    The topic of work engagement is moving up on the managerial agenda as it sets the stage for numerous beneficial outcomes for both organizations and their employees. It is clear, however, that not all employees are equally engaged in their job. The current study taps into theory on positive self-fulfilling prophecies induced by leaders’ high expectations of followers (i.e., the Pygmalion effect) and examines their potential to facilitate follower work engagement. By integrating literature on implicit followership theories with the Pygmalion model, we investigate the assumption that leaders’ high expectations are universally perceived as and therefore foster the same desirable results for all employees. We argue and find that the extent to which followers’ work engagement benefits from high leader expectations de

    Background. To interpret cervical cancer screening model results, we need to understand the influence of model structure and assumptions on cancer incidence and mortality predictions. Cervical cancer cases and deaths following screening can be attributed to 1) (precancerous or cancerous) disease that occurred after screening, 2) disease that was present but not screen detected, or 3) disease that was screen detected but not successfully treated. We examined the relative contributions of each of these using 4 Cancer Intervention and Surveillance Modeling Network (CISNET) models. Methods. The maximum clinical incidence reduction (MCLIR) method compares changes in the number of clinically detected cervical cancers and mortality among 4 scenarios: 1) no screening, 2) one-time perfect screening at age 45 that detects all existing disease and delivers perfect (i.e., 100% effective) treatment of all screen-detected disease, 3) one-time realistic-sensitivity cytological screening and perfect treatment of all screen-detected disease, and 4) one-time realistic-sensitivity cytological screening and realistic-effectiveness treatment of all screen-detected disease. Results. Predicted incidence reductions ranged from 55% to 74%, and mortality reduction ranged from 56% to 62% within 15 years of follow-up for scenario 4 across models. The proportion of deaths due to disease not detected by screening differed across the models (21%–35%), as did the failure of treatment (8%–16%) and disease occurring after screening (from 1%–6%). Conclusions. The MCLIR approach aids in the interpretation of variability across model results. We showed that the reasons why screening failed to prevent cancers and deaths differed between the models. This likely reflects uncertainty about unobservable model inputs and structures; the impact of this uncertainty on policy conclusions should be examined via comparing findings from different well-calibrated and validated model platforms

    Repositioning of the global epicentre of non-optimal cholesterol

    High blood cholesterol is typically considered a feature of wealthy western countries1,2. However, dietary and behavioural determinants of blood cholesterol are changing rapidly throughout the world3 and countries are using lipid-lowering medications at varying rates. These changes can have distinct effects on the levels of high-density lipoprotein (HDL) cholesterol and non-HDL cholesterol, which have different effects on human health4,5. However, the trends of HDL and non-HDL cholesterol levels over time have not been previously reported in a global analysis. Here we pooled 1,127 population-based studies that measured blood lipids in 102.6 million individuals aged 18 years and older to estimate trends from 1980 to 2018 in mean total, non-HDL and HDL cholesterol levels for 200 countries. Globally, there was little change in total or non-HDL cholesterol from 1980 to 2018. This was a net effect of increases in low- and middle-income countries, especially in east and southeast Asia, and decreases in high-income western countries, especially those in northwestern Europe, and in central and eastern Europe. As a result, countries with the highest level of non-HDL cholesterol—which is a marker of cardiovascular risk—changed from those in western Europe such as Belgium, Finland, Greenland, Iceland, Norway, Sweden, Switzerland and Malta in 1980 to those in Asia and the Pacific, such as Tokelau, Malaysia, The Philippines and Thailand. In 2017, high non-HDL cholesterol was responsible for an estimated 3.9 million (95% credible interval 3.7 million–4.2 million) worldwide deaths, half of which occurred in east, southeast and south Asia. The global repositioning of lipid-related risk, with non-optimal cholesterol shifting from a distinct feature of high-income countries in northwestern Europe, north America and Australasia to one that affects countries in east and southeast Asia and Oceania should motivate the use of population-based policies and personal interventions to improve nutrition and enhance access to treatment throughout the world.</p

    A century of trends in adult human height

    No full text
    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 17.5-22.7) and 16.5 cm (13.3-19.7) 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; 135.8-144.8). 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

    Rising rural body-mass index is the main driver of the global obesity epidemic in adults

    Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities 1,2 . This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity 3�6 . Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean BMI segregated by place of residence (a rural or urban area) from 1985 to 2017. We show that, contrary to the dominant paradigm, more than 55 of the global rise in mean BMI from 1985 to 2017�and more than 80 in some low- and middle-income regions�was due to increases in BMI in rural areas. This large contribution stems from the fact that, with the exception of women in sub-Saharan Africa, BMI is increasing at the same rate or faster in rural areas than in cities in low- and middle-income regions. These trends have in turn resulted in a closing�and in some countries reversal�of the gap in BMI between urban and rural areas in low- and middle-income countries, especially for women. In high-income and industrialized countries, we noted a persistently higher rural BMI, especially for women. There is an urgent need for an integrated approach to rural nutrition that enhances financial and physical access to healthy foods, to avoid replacing the rural undernutrition disadvantage in poor countries with a more general malnutrition disadvantage that entails excessive consumption of low-quality calories. © 2019, The Author(s)

    Introduction : Ce travail avait pour objectifs d’identifier le comportement des jeunes filles apprenties face à la contraception et leur perception sur planification familiale (PF). Méthodologie : Le cadre de notre étude a été les ateliers d’apprentissages de la commune de Kpalimé. Il s’agit d’une étude&nbsp; transversale descriptive portant sur les jeunes filles apprenties qui s’était déroulée du 20 juin au 25 juillet 2019. Résultats : Cette étude a porté sur 100 filles apprenties. L’âge moyen était de 21,9 ans ± 3,8 ans ; avec des extrêmes à 13 ans et 32 ans. Selon le statut matrimonial on avait des concubins, des célibataires et des mariées respectivement à 54, 34 et 12%. Sur la définition de la planification familiale 56% affirmait ne rien connaitre. Le type de méthode contraceptive connue par les enquêtés était le préservatif ; le préservatif-l’injectable ; le préservatif- l’injectable- la pilule dans des proportions de 42 ; 24 et 21%. L’approbation de l’utilisation descontraceptives a été fait pour éviter les grossesses à 62%, pour éviter les infections à 3%, pour se protéger à 2% pour espacer les naissances à 1% et dans une proportion de 32% il n’y pas eu de réponses. Les raisons des difficultés d’accès aux services de la PF étaient la honte à 63%, pas de motif à 17%, le manque de temps à 15% et la non disponibilité des services le week-end à 5%. Conclusion : Notre étude a révélé une relative bonne connaissance des méthodes contraceptives et de planification familiale que les&nbsp; enquêtés avait du mal à mettre en pratique. Mots clés : Contraception ; planification familiale ; Fille apprenties ; Togo &nbsp; English title: Knowledge, attitudes and pratices on contraception: The case of apprentice gril from Kpalime Introduction: The aim of this work was to identify the behavior of young apprentice girls with regard to contraception and their perception of family planning (FP). Methodology: The framework of our study was the learning workshops of the municipality of Kpalimé. This is a descriptive cross-sectional study on young apprentice girls which took place from June 20 to July 25, 2019. Results: This study focused on 100 apprentice girls. The mean age was 21.9 years ± 3.8 years; with extremes at 13 and 32 years old. According to marital status, there were partners, singles and brides at 54, 34 and 12% respectively. On the definition of family planning, 56% claimed to know nothing. The type of contraceptive method known by the respondents was the condom; the injectable condom;the condom-the injectable-the pill in proportions of 42; 24 and 21%. The approval of contraceptive use was made to avoid pregnancies at 62%, to avoid infections at 3%, to protect themselves at 2% to space births at 1% and in a proportion of 32% their there were no answers. The reasons for difficulties in accessing FP services were shame at 63%, no reason at 17%, lack of time at 15% and&nbsp; unavailability of weekend services at 5%. Conclusion: Our study revealed a relatively good knowledge of contraceptive and family planning methods that the respondents had trouble putting into practice.
