Suicides in young people in rural southern India

Different rates of suicide have been reported in India. In Vellore, southern India, we have noted that the rates of suicides are several fold higher than those reported anywhere in the world, especially in young women. The department of community health at the Christian Medical College, Vellore, has obtained data prospectively on births, deaths, and morbidity in a population of 108?000. We used the verbal autopsy method to assign cause of death. The mortality rates were analysed for 10 years, from 1992 to 2001, for the age-group 10-19 years. Suicides accounted for about a quarter of all deaths in young men and between 50% and 75% of all deaths in young women. The average suicide rate for young women was 148 per 100?000, and for young men 58 per 100?000. We believe that our findings are reliable. The system of surveillance is well established and the verbal autopsy method has been validated. These very high rates of suicide need urgent intervention.

Immunogenicity, reactogenicity and safety of human rotavirus vaccine (RIX4414) in Indian infants.

Aim: This study was undertaken to assess the immunogenicity, reactogenicity and safety of two doses of an oral live-attenuated human rotavirus vaccine, strain RIX4414 (Rotarix™) in an Indian setting. Patients and Methods: Healthy infants (N=363), approximately 8 weeks of age were enrolled to receive two doses of RIX4414 vaccine (n=182) or placebo (n=181) separated by one month. To assess the immune response, blood samples were taken before vaccination and one month post-dose 2 of RIX4414/placebo. Solicited symptoms were collected for 8-days post each dose and safety data was collected throughout the study. Results: The seroconversion rate observed one month post-dose 2 in the RIX4414 group 58.3% [95% CI: 48.7; 67.4] was significantly higher when compared to the placebo group 6.3%; [95% CI: 2.5; 12.5]. The reactogenicity and safety profile was similar for both groups. Conclusions: Two doses of RIX4414 (Rotarix™) were immunogenic, had a good safety profile and were well-tolerated when administered to healthy Indian infants.

Diversity of circulating rotavirus strains in children hospitalized with diarrhea in India, 2005-2009.

BACKGROUND India accounts for 22% of the 453,000 global rotavirus deaths among children <5 years annually. The Indian Rotavirus Strain Surveillance Network provides clinicians and public health partners with valuable rotavirus disease surveillance data. Our analysis offers policy-makers an update on rotavirus disease burden with emphasis on regional shifts in rotavirus strain epidemiology in India. METHODS Children <5 years requiring hospitalization for acute gastroenteritis were selected from 10 representative hospitals in 7 cities throughout India between November 2005 through June 2009. We used a modified World Health Organization protocol for rotavirus surveillance; stool specimens were collected and tested for rotavirus using enzyme immunoassay and reverse-transcription polymerase chain reaction. RESULTS A total of 7285 stool specimens collected were tested for rotavirus, among which 2899 (40%) were positive for rotavirus. Among the 2899 rotavirus detections, a G-type could not be determined for 662 (23%) and more than one G type was detected in 240 (8%). Of 1997 (69%) patients with only one G-type, the common types were G1 (25%), G2 (21%), G9 (13%), and G12 (10%). The proportion of rotavirus infections attributed to G12 infections rose from 8% to 39% in the Northern region and from 8% to 24% in the Western region. CONCLUSIONS This study highlights the large, ongoing burden of rotavirus disease in India, as well as interesting regional shifts in rotavirus strain epidemiology, including an increasing detection of G12 rotavirus strains in some regions. While broad heterotypic protection from rotavirus vaccination is expected based on pre- and post-licensure data from other settings, effectiveness assessments and rotavirus strain monitoring after vaccine introduction will be important.

Infant morbidity in an Indian slum birth cohort

Objective: To establish incidence rates, clinic referrals, hospitalisations, mortality rates and baseline determinants of morbidity among infants in an Indian slum. Design: A community-based birth cohort with twice-weekly surveillance. Setting: Vellore, South India. Subjects: 452 newborns recruited over 18 months, followed through infancy. Main outcome measures: Incidence rates of gastrointestinal illness, respiratory illness, undifferentiated fever, other infections and non-infectious morbidity; rates of community-based diagnoses, clinic visits and hospitalisation; and rate ratios of baseline factors for morbidity. Results: Infants experienced 12 episodes (95% confidence interval (CI) 11 to 13) of illness, spending about one fifth of their infancy with an illness. Respiratory and gastrointestinal symptoms were most common with incidence rates (95% CI) of 7.4 (6.9 to 7.9) and 3.6 (3.3 to 3.9) episodes per child-year. Factors independently associated with a higher incidence of respiratory and gastrointestinal illness were age (3–5 months), male sex, cold/wet season and household involved in beedi work. The rate (95% CI) of hospitalisation, mainly for respiratory and gastrointestinal illness, was 0.28 (0.22 to 0.35) per child-year. Conclusions: The morbidity burden due to respiratory and gastrointestinal illness is high in a South Indian urban slum, with children ill for approximately one fifth of infancy, mainly with respiratory and gastrointestinal illnesses. The risk factors identified were younger age, male sex, cold/wet season and household involvement in beedi work.

Mortality rate and years of life lost from unintentional injury and suicide in South India

We calculated mortality rates and years of life lost because of unintentional injuries and suicides using community based information obtained prospectively over a 7‐year period, from 1998 to 2004, among a rural and peri‐urban population of 108 000 in South India. Per 100 000 population the total mortality rate for unintentional injuries and suicides combined was 137.1, with 54.9 for unintentional injuries and 82.2 for suicides respectively. Hanging and self‐poisoning with pesticides were the preferred means of suicide. Unintentional injuries and suicides resulted in 26.9% of total life years lost over the study period while 18.9% of all deaths in the population were attributable to unintentional injuries and suicides in the same period. The high burden is particularly notable in the 15–29 age group, where up to 70% of years of life lost are due to injury. The burden of injuries reported in this study is significantly higher than the figures reflected in available reports for India and is likely due to the under reporting in routine mortality statistics, particularly of suicides.

Burden of Illness in the First 3 Years of Life in an Indian Slum

The morbidity and mortality in a cohort of 452 children followed up from birth up to 3 years of age, in an urban slum in India, is described. These children were recruited and followed from March 2002 to September 2006. A prospective morbidity survey was established. There were 1162 child-years of follow-up. The average morbidity rate was 11.26 episodes/child-year. Respiratory infections caused 58.3 and diarrheal disease 18.4% of the illnesses. Respiratory illnesses resulted in 48, 67.5 and 50 days of illnesses, and there were 3.6, 1.64 and 1.16 diarrheal episodes per child in the 3 years, respectively. There were five deaths in the cohort in the 3 years of follow-up. Of the 77 drop-outs 44 were contacted for mortality data. The morbidity in the area is high, comparable to other studies. The mortality is low, and is attributed to the facilitated access to care.

Costing of severe pneumonia in hospitalized infants and children aged 2–36 months, at a secondary and tertiary level hospital of a not‐for‐profit organization

Objectives  To determine health care provider cost and household cost of the treatment of severe pneumonia in infants and young children admitted to secondary and tertiary level health care facilities.

Infant Feeding Practices, Dietary Adequacy, and Micronutrient Status Measures in the MAL-ED Study

The overall goal of The Etiology, Risk Factors and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health and Development (MAL-ED) cohort study is to evaluate the roles of repeated enteric infection and poor dietary intakes on the development of malnutrition, poor cognitive development, and diminished immune response. The use of 8 distinct sites for data collection from Latin America, sub-Saharan Africa, and South Asia allow for an examination of these relationships across different environmental contexts. Key to testing study hypotheses is the collection of appropriate data to characterize the dietary intakes and nutritional status of study children from birth through 24 months of age. The focus of the current article is on the collection of data to describe the nature and adequacy of infant feeding, energy and nutrient intakes, and the chosen indicators to capture micronutrient status in children over time.

Self‐harm and self‐poisoning in southern India: choice of poisoning agents and treatment

Objective  To record cases of suicide and attempted suicide among a population of 108 000 people living in a primarily rural area of southern India, with the aim of guiding policies and strategies to restrict access to poisonous compounds at community level.

Early interruption of exclusive breastfeeding: results from the eight-country MAL-ED study

We report the infant feeding experiences in the first month of life for 2,053 infants participating in “Malnutrition and Enteric Infections: Consequences for Child Health and Development” (MAL-ED). Eight sites (in Bangladesh, India, Nepal, Pakistan, Brazil, Peru, South Africa, Tanzania), each followed a cohort of children from birth (by day 17), collecting detailed information on infant feeding practices, diet and illness episodes. Mothers were queried twice weekly regarding health status, breastfeeding and the introduction (or no) of non-breast milk liquids and foods. Here, our goal is to describe the early infant feeding practices in the cohort and evaluate factors associated with termination of exclusive breastfeeding in the first month of life. With data from enrollment to a visit at 28-33 days of life, we characterized exclusive, predominant or partial breastfeeding (using a median of 6-9 visits per child across the sites). Only 6 of 2,053 infants were never breastfed. By one month, the prevalences of exclusive breastfeeding were < 60% in 6 of 8 sites, and of partial breastfeeding (or no) were > 20% in 6 of 8 sites. Logistic regression revealed that prelacteal feeding (given to 4-63% of infants) increased the likelihood of partial breastfeeding (Odds Ratio (OR): 1.48 (95% confidence interval (CI): 1.04, 2.10), as did the withholding of colostrum (2-16% of infants) (OR: 1.63:1.01, 2.62), and being a first-time mother (OR: 1.38:1.10, 1.75). Our results reveal diversity across these sites, but an overall trend of early transition away from exclusive breastfeeding in the first month of life. Interventions which introduce or reinforce the WHO/UNICEF Ten Steps for Successful Breastfeeding are needed in these sites to improve breastfeeding initiation, to reinforce exclusive breastfeeding and delay introduction of non-breast milk foods and/or liquids.
