RESUMO
BACKGROUND: The formation of macrosomia is associated with excessive nutrition and/or unable to regulate effectively. This case-control study aims to explore the relationship between macrosomia and glucose, lipids and hormones levels in maternal and cord serum. METHODS: In the case-control study, 78 pairs of mothers and newborns were recruited who received care at one hospital of Hebei, China between 2016 and 2019. According to the birth weight (BW) of newborns, participants were divided into macrosomia group (BW ≥ 4000 g, n = 39) and control group (BW between 2500 g and 3999 g, n = 39). Maternal vein blood and cord vein blood were collected and assayed. All data were compared between the two groups. Unconditional logistics regression analysis was used to test the relationship between macrosomia and glucose, lipids and hormones in maternal and cord serum. RESULTS: In maternal and cord serum, the levels of leptin, leptin/adiponectin ratio (LAR), glucose and triglyceride (TG) in macrosomia group were higher than those in control group, and the levels of high-density lipoprotein cholesterol (HDL-C) were lower. The percentage of maternal glucose and lipids transfer to cord blood did not differ between the two groups. High levels of TG in maternal serum were positively correlated with macrosomia, and high levels of LAR, TG and glucose in cord serum were positively correlated with macrosomia. CONCLUSION: In conclusion, the results of the current study, suggest that the nutrients and metabolism-related hormones in maternal and umbilical cord are closely related to macrosomia. During pregnancy, the nutritional status of pregnant women should be paid attention to and to obtain a good birth outcome.

BACKGROUND: Sternum and rib fractures represent a significant global health concern, contributing to morbidity and disability on a worldwide scale. However, there is a notable lack of recent epidemiological data detailing the global and regional burden of these fractures. METHODS: We undertook a systematic analysis of the prevalence of sternum and rib fractures at the global, regional, and national levels in 2019, while also examining time trends spanning from 1990 to 2019. To achieve this, we extracted data from the Global Burden of Disease Study 2019, enabling us to determine incidence, prevalence, years lived with disability (YLDs), and their corresponding age-standardized rates. RESULTS: In 2019, there were 4.1 million incident cases and 2 million prevalent cases of sternum and rib fractures worldwide. These figures represent increases of 43.7 % and 64.1 %, respectively, since 1990. YLDs also exhibited a notable increase, rising by 62.4 % to reach 190,834 cases. However, since 1990, their equivalent age-standardized rates, which ranged from 5.5 % to 7.1 %, have decreased. Notably, China had the greatest incidence (1.2 million cases), prevalence (573,000 cases), and number of YLDs (55,400 cases), all in 2019. The greatest age-standardized incidence rate (143/100,000) and age-standardized prevalence rate (65/100,000) were both recorded in Greenland in the same year. It's critical to emphasize that men experience these fractures at considerably higher rates than women. Around 70 % of incident instances included unintentional injuries worldwide and across all regions. High-socioeconomic regions had the highest rates of incidence, prevalence, and YLDs, albeit these rates have declined by 6.4 % to 7.1 % since 1990, whereas low-middle and low-income areas have had rises. CONCLUSIONS: This study, which spans the years 1990 to 2019, provides a thorough and current assessment of the global burden attributed to sternum and rib fractures. In terms of nations, regions, sociodemographic index (SDI) levels, age groups, genders, and reasons, it reveals significant variances and trends. The knowledge obtained from this study can be extremely useful in formulating health policy, allocating resources, and developing methods to prevent these injuries.

BACKGROUND: Malignant neoplasm of bone and articular cartilage (MNBAC) is one of the causes of cancer-related deaths worldwide. To date, there is a lack of detailed studies on the disease burden of MNBAC. METHODS: Data on the incidence, mortality, and disability-adjusted life years (DALYs) of MNBAC from 1990 to 2021 were obtained from the Global Burden of Disease study. We estimated the trends in the burden of MNBAC by calculating the estimated annual percentage change (EAPC) in age-standardized rates by region, country, and social development index. RESULTS: Globally, the cases of incidence and deaths of MNBAC showed a significant upward trend. In 2021, the global incidence cases of MNBAC were 91,375.1 (73,780.4-102,469.7), and the number of deaths was 66,114.3 (53,305.4-74,466.9). The age-standardized incidence, mortality, and DALYs rates were all on the rise, with EAPCs of 0.59 (0.51 to 0.68), 0.11 (0.02 to 0.21), and 0.08 (0 to 0.17), respectively. In 2021, China had the highest number of incidence cases and deaths. Two peaks in incidence cases and deaths were observed in the 15-19 and 65-69 age groups, with incidence rates and death rates generally increasing with age, and higher in males than females. The region with the highest incidence cases, deaths, and age-standardized incidence rate was East Asia, while Eastern Sub-Saharan Africa had the highest age-standardized mortality, and DALYs rates. CONCLUSION: From 1990 to 2021, the global burden of MNBAC has continued to increase, particularly in East Asia, which faces the highest number of incidence cases and deaths, while Eastern Sub-Saharan Africa faces the highest ASMR and ASDR. To mitigate this burden, different regions should develop cancer control actions based on their respective epidemiological characteristics, with a focus on the elderly and adolescents, and control of risk factors.

OBJECTIVES: Occupational injuries pose a significant challenge to global health and development. This study aimed to quantify the international and regional burdens of occupational injuries from 1990 to 2019, stratified by specific causes. METHODS: We analysed global trends in deaths, disability-adjusted life years (DALYs), age-standardised mortality rates (ASMR) and age-standardised DALY rates (ASDR) related to occupational injuries. Specific injuries, including animal contact, drowning, mechanical forces, falls, fire, heat, hot substances, foreign bodies, poisoning and road injuries, were evaluated. Age-stratified and regional analyses were also performed. RESULTS: Globally, the number of deaths, DALYs, ASMR and ASDR related to occupational injuries declined from 1990 to 2019. The middle Socio-demographic Index (SDI) region exhibited the highest burden, whereas the high SDI region showed the least burden. China and India had the highest occupational injury-related death rates in 2019. Males, particularly those aged 25-44 years, were found to be more vulnerable. Road injuries were the leading cause of death in all age groups. Compared with 1990, mortality numbers and rates decreased significantly by 2019, with the highest burdens experienced in East Asia, South Asia and Southeast Asia. CONCLUSION: The global decline in occupational injuries is promising; however, certain regions and demographics remain disproportionately affected. Targeted interventions in high-burden areas are crucial to further reduce the impact of occupational injuries.
RESUMO
Few studies have reported the timing and amount of gestational weight gain (GWG) to prevent large-for-gestational-age (LGA) or small-for-gestational-age (SGA). This study aimed to evaluate the association of GWG velocity in each trimester with LGA or SGA based on data from the Taicang and Wuqiang cohort study (TAWS, n = 2008). We used a linear mixed model to evaluate the association of trimester-specific GWG velocity with birthweight categories and stratified by prepregnancy body mass index category and parity. For normal-weight pregnant women, mothers with LGA births had higher GWG velocities than mothers with appropriate-for-gestational-age (AGA) births in the first trimester (0.108 vs. 0.031 kg/week, p < 0.01), second trimester (0.755 vs. 0.631 kg/week, p < 0.01) and third trimester (0.664 vs. 0.594 kg/week, p < 0.01); in contrast, mothers with SGA births had lower GWG velocities than mothers with AGA births in the second trimester (0.528 vs. 0.631 kg/week, p < 0.01) and third trimester (0.541 vs. 0.594 kg/week, p < 0.01). For normal-weight pregnant women with AGA births, multiparous women had lower GWG velocities than primiparous women in the second (0.602 vs. 0.643 kg/week, p < 0.01) and third trimesters (0.553 vs. 0.606 kg/week, p < 0.01). Therefore, for normal-weight women, LGA prevention would begin in early pregnancy and continue until delivery and the second and third trimesters may be critical periods for preventing SGA; in addition, among normal-weight pregnant women with AGA births, multiparous women tend to have lower weight gain velocities than primiparous women.

BACKGROUND: Inappropriate eating behaviors, particularly a lack of food diversity and poor diet quality, have a significant impact on the prognosis of certain chronic conditions and exacerbate these conditions in the community-dwelling elderly population. Current dietary interventions for the elderly have not adequately considered the nutritional needs associated with multiple chronic conditions and personal dietary preferences of elderly individuals. A personalized recommendation system has been recognized as a promising approach to address this gap. However, its effectiveness as a component of an elderly-targeted dietary intervention in real-world settings remains unknown. Additionally, it is unclear whether this intervention approach will be user-friendly for the elderly. Therefore, this study aims to examine the effectiveness of a personalized meal recommendation system designed to improve dietary behavior in community-dwelling elders. The implementation process in terms of System usability and satisfaction will also be assessed. METHODS: The trial has been designed as a 6-month, non-blinded, parallel two-arm trial. One hundred fifty community-dwelling elders who meet the eligibility criteria will be enrolled. Subjects will be allocated to either the intervention group, receiving personalized meal recommendations and access to corresponding food provided as one component of the intervention, as well as health education on elder nutrition topics, or the control group, which will receive nutritional health education lectures. Outcomes will be measured at three time points: baseline at 0 months, 3 months, and 6 months. The primary outcomes will include dietary diversity (DDS) and diet quality (CDGI-E) of enrolled community-dwelling elders, representing their dietary behavior improvement, along with dietary behavior adherence to recommended meals. Secondary outcomes will measure the perceived acceptability and usability of the personalized meal recommendation system for the intervention group. Exploratory outcomes will include changes in the nutritional status and anthropometric measurements of the community-dwelling elders. DISCUSSION: This study aims to examine the effectiveness, acceptability, and usability of a personalized meal recommendation system as a data-driven dietary intervention to benefit community-dwelling elders. The successful implementation will inform the future development and integration of digital health strategies in daily nutrition support for the elderly.

Background: While maternal adherence to a healthy lifestyle was shown to be associated with a lower risk of obesity in offspring, the potential role of overall parental lifestyles has not yet been explored. We aimed to address this gap by exploring whether parental adherence to an overall healthy lifestyle was associated with a lower risk of obesity in offspring. Methods: We included 5881 children and adolescents aged 6-15 years at enrolment in the 2010, 2012, and 2014 waves of the China Family Panel Studies (CFPS) who were free of obesity and followed them until 2020. Parental healthy lifestyle score at study baseline was composed of five modifiable lifestyle factors (0-5; 1 for each): never smoking, non-habitual drinking, weekly exercise, modified dietary diversity score ≥5 points, and body mass index (BMI) of 18.5-23.9 kg/m2. We defined obesity according to the age- and gender-specific cutoffs by the BMI percentile curves for Chinese children aged 6-18 years. We used multivariable Cox proportional hazard models to examine the association between parental healthy lifestyle score (both as continuous and categorical variables) and risk of offspring obesity. Results: Overall, 597 (10.2%) offspring developed obesity during a median follow-up of 6 years. Compared to the lowest tertile of parental healthy lifestyle score, participants in the highest tertile had a 42% (hazard ratio (HR) = 0.58; 95% confidence interval (CI) = 0.45-0.74) lower risk of obesity. Both maternal (HR = 0.75; 95% CI = 0.61-0.92) and paternal (HR = 0.73; 95% CI = 0.60-0.89) healthy lifestyle scores were associated with lower risks of obesity in offspring. For specific lifestyle factors, we observed beneficial associations for paternal diverse diet (HR = 0.73; 95% CI = 0.60-0.88) and healthy BMI (HR = 0.65; 95% CI = 0.55-0.78). Conclusions: Adherence to an overall parental healthier lifestyle was associated with a lower risk of obesity in childhood and adolescence. This finding highlights the potential benefits of promoting a healthy lifestyle among parents for the primary prevention of offspring obesity.

Background: Dietary monitoring is critical to maintaining human health. Social media platforms are widely used for daily recording and communication for individuals' diets and activities. The textual content shared on social media offers valuable resources for dietary monitoring. Objective: This study aims to describe the development of iFood, an applet providing personal dietary monitoring based on social media content, and validate its usability, which will enable efficient personal dietary monitoring. Methods: The process of the development and validation of iFood is divided into four steps: Diet datasets construction, diet record and analysis, diet monitoring applet design, and diet monitoring applet usability assessment. The diet datasets were constructed with the data collected from Weibo, Meishijie, and diet guidelines, which will be used as the basic knowledge for further model training in the phase of diet record and analysis. Then, the friendly user interface was designed to link users with backend functions. Finally, the applet was deployed as a WeChat applet and 10 users from the Beijing Union Medical College have been recruited to validate the usability of iFood. Results: Three dietary datasets, including User Visual-Textual Dataset, Dietary Information Expansion Dataset, and Diet Recipe Dataset have been constructed. The performance of 4 models for recognizing diet and fusing unimodality data was 40.43%(dictionary-based model), 18.45%(rule-based model), 59.95%(Inception-ResNet-v2), and 51.38% (K-nearest neighbor), respectively. Furthermore, we have designed a user-friendly interface for the iFood applet and conducted a usability assessment, which resulted in an above-average usability score. Conclusions: iFood is effective for managing individual dietary behaviors through its seamless integration with social media data. This study suggests that future products could utilize social media data to promote healthy lifestyles.
RESUMO
OBJECTIVE: To explore whether there are differences in the levels of protein, glucose and blood lipids in umbilical vein and umbilical artery blood of newborns with different delivery modes, and to evaluate their value as indicators of fetal intrauterine nutrition and nutritional support. METHODS: A total of 89 pairs of mothers and infants who were delivered in Danyang People's Hospital of Jiangsu Province from June to September 2021 were selected as the study subjects, including 38 cases of spontaneous delivery and 51 cases of cesarean section. The basic information of pregnant women, pregnancy information, newborn delivery and physical examination information were extracted from the medical record information system of the hospital. According to the mode of delivery, HITACHI 7600 automatic biochemical analyzer was used to measure the levels of protein, glucose and blood lipids in umbilical vein and umbilical artery blood, including total protein(TP), albumin(ALB), glucose(GLU), total cholesterol(TC), triglyceride(TG), high density lipoprotein cholesterol(HDL-C), low density lipoprotein cholesterol(LDL-C). The data were statistically analyzed using IBM SPSS Statistics 26.0 statistical software. RESULTS: The levels of TP, ALB, GLU, TC, TG, HDL-C and LDL-C in the umbilical vein blood of the spontaneous delivery group were(56.40±5.83)g/L, (38.41±3.43)g/L, (4.55±1.53)mmol/L, (1.68±0.42)mmol/L, (0.25±0.11)mmol/L, (0.84±0.17)mmol/L and(0.69±0.23)mmol/L, respectively. The levels of TP, ALB, GLU, TC, TG, HDL-C and LDL-C in umbilical artery blood were(56.49±9.91)g/L, (37.72±4.77)g/L, (4.07±1.52)mmol/L, (1.60±0.42)mmol/L, (0.24±0.10)mmol/L, (0.80±0.18)mmol/L and(0.68±0.24)mmol/L, respectively. The levels of TP, ALB, GLU, TC, TG, HDL-C and LDL-C in umbilical vein blood of cesarean section group were(52.08±4.12)g/L, (36.12±2.13)g/L, (3.45±1.16)mmol/L, (1.61±0.39)mmol/L, (0.19±0.08)mmol/L, (0.82±0.18)mmol/L and(0.61±0.20)mmol/L, respectively. The levels of TP, ALB, GLU, TC, TG, HDL-C and LDL-C in umbilical artery blood were(51.49±7.59)g/L, (35.40±3.60)g/L, (3.09±1.15)mmol/L, (1.48±0.40)mmol/L, (0.19±0.08)mmol/L, (0.78±0.18)mmol/L and(0.60±0.20)mmol/L, respectively. The levels of TP, ALB, Glu and TG in cord vein blood and cord artery blood in spontaneous labor group were significantly higher than those in cesarean section group(P<0.05); The levels of Glu, TC, TG and HDL-C in cord vein blood were significantly higher in spontaneous labor group and cesarean section group than those in cord artery blood(P<0.05). CONCLUSION: The levels of protein, glucose and blood lipids in umbilical vein and umbilical artery blood were different among different delivery modes.

This study aims to explore the relationship between macrosomia and amino acids in maternal and cord sera. METHODS: In the case-control study, 78 pairs of mothers and newborns were recruited from December 2016 to November 2019. Participants were divided into the macrosomia group (BW ≥ 4000 g, n = 39) and the control group (BW between 2500 g and 3999 g, n = 39) according to the birth weight (BW) of newborns. Maternal vein blood samples were collected before delivery and cord vein blood samples were collected after birth. The levels of amino acids in maternal and cord sera were measured by liquid chromatography and mass spectrometry (LC-MS/MS) in the year 2021. The difference in amino acid levels in maternal and cord sera between the two groups was compared, and the contribution of each amino acid to the difference between the two groups was analyzed. Unconditional logistic regression analysis was used to test the relationship between macrosomia and amino acids. RESULTS: In maternal serum during the antepartum, the levels of asparagine, glutamine, methionine, alanine, and threonine in the macrosomia group were higher but arginine was lower than that in the control group (p < 0.05). In cord serum, the levels of lysine, histidine, phenylalanine, arginine, tryptophan, valine, isoleucine, glutamate, tyrosine, and total essential amino acid (EAA) in the macrosomia group were lower while glutamine was higher than that in the control group (p < 0.05). The ratios of EAA, valine, threonine, methionine, tryptophan, and alanine in maternal serum to those in cord serum were higher, while the ratio of glutamine was lower in the macrosomia group (p < 0.05). Arginine and threonine in maternal serum and glutamate, glutamine, and histidine in cord serum were associated with macrosomia (p < 0.05). CONCLUSION: Most of the amino acid levels in the maternal sera of the macrosomia group are higher than those in the control group, while most of the amino acids' levels in the cord sera of the macrosomia group are lower than those in the control group. The ratios of some amino acids in maternal serum to those in cord serum were different between the two groups. Arginine and threonine in maternal serum and glutamate, glutamine, and histidine in cord serum are closely related to macrosomia.

OBJECTIVE: To investigate the difference of cortical hormones in cord artery and vein blood of newborns with different delivery modes. METHODS: A total of 65 pregnant women who delivered in the People's Hospital of Danyang City, Jiangsu Province from June to September 2021 were selected as the study subjects, including 26 cases of spontaneous delivery and 39 cases of cesarean section. The basic information of 65 pregnant women and newborns was collected by questionnaire survey. According to the mode of delivery, the levels of corticosteroids in umbilical vein and umbilical artery blood were determined by liquid chromatography-tandem mass spectrometry(LC-MS/MS), including corticosterone, 11-desoxycorticosterone, aldosterone, cortisol, 11-deoxycortisol and cortisone. The data were statistically analyzed using IBM SPSS Statistics 26.0 statistical software. RESULTS: The levels of cortisol, 11-deoxycortisol, aldosterone, cortisol, 11-deoxycortisol and cortisone in the umbilical vein blood of the spontaneous delivery group were(2.44±1.87), (0.64±0.29), (0.49±0.35), (54.95±40.80), (3.20±1.23) and(142.27±57.42)ng/mL, respectively. The levels of corticosterone, 11-deoxycortisol, aldosterone, cortisol, 11-deoxycortisol and cortisone in umbilical artery blood were(4.51±4.47), (0.57±0.28), (0.42±0.29), (60.79±45.53), (2.69±1.25) and(123.10±46.32)ng/mL, respectively. The levels of corticosterone, 11-deoxycortisone, aldosterone, cortisol, 11-deoxycortisone and cortisone in umbilical vein blood of cesarean section group were(0.94±1.09), (0.47±0.14), (0.26±0.14), (22.63±19.82), (2.30±0.90) and(84.51±29.49)ng/mL, respectively. The levels of corticosterone, 11-deoxycortisol, aldosterone, cortisol, 11-deoxycortisol and cortisone in umbilical artery blood were(2.22±2.24), (0.43±0.17), (0.27±0.14), (30.09±25.93), (1.87±0.76) and(75.03±24.90)ng/mL, respectively. The levels of corticosterone, 11-desoxycorticosterone, aldosterone, cortisol, 11-deoxycortisol and cortisone in cord vein blood and cord artery blood in spontaneous labor group were significantly higher than those in cesarean section group(P<0.05). The levels of corticosterone and cortisol in cord vein blood were significantly lower in spontaneous labor group and cesarean section group than those in cord artery blood(P<0.05), the levels of 11-desoxycorticosterone, 11-deoxycortisol and cortisone in cord vein blood were significantly higher in spontaneous labor group and cesarean section group than those in cord artery blood(P<0.05). CONCLUSION: There are differences in the level of cortical hormones in cord artery and vein blood in different delivery modes.

OBJECTIVE: To examine the association of pre-pregnancy body mass index(BMI) and first-trimester glucose and lipid metabolism. METHODS: A total of 298 pregnant women with high risk factors for gestational diabetes in early pregnancy, with an average age of 32.24 years, 66.11% were primiparous and the average time for blood collection was 12.5 weeks, were collected from August 2021 to April 2022 at the Department of Nutrition, Haidian District Maternal and Child Health Hospital, Beijing. Pregnant women were divided into low weight group(n=15), normal weight group(n=181), overweight/obese group(n=102) according to their pre-pregnancy BMI. Fasting glucose, fasting insulin, lipid quadruple, C-reactive protein, leptin and adiponectin levels were compared among groups. RESULTS: (1)Triglyceride concentrations were significantly higher in women in the overweight/obese group(1.51 mmol/L vs.1.15 mmol/L) than in women in low weight group(P<0.01). HDL cholesterol(HDL-C) levels were lower than in women with low weight(1.64 mmol/L vs.1.95 mmol/L)(P<0.01). (2)Pre-pregnancy low weight women had reduced pancreatic ß-cell function in early pregnancy with the HOMA-ß index of 60.41%, and women in the overweight/obese group had heavier fasting insulin levels(7.86 vs.3.42 µU/mL) and insulin resistance(1.75 vs 0.74) in early pregnancy than low weight women(P<0.01). (3)Pre-pregnancy BMI was positively correlated with triglycerides, fasting insulin, C-reactive protein levels, and degree of insulin resistance in early pregnancy(r=0.30, 0.28, 0.45 and 0.45, P<0.01)and negatively correlated with HDL-C levels in early pregnancy(r=-0.29, P<0.01). CONCLUSION: Among pregnant women with risk factors for gestational diabetes, pre-pregnancy overweight and obesity are associated with glucose and lipid metabolism levels in early pregnancy.

BACKGROUND: Human milk oligosaccharides (HMOs) are the third most abundant component of human milk. Various factors may affect the concentration of HMOs, such as the lactation period, Lewis blood type, and the maternal secretor gene status. OBJECTIVES: The purpose of this study is to investigate factors associated with HMO concentrations in Chinese populations. METHODS: A sub-sample of 481 was randomly selected from a large cross-sectional study in China (n = 6481) conducted in eight provinces (Beijing, Heilongjiang, Shanghai, Yunnan, Gansu, Guangdong, Zhejiang, and Shandong) between 2011 and 2013. HMO concentrations were determined by a high-throughput UPLC-MRM method. Various factors were collected through face-to-face interviews. Anthropometric measurement was conducted by trained staff. RESULTS: Median total HMO concentration was 13.6 g/L, 10.7 g/L, and 6.0 g/L for colostrum, transitional milk, and mature milk, respectively. HMO concentration decreased significantly as the lactation period increased (p < 0.0001). There were significant differences of average total HMO concentration between secretor mothers and non-secretor mothers (secretor 11.3 g/L vs. non-secretor 5.8 g/L, p < 0.0001). There were significant differences of average total HMO concentrations among three Lewis blood types (p = 0.003). Comparing with the concentration of total oligosaccharides of Le+ (a-b+), average of total oligosaccharides concentrations increased by 3.9 (Le+ (a+b-), p = 0.004) and 1.1 g/L (Le- (a-b-), p = 0.049). The volume of breast milk expressed and the province the mother came from affected the concentration of total oligosaccharides (all p < 0.0001). Maternal BMI (p = 0.151), age (p = 0.630), prematurity (p = 0.850), mode of delivery (p = 0.486), infants' gender (p = 0.685), maternal education level (p = 0.989), maternal occupation (p = 0.568), maternal allergic history (p = 0.370), maternal anemia (p = 0.625), pregnancy-induced hypertension (p = 0.739), gestational diabetes (p = 0.514), and parity (p = 0.098) were not significantly correlated with the concentration of milk oligosaccharides. The concentrations of 2'-fucosyllactose (2'-FL), lacto-N-neotetraose (LNnT), sialyllacto-N-tetraose c (LSTc), lacto-N-fucopentaose I (LNFP-I), disialylated lacto-N-tetraose (DSLNT), difucosyl-para-lacto-N-neohexaose (DFpLNnH), difucosyl-lacto-N-hexaose (DFLNH[a]), and 3-sialyllactose (3'-SL) showed a gradual downward trend, while the concentration of 3-fucosyllactose (3-FL) showed a gradual upward trend among three lactation stages (p < 0.05). CONCLUSIONS: The concentration of HMOs changes throughout lactation, and it varies between different HMOs. HMO concentrations differed between lactation stage, maternal secretor gene status, Lewis blood type, volume of breast milk expressed, and the province the mother came from. Prematurity, mode of delivery, parity, infants' gender, and maternal characteristics did not affect the HMO concentration. Geographical region may be not associated with HMOs concentration in human milk. There may be a mechanism for co-regulation of the secretion of some of the oligosaccharides such as 2'FL vs. 3FL, 2'FL vs. LNnT, and lacto-N-tetraose (LNT).

BACKGROUND: Maternal adherence to a healthy lifestyle has been associated with a lower risk of obesity in offspring. However, little is known about the potential effect of an overall healthy parental lifestyle on the development of obesity in children. We aimed to investigate the prospective association of parental adherence to a combination of healthy lifestyle factors with the risk of obesity in offspring. METHODS: Participants in the China Family Panel Studies, without obesity at baseline, were enrolled between April and September, 2010; between July, 2012, and March, 2013; and between July, 2014, and June, 2015; and followed up until the end of 2020. Parental healthy lifestyle score (ranged 0-5) was characterised by five modifiable lifestyle factors: smoking, alcohol consumption, exercise, diet, and BMI. The first occurrence of offspring obesity during the study follow-up period was defined by age-specific and sex-specific cutoff values of BMI. We used multivariable-adjusted Cox proportional hazard models to examine the associations between parental healthy lifestyle scores and risk of obesity in children. FINDINGS: We included 5881 participants aged 6-15 years; median follow-up was 6 years (IQR 4-8). A total of 597 (10·2%) participants developed obesity during follow-up. Compared with those in the lowest tertile of parental healthy lifestyle scores, participants in the top tertile had a 42% lower risk of obesity (multivariable-adjusted hazard ratio [HR] 0·58 [95% CI 0·45-0·74]). The association persisted in sensitivity analyses and was similar across major subgroups. Both maternal (HR 0·75 [95% CI 0·61-0·92]) and paternal (0·73 [0·60-0·89]) healthy lifestyle scores were independently associated with lower risks of obesity in offspring, with significant contributions observed for paternal diverse diet and healthy BMI. INTERPRETATION: Adherence to an overall parental healthier lifestyle was associated with a substantially lower risk of obesity in childhood and adolescence. This finding highlights the potential benefits of promoting a healthy lifestyle among parents for the primary prevention of obesity in offspring.

Objective: This study systematized information about vitamin E concentration in healthy breast milk during different stages of lactation in order to support the strategies of protecting postpartum women and infants. Methods: Studies published before April 30th, 2021, which detected vitamin E concentration in breast milk of healthy women by High Performance Liquid Chromatography (HPLC) or Ultra High Performance Liquid Chromatographic (UHPLC), were evaluated. The databases of CNKI (Chinese), WanFang Data (Chinese), VIP (Chinese), PubMed, Cochrane Library, Web of Science and Embase were searched. The random effect models were used to conduct meta-analysis by the statistical software package Stata 14.0. Results: In all 4,791 searched publications, 53 with full text were selected, which included 46 descriptive studies, 1 case-control study, 1 non-randomized controlled trial, and 5 randomized controlled trials. The pooled mean of vitamin E concentration was 10.57 mg α-TE/L (95%CI 8.94-12.20) in colostrum, 4.03 mg α-TE/L (95%CI 3.29-4.77) in transitional milk and 3.29 mg α-TE/L (95%CI 2.95-3.64) in mature milk. Subgroup analysis showed that vitamin E concentration of colostrum in Asian countries was lower than that in Western countries in colostrum and transitional milk. Conclusions: Vitamin E concentration in breast milk decreased during lactation until the mature milk was produced. The vitamin E concentration of colostrum in Asian countries was evidently lower than that in Western countries. The vitamin E concentration in mature milk is similar in different regions. The concentration of vitamin E in breast milk started to be stable from about 2 to 3 weeks postpartum until 4 or 6 months postpartum, but it needs additional evidence to support.
RESUMO
Humans require vitamin A (VA). However, pooled VA data in human milk is uncommon internationally and offers little support for dietary reference intake (DRIs) revision of infants under 6 months. As a result, we conducted a literature review and a meta-analysis to study VA concentration in breast milk throughout lactation across seven databases by August 2021. Observational or intervention studies involving nursing mothers between the ages of 18 and 45, with no recognized health concerns and who had full-term infants under 48 months were included. Studies in which retinol concentration was expressed as a mass concentration on a volume basis and determined using high-, ultra-, or ultra-fast performance liquid chromatography (HPLC, UPLC, or UFLC) were chosen. Finally, 76 papers involving 9171 samples published between 1985 and 2021 qualified for quantitative synthesis. Results from the random-effects model showed that the VA concentration of healthy term human milk decreased significantly as lactation progressed. VA (µg/L) with 95% CI at the colostrum, transitional, early mature and late mature stages being 920.7 (744.5, 1095.8), 523.7 (313.7, 733.6), 402.4 (342.5, 462.3) and 254.7 (223.7, 285.7), respectively (X2 = 71.36, p < 0.01). Subgroup analysis revealed no significant differences identified in VA concentration (µg/L) between Chinese and non-Chinese samples at each stage, being 1039.1 vs. 895.8 (p = 0.64), 505.7 vs. 542.2(p = 0.88), 408.4 vs. 401.2 (p = 0.92), 240.0 vs. 259.3 (p = 0.41). The findings have significant implications for the revision of DRIs for infants under six months.

Importance: In 2009, the US National Academy of Medicine (NAM) released revised gestational weight gain (GWG) guidelines, which were established primarily for White North American women and may be unsuitable for Asian women. In 2021, the Chinese Nutrition Society (CNS) released its GWG guidelines, but their applicability requires re-examination. Objective: To compare the differences between the CNS and NAM recommendations for GWG in association with health outcomes in the offspring of Chinese women. Design, Setting, and Participants: In this bidirectional cohort study, children in China were recruited at age 3 years from 2017 to 2018, with 2 follow-up visits over the next 2 years (between September 2017 and September 2020). Information during pregnancy was retrieved from medical records. Data analysis was performed from October 2021 to January 2022. Main Outcomes and Measures: GWG was classified as insufficient, appropriate, or excessive according to the CNS and NAM guidelines separately. Children's height, weight, fat mass, fat-free mass, and percentage of body fat were measured at each visit. Body mass index, fat mass index, fat-free mass index, weighted κ score, risk ratio values, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated. Results: A total of 3822 children (1996 boys and 1826 girls; mean [SD] age, 3.79 [0.30] years) were enrolled; after exclusions, 3170 term singleton children were recruited and were followed at 4 and 5 years of age. According to the CNS guidelines, the prevalence rates were 14.1% for insufficient GWG, 48.1% for appropriate GWG, and 37.9% for excessive GWG, whereas the rates according to NAM guidelines were 39.7% for insufficient GWG, 37.2% for appropriate GWG, and 23.1% for excessive GWG. The weighted κ value for the classification agreement between the 2 guidelines was 0.530 (95% CI, 0.510-0.550). For the appropriate GWG group, the rates for low nutritional levels did not differ between the 2 guidelines, but the rates for high nutritional levels were significantly lower under CNS guidelines than under NAM guidelines. When the sensitivity, specificity, PPV, and NPV with respect to the mothers who maintained appropriate GWG were used to estimate the nonhigh nutritional status of their offspring, generally higher values based on the CNS guidelines were found compared with those based on the NAM recommendations. Conclusions and Relevance: These findings suggest that the GWG recommendations promulgated by the NAM are higher than the CNS guidelines, with the latter more suitable for Chinese women.

Background: Lactopontin (LPN) in breast milk, also known as milk osteopontin is thought to play a myriad of important roles in infants when they are immature. The purpose of the present study was to examine the longitudinal changes in LPN concentrations in term and preterm milk, and elucidate the links between maternal characteristics, LPN levels, and child growth in a birth cohort. Methods: 131 mothers who delivered term, moderate-late preterm (MPT), very preterm (VPT), and extremely preterm (EPT) infants were included, milk samples were collected at 7, 14, 28, and 120 days postpartum. LPN concentration was determined by multiple reaction monitoring (MRM) using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Results: Our results indicated that LPN change over time of VPT (P = 0.024) and EPT (P = 0.003) were significantly different from term milk, although they all gradually decreased with lactation. In terms of LPN-related factors, maternal age was a significant contributor in late mature milk and pre-pregnancy BMI a significant contributor to colostrum and transitional milk. We further investigated relationships between LPN levels and infant weight and our results suggested that high levels of LPN in breast milk might be useful for the catch-up growth of infants. Conclusion: LPN levels in breast milk are related to maternal factors, and differences in LPN levels may affect the growth of infants. As milk is a critical part in the mother-breastmilk-infant "triad," the association between maternal-infant factors and milk LPN levels warrants further study.
RESUMO
Human milk oligosaccharides (HMOs) have attracted increasing attention due to the emerging evidence of their positive roles for infant's health. A high-throughput method for absolute quantitation of the complex HMOs including multiple isomeric structures is important but very challenging, due to the highly divers nature and wide variation in content of HMOs from different individuals. Here we used UPLC-MS-MRM in the negative-ion mode for accurate quantitation of 23 complex HMOs in just 15 min. The selected oligosaccharides are in their native forms and include neutral and sialylated, fucosylated and non-fucosylated, linear and branched, and secretor and Lewis phenotype indicators. The well validated method with good sensitivity, recovery and reproducibility was then applied to a large population quantitative survey of 251 Chinese mothers from five different ethnic groups (Han, Zhuang, Hui, Mongolian and Tibetan) living in different geographical regions for their secretor's status and Lewis phenotypes.
