Seasonal variation in prevalence of hypertension: Implications for interpretation.

Objectives: To study seasonal variation in prevalence of hypertension. Materials and Methods: The study was carried out in the year 2006, in Gokulpuri, an urban slum located in eastern part of Delhi. 275 females 18-40 years of age were examined in summer. Blood pressure was measured in two seasons, summer and winter. Nutritional status of each individual was assessed by BMI. Results: The prevalence of hypertension based on SBP was 12.72% in summer which increased to 22.22% in winter. The prevalence of hypertension, using DBP criteria increased to more than double (summer vs. winter, 11.27% vs. 26.59%, P< 0.001). Overall prevalence of hypertension (SBP≥140 or DBP≥90 mm of Hg) was 1.9 times during winter compared to summer (P<0.001). Greater increase in prevalence of hypertension during winter among older females and underweight as well as normal females was observed. Conclusion: Significant increase in prevalence of hypertension during winter compared to summer indicates need for considering this factor while comparing prevalence reported in different studies as well as interpreting the surveillance data based on repeat surveys.

Incidence of summer associated symptoms, host susceptibility and their effect on quality of life among women 18 to 40 years of age in an urban slum of Delhi.

OBJECTIVES: To study whether individual susceptibility plays a role in the occurrence of summer associated symptoms (dizziness, giddiness, fainting and weakness) among women 18-40 years of age and their effect on the quality of life. METHODS: It was a prospective community based study carried out in an urban slum of Delhi as a follow up of an earlier study. All women who had "given symptoms" during summer in the earlier study and a sample of those who were asymptomatic were included in the current study. Both the groups were studied for the occurrence of "given symptoms" and quality of life during next summer and winter using a pre structured questionnaire and WHOQOL-BREF. RESULTS: Incidence of "given symptoms" during summer was more than three times among women who were symptomatic earlier compared to women who were asymptomatic. The incidence of these symptoms was significantly higher among the former across different age groups and BMI categories. Their physical domain of quality of life was also adversely affected. CONCLUSIONS: Continued high incidence of summer associated symptoms with adverse effect on their physical quality of life, among women who were symptomatic earlier too, points to individual susceptibility rather than random occurrence. This aspect requires for further studies.

Problems related to menstruation amongst adolescent girls.

OBJECTIVE: To study the types and frequency of problems related to menstruation in adolescent girls and the effect of these problems on daily routine. METHODS: Girls in the age group 13-19 years who had had menarche for at least one year at the time of study. 198 adolescent girls have been studied. Data was collected by personal interviews on a pre-tested, semi-structured questionnaire. The questions covered menstrual problems, regularity of menses in last three cycles of menstruation and the effect of these problems on the daily routine. Analysis was done using SPSS version 12. Percentages were calculated for drawing inferences. RESULTS: More than a third (35.9%) of the study subjects were in the age group 13-15 years followed by 17-19 years, 15-17 years respectively. Mean age of study participants was calculated to be 16.2 years. Dysmenorrhea (67.2%) was the commonest problem and (63.1%) had one or the other symptoms of Pre-menstrual syndrome (PMS). Other related problems were present in 55.1% of study subjects. Daily routine of 60% girls was affected due to prolonged bed rest, missed social activities/commitments, disturbed sleep and decreased appetite. 17.24% had to miss a class and 25% had to abstain from work. Mothers and friends were the most common source of information on the issue. CONCLUSION: Screen adolescent girls for menstruation related problems and provide them with counseling services and relevant information on possible treatment options. Besides, there is a need to emphasize on designing menstrual health programmes for adolescents.

Clinicoepidemiological profile and predictors of severe illness in young infants (< 60 days) reporting to a hospital in North India.

OBJECTIVES: To describe the clinical and epidemiological profile of young infants reporting to a hospital and assess previously proposed simple clinical signs for their value in enabling health workers to detect young infants with severe illness warranting hospital admission. METHODS: Observational study of infants less than 2 months of age presenting consecutively to a large public hospital in South Delhi who were evaluated by a health worker (nurse), on a standardized list of signs and symptoms, and the ability of these were evaluated against the need for hospital admission which was assessed by an independent pediatrician. RESULTS: Of the 1624 young infants triaged, 878 were enrolled into the study. Of these 100 (11%) were below 7 days of age, for whom the common reasons for seeking care were jaundice (52%), not feeding well (6%) and fever (5%). The remaining 778 (89%) were 7-59 days of age with respiratory symptoms as the main presenting complaints (29.1%). The primary clinical diagnoses in infants with serious illness needing admission to hospital in the age group <7 days (n = 66) were hyperbilirubinemia (56%) and sepsis (21%). In those between 7-27 days of age (n = 60), primary diagnoses were sepsis (27%), pneumonia (13%), diarrhea, dysentery or dehydration (10%), while in the age group 28-59 days of age (n = 47) pneumonia (40%), sepsis (19%) and diarrhea or dehydration (13%) were the common primary diagnoses. Signs that had at least a prevalence of 5% and were strong predictors for all the age categories studied were history of difficult feeding (OR 6.8 for 0-6 days, 15.1 for 2-27 days and 6.2 for 28-59 days age groups), not feeding well on observation (OR 13.7, 27.6 and 20.9 respectively for the 3 age groups), temperature > 37.5C (OR 21.8, 14.6 and 30.0 respectively for the 3 age groups) and respiratory rate > 60 per minute (OR 6.8, 15.1 and 21.0 respectively for the 3 age groups). Additional strong predictors with > 5% prevalence were history of convulsions (OR 7.9, only in 0-6 day age group), lethargy (OR 26.1, only in 7-27 day age group), and history of diarrhea (OR 3.0 for 2-27 days and 2.2 for 28-59 days age groups). CONCLUSIONS: Simple clinical signs are useful in hands of health worker for identifying neonates with serious illness warranting hospital admission. These will be of use in the further development of clinical algorithms for the national integrated management of childhood illnesses.

Practice and knowledge regarding prevention of tetanus among nursing personnel in Delhi.

A cross-sectional study was conducted in Delhi to assess the practices and knowledge regarding tetanus immunization among nursing personnel. Majority of the study subjects had received their last dose of tetanus toxoid injection only after injury and just 4.4% received it to complete the immunization schedule. More than 12% subjects did not know whether they had received any tetanus toxoid injection or not, another 5.5% had their last dose of tetanus toxoid more than ten years back. As many as 20 (22.2%) subjects stated that TT should be given after every injury. Of the remaining 70 subjects only 22.9% correctly knew why TT was not required. Only one third of the subjects knew the indications of anti tetanus serum.

Newborn care practices in an urban slum of Delhi.

BACKGROUND: Despite efforts by government and other agencies, neonatal morbidity and mortality continues to be high in India. Among other reasons, newborn care practices are major contributors for such high rates. AIMS: To find out the newborn care practices including delivery practices, immediate care given after birth and breast-feeding practices in an urban slum of Delhi. SETTINGS AND DESIGN: Community based, cross-sectional survey in a resettlement colony (a type of urban slum). MATERIALS AND METHODS: Semi-structured, pre-tested schedule was used to interview 82 mothers of newborns in the study area. STATISTICAL ANALYSIS: Data was analyzed using Epi - info version 6.04. Fischer exact test and chi2 test were applied. A P value of less than 0.05 was considered significant. RESULTS AND CONCLUSION: More than half i.e. 26 (56.1%) of home deliveries, which were mostly conducted by dais (24, 91.3%) or relatives in 4 (8.7%) of home deliveries. Bathing the baby immediately after birth was commonly practiced in 38 (82.6%) of home deliveries. Finger was used to clean the air passage in most of the home deliveries (29, 63%). About 61% (28) of home delivered newborns were not weighed at birth. Rooming in was practiced in majority of the cases. A few of home delivered neonates (12) were given injection tetanus toxoid by unqualified practitioners. Use of clip, band or sterile thread to tie the cord and no application to the cord was significantly higher in institutional deliveries. Breast milk as the first feed was significantly more in institutional deliveries. There is an urgent need to reorient health care providers and to educate mothers on clean delivery practices and early neonatal care.

Knowledge of general public and health professionals about tetanus immunization.

OBJECTIVE: To study the awareness among general public and health care providers about tetanus immunization in relation to injuries, and their knowledge about tetanus immunization schedules in children, pregnant females and adults. METHODS: It was a cross-sectional study done at a perfect health mela and all the government allopathic health agencies in Delhi. RESULTS: The knowledge of tetanus immunization was poor among general public as well as health care providers. A substantial proportion of them indicated tetanus injection after every injury, which was unwarranted. The knowledge of tetanus immunization schedule for adults was poor among all categories of respondents, though it was comparatively better for pregnant females, but only 75% of doctors and 51.1% of nursing personnel correctly knew the immunization schedule against tetanus in children. CONCLUSION: There is a need to upgrade the level of knowledge among health care providers so as to ensure that schedules of tetanus are followed properly and unnecessary repeated immunizations are avoided and the same knowledge is passed on to the general public also.

National Rural Health Mission--a critical review.

National Rural Health Mission is strategic framework to implement the National Health Policy 2002. The scheme of Accredited Social Health Activist is an improvement over the earlier Community Health Guide Scheme. Integration of various health and family welfare programmes will result in economy and allocation of resources as per needs of the districts. Decentralised planning with the involvement of Panchayati Raj Institutions is likely to make health as people's programme. Converging water supply, sanitation, hygiene and nutrition with health planning is a logical step. The proposal to strenthen institutions of primary health care and Community Health Centres as functional Rural Hospitals alongwith introduction of Indian Public Health Standards and accountability of public health institutions to the public is likely to revolutionise the status of health care in rural India.

Increasing access to cataract surgery in a rural area--a support strategy.

The objectives of the study were to elicit the reasons for not undergoing cataract surgery from those having cataract, aged 50 years and above, in a village community and, develop, implement and assess a support strategy for getting cataract surgery done. The leading reasons identified were monetary constraints (18.8%), transport difficulty (17.4%), lack of awareness about cataract in the eyes (17.4%) and lack of escort (14.5%). Based on the identified reasons, patients were transported in groups to a government eye hospital for free surgery after completion of required pre operative formalities at the village health center itself. Out of 65 eligible individuals, 66.2% underwent surgery. The success of the approach was evident by perceived improvement in vision in 88.4% operated patients, occurrence of only few minor complications and a satisfactory hospital experience being reported by all.

Infant feeding - an evaluation of text and taught.

OBJECTIVE: Study was conducted to 1) assess knowledge of doctors, medical interns and nurses/ANMs regarding exclusive breast-feeding, management of common problems related to breast feeding and appropriate complementary foods 2) review the above aspects in books commonly read by medical and nursing students. METHODS: Cross-sectional study conducted in the department of Community Medicine, Maulana Azad Medical College, New Delhi during a seven-month period on 93 interns, 58 medical officers and 44 nurses/ Auxillary Nurse Midwives (ANMs) with the help of a pre-tested structured multiple choice questionnaire and review of some commonly read books of Pediatrics, Community Medicine and Nursing. RESULTS: The concept of 'exclusive breast-feeding' was clear to most health personnel but the fact that water should also not be given was not clear in the books reviewed. The books also lacked emphasis on management of common lactation problems and this was also seen in the knowledge of the health personnel. CONCLUSION: As inappropriate feeding practices are widely prevalent, knowledge of large proportion of health personnel is incorrect and commonly read books are inadequate on this issue, there is need for greater emphasis on this in books and training sessions.

Knowledge about tetanus immunization among doctors in Delhi.

BACKGROUND: In spite of the clear-cut guidelines regarding tetanus immunization, we have observed that tetanus toxoid injection is often given after injury without considering previous immunization status. One of the reasons for this could be that the doctors themselves are not aware of the correct immunization schedules against tetanus. AIMS: 1. To assess the knowledge about tetanus immunization in relation to injuries among doctors. 2. To assess their knowledge about tetanus immunization schedules in children, pregnant women and adults. SETTING AND DESIGN: It was a cross-sectional study conducted in Delhi. MATERIALS AND METHODS: After complete enlisting of all the government allopathic hospitals and dispensaries, a representative sample (including private practitioners from the nearby area of selected dispensaries) of doctors was selected. All the doctors were personally contacted and information was collected through a pre-structured self-administered proforma. STATISTICAL ANALYSIS: Data was analyzed using a computer and wherever applicable Chi-square test/Z test or Fishers' Exact test was applied. RESULTS AND CONCLUSION: As many as 38.3% of doctors favored tetanus toxoid injection after every injury. The correct knowledge of immunization against tetanus in children, pregnant women and adults was 75%, 90.8% and 35.8% respectively. The knowledge regarding when to give boosters was even poorer. The present study showed that doctors had poor knowledge about tetanus immunization that needs to be improved.

Knowledge regarding tetanus toxoid immunization among persons attending health mela in Delhi.

Although vaccine against tetanus has been in use for more than two decades, often people are not aware of tetanus immunization schedules and its significance in preventing tetanus. The current cross-sectional study was carried out to (1) assess knowledge about tetanus immunization (in relation to injury) among persons attending a health mela and (2) To assess their knowledge about tetanus immunization schedules in children, pregnant women and adults. Every tenth person above 15 years of age, who came to health post in the mela was interviewed. A total of 231 persons attending a health mela in Delhi in October 2003 were interviewed. About two third of them were males. Majority (55%) were graduates or above. Only half of them indicated that they would give tetanus immunization after an injury, two fifth indicated it after animal bite and only one fourth indicated it after burns. Knowledge was higher among females and with higher education. However, knowledge regarding correct immunization schedules, prevention of tetanus by DPT and when to give booster in case of injury after primary immunization was poor. There is need to create greater awareness among people about immunization against tetanus, duration of immunity and disease prevented by it. This is to ensure immunization when it is needed and avoid unnecessary repeated immunization.

Health care seeking pattern of tuberculosis patients attending an urban TB clinic in Delhi.

The study of pattern of health care seeking of tuberculosis patients is important for identification of factors which might influence delayed reporting of tuberculosis cases, especially the open pulmonary cases. Consecutive 301 pulmonary TB patients, belonging to any of the categories under RNTCP, diagnosed at New Delhi Tuberculosis Centre or its sub-centres over a six-month period were assessed for health care seeking pattern. "Delay" was defined as the time over 3 weeks that a case took to report to the area TB facility. 43.2% patients reported to the TB health facility on their own and others were referred by government hospitals (34.9%) and general practitioners (21.9%). Median delay over 3 weeks was 2.69 weeks for all three categories combined, with a significantly higher delay (3.41 weeks) for retreatment cases as compared to new cases (2.13 weeks). No significant differences were observed in health seeking delay in relation to sex, income, literacy status and source of referral and sputum status. Extensive health education activities can reduce this period of delay in health seeking and result in reduction of transmission of tuberculosis to healthy members of the family and community.

Incidence of diarrhoea and some related environmental and behavioural factors in Jhuggis of Delhi.

A total of 6285 persons residing in 1090 households in three Jhuggi clusters of Delhi were studied for incidence of diarrhoea by 2 weeks recall method and environmental and behavioural factors affecting it. Overall incidence of Diarrhoea was 29.1 per thousand persons, and was selectively predominant among under fives (60.2 per thousand). This low incidence of diarrhoea could be attributed to safe drinking water availability and common practice of handwashing by most of the people. But unsafe storage of drinking water at household level (70.5%) and peridomestic open air defaecation by children (22.9%) are potential threat for transmission of the disease.
