RESUMEN
Social support is an important factor in reducing fear of childbirth (FOC). Recently, the Internet and Social Networking Services (SNS) have become new forms of social support. However, it is unclear whether such support can reduce pregnant women's fear. This study aimed to investigate the association between FOC and social support through the Internet and SNS in pregnant women. A cross-sectional study using a web-based questionnaire including questions about FOC, social support, the Internet and SNS usage, psychological variables, and sociodemographic variables was conducted. Data from 111 participants were analyzed. A greater number of social support from people who are often seen during pregnancy, and becoming relieved by interaction with others through the Internet and SNS were negatively associated with FOC. This study showed that face-to-face social support was associated with lower FOC, while social support through the Internet and SNS was not. Further research is needed on how to use Internet and SNS to reduce FOC in pregnant women.

AIM: To describe national standard care for newborn bathing and its influential factors. METHODS: A global survey was conducted using a web-based questionnaire. The targeted countries were 166 member countries of either the International Confederation of Midwives (ICM) or the International Council of Nurses (ICN). An eligible person included someone well informed of midwifery education/training or neonatal care, including newborn bathing, in their country. To examine the factors associated with the standard care for newborn bathing, information on mean annual temperature, precipitation, gross domestic product per capita, and basic water coverage was collected as external factors. Student's t tests and Chi-square tests were used for analysis. RESULTS: Care standards were identified in 46 countries: seven from Africa, eight from the Americas, 15 from Asia, 14 from Europe, and two from Oceania. In most countries, newborns were bathed with warm water in a tub within 10 min. Bathing frequency, moisturization, and use of soap or cleanser varied by country. There were significant associations between bathing frequency and temperature and between moisturization and precipitation. CONCLUSION: The national standard care for newborn bathing in each country was unique. Standard bathing care was associated with the climate. More consideration should be given to the differences in standard care for newborn bathing between countries when interpreting existing studies and conducting future studies on neonatal skin care.

This study aimed to determine the association of serum docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) levels with dietary intakes and supplement use during pregnancy. This prospective observational study was conducted at a university hospital in Tokyo, Japan. Participants in their second and third trimesters were given a self-administered questionnaire assessing the frequency of DHA and EPA supplement use in the past month and a brief-type self-administered diet history questionnaire. Non-fasting serum DHA and EPA levels were analysed using gas chromatography. Differences in biomarkers by frequency of supplement use were determined using multiple comparison analyses, and Spearman's correlation coefficient was used to determine biomarkers and DHA and EPA intakes by food group. Of the 116 participants, 11 (9â 5 %) in the second trimester and 18 (15â 5 %) in the third trimester regularly used supplements (≥5 times per week). Regular users had higher serum DHA and EPA levels than never users in the second and third trimesters. Dietary DHA and EPA intake from fish and shellfish was positively correlated with serum DHA and EPA in the second and third trimesters. Supplement use ≥5 times per week and fish and shellfish intake were associated with high serum DHA and EPA levels.

The "Humanization of Childbirth" Project is one of the various maternity care models that respect women and their newborn children. For more than a quarter of a century, the Japan International Cooperation Agency (JICA) has been implementing technical cooperation projects worldwide that place the humanization of childbirth at the center of the concept. By reviewing the project reports, the following 11 key processes were found for the formulation and implementation of future projects for the humanized maternity care: i) project-finding/exploration of unmet needs, ii) identification of local key persons, iii) organization of a project team and a back-up committee, iv) development of an action plan, v) sharing of concepts, vi) development of local leadership, vii) organization of infrastructure, viii) final evaluation and wrap-up seminar, ix) ensuring sustainability, x) development of younger generation experts, and xi) sustainable and autonomous action.
RESUMEN
Nausea and vomiting in pregnancy (NVP) is a common symptom. Although the influence of NVP during the first trimester on dietary intake and birth outcomes has been revealed, no study has focused on NVP during the second trimester. This study aimed to reveal whether NVP severity during the second trimester is associated with dietary intake, gestational weight gain (GWG), birth weight, and delivery week. Participants completed a questionnaire at 18-27 gestational weeks. NVP severity was assessed using the modified Pregnancy-Unique Quantification of Emesis and Nausea scale in the questionnaire. Dietary habits were assessed using a brief-type diet history questionnaire. In total, 825 responses were analyzed: 202 (24.5%), 135 (16.4%), and 8 (1.0%) women reported mild, moderate, and severe NVP, respectively; 480 (58.2%) women did not have NVP during the second trimester. No significant association was observed between energy and nutrient intake and no/mild and moderate/severe NVP. Women with moderate/severe NVP had lower total GWG than those with no/mild NVP (p = 0.007). There was no significant difference in low birth weight and preterm birth rates (p = 0.246 and p = 0.604). This is the first study to investigate whether NVP severity during the second trimester is associated with dietary intake and birth outcomes.

OBJECTIVES: Inadequate gestational weight gain (GWG) has been associated with low birth weight (LBW). However, factors associated with inadequate GWG in Japan remain unclear. Here, we aimed to determine the factors associated with inadequate GWG and the characteristics of inadequate GWG based on the pre-pregnancy body mass index (BMI) among pregnant women in Japan. METHODS: This observational study included pregnant women at ≥16 weeks of gestation. The study was conducted at two general hospitals in Tokyo, Japan. The participants were requested to complete a questionnaire during the antenatal checkup visit and a mail survey after childbirth. Data were also collected from medical records. The GWG level and associated factors were assessed using the chi-square test or t-test. RESULTS: In total, 252 pregnant women were recruited and completed the questionnaires. Data from 128 pregnant women were analyzed. Overall, 23 (18.0%) women were classified as having inadequate GWG. The factors associated with inadequate GWG were as follows: pre-pregnancy underweight, hospital admission owing to hyperemesis, low body esteem, high Edinburgh Postnatal Depression Scale score, low target GWG, more significant weight loss during pregnancy when compared with that pre-pregnancy, high maximum weight loss during pregnancy, delay in return to pre-pregnancy weight, lower birth weight, and inadequate GWG perception. Pregnant women with inadequate weight gain did not receive any medical advice to avoid being overweight but were rather advised to gain additional weight. CONCLUSION: Target GWG and low body esteem were associated with inadequate GWG and other factors that could be modified. Medical staff should focus on achieving the target GWG and improving the body appreciation level among pregnant women.

OBJECTIVE: To translate the Infant Breastfeeding Assessment Tool (IBFAT) into Japanese and confirm the reliability and validity of the Japanese version of IBFAT. DESIGN: The methodological study examining the reliability and validity of the Japanese version of the IBFAT. SETTING: A maternity hospital in Tokyo. PARTICIPANTS: Ten mother-newborn pairs were recruited for the reliability analysis. 101 mother-newborn pairs were recruited for the validity analysis. MEASUREMENTS AND FINDINGS: Reliability was verified by video recording and direct observation. The observers are one researcher, and 11 evaluators consisting of midwives and nurses. Amongst the 11 evaluators, six evaluators directly observed breastfeeding behaviours and five evaluators observed breastfeeding behaviours through video viewing. Regarding the inter-rater agreement, the intraclass correlation (ICC) between the researcher and six direct evaluators was 0.985 (95% confidence interval [CI]: 0.941-0.996) and that amongst five video viewing evaluators was 0.827 (95% CI: 0.647-0.945). In the intra-rater agreement, the lowest ICC amongst all those investigating IBFAT scores was 0.810 (95% CI: 0.433-0.948). In concurrent validity, the correlation coefficients between the IBFAT and Breastfeeding behaviour Assessment (BBA) scores on the first day after birth and the fourth or fifth day after birth (at discharge) were 0.66 (p < 0.001) and 0.40 (p < 0.001), respectively. In predictive validity, the medians and interquartile ranges (IQRs) of IBFAT scores at discharge were 11.0 (IQR: 11.0-12.0) and 11.0 (IQR: 11.0-12.0) for the breast and mixed milk groups at one-month check-up, respectively. While both median values were the same, the Mann-Whitney U test showed a significant difference. KEY CONCLUSIONS: The Japanese version of the IBFAT is valid and reliable for measuring feeding behaviour amongst newborns in the first week of life. IMPLICATIONS FOR PRACTICE: The Japanese version of the IBFAT can be available both in a clinical setting and in research to help support breastfeeding.

Infantile skin problems not only cause temporary pain and discomfort, but also have a long-term impact on health. Hence, the purpose of this cross-sectional study was to clarify the relationship between inflammatory cytokines and Malassezia fungal facial skin problems in infants. Ninety-six 1-month-old infants were examined. Facial skin problems and the presence of inflammatory cytokines in the forehead skin were assessed using the infant facial skin visual assessment tool (IFSAT) and the skin blotting method, respectively. Malassezia, a fungal commensal, was detected using forehead skin swabs, and its percentage in the total fungal population was analyzed. Infants with positive interleukin-8 signals were more likely to have severe facial skin problems (p = 0.006) and forehead papules (p = 0.043). No significant association between IFSAT scores and Malassezia was found, but infants with forehead dryness had a lower percentage of M. arunalokei in the total fungal population (p = 0.006). No significant association was observed between inflammatory cytokines and Malassezia in the study participants. Longitudinal studies on the development of facial skin problems in infants are warranted to investigate the involvement of interleukin-8 and devise preventive strategies in the future.

BACKGROUND: Severe infant eczema on the face should be treated early because it may lead to allergic diseases in the future. However, caregivers find it difficult to assess. A visual tool for caregivers is needed to easily determine infants' facial skin condition severity based on the tool's scores. We developed an infant facial skin assessment tool (IFSAT) and evaluated its reliability and validity. METHODS: The IFSAT draft was developed based on results of a previous literature review and qualitative sketch. Panels including medical professionals and a caregiver checked the draft's content and face validity, and the IFSAT was finalized. To test the IFSAT's reliability and validity, caregivers and one-month-old infants were recruited. Two scoring methods were additionally created based on the relation between the items and cure period. The relationships between scores and cure period, and the ability to predict whether the infant needed medical treatment were examined by each scoring method. For the predictive validity, scores for infants requiring medical treatment and those for infants who did not were also compared. For the intra-examiner reliability analysis, two pediatricians rated the scores separately twice using photographs. Inter-rater reliabilities were analyzed among pediatricians, nurses, and caregivers. RESULTS: Altogether, 113 infant-caregiver pairs participated in the testing phase. Of the two scoring methods created (versions 1 and 2), pediatricians' and caregivers' scores using versions 1 and 2 were related to the cure period. These scores predict whether the infant needed medical treatment. We then selected version 2 based on the medical professionals' opinions. The scores of caregivers of infants requiring medical treatment were higher than those of caregivers of infants not requiring treatment (p < 0.001). The intraclass correlation coefficient (ICC) of intra-examiner reliability was 0.87. The ICC of inter-rater reliabilities between pediatricians' and caregivers' scores and between nurses' and caregivers' scores were 0.66, and 0.66, respectively. CONCLUSIONS: The proposed IFSAT may be used to assess whether infants need medical treatment and whether to extend the cure period. The tool's reliability and validity were confirmed.

AIM: Prolonged diaper dermatitis may increase the risk of atopic dermatitis or infections. This prospective observational study aimed to investigate the prevalence, symptoms, areas, and recovery time of diaper dermatitis in infants aged 1 month and identify the factors related to recovery time. METHODS: Diaper dermatitis was defined as the presence of erythema, papules, dryness, erosion, or ulceration in the diapered area. Recovery time was days between infant's 1-month medical check-up and disappearance of symptoms. Survival analysis was performed using the Kaplan-Meier method, and the log-rank test was used to identify the factors related to recovery time. RESULTS: Among 113 infants, 66 (58.4%) had diaper dermatitis, with erythema at the perianal area being the most common symptom. The median recovery time was 10 days. Four infants (6.1%) had diaper dermatitis for >5 weeks. Severity was not related to recovery time. CONCLUSIONS: A frequency of diaper changing of ≤10 times per day was a risk factor for recovery time. Our data showed recovery in approximately 10 days, regardless of severity at study enrollment. Health care professionals could inform parents of recovery time and recommended diaper changing frequency.

Objective: The aim of this study was to identify factors associated with requiring surgical treatment for mastitis or breast abscess in postpartum mothers. Materials and Methods: This was a retrospective cohort study using the Japan Medical Data Center Claims Database. Information on pairs of infants born between April 2012 and December 2016 and their mothers were extracted. Data regarding the baseline characteristics, medical history, medical practice, and prescription drugs of mothers and their infants were collected. Multivariable logistic regression analysis was used to examine factors associated with undergoing surgical treatment. Results: The data of 69,363 eligible mothers were analyzed. The proportion of mothers who were diagnosed with mastitis or breast abscess within 1 year after childbirth was 10.8% (7,516/69,363). There were 114 mothers who underwent surgical treatment within 1 year after childbirth. This was 0.2% of all mothers and 1.5% of those diagnosed with mastitis or breast abscess. Surgical treatment was significantly associated with mothers having their first child (adjusted odds ratio [AOR], 2.58; 95% confidence interval [CI], 1.63-4.07) compared to those with a second or later child; it was also significantly associated with the diagnosis of breast abscess (AOR, 10.38; 95% CI, 5.28-20.40). Conclusions: This was the first report of the prevalence of mastitis or breast abscess and the requirement for surgical treatment among postpartum mothers in Japan. A first diagnosis of breast abscess and having a first child were associated with requiring surgical treatment. Health care professionals providing postpartum care should be aware of these factors.

AIM: This study aimed to examine newborn-oriented and environmental factors of newborn skin barrier functions. METHODS: This was a retrospective secondary analysis of 227 newborns from a previous study. Newborn skin barrier functions were measured on the fourth day after birth via the following parameters: stratum corneum hydration, transepidermal water loss, skin pH, and sebum secretion. Skin barrier functions were measured at four body sites; their averaged values were used for the analysis. The associations among skin barrier functions, newborn-oriented factors, and environmental factors were evaluated. Multiple regression analysis was performed using a forced entry method, and independent variables for which p-values were <.05 in Student's t test, analysis of variance, and Pearson's correlation analysis were included. RESULTS: A total of 211 participants were analyzed. The mean ± standard deviation values of stratum corneum hydration, transepidermal water loss, skin pH, and sebum secretion were 28.58 ± 8.40 and 7.28 ± 2.02 g/m2 /h, 5.77 ± 0.53, and 23.59 ± 15.89 µg/cm2 , respectively. Newborn-oriented factors (gestational days, weight, amount of vernix, and parity) and environmental factors (birth season) were significantly associated with one or more skin barrier functions. CONCLUSIONS: Newborn-oriented (including labor- and delivery-related) and environmental factors were associated with the skin barrier functions. The newborn maturity level, newborn sex, environmental temperature, and humidity may affect skin barrier functions in newborns. Further studies should focus on the effects of these factors on newborn skin barrier assessments, and develop tailored skincare strategies based on their characteristics.

AIM: This study aimed to identify the relationship between the skin barrier function after bathing at 2 weeks of age and subsequent facial skin problems during the first 6 weeks of life. METHODS: A prospective observational study was conducted from July 2017 to February 2018 on healthy newborns aged 2 weeks. Skin barrier function was evaluated before bathing and at 30 and 90 min after bathing by measuring transepidermal water loss (TEWL), stratum corneum hydration (SCH), sebum secretion, and skin pH. Infantile facial skin problems were assessed using skin condition diaries maintained by a parent for 4 weeks. RESULTS: Analysis of the data from 56 infants showed that 29 infants (51.8%) experienced facial skin problems from 2 to 6 weeks of age. A lesser change in the sebum secretion on the forehead before bathing to 90 min after bathing and a higher SCH of the forehead before bathing were less likely to result in facial skin problems (adjusted odds ratio [AOR] = 0.98, 95% confidence interval [CI]: 0.97-0.99; AOR = 0.96, 95% CI: 0.92-0.99). CONCLUSIONS: A greater change in the sebum secretion on the forehead before bathing to 90 min after bathing and a lower SCH of the forehead before bathing were associated with subsequent infantile facial skin problems, indicating that a better ability to recover after bathing is important to prevent facial skin problems. Future studies should identify factors that enhance the recuperative functions of infantile skin.
RESUMEN
Objective: The objective of this study is to determine the factors associated with time spent performing housework/childcare by fathers of children under 12 years of age (preschool and elementary school children) in Japan. Methods: An online survey of employees and employers was conducted in 2017. Of the 7,796 total responses to the survey, those of 621 fathers of children aged 0-12 years were analyzed. Participants were divided into two groups: fathers of children aged 0-6 years, and fathers of children aged 7-12 years. Multiple logistic regression analysis was performed on the items for which there was a significant intergroup difference, setting time spent performing housework as the dependent variable and the survey items as the independent variables. Results: For fathers of children aged 0-6 years, working 40 hours or less per week and commuting for one hour or less were associated with more time spent performing housework/childcare. For fathers of children aged 7-12 years, working less than 40 hours a week, working from home more than once a week, and having spouses with full-time jobs were associated with more time spent performing housework/childcare. Conclusion: This study revealed the factors associated with the time spent by fathers of children under 12 in performing housework/childcare. As several of these factors cannot be altered by the fathers' efforts alone, companies and society in general must endeavor to improve work styles to better suit the habits and preferences of fathers. This will promote work-life balance and create better family relationships.
RESUMEN
In Mongolia, cardiovascular disease is the leading cause of death, and prevalence of hypertension is very high. The aim of this study was to investigate the association between hypertension and sociodemographic factors and health-related behaviors among men in Darkhan-Uul Province, Mongolia. This cross-sectional study was conducted between November 2015 and January 2016. Men whose wives were pregnant with ≤ 20 weeks gestation and had attended antenatal health checkups at public health facilities were recruited in this study. The data were collected as part of a survey of pregnant women and their partners. Data were collected using self-administered questionnaires, anthropometry, and spot urine samples. A total of 224 men participated in the survey, and data from 209 participants were included in the analysis. Multiple logistic regression analysis showed that men with higher BMI had higher odds of hypertension than those with lower BMI (adjusted odds ratio [AOR]: 1.14, 95% CI: 1.03-1.26). Those with urinary cotinine > 100 ng/ml (smokers) had a lower risk of hypertension (AOR: 0.24, 95% CI: 0.09-0.67) compared to participants with urinary cotinine/ml (nonsmokers). This is the first study to investigate the association between hypertension and sociodemographic factors and health-related behaviors among men in Mongolia. Based on the findings of this study, clinicians responsible for public health in Mongolia should provide health education regarding the importance of weight control in preventing hypertension.
RESUMEN
The issue of anemia is important in terms of a woman's preconception health. This study aimed to conduct an exploratory investigation of the prevalence of and factors related to anemia in non-pregnant Japanese women. Secondary data analysis was conducted using a database of women aged 20-49 years old who had attended an annual health check-up at a hospital in Tokyo (n = 10,598). A multiple logistic regression analysis was performed to identify factors related to anemia in two age groups: women aged 34 and under and those aged 35 and over. Anemia was defined as hemoglobin concentration levels <12.0 g/dL. The overall proportion of women with Hb <12.0 g/dL was 17.1%. Women aged 35 and over with a current medical history of uterine myoma were found to be at a higher risk of anemia. Women aged 35 and over who were overweight had a lower risk of anemia than women with normal weights. Current and past smoking habits affected hemoglobin levels among women aged 35 and over. In both age groups, those who drank alcohol habitually were at a lower risk than those who did not. Related factors of anemia should take into consideration a woman's age and lifestyle.

More than half of women are reported to be overweight or obese in Mongolia, thus becoming a big health issue. Though maternal obesity is a known risk factor for cesarean section (CS), it remains unclear how much a high maternal body mass index (BMI) would influence the risk of CS among pregnant women in Mongolia. This study aimed to investigate whether a higher maternal BMI is related to CS delivery in Darkhan-Uul Province, Mongolia. Pregnant women at 20 weeks' gestation or less who visited public health facilities for antenatal health checkups between November 2015 and January 2016 were recruited. Data were collected using self-administered questionnaires, body weight measurement, and medical records. In total, 508 pregnant women participated, and data from 336 women were analyzed. Multiple logistic regression analysis showed that higher maternal BMI at first antenatal care visit (adjusted odds ratio [AOR] = 1.102, p = .033), higher gestational weight gain (AOR = 1.111, p = .001), older maternal age (AOR = 1.076, p = .030), and gestational age at delivery (AOR = 0.765, p = .005) were associated with CS delivery. This study is the first to demonstrate that higher maternal BMI and higher gestational weight gain are associated with CS delivery in Mongolia. Moreover, older maternal age and lower gestational age at delivery were found to be associated with CS delivery. Preventing obesity among women is important not only from the viewpoint of prevention of lifestyle diseases but also from the obstetric point of view; it is important for medical personnel to communicate the importance of preventing obesity to all women in Mongolia.
RESUMEN
This study aimed to compare knowledge about smoking, including passive smoking, and urinary cotinine (UC) levels in pregnant women and their partners in Mongolia. The study was conducted between November 2015 and January 2016 in Darkhan-Uul Province, Mongolia. Pregnant women with less than 20 weeks' gestation were recruited, and their partners were also invited to participate. Self-administered questionnaires and urine samples were used to collect data. Knowledge about smoking including passive smoking was measured using 14 questions. Data were analyzed using a Student's t-test, a chi-squared test, a one-way analysis of variance, and the Tukey-Kramer method for post-hoc analysis. Correlations were measured by computing Pearson's r or Spearman's ρ. A total of 508 pregnant women and 227 partners participated in this study; of these, 221 couples' data were analyzed. Pregnant women's scores on knowledge about smoking and passive smoking were significantly higher than those of their partners (9.4 ± 2.9 and 8.7 ± 3.1, respectively; p = 0.017). Pregnant women's and their partners' scores were slightly correlated (r = 0.163, p = 0.015). Pregnant women's and their partners' UC levels were significantly correlated (ρ = 0.250, p < 0.001). This study is the first to examine knowledge about smoking and passive smoking and UC levels among pregnant women and their partners in Mongolia. Because pregnant women's and their partners' scores and UC levels were positively correlated, health education on the harm caused by smoking and passive smoking should be provided to both pregnant women and their partners.
RESUMEN
This cross-sectional study investigated the prevalence of smoking and secondhand smoking (SHS) among pregnant women in Darkhan-Uul Province, Mongolia, using urinary cotinine (UC) levels, and clarified the factors related to SHS exposure. It targeted pregnant women who underwent antenatal health check-ups from November 2015 to January 2016. Self-administered questionnaires and urine samples were used to collect data. Using UC levels as the criterion, it was found that the prevalence of smokers (>100 ng/ml) among 493 pregnant women was 11.8%, while SHS exposure (≥5 ng/ml) among nonsmokers was 44.8%. Older and highly educated women had lower odds of SHS exposure (p = 0.006 and 0.002, respectively). Furthermore, nonsmoking pregnant women from homes where smoking was permitted had higher odds of SHS exposure compared to women from homes where smoking was not permitted. These results suggest that community guidance programs, such as home smoking cessation that include families, are necessary.

To estimate the incidence (any mother to child) and rate (from seropositive mother to child) of mother-to-child transmission of Trypanosoma cruzi, a serological census was conducted, targeting pregnant women and infants born to seropositive mothers, in four municipalities of El Salvador. Of 943 pregnant women, 36 (3.8%) were seropositive for T. cruzi. Of 36, 32 proceeded to serological tests of their infants when they became 6-8 months of age. Six infants seropositive at the age of 6-8 months further proceeded to second-stage serological test at the age of 9-16 months. As the result, one infant was congenitally infected. Thus, serological tests at the age of 6-8 months produced five false positives. To ensure earlier effective medication only for true positives, identification of seropositive infants at the age of 9-16 months is crucial. Incidence and rate of mother-to-child transmission were 0.14 (per 100 person-years) and 4.0%, respectively. Estimated number of children infected through mother-to-child transmission in El Salvador (170 per year) was much higher than that of human immunodeficiency virus (HIV; seven per year). It is recommended that serological testing for T. cruzi be integrated into those for HIV and syphilis as part of antenatal care package.
