Prevalence of metabolic syndrome among school children aged 6–18 years in Ein Al-Helwa Palestinian Refugee Camp, Lebanon: a cross-sectional study

Abstract

BackgroundMetabolic syndrome is characterised by the presence of several metabolic abnormalities, including hyperglycaemia, central obesity (also known as abdominal obesity), elevated blood pressure, and an abnormal blood lipid profile. The prevalence of metabolic syndrome is rising rapidly around the world as childhood obesity is increasing. The aim of this study is to determine the prevalence of metabolic syndrome in school children aged 6–18 years residing in Ein Alhelwe Refugee camp in Saida, Lebanon. MethodsSchool children aged 6–18 years from the first to twelfth grades from two United Nations Relief and Works Agency (UNRWA) schools were randomly chosen. We used a school-based cross-sectional study design with two stages. The first stage included measurements of weight, height, body mass index (BMI), waist circumference, and blood pressure. In the second stage, blood tests were carried out for fasting blood sugar, triglycerides, and high-density lipoprotein (HDL). Approval was obtained from the ethics committee at Al Hamshari Hospital in Saida, Lebanon. Written permission was obtained from the UNRWA and the principals of the two schools for the first stage, and informed written consent was obtained from parents on behalf of the children involved in the second stage of the study. FindingsThe first stage of the research included 487 participants (258 female, 229 male) and the second stage included 73 participants (36 overweight participants [12 male, 24 female] and 37 obese participants [19 male, 18 female]). The prevalence of overweight and obesity were 15·2% (74 of 487) and 14·4% (70 of 487) among all age groups, respectively. Among Palestinian refugee school children in Saida aged 10–18 years, the prevalence of metabolic syndrome was more pronounced when the modified National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP-III) definition was used (30·9%; 21 of 68) compared to the International Diabetes Federation (IDF) definition (11·8%; eight of 68), with no statistical differences between male and female participants. Note that the IDF definition can be applied to children aged 10–18 years, of whom there were 68 participants, and for comparison between IDF and NCEP ATP-III, prevalence of metabolic syndrome was calculated for participants in this age range. Low HDL cholesterol (52·1%; 38 of 73), central obesity (46·6%; 34 of 73), and raised blood pressure (42·5%; 31 of 73) were the leading three common metabolic abnormalities among children who were overweight or obese. InterpretationThis study has shown that metabolic syndrome is common among children who are obese or overweight, who are aged 10–18 years, living in Ein Al-Helwa Refugee Camp in Saida, Lebanon. These data raise the importance of early prevention and treatment of metabolic syndrome and its components (abdominal obesity, elevated triglycerides, reduced HDL cholesterol, elevated blood pressure, and elevated blood glucose) to reduce the risk of diabetes and cardiovascular complications in susceptible individuals. A potential limitation of this study is that the small sample size may not accurately reflect the prevalence of metabolic syndrome.
