RESUMO
BACKGROUND: Despite acute respiratory infections being a major cause of death among children in developing countries including India, there is a lack of community-based studies that document its burden and aetiology. METHODS: A dynamic cohort of children aged 0-10 years was established in four villages in a north Indian state of Haryana from August 2012 onwards. Trained health workers conducted weekly home visits to screen children for acute respiratory infection (ARI) defined as one of the following: cough, sore throat, nasal congestion, earache/discharge, or breathing difficulty. Nurses clinically assessed these children to grade disease severity based on standard age-specific guidelines into acute upper or lower respiratory infection (AURI or ALRI) and collected nasal/throat swabs for pathogen testing. RESULTS: Our first year results show that ARI incidence in 0-10 years of age was 5.9 (5.8-6.0) per child-year with minimal gender difference, the ALRI incidence in the under-five age group was higher among boys (0.43; 0.39-0.49) as compared to girls (0.31; 0.26-0.35) per child year. Boys had 2.4 times higher ARI-related hospitalization rate as compared to girls. CONCLUSION: ARI impose a significant burden on the children of this cohort. This study platform aims to provide better evidence for prevention and control of pneumonia in developing countries.

BACKGROUND: Relating Information on causes of deaths to implementation of health interventions provides vital information for program planning and evaluation. This paper from Ballabgarh Health and Demographic Surveillance System (HDSS) site in north India looks at temporal trends and gender differentials in the causes of death among under-five children. METHODS: Data on causes of death for 1972-74, 1982-84, 1992-94, 2002-04 were taken from existing HDSS publications and database. Physicians' assigned causes of death were based on narratives by lay health worker till 1994 and later by verbal autopsy. Cause Specific Mortality Fractions (CSMF) and Cause Specific Mortality Rates (CSMR) per 1000 live births were calculated for neonatal (<1 month) and childhood (1-59 months) period. Gender difference was estimated by calculating ratio of CSMR between girls and boys. Available information on coverage of childhood interventions in the HDSS was retrieved and compiled. RESULTS: The CSMF of prematurity and sepsis was 32% and 17.6% during neonatal period in 2002-04. The share of infections in all childhood deaths decreased from 55.2% in 1972-74 to 43.6% in 2002-04. All major causes of mortality (malnutrition, diarrhea and acute lower respiratory infection) except injuries showed a steep decline among children and seem to have plateued in last decade. Most of disease specific public health interventions were launched in mid eighties. . Girls reported significantly higher mortality rates for prematurity (RR 1.52; 95% CI 1.01-2.29); diarrhea (2.29; 1.59 - 3.29), and malnutrition (3.37; 2.05 - 5.53). CONCLUSIONS: The findings of the study point out to the need to move away from disease-specific to a comprehensive approach and to address gender inequity in child survival through socio-behavioural approaches.

OBJECTIVE: To present evaluation of a quality improvement program for Accredited Social Health Activists (ASHAs). METHODS: This community intervention trial was conducted in Ballabgarh, India during 2012-2014 with two Primary Health Center (PHC) areas being the intervention areas and two PHC areas being non-intervention areas receiving standard care. Interventions included two-day training in technical and communication skills of ASHAs followed by supportive supervision in the field. Intervention was evaluated by comparing pre and post training scores, feedback from postnatal mothers and a difference-in-difference (DID) analysis on baseline and endline knowledge-practice survey of recently delivered mothers with 95% confidence intervals. RESULTS: Only 11.1% ASHAs addressed specific barriers for adopting healthy behaviors. Sixty eight (91.8%) ASHAs attended the training after which knowledge improved by 33.3% (p < 0.001). ASHAs in intervention areas were rated by mothers (n = 69) to have better communication skills (81.2% vs. 59.7%, p = 0.005), make more postnatal visits (52.2% vs. 22.2%; p < 0.001), give advice on newborn care (64% vs. 50.5%; p < 0.001) as compared to standard care area ASHAs. Endline survey (n = 1360) showed a significant improvement in frequency of antenatal visits (0.26;0.19-0.33), knowledge about free transport (0.12;0.05-0.18), better cord-care practices (0.15;0.07-0.22), kangaroo mother care (0.19;0.13-0.25), delayed first bath (0.13;0.06-0.20), restrictive handling (0.11;0.06-0.15) and hand-washing (0.19;0.13-0.25). CONCLUSIONS: Quality improvement program can help improve ASHA's performance which in turn can address higher neonatal mortality in India.

Evidence on influenza vaccine effectiveness from low and middle countries (LMICs) is limited due to limited institutional capacities; lack of adequate resources; and lack of interest by ministries of health for influenza vaccine introduction. There are concerns that the highest ethical standards will be compromised during trials in LMICs leading to mistrust of clinical trials. These factors pose regulatory and operational challenges to researchers in these countries. We conducted a community-based vaccine trial to assess the efficacy of live attenuated influenza vaccine and inactivated influenza vaccine in rural north India. Key regulatory challenges included obtaining regulatory approvals, reporting of adverse events, and compensating subjects for trial-related injuries; all of which were required to be completed in a timely fashion. Key operational challenges included obtaining audio-visual consent; maintaining a low attrition rate; and administering vaccines during a narrow time period before the influenza season, and under extreme heat. We overcame these challenges through advanced planning, and sustaining community engagement. We adapted the trial procedures to cope with field conditions by conducting mock vaccine camps; and planned for early morning vaccination to mitigate threats to the cold chain. These lessons may help investigators to confront similar challenges in other LMICs.

OBJECTIVE: To assess sex-specific differentials in child survival from 1992-2011. METHODS: We analyzed data from the electronic database of Health and Demographic Surveillance System (HDSS) site in Ballabgarh in North India. RESULTS: Sex ratio at birth was adverse for girls throughout the study period (821 to 866 girls per 1,000 boys) and was lowest in the period 2004-2006 at 821 girls per 1,000 boys. Overall, under-five mortality rates during the period 1992-2011 remained stagnant due to increasing neonatal mortality rate (9.2 to 27.7 P< 0.001). Mortality rates among girls were consistently and significantly higher than boys during the post-neonatal period (160% to 200% higher) as well as in childhood(160% to 230% higher). CONCLUSIONS: Strategies to address the neonatal mortality and gender differences are required for further reductions in child mortality in India.

INTRODUCTION: Physical activity (PA) is protective against non-communicable diseases and it can reduce premature mortality. However, it is difficult to assess the frequency, duration, type and intensity of PA. The global physical activity questionnaire (GPAQ) has been developed by World Health Organization with the aim of having valid and reliable estimates of PA. The primary aim of this study is to assess the repeatability of the GPAQ instrument and the secondary aim is to validate it against International Physical Activity Questionnaire (IPAQ) and against an objective measure of PA (i.e., using pedometers) in both rural and peri-urban areas of North India. METHODS: A total of 262 subjects were recruited by random selection from Ballabgarh Block of Haryana State in India. For test retest repeatability of GPAQ and IPAQ, the instruments were administered on two occasions separated by at least 3 days. For concurrent validity, both questionnaires were administered in random order and for criterion validity step counters were used. Spearman's correlation coefficient, intra-class correlation (ICC) and Cohen's kappa was used in the analysis. RESULTS: For GPAQ validity, the spearman's Rho ranged from 0.40 to 0.59 and ICC ranged from 0.43 to 0.81 while for IPAQ validity, spearman correlation coefficient ranged from 0.42 to 0.43 and ICC ranged from 0.56 to 0.68. The observed concurrent validity coefficients suggested that both the questionnaires had reasonable agreement (Spearman Rho of >0.90; P < 0.0001; ICC: 0.76-0.91, P < 0.05). CONCLUSIONS: GPAQ is similar to IPAQ in measuring PA and can be used for measurement of PA in community settings.
RESUMO
BACKGROUND: The routine use of verbal autopsy in health-care delivery settings has been limited. Hence, the performance of neonatal and postneonatal verbal autopsy (VA) tools developed at the Comprehensive Rural Health Services Project (CRHSP), Ballabgarh (India), were assessed. METHODS: Short VA tools developed by CRHSP were filled by health workers during their routine house visits while standard VA tools of the International Network of Field Sites with continuous Demographic Evaluation (INDEPTH) were filled by trained research workers for all 143 under-five-children deaths that occurred in 2008. The level of agreement in the cause of death assigned by the two VA tools was assessed by kappa and by comparison of the cause-specific mortality fractions. RESULTS: Among 65 neonatal deaths, the cause specific mortality fraction (CSMF) was 43.1% and 40% for low birthweight, 15.4% and 26.2% for birth asphyxia, and 7.7% and 10.8% for pneumonia by INDEPTH and CRHSP VA tools respectively. In 78 deaths among 29-days to <5-year olds, the CSMF was 29.4% and 26.9% for diarrhoea, and 16.6% each for pneumonia using the INDEPTH and CRHSP VA tools respectively. Kappa for most causes of death was more than 0.8, except for birth asphyxia, which had a kappa of 0.678. CONCLUSIONS: Short VA tools have a satisfactory performance in field settings, which can be used routinely by health workers for filling the gaps in the cause-of-death information in places where medical certification of cause of death is deficient.
RESUMO
BACKGROUND: Most of the standard verbal autopsy tools are long and are used in a research setting. This study aims to compare a short verbal autopsy (VA) tool developed at Ballabgarh, India to be used by health workers for routine mortality surveillance with a standard tool. METHODS: A short VA tool was developed which was used by health workers during their routine house visits while a standard International Network of Field Sites with continuous Demographic Evaluation (INDEPTH) VA tool was filled by trained research workers for all adult deaths that occurred in 2008. The cause-specific mortality fraction using two tools, validity of the Comprehensive Rural Health Services Project (CRHSP) VA tool with INDEPTH VA tool as reference and agreement between the two tools, was compared. RESULTS: The cause-specific mortality fraction was 11.6% and 12% for ischaemic heart disease (IHD), 10.6% and 11.8% for chronic pulmonary obstructive disease (COPD), and 9.4% and 7.3% for tuberculosis, using the INDEPTH and CRHSP VA tool, respectively. 16% and 21% of the deaths could not be classified using the INDEPTH and CRHSP VA tool respectively. The sensitivity of the CRHSP VA tool was 78.5% for IHD, 80% for COPD, 58.3% for tuberculosis, 92.8% for malignant neoplasm and 97.2% for intentional self harm. The kappa between two tools for IHD, COPD, tuberculosis, malignant neoplasm and intentional self harm was 0.754, 0.711, 0.628, 0.876 and 0.892 respectively. CONCLUSION: The short VA tool had a good sensitivity and fair to excellent agreement with the standard tool in different age groups across the major causes of death. It can be used within the routine healthcare delivery framework and can fill the gap in mortality surveillance.

Noncommunicable diseases (NCDs) are emerging as an important public health problem in developing countries. The risk factors for NCDs are initiated during childhood and adolescence. The aim of this review was to assess the effectiveness of school-based interventions for prevention of NCD risk factors (physical inactivity, diet, and tobacco consumption), and identify processes that affect the main outcome. The retrieved studies from 2001 to 2010 were analyzed for their methodological quality (using standard guidelines), settings, intervention components, and main outcomes. The literature search identified 37 studies. The proportion of studies showing a positive result was 83% (10/12) among those that involved family, 87%(7/8) that involved both community and family, and 76% (13/17) that involved school only. Overall, 80% of the studies reported at least some evidence of a positive intervention effect. The current literature search supports the effectiveness of school-based interventions for prevention of risk factors associated with NCDs.

The aim of the study was to evaluate the knowledge of mothers and grandmothers regarding breastfeeding and health-seeking behavior for neonatal sickness in a rural community. A cross-sectional survey, using a triangulation of qualitative (focus group discussion) and quantitative (structured questionnaire) methods was carried out. Although most of the grandmothers and mothers believed in early feeding within 2 h of delivery, they often administered prelacteal feeds such as ghutti and honey. Colostrum was considered beneficial. Most respondents believed that ghutti, water, or both should be given along with breastmilk. Diluted buffalo milk was the preferred choice if supplementation was required. It was thought that weaning should be introduced after 6 months of life. Mothers preferred to give dalia and khichri as the initial weaning food compared to roti and dal water by grandmothers. Both grandmothers and mothers felt that a baby who was playful and not crying excessively was usually healthy. Most of the respondents described the normal pattern of breathing, feeding, urination, and defecation adequately. Most of the grandmothers and mother's felt that by touching forehead and limbs of baby could reliably assess temperature. Refusal to feed was considered as a marker of a sickness by most grandmothers and mothers. However, they also believed that health-seeking for poor feeding could be delayed for 1 day. Respiratory distress was described by the presence of fast respiration, chest retractions, or noisy breathing. Most respondents did not know how to assess cyanosis or seizures. Jaundice was descried as yellowish discoloration of skin, eyes, and urine. Failure to pass urine for 4-6 h bothered most of the respondents. The first response to illness was home remedies. The choice of healthcare was unqualified village practitioners followed by government hospital. Knowledge regarding desirable breastfeeding practices was inadequate and quite a few inappropriate beliefs were widely prevalent. Although knowledge regarding sickness was present, health-seeking from qualified providers was considerably delayed with most respondents preferring village practitioners to government hospitals.

PURPOSE: To develop and test a clinical case definition for identification of generalized tonic-clonic seizures (GTCSs) by community-based health care providers. METHODS: To identify symptoms that can help identify GTCSs, patients with history of a jerky movements or rigidity in any part of the body ever in life were recruited from three sites: the community, secondary care hospital, and tertiary care hospital. These patients were administered a 14-item structured interview schedule focusing on the circumstances surrounding the seizure. Subsequently, a neurologist examined each patient and, based on available investigations, classified them as GTCS or non-GTCS cases. A logistic regression analysis was performed to select symptoms that were to be used for case definition of GTCSs. Validity parameters for the case definition at different cutoff points were calculated in another set of subjects. RESULTS: In total, 339 patients were enrolled in the first phase of the study. The tertiary care hospital contributed the maximal number of GTCS cases, whereas cases of non-GTCS were mainly from the community. At the end of phase I, the questionnaire was shortened from 14 to eight questions based on statistical association and clinical judgment. After phase II, which was conducted among 170 subjects, three variables were found to be significantly related to the presence of GTCSs by logistic regression: absence of stress (13.1; 4.1-41.3), presence of frothing (13.7; 4.0-47.3), and occurrence in sleep (8.3; 2.0-34.9). As a case definition using only three variables did not provide sufficient specificity, three more variables were added based on univariate analysis of the data (incontinence during the episode and unconsciousness) and review of literature (injury during episode). A case definition consisting of giving one point to an affirmative answer for each of the six questions was tested. At a cutoff point of four, sensitivity was 56.9 (47.4-66.0) and specificity, 96.3 (86.2-99.4). Among the 197 GTCS and 26 new non-GTCS patients recruited from hospitals from select SEAR Member Countries, in phase III, the sensitivity of this clinical case definition was 72% and specificity, 100%. A stratified analysis by gender in all the three phases did not show any differences between the sexes. CONCLUSIONS: Based on these criteria, we recommend that all patients with a history of two or more episodes of jerking or rigidity of limbs, having a score of > or =4 in the case definition, be identified as having GTCSs and started on antiepileptic medications. This clinical case definition can be very useful for community-based health care providers to identify and manage cases of GTCSs in the community. This should play a major role in the reduction of treatment gap for epilepsy in developing countries.

OBJECTIVE: To estimate the cost of ambulatory (out-patient) and in-patient pediatric health services for the year 1999 provided by All India Institute of Medical Sciences (AIIMS) at all the three levels-primary, secondary and tertiary level. METHODS: The costing module developed by Children's Vaccines Initiative (CVI) was used. This rapid assessment tool focuses on collection of data at macro level by using key informants like doctors, nursing staff, accountant, store keeper, engineer etc. Cost per beneficiary was estimated separately for in-patients and out-patients and was calculated by dividing the total cost of the services by the number of beneficiaries for the year 1999. For the out-patient, the beneficiaries were the total out-patient attendees and for the in-patient, it was the total pediatric admissions multiplied by mean duration of stay in days. RESULTS: The cost per out-patient visit was INR.20.2 (US0.44 dollars@1US dollars=INR.46) at primary level, higher than INR14.5 (US0.31 dollars) at the secondary level, while at tertiary level it was INR 33.8 (US 0.73 dollars). At the primary and secondary level, non-physician cost was more than the physician cost, and for tertiary level, physician cost was much higher than the other costs. There were no in-patient services at primary level. The cost of in-patient services at secondary level was estimated as INR 419.30 (US 9.1 dollars) per patient per day with a bed occupancy rate of 60%. Two-fifths of the cost was due to nursing and other supportive staff and one fifth due to the doctor costs and overhead costs. The unit cost of INR 928 (US 20.2 dollars) per patient per day incurred at AIIMS with a bed occupancy rate of 100% was almost twice that of secondary level. In contrast to the secondary level, almost half the total costs at tertiary level was due to the doctors costs. CONCLUSIONS: Effective use of resources at lower level of care especially ambulatory care at primary level and inpatient care at secondary level can result in much higher savings for the system and also, the society. These would need to be appropriately strengthened.

OBJECTIVE: To determine whether vaccination against measles in a population with sustained high vaccination coverage and relatively low child mortality reduces overall child mortality. METHODS: In April and May 2000, a population-based, case-control study was conducted at Ballabgarh (an area in rural northern India). Eligible cases were 330 children born between 1 January 1991 and 31 December 1998 who died aged 12-59 months. A programme was used to match 320 controls for age, sex, family size, and area of residence from a birth cohort of 15 578 born during the same time period. FINDINGS: The analysis used 318 matched pairs and suggested that children aged 12-59 months who did not receive measles vaccination in infancy were three times more likely to die than those vaccinated against measles. Children from lower caste households who were not vaccinated in infancy had the highest risk of mortality (odds ratio, 8.9). A 27% increase in child mortality was attributable to failure to vaccinate against measles in the study population. CONCLUSION: Measles vaccine seems to have a non-specific reducing effect on overall child mortality in this population. If true, children in lower castes may reap the greatest gains in survival. The findings should be interpreted with caution because the nutritional status of the children was not recorded and may be a residual confounder. "All-cause mortality" is a potentially useful epidemiological endpoint for future vaccine trials.
