- Being taller is associated with enhanced longevity, and higher education and earnings. We reanalysed 1472 population-based studies, with measurement of height on more than 18.6 million participants to estimate mean height for people born between 1896 and 1996 in 200 countries. The largest gain in adult height over the past century has occurred in South Korean women and Iranian men, who became 20.2 cm (95% credible interval 17.522.7) and 16.5 cm (13.319.7) taller, respectively. In contrast, there was little change in adult height in some sub-Saharan African countries and in South Asia over the century of analysis. The tallest people over these 100 years are men born in the Netherlands in the last quarter of 20th century, whose average heights surpassed 182.5 cm, and the shortest were women born in Guatemala in 1896 (140.3 cm; 135.8144.8). The height differential between the tallest and shortest populations was 19-20 cm a century ago, and has remained the same for women and increased for men a century later despite substantial changes in the ranking of countries.

Low back pain in relation to lumbar disc degeneration

- STUDY DESIGN: Cross-sectional magnetic resonance imaging (MRI) study. OBJECTIVES: To study the relation of low back pain (LBP) to disc degeneration in the lumbar spine. BACKGROUND DATA: Controversy still prevails about the relationship between disc degeneration and LBP. Classification of disc degeneration and symptoms varies, hampering comparison of study results. METHODS: Subjects comprised 164 men aged 40-45 years-53 machine drivers, 51 construction carpenters, and 60 office workers. The data of different types of LBP, individual characteristics, and lifestyle factors were obtained from a questionnaire and a structured interview. Degeneration of discs L2/L3-L5/S1 (dark nucleus pulposus and posterior and anterior bulge) was assessed with MRI. RESULTS: An increased risk of LBP (including all types) was found in relation to all signs of disc degeneration. An increased risk of sciatic pain was found in relation to posterior bulges, but local LBP was not related to disc degeneration. The risks of LBP and sciatic pain were strongly affected by occupation. CONCLUSIONS: Low back pain is associated with signs of disc degeneration and sciatic pain with posterior disc bulges. Low back pain is strongly associated with occupation.

- OBJECTIVES: The aim was to study risk factors of lumbar disc degeneration demonstrable with magnetic resonance imaging (MRI) with special emphasis on occupational load and back accidents. METHODS: The subjects in this cross-sectional study were 53 machine drivers, 51 construction carpenters, and 60 municipal office workers aged 40-45 years. Data on possible risk factors were available from current structured questionnaires and for 4 and 7 years in retrospect. The prevalence of lumbar disc degeneration L2/L3-L5/S1 was determined with MRI. RESULTS: An increased risk was found for posterior disc bulges among the carpenters and for anterior disc bulges among the machine drivers, but decreased signal intensity was not related to occupation. Car driving was also associated with anterior disc bulges. All signs of disc degeneration were related to a history of back accidents. Disc degeneration was not related to body height, overweight, smoking, or the frequency of physical exercise. CONCLUSIONS: Occupational load affects the risk of disc degeneration of the lumbar spine. Accidental back injuries and motor vehicle driving are associated with an increased risk of disc degeneration. Anterior and posterior disc bulges seem to be related to different types of physical loads.

- Purpose: For work disability research to have an impact on employer policies and practices it is important for such research to acknowledge and incorporate relevant aspects of the workplace. The goal of this article is to summarize recent theoretical and methodological advances in the field of Implementation Science, relate these to research of employer disability management practices, and recommend future research priorities.Methods: The authors participated in a year-long collaboration culminating in an invited 3-day conference, “Improving Research of Employer Practices to Prevent Disability”, held October 14–16, 2015, in Hopkinton, MA, USA. The collaboration included a topical review of the literature, group conference calls to identify key areas and challenges, drafting of initial documents, review of industry publications, and a conference presentation that included feedback from peer researchers and a question/answer session with a special panel of knowledge experts with direct employer experience.Results: A 4-phase implementation model including both outer and inner contexts was adopted as the most appropriate conceptual framework, and aligned well with the set of process evaluation factors described in both the work disability prevention literature and the grey literature. Innovative interventions involving disability risk screening and psychologically-based interventions have been slow to gain traction among employers and insurers. Research recommendations to address this are : (1) to assess organizational culture and readiness for change in addition to individual factors; (2) to conduct process evaluations alongside controlled trials; (3) to analyze decision-making factors among stakeholders; and (4) to solicit input from employers and insurers during early phases of study design.Conclusions: Future research interventions involving workplace support and involvement to prevent disability may be more feasible for implementation if organizational decision-making factors are imbedded in research designs and interventions are developed to take account of these influences.

- Abstract Valtonen KM, Goksör L-Å, Jonsson O, Mellström D, Alaranta HT, Viikari-Juntura ER. Osteoporosis in adults with meningomyelocele: an unrecognized problem at rehabilitation clinics. Objectives To assess the prevalence of osteoporosis and osteopenia in adults with meningomyelocele and to explore whether neurologic level, ambulatory status, and other medical problems are associated with bone mineral density (BMD). Design A cross-sectional study, including a self-administered questionnaire and clinical assessment. Setting Outpatient referral clinic in Sweden. Participants Twenty-one adults (mean age, 30y) with meningomyelocele admitted to the Young Adult Teams in Göteborg and Bo̊ras, Sweden. Interventions Not applicable. Main Outcome Measures BMD in the lumbar spine and hip and forearm measured with dual x-ray absorptiometry. Results Seven (33%) subjects had osteoporosis in at least 1 of the measured sites. Three patients had osteopenia and 2 had osteoporosis in the lumbar spine. Among the 15 subjects whose BMD of the hip region could be reliably measured, 7 (47%) had osteoporosis in the femoral neck or trochanteric region of the hip. Subjects with other medical problems commonly occurring in meningomyelocele had lower BMD in the femoral neck and trochanteric region of the hip than subjects without such factors. Ambulation alone showed only a tendency to be associated with BMD of the femoral neck, whereas the effect of other medical risk factors on BMD of the femoral neck was stronger among the nonambulators than the ambulators. Conclusions Our results show that osteoporosis is a medical problem to be considered when treating and rehabilitating patients with meningomyelocele.
