Similarities and discrepancies between commercially available bioelectrical impedance analysis system and dual-energy X-ray absorptiometry for body composition assessment in 10-14-year-old children.

A variety of easy-to-use commercial bioelectrical impedance appliances are available. The aim of this study was to examine the usefulness of a commercially available body composition meter using bioelectrical impedance analysis (BIA) by comparing its measurement results with those obtained from dual-energy X-ray absorptiometry (DXA). The participants were 443 children aged from 10 to 14 years (226 boys and 217 girls).

Associations among perceived health competence, effortful control, self-control, and personality traits in Japanese university students.

Perceived health competence is thought to contribute to lifelong healthy behavior. However, the factors that affect perceived health competence have not been investigated. We investigated the associations among perceived health competence, effortful control, self-control, and personality traits in university students and proposed a model of how these factors affect perceived health competence.

Association between the recognition of muscle mass and exercise habits or eating behaviors in female college students.

This study aimed to examine the association between muscle mass and perception of body shape, desired body shape, physical strength, exercise habits, and eating behaviors. Height, weight, and body composition in 270 female university students were measured. The questionnaire on body shape perception, desired body shape, dieting experience, current, and past exercise habits, exercise preference, and eating behaviors were administered.

Attitude toward breakfast mediates the associations of wake time and appetite for breakfast with frequency of eating breakfast.

Purpose: We investigated associations among attitude toward breakfast, appetite for breakfast, wake time, personality traits, self-esteem, and frequency of eating breakfast in university students and proposed a model of factors affecting the frequency of eating breakfast.

Methods: The participants, 555 Japanese university students (177 men, 378 women), completed a questionnaire about their height and weight, living with family, wake time, frequency of eating breakfast, appetite for breakfast, attitude toward breakfast, personality traits, and self-esteem. Appetite for breakfast was evaluated with a four-point Likert-type scale.

Psychometric properties of the Japanese version of the Dutch Eating Behavior Questionnaire for Children.

This study aimed to evaluate the psychometric properties of the 20-item Japanese version of the Dutch Eating Behavior Questionnaire for Children (DEBQ-C). A population-based sample of 502 Japanese school children who were fifth- and sixth-graders in elementary schools and first- and second-graders in junior high schools was assessed. A sample was randomly split into two subsamples, one for exploratory factor analysis (EFA) and another for confirmatory factor analysis (CFA).

Involvement of glutamatergic mechanisms in the median preoptic nucleus in the dipsogenic response induced by angiotensinergic activation of the subfornical organ in rats.

Experiments were done to investigate the role of glutamatergic systems in the median preoptic nucleus (MnPO) in the water ingestion induced by administration of angiotensin II (ANG II) in the subfornical organ (SFO) in the awake rat. Microdialysis methods were utilized to quantify the extracellular content of glutamate (Glu) in the region of MnPO. Microinjection of ANG II (10 M) into the SFO significantly increased the release of Glu in the MnPO in the rats under the condition that water is available for drinking and the rats under the condition that water is not available for drinking.

Association of anthropometric status, perceived stress, and personality traits with eating behavior in university students.

Purpose: We investigated the association of anthropometric status, perceived stress, and personality traits with eating behavior in university students.

Methods: The participants, 1546 Japanese university students (964 males, 582 females), completed a questionnaire which asked for their current height and weight, ideal height and weight, eating behaviors, perceived stress, and personality traits.

Results: Restrained eating was higher in normal-weight participants compared with underweight participants in both males and females (p < 0.

Association of social support with gratitude and sense of coherence in Japanese young women: a cross-sectional study.

Purpose: Recent studies have shown that perceived social support is associated with gratitude and sense of coherence, but evidence for this concept remains scarce. In the present study, we investigated relationships between social support, gratitude, and sense of coherence, focusing on the construct of and source of social support among young women.

Methods: The study was conducted in 2014 in Japan.
