Evaluation des pratiques d'essaimage dans le contexte de la responsabilité sociétale de l'entreprise - L'expérience de la STEG dans le secteur public tunisien
International audienceDepuis la promulgation en 2005, de la loi portant sur l'essaimage des entreprises économiques en Tunisie et la signature en 2006 de la charte d'essaimage, quelques grandes entreprises publiques, comme la Société Tunisienne de l'Electricité et du Gaz (STEG)*, ont été choisies en tant qu'entreprises pilotes pour développer cette pratique. La problématique est de savoir quels sont les facteurs de réussite de la pratique de l'essaimage dans le secteur public tunisien en prenant comme référence le cas de la STEG. L'objectif de cette recherche est d'évaluer la pertinence et la performance de cette pratique auprès des porteurs de projets essaimés. Une grille d'analyse et un modèle de recherche sont proposés à l'issue d'une revue de littérature enrichie par l'expertise professionnelle de l'auteur en tant qu'ancien directeur de la Structure d'essaimage de la STEG. La littérature sur l'essaimage est peu abondante mais elle permet de clarifier les concepts et de s'appuyer sur une typologie des pratiques (Daval, 2000 ; Brenet, 2000 ; Laviolette, 2005 ; Gauthier, Berger-Douce, 2013). La grille d'analyse et le modèle de recherche sont confrontés à une étude confirmatoire basée sur un questionnaire administré à 30 entreprises essaimées par la STEG. Les résultats montrent l'importance de la formation en phase pré-création sur la réussite d'un projet essaimé et débouchent aussi sur les principales améliorations qui doivent se faire au niveau du contrôle et suivi, de la coopération essaimé/société essaimante et au niveau de la mise à disposition des moyens financiers et communicationnels

Zeitoun Ennwader: Un nouveau cultivar d’olive à huile en Tunisie à bonne qualité d’huile et à alternance de production faible
The most outstanding olive oil cultivar ‘Chemlali Sfax’ has low oleic acid level and high palmitic acid content and a tendency to biennial bearing. Cross breeding program of this cultivar was undertaken in Tunisia since 1994 using local and foreign cultivars. Selected hybrids were planted in a comparative trial since 2005. This study aim to characterize a new olive cultivar 'Zeitoun Ennwader' better than the original cultivar. Data on morphologic, agronomic and oil quality were recorded for the new cultivar. This cultivar is distinguishable from the original cultivar due to its morphological parameters of the fruit (shape, symmetry and apex) and the endocarp (symmetry, position of maximum transverse diameter and apex). This cultivar is different from the original variety on the agronomic plan by its low alternate bearing, its early bearing and its moderate sensitivity to verticillium. The oil of the new cultivar is different from the original variety by its better fatty acid composition (higher oleic acid content and lower palmitic acid content). The adoption of this cultivar will be of great benefit to farmers (high and more regular production) and to exporters (high oil quality).

Ce cultivar se distingue du cultivar original par ses paramètres morphologiques du fruit (forme, symétrie et Apex) et de l'endocarpe (symétrie, position du diamètre transversal maximal et apex). Ce cultivar est différent de la variété originale sur le plan agronomique par sa faible indice d’alternance, son entrée précoce en production et sa sensibilité modérée au Verticillium. L'huile du nouveau cultivar est différente de la variété originale par sa meilleure composition en acides gras (teneur plus élevée en acide oléique et plus faible en acide palmitique). L’adoption de ce cultivar sera d’un grand intérêt pour les agriculteurs (production élevée et plus régulière) et pour les exportateurs (huile de bonne qualité).

Burden of obesity in the Eastern Mediterranean Region: findings from the Global Burden of Disease 2015 study
Mokdad AH, El Bcheraoui C, Afshin A, et al. Burden of obesity in the Eastern Mediterranean Region: findings from the Global Burden of Disease 2015 study. INTERNATIONAL JOURNAL OF PUBLIC HEALTH. 2018;63(Suppl. 1):165-176.We used the Global Burden of Disease (GBD) 2015 study results to explore the burden of high body mass index (BMI) in the Eastern Mediterranean Region (EMR). We estimated the prevalence of overweight and obesity among children (2-19 years) and adults (20 years) in 1980 and 2015. The burden of disease related to high BMI was calculated using the GBD comparative risk assessment approach. The prevalence of obesity increased for adults from 15.1% (95% UI 13.4-16.9) in 1980 to 20.7% (95% UI 18.8-22.8) in 2015. It increased from 4.1% (95% UI 2.9-5.5) to 4.9% (95% UI 3.6-6.4) for the same period among children. In 2015, there were 417,115 deaths and 14,448,548 disability-adjusted life years (DALYs) attributable to high BMI in EMR, which constitute about 10 and 6.3% of total deaths and DALYs, respectively, for all ages. This is the first study to estimate trends in obesity burden for the EMR from 1980 to 2015. We call for EMR countries to invest more resources in prevention and health promotion efforts to reduce this burden
Burden of cardiovascular diseases in the Eastern Mediterranean Region, 1990-2015 : findings from the Global Burden of Disease 2015 study
To report the burden of cardiovascular diseases (CVD) in the Eastern Mediterranean Region (EMR) during 1990-2015. We used the 2015 Global Burden of Disease study for estimates of mortality and disability-adjusted life years (DALYs) of different CVD in 22 countries of EMR. A total of 1.4 million CVD deaths (95% UI: 1.3-1.5) occurred in 2015 in the EMR, with the highest number of deaths in Pakistan (465,116) and the lowest number of deaths in Qatar (723). The age-standardized DALY rate per 100,000 decreased from 10,080 in 1990 to 8606 in 2015 (14.6% decrease). Afghanistan had the highest age-standardized DALY rate of CVD in both 1990 and 2015. Kuwait and Qatar had the lowest age-standardized DALY rates of CVD in 1990 and 2015, respectively. High blood pressure, high total cholesterol, and high body mass index were the leading risk factors for CVD. The age-standardized DALY rates in the EMR are considerably higher than the global average. These findings call for a comprehensive approach to prevent and control the burden of CVD in the region.Peer reviewe
Spatial, temporal, and demographic patterns in prevalence of chewing tobacco use in 204 countries and territories, 1990-2019 : a systematic analysis from the Global Burden of Disease Study 2019
Interpretation Chewing tobacco remains a substantial public health problem in several regions of the world, and predominantly in south Asia. We found little change in the prevalence of chewing tobacco use between 1990 and 2019, and that control efforts have had much larger effects on the prevalence of smoking tobacco use than on chewing tobacco use in some countries. Mitigating the health effects of chewing tobacco requires stronger regulations and policies that specifically target use of chewing tobacco, especially in countries with high prevalence. Findings In 2019, 273 center dot 9 million (95% uncertainty interval 258 center dot 5 to 290 center dot 9) people aged 15 years and older used chewing tobacco, and the global age-standardised prevalence of chewing tobacco use was 4 center dot 72% (4 center dot 46 to 5 center dot 01). 228 center dot 2 million (213 center dot 6 to 244 center dot 7; 83 center dot 29% [82 center dot 15 to 84 center dot 42]) chewing tobacco users lived in the south Asia region. Prevalence among young people aged 15-19 years was over 10% in seven locations in 2019. Although global agestandardised prevalence of smoking tobacco use decreased significantly between 1990 and 2019 (annualised rate of change: -1 center dot 21% [-1 center dot 26 to -1 center dot 16]), similar progress was not observed for chewing tobacco (0 center dot 46% [0 center dot 13 to 0 center dot 79]). Among the 12 highest prevalence countries (Bangladesh, Bhutan, Cambodia, India, Madagascar, Marshall Islands, Myanmar, Nepal, Pakistan, Palau, Sri Lanka, and Yemen), only Yemen had a significant decrease in the prevalence of chewing tobacco use, which was among males between 1990 and 2019 (-0 center dot 94% [-1 center dot 72 to -0 center dot 14]), compared with nine of 12 countries that had significant decreases in the prevalence of smoking tobacco. Among females, none of these 12 countries had significant decreases in prevalence of chewing tobacco use, whereas seven of 12 countries had a significant decrease in the prevalence of tobacco smoking use for the period. Summary Background Chewing tobacco and other types of smokeless tobacco use have had less attention from the global health community than smoked tobacco use. However, the practice is popular in many parts of the world and has been linked to several adverse health outcomes. Understanding trends in prevalence with age, over time, and by location and sex is important for policy setting and in relation to monitoring and assessing commitment to the WHO Framework Convention on Tobacco Control. Methods We estimated prevalence of chewing tobacco use as part of the Global Burden of Diseases, Injuries, and Risk Factors Study 2019 using a modelling strategy that used information on multiple types of smokeless tobacco products. We generated a time series of prevalence of chewing tobacco use among individuals aged 15 years and older from 1990 to 2019 in 204 countries and territories, including age-sex specific estimates. We also compared these trends to those of smoked tobacco over the same time period. Findings In 2019, 273 & middot;9 million (95% uncertainty interval 258 & middot;5 to 290 & middot;9) people aged 15 years and older used chewing tobacco, and the global age-standardised prevalence of chewing tobacco use was 4 & middot;72% (4 & middot;46 to 5 & middot;01). 228 & middot;2 million (213 & middot;6 to 244 & middot;7; 83 & middot;29% [82 & middot;15 to 84 & middot;42]) chewing tobacco users lived in the south Asia region. Prevalence among young people aged 15-19 years was over 10% in seven locations in 2019. Although global age standardised prevalence of smoking tobacco use decreased significantly between 1990 and 2019 (annualised rate of change: -1 & middot;21% [-1 & middot;26 to -1 & middot;16]), similar progress was not observed for chewing tobacco (0 & middot;46% [0 & middot;13 to 0 & middot;79]).

Spatial, temporal, and demographic patterns in prevalence of smoking tobacco use and attributable disease burden in 204 countries and territories, 1990-2019 : a systematic analysis from the Global Burden of Disease Study 2019
Background Ending the global tobacco epidemic is a defining challenge in global health. Timely and comprehensive estimates of the prevalence of smoking tobacco use and attributable disease burden are needed to guide tobacco control efforts nationally and globally. Methods We estimated the prevalence of smoking tobacco use and attributable disease burden for 204 countries and territories, by age and sex, from 1990 to 2019 as part of the Global Burden of Diseases, Injuries, and Risk Factors Study. We modelled multiple smoking-related indicators from 3625 nationally representative surveys. We completed systematic reviews and did Bayesian meta-regressions for 36 causally linked health outcomes to estimate non-linear dose-response risk curves for current and former smokers. We used a direct estimation approach to estimate attributable burden, providing more comprehensive estimates of the health effects of smoking than previously available. Findings Globally in 2019, 1.14 billion (95% uncertainty interval 1.13-1.16) individuals were current smokers, who consumed 7.41 trillion (7.11-7.74) cigarette-equivalents of tobacco in 2019. Although prevalence of smoking had decreased significantly since 1990 among both males (27.5% [26. 5-28.5] reduction) and females (37.7% [35.4-39.9] reduction) aged 15 years and older, population growth has led to a significant increase in the total number of smokers from 0.99 billion (0.98-1.00) in 1990. Globally in 2019, smoking tobacco use accounted for 7.69 million (7.16-8.20) deaths and 200 million (185-214) disability-adjusted life-years, and was the leading risk factor for death among males (20.2% [19.3-21.1] of male deaths). 6.68 million [86.9%] of 7.69 million deaths attributable to smoking tobacco use were among current smokers. Interpretation In the absence of intervention, the annual toll of 7.69 million deaths and 200 million disability-adjusted life-years attributable to smoking will increase over the coming decades. Substantial progress in reducing the prevalence of smoking tobacco use has been observed in countries from all regions and at all stages of development, but a large implementation gap remains for tobacco control. Countries have a dear and urgent opportunity to pass strong, evidence-based policies to accelerate reductions in the prevalence of smoking and reap massive health benefits for their citizens.
