Factors associated with the development of pressure ulcers after spinal cord injury.

STUDY DESIGN: Cross-sectional observational study. OBJECTIVES: To examine variables associated with the development of pressure ulcers in subjects with spinal cord injury (SCI). SETTING: SCI patients under coverage of the State Welfare Organization of Iran. METHODS: Mobile rehabilitation teams gathered data from 20 of the 30 provinces in Iran. There were 8104 SCI patients registered in the database; 7489 patients were included in the analysis. The prevalence of PU in patients aged <10 years was lower than those aged >10; therefore, we used different logistic models for these groups. Likewise, separate models were created for patients who had experienced SCI during the past year versus patients injured >1 year before the evaluation. RESULTS: PU was present in 34.6% of the patients. The variables associated with PU in patients aged <10 years were female gender and the time passed since SCI. In patients aged >11 years, male gender, the time passed since SCI, lower level of education, lack of an intimate partner, quadriplegia and older age presented a significant association with PU. Patients for whom <1 year has passed since SCI, male gender, quadriplegia and older age were associated with PU. And patients for whom >1 year had passed since SCI, male gender, quadriplegia, older age, lower level of education and lack of an intimate partner were associated with PU. CONCLUSION: SCI patients are a heterogeneous group and the risk factors associated with PU may vary in specific subgroups. Different models are needed to describe PU in SCI patients depending on the patient's age and the time passed since SCI.

Opium use in a rural area of the Islamic Republic of Iran.

Because of its geographic proximity to the major drug production centres, there is easy access to narcotic drugs in the Islamic Republic of Iran despite efforts by governmental and nongovernmental organizations. Using a structured questionnaire as a basis for conversation, local health workers interviewed 310 residents of a rural area in Babol province about opium use. The self-reported rate of opium use, adjusted due to a bias in the sex ratio of the sample, was 8.9%. All the 42 opium users reported opium use at least 2-3 times per week in the previous 3 months. Opium was smoked by 95.2% and taken orally by 4.8%; there was no injecting use. There was no reported use of other substances, including alcohol. There was a statistically significant relationship between opium use and male sex, unemployment and cigarette smoking.
