Educational intervention based on the extended parallel process model improves adherence to diabetic diet and glycaemic control indices: a randomised, double-blind, controlled, factorial field trial.

Nutritional education is pivotal in the medical nutritional therapy of type 2 diabetes mellitus (T2DM). The extended parallel process model (EPPM) is a health education method for inducing desirable health behaviours. The present study aimed to investigate the effect of nutritional education based on the EPPM in T2DM patients on knowledge, attitude, practice, anthropometric indices, glycaemic factors, lipid profile and adherence to the diabetic diet. A randomised, double-blind, controlled, factorial field trial was designed for T2DM patients aged 30-59 years (n 88). Participants were randomly allocated into four groups to receive EPPM-based nutritional education through gain framed message (GFM), loss framed message (LFM), their combination (G\LFM) or usual diabetic education in the control group (CG). Participants were assessed before and after the study duration. After 3 months of intervention, eighty participants finished the study. The EPPM-based intervention increased participants' knowledge, behavioural intention, perceived sensitivity, severity, self-efficacy (P < 0·001 for all) and response efficacy (P = 0·029) in comparison with CG. GFM (P = 0·004) and G\FLM (P = 0·034) reduced carbohydrate intake and LFM (P = 0·034) and G\LFM (P = 0·047) decreased fat intake. Between-group analysis indicated interventions reduced weight (P = 0·046), BMI (P = 0·038), fasting blood sugar (P = 0·030), 2-hour postprandial blood glucose (P = 0·027) and TAG (P = 0·002) in comparison with the CG. Results were NS for protein intake, waist and hip circumference, waist:hip ratio, HbA1c, total cholesterol, LDL and HDL. Nutritional education based on EPPM could increase the knowledge and awareness of T2DM patients. Also, it could be beneficial for blood glucose amendment. Further investigations are recommended.

Night eating habits, sleep quality, and depression, are they associated with vitamin D status?

INTRODUCTION: In addition to the well-established roles of vitamin D on bone health, it also appears to be an effective factor on mental health and circadian behaviors, that include eating and sleeping habits. OBJECTIVE: This study aimed to assess the association between vitamin D status with night eating habits, sleep quality and depression in female college students. MATERIALS AND METHODS: This cross-sectional study studied healthy female students from Shiraz University of Medical Sciences, Iran. Demographic and anthropometric information as well as data on sleep quality and depression were recorded and serum levels of 25-hydroxyvitamin D were measured. A 3-day food record questionnaire was completed to assess night eating habits. Data analyses were undertaken using Chi-square, Mann-Whitney U test and logistic regression. A P-value of <0.05 was considered significant. RESULTS: The study participants comprised of 272 female students with median (Inter Quartile Range) age of 22 (21-24) years. The majority of the participants (82.3 %) were classified as night eaters, who had higher rates of poor sleep quality compared to non-night eaters (P < 0.05). With 1 ng/ml increase in serum levels of 25-hydroxyvitamin D, the odds of being a night eater fell by 3 % (OR = 0.97; 95%CI = 0.95, 0.99), and the odds of having depression or poor sleep quality decreased by 5 % (OR = 0.95; 95%CI = 0.93, 0.97) and 6 % (OR = 0.94; 95%CI = 0.91, 0.97), respectively. CONCLUSION: There was an inverse association between serum 25-hydroxyvitamin D level with night eating habits, depression and poor sleep quality. This association needs be confirmed using cohort and interventional studies.

Effect of carotenoid supplementation on blood pressure in adults: a GRADE-assessed systematic review and dose-response meta-analysis of randomized controlled trials.

CONTEXT: Hypertension (HTN) is regarded as a serious public health issue throughout the world. High blood pressure (BP) may be improved by carotenoid supplementation; however, randomized controlled trials (RCTs) provide conflicting evidence. OBJECTIVE: The aim of this study was to evaluate the effects of carotenoid supplementation on BP in RCTs by systematically review and meta-analysis. DATA SOURCES: A comprehensive literature search was performed in the Scopus, PubMed, and Web of Science databases until October 2023, with no limitation on the date or language of publication. DATA EXTRACTION: Studies that evaluated the net effects of carotenoids in the form of supplements on BP in adults were selected. Weighted mean differences (WMDs) and 95% confidence intervals (CIs) were calculated on the basis of a fixed or random-effects model. Sensitivity analysis, meta-regression, publication bias, and heterogeneity were assessed using standard methods. Cochrane quality assessments were used to evaluate the included studies' bias risks. Evidence certainty was calculated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework). DATA ANALYSIS: Reports on a total of 19 RCTs involving 1151 participants were included in this review. Carotenoid supplementation significantly reduced the systolic BP (SBP) (WMD, -2.492 mmHg; 95%CI, -4.52, -0.47; P = 0.016) and diastolic BP (DBP) (WMD, -1.60 mmHg; 95%CI, -2.73, -0.47; P = 0.005). Greater effects were observed in Asian participants, those aged >50 years, nonhealthy participants, and participants with a baseline SBP ≥130 mmHg and DBP ≥80 mmHg, at dose >10 mg. Dose-response analysis showed that carotenoid supplementation decreased SBP and DBP levels at doses of, respectively, 0-25 and 0-20 mg/d. Evidence for all SBP, DBP, and heart rate values was high quality. CONCLUSIONS: Carotenoid supplementation had a beneficial effect on BP parameters, especially in nonhealthy study participants with high BP baseline levels. PROSPERO REGISTRATION NO: CRD42023402740.

A Systematic Review and Meta-Analysis of Vitamin D Status of Patients with Severe Obesity in Various Regions Worldwide.

INTRODUCTION: Managing nutritional deficiencies is an essential component in the treatment of severe obesity. Vitamin D deficiency is often reported in investigations in severely obese cohorts. However, no prior study has summarized findings on this topic. Consequently, the aim of this systematic review and meta-analysis was to investigate the 25-hydroxyvitamin D [25(OH)D] status in individuals with severe obesity in different regions worldwide. We also evaluated levels of calcium, parathyroid hormone (PTH), and magnesium as secondary outcome measures. METHODS: We searched Medline, PubMed, Scopus, the Cochrane Library, and EMBASE for relevant observational studies published in English from 2009 to October 2021. The heterogeneity index among the studies was determined using the Cochran (Q) and I2 tests. Based on the heterogeneity results, the random-effect model was applied to estimate the prevalence of vitamin D deficiency. RESULTS: We identified 109 eligible observational studies. Overall, 59.44% of patients had vitamin D deficiency [25(OH)D <20 ng/mL], whereas 26.95% had vitamin D insufficiency [25(OH)D 20-30 ng/mL]. Moreover, the mean 25(OH)D level was 18.65 ng/mL in 96 studies. The pooled mean estimate of the serum calcium, PTH, and magnesium was 9.26 mg/dL (95% confidence interval [CI]: 9.19-9.32, I2 = 99.7%, p < 0.001), 59.24 pg/mL (95% CI: 54.98, 63.51, I2 = 99.7%, p < 0.001), and 0.91 mg/dL (95% CI: 0.84, 0.98, I2 = 100.0%, p < 0.001), respectively. The results of the subgroup analysis indicated that the mean estimates of 25(OH)D were highest in North America (21.71 ng/mL [19.69, 23.74], [I2 = 97.2%, p < 0.001]) and lowest in Southeast Asia (14.93 ng/mL [14.54, 15.33], [I2 = 0.0%, p = 0.778]). CONCLUSION: The results obtained showed a significant prevalence of vitamin D deficiency among severely obese individuals in various geographical regions, whereas the highest and lowest mean estimates were reported for North America and Southeast Asia, respectively.

Investigation of the Relationship Between Religious Attitude and Postpartum Physical and Perineal Pain in Iran.

Postpartum pain is one of the most important and common problems of postpartum mothers who resort to non-pharmacological strategies to relieve it due to the side effects of painkillers. This study was conducted to investigate the relationship between religiosity and postpartum physical and perineal pain. The sample size in this cross-sectional study was 101 women giving birth in educational and medical centers of Shiraz, Iran, that was selected by purposive-convenience sampling. Then, a questionnaire was completed for each of them including demographic characteristics, religious attitude, and visual scale of postpartum pain. Data were analyzed by SPSS software. The frequency of the majority of the research population was found at moderate religious attitudes 65.4% (72 individuals). There is a positive and Statistical inverse correlation between religious attitude and perineal pain. According to Fisher's test, in mothers with a high religious attitude, 9.7% had severe perineal pain, 41.9% had moderate pain, and 48.4% had mild pain (p = 0.001). Besides, in the case of physical pain, 3.2%, 35.5%, and 61.3% had severe, moderate, and mild pain, respectively. Regarding physical pains, with the increase in the level of mothers' religious attitude, physical pains also decreased, but the statistical relationship was not significant (p = 0.32). The results showed that the religiosity and spirituality of pregnant women have relieving effects on postpartum pain. Therefore, more attention to the spiritual dimension of human existence and planning to improve it using prayer therapy, dhikr, and meditation is suggested as a strategy to deal with the fear of pain and childbirth and reduce psychological and physical changes before and after childbirth. These findings apply to women with ectopic pregnancies in Iran.

Quality of diet and odds of metabolic syndrome in Iranian adults: Baseline results from the PERSIAN Kavar cohort study (PKCS).

BACKGROUND AND AIMS: Metabolic Syndrome (MetS) is a major risk factor for cardiovascular diseases and type 2 diabetes mellitus. Diet quality has been associated with multiple chronic diseases. We aimed to investigate the association between the quality of diet and the odds of being diagnosed with MetS. METHODS AND RESULTS: This study was conducted cross-sectionally on baseline data of 2225 individuals from the PERSIAN Kavar Cohort Study (PKCS). The quality of diet was measured based on the Diet Quality Index - International (DQI-I), using Food Frequency Questionnaires. The association between DQI-I and MetS and its components was measured via logistic regression models in crude and adjusted models. We did not observe any association between DQI-I and MetS in the overall population. However, after adjustment for potential confounders, we found that male participants with higher DQI-I scores had a lower risk of MetS [adjusted odds ratio (OR) 95% confidence interval CI) = 0.62 (0.42-0.93)]. Moreover, analogous trends were observed with respect to some components of MetS, including elevated triglyceride (TG) [crude OR (95% CI) = 0.89 (0.70-0.98); adjusted OR = 0.82 (0.65-0.93)], lowered high-density lipoprotein cholesterol (HDL-c) [crude OR (95% CI) = 0.79 (0.57-0.99); adjusted OR = 0.76 (0.55-0.97)], and abnormal glucose homeostasis [crude OR (95% CI) = 0.80 (0.55-0.94); adjusted OR = 0.73 (0.51-0.91)] only in male participants, both before and after adjustment for potential confounders. CONCLUSION: In this study, we showed that higher adherence to a high-quality diet was associated with a lower chance of developing MetS in men. Biological gender might be responsible for the observed discrepancies.

Adherence to a healthy diet and odds of metabolic syndrome: A cross-sectional study.

INTRODUCTION: Metabolic syndrome (MetS) is a major health concern around the world. Dietary factors, including diet quality, play a significant role in its pathophysiology. Healthy Eating Index (HEI) is a tool used as a valid measurement of the individual's diet quality. We aimed at investigating the relationship between diet quality as assessed by HEI-2015 and the risk of MetS and its components in a cross-sectional sample of suburban individuals from PERSIAN Kavar cohort study (PKCS), Fars province, Iran. METHODS: 2225 individuals meeting the eligibility criteria participated in the study. The relevant data were obtained from the baseline phase of PKCS. MetS was defined according to cut-offs presented by the National Cholesterol Education Program Adult Treatment Panel III (ATP III). HEI-2015 was calculated for the included individuals. Odds ratios were estimated. P-values <0.05 were considered as significant. RESULTS: The overall prevalence of MetS was 27.3%. Individuals with lower HEI-2015 scores had higher odds for MetS and its components. We observed that those who were categorized as the top HEI-2015 tertile had 42% (OR: 0.58; 95% CI: 0.38-0.90) lower odds of high blood pressure in the overall population. Also, the odds of high serum triacylglycerol was lower (OR: 0.72; 95% CI: 0.57-0.90) in those with the highest HEI-2015 scores. CONCLUSION: We found that higher dietary quality measured by HEI will decrease the risk of developing MetS, hypertension, and hypertriglyceridemia among Iranian adults. However, future interventional studies are required to further elucidate the issue.

Whey Protein Supplementation with or without Vitamin D on Sarcopenia-Related Measures: A Systematic Review and Meta-Analysis.

The effects of supplementation with whey protein alone or with vitamin D on sarcopenia-related outcomes in older adults are unclear. We aimed to assess the effect of whey protein supplementation alone or with vitamin D on lean mass (LM), strength, and function in older adults with or without sarcopenia or frailty. We searched PubMed, Web of Science, and SCOPUS databases. Randomized controlled trials (RCT) that investigated the effect of whey protein supplementation with or without vitamin D on sarcopenia outcomes in healthy and sarcopenic or frail older adults were included. Standardized mean differences (SMDs) were calculated for LM, muscle strength, and physical function data. The analysis showed that whey protein supplementation had no effect on LM and muscle strength; nevertheless, a significant improvement was found in physical function (SMD = 0.561; 95% confidence interval [CIs]: 0.256, 0.865, n = 33), particularly gait speed (GS). On the contrary, whey protein supplementation significantly improved LM (SMD = 0.982; 95% CI: 0.228, 1.736; n = 11), appendicular lean mass and physical function (SMD = 1.211; 95% CI: 0.588, 1.834; n = 16), and GS in sarcopenic/frail older adults. By contrast, co-supplementation with vitamin D enhanced LM gains (SMD =0.993; 95% CI: 0.112, 1.874; n = 11), muscle strength (SMD =2.005; 95% CI: 0.975, 3.035; n = 11), and physical function (SMD = 3.038; 95% CI: 2.196, 3.879; n = 18) significantly. Muscle strength and physical function improvements after whey protein supplementation plus vitamin D were observed without resistance exercise (RE) and short study duration subgroups. Moreover, the combination of whey protein and vitamin D with RE did not enhance the effect of RE. Whey protein supplementation improved LM and function in sarcopenic/frail older adults but had no positive effect in healthy older persons. By contrast, our meta-analysis showed that co-supplementation with whey protein and vitamin D is effective, particularly in healthy older adults, which is likely owing, we propose, to the correction of vitamin D insufficiency or deficiency. The trial was registered at https://inplasy.com as INPLASY202240167.

The association between low carbohydrate diet and odds of metabolic syndrome in adults: A cross-sectional study.

OBJECTIVE: Metabolic syndrome (MetS) has become a major health problem across the globe. Various investigations have been conducted to find the underlying lifestyle-related causes of MetS. Modifiable dietary factors are specifically the center of interest, including the macronutrient composition of the regimen. We aimed to study the association between a low-carbohydrate diet score (LCDS) with MetS and its components in a Kavarian population, located in the center of Iran. METHODS: The present study is a cross-sectional investigation conducted on a healthy sub-sample of PERSIAN Kavar cohort meeting our inclusion criteria (n = 2225). General, dietary, anthropometric, and laboratory data were obtained for each individual using validated questionnaires and measurements. Possible associations between LCDS and MetS and its components were verified using relevant statistical analyses, including analysis of variance and covariance (ANOVA and ANCOVA) and logistic regression. P-values <0.05 were considered as significant. RESULTS: Compared with the lowest LCDS tertiles, those who were assigned to the upper tertiles had lower chance of MetS, after adjusting for potential confounders (OR: 0.66; 95% CI: 0.51-0.85). Moreover, those who assigned to the top LCDS tertile had 23% (OR: 0.77; 95% CI: 0.60-0.98) and 24% (OR: 0.76; 95% CI: 0.60-0.98) lower odds of abdominal adiposity and abnormal glucose homeostasis, respectively. CONCLUSION: We observed a protective effect of low-carbohydrate diet against metabolic syndrome and its components, including abdominal obesity and abnormal glucose homeostasis. However, these initial findings need to be confirmed, especially in the format of clinical trials to ensure causality.

Association of plant-based dietary patterns with metabolic syndrome: baseline results from the Persian Kavar cohort study (PKCS).

Plant-based diets (PBDs) have gained a positive reputation among experts as a solution to combat the epidemic of MetS. A total of 2225 healthy Iranian individuals aged 35-70 years were considered eligible to be included in this cross-sectional investigation. Various dietary, anthropometric, and biochemical assessments were conducted using standard, valid methods/tools. Relevant PBD scores were calculated using three a posteriori indices, including the overall plant-based diet index (PDI), healthful PDI (hPDI), and unhealthful PDI (uPDI). Our findings showed that women with the highest adherence to hPDI had a lower chance of MetS. Also, participants in the top tertiles of hPDI were more likely to have a lower risk of low serum HDL-c and abnormal glucose homeostasis. Additionally, a significant increasing trend was observed for low serum HDL-c across tertiles of uPDI. Our observations suggest that healthful-rich plant foods may have a protective effect against MetS, especially in women.

Structural equation modeling of direct and indirect associations of social media addiction with eating behavior in adolescents and young adults.

Social media (SM) exerts important effects on health-related behaviors such as eating behaviors (EB). The present study was designed to determine the direct and indirect association of SM addiction with EB in adolescents and young adults through body image (BI). In this cross-sectional study, 12-22 years old adolescents and young adults, with no history of mental disorders or psychiatric medications usage were studied through an online questionnaire shared via SM platforms. Data were gathered about SM addiction, BI, and EB in its sub-scales. A single approach and multi-group path analyses were performed to find possible direct and indirect associations of SM addiction with EB through BI concerns. Overall, 970 subjects, 55.8% boys, were included in the analysis. Both multi-group (ß = 0.484, SE = 0.025, P < 0.001) and fully-adjusted (ß = 0.460, SE = 0.026, P < 0.001) path analyses showed higher SM addiction is related to disordered BI. Furthermore, the multi-group analysis showed one unit increment in SM addiction score was associated with 0.170 units higher scores for emotional eating (SE = 0.032, P < 0.001), 0.237 for external stimuli (SE = 0.032, P < 0.001), and 0.122 for restrained eating (SE = 0.031, P < 0.001). The present study revealed that SM addiction is associated with EB both directly and also indirectly through deteriorating BI in adolescents and young adults.

Maternal-Neonatal Attachment in Intended and Unintended Pregnancies during the First 24 Hours after Childbirth.

Introduction: Women's physical and mental health and their mortality at reproductive age depend on fertility behaviors, delivery, and its complications. Unintended pregnancy is a risk to the life of women at reproductive age. The present study aimed to compare maternal and neonatal attachment in intended and unintended pregnancies after the mother and baby skin-to-skin contact immediately after delivery (first hour) and 24 hours after that. Methods: This analytical case-control study was performed on 140 women who gave birth in the hospitals affiliated to Shiraz University of Medical Sciences, Iran. The subjects were categorized into groups of intended and unintended pregnancy. Skin-to-skin contact of the mother and baby was done for 15 minutes in the recovery room at the first hour and 24 hours after birth. Then, the Avant's questionnaire of mother-infant attachment behaviors was completed. Data were analyzed using SPSS ver.13. Results: The mean (SD) attachment score in the first hours in intended pregnancy was 84.22 (12.59), which was higher than that in unintended pregnancy 74.28 (15.81), indicating a significant difference. However, after 24 hours of delivery, there was no significant difference between the two groups. During the first hours after delivery, there was a significant difference in the total score of the emotional behaviors and care between the two groups. Conclusion: Maternal and infant skin contact during lactation increased attachment after 24 hours in unintended pregnancy, while in the first hours after delivery, attachment decreased in these pregnancies.

Effect of a multi-disciplinary program on anthropometric and biochemical parameters in obese and overweight elementary school girls: A randomized clinical trial.

BACKGROUND AND AIMS: Obesity and overweight in children are associated with an increased risk of several health issues. The present study aimed to assess the effects of a multi-disciplinary program (including nutrition education using a smartphone game, physical activity, and cognitive behavioral therapy [CBT]) on the management of obesity and overweight in elementary school girls. METHODS AND RESULTS: Sixty-two school girls above the 85th percentile of body mass index (BMI) for age were randomly assigned to two groups. During 10 weeks of study, the intervention group received a multi-disciplinary intervention, including nutrition education using a smartphone game, aerobic exercise, and CBT. The control group received usual traditional nutritional education. Biochemical and metabolic factors were assessed, including fasting blood sugar (FBS), lipid profile, serum leptin, and anthropometric measurements. The Dutch Eating Behavior Questionnaire (DEBQ) and metabolic equivalent test (MET) were also conducted. The intervention group showed more promising results in weight loss, waist circumference (WC), hip circumference (HC), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG), and FBS compared to the control group (P < 0.05). In addition, MET and DEBQ scores in all three sections of emotions, stimuli, and restriction were better in the intervention group than in the control group (P < 0.05). However, there was no significant difference between groups regarding the results of serum leptin and waist-to-hip ratio (WHR; p > 0.05). CONCLUSIONS: The results indicated that education through smartphone games could possibly affect performance in real life. In addition, the multi-disciplinary approach to childhood obesity might have better performance in most areas than the single-intervention approach in obesity management.

Assessment of educational intervention and Acupressure during labor on the mother's anxiety level and arterial oxygen pressure of the umbilical cord of infants (PO2). A randomized controlled clinical Trial.

BACKGROUND: Natural delivery is distressing, and the mother's anxiety in this condition can have negative impacts on the fetus, mother, and the delivery process. Hence, many women tend to use pharmacological or nonpharmacological methods for reduction of labor stress and anxiety. The aim was to assess the effect of supportive care and acupressure during labor on the mother's anxiety level and arterial oxygen pressure of the umbilical cord of infants. MATERIALS AND METHODS: This performed on 150 pregnant women were randomly assigned to two interventions and a control group in the delivery ward of the selected educational center of Shiraz University of Medical Sciences (Shoushtari Hospital) in Iran. Mothers' anxiety scores before (beginning of the active stage of labor) and after intervention (the end of the first stage of labor) were measured using Spielberger's questionnaire. Then, infants' cord blood samples for arterial blood gas and hematologic analyses were sent to the hospital's laboratory. After all, the data with SPSS version 16 and using Pearson's correlation coefficient, one-way ANOVA, were analyzed. RESULTS: The mean of anxiety score in the control group was 21.1% and in the supportive group and the acupressure group, respectively, decreased by 37.5% and 34.8%, respectively (P < 0.001). The mean of PO2 was also reported in the maternal supportive, acupressure, and control groups, 40.4 ± 8.8, 27.4 ± 2.8, and 18.1 ± 3.7, respectively. Additionally, a significant correlation was found between mothers' anxiety scores after the intervention and the mean of PO2 (P = 0.014). CONCLUSION: The supportive care and acupressure at BL32 acupoint reduced mothers' anxiety and consequently improved fetal oxygenation. Therefore, these methods are recommended to be used during labor for improving birth outcomes.

Efficacy of Aromatherapy for Night Crying in Infants with Infantile Colic: A Double-Blind Randomized Controlled Trial.

Background: Too much crying is a self-limiting problem and disappears within a few weeks. However, it can lead to maternal depression and parental stress. This study aimed to evaluate the effect of lavender oil inhalation on the duration of night crying within a week of intervention among infants with infantile colic. Methods: In this double-blind randomized clinical trial, the inclusion criteria for infants were being healthy, not taking any medications for colic, having an episode of crying two hours a day, and having a healthy mother. The intervention group received lavender oil inhalation and the control group received sweet almond oil inhalation for seven days. The data pertaining to the duration of crying were collected four times a day (morning, afternoon, evening, and night) via telephone contact. Mothers' mood scores were also assessed at the beginning of the study and on the seventh day of the intervention. Results: At first, the two groups were not different in terms of the duration of crying. After the intervention, however, a significant difference was observed in this regard on all seven days of the study (P < 0.001). Based on the results of the repeated measures analysis, the difference between the two groups was statistically significant (P < 0.001). Conclusions: The results showed that inhalation of lavender oil at low concentrations could reduce colic symptoms and improve maternal mood.

Developing a Model for Prediction of Serum 25-Hydroxyvitamin D Level: The Use of Linear Regression and Machine Learning Methods.

OBJECTIVE: Because vitamin D status affects many organs and tissues of the body, it is important to determine the factors affecting it. The purpose of this study was to develop a model for predicting the serum 25-hydroxyvitamin D [25(OH)D] level in healthy young adults. METHOD: This cross-sectional study was conducted on 201 healthy individuals aged 20 to 40 years old in Shiraz, Iran. Data regarding demographic characteristics, vitamin D intake through supplements, and sun exposure habits were gathered. Serum 25(OH)D concentration was also measured. Data were analyzed with R software using linear regression and different machine learning methods such as conditional tree, conditional forest and random forest. RESULTS: Based on the linear regression, male sex (p < 0.001), taking 50,000 IU vitamin D3 supplement monthly (p < 0.001), and lower waist circumference (p = 0.018) were identified as effective factors in increasing serum 25(OH)D levels. According to the conditional tree, taking 50,000 IU vitamin D3 supplement monthly (p < 0.001) and sex (p < 0.001) were two main factors in the classification of individuals in terms of serum 25(OH)D levels. Besides, conditional forest and random forest results showed that the most important variable was taking 50,000 IU vitamin D3 supplement monthly. CONCLUSIONS: Supplement use is the first and most important predictor of 25(OH)D levels and other factors, including sex and waist circumference, are ranked thereafter, and the importance of these factors is greater in those who do not take vitamin D3 supplements.

Comparison of Maternal-Infant Attachment in Cesarean Delivery Based on Robson Classification: A Cross-Sectional Study.

BACKGROUND: The Robson criteria allows for standardized comparisons of data and possible driving changes in Cesarean Section (C/S) rates and complications. The aimed to compare maternal-infant attachment in C/S based on Robson Classification. MATERIALS AND METHODS: This cross-sectional prospective study was conducted on 369 women who had undergone C/S in Hazrate Zeinab Peace Be Upon Him (PBUH), Hafez, and Shooshtari hospitals affiliated to Shiraz University of Medical Sciences, Iran from April 2018 to March 2019. The study data were collected using a demographic form, an obstetric form, and Avant Checklist (AC) at postpartum and pre-discharge stages. Each participant was placed in Robson classification and the attachment score was calculated in each Robson Classification, and a comparison was made among the 10 groups. The data were analyzed into the SPSS 16 software and using descriptive statistics and paired t test. RESULTS: The total mean (SD) score of attachment was 38.73 (18.65) at 1-7 h postpartum and 90.52 (23.79) at pre-discharge. The highest total mean (SD) score of attachment was observed in group 6 (86.78 (8.70) at postpartum and 118.67 (4.47) at pre-discharge). The lowest total mean (SD) score of attachment was observed in group 10 (12.79 (2.37) at 1-7 h postpartum and 45.44 (7.99) at pre-discharge). CONCLUSIONS: Obstetric characteristics in Robson Classification, parity, previous C/S, gestational age, onset of labor, fetal presentation, and number of fetuses were effective in clarifying information. The use of this system is necessary to determine the causes of increased C/S cases in low-income and middle-income countries.

Promotion of posttraumatic stress disorder following traumatic birth experiences and the influence of maternity religious Attitude: A correlational study.

BACKGROUND: Women who experience stillbirth and preterm delivery are likely to be associated with an increased risk of posttraumatic stress disorder (PTSD) compared to women with live births and dose religious attitude related to posttraumatic stress? The aim of the study was promotion PTSD following traumatic birth experiences and the influence of maternity religious Attitude. MATERIALSAND METHODS: A cross-sectional analytical study was conducted at selected hospitals of Shiraz University of Medical Sciences on 82 subjects in 2018. The instruments were demographic questionnaire, Religious Attitude questionnaire, and Mississippi PTSD Scale which were completed after delivery. Data were analyzed using SPSS software, version 22, using the Pearson correlation test. RESULTS: About 75% stillbirth group and 65% of the preterm delivery group had a high level of religious attitude. In the stillbirth group, 90% had high levels of PTSD and in the preterm delivery group, 90% had moderate stress, and 10% had high PTSD levels. The correlation between religious attitude and PTSD after stillbirth was 0.373 with a significance level of 0.018. Therefore, there was a significant positive relationship between religious attitude and PTSD. However, the relationship between religious attitude and PTSD after preterm delivery was not statistically significant (P = 0.158). CONCLUSION: PTSD was significantly higher in mothers with stillbirth and had a significant relationship with religious attitude. However, in mothers of preterm infants, the level of stress was moderate and did not have a significant relationship with religious attitude. The findings indicate the need of mothers for interventions to cope better with the physical and psychological problems of stillbirth and preterm delivery.

Effect of Maternal Pethidine on Breast Feeding Behavior of Infants in Cesarean Section by Spinal Anesthesia: A Randomized Controlled Trial.

BACKGROUND: Pain control methods after cesarean section may interfere with infant breast-feeding. The aim of this study was to evaluate the effect of pethidine on breast feeding of infants born via cesarean section with spinal anesthesia. METHODS: In this randomized double-blind clinical trial, we evaluated 116 infants born via cesarean section in Gerash Amiralmomenin hospital (Southern Iran) in 2017. The subjects were selected through purposive sampling and randomly by permuted block randomization and assigned to intervention and control groups. The test group received 100 mg of pethidine as intravenous infusion and the control group received only routine cares. Infants' breast feeding behavior in both groups was recorded within 48 hours of hospitalization, using the standard tool for rapid assessment of infant feeding behavior, which consists of 4 main components of breastfeeding, including readiness to feed, rooting, latching, and sucking with a score range of 0 to 3 for each component evaluated at 1, 6, 12, 24, 36, and 48 hours postnatally. Data were analyzed using independent t tests and chi-square test. RESULTS: The highest score of breast-feeding behavior pertained to sucking reflexes in the control group and the lowest score to breast feeding readiness in the pethidine group. Readiness for feeding in the control group (2.09±0.53) was significantly higher than the pethidine group (1.81±0.61) (95% CI: 0.0552, 0.5092 and P=0.015). Sucking reflex (95% CI: -0.1461, 0.2208 and P=0.687), latching (95% CI: -0.3012, 0.0345 and P=0.118) and rooting reflexes (95% CI: -0.1685, 0.2342 and P=0.747) were almost equal in the control group (2.54±0.49, 2.52±0.38, 2.5±0.48, respectively) and pethidine groups (2.51±0.43, 2.65±0.45, 2.46±0.53, respectively). The total score of feeding behavior in the control group (9.66±1.04) was higher than that of the pethidine group (9.44 ±.69) (95% CI: -0.2032, 0.6412 and P=0.306). There was no significant difference between the infants' feeding frequency (95% CI: -0.269, 1.930 and P=0.137) and duration of feeding (95% CI: -3.2067, 0.4597 and P=0.14). CONCLUSION: Evaluation of infants in the first 48 hours after birth showed that those babies whose mothers received pethidine were less willing to start breast-feeding. However, other components of breast-feeding behaviors were similar.

A multi-disciplinary approach to weight management of school-age girls: a study protocol.

INTRODUCTION: There is lack of data about the combination of multiple approaches to control being overweight and obesity in adolescents. This study aimed to evaluate the effect of a combination program including smart-phone nutrition education, physical activity, and cognitive behavioral therapy (CBT) programs in the management of obesity and overweight among elementary school girls in comparison with a traditional education method. MATERIAL AND METHODS: The primary outcome of this study is the assessment of changes in anthropometric data after 10 weeks. The secondary outcome is investigating the effect of treatment on biochemical data. Sixty-two elementary school girls aged 9-12 years with the body mass index (BMI) for age above 85th percentile will be chosen and randomly assigned to one of the two groups of control or intervention. During the 10 weeks of the intervention, smartphone games will be given to the children with some information at the beginning about the causes and complications of obesity, food sources of fiber and vitamins, and banned foods during the intervention period. Students in the intervention group will participate in an aerobics exercise for 45 minutes three times per week under the supervision of an experienced trainer and eight CBT Sessions which were designed for children by a clinical psychologist. Anthropometric measurements, including height, weight, waist circumference (WC), hip circumference and waist to hip ratio(WHR), and biochemical and metabolic lab data, including fasting blood sugar (FBS), total cholesterol, high density lipoproteins (HDL), low density lipoproteins (LDL), leptin and will be measured at the baseline and 10 weeks later at the end of intervention period . Also, both questionnaires of metabolic equivalent test (MET) and Dutch Eating Behavior Questionnaire (DEBQ) will be completed for each student at baseline and after 10 weeks. The students in the control group will receive traditional education in the form of lectures given by a nutritionist regarding weight management.
