Diabetes Mellitus, Lifestyle and Nutrition in Urban Women: Need for Baseline Knowledge, Attitudes and Practices Guided Programs

Introduction: Fundamental to the success of preventive measures in diabetes mellitus, is disease-related knowledge, attitudes, and practices (KAP). We aimed to assess KAP regarding type 2 diabetes mellitus (T2DM), nutrition and lifestyle in a community-based population of newly diagnosed dysglycemic and normoglycemic women, unaware of their glycemic status at the time of data collection. Methods: Women (2800) aged 30-45 years were screened for dysglycemia using cluster sampling from the Colombo Municipal Council area. All 272 dysglycemic detected through screening and 345 normoglycemic randomly selected from the same screened sample were enrolled. All women were unaware of their glycemic status. The sampling strategy aimed to include adequate numbers of women with altered glycemic status who were unaware of their status at the time of the study. A validated and pretested intervieweradministered questionnaire was used and analyzed using Chi-square test and student’s t-test. Results: KAP on T2DM, nutrition and a healthy lifestyle were poor, particularly knowledge on prediabetes. Some aspects of lifestyle modification were known. Women with a family history compared to those without, had better knowledge (p<0.001) and attitudes (p<0.05), but lower practice scores (p<0.05). Majority of women who found it difficult to resist foods high in fat and sugar, ate while watching television, and a higher proportion of them had a family history (p<0.001). Conclusion: Poor food-related practices observed among those with a family history, despite better knowledge and attitudes indicate a need for targeted intervention. The specific KAP related aspects identified here, can direct future intervention strategies.

Growth parameters at birth of babies born in Gampaha district, Sri Lanka and factors influencing them.

Background: Growth parameters at birth are important for clinical decision-making. In Sri Lanka, the data from the World Health Organization (WHO) Multicentre Growth Reference Study (MGRS) are used to interpret these measurements. Materials and Methods: A descriptive cross-sectional study was conducted between September and October 2010 in hospitals of Gampaha district, Sri Lanka. The weight, length and head circumference of all normal-term babies born in the Gampaha district during this period were measured within 8 h of birth using standard techniques. Measurements were taken by medical graduates trained and supervised by a consultant paediatrician. Socio-demographic data were obtained using an interviewer-administered questionnaire. Results: Of the 2215 babies recruited, 1127 were males. The mean birth weight, mean length and mean head circumference at birth were 2.92 kg, 49.1 and 33.6 cm, respectively. Boys weighed and measured more than girls in all parameters, but the differences were not statistically significant. Growth parameters of babies included in this study deviated from that in the MGRS data. Mean values of MGRS data were between 75th and 90th centiles of this study population. Birth order, family income and maternal education were significantly (P < 0.01) associated with growth parameters. Contrary to common belief, growth parameters continued to increase progressively up to 41 weeks. Maternal age less than 20 years or more than 35 years was negatively associated with birth weight (P < 0.01). Conclusions: Growth parameters of new-born babies deviated significantly from the values of the MGRS data. Growth characteristics of one population may not be applicable to another population due to variations in maternal, genetic and socio-economic factors. Using growth charts not applicable to a population will result in wrong interpretations.

Prevalence and predictors of default with tuberculosis treatment in Sri Lanka.

The objectives of this study were to determine the default rate and predictors for default in patients undergoing antituberculosis treatment. All consenting patients with a confirmed diagnosis of tuberculosis admitted to a unit of the Chest Hospital, Welisara, Sri Lanka from April 2001 to April 2002 were recruited into the study. Personal and follow-up data were recorded on a pre-tested questionnaire and data sheet, respectively. A defaulter was defined as a patient who interrupted treatment for more than two consecutive months before the end of the course of treatment. Of the 892 patients recruited, 770 were new cases and 122 were relapses. The default rates were 10.3% (95% CI: 8.3-12.6) and 30.3% (95% CI: 22.7-38.1) among new cases and retreatment cases, respectively, during the intensive phase of treatment and 10.9% (95% CI:8.7-13.3) and 16.5% (95% CI:9.7-25.5), respectively, during the continuation phase. Ninety percent of new cases and 94% of retreatment cases were sputum positive for acid-fast bacilli at diagnosis. Two hundred five patients (22.9%) defaulted on treatment (95% CI: 20.3-25.8). Using logistic regression analysis, regular smokers (OR = 1.9), smear positive patients who were previous defaulters (OR = 2.4) and patients having involvement of less than 3 zones of the lung on chest x-ray (OR = 0.5) were more likely to default compared to patients who did not smoke regularly, smear positive patients who had relapsed after taking the full course of treatment and patients with less lung involvement. Skilled and unskilled laborers were the most likely occupation to default (OR = 2.03) followed by sales personnel (OR = 2.00), compared to the unemployed or home-bound. A high default rate of 23% was observed among the study participants. Smoking status, occupation, history of treatment compliance of the patient, and extent of lung involvement were predictors for defaulting.

Nutrient intake and growth of adolescents in southern Sri Lanka.

OBJECTIVE: Growth and dietary intake data are essential for formulation of nutritional policies and interventions for children. DESIGN: 945 school children (11-16 years) were subjected to growth assessment and their nutrient intake was determined using the 24-hour dietary recall method on three consecutive days. RESULTS: 21.3% of boys and 21.1% of girls were stunted (-2SD below the median height-for-age). 141 (14.9%) children were both stunted and wasted (-2 SD below the median weight-for-age). Mean body mass index of girls was significantly higher (p < 0.001) than boys at all ages. The mean daily dietary intake of energy was 3.2 (+/- 2.4) MJ, protein 29.1 (+/- 2.1) g, fat 4.5 (+/- 1.1) g, iron 11.5 (+/- 1.0) mg, and zinc 0.8 (+/- 0.7) mg among boys. Among girls, energy intake was 4.2 (+/- 1.8) MJ, protein 29.0 (+/- 2.3) g, fat 4.4 (+/- 1.0) g, iron 11.4 (+/- 1.0) mg, and zinc 0.5 (+/- 0.6) mg. Fat comprised about 4.0% of the daily energy intake. CONCLUSIONS: High rate of growth deficiency and undernutrition among adolescents mandates innovative nutritional intervention strategies. The observed mean intakes of nutrients in the sample showed a worrisome deviation from the recommendations of the dietary guidelines for Sri Lanka.

Hyperhomocysteinaemia in Sri Lankan patients with coronary artery disease.

OBJECTIVE: To determine the association between hyperhomocysteinaemia and coronary artery disease (CAD) in a sample of Sri Lankans. DESIGN: A case control study. SETTING: Asiri Hospital, Kirula Road, Colombo 5, Sri Lanka. SUBJECTS: 105 patients with coronary artery disease and 112 controls. METHOD: Fasting serum homocysteine levels were measured in 105 patients diagnosed as having CAD and in 112 unmatched controls. All patients admitted with clinical, electrocardiographical, biochemical or echocardiographical evidence of CAD were included in the study. Controls were selected from subjects admitted for health screening. RESULTS: 105 patients with CAD and 112 controls (unmatched for age and sex) were studied. A serum homocysteine level in excess of 18.2 mumol/l was considered high. Confounding effects of other conventional risk factors for CAD were controlled using multivariate logical regression analysis. CONCLUSION: Hyperhomocysteinaemia is significantly associated with CAD. Multivariate logistic regression analysis indicated that the association between hyperhomocysteinaemia and CAD was confounded by other risk factors. However, statistical analysis revealed a significant independent association between hyperhomocysteinaemia and CAD (adjusted odds ratio = 2.881).
