrointestinal problems (LGIP, pain and irregular stool habits) and habits/foods for prevention. The present study was carried out with medical examinees (n = 1024) at a clinic in Japan using self-administrated questionnaires. The subjects were asked whether they knew each FODMAP food, eating habit, and cooking habit. Chi-squared tests were used for analyzing the characteristics of LGIP-related factors. Logistic regression models were utilized to select foods which predict LGIP. Women cooking by themselves and who were younger indicated less LGIP (Chai-square for trend). More than 60% reported that they often ate rice, coffee, eggs, pork, chicken, breads, noodles, and onions, which are solely classified as high-FODMAP foods. LGIP was related to age and self-cooking habits in women. Soybeans had the least significant relationship with LGIP (odds ratio (OR) 0.48, 95% confidence interval (CI) 0.32-0.73), followed by seaweed, shellfish, wheat, cow's milk, green beans, and cauliflower. In contrast, artificial sweeteners were most significantly related with LGIP (OR 1.54, 95% CI 1.16-2.03), followed by margarine and tomato paste. The associations between FODMAP foods and LGPI appeared to be different from the Western results. Furthermore, some diets related to LGIP are suggested.

Project description:Mothers who underwent bariatric surgery (BS) before pregnancy have worrisome eating habits, but little is known about the eating habits of their offspring. EFFECTOR is a cross-sectional, long-term follow-up study of 4-11-year-old children born from mothers that underwent bariatric surgery before pregnancy (n = 36), mothers with overweight/obesity (OW/OB) in a control group (n = 71), and mothers with a normal weight (NW) in a second control group (n = 35). Data on anthropometry and on eating habits obtained through a Food Frequency Questionnaire were collected prospectively. The children's body mass index (BMI) scores significantly correlated with maternal pre-pregnancy BMI. The prevalence of overweight and obesity was the highest in children of the BS group (38.9% vs. 15.5% for children of the OW/OB group and 5.7% for those of the NW group; p = 0.004). Meal-skipping behavior was comparable between the groups. There was no difference in fruit and vegetable consumption. The BS group consumed more low-calorie sweetened beverages compared to the NW group (p = 0.01) but less fruit juice compared to the NW and OW/OB groups (p = 0.01). Our results may indicate a sugar-avoiding behavior in children of the BS group, fitting dietary maternal habits in a strategy to prevent dumping syndrome. In conclusion, maternal pre-pregnancy bariatric surgery does not alter unhealthy eating behaviors and the risk of development of overweight during childhood in their children.

Project description:Background Recent quantitative studies have illuminated dietary- and lifestyle-related changes that students experienced during global coronavirus lockdowns. Limited qualitative research on the US undergraduate student population has been published on this topic. Objective The study aimed to describe eating-related behavior changes reported by US undergraduate students during the COVID-19 pandemic. As a secondary aim, this study described behavior changes among students who were and were not Eating Competent (EC). Study Design, Setting, Participants This was a secondary analysis of data collected from an online survey administered from October through December 2020 to students at a major northwestern public university. The original survey consisted of previously validated and/or published instruments, including the Satter Eating Competence Inventory (ecSI 2.0™). Using a direct content analysis approach, this study coded respondents’ answers to the open-ended question “In what ways have your eating habits changed since the US coronavirus outbreak?” Measurable Outcome/Analysis Codes were written and classified under the four dimensions of Eating Competence: Eating Attitudes, Food Acceptance, Internal Regulation, and Contextual Skills. Other codes were developed to represent responses that did not fit within these dimensions. Respondents were categorized as EC or not EC based on their ecSI 2.0™scores. Results Responses from 1,529 participants were analyzed. Preliminary findings indicate that EC university students more frequently reported behavior changes like eating more fruits and vegetables and more home-cooked meals than non-EC students. Non-EC students more often reported eating more takeout, more processed foods, and more sugar compared to EC students. Mental-health-related changes, eating less regularly, disordered eating, and weight concerns were more commonly reported by non-EC students. Conclusions Compared to non-EC students, EC students reported more health-promoting behavior changes during the pandemic. This study highlights the potential benefit of teaching EC-related strategies to the US undergraduate student population and further elucidates behavior changes among students during the COVID-19 pandemic.

Project description:Background: COVID-19 virus has been reported as a pandemic in March 2020 by the WHO. Having a balanced and healthy diet routine can help boost the immune system, which is essential in fighting viruses. Public Health officials enforced lockdown for residents resulting in dietary habits change to combat sudden changes. Design and Methods: A cross-sectional study was conducted through an online survey to describe the impact of the COVID-19 pandemic on the eating habits, quality and quantity of food intake among adults in Saudi Arabia. SPSS version 24 was used to analyze the data. Comparison between general dietary habits before and during COVID-19 for ordinal variables was performed by Wilcoxon Signed Rank test, while McNemar test was performed for nominal variables. The paired samples t-test was used to compare the total scores for food quality and quantity before and during COVID-19 periods. Results: 2706 adults residing in Riyadh completed the survey. The majority (85.6%) of the respondents reported eating homecooked meals on a daily basis during COVID-19 as compared to 35.6% before (p<0.001). The mean score for the quality of food intake was slightly higher (p=0.002) before the COVID-19 period (16.46±2.84) as compared to the during period (16.39±2.79). The quantity of food mean score was higher (p<0.001) during the COVID-19 period (15.70±2.66) as compared to the before period (14.62±2.71). Conclusion: Dietary habits have changed significantly during the COVID-19 pandemic among Riyadh residents. Although some good habits increased, the quality and the quantity of the food was compromised. Public Health officials must focus on increased awareness on healthy eating during pandemics to avoid negative consequences. Future research is recommended to better understand the change in dietary habits during pandemics using a detailed food frequency questionnaire. Significance for public health Since pandemics come unannounced affecting public’s safety, it is important to understand the changes that occur in a community. This study focuses on the dietary habits’ changes during the COVID-19 pandemic. Coronavirus has been a threatening matter on a global level. It is tremendously crucial to consider various aspects of human health during pandemics including dietary habits, food quality and quantity as such factors play an important role in improving the immune system and overall health. Increasing the community’s awareness on the importance of healthy food intake during COVID-19 pandemic is extremely necessary. Public health’s role is to understand people’s reactions during pandemics and establish guidelines to improve health and prevent diseases. Dietary habits change during COVID-19 is a major health threat that needs immediate Public Health Officials’ attention. Maximizing awareness about healthy eating habits during quarantine requires attention to improve the overall health of the population.

Project description:Cardiovascular disease is the leading cause of on-duty mortality among firefighters, with obesity as an important risk factor. However, little is known regarding the dietary patterns which are characteristic in this population and how these patterns relate to cardiometabolic outcomes. The aim of this study was to identify the dietary patterns of US firefighters and examine their association with cardiometabolic outcomes. The participants (n = 413) were from the Indianapolis Fire Department, and were recruited for a Federal Emergency Management Agency (FEMA)-sponsored Mediterranean diet intervention study. All of the participants underwent physical and medical examinations, routine laboratory tests, resting electrocardiograms, and maximal treadmill exercise testing. A comprehensive food frequency questionnaire was administered, and dietary patterns were derived using principal component analysis. The mean body mass index (BMI) was 30.0 ± 4.5 kg/m2 and the percentage of body fat was 28.1 ± 6.6%. Using principal component analysis, two dietary patterns were identified, namely a Mediterranean diet and a Standard American diet. Following the adjustment for gender, BMI, maximal oxygen consumption (VO2 max), max metabolic equivalents (METS), age, and body fat percent, the Mediterranean diet was positively associated with high-density lipoprotein (HDL) cholesterol (β = 1.20, p = 0.036) in linear regression models. The Standard American diet was associated with an increase in low-density lipoprotein (LDL) cholesterol (β = -3.76, p = 0.022). In conclusion, the Mediterranean diet was associated with more favorable cardiometabolic profiles, whereas the Standard American diet had an inverse association. These findings could help in providing adequate nutrition recommendations for US firefighters to improve their health.

Project description:Traditionally, breakfast skipping (BS), and recently late-night dinner eating (LNDE), have attracted attention in public health because they can predispose to cardiometabolic conditions such as obesity and type 2 diabetes. Intriguingly, it has become evident that short duration of sleep elicits similar health risks. As LNDE, BS, and short sleep can be closely related and can aggravate each other, these three should not be considered separately. In this context, LNDE (or its equivalents, snacking or heavy alcohol consumption after dinner) and BS may be representative unhealthy eating habits around sleep (UEHAS). While it is important to take energy in the early morning for physical and intellectual activities, attaining a fasting state is essential for metabolic homeostasis. Our previous UEHAS studies have shown that BS without LNDE, i.e., BS alone, is not associated with obesity and diabetes, suggesting the possibility that BS or taking a very low energy breakfast, which could yield fasting for a while, may prevent obesity and diabetes in people with inevitable LNDE. Further studies considering UEHAS and short sleep simultaneously are needed to elucidate the effects of these unhealthy lifestyles on cardiometabolic diseases.

Project description:BackgroundA gap has been reported between healthcare professionals' (hereafter "professionals") recognition of preschool children's diets and parents' perception of concern. This study investigated the gap between the concerns reported by professionals and parents' perceptions regarding health and dietary habits by age (18 months and 3 years) and gender in Japan.MethodsThe study design consisted of a cross-sectional, multilevel survey. The request letters were sent to all households with target children with the cooperation of local governments. After obtaining written informed consent from parents, questionnaires were distributed to them. The survey included 30 items on children's concerns about health and dietary habits. At the health checkup, parents indicated whether they were concerned in response to each item, and responded child's height and weight and birth height and weight. Next, the professionals provided counseling to the parents at a health checkup. After that, the professionals noted their concerns in response to the same 30 items as those given to parents. The participation rates were 82.9% (18 months) and 82.8% (3 years). Data of 239 persons for 18 months and 223 persons for 3 years old were analyzed. In the statistical analysis, the items that were judged as concerning by professionals but not by parents were identified; likewise, the items that were of concern to parents but not to professionals were identified. Sensitivity, false negative rate, specificity, false positive rate, and Youden index were calculated to analyze the discordance rate for each item.ResultsMany parents in this study were concerned about the issues that professionals did not consider to be concerning. Moreover, the parents worried about more issues for 3-year-olds than for 18-month-olds. The items for which ≥ 10 professionals indicated concerns and with higher discordance between the professionals and parents for both boys and girls were "picky eating" for 18-month-olds and "inconsistent amount of food" for 3-year-olds.ConclusionsThe concerns that professionals have with respect to children's diets and the things that parents worry about show gaps. It might be necessary to provide professional counseling for parents to develop a correct understanding of their children's dietary habits.

Project description:Abstract Objective Eating behaviors play important roles in the development of obesity. A better knowledge of the psychological aspects of eating behaviors in individuals with and without obesity and their consequences on daily eating and lifestyle habits would be informative. The Three‐Factor Eating Questionnaire (TFEQ)‐R21 assesses the psychometrics of eating behavior. The objectives of the study were to establish which eating habits were or were not associated with TFEQ eating behaviors, and to quantify the extent to which those eating habits mediated the association between TFEQ eating behaviors and obesity risk. Methods Data were obtained from the Gene and Environment Case‐Control Obesity Study from northern France. It included 2237 individuals with obesity and 403 individuals without obesity. Eating behaviors were assessed according to the TFEQ‐R21. Two activity levels (physical activity and television watching) and six eating habits (e.g., plate size, having one serving or at least two servings of the main meal, …) were evaluated. Regression and mediation analyses were performed. Results Higher cognitive restraint, higher uncontrolled eating (UE) and higher emotional eating (EE) were associated with a higher risk of obesity, independently of each other and of age, sex, socio‐economic status and physical activity. Cognitive restraint was negatively associated with having at least two servings, while UE and EE were associated with several obesogenic habits such as eating in front of the television or eating at night. Each of these obesogenic habits mediated between 3% and 20% of the association between UE or EE and obesity. Conclusions Psychological eating behaviors were associated with several lifestyle and eating habits in both individuals with and without obesity. Moreover, some eating habits partially mediated (between 3% and 20%) the association between TFEQ eating behaviors and obesity risk. For clinicians, this study shows that simple, easy‐to‐ask questions on specific daily eating habits can provide essential information to better understand and manage patients with obesity.
