Introduction: Participating in regular physical activity has positive effects on the health and behavior of adolescents. Physical activity is multifaceted and has both interrelated psychological, biological and environmental effects. Therefore, this study was conducted to determine the level of physical activity of female students and its relationship with their socioeconomic status.

Methods: 630 junior high school students in Mazandaran were selected based on randomized multistage cluster sampling in the year 2017. The tools used for collecting data were pedometers, and demographic and Ghodratnama socioeconomic status questionnaires. Data analysis was done using SPSS₂₃ software with descriptive and inferential statistics (the Kolmogorov-Smirnov test, the one-way analysis of variance [ANOVA], and the Pearson correlation coefficient) at a significance level of P ≤ 0.05.

Results: The results showed that the level of physical activity of students decreased as grade level increased. An ANOVA showed a significant difference between the level of physical activity of students in 7-9 grades, but Tukey’s post hoc test showed a significant difference between the level of physical activity of 7th grade students with 8th and 9th, while the difference between the students of grades 8 and 9 was not significant statistically. Out of all students, 30.72% of students were active and 69.28% inactive. The Pearson correlation coefficient showed that there was no significant relationship between socioeconomic status and level of physical activity.

Conclusion: A vast majority of adolescent girls do not do the amount of physical activity recommended for good health, which is a worrying issue. It is suggested that relevant authorities mobilize basic strategies for changing the lifestyles of adolescent girls, including the development of a comprehensive program of physical activity by specialists.

Introduction: Regular fruit and vegetable consumption is one of the most important and preventative indicators for the development of obesity, disorders, and diseases.The aim of this study was to identify the determinants of fruit and vegetable consumption based on social cognitive theory among first-grade high school female students.
Methods: This descriptive cross-sectional study was performed on 264 high school female students who were selected through multistage random sampling from school students in Rafsanjan. The data were collected through a demographic questionnaire, the seven-day fruit, and vegetable consumption frequency, and the fruit and vegetable consumption determinants questionnaire that was developed based on the constructs of cognitive social theory. Then were analyzed using SPSS-16 software through independent samples t-test, Pearson correlation, one-way ANOVA, and multiple linear regression analysis.
Results: The average daily fruit and vegetable intakes in adolescent girls were 3.43 and 2.30 units per day, respectively. The results of multiple regression analysis showed that environmental factors and behavioral skills have a significant relationship with fruit consumption. Besides, vegetable consumption was found to have a significant relationship with behavioral skills and social reinforcement (P <0.05). In sum, the constructs of social cognitive theory explained 7.1% of the variances in fruit consumption and 9.8% of the variances in vegetable consumption.
Conclusion: The average daily fruit and vegetable intakes were less than the recommended level. It is recommended that further interventional studies be designed in order to explore environmental factors and behavioral skills based on the constructs of social cognitive theory.

Introduction: The problems of girls and boys with mild intellectually disable (MID) increases with age gradually. Due to the emerging changes, puberty is a significant period for adolescents with MID. The aim of this study to investigate sexual abuse in girls and boys with mild intellectually disable in the puberty period.
Methods: This research is a cross-sectional study. The statistical population consisted of all boys and girls with mild intellectual disabilities between the ages of 12 and 16 from exceptional public schools and their mothers in Yazd, Iran. 300 MID adolescents (150 girls and boys each) were selected by multi-stage sampling. To study sexual abuse, a self-designed questionnaire was used. The questionnaire comprised two sections. Kuder-Richardson coefficient obtained for boys and girls with MID turned out to be 0.80 and 0.84, respectively. Using frequency, percentage, and correlation coefficient (p<0.05). Data were analyzed with SPSS 24.
Results: In this study, 2.67% (n = 4) of girls and 4% (n = 6) of boys with MID were abused. Also, their psychological and physical signs of sexual abuse were assessed (depression: girls,0.75% (n = 3), boys, 33.33% (n = 2), aggression: girls,0.75% (n = 3), boys, 66.66% (n = 4),  avoiding certain adults, 0.50% (n = 2), boys, 33.33% (n = 2), sleep and eating disorder, 0.25% (n = 1), boys, 16.66% (n = 1) . Some of their parents pointed that their children had not received training in this area. There was a significant positive correlation coefficient between the mother's educational level and receiving training by schools and family with sexual abuse knowledge (p<0.05).
Conclusion: The irrational reaction of families, the community, and the lack of adequate training lead to an increasein sexual abuse in such individuals. Hence, training these young individuals seems essential both before and during puberty.
