Background & Objective: Low back pain is a common complaint that many people face throughout their lives. It is one of the most costly health problems. The aim of this study was to determine the prevalence of low back pain and risk factors for lifestyle in opioid users and non-opioid drug users in the population of Fasa Persian cohort.
Materials & Methods: The research method was cross-sectional-descriptive-analytical and the statistical population of the study was the residents of Sheshdeh in Fars province among whom 10,000 people were selected by census method. The instrument used was a national cohort questionnaire and in order to analyze the data, descriptive statistical tests, chi-square, independent t-test as well as logistic regression were used to model and estimate the odds ratio (OR) in SPSS24 software.
Results: The results showed that there was a statistically significant relationship between low back pain and opium, hookah, cigarette and alcohol consumption (P <0.000). With increasing one year of age, the chance of low back pain increases 1.02 times (CI = 1.019-01.191, OR = 1.02). Also, women have 1.67 times more chance of low back pain (CI = 1.44 / 1.94, 67 OR = 1.1) Moreover, people who smoke hookah have 1.43 times more back pain (CI = 0.526-0.92, OR = 1.43). The chance of low back pain in people who sneeze is 2.50 times higher (CI = 1.34-3.67, OR = 2.50). The chance of low back pain in people who smoke is 1.20 times higher (CI = 1.03-1.032 / C1, OR = 1.20) and with an increase in BMI, the chance of low back pain in people increases by 1.017 times (029 / 1-017 / 1 = CI, 017/1 = OR).
Conclusion: The results of the present study showed that there is no difference between opioid (opium) and non-opioid drugs (cigarettes, hookah, nasal sprays and alcohol) with low back pain and these substances decreased calcium levels due to their effect on the musculoskeletal system and increased bone mass density and eventually lead to low back pain in consumers.
 

Background & objective: Chronic low-back pain is one of the most common disorders associated with chronic pain and is one of the costliest health care problems. The aim of this study was to investigate the relationship between back pain and physical activity in different occupations.
Materials & Methods: The research method was cross-sectional, descriptive-analytic and the statistical population of the study was the residents of Shashdeh in the city of Fasa in Fars province among whom 10,000 people were selected by census method. The instrument used was a national cohort questionnaire. To analyze the data, descriptive statistical tests, chi-square, independent t-test as well as logistic regression were used to model and estimate the odds ratio (OR) in SPSS-24 software.
Results: The mean and standard deviation of age of the participants in the study was 48.64 (9.57) and 54.8% of the study population were women. There was a significant difference between gender and low-back pain (P <0.000). With increasing one year of age, the chance of low-back pain increases 1.025 times (CI = 1.019 / 1.019 / 1.01, OR = 1.025). and people with heavy work status were 1.52 times more likely to have low-back pain compared with housewives (CI = 1.255 / 1-253, OR = 1.52)
 
Conclusion: Based on the results, it is suggested that intervention measures be taken to prevent low-back pain so that these disorders can be controlled in the future. Also, by training all people to perform physical activity and the principles of ergonomics in the workplace, it helps to improve the physical and mental health of people and causes better performance.

Background & Objective: Some studies have demonstrated that aerobic exercise can reinforce antioxidant defensive system. To this end, the present study aimed to compare the effect of maximal and submaximal aerobic physical activity on saliva enzymatic and non-enzymatic antioxidant indices in middle-aged women.
Materials & Methods: In this quasi-experimental study, 24 women (35-45 years, Weight: 67.41±5.03, Height: 161.83±2.98 and BMI: 25.74±2.01) were selected purposefully and voluntarily who were randomly categorized into two groups, Maximal Aerobic Physical Activity (MAPA) and Submaximal Physical Activity (SAPA) (n=12/group). SAPA were done with 50 to 70 percentage of heart rate reserve for 3 sessions/week for 6 weeks. To do MAPA, Bruce Protocol (seven stages for 3 minutes) was applied. It started with 10% incline and 1.7 miles/hour speed and continued with 2% increase for every 3 minutes until exhaustion, 3 sessions/week for 6 weeks. Required saliva samples were gathered before the first session and 24 hours after the last session of exercise to be applied to evaluate Catalase, Superoxide dismutase, Malondialdehyde enzyme, and total antioxidant capacity. Data were analyzed using an independent T-test (P≤ 0.05).
Results: Research results represented a significant difference in saliva enzyme indices for MAPA and SAPA groups: Catalase (P_CAT= 0.003), Malondialdehyde (P_MDA=0.001), and total antioxidant capacity (P_TAC= 0.04). MAPA group showed higher average. In addition, the results indicated no significant difference in dismutase superoxide enzyme levels (P_SOD=0.88) in MAPA and SAPA groups.
Conclusion: According to the reported results, it may be concluded that due to its ability to increase antioxidant enzyme secretion, MAPA is applied to cope with oxidative stress.

Background & Objective: Decreased levels of physical activity during the COVID-19 epidemic can cause physical and psychological problems for the individual. Therefore, the aim of this study was to evaluate the relationship between physical activity and control coping styles in the face of the Covid-19 epidemic in Ahvaz, Iran.
Materials & Methods: This study is a descriptive-analytical cross-sectional study and the research population includes females in Hamidiyeh Ahvaz, Iran, who were studying in 2019-2020. In this regard, 208 females were selected based on Cochran's formula and random sampling for participation in the study. Beck's physical activity questionnaires and Coping Styles Questionnaire in the face of the COVID-19 epidemic were used to collect data. Pearson correlation coefficient was used to establish statistical relationships.
Results: The results only showed a significant relationship between social support coping style and physical activity (physical activity related to leisure time) (r= 0.142, p= 0.044). There was no significant relationship between physical activity (related to work, sport, leisure time and total) and any of the other coping styles (Confrontation, Avoidance, Self-control, Responsibility, Escape and avoid, Problem solving, Positive estimation) (p≥0.05).
Conclusion: During the COVID-19 epidemic, physical activity related to leisure time was positively associated with social support coping style but all other cases we did not observe a significant relationship between physical activity and coping styles with Covid-19.

Background & Objective: The cesarean section increases worldwide and has many side effects, including acute pain. This study investigated the relationship between physical activity during pregnancy, analgesic consumption, and maximal postoperative pain in women with low segment cesarean section.
Materials & Methods: 340 Cesarean section women were interviewed by demographic and global physical activity questionnaires during the pre-operative visits. The participants were categorized into high, moderate, and low physical activity groups (high PA, moderate PA, low PA, respectively) according to the global physical activity questionnaire guidelines. The maximal postoperative pain (MPP), the type, and doses of analgesia used/2 days were recorded. Pearson correlation, Chi-square, and one-way ANOVA were used to analyze the data.
Results: MPP was reduced in the high PA group (5.48 ±1.72) compared to the moderate (6.46±1.30) and low PA groups (6.97±1.92; p<0.0005, p<0.0005, respectively). There was a difference between the moderate and low PA groups (p=0.04). Paracetamol was the common analgesic without significant difference among groups (p=0.37). The numbers of paracetamol doses significantly reduced in the high PA group (3.31±1.65) compared to the low PA group (4.03±2.01, p=0.01). MPP had a significant and low negative correlation with total physical activity (r=-0.25, p=0.0005). There was a negative significant correlation between occupation (r=-.491, p=0.0005), recreational (r=-.262, p=0.0005), and travel activities (r=-.150. p=0.006) with MPP. There was a low positive correlation between sedentary activity and MPP (r=0.23, p=0.0005).
