Prevalence of Adult Celiac Disease in India: Regional Variations and Associations.

OBJECTIVES: Although celiac disease (CeD) affects 1% of people in the northern part of India, it is believed to be uncommon in the southern and northeastern parts because of significant differences in dietary pattern and ethnicity. We estimated the prevalence of CeD in these three populations. In a subset, we also investigated differences in the prevalence of HLA-DQ 2/8 allelotype and dietary grain consumption. METHODS: A total of 23,331 healthy adults were sampled from three regions of India-northern (n=6207), northeastern (n=8149), and southern (n=8973)-and screened for CeD using IgA anti-tissue transglutaminase antibody. Positive tests were reconfirmed using a second ELISA. CeD was diagnosed if the second test was positive and these participants were further investigated. A subsample of participants was tested for HLA-DQ2/-DQ8 and underwent detailed dietary evaluation. RESULTS: Age-adjusted prevalence of celiac autoantibodies was 1.23% in northern, 0.87% in northeastern, and 0.10% in southern India (P<0.0001). Prevalence of CeD and latent CeD, respectively, was 8.53/1,000 and 3.70/1,000 in northern, 4.66/1,000 and 3.92/1,000 in northeastern, and 0.11/1,000 and 1.22/1,000 in the southern part. The population prevalence of genes determining HLA-DQ2 and/or -DQ8 expression was 38.1% in northern, 31.4% in northeastern, and 36.4% in southern India. Mean daily wheat intake was highest in northern (455 g) compared with northeastern (37 g) or southern part (25 g), whereas daily rice intake showed an inverse pattern. CONCLUSIONS: CeD and latent CeD were most prevalent in northern India and were the least in southern India. The prevalence correlated with wheat intake and did not reflect differences in the genetic background.

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.

Feasibility, uptake and real-life challenges of a rural cervical and breast cancer screening program in Vellore, Tamil Nadu, South India.

BACKGROUND: Early detection of breast and cervical cancer by organized screening has been found to reduce mortality rates in trials, but documentation of programme results and challenges is rarely done from non-trial settings. This study reports results of a population-based cancer control programme in a rural block in Vellore, Tamil Nadu, population size (116,085), targeting a population of 18,490 women aged 25-60 years, between November 2014 and March 2018. METHODS: Village-based health education sessions were conducted by social workers, using trained volunteers and health workers to motivate eligible women. Screening was done at a secondary level hospital, by trained general physicians using visual inspection with acetic acid and clinical breast examination, followed by colposcopy, radiological imaging (breast) and biopsy as required. RESULTS: A total of 8 volunteers and 17 health workers motivated women for 93 health education and screening sessions, in 46 out of 82 villages. While 1,890/18,490 (10.2 per cent) were screened for breast cancer, 1,783 (9.6 per cent) were screened for cervical cancer, with a yield of 3.4/1,000 for cervical pre-cancer/cancer. The main challenges were creating time for screening activities in a busy secondary hospital and difficulty in ensuring treatment completion of screen-detected cases. CONCLUSIONS: Population-based cancer screening programs can be offered by secondary hospitals that also run primary care services, to increase screening rates. Clear referral systems need to be established, bearing in mind that social factors, especially poor family support, may pose a threat to treatment, in spite of easy availability of cure.

Risk factors for severe acute malnutrition among children aged 6-59 months: A community-based case-control study from Vellore, Southern India.

BACKGROUND: Malnutrition plays an important role in the economic burden of society as well as the country. This study aimed to identify the various risk factors and determinants of severe acute malnutrition (SAM) as defined by WHO growth reference standards in children aged 6 months to 59 months living in Vellore. METHODS: A community-based case-control study matched for age (±2months), gender and location was done among the children of the age group 6- 59 months residing in both rural and urban Vellore. Children of age group 6-59 months with SAM according to WHO definition, i.e., weight for height of less than -3SD with or without nutritional oedema were classified as cases. Children with weight-for-height z-score more than -1 SD and MUAC ≥13.5cms were classified as controls. With 2 controls per case, the required sample size was 54 cases and 108 controls. A questionnaire used to identify the risk factors including dietary intake. Uni-variate and multivariate analysis was done to generate an odds ratio and 95% confidence interval for the risk factors. RESULTS: Majority of the cases 64.8% and 50% of the controls belonged to low SES. After adjusting all confounders, Severe Acute Malnutrition was significantly associated with birth weight <2.499kg [AOR- 8.95 (95% CI: 2.98-26.85)], not exclusively breastfed for 6 months [AOR 4.67 (95% CI: 1.72-12.65)], inadequate calorie intake [AOR 8.09 (95% CI: 3.15-20.82)] and mother being underweight [AOR 6.87 (95% CI: 1.92-24.55)]. CONCLUSION: Programs should be implemented to reduce the poor nutritional status of young girls and women in the reproductive age group. The importance of exclusive breastfeeding for the first six months, the time of weaning and appropriate feeding practice for the child should be emphasized to postnatal mothers during their hospital visits.

Foot care knowledge and practices and the prevalence of peripheral neuropathy among people with diabetes attending a secondary care rural hospital in southern India.

BACKGROUND: Diabetes mellitus is a multifaceted disease and foot ulceration is one of its most common complications. Poor foot care knowledge and practices are important risk factors for foot problems among people with diabetes. AIMS: To assess the knowledge and practices regarding foot care and to estimate the proportion of people with peripheral neuropathy among people with diabetes. SETTINGS AND DESIGN: The cross-sectional study was conducted in 212 consecutive diabetes patients attending the out-patient department of a rural secondary care hospital. MATERIALS AND METHODS: A questionnaire which included demographic details, knowledge questionnaire, and Nottingham assessment of functional foot care was administered. The Michigan Neuropathy Screening Instrument was used to identify peripheral neuropathy. STATISTICAL ANALYSIS USED: Descriptive analysis with frequency distribution for knowledge and practice scores, univariate analysis, and multiple logistic regressions to find significant variables associated with good knowledge and practice scores. RESULTS: About 75% had good knowledge score and 67% had good foot care practice score. Male gender (OR 2.36, 95% CI 1.16-4.79), poor education status (OR 2.40, 95% CI 1.19-4.28), and lesser duration of diabetes (OR 2.24, 95% CI 1.15-4.41) were significantly associated with poor knowledge on foot care. Poor knowledge was associated with poor foot care practices (OR 3.43, 95% CI 1.75-6.72). The prevalence of neuropathy was 47% (95% CI 40.14-53.85) and it was associated with longer duration of the disease (OR 2.18, 95% CI 1.18-4.04). CONCLUSION: There exist deficiencies in knowledge and practices regarding foot care. Male gender, low education, and lesser duration of diabetes are associated with poor knowledge scores. The prevalence of diabetic peripheral neuropathy is high.
