Prevalence of Congenital Anomalies in a Secondary Care Hospital in South India: A Cross-Sectional Study.

OBJECTIVE: To study the prevalence and types of congenital anomalies that present at birth in a secondary-level hospital in South India and its contribution to perinatal mortality. MATERIALS AND METHODS: A total of 36,074 births over 10 years, from 2003 to 2013, were studied for the prevalence of gross congenital malformations at birth. It was a descriptive, cross-sectional study using data from the birth register and available medical records. RESULTS: The incidence of birth defects was 12.5 per 1000 live births, with musculoskeletal disorders being the commonest, followed by craniovertebral anomalies. The prevalence of anomalies over the past 10 years has not shown any significant change (p= 0.555). DISCUSSION: The high prevalence of neural tube defects indicates the need for periconceptional folic acid supplementation and early detection of anomalies, which would help in timely management. Detection of musculoskeletal anomalies would help in counseling patients antenatally.

Community perspectives on alcohol use among a tribal population in rural southern India.

BACKGROUND: Alcohol use is common in many cultures. Excessive use of alcohol adversely impacts individuals, families and communities. Medicine, which uses biomedical models and perspectives, views alcohol dependence as a disease. Alcohol use and dependence are complex societal problems, which need to be viewed through multidisciplinary approaches and corrected by adopting intersectoral efforts involving local communities. METHODS: We used qualitative methods such as focus group discussions and in-depth interviews to document perspectives on alcohol use among a tribal community in southern India. We recorded traditional norms, changing patterns of use of alcohol and its consequences for individuals, families and the community. RESULTS: Eight focus group discussions and eleven in-depth interviews were conducted. Though consumption of alcohol is part of the local culture, changes in occupation and availability of alcohol has made its consumption a problem. The introduction and easy availability of Indian-made foreign liquor, which is stronger than the locally brewed variety, in government-run outlets has changed the culture of drinking at festivals to drinking more often. This leads to public fights, domestic violence and increasing mortality and morbidity due to road traffic incidents and ill health. The age of initiation into drinking has decreased. CONCLUSION: The introduction of non-traditional and commercial alcohol use has put a heavy price on tribal and rural people. Community-based interventions targeting young children and adolescents may pay more dividends than pursuing purely medical treatments for problem drinkers.

A community based case control study on determinants of perinatal mortality in a tribal population of southern India.

INTRODUCTION: Perinatal mortality rate has been regarded as an indicator of the quality of prenatal, obstetric and neonatal care in an area, which also reflects the maternal health and socioeconomic environment. The objective of the current study was to identify causes and risk factors for perinatal deaths among the tribal population in Jawadhi Hills, Tamil Nadu, southern India. METHODS: A community-based case control study design was used, where a case was a perinatal death and controls were from a sampling frame of all children who were born alive in the same area ±7 days from the day of birth of the case. The WHO Standard International Verbal Autopsy form was used to arrive at the cause of death. Univariate and multivariate analyses for factors associated with perinatal deaths were done. RESULTS: A total of 40 cases, including 22 early neonatal deaths and 18 stillbirths, and 110 controls were included in the study. Among the perinatal deaths, 40% were born prematurely. Sepsis (17.5%) and birth asphyxias (12.5%) were the major causes of deaths. In the final logistic regression model, parity ≥4 (odds ratio [OR] 5.75 [95% confidence interval (CI) 1.88-17.54]), preterm births (OR 5.62 [95% CI 2.12-16.68]) and time to reach the nearest health facility more than two hours (OR 2.51 [95% CI 1.086.73]) were significantly associated with the perinatal deaths. CONCLUSIONS: Prematurity, poor accessibility and a high parity were significantly associated with perinatal deaths in the tribal population of Jawadhi Hills.

Prevalence & risk factors for soil transmitted helminth infection among school children in south India.

BACKGROUND & OBJECTIVES: Soil-transmitted helminths (STH) are a major public health problem in tropical and sub-tropical countries, affecting the physical growth and cognitive development in school-age children. This study was aimed to assess the prevalence and risk factors of STH infection among school children aged 6 -14 yr in Vellore and Thiruvanamalai districts in south India. METHODS: Children aged 6-14 yr, going to government and government aided schools (n=33, randomly selected) in Vellore and Thiruvanamalai districts were screened to estimate the prevalence of STH, and a case control study was done on a subset to assess the risk factors for the infection. RESULTS: The prevalence of STH was 7.8 per cent, varying widely in schools from 0 to 20.4 per cent, in 3706 screened children. Hookworm (8.4%) rates were high in rural areas, while Ascaris (3.3%) and Trichuris (2.2%) were more prevalent among urban children. Consumption of deworming tablets (OR=0.25, P < 0.01) offered protection, while residing in a field hut (OR=6.73, P=0.02) and unhygienic practices like open air defaecation (OR=5.37, P < 0.01), keeping untrimmed nails (OR=2.53, P=0.01) or eating food fallen on the ground (OR=2.52, P=0.01) were important risk factors for STH infection. INTERPRETATION & CONCLUSIONS: Our study indicated that school children with specific risk factors in the studied area were vulnerable subpopulation with elevated risk of STH infection. Identifying risk factors and dynamics of transmission in vulnerable groups can help to plan for effective prevention strategies.

A proposed methodology of health education for inherited genetic disorders: Bag and Ball technique.

The life-threatening genetic blood disorder, thalassaemia, which causes decreased haemoglobin production, is preventable. Sociocultural determinants and the level of public health awareness must be used to adopt control measures of prevention. Identifying information gaps and educating the community about screening should be a priority, especially in areas with high disease burdens. A relevant health education technique, with which the audience can identify, can effectively bring understanding necessary effectively to sensitise the community. We propose the 'Bag and Ball' method, which includes role-play for health education specifically concerning inherited genetic disorders.

Prevalence and clustering of soil-transmitted helminth infections in a tribal area in southern India.

OBJECTIVES: To estimate the prevalence, spatial patterns and clustering in the distribution of soil-transmitted helminth (STH) infections, and factors associated with hookworm infections in a tribal population in Tamil Nadu, India. METHODS: Cross-sectional study with one-stage cluster sampling of 22 clusters. Demographic and risk factor data and stool samples for microscopic ova/cysts examination were collected from 1237 participants. Geographical information systems mapping assessed spatial patterns of infection. RESULTS: The overall prevalence of STH was 39% (95% CI 36%­42%), with hookworm 38% (95% CI 35­41%) and Ascaris lumbricoides 1.5% (95% CI 0.8­2.2%). No Trichuris trichiura infection was detected. People involved in farming had higher odds of hookworm infection (1.68, 95% CI 1.31­2.17, P < 0.001). In the multiple logistic regression, adults (2.31, 95% CI 1.80­2.96, P < 0.001), people with pet cats (1.55, 95% CI 1.10­2.18, P = 0.011) and people who did not wash their hands with soap after defecation (1.84, 95% CI 1.27­2.67, P = 0.001) had higher odds of hookworm infection, but gender and poor usage of foot wear did not significantly increase risk. Cluster analysis, based on design effect calculation, did not show any clustering of cases among the study population; however, spatial scan statistic detected a significant cluster for hookworm infections in one village. CONCLUSION: Multiple approaches including health education, improving the existing sanitary practices and regular preventive chemotherapy are needed to control the burden of STH in similar endemic areas.

Effect of lock down due to COVID-19 pandemic on the alcohol use and abuse among a tribal community in South India.

Background: Alcohol consumption in the tribal communities is found to be rising, as Indian-made foreign liquor (IMFL) is easily accessible through state-run outlets. During the first coronavirus disease (COVID-19) lockdown, despite IMFL being non-available, there were not any reports of alcohol withdrawal among the tribal men who were enrolled in our substance abuse clinic. Methodology: This is a community-based, mixed-method study to document the changes during the lockdown in the drinking pattern and behavior of families and communities of men who consume alcohol. The quantitative part of the study was done by interviewing 45 alcohol-dependent men and documenting their alcohol use disorders identification test (AUDIT) scores during the lockdown. The qualitative part captured the changes in familial and social behavior. Focused group discussions (FGDs) were conducted among community members and leaders. In-depth interviews (IDs) were done among men with harmful drinking patterns and their spouses. Results: There was a significant reduction in the consumption of IMFL among the men interviewed as depicted by the low mean AUDIT score (16.42, P < 0.001). Trivial withdrawal symptoms were found among them (67%). Around 73.3% could access arrack. The community perceived that arrack was brewed and sold at a higher cost within days of lockdown. Familial conflicts reduced. Certain community leaders and members could proactively curb the brewing and selling of arrack. Conclusion: The study uniquely brought out in depth the information at the individual, familial, and community contexts. It is imperative to develop policies to protect indigenous populations by different rules governing the sales of alcohol.

Hazardous use of alcohol among men in the tribal population of Jawadhi Hills, Tamil Nadu: Nature, prevalence, and risk factors.

BACKGROUND: Worldwide, hazardous use of alcohol is common among many cultures and societies and adversely impacts families and communities, with significant morbidity and mortality. Scheduled Tribes (STs) who are socially deprived and marginalised have higher rates of alcohol use. AIM: We attempted to determine the nature, prevalence, and risk factors associated with hazardous consumption of alcohol in the tribal community. METHODOLOGY: A cross-sectional study was conducted among adult male and permanent residents of Jawadhi hills. A total of 1200 men were interviewed. Study participants were chosen by Probability Proportionate to Size (PPS) sampling method. The questionnaire that documented socio-demographic characteristics and patterns of alcohol use was used. AUDIT tool was used to assess the hazardous use of Alcohol. Data were analysed using SPSS. RESULTS: Majority of the men were middle-aged, married, and were from lower socio-economic strata. A large proportion of men (65%) had a history of alcohol consumption in the last one year using one-year, of whom a quarter showed hazardous use (29%) and another quarter exhibited alcohol dependency (24%). Tobacco use, higher income and local alcohol production were found to be significant risk factors for Hazardous alcohol use. CONCLUSION: Alcohol consumption needs to be treated as a social problem and has to be tackled at the policy level. Population-based interventions, legislation, taxation, policies regarding the manufacture and sale of alcohol, are some of the ways to address this problem.

Perception and awareness of unintentional childhood injuries among primary caregivers of children in Vellore, South India: a community-based cross-sectional study using photo-elicitation method.

OBJECTIVE: We studied the primary caregivers' perception, and further, their awareness of unintentional childhood injuries in south India. METHODS: A cross-sectional study was conducted in the rural block of Kaniyambadi, Vellore, among 300 primary caregivers of children aged between 0 and 14 years. A semi-structured interview was conducted with the primary caregivers using a photo-elicitation method, with a visual depiction of ten injury risky scenarios for a child. Scoring was done to assess the perception of environmental hazards in these scenarios, and further, knowledge on the prevention of these injuries. An independent 't' test was done to elicit differences in mean scores and a multivariate regression analysis was applied to ascertain factors independently associated with the scores. RESULTS: Primary caregivers had adequate perception regarding risks posed to children in scenarios such as climbing trees (96.2%), playing near construction sites (96%), firecrackers (96.4%) and crossing unmanned roads with no traffic signals (94%). Knowledge of prevention was poor however, in the following scenarios: a woman riding a bicycle without safety features, with child pillion sitting behind bare foot and legs hanging by one side (72.6%); a child playing near a construction site (85.9%); and a child playing with plastic bags (88.3%). Overall, educational status of the primary caregiver and socioeconomic status were associated with poorer perception of risks and knowledge about unintentional childhood injuries and their prevention. CONCLUSIONS: Pragmatic community-based childhood interventions incorporated into existing programs, with a special focus on road traffic injuries, burns and suffocation need to be implemented in high-risk settings of rural populations in South India.

Trends of HIV prevalence in rural South India.

BACKGROUND: India, with its large number of migrant workers, had a large number of people affected by HIV. This included antenatal women who are a vulnerable population. The Government of India along with nongovernmental organizations worked on a large number of programs to screen and decrease mother-to-child transmission. This in turn has brought down the prevalence of HIV. MATERIALS AND METHODS: Retrospective analysis of data from the block being provided with healthcare was carried out over a period of 14 years from January 2002 to December 2016. RESULTS: The observed HIV prevalence was 5.9 per 1000 in 2002 and showed a declining trend to 1.2 per 1000 in 2016. CONCLUSION: Consistent work at health education and preventive methods has helped bring down the prevalence of HIV over the years.

Nutritional status, cognitive achievement, and educational attainment of children aged 8-11 in rural South India.

BACKGROUND: Malnutrition among children is one of the most pressing health concerns middle- and low-income countries face today, particularly those in Sub-Saharan Africa and South Asia. Early-life malnutrition has been shown to affect long-term health and income. One hypothesized channel linking early-life malnutrition and long-term outcomes is cognitive development. However, there is limited empirical evidence on the relationship between nutritional status and cognitive achievement in middle childhood. STUDY DESIGN: As part of the South India Community Health Study (SICHS), we collected educational attainment and anthropometric data from 1,194 children in rural Vellore district of Tamil Nadu, India, and assessed their math and reading skills. We analyzed the relationship between continuous and binary anthropometric measures of nutritional status and three measures of cognitive achievement (reading, math, and grade level), adjusting for potential confounders, using a regression framework. RESULTS: Lower height-for-age and weight-for-age and their corresponding binary measures (stunting, underweight) were associated with lower reading scores, lower math scores, and lower grade level, with the exception of the association between weight-for-age and reading, which was marginally significant. A stunted child had one-third of a grade disadvantage compared to a non-stunted counterpart, whereas an underweight child had one-fourth of a grade disadvantage compared to a non-underweight counterpart. Lower BMI-for-age was associated with grade level and marginally associated with lower math scores, and its binary measure (thinness) was marginally associated with lower math scores. CONCLUSIONS: Acute and chronic malnutrition in middle childhood were negatively associated with math scores, reading scores, and educational attainment. Our study provides new evidence that cognitive achievement during middle childhood could be an important mechanism underlying the association between early-life malnutrition and long-term wellbeing.

Diagnostic pathways and direct medical costs incurred by new adult pulmonary tuberculosis patients prior to anti-tuberculosis treatment - Tamil Nadu, India.

BACKGROUND: Tuberculosis (TB) patients face substantial delays prior to treatment initiation, and out of pocket (OOP) expenditures often surpass the economic productivity of the household. We evaluated the pre-diagnostic cost and health seeking behaviour of new adult pulmonary TB patients registered at Primary Health Centres (PHCs) in Vellore district, Tamil Nadu, India. METHODS: This descriptive study, part of a randomised controlled trial conducted in three rural Tuberculosis Units from Dec 2012 to Dec 2015, collected data on number of health facilities, dates of visits prior to the initiation of anti-tuberculosis treatment, and direct OOP medical costs associated with TB diagnosis. Logistic regression analysis examined the factors associated with delays in treatment initiation and OOP expenditures. RESULTS: Of 880 TB patients interviewed, 34.7% presented to public health facilities and 65% patients sought private health facilities as their first point of care. The average monthly individual income was $77.79 (SD 57.14). About 69% incurred some pre-treatment costs at an average of $39.74. Overall, patients experienced a median of 6 days (3-11 IQR) of time to treatment initiation and 21 days (10-30 IQR) of health systems delay. Age ≤ 40 years (aOR: 1.73; CI: 1.22-2.44), diabetes (aOR: 1.63; CI: 1.08-2.44) and first visit to a private health facility (aOR: 17.2; CI: 11.1-26.4) were associated with higher direct OOP medical costs, while age ≤ 40 years (aOR: 0.64; CI: 0.48-0.85) and first visit to private health facility (aOR: 1.79, CI: 1.34-2.39) were associated with health systems delay. CONCLUSION: The majority of rural TB patients registering at PHCs visited private health facilities first and incurred substantial direct OOP medical costs and delays prior to diagnosis and anti-tuberculosis treatment initiation. This study highlights the need for PHCs to be made as the preferred choice for first point of contact, to combat TB more efficiently.

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.

Community perception of child drowning in South India: a qualitative study.

BACKGROUND: World-wide, drowning is one of the leading causes of death in children between 1 and 12 years of age, especially in low- and middle-income countries. AIM: To assess the community's perceptions of the common causes of death in children, the level of awareness of drowning as a major cause and the reasons for the high rate of drowning, and to discuss preventive measures. METHOD: Five focus group discussions were conducted with representatives from five different categories of people in the community. The groups included health aides, extension workers and part-time community health workers in the peripheral health care team of the Department of Community Health, Christian Medical College, Vellore and land owners/village leaders. The data were analysed using content analysis to detect themes and trends. RESULTS: Drowning was not perceived as a major cause of childhood death. Unprotected bodies of water was acknowledged as a reason for the high rate of drowning. The groups suggested some preventive measures including intensive education on the causes of drowning, the introduction of more balwadis (day nurseries) in the villages, and the identification of resources to protect open bodies of water. CONCLUSIONS: There is an urgent need among rural communities to create awareness of the high rate of drowning in children and to motivate and facilitate individuals, communities, organisations and government agencies to make the communities safer for children.

A community health programme in rural Tamil Nadu, India: the need for gender justice for women.

This article highlights the efforts of the Community Health and Development (CHAD) Programme of Christian Medical College to address the issues of gender discrimination and improve the status of women in the Kaniyambadi Block, Vellore, Tamil Nadu, India. The many schemes that are specifically for women and general projects for the community from which women can also benefit represent a multi-pronged approach whose aim is the improvement of women's health, education and employment in the context of community development. However, despite five decades of work with a clear bias in favour of women, the improvement in health and the empowerment of women has lagged behind that achieved by men. We believe this is because the community, with its strong male bias, utilises the health facilities and education and employment programmes more for the benefit of men and boys than women and girls. The article argues for a change of approach, in which gender and women's issues are openly discussed and debated with the community. It would appear that nothing short of social change will bring about an improvement in the health of women and a semblance of gender equality in the region.
