Does secondhand smoke exposure increase the risk of acute respiratory infections among children aged 0-59 months in households that use clean cooking fuel? A cross-sectional study based on 601 509 households in India.

This study examines whether exposure to secondhand smoke (SHS) increases the risk of acute respiratory infections (ARI) among children aged 0-59 months. Study utilized nationally representative data from National Family Health Survey (2015-2016), which adopted two-stage stratified random sampling. Four mutually exclusive groups based on the type of cooking fuel usage and SHS exposure were created. Descriptive statistics and multivariate logistics regression analysis were applied. At the national level, 10.5% prevalence of ARI was reported during 2015-2016. About 47.9% (95%CI 47.7-48.2) of households was exposed to SHS and used solid biomass fuel for cooking. Nearly, 20.7% of households with clean fuel usage was exposed to SHS. Regression analysis suggests that the likelihood of ARI among children who were living in households with solid biomass fuel usage and exposed to SHS was 11% (95%CI 1.06-1.17) greater than children living in households with clean fuel usage with no SHS exposure. Moreover, our results further revealed that the odds of ARI among children living in households with clean fuel but exposed to SHS were 19% (95%CI 1.13-1.25) higher than the children living in the household with no SHS exposure and clean fuel use. Children living in households exposed to SHS are at higher risk of ARI.

Smokeless Tobacco Use among Pregnant Women in India: The Tale of Two Nationally Representative Surveys.

The prevalence of smokeless tobacco (SLT) is pervasive in many Asian countries, including India. SLT use among pregnant women is markedly high, and is considered to be a global concern. Consequently, the associated health effects of SLT consumption on pregnant women and the foetus cause long-term adverse effects. Therefore, this article aims to understand the extent of deviation in SLT use estimates among Indian pregnant women based on two nationally representative surveys and its implications. Responses of 1,403 pregnant women were recorded in the Global Adult Tobacco Survey (GATS 2016-17), whereas 184,641 pregnant women were interviewed in the fourth round of the Demographic and Health Survey or the National Family Health Survey (DHS NFHS 2015-16). Considerable differences in SLT use patterns among pregnant women between the GATS-2 and the NFHS-4 was evident. Overall, the prevalence of SLT use among pregnant women was reported to be higher in GATS than NFHS and this pattern remains similar between age groups of 15 to 34. In the absence of reliable estimates of SLT use among pregnant women, its adverse implications for both reproductive, maternal and child health policies, tobacco control efforts and data quality issues need to be acknowledged and addressed in a targeted manner.

Prevalence of smoking and smokeless tobacco use during breastfeeding: A cross-sectional secondary data analysis based on 0.32 million sample women in 78 low-income and middle-income countries.

Background: Smoking and smokeless tobacco use during the postpartum period is well studied in high-income countries, whereas low-income and middle-income countries (LMICs) lack evidence. Methods: In this cross-sectional study we used data from the Demographic and Health Surveys (DHS) and Multiple Indicator Cluster Surveys (MICS) conducted in 78 LMICs between January 2010 and December 2019 to study tobacco use among 0.32 million sample lactating women. Age-standardized prevalence of smoking and smokeless tobacco use was estimated and presented with a 95% Confidence Interval (CI) for 78 LMICs. Pooled estimates overall and by WHO regions were obtained using random-effects meta-analyses. Country-level and community-level variance to understand contextual factors was also quantified using multilevel modelling. Findings: Pooled prevalence of any tobacco use among breastfeeding women in LMICs was 3.61% (95% CI 3.53-3.70); with the lowest prevalence in regions of the Americas (1.44%, 1.26-1.63) and the highest in the Southeast Asia region (6.13%, 6.0-6.27). The pooled prevalence of tobacco smoking was reported to be 1.16% (1.11-1.21), with the highest prevalence in the Eastern Mediterranean region (4.27%, 3.88-4.67) and the lowest in the African region (0.81%, 0.76-0.86). The pooled prevalence of smokeless tobacco use was reported to be 2.56% (2.49-2.63), with the highest prevalence in the Southeast Asia region (4.92%, 4.80-5.04). Illiterate and poor women in LMICs bore the enormous burden of tobacco use. Interpretation: The prevalence of smoking and smokeless tobacco use among lactating women in LMICs varied considerably across different WHO regions. Considering the cross-sectional design of the study, caution is required while interpreting the results. To improve mothers' and children's health and nutrition outcomes and reduce health inequalities in LMICs, reducing tobacco use through evidence-based interventions is critical. Funding: None.

Social desirability and under-reporting of smokeless tobacco use among reproductive age women: Evidence from National Family Health Survey.

Introduction: This study hypothesises that the presence of a third person during the interaction between the survey investigator and the woman respondent leads to underreporting of smokeless tobacco (SLT) use by Indian women, including pregnant and breastfeeding women. Methods: Cross-sectional data from the National Family Health Survey conducted in 2015-16 was analysed for SLT use among women aged 15-49. Multivariate logistic regression examined the odds of SLT use reporting by women respondents in the presence of their husbands and other male or female adults. Results: SLT use reporting by women significantly varied by the presence of someone during the interview. The analysis shows that the odds of reporting SLT use among women who were neither pregnant nor lactating was 20.6% lower when they were interviewed in the presence of their husbands than when they were interviewed alone. Similarly, compared to those interviewed alone, the odds of women reporting SLT use was 16.5% lower among pregnant and breastfeeding women interviewed in the presence of any adult female. The odds of women under-reporting SLT use were higher in Central and Western India. Conclusions: This study argues that the current survey estimates misconstrue the authentic prevalence of tobacco use among women in India, including pregnant and lactating women. Due to social desirability or the presence of a third person during the survey interview, those respondents who do not report their tobacco use status are also more likely to forego essential support for successful tobacco cessation. Survey methodology must be strengthened to avert the presence of a third person during the interview to ensure better reporting and population health estimates.

Mixed Effect of Alcohol, Smoking, and Smokeless Tobacco Use on Hypertension among Adult Population in India: A Nationally Representative Cross-Sectional Study.

Sporadic evidence is available on the association of consuming multiple substances with the risk of hypertension among adults in India where there is a substantial rise in cases. This study assesses the mutually exclusive and mixed consumption patterns of alcohol, tobacco smoking and smokeless tobacco use and their association with hypertension among the adult population in India. Nationally representative samples of men and women drawn from the National Family and Health Survey (2015-2016) were analyzed. A clinical blood pressure measurement above 140 mmHg (systolic blood pressure) and 90 mmHg (diastolic blood pressure) was considered in the study as hypertension. Association between mutually exclusive categories of alcohol, tobacco smoking and smokeless tobacco and hypertension were examined using multivariate binary logistic regression models. Daily consumption of alcohol among male smokeless tobacco users had the highest likelihood to be hypertensive (OR: 2.32, 95% CI: 1.99-2.71) compared to the no-substance-users. Women who smoked, and those who used any smokeless tobacco with a daily intake of alcohol had 71% (OR: 1.71, 95% CI: 1.14-2.56) and 51% (OR: 1.51, 95% CI: 1.25-1.82) higher probability of being hypertensive compared to the no-substance-users, respectively. In order to curb the burden of hypertension among the population, there is a need for an integrated and more focused intervention addressing the consumption behavior of alcohol and tobacco.

Mapping the triple burden of smoking, smokeless tobacco and alcohol consumption among adults in 28,521 communities across 640 districts of India: A sex-stratified multilevel cross-sectional study.

National estimates on tobacco and alcohol consumption are insufficient to guide policy at the sub-national level. This study assessed the sex-stratified prevalence of different types of smoking and smokeless tobacco and alcohol consumption among adults aged 15-49 using the National Family Health Survey (2015-16) at sub-national administrative units. Three-level logistic regression models were applied to quantify the variation at district- and community-level in smoking and consumption of smokeless tobacco and alcohol. A higher prevalence of smoking, smokeless tobacco and alcohol consumption was observed among men. The study found that the considerable unexplained variations in two different forms of tobacco and alcohol consumption among men attributed to between-population differences at district-level and community-level. The between-population differences were even larger at the district- and community-level in tobacco and alcohol consumption among women. Continious assessment of tobacco and alcohol consumption at lower administrative units and the development of evidence-based localised cessation interventions must be integrated with health policy to reduce disease burden and preventable deaths.

Does violence affect the use of contraception? Identifying the hidden factors from rural India.

PURPOSE: The objective of this study is to investigates the relationship between domestic violence and use of contraception among married women in rural India. DATA: Third round of National Family Health Survey (NFHS-III). METHODOLOGY: Cross tabulation as bivariate analysis and Binary Logistic Regression as multivariate analysis has been employed to fulfill the objective. FINDINGS: The result shows that there are several hidden factors. between physical violence and contraception use. Alternate explanatory variables are significantly affected the use of contraception. With physical violence which reflects that there is a relationship between physical violence and socioeconomic status such as education, awareness, empowerment of women and subsequently the use of contraception. ORIGINALITY/VALUE: The paper throws light on the hidden factors which are obstacle in use of contraception with physical violence. Results of this study have potentially important implications for programs aimed at preventing violence and promoting family planning programs.
