RESUMO
BACKGROUND: Designing competency-based education (CBE) programmes is a priority in global nursing education for better nursing care for the population. In the Democratic Republic of the Congo (DRC), object-based education (OBE) remains mainstream in pre-service nursing education programmes. Recently, the Ministry of Health developed a self-assessment tool and quantitatively compared the clinical competency of CBE- and OBE-trained nurses. This study aimed to qualitatively triangulate the results of self-evaluation by exploring perception of supervisors, incumbent CBE-, and OBE-trained nurses in comparison with the competence of the two types of nurses, and to identify influential factors or barriers to their competence in clinical settings. METHODS: A qualitative descriptive approach with conventional content analysis was applied. Twenty interviews with clinical supervisors who oversaw both CBE- and OBE-trained nurses, 22 focus group discussions (FGDs) with CBE-trained nurses, and 21 FGDs with OBA-trained nurses currently working in health facilities were conducted. Participants of the FGDs were selected from the participants of the DRC self-assessment competency comparison study where there was no statistically significance between CBE- and OBE-trained nurses in the demographic characteristics. Data were analysed in terms of the competencies identified by the Ministry of Health. RESULTS: The supervisors recognised that the CBE-trained nurses had stronger competencies in professional communication, making decisions about health problems, and engaging in professional development, but were weak in clinical skills. This study identified challenges for supervisors in assuring standardised care in health facilities with OBE- and CBE-trained nurses, as well as barriers for CBE-trained nurses as a minority in the workplace in demonstrating their competencies. CONCLUSIONS: The study results support the Ministry of Health's policy to expand CBE in pre-service education programmes but reveal that its slow implementation impedes full utilisation of the acquired competencies at health facilities. Implementation could be accelerated by strengthening cooperation among the Ministry of Health's three human resource departments, and developing and implementing a well-planned, legally binding, long-term CBE reform strategy, including an approach to the Continuing Professional Development system.

BACKGROUND: Ministries of health in collaboration with the World Health Organization Regional Office for the Western Pacific (WPRO) have been scaling up early essential newborn care (EENC). This study was carried out to understand current EENC practices at hospitals in two priority countries: the Kingdom of Cambodia (Cambodia) and Lao People's Democratic Republic (Lao PDR). METHODS: EENC is subdivided into 79 checkpoints, referencing the self-monitoring checklist developed by the WPRO. Each checkpoint is rated using a 0 to 2-point scale, and a percentage was calculated for the rate of practice of each checkpoint by dividing the total scores by the maximum possible scores. RESULTS: In total, 55 and 56 deliveries were observed in Cambodia and Lao PDR, respectively, and 35 and 34 normal deliveries were included in the analysis. The overall rates of the practices within the first 15 minutes after birth were high in both countries. The rates of the practices before birth and 15 minutes after birth were lower than the rates of the practices performed within the first 15 minutes after birth, especially "hand wash before preparation", "preparation for newborn resuscitation", and "monitoring of postpartum mothers and babies". A detailed analysis revealed that the quality of the practices differed between the two countries regarding skin-to-skin contact and breastfeeding support. CONCLUSIONS: The high rates of the practices within the first 15 minutes after birth suggest that the EENC coaching sessions supported by ministries of health and the WPRO have been effective. Differences in the quality of practices performed at a high rate between the two countries appeared to be related to factors such as the timing of the study, the perception of the staff, and the situation at the health facilities. These differences and identified practices with lower rates should be improved according to the situation in each country or health facility. Therefore, determining the quality of the practices in a country or a health facility is important. To further improve the quality of EENC, interventions tailored to the specific situation are necessary.

BACKGROUND: Health workers, the core of health service delivery and a key driver of progress towards universal health coverage, must be available in sufficient numbers and distributed fairly to serve the entire population. In addition, the planning and management of the health workforce must be responsive to the changing needs of society, including changes in age structure and epidemiology. Considering these issues, this paper examines in historical perspective the evolution of postgraduate medical training and practice in Japan, from the late nineteenth century to the present. MAIN TEXT: When the first medical schools were established in the country towards the end of the nineteenth century, Japan was a largely agrarian society, with a population of about 30 million and an average life expectancy of 30-40 years. During the twentieth century, life expectancy and the national population continued to increase in a context of rapid economic growth. Since the 1980s, another demographic transition has occurred: low fertility rates and an aging society. As a result, the inputs and skills required from health professionals have changed considerably over time, posing new challenges to the national health sector and the management of human resources for health. CONCLUSIONS: The case of Japan offers valuable lessons for other countries experiencing a rapid epidemiological and demographic transition. To provide medical care that meets health priorities in the communities, we must consider not only the training of specialists, but also ensure the availability of a large cadre of physicians who possess basic skills and can provide patient-centred care. Furthermore, the Japanese experience shows that a highly hierarchical system and organisational culture are ill-suited to respond quickly to the changing demands of society.

BACKGROUND: Child abuse and postnatal depression are two public health problems that often co-occur, with rates of childhood maltreatment highest during the first year of life. Internet-based behavioural activation (iBA) therapy has demonstrated its efficacy for improving postnatal depression. No study has examined whether the iBA program is also effective at preventing child abuse. This study aims to investigate whether iBA improves depressive symptoms among mothers and prevents abusive behaviours towards children in postpartum mothers in a randomized controlled trial, stratifying on depressive mood status. The study also evaluates the implementation aspects of the program, including how users, medical providers, and managers perceive the program in terms of acceptability, appropriateness, feasibility, and harm done. METHODS: The study is a non-blinded, stratified randomized controlled trial. Based on cut-off scores validated on Japanese mothers, participants will be stratified to either a low Edinburgh Postnatal Depression Scale (EPDS) group, (EPDS 0-8 points) or a high EPDS group (EPDS ≥9 points). A total of 390 postnatal women, 20 years or older, who have given birth within 10 weeks and have regular internet-access will be recruited at two hospitals. Participants will be randomly assigned to either treatment, with treatment as usual (TAU) or through intervention groups. The TAU group receives 12 weekly iBA sessions with online assignments and feedback from trained therapists. Co-primary outcomes are maternal depressive symptoms (EPDS) and psychological aggression toward children (Conflict Tactic Scale 1) at the 24-week follow-up survey. Secondary outcomes include maternal depressive symptoms, parental stress, bonding relationship, quality of life, maternal health care use, and paediatric outcomes such as physical development, preventive care attendance, and health care use. The study will also investigate the implementation outcomes of the program. DISCUSSION: The study investigates the effectiveness of the iBA program for maternal depressive symptoms and psychological aggression toward children, as well as implementation outcomes, in a randomized-controlled trial. The iBA may be a potential strategy for improving maternal postnatal depression and preventing child abuse. TRIAL REGISTRATION: The study protocol (issue date: 2019-Mar-01, original version 2019005NI-00) was registered at the UMIN Clinical Trial Registry (UMIN-CTR: ID UMIN 000036864 ).

We examined whether alanine aminotransferase/aspartate aminotransferase (ALT/AST), a marker of hepatosteatosis, may be associated with a wider constellation of variables related to metabolic syndrome in Japanese women. Body fat and distribution, and metabolic syndrome-related variables were measured in 311 young and 148 middle-aged women. We had Pearson's correlation analysis and then stepwise multivariate linear regression analyses. In both middle-aged and young women, ALT/AST was associated with homeostasis model assessment insulin resistance (HOMA-IR), trunk/leg fat ratio and pulse rate. In middle-aged women but not in young women, ALT/AST was associated with waist circumference, fasting glucose, triglyceride, HDL cholesterol (inversely), systolic, diastolic and mean blood pressure (BP). Further, in middle-aged women only, the ratio was associated with BMI, percentage body fat, apolipoprotein B and plasminogen activator inhibitor-1. Among these variables, pulse rate in young women and systolic BP in middle-aged women were associated with ALT/AST independently of trunk/leg fat ratio, a sophisticated measures of abdominal fat accumulation,ãHOMA-IR, fasting glucose, triglyceride and HDL cholesterol. In conclusion, ALT/AST was associated with pulse rate in young women and with systolic BP in middle-aged women independently of abdominal fat accumulation and insulin resistance. It is noted that their waist circumference averaged < 80 cm and ALT < 30 U/L, suggesting minimum accumulation of abdominal and hepatic fat, respectively, key drivers of insulin resistance and metabolic syndrome.

RESUMO
Normal-weight but high-percentage trunk fat phenotype was characterized in a setting where adiposity is not associated with educational and socioeconomic status. Body size trajectory since birth, current body composition measured using whole-body dual-energy X-ray absorptiometry, cardiometabolic traits, serum adipokines, and dietary intake were measured cross-sectionally in 251 normal weight Japanese female university students whose fasting triglyceride and homeostasis model assessment-insulin resistance (HOMA-IR) averaged 56 mg/dL and 1.2, respectively. They were grouped according to tertile of percentage trunk fat. Although HOMA-IR did not differ among three groups, high-percentage trunk fat was associated with higher triglyceride and apolipoprotein B, and lower HDL cholesterol and apolipoprotein A1. In multivariate logistic regression analyses, weight-adjusted skeletal muscle mass (OR: 0.13, 95% CI: 0.04-0.38, p < 0.001), weight gain from birth to age 12 years (OR: 1.214ã95% CI: 1.008-1.463ãp = 0.04), and cereal consumption (OR:1.008, 95% CI: 1.000-1.016, p = 0.04) were associated with high-percentage trunk fat independent of birthweight, HOMA-IR, adipose tissue-insulin resistance index (the product of fasting insulin and free fatty acid), triglyceride, HDL cholesterol, apolipoprotein A1 and B, leptin, adiponectin, blood pressure, and high-sensitivity C-reactive protein. Early childhood growth, lower skeletal muscle mass, and higher cereal consumption may be associated with normal-weight but high-percentage trunk fat phenotype in Japanese female university students in this subanalysis study. Atherogenic profile of lipids and apolipoproteins may be directly related to abdominal fat accumulation.
RESUMO
Aim: Associations of the adipose tissue insulin resistance index (AT-IR, a product of fasting insulin and free fatty acid) with body fat distribution and the ratio of alanine to aspartate aminotransferase (ALT/AST), a marker of hepatosteatosis, were examined in the context of the metabolic syndrome. Methods: Legs, the trunk and body fat by DXA, blood pressure (BP) and blood chemistry were measured in 284 young Japanese female university students and 148 middle-aged biological mothers whose BMI averaged <23 kg/m2. Results: Young women had higher leg fat/body fat and lower trunk fat/body fat ratio (both p < 0.001) compared with middle-aged women but AT-IR did not differ between the two groups. We had multivariable linear regression analysis for AT-IR as a dependent variable including leg fat/body fat ratio, trunk fat/body fat ratio, fasting glucose, triglyceride, HDL cholesterol and systolic BP as independent variables. Leg fat/body fat ratio, fasting glucose and triglyceride (p = 0.013, 0.009 and 0.016, respectively) emerged as determinants of AT-IR in young women. Trunk fat/body fat ratio and fasting glucose (p = 0.003 and 0.019, respectively) emerged in middle-aged women. In a model which included ALT/AST as an additional independent variable, ALT/AST (p = 0.016) was the fourth independent determinant in young women and the single determinant of AT-IR in middle-aged women (p < 0.001). Conclusion: In young Japanese women, adipose tissue insulin resistance was associated with reduced leg fat, a subtle partial lipodystrophy-like phenotype associated with reduced adipose tissue expandability. It was associated with elevated trunk (abdominal) fat in middle-aged women and with ALT/AST, a marker of hepatosteatosis, in two groups of Japanese women, suggesting ectopic fat deposition associated with reduced adipose tissue expandability.
RESUMO
Associations of adipose tissue insulin resistance index (AT-IR, a product of fasting insulin and free fatty acids) with body fat mass and distribution and appendicular skeletal muscle mass (ASM) were compared with results of homeostasis-model assessment-insulin resistance (HOMA-IR) in 284 Japanese female university students and 148 their biological mothers whose BMI averaged < 23 kg/m2. Although mothers compared with daughters had higher BMI, body fat percentage, trunk fat to body fat (TF/BF) ratio and lower leg fat to body fat (LF/BF), AT-IR and HOMA-IR did not differ. We had multivariable linear regression analyses which included TF/BF ratio, LF/BF ratio, weight-adjusted ASM (%ASM), height-adjusted ASM index (ASMI), fat mass index (FMI), and body fat percentage. In young women, AT-IR was independently associated with LF/BF ratio (Standardized ß [Sß]: - 0.139, p = 0.019) and ASMI (Sß: - 0.167, p = 0.005). In middle-aged women, LF/BF ratio (Sß: - 0.177, p = 0.049) and %ASM (Sß: - 0.205, p = 0.02) emerged as independent determinants of AT-IR. HOMA-IR was associated with TF/BF ratio and FMI, a proxy of abdominal and general adiposity, respectively, in both young and middle-aged women. The inverse association of AT-IR with leg fat may support the notion that limited peripheral adipose storage capacity and small skeletal muscle size are important etiological components in insulin-resistant cardiometabolic disease in Japanese women.

The present study investigated the associations of serum gamma-glutamyl transferase (GGT), a marker of fatty liver and oxidative stress, and ALT/AST, a marker of fatty liver, with percentage trunk fat and postload glucose, insulin resistance, and ß-cell function in middle-aged Japanese individuals, whose BMI averaged < 23.0 kg/m2. Pancreatic ß-cell function was assessed using the disposition index calculated by a product of the insulinogenic index (IGI) and Matsuda insulin sensitivity index, a biomarker of early-phase glucose-stimulated insulin secretion and whole-body insulin sensitivity, respectively. Multivariate linear regression analyses revealed that the disposition index was associated inversely with GGT independently of percentage trunk fat, homeostasis model assessment insulin resistance (HOMA-IR), a marker of insulin resistance, and Matsuda index. When IGI was included instead of the disposition index, IGI (inversely) and HOMA-IR were associated with GGT independently of percentage trunk fat and Matsuda index. When the area under the glucose concentration curve (AUCg) during an oral glucose tolerance test was included instead of the disposition index, AUCg and HOMA-IR emerged as independent determinants of GGT. ALT/AST was associated with HOMA-IR alone. Results suggest a different pathophysiologic basis between GGT and ALT/AST in predicting diabetic risk in non-obese Japanese.

Aim: We tested whether skeletal muscle mass is associated with insulin sensitivity, pancreatic ß-cell function, and postglucose glycemia. Methods: Appendicular skeletal muscle mass (ASM) (relative to body size, %ASM) by DXA, surrogate measures of insulin sensitivity, insulin secretion and the disposition index (insulin sensitivity adjusted insulin secretion: a product of the insulinogenic index and Matsuda insulin sensitivity index) inferred from serum insulin kinetics during a 75 g oral glucose tolerance test (OGTT) were evaluated in 168 young and 65 middle-aged women, whose BMI averaged <23.0 kg/m2 and HbA1c ⦠5.5 %. Results: In two groups of women, %ASM was associated negatively with homeostasis model assessment insulin resistance (HOMA-IR) and 2-h insulin (both p < 0.01 or less). In middle-aged women not in young women, %ASM was associated inversely with the Matsuda index (p < 0.001). In middle-aged women only, it also showed a positive association with the disposition index (p = 0.02) and inverse associations with 1-h and 2-h glucose (both p < 0.01) and area under the glucose concentration curve during OGTT (p = 0.006). On multivariate linear regression analyses, 2-h insulin emerged as a determinant of %ASM independently of HOMA-IR in young women (standardized ß: 0.287, p < 0.001, R2 = 0.077). In middle-aged women, the Matsuda index emerged as a determinant of %ASM (standardized ß: 0.476, p < 0.001) independently of HOMA-IR, log ODI and AUCg and explained 21.3 % of %ASM variability. Post-glucose glycemia and AUCg were higher and log ODI was lower in middle-aged women with low compared with high %ASM. Conclusion: Low skeletal muscle mass (relative to body size) was associated with low insulin sensitivity in young and middle-aged Japanese women who were neither obese nor diabetic. Middle-aged women with low muscle mass had low disposition index, an early marker of inadequate pancreatic ß-cell compensation, and hence high glucose excursion. Low skeletal muscle mass may be associated with the development of type 2 diabetes at a much lower BMI in Japanese people.
RESUMO
The relationship of adipose tissue insulin resistance (AT-IR, a product of fasting insulin and free fatty acids) and homeostasis-model assessment-insulin resistance (HOMA-IR) to ß-cell function was studied cross-sectionally in the setting of subtle glucose dysregulation. Associations of AT-IR and HOMA-IR with fasting and post-glucose glycemia and ß-cell function inferred from serum insulin kinetics during a 75 g oral glucose tolerance test were studied in 168 young female Japanese students. ß-cell function was evaluated by disposition index calculated as a product of the insulinogenic index (IGI) and Matsuda index. AT-IR, not HOMA-IR, showed positive associations with post-glucose glycemia and area under the glucose response curve although both indices were associated with fasting glycemia. HOMA-IR, not AT-IR, was associated positively with log IGI whereas both indices were inversely associated with Matsuda index. AT-IR, not HOMA-IR, showed inverse associations with log disposition index. Associations of adipose tissue insulin resistance with ß-cell function (inverse) and glucose excursion in young Japanese women may suggest that lipotoxicity to pancreatic ß-cells for decades may be associated with ß cell dysfunction found in Japanese patients with type 2 diabetes. Positive association of HOMA-IR with insulinogenic index may be associated with compensatory increased insulin secretion.

In the Democratic Republic of the Congo (DRC), the object-based approach (OBA) still remains mainstream in the basic nursing education program, despite the intention of the Ministry of Public Health to expand the competency-based approach (CBA) nationwide. This study aimed to compare the clinical competency of nurses trained with CBA and OBA. A cross-sectional, mixed study was conducted. We developed a self-assessment questionnaire consisting of an individual demographic information, a clinical competency assessment scale and the General Self-efficacy Scale. Nurses trained with CBA or OBA and currently working in health facilities with two to five years of clinical experience were purposively selected from ten cities across nine provinces in the DRC. We also conducted key informant interviews with the clinical supervisors at health facilities. In a comparison of 160 nurses trained with CBA and 153 with OBA, 3 competency domains ("establishing professional communication", "making decisions about health problems", and "performing nursing interventions") of the 5 domains required for nurses had significantly higher scores in the CBA group. The key informant interviews supported these results while revealing various issues in the basic nursing education program. The results support the strategic direction of the Ministry of Public Health in the DRC to expand CBA. Collaboration among education institutions, health facilities, and administrative bodies is crucial for clinical nurses to fully engage their competencies for the population. Other low- and middle-income countries with scarce resources can refer to the developed and implemented competency assessment method applied in this study.
RESUMO
Objective: We assessed whether alanine aminotransferase/aspartate aminotransferase (ALT/AST), a marker of hepatic steatosis, may be associated with adipose tissue dysfunction more closely than hepatic and muscle insulin resistance (IR). Methods: Associations with adipose tissue IR index (AT-IR) calculated as a product of fasting insulin and free fatty acids, leptin/adiponectin ratio, a proxy of adipocyte dysfunction, homeostasis model assessment IR (HOMA-IR), hepatic and muscle IR inferred from plasma insulin kinetics during a 75 grams oral glucose tolerance test (OGTT) were studied in nondiabetic 307 young and 148 middle-aged Japanese women, whose body mass index averaged 20 and 22 kilograms/m2, respectively. Results: On multivariate linear regression analysis in young women, ALT/AST was associated with trunk/leg fat ratio (standardized ß = 0.202, P = 0.007), a marker of abdominal fat accumulation, and AT-IR (standardized ß = 0.185, P = 0.003) independently of HOMA-IR and Matsuda index (R2 = 0.07). In middle-aged women, leptin/adiponectin ratio (standardized ß = 0.446, P < 0.001) and AT-IR (standardized ß = 0.292, P = 0.009) emerged as determinants of ALT/AST independently of trunk/leg fat ratio, OGTT-derived hepatic IR, leptin, and adiponectin (R2 = 0.34). Conclusions: ALT/AST was associated with AT-IR and adipocyte dysfunction more closely than hepatic and muscle IR even in nondiabetic lean Japanese women.

We tested whether alanine aminotransferase/aspartate aminotransferase (ALT/AST), a marker of hepatosteatosis, associates with insulin resistance, ß-cell function and postglucose glycemia. We studied 311 young and 148 middle-aged Japanese women, whose BMI averaged < 23.0 kg/m2. Insulinogenic index and Matsuda index were evaluated in 110 young and 65 middle-aged women. In two groups of women, ALT/AST was associated positively with homeostasis model assessment insulin resistance (HOMA-IR) and inversely with Matsuda index. In middle-aged women only, the ratio was also associated positively with fasting and postload glycemia and HbA1c. The ratio showed negative association with disposition index (a product of insulinogenic index and Matsuda index). On multivariate linear regression analysis, HOMA-IR emerged as a single determinant of ALT/AST in young and middle-aged women (standardized ß: 0.209, p = 0.003 and 0.372, p = 0.002, respectively). ALT/AST was associated with insulin resistance and ß-cell function even in non-obese Japanese women, suggesting a pathophysiologic basis in its prediction of diabetic risk.

Normal weight insulin resistant phenotype was characterized in 251 Japanese female university students using homeostasis model assessment-insulin resistance. Birth weight, body composition at age 20, cardiometabolic traits and dietary intake were compared cross-sectionally between insulin sensitive (< 1.6, n = 194) and insulin resistant (2.5 and higher, n = 16) women. BMI averaged < 21 kg/m2 and waist < 72 cm and did not differ between two groups. The percentage of macrosomia and serum absolute and fat-mass corrected leptin concentrations were higher in insulin resistant women although there was no difference in birth weight, fat mass index, trunk/leg fat ratio and serum adiponectin. In addition, resting pulse rate, serum concentrations of free fatty acids, triglycerides and remnant-like particle cholesterol were higher in insulin resistant women although HDL cholesterol and blood pressure did not differ. In multivariate logistic regression analyses, serum leptin (odds ratio:1.68, 95% confidential interval:1.08-2.63, p = 0.02) was associated with normal weight insulin resistance independently of macrosomia, free fatty acids, triglycerides, remnant-like particle cholesterol and resting pulse rate. In conclusion, normal weight IR phenotype may be associated with increased plasma leptin concentrations and leptin to fat mass ratio in young Japanese women, suggesting higher leptin production by body fat unit.

INTRODUCTION: Adipose tissue (AT) expandability may be facilitated by adiponectin and suppressed by orosomucoid, and reduced AT expandability may be associated with first-degree relatives of type 2 diabetes. We tested the hypothesis that orosomucoid may be associated not only with adiponectin and adipose tissue insulin resistance but also with a family history of type 2 diabetes (FHD). Research Design and Methods. Anthropometric and metabolic variables, adipokines, and measures of inflammatory and insulin resistance were cross-sectionally investigated in 153 young normal weight Japanese women. Stepwise multivariate linear regression analyses were used to identify the most important determinants of orosomucoid. RESULTS: Orosomucoid was higher in women with positive (n = 57) compared to women with negative FHD and was associated positively with FHD (both p = 0.01). Orosomucoid also showed positive associations with fasting glucose (p < 0.001), free fatty acids (p = 0.001), and HbA1c (p = 0.007), whereas there was no association with fasting insulin and serum lipids. In addition, orosomucoid was associated inversely with adiponectin (p = 0.02) and positively with adipose tissue-insulin resistance index (AT-IR, the product of fasting insulin and free fatty acids; p = 0.001) but not with homeostasis model assessment-insulin resistance, leptin, and high-sensitivity C-reactive protein. In multivariate analyses, AT-IR (standardized ß, 0.22; p = 0.003), serum adiponectin (standardized ß, -0.163; p = 0.032), FHD+ (standardized ß, 0.178; p = 0.029), and HbA1c (standardized ß, 0.213; p = 0.005) emerged as independent determinants of orosomucoid and explained 15.2% of its variability. CONCLUSIONS: These results are the first to demonstrate that orosomucoid is associated not only with adipose tissue-insulin resistance and adiponectin but also with FHD.

OBJECTIVE: We suggested association of family history of type 2 diabetes (FHD) with microvascular dysfunction, which may cause blood pressure (BP) elevations. We test whether FHD may be associated with higher BP. RESEARCH DESIGN AND METHODS: Resting BP, heart rates (in beats per minute: bpm), body composition and fasting concentrations of glucose, insulin, leptin and adiponectin were measured in 332 Japanese women aged 18-24 years. They were grouped according to BP category defined by the 2017 American College of Cardiology/American Heart Association Blood Pressure Guideline. RESULTS: BMI averaged < 22 kg/m2 and did not differ cross-sectionally between 73 with (FHD+) and 259 without FHD (FHD-). FHD+ had higher mean (81 ± 9 vs. 77 ± 7 mmHg, p < 0.001), systolic (111 ± 13 vs. 106 ± 10 mmHg, p = 0.003) and diastolic BP (65 ± 8 vs. 60 ± 7 mmHg, p < 0.001). Prevalence of elevated BP (11.0 vs. 6.2%), hypertension stage 1 (4.1 vs. 0.8%) and stage 2 (2.7 vs. 0.4%) was higher as well (p = 0.01). Endurance training in FHD+ abolished the differences in BP readings and BP prevalence. However, the mean resting heart rate in FHD+ athletes (61.2 bpm) was close to those in FHD+ (64.7 bpm) and FHD- nonathletes (64.6 bpm) and was higher than in FHD- athletes (56.5 bpm). Fat mass and distribution evaluated by dual-energy X-ray absorptiometry, markers of insulin resistance, and serum adipokines studied did not differ between the two groups. CONCLUSIONS: FHD was associated with higher BP and higher prevalence of elevated BP and hypertension, suggesting contribution of microvascular dysfunction in BP elevations in normal weight young Japanese women. FHD may be associated with reduced heart rate response to endurance training as well.
RESUMO
Objective: We examined whether elevated blood pressure (BP) (≥120/80 mmHg) was associated with several anthropometric, metabolic, and clinical variables, including the family history of type 2 diabetes (FHD) and low birth weight, in young normal weight Japanese women. Methods: BP, body composition, and fasting glucose, insulin, lipids, lipoproteins, apolipoproteins, and adipokines were measured in 332 young Japanese women. They received a questionnaire on birth weight and FHD. Results: The prevalence of low birth weight was 2.4% and that of positive FHD was 22.9%. Homeostasis model assessment-insulin resistance averaged <1.5 and did not differ cross-sectionally between 32 women with elevated BP and 300 women with normal BP although mean body mass index was higher in the former than in the latter (21.7 ± 2.9 kg/m2 vs. 20.8 ± 2.2 kg/m2, P = 0.02). Women with elevated BP had higher fat mass index (P = 0.02) and trunk fat percentage (P = 0.04). They had lower high-density lipoprotein (HDL) cholesterol and apolipoprotein A1 (both P = 0.01) while fasting triglycerides and apolipoprotein B did not differ. In addition, they had higher plasminogen activator inhibitor-1 (PAI-1) (P = 0.001). Furthermore, the prevalence of low birth weight (9.4% vs. 1.7%, P = 0.03) and positive FHD (40.6% vs. 20.0%, P = 0.01) was higher in women with elevated BP. Multivariable logistic regression analyses revealed that elevated BP was independently associated with PAI-1 [odds ratio (OR); 1.05, 95% confidence interval (CI): 1.02-1.08, P = 0.001], low birth weight (OR: 12.3, 95% CI: 2.3-67.3, P = 0.04), and FHD (OR: 3.0, 95% CI: 1.3-7.9, P = 0.01). Conclusion: Elevated BP was associated with positive FHD, low birth weight, and elevated serum PAI-1 in young normal weight Japanese women.

Introduction: We studied weight trajectory since birth and dietary intake in Japanese female students majoring in nutrition sciences. Materials and Methods: Birth weight, adolescent height and weight, current body composition by whole-body dual-energy X-ray absorptiometry, dietary intake, glucose tolerance, lipid profile, and adipokines were cross-sectionally compared between young underweight (body mass index [BMI] <18.5) and normal-weight (BMI ≥18.5 and <25.0) women with overweight (BMI ≥25.0) women as an internal reference. Results: Serum adiponectin (leptin) was the highest (lowest) in 42 underweight women, intermediate levels in 251 normal-weight women, and the lowest (highest) levels in 14 overweight women. Compared with normal-weight women, underweight women had lower weight at birth, at age 12, 15, and 20 years, but comparable height, and hence lower BMI at three time points. Underweight women had higher gluteofemoral fat adjusted for total body fat and weight-adjusted skeletal muscle mass, although absolute and height-adjusted fat mass and skeletal muscle mass were lower. Glucose tolerance assessed by oral glucose testing, serum triglycerides, and high-density lipoprotein cholesterol did not differ between the two groups. Daily intake expressed per kg of body mass of energy and protein was the highest in underweight women, intermediate levels in normal-weight women, and the lowest levels in overweight women. Conclusions: Some young Japanese women are underweight not because of a strong drive for thinness, but because they were born lighter and remained lean until young adults. Underweight was associated with higher gluteofemoral fat adjusted for total body fat and relative skeletal muscle mass.
RESUMO
INTRODUCTION: Adipose insulin-resistant but normal weight phenotype has not been reported and hence was characterized in young Japanese women. RESEARCH DESIGN AND METHODS: Body composition, a broad range of cardiometabolic health and dietary intake were cross-sectionally measured in 166 normal weight young Japanese women. They were grouped into tertile of adipose tissue-insulin resistance (AT-IR) index (fasting insulin×free fatty acids) and analyzed by analysis of variance and then Bonferroni's multiple comparison procedure. RESULTS: Body mass index averaged <21 kg/m2 and waist <72 cm, and did not differ among three groups of women. Fasting glucose and triglycerides and homeostasis model assessment-insulin resistance were higher in the highest compared with the median and lowest AT-IR tertile. However, there was no difference in fat mass and distribution, high-density lipoprotein cholesterol and blood pressure. In addition, high-sensitivity C reactive protein (hsCRP) and resting pulse rate were higher as well. In multivariate logistic regression analyses, fasting glucose (OR: 1.10, 95% CI: 1.02 to 1.18, p=0.012), fasting triglycerides (OR: 1.04, 95% CI: 1.02 to 1.06, p<0.001), resting pulse rate (OR: 1.07, 95% CI: 1.03 to 1.11, p<0.001) and hsCRP (OR: 2.30, 95% CI: 1.01 to 5.2, p=0.04) were associated with the high AT-IR tertile. CONCLUSIONS: Adipose insulin-resistant but normal weight phenotype may be associated with increased sympathetic nervous system and low-grade systemic inflammation in addition to glucose and lipid dysmetabolism through mechanisms unrelated to adiposity in young Japanese women.
