Adolescents' self-perceived and actual weight: Which plays a dominant role in weight loss behaviour in Lebanon?

BACKGROUND: The decision to lose weight among adolescents is complex and is guided by a number of body-related factors. This study examined the extent of agreement between actual weight, measured as body mass index, and self-perceived weight and assessed their relative importance in weight loss behaviour among Lebanese adolescents. METHODS: Data on 278 adolescents aged 13-17 years were drawn from the nationwide Nutrition and Non-Communicable Disease Risk Factor Survey (Lebanon, 2009). Binary multivariable logistic regressions were conducted to test associations with "effort to lose weight" as the outcome variable, controlling for a number of potential confounders. RESULTS: Close to 36% reported trying to lose weight. Around 21% and 13% were overweight and obese, respectively, and 40% and 10% perceived their weight as slightly high and very high, respectively. Inaccurate perceivers, those underestimating or overestimating their weight, constituted 39%, with overall percent agreement between actual and self-perceived weight being 60.8% (kappa statistic = 0.319, 95% CI [0.242, 0.396]). About a third of the overweight adolescents (30.5%) and more than half of the obese (56.8%) underestimated their weight. In the multivariable analysis, self-perceived weight was statistically significant and a stronger predictor of weight loss effort than body mass index (adjusted odds ratios = 14.42 and 6.42 for slightly high and very high perceived weight, respectively, compared to odds ratios = 1.47 and 2.31 for overweight and obese adolescents, respectively). CONCLUSION: Health professionals need to consider self-perceived weight in conjunction with actual weight in their pursuit of weight management goals and in planning prevention programmes that guide weight loss behaviours for adolescents.

Prevalence and correlates of metabolic syndrome in pre-crisis Syria: call for current relief efforts.

This study aimed to assess the prevalence, components and correlates of metabolic syndrome (MetS) in adults in pre-crisis Aleppo, Syrian Arab Republic. We used a population-based, 2-stage cluster sampling method in a population of 557 men and 611 women, randomly selected from 83 residential neighbourhoods including many rural settlers. Sociodemographic and lifestyle characteristics, comorbidity, anthropometry and biochemical indices were measured. Prevalence of MetS was estimated at 39.6%, with comparable rates in men and women. Hypertension was the most prevalent component (56.6%), followed by central obesity (51.4%). Among women, education (12 years) was inversely associated with risk of MetS, while family history of obesity and diabetes was associated with an increased risk. The high prevalence of MetS and its components emphasizes the burden of cardiovascular diseases among adults in pre-crisis Aleppo. A system of surveillance and management for cardiovascular diseases needs to be incorporated into the current humanitarian response.

La présente étude avait pour objectif d'évaluer la prévalence, les composantes et les corrélats du syndrome métabolique chez l'adulte à Alep avant la crise, en République arabe syrienne. Nous avons utilisé une méthode d'échantillonnage en grappe à deux degrés basée sur une population de 557 hommes et 611 femmes, choisis de manière aléatoire dans 83 zones résidentielles, comprenant de nombreux habitants de zones rurales. Les caractéristiques socio-démographiques et relatives au mode de vie, les comorbidités, l'anthropométrie et les indices biochimiques ont été évaluées. La prévalence du syndrome métabolique a été estimée à 39,6%, avec des taux comparables entre hommes et femmes. L'hypertension était la composante la plus prévalente [56,6%], suivie par l'obésité centrale [51,4%]. Parmi les femmes, l'éducation était inversement associée au risque de syndrome métabolique, alors que des antécédents familiaux d'obésité et de diabète étaient associés à un risque accru. La forte prévalence du syndrome métabolique et de ses composantes met en évidence la charge des maladies cardio-vasculaires chez l'adulte à Alep avant la crise. Un système de surveillance et de prise en charge des maladies cardio-vasculaires doit être incorporé à la riposte humanitaire actuelle

Diet and the risk of head and neck squamous cell carcinomas in a Syrian population: a case-control study.

Diet has not been investigated as a potential risk factor for head and neck squamous cell carcinomas in the Syrian Arab Republic. In a hospital-based, unmatched case-control study 108 people with cancer and 105 controls were interviewed about dietary intake using a validated food frequency questionnaire in Arabic. Sociodemographic and health risk behavioural information were collected by a self-completed questionnaire. Adjusting for age, sex, education level, working status and tobacco smoking, the multiple regression analysis showed that low intake of vegetables (OR 3.8; 95% CI: 1.57-9.10), cereal/cereal products (OR 2.6; 95% CI: 1.12-5.99) and high-caffeine beverages (OR 3.2; 95% CI: 1.34-7.43) increased the risk of head and neck squamous cell carcinomas, whereas a low level of fats and oils intake decreased the risk (OR 0.6; 95% CI: 0.24-1.30). These findings should be considered in national health promotion programmes in the Syrian Arab Republic.

The Use of Complementary and Alternative Medicine among Lebanese Adults: Results from a National Survey.

Objective. To examine the prevalence and correlates of Complementary and Alternative Medicine (CAM) use in Lebanon. Methods. A cross-sectional survey was conducted through face to face interviews on a nationally representative sample of 1,475 Lebanese adults. The survey questionnaire explored the sociodemographic and health related characteristics as well as the types and modes of CAM use. The main outcome in this study was the use of CAM during the last 12 months. Results. Prevalence of CAM use was 29.87% with "folk herbs" being the most commonly used (75%). Two out of five CAM users indicated using it as alternative to conventional therapies and only 28.4% of users disclosed the use of CAM to their physician. CAM use was significantly associated with higher income, presence of a chronic disease, and lack of access to needed health care. Lower odds of CAM use were observed among older adults and those with a higher education level. Conclusions. This study revealed a high prevalence of CAM use in Lebanon. Health policy and decision makers need to facilitate proper regulation and integration of CAM into mainstream medicine and educate health care providers and the public alike on the safe and effective use of CAM therapies.

L'alimentation n'avait pas encore été étudiée comme facteur de risque potentiel pour le carcinoma squameux de la tête et du cou en République arabe syrienne.Dans une étude cas-témoins non appariés en milieu hospitalier,108 personnes atteintes d'un cancer et 105 témoins ont été interrogés sur leurs apports alimentaires en recourant à la version en langue arabe d'un questionnaire validé sur la fréquence de consommation alimentaire. Les données sociodémographiques et comportementales en matière de risque pour la santé ont été recueillies à l'aide d'un autoquestionnaire. Après ajustment en fonction de l'âge, du sexe,du niveau d'études et du statut professionnel et tabagique, l'analyse de régression multiple a révélé qu'une faible consommation de légumes [OR 3,8 ; IC à 95 % : 1,57-9,10], de céréales/produits céréaliers [OR 2,6 ; IC à 95 % : 1,12-5, 99] et de boissons à teneur élevée en caféine [OR 3,2 ; IC à 95 % : 1,34-7, 43] augmentaient le risque de carcinome squameux de la tête et du cou, tandis qu'un faible apport en graisses et en huiles réduisait ce risque [OR 0,6 ; IC à 95 % : 0,24 - 1,30]. Ces resultants doivent être pris en compte dans les programmes nationaux de promotion de la santé en République arabe syrienne

Association between dietary patterns and the risk of metabolic syndrome among Lebanese adults.

PURPOSE: The main objective of this study was to evaluate the association between dietary patterns and the metabolic syndrome (MetS) and its metabolic abnormalities among Lebanese adults, using data from a national nutrition survey. METHODS: A cross-sectional analysis involving adults aged ≥ 18 years (n = 323) with no prior history of chronic diseases was conducted. Participants completed a brief sociodemographic and 61-item food frequency questionnaire. Anthropometric measurements and fasting blood samples were also obtained. The International Diabetes Federation criteria were used to classify study participants with the metabolic syndrome. Dietary patterns were identified by factor analysis. Multivariate logistic regression analysis was used to evaluate the associations of extracted patterns with MetS and its metabolic abnormalities. RESULTS: Out of 323 participants, 112 (34.6%) were classified as having MetS. Three dietary patterns were identified: "Fast Food/Dessert," "Traditional Lebanese," and "High Protein." Compared with participants in the lowest quintile of the Fast Food/Dessert pattern, those in the highest quintile had significantly higher odds for MetS (OR, 3.13; 95% CI: 1.36-7.22) and hyperglycemia (OR, 3.81; 95% CI: 159-9.14). Subjects with the highest intake of the High Protein pattern had an increased risk for hypertension (OR, 2.98; 95% CI: 1.26-7.02). The Traditional Lebanese pattern showed no association with MetS or its components. CONCLUSIONS: The findings of this study demonstrate a positive association of the Fast Food/Dessert pattern with MetS and hyperglycemia among Lebanese adults. These results may guide the development of improved preventive nutrition interventions in this adult population.

Complementary feeding in the MENA region: practices and challenges.

Suboptimal feeding patterns during the first two years of life are key determinants of malnutrition in children and constitute an important predictor of health in later years. Early-childhood nutritional factors, stunting, and obesity have been highlighted as prominent core underlying factors of Non-Communicable Disease (NCD) development whereas the improvement of complementary feeding practices has been cited as one of the most effective preventive strategies for reducing malnutrition and adult NCDs. In the MENA region NCD prevalence shows very high rates and the limited available studies show that current practices fall behind global recommendations. Common to all countries of this region are practices of mixed breast and bottle-feeding as early as the first month, as well as the premature introduction of complementary foods. Early introduction of non-milk fluids, such as sweetened water and herbal teas, has been described as a common practice in the region and the premature introduction of complementary foods has been reported in as high as 80% of infants in several of the countries. Thus, enhancing infant/young child health can significantly reduce morbidities and mortalities, as well as adult-onset diseases, ultimately decreasing the region's overall burden of disease.

Dietary exposure to essential and toxic trace elements from a Total diet study in an adult Lebanese urban population.

This study assesses, by the Total diet study approach, the adequacy of micronutrient intake (Co, Cu, Fe, Mn, Ni, Zn) and the dietary exposure of a Lebanese adult urban population to two toxic elements (Cd, Pb). The foods that made up the average 'total diet' were derived from a previous individual consumption survey. A total of 1215 individual foods were collected, prepared and cooked prior to analysis. Analytical quantification was performed using inductively coupled plasma mass spectrometry. Average daily intakes of Co (11.4 microg/day), Cu (1104.19 microg/day), Fe (13.00 mg/day), Mn (2.04 mg/day), Ni (126.27 microg/day) and Zn (10.97 mg/day) were below toxicological reference values and were found to satisfy nutritional recommendations, except for manganese in men and iron in women. Average dietary exposure to Pb and Cd represented 3.2% and 21.7% of the respective provisional tolerable weekly intakes. Estimates of dietary intakes of iron appeared to be inadequate for 63% of adult women. These findings should constitute a current measure of assessing the adequacy and safety of foods consumed in Lebanon and may be a basis for future monitoring studies.
