Prevalence of different states of glucose intolerance in Sri Lankan children and adolescents with obesity and its relation to other comorbidities.

BACKGROUND: South Asian adults have higher prevalence of obesity comorbidities than other ethnic groups. Whether this also is true for Sri Lankan children with obesity has rarely been investigated. OBJECTIVE: To investigate prevalence of glucose intolerance and other comorbidities in Sri Lankan children with obesity and compare them with Swedish children. To identify risk factors associated with glucose intolerance. SUBJECTS: A total of 357 Sri Lankan children (185 boys), aged 7 to 17 years with BMI-SDS ≥2.0 from a cross-sectional school screening in Negombo. A total of 167 subjects from this study population were matched for sex, BMI-SDS and age with 167 Swedish subjects from the ULSCO cohort for comparison. METHODS: After a 12 hour overnight fast, blood samples were collected and oral glucose tolerance test was performed. Body fat mass was assessed by bioelectrical impedance assay. Data regarding medical history and socioeconomic status were obtained from questionnaires. RESULTS: Based on levels of fasting glucose (FG) and 2 hours-glucose (2 hours-G), Sri Lankan subjects were divided into five groups: normal glucose tolerance (77.5%, n = 276), isolated impaired fasting glucose according to ADA criteria (9.0%, n = 32), isolated impaired glucose tolerance (8.4%, n = 30), combined impaired fasting glucose (IFG) + impaired glucose tolerance (IGT) (3.1%, n = 11) and type 2 diabetes mellitus (2.0%, n = 7). FG, 2 hours-insulin and educational status of the father independently increased the Odds ratio to have elevated 2 hours-G. Sri Lankan subjects had higher percentage of body fat, but less abdominal fat than Swedish subjects. CONCLUSION: High prevalence in Sri Lankan children with obesity shows that screening for glucose intolerance is important even if asymptomatic.

Micronutrient status and associated factors of adiposity in primary school children with normal and high body fat in Colombo municipal area, Sri Lanka.

BACKGROUND: The prevalence of obesity and associated risk of chronic diseases are increasing among the paediatric population. The effectiveness of preventive measures and interventions are likely to improve when all factors which associate with obesity in a specific target group are considered. Currently such comprehensive data is unavailable for Sri Lankan children aged 8-9 years. METHODS: This paper pertains to the data collected from August-2015 to November-2016 for a case-control study which included cases (high body fat) (N = 160; males-81) and controls (normal body fat) (N = 164; males-80) recruited from primary schools in the Colombo Municipal area. Anthropometry and body composition (Bioelectrical impedance analysis-BIA) were measured. Diet, physical activity and socio-demographic data were collected using validated interviewer administered questionnaires. Serum concentrations of vitamins A, D [25(OH)D], E, folate (serum and red blood cell-RBC), zinc (Zn), selenium (Se), copper (Cu), iron (Fe), magnesium (Mg), calcium (Ca), chromium (Cr), manganese (Mn), cobalt (Co), ferritin, leptin and high sensitivity C-reactive protein (hs-CRP) were assessed using fasting blood samples. RESULTS: Cases were from higher socio-economic strata and spent significantly less time on physical activities, more time on sedentary behaviours and consumed higher energy compared to the controls. Cases from both genders had significantly lower levels of vitamin D [25 (OH)D], Fe and Mg (all p < 0.05) and higher levels of Cu and Ca (all p < 0.01) compared to controls. Higher levels of ferritin and Cr were seen among male (p < 0.001) and female (p > 0.05) cases compared to the controls. However, total serum folate levels were lower in male (p < 0.01) and female (p > 0.05) cases while the RBC folate levels were higher among male (p < 0.01) and female (p > 0.05) cases compared with controls. Vitamins A, E, Se, Mn and Co (p > 0.05) were not significantly different between groups. The inflammatory markers, both hs-CRP and leptin levels were higher among cases (p < 0.001) compared to the controls. CONCLUSIONS: This study highlights higher socio-economic status, lower physical activity, more sedentary behaviours, higher energy intake and inconsistent distribution of micronutrients among the children with high body fat when compared with the control group. Increased levels of inflammatory markers indicate the presence of the risk of chronic inflammation in children with high body fat.

Evaluation of biochemical and haematological changes in dengue fever and dengue hemorrhagic fever in Sri Lankan children: a prospective follow up study.

BACKGROUND: Series of biochemical and haematological changes occur during the course of dengue infection, which vary depending on the clinical disease. The patterns of change are not well documented and identifying these patterns in children with dengue infection would help to anticipate the progression to different clinical stages thus enabling effective management. METHODS: A prospective follow up study was conducted during the period of July 2013 - April 2014 at Professorial Pediatric unit, Lady Ridgeway Hospital for Children, Colombo, Sri Lanka. Children (5-12 years) admitted within the first 84 h of fever, with a clinical diagnosis of dengue infection were recruited. Children who became positive for dengue IgM were included in the final analysis. Blood was collected on admission for complete blood count, Alanine aminotransferase, Aspartate aminotransferase, albumin, cholesterol and corrected calcium. These tests were repeated at 12 hourly intervals during the hospital stay. RESULTS: Data of 130-subjects were analyzed (Dengue fever /Dengue hemorrhagic fever: 100/30). There was a significant difference in the pattern of white cell counts, platelets and haematocrit in the two clinical groups. Both transaminase rose initially in both dengue fever and dengue hemorrhagic fever and a steep rise were seen between 8th and 9th days in hemorrhagic fever. Both albumin and cholesterol decreased significantly at the time of entering into the critical phase. According to Receiver operating characteristic curve analysis, albumin level crossing 37.5g/L (sensitivity 86.7%, specificity 77.8%) and a 0.38 mmol/L reduction in cholesterol level (sensitivity 77.3%, specificity 71.9%) between day 3 and 4 were the best predictors of entering into critical phase. Calcium levels did not show any distinct pattern. CONCLUSIONS: There is a clear difference in the pattern of change of both hematological and biochemical parameters in dengue fever and dengue hemorrhagic fever. Reduction in albumin and cholesterol levels seen between the completion of day 3 and day 4 were highly valid predictors of entering into critical phase in dengue hemorrhagic fever.

Burnout among postgraduate doctors in Colombo: prevalence, associated factors and association with self-reported patient care.

BACKGROUND: Postgraduate doctors are prone to burnout due to occupational and educational stressors. Sri Lankan situation is unknown. This study determines burnout among postgraduate doctors in Colombo: Prevalence, associated factors, and association with self-reported patient care. METHODS: A cross-sectional study was conducted among 278 postgraduate doctors from eight specialties working in Colombo district, attached to the main postgraduate training institute for medical professionals. A self-administered questionnaire was used. It comprised of the Copenhagen Burnout Inventory and an author-developed questionnaire, which was used to assess, associated factors and self-reported patient care. Prevalence of burnout was calculated. Associations were analysed using chi-square and binary logistic regression. RESULTS: The response rate was 88.1% (n = 245). The prevalence of personal, work-related and client-related burnout was 41.6% (95% CI = 35.5-47.8%), 30.6% (95% CI = 24.8-36.4%), 8.9% (95% CI = 5.4-12.5%) respectively. Personal burnout was positively associated with, the trainee being a female, having a chronic disease, being involved in frequent unhealthy habits, having doctor parents, having home-work demands and having emotional demands. It was negatively associated with, having frequent healthy habits, being satisfied with skill development opportunities, and frequent use of deep studying. Work-related burnout was positively associated with, female gender, being involved in frequent unhealthy habits, having home-work demands and having emotional demands. It was negatively associated with, frequent use of deep methods of studying. Client-related burnout was positively associated with having emotional demands and negatively associated with being satisfied with training. The frequent self-reported, suboptimal patient-care practices: poor communication, poor clinical practice, poor response to patient's needs and poor communication during handing over were associated positively with client-related burnout. CONCLUSIONS: Most postgraduate doctors in Colombo have high personal and work-related burnout but client-related burnout is less. The factors associated with burnout need to be addressed by the programme managers of the postgraduate courses. Preventive measures should be introduced to reduce burnout among future postgraduate trainees of Colombo.

Association of Serum Uric acid and Gamma-glutamyltransferase with Obesity Related Metabolic Derangements in a Cohort of Children with Obesity in Sri Lanka

Introduction: Gamma-glutamyltransferase (GGT) and serum uric acid (UA) are known to be associated with cardiovascular disease in obese children Objectives: To determine the association of serum UA and GGT with components of metabolic syndrome (MetS) in a group of obese children and determine the validity of UA and GGT in predicting MetS. Methods: Cross sectional analytical study was conducted among 205, 5-15 year old obese children. After a 12- hour overnight fast, blood was drawn for glucose, lipid profile, alanine aminotransferase (ALT), aspartate aminotransferase (AST), insulin, UA and GGT. Oral glucose tolerance test (OGTT) was done with 2 hour plasma glucose. Height, weight, waist circumference, blood pressure and fat mass were measured. USS of abdomen was performed to assess hepatic steatosis. Results: Chi square test showed statistically significant associations between GGT and UA with triglyceride, insulin resistance (HOMA-IR), AST, ALT, AST/ALT ratio and fatty liver. Additionally UA showed a significant association with the OGTT. With existing cut offs (GGT >30 U/L and UA >330 µmol/L) the sensitivity and specificity of GGT in predicting MetS was 19% (95% CI, 13.63-24.37) and 88.4% (95% CI, 84.02-92.78) respectively while for UA was 28.6% (95% CI, 22.42-34.78) and 80.2% (95% CI, 74.75-85.65) respectively. A new cut off value of 19.5 U/L (sensitivity 56% and specificity 55%) for GGT and 275.5 µmol/L (sensitivity 61% and specificity 54%) for UA predicted MetS with greater accuracy. Conclusion: GGT and UA are strongly associated with metabolic derangements and these biomarkers are rather weak in predicting MetS.

Seroprevalence of Bordetella pertussis specific Immunoglobulin G antibody levels among asymptomatic individuals aged 4 to 24 years: a descriptive cross sectional study from Sri Lanka.

BACKGROUND: In Sri Lanka pertussis continues to circulate in the community and cases among adolescents and adults have been reported despite 95% coverage of the four dose pertussis vaccination during early childhood. Waning of immunity following natural infection or immunization may contribute to the persistent circulation. An adolescent booster dose is not included in the national immunization schedule of Sri Lanka, although this is routine practice in many countries. Therefore information on immunity to pertussis in the adolescent group is needed prior to considering vaccination schedule changes. METHODS: The quantitative determination of specific Immunoglobulin G antibodies to Bordetella pertussis toxin was done using a commercially available validated ELISA method. The antibody values were categorized into groups according to the interpretive criteria provided by the manufacturer. The values were <55 IU/mL, negative; 55-<60 IU/mL, borderline; 60-125 IU/mL, positive; >125, strongly positive respectively. Sera of 385 asymptomatic individuals aged 4 to 24 years admitted to surgical units of Lady Ridgeway Hospital, Colombo and Colombo South Teaching Hospital were used for the study. Mann-Whitney U and Kruskal-Wallis tests were used in analysis of results and p ≤0.05 was considered as statistically significant. Details of epidemiological variables were collected using a questionnaire and correlation with significant levels of pertussis antibodies was determined. RESULTS: Median age of the study population was 12 years with 212 (55.1%) females. The median anti PT antibody level was 3.31 IU/mL and 352 (91%) had anti PT levels ≤55 IU/mL. Median of anti PT levels were 3.18 IU/mL for 4-7 years, 1.43 IU/mL (IQR 0.336-6.27) for 8-11 years, 4.28 IU/mL (IQR 0.978-13.39) for 12-15 years, 6.14 IU/mL for 16-19 years and 4.89 IU/mL for 20-24 years and the differences were statistically significant (p = 0.000). Females (p < 0.003) and those having a sibling aged ≥12 years (p = 0.017) had significantly higher anti PT levels. CONCLUSIONS: The majority of the study population, especially 8 to 11 year age group had low anti PT IgG levels. The higher antibody titers in the 12-15 year age group seem to indicate infection in early adolescence. A booster dose of acellular pertussis vaccine need to be considered.

Assessing health workers' revenues and coping strategies in Nigeria--a mixed-methods study.

BACKGROUND: The setting of realistic performance-based financing rewards necessitates not just knowledge of health workers' salaries, but of the revenue that accrues from their additional income-generating activities. This study examined the coping mechanisms of health workers in the public health sector of Nasarawa and Ondo states in Nigeria to supplement their salaries and benefits; it also estimated the proportionate value of the revenues from those coping mechanisms in relation to the health workers' official incomes. METHODS: This study adopted a mixed-methods approach, consisting of semi-structured interviews, a review of policy documents, a survey using self-administered questionnaires, and the randomized response technique (RRT). In all, 170 health workers (86 in Ondo, 84 in Nasarawa) participated in the survey. In-depth interviews were conducted with 24 health workers (12 per state) and nine policy makers from both states. RESULTS: The health workers perceived their salaries as inadequate, though most policy makers differed in this assessment. There appeared to be a considerable expenditure-income disparity among the respondents. Approximately 56% (n = 93) of the study population reported having additional earning arrangements: most reported non-medical activities such as farming and trading, but private practice was also frequently reported.Half of the respondents with additional earning arrangements stated that their income from those activities was the equivalent of half or more of their monthly salaries. Specifically, 35% (n = 32) said that they earned about half of their official monthly salaries and 15% (n = 14) reported earning the same or more than their monthly salaries from these activities. Other coping mechanisms used by the health workers included prioritizing activities that enabled the earning of per diems, collecting informal payments and gifts from patients, and pilfering drugs from facilities. CONCLUSIONS: Predatory and non-predatory mechanisms accounted for the health workers' additional income. It may be difficult for the health workers to meet their expenses with their salaries and financial incentives; this highlights the need for the regulation of additional earnings and to implement targeted accountability mechanisms. This study indicates the value of using mixed methods when investigating sensitive issues. Future studies of this type should employ mixed methods for triangulation purposes to provide better insight into health workers' responses.

A systematic review of outcome and impact of master's in health and health care.

BACKGROUND: The 'human resources for health' crisis has highlighted the need for more health (care) professionals and led to an increased interest in health professional education, including master's degree programmes. The number of these programmes in low- and middle-income countries (LMIC) is increasing, but questions have been raised regarding their relevance, outcome and impact. We conducted a systematic review to evaluate the outcomes and impact of health-related master's degree programmes. METHODS: We searched the databases Scopus, Pubmed, Embase, CINAHL, ERIC, Psychinfo and Cochrane (1999 - November 2011) and selected websites. All papers describing outcomes and impact of health-related Master programmes were included. Three reviewers, two for each article, extracted data independently. The articles were categorised by type of programme, country, defined outcomes and impact, study methods used and level of evidence, and classified according to outcomes: competencies used in practice, graduates' career progression and impact on graduates' workplaces and sector/society. RESULTS: Of the 33 articles included in the review, most originated from the US and the UK, and only one from a low-income country. The programmes studied were in public health (8), nursing (8), physiotherapy (5), family practice (4) and other topics (8). Outcomes were defined in less than one third of the articles, and impact was not defined at all. Outcomes and impact were measured by self-reported alumni surveys and qualitative methods. Most articles reported that competencies learned during the programme were applied in the workplace and alumni reported career progression or specific job changes. Some articles reported difficulties in using newly gained competencies in the workplace. There was limited evidence of impact on the workplace. Only two articles reported impact on the sector. Most studies described learning approaches, but very few described a mechanism to ensure outcome and impact of the programme. CONCLUSIONS: Evidence suggests that graduates apply newly learned competencies in the field and that they progress in their career. There is a paucity of well-designed studies assessing the outcomes and impact of health-related master's degree programmes in low- and middle-income countries. Studies of such programmes should consider the context and define outcomes and impact.

Development and validation of the Quality of Work Life Scale for elderly workers.

BACKGROUND: With the rapid rise in the elderly population and their labour force participation, quality of work life (QoWL) of elderly workers becomes an important concept. A valid instrument to measure elderly workers QoWL is a prerequisite to further in this direction. OBJECTIVE: To develop and validate the Quality of Work Life Scale-Elderly (QoWLS-E) for elderly workers 60 years and above in Sri Lanka. METHODS: The development and validation of 35 items in QoWLS-E was carried out in two stages. Using a literature search and expert opinion, the items were developed in English language and later translated to Sinhala language. The initial scale consisted of 38 items and a principle component analysis (PCA) was conducted among 275 elderly workers in selected administrative divisions of Colombo district. Then a confirmatory factor analysis (CFA) was conducted among a separate group of 250 elderly workers to confirm the factor structure of the developed scale. RESULTS: PCA identified 9 principle components accounting for a variance of 71%, which was later confirmed in the CFA (RMSEA-0.07, SRMR-1.0, NNFI-0.87, GFI-0.82, CFI-0.96). The final QoWLS-E with a structure of 9 domains namely; physical health, psychological, welfare facility, safety, job content, co-worker, supervisor, flexibility and autonomy having 35 items correlated satisfactorily with Cronbach's alpha of 0.77 and test - retest reliability of 0.82. CONCLUSION: QoWLS-E is conceptually and culturally appropriate to assess Quality of Work Life Scale in elderly. It could be a useful tool to describe and monitor improvement of QOWL in elderly.

Prediction Equation for Physical Activity Energy Expenditure in 11-13-Year-Old Sri Lankan Children.

This study aimed to develop a regression equation to predict physical activity energy expenditure (PAEE) using accelerometry. Children aged 11-13 years were recruited and randomly assigned to validation (n = 54) and cross-validation (n = 25) groups. The doubly labelled water (DLW) technique was used to assess energy expenditure and accelerometers were worn by participants across the same period. A preliminary equation was developed using stepwise multiple regression analysis with sex, height, weight, body mass index, fat-free mass, fat mass and counts per minute (CPM) as independent variables. Goodness-of-fit statistics were used to select the best prediction variables. The PRESS (predicted residual error sum of squares) statistical method was used to validate the final prediction equation. The preliminary equation was cross-validated on an independent group and no significant (p > 0.05) difference was observed in the PAEE estimated from the two methods. Independent variables of the final prediction equation (PAEE = [0.001CPM] - 0.112) accounted for 70.6% of the variance. The new equation developed to predict PAEE from accelerometry was found to be valid for use in Sri Lankan children.

A systematic review and meta-analysis of the effectiveness of individual-level interventions to reduce occupational stress perceptions among teachers.

Teachers are largely affected by OS, during their most productive years, leading to catastrophic physical, psychological, and economic burden on themselves, families and society by large. Teachers are responsible for producing the workforce of any nation, and thus have a major impact indirectly on the economy and health of a nation. There are several individual-level interventions conducted to reduce occupational stress (OS) among teachers. This study was conducted to systematically review and conduct a meta-analysis of the effectiveness of individual-level interventions to reduce occupational stress among teachers. This review was registered in the International Prospective Register of Systematic Reviews (PROSPERO; Registration ID: CRD42020149277) and followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, Scopus, Cochrane, PsycInfo, and Web of Science databases were searched using predefined search strategies covering the eligibility criteria. Studies were selected in four rounds. Risk of bias assessments were conducted with GRADE recommendations and ROBINS-I criteria for randomized and non-randomized interventions, respectively. Study selection, data extraction and bias assessments were performed independ ently by two reviewers with a third reviewer to resolve conflicts. Narrative synthesis of the findings were also performed. Clinical, methodological, and statistical heterogeneity assessments were conduct ed. Meta-analyses were performed with Review Manager 5.3 software using the "generic inverse variance method" with mean difference as the pooled estimate. Sensitivity analyses of the findings was also performed. At the initial search, 293 articles were identified and 29 subsequently selected for synthesis of findings. The findings of the meta-analysis indicated that Cognitive Behavioral Therapy (CBT) and relaxation interventions significantly reduced OS among teachers with an effect size of 6.2 (p < 0.001). Effect size was highest for combined CBT and relaxation interventions which was 6.57 (p < 0.001). Relaxation interventions only and CBT interventions only had effect sizes of 3.35 (p < 0.001) and 3.12 (p = 0.002) respectively. In sensitivity analysis, after removing low-quality studies, CBT interventions only, combined CBT and relaxation interventions and overall effect size were 6.31 (p < 0.00001), 17.36 (p < 0.00001), and 14.55 (p < 0.00001), respectively, ie, substantially greater than with low-quality studies included. Inconclusion, CBT and relaxation interventions reduce OS among teachers and it's most effective when those individual-level interventions are conducted together.

Metabolic Abnormalities in a Cohort of Overweight and Obese Children in an Urban Setting of Sri Lanka.

Childhood obesity-related metabolic derangements are increasing among South Asian populations. Most of these changes persist to adulthood. This study aims to describe the distribution of metabolic abnormalities among 7- to 17-year-old overweight and obese children in the Gampaha District of Sri Lanka. Overweight children (age- and gender-adapted BMI>+1SD, WHO standards) were selected from a community survey carried out in the Negombo Education Zone of Gampaha District. After a 12-hour overnight fast, blood was drawn, and blood glucose (FBG), lipid profile, insulin, and liver transaminases were measured. Two hours after a glucose load, blood was drawn for random blood glucose (RBG) and insulin. Metabolic syndrome (MetS) was diagnosed using modified IDF criteria for children. Anthropometry, fat mass (FM), and blood pressure were measured. Hepatic fat pattern was assessed ultrasonically. The data of 403 children (210 boys) were analysed. Of the study population, 16.4% were overweight (BMI for age +1 to +2SD), 72% were obese (BMI for age >+2 to +3SD), and 11.6% were severely obese (BMI for age >+3SD). Insulin resistance was seen in 46.8%, and prevalence increased with age. Mean postprandial insulin ranged from 368 to 625 pmol/L and was elevated in 35%. Dysglycaemia was seen among 20.8%. MetS was present in 19.8%, and 84% had at least one metabolic abnormality. Different degrees of hepatic steatosis were observed in 32.5%, and elevated ALT/AST ratio was seen in 58% of the population. Overweight and obesity during childhood were associated with multiple metabolic abnormalities including MetS, and they occur from a young age. It is important to screen children for overweight/obesity early in life and intervene to prevent them from developing metabolic complications.

Efficacy and safety of two Ayurvedic dosage forms for allergic rhinitis: Study protocol for an open-label randomized controlled trial.

BACKGROUND: Allergic rhinitis (AR) is an immune response of the nasal mucosa to airborne allergens and involves nasal congestion, watery nasal discharge, itching of the nose, and sneezing. The symptoms of allergic rhinitis may significantly affect a patient's quality of life and can be associated with conditions such as fatigue, headache, cognitive impairment, and sleep disturbances. Various complementary and alternative medicine treatments have been used for this condition in clinical practice. The Ayurveda system of medicine is the most common complementary medicine system practiced in Sri Lanka. The aim of this study is to examine the efficacy and safety of a decoction used in traditional Ayurveda for allergic rhinitis and its ready- to-use freeze dried formulation in comparison to an antihistamine over a period of 4 weeks on relief of symptoms in allergic rhinitis. STUDY DESIGN: This is a three-arm, open-label, non-inferiority, randomized controlled clinical trial enrolling patients with AR. Tamalakyadi decoction containing 12 ingredients (TMD12), used in traditional Ayurveda and its freeze-dried formulation are the test products. The efficacy and safety of the two Ayurvedic dosage forms will be tested against the antihistamine loratadine. Patients with symptoms of AR will be allocated randomly into the three arms after a 1-week run-in period and the medications will be given orally for 28 days. Total Nasal symptom Score (TNSS) of the patients will be used as the primary efficacy endpoint. TNSS will be recorded and compared between the three arms prior to visit 1, at the end of 28 days, and end of the first and second months of follow-up. Symptom scores of daytime nasal symptoms, night time nasal symptoms, non-nasal symptoms and health-related quality of life questionnaire are used as secondary end points. DISCUSSION: This clinical trial will be able to provide evidence-based scientific data on Ayurvedic dosage form, TMD12, and the freeze-dried formulation in the treatment of allergic rhinitis. This trial is expected to develop capacity to scientifically evaluate various Ayurvedic treatments that are claimed to have efficacy in treatment of various disease conditions. TRIAL REGISTRATION: ISRCTN18149439 (6 May 2019).

Assessment of Nutritional Status in Sri Lankan Children: Validity of Current Anthropometry Cutoffs?

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.

Hyperglycemia in pregnancy among South Asian women: A single tertiary care center experience from Colombo, Sri Lanka.

AIM: To study case mix, risk factors, adverse outcomes and associations of hyperglycemia in pregnancy in a cohort of Sri Lankans. METHODS: Prospective observational study, from April 2011-October 2015 at a tertiary care referral center, Colombo, Sri Lanka. Data from first trimester to delivery of HIP was analyzed. Three subgroups were defined: Diabetes in pregnancy (DIP), Hyperglycemia in early Pregnancy (HIEP) [<24 weeks] and Gestational diabetes (GDM) [>24 weeks]. RESULTS: Of 782 patients 572 (73.1%) had complete data. Case-mix: 137(24.0%) DIP, 331(57.9%) GDM and 104 (18.2%) HIEP. Primigravidae commoner in GDM (<0.05). DIP older - mean 33.3 ±â€¯5.5 years (<0.01). Previous GDM commoner and pharmacological interventions needed in DIP and HIEP. Majority GDM (66.8%) required Medical Nutrition Therapy (MNT) alone. There was no difference in pregnancy outcomes between the 3 subgroups. Macrosomia significantly greater in HIEP (33.7%); neonatal cardiac defects more in DIP and HIEP. CONCLUSIONS: Increasing maternal age is a significant risk for DIP, while previous GDM is a risk for DIP and HIEP and neonatal congenital cardiac defects in subsequent pregnancies of South Asian women. We recommend preconception screening for glucose intolerance and achieving normoglycaemia among South Asian women with advanced maternal age and previous GDM.

Metformin in the Management of Childhood Obesity: A Randomized Control Trial.

BACKGROUND: Childhood obesity-related metabolic derangements are increasing among South Asian populations. Dietary and physical activity plans have limited effect. This study aims to assess the effectiveness of metformin in the management of obesity among 8- to 16-year-old children in Gampaha District of Sri Lanka. MATERIALS AND METHODS: A triple-blinded controlled trial was conducted on 150 obese school children. After 12-hour overnight fast, blood was drawn for fasting blood glucose (FBG) and lipid profile. Anthropometry, fat mass (FM), and blood pressure were measured. BMI and insulin resistance were calculated. Children randomly received either metformin (8-10 years-500 mg 12 hourly; 11-16 years-1 g 12 hourly) or placebo. Anthropometry and blood investigations were repeated at 6 and 12 months. Mean difference in outcome measures, adjusted for baseline values, was compared using ANCOVA. RESULTS: There were 84/150 boys. Metabolic syndrome was present in 25 (16.7%). A statistically significant adjusted mean reduction was observed in the metformin group compared with placebo, in weight (-0.991 vs. 1.394, p = 0.000), BMI/Age-standard deviation score (SDS; -0.287 vs. -0.116, p = 0.000), %FM/Age-SDS (-0.092 vs. 0.016, p = 0.04), systolic blood pressure (SBP; -0.415 vs. 0.015, p = 0.015), total cholesterol (-0.95 vs. -0.7, p = 0.001), low-density lipoprotein (-0.67 vs. -0.45, p = 0.001), and highly sensitive C-reactive protein (-1.36 vs. 0.08, p = 0.013) at 6 months, and in BMI/Age-SDS (-370 vs. -0.222, p = 0.001), WC/Age-SDS (-0.473 vs. -0.337, p = 0.018), SBP (-0.834 vs. -0.477, p = 0.023), and triglycerides (-0.33 vs. -0.14, p = 0.019) at 12 months. CONCLUSIONS: Metformin compared with placebo has beneficial effects on anthropometric and metabolic indicators in the management of childhood obesity.

Resource allocation in public hospitals: is it effective?

The allocative inefficiency is a fundamental flaw in the public hospitals of the developing countries. The inefficiencies drain the limited public resources allotted for healthcare. Sri Lanka's public health system faces worsening budget constraints. The resource allocation practices of the Ministry of Health focus on increasing the cadre of hospital staff, consequently crowding out the investments on facility development. The purpose of the study is to assess the impact of resource allocation in the tertiary-care public hospitals that are under the central Ministry of Health. The model is based on the assumption that the hospital managers and other agents of a public hospital pursue the objective of quality maximization (in the absence of a profit motive). The inpatient mortality rate is selected as the indicator of quality. With the use of panel data fixed-effects, and first-differencing estimation methods, we study the impact of the resource allocation on the hospital mortality rates. The selected models are statistically significant at 0.1% level. The elasticity effect of the capital is considerably larger than the effects of the human resources, in servicing the patients. The results suggest that the human resource utilization is suboptimal, due to the inadequacy of the capital (i.e. medical equipment, etc.).

Exposure to polychlorinated biphenyls (PCBs) among welders in Sri Lanka.

Polychlorinated biphenyls (PCBs) are a group of persistent organic pollutants with the ability to cause adverse impacts on human health and the environment. This study describes the indiscriminate use of PCB-contaminated transformer oil as a coolant in informal welding shops in Kalutara, Sri Lanka. Sixty-three welders, one each from a convenience sample of 63 welding workshops participated in the study. We administered a questionnaire and observed work practices. Sixty-two (98%) workplaces used transformer oil as the coolant in the welding equipment, 60 (95%) claiming that it was the only one available. Sixty-two (98%) did not use any protective measures when refilling coolant oil, while none of them safely disposed of the empty coolant oil containers. Only four (6%) were aware of the possible health effects of PCB-contaminated coolant oil. Health and safety measures in the work places studied were very poor. Coolant oil samples from a sub-sample of 30 welding workshops were tested for PCBs; 19 (63%) were positive. PCB-contaminated coolant oil is widely used by the welders in Kalutara without adequate precautions or safety measures.
