AbstractObjectivesExposure to inorganic arsenic (iAs) is a world-wide health concern. We reported that Japanese children and pregnant women are exposed to moderate levels of iAs through food. Reducing iAs contamination from foods of high iAs is an important issue unique in Japan. Integrated iAs is methylated to less toxic organic forms, and S-adenosyl-L-methyonine (SAM), a common methyl-donor of DNA and histones, is utilized in this process. Chronic consumption of SAM by iAs metabolism due to exposure to iAs might alter the epigenetic modification of genome. The SAM biosynthesis pathway is dependent on folate cycle, and it is possible that ingestion of sufficient folic acid (FA) is protective to iAs induced toxicity.MethodsIn the course of our cross-sectional body burden analyses of Pb and iAs in Japanese children and pregnant women, termed “PbAs study”, FA concentration in serum of 104 pregnant women was measured.ResultsMean (±SEM) of serum FA concentration was 15.8 ± 1.3 (ng/mL). There are significant number of people showing very high FA (>30 ng/ mL), and large fraction of them were taking supplements daily.ConclusionsThese results suggested that level of FA ingestion of Japanese pregnant women is high for supporting normal fetal development.

Psychological Well Being

Background:Sedentary behaviors (SB) are associated with health indicators; however, there are currently very few studies that have examined these associations, especially in conjunction with psychological factors, in children. The current study examined the independent relationship between objectively assessed SB, and indicators of obesity and psychological well-being, among Japanese children.Methods:A total of 967 elementary-school children completed a cross-sectional survey. SB was measured with accelerometers for 7 consecutive days. Psychological well-being data (eg, anxiety and behavior problems) were collected via a self-report questionnaire. To determine the relationship of SB with degree of obesity and psychological well-being, linear regression analyses were conducted to relate the indicators of obesity and psychological well-being on SB, adjusted by gender, grade, percentage of moderate-to-vigorous physical activity per day, duration spent wearing the accelerometer, and degree of obesity.Results:SB was significantly related to behavioral/emotional problems (β = .280, P = .010, R2 = .015). There was a statistically significant relationship between SB and anxiety (β = .206, P = .059, R2 = .007). No significant association with degree of obesity was found.Conclusions:Excess SB relates higher levels of behavioral/emotional problems and anxiety. These results can inspire the development of interventions that promote well-being and enhance psychological health, by focusing on SB in Japanese children.

Objective: This study presents an analysis of three-dimensional facial forms of normal Japanese children. Design and Setting: Cross-sectional data (n = 247) were available from the Ikeda Public Health Center. Patients and Participants: Three groups of children (ninety-seven 4-month-old infants, fifty-four 1.5-year-old children, and eighty 3.5-year-old children) were analyzed using a three-dimensional anthropometric technique. Main Outcome Measures: Three-dimensional coordinates of facial landmarks were extracted automatically from XYZ data sets and photo images of an optical surface scanner. Results: Only minor gender differences were noted. Lip height was not correlated with other facial dimensions. There was a significant correlation between upper face, nose, and mouth widths. Compared with adults, the upper face width was larger (approximately 70% to 80% of adults) than the middle and lower parts of the face. Width ratios were greater than height and depth ratios. The lip height ratio, however, was larger than the lip width ratio, and the angle of the cupid's bow was more acute in children. The angle of the nose was more obtuse, particularly in the axial plane. Conclusions: In cleft lip surgery involving young children, there may be no need to consider gender differences. Some characteristic differences exist between children and adults, however, and normal standards for children would be helpful in plastic surgery.

This study is an attempt to depict the learning process of AP in Japanese children in a cross-sectional design. In this study, 104 children of 4 to 10 years of age in a music school were tested. The children had been trained within a music education system of the school since they entered the school at the age of 4. They had received a one-hour keyboard lesson a week in school and probably had everyday practice at home. The training during the initial 2-year course emphasized imitative singing with syllables in the fixed-do system while playing on the keyboard at the same time. In this training, particular emphasis was placed on establishing associations between pitches and solfège labels. In the AP test, test tones presented to the children ranged from C3 (131 Hz) to B5 (988 Hz). Children were instructed to name each tone out loud as rapidly as possible. The test score markedly increased for a fairly good number of the children with remarkable improvement from the age of 4 to 7. Children seemed to learn pitches in order of their appearance in music lessons; first, white-key notes, then black-key notes. However, one should be cautious about concluding from the present results that anyone can learn to develop AP with appropriate training, because there may be confounding factors (e.g., sampling bias and a certain dropout rate). Nevertheless, the present results are consistent with the early-learning theory of AP, and may explain the existence of partial AP (greater accuracy for white-key notes) and a high prevalence of AP in Japan.

Abstract Objective: To examine the association between the amount of time spent at childcare and diet quality in 668 Japanese children aged 1·5–6 years. Design: A cross-sectional design was used. Dietary information was collected using dietary records (1 d for children aged 1·5–2 years and 2 d for children aged 3–6 years). Diet quality was assessed by counting the number of nutrients not meeting the Japanese Dietary Reference Intakes (DRI). Each child’s guardian reported the average amount of time spent at childcare per d for the previous 1 month. Setting: In total, 315 childcare centres located in twenty-four areas in Japan. Participants: In total, 753 children aged 1·5–6 years who attend childcare facilities. Results: After adjustment for potential confounders, OR for the low diet quality (≥ 5 of twenty nutrients not meeting DRI) in long (≥10 h/d) v. medium (8–10 h/d) childcare hours was 4·81 (95 % CI 1·96, 11·8) among children aged 5–6 years. There was no significant association in children aged 1·5–2 and 3–4 years. Conclusion: This study showed that long time spent at childcare was strongly associated with low diet quality among children aged 5–6 years, but not those aged 1·5–2 and 3–4 years. More research is needed to clarify different associations in each age group.

Abstract Background: Nowadays, the allergic diseases are affecting the population at worldwide level and Cuba does not escape to this, inside the aeroallergens that trigger the crises we can find the pollens. The main goals of this study were to determine the allergenic sensitization to pollens in allergic patients and their relationship with the presence of allergic diseases.Methods: A cross-sectional descriptive observational study was performed in patients suffering from asthma, rhinitis, allergic rhino-conjunctivitis, atopic dermatitis and allergic conjunctivitis. All patients underwent an allergic clinical history and skin prick test with allergenic extracts of Helianthus annus, Cosmos bipinnatus, Cynodon dactylon, Quercus sp, Eucalyptus sp . Frequencies and percentages were determined for its analysis.Results: Thirty-three patients were studied. The average age was found in the third decade of life, with a predominance in women. More than half of the patients were sensitized to pollens and 24.24% of them were polysensitized; the most frequent pollen was the cynodon dactylon . The patients with rhinitis were the most sensitized with the pollens.Conclusions: There is sensitization to pollen in our patients.
