SIBAI, ABLA MEHIO, NAHLA HWALLA, NADA ADRA, AND BOUSHRA RAHAL. Prevalence and covariates of obesity in Lebanon: findings from the first epidemiological study. Obes Res. 2003;11:1353-1361. Objective: To estimate the prevalence of overweight and obesity and examine associated covariates in the Lebanese population. Research Methods and Procedures:A cross-sectional survey of a representative sample of 2104 individuals, 3 years of age and older. Anthropometric measurements and dietary assessments were conducted following standard methods and techniques. Overweight and obesity (classes I to III) were defined according to internationally standardized criteria for classification of BMI. Results: For children 3 to 19 years of age, prevalence rates of overweight and obesity were higher overall for boys than girls (22.5% vs. 16.1% and 7.5% vs. 3.2%, respectively). For adult men and women (age Ն 20 years), the prevalence of overweight was 57.7% and 49.4%, respectively. In contrast, obesity (BMI Ն 30 kg/m 2 ) was higher overall among women (18.8%) than men (14.3%), a trend that became more evident with increasing obesity class. BMI, percentage of body fat, and waist circumference increased to middle age and declined thereafter. Whereas lack of exercise associated significantly with obesity among children, obesity in older adults was more prevalent among the least educated, nonsmokers, and those reporting a family history of obesity. Discussion: The results from this national population-based study in Lebanon show high prevalence rates of overweight and obesity comparable with those observed in developed countries such as the United States. While further studies are needed to examine the underlying social and cultural factors associated with lifestyle and nutritional habits, now is the time to institute multicomponent interventions promoting physical activity and weight control nationwide.

Objective: To identify and characterize dietary patterns in Lebanon and assess their association with sociodemographic factors, BMI and waist circumference (WC). Design: A cross-sectional population-based survey. In a face-to-face interview, participants completed a brief sociodemographic and semiquantitative FFQ. In addition, anthropometric measurements were obtained following standard techniques. Dietary patterns were identified by factor analysis. Multivariate linear regression was used to assess determinants of the various patterns and their association with BMI and WC.

BackgroundEven though the obesity epidemic continues to grow in various parts of the world, recent reports have highlighted disparities in obesity trends across countries. There is little empirical evidence on the development and growth of obesity in Lebanon and other countries of the Eastern Mediterranean Region. Acknowledging the need for effective obesity preventive measures and for accurate assessment of trends in the obesity epidemic, this study aims at examining and analyzing secular trends in the prevalence of overweight and obesity over a 12-year period in Lebanon.MethodsBased on weight and height measurements obtained from two national cross-sectional surveys conducted in 1997 and 2009 on subjects 6 years of age and older, BMI was calculated and the prevalence of obesity was determined based on BMI for adults and BMI z-scores for children and adolescents, according to WHO criteria. Age -and sex- adjusted odds ratios for overweight and obesity were determined, with the 1997 year as the referent category. Annual rates of change in obesity prevalence per sex and age group were also calculated.ResultsThe study samples included a total of 2004 subjects in the 1997 survey and 3636 in the 2009 survey. Compared to 1997, mean BMI values were significantly higher in 2009 among all age and sex groups, except for 6–9 year old children. Whereas the prevalence of overweight appeared stable over the study period in both 6–19 year old subjects (20.0% vs. 21.2%) and adults aged 20 years and above (37.0% vs. 36.8%), the prevalence of obesity increased significantly (7.3% vs. 10.9% in 6–19 year olds; 17.4% vs. 28.2% in adults), with the odds of obesity being 2 times higher in 2009 compared to 1997, in both age groups (OR = 1.96, 95% CI:1.29-2.97 and OR = 2.01, 95% CI: 1.67-2.43, respectively). The annual rates of change in obesity prevalence ranged between +4.1% in children and adolescents and +5.2% in adults.ConclusionThe study’s findings highlight an alarming increase in obesity prevalence in the Lebanese population, over the 12-year study period, and alert to the importance of formulating policies and nutritional strategies to curb the obesity rise in the country.

PurposeThe 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.MethodsA 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.ResultsOut 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.ConclusionsThe 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.

Aim: To examine the burden of cardiovascular disease (CVD) risk factors in Middle East and North Africa countries and their associations with dietary behaviors as nutrition transition is unfolding in the region. Data: Data on CVD risk factors were collected from scholarly papers and a systematic review of published articles was performed. Dietary patterns were derived from the WHO Food and Agriculture Organization Statistical Databases. Results: Wide variations exist across countries in the prevalence of CVD risk factors, namely obesity, diabetes, hypertension, hyperlipidemia, smoking and physical inactivity, with some countries showing high values of certain factors which approach those observed in the developed world. In particular, obesity prevalence rates have reached alarming levels, particularly among women in the oil-rich countries (over 40%), making it the most pressing health concern in the region. Trends in the dietary pattern illustrated a consistent rise in total energy supply by approximately 730 kcal per capita per day between 1970 and 2005. Dietary patterns showed an increased consumption of fat and animal protein and a decreased intake of carbohydrates, particularly whole grain cereals, and fresh fruits and vegetables. Conclusion: Regional differences were attributed to differences in lifestyle, occupation and a shift from traditional food habits. Our understanding of the CVD disparities across various geographic regions is key to our effort in planning relevant intervention programs. Public health efforts should focus on obesity, physical inactivity and unhealthy dietary practices. The success of these interventions depends on governmental commitment, multisectoral partnership and a consideration of the sociocultural norms of the target population.
