[An examination of relevant factors attributable to child health, food behavior, and lifestyle concerns of parents with infants aged at least 18 months: With a view to expanding into Shokuiku (food and nutrition education)].

Objectives　This study focused on food after weaning and examined the children's diet and home environmental factors that influence parents' concerns during health checkup for infants (aged 1.6 and 3 years).Methods　In the analysis, 646 participants, excluding invalid responses, who cooperated with the survey during health checkup for 1.6- and 3-year-old in the Tohoku, Chubu, and Chugoku regions from March 2019 to January 2020, were included. The survey included 56 items of dietary, lifestyle, and health concerns (yes/no answers), child attributes, and frequency of food intake (six options, 18 types). Concern factors were extracted by factor analysis. The association between the worry scores and each factor was analyzed.Results　The 1.6- and 3-year-olds were associated with high scores for (health awareness and lifestyle) and low fruit intake, high salty snacks intake, and low subjective economic status, high scores for (diet content and atmosphere) and low intakes of carotene-rich vegetables, other vegetables, seaweed, and fruits, high scores for (interest and motivation in food) and low carotene-rich vegetables intake, high scores for (food experience and behavior) and high cereals (bread) intake, low subjective economic status. The 3-year-olds were associated with high scores and being boys.Conclusion　We extracted four worry factors that parents with children after the weaning period have and clarified the factors related to each factor and group characteristics.

Epitope-Based Specific Antibody Modifications.

Modified antibodies have essential roles in analytic, diagnostic, and therapeutic uses, and thus, these antibodies are required to have optimal physical and biological properties. Consequently, the development of methods for site-selective antibody modification is crucial. Herein, we used epitope-based affinity labeling to introduce a Fab region-selective antibody modification method. Although labeling that exploits the high affinity between an antibody and its epitope may appear straightforward, it remains challenging probably because of the loss of target affinity caused by modification around the epitope-binding site. By thoroughly screening the modifying agent structure, reaction conditions, and purification methods, we developed an efficient method for the selective modification of the Fab region of the antibody while maintaining the high affinity for the epitope.

Gap between the concerns of healthcare professionals and parents' perceptions regarding dietary habits for 18-month- and 3-year-old children in Japan.

BACKGROUND: A 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. METHODS: The 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. RESULTS: Many 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. CONCLUSIONS: The 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.

Validation of Dietary Intake Estimated by Web-Based Dietary Assessment Methods and Usability Using Dietary Records or 24-h Dietary Recalls: A Scoping Review.

The goal was to summarize studies comparing the accuracy of web-based dietary assessments with those of conventional face-to-face or paper-based assessments using 24-h dietary recall or dietary record methods in the general population. Using two databases, mean differences and correlation coefficients (CCs) for intakes of energy, macronutrients, sodium, vegetables, and fruits were extracted from each study independently by the authors. We also collected information regarding usability from articles reporting this. From 17 articles included in this review, the mean dietary intake differences in the web-based dietary assessment compared to conventional methods, were -11.5-16.1% for energy, -12.1-14.9% for protein, -16.7-17.6% for fat, -10.8-8.0% for carbohydrates, -11.2-9.6% for sodium, -27.4-3.9% for vegetables, and -5.1-47.6% for fruits. The CC was 0.17-0.88 for energy, protein, fat, carbohydrates, and sodium, and 0.23-0.85 for vegetables and fruits. In three out of four studies reporting usability, more than half of the participants preferred the web-based dietary assessment. In conclusion, % difference and CC of dietary intake were acceptable in both web-based dietary records and 24-h dietary recalls. The findings from this review highlight the possibility of wide-spread application of the web-based dietary assessment in the future.

Direct and Indirect Harassment Experiences and Burnout among Academic Faculty in Japan.

The purpose of this study is three-fold: (1) to compare harassment (sexual, gender, and academic harassment both directly and indirectly experienced - i.e. "directly harassed" and "have seen or heard of someone who experienced harassment", respectively) experienced by males and females, (2) to investigate whether such experiences correlate with burnout, and (3) to explore whether social support might mitigate any such relationship between harassment and burnout. This cross-sectional study was conducted at a private university in Japan in February 2014 and is based on a work-life balance survey obtained from 330 academic faculty members. We investigated the association between each of the six subcategories of harassment (direct and indirect forms of each of the three types) and burnout using general linear regression models; we then evaluated interactions between harassment and social support in these models. The prevalence of direct and indirect experiences of harassment was higher in females than in males for all three types of harassment. Males showed higher burnout scores if they had direct experiences of harassment. There were significant interactions between social support and the direct experience of harassment; high social support mitigated the effect size of direct harassment on burnout among males. Females showed higher burnout scores if they had indirect experiences of harassment. However, the same buffering effect of social support on burnout as observed in males was not observed in females. Direct harassment experiences increased the risk of burnout in males, and indirect harassment experiences increased burnout in females.

Effects of gaps in priorities between ideal and real lives on psychological burnout among academic faculty members at a medical university in Japan: a cross-sectional study.

BACKGROUND: Accumulating evidence from medical workforce research indicates that poor work/life balance and increased work/home conflict induce psychological distress. In this study we aim to examine the existence of a priority gap between ideal and real lives, and its association with psychological burnout among academic professionals. METHODS: This cross-sectional survey, conducted in 2014, included faculty members (228 men, 102 women) at a single medical university in Tokyo, Japan. The outcome of interest was psychological burnout, measured with a validated inventory. Discordance between ideal- and real-life priorities, based on participants' responses (work, family, individual life, combinations thereof), was defined as a priority gap. RESULTS: The majority (64%) of participants chose "work" as the greatest priority in real life, but only 28% chose "work" as the greatest priority in their conception of an ideal life. Priority gaps were identified in 59.5% of respondents. A stepwise multivariable general linear model demonstrated that burnout scores were associated positively with respondents' current position (P < 0.0018) and the presence of a priority gap (P < 0.0001), and negatively with the presence of social support (P < 0.0001). Among participants reporting priority gaps, burnout scores were significantly lower in those with children than in those with no children (P interaction = 0.011); no such trend was observed in participants with no priority gap. CONCLUSIONS: A gap in priorities between an ideal and real life was associated with an increased risk of burnout, and the presence of children, which is a type of "family" social support, had a mitigating effect on burnout among those reporting priority gaps.

A relationship between a level of hemoglobin after delivery and exclusive breastfeeding initiation at a baby friendly hospital in Japan.

BACKGROUND: The recent National Nutrition Survey of 2013 demonstrated that 16.7% of women in childbearing age are underweight, and 5.0-10.0% of these women manifested a Hemoglobin (Hb) level less than 11.0 g/dl. The purpose of this study was to investigate if such maternal nutritional status affects success of exclusive breastfeeding (EBF) practice. METHODS: This cross-sectional study investigated 1532 dyads of mothers and infants with full-term singleton pregnancies delivered during 2011 at a perinatal center in Tokyo. Outcome is EBF initiation defined as the successful practice at discharge and 1 month after discharge. A logistic regression model was applied to investigate the impact of Hb levels (<9.0, 9.0-10.9, and ≥11.0 g/dl) measured within 2-3 days after delivery on successful EBF initiation adjusting for covariates including bleeding at delivery. RESULTS: Mean age was 34 years, 23.0% were underweight and 63.0% were nulliparous. The success rate for EBF initiation at discharge and at 1 month after discharge was 72.7 and 63.0% for a Hb level <9.0 g/dl, 81.9 and 68.9% for a Hb level of 9.0-10.9 g/dl, and 85.7 and 75.9% for a Hb level ≥11.0 g/dl, respectively. A logistic regression model showed that risk factors of unsuccessful EBF practice at discharge and 1 month after discharge included lower level Hb categories (P < 0.001 and P < 0.001), postpartum hemorrhage > 500 ml (P = 0.089 and P = 0.011), maternal age (P < 0.001 and P < 0.001), nulliparity (P < 0.0001 and P < 0.001), pregnancy-induced hypertension (P = 0.002 and P = 0.012), gestational week (P = 0.006 and P = 0.002), Low Birth Weight (LBW) (P < 0.001 and P < 0.001), and immediate separation (P < 0.001 and P = 0.020). After adjusting for the covariates, compared with a Hb level ≥11.0 g/dl, a Hb level <9.0 g/dl was significantly associated with unsuccessful EBF initiation at discharge [odds ratio (OR): 2.15; 95% confidence interval (CI): 1.37-3.39] and at 1 month after discharge (OR: 1.63; 95% CI: 1.10-2.42), and a Hb level of 9.0-10.9 g/dl also was significant at 1 month after discharge (OR: 1.35; 95% CI: 1.04-1.75). Pre-pregnancy underweight was not associated with success of EBF practice both at hospital discharge and 1 month after discharge. CONCLUSION: Maternal severe anemia after delivery was associated with the risk of unsuccessful initiation of EBF even after adjusting for bleeding at delivery, suggesting the importance of dietary management especially in the later trimester.

Factors Associated with Blood Loss after Delivery in 1,294 Mothers with Full-Term Singleton Baby.

OBJECTIVES: To clarify the predisposing factors associated with blood loss after delivery in mothers with full-term singleton babies. METHODS: In this retrospective cohort study, we investigated 1,294 women who delivered singleton babies vaginally in 2011 at a medical center in Tokyo. We determined the amount of blood loss after delivery and covariates of age, parity, pre pregnancy body mass index (BMI), gestational weight gain (GWG), gestational week, pregnancy complications, lifestyles of smoking and drinking, placental weight, and infant weight and sex. RESULTS: The majority of participants had lost less than 500 ml of blood (n=868, 67%), 21% lost between 500-799 ml of blood (n=273), 12% lost 800 ml or more of blood (n=153). The amount of blood loss statistically increased (p<0.001) as pre pregnancy BMI category level increased from underweight (<18.5 kg/m2), normal (18.5-22.9 kg/m2), to overweight/obesity (≥23 kg/m2). Compared with the least category of GWG <8.2 kg, ≥8.2 kg GWG was statistically associated with a larger amount of blood loss category (p=0.032). Multinomial logistic regression analyses demonstrated that with the reference pre pregnancy BMI 18.5-22.9 kg/m2, obese and obesity mothers with pre pregnancy BMI ≥23 kg/m2 were at an increased risk of blood loss [OR 2.28, 95%confidence interval (95%CI): 1.48-3.50 for the category of 500-799 ml and OR 2.15, 95%CI: 1.29-3.59 for a category of 800 ml≤)]. In addition, pregnancy induced hypertension (PIH) (p=0.010) and infant weight (p<0.0001) significantly increased the risk of blood loss. CONCLUSIONS: In mothers with full-term singleton babies, increased pre pregnancy BMI overweight/obesity, PIH, and infant weight, were suggested to be risk factors for increased amount of blood loss.

Organizational climate with gender equity and burnout among university academics in Japan.

We investigated relationships between the perception of organizational climate with gender equity and psychological health among 94 women and 211 men in a Japanese private university in 2015 using the Copenhagen Burnout Inventory (i.e., personal, work-related and student-related burnout). Perceptions of organizational climate with respect to gender equity were measured with two scales including organizational engagement with a gender equal society in the workplace (consisting of three domains of 'Women utilization', 'Organizational promotion of gender equal society' and 'Consultation service'); and a gender inequality in academia scale that had been previously developed. Multivariable linear models demonstrated significant statistical interactions between gender and perceptions of organizational climate; 'Women utilization' or lack of 'Inequality in academia' alleviated burnout only in women. In consequence of this gender difference, when 'Women utilization' was at a lower level, both personal (p=.038) and work-related (p=.010) burnout scores were higher in women, and the student-related burnout score was lower in women when they perceived less inequality in academia than in men (p=.030). As such, it is suggested organizational fairness for gender equity may be a useful tool to help mitigate psychological burnout among women in academia.

[Checklist Development for Women-Doctor-Friendly Working Conditions in a Hospital Setting].

OBJECTIVES: This study aims to develop a scale of "women-doctor-friendly working conditions in a hospital setting". METHODS: A task team consisting of relevant people including a medical doctor and a hospital personnel identified 36 items related to women-doctor-friendly working conditions. From December in 2012 to January in 2013, we sent a self-administered questionnaire to 807 full-time employees including faculty members and medical doctors who worked for a university-affiliated hospital. We asked them to score the extent to which they think it is necessary for women doctors to balance between work and gender role responsibilities on the basis of the Likert scale. We carried out a factor analysis and computed Cronbach's alpha to develop a scale and investigated its construct validity and reliability. RESULTS: Of the 807 employees, 291 returned the questionnaires (response rate, 36.1%). The item-total correlation (between an individual item score and the total score) coefficient was in the range from 0.44 to 0.68. In factor analysis, we deleted six items, and five factors were extracted on the basis of the least likelihood method with the oblique Promax rotation. The factors were termed "gender equality action in an organization", "the compliance of care leave in both sexes and parental leave in men", "balance between life events and work", "childcare support at the workplace", and "flexible employment status". The Cronbach's alpha values of all the factors and the total items were 0.82-0.89 and 0.93, respectively, suggesting that the scale we developed has high reliability. CONCLUSIONS: The result indicated that the scale of women-doctor-friendly working conditions consisting of five factors with 30 items is highly validated and reliable.

The difficulty of professional continuation among female doctors in Japan: a qualitative study of alumnae of 13 medical schools in Japan.

OBJECTIVES: To investigate the difficulties Japanese female doctors face in continuing professional practice. DESIGN: A qualitative study using the Kawakita Jiro method. SETTING: A survey conducted in 2011 of 13 private Japanese medical school alumni associations. PARTICIPANTS: 359 female doctors. PRIMARY OUTCOME MEASURES: Barriers of balancing work and gender role. RESULTS: The female doctors reported that professional practice was a struggle with long working hours due to a current shortage of doctors in Japan. There was also a severe shortage of childcare facilities in the workplace. Some women appeared to have low confidence in balancing the physician's job and personal life, resulting in low levels of professional pursuit. There appeared to be two types of stereotypical gender roles, including one expected from society, stating that "child rearing is a woman's job", and the other perceived by the women themselves, that some women had a very strong desire to raise their own children. Male doctors and some female doctors who were single or older were perceived to be less enthusiastic about supporting women who worked while raising children because these coworkers feared that they would have to perform additional work as a result of the women taking long periods of leave. CONCLUSIONS: Important factors identified for promoting the continuation of professional practice among female doctors in Japan were the need to improve working conditions, including cutting back on long working hours, a solution to the shortage of nurseries, a need for the introduction of educational interventions to clarify professional responsibilities, and redefinition of the gender division of labour for male and female doctors. In addition, we identified a need to modernise current employment practices by introducing temporary posts to cover maternity leave and introducing flexible working hours during specialist training, thus supporting and encouraging more women to continue their medical careers.

Understanding of sodium content labeled on food packages by Japanese people.

Salt reduction is one of the most important lifestyle modifications for the prevention of hypertension. The health promotion law regulates the labeling of the nutrient content of food in Japan and, the level of sodium, not salt (sodium chloride), has to be printed on the labels of manufactured foods. In order to control their salt intake, consumers need to apply a conversion factor to the sodium levels listed on the labels to obtain the salt equivalent. However, it is not known whether people have the knowledge appropriate for making the conversion. We carried out a questionnaire survey at the 7th National Shokuiku (food education) Conference in 2012, asking subjects to determine the salt equivalent of 1000 mg of sodium on food labels. We also asked about the target values of salt reduction in grams in the Dietary Reference Intakes for Japanese 2010 (DRI2010) and the Guidelines for Management of Hypertension 2009 by the Japanese Society of Hypertension (JSH2009). We analyzed the data from 683 respondents (169 men and 514 women); only 13.3% of respondents gave a correct answer for the salt equivalent of 1000 mg of sodium (2.50-2.60 g), whereas 61.8 and 40.4% of respondents chose the correct target values for salt reduction according to DRI2010 and JSH2009, respectively. In conclusion, few people could convert sodium content to salt, which suggested difficulty in using food labels to control their salt intake. Salt content in grams, not sodium content, should be labeled on food packages for effective salt reduction and prevention of hypertension.
