Low back pain and its relationship to back strength and physical activity in children

OBJECTIVE: The objective of the study was to determine the occurrence of low back pain and its relationship to back strength and physical activity in children. METHODS AND MATERIALS: The study included 53 boys and 43 girls aged 10 to 19 years from a group of 116 children who had undergone isometric strength testing 4 years previously. No intervention was performed. Each child was asked five questions concerning low back pain. A questionnaire to quantify participation in athletic activities and manual labor was used as the basis for calculation of each child's activity level. Isometric back flexor and extensor strength were measured with the same method used 4 years previously. Statistical analyses were performed with appropriate correction for confounding factors. RESULTS: The frequency of low back pain and the relationship between low back pain and age, between low back pain and back strength, and between low back pain and physical activity were determined. There was a history of low back pain in 51%, and the frequency of low back pain in the past year was 35%. Eight percent of the children had been limited by low back pain, and 7% had seen a doctor for the pain. The first incident of low back pain occurred at a mean age of 12.3 years. The frequencies of a history of low back pain and of low back pain in the past year increased significantly with age (p = 0.02 and 0.01 respectively). Increased physical activity was significantly associated with a history of low back pain (p = 0.03), and increased back flexor strength was significantly associated with a history of low back pain and of low back pain in the past year (p = 0.03 and 0.008, respectively). The rate of low back flexor or strength over 4 years had a significantly positive association with the occurrence of low back pain in the past year (p = 0.008). CONCLUSIONS AND RELEVANCE: Low back pain is common in children, and, in contrast to adults, low back pain in these children was more common with increased physical activity and stronger back flexors. We believe the main causes of low back pain in children are musculotendinous strains and ligamentous sprains.     

Relations of shyness and low sociability to regulation and emotionality.

The relations of shyness and low sociability (i.e., the nonfearful preference to be alone) to measures of regulation and emotionality were examined. College students and (for some variables) friends reported on their relevant dispositional characteristics. In general, shyness was associated with low regulation and high negative emotionality (including intensity, negative affectivity, and personal distress), low positive affect, and low constructive coping. In contrast, low sociability was unrelated to negative emotionality; associated with low positive emotional intensity, low physiological reactivity, and high inhibition control; and correlated with low seeking of social support as a means of coping. The findings are considered within a heuristic model in which emotional reactivity and regulation are proposed as predictors of social responding.

Lactate and malate dehydrogenase and alpha-esterases in oligospermia

Lactate dehydrogenase (LDH), malate dehydrogenase, and alpha-esterase were studied electrophoretically in a total of 99 semen samples obtained from normal, vasectomized, oligospermic, and infertile males. The enzymatic patterns were compared with total sperm count and percentage sperm motility. Lactate dehydrogenase X was absent in semen samples from oligospermic as well as vasectomized males. An extra LDH band (between the second and third LDH bands) was detectable in samples which had a low sperm count but higher motility (80 to 90%). This extra band was absent in samples with higher sperm count regardless of the level of percentage motility, suggesting that the extra band possibly may be related to motility factors of low sperm count but not normal sperm count. The fastest moving alpha-esterase bands were absent in samples from oligospermic or vasectomized males. These bands were also absent in samples from infertile patients having a very low sperm count. It is not clear whether the fast-moving esterase bands are related to sperm count or possible differences in hormonal levels of individuals with low or zero sperm count samples. The patterns of malate dehydrogenase did not differ in individuals with zero, low, or normal sperm count.     

Voluntary turnover and job performance: Curvilinearity and the moderating influences of salary growth and promotions.

The relationship between job performance and voluntary employee turnover was investigated for 5,143 exempt employees in a single firm. As hypothesized, support was found for E. F. Jackofsky's (see record 1987-09010-001) curvilinear hypothesis, as turnover was higher for low and high performers than it was for average performers. Two potential moderators of the curvilinearity were examined in an attempt to explain conflicting results in the performance-turnover literature. As predicted, low salary growth and high promotions each produced a more pronounced curvilinear performance-turnover relationship. Most notably, salary growth effects on turnover were greatest for high performers, with high salary growth predicting rather low turnover for these employees, whereas low salary growth predicted extremely high turnover. Additionally, once salary growth was controlled, promotions positively predicted turnover, with poor performer turnover most strongly affected.

Cognitive efficiency modes in old age: Performance on sequential and coordinative verbal and visuospatial tasks.

In an experiment using a large set of verbal and spatial tasks requiring low or high degrees of executive control, 3 distinct age-related effects were found. The smallest effect (no slowing was tied to lexical tasks with low executive involvement, the largest deficit (age-related slowing factor of 2.2) was tied to visuospatial tasks with high executive involvement, an intermediate level of deficit (slowing factor of 1.7) was found for visuospatial tasks with low executive load and verbal tasks with high executive load. These age-related dissociations were incompatible with any "common cause" formulation. The mechanism responsible for the dissociation between verbal and visual tasks, and between low and high executive load remains to be determined. The latter may reflect capacity limits.

The Saskatchewan health and back pain survey. The prevalence of low back pain and related disability in Saskatchewan adults

STUDY DESIGN: Population-based, cross-sectional, mailed survey. OBJECTIVES: To determine the lifetime, 6-month period, and point prevalence of low back pain and its related disability among Saskatchewan adults and to investigate the presence and strength of selective response bias. SUMMARY OF BACKGROUND DATA: There have been many reports of the prevalence of low back pain in different populations, and the estimates vary widely depending on case definition. However, most studies fail to differentiate between trivial and disabling back pain, which raises the issue of the usefulness of these estimates. No studies have yet documented the prevalence of graded low back pain severity and its related disability in a North American, general, population-based survey. METHODS: The Saskatchewan Health and Back Pain Survey was mailed to a probability sample of 2184 Saskatchewan adults between 20 and 69 years of age. Fifty-five percent of the eligible population responded to the survey. Respondents were compared with nonrespondents, and the presence of selective response bias by back pain status was investigated by wave analysis. The point and lifetime prevalence of low back pain was determined by simple questions, and the 6-month period prevalence of low back pain was determined by the Chronic Pain Questionnaire. All estimates were age standardized to the Saskatchewan population. RESULTS: The authors estimate that at the time of the survey 28.4% (95% confidence interval, 25.6-31.1) of the Saskatchewan adult population were experiencing low back pain, and 84.1% (95% confidence interval, 81.9-86.3) had experienced it during their lifetime. Overall, 48.9% (95% confidence interval, 45.9-52.0) of the population had experienced low intensity/low-disability low back pain in the previous 6 months, 12.3% (95% confidence interval, 10.3-14.4) had experienced high-intensity/low-disability low back pain, and an additional 10.7% (95% confidence interval, 8.8-12.5) had experienced high-disability low back pain in the previous 6 months. There was little variation in the estimates over age groups, but women experienced more high-disability back pain than men. There was no evidence of selective response bias by low back pain status in the survey. CONCLUSION: Low-intensity/low-disability low back pain is a common problem in the general population. Approximately 11% of the adult population studied had been disabled by low back pain in the previous 6 months.
