Social, cultural and economical determinants of diabetes mellitus in Kalutara district, Sri Lanka: a cross sectional descriptive study

IntroductionSri Lanka is a country that is expected to face a high burden of diabetes mellitus (DM). There is a paucity of data on social and demographic determinants of DM, especially in the plantation sector.AimsTo describe social and economic correlates and inequalities of DM in Kalutara District.MethodsA cross sectional descriptive study was carried out among adults over the age of 35 years. A sample of 1300 individuals was selected using stratified random cluster sampling method from 65 Grama Niladari Divisions (GND), which were representative of urban, rural and plantation sectors. Twenty households were randomly selected from each division and one adult was randomly selected from each household. Data were collected using a pre-tested questionnaire. Fasting plasma blood sugar of ≥126mg/dl was used to define DM. Significance of prevalence of diseases and risk factors across different socio-economic strata were determined by chi square test for trend.ResultsOf 1234 adults who were screened (628 males), 202 (14.7%) had DM. Higher DM proportions (16.1%) were seen in the highest income quintile and in those educated up to Advanced Levels (AL) and above (17.3%). Prevalence in the urban, rural and plantation sectors were 23.6%, 15.5% and 8.5% respectively. Prevalence among Sinhalese, Tamils and Muslims were 14.4%, 29.0% and 20.0% respectively. There was a gradient in prevalence according to the unsatisfactory basic needs index of the GND with the highest proportion (20.7%) observed in the richest GND. The highest social status quintile demonstrated the highest proportion (17.4%) with diabetes mellitus.ConclusionThere is a higher prevalence of diabetes mellitus in the more affluent and educated segments of society. There is also a higher prevalence among urban compared to rural and estates. Sri Lanka is in an early stage of the epidemic where the wealthy people are at a higher risk of DM.

Migration of Sri Lankan medical specialists

BackgroundThe migration of health-care workers contributes to the shortage of health-care workers in many developing countries. This paper aims to describe the migration of medical specialists from Sri Lanka and to discuss the successes and failures of strategies to retain them.MethodsThis paper presents data on all trainees who have left Sri Lanka for postgraduate training through the Post Graduate Institute of Medicine, University of Colombo, from April 1980 to June 2009. In addition, confidential interviews were conducted with 30 specialists who returned following foreign training within the last 5 years and 5 specialists who opted to migrate to foreign countries.ResultsFrom a total of 1,915 specialists who left Sri Lanka for training, 215 (11%) have not returned or have left the country without completing the specified bond period. The majority (53%) migrated to Australia. Of the specialists who left before completion of the bond period, 148 (68.8%) have settled or have started settling the bond. All participants identified foreign training as beneficial for their career. The top reasons for staying in Sri Lanka were: job security, income from private practice, proximity to family and a culturally appropriate environment. The top reasons for migration were: better quality of life, having to work in rural parts of Sri Lanka, career development and social security.ConclusionsThis paper attempts to discuss the reasons for the low rates of emigration of specialists from Sri Lanka. Determining the reasons for retaining these specialists may be useful in designing health systems and postgraduate programs in developing countries with high rates of emigration of specialists.

A cross sectional survey on social, cultural and economic determinants of obesity in a low middle income setting

IntroductionObesity is an increasing problem in South Asian countries and Sri Lanka is no exception. The socioeconomic determinants of obesity in Sri Lanka, and in neighbouring countries are inadequately described. Aim was to describe social, cultural and economic determinants of obesity in a representative sample from Kalutara District in Sri Lanka.MethodsThis was a cross sectional descriptive study conducted among adults aged 35–64 years. A representative sample was selected using stratified random cluster sampling method from urban, rural and plantation sectors of Kalutara District. Data were collected using a pre-tested questionnaire. A body mass index of 23.01 kg/m2-27.50 kg/m2 was considered as overweight and ≥27.51 kg/m2 as obese. Waist circumference (WC) of ≥ 90 cm and ≥80 cm was regarded as high for men and women respectively. Significance of prevalence of obesity categories across different socio-economic strata was determined by chi square test for trend.ResultsOf 1234 adults who were screened, age and sex adjusted prevalence of overweight, obesity and abdominal obesity (high WC) were 33.2% (male 27.3%/female 38.7%), 14.3% (male 9.2%/female 19.2%) and 33.6% (male 17.7%/female 49.0%) respectively. The Muslims had the highest prevalence of all three obesity categories. Sector, education, social status quintiles and area level deprivation categories show a non linear social gradient while income shows a linear social gradient in all obesity categories, mean BMI and mean WC. The differences observed for mean BMI and mean WC between the lowest and highest socioeconomic groups were statistically significant.ConclusionThere is a social gradient in all three obesity categories with higher prevalence observed in the more educated, urban, high income and high social status segments of society. The higher socioeconomic groups are still at a higher risk of all types of obesity despite other public health indicators such as maternal and infant mortality displaying an established social gradient.

Sharps injuries among medical students in the faculty of medicine, Colombo, Sri Lanka

IntroductionMedical students undertake clinical procedures which carry a risk of sharps injuries exposing them to bloodborne infections.ObjectivesTo study the prevalence and correlates of sharps injuries among 4th-year medical students in the Faculty of Medicine, University of Colombo, Sri Lanka.Materials and MethodsThe survey was conducted among 4th-year medical students to find out the incidence of injuries during high-risk procedures, associated factors and practice and perceptions regarding standard precautions. A self-administered questionnaire was administered to a batch of 197 4th-year medical students.ResultsA total of 168 medical students responded. One or more injury was experienced by 95% (N = 159) of the students. The majority (89%) occurred during suturing; 23% during venipuncture and 14% while assisting in deliveries. Most of the incidents (49%) occurred during Obstetrics and Gynecology attachments. Recapping needles led to 8.6% of the injuries. Thirty-five percent of students believed they were inadequately protected. In this group, adequate protection was not available in 21% of the incidences and 24% thought protection was not needed. Following the injury, 47% completely ignored the event and only 5.7% followed the accepted post-exposure management. Only 34% of the students knew about post-exposure management at the time of the incident. Only 15% stated that their knowledge regarding prevention and management was adequate. The majority (97%) believed that curriculum should put more emphasis on improving the knowledge and practice regarding sharps injuries.ConclusionsThe incidence of sharps injuries was high in this setting. Safer methods of suturing should be taught and practiced. The practice of standard precautions and post-injury management should be taught.

Tobacco Smoking Among School Children in Colombo District, Sri Lanka:

Tobacco smoking is an important problem among schoolchildren. The authors studied the patterns of tobacco smoking among schoolchildren in Colombo, Sri Lanka, using a self-administered questionnaire. Multistaged stratified random sampling was used to select 6000 students. Response rate was 90.7% (5446), out of which 53.4% were males. Prevalence rates for males and females, respectively, were as follows: having smoked at least 1 complete cigarette: 27.0% and 13.3%, smoked more than 100 cigarettes: 2.3% and 0.3%, daily smoking: 1.8% and 0.2%. Mean age of starting to smoke was 14.16 years. The tobacco products most used were cigarettes (91.5%) and bidis (3.8%). In univariate analysis, male gender, parental smoking, studying non-science subjects, peer smoking, and participating in sports were significantly associated with smoking of at least 1 complete cigarette (P < .05). In multivariate analysis, the most significant correlates were having close friends (odds ratio = 3.29, confidence interval = 2.47-4.37) or parents who smoked (odds ratio = 1.86, confidence interval = 1.28-2.71). Female smoking has increased from previously reported values. These high-risk groups can be targets for preventive programs.

A survey on socioeconomic determinants of diabetes mellitus management in a lower middle income setting

BackgroundInformation on socioeconomic determinants in the management of diabetes mellitus is scarce in lower middle income countries. The aim of this study is to describe the socioeconomic determinants of management and complications of diabetes mellitus in a lower middle income setting.MethodsCross sectional descriptive study on a stratified random sample of 1300 individuals was conducted by an interviewer administered questionnaire, clinical examinations and blood investigations. A single fasting venous blood sugar of ≥126 mg/dl was considered diagnostic of new diabetics and poor control of diabetes mellitus as HbA1C > 6.5 %.ResultsThere were 202 (14.7 %) with diabetes mellitus. Poor control was seen in 130 (90.7 %) while 71 (49.6 %) were not on regular treatment. Highest proportions of poor control and not on regular medication were observed in estate sector, poorest social status category and poorest geographical area. The annual HbA1C, microalbuminuria, retinal and neuropathy examination were performed in less than 6.0 %. Social gradient not observed in the management lapses. Most (76.6 %) had accessed private sector while those in estate (58.1 %) accessed the state system.The microvascular complications of retinopathy, neuropathy and microalbuminuria observed in 11.1 %, 79.3 % and 54.5 % respectively. Among the macrovascular diseases, angina, ischaemic heart disease and peripheral arterial disease seen in 15.5 %, 15.7 % and 5.5 % respectively. These complications do not show a social gradient.ConclusionsDiabetes mellitus patients, irrespective of their socioeconomic status, are poorly managed and have high rates of complications. Most depend on the private healthcare system with overall poor access to care in the estate sector.

Use of illicit substances among schoolchildren in Colombo District, Sri Lanka

ABSTRACT Objective: This study aimed to understand the usage patterns and correlates of illicit drug use among schoolchildren in Colombo district, Sri Lanka. Methods: A cross-sectional study was carried out among grade 10 and 12 students using a self-administered questionnaire. Results: From the 6000 students selected, 5353(89.22%) responded. Betel chewing with tobacco was seen in 28.48% males and 10.44% females. Substances such as Barbul, Madana Modaka, and cough syrups that are not established as illicit drugs were used as psychoactive substances. Ingredients of some of these compounds are not fully understood or regulated. Prevalence of cannabis use was 3.85% in males and 0.24% in females. Studying nonscience subjects for Advanced Level, doing sports, low academic performance, and peer smoking significantly increased the odds of using one or more substances (P < .05). Conclusions: Many types of illicit substances were used by schoolchildren. More strategies to prevent further aggravation of these behaviors are needed. Constituents of some compounds are not understood and need further evaluation. Recognized high-risk groups can be targets for preventive and cessation programs.
