To identify the effects of mindfulness meditation on older adults with chronic low back pain (CLBP), we conducted a qualitative study based on grounded theory and used content analysis of diary entries from older adults who had participated in a clinical trial of an 8-week mindfulness meditation program. Participants were 27 adults > or = 65 years of age with CLBP of at least moderate severity and of at least 3 months duration. We found several themes reflecting the beneficial effects of mindfulness meditation on pain, attention, sleep, and achieving well-being. Various methods of pain reduction were used, including distraction, increased body awareness leading to behavior change, better pain coping, and direct pain reduction through meditation. Participants described improved attention skills. A number of participants reported improved sleep latency as well as quality of sleep. Participants described achieving well-being during and after a meditation session that had immediate effects on mood elevation but also long-term global effects on improved quality of life. Several themes were identified related to pain reduction, improved attention, improved sleep, and achieving well-being resulting from mindfulness meditation that suggest it has promising potential as a nonpharmacologic treatment of chronic pain for older adults. ⋯ Community-dwelling older adults with chronic low back pain experience numerous benefits from mindfulness meditation including less pain, improved attention, better sleep, enhanced well-being, and improved quality of life. Additional research is needed to determine how mindfulness meditation works and how it might help with other chronic illnesses.

Clinical Trial
Ethnic differences in pain perception and patient-controlled analgesia usage for postoperative pain.
There are reports suggesting that sensitivity to and tolerance of both clinical and experimental pain differ among ethnic groups. We examined self-rated pain score and morphine usage in 1034 women who underwent elective lower cesarian section (LSCS) for their deliveries. Data on pain scores and amount of total morphine use according to patient-controlled analgesia were collected every 4 hours. Overall, lowest pain scores were recorded 12 hours after surgery and highest at 24 hours. Morphine consumption was highest within the first 4 hours and lowest between 12 and 16 hours. There were statistically significant ethnic group differences in pain scores (P = 1.7 x 10(-7)) and morphine usage (P = 2.8 x 10(-15)) between ethnic groups, with Indians having the highest mean pain score and using the highest amount of morphine. The ethnic differences in pain score and morphine self-administration persisted after controlling for age, body mass index, and duration of operation. ⋯ Our findings of highly significant ethnic group difference in self-reported pain level and the amount of analgesia self-administered may have implications on optimal management of acute postoperative pain. Inadequate management of pain after cesarian deliveries might affect the emotional well-being and physical recovery of patients and affect mother-child bonding.
