Primary dysmenorrhea is a womanhood problem around the world and negatively affects quality of life. This study was designed to investigate the prevalence of primary dysmenorrhea and to determine the factors associated with its intensity. A cross-sectional study was carried out among 311 undergraduate female students aged 18 to 27 years in Isfahan University of Medical Sciences, Iran. Socio-demographic characteristics and menstrual factors were obtained through interviews with the help of a pretested questionnaire. The prevalence of primary dysmenorrhea was 89.1%. Residing at home, younger age, lower number of years of formal education for the mother, positive family history of dysmenorrhea, higher severity of bleeding, and shorter menstrual period intervals were significantly associated with the higher intensity of primary dysmenorrhea. Primary dysmenorrhea is a common health concern among young women. Being aware of the factors that are associated with its intensity makes it possible for health professionals to organize better focused programs to reduce the adverse effects of dysmenorrhea.

Recent studies have suggested some beneficial effects of probiotics on controlling excess weight in adults; such experience is limited in the pediatric age group. This study aimed to assess the anti-obesity and lipid-lowering effects of a synbiotic supplement among children and adolescents. We conducted a randomized triple-masked controlled trial among 70 participants aged 6-18 years with body mass index (BMI) equal or higher than 85th percentile. They were randomly assigned to two groups of equal number to receive synbiotic or placebo for 8 weeks. At the end of the trial, decrease in BMI Z-score, waist circumference, and waist-to-hip ratio were significantly higher in the synbiotic group than in the placebo group. Likewise, synbiotic group had significant decrease in serum triglycerides, total- and low density lipoprotein-cholesterol levels. The beneficial effects of a synbiotic supplement on controlling excess weight and some cardio-metabolic risk factors among children and adolescents can be considered in clinical practice.

PubMed, Science Direct, The Cochrane Library and Google Scholar databases were electronically searched for all relevant studies, up to November 2015. Among the 17 included studies, 3 and 10 of them were regarding the effect of dietary patterns and various food groups on TL, respectively. Also, in 4 studies, both dietary patterns and different food groups were assessed in relation to TL. Mediterranean dietary pattern was related to longer TL in 3 studies. Five studies indicated beneficial effect of fruits or vegetables on TL. In 7 studies, a reverse association between TL and intake of cereals, processed meat, and fats and oils was reported. Our systematic review supports the health benefits of adherence to Mediterranean diet on TL. Except for the fruits and vegetables, which showed positive association with TL, results were inconsistent for other dietary factors. Also, certain food categories including processed meat, cereals and sugar-sweetened beverages may be associated with shorter TLs. However, additional epidemiological evidence and clinical trials should be considered in future research in order to develop firm conclusions in this regard.

Abstract. Background and Objective: The aim of present study was to compare, and determine, the effects of a modified alternate-day fasting diet vs. calorie restriction on inflammatory indices and coagulation factors. Methods: This was a randomized clinical trial consisting of 80 metabolic syndrome patients, who were enrolled and randomly dichotomized into a modified alternate-day fasting diet or calorie restriction group for 4 months. We measured weight, body mass index (BMI), waist circumstance (WC), waist-hip-ratio (WHR) and fat mass as primary outcomes and assessed high sensitivity C-reactive protein (hs-CRP), interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α) and coagulation factors levels as secondary outcomes before and after intervention. Results: Compared to the calorie restriction diet, following a modified alternate-day fasting diet led to a greater reduction in body weight (kg) (–6.43 ± 4.34 vs –4.11 ± 4.27; P = 0.02), BMI (kg/m2) (–3.19 ± 2.90 vs –1.43 ± 2.72; P = 0.01), fat mass (kg) (–4.88 ± 2.09 vs –3.72 ± 2.43; P = 0.03), WC (cm) (–5.57 ± 5.64 vs –2.32 ± 5.95; P = 0.01) and WHR (–0.05 ± 0.06 vs –0.02 ± 0.07; P = 0.04). Furthermore, a greater change was found in hs-CRP levels (mg/L) (–2.06 ± 1.18 vs –0.97 ± 0.82; P = 0.03), prothrombin time (s) (1.41 ± 2.34 vs –0.41 ± 2.17; P < 0.001), activated partial thromboplastin time (s) (0.26 ± 3.70 vs –1.78 ± 3.56; P = 0.04) in modified alternate-day fasting diet when compared to calorie restriction diet. However, there was no difference in TNF-α or IL-6 and fibrinogen between groups (P > 0.05). Conclusions: These findings suggest that a modified alternate-day fasting diet can be a beneficial alternative for the management of body weight, fat mass and WC as well as hs-CRP and coagulation factors levels among metabolic syndrome patients.
