Title: Estimation of current population mean using two-occasion successive sampling with one auxiliary variable Authors: Zoramthanga, R Abstract: In this study, two-occasion successive sampling for ratio-to-regression estimator was used to determine the current estimate of the population mean using only the matched part and one auxiliary variable, which is available on both the occasions. The data used were based on the total number of female workers in villages in Mizoram with the total number of literate female in villages in Mizoram as an auxiliary variables. The data were gotten from Census of India 2001 and 2011. The optimum mean square error of the combined ratio-to-regression and ratio estimator has been compared with (i) the optimum mean square error of the chaintype ratio estimator (ii) mean per unit estimator and (iii) combined estimator when no auxiliary information is used at any occasion. This result showed that the combined ratio-toregression and ratio estimator is more efficient than the other three existing estimators.

Title: Temporal Dynamics of Malaria in Mizoram: A District wise Analysis Authors: Zoramthanga, R Abstract: India is the largest contributor of incidence of malaria cases and related deaths in southeast Asian region. The state of Mizoram is one of the significant contributors of Malaria cases in India. The present study focuses on the transition of malaria cases in the districts of Mizoram from 2011 to 2020. Various indicators including total malaria cases (TMC), Percent of P. falciparum (% Pf), Annual Parasite Index (API), Total positivity Rate (TPR), Annual Blood Examination Rate (ABER), and malarial deaths are processed through descriptive statistics, correlation and ANOVA to understand the disease epidemiology for Mizoram. Results revealed that Lawngtlai, Lunglei and Mamit districts are the top three in average number of malaria cases while Champhai recorded the lowest cases of malaria. Mamit recorded the highest number of malaria related deaths. Age group wise analysis showed that Malaria prevalence is highest in 15+ years of age, and the lowest is in 0-4 years of age. The malarial incidences were highest in the year 2015 for different age groups and sex. Correlation analysis results in significant correlation between TMC vs API, TMC vs TPR, API vs TPR in district Lawngtlai. District wise analysis of Malaria cases showed statistically significant difference (p <0.01) between Lawngtlai and Mamit, Lawngtlai and Saiha, Lawngtlai and Serchhip, Lawngtlai and Serchhip. Findings of this study help in policy interventions and framework. State Vector Borne Diseases Control Programme (Malaria) Mizoram should increase intensified surveillance and monitoring of malaria cases, targeted vector control interventions, improved access to malaria diagnosis and treatments, community-based education and awareness programs.

Title: Association of tobacco use, betel consumption and gastric cancer in Mizoram Abstract: Cancer is a disease that affects the livelihood of humankind for ages. Dietary habit and lifestyle have been attributed to the development of many forms of cancer including gastric cancer. The state of Mizoram located in the northeastern India has been recorded to be a cancer prone area. Most Mizo people indulge in the use of smoke and smokeless tobacco and betel chewing. A study in this high cancer incidence zone is necessary to determine the actual cause of the disease. In this study, we evaluate the influence of tobacco use and betel consumption on gastric cancer. We conclude that individuals with a family history of cancer who consumed betel, smoke and smokeless tobacco have a higher risk of gastric cancer. We also found an association between increased risk of gastric cancer and consumption of betel or sahdah alone and betel with sahdah

Prevalence and predictors of tobacco use among currently married pregnant women in India

Title: Prevalence and predictors of tobacco use among currently married pregnant women in India Authors: Pasupuleti, Samba Siva Rao Abstract: Tobacco use during pregnancy has harmful consequences both to the women and their fetuses. There is a lack of national-level information on the prevalence and predictors of tobacco use among pregnant women in India. This study fills this gap by investigating the prevalence and predictors of tobacco use among currently married pregnant women in India. METHODS Unit level data from the fourth National Family Health Survey, conducted in India during 2015–2016, were used in this study. Logistic regression analyses were performed to identify independent factors associated with tobacco use. RESULTS Our results suggest the prevalence of tobacco use among currently married pregnant women in India is 4.6% (95% CI: 4.3–5.1), and more than 80% of pregnant tobacco users use tobacco in the smokeless form only. Age of woman, region of residence, education level, religion, caste, wealth quintile, frequency of watching television were the independent predictors of tobacco use among currently married pregnant women in India. In general, lower socioeconomic status is positively associated with tobacco use among them. CONCLUSIONS Around 4.6% of pregnant women in India use tobacco, and the smokeless form of tobacco use is predominant among pregnant tobacco users. Socioeconomic disadvantage is positively associated with tobacco use among pregnant women in India. The findings of the present study need to be used to reduce tobacco use among pregnant women in the country by identifying subpopulations at risk, and sensitizing them to the harmful consequences of tobacco use, by offering tobacco cessation services during prenatal checkups.
