Considering the importance of the multidimensional character of the home environment in developmental research, especially the motor development of children, the current study examines the effect of parents' socioeconomic status, sports experience rate, and the level of physical activity on the level of motor affordances.

The research method with a cross-sectional approach was descriptive, and data collection was a survey that was conducted in 2022. Participants included 236 parents (father and mother) with children aged 18-42 months and were selected by multi-stage cluster sampling. Parents scored their physical and athletic activities based on level and background/experience. Their socioeconomic standing was determined based on their income and education. The home environment was assessed using the Persian version of the Affordances in the Home Environment for Motor Development-Self-Report (AHEMD-SR).

The results showed no significant relationship between the rate of sports experience and the level of physical activity of fathers with home motor affordances scores. However, this relationship was significant with the rate of mothers' sports experience (P<0.001, r=0.24), and motor affordances were significantly different from mothers' sports experience (P<0.001, effect size = 11%). The results showed a significant relationship between motor affordances and the mothers' level of physical activity (P<0.05, Eta = 0.21). In addition, there is a significant difference between motor affordances and the mothers' level of physical activity (P<0.05, effect size = 6%). In addition, socioeconomic status indicators had a significant effect of 44% on the level of home motor affordances (P<0.001).

Only the higher the mothers' rate of sports experience and the level of physical activity (more than two years) along with the criteria of socioeconomic status in providing and strengthening home motor affordances for children is more influential and effective. Among the different dimensions of motor affordances, the two dimensions of fine-and-gross motor toys are strongly influenced by the economic conditions of families as well as the sport's history of the mothers.

The aim of this study was to examine the level of physical literacy for 8-12 years students. The method was descriptive with field studies. The sample included all second to sixth grades in Tehran. 284 students in 8 elementary schools were selected by multistage cluster sampling. Physical Literacy Test with 4 domains of Physical competence, Daily physical activity, Motivation and self-confidence, and Knowledge and understanding was used to collect data. The results showed the low level of physical literacy for students. It was also found that there is a significant difference between the scores of physical literacy with gender, age and body mass index, so that The boys' group had higher physical literacy and As the age increased, the level of physical literacy improved, which was less than the period from the terminal Childhood to adolescence, In addition the students with obesity and overweight BMI had fewer physical literacy than those with a recommended BMI. As a result of the studies, it was found that 8-12 years students do not have an acceptable level of physical literacy. This suggests that second-grade students up to the sixth grade have an active lifestyle and consequently they are far from the active and healthy life style. And if not taking this seriously, this group's health from a society may come with different physical, emotional, psychological and motor health risks in the future

To achieve a desirable level of motor development and physical-mental competencies and develop a healthy and active lifestyle in all people in society, particularly children  and families of the military and considering the nature of job  their fathers’ job, accurate principles on motor and exercise skills, called physical literacy principles, is required.

 Present study aimed to determine the relationships between the levels of the physical literacy of children in the 8-12 age range  with  some natures of their military fathers’ job.

The method is a descriptive-correlation in which a total of 171 children in the 8-12 age range were selected by multi-stage cluster sampling in districts 1, 4, 8 and 13 of Tehran and the Iranian version of the physical literacy test consisting of 4 subscales such as physical competence, daily physical activity, motivation and self-confidence, and knowledge and understanding was administered Further, Fathers completed a questionnaire about their occupational nature, corps, and their level of education. Findings were analyzed using descriptive statistics, ETA correlation coefficient, t- independent test, and one-way covariance analysis. Data were analyzed using SPSS 23.

The physical literacy of children with staff fathers was more than those with father in the troop (Effect size=0.36, t = -4.558, P<0.01).. Furthermore, the physical literacy of children with fathers working in educational-section  was greater than those whose fathers work in operational section (P= 0/05).

Childrenchr('39')s physical literacy is related to the occupational nature of military fathers. These job natures can affect the childrenchr('39')s active lifestyles. Knowing this relationship  affects the physical literacy of children in military families and the implementation of appropriate movement and sports programs is needed to increase the physical literacy of these children, especially among girls. Further studies on the impact of other factors on physical literacy should be conducted.
