RESUMO

BACKGROUND: There is a lack of scientific literature on the application of fear appeals theories to evaluate lung cancer risk perception among smokers. The aim of the present study is to apply the Extended Parallel Process Model (EPPM) to discover the perception of the smokers about their lifetime risk of developing lung cancer (perceived susceptibility), their perception of lung cancer survival (perceived severity), response efficacy, self-efficacy, and readiness to quit. METHODS: In this cross-sectional study, 215 eligible smokers (aged 45 years and over who have smoked at least 1 pack per day in the last 5 years) were recruited. The data collection tool was designed using validate self-report questionnaires and it was contained items on the perceived risk of a smoker contracting lung cancer and perceived lung cancer survival rate. It also had questions to measure the main constructs of the EPPM and Readiness to quit ("Low_Readiness", and "High_Readiness"). To test how the data support conceptual EPPM to data, Generalized Structural Equation Modeling (GSEM) was used. RESULTS: Findings showed a significant relationship between Perceived_Susceptibility and Perceived_Response Efficacy; (B = 1.16, P < 0.001); between Perceived_Susceptibility and Perceived_Self Efficacy, (B = -0.93, P < 0.001), Perceived_Severity, and Perceived_Response Efficacy (B = 1.07, P < 0.001). There was also a significant relationship between Perceived_Threat and Perceived_Response Efficacy; between Perceived_Threat and Perceived_Self Efficacy. The relationship between High_Readiness and Perceived_Self Efficacy, and between High_Readiness and Perceived_Severity also were significant. However, the relationships between High_Readiness and Perceived_Threat were not significant (P > 0.05). CONCLUSION: Perceived_threat and Perceived_efficacy were important for smokers with low readiness to quit, while Perceived_efficacy was most important for smokers with high readiness to quit. These findings could be used in promoting lung cancer awareness and designing smoking cessation programs based on smokers' stages of change.

RESUMO

(1) Background: The older adult population of society is exposed to multiple stressors daily, such as the loss of loved ones, dysfunctional mobility, financial dependence, and suffering from numerous chronic illnesses. The present study aimed to assess the psychometric properties of the Anxiety about Aging Scale among older adults in Iran. (2) Methods: A sample of 703 community-dwelling older adults was recruited and screened using a standardized tool. The mean age of participants was 69.4 ± 8.1 years. The majority of participants were male (59.2%), married (66.6%), and illiterate (79.7%). A 'forward-backward' translation method was used in developing the Iranian version of the AAS for assessing the psychometric properties among older adults. Confirmatory factor analysis (CFA) and the Rasch model were used for construct validity. (3) Results: Applying CFA indicated that the model's four original factors are the best solution, representing 55% of the total variance. The result of the CFA showed that this four-factor model had a good fit for the data. The findings were also confirmed by Rasch analysis. (4) Conclusions: The Persian version of the AAS is valid and reliable for measuring aging anxiety among Iranian older adults.

RESUMO

BACKGROUND: The aim of this study was to compare fear of childbirth, state and trait anxiety, and childbirth self-efficacy among primiparous and multiparous women in Ahvaz, southwest of Iran. METHODS: This cross-sectional study was conducted with 200 pregnant women (100 primiparous and 100 multiparous women) who had been admitted to the maternity ward of hospitals affiliated to Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran. The instruments used for data collection in this study included a demographic questionnaire, Delivery Fear Scale (DFS), Spielberger's State-Trait Anxiety Inventory (STAI), and Childbirth Self-Efficacy Inventory (CBSEI). The data were analyzed by chi-square test and independent t-test. Also, the univariate general linear model was used by adjusting for the socio-demographic and obstetric characteristics that were considered as possible confounding variables. RESULTS: The mean score of DFS in primiparous women was significantly higher than that of multiparous women. The mean of the overall score of childbirth self-efficacy of primiparous women was significantly lower than that of multiparous women. The mean score of the outcome expectancies and self-efficacy expectancies was significantly lower in primiparous women compared with multiparous women. There was no statistically significant difference between the two groups in terms of the mean score of STAI. After adjusting for possible confounding variables, the differences between the two groups in terms of fear of childbirth scores, overall childbirth self-efficacy score and self-efficacy expectancies remained significant. CONCLUSION: Given the high fear of childbirth and low childbirth self-efficacy in primiparous women compared to the multiparous women, appropriate interventions should be adopted by health care providers in order to reduce fear and improve childbirth self-efficacy in primiparous women.

RESUMO

BACKGROUND: Anxiety is one of the most prevalent mental health disorders among mothers during the postpartum period, which can lead to maternal and infant physical and psychological consequences. The Postpartum Specific Anxiety Scale (PSAS) predicts unique variance in postnatal outcomes over and above general anxiety tools. It has never been used in Iran and its validity and reliability have not been assessed either. Therefore, the present study aimed to translate and investigate the psychometric properties of the PSAS-IR. METHODS: 510 women, from six weeks to six months postpartum, were selected through random sampling in 2020. After forward and back-translation, the face validity, content validity, and construct validity of PSAS (through confirmatory factor analysis) were examined. The reliability of the scale was assessed using both internal consistency (Cronbach's alpha) and test-retest stability methods. RESULTS: CVI and CVR values of the PSAS tool were 0.89 and 0.88, respectively. The good fit indices confirmed the validity of four-factor structure. Cronbach's alpha coefficient and Intra Correlation Coefficient (ICC) equaled 0.93 and 0.92, respectively. CONCLUSION: The Persian version of PSAS is a valid and reliable four-factor scale, it will improve the measurement of postpartum anxiety in an Iranian setting. This will improve the measurement of postpartum anxiety in an Iranian setting.

RESUMO

Particulate air pollutants are known contributors to global cardiorespiratory mortality through several pathways. We examined the effects of varied exposure to PM2.5 and trace metals on biological markers of airway inflammation, oxidative stress, and hemodynamic function of young individuals living in two different exposure settings. We enrolled and followed a panel of 97 healthy nonsmoking participants aged 15-18 years living in a highly polluted metropolitan city of Tabriz (TBZ) and a much less polluted semi-urban town of Hadishahr (HDS). For five consecutive months, the subjects were examined by a physician, and fractional exhaled nitric oxide levels (FENO) were measured. Samples of exhaled breath condensation (EBC) were obtained for measuring interleukin 6 (IL-6), tumor necrosis factor α (TNF-α), and total nitric oxide (NOx). We measured daily outdoor PM2.5 mass concentration in a fixed station in each location for all this period. The PM-metal content was analyzed by ICP-MS. The linear mixed-effects regression models were applied for data analysis. The averages of PM2.5 mass and total metals in TBZ were nearly two and four times higher than in HDS, respectively. In TBZ, an increased IQR of PM2.5 mass during 0-5 days was -correlated with a significant rise in diastolic blood pressure, heart rate, TNF-α, FENO, and NOx and reduction of IL-6. Moreover, exposure to low PM2.5 concentration is significantly -correlated with an elevation in diastolic blood pressure in HDS. We also observed that exposure to metal constituents in the highly polluted region is correlated with increased TNF-α and IL-6 with 131.80% (95% CI: 56.01, 244.39) and 47.51% (95% CI: 33.01, 62.05) per IQR of Hg, respectively. This study suggests that exposure to ambient PM2.5 and their metal contents in highly polluted areas may incite significant changes in airway inflammation, oxidative stress, and hemodynamic parameters in healthy subjects.

RESUMO

BACKGROUND: Women's satisfaction with childbirth experience is considered as one of the quality indicators of the maternity services across the world. However, there is no guideline for improving the experience of childbirth in Iran that is suitable for women with different cultural, economic, and social statuses. The aim of this study is to make recommendations for practice and propose a clinical guideline for improving the experience of women with vaginal births. METHODS/DESIGN: The study design was a mixed method study with a sequential explanatory approach consisting of three phases. The first phase of the study was a cross-sectional study to identify the predictors of traumatic vaginal childbirth experience among 800 primiparous women from Tabriz health centers who had vaginal birth. Data collection tools in this phase were Childbirth Experience Questionnaire (CEQ) and Support and Control in Birth (SCIB). Both tools were validated for Farsi language. The second phase was a qualitative study with 17 in-depth individual interviews among women who took part in the first phase to better understand their reasons that influenced their childbirth experience either positively or negatively. The third phase of the study was to develop recommendations for a proposed clinical guideline through a Delphi study where maternal health experts were selected and invited to take part in the panel. They first rated the proposed recommendations individually and provided written responses on their own agreement or disagreement with each statement in terms of its impact on childbirth experience, feasibility, acceptability, and cost-effectiveness. After three confirmation rounds, the final conscience was reached by the panel members. RESULTS: The results of the quantitative phase showed that the probability of negative experience of childbirth was increased when physical exercise was not implemented during pregnancy, lacking pain relief options, having fear of childbirth, lacking skin to skin contact with the newborn and being unable to initiate breastfeeding in the first hour after birth (P < 0.05). The analysis of qualitative data revealed 13 major theme categories which were related to women's sense of internal control, external control and support. In the third phase of the study, culturally appropriate recommendations were made and an evidence-based clinical guideline was proposed. The proposed guideline was based on the combination of the quantitative and qualitative phases, a review of the literature, and the opinions of Iranian experts using the Delphi technique. CONCLUSION: Given the high prevalence of negative childbirth experience among Iranian primiparous women, the present study may be of great interest for managers, leaders, policymakers, and care providers to improve the quality of the maternity services. However, further studies are required to translate the recommendations into practice and identify enablers and barriers during the implementation of the proposed guideline. To adopt the recommendations at national level, there is a need to further studies to assess the effectiveness of the proposed guideline within different communities across the region and the country.

RESUMO

BACKGROUND: Education by smartphone-based software is a new method among the world's educational practices. Due to the lack of studies on the effect of this education on promoting knowledge and self-care behaviors of students' reproductive health this study aimed to determine the effect of smartphone-based software education on knowledge and self-care behaviors in the field of reproductive health. MATERIALS AND METHODS: This RCT with 164 married female students (82 in each group) conducted from October 2019 to January 2020, in Tabriz University and Tabriz medical University. Participants were randomly allocated to two groups of educational intervention and control. Smartphone-based software education designed in four areas of reproductive health. Intervention group was trained for 4 weeks. The score of knowledge and self-care behaviors of participants in both groups were compared at baseline and 8 weeks after intervention. Data were analyzed by SPSS-23 software using Chi-square, independent t-tests, and analysis of covariance tests. RESULTS: Eight weeks after the intervention, a significant increase was observed in the mean (standard deviation [SD]) score of overall knowledge for reproductive health and all its subdomains (P < 0.001), as well as in in the mean (SD) self-care score of reproductive health and all subdomains (P < 0.05), except for the family planning in the education group compared to the control group. CONCLUSION: The findings indicate a significant effect of smartphone-based software on increasing students' knowledge and self-care in all areas of reproductive health except for family planning subdomain of self-care.

RESUMO

PURPOSE: The slow coronary flow (SCF) was identified as delayed opacification of epicardial coronary arteries in the absence of stenotic lesion. Metabolic syndrome (MetS), oxidative stress, and inflammation may be possible known insulting factors for the pathogenesis of SCF. This investigation aimed to assess the relationship between some inflammatory markers, oxidative stress parameters and MetS components with SCF phenomenon. METHODS: A total of 35 patients with SCF and 35 subjects with normal coronary flow (NCF) were included in the study. We assessed some inflammatory markers (IL-1ß, IL-18, TNF-α, and NF-κB mRNA expression in peripheral blood mononuclear cells (PBMCs)). Moreover, blood samples of the participants were tested for total antioxidant capacity (TAC), glutathione peroxidase (GPX) and nitric oxide (NO) levels using enzyme-linked immunosorbent assay (ELISA). Diagnosis of MetS was based on the National Cholesterol Education Program's Adult Treatment Panel III report (ATPIII) criteria, 2005. Diagnostic criteria for coronary flow rates of all subjects were documented by thrombolysis in myocardial infarction (TIMI) frame count method. RESULTS: SCF patients had significantly higher prevalence of MetS (46%, p = 0.048).We found that the level of TAC was significantly higher in the NCF group (p = 0.006). Furthermore, the NO concentration was significantly lower in SCF groups (p = 0.001). A significant incremental difference was detected in IL-1ß (fold change 2.82 ± 0.31, p < 0.05) and NF-κB (fold change 4.62 ± 0.32, p < 0.05) mRNA expression in the SCF group when compared with its level in the NCF group. Furthermore, according to logistic regression analysis, there were significant associations between IL-1ß, NF-κB expression levels and the incidence of SCF (p < 0.05). CONCLUSION: Based on the findings of this study, the pathogenesis of the SCF phenomenon may be closely associated with metabolic syndrome and inflammation. The NF-κB/IL-1ß/nitric oxide & MetS signaling pathway might be considered as potential therapeutic targets in the management of SCF patients but further researches is required to guarantee these findings.

RESUMO

BACKGROUND: Socioeconomic disparities in health and healthcare are global issues that affect both adults as well as children. Children with exceptional healthcare needs, especially those with developmental impairments, including Autism Spectrum Disorders (ASD), encounter major disparities in access to and quality of health services. However, disparities in the population of children are rarely studied. The main aim of this paper is to study the socioeconomic disparities in children with ASD by examining the association between their Social Determinants of Health (SDH) status and access to and the quality of services. METHODS: This is a cross-sectional study on 202 children with ASD conducted in 2019 in two provinces including Ardabil and East-Azerbaijan, in the North-West of Iran. A structured, valid questionnaire was used to collect data on demographic, SDH status, quality of services, and access to services in a population of children with ASD aged 2-16-year-old. Around 77% participants were male and the mean age of children was 2 years and 6 months. Structural Equation Modeling (SEM) were used to assess the relationship. RESULTS: Based on the results of this study, the overall mean scores of the quality of services, access to services, and SDH status were 61.23 (30.01), 65.91 (21.89), and 29.50 (22.32) out of 100, respectively. All the associations between the quality and access dimensions and quality (B: 0.464-0.704) and access (B: 0.265-0.726) scales were statistically significant (P < 0.001). By adjusting to covariates, the access was also significantly related to service quality (P = 0.004). Finally, the associations between SDH score with service quality (P = 0.039) and access (P < 0.001) were positively significant. CONCLUSIONS: There are socioeconomic disparities in the quality of and access to services among children with ASD, who use ASD services, in the North-West of Iran. We recommend health/medical centers, where children are diagnosed with ASD, conducting SDH screening and providing families of low-SDH status with specific information about the quality of and access to services for children with ASD. Additionally, medical universities must have a plan to routinely monitor the quality of and access to services provided for the children with low SDH.

RESUMO

Recent events regarding the COVID-19 pandemic have demonstrated the importance of healthcare workers around the world and the stressful working conditions that are often associated with their profession. The severity of stress can be influenced by a number of factors such as age, seniority gender, family status, and position in the wards. Thus, it is important to monitor signs of stress and other psychiatric symptoms in order to understand the mediating factors and guide appropriate interventions. Here, we describe a cross-sectional study of 17,414 nurses from 31 Iranian cities carried out from 2011 to 2015, using a 22-item tool of work stressors. The tool examined interactive, managerial, and situational domains and the main objective was to identify the main background variables associated with the stress of nurses in critical care settings.

RESUMO

BACKGROUND: The aim of the present study was to evaluate the psychometric properties of the Persian version of delivery fear scale (DFS) among Iranian women population. METHODS: This is a methodological study that was conducted to evaluate the psychometric properties of DFS. Convenience sampling was used to select 200 pregnant women from the maternity ward of Razi Hospital in Ahvaz, Iran. In the first step, the scale was translated into Persian using backward-forward translation method. Afterwards, the following types of validity were examined: face validity based on impact score, construct validity based on confirmatory factor analysis (CFA), and concurrent validity. The Pearson correlation test was used to determine the correlation of DFS with pregnancy-related anxiety questionnaire (PRAQ), Childbirth Attitude Questionnaire (CAQ), Spielberger's state-trait anxiety inventory (STAI), and the short form of Lowe's childbirth self-efficacy inventory. Reliability of DFS was assessed by determining internal consistency (Cronbach's alpha) and split-half method. RESULTS: CFA had satisfactory validity considering x2/df < 5 and the RMSEA < 0.08. /the obtained Cronbach's alpha coefficient was 0.77. The split-half coefficient of the questionnaire was 0.83, indicating an acceptable reliability for the questionnaire. The results showed that DFS had a direct significant correlation with the CAQ (r = 0.72), PRAQ (r = 0.74), STAI-Y1 (r = 0.71) and STAI-Y1 (r = 0.63) and a reverse significant correlation with subscales of the short form of Lowe's childbirth self-efficacy inventory including outcome expectancy (r= -0.75) and self-efficacy expectancy (r= -0.76). CONCLUSIONS: The findings of the present study confirm the validity and reliability of the Persian version of DFS as an instrument for measuring fear of childbirth (FOC) in Iranian women population.

RESUMO

OBJECTIVES: After heart disease, brain stroke (BS) is the second most common cause of death worldwide, underscoring the importance of understanding preventable and treatable risk factors for the outcomes of BS. This study aimed to model the survival of patients with BS in the presence of competing risks. METHODS: This longitudinal study was conducted on 332 patients with a definitive diagnosis of BS. Demographic characteristics and risk factors were collected by a validated checklist. Patients' mortality status was investigated by telephone follow-up to identify deaths that may be have been caused by stroke or other factors (heart disease, diabetes, high cholesterol, etc.). Data were analyzed by the Lunn-McNeil approach at alpha=0.1. RESULTS: Older age at diagnosis (59-68 years: adjusted hazard ratio [aHR], 2.19; 90% confidence interval [CI], 1.38 to 3.48; 69-75 years: aHR, 5.04; 90% CI, 3.25 to 7.80; ≥76 years: aHR, 5.30; 90% CI, 3.40 to 8.44), having heart disease (aHR, 1.65; 90% CI, 1.23 to 2.23), oral contraceptive pill use (women only) (aHR, 0.44; 90% CI, 0.24 to 0.78) and ischemic stroke (aHR, 0.52; 90% CI, 0.36 to 0.74) were directly related to death from BS. Older age at diagnosis (59-68 years: aHR, 21.42; 90% CI, 3.52 to 130.39; 75-69 years: aHR, 16.48; 90% CI, 2.75 to 98.69; ≥76 years: aHR, 26.03; 90% CI, 4.06 to 166.93) and rural residence (aHR, 2.30; 90% CI, 1.15 to 4.60) were directly related to death from other causes. Significant risk factors were found for both causes of death. CONCLUSIONS: BS-specific and non-BS-specific mortality had different risk factors. These findings could be utilized to prescribe optimal and specific treatment.

RESUMO

BACKGROUND AND AIMS: Available evidence substantiates a strong association between metabolic syndrome and elevated oxidative stress. This study was aimed to assess the effects of probiotic yogurt containing Lactobacillus acidophilus La5 and Bifidobacterium lactis Bb12 on the oxidative stress biomarkers in patients with metabolic syndrome. Furthermore, the association between uric acid levels and insulin resistance indexes was assessed. METHODS: An 8-week randomized, double-blind, placebo-controlled, parallel study was designed. Forty-four patients, 22 males and 22 females aged 20-65 years, were assigned into two groups. Treatment (n = 22) and control (n = 22) groups consumed 300 g/d of probiotic and regular yogurt, respectively. The serum concentration of uric acid, oxidized Low-Density Lipoprotein (oxLDL), Malondialdehyde (MDA) and Total Antioxidant Capacity (TAC) were measured at the beginning and the end of the trial. This study was recorded at http://www.irct.ir (code: IRCT201608213140N17). RESULTS: Probiotic yogurt consumption resulted in a significant decrease in the level of serum uric acid and a significant increase in the level of TAC (p < 0.05). A positive significant association between uric acid with insulin concentration and the homeostasis model assessment of insulin resistance (HOMA-IR) and an inverse significant relationship with insulin sensitivity (Quicki) were also found (p < 0.05). CONCLUSION: Probiotic yogurt consumption through improvement in insulin sensitivity may exert positive effects on the oxidative stress and uric acid levels. However, further studies are needed to make concise conclusions.

RESUMO

PURPOSE: The present study was performed to develop the Persian version of food craving inventory (FCI) (FCI-P) and to assess food craving in Iranian adult population. In addition, individual differences, including sex and body mass index (BMI) in food craving were assessed. METHODS: Eight hundred and twenty subjects who participated in the same study Hill (Proc Nutr Soc 66: 277-285, 2007) were studied (540 women and 280 men). The FCI-P, International Physical Activity Questionnaire (IPAQ), Three-Factor Eating Questionnaire (TFEQ), and a questionnaire pertaining to demographic characteristics were completed for all participants. RESULTS: Good content, construct, and convergent validity was observed for the FCI-P. A good reliability was found for both aggregate scores of the FCI-P and scores of its five factors. Exploratory factor analysis showed a five-factor model including "sweets," "high-fat foods," "fast food fats," "carbohydrates/starches" and "high-fat meats". These five factors accounted for 47.31% of the total variance. The scores of "uncontrolled eating" and "emotional eating" of the TFEQ were significantly correlated with the scores of the FCI-P factors and its total score. A significant correlation was found between BMI and the FCI-P score (r = 0.199). Significant differences were observed in the mean age and physical activity score among normal weight, overweight, and obese participants. Normal weight and overweight groups were more active than obese group. Obese participants had higher FCI-P score (P < 0.001) than the normal and overweight groups. FCI-P score was significantly higher in women than men. CONCLUSIONS: FCI-P can be used as a valid and reliable measure to assess food craving in Iranian populations. Obese individuals experienced food craving more than normal weight subjects. Similarly, women may experience food craving more than men. LEVEL OF EVIDENCE: Level V, cross sectional study.

RESUMO

BACKGROUND: To investigate the effects of probiotics on glucose metabolism and body mass index (BMI), and compare the efficacy of probiotic food with the probiotic supplement in patients with type 2 diabetes mellitus using a meta-analysis of randomized, controlled trials. METHODS: Online databases Embase, Web of Science, and PubMed were searched until November 2019 to identify eligible articles. Fourteen trials were included. RESULTS: Probiotic consumption reduced fasting plasma glucose (FPG) (SMD=-0.38, 95% CI: -0.76 to 0.01), glycosylated hemoglobin (HbA1c) (SMD=-0.64, 95% CI: -0.91 to -0.38), fasting insulin concentration (SMD=-0.48, 95% CI, -0.81 to -0.15), HOMA-IR (SMD=-1.01, 95% CI, -1.51 to -0.52), and BMI (SMD=-0.02, 95%CI, -0.17 to 0.13) in intervention groups compared with control groups. Subgroup analysis was conducted to trials with probiotic foods and probiotic supplements. Both of probiotic foods (SMD: -0.65, 95% CI: -1.04 to -0.26; SMD: -1.17, 95% CI: -2.14 to -0.20, respectively) and supplements (SMD: -0.64, 95% CI: -1.01 to -0.27; SMD: -0.98, 95% CI: -1.55 to -0.40, respectively) made significant reduction in HbA1c and HOMA.IR. Meta-analysis of trials with probiotic foods found non-significant changes in FBG and fasting insulin concentration (SMD: 0.11, 95% CI: -0.52 to 0.75; SMD: -0.14, 95% CI: -0.48 to 0.20, respectively); however the changes in trials with probiotic supplements were significant (SMD: -0.73, 95% CI: -1.22 to -0.23; SMD: -0.57, 95% CI: -0.97 to -0.17, respectively). Probiotic foods cause a non-significant raise in BMI (SMD: 0.23, 95% CI: -0.03 to 0.49); however, meta-analysis of trials with probiotic supplements found a non-significant reduction in BMI (SMD: -0.13, 95% CI: -0.31 to 0.04). CONCLUSION: The present meta-analysis suggests that consuming probiotics could improve glucose metabolism and affect body weight, with a potentially greater effect when probiotics are used as supplements.

RESUMO

It has been suggested that abdominal obesity might be a better cardiovascular diseases (CVDs) discriminator than overall obesity. The most appropriate obesity measures for estimating CVD events in Kurdish populations have not been well-recognized. The objective of the present study was, therefore, to determine the cutoff points of BMI, waist circumference (WC), waist-to-hip ratio (WHR), and waist to height ratio (WHtR) as the diagnostic cut-offs to discriminate the prevalent cardiovascular diseases. The data collected from Ravansar Non-Communicable Disease (RaNCD) cohort, the first Kurdish population-based study, was analyzed. The information related to BMI, WC, WHR and WHtR of 10,065 adult participants in the age range of 35-65 was analyzed in this study. Receiver operating characteristic (ROC) analyses were conducted to evaluate the optimum cut-off values and to predict the incidence of cardiac events. The results showed that WHtR had the largest areas under the ROC curve for cardiac events in both male and female participants, and this was followed by WHR, WC, and BMI. The optimal cut-off values for determining the cardiac events in the Kurdish population were BMI = 27.02 kg/m2 for men and BMI = 27.60 kg/m2 for women, WC = 96.05 cm in men and 99.5 cm for women, WHRs = 0.96 in both sexes, and WHtR = 0.56 for men and 0.65 for women. The current study, therefore, showed that WHtR might serve as a better index of prevalent cardiac event than BMI, WHR and WC.

RESUMO

BACKGROUND: Given the importance of the childbirth experience, its effects on women's life and society, and the need for its assessment by accurate instruments, this study aimed to determine the psychometric properties of the Questionnaire for Assessing the Childbirth Experience (QACE) in an Iranian women population. METHODS: The validity of the Farsi edition of the questionnaire was assessed using the opinions of eight experts. Its construct validity was assessed by studying 530 mothers, at 1-4-month postpartum, who delivered in health centers of Tabriz, Iran. The exploratory factor analysis (EFA) was performed to identify its factors. Then, the confirmatory factor analysis (CFA) was performed for the structural assessment of the extracted factors. Spearman's correlation coefficient was used to investigate the correlation between factors. Cronbach's alpha and intraclass correlation coefficient (ICC) were used to obtain the internal consistency and test-retest reliability. RESULTS: In total, four factors were extracted from the EFA: "relationship with staff" (4 questions), "first moments with the newborn" (3 questions), "feelings at one-month postpartum" (3 questions), and "emotional status" (3 questions). According to the CFA, the model achieved desired fit level (RMSEA < 0.08, GFI, CFI, IFI > 0.90, and x2/df < 5.0). Cronbach's alpha (0.77-0.82) and intraclass correlation coefficient index (0.83-0.98) were desirable for all factors. CONCLUSION: The short edition of the QACE, as a standard tool, can be used by future studies to measure the experience of Iranian women.

RESUMO

Background: Poor mental health is common among adolescents. Given the increasing burden of poor mental health among adolescents in developing countries, it seems necessary to identify the effective interventions. The main purpose of this study was to investigate the effects of a school-based mental health promotion program (SMHPP) on mental health parameters among female adolescents in Tabriz, Iran. Method: In this experimental study, a random sample of female high-school students of grade nine was recruited. The subjects were then randomly allocated to intervention (n = 145) and control (n = 139) groups. The three-stage SMHPP was designed based on the shortages and unmet needs of the students as reported in the pretest stage. All subjects in the intervention group were provided with a stress management skill training program of six sessions using McNamara Model. Coincided with making environmental changes, a joyful intervention program was carried out. After 2 months, post-test data were collected. Results: A total of 284 students completed their participation in the study. The groups did not differ in none of socio-demographic characteristics and mental health parameters, at baseline. The number of subjects reporting medium-level of happiness was increased by 32.6% among intervention group. Moreover, upon sign test and pre-post comparison, the group-wise distribution changed between the intervention and control groups for the parameters of life satisfaction (p ≤ 0.001) and psychological well-being (p ≤ 0.01). Conclusion: The implementation of SMHPP as a low-cost, needs-based and multifaceted program, showed promise in promoting adolescents' mental health, particularly in the parameters of happiness, life satisfaction and psychological well-being. This was an important evidence for the development and implementation of interventions and policies in the field of mental health promotion among adolescents. Our work provided means for reducing burden of poor mental health among adolescents in a non-western cultural context. Further larger studies are required to evaluate the effectiveness of such school-based mental health promotion interventions in students.

RESUMO

BACKGROUND AND AIM: The association with obesity of a common variant near the melanocortin-4 receptor (MC4R) gene (rs17782313) has been indicated in various studies. Adherence to dietary quality indices also have shown to have potential favorable effects on obesity-related health outcomes. However, no study has examined the interaction between rs17782313 and the Dietary Approach to Stop Hypertension (DASH) score and the Mediterranean Dietary Score (MDS) on cardio-metabolic risk factors and hypothalamic hormones. Therefore, the purpose of the current study was to examine whether adherence to these dietary quality indices modifies the association of the MC4R rs17782313 polymorphism with cardio-metabolic risk factors and hypothalamic hormones among obese adults. METHOD: Two hundred eighty-eight healthy obese adults were recruited in this cross-sectional study. Diet quality indices, including DASH score and MDS, were calculated from a validated 147-item food frequency questionnaire (FFQ). MC4R s17782313 genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). An ANCOVA multivariate interaction model was used to assess the gene-diet interaction. RESULTS: Significant interactions were detected between DASH score and MC4R rs17782313 genotypes on systolic blood pressure (SBP), atherogenic index of plasma (AIP), and serum glucose and triglyceride (TG) among the female group (pInteraction < 0.05). In the male group, there were gene-DASH and gene-MDS interactions in relation to serum glucose concentration and plasma α-melanocyte stimulating hormone (MSH) levels, but these were found only in multi-adjusted interaction models (pInteraction < 0.05). In addition, there was a significant interaction between MC4R rs17782313 polymorphism and DASH score on plasma agouti-related peptide (AgRP) concentrations in the female group in a multivariate interaction model (pInteraction < 0.05). An inverse association between DASH score and chance of having the CC genotype in a multivariate-adjusted model among women was also revealed. CONCLUSION: MC4R rs17782313 interacts with healthy dietary pattern (DASH score and MDS) to influence cardio-metabolic risk factors and hypothalamic hormones in obese individuals. Prospective cohort studies are needed to further assess these findings.
