Background and Objective: Infantile colic which can cause nervousness and anxiety in parents by fussing and restlessness in babies. This study was done to determine the prevalence and associated risk factors of infantile colic in Babol, the North of IRAN.
Methods: This descriptive-analytical study was done on 591 breastfeeding babies (321 females, 270 males) born with birth weight 2500-4000 grams and gestational age ≥37 weeks without any medical problem during 2016-18. They visited in age 2, 4, 8, 12 weeks by neonatologist. On the basis of parents complain and Wessel's criteria babies were divided into three groups: Cramp with crying (colicky group), Cramp without crying and normal group. Then possible risk factors of infantile colic have been compared in three groups.
Results: 45.5% of babies presented cramp with crying as colic group. Time of restlessness was significantly more than morning during night and afternoon (P<0.05). Colic was higher in infants born by cesarean section (P<0.05), and in the first-born child (P<0.05). However, there was not significant relation with gender, mothers’ education, parents smoking and taking dairy product.
Conclusion: According to this study’s findings, nearly half of infants had the symptoms of colic, which was higher in first children, infants born by cesarean section and during night.

Background and Objective: Obesity and overweight, one of which symptoms is chronic inflammation, is associated with changes in tryptophan metabolism, culminating in numerous diseases. Sport training is among the ways to control obesity and overweight. This study was conducted to determine the effect of eight weeks of endurance training on amino acid tryptophan serum levels and body mass of overweight women.
Methods: This quasi-experimental study was conducted on 24 overweight women in two groups of 12 people, including the control and experimental groups. The mean age and standard deviation of the control and experimental groups were 41.16±3.45 and 41.08±2.93 years, respectively. The body mass was measured using the anthropometric device, and blood samples were taken in the pre-test and post-test in a 12-hour fasting condition. The subjects of the experimental group underwent endurance training 3 sessions a week for 8 weeks with an intensity of 60% to 75% of the maximal heart rate reserve. Serum tryptophan level was measured by enzyme-linked immunosorbent assay (ELISA) method.
Results: Eight weeks of endurance training led to enhancing serum tryptophan levels, reducing fat mass, and reducing body mass index (BMI) (P<0.05), and also resulted in a statistically insignificant increase in fat-free mass in overweight women.
Conclusion: Eight weeks of endurance training could be effective in improving the physiological status and body composition of overweight women.
