“…9,10 BMI cutoff values derived to estimate a fat mass (FM) of 32% and 25% in 5-to 18-year-old Sri Lankan girls and boys, respectively, 11 which are lower than prevailing international cutoff values, have shown high sensitivity and specificity. 12 The higher value of international anthropometric cutoff values, compared with the Sri Lankan cutoff, would underestimate overnutrition and overestimate undernutrition. This could also be the possible explanation for the long-stagnating undernutrition rates in Sri Lankan children.…”

Despite socioeconomic improvement, undernutrition rates stagnate in Sri Lanka, while a slow rise in obesity and noncommunicable diseases (NCD) is seen. Inability to improve undernutrition and detection of NCD could be due to overdiagnosing stunting/wasting and underdiagnosing overweight/obesity. Obesity, being a risk factor for NCDs, needs correct tools for early diagnosis. Although body mass index (BMI) is a commonly used surrogate index, the validity of universal cutoffs is questioned. Evidence shows that body composition varies with ethnic origin and cutoff value reflecting fat mass (FM) varies in different ethnic groups. This study was conducted in 12 788, 5- to 15-year-old children from 8 schools in Negombo, Sri Lanka, to identify the validity of current anthropometric cutoffs. Obesity prevalence identified by body fat content was high. International BMI cutoffs had high specificity but varied sensitivity. Locally developed BMI cutoffs had high sensitivity and specificity. Validity of internationally developed anthropometric cutoffs in South Asian children is unsatisfactory; hence, locally/regionally developed anthropometric tools should be used for screening of obesity.

“…Prevalence of overweight and obesity were respectively 9.4% and 5.5% among teenage-girls in Batticaloa which in addition showed a 21.6% prevalence of central obesity [8]. Collectively, literature acknowledged that the prevalence of childhood obesity has been increasing over the time and shows a regional variation [6,9].…”

ObjectivesTo determine the prevalence of childhood overweight, obesity and metabolic abnormalities among children aged 12-15 years within the schools in Kandy Municipality area, Sri Lanka. DesignCross- sectional observational study.SettingRandomly selected schools in Kandy municipality areaMethodsThe anthropometric measurements of 1766 school children were taken and those who were overweight or obese were recruited for further evaluation of metabolic abnormalities.ResultsThere were 1053 (59.62%) boys and 713 (40.37%) girls of whom 258 (14.60%) were overweight or obese (7.81% overweight and 6.79% obese). This included 106 girls of whom, 64 were overweight and 42 were obese and 152 boys of whom, 74 and 78 were overweight and obese respectively. Central obesity was seen in 16.93% and 5.01% of them had normal body mass index. Eighty-five children out of the 258 with body mass index > 85th percentile reported for further evaluation and the prevalence of metabolic syndrome among them was 11.67% (5 girls and 5 boys). When borderline and abnormal levels of lipids were taken together, more than 50% of overweight and obese children were found to have dyslipidaemia. Elevated Alanine Amino Transaminase and Aspartate Amino Transaminase levels were reported in 33 (38.82%) and 7 (8.24%) respectively. Evidence of fatty liver was present in 34.69% based on abdominal ultra sound scan findings.ConclusionWhile prevalence rates of overweight, obesity and metabolic syndrome are comparable with other urban settings in the country as well as neighbouring countries in Asia, the study highlights the detection of lipid abnormalities suggestive of familial hyperlipidaemia which warrants further evaluation. NAFLD is also identified as a significant comorbidity. Central obesity is underestimated by British standards.

“…However, the sensitivity of the currently adopted cutoff values of these measures is not similar, thus posing the question of the validity of a single cutoff value universally [3]. Furthermore, anthropometric measures have shown poor detection of MetD [4] and the current BMI cutoff has been less sensitive in detecting obesity as well as MetD in Sri Lankan children [3,4]. A major drawback of BMI is that it does not distinguish between Fat Mass (FM) and Fat Free Mass (FFM) nor does it show the pattern of fat distribution as central or peripheral, of which the latter is more associated with MetD [2].…”

Background and objectives Although Body Mass Index (BMI) is used to assess obesity, it does not always relate to central obesity, the main metabolic risk factor. Waist to height ratio (WHtR) is a simple index of central obesity. This study assessed its usefulness in detecting metabolic derangements in 5-15 year old Sri Lankan children. Method A cross sectional descriptive study on healthy 5-15 year old children was conducted in Colombo district. Height, weight and Waist Circumference (WC) were measured. WHtR and BMI (classified by WHO cutoff >2SD) were calculated. Obesity was defined by percentage fat mass measured by Bio Electrical Impedance Assay (BIA -InBody-230 BIA machine) and validated against Sri Lanka body composition equations. After a 12-hour overnight fast, blood was drawn for Fasting Blood Glucose (FBG) and lipid profile. Standard Oral Glucose Tolerance Test (OGTT) was performed to obtain Random Blood Glucose (RBG) at 2 hours. Metabolic Derangements (MetD) were defined as; WC for age >90 th centile

Validity of newly-developed BMI and waist cut-off values for Sri Lankan children

Abstract: Internationally available BMI cut-off values are poor in diagnosing obesity in Sri Lankan children. Newly developed Sri Lankan BMI cut-off values for children improved the diagnosis. WC can be used successfully as an alternative diagnostic tool of obesity.
