The prevalence of musculoskeletal (MS) pain has been increasing among adolescents in the last decades. This may be related to either adverse changes in lifestyle and/or the psychosocial environment. Our study analysed the psychosocial and lifestyle correlates of musculoskeletal pain progression in adolescence. ⋯ The strong overlap of emotional and behavioural problems and MS pains in adolescence requires awareness in both research and clinical work.

Long-term avoidance of painful activities has shown to be dysfunctional in chronic pain. Pain may elicit escape or avoidance responses automatically, particularly when pain-related fear is high. A conflict may arise between opposing short-term escape/avoidance goals to reduce pain and long-term approach goals to receive a reward. An inhibitory control system may resolve this conflict. It was hypothesized that reduced response inhibition would be associated with greater escape/avoidance during pain, particularly among subjects with higher pain-related fear. ⋯ The findings suggest that individuals with a stronger ability to inhibit responses in a stop-signal task are better able to inhibit escape/avoidance responses elicited by pain, in the service of a conflicting approach goal.

Multisite pain and obesity are cross-sectionally related and are common conditions that may influence each other through socio-demographic, lifestyle and/or health-related factors. The aim of the present study was to examine the cross-sectional and prospective associations between overweight/obesity and multisite pain in a general population. ⋯ Being overweight or obese was associated with future multisite pain, although the magnitude of the association was small and the dose-response relationship observed in cross-sectional analyses disappeared in prospective analyses. There was less evidence that having multisite pain was a predictor of future overweight/obesity.

Autonomic neuropathy, a relatively common complication of several chemotherapy agents, can affect the vagus nerve and its pain inhibitory capacity, thus increasing sensitivity to pain. This study aimed to evaluate the relationships between autonomic parasympathetic function and the perception of (1) spontaneous pain; (2) experimental non-painful sensations; and (3) experimental painful sensations in chemotherapy-induced neuropathy patients. ⋯ Diminished vagal function due to neuropathy is associated with, and may possibly underlie, pain disinhibition expressed as greater levels of experimental pain.

Low back pain (LBP) is a prevalent problem and tends to be socio-economically patterned. Relatively little is known about life-course socio-economic circumstances as determinants of different types of LBP. Our aim was to examine whether childhood and adult socio-economic position and social mobility are associated with radiating and non-specific LBP and sciatica. ⋯ Childhood socio-economic circumstances affect the risk of radiating LBP and sciatica in adulthood. To prevent low back disorders, early socio-economic circumstances need to be considered alongside own socio-economic position.
