The concentrations of Cd, Cr, Cu, Mn, Ni, Pb, and Zn were estimated in hair and nails of urban residents of New Delhi. Particularly, hair levels of Cu and Mn in hypertensive males, Cr and Zn in hypertensive females, and Zn in CHD and diabetic females, and nail levels of Zn in CHD and hypertensive females were significantly lower than controls. Thus, it is observed that there exists some positive correlation between element levels in hair and nails and CHD, hypertension, and diabetes of these subjects.

A community based epidemiological study of coronary heart disease (CHD) was carried out in a random sample of 13723 adults in the age group of 25-64 years in the urban population of Delhi. The electrocardiogram (ECG) of all clinically detected CHD cases and of a sample of 5621 persons (selected on the basis of alternate household screened) without clinical manifestations of CHD, was obtained. Out of 5621 persons labelled as asymptomatic, CHD evidence of Q wave myocardial infarction (MI) was present in 80 ECGs (1.4%). Another 296 ECGs had ST & T changes vide Minnesota Code 4-1-1, 4-1-2, 5-1 and 5-2 acceptable as evidence of probable CHD. The overall prevalence rate of asymptomatic CHD was 6.7% (male 5.6%, female 7.6%). Silent MI was more common in the male patients (1.7% vs 1.1%, p < 0.001). However, ST-T changes were more common in female patients (6.5% vs 3.9%, p < 0.001). The ST-T changes showed a steady factor in asymptomatic CHD cases was hypertension in both sexes (male-45.2%, female-43.5%) p = NS. Obesity was present in 24% of male & 46.1% of female patients (p < 0.001). Family history was found in 20% cases of both sexes. Smoking was recorded in 34.9% male and 10.9% female patients with asymptomatic CHD (p < 0.001).

A community based survey of coronary heart disease (CHD) was carried out in Gujarati families settled in Delhi. The number of adults surveyed in the age group 25-64 yr was 1317. CHD was diagnosed either on the basis of clinical history supported by documentary evidence of treatment in the hospital or at home or on ECG evidence in accordance with the Minnesota Code. The prevalence rate of CHD on clinical history was 25.1 (28.2 in males and 22.4 in females) per 1000 adults (25-64 yr). The prevalence rates were slightly lower in Gujaratis than the general Delhi urban population. The prevalence rate based on both clinical history and ECG criteria was estimated at 66.8 as compared to 96.8/1000 in general urban Delhi population. The risk factors for CHD such as socio-economic status, family history, obesity, smoking, physical activity and hypertension were studied. The mean and 5th, 50th and 95th percentile values of blood lipids were also estimated in CHD patients and compared with the control group. Hypertension ranked the leading risk factor. Prevalence rate of CHD was higher in the upper socioeconomic group. The positive correlation of higher levels of serum lipids e.g., total cholesterol, low density lipoprotein cholesterol (LDL-C) and triglyceride with CHD was confirmed.

In this report we describe 26 pregnancies complicated by hypothyroidism cared for over 6.5 years at AIIMS, New Delhi. In 2 women hypothyroidism was diagnosed during pregnancy; others were diagnosed before pregnancy and continued to receive thyroxine replacement therapy throughout pregnancy. The thyroxine treatment needed readjustment in 7 (26.9%) pregnancies to maintain euthyroidism. Maternal complications included anaemia (23.0%), pregnancy induced hypertension (26.9%), postpartum haemorrhage (7.7%), intrauterine growth retardation (15.4%), postdatism (30.8%), and deficient lactation (19.2%). Perinatal mortality was 3.9%. No case of stillbirth occurred probably because of intensive fetal monitoring and timely termination of pregnancies on evidence of intrauterine fetal compromise. One neonatal death occurred due to fetal thyrotoxicosis. In these cases close surveillance during pregnancy is needed to maintain optimum thyroid hormone concentration, and intensive fetal monitoring is required to achieve a good perinatal outcome.

An epidemic of dengue hemorrhagic fever occurred in Delhi during 1988. A total of 21 pediatric patients with that illness or dengue shock syndrome were evaluated from September-November 1988. All patients had fever, restlessness, ecchymotic spots, and ascites. Pleural effusion occurred in 19 patients (90%) and 18 (86%) exhibited each of the following: vomiting, thrombocytopenia, and hemoconcentration. Hepatomegaly was observed in 15 patients (71%) and splenomegaly in 3 (14%). Titers of hemagglutination inhibition (HI) antibodies against dengue virus type 2 were raised in all 15 cases from whom sera were collected during the acute stage. Convalescent sera from 5 patients had increased titers of HI antibodies to dengue virus type 2. The remaining 10 cases exhibited raised IgM antibody levels against dengue virus type 2. The fatality rate for serologically proven cases was 13% (2 of 15 patients) while for all patients (including those diagnosed clinically [n=6] and serologically [n=15]), it was 33.3% (7 of 21). Patients who survived had no sequelae, except 1 who had transient hypertension which continued for 2 weeks.

The objectives was to assess the determinants of and rates of abortion, stillbirth, and infant mortality for a cohort of pregnant women from slums in New Delhi, Calcutta, and Madras, India and rural slums in Hyderabad, Varanasi, and Chandigarh, India in 1981. The relationship of low birthweight (LBW) and high risk pregnancies to social, environmental, nutritional, cultural, and biological factors was of interest. The results showed variation both between and within urban and rural areas. Rural pregnancy outcome showed fewer LBWs and perinatal and neonatal mortality. Perinatal, neonatal, and infant mortality rates were consistent with prior findings. There was a demonstrated need for prenatal care and referral due to the 10-12% with a poor obstetric history and the significant number with anemia, bleeding, hypertension, toxemia, and urinary tract infections during this pregnancy. Many women were malnourished (body weight 40 kg, height 145 cm, and midarm circumference of 22.5 cm. These women can be identified as high risk. Other risk factors identified were women with disadvantageous personal habits: smoking, alcohol use, tobacco chewing, and working. 10-25% of pregnancies were not registered even though the prenatal clinic was accessible and outreach was provided. 20% completed the recommended number of prenatal visits. 75-85% visited at least once and sometimes more often. Screening for high risk must be done at the 1st visit. Women had strong feelings about the preference for a Dai during delivery and for place of delivery. Poor training of health workers was reflected in the lack of adequate sanitation during the birthing process. Neonatal units were lacking and primary care absent. 10-14% of births were preterm of which 50% occurred at 36 weeks. Multiple regression identified risk factors for fetal and neonatal mortality and LBW as maternal age, preterm birth, maternal anemia, previous preterm or LBW, birth interval, and previous fetal and neonatal mortality. Recommendations are for improving sanitation, hygiene, and water supplies, promoting community awareness of the adverse effects of early marriage and close birth spacing, improving the delivery of health care, allocating health resources based on morality rates, using an intersectoral approach for dealing with the complex social and personal habits adversely affecting childbearing and 7 other suggestions. Existing services and their use are inadequate.

A community based survey of coronary heart disease (CHD) was carried out on a random urban sample of 13,723 adults in the age group 25-64 yr in Delhi, India. CHD was diagnosed either on the basis of clinical history supported by documentary evidence of treatment in a hospital or at home; or on ECG evidence in accordance with the Minnesota Code. The overall prevalence of CHD based on clinical history, was 31.9 (39.5 in males and 25.3 in females) per 1000 adults in this age group. The number of patients with CHD increased with advancing age in both sexes. The total prevalence rate based on both clinical history and ECG criteria (asymptomatic patients with ECG changes of definite myocardial infarction and ST-T changes suggestive of CHD) was estimated as 96.7/1000 adults in this age group. Analysis of information on socio-economic status, family history of CHD, obesity, hypertension and smoking obtained from this sample of 13,723 adults suggested that hypertension had the strongest association with CHD. Obesity, diabetes and family history were also found to be associated with CHD. It should, however, be noted that risk factor assessments in CHD can be done satisfactorily only through incidence studies.

A community based survey for the prevalence of hypertension was carried out on a random urban sample of 13,723 adults in the age group 25-64 yr from the Union Territory of Delhi (India). Hypertension was defined as systolic pressure greater than 160 mm Hg and/or a diastolic pressure greater than 90 mm Hg or a history of current antihypertensive medication. The overall prevalence rate/1000 adults was 127.5 (116.6 in males and 136.8 in females). Mild hypertension (diastolic pressure between 91-104 mm Hg) predominated in the whole group, the proportion decreasing with increasing age in both sexes. Fifty per cent of the hypertensives were aware of their problem, the awareness being slightly higher in females (51.8% versus 46.5%). Approximately 30 per cent of the hypertensives were on medication for high blood pressure. The status control of blood pressure was low in the population, being only 9 per cent, with little difference between the two sexes. The study emphasises the enormity of the problem of hypertension in an urban population in India and poor control of blood pressure achieved in the community.

The prevalence of obesity and its associations were assessed during a community based epidemiological survey of coronary heart disease on a randomised sample of 13,414 adults in the age group 25-64 years living in urban Delhi. Body Mass Index (BMI) > 25 was considered to be the cut off point for defining obesity. By this criterion, the overall prevalence rate of obesity was 27.8%. Obesity was found to be more common in female subjects (Male--21.3%, Female--33.4%, p < 0.001). Obesity was more frequent in male subjects with lower physical activity compared to those doing heavier physical activity (29.3 vs 17.5%, p < 0.001). Physical activity did not influence the prevalence of obesity in females. Hypertension (24.8 vs 8.2%, p < 0.001) coronary heart disease (5.3 vs 2.4%, p < 0.001) and diabetes mellitus (3.2 vs 1.6%, p < 0.001) were more common in the obese than in the non-obese subjects. Hypercholesterolaemia (65.5 vs 53%, p < 0.001) and hypertriglyceridaemia (73.3 vs 61.1%, p < 0.001) were found to be associated with obesity.

A follow-up study of hypertension was carried out among adults in Delhi 3 years after an initial community-based epidemiological survey of the same population. The treatment and the severity status of 1115 out of 1749 individuals with hypertension detected in the initial survey were compared with those observed in the follow-up. The proportion of treated cases with controlled blood pressure rose from 10.8% to 60.8%. Among the cohort of 3611 subjects aged 25-64 years who were normotensive in the initial survey, 132 new cases of hypertension, were detected. The annual incidence of hypertension was the same in men and women (12.2 per 1000). Diabetes and regular alcohol consumption were significant risk factors for hypertension, being present in 13 and 7 cases, respectively. Electrocardiograms (ECGs) were recorded for 871 of the 1115 cases of hypertension. Abnormal ECGs were exhibited by 307 cases (35.2%), of which 24 (2.7%) had had myocardial infarction, 133 (15.3%) had ischaemic ST-T changes, 54 (6.2%) had left ventricular hypertrophy, and 96 (11.0%) had conduction defects and arrhythmias.
