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 sens...

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 characteristical...

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 (β = -0.174, P = 0.014) and better nutritional knowledge (β = -0.149, P = 0.034) than those with lower hPDI-J scores. Individuals were more likely to have higher uPDI-J scores if they were living alone (β = 0.267, P < 0.001), had a later chronotype (β = 0.210, P < 0.001), higher frequency of snacking (β = -0.166, P = 0.002), lower total energy (β = -0.468, P < 0.001), and worse nutritional knowledge (β = 0.176, 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.

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. 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. 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. Opinions of respected authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

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.

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.FindingsThe 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...

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 BM...

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.
