Introduction: Cyclic mastalgia is a common cause of anxiety among women that leads to a health care centers. Because of some characters, it is important to advice correct cure.Objective: Evaluation of correlation between BMI and cyclic mastalgia in 20 years old to premenopausal women.Materials and Methods: This was a case- control study that has been done on 102 women in Navab clinic of Qazvin. They were divided into two groups of 51 members: case group with cyclic mastalgia and control group with normal women. Duration and intensity of pain was evaluated by visual analog scale (VAS) and breast pain chart. BMI (Body Mass Index) was determined in two groups and then they were compared. Data was analyzed by T test and chi square. Results: Mean age of two groups were 31/2 and 31/5, that there was no statistically significant difference. Range of BMI in case group was 21-36 and in control group was 20-30 .Mean of BMI in case group was 28.81 +3.22 and in control group was 25.14+ 2.19. That showed significant statistically difference, (p= 0.000).Conclusion: This study showed that BMI of control group without mastalgia was in normal range. BMI of case group with mastalgia was in abnormal range and significantly was higher than control group.

Objective(s): To determine the role of mother's BMI on pregnancy outcomes.Methods: This was a cross-sectional study of 294 pregnant women aged 18-35 years, with term cephalic presentation, singleton attending to Barn maternity hospital for childbirth related to their BMI they were grouped as: underweight (BMI<19.8), normal (19.8<BMI<26) and overweight (BMI>26). Data were collected by a questionnaire and were analyzed descriptively.Results: The mean of first phase of delivery in underweight women was (7/73±5/77) minutes more than of over weight women (3/32±5/11) minutes. This difference was not statistically significant. The mean of third of delivery in normal weight was more than of under and overweight women, but not statistically significant.The mean of babies weight in over weight was more than of in under and normal weights, but the mean of APGAR Scores in over weights was low. The cesarean rate in over weights was 28.9%, in normals was 15.2% and in under weights was 4.5%. These differences were statistically significant. Conclusion: The findings suggest there is need to advise women to keep their weight normal before and during pregnancy to prevent adverse outcomes.

Introduction: Acne is one of the most common diseases in dermatology. It has been claimed that acne and weight gain are clinical markers of hyperandrogenism, and it seems that obesity is associated with increased responsiveness to androgenic hormones and acne severity. This investigation may aid in finding the possible relationship between severity of acne and Body Mass Index (BMI) in order to improve the management of acne patients.Methods: This was a case-control study. After signing a consent form, 220 individuals that had referred to the outpatient clinic of dermatology of Hamadan Farshchian Hospital were recruited. All of the participants in the study population were females. There were a total of 110 patients with acne serving as the case group and 110 females, without acne as the control group. Two groups were age-matched and compared with respect to BMI.Results: There was a significant relationship between weight and acne (P=0.001), yet no correlation was found between acne severity and BMI (P=0.348).Conclusion: This study showed that acne and weight are related. Since overweight and metabolic syndrome is associated with higher risk of cardiovascular disease and diabetes, identification and treatment of obesity in these patients is essential. Therefore, it could be suggested that control of obesity and metabolic syndrome may also improve management of acne patients.

Objectives: To compare BMI and inverted BMI in evaluating body measurement, resting blood pressure, Dual energy X-ray absorptiometry (DEXA) parameters of fat mass and metabolic risk factors in Iranian children Materials and Methods: This is a cross-sectional study on 477 children aged 9-18 years in the South of Iran. Weight, height, resting blood pressure, waist and hip circumference and pubertal stage of all participants was measured with standard methods. DEXA was used to determine body composition index. Blood samples were checked for serum lipid profiles and fasting blood sugar (FBS). Metabolic risk score (MRS) was calculated by the summation of the Z-scores for TC, TG/HDL, LDL, systolic blood pressure, and waist circumference minus HDL Z-score. Results: BMI did not have a normal distribution in our participants but iBMI had a normal distribution. IBMI had more significant correlation with waist to hip ratio and systolic blood pressure (r2=0. 053 and r2=0. 182) than BMI (r2=0. 041 and r2=0. 101). MRS had a positive correlation with BMI (P<0. 05, r=0. 466) and a negative correlation with iBMI (P<0. 05, r=-0. 458) in all children and both genders. Android/Gynecoid ratio had a positive correlation with BMI (P<0. 05, r=0. 497) and a negative correlation with iBMI (P<0. 05, r=-. 649). Fat mass index had a significant correlation with both BMI (P<0. 05, r2=0. 589) and iBMI (P<0. 05, r2=0. 541). Conclusion: This study revealed that iBMI could be a suitable alternative for BMI in estimating waist to hip ratio, resting systolic blood pressure, FBS, lipid profiles, fat mass index, Android/ Gynecoid fat ratio, and metabolic risk score. Because of normal distribution of iBMI, it is more reliable than BMI for use in statistical analysis.

This study examined the acute hormonal and myokine responses to traditional and circuit resistance training in young males with distinct BMI-based groups. Twenty sedentary men aged 20–30 years were classified as high-BMI (BMI >29.9) or low-BMI (BMI <18.5). Each participant completed both traditional resistance training (TRT) and circuit resistance training (CRT) protocols in a crossover design, with a one-week washout period. Sessions included multi-joint upper and lower body exercises at comparable intensities. Blood samples were taken immediately before and after each session. Serum levels of testosterone, cortisol, myostatin, and follistatin were assessed using ELISA kits. A repeated-measures ANOVA was used to compare within- and between-group changes across time and training modality. Baseline cortisol levels were significantly higher in low-BMI individuals (P=0.037), while testosterone levels showed no initial difference between groups (P>0.05). Post-TRT, testosterone levels increased significantly in high-BMI individuals compared to low-BMI individuals (P=0.017), with both training types elevating testosterone and cortisol across all participants (P<0.05). CRT led to a significant reduction in myostatin and increase in follistatin in high-BMI individuals (P<0.05), while only follistatin increased significantly in low-BMI individuals after TRT (P<0.05). These results suggest that CRT promotes superior anabolic signaling in high-BMI individuals, while TRT is more effective at enhancing testosterone response. Myokine and hormonal responses appear to be body-type-dependent and training-modality-specific. Practitioners designing hypertrophy-focused programs should tailor training protocols to the athlete’s BMI-based group to optimize muscle adaptation and endocrine outcomes. And also, trainers should individualize hypertrophy programs based on body composition to optimize both hormonal responses and muscle adaptation.

Background and Objective: BMI is the most important international indexes for physical health assessment and it is a tool for awareness about optimal nutrition during adolescence. The Aim of this study was a survey about the impact of nutrition on BMI of guidance school and high school students of ghaemshahr city in the academic year 2010-2011.Methods: This study is the kind of applied studies that was performed with analytical descriptive, cross-sectional method. The samples of this research were obtained through the table of Kerjcie and Morgan and cluster random sampling method and between guidance and high school students of ghaemshahr city. The volume of samples was 305 people. The collected data were analyzed using SPSS software and associated tests.Results: 52.5% of samples were male and 47.5% were female, 57% of subjects were under weight, more than 13.8% was obese and very obese, and only 29.2% of the sample have normal weight. There was a significant difference between high BMI and consuming fried foods, the speed of eating, eating while watching TV or reading, difficult and low-calorie diet, oil consumption, the number of obese people in the family, and the level of family education. But there was no correlation Between BMI and eating sandwich, chips and snack, milk, fruit juice, salads and vegetables, consumption of protein, carbohydrate, and homemade food, type of diet, the number of persons in family and the occupation of parents.Conclusion: the result of this study revealed the positive effect of education Level of parents and awareness of families about nutrition and BMI. Therefore it is necessary to increase the awareness of families about the nutrition of students.

Body mass index (BMI) is a tool for indicating weight status in adults. BMI is used as an index for determining the total body fatness or general obesity. In importance of young people health, this study was carried out to determine the rate of healthy among students of Zahedan University of Medical Sciences in 2001-2002. We chose 720 students (428 female aged 20.9±2.4 and 292 male aged 23.3±4.6 y) that were selected in stratified sampling. The results shows the Mean and SD BMI were 21.6±3.1, and 21.7±2.9, respectively, in female and male a student that statistically there was no difference between mean BMI. 18.3% of students were underweight, 12.9 were overweight and 1.3% was obese. As results show some of female and male students are in a degree of malnutrition, therefore launching nutritional programs and life style modification program are recommended.
