RESUMEN
Factors associated with self-reported back pain were investigated using questionnaire data on 407 female nurses from a large hospital in Athens, Greece. Factor analysis was used to construct indices of pain and its impact on normal life, and also to summarize work load descriptions. Pain factors were examined in relation to work load and personal characteristics by logistic regression. Statistically significant items, in relation both to pain and impact, were the existence of previous back injury, self-reported headaches and the 'carrying and lifting' factor of work load which principally included moving equipment. Age, height and weight were not associated with back pain. Compared to a similar study by Harber and colleagues in California, United States of America, the factors associated with back pain were quite similar in this study even though the prevalence of back pain was much higher among Greek nurses and their work load was physically much more demanding.

The prevalence of occupational low-back pain was investigated in 407 female nurses in a large tertiary health care unit in Athens, Greece. Work-related back pain within the previous 2 weeks was reported by 63% of respondents and within the previous 6 months by 67%. Prevalence was higher (66% in the previous 2 weeks) in the wards with physically heavy duties than in the rest (52%, P = 0.003), but all grades of nursing staff were affected equally. The specific factors which claimed to be responsible for causing back pain included moving heavy items (36%), lifting patients onto trolleys (32%) or in bed (29%), helping patients out of bed (24%) and bending to lift objects from the floor (24%). Absence from work because of back pain in the previous 2 weeks was reported by 28% of the sample.

Creatine kinase-brain isoenzyme activity (CK-BB) was measured longitudinally in the serum of 31 pregnant women in the first stage of labor (early and advanced), at delivery, and 1, 6 and 24 h after delivery, in the umbilical cord and in the serum of their neonates on the first day of life. There was no increase in serum CK-BB values of mothers that delivered normally (n = 15) or had an elective cesarean section (n = 5). Pregnant women with signs of fetal distress had an increase in CK-BB levels in the first stage of labor (mean +/- SD 4.5 +/- 4.9 U/l, p < 0.03) and 6 h after delivery (12 +/- 4 U/l, p < 0.0001). Neonates with intrauterine stress also had an increase in their CK-BB to 144 +/- 116 U/l at 6 h of life, in comparison with babies born without signs of stress. It appears that CK-BB during labor and in the first hours of life may be indicative of intrauterine stress.
