Comparative Study
Backpack-related musculoskeletal symptoms among Nigerian secondary school students.
Musculoskeletal discomfort in schoolchildren is significantly related to the weight and mode of carrying backpack to school. Prevalence and patterns of musculoskeletal discomfort among Nigerian secondary school students carrying backpack was investigated. Systematic sampling technique was used in the selection of the participating junior secondary schools for this study. ⋯ Prevalence of shoulder pain was high, particularly among the girls, in this sample. We suggest that factors other than the weight of backpack may predispose to musculoskeletal pain. Parents, teachers and clinicians can influence the mode of carrying backpack by secondary school students.

The findings of association between alcohol consumption and arthritis are mixed while little is known about age differences in the associations of mental health and behavioral factors with arthritis. This study aimed to estimate the prevalence and associated factors of arthritis among US adults using data from the 2012 National Health Interview Survey. In total, 8,229 adults with arthritis and 26,256 controls were selected from the adult respondents. ⋯ Stratified by age, SPD was associated with arthritis only in young adults (18-49 years old) while the ORs of anxiety and depression with arthritis decreased as age increased. Alcohol consumption revealed stronger associations in middle-aged adults and elderly. Using a large nationally representative sample in the USA, alcohol consumption, smoking, SPD, anxiety, and depression were associated with arthritis, and the associations varied across different age groups.

Fibromyalgia may present with widespread pain and tenderness, fatigue, anxiety, and depression and is associated with a low pain threshold. The etiology of fibromyalgia is yet to be ascertained, although both genetic and environmental factors may play a role in the susceptibility of patients to fibromyalgia. Various genetic variations have been investigated to explain fibromyalgia susceptibility and differences in pain sensitivity, pain threshold, and tolerance. ⋯ The PPTs were higher in the 118 A/A genotype carrier fibromyalgia patients than in 118*/G carriers; however, the differences were not significant. As the A118G polymorphism frequency was lower in fibromyalgia patients, this polymorphism may exert a protective effect against fibromyalgia in Turkish women. However, the OPRM1 polymorphism does not have a significant effect on pressure pain and fibromyalgia severity.
