Shared decision-making and its influencing factors among parents of children with cancer in China: A cross-sectional study.

PURPOSE: This study aimed at exploring SDM implementation and its influencing factors, and preferences towards SDM among parents of children with cancer in China. DESIGN AND METHODS: This cross-sectional study recruited 204 participants from 2 grade-A tertiary hospitals in Guangzhou, China. The preferences towards decision-making, the status of SDM were measured by CPS-P and SDM-Q-9. The nurse support were measure by NPST, the needs of parents were measured by Questionnaire for Needs of Parents Whose Children are in PICU, and sociodemographic and disease-related questionnaires were used to investigate general information of children and parents. Descriptive statistics, univariate analysis, and multivariable linear regression were used for data analysis. RESULTS: Of 204 participants, about half of parents (55.4 %) tended to choose SDM, however, 40.2 % of them still show passive attitudes. The mean SDM-Q-9 score was 31.07 ± 8.74, and the result showed that age (ß = 2.480, P＜0.05), relapse (ß = 4.407, P＜0.01), course of disease (ß = -5.213, P＜0.01), relationships with doctors (ß = -4.05, P＜0.05), trust in doctors (ß = -2.796, P＜0.05), and communication and information support from nurses (ß = 0.651, P＜0.01) were the main factors influencing SDM for parents. CONCLUSIONS: Over half of Chinese parents tended to choose SDM, but their real participation in SDM is unsatisfactory. Parents who were older, had good relationships with doctors, trusted in doctors, received more communication and information support from nurses, and whose children had shorter course of disease, suffered relapses, participated in SDM better.

Predictors of posttraumatic growth in 475 Chinese parents of children newly diagnosed with autism spectrum disorder.

PURPOSE: To examine the predictive effects of children's symptom severity, rumination, parental self-efficacy, and social support on posttraumatic growth (PTG) in parents of autistic children. DESIGN AND METHODS: Parents (n = 475) completed the demographic questionnaire, Posttraumatic Growth Inventory, Autism Behavior Checklist, Event Related Rumination Inventory, Parenting Sense of Competence, and Social Support Rating Scale in a cross-sectional survey conducted in a tertiary hospital in Guangzhou, China, between September 2019 and January 2021. Multiple linear regression analyses were conducted using SPSS version 25.0. RESULTS: The PTG score was positively associated with rumination (r = 0.325, P < 0.05), parental self-efficacy (r = 0.219, P < 0.05), and social support (r = 0.374, P < 0.05). Multiple linear regression analysis revealed that household income (ß = 0.095, P < 0.05), intrusive rumination (ß = -0.100, P < 0.05), deliberate rumination (ß = 0.391, P < 0.001), subjective support (ß = 0.239, P < 0.001), and children's daily living skills deficiencies as perceived by parents (ß = 0.107, P < 0.05) significantly predicted PTG, accounting for 33.3% of the variance [F(P) = 13.444, P < 0.001]. CONCLUSIONS: Psychosocial factors (rumination and subjective support) are essential to facilitate PTG in parents whose children are newly diagnosed with autism. PRACTICE AND IMPLICATIONS: With the consideration of different sociodemographic features, clinicians and researchers are encouraged to explore cognitive-based psychosocial interventions targeting parents' psychological growth and parenting training programs targeting autistic children's self-care ability.

Longitudinal plasma magnesium status during pregnancy and the risk of gestational diabetes mellitus: a prospective cohort study.

Emerging evidence has shown that magnesium (Mg) was associated with type 2 diabetes while few focused on abnormal glucose metabolism during pregnancy. The study is aimed at investigating the association between longitudinal changes in plasma Mg during pregnancy and subsequent risk of gestational diabetes (GDM) and exploring the possible influence of iron supplementation on the changes of plasma Mg levels. One thousand seven hundred fifty-six pregnant women from Tongji Maternal and Child Health Cohort (TMCHC) were involved. Blood samples were collected at gestational weeks 17.0 ± 0.9 and later 26.2 ± 1.4. Plasma Mg was measured by inductively coupled plasma mass spectrometry (ICP-MS) with decline rates calculated. Information on general characteristics and iron supplementation was collected by questionnaires. Oral glucose tolerance test (OGTT) was conducted at 24-28 gestational weeks to diagnose GDM. Poisson regression with robust error variance was used to estimate relative risks (RR) of GDM. Median concentrations of plasma Mg were 0.69 mmol/L and 0.63 mmol/L respectively at two collections. The prevalence of hypomagnesemia at the first collection was 73% and associated with a 1.59 (95%CI: 1.07, 2.37) fold risk of GDM. Adjusted RRs were 1.74 (95%CI: 1.06, 2.83) and 2.44 (95%CI: 1.54, 3.85) for women with hypomagnesemia and followed more tertile (T2 and T3 vs. T1) of Mg decrement. Iron supplementation above 30 mg/day was found associated with more Mg decrement (25.5% and 27.5% in T2 and T3 vs. 19.5% in T1). In conclusion, hypomagnesemia during pregnancy is prevalent and associated with increased GDM risk, especially in women followed by more plasma Mg decrement during pregnancy. High-dose iron supplementation may involve more plasma Mg decrement.

Association of elevated mid-pregnancy maternal plasma ferritin concentrations and triglyceride concentrations with the risk of gestational diabetes mellitus: A prospective cohort study.

OBJECTIVE: Ferritin levels are well known to be associated with gestational diabetes mellitus (GDM). However, the association of the combination of ferritin and triglyceride (TG) levels in early mid-pregnancy with GDM has not been studied in depth. We investigated the independent and combined relationships of plasma ferritin and TG concentrations with the risk of GDM as well as the mediation effect of TG on ferritin. METHODS: We analysed 2071 pregnant women from the Tongji Maternal and Child Health Cohort who had their plasma ferritin and TG concentrations measured at 11-20 weeks of gestation. Associations between ferritin and TG concentrations and GDM risk were estimated using multivariable logistic regression models. Youden's index was calculated to find the cut-off values of ferritin and TG by ROC curve analysis. The mediation effect of the TG concentration on the ferritin level with GDM risk was explored by a mediation analysis. RESULTS: A total of 264 (12.3%) participants developed GDM. The median and IQR of ferritin was 53.9 (30.5-92.7) ng/mL. After adjusting for potential confounders, the relative risks (RRs) and 95% confidence intervals of GDM were 2.19 (1.42, 3.39) for ferritin and 2.02 (1.37, 2.97) for TG. The adjusted RR for combination was 2.40 (1.62, 3.55). Moreover, we found that the TG concentration mediated 15.0% of the total effect of the ferritin concentration on the risk of GDM. CONCLUSIONS: Women with a combination of both high plasma ferritin (˃55.7 ng/mL) and high TG (˃1.9 mmoL/L) were at the highest risk of GDM. Additionally, we have revealed for the first time that an elevated maternal TG concentration in early pregnancy mediates the relationship between ferritin concentration and GDM risk. TRIAL REGISTRATION: This trial is registered at https://ClinicalTrials.gov as NCT03099837.

Plasma Manganese Levels and Risk of Gestational Diabetes Mellitus: A Prospective Cohort Study.

Manganese (Mn) intake has been found to be linked with risk of type 2 diabetes. However, the role of Mn in the development of gestational diabetes mellitus (GDM) remains to be investigated. This prospective study included pregnant women from the Tongji Maternal and Child Health Cohort. A total of 2327 participants with plasma specimens before 20 weeks were included. Among the pregnant women, 9.7% (225/2327) were diagnosed with GDM. After adjustment, pregnant women with the third and highest quartile of plasma Mn levels had 1.31-fold (RR, 2.31 [1.48, 3.61]) and 2.35-fold (RR, 3.35 [2.17, 5.17]) increased risk of GDM compared with those with the lowest quartile. A 1 standard deviation increment of ln-transformed plasma Mn levels (0.53 µg/L) was related to elevated risks of GDM with RRs of 1.28 [1.17, 1.40]. The positive associations between Mn and GDM remained consistent in all the subgroups. The weighted quantile sum index was significantly related to GDM (RR, 1.60 [1.37, 1.86]). The contribution of Mn (58.69%) to the metal mixture index was the highest related to GDM. Higher plasma Mn levels were found to be linked with elevated fasting and 2 h post-load blood glucose. This study revealed relationships of higher plasma Mn levels in early pregnancy and increased risk of GDM, suggesting that though essential, excess Mn in the body might be a potential important risk factor for GDM.

Consensus on Quality Indicators for Pediatric Oncology Nursing Care in Mainland China: A Delphi Method and Analytic Hierarchy Process.

Background: Because routine nursing quality indicators are not suitable to evaluate pediatric oncology nursing care, this study aimed to identify a set of quality indicators for pediatric oncology nursing care in mainland China. Method: This prospective investigation utilized a modified Delphi technique and an analytic hierarchy process. A survey questionnaire was developed using a literature review and semi-structured interviews. Fifteen invited experts evaluated the importance of potential indicators through three rounds of Delphi survey by email in 2018. The importance weight of each indicator was identified through analytic hierarchy process. Results: In the Delphi survey, the average authoritative coefficient was 0.93-0.96 for each round of the inquiry. After three rounds of survey, 29 quality indicators were identified as important nursing outcomes for assessing the quality of pediatric oncology nursing care in mainland China. The importance rating mean score of indicators ranged between 4.67 and 5.00 on a 5-point scale, and the variation coefficient ranged between 0 and 0.19. Expert-assigned indicator importance weight varied between 0.0040 and 0.0870. Conclusion: This study identified an indicator system with 29 nursing-sensitive quality indicators that may represent potential indicator candidates for quality assessment of pediatric oncology nursing practice in mainland China.

Posttraumatic growth and rumination among parents of children with autism spectrum disorder: The mediating role of social support.

Although rumination and social support are regarded as essential predictors of posttraumatic growth (PTG), few studies have explored the associations among PTG, rumination, and social support in parents of children with autism spectrum disorder (ASD). This study examined whether social support mediates the relationship between rumination and PTG. Cross-sectional questionnaire data were collected from 385 parents of children with ASD from September 2019 to November 2020 by convenience sampling. Participants completed the Posttraumatic Growth Inventory, Event Related Rumination Inventory, and Social Support Rating Scale. Path analyses showed that subjective support partially mediates the relationship between deliberate rumination and PTG (ß = 0.073, P < 0.001), and indirect effects account for 15.30% of the total effects. In addition, a negative direct path was found between intrusive and PTG because of the suppression effect of subjective support (ß = -0.110, P < 0.01), and indirect effects accounted for 80% of the direct effects. For future studies, it underscores the essential role of subjective support and rumination in promoting PTG in parents of children with ASD.

Effectiveness of the combination of workshops and flipped classroom model to improve tube fixation training for nursing students.

BACKGROUND: Tube indwelling is a key procedure in modern medicine. Careful tube setup is necessary to prevent unplanned extubation. The training for tube fixation is time- and resource-consuming, and optimal modes of training are currently being sought. Previous studies have compared workshops and flipped classroom models separately using conventional teaching strategies, but no study has examined a combination of both teaching models in nursing training. AIM: To compare the effectiveness of workshops vs workshops combined with the flipped classroom model for improving tube fixation training for nursing students. METHODS: This was a prospective cohort study. In this study, 149 nurses who joined our hospital in 2019 underwent training using workshops combined with the flipped classroom model (experimental group), while 159 nurses who joined the hospital in 2018 received only workshop-based training (control group). The combination of workshops with the flipped classroom training model was divided into two modules: pre-class and in-class training. The participation of nurses in the training activities, on-site assessment of training, nurses' evaluation of their training, and related indicators of tube quality management were evaluated. RESULTS: The average age of nurses in the control group was 22.94 ± 0.94 years and that of nurses in the experimental group was 25.42 ± 3.23 years (P < 0.01). The qualified rate of after-class assessments for the experimental and control groups was 100.00% (average score: 94.01 ± 2.78 points) and 91.82% (average score: 84.24 ± 2.94 points), respectively (P < 0.01). Most nurses in the experimental group completely agreed that the combined training was helpful to cultivate clinical thinking and independent learning ability and to master knowledge of tube fixation. In addition, the training content within the pre-class teaching video, pre-class tube atlas, pre-class main instructor guidance, in-class demonstration, and in-class practice was very informative. The experimental group had higher evaluation scores than the control group (4.88 ± 0.38 vs 4.67 ± 0.64; P < 0.01). Comparison of tube quality management before and after training in 2018 to 2019 revealed that the unplanned ureteral tube removal rate dropped from 0.25‰ to 0.06‰, the unplanned chest tube removal rate dropped from 1.07‰ to 0.78‰, and the unplanned gastric tube removal rate dropped from 0.36‰ to 0.17‰. The incidence rate of pressure ulcers caused by the tube decreased from 0.78‰ to 0.45‰. CONCLUSION: The combination of workshop and flipped classroom training is effective in improving tube fixation training of nurses, cultivating nurses' active learning abilities and clinical thinking, and improving the safety of the procedure.

Symptom severity and posttraumatic growth in parents of children with autism spectrum disorder: The moderating role of social support.

Parents of children with autism spectrum disorder (ASD) experience posttraumatic growth (PTG). No study has investigated the moderating effect of social support and family function between symptom severity and PTG. The study aims to examine whether social support and family function moderate the relationship between symptom severity and PTG among parents of children with ASD. Using a cross-sectional design, a total of 385 parents of children with ASD were recruited from September 2019 to November 2020 by convenience sampling. Participants completed the Posttraumatic Growth Inventory, Social Support Rating Scale, Autism Behavior Checklist, and Family Apgar Index. Both social support (r = 0.354, p < 0.01) and family function (r = 0.379, p < 0.05) were significantly related to PTG. Although symptom severity was not significantly related to PTG (p > 0.05), social support moderated the correlation between symptom severity and PTG [ß(SE) = -0.134 (0.719), p < 0.01, 95% CI = (-3.552, -0.723)]; the positive association was stronger for low social support [ß(SE) = 0.145 (0.054), t = 2.675, p < 0.01, 95% CI = (0.038, 0.252)], while the negative association was weaker for high social support [ß(SE) = -0.121 (0.051), t = -2.378, p < 0.05, 95% CI = (-0.221, -0.021)]. Family function did not moderate the relationship (p > 0.05). Higher social support appears to buffer the detrimental effect of symptom severity on PTG, and social support seems to be an important factor when delivering interventions aimed at decreasing symptom severity and improving positive growth. LAY SUMMARY: Both social support and family function were positively associated with PTG. Providing sufficient perceived social support and enhancing family function promoted parents' positive psychological experience. Higher social support seemed to buffer the detrimental effect of symptom severity on PTG, and it could be an important intervention target for improving the psychological growth of parents of children with ASD.

Individual, Interpersonal, and Home Environmental Factors Influencing Health Behaviors Among Chinese Childhood Cancer Survivors: A Structural Equation Analysis.

BACKGROUND: Childhood cancer survivors (CCSs) are at increased risk of chronic health conditions, which could be controlled with health behaviors. However, the health behaviors and related factors of Chinese CCSs remain unclear. OBJECTIVE: The aims of this study were to examine multiple health behaviors among Chinese CCSs and explore the individual, interpersonal, and home environmental factors affecting health behaviors. METHODS: This cross-sectional study recruited 204 participants from 3 grade-A tertiary hospitals in Guangzhou, China. Participants provided data on health behaviors (smoking, drinking, drug use, screen time, internet addiction, dietary behaviors, physical activity, and sleep behaviors) and their determining factors. Structural equation modeling was used to analyze the data. RESULTS: Chinese CCSs reported low rates of smoking, drinking, and drug use (0%-6.4%), but only 51% of survivors met screen time recommendations, and 24.5% of them had Internet addiction. Few survivors reported frequent soft-drink, sugar, and fast-food intake (2.0 to 7.4%), but many were finicky eaters (55.4%) or seldom drank milk (41.7%). In addition, 67.6% and 47.5% of survivors did not meet physical activity and sleep time recommendations. Childhood cancer survivors' health behaviors were influenced by the individual (age, education level, and time since diagnosis), interpersonal (peer and family support), and home environmental (residential location, parents' educations level, and household income) factors. CONCLUSIONS: There were suboptimal health behaviors among Chinese CCSs. Targeted interventions should consider their individual, interpersonal, and home environmental factors. IMPLICATIONS FOR PRACTICE: Knowledge of health behaviors and related factors of Chinese CCSs would help healthcare professionals develop further interventions to improve their care of this population.

Parental self-efficacy and family quality of life in parents of children with autism spectrum disorder in China: The possible mediating role of social support.

OBJECTIVE: This study explored the related factors of FQOL in parents of children with ASD and examined whether social support mediates the relationship between parental self-efficacy and FQOL in parents of children with ASD. DESIGN AND METHODS: Using a cross-sectional design, a total of 260 parents of children with ASD were recruited from September 2019 to November 2020. They completed the Beach Center Family Quality of Life Scale, the Parenting Sense of Competence Scale, and the Social Support Rating Scale. RESULTS: Parental self-efficacy and social support explained approximately 49.5% of the variance in FQOL. After controlling for the confounding influence of parents' education level, parental self-efficacy had a direct effect on FQOL (ß = 0.292, SE = 0.108, P < 0.01) and an indirect effect on FQOL (ß = 0.165, SE = 0.069, P < 0.01). Effects were mediated through social support, with partial mediating effects accounting for 36.11% of the total effect. CONCLUSIONS: Both parental self-efficacy and social support are critical to promoting FQOL, and a partial mediating effect of social support was established. PRACTICAL IMPLICATIONS: Interventions for families with children with ASD should focus on enhancing parental self-efficacy, followed by a perceived social support and FQOL prompt.

Association of Maternal Dietary Patterns With Birth Weight and the Mediation of Gestational Weight Gain: A Prospective Birth Cohort.

The associations among maternal diet, birth weight, and gestational weight gain are still inconclusive. This study aimed to investigate the associations between maternal dietary patterns and birth weight, and further explore whether GWG mediates these associations. A total of 3,334 pregnant women who completed a validated semi-quantitative food frequency questionnaire from the Tongji Maternal and Child Health Cohort were included. Dietary patterns were extracted by using principal component analysis. Regression models and mediation analyses were performed to explore the associations between dietary patterns and birth weight and the effects of GWG on these associations. Five dietary patterns were identified: "Beans-vegetables," "Fish-meat-eggs," "Nuts-whole grains," "Organ-poultry-seafood" and "Rice-wheat-fruits." Only women following the "Beans-vegetables" pattern had heavier newborns (ß = 47.39; 95% CI: 12.25, 82.54). Women following the "Beans-vegetables" pattern had significantly lower GWG (ß = -0.7; 95% CI: -1.15, -0.25) and had a 16% lower risk of excessive GWG and 11% higher odd of adequate GWG. The association between the "Beans-vegetables" pattern and birth weight was negatively mediated by GWG. A dietary pattern enriched in beans and vegetables is beneficial for effectively controlling GWG and increasing birth weight. GWG serves. Clinical Trial Registry: This trial was registered at ClinicalTrials.gov (NCT03099837).

Association between maternal plasma ferritin concentration, iron supplement use, and the risk of gestational diabetes: a prospective cohort study.

BACKGROUND: The association between iron supplementation and gestational diabetes mellitus (GDM) is still inconclusive, and this association has not been extensively studied in relation to plasma ferritin in the early second trimester. OBJECTIVES: We aimed to prospectively examine the independent and combined associations of plasma ferritin concentrations and iron supplement use with GDM. METHODS: We studied 2117 women from the Tongji Maternal and Child Health Cohort in Wuhan, China. Plasma ferritin around 16 weeks' gestation was measured by ELISA kits and information on iron supplement use was collected by questionnaires. GDM was diagnosed by a 75-g oral-glucose-tolerance test (OGTT) at 24-28 weeks' gestation. A log-Poisson regression model was used to estimate the RR of GDM associated with plasma ferritin and iron supplementation. RESULTS: The median and IQR of plasma ferritin was 52.1 (29.6-89.9) ng/mL, and 863 (40.8%) participants reported use of iron supplements during the second trimester. A total of 219 (10.3%) participants developed GDM. Adjusted RRs (95% CIs) for GDM across increasing quartiles of plasma ferritin were 1.00 (reference), 2.14 (1.37, 3.34), 2.03 (1.30, 3.19), and 2.72 (1.76, 4.21), respectively. After adjustment, supplemental iron ≥60 mg/d during the second trimester was associated with an increased risk of GDM compared with nonusers (RR: 1.37; 95% CI: 1.02, 1.84). CONCLUSIONS: Both elevated plasma ferritin concentrations in the early second trimester and use of ≥60 mg/d of supplemental iron during pregnancy are independently associated with increased risk of GDM. Further clinical trials with precision nutrition approaches considering both baseline iron status and supplement use are needed to evaluate the benefits and risks of iron supplementation during pregnancy.

Association between Chinese Dietary Guidelines Compliance Index for Pregnant Women and Risks of Pregnancy Complications in the Tongji Maternal and Child Health Cohort.

BACKGROUND: Compliance with dietary guidelines among pregnant women can positively influence not only their own health but also the health of their babies. Measuring the compliance requires professional skills in nutrition and dietary counseling. In China, few simple and effective techniques assess dietary quality among pregnant women, especially in rural areas. We aimed to establish a new simple and effective assessment technique, the "Chinese Dietary Guidelines Compliance Index for Pregnant Women (CDGCI-PW)" and assess the association between maternal dietary compliance and risks of pregnancy complications. METHODS: The CDGCI-PW consists of 13 main components which were based on the 2016 edition of the Chinese dietary guidelines for pregnant women. Each component was assigned a different score range, and the overall score ranged from 0 to 100 points. The Tongji Maternal and Child Health Cohort study (from September 2013 to May 2016) was a prospective cohort study designed to examine maternal dietary and lifestyle effects on the health of pregnant women and their offspring. The maternal diet during the second trimester was compared with the corresponding recommended intake of the Chinese balanced dietary pagoda for pregnant women to verify their compliance with dietary guidelines. The association between maternal dietary quality and risks of pregnancy complications was estimated by regression analysis. Receiver operating characteristic (ROC) curves were constructed to identify the optimal cut-off values of CDGCI-PW for gestational hypertension and gestational diabetes mellitus (GDM). RESULTS: Among the 2708 pregnant women, 1489 were eventually followed up. The mean CDGCI-PW score was 74.1 (standard deviation (SD) 7.5) in the second trimester. The majority of foods showed the following trend: the higher the CDGCI-PW score, the higher the proportion of pregnant women who reported food intake within the recommended range. Moreover, a higher maternal CDGCI-PW score was significantly associated with lower risks of gestational hypertension [odds ratio (OR) (95% confidence interval [(CI): 0.30 (0.20, 0.37)] and GDM [OR (95% CI): 0.38 (0.31, 0.48)]. The optimal CDGCI-PW cut-off value for gestational hypertension was ≥68.5 (sensitivity 82%; specificity: 61%; area under the ROC curve, AUC = 0.743), and the optimal CDGCI-PW cut-off score for GDM was ≥75.5 (sensitivity 43%; specificity: 81%; area under the ROC curve, AUC = 0.714). CONCLUSIONS: The CDGCI-PW is a simple and useful technique that assesses maternal diet quality during pregnancy, while adherence to the CDGCI-PW is associated with a lower risk of gestational hypertension and GDM.

Association between dietary inflammatory index and gestational diabetes mellitus risk in a prospective birth cohort study.

OBJECTIVE: Information is limited regarding the possible relationship between diet-related inflammation and the risk of gestational diabetes mellitus (GDM). This study investigated the association between the inflammatory potential of the diet, measured by the dietary inflammatory index (DII), and GDM risk in pregnant Chinese women. METHODS: This study included 2639 eligible women from the Tongji Maternal and Child Health Cohort. Dietary intake was assessed by a validated semiquantitative food frequency questionnaire and was used to calculate the DII score. The DII was then validated using C-reactive protein measurements in a subsample of 133 pregnant women. GDM diagnoses were collected from medical records based on the results of a 75 g oral glucose tolerance test at 24 to 28 wk gestation. Multivariable-adjusted logistic regression models were performed to estimate the odds ratios (ORs) for GDM risk by DII score, modeled continuously and in tertiles. RESULTS: Of the 2639 participants, 13.1% were diagnosed with GDM. DII scores ranged from -4.45 to 3.15 and were positively associated with C-reactive protein (adjusted ß : 1.28, 95% confidence interval [CI]: 0.16, 2.40; P trend = 0.023) when comparing DII tertile 3 (most pro-inflammatory) to tertile 1 (most anti-inflammatory). A significant and positive association was observed between DII scores and GDM risk (adjusted OR: 1.43; 95% CI: 1.05, 1.95; P trend = 0.022) comparing the highest versus lowest tertiles. The stratified analysis showed that this association was stronger in pregnant women who were overweight or obese before pregnancy (adjusted OR: 2.20; 95% CI: 1.03, 4.69). CONCLUSIONS: These findings suggest that a higher DII score, corresponding to a more proinflammatory diet, is associated with a higher risk of GDM, particularly in pregnant women who were overweight or obese before pregnancy.

The overall plant-based diet index during pregnancy and risk of gestational diabetes mellitus: a prospective cohort study in China.

The high overall plant-based diet index (PDI) is considered to protect against type 2 diabetes in the general population. However, whether the PDI affects gestational diabetes mellitus (GDM) risk among pregnant women is still unclear. We evaluated the association between PDI and GDM risk based on a Chinese large prospective cohort - the Tongji Maternal and Child Health Cohort. Dietary data were collected at 13-28 weeks of pregnancy by a validated semi-quantitative FFQ. The PDI was obtained by assigning plant food groups positive scores while assigning animal food groups reverse scores. GDM was diagnosed by a 75 g 2-h oral glucose tolerance test at 24-28 weeks of gestation. Logistic regression models were fitted to estimate OR of GDM, with associated 95 % CI, comparing women in different PDI quartiles. Among the total 2099 participants, 169 (8·1 %) were diagnosed with GDM. The PDI ranged from 21·0 to 52·0 with a median of 36·0 (interquartile range (IQR) 33·0-39·0). After adjusting for social-demographic characteristics and lifestyle factors etc., the participants with the highest quartile of PDI were associated with 57 % reduced odds of GDM compared with women in the lowest quartile of PDI (adjusted OR 0·43; 95 % CI 0·24, 0·77; Pfor trend = 0·005). An IQR increment in PDI was associated with 29 % decreased odds of GDM (adjusted OR 0·71; 95 % CI 0·56, 0·90). Findings suggest that adopting a plant-based diet during pregnancy could reduce GDM risk among Chinese women, which may be valuable for dietary counselling during pregnancy.

Predictive risk scales for development of pressure ulcers in pediatric patients admitted to general ward and intensive care unit.

BACKGROUND: More than ten special scales are available to predict the risk of pressure ulcers in children. However, the performances of those scales have not yet been compared in China. AIM: To compare the Waterlow, Braden Q, and Glamorgan scales, and identify more suitable pressure ulcer evaluation scale for the pediatric intensive care unit (PICU). METHODS: Trained nurses used the Waterlow, Braden Q, and Glamorgan scales to assess pediatric patients at Sun Yat-sen Memorial Hospital (China) within 24 h of admission from May 2017 to December 2020 in two stages. Skin examination was carried out to identify pressure ulcers every 3 d for 3 wk. RESULTS: The incidence of pressure ulcers was 3/28 (10.7%) in the PICU and 5/314 (1.6%) in the general pediatric ward. For children in the general ward, the Waterlow, Braden Q, and Glamorgan scales had comparable area under the operating characteristic curve (AUC) of 0.870, 0.924, and 0.923, respectively, and optimal cut-off values of 14, 14, and 29 points. For PICU, the Waterlow, Braden Q, and Glamorgan scales had slightly lower AUC of 0.833, 0.733, and 0.800, respectively, and optimal cut-off values of 13, 16, and 27 points. Braden Q demonstrated a satisfactory specificity, and during the second stage of the study for PICU patients, the AUC of the Braden Q scale was 0.810, with an optimal cut-off value of 18.35 points. CONCLUSION: The Waterlow, Braden Q, and Glamorgan scales have comparable performance, while the Braden Q scale demonstrates a better specificity and can be successfully used by pediatric nurses to identify patients at high risk of pressure ulcers in PICU.

Inverse association of total polyphenols and flavonoids intake and the intake from fruits with the risk of gestational diabetes mellitus: A prospective cohort study.

BACKGROUND & AIMS: Emerging evidence has shown the inverse association between dietary polyphenols intake and type 2 diabetes mellitus risk, however, few studies focus on the prospective effects of polyphenols on gestational diabetes mellitus (GDM). Thus, the aim was to evaluate whether higher polyphenols intake and the intake from fruits and vegetables was correlated to a lower risk of GDM. METHODS: Dietary intake of polyphenols of women with a singleton pregnancy and without any history of diabetes were obtained by a validated food frequency questionnaire from Tongji Maternal and Child Health Cohort study. Oral glucose tolerance tests were conducted at 24-28 weeks to screen for GDM. Logistic regression models were used to evaluate the association between dietary intake of polyphenols, and the results were presented as odds ratios (ORs) with 95% confidence interval (CIs). Generalized linear models were adopted to determine the association of polyphenols intake with blood glucose concentrations, and the results were presented as coefficients (ß) with 95% CIs. RESULTS: 185 (8.3%) of 2231 pregnant women were diagnosed with GDM. The intake of total polyphenols was 319.9 (217.8-427.0) mg/d, and the intake from fruits and vegetables was 201.6 (115.3-281.8) mg/d and 63.2 (41.1-92.7) mg/d, respectively. Compared with the lowest quartile, the adjusted ORs (95% CIs) of GDM risk for women with the highest quartile of total polyphenols and flavonoids intake was 0.55 (0.30, 0.99), and 0.57 (0.32, 0.99). The adjusted ORs (95% CIs) of GDM risk was 0.55 0.51 (0.30, 0.87) (Pfor trend = 0.017) for polyphenols from fruits, 0.58 (0.34, 0.99) (Pfor trend = 0.038) for flavonoids from fruits, and 0.62 (0.38, 1.00) (Pfor trend = 0.065) for anthocyanidins from fruits comparing the highest versus lowest quartile. In addition, each 100 mg increase of total polyphenols and polyphenols from fruits was associated with 0.054 (0.008, 0.096) (P = 0.021) and 0.061 (0.012, 0.109) (P = 0.015) decrease in 2-h post-load blood glucose. No significant association was found between total polyphenols from vegetables intake and the risk of GDM. CONCLUSIONS: Higher dietary intake of total polyphenols and flavonoids and the intake from fruits was associated with lower GDM risk. This study was registered at clinicaltrials.gov as NCT03099837.

Dietary behaviours, physical activity and quality of life among childhood cancer survivors in Mainland China: A cross-sectional study.

OBJECTIVE: To examine the dietary behaviours, physical activity (PA) and quality of life (QoL) of childhood cancer survivors (CCS) in Mainland China and explore the relationships between these behaviours and QoL. METHODS: This cross-sectional study recruited 181 CCS from three Grade-A tertiary hospitals in Guangzhou. Survivors completed questionnaires assessing their dietary behaviours, PA and QoL. RESULTS: Only 2.2%, 7.7% and 2.2% of CCS reported frequent soft drinks, sugar and fast food intake, which were lower compared to CCS in Western studies. Most survivors (72.9%) failed to drink milk daily, and many (54.7%) were picky eating. Sixty percent of CCS reported less moderate-to-vigorous physical activity (MVPA) time than 60 min/day recommended by WHO. Picky eating was significantly associated with lower overall (p < 0.001), physical (p < 0.001) and psychosocial (p < 0.001) QoL. MVPA was significantly positively associated with overall (p < 0.05) and psychosocial (p < 0.01) QoL. CONCLUSIONS: Chinese CCS engaged better dietary behaviours of less soft drinks, sugar and fast food consumption, but many were picky eaters and did not meet milk intake and PA recommendations. Early behavioural interventions aimed at increasing the dietary diversity and MVPA level of this population should be taken to improve their QoL.
