The impact of forced displacement: trauma, increased levels of inflammation and early presentation of diabetes in women Syrian refugees.

BACKGROUND: Forced displacement and war trauma cause high rates of post-traumatic stress, anxiety disorders and depression in refugee populations. We investigated the impact of forced displacement on mental health status, gender, presentation of type 2 diabetes (T2D) and associated inflammatory markers among Syrian refugees in Lebanon. METHODS: Mental health status was assessed using the Harvard Trauma Questionnaire (HTQ) and the Hopkins Symptom Checklist-25 (HSCL-25). Additional metabolic and inflammatory markers were analyzed. RESULTS: Although symptomatic stress scores were observed in both men and women, women consistently displayed higher symptomatic anxiety/depression scores with the HSCL-25 (2.13 ± 0.58 versus 1.95 ± 0.63). With the HTQ, however, only women aged 35-55 years displayed symptomatic post-traumatic stress disorder (PTSD) scores (2.18 ± 0.43). Furthermore, a significantly higher prevalence of obesity, prediabetes and undiagnosed T2D were observed in women participants (23.43, 14.91 and 15.18%, respectively). Significantly high levels of the inflammatory marker serum amyloid A were observed in women (11.90 ± 11.27 versus 9.28 ± 6.93, P = 0.036). CONCLUSIONS: Symptomatic PTSD, anxiety/depression coupled with higher levels of inflammatory marker and T2D were found in refugee women aged between 35 and 55 years favoring the strong need for psychosocial therapeutic interventions in moderating stress-related immune dysfunction and development of diabetes in this subset of female Syrian refugees.

Assessing the governance of the health policy-making process using a new governance tool: the case of Lebanon.

BACKGROUND: In the international agenda, it has become common to assert that the assessment of health system governance using a practical tool is crucial. This approach can help us better understand how health systems are being steered as well as to identify gaps in the decision-making process and their causes. The authors developed a new assessment tool, the Health Policymaking Governance Guidance Tool (HP-GGT), that was designed to be conceptually sound and practical. This tool enables policy-makers and stakeholders to systematically review and assess health system governance at policy-making level. This article presents first use of the HP-GGT in Lebanon, together with generated results, recommendations, and discusses how these results improve governance practices when initiating new health policy formulation processes. METHODS: The HP-GGT, which is a multidimensional structured tool, was used retrospectively to assess and review the process used to develop a new mental health strategy; this process was compared against consensus-based good governance principles, focusing on participation, transparency, accountability, information and responsiveness. The assessment was conducted through face-to-face interviews with 11 key informants who were involved in the development of the strategy. RESULTS: The HP-GGT enabled policy-makers to reflect on their governance practices when developing a mental health strategy and was able to identify key areas of strengths and weaknesses using good governance practice checklists given by the questions. The insights generated from the assessment equipped the national policy-makers with a better understanding of the practice and meaning of policy-making governance. Identifying weaknesses to be addressed in future attempts to develop other national health policies helped in this regard. Using the tool also increased awareness of alternative good practices among policy-makers and stakeholders. CONCLUSIONS: Assessing a health policy formulation process from a governance perspective is essential for improved policy-making. The HP-GGT was able to provide a general overview and an in-depth assessment of a policy formulation process related to governance issues according to international good practices that should be applied while formulating health policies in any field. The HP-GGT was found to be a practical tool that was useful for policy-makers when used in Lebanon and awaits applications in other low- and middle-income countries to further show its validity and utility.

Vaccination coverage in Lebanon following the Syrian crisis: results from the district-based immunization coverage evaluation survey 2016.

BACKGROUND: Following the Syrian crisis, a substantial influx of Syrian refugees into Lebanon posed new challenges to optimal vaccination coverage for all children residing in the country. In 2016, the district-based immunization coverage evaluation survey (CES) assessed routine immunization coverage at the district level in Lebanon among children aged 12-59 months. METHODS: A cross-sectional multistage cluster survey was conducted in all of Lebanon (with the exception of the Nabatieh district) using the World Health Organization (WHO) recommended Expanded Programme on Immunization (EPI) methodology adapted to the local context. A survey questionnaire consisting of closed and open-ended questions concerning demographic information and the child's immunization status was administered to collect immunization status information. RESULTS: Among surveyed children aged 12-59 months, irrespective of nationality, vaccination coverage at the national level for any recommended last dose was below the targeted 95%. Generally, vaccination coverage levels increased with age and were higher among Lebanese than Syrian children. However, large variations were revealed when coverage rates were analyzed at the district level. Vaccination was significantly associated with nationality, age, mother's educational status and the place of vaccination. Common reasons for undervaccination included the child's illness at the time of vaccine administration, vaccination fees, lack of awareness or a doctor's advice not to vaccinate during campaigns. CONCLUSIONS: Substantial variability exists in vaccination coverage among children aged 12-59 months residing in different districts in Lebanon. Immunization coverage reached 90% or above only for the first doses of polio and pentavalent vaccines. A considerable dropout rate from the first dose of any vaccine is observed. Efforts to optimize coverage levels should include increased vaccination initiatives targeting both refugee children and children from vulnerable host communities, increased cooperation between public and private vaccine providers, improved training for vaccine providers to adhere to complete vaccine administration recommendations, and increased awareness among caregivers.

PulseNet Lebanon: An Overview of Its Activities, Outbreak Investigations, and Challenges.

Background: Foodborne diseases are still a major health issue in Lebanon, although some steps have been taken forward in food safety. To this purpose, PulseNet Lebanon, a foodborne diseases tracking network, was established in 2009, through the collaboration between the Ministry of Public Health (MoPH) and the American University of Beirut (AUB). Materials and Methods: Three papers published regarding the PulseNet project were summarized. Initially, clinical and food samples, collected within the surveillance network scope, were identified by using the respective API for Salmonella and Listeria spp. Salmonella spp. were further serotyped by using the Kauffman and White method. Campylobacter spp. were determined by the 16 S rRNA sequencing method. Antimicrobial susceptibility to a number of antibiotics was determined by using the disk diffusion method for Samonella and Campylobacter spp. Genomic diversity was determined by using pulsed field gel electrophoresis (PFGE) and random amplified polymorphic DNA (RAPD). Results: Results indicated that 290 clinical and 49 food isolates were identified as Salmonella. Serotyping revealed the prevalence of ten and seven serotypes in the clinical and food samples, respectively. Fifty-one isolates from chicken ceca and carcass were identified to be Campylobacter spp. Fifty-nine samples were identified to be Listeria monocytogenes. Antimicrobial susceptibility testing revealed a wide range of resistance among the different samples. PFGE showed a variation in pulsotypes among the Salmonella serotypes. PFGE also linked certain outbreaks to their food sources. This method also demonstrated 13 subtypes with 100% similarity among the L. monocytogenes isolates. Finally, the Camplyobcater spp. were grouped into nine clusters with a minimum similarity of 43.5% using RAPD. Conclusion: This summary of results shows the importance of implementing a "farm-to-fork" approach in the surveillance of foodborne disease outbreaks in Lebanon, allowing the detection of pathogens causing foodborne disease outbreaks in a timely fashion.

Containment of Highly Pathogenic Avian Influenza A(H5N1) Virus, Lebanon, 20161.

A preparedness plan for avian influenza A(H5N1) virus infection was activated in Lebanon in 2016 after reported cases in poultry. Exposed persons were given prophylaxis and monitored daily. A total of 185 exposed persons were identified: 180 received prophylaxis, 181 were monitored, and 41 suspected cases were reported. All collected specimens were negative for virus by PCR.

mHealth use for non-communicable diseases care in primary health: patients' perspective from rural settings and refugee camps.

Background: Non-communicable diseases (NCDs) account for 85% of deaths in Lebanon and contribute to remarkable morbidity and mortality among refugees and underserved populations. This study assesses the perspectives of individuals with hypertension and/or diabetes in rural areas and Palestinian refugee camps towards a population based mHealth intervention called 'eSahha'. Methods: The study employs a mixed-methods design to evaluate the effectiveness of SMSs on self-reported perceptions of lifestyle modifications. Quantitative data was collected through phone surveys, and qualitative data through focus group discussions. Descriptive statistics and bivariate analysis were performed. Results: About 93.9% (n = 1000) of respondents perceived the SMSs as useful and easy to read and understand. About 76.9% reported compliance with SMSs through daily behavioral modifications. Women (P = 0.007), people aged ≥76 years (P < 0.001), unemployed individuals (P < 0.001), individuals who only read and write (P < 0.001) or those who are illiterate (P < 0.001) were significantly more likely to receive and not read the SMSs. Behavior change across settings was statistically significant (P < 0.001). Conclusion: While SMS-based interventions targeting individuals with hypertension and/or diabetes were generally satisfactory among those living in rural areas and Palestinian refugee camps in Lebanon, a more tailored approach for older, illiterate and unemployed individuals is needed.

Association of waterpipe smoking with myocardial infarction and determinants of metabolic syndrome among catheterized patients.

BACKGROUND: Waterpipe smoking is a rising global public health epidemic perceived by many users to be less harmful, though its toxicity overlaps or even exceeds that of cigarette smoking. Short-term cardiovascular changes due to waterpipe smoking are well established, but longer-term health impacts are still not fully elucidated. OBJECTIVE: We aim to investigate the association of waterpipe smoking with myocardial infarction among patients undergoing cardiac catheterization. METHODS: The study was performed on Lebanese patients referred for cardiac catheterization. Patient's blood was collected for metabolic measures and questionnaires were filled out to include socio-demographic, behavioral and pertinent medical characteristics of the study subjects. RESULTS: Myocardial infarction is significantly and independently associated with waterpipe smoking, with odds ratio (OR) of 1.329 (95% CI: [1.04-1.68]; p = .021), which is lower than that for cigarette smoking (OR = 1.87, 95% CI: [1.63-2.15]; p < .001). Only diabetes showed significant association with waterpipe smoking among MI enrollees (OR = 1.66, 95%CI: [1.04-2.63]; p = .032). CONCLUSION: The study provides yet another evidence for the adverse cardiovascular effects of waterpipe smoking on a clinical level. The harmful effects of waterpipe smoking should be underscored by health care professionals.

Developing an interministerial substance use response strategy for Lebanon: process, content and lessons learned.

Evidence on substance use in Lebanon shows an increase in usage, limited availability and accessibility to evidence-based services, and high level of stigma and discrimination. In line with the "Mental Health and Substance Use Strategy for Lebanon 2015-2020", the Ministry of Public Health initiated the process of developing a strategy focused on substance use response to address these challenges in collaboration with the Ministries of Education and Higher Education, Interior and Municipalities, Justice and Social Affairs. The result of this process was a strategy launched jointly by the ministries including six domains of action covering the whole spectrum of substance use response with strategic objectives addressing the challenges identified through stakeholders' consultations. The following key principles adopted throughout the process contributed to the successful development of the strategy: building on evidence and international frameworks, maximizing the participation of all stakeholders, prioritising national consensus, maintaining flexibility and maximizing transparency.

Lebanon's experience in surveillance of communicable diseases during a mass gathering: Sixth Francophone Games, 2009.

In 2009, Lebanon hosted the 6th Francophone Games. Pandemic A(H1N1)2009 virus presented significant health threat at the time. A surveillance strategy was implemented for the timely detection and management of epidemiological events and outbreaks, in particular for A(H1N1)2009 virus cases. Data were collected and managed daily and feedback was generated through daily bulletins. A total of 299 medical consultations were reported, 29% of which related to infectious diseases. There were 10 cases reported as acute respiratory infections; all tested negative for A(H1N1)2009 virus within 24 hours. Twenty-three cases of gastroenteritis were reported, for which 11 stool cultures were negative. While pandemic A(H1N1)2009 did not interfere with the Games, it was essential to strengthen surveillance and to have timely epidemiological information. This was achieved through preparedness, a multi-disciplinary approach, timely management and coordination.

Global, regional, and national disability-adjusted life years (DALYs) for 306 diseases and injuries and healthy life expectancy (HALE) for 188 countries, 1990-2013: quantifying the epidemiological transition.

BACKGROUND: The Global Burden of Disease Study 2013 (GBD 2013) aims to bring together all available epidemiological data using a coherent measurement framework, standardised estimation methods, and transparent data sources to enable comparisons of health loss over time and across causes, age-sex groups, and countries. The GBD can be used to generate summary measures such as disability-adjusted life-years (DALYs) and healthy life expectancy (HALE) that make possible comparative assessments of broad epidemiological patterns across countries and time. These summary measures can also be used to quantify the component of variation in epidemiology that is related to sociodemographic development. METHODS: We used the published GBD 2013 data for age-specific mortality, years of life lost due to premature mortality (YLLs), and years lived with disability (YLDs) to calculate DALYs and HALE for 1990, 1995, 2000, 2005, 2010, and 2013 for 188 countries. We calculated HALE using the Sullivan method; 95% uncertainty intervals (UIs) represent uncertainty in age-specific death rates and YLDs per person for each country, age, sex, and year. We estimated DALYs for 306 causes for each country as the sum of YLLs and YLDs; 95% UIs represent uncertainty in YLL and YLD rates. We quantified patterns of the epidemiological transition with a composite indicator of sociodemographic status, which we constructed from income per person, average years of schooling after age 15 years, and the total fertility rate and mean age of the population. We applied hierarchical regression to DALY rates by cause across countries to decompose variance related to the sociodemographic status variable, country, and time. FINDINGS: Worldwide, from 1990 to 2013, life expectancy at birth rose by 6·2 years (95% UI 5·6-6·6), from 65·3 years (65·0-65·6) in 1990 to 71·5 years (71·0-71·9) in 2013, HALE at birth rose by 5·4 years (4·9-5·8), from 56·9 years (54·5-59·1) to 62·3 years (59·7-64·8), total DALYs fell by 3·6% (0·3-7·4), and age-standardised DALY rates per 100 000 people fell by 26·7% (24·6-29·1). For communicable, maternal, neonatal, and nutritional disorders, global DALY numbers, crude rates, and age-standardised rates have all declined between 1990 and 2013, whereas for non-communicable diseases, global DALYs have been increasing, DALY rates have remained nearly constant, and age-standardised DALY rates declined during the same period. From 2005 to 2013, the number of DALYs increased for most specific non-communicable diseases, including cardiovascular diseases and neoplasms, in addition to dengue, food-borne trematodes, and leishmaniasis; DALYs decreased for nearly all other causes. By 2013, the five leading causes of DALYs were ischaemic heart disease, lower respiratory infections, cerebrovascular disease, low back and neck pain, and road injuries. Sociodemographic status explained more than 50% of the variance between countries and over time for diarrhoea, lower respiratory infections, and other common infectious diseases; maternal disorders; neonatal disorders; nutritional deficiencies; other communicable, maternal, neonatal, and nutritional diseases; musculoskeletal disorders; and other non-communicable diseases. However, sociodemographic status explained less than 10% of the variance in DALY rates for cardiovascular diseases; chronic respiratory diseases; cirrhosis; diabetes, urogenital, blood, and endocrine diseases; unintentional injuries; and self-harm and interpersonal violence. Predictably, increased sociodemographic status was associated with a shift in burden from YLLs to YLDs, driven by declines in YLLs and increases in YLDs from musculoskeletal disorders, neurological disorders, and mental and substance use disorders. In most country-specific estimates, the increase in life expectancy was greater than that in HALE. Leading causes of DALYs are highly variable across countries. INTERPRETATION: Global health is improving. Population growth and ageing have driven up numbers of DALYs, but crude rates have remained relatively constant, showing that progress in health does not mean fewer demands on health systems. The notion of an epidemiological transition--in which increasing sociodemographic status brings structured change in disease burden--is useful, but there is tremendous variation in burden of disease that is not associated with sociodemographic status. This further underscores the need for country-specific assessments of DALYs and HALE to appropriately inform health policy decisions and attendant actions. FUNDING: Bill & Melinda Gates Foundation.

The global burden of injury: incidence, mortality, disability-adjusted life years and time trends from the Global Burden of Disease study 2013.

BACKGROUND: The Global Burden of Diseases (GBD), Injuries, and Risk Factors study used the disability-adjusted life year (DALY) to quantify the burden of diseases, injuries, and risk factors. This paper provides an overview of injury estimates from the 2013 update of GBD, with detailed information on incidence, mortality, DALYs and rates of change from 1990 to 2013 for 26 causes of injury, globally, by region and by country. METHODS: Injury mortality was estimated using the extensive GBD mortality database, corrections for ill-defined cause of death and the cause of death ensemble modelling tool. Morbidity estimation was based on inpatient and outpatient data sets, 26 cause-of-injury and 47 nature-of-injury categories, and seven follow-up studies with patient-reported long-term outcome measures. RESULTS: In 2013, 973 million (uncertainty interval (UI) 942 to 993) people sustained injuries that warranted some type of healthcare and 4.8 million (UI 4.5 to 5.1) people died from injuries. Between 1990 and 2013 the global age-standardised injury DALY rate decreased by 31% (UI 26% to 35%). The rate of decline in DALY rates was significant for 22 cause-of-injury categories, including all the major injuries. CONCLUSIONS: Injuries continue to be an important cause of morbidity and mortality in the developed and developing world. The decline in rates for almost all injuries is so prominent that it warrants a general statement that the world is becoming a safer place to live in. However, the patterns vary widely by cause, age, sex, region and time and there are still large improvements that need to be made.

Strategic assessment of implementation of neonatal resuscitation training at a national level.

BACKGROUND: Structuring and implementation of an endorsed neonatal resuscitation program (NRP) results in decreased neonatal mortality. This study evaluated the implementation of formal training using the NRP in a private sector context of a middle income country. METHODS: Between 2008 and 2011, the National Collaborative Perinatal Neonatal Network (NCPNN) supported by the Ministry of Health piloted the implementation of NRP training in member hospitals throughout the country. Training of trainers (TOT) then providers (TOP) took place via workshops where a lecture was given followed by hands-on training using low-fidelity manikins. Pre- and post-workshop knowledge assessment and hands-on training evaluation were done. t-test and one-way ANOVA were used to compare mean differences in pre- and post-workshop scores and percent improvement across specialties and locations. RESULTS: Of 20 TOT participants, nine (45%) conducted NRP in their hospitals. Ten TOP workshops included 256 professionals. The majority were doctors (128, 50%), followed by nurses (99, 39%) and midwives (20, 8%). Overall pre-training scores (67.25 ± 16.00%) were significantly lower than post-training scores (87.48 ± 11.89%; P = 0.000); percent improvement among all participants was 37.12 ± 41.15%; P = 0.82). Nurses and participants from the northern governorate had highest mean difference in before/after scores (21.56 ± 12.32 and 23.29 ± 6.62, respectively). Midwives had the highest percent improvement (40.44 ± 47.28). All but 25 participants (9.8%) passed the megacode at the first attempt. CONCLUSIONS: Implementing NRP training is essential to increase the knowledge and skills of health-care professionals. It is sustainable with support from the Ministry and other sources. Continuing education should be mandated at the Ministry of Health level.

Global, regional, and national levels of neonatal, infant, and under-5 mortality during 1990-2013: a systematic analysis for the Global Burden of Disease Study 2013.

BACKGROUND: Remarkable financial and political efforts have been focused on the reduction of child mortality during the past few decades. Timely measurements of levels and trends in under-5 mortality are important to assess progress towards the Millennium Development Goal 4 (MDG 4) target of reduction of child mortality by two thirds from 1990 to 2015, and to identify models of success. METHODS: We generated updated estimates of child mortality in early neonatal (age 0-6 days), late neonatal (7-28 days), postneonatal (29-364 days), childhood (1-4 years), and under-5 (0-4 years) age groups for 188 countries from 1970 to 2013, with more than 29,000 survey, census, vital registration, and sample registration datapoints. We used Gaussian process regression with adjustments for bias and non-sampling error to synthesise the data for under-5 mortality for each country, and a separate model to estimate mortality for more detailed age groups. We used explanatory mixed effects regression models to assess the association between under-5 mortality and income per person, maternal education, HIV child death rates, secular shifts, and other factors. To quantify the contribution of these different factors and birth numbers to the change in numbers of deaths in under-5 age groups from 1990 to 2013, we used Shapley decomposition. We used estimated rates of change between 2000 and 2013 to construct under-5 mortality rate scenarios out to 2030. FINDINGS: We estimated that 6·3 million (95% UI 6·0-6·6) children under-5 died in 2013, a 64% reduction from 17·6 million (17·1-18·1) in 1970. In 2013, child mortality rates ranged from 152·5 per 1000 livebirths (130·6-177·4) in Guinea-Bissau to 2·3 (1·8-2·9) per 1000 in Singapore. The annualised rates of change from 1990 to 2013 ranged from -6·8% to 0·1%. 99 of 188 countries, including 43 of 48 countries in sub-Saharan Africa, had faster decreases in child mortality during 2000-13 than during 1990-2000. In 2013, neonatal deaths accounted for 41·6% of under-5 deaths compared with 37·4% in 1990. Compared with 1990, in 2013, rising numbers of births, especially in sub-Saharan Africa, led to 1·4 million more child deaths, and rising income per person and maternal education led to 0·9 million and 2·2 million fewer deaths, respectively. Changes in secular trends led to 4·2 million fewer deaths. Unexplained factors accounted for only -1% of the change in child deaths. In 30 developing countries, decreases since 2000 have been faster than predicted attributable to income, education, and secular shift alone. INTERPRETATION: Only 27 developing countries are expected to achieve MDG 4. Decreases since 2000 in under-5 mortality rates are accelerating in many developing countries, especially in sub-Saharan Africa. The Millennium Declaration and increased development assistance for health might have been a factor in faster decreases in some developing countries. Without further accelerated progress, many countries in west and central Africa will still have high levels of under-5 mortality in 2030.

Global, regional, and national levels and causes of maternal mortality during 1990-2013: a systematic analysis for the Global Burden of Disease Study 2013.

BACKGROUND: The fifth Millennium Development Goal (MDG 5) established the goal of a 75% reduction in the maternal mortality ratio (MMR; number of maternal deaths per 100,000 livebirths) between 1990 and 2015. We aimed to measure levels and track trends in maternal mortality, the key causes contributing to maternal death, and timing of maternal death with respect to delivery. METHODS: We used robust statistical methods including the Cause of Death Ensemble model (CODEm) to analyse a database of data for 7065 site-years and estimate the number of maternal deaths from all causes in 188 countries between 1990 and 2013. We estimated the number of pregnancy-related deaths caused by HIV on the basis of a systematic review of the relative risk of dying during pregnancy for HIV-positive women compared with HIV-negative women. We also estimated the fraction of these deaths aggravated by pregnancy on the basis of a systematic review. To estimate the numbers of maternal deaths due to nine different causes, we identified 61 sources from a systematic review and 943 site-years of vital registration data. We also did a systematic review of reports about the timing of maternal death, identifying 142 sources to use in our analysis. We developed estimates for each country for 1990-2013 using Bayesian meta-regression. We estimated 95% uncertainty intervals (UIs) for all values. FINDINGS: 292,982 (95% UI 261,017-327,792) maternal deaths occurred in 2013, compared with 376,034 (343,483-407,574) in 1990. The global annual rate of change in the MMR was -0·3% (-1·1 to 0·6) from 1990 to 2003, and -2·7% (-3·9 to -1·5) from 2003 to 2013, with evidence of continued acceleration. MMRs reduced consistently in south, east, and southeast Asia between 1990 and 2013, but maternal deaths increased in much of sub-Saharan Africa during the 1990s. 2070 (1290-2866) maternal deaths were related to HIV in 2013, 0·4% (0·2-0·6) of the global total. MMR was highest in the oldest age groups in both 1990 and 2013. In 2013, most deaths occurred intrapartum or postpartum. Causes varied by region and between 1990 and 2013. We recorded substantial variation in the MMR by country in 2013, from 956·8 (685·1-1262·8) in South Sudan to 2·4 (1·6-3·6) in Iceland. INTERPRETATION: Global rates of change suggest that only 16 countries will achieve the MDG 5 target by 2015. Accelerated reductions since the Millennium Declaration in 2000 coincide with increased development assistance for maternal, newborn, and child health. Setting of targets and associated interventions for after 2015 will need careful consideration of regions that are making slow progress, such as west and central Africa.

Global, regional, and national prevalence of overweight and obesity in children and adults during 1980-2013: a systematic analysis for the Global Burden of Disease Study 2013.

BACKGROUND: In 2010, overweight and obesity were estimated to cause 3·4 million deaths, 3·9% of years of life lost, and 3·8% of disability-adjusted life-years (DALYs) worldwide. The rise in obesity has led to widespread calls for regular monitoring of changes in overweight and obesity prevalence in all populations. Comparable, up-to-date information about levels and trends is essential to quantify population health effects and to prompt decision makers to prioritise action. We estimate the global, regional, and national prevalence of overweight and obesity in children and adults during 1980-2013. METHODS: We systematically identified surveys, reports, and published studies (n=1769) that included data for height and weight, both through physical measurements and self-reports. We used mixed effects linear regression to correct for bias in self-reports. We obtained data for prevalence of obesity and overweight by age, sex, country, and year (n=19,244) with a spatiotemporal Gaussian process regression model to estimate prevalence with 95% uncertainty intervals (UIs). FINDINGS: Worldwide, the proportion of adults with a body-mass index (BMI) of 25 kg/m(2) or greater increased between 1980 and 2013 from 28·8% (95% UI 28·4-29·3) to 36·9% (36·3-37·4) in men, and from 29·8% (29·3-30·2) to 38·0% (37·5-38·5) in women. Prevalence has increased substantially in children and adolescents in developed countries; 23·8% (22·9-24·7) of boys and 22·6% (21·7-23·6) of girls were overweight or obese in 2013. The prevalence of overweight and obesity has also increased in children and adolescents in developing countries, from 8·1% (7·7-8·6) to 12·9% (12·3-13·5) in 2013 for boys and from 8·4% (8·1-8·8) to 13·4% (13·0-13·9) in girls. In adults, estimated prevalence of obesity exceeded 50% in men in Tonga and in women in Kuwait, Kiribati, Federated States of Micronesia, Libya, Qatar, Tonga, and Samoa. Since 2006, the increase in adult obesity in developed countries has slowed down. INTERPRETATION: Because of the established health risks and substantial increases in prevalence, obesity has become a major global health challenge. Not only is obesity increasing, but no national success stories have been reported in the past 33 years. Urgent global action and leadership is needed to help countries to more effectively intervene.

Improving awareness of preconception health among adolescents: experience of a school-based intervention in Lebanon.

BACKGROUND: Maternal behavior before and after conception affects maternal and child health. Limited awareness of adolescents in preconception health may be addressed through school education. The aim of this intervention is to assess preconception health awareness among adolescents in Lebanese high schools and to test the effectiveness of a one-time educational session in improving preconception knowledge. METHODS: The intervention consisted of a 30-minute educational session about good practices in preconception health, developed by the National Collaborative Perinatal Neonatal Network's (NCPNN) research team. A convenience sample of high school Lebanese students in grades 10 to 12, aged 14 to 26 years old, from 70 private and public schools in all six Lebanese provinces, participated in the intervention in 2011 and 2012. A multiple-choice questionnaire administered prior to and 2 months after the session was used to assess knowledge improvement among the students. RESULTS: A total of 7,290 students were enrolled. After the session, mean scores of correct answers increased from 4.36 to 6.42 out of 10, representing a 47.2% improvement (p < 0.001). The percent of correct answers increased for all the questions regarding health practices (p < 0.001). The greatest improvement was observed for questions about Trisomy 21, folic acid intake and toxoplasmosis with percentages improvement of 96%, 172% and 83% respectively. Being female or in private school was a significant predictor of higher scores in both pre-test and post-test (p < 0.001). CONCLUSIONS: Awareness campaigns in schools increased the preconception health knowledge among high school students. We recommend expanding the scope of this intervention into universities in Lebanon.

Screening for cardiovascular risk in asymptomatic users of the primary health care network in Lebanon, 2012-2013.

INTRODUCTION: In 2012, the Ministry of Public Health in Lebanon piloted a service of multifactorial cardiovascular screening in the publicly subsidized Primary Health Care (PHC) Network. We present an epidemiological analysis of data produced during this pilot to justify the inclusion of this service in the package of essential services offered through PHC and to present a preliminary cardiovascular risk profile in an asymptomatic population. METHODS: A total of 4,205 participants (two-thirds of which were women) aged at least 40 years and reportedly free from diabetes, hypertension, dyslipidemia, and cardiovascular disease (CVD) were screened. The screening protocol used a questionnaire and direct measurements to assess 5 modifiable cardiovascular risk factors; total cardiovascular risk score was calculated according to a paper-based algorithm developed by the World Health Organization and the International Society of Hypertension. RESULTS: Approximately 25% of the sample displayed metabolic impairments (11% for impaired blood glucose metabolism and 17% for impaired systolic blood pressure), and 6.6% were classified at total cardiovascular risk of 10% or more. Just over one-quarter of the sample was obese, almost half had a substantially elevated waist circumference, and 41% were smokers. Men were significantly more likely to screen positive for metabolic impairment than women, and women were more likely to be obese. CONCLUSION: The implementation of a multifactorial screening for CVD among asymptomatic subjects detected a substantial proportion of previously undiagnosed cases of high metabolic risk, people who could now be referred to optimal medical follow-up.

Observations on the Ministry of Public Health program of support to the hospitalization of patients in Lebanon.

Lebanon has a highly fragmented health care system. The Lebanese population receives its health care services through a system dominated by the private sector that is dependent to a large extent on public sector financing. Lebanon spends about 83% of its Gross Domestic Product (GDP) on health. This study consists of observations on the utilization of the Ministry of Public Health (MOH) program of hospital care provision. The study population included all patients admitted for hospitalization in any of the 126 hospitals contracted with the MOH, between August 2008 and July 2009 (one full year). This review is limited to medical admissions only. The surgical admissions have been excluded since they are covered under a 'flat fee' reimbursement. Findings reveal that a significant proportion of the hospital admissions under this program are for conditions that may not need hospitalization. Moreover, most of these admissions receive care in relatively small and peripheral hospitals. The findings ought to lead to a further scrutiny of the ministry program of support to the hospitalization of its nationals. Measures may be indicated to improve the efficiency and effectiveness of hospital utilization, avoid waste and possibly fraud, and reconsider the role of small and peripheral hospitals within the health care system of the country.
