Association of anaemia with indoor air pollution among older Indian adult population: multilevel modelling analysis of nationally representative cross-sectional study.

INTRODUCTION: Anaemia is a disease of public health importance with multi-causal pathways. Previous literature suggests the role of indoor air pollution (IAP) on haemoglobin levels, but this has been studied less due to logistic constraints. A high proportion of the population in developing countries, including India, still depends on unclean fuel, which exacerbates IAP. The objective was to study the association between anaemia and IAP among the older Indian adult population (≥ 45 years) as per gender. METHODS: Our study analysed the nationally representative dataset of the Longitudinal Ageing Study in India (LASI 2017-18, Wave-1). We have documented the association of anaemia (outcome variable) with IAP (explanatory variable). To reduce the confounding effects of demographic and socioeconomic; health related and behavioural covariates; propensity score matching (PSM) was conducted. Nested multilevel regression modelling was conducted. States and union territories were categorised cross tabulated as low, middle and high as per anaemia and IAP exposure. P value < 0.05 was considered statistically significant. SATA version 17 was used for analysis. RESULTS: More than half (52.52%) of the participants were exposed to IAP (male (53.55%) > female (51.63%)). The odds of having anaemia was significantly 1.19 times higher (AOR 1.19 (1.09-1.31)) among participants using unclean/ solid fuel. The adjusted odds were significantly higher among participants exposed to pollution-generating sources (AOR 1.30; 1.18-1.43), and household indoor smoking (AOR 1.17 (1.07-1.29). The odds of having anaemia were significantly higher (AOR 1.26; 1.15-1.38) among participants exposed to IAP, which was higher in males (AOR 1.36; 1.15-1.61) than females (AOR 1.21; 1.08-1.35). Empowered Action Group (EAG) states like Uttar Pradesh, Chhattisgarh, Madhya Pradesh, Bihar had both high anaemia and IAP exposure. CONCLUSION: This study established the positive association of anaemia with indoor air pollution among older Indian adults through a nationally representative large dataset. The association was higher among men. Further research is recommended to understand detailed causation and to establish temporality. It is a high time to implement positive intervention nationally to decrease solid/ unclean fuel usage, vulnerable ventilation, indoor smoking, IAP and health hazards associated with these with more focused actions towards EAG states.

Perception and Practices Regarding Stubble Burning in Rural Community of Haryana.

Background: Agricultural emissions pose significant health risks, especially in countries like India with abundant agricultural waste. This study focuses on understanding stubble burning perceptions and practices in rural National Capital Region to inform targeted interventions for sustainable farming practices and improved public health. Methods and Material: This community-based cross-sectional study was conducted among the randomly selected households of rural Ballabgarh, Haryana. A pre-tested, semi-structured questionnaire was used to obtain information on perception and practices on stubble burning. Data were collected in Epicollect 5 and analyzed in STATA 14. Results: Of the 2000 households approached, 1813 responded with a response rate of 90.7%. Around 53% of the study participants believed that vehicular pollution is the main reason for air pollution, and 90% of them were unaware of the Government schemes related to stop stubble burning and with respect to the practices of stubble disposal. Around 70% of the participants mentioned that respiratory illness is the most severe effect of air pollution. Conclusion: The public was mostly unaware of the government's efforts to reduce stubble burning. Health promotion initiatives must be carried out to raise community knowledge about the programs available to combat stubble burning, therefore decreasing air pollution and its health implications.

Long-Term Kinetics of SARS-CoV-2 Neutralizing and Anti-Receptor Binding Domain Antibodies among Laboratory-Confirmed COVID-19 Cases in Delhi National Capital Region, India: A Prospective, One-Year Follow-Up Study.

Background: This study was conducted with the objective of measuring the neutralizing and anti-receptor binding domain antibody levels against SARS-CoV-2 among laboratory-confirmed COVID-19 cases and exploring its long-term kinetics over a period of 1 year. Methods: One hundred laboratory-confirmed COVID-19 cases were recruited. Serum samples of the participants were collected within three months from the date of the positive COVID-19 report. The participants were prospectively followed up every three months for symptoms and the collection of blood samples for three additional rounds. The presence of anti-SARS-CoV-2 antibodies (IgA, IgG, and IgM antibodies), anti-receptor binding domain antibodies (anti-RBD), and neutralizing antibodies were measured. Findings: Median plaque reduction neutralization test (PRNT) titers showed a rising trend in the first three rounds of follow-up. The quantitative anti-receptor binding domain ELISA (QRBD) values showed a declining trend in the initial three rounds. However, both the PRNT titers and QRBD values showed significantly higher values for the fourth round of follow-up. Total antibody (WANTAI) levels showed an increasing trend in the initial three rounds (statistically significant). Interpretation: Neutralizing antibodies showed an increasing trend. The anti-receptor binding domain antibodies showed a decreasing trend. Neutralizing antibodies and anti-RBD antibodies persisted in the majority.

Cell-Mediated Immunity (CMI) for SARS-CoV-2 Infection Among the General Population of North India: A Cross-Sectional Analysis From a Sub-sample of a Large Sero-Epidemiological Study.

Background Cell-mediated immunity (CMI), or specifically T-cell-mediated immunity, is proven to remain largely preserved against the variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), including Omicron. The persistence of cell-mediated immune response in individuals longitudinally followed up for an extended period remains largely unelucidated. To address this, the current study was planned to study whether the effect of cell-mediated immunity persists after an extended period of convalescence or vaccination. Methods Whole blood specimens of 150 selected participants were collected and tested for Anti-SARS-CoV-2 Interferon-gamma (IFN-γ) response. Ex vivo SARS-CoV-2-specific interferon-gamma Enzyme-linked Immunospot (IFN-γ ELISpot) assay was carried out to determine the levels of virus-specific IFN-γ producing cells in individual samples. Findings Out of all the samples tested for anti-SARS-CoV-2 T-cell-mediated IFN-γ response, 78.4% of samples were positive. The median (interquartile range) spots forming units (SFU) per million levels of SARS-CoV-2-specific IFN-γ producing cells of the vaccinated and diagnosed participants was 336 (138-474) while those who were vaccinated but did not have the disease diagnosis was 18 (0-102); the difference between the groups was statistically significant. Since almost all the participants were vaccinated, a similar pattern of significance was observed when the diagnosed and the never-diagnosed participants were compared, irrespective of their vaccination status. Interpretations Cell-mediated immunity against SARS-CoV-2 persisted, irrespective of age and sex of the participant, for more than six months of previous exposure. Participants who had a history of diagnosed COVID-19 infection had better T-cell response compared to those who had never been diagnosed, in spite of being vaccinated.

Establishing nomogram of blood pressure for late adolescents in India: Secondary analysis of NFHS-4 data.

Background: Hypertension among adolescents is a public health problem, which is going to become more severe given the current obesity epidemic. There is a scarcity of information on the reference range value for blood pressure (BP) cut-off for adolescents. Aim: We aimed to establish BP distribution in adolescents aged 15-19 years by using the nationally representative National Family Health Survey-4 (NFHS-4) data. Materials and Methods: We analyzed the data of 15,936 boys and 1,04,132 girls aged 15-19 years in the NFHS-4 survey. We took the mean of systolic and diastolic BPs. Height for age z scores for each individual was calculated using the WHO Anthro plus. The sampling weight was taken as provided by the demographic and health surveys (DHS) website. Nomograms of systolic and diastolic BPs were made by calculating their 50th, 90th, and 95th percentiles for each age (in months), gender, and height percentile for age categories. Results: Both systolic and diastolic BPs increased with age and height centiles. The BP was higher in boys than girls. The average annual increase in systolic and diastolic BPs was 2.52 and 1.20 mmHg in boys and 0.50 and 0.46 mmHg in girls, respectively, when adjusted for height centiles. Conclusion: This study provides a BP nomogram that can be generalized to all the Indian population. Research is required for the diagnostic performance of this nomogram for the diagnosis of adolescent hypertension.

Assessment of cardiovascular risk using WHO CVD risk prediction chart with respect to hypertension status among Indian population: A secondary analysis of National Family Health Survey (2015-16).

Background: Hypertension, is a crucial risk factor for the development of cardiovascular disease (CVD). Studies assessing the risk of developing CVD among high-risk groups like hypertensives is limited. Aim: The purpose of this study was to find the distribution of CVD risk with respect to hypertension status among Indian adults. Material and Methods: This was a secondary data analysis of NFHS-4 survey data. The distribution of CVD risk among hypertensive participants using 2019 WHO CVD risk prediction charts was compared with normotensive participants among women aged 40-49 years and men in the age group of 40-54 years. Results: The proportion of hypertension was higher among women who consumed alcohol (31.5%) than those who did not (24.3%). The proportion of hypertensives increased with increasing BMI, with maximum proportion among obese women (37.3%). Among women, majority (95.7%) had low CVD risk (<5%) while 4.2% had 5% to <10% CVD risk, and only 0.1% had >10% risk. Among men, those with low CVD risk (<5%) was 65%, those with 5% to <10% CVD risk was 32.3%, 10% to <20% was 2.7%, and a meagre 0.03% had 20 to <30% risk. Conclusion: In the current study, prevalence of hypertension was seen to be increasing with age and was higher in urban residents than rural among both men and women. Both high blood pressure reading during the survey and self-reported hypertension was found to be higher among richest wealth index category. Although risk was higher among hypertensives, self-reported hypertensives who had their blood pressure controlled, had risk similar to normotensives indicating the importance of management of hypertension.

Quality of life of type 2 diabetes mellitus patients attending a tertiary care hospital of Northern India: A cross sectional study.

INTRODUCTION: Diabetes mellitus is a chronic and progressive metabolic disorder. According to the World Health Organization (WHO) there is "an apparent epidemic of diabetes, which is strongly related to lifestyle and economic change." Objective of the study was to assess the quality of life of people living with type 2 diabetes mellitus and factors associated with quality of life. METHODS: A hospital-based cross-sectional study was conducted on 215 patients with diabetes mellitus. Quality of life was assessed using a generic instrument SF 36. The data was analyzed using SPSS, version 24.0. An independent t test and analysis of variance (ANOVA) were used to compare the means of each domain of quality of life within groups of various independent variables. RESULTS: The mean age of respondents was 52.5 ± 11.0 years. The majority (87.4%) of the patients were married, Hindu by religion (88.8%), and belonged to upper socio economic class (28.8%). The mean duration since diagnosis of diabetes was 7.82 ± 6.0 years, and 80.4 percent of patients were on oral hypoglycemic agents. Hypertension was found to be the most common (24.6%) comorbidity. Age, education, socioeconomic status, duration of diabetes, type of treatment, complication of diabetes, comorbidities, and body mass index (BMI) were found to be significantly associated with various domains of SF-36. CONCLUSIONS: Diabetes has an adverse effect on quality of life of patients with diabetes. The most affected domain in male and female patients was vitality domain followed by general health domain of quality of life.

Compliance with iron folic acid (IFA) tablets and associated factors among pregnant women attending ante-natal care clinic at Sub District Hospital, Ballabgarh.

INTRODUCTION: Anemia is a common public health problem among children, adolescent girls, women in reproductive age groups, pregnant and lactating women, with an estimated prevalence of 50.3% among pregnant women according to National Family Health Survey (NFHS) 4. Iron deficiency is regarded as the most common cause of anemia among pregnant women globally and in India. This study was aimed to estimate the prevalence of compliance to iron folic acid (IFA) tablets among pregnant mothers attending ante-natal care (ANC) clinic in a Sub-district hospital (SDH) situated in north India and the various factors associated with non-compliance to IFA tablets. METHODOLOGY: A cross-sectional facility-based study was conducted among pregnant women attending the ANC clinic at SDH, Ballabgarh. A pretested, semi-structured interview schedule was used to obtain socio-demographic data, information related to IFA therapy that they receive, their compliance and the factors that are related to missing of the doses. Data were entered using Epicollect 5 software and Stata version 13.0 was used for statistical analysis. RESULTS: A total of 484 pregnant women were enrolled in our study. More than 3/4th (77.1%) of the pregnant women were compliant to IFA tablet supplement given to them. The compliance was more in the study participants belonging to older age groups, lower socio-economic status and those with hemoglobin levels >11 gm/dl. The most common reason for non-compliance was found to be "forgetfulness" (63.0%) followed by "side effects" (49.5%). CONCLUSION: Compliance with IFA tablets was better among pregnant women who were non anemic and those with good compliance to IFA tablets had better hemoglobin levels.

Estimation of cardiovascular risk in a rural population of Lucknow district using WHO/ISH risk prediction charts.

CONTEXT: Cardiovascular diseases (CVDs) are the number one cause of death globally, with low- and middle-income countries being affected disproportionately. By 2020, it is projected that there will be 25 million deaths from CVD worldwide, 19 million of which would be from middle- and low-income countries. AIMS: The aim of this study was to estimate the 10-year risk of cardiovascular events among adults aged ≥40 years in a rural population of Lucknow district using the World Health Organization (WHO)/International Society of Hypertension (ISH) risk prediction charts for SEAR-D region. SETTINGS AND DESIGN: This was a community based cross-sectional study, conducted from September 2017 to August 2018, in the rural areas of Lucknow district. METHODS AND MATERIAL: This study was conducted on 397 subjects aged ≥40 years. The two sets of the WHO/ISH risk prediction charts, with and without cholesterol, for WHO SEAR-D region were used in the study. STATISTICAL ANALYSIS USED: SPSS, version 23 was used for data analysis. RESULTS: Using the risk assessment tools, with and without cholesterol, 78.5 and 76.8%, respectively, of the study population were in the 10-year cardiovascular risk category of <10% risk, while 11.2 and 10.4%, respectively, were in the category of ≥20% risk. Risk categories were found to be concordant in 86.3% of the population. CONCLUSIONS: The WHO/ISH risk prediction charts can be used at low-cost resource setting as a tool to predict CVD risk among asymptomatic individuals, thus, helping in early detection and prevention of CVDs in resource-scarce settings.

COVID-19 and Menstrual Status: Is Menopause an Independent Risk Factor for SARS Cov-2?

BACKGROUND: COVID-19 has shown a definite association with gender, a predilection for males in terms of morbidity and mortality. The indirect evidence of the protective effect of estrogen has been shown by Channappanavar, in the animal model and Ding T. in a multihospital study from China, suggesting menopause as independent risk factor and estrogen is negatively correlated with severity. OBJECTIVE: Study the clinical profile and outcomes in premenopausal and menopausal. Covid-19-infected women and analyzed the effect of menstrual status on the outcome. MATERIALS AND METHODS: A retrospective cohort study conducted on 147 mild and moderate category COVID-19 females admitted between May and August 2020 using hospital records and telephonic follow-up. Two groups formed based on menstrual status: group-1 (premenopausal/estrogenic) and Group-2 (menopausal/hypoestrogenic). Hospital stay duration was considered as primary, while the category of disease on admission, clinical course, the requirement of oxygen, and mortality and residual symptoms were taken as a secondary outcome to compare the groups. RESULTS: Overall Group-1 had significantly more of mild disease, while Group-2 had moderate cases (39 [76.5%] vs. 14 [14.6%] P < 0.01). Menopausal group has significantly more requirement of oxygen (32 [62.7%] vs. 20 [20.8%]), ventilation (14 [27.5%] vs. 1 [1%]) progression-to-severe disease (23.5% vs. 7.3%) and prolonged hospital stay ([14.1 ± 8.9 vs. 8.6 ± 3.9 days] P < 0.01). However, multivariate logistic regression failed to show a significant association between hospital stay and progression with menopause. Ferritin and residual symptoms found significantly higher in menopausal. CONCLUSIONS: No definite association was found between menopause and COVID-19 outcome with hospital stay duration or disease progression in our study.
