    Abstract:

    Abstract Background Manual handling operations (Mho) are known to be risk factors for work-related upper limb disorders (WRULDs), e.g. symptoms and conditions such as carpal tunnel syndrome. To estimate the risk of WRULDs, a Key Indicator Method (KIM) for the risk assessment of Mho was developed. The method was validated in regard to different criteria, including face validity, criterion validity, reliability and further aspects concerning utility. This paper describes the KIM-Mho and criterion validity of this method with reference to prevalence of musculoskeletal disorders (MSDs). Methods A cross-sectional sample of 643 employees exposed to Mho was compared to a reference group of 804 unexposed subjects predominantly working at visual display terminals. The Nordic Questionnaire and a standardized clinical examination were used to obtain the 7-day and 12-months prevalence of symptoms and clinical conditions of the musculoskeletal system. Job specific exposure levels to Mho were assessed by ergonomists using the KIM-Mho. The resulting risk scores were categorized into risk categories 1 - low risk (reference group), 2 - increased risk, 3 - highly increased risk, and 4 - high risk. Log-linear Poisson regression models were applied to obtain adjusted prevalence ratios (PR) with 95%-confidence intervals. Results The 7-day prevalence of symptoms for subjects in risk category 3 compared to risk category 1 was significant for the regions shoulder [women (w): PR 1.8 (1.2–2.7), men (m): PR 2.3 (1.2–4.4)], elbow [w: PR 3.3 (1.5–7.2), m: PR 2.4 (0.8–7.3)], and hand/wrist [w: PR 3.0 (1.7–5.3), m: PR 5.5 (2.7–11.3)]. The 7-day prevalence of symptoms for risk category 4 was also significant for the regions shoulder [w: PR 1.9 (1.3–2.8), m: PR 1.9 (1.3–2.7)], elbow [w: PR 4.5 (2.3–8.7), m: PR 3.3 (2.1–5.4)], and hand/wrist [w: PR 4.2 (2.6–6.9), m: PR 5.5 (3.5–8.5)]. The 12-months prevalence in these joint regions show comparable increases in the risk categories 3 and 4. Conclusions The KIM-Mho is valid in regard to criterion validity. The hypothesis could be confirmed, that high risk scores were associated with an increased prevalence of symptoms and clinical conditions especially in the shoulder, elbow and hand/wrist regions among employees exposed to Mho.

  • Evaluation of objectivity, reliability and criterion validity of the Key Indicator Method for Manual Handling Operations (KIM-Mho), draft 2007
    Work, 2012
    Co-Authors: André Klußmann, Hansjürgen Gebhardt, Monika A Rieger, Falk Liebers, Ulf Steinberg
    Abstract:

    Upper extremity musculoskeletal symptoms and disorders are common in the working population. The economic and social impact of such disorders is considerable. Long-time, dynamic repetitive exposure of the hand-arm system during manual handling operations (Mho) alone or in combination with static and postural effort are recognised as causes of musculoskeletal symptoms and disorders. The assessment of these manual work tasks is crucial to estimate health risks of exposed employees. For these work tasks, a new method for the assessment of the working conditions was developed and a validation study was performed. The results suggest satisfying criterion validity and moderate objectivity of the KIM-Mho draft 2007. The method was modified and evaluated again. It is planned to release a new version of KIM-Mho in spring 2012.

The draft of the so-called Key Indicator Method for Manual Handling Operations (KIM-Mho) was developed in analogy with the existing KIM for Lifting/Holding/Carrying (KIM-LHC) and Pulling/Pushing (KIM-PP) of loads. The KIM-Mho is designed to fill the gap existing in risk assessment of manual work processes, since the existing KIMs deal only with manual handling of loads. This research project focused on the following: - Examination of the validity of workplace assessment with the KIM-Mho comparing expert ratings with the results of the observations. - Examination of the objectivity of workplace assessment with the KIM-Mho applied by different examiners. - Examination of the criterion validity of the risk assessment provided by KIM-Mho with respect to the association between exposure and the occurrence and prevalence of health related outcomes.

  • cardiovascular risk factors associated with the metabolically healthy obese Mho phenotype compared to the metabolically unhealthy obese muo phenotype in children
    Frontiers in Endocrinology, 2020
    Co-Authors: Simonetta Genovesi, Luisa Gilardini, Cecilia Invitti, Laura Antolini, Antonina Orlando, Simona Bertoli, Marco Giussani, Elisa Nava, Maria Grazia Battaglino, Alessandro Leone
    Abstract:

    : Background: In pediatric age the prevalence of obesity is high. Obese children who do not have other risk factors than excess weight have been defined as "metabolically healthy obese" (Mho). Aim: The aim of this study is to evaluate, in a population of obese children, the prevalence of the Mho and "metabolically unhealthy obese" (MUO) phenotype. Furthermore, we evaluated the distribution of Uric Acid, HOMA index and Waist-Height ratio (W-Hr) in the Mho and MUO sub-groups and the impact of these non-traditional risk factors on the probability to be MUO. Methods: In 1201 obese children and adolescents [54% males, age (±SD) 11.9 (±3.0) years] weight, height, waist circumference, systolic (SBP) and diastolic (DBP) blood pressure, pubertal status, glucose, insulin, HDL cholesterol, triglycerides and Uric Acid serum values were assessed. MUO phenotype was defined as the presence of at least one of the following risk factors: SBP or DBP ≥ 90th percentile, glycaemia ≥ 100 mg/dl, HDL cholesterol <40 mg/dl, triglycerides ≥100 mg/dl (children <10 years) or ≥130 mg/dl (children ≥10 years). A multivariate logistic regression analysis was used to estimate the association between MUO phenotype and non-traditional cardiovascular risk factors. Results: The prevalence of the MUO status was high (61%). MUO subjects were more often male, older and pubertal (p < 0.001). The levels of the three non-traditional risk factors were significantly higher in MUO children compared to Mho children (p < 0.001) and all of them were independent predictors of the fact of being MUO [OR 1.41 (95% CI 1.24-1.69); 1.15 (95% CI 1.06-1.23) and 1.03 (95% CI1.01-1.05) for Uric Acid, HOMA index and W-Hr, respectively]. About 15% of Mho subjects had serum Uric Acid, HOMA index and W-Hr values within the highest quartile of the study population. Conclusion: The prevalence of MUO subjects in a large pediatric population is high and serum Uric Acid, HOMA index and W-Hr values are independent predictors of the probability of being MUO. A non-negligible percentage of subjects Mho has high values of all three non-traditional risk factors.
