There are few research studies evaluating the significance of low back pain (LBP) in Iran, even though the majority of locally published surveys are written in the Persian language. In the present review study, we aimed at appraising published articles related to the burden of LBP and its divergence among different jobs.
A comprehensive search was conducted in all accessible national and international electronic databases from 1948 to mid-2012. The international electronic databases were MEDLINE (PubMed), Web of Sciences, Google Scholar, Scopus, CINAHL, and the Iranian equivalents were SID, IRANDOC, IranMedex, and Magiran. The main search terms were musculoskeletal disorders, musculoskeletal symptoms, low back pain, back pain, and Iran. All keywords were searched electronically by three Boolean operators. The inclusion criteria were age ≥10 years, study focus on LBP prevalence, inclusion of both genders, and no limitation to the study design. A dedicated STROBE questionnaire was developed as a critical appraisal tool and the quality of the identified literature was examined according to the 5-point Linker scale. Articles scoring ≥3 on the Linker scale were appraised. Each literature was screened by four reviewers independently and possible disagreements were streamlined in a joint review meeting. The extracted data were entered into a dedicated table using Microsoft Office Excel program. Data were analyzed for homogeneity using the STATA software (version 11).
Of the 51 articles that were included in the present review study, 35 articles reported 1-year LBP with Nordic questionnaire and 3 articles reported point prevalence of LBP. The calculated global prevalence of 1-year LBP in workers was 25% and LBP was the most prevalent issue among health care workers. There was no association between the prevalence of LBP and job classification among workers.
LBP is the most common issue among health care workers. It is recommended that future research should focus on this job category for investigating LBP prevalence. This allows parameters that increase the frequency of LBP to be assessed and subsequently permits the reduction or elimination of such factors.

Scuba divers work in high pressure conditions which may cause some changes in physiological status to adapt to this situation. In this study, the carotid intima-media thickness (CIMT) was assessed in divers as a risk factor of cerebrovascular and cardiovascular disorders. This historical cohort study was performed on 16 male professional scuba divers as case group and 30 healthy people as controls with age range of 26-66 years. CIMT of both carotids of supine participants was measured by a 10 MHz linear ultrasonic probe quantitatively. Relationship between experience of diving and carotid IMT was evaluated. All the participants were males (mean age 42.9 ± 10.58. and for the control group was (47.05 ± 12.31 years). The mean right CIMT in divers and control group was 524.31 ± 149.40 and 443.66 ± 59.62 micrometer, respectively. Furthermore, the mean left CIMT in divers and control group was 624.57 ± 116.15 and 458.44 ± 49.56 micrometer, respectively. The findings demonstrated that long-term occupational diving leads to increased intima-media thickness in scuba divers.

Chronic pain is a frequent disability that negatively affects patient’s quality of life. Understanding of the possible relation between sociodemographic and medical variables with Health Related Quality of Life (HRQL) may help identifying the multidimensionality of pain and risk factors that limit physical and psychological adjustment of the patients. The present study was done to find these possible relationships, based on using Medical Outcomes Survey-Short Form (SF-36). Among the patients who were referred to pain clinic of Iranian Pain Society, 101 consecutive outpatients were select based on the defined inclusion and exclusion criteria. All the participants in this study orally satisfied and were fully informed by a check list and SF-36 questionnaire. The possible impact of demographic variables, characteristics, diagnosis, analgesic use, smoking and opium addiction were collected as the first part of a routine pretreatment evaluation. Our findings showed significant relation between HRQL and gender (P<0.05), the rate of chronic pain in female was higher than male, and same results found for elderly patients compared to younger ones. Our findings also showed significant relation between employment and intensity of pain (p=0.001) as, employed patients showed less physical and psychotic problems than unemployed ones. The mean average of intensity of pain in these patients was 7.5±2.2; few patients used alcohol (4%), opium (1%) and cigarette (10%). Large number of participants used analgesic (%78.2). No significant difference between sociodemographic features with pain duration and quality of life was found. In contrast our data showed significant difference between pain intensity and quality of life (p<0.001). Based on our findings it could be concluded that chronic pain in Iranian patients certainly leads to poor HRQL, the state is more serious in the elderly and female patients. Thus, in order to re-socialize the patients suffering chronic pain and decrease the impact of their pain on their life, these findings should be considered in any kind of pain relief therapy.
