No full textOnline positive-oriented counseling, taking vitamin D3 tablet, online lifestyle modification training on premenstrual syndrome: a 3-armed randomized clinical trial
No full textAbstract Lack of absolute treatment for premenstrual syndrome (PMS), its cyclic nature, considerable prevalence (70–90%), and its mental and physical burden imply necessity of effectiveness comparison of various treatments. Although antidepressant and hormonal drugs are well-known medications for PMS, in affected women who can’t tolerate, or don’t have compatibility or compliance with these drugs, other effective treatments have always been important concern. This study aimed to compare effectiveness of online positive-oriented counseling, taking vitamin D3 tablet, and online lifestyle modification training on alleviating PMS. 3-armed parallel randomized clinical trial was performed on 84 20–40-year-old eligible women with PMS. 84 women were randomly ( www.random.org/sequenc ) allocated into three groups, but data of 77 women (1, n = 25) online positive-oriented counseling group (6 sessions), (2, n = 27) vitamin D3 tablet group (one vitamin D3 tablet weekly for 6 weeks), and (3, n = 25) online lifestyle training group (6 sessions) were analyzed. Vitamin D3 was measured at baseline, week6 and fallow up week10. Primary outcome variable PMS was measured with Premenstrual Symptoms Screening Tool (PSST) at baseline, week 6, and follow-up week 10. Primary outcome satisfaction with intervention method was measured using satisfaction scale at week 6 and follow-up week 10. ANOVA, Repeated Measures, and Paired samples t-test were used for statistical analysis. There was no statistically significant difference in PMS at baseline between three groups respectively (33 ± 5.8, 34.1 ± 7.1, & 35.2 ± 6.4, P = 0.500). However, at follow-up week 10, there was statistically significant difference between three groups (22.3 ± 4.3, 25.4 ± 6.5, & 31.8 ± 6.5; P < 0.001), with greatest improvement in online positive-oriented counseling group (P < 0.001). Satisfaction differed significantly among three groups at week 6 (51 ± 6.8, 46.4 ± 12, & 42.3 ± 6.3, P = 0.001) and follow-up week 10 (55.7 ± 11.6, 51.4 ± 12; & 43 ± 3.3, P < 0.001), with most satisfaction in positive-oriented counseling group (P < 0.001). All three interventions alleviated PMS, but online positive-oriented counseling was more effective and satisfying. Superiority of positive-oriented counseling implies mechanism of adaptation, better relationships, forgiveness, self-mood-regulation, and feasibility of its skills that could be continued individually by women after counseling completion. It is recommended health providers, health policymakers and managers support use of these interventions in treatment program and clinical guidelines.

Nutritional intake status of carpet weavers in Yazd-1390
No full textBackground: Proper nutrition can affect the health status of next generation. Nutritional status of women workers is so important. This study has been done to determine energy, macro and micronutrient intakes and to compare with dietary standards.
Methods: This descriptive cross sectional study has been done on 300 carpet weaver in Yazd. After measuring height and weight, dietary intake was determined using 3 day 24 h dietary recall questionnaire and analyzed by Nutritionist 4 software. Descriptive analysis and t-test were used by SPSS software.
Results: After omitting over and under reporting, data of 170 workers were analyzed. Mean of body mass index was 23.39±3.84 Kg/m2. Mean of energy intake was 2536.4±473.7 Kcal/d while 55.65, 10.86, and 33.48 percents of energy have been supplied by carbohydrate, protein and fat, respectively. Dietary intakes of vitamin A and C were significantly lower than Dietary Reference Intakes (DRI). Energy excess was seen in 91.7 percent of women and 31.8 percent of them were obese or overweight.
Conclusion: according to this study, micronutrient deficiencies are the issue in women in spite of energy excess
The nutritional content required to design an educational application for infertile women
No full textAbstract Background Infertility has been considered as a critical health problem for couples and society. Given the worldwide exponential rise of infertility, mobile phone-based applications are drastic ways to deliver nutrition educational content to women with infertility. The present study aimed to prepare the required educational content for designing a mobile phone-based nutrition educational application for women with infertility. Methods Educational contents were initially determined based on the literature review and library studies. As a result, a researcher-made questionnaire was designed containing 28 items in six dimensions. To ensure about the questionnaire’s validity, a panel of experts (15 nutritionists and 5 infertility specialists) was asked to review the items, make revisions (if necessary), and confirm the final contents. The questionnaire reliability was also corroborated using the KR-20 coefficient (0.89). Results While the amount of consumed calories per meal and between meals were not significantly effective on fertility, factors such as main definitions, disease and treatment instructions, personal activities and habits, and menstruation were deemed necessary by the respondents. Participants also suggested adding sections entailing introductions to different types of diets, users' suggestions and opinions, and of the address and contact information of senior nutrition centers to the questionnaire. Conclusions Followed by obtaining the required valid and reliable contents, a mobile phone- based nutrition education application can be designed to improve the patients' knowledge and facilitate their treatment process
Relation between road accidents and sleep quality of heavy vehicle drivers in Yazd
No full textAims: The aim of this study was to study the sleep quality of truck and trailer drivers in Yazd and its relation with traffic accidents and associated expenses.
Materials and Methods: This cross-sectional descriptive study included nonrandom simple method including 200 truck and trailer drivers. A two-sectional questionnaire was used: the first section included the standard Pittsburgh sleep quality questionnaire, while the second section included demographic characteristics of the subjects. Data were analyzed using descriptive statistical method and T-test analysis through SPSS 17 software.
Findings: The mean daily sleep period of the subjects under study was 6.46 ± 1.8 h and the mean of sleep quality score was 7.22 ± 2.72 h. Of the total, 75.5% had a sleep quality score greater than 5 that depicts the low quality of sleep in them. 29.5% had suffered from accidents in the last decade and 28% of those were due to sleepiness. The distribution of the sleep quality score on basis of sleep duration and falling sleep time was meaningful. The distribution of history of cigarettes smoking, narcotics abuse, and use of sedatives on basis of sleep quality score was also significant (P < 0.05).
Conclusion: The results showed that 75.5% of the truck and trailer drivers had sleep quality disorders and accidents resulting in injuries. Sleep quality in drivers who had precedence of accidents was lower than the drivers without any accidents so sleepiness can be one of the main causes of accidents among the professional drivers in Iran
Effect of dietary approaches to stop hypertension and curcumin co-administration on glycemic parameters in polycystic ovary syndrome: An RCT
No full textBackground: Polycystic ovary syndrome (PCOS) is an endocrine disorder that can lead to major reproductive and metabolic complications. Management of glycemic parameters is an important step to improve the symptoms of PCOS.
Objective: This study aims to evaluate the effects of the dietary approaches to stop hypertension (DASH) diet and curcumin (Cur) co-administration on glycemic parameters in normal weight and overweight/obese women with PCOS undergoing in vitro fertilization.
Materials and Methods: In this double-blind randomized clinical study, 104 infertile women with PCOS were divided into 4 intervention groups considering treatment conditions and body mass index. They received 500 mg twice daily of Cur or placebo (Pls) along with DASH or a standard diet (St) based on macronutrient composition (52% carbohydrate, 18% protein, and 30% fat) for 12 wk, (DASH + Cur, DASH + Pls, St + Cur, St + Pls). The effect of these interventions on fasting blood sugar and insulin levels, insulin resistance (IR), and insulin sensitivity were determined.
Results: Participants adhered to the intervention protocol (> 80%). Insulin levels in the supplement intervention (Cur + diet) decreased significantly in the crude model. They remained significant even after adjusting for confounding variables in adjusted models (body mass index classification, energy difference, age, and physical activity levels at the baseline) (ß = -45.3, 95% CI [-73.23, -17.46], p = 0.002). Homeostasis model assessment of IR decreased significantly in the supplement intervention even after controlling for confounding factors in adjusted models. Changes in fasting blood sugar and insulin sensitivity were not significant in either the crude or adjusted models.
Conclusion: The study results show that adding Cur to the diet can positively reduce insulin levels, improve IR, and lead to faster recovery of hyperinsulinemia. Cur supplementation with a healthy diet has synergistic beneficial effects on glycemic parameters. Larger clinical trials with longer durations are needed to confirm these results.

Effect of ginger powder supplementation on nitric oxide and C-reactive protein in elderly knee osteoarthritis patients: A 12-week double-blind randomized placebo-controlled clinical trial
No full textAbstractThere is limited evidence that ginger (生薑 shēng jiāng) powder consumption can relieve pain and inflammation because of its special phytochemical properties. This study is aimed at investigating the effect of ginger powder supplementation on some inflammatory markers in patients suffering from knee osteoarthritis. This is a double-blind randomized placebo-controlled clinical trial with a follow-up period of 3 months that was conducted on 120 outpatients with moderately painful knee osteoarthritis. Patients were randomly divided up into two groups: ginger group (GG) or placebo group (PG). Both groups received two identical capsules on a daily basis for 3 months. Each ginger capsule contained 500 mg of ginger powder; the placebo capsules had 500 mg of starch in them. Serum samples were collected prior to and after the intervention and were stored at −70 °C until the end of the study. Serum concentration of nitric oxide (NO) and hs-C reactive protein (hs-CRP) were measured using enzyme-linked immunosorbent assay kits. There was no significant difference between the two groups in terms of inflammatory markers (i.e., NO and hs-CRP) prior to the intervention. However, after 3 months of supplementation, serum concentration of NO and hs-CRP decreased in the GG. After 12 weeks, the concentration of these markers declined more in the GG than in the PG. Ginger powder supplementation at a dose of 1 g/d can reduce inflammatory markers in patients with knee osteoarthritis, and it thus can be recommended as a suitable supplement for these patients
The Effect of Vitamin D Supplementation on the Androgenic Profile in Patients with Polycystic Ovary Syndrome: A Systematic Review and Meta-Analysis of Clinical Trials
No full textIt is suggested that vitamin D status is associated with androgenic profile in women with polycystic ovarian syndrome (PCOS). Although several clinical trials are known in this regard, the results were inconsistent. Therefore, this study was aimed to conduct a systematic review and meta-analysis of published clinical trials to elucidate the possible effect of vitamin D supplementation on the androgen levels in adult females with PCOS. PubMed, SCOPUS, and Google Scholar were searched to identify related articles published up to January 2017. Mean ± standard deviation (SD) of changes in serum total testosterone, sex hormone binding globulin (SHBG), and free testosterone were extracted to calculate Hedges’ g to be used as effect size for meta-analysis. DerSimonian and Liard random effects model was incorporated to summarize the effects. Six clinical trials with 183 participants aged 18–41 years with follow-up period between 3–24 weeks were included. Our analysis revealed that vitamin D supplementation significantly reduces total testosterone (Hedges’ g=−0.32, 95% CI: −0.55 to −0.10; p=0.005); this effect remained significant in single group trials after subgroup analysis. Vitamin D supplementation did not affect serum free testosterone (Hedges’ g=−0.21, 95% CI: −0.44 to 0.079; p=0.08) or SHBG levels (Hedges’ g=0, 95% CI, 0.22–0.22; p=0.98). The present systematic review and meta-analysis revealed that vitamin D supplementation might significantly affect serum total testosterone while it is not effective in improving other markers of androgenic profile. Future double-blind, placebo-controlled clinical trials are highly recommended.No Full Tex
