Impact of vitamin A supplementation through different dosages of red palm oil and retinol palmitate on preschool children.

Red palm oil (5 ml and 10 ml), ground nut oil fortified with 400 and 800 retinol equivalent retinol palmitate, and ground nut oil (5 and 10 ml), were administered to six groups of preschool children (four experimental and two control groups) in randomly assigned balwadis of Ramanathapuram District of Tamil Nadu for a period of 7 months, to monitor the difference in the efficacy of the mode of supplementation and the optimum dose for improving vitamin A status. Results show that red palm oil groups recorded more gain in retinol and beta-carotene levels compared to other dosage groups, and that administration of 10 ml did not offer any substantial improvement over the 5-ml daily dose.

Impact of beta-carotene supplementation through red palm.

A 10-month long feeding trial was conducted to assess the impact of beta-carotene supplementation through red palm oil (RPO) with the focus on vitamin A status, morbidity status and acceptability of an RPO-incorporated noon-meal as a dietary supplement among two cohorts of 409 (experimental) and 346 (control) preschool children in two southern districts of rural Tamil Nadu, selected by stratified random sampling. Information was gathered on ocular symptoms of vitamin A deficiency and anthropometry, and blood samples were drawn at baseline and final rounds for estimation of serum beta-carotene, retinol and tocopherol. Data about Socioeconomic Status (SES) were collected once during the study period, while information on attendance, consumption and morbidity was recorded by preschool teachers. The results showed the following. 1. Significant improvement in the vitamin A status of children in terms of disappearance of Bitot's spots (50.0 per cent) in the experimental group vs. 28.0 per cent in the control group. 2. After feeding of RPO, incidence rate of new Bitot's spots cases was low at 2.13 in the experimental children vs. 4.78 in control children. 3. Marked improvement in the serum beta-carotene levels after 10 months of feeding. 4. RPO is acceptable to children as an edible grade oil as there is no perceptible difference in the consumption pattern between experimental and control children.

High prevalence of type 2 diabetes in an urban settlement in Kerala, India.

BACKGROUND: Prevalence of type 2 or non insulin dependent diabetes mellitus is high among Indians living in India as well as abroad. Prevalence among persons of Indian origin in many countries is greater than that of people of other ethnic extraction. The Indian state of Kerala is distinguished by a high level of achievement in the health sector, characterised by both lower mortality rates and greater density of health care institutions that ensure access to most people. These attributes make the prevalence of diabetes and the pattern of its management in Kerala worth studying. OBJECTIVE: To estimate the prevalence of diabetes among persons 20 years or older in an urban housing settlement in Trivandrum city, the capital of Kerala, as well as study the management of the disease in subjects affected. DESIGN: Cross sectional survey for detecting diabetes and other chronic diseases in all willing residents of an urban housing settlement in Trivandrum, the capital city of Kerala, as part of a preventive campaign against lifestyle diseases. Fasting plasma glucose, serum triglycerides, cholesterol, height, weight and blood pressure were measured, and a detailed questionnaire administered to ascertain previous diabetic status and management. RESULTS: Overall prevalence of type 2 diabetes is 16.3%. In the 30-64 age group, age standardised prevalence is 13.7%. Gender differences in prevalence are negligible. Greater prevalence is associated with advancing age, body mass index above 24.99, sedentary habits, serum total cholesterol > 239, serum triglycerides > 149, hypertension and smoking. Compared to non-diabetics, diabetics have greater mean and range of fasting plasma glucose values (8.87 +/- 3.6 mM/l as against 4.34 +/- 0.53 mM/l). 32 out of 38 diabetics among the subjects (82.4%) were already diagnosed even before the survey; of them, 89% were on medication. 3% of subjects had impaired fasting glucose, or FPG level between 110-125 mg/dl. CONCLUSION: Prevalence of type 2 diabetes among a group of urban residents in Trivandrum city in Kerala is very high. This is associated also with a high detection rate and compliance to treatment.

Nutritional status of children in Kerala.

Nutritional status of children in two poor communities was studied using conventional anthropometric techniques. A total of 944 children, of which 246 boys and 242 girls in coastal area and 213 boys and 249 girls in the non-coastal area formed the study group. With measurements of height and weight, the prevalence of various forms of growth retardation was determined in two communities. Inspite of better food intake, the rural coastal children exhibited poorer nutritional status mainly because of environmental deprivation.

High morbidity and low mortality--the experience of urban preschool children in Kerala.

This study was undertaken to estimate the morbidity pattern in children under 3 years in urban Kerala. Two cohorts of 111 and 74 children were selected from contrasting areas in Trivandrum city, capital of Kerala, by systematic sampling. Morbidity information on each child was gathered for one year through weekly visits and recording of symptoms by trained investigators. The results showed: 1. very high incidence rates of all illness groups studied, with peak incidence being observed in the first 6 months and the lowest in the third year; 2. up to six times greater risk for many disease groups in the more environmentally deprived area; 3. no significant differences in risk between sexes; 4. no seasonal variation. We conclude that despite low infant and child mortality levels, morbidity load in Kerala, for 0-3-year-old children is very high and this is directly related to the quality of the environment.

High risk for coronary heart disease in Thiruvananthapuram city: a study of serum lipids and other risk factors.

There is a trend towards increase in the incidence of coronary heart disease among Indian population. Also, little information is available on the population distribution of serum lipid components and risk factors for coronary heart disease in Kerala, a state fast turning urban. To study the serum lipid profile and the prevalence of other risk factors for coronary heart disease in the residents of an urban housing settlement in Thiruvananthapuram, fasting blood sample was collected from 206 (64%) residents above the age of 19 years and analysed for plasma glucose and various fractions of serum lipids. A detailed questionnaire on the clinical profile and history of the subjects, and measured weights and heights was also administered. Mean serum total cholesterol was 223.7 +/- 45.3 mg/dL; 223.7 +/- 44.9 mg/dL among males and 223.7 +/- 45.8 mg/dL among females. Mean high-density lipoprotein cholesterol was consistently higher in females in all age groups, while mean low-density lipoprotein cholesterol was higher in males till the age group 40-49 after which the pattern was reversed. Mean total cholesterol in the age range 35-64, after age standardisation, was 229.4 mg/dL. Mean serum total cholesterol was higher in this sample when compared to US population, as well as north and west Indian populations. Thirty-two percent subjects were in the highest risk category with serum cholesterol exceeding 239 mg/dL, while in the US population this fraction constituted only 18 percent. Other risk factors such as high blood pressure, obesity, diabetes, sedentary lifestyle and smoking also had a high prevalence in this population. In this settlement of urban residents in Thiruvananthapuram, serum total cholesterol and low-density lipoprotein cholesterol are high. The causes are likely to be dietary. Combined with the high prevalence of other risk factors such as obesity, hypertension, smoking, diabetes and lack of exercise, this situation demands a preventive programme.

Type 2 diabetes in southern Kerala: variation in prevalence among geographic divisions within a region.

BACKGROUND: Numerous surveys carried out in India report the high prevalence of type 2 diabetes. Such studies have not included the population of Kerala. We estimated the prevalence of type 2 diabetes mellitus in Neyyattinkara taluk, Thiruvananthapuram district, Kerala state. METHODS: All panchayat wards in the taluk were grouped into urban, highland, midland or coastal, and one ward from each stratum was randomly selected for the study. All households were listed and adults, 20 years or older, screened for high (> 110 mg/dl) random blood sugar (RBS) by a glucometer test. Those with high RBS were reassessed by a fasting oral glucose tolerance test (OGTT), consisting of initial examination of venous blood for fasting plasma glucose (FPG) values, administration of 75 g of glucose dissolved in distilled water, and examination of venous blood for postprandial plasma glucose (PPPG) exactly 2 hours after the administration of glucose. Diabetes was diagnosed according to the World Health Organization criteria as either FPG > 139 mg/dl, or PPPG > 199 mg/dl, or both. Impaired glucose tolerance (IGT) was diagnosed if PPPG was 140-199 mg/dl. RESULTS: Out of 4988 eligible subjects, 3899 were available for the study, a response rate of 78.2%. Response was highest in the highland area (86.2%), and lowest in the coastal area (73.6%). The overall crude prevalence rate of type 2 diabetes was 5.9%. It was highest in the urban (12.4%), followed by midland (8.1%), highland (5.8%), and coastal (2.5%) regions. Ageing was associated with greater prevalence of type 2 diabetes in all regions and both sexes. Women showed a higher prevalence in the highland and coastal areas and men in the urban and midland areas. When compared to a population with standard age structure suggested by the World Health Organization for international comparisons, prevalence in the age group 30-64 years was found to be 16.9% in the urban, 10.1% in the midland, 6.8% in the highland and 3.6% in the coastal regions, respectively. Overall age-adjusted prevalence of type 2 diabetes in 30-64-year-olds in Neyyattinkara was 9.2% among men, 7.4% among women, and 8.2% for all persons. There was not much difference in prevalence if the American Diabetes Association criteria for diagnosis were used. The prevalence of impaired glucose tolerance was fairly low in this population. Out of 229 diabetics in the sample, 175 (76.5%) were already diagnosed and under treatment, while our survey identified 54 new diabetics (23.5%). CONCLUSION: Though prevalence of type 2 diabetes is high in this population, the detection rate is also high. However, impaired fasting glucose and impaired glucose tolerance are low. The reasons for this need to be elucidated.
