RESUMEN
BACKGROUND: Alzheimer's disease (AD), the most common type of irreversible dementia, is predicted to affect 152 million people by 2050. Evidence from large-scale preventive randomized controlled trials (RCTs) on modifiable risk variables in Europe has shown that multi-domain lifestyle treatments for older persons at high risk of dementia may be practical and effective. Given the substantial differences between the Chinese and European populations in terms of demographics and living conditions, direct adoption of the European program in China remains unfeasible. Although a RCT has been conducted in China previously, its participants were mainly from rural areas in northern China and, thus, are not representative of the entire nation.There is an urgent need to establish cohorts that represent different economic, cultural, and geographical situations in order to explore implementation strategies and evaluate the effects of early multi-domain interventions more comprehensively and accurately. MEDTODS: We developed an integrated intervention procedure implemented in urban neighborhood settings, namely China Initiative for Multi-Domain Intervention (CHINA-IN-MUDI). CHINA-IN-MUDI is a 2-year multicenter open-label cluster-randomised controlled trial centered around a Chinese-style multi-domain intervention to prevent cognitive decline. Participants aged 60-80 years were recruited from a nationally representative study, i.e. China Healthy Aging and Dementia Study cohort. An external harmonization process was carried out to preserve the original FINGER design. Subsequently, we standardized a series of Chinese-style intervention programs to align with cultural and socioeconomic status. Additionally, we expanded the secondary outcome list to include genomic and proteomic analyses. To enhance adherence and facilitate implementation, we leveraged an e-health application. RESULTS: Screening commenced in July 2022. Currently, 1,965 participants have been randomized into lifestyle intervention (n = 772) and control groups (n = 1,193). Both the intervention and control groups exhibited similar baseline characteristics. Several lifestyle and vascular risk factors were present, indicating a potential window of opportunity for intervention. The intervention will be completed by 2025. CONCLUSIONS: This project will contribute to the evaluation of the effectiveness and safety of intervention strategies in controlling AD risk and reducing clinical events, providing a basis for public health decision-making in China.

Objective: To explore potential predictors of refractory Mycoplasma pneumoniae pneumonia (RMPP) in early stage. Methods: The prospective multicenter study was conducted in Zhejiang, China from May 1st, 2019 to January 31st, 2020. A total of 1 428 patients with fever >48 hours to <120 hours were studied. Their clinical data and oral pharyngeal swab samples were collected; Mycoplasma pneumoniae DNA in pharyngeal swab specimens was detected. Patients with positive Mycoplasma pneumoniae DNA results underwent a series of tests, including chest X-ray, complete blood count, C-reactive protein, lactate dehydrogenase (LDH), and procalcitonin. According to the occurrence of RMPP, the patients were divided into two groups, RMPP group and general Mycoplasma pneumoniae pneumonia (GMPP) group. Measurement data between the 2 groups were compared using Mann-Whitney U test. Logistic regression analyses were used to examine the associations between clinical data and RMPP. Receiver operating characteristic (ROC) curves were used to analyse the power of the markers for predicting RMPP. Results: A total of 1 428 patients finished the study, with 801 boys and 627 girls, aged 4.3 (2.7, 6.3) years. Mycoplasma pneumoniae DNA was positive in 534 cases (37.4%), of whom 446 cases (83.5%) were diagnosed with Mycoplasma pneumoniae pneumonia, including 251 boys and 195 girls, aged 5.2 (3.3, 6.9) years. Macrolides-resistant variation was positive in 410 cases (91.9%). Fifty-five cases were with RMPP, 391 cases with GMPP. The peak body temperature before the first visit and LDH levels in RMPP patients were higher than that in GMPP patients (39.6 (39.1, 40.0) vs. 39.2 (38.9, 39.7) â, 333 (279, 392) vs. 311 (259, 359) U/L, both P<0.05). Logistic regression showed the prediction probability π=exp (-29.7+0.667×Peak body temperature (â)+0.004×LDH (U/L))/(1+exp (-29.7+0.667×Peak body temperature (â)+0.004 × LDH (U/L))), the cut-off value to predict RMPP was 0.12, with a consensus of probability forecast of 0.89, sensitivity of 0.89, and specificity of 0.67; and the area under ROC curve was 0.682 (95%CI 0.593-0.771, P<0.01). Conclusion: In MPP patients with fever over 48 to <120 hours, a prediction probability π of RMPP can be calculated based on the peak body temperature and LDH level before the first visit, which can facilitate early identification of RMPP.

OBJECTIVE: To investigate the impact of dietary and underlying factors on the iron status of women in early pregnancy and to provide evidence for preventing iron deficiency and iron deficiency anemia, thereby reducing the incidence of associated adverse outcomes. METHODS: From November to December 2018, women in the first trimester of pregnancy (< 12 weeks gestation) who established prenatal records at the Shunyi District Maternal and Child Health Hospital, Beijing, were enrolled in this study, in which 388 participants were accessed for data including demographic characteristics, anthropometric measurements, parity, biomarkers reflecting iron status, and food-frequency questionnaire. SPSS 26.0 were used for statistical analysis. Dietary patterns were extracted using principal component analysis, and factor scores of each dietary pattern were calculated. Two-sided Fisher exact probability test and one-way ANOVA were conducted to access differences in iron status among the groups, and the differences were significant if P < 0.05. Iron deficiency was defined as serum ferritin(SF) < 30 µg/L. To analyze the potential role of dietary factors on iron deficiency during the first trimester, the collected data listed above were adopted as independent factors for the cross-sectional Logistic regression. We used Logistic regression to analyze the potential effects of baseline characteristics and dietary factors on iron status. RESULTS: Among the 388 participants included in the analysis, 121 (32.2%) were iron deficient, in which 107 (27.6%) were iron depletion (ID), 8 (2.1%) were iron deficiency erythropoiesis (IDA), 6(1.5%) were iron deficiency anemia. The mean SF concentration was (50.4±35.3) µg/L. Multiparity(OR=3.9, 95%CI: 1.81-8.42, P=0.001)was a risk factor for iron deficiency during early pregnancy. No significant iron status differences were found among the participants with different educational levels and anthropometric measurements. In contrast, age (OR =0.96, 95%CI: 0.94-0.97, P < 0.001) was a protective factor. For multiparas, taking iron-containing supplements might have a protective effect for iron deficiency (OR=0.27, 95%CI: 0.09-0.83, P=0.022). The balance-diet pattern (OR=0.81, 95%CI: 0.66-1.00, P=0.054) only showed a marginally significant effect. CONCLUSION: Increasing attention should be paid to the iron status of pregnant multiparas and young pregnant women. For those women of reproductive age with the risk factors listed above, especially for multiparas, iron-containing supplements should be recommended to prevent gestational iron deficiency. The effect of the "balance" dietary pattern on iron status in the first trimester and following requires further research and discussion.

Objective: Based on a cohort and intervention study of the Eastern Chinese Student Surveillance, Cohort and Intervention Study (ES-SCI), this research aims to explore the correlation between monitor of the school environment and longitudinal data on myopia and provide evidence for the government myopia intervention strategy. Methods: This survey adopts the stratified cluster sampling method with the school as the unit. Students from grade 1 to grade 3 were selected according to the whole class to monitor the school environment in the classroom. Students will use the full-automatic computer optometer (TOPCON RM800) to conduct optometry from 2019 to 2021 under the condition of mydriasis to perform refractive eye examinations. Meantime eye axis length monitoring was also conducted. Cox proportional risk regression model was used to explore the relationship between school environmental monitoring and the occurrence and development of students' myopia. Results: From 2019 to 2021, 2 670 students from 77 classrooms participated in the observation study. The students' diopter after right/left eye mydriasis decreased in varying degrees (P<0.001), and the axial length of the right/left eye increased in various degrees (P<0.001). The weighted qualified rate of per capita area of primary school classrooms increased from 18.0% in 2019 to 26.0% in 2021, the weighted average illuminance pass rate of blackboard surface increased from 23.8% in 2019 to 26.4% in 2021, and the weighted average illuminance pass rate of classroom table decreased from 86.7% in 2019 to 77.5% in 2021. The trend chi-square test was significant (P<0.05). Cox proportional risk regression showed that after correcting for the grade, gender, parental myopia, diet, sleep, near work (sitting posture, working time, electronic mobile equipment, eye exercises), and outdoor activities, the per capita area of 1.36- m2 was the protective factor of eye axis length (HR=0.778, 95%CI: 0.659-0.918, P=0.003); The average reflection ratio of blackboard 0.15-0.19 was the protective factor of eye axis length (HR=0.685, 95%CI: 0.592-0.793, P<0.001); The average illumination of the blackboard 150-, 300-, 500- lx was the protective factor of the eye axis length (HR=0.456, 95%CI: 0.534-0.761, P<0.001; HR=0.794, 95%CI: 0.705-0.895, P<0.001; HR=0.690, 95%CI: 0.619-0.768, P<0.001). The blackboard evenness 0.40-0.59 was the risk factor of eye axis length (HR=1.528, 95%CI: 1.018-2.293, P=0.041), and the blackboard evenness 0.80- was the protection factor of eye axis length (HR=0.542, 95%CI: 0.404-0.726, P<0.001). The evenness of the desktop 0.40-0.59 was the protective factor of eye axis length (HR=0.820, 95%CI: 0.698-0.965, P=0.017). The average illuminance of 150-, 300-, 500- lx was the protective factor of a diopter (HR=0.638, 95%CI: 0.534-0.761, P<0.001; HR=0.911, 95%CI: 0.848-0.978, P=0.011; HR=0.750, 95%CI: 0.702-0.801, P<0.001). The average illumination of desktop 500- lx was a protective factor of a diopter (HR=0.855, 95%CI: 0.763-0.958, P=0.007). Conclusion: School environmental monitoring indicators, such as meeting per capita area standards, passing blackboard, and desk top-related indicators, all play protective effects on myopia development in students.

Objective: To compare oxytocin combined with ergometrine with oxytocin alone in terms of primary prophylaxis for postpartum hemorrhage (PPH) at the time of cesarean section (CS). Methods: This was a multicenter double-blind randomized controlled interventional study comparing ergometrine combined with oxytocin and oxytocin alone administered at CS. From December 2018 to November 2019, a total of 298 parturients were enrolled in 16 hospitals nationwide. They were randomly divided into experimental group (ergometrine intra-myometrial injection following oxytocin intravenously; 148 cases) and control group (oxytocin intra-myometrial injection following oxytocin intravenously; 150 cases) according to 1â¶1 random allocation. The following indexes were compared between the two groups: (1) main index: blood loss 2 hours (h) after delivery; (2) secondary indicators: postpartum blood loss at 6 h and 24 h, placental retention time, incidence of PPH, the proportion of additional use of uterine contraction drugs, hemostatic drugs or other hemostatic measures at 2 h and 24 h after delivery, the proportion requiring blood transfusion, and the proportion of prolonged hospital stay due to poor uterine involution; (3) safety indicators: nausea, vomiting, dizziness and other adverse reactions, and blood pressure at each time point of administration. Results: (1) The blood loss at 2 h after delivery in the experimental group [(402±18) ml] was less than that in the control group [(505±18) ml], and the difference was statistically significant (P<0.05). (2) The blood loss at 6 h and 24 h after delivery in the experimental group were less than those in the control group, and the differences were statistically significant (all P<0.05). There were no significant differences between the two groups in the incidence of PPH, the proportion of additional use of uterine contraction drugs, hemostatic drugs or other hemostatic measures at 2 h and 24 h after delivery, the proportion requiring blood transfusion, and the proportion of prolonged hospital stay due to poor uterine involution (all P>0.05). (3) Adverse reactions occurred in 2 cases (1.4%, 2/148) in the experimental group and 1 case (0.7%, 1/150) in the control group. There was no significant difference between the two groups (P>0.05). The systolic blood pressure within 2.0 h and diastolic blood pressure within 1.5 h of drug administration in the experimental group were higher than those in the control group, and the differences were statistically significant (P<0.05), but the blood pressure of the two groups were in the normal range. Conclusion: The use of ergometrine injection in CS could reduce the amount of PPH, which is safe and feasible.

Objective: To evaluate the nutritional status by the Controlling Nutritional Status (CONUT) score and its association with the long-term prognosis in patients with acute heart failure (AHF). Methods: This prospective monocentric study consecutively enrolled patients admitted to our hospital for AHF from April 2012 to May 2016. Patients were divided into 3 groups based on the CONUT score at admission: normal (0-1), mild malnutrition (2-4) and moderate-severe malnutrition (5-12) groups. Baseline information was obtained and recorded within 24 hours after admission. All patients were followed up every 3 months by outpatient visit or telephone call until March 2019. The primary endpoint was all-cause mortality. The Kaplan-Meier survival curves and log-rank test were used to compare all-cause mortality between groups. Variables showing statistical significance in the univariate analysis were incorporated into multivariate Cox regression model to analyze the independent risk factors for all-cause mortality after discharge. Results: A total of 396 patients were enrolled in this study, including 114 patients with normal nutritional status, 200 patients with mild malnutrition and 82 patients with moderate-severe malnutrition. One hundred and fifty-eight patients died during a median follow-up of 34 (18, 46) months. The mortality was 32.4% (37/114), 39% (78/200) and 52.4% (43/82) in normal, mild malnutrition and moderate-severe malnutrition groups, respectively. The mortality was significantly higher in the moderate-severe malnutrition group than in normal nutrition group (P<0.05). However, there was no significant difference in mortality between normal and mild malnutrition group as well as between mild and moderate-severe malnutrition group (both P>0.05). Kaplan-Meier curves indicated that patients with high CONUT score group was at higher risk of all-cause mortality compared with those with low CONUT score (P=0.002). Cox proportional hazard analyses showed that the risk of all-cause mortality of moderate-severe malnutrition group was significantly higher than that of normal nutrition group (HR =1.648, 95%CI 1.021-2.660, P=0.041). Conclusions: The CONUT score of patients with AHF at admission is associated with the long-term prognosis. High CONUT score is an independent risk factor for all-cause mortality in AHF patients after discharge.

Nighteen people at a restaurant experienced dizziness headaches and other discomforts in six days. According to the description method, the time and location distribution were found to be concentrated. A second Investigation was conducted at the same time as the onset of the case, the test found that the carbon monoxide concentration of second floor up to 539 mg/m(3). The on-site testing found that when 2 steam generator in snack room on the first floor turned on, the carbon monoxide concentration on the top of elevator on the second floor was 1225.0 mg/m(3). After the accident, the restaurant replaced a steam generator, the carbon monoxide concentration on the top of the new and old steam generator were 350 mg/m(3) and >1 000 mg/m(3), respectively. After the steam generators were fitted with exhaust smoke pipe and exhasust hood, the carbon monoxide concentrations of on the top of the vegetable transfer elevator and the room on the second floor were both 0.4 mg/m(3), and there were no cases of recurrence. It was determined that this was a carbon monoxide poisoning incident caused by a high concentration of carbon monoxide emitted by the steam generators, which spread to the second floor of the private room through the vegetable transfer elevator.

Objective: To investigate the etiology of necrotizing pneumonia (NP) in children and the clinical characteristics of NP caused by different pathogens in China. Methods: A retrospective, case-control study was performed in children with NP who were admitted to 13 hospitals in China from January 2008 to December 2019. The demographic and clinical information, laboratory data, etiological and radiological findings were analyzed. The data were divided into three groups based on the following years: 2008-2011, 2012-2015 and 2016-2019, and the distribution characteristics of the pathogens in different period were compared. Meanwhile, the pathogens of pediatric NP in the southern and northern China were compared. And the clinical characteristics of the Mycoplasma pneumoniae (MP) NP and the bacterial NP were also compared. T-test or Mann-Whitney nonparametric test was used for comparison of numerical variables, and χ2 test was used for categorical variables. Results: A total of 494 children with NP were enrolled, the median ages were 4.7 (0.1-15.3) years, including 272 boys and 222 girls. Among these patients, pathogens were identified in 347 cases and the pathogen was unclear in the remaining 147 cases. The main pathogens were MP (238 cases), Streptococcus pneumoniae (SP) (61 cases), Staphylococcus aureus (SA) (51 cases), Pseudomonas aeruginosa (13 cases), Haemophilus influenzae (10 cases), adenovirus (10 cases), and influenza virus A (7 cases), respectively. MP was the most common pathogen in all three periods and the proportion increased yearly. The proportion of MP in 2016-2019 was significantly higher than that in 2012-2015 (52.1% (197/378) vs. 36.8% (32/87), χ2=6.654, P=0.010), while there was no significant difference in the proportion of MP in 2012-2015 and that in 2008-2011 (36.8% (32/87) vs. 31.0% (9/29), χ²=0.314, P=0.575).Regarding the regional distribution, 342 cases were in the southern China and 152 in the northern China. Also, MP was the most common pathogen in both regions, but the proportion of MP was higher and the proportion of SP was lower in the north than those in the south (60.5% (92/152) vs. 42.7% (146/342), χ2=13.409, P<0.010; 7.9% (12/152) vs. 14.3% (49/342), χ2=4.023, P=0.045). Comparing the clinical characteristics of different pathogens, we found that fever and cough were the common symptoms in both single MP and single bacterial groups, but chest pain was more common (17.0% (34/200) vs. 6.1% (6/98), χ2=6.697, P=0.010) while shortness of breath and wheezing were less common in MP group (16.0% (32/200) vs. 60.2% (59/98), χ2=60.688, P<0.01; 4.5% (9/200) vs. 21.4% (21/98), χ2=20.819, P<0.01, respectively). The white blood cell count, C-reactive protein and procalcitonin in the bacterial group were significantly higher than those in the MP group (14.7 (1.0-67.1)×109/L vs. 10.5 (2.5-32.2)×109/L, 122.5 (0.5-277.3) mg/L vs. 51.4 (0.5-200.0) g/L, 2.13 (0.05-100.00) µg/L vs. 0.24 (0.01-18.85) µg/L, Z=-3.719, -5.901 and -7.765, all P<0.01). Conclusions: The prevalence of pediatric NP in China shows an increasing trend during the past years. MP, SP and SA are the main pathogens of NP, and the most common clinical symptoms are fever and cough. The WBC count, C-reactive protein and procalcitonin in bacterial NP are significantly higher than those caused by MP.

Objective: By summarizing the technical points and therapeutic outcomes of combing infratemporal fossa approach (IFA) and internal carotid artery (ICA) reconstruction for the colossal skull base tumor invading ICA in petrous bone, the clinical application value was discussed. Methods: Five patients (2 males, 3 females,aging from 27 to 55 years old) who received surgeries between July 2015 and May 2017 for lateral skull base pathology involved petrous ICA using technique combined IFA and pre-reconstruction, were reviewed. Results: Among the five patients, three were paraganglioma of head and neck, one was carotid aneurysms, and one was recurrent adenoid cystic carcinoma (ACC). The median tumor size in the largest cross-section was 60 mm × 51 mm (range, 28 mm × 22 mm-72 mm × 58 mm). Complete excision was achieved with IFA and ICA reconstruction. The median blood loss volume was 1 000 ml (range, 600-2 500 ml). Four cases showed no new long-term neurologic sequelae, while one showed hemiplegia due to graft vessel occlusion. Except for the one with ACC having facial nerve cut, others achieved good facial nerve function of HB grade â to â ¡ during 3 to 12 months, follow-up. No tumor recurrence was observed over the median duration of follow-up for above 36 months (range, 36-58 months). Conclusion: For lesions involved superior part of ICA, which is unable to separate from ICA, IFA and ICA reconstruction can achieve complete excision.

Objective: To establish a disease risk prediction model for the newborn screening system of inherited metabolic diseases by artificial intelligence technology. Methods: This was a retrospectively study. Newborn screening data (n=5 907 547) from February 2010 to May 2019 from 31 hospitals in China and verified data (n=3 028) from 34 hospitals of the same period were collected to establish the artificial intelligence model for the prediction of inherited metabolic diseases in neonates. The validity of the artificial intelligence disease risk prediction model was verified by 360 814 newborns' screening data from January 2018 to September 2018 through a single-blind experiment. The effectiveness of the artificial intelligence disease risk prediction model was verified by comparing the detection rate of clinically confirmed cases, the positive rate of initial screening and the positive predictive value between the clinicians and the artificial intelligence prediction model of inherited metabolic diseases. Results: A total of 3 665 697 newborns' screening data were collected including 3 019 cases' positive data to establish the 16 artificial intelligence models for 32 inherited metabolic diseases. The single-blind experiment (n=360 814) showed that 45 clinically diagnosed infants were detected by both artificial intelligence model and clinicians. A total of 2 684 cases were positive in tandem mass spectrometry screening and 1 694 cases were with high risk in artificial intelligence prediction model of inherited metabolic diseases, with the positive rates of tandem 0.74% (2 684/360 814)and 0.46% (1 694/360 814), respectively. Compared to clinicians, the positive rate of newborns was reduced by 36.89% (990/2 684) after the application of the artificial intelligence model, and the positive predictive values of clinicians and artificial intelligence prediction model of inherited metabolic diseases were 1.68% (45/2 684) and 2.66% (45/1 694) respectively. Conclusion: An accurate, fast, and the lower false positive rate auxiliary diagnosis system for neonatal inherited metabolic diseases by artificial intelligence technology has been established, which may have an important clinical value.

BACKGROUND: Increased left atrium diameter (LAD) is associated with an elevated risk of cardiovascular diseases. The relationship between nutrition status and left atrial enlargement (LAE) is still unclear. The present study aimed to investigate the association of famine exposure in early life with LAE in adulthood. METHODS: Participants were divided into non-exposed, fetal, early, middle and late childhood exposed groups according to birth data. LAE was defined when LAD was ≥3.9 cm in women and ≥4.1 cm in men, or ≥2.3 cm m-2 by a sex-independent cut-off normalised for body surface area. Multivariate logistic regression was performed to calculate the odds ratio (OR) and confidence interval (CI) between famine exposure and LAE. RESULTS: In total, 2522 [905 male, mean (SD) age 59.1 (3.65) years] subjects were enrolled, including 392 (15.5%) LAE subjects. The prevalence of LAE in non-exposed, fetal, early, middle and late childhood exposed groups was 55 (10.8%), 38 (11.2%), 88 (18.1%), 102 (16.7%) and 109 (19.0%), respectively. Compared to the non-exposed group, the ORs for LAE were in fetal (OR = 0.956, 95% CI = 0.605-1.500, P = 0.847), late (OR = 1.748, 95% CI = 1.208-2.555, P = 0.003), middle (OR = 1.647, 95% CI = 1.140-2.403, P = 0.008) and early (OR = 1.630, 95% CI = 1.116-2.399, P = 0.012) childhood exposed groups after adjusting potential cofounders. When stratified by gender, smoking, body mass index, hypertension and diabetes, we found that the effect of famine exposure on LAE was only modified by diabetes (Pinteraction = 0.007). CONCLUSIONS: Famine exposure during childhood stage might increase the risk of LAE in adults, and this effect interacts with diabetes.

As a severe and highly contagious infection, coronavirus disease (COVID-19) affects all aspects of society and has become a global public health problem. Because of the complexity of the pathology of COVID-19, it is difficult to treat. An increasing number of reports have indicated that COVID-19 may have neurological complications, including stroke. The nervous system complications of COVID-19 have gradually attracted research attention. In this review, we summarize the latest findings related to COVID 19, elaborate on the possible mechanism of COVID 19 related onset of stroke, and summarize current treatment options because an improved understanding and appropriate treatments may improve the prognosis of patients with COVID-19-related stroke.

Objective: To establish the nutrition literacy core items for Chinese pregnant women. Methods: The framework system and preliminary items of nutrition literacy were established through literature review and experts consultation. E-Delphi method was used to determine the nutrition literacy items.11 experts in the field of maternal and child nutrition, obstetrics and gynecology, health education and nutrition and diseases were invited to score the importance of each nutrition literacy item via Email. The judgment basis and familiarity of experts towards the items, active coefficient, authority coefficient and harmony coefficient were evaluated and analyzed to generate the final list of nutrition literacy items. Results: The active coefficients of consultation in two rounds were 81.8% (9/11) and 87.5% (8/9).The authority coefficients were (0.86±0.11) and (0.85±0.06).The average scores of importance were (4.32±0.84) and (4.58±0.57) and the harmony coefficients were 0.387 (χ²=90.472, P<0.001) and 0.290 (χ²=46.752, P=0.002) respectively. After the second round of consultation, all selected items met the inclusion criteria. We identified the final list of nutrition literacy items consisting of 3 scales (basic knowledge and concept, lifestyles and dietary behaviors, and basic skills), 10 sub-scales (basic nutrition concept, food and nutrition knowledge, nutrition and disease knowledge, lifestyles, dietary behaviors, preparation for breastfeeding, gestational weight management, gestational disease management, acquisition, understanding and application of nutrition information, judgement of nutrition information, and nutrition decision making) with 24 items in total. Conclusions: The framework system and core items of nutrition literacy are established for Chinese pregnant women based on E-Delphi method. The experts involved in the consultation process present a performance with good representativeness, enthusiasm and authority. All experts' opinions are coordinated and unified, which could satisfy the demand of developing nutrition literacy core items for target population.

Objective: To establish the nutrition literacy core items for Chinese lactating women. Methods: The framework system and preliminary items of nutrition literacy were established through literature review and experts consultation. E-Delphi method was used to determine the nutrition literacy items. 11 experts in the field of maternal and child nutrition, obstetrics and gynecology, health education and nutrition and diseases were invited to score the importance of each nutrition literacy item via Email. The judgment basis and familiarity of experts towards the items, active coefficient, authority coefficient and harmony coefficient were evaluated and analyzed to generate the final list of nutrition literacy items. Results: The active coefficients of consultation in two rounds were 81.8% (9/11) and 87.5% (8/9). The authority coefficients were (0.86±0.11) and (0.85±0.06). The average scores of importance were (4.03±1.24) and (4.64±0.50)and the harmony coefficients were 0.556 (χ²=163.42, P<0.001) and 0.40 (χ²=64.41, P<0.001). After the second round of consultation, all selected items met the inclusion criteria. We identified the final list of nutrition literacy items consisting of 3 scales (basic knowledge and concept, lifestyles and dietary behaviors, and basic skills), 10 subscales (basic nutrition concept, food and nutrition knowledge, feeding knowledge, lifestyles, dietary behaviors, feeding behaviors, weight management, complementary food production, acquisition, understanding and application of nutrition information, judgement of nutrition information, and nutrition decision making) with 24 items in total. Conclusions: The framework system and core items of nutrition literacy were established for Chinese lactating women based on E-Delphi method. The experts involved in the consultation process presented a performance with good representativeness, enthusiasm and authority. All experts' opinions are coordinated and unified, which could satisfy the demand of developing nutrition literacy core items for target population.
