- Objective and designThe prevalence of low back pain was assessed in relation to physical activity, for both work and leisure activities, in a randomly selected population in the northern part of Sweden. Additionally, the associations between age, sex, level of education, lifestyle factors, demographic characteristics, and low back pain were evaluated. Subjects: A total of 5798 subjects aged 25–79 years were selected randomly from a geographically well-defined area in northern Sweden. Methods: Additional questions concerning people's experience of low back pain were added to the questionnaire of the World Health Organization MONICA (MONItoring of trends and determinants in CArdiovascular disease) health survey with the aim of investigating prevalence rates and factors associated with low back pain. Results: Forty-one percent of the participants reported having low back pain (of these 55% were women and 45% men). The prevalence rate was highest in the age group 55–64 years. Chronic low back pain was the most frequent occurring problem. Of those with low back pain, 43% of the women and 37% of the men reported having continuous low back pain for more than 6 months. Individuals with low back pain often experienced a more physically heavy workload at work and lower physical activity during leisure time, and they were also more likely to have been smokers, have had higher body mass index, lived in smaller communities, and were less educated than people without low back pain. Conclusion: Low back pain seems to be associated with physical activity at work and in leisure time, certain lifestyle factors and demographic characteristics.

- BACKGROUND AND PURPOSE: Although there have been numerous publications on lumbar disc herniation (LDH) treated surgically, there has been little interest in sex differences. It has been shown in many studies that sex differences may be important in certain diseases. We therefore reviewed consecutive register material from one institution for possible gender differences in pre- and postoperative parameters in patients operated for lumbar disc herniation.PATIENTS AND METHODS: Pre- and postoperative parameters for all patients operated on at the Department of Orthopedics, Lund University Hospital over 6 years (2000-2005 inclusive) (301 patients, 165 males) were analyzed regarding sex differences.RESULTS: Statistically significant and clinically relevant sex differences were found. Preoperatively, females had more pronounced back pain and disability, and also lower quality of life in some respects. At 1-year followup, females reported a higher rate of consumption of analgesics, a higher degree of postoperative back and leg pain, and less improvement regarding disability and some aspects of quality of life. Relative improvement, rate of return to work, and satisfaction with the outcome of surgery were not, however, statistically significantly different between females and males.INTERPRETATION: There are statistically significant differences between the sexes in lumbar disc herniation surgery regarding basic demographic status and postoperative status, whereas the surgical effect is similar. Further investigations should focus on whether there is a true sex difference or whether these differences are due to selection for surgery, differences in proneness to seek medical advice or to accept/choose surgery, or other unknown factors.

- A cross-sectional study to investigate regional cerebral blood flow (rCBF) in patients with chronic whiplash syndrome and chronic neck pain patients without previous history of trauma along with a healthy control group. Chronic neck pain is a common disorder and a history of cervical spine injury including whiplash trauma constitute a risk factor for persistent neck pain. The aetiology of the late whiplash syndrome is unknown with no specific diagnostic criteria based on imaging, physiological, or psychological examination. Earlier studies indicate a parieto-occipital hypoperfusion but it is unclear if the hypoperfusion represents a response to chronic pain. The rCBF was monitored in 45 patients with chronic neck pain: 27 cases with chronic whiplash syndrome and 18 age and gender matched cases with non-traumatic chronic neck pain. The rCBF was estimated with single-photon emission computed tomography (SPECT) using technetium-99m hexamethylpropylene amine oxime (HMPAO). The non-traumatic patients displayed rCBF changes in comparison with the whiplash group and the healthy control group. These changes included rCBF decreases in a right temporal region close to hippocampus, and increased rCBF in left insula. The whiplash group displayed no significant differences in rCBF in comparison with the healthy controls. The present study suggests different pain mechanisms in patients with chronic neck pain of non-traumatic origin compared to those with chronic neck pain due to a whiplash trauma.
