Sensory profile of picky eaters among college female students.

Picky eaters are at risk of an unbalanced diet, which is critical for women of reproductive age. A sensory profile, which is a potential factor in picky eating, has not been well researched. This study assessed the differences in sensory profile and dietary intake according to the picky eating status among female Japanese undergraduate college students. Cross-sectional data were obtained from the Ochanomizu Health Study conducted in 2018. The questionnaire included items regarding demographic characteristics, picky eating status, sensory profile, and dietary intake. Sensory profile was assessed using the Adult/Adolescent Sensory Profile questionnaire, and dietary intakes were calculated using a brief-type self-administered diet history questionnaire. Among the 111 participants, 23% were picky eaters and 77% were non-picky eaters. The age, body mass index and household status did not differ between the picky eaters and non-picky eaters. Being a picky eater was associated with higher scores on sensory sensitivity and sensation avoiding, and lower thresholds for taste and smell, touch, and auditory stimuli than being a non-picky eater. Of the picky eaters, 58% and 100% were at a high risk for folate and iron deficiencies, respectively, compared to 35% and 81% of non-picky eaters. Nutrition education for picky eaters in reproductive age to increase vegetable dishes comfortably in their diet is suggested to prevent anemia during their future pregnancy.

Association of healthy eating literacy and resident status with energy, nutrients, and food consumption among lean and normal-weight female university students.

BACKGROUND & AIMS: This study aimed to describe the association of healthy eating literacy (HEL) with energy, nutrients, and food consumption in young women who had normal and lean weight at a Japanese university, considering their resident status. METHODS: Cross-sectional data from the Ochanomizu Health Study were used in this study. Participants answered a self-administered, two-part, anonymous survey in 2018 and 2019. A total of 203 female undergraduate students with lean and normal body mass index (BMI) were included in the analysis. Single and stepwise multiple linear regression analysis was used to examine the association of HEL and resident status with healthy food consumption, such as vegetables, fish, and shellfish. The dependent variables were HEL and resident status, and the covariates were age, BMI, and the total metabolic equivalents. RESULTS: The median (25th and 75th percentiles) age, BMI, and total HEL score were 20 (19, 21) years, 20.2 (18.9, 21.3) kg/m 2, and 18 (16, 20), respectively. Resident status and HEL were independently associated with vegetables, fish, and shellfish intake. Participants who had higher total HEL scores and lived in their family home consumed significantly more vegetables (ß = 0.17 and -0.34, p < 0.05) and fish and shellfish (ß = 0.24, -0.28, p < 0.001). CONCLUSION: This study provides an insight into the association between HEL and dietary consumption in young women with normal and lean BMI.

Pd-catalyzed Aerobic Cross-Dehydrogenative Coupling of Catechols with 2-Oxindoles and Benzofuranones: Reactivity Difference Between Monomer and Dimer.

Persistent radicals, which are generated from 2-oxindole or benzofuranone dimers, are useful tools for designing the radical-based cross-coupling reaction to provide molecules containing a quaternary carbon. The persistent radical is accessible from both the dimer and monomer; however, the reactivity difference between these substrates for the oxidative cross-coupling reaction is not fully understood, most likely because of the mechanistic complexity. Here, we present details of an aerobic cross-dehydrogenative coupling (CDC) reaction using various monomers and catechols. UV-Vis analysis and mechanistic control experiments showed that the monomer is less reactive than the dimer under aerobic conditions. Our Pd(II)-BINAP-µ-hydroxo complex significantly improved the reactivity of the monomers for the aerobic CDC reaction with catechols, yielding results comparable to those of the corresponding dimer. The procedure, which enables the generation of the persistent radical in situ, is particularly useful when employing the monomer that is not readily converted to the corresponding dimer.

Changing genetic architecture of body mass index from infancy to early adulthood: an individual based pooled analysis of 25 twin cohorts.

BACKGROUND: Body mass index (BMI) shows strong continuity over childhood and adolescence and high childhood BMI is the strongest predictor of adult obesity. Genetic factors strongly contribute to this continuity, but it is still poorly known how their contribution changes over childhood and adolescence. Thus, we used the genetic twin design to estimate the genetic correlations of BMI from infancy to adulthood and compared them to the genetic correlations of height. METHODS: We pooled individual level data from 25 longitudinal twin cohorts including 38,530 complete twin pairs and having 283,766 longitudinal height and weight measures. The data were analyzed using Cholesky decomposition offering genetic and environmental correlations of BMI and height between all age combinations from 1 to 19 years of age. RESULTS: The genetic correlations of BMI and height were stronger than the trait correlations. For BMI, we found that genetic correlations decreased as the age between the assessments increased, a trend that was especially visible from early to middle childhood. In contrast, for height, the genetic correlations were strong between all ages. Age-to-age correlations between environmental factors shared by co-twins were found for BMI in early childhood but disappeared altogether by middle childhood. For height, shared environmental correlations persisted from infancy to adulthood. CONCLUSIONS: Our results suggest that the genes affecting BMI change over childhood and adolescence leading to decreasing age-to-age genetic correlations. This change is especially visible from early to middle childhood indicating that new genetic factors start to affect BMI in middle childhood. Identifying mediating pathways of these genetic factors can open possibilities for interventions, especially for those children with high genetic predisposition to adult obesity.

Internalizing problems and suffering due to sensory symptoms in children and adolescents with and without autism spectrum disorder.

Sensory symptoms are common in autism spectrum disorder (ASD). Previous studies have shown a positive correlation between sensory symptoms and internalizing problems; however, the role of the suffering due to sensory symptoms is not well understood. In the present study, we hypothesized that the relationship between sensory symptoms and internalizing problems in children is mediated by children's and surrounding people's suffering due to sensory symptoms. Parents of 113 students aged 6-15 years with and without ASD completed questionnaires about their children's autistic traits, sensory symptoms, suffering due to sensory symptoms, and internalizing problems. The results showed that autistic traits and sensory symptoms were distributed as a continuum throughout children with and without ASD. Therefore, we investigated the relationship among variables in children with and without ASD attending regular classes. Structural equation modeling indicated that those who scored higher on sensory symptoms demonstrated greater suffering due to sensory symptoms as predictors of internalizing problems. Our findings provide evidence for developing a support system that specifically reduces suffering due to sensory symptoms, especially for students in regular classes.

Mediating role of sensory differences in the relationship between autistic traits and internalizing problems.

BACKGROUND: Sensory differences are related to the autistic traits, and previous studies have shown a positive correlation between sensory differences and internalizing problems. In this study, we hypothesized that sensory differences and suffering due to sensory differences mediates the relationships between autistic traits and internalizing problems. METHODS: A total of 346 female Japanese university students completed questionnaires regarding their autistic traits, suffering due to sensory differences, and internalizing problems. Moreover, 114 participants completed a questionnaire related to sensory differences. RESULTS: Autistic traits were correlated with Low Registration and Sensation Avoiding. These sensory differences were also correlated with suffering due to sensory differences and internalizing problems. Moreover, path analysis indicated that the higher the suffering due to Low Registration and Sensation Avoiding was, the greater the internalizing problems in those who showed these sensory differences. CONCLUSIONS: Female university students with serious suffering due to sensory differences may need support in managing their suffering and internalizing problems. Further research will help suggest support that these people require, at school and elsewhere.

Courtesy stigma of parents of children with Down syndrome: Adaptation process and transcendent stage.

Courtesy stigma, which arises from close connections to people with stigmatized characteristics, negatively affects interpersonal relations. This study aimed to evaluate courtesy stigma and the adaptation process of parents of children with Down syndrome based on semi-structured interviews with 23 Japanese parents. The interview themes were (a) negatively perceived interpersonal experiences and coping strategies; (b) information disclosure and others' responses; and (c) positively perceived interpersonal experiences. The interview data were transcribed and analyzed based on a grounded theory approach. The results suggested that parents perceived and experienced multidimensional courtesy stigma, and they used various coping strategies categorized in combinations of passive-active and internal-external. All parents disclosed information about their child's diagnosis to others, and reverse disclosure (i.e., revealing own relations with people with disabilities) was characteristically observed thereafter. Through active interaction and reflection, the parents cultivated social relationships, compassion, world views, and community involvement, which led to the transcendent stage. However, internal conflict as a mediator between people with and without Down syndrome re-emerged even after achieving the transcendent stage. These findings could help to develop interventions in genetic counseling for parents to deal with interpersonal relationship difficulties.

Later chronotype is associated with unhealthful plant-based diet quality in young Japanese women.

BACKGROUND: Having a late chronotype, that is, the tendency to go to sleep and wake up at later hours, influences an individual's physical and mental health. Despite a few studies noting the association of chronotype with healthy dietary patterns, this relationship remains unclear. PURPOSE: This study aimed to describe the association of chronotype with healthful and unhealthful plant-based diet quality in female Japanese undergraduate students. DESIGN: Cross-sectional. PARTICIPANTS AND SETTING: A total of 218 female university students in Tokyo, Japan. MAIN OUTCOME MEASURES: Healthful and unhealthful plant-based dietary index-Japanese version (hPDI-J and uPDI-J), calculated using the validated brief-type self-administered diet history questionnaire. STATISTICAL ANALYSES PERFORMED: A five-model stepwise multiple linear regression analysis was conducted. Independent variables were hPDI-J and uPDI-J scores, and dependent variables were various lifestyle habits related to the circadian rhythm and demographic characteristics. RESULTS: Mean (standard deviation) sleep duration, midpoint of sleep, sleep latency time, and social jetlag were 411 (60) min, 03:56 (00:57), 21 (27) min, and 50 (39) min, respectively. Chronotype and several variables, such as residential status, energy and alcohol intake, and nutritional knowledge, were associated with healthful and unhealthful plant-based diet quality. Individuals who had higher hPDI-J scores were more likely to have an earlier chronotype (ß = -0.168, P = 0.019) and better nutritional knowledge (ß = 0.164, P = 0.022) than those with lower hPDI-J scores. Individuals were more likely to have higher uPDI-J scores if they were living alone (ß = -0.301, P < 0.001), had a later chronotype (ß = 0.181, P = 0.001), higher frequency of snacking (ß = 0.164, P = 0.019), lower total energy (ß = -0.445, P < 0.001), and worse nutritional knowledge (ß = -0.172, P = 0.001). CONCLUSION: This study provided new evidence as to the relationship between sleep and dietary habits, the interaction of which may affect women's health.

Is mindful eating sustainable and healthy? A focus on nutritional intake, food consumption, and plant-based dietary patterns among lean and normal-weight female university students in Japan.

PURPOSE: This study aimed to investigate the correlation between mindful eating and nutritional intake, food consumption, and healthful and unhealthful plant-based dietary patterns in young Japanese women. METHODS: The sample comprised 215 female undergraduates who responded to a two-questionnaire anonymous survey conducted in Tokyo, Japan in 2018 and 2019 from November to December. We measured mindful eating status using the Expanded Mindful Eating Scale (EMES) and used Japanese plant-based dietary indices to determine plant-based dietary patterns. Partial correlation analyses were conducted to determine the correlation of mindful eating with energy and nutrient intake, food consumption, and plant-based dietary patterns, after adjusting for demographics and body mass index. RESULTS: Participants with higher sub-scores in "health of the planet" and "awareness and appreciation for food" ate higher quantities of several micronutrients and plant-based foods and were more likely to have a healthful plant-based dietary pattern. They were also less likely to have an unhealthful plant-based dietary pattern. In contrast, participants with higher scores in "non-judgmental awareness" ate less protein, whole grains, and vegetables, and were likely to have an unhealthful plant-based dietary pattern. CONCLUSION: This study is the first to show that young Japanese women with normal or lean body weight were more likely to consume healthful plant-based foods when they ate mindfully. LEVEL V: Opinions of respected authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

Assessing Knowledge-Based and Perceived Health Literacy Among Japanese Adolescents: A Cross-Sectional Study.

Health literacy assessment is a major aspect of planning health education for adolescents. We evaluated the health literacy of Japanese adolescents using both perceived and knowledge-based health literacy scales. Study questionnaires were administered to 773 junior and senior high school students aged 12 to 18 years. We tested a model describing the hierarchical relations between functional, communicative, critical, and knowledge-based health literacy using path analysis. Critical health literacy was found to be influenced by functional, communicative, and knowledge-based health literacy, while functional and knowledge-based health literacy were correlated. The model, with slight modification, was supported. The result indicates that perceived functional health literacy scores did not directly correlate with higher perceived critical health literacy; rather, they only informed critical health literacy when participants had high knowledge-based health literacy.

Formal Aerobic Oxidative Cross-Coupling of Benzofuranones with Azo Compounds Using Pd-µ-hydroxo Complex.

We have developed a catalytic aerobic oxidative dimerization reaction of benzofuranones using a Pd(II)-µ-hydroxo complex. Radical-radical cross-coupling of the resulting dimers with azo compounds enabled the one-pot synthesis of structurally congested benzofuranones having two distinct vicinal all-carbon quaternary centers.

Development and validation of the Expanded Mindful Eating Scale.

PURPOSE: To develop and validate the Expanded Mindful Eating Scale (EMES), an expanded mindful eating model created for the promotion of health and sustainability. DESIGN/METHODOLOGY/APPROACH: A cross-sectional study using self-administered questionnaire surveys on Ochanomizu Health Study (OHS) was conducted. The survey was provided to 1,388 female university students in Tokyo, Japan. Exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and a partial correlation analysis were used to confirm construct and criterion validity. Internal consistency of the EMES was confirmed to calculate Cronbach's alpha. FINDINGS: The response rate was 38.7 % (n = 537). Mean BMI was 20.21 ± 2.12, and 18.8% of them were classified as "lean" (BMI < 18.5). The authors listed 25 items and obtained a final factor structure of five factors and 20 items, as a result of EFA. Through CFA, the authors obtained the following fit indices for a final model: GFI = 0.914, AGFI = 0.890, CFI = 0.870 and RMSEA = 0.061. The total EMES score was significantly correlated with BMI, mindfulness, body dissatisfaction, drive for thinness and life satisfaction (r = -0.138, -0.315, -0.339, -0.281 and 0.149, p < 0.01, respectively). Cronbach's alpha for all items in this scale was 0.687. PRACTICAL IMPLICATIONS: The authors suggest the possibility that practitioners and researchers of mindful eating that includes this new concept can use authors' novel scale as an effective measurement tool. ORIGINALITY/VALUE: The EMES, which can multidimensionally measure the concept of the expanded model of mindful eating was first developed in this study.

Genetic and environmental influences on human height from infancy through adulthood at different levels of parental education.

Genetic factors explain a major proportion of human height variation, but differences in mean stature have also been found between socio-economic categories suggesting a possible effect of environment. By utilizing a classical twin design which allows decomposing the variation of height into genetic and environmental components, we tested the hypothesis that environmental variation in height is greater in offspring of lower educated parents. Twin data from 29 cohorts including 65,978 complete twin pairs with information on height at ages 1 to 69 years and on parental education were pooled allowing the analyses at different ages and in three geographic-cultural regions (Europe, North America and Australia, and East Asia). Parental education mostly showed a positive association with offspring height, with significant associations in mid-childhood and from adolescence onwards. In variance decomposition modeling, the genetic and environmental variance components of height did not show a consistent relation to parental education. A random-effects meta-regression analysis of the aggregate-level data showed a trend towards greater shared environmental variation of height in low parental education families. In conclusion, in our very large dataset from twin cohorts around the globe, these results provide only weak evidence for the study hypothesis.

Parental Education and Genetics of BMI from Infancy to Old Age: A Pooled Analysis of 29 Twin Cohorts.

OBJECTIVE: The objective of this study was to analyze how parental education modifies the genetic and environmental variances of BMI from infancy to old age in three geographic-cultural regions. METHODS: A pooled sample of 29 cohorts including 143,499 twin individuals with information on parental education and BMI from age 1 to 79 years (299,201 BMI measures) was analyzed by genetic twin modeling. RESULTS: Until 4 years of age, parental education was not consistently associated with BMI. Thereafter, higher parental education level was associated with lower BMI in males and females. Total and additive genetic variances of BMI were smaller in the offspring of highly educated parents than in those whose parents had low education levels. Especially in North American and Australian children, environmental factors shared by co-twins also contributed to the higher BMI variation in the low education level category. In Europe and East Asia, the associations of parental education with mean BMI and BMI variance were weaker than in North America and Australia. CONCLUSIONS: Lower parental education level is associated with higher mean BMI and larger genetic variance of BMI after early childhood, especially in the obesogenic macro-environment. The interplay among genetic predisposition, childhood social environment, and macro-social context is important for socioeconomic differences in BMI.

Do health beliefs, personality traits, and interpersonal concerns predict TB prevention behavior among Japanese adults?

Despite public health measures and health-promotion efforts, the decline in tuberculosis (TB) morbidity in Japan has been slow, with a higher TB incidence rate relative to those observed in most developed countries. Because health behavior depends on multiple factors and is formulated within a social context, a theory-driven model would be necessary to increase TB prevention behavior. Based upon the Health Belief Model, this study examined the effects of health beliefs, personality traits, and social factors on TB prevention behavior among Japanese adults. A cross-sectional survey was carried out with a nationally representative sample (N = 911; 50.9% women; mean age 49.5, SD = 14.1). Path analyses gave empirical support for the hypothesized model, suggesting that TB prevention behaviors are influenced by not only perceived susceptibility to the illness but also social factors such as cues to action and one's concern to benefit others. The findings have implications for research examining health communication tailored to individual differences in personality and interpersonal concern.

Quality of life in Japanese couples during the transition to parenthood.

OBJECTIVE: This study aimed to examine the quality of life (QOL) in Japanese couples during the transition to parenthood with their first child. BACKGROUND: Relevant literature suggests that the health status of women drop during pregnancy and the postpartum period. However, less is known about their partner's well-being during the transition to parenthood and little research has addressed the relationship between couples' QOL across multiple domains. METHOD: Participants included 9216 married Japanese men and women, including 3729 couples, who were expecting or raising their first child under the age of three. They independently completed questionnaires on baseline demographics and on WHOQOL-BREF. RESULTS: Men showed higher scores for psychological QOL, while women had higher scores for social and environment QOL. A significant interaction between gender and stage of transition to parenthood was found. The moderating effect of age between the stage and QOL was found for men on the physical and psychological domains. Couples' QOL scores were weakly to moderately correlated. CONCLUSION: Findings suggest that both men and women had lower QOL, with the exception of women's physical QOL, after childbirth, but they showed different trends during the transition to parenthood across different domains of QOL.

QOL and sociodemographic factors among first-time parents in Japan: a multilevel analysis.

PURPOSE: The present study aimed to examine the relationship between sociodemographic factors and domains of quality of life (QOL) among married adults in Japan who were either rearing or expecting their first child. Our research focus was on whether different sociodemographic variables interacted with each other in predicting the first-time parents' QOL. METHOD: In total, 4374 (mean age = 34.9 years, SD = 8.4, range 18-71) community-based married couples pooled from two surveys provided their sociodemographic information (i.e., age, years of education, and annual income) and responded to the brief version of the QOL instrument developed by the World Health Organization (WHOQOL-BREF in Psychological Medicine 28(3):551-555, 1998). RESULTS: Series of multilevel regression analyses revealed that household annual income and education were associated with all domains of QOL, and other sociodemographic variables worked in a domain-specific manner. In addition, the effect of educational attainment on psychological domain was significant for mothers only, whereas the effects of household income on psychological and environmental domains were stronger for the younger (below age 26) than the older (over 43) couples. CONCLUSION: The effects of sociodemographic factors at couple as well as individual levels on the first-time parents' QOL were examined for the first time in Japan using couple data. In addition to corroborating previous findings on the main effects concerning these variables, the present study demonstrated the complex patterns of interaction across different levels. These findings provide evidence for the need for financial and health measures targeted at specific parent populations.

One-Pot Synthesis of α-Amino Acids through Carboxylation of Ammonium Ylides with CO2 Followed by Alkyl Migration.

A simple, yet powerful protocol for α-amino acid synthesis using carbon dioxide (CO2) was developed. α-Amino silanes could undergo four successive reactions (formation of ammonium salt, carboxylation, esterification, and 2,3- or 1,2-Stevens rearrangement) in the presence of allylic or benzylic halides under a CO2 atmosphere (1 atm). It is noteworthy that carboxylation at the position adjacent to a nitrogen atom proceeded via an ammonium ylide intermediate under mild conditions.

Stereoretentive Addition of N-tert-Butylsulfonyl-α-Amido Silanes to Aldehydes, Ketones, α,ß-Unsaturated Esters, and Imines.

Enantioenriched N-tert-butylsulfonyl-α-amido silanes were successfully reacted with aldehydes, ketones, imines, and α,ß-unsaturated esters in the presence of a sub-stoichiometric amount of CsF (0.5 equiv) in 1,2-dimethoxyethane (DME) at -20 °C to afford the corresponding coupling products with up to 89 % enantiospecificity in a retentive manner.

Au-Catalyzed Pentannulation Reaction of Propargylic Esters Occurring at C(sp(3))-H Site.

A gold-catalyzed cascade cyclization reaction of easily accessible propargylic esters to cyclopentenones has been developed. This transformation features an unprecedented pentannulation reaction of propargylic esters which occurs at an unactivated C(sp(3))-H site to efficiently produce functionalized mono-, bis-, and tricyclic cyclopentenones.
