Prevalence of psychological morbidities among general population, healthcare workers and COVID-19 patients amidst the COVID-19 pandemic: A systematic review and meta-analysis

This review was done to synthesize the existing evidence on the prevalence of various psychological morbidities among general public, healthcare workers and COVID-19 patients amidst this pandemic situation. Systematic searches were conducted in various databases and search engines such as Medline, Chinese national knowledge infrastructure, Cochrane library, ScienceDirect, and Google Scholar from inception until 22 April 2020. Newcastle Ottawa scale was used to assess the quality of included studies. We carried out a meta-analysis with random-effects model and reported pooled prevalence with 95% confidence intervals (CIs).A total of 50 studies were included in the review. Only seven studies (14%) had low risk of bias. Pooled prevalence rate of psychological morbidities includes poor sleep quality (40%), stress (34%), psychological distress (34%), insomnia (30%), post-traumatic stress symptoms (27%), anxiety (26%), depression (26%). Pooled prevalence rate of psychological morbidities with respect to impact of event due to COVID-19 pandemic was 44% (95%CI-42% to 47%). The burden of these psychological morbidities was highest among the COVID-19 patients followed by healthcare workers and general population.

Diagnostic accuracy of various forms of geriatric depression scale for screening of depression among older adults: Systematic review and meta-analysis

OBJECTIVES

Depression is under-reported and under-identified by the healthcare professionals. Geriatric depression scale (GDS) is one of the most commonly used instruments for screening the older adults for depression. The current review was done to determine the diagnostic accuracy of various forms of GDS for screening of depression among older adults.

METHODS

We conducted systematic search in various databases like Medline, Cochrane library, Sciencedirect and Google Scholar from inception till May 2019. Quality of trials was assessed by Quality Assessment of Diagnostic Accuracy Studies-2 tool. We performed bivariate meta-analysis to obtain the pooled sensitivity, specificity, positive, negative likelihood ratio and diagnostic odds ratio for each of the GDS forms.

RESULTS

Totally 53 studies with 17,018 participants were included in the review. We found the pooled sensitivity and specificity of GDS 30 to be 82 % and 76 % with near higher diagnostic accuracy (AUC = 0.85). GDS 15 had pooled sensitivity and specificity of 86 % and 79 % with higher diagnostic accuracy (AUC = 0.90). GDS 10 had pooled sensitivity and specificity of 87 % and 75 % with AUC = 0.83. Our study found GDS 4 to have sensitivity of 74 % with specificity of 71 %. All the four forms of GDS belonged to right lower quadrant of LR scatter-gram indicating neither confirmation nor exclusion.

CONCLUSION

Current study found that all the forms of GDS are highly useful for detecting depression among elderly with higher sensitivity and specificity. The diagnostic performance was much better for shorter forms of GDS such as GDS 15 and GDS 10 when compared to GDS 30.

Prevalence of metabolic syndrome among adult population in India: A systematic review and meta-analysis

OBJECTIVE

This review was done to determine the prevalence of metabolic syndrome (MS) among adult general population in India. We also wanted to find the gender, setting, and region-wide distribution of MS in India.

METHODS

We conducted systematic searches in various databases including Medline, ScienceDirect, Cochrane library and Google Scholar from inception until August 2019. We included studies conducted in India reporting the prevalence of MS among adults aged 18 years or more. We used the Newcastle Ottawa scale to assess the quality of included studies. We carried out a meta-analysis with random-effects model and reported pooled prevalence with 95% confidence intervals (CIs). We used the Funnel plot to assess publication biases.

RESULTS

In total, we analysed 113 data from 111 studies with 133,926 participants. Majority of the included studies (76 out of 111) had low risk of bias. We found significant heterogeneity among the included studies (p<0.001). We also found a symmetrical funnel plot indicating an absence of publication bias. The prevalence of MS among adult population in India was 30% (95%CI: 28%-33%). There was a steady increase in the burden across the age groups from 13% (18-29 years group) to 50% (50-59 years). We also found that people living in urban areas (32%; 95%CI: 29%-36%) had higher prevalence when compared to tribal (28%; 95%CI: 21%-36%) or rural adults (22%; 95%CI: 20%-25%). Gender distribution of MS showed that the females had higher prevalence (35%; 95%CI: 31%-38%) when compared to males 26% (95%CI: 22%-29%).

CONCLUSION

Almost one in three adults in India suffer from MS. Females, people living in urban areas and in northeast region had higher prevalence of MS. Development and implementation of policies and protocols for the screening of MS would enable us in early diagnosis and treatment with special focus towards the vulnerable and high-risk groups.

Effectiveness of Financial Incentives in Achieving UNAID Fast-Track 90-90-90 and 95-95-95 Target of HIV Care Continuum: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Financial incentives influence behavioural changes and the current review was done to assess the effectiveness of this intervention in improving HIV care continuum. We conducted systematic searches in MEDLINE, Cochrane library, ScienceDirect and Google Scholar from inception until July 2019. We carried out a meta-analysis with random-effects model quantifying inconsistency (I2) for heterogeneity and reported pooled Risk Ratios (RR) with 95% confidence intervals (CIs). A total of 22 studies with 38,119 participants were included. All the six outcomes showed better results in financial incentive arm compared to standard care with statistical significance in three outcomes-HIV testing uptake (pooled RR: 2.42; 95%CI 1.06-5.54; I2 = 100%), antiretroviral therapy (ART) adherence (pooled RR: 1.30; 95%CI 1.13-1.50; I2 = 44%), and continuity in care (pooled RR: 1.24; 95%CI 1.09-1.41; I2 = 86%). To summarize, financial incentives can be helpful in improving the uptake of HIV testing, ART adherence and continuity of care while it was better for achieving viral load suppression among studies conducted in high-income countries.

Effectiveness of peer led intervention in improvement of clinical outcomes among diabetes mellitus and hypertension patients-A systematic review and meta-analysis

Peer-led intervention allows the patients to develop knowledge, skills and confidence in managing their own conditions. Hence this review was done to assess the effectiveness of peer-led intervention in improving the clinical outcomes of DM and HTN patients. We conducted systematic search in Medline, CENTRAL, Sciencedirect and Google-Scholar from inception till May 2018 and retrieved 3654 citations. Meta-analysis was performed using random-effects model and pooled mean difference (MD) was reported with 95% CI. Publication bias was assessed using Egger's test. 29 trials (26 DM and 3 HTN) with 6363 participants were included. There was positive effect of peer led intervention on DM and HTN with pooled MD of -0.28% [95%CI: -0.45 to -0.11] and -7.52mmHg [95%CI: -14.39 to -0.66]. There was significant heterogeneity and publication bias in both DM and HTN trials. Sensitivity analysis showed only little improvement in the final estimate. Peer support intervention is effective and causes statistically significant reduction in HbA1C and systolic blood pressure among DM and HTN patients.

Association between Indoor Air Pollution and Cognitive Impairment among Adults in Rural Puducherry, South India

BACKGROUND

Recent evidences showed that outdoor air pollution had significant influence on cognitive functioning of adults. However, little is known regarding the association of indoor air pollution with cognitive dysfunction. Hence, the current study was done to assess the association between indoor air pollution and cognitive impairment among adults in rural Puducherry.

METHODOLOGY

A community-based cross-sectional study was done among 295 adults residing in rural field practice area of tertiary care institute in Puducherry during February and March 2018. Information regarding sociodemographic profile and household was collected using pretested semi-structured questionnaire. Mini-Mental State Examination was done to assess cognitive function. We calculated adjusted prevalence ratios (aPR) to identify the factors associated with cognitive impairment.

RESULTS

Among 295 participants, 173 (58.6) were in 30-59 years; 154 (52.2%) were female; and 59 (20.0%) were exposed to indoor air pollution. Prevalence of cognitive impairment in the general population was 11.9% (95% confidence interval [CI]: 8.7-16.1). Prevalence of cognitive impairment among those who were exposed to indoor air pollution was 27.1% (95% CI: 17.4-39.6). Individuals exposed to indoor air pollution (aPR = 2.18, P = 0.003) were found to have two times more chance of having cognitive impairment.

CONCLUSION

About one-fourth of the participants were exposed to indoor air pollution, out of which more than one-fourth was found to have cognitive impairment which is twice that of the general population. Hence, prevention of exposure to indoor air pollution needs to be done through increased availability to cleaner fuels for household usage.

Prevalence and risk factors associated with latent tuberculosis infection among household contacts of smear positive pulmonary tuberculosis patients in South India

OBJECTIVE

We aimed to determine the prevalence and find the risk factors associated with latent tuberculosis infection (LTBI) among the household contacts (HHC) of pulmonary TB patients.

METHODS

This cohort study was conducted from 2014 to 2019. Pretested standardised questionnaires and tools were used for data collection. The prevalence of LTBI among HHCs of TB patients was summarised as proportion with 95% confidence interval (CI). Mixed-effects generalised linear modelling function (meglm) in STATA with family Poisson and log link was performed to find the factors associated with LTBI.

RESULTS

In total, 1523 HHC of pulmonary TB patients were included in the study. Almost all HHC shared their residence with the index case (IC) for more than a year; 25% shared the same bed with the IC. The prevalence of LTBI among the HHC of TB patients was 52.6% (95% CI: 50.1-55.1%). In an adjusted model, we found that among HHC belonging to the age group of 19-64 years (aIRR = 1.2; 95% CI: 1.1-1.3; p-value: 0.02), to the age group >65 years (aIRR = 1.4, 95% CI: 1.1-1.9, p-value: 0.02) and sharing the same bed with the IC (aIRR = 1.2, 95% CI: 1.1-1.3, p value: 0.04) were independent determinants of LTBI among the HHC.

CONCLUSION

One in two household contacts of TB patients have latent tuberculosis infection. This underscores the need of targeted contact screening strategies, effective contact tracing and testing using standardised methods in high TB burden settings.

Patient and provider's perspective on barriers and facilitators for medication adherence among adult patients with cardiovascular diseases and diabetes mellitus in India: a qualitative evidence synthesis

OBJECTIVE

To explore the various stakeholders' perspectives on barriers and facilitators for medication adherence among patients with cardiovascular diseases (CVDs) and diabetes mellitus (DM)in India.

DESIGN

Systematic review of qualitative studies.

DATA SOURCES

A comprehensive systematic search was conducted in Medline, Cochrane Library, Science Direct and Google Scholar from January 2010 to July 2020. We included all qualitative peer-reviewed studies, reporting barriers and facilitators of medication adherence, from India, for our current review.

DATA EXTRACTION AND SYNTHESIS

Data extraction was performed by two independent authors who also assessed the quality of included studies using the Critical Appraisal Skills Programme criteria. This qualitative evidence synthesis adhered to the enhancing transparency in reporting the synthesis of qualitative research checklist RESULTS: In total, 18 studies were included. Major barriers reported were lack of understanding about the disease, complications related to non-adherence, followed by forgetfulness, lack of family support and risk communication. Health system-related barriers such as accessibility, affordability and acceptability were also reported by majority of the studies. Creation of peer support groups, digital reminder systems, integration of native Indian systems of India, physiotherapy and geriatric clinics at the primary healthcare level and innovations in patient care were suggested to counter these barriers in medication adherence.

CONCLUSION

Such patient-specific targeted interventions need to be developed to achieve better control among patients with CVD and DM.PROSPERO registration numberCRD42020199529.

Impact and cost effectiveness of pneumococcal conjugate vaccine in India

BACKGROUND

World Health Organization has recommended the introduction of pneumococcal conjugate vaccine (PCV) in the childhood immunisation programme of all the countries in the world. In lieu of its introduction in India, there is a need to generate evidence on cost-effectiveness of this vaccine. The current study looks into the impact and cost-effectiveness of PCV vaccine in India.

METHODS

We evaluated the cost effectiveness of implementation of PCV 13 vaccination program at national level by comparing with no vaccination program for a period of 10 birth cohorts from 2018 to 2027. UNIVAC, a deterministic static cohort model is developed by giving the conservative estimates of vaccine program related to mortality, disease event rates, vaccine efficacy and coverage projections, system and health care costs for the first five years of life. Cost effectiveness is reported as Incremental Cost Effectiveness Ratio (ICER). Further scenario and sensitivity analysis were done. Probability of PCV intervention to be cost effective at a willingness to pay (WTP) threshold equal to per capita gross domestic product (GDP) is calculated using the government perspective.

RESULTS

We found that the introduction of PCV vaccination program can cost an additional $467 (INR 31,666) for averting per DALY which is less than one time GDP per capita of India. Even with the most unfavourable scenario for PCV vaccine, cost per DALY averted is found to be $2323 (INR 1,57,520) which is still a cost effective intervention in India. Probabilistic sensitivity analysis found the ICER for PCV to be $649 (INR 44,008) with 95% CI: $374-$1161.

CONCLUSION

This study shows that the PCV program is a highly cost effective intervention and justifies the introduction of PCV into routine immunisation schedule in some of the states and recommends introducing it throughout the country to reduce morbidity and mortality among the under-five children.

Association between indoor air pollution and cognitive function among nationally representative sample of middle-aged and older adults in India-A multilevel modelling approach

We have used a nationally representative sample of middle-aged and older adults in India to study the association between indoor air pollution and cognitive function. Longitudinal aging study in India (LASI) Wave-I data was utilized for this study. A two-level mixed-effects linear regression model was used to study the association between indoor air pollution and cognitive function and interpreted as adjusted beta coefficient (ꞵ) with 95% confidence interval (CI). In total, 56,179 participants aged ≥45 years were included in the analysis. The proportion of participants living in households with indoor air pollution were 30.6% (95%CI: 30.0%-31.3%). After adjusting for all the potential confounders (age, gender, education, region, religion, separate kitchen, socioeconomic status, marital status, residence, smoking, alcohol consumption, body mass index, self-rated health, and sleep problems), participants living in households with indoor air pollution had significant decline in the cognitive function when compared to those living in households without indoor air pollution (ꞵ = -0.57; 95%CI: -0.69 to -0.45). Since the LASI survey is being conducted as a biennial panel survey, assessing the impact of indoor air pollution on cognitive decline using the follow-up data can provide further insights into the pathogenesis of condition.

Prevalence and determinants of breast and cervical cancer screening among women aged between 30 and 49 years in India: Secondary data analysis of National Family Health Survey - 4

BACKGROUND

">Breast and cervical cancers are the two leading causes of cancer-related morbidity and mortality in India. Early diagnosis of these cancers through screening offers the best chance to achieve successful treatment outcomes. Hence, the current study was done to determine the prevalence and predictors of breast and cervical cancer screening among women aged 30-49 years in India.

METHODS

We have analyzed the most recent National Family Health Survey-4 data (NFHS-4) gathered from Demographic Health Survey program. Stratification and clustering in the sample design were accounted using svyset command. Adjusted prevalence ratio (aPR) with 95% confidence interval (CI) was reported.

RESULTS

In total, 336,777 women aged 30-49 years were included. Proportion of women aged 30-49 years with history of breast cancer examination in their lifetime was 12.9% (95% CI: 12.6-13.2%), while it was 29.8% (95% CI: 29.3-30.3%) for cervical cancer. It was found that women aged 45-49 years (aPR=1.09), married (aPR=2.18), higher educational level (aPR=1.28), richest quantile (aPR=1.96), no history of pill use (aPR=1.24), obese (aPR=1.06), and healthy dietary habits (aPR=1.47) were more likely to be screened for breast cancer. Predictors for cervical cancer screening were higher age group (aPR=1.06), married (aPR=2.94), secondary educational level (aPR=1.05), richest quantile (aPR=2.24), nonpill user (aPR=1.24), nontobacco user (aPR=1.07), and lower parity (aPR=1.09).

CONCLUSION

A total of 1 out of 10 women in reproductive age group were screened for breast cancer while less than one in three for cervical cancer. Hence, it is important to spread awareness and increase access to screening services to achieve early diagnosis and better treatment outcomes.

Construct Validation and Reliability Assessment of Tamil Version of Epworth Sleepiness Scale to Evaluate Daytime Sleepiness among Adolescents in Rural Puducherry, South India

BACKGROUND

Epworth sleepiness scale (ESS) has been used widely in the assessment of daytime sleepiness for research and clinical purposes. Hence, this study was done to translate the ESS in Tamil and to assess the construct validity and reliability of the Tamil version among adolescents in rural Puducherry, South India.

MATERIALS AND METHODS

Translation of the ESS by native language experts and pilot tested with subsample of adolescents. Final Tamil version was administered among 789 Tamil-speaking adolescents in the selected villages of rural Puducherry (union territory in South India). Construct validity was assessed by exploratory factor analysis through principal component method. Confirmatory factor analysis was done to obtain the goodness-of-fit. Reliability of questionnaire was assessed through Cronbach's alpha coefficient.

RESULTS

Two factor structures were obtained with Eigenvalues of 3.49 and 1.09, respectively. Both factors accounted for about 57.4% of the variance. Two-factor model assessed by confirmatory factor method found Chi-square value of 215.57 (P < 0.001). Goodness-of-fit revealed acceptable comparative fit indices (0.91). The reliability coefficient (Cronbach's alpha) for complete ESS was 0.81. Factor-based analysis showed that the Cronbach's reliability coefficient was 0.83 and 0.75 for the first and second factor, respectively.

CONCLUSION

Our study concludes that the ESS questionnaire is internally valid and consistent with good reliability coefficient for application in Tamil-speaking rural adolescents. However, further research can be done to content validate the questionnaire with standard diagnostic tool.

Fat taxation in India: A critical appraisal of need, public health impact, and challenges in nationwide implementation

National Nutritional Monitoring Bureau survey (2017) has found that more than half of the adults in India were overweight and obese. To halt this rising epidemic, development of various policy measures has been suggested in National action plan for prevention and control of noncommunicable diseases. One such measure is the introduction of fat tax which is a surcharge or tax placed on food and beverages containing high amounts of fat. Government of India has made various direct budgetary initiatives for boosting the sectors related to the production of items rich in fat, sugars and salt without realizing the potential public health consequences. Hence, increasing the taxes for unhealthy junk foods should encourage the people to take healthier food options which in turn lead to positive impact on health. However, fat taxationfaced several challenges during implementation in countries like Denmark, Hungary, France and United States. Major challenges were the taxation debate, setting tax limit and encroaching into the autonomy rights of people. Evidences have shown that taxation alone cannot bring down the burden of non-communicable diseases but should be combined with measures like subsidies and access to healthy food items, public health education campaigns and programmes.

Prevalence of hypertension among professional drivers: Evidence from 2000 to 2017-A systematic review and meta-analysis

BACKGROUND

Hypertension is one of the leading causes of premature deaths worldwide. Drivers have an additional risk of hypertension when compared to the general population because of the nature of their profession. Hence, the current review was done to estimate the global burden of hypertension among professional drivers.

METHODS

We conducted a systematic search for articles on the prevalence of hypertension among drivers published from 2000 to 2017 in Medline and Embase. Meta-analysis was performed using the random-effects model and pooled prevalence of hypertension was reported. Heterogeneity was assessed using the likelihood ratio (LR) test and publication bias was assessed using Egger's test.

RESULTS

In total, 26 studies with 15,702 drivers were included. The pooled prevalence of hypertension among the drivers worldwide was 34% (95% confidence interval [CI]: 27-40%). World Health Organization (WHO) region-wise estimates showed that prevalence was highest among the drivers in the Western Pacific region (56%) and lowest in the Eastern Mediterranean and African region (21%). Studies showed significant evidence of heterogeneity (χ2 = 1816.1,P < 0.001) but there was no significant publication bias (P = 0.967).

CONCLUSION

More than one-third of drivers have hypertension globally which is in excess of the general population. Hence, more focus needs to be given for allocating resources and developing workplace interventions for prevention and control of hypertension.

Equity in coverage of maternal and newborn care in India: evidence from a nationally representative survey

Despite efforts taken by the Government of India, mothers and newborns are excluded from the maternal and child health services, especially those in poorer and weaker sections of the society. Hence, we have utilized the most recent National Family Health Survey (NFHS-4) data to assess the socio-economic inequities in antenatal care (ANC), intranatal care and postnatal care (PNC) coverage for mothers and newborns in India. We have analysed the NFHS-4 data gathered from the Demographic Health Survey programme. Stratification and clustering in the sample design were accounted for using 'svyset' command. Point estimates were reported as proportions with 95% confidence interval. The concentration curve and index were used to represent the socio-economic inequities. Theil index was computed to report inequities across geographical regions and place of residence. In total, 190 797 women who had at least one live birth in the preceding 5 years were included. About 52.1% of women had at least four ANC visits and 81.4% had institutional delivery. About 25.2% and 27.1% of the newborn received PNC within 24 and 48 h of delivery. The proportion of women who received PNC within 24 and 48 h after the delivery was 63.4% and 65.2%, respectively. Maximum inequity was observed for ANC (concentration index-0.195) followed by receipt of PNC by mothers within 24 and 48 h (concentration index-0.106 and 0.103). Women from the rural areas had a disproportionately high proportion of home deliveries (Theil index-3813.6). The findings from this study inform the policymakers and planners about the socio-economic inequity existing across various maternal and child health indicators. This will help them in making informed decisions and strengthen the maternal and child health programme in our country.

Impact of tobacco industry pricing and marketing strategy on brand choice, loyalty and cessation in global south countries: a systematic review

OBJECTIVES

We undertook this review to assess the impact of pricing strategies on brand choice, loyalty and quitting behaviour in Global South countries.

METHODS

We systematically retrieved articles from Medline, CENTRAL, ScienceDirect, Google Scholar from inception up to January 2020. Studies which reported tobacco industry's pricing strategies were eligible. We summarized the data as themes and codes using the principles of inductive qualitative thematic analysis within structured rational constructivist framework.

RESULTS

In total, 13 studies met inclusion criteria were included. Major strategies adopted by tobacco industries to tackle the pricing and taxation changes were increased tax absorption, differential taxation based on price, cigarette length/size which ensures modest increase in the net price of cigarettes. This in turn influences the tobacco users in terms of brand loyalty and switching as they prefer to stay with factory-made cigarettes or shift to a cheaper alternative or illegal product rather than decreasing/quitting tobacco use.

CONCLUSIONS

Absorption of excise tax and differential taxation are the common pricing strategies adopted by tobacco industries in Global South. These strategies together with external determinants impact the price-related tobacco control interventions.

Association between behavioural risk factors and metabolic syndrome among adult population in India: A systematic review and meta-analysis of observational studies

AIMS

The impact of behavioural risk factors on the metabolic syndrome has not been well understood by the researchers. This information is important to the policymakers for developing effective strategies and implement relevant policies or programs. Hence, we undertook this meta-analysis to estimate the effect of behavioural risk factors on the burden of metabolic syndrome.

DATA SYNTHESIS

We conducted a search in the databases, such as PubMed Central, EMBASE, MEDLINE, and Cochrane library, and search engines, such as ScienceDirect and Google Scholar, from inception until March 2021. We used the Newcastle-Ottawa Scale (NOS) to assess the quality of published studies. We carried out a meta-analysis with random-effects model and reported pooled odds ratio (OR) with 95% confidence interval (CI). In total, we analysed 30 studies with 41,090 participants. The majority of the studies had good to satisfactory quality as per NOS. Physical activity had a statistically significant association with the prevalence of metabolic syndrome (pooled OR = 1.57; 95%CI: 1.28 to 1.93, I2 = 91%). However, smoking (pooled OR = 0.96; 95%CI: 0.75 to 1.23, I2 = 90.5%) and alcohol (pooled OR = 1.00; 95%CI: 0.75 to 1.33, I2 = 90.8%) did not reveal a statistically significant association with the burden of metabolic syndrome.

CONCLUSION

Physical inactivity was found to be a significant risk factor for metabolic syndrome. Given the evidence, it is important that the clinicians and policymakers are alike to recommend regular physical activity among the patients and general population.

Impact of antenatal care visits on childhood immunization: a propensity score-matched analysis using nationally representative survey

BACKGROUND

Evidence has suggested a relationship between antenatal care (ANC) visits and childhood immunization coverage. However, evaluating its impact using observational data suffers from the problem of selection bias. Hence, we adopted propensity score-matched (PSM) analysis for studying the impact of ANC visits on childhood immunization.

METHODS

Data regarding ANC visits and childhood immunization were collected from a nationally representative survey, National Family Health Survey-4 (NFHS-4). We performed PSM analysis with logit model using the psmatch2 command package in STATA to find the average treatment effect on the population (ATE), treated (ATT), and untreated (ATU).

RESULTS

In total, 5,430 participants were included in the analysis. Radius matching with caliper width of 0.01 was used to match the groups. The ATT values in the intervention and control groups were 0.71 and 0.47, respectively, indicating that the immunization coverage was increased by 24% because of ANC visits. The ATU values in the intervention and control groups were 0.40 and 0.65, respectively. This indicates that for the women who did not make the ANC visits, the chance of getting their children immunized would have increased by 25% if they had made four or more visits. The final ATE estimate was 0.25 among the study participants. Quality of matching was good with no significant difference in characteristics between the two groups.

CONCLUSION

Findings from our study imply that policymakers in India should focus on further improving the ANC coverage as it has a significant impact on improving childhood immunization coverage.

Spatial Pattern and Determinants of Tobacco Use Among Females in India: Evidence From a Nationally Representative Survey

INTRODUCTION

Tobacco use has been steadily increasing among the females in developing countries. It has led to rise in tobacco-related morbidity and mortality among females. Knowing the geographic distribution of the habit is essential to identify high-priority areas and direct the healthcare intervention. Hence, this study was done to assess the spatial patterns and determinants of tobacco consumption among females in India.

AIMS AND METHODS

Univariate and bivariate Moran's I statistic and local indicators for spatial association maps were generated to determine the spatial clustering of tobacco consumption (smoked and smokeless form). Ordinary least-square regression, spatial-lag and spatial-error models were performed to assess the determinants. Poverty (belonging to poorest and poorer quintile of wealth index), illiteracy (no formal education), marital status, ST population, tobacco use by family members, and alcohol use were the explanatory variables.

RESULTS

Univariate Moran's I was .691 suggesting positive spatial autocorrelation. High-prevalence clustering (hotspots) was maximum in the central, eastern, and northeastern states such as Chhattisgarh, Madhya Pradesh, Odisha, Bihar, Manipur, Tripura, Meghalaya, Mizoram, and Assam. This pattern was similar for both smokeless and smoked form. Results of spatial-lag and spatial-error model suggested that alcohol use, scheduled tribes, illiteracy, poverty, marital status, and tobacco use by family members were significant determinants of female tobacco consumption. The coefficient of spatial association was maximum for alcohol use (β = .20, p < .001) followed by widowed/separated/divorced (β = .12, p < .001).

CONCLUSIONS

Tobacco consumption among females in India is spatially clustered. Multisectoral coordination and targeted interventions are required in the geographical hotspots of tobacco consumption.

IMPLICATIONS

This is the first study to explore the geospatial pattern of tobacco consumption among females in India. We found that the pattern of tobacco use among females is spatially clustered in India. Clustering was predominantly found in central, eastern, and northeastern regions of the country. Tribal population in these areas and complementarities between alcohol and tobacco use contributed significantly to the high-prevalence clustering. These findings will be helpful for policymakers and planners to devise specific intervention package targeting the high-risk regions.

Prevalence of hypertension and determinants of treatment-seeking behaviour among adolescents and young adults in India: an analysis of NFHS-4

BACKGROUND

Previous evidences have reported that almost three-fourth of young hypertensives are not seeking care for their condition leading to severe complications. This study was conducted to assess the determinants of treatment-seeking behaviour among the young hypertensives in India.

METHODS

The National Family Health Survey-4 data were analysed. Sampling weights and clustering was accounted using svyset command. Screening, awareness, prevalence and control status were reported with 95% confidence interval (CI). Poisson regression was done to identify the determinants of treatment-seeking behaviour.

RESULTS

In total, 13.8% of younger adults had hypertension, 51.1% were aware of their status and 19.5% sought treatment. Participants in 15-19 years (adjusted Prevalence Ratio (aPR) = 0.70) and 20-29 years (aPR = 0.63), male gender (aPR = 0.84), Muslim religion (aPR = 1.14), urban region (aPR = 0.87), secondary (aPR = 0.88) and higher education (aPR = 0.86), residing in Northern (aPR = 0.79), Central (aPR = 0.76), Southern region (aPR = 0.65), preferring home treatment, medical shop or any other care (aPR = 0.63) were significant determinants of treatment-seeking behaviour.

CONCLUSION

More than 1 in 10 younger adults in India have hypertension and only half of them were aware of their status and one-fifth sought treatment. Adolescents, males, Hindus, urban population, higher education and residing in Northern, Central and Southern region had poor treatment-seeking behaviour.

Spatial pattern and determinants of HIV infection among adults aged 15 to 54 years in India - Evidence from National Family Health Survey-4 (2015-16)

OBJECTIVE

To assess the spatial pattern and determinants of HIV infection in India.

METHODS

We conducted a secondary data analysis using the National Family Health Survey-4 data obtained from the Demographic Health Survey programme. We accounted for clustering and stratification in the sampling design using the svyset command. Spatial analysis was performed by generating the Moran's I statistic and local indicators for spatial association (LISA) maps. Logistic regression was performed to identify the determinants of HIV infection.

RESULTS

230 213 individuals were included. Prevalence of HIV infection in India was 0.24% (95% CI: 0.21%-0.28%). Being separated/widowed/divorced (aOR = 2.58, 95% CI: 1.22-5.40), living in an urban area (aOR = 2.46, 95% CI: 1.79-3.37), being resident in the North-Eastern (aOR = 4.25, 95% CI: 2.60-6.93), Southern (aOR = 3.13, 95% CI: 1.99-4.91) or Western region (aOR = 2.17, 95% CI: 1.08-4.33), having a history of multiple sexual partners (aOR = 1.99, 95% CI:1.42-2.79), a suspected STI (aOR = 2.32, 95% CI: 1.38-3.90) or self-reported TB (aOR = 7.80, 95% CI: 2.52-24.05) were significantly in association with HIV infection. Moran's I was 0.377, suggesting positive spatial autocorrelation. The LISA cluster map indicated 60 hotspot districts in India, mostly in southern states such as Karnataka, Andhra Pradesh and Telangana followed by north-eastern states such as Nagaland, Manipur, Mizoram, Tripura and Assam.

CONCLUSION

HIV infection among adults aged 15-54 years in India is spatially clustered with the majority occurring in southern and north-eastern states. Hence, region- or district-specific strategies with focused interventions should be adopted.

Prevalence and Determinants of Physical Violence and Its Impact on Birth Outcomes During Pregnancy in India: Evidence From a Nationally Representative Survey

Physical violence during pregnancy can have negative impact on health status of mother and fetus. Hence, the current study was done to determine the prevalence and determinants of physical violence and its impact on birth outcomes during pregnancy in India. We have analyzed the most recent National Family Health Survey 4 data (NFHS-4) gathered from Demographic Health Survey (DHS) program. Stratification (urban/rural) and clustering (villages/census enumeration blocks [CEBs]) in the sample design was accounted using svyset command. In total, 62,165 ever pregnant women aged 15 to 49 years were included. Prevalence of physical violence during pregnancy in India was 3.3%. Husband/partner (2.7%) was the person most commonly responsible. Women who were widowed/separated/divorced (aPR = 1.88), belonging to the poorest quantile (aPR = 2.32), women who were employed (aPR = 1.42), women in the Southern states (aPR = 3.24), and women whose husband/partner has lesser educational qualification (adjusted prevalence ratio [aPR] = 2.02) had significantly higher prevalence of physical violence during pregnancy (p < .001). Women who faced physical violence had significantly higher proportion of miscarriage (4.3%), abortion (3.3%), and stillbirth (1.1%) when compared with women who did not face any violence (4.1% had miscarriage, 1.8% had abortion, and 0.5% had stillbirth; p < .001). These findings show the importance of providing general supportive measures and strengthen the existing punitive legislations to prevent the violence during pregnancy.

Assessment of Quality of Life Based on Psychological, Somatovegetative, and Urogenital Health Problems among Postmenopausal Women in Urban Puducherry, South India: A Cross-Sectional Observational Study

BACKGROUND

An average Indian woman spends almost one-third of her lifespan in the postmenopausal phase enduring the consequences of hormonal decline. This can have a significant impact on quality of life (QOL). Hence, this study was conducted to assess the QOL and health problems among postmenopausal women in urban Puducherry, South India.

METHODS

A cross-sectional study was carried out among postmenopausal women attending urban primary health center between April and May 2017. Information about social, economic, and demographic characteristics was collected using a semi-structured questionnaire, and menopause rating scale was used to assess the QOL.

RESULTS

Among 204 participants, 55.4% belonged to elderly age group (≥60 years); 61.3% did not have any formal education; 55.9% of the participants were unemployed; 68.7% were widowed, separated, or divorced; 89.7% belonged to Hindu religion; and 42.2% belonged to lower socioeconomic class. Majority (78%) suffered from psychological problems followed by somatovegetative (62%) and urogenital problems (33%). The prevalence of poor QOL was 37.2% (95% confidence interval: 30.8%-44.0%). Participants belonging to Hindu religion (annual percentage rate [aPR]-4.14), in nuclear family (aPR-2.31), and with chronic comorbidity (aPR-5.52) and alcohol/tobacco users (aPR-6.03) had significantly higher risk of poor QOL.

CONCLUSION

The current study found that more than one-third of the postmenopausal women in urban Puducherry have poor QOL with majority suffering from psychological problems. Hence, more focus needs to be given to this target population to achieve physical, social, and mental well-being among females.

Economic evaluation and budget impact analysis of dengue vaccination following pre-vaccination serological screening in India

OBJECTIVES

To evaluate the budget impact and cost-effectiveness of dengue vaccination following pre-vaccination serological screening in India.

METHODS

We used a static cohort model (combination of decision tree and Markov model) to compare dengue disease and cost burden with and without dengue vaccination program with serological screening for a hypothetical cohort of 10-year-old adolescents. Budget impact was expressed in terms of total budget required for implementation of vaccination programme. Program impact was expressed in terms of disability-adjusted life-years (DALYs) averted. Cost effectiveness was expressed as costs per DALY averted. All costs are expressed in 2018 US dollars. Sensitivity analysis was performed for ICERs in different vaccination scenarios.

RESULTS

The total budget for implementation of dengue vaccination programme is approximately around US$ 530 million (INR 3620 crores). Our model results suggest dengue vaccination result in a net gain of almost 86,000 DALYS. We found the Dengue vaccine to be a cost-effective intervention with an ICER of $3364 (INR 2,30,098) which is less than three-times GDP per capita of India ($6047; INR 413,601). One-way sensitivity analysis shows that the ICER is most affected by the overall incidence of dengue infections followed by vaccine price. Probabilistic sensitivity analysis shows that ICER for dengue vaccination varied from $1182 (INR 80,837) to $6367 (INR 435,439).

CONCLUSION

Our study shows that dengue vaccine with pre-vaccination serological screening programme is a cost-effective intervention with the conservative estimates.
