Undernourished Household Contacts Are at Increased Risk of Tuberculosis (TB) Disease, but not TB Infection- a Multicenter Prospective Cohort Analysis.

Undernutrition is the leading risk factor for tuberculosis (TB) globally and in India. This multicenter prospective cohort analysis from India suggests that undernutrition is associated with increased risk of TB disease but not TB infection among household contacts of persons with TB.

Factors associated with unfavourable treatment outcomes among persons with Pulmonary Tuberculosis: a multicentric prospective cohort study from India.

In this prospective cohort of 2,006 individuals with non-MDR tuberculosis in India, 18% had unfavorable treatment outcomes (4.7% treatment failure, 2.5% recurrent infection, 4.1% death, 6.8% loss to follow-up) over a median 12-month follow-up period. Age, male sex, low education, nutritional status, and alcohol use were predictors of unfavorable outcomes.

Impact of Undernutrition on Tuberculosis Treatment Outcomes in India: A Multicenter, Prospective, Cohort Analysis.

BACKGROUND: Undernutrition is the leading risk factor for tuberculosis (TB) globally. Its impact on treatment outcomes is poorly defined. METHODS: We conducted a prospective cohort analysis of adults with drug-sensitive pulmonary TB at 5 sites from 2015-2019. Using multivariable Poisson regression, we assessed associations between unfavorable outcomes and nutritional status based on body mass index (BMI) nutritional status at treatment initiation, BMI prior to TB disease, stunting, and stagnant or declining BMI after 2 months of TB treatment. Unfavorable outcome was defined as a composite of treatment failure, death, or relapse within 6 months of treatment completion. RESULTS: Severe undernutrition (BMI <16 kg/m2) at treatment initiation and severe undernutrition before the onset of TB disease were both associated with unfavorable outcomes (adjusted incidence rate ratio [aIRR], 2.05; 95% confidence interval [CI], 1.42-2.91 and aIRR, 2.20; 95% CI, 1.16-3.94, respectively). Additionally, lack of BMI increase after treatment initiation was associated with increased unfavorable outcomes (aIRR, 1.81; 95% CI, 1.27-2.61). Severe stunting (height-for-age z score <-3) was associated with unfavorable outcomes (aIRR, 1.52; 95% CI, 1.00-2.24). Severe undernutrition at treatment initiation and lack of BMI increase during treatment were associated with a 4- and 5-fold higher rate of death, respectively. CONCLUSIONS: Premorbid undernutrition, undernutrition at treatment initiation, lack of BMI increase after intensive therapy, and severe stunting are associated with unfavorable TB treatment outcomes. These data highlight the need to address this widely prevalent TB comorbidity. Nutritional assessment should be integrated into standard TB care.

Effect of treatment adherence on the association between sex and unfavourable treatment outcomes among tuberculosis patients in Puducherry, India: a mediation analysis.

BACKGROUND: A better understanding of the complex interplay between risk factors of tuberculosis (TB) is essential. This study was part of the Regional Prospective Observational Research for Tuberculosis (RePORT) India consortium and includes newly diagnosed TB patients in Puducherry between 2014 and 2018. We employed mediation analysis to identify the effect of treatment adherence on association between sex and unfavourable TB treatment outcomes. METHODS: Required demographic and treatment-related variables were extracted from the RePORT India consortium database and causal mediation analysis using parametric regression models was done. RESULTS: Of the 712 TB patients, ~87 (12.2%) had unfavourable TB treatment outcomes. Total effect of male sex was significantly associated with the unfavourable TB treatment outcomes [adjusted odds ratio (aOR) = 2.48; 95% confidence interval (CI): 1.11-5.55]. However, the overall association between male sex and TB treatment outcomes was dominated by the indirect pathway, as the direct pathway does not show significant association (aOR = 1.67; 95% CI: 0.75-3.75), while the indirect pathway shows significantly higher odds of TB treatment outcomes (aOR = 1.48; 95% CI:1.27-1.73), indicating complete mediation by the treatment adherence. CONCLUSIONS: The study has shown a complete mediation of sexes through TB treatment adherence for unfavourable treatment outcomes. Developing of treatment strategies require better understanding between the biological and social factors related to TB.

Predictors of weight loss during the intensive phase of tuberculosis treatment in patients with drug-susceptible pulmonary tuberculosis in South India.

BACKGROUND: Tuberculosis (TB) is well-known for causing wasting. Patients on treatment gain weight and weight loss is associated with unfavorable treatment outcomes. There is limited description of weight loss and its predictors during intensive treatment phase. The objective of this study was to assess the predictors of weight loss during intensive phase and to see if there is any association exists with sputum conversion at the end of intensive phase of treatment. METHODS: Data collected as a part of the prospective TB cohort (Regional Prospective Observational Research for TB India Phase 1) conducted in Pondicherry, Cuddalore and Viluppuram districts of Tamil Nadu were used for this study. Sputum smear and body weight comparison were made in the baseline and at the end of second month of treatment. RESULTS: In all, 726 participants had weight measurements at the two time points and 18.7% had weight loss; mean weight lost being 2.3 kg (SD 3.05). Mean weight loss was more among males (2.4 kg, SD 3.2), diabetics (2.8 kg, SD 3.9) and alcoholics (2.1 kg, SD 2.4). Alcohol consumption was the only predictor of weight loss after adjusting for age, diabetes, marital status and BMI (aRR 1.52, P 0.02). Weight loss was not associated with sputum conversion at the end of second month. CONCLUSIONS: Alcohol use emerged as the major predictor for weight loss during intensive phase.

Development of prognostic scoring system for predicting 1-year mortality among pulmonary tuberculosis patients in South India.

BACKGROUND: Development of a prediction model using baseline characteristics of tuberculosis (TB) patients at the time of diagnosis will aid us in early identification of the high-risk groups and devise pertinent strategies accordingly. Hence, we did this study to develop a prognostic-scoring model for predicting the death among newly diagnosed drug sensitive pulmonary TB patients in South India. METHODS: We undertook a longitudinal analysis of cohort data under the Regional Prospective Observational Research for Tuberculosis India consortium. Multivariable cox regression using the stepwise backward elimination procedure was used to select variables for the model building and the nomogram-scoring system was developed with the final selected model. RESULTS: In total, 54 (4.6%) out of the 1181 patients had died during the 1-year follow-up period. The TB mortality rate was 0.20 per 1000 person-days. Eight variables (age, gender, functional limitation, anemia, leukopenia, thrombocytopenia, diabetes, neutrophil-lymphocyte ratio) were selected and a nomogram was built using these variables. The discriminatory power was 0.81 (95% confidence interval: 0.75-0.86) and this model was well-calibrated. Decision curve analysis showed that the model is beneficial at a threshold probability ~15-65%. CONCLUSIONS: This scoring system could help the clinicians and policy makers to devise targeted interventions and in turn reduce the TB mortality in India.

Outcome of emergency obstetric cases in relation to the referral pattern at a tertiary hospital in Puducherry: A cross-sectional descriptive study.

Background: Referral is a crucial aspect of emergency obstetric care in India. Adequate and timely referrals help to improve the quality of health-care services and maternal and child well-being. Objectives: Studies are needed to assess the outcome of obstetric mothers' emergency admissions in relation to referral patterns. Materials and Methods: A hospital-based cross-sectional descriptive study was done among obstetric patients admitted to a tertiary care hospital's emergency department (emergency medical service [EMS]). A retrospective cohort was analyzed. The data were entered in Epicollect5 and imported to STATA software version 16 for analysis. Results: A total of 685 mothers admitted to EMS were selected for the study, with a mean (standard deviation) age of 26.5 years (4.2). Among the study participants, 181 (26.4%) were referred from other institutions, 382 (55.8%) were nonreferral who received antenatal checkups in the tertiary hospital, and 122 (17.8%) were self-referral who had not received any antenatal checkup in the tertiary hospital. The adverse fetal outcome was 1.88 (1.21-2.95) times higher in the referred mothers compared to the self-referral. Conclusion: We observed that a higher percentage of referrals were from the primary health centers. This kind of direct referral to tertiary care hospitals can be avoided by availing the emergency obstetric services at secondary hospitals to prevent adverse fetal outcomes and unnecessary referrals to the tertiary hospital.

Impact of COVID-19 Pandemic on Tuberculosis Care and Treatment in Puducherry - A Mixed Method Study.

BACKGROUND: The shift of focus toward pandemic control had an impact on public health issues that need to be addressed. As the impact may vary in the different areas based on COVID-19 cases and strictness of measures to control the disease, studying the local situation and related factors is essential to strengthening the TB program. OBJECTIVES: The objective is to compare the TB care before and during the COVID-19 pandemic and to explore the challenges faced by stakeholders during the pandemic. MATERIALS AND METHODS: A mixed method study was conducted in Puducherry with a quantitative phase involving data extraction from the National TB Elimination Programme (NTEP), followed by in-depth interviews to explore the challenges faced by stakeholders. RESULTS: In 2020, there were 67% and 23% reductions in number of presumptive TB case and notified TB cases, respectively, while the decline was lesser in the year 2021 (reduction of 59% and 13%, respectively). The main challenges faced in providing and accessing TB care were social stigma, lockdown restrictions, fear of getting COVID-19, redeployment of staff to COVID-19-related activities and increased COVID-19 workload. CONCLUSIONS: There is a need to strengthen active case finding for the missed TB cases through the mobile vans equipped with diagnostics, combined testing for COVID-19 and TB, greater inclusion of private sector and dispensaries as well as community awareness for stigma prevention.

Mapping of Palliative Care Services and Challenges in Implementation of National Program for Palliative Care in Puducherry.

Objectives: The purpose of this study was to map ongoing palliative care services and describe the characteristics of providers, recipients, level of care, and approach. Second, it seeks to investigate the difficulties encountered in implementing NPPC in the Puducherry district of UT Puducherry. This study aims to review the challenges in its implementation. Material and Methods: The study using both quantitative and qualitative design, including geospatial mapping of organisations, describing service delivery characteristics and exploring challenges faced in implementing NPPC, was conducted from July 2021 to January 2022. In-depth interviews were conducted with seven healthcare providers, four patients and three caregivers, as well as key informant interviews with six doctors in administration. Results: Thirteen organisations providing palliative care to population of Puducherry district of union territory Puducherry and neighbouring districts of Tamil Nadu were identified. Mapped organisations were primarily concentrated in urban areas. Morphine was available only at three medical colleges, providing outpatient palliative care services. Non-governmental organisations provided only home-based palliative care services and the hospices provided both in-patient and home-based services. Key barriers perceived by the health system were difficulty in procuring morphine, inadequate personnel and inadequate funding. Few barriers perceived by patients/family were stigma faced in community, psychological challenges and poor quality of care. Conclusions: Palliative care services are mainly available in urban areas and through private hospices. There is a need to implement palliative care program through the public health system to improve the accessibility in the rural areas.

Development and Validation of a Parsimonious Tuberculosis Gene Signature Using the digital NanoString nCounter Platform.

BACKGROUND: Blood-based biomarkers for diagnosing active tuberculosis (TB), monitoring treatment response, and predicting risk of progression to TB disease have been reported. However, validation of the biomarkers across multiple independent cohorts is scarce. A robust platform to validate TB biomarkers in different populations with clinical end points is essential to the development of a point-of-care clinical test. NanoString nCounter technology is an amplification-free digital detection platform that directly measures mRNA transcripts with high specificity. Here, we determined whether NanoString could serve as a platform for extensive validation of candidate TB biomarkers. METHODS: The NanoString platform was used for performance evaluation of existing TB gene signatures in a cohort in which signatures were previously evaluated on an RNA-seq dataset. A NanoString codeset that probes 107 genes comprising 12 TB signatures and 6 housekeeping genes (NS-TB107) was developed and applied to total RNA derived from whole blood samples of TB patients and individuals with latent TB infection (LTBI) from South India. The TBSignatureProfiler tool was used to score samples for each signature. An ensemble of machine learning algorithms was used to derive a parsimonious biomarker. RESULTS: Gene signatures present in NS-TB107 had statistically significant discriminative power for segregating TB from LTBI. Further analysis of the data yielded a NanoString 6-gene set (NANO6) that when tested on 10 published datasets was highly diagnostic for active TB. CONCLUSIONS: The NanoString nCounter system provides a robust platform for validating existing TB biomarkers and deriving a parsimonious gene signature with enhanced diagnostic performance.

Prevalence and Time Trend of SARS-CoV-2 Infection in Puducherry, India, August-October 2020.

We conducted 3 population-based cross-sectional surveys, at 1-month intervals, to estimate the prevalence and time-trend of severe acute respiratory syndrome coronavirus 2 infection in Puducherry, India. Seropositivity rate increased from 4.9% to 34.5% over 2 months and was 20-fold higher than the number of diagnosed cases of infection.

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.

Tuberculosis-Learning the Impact of Nutrition (TB LION): protocol for an interventional study to decrease TB risk in household contacts.

BACKGROUND: Comorbidities such as undernutrition and parasitic infections are widespread in India and other tuberculosis (TB)-endemic countries. This study examines how these conditions as well as food supplementation and parasite treatment might alter immune responses to Mycobacterium tuberculosis (Mtb) infection and risk of progression to TB disease. METHODS: This is a 5-year prospective clinical trial at Jawaharlal Institute of Post Graduate Medical Education and Research in Puducherry, Tamil Nadu, India. We aim to enroll 760 household contacts (HHC) of adults with active TB in order to identify 120 who are followed prospectively for 2 years: Thirty QuantiFERON-TB Gold Plus (QFT-Plus) positive HHCs ≥ 18 years of age in four proposed groups: (1) undernourished (body mass index [BMI] < 18.5 kg/m2); (2) participants with a BMI ≥ 18.5 kg/m2 who have a parasitic infection (3) undernourished participants with a parasitic infection and (4) controls-participants with BMI ≥ 18.5 kg/m2 and without parasitic infection. We assess immune response at baseline and after food supplementation (for participants with BMI < 18.5 kg/m2) and parasite treatment (for participants with parasites). Detailed nutritional assessments, anthropometry, and parasite testing through polymerase chain reaction (PCR) and microscopy are performed. In addition, at serial time points, these samples will be further analyzed using flow cytometry and whole blood transcriptomics to elucidate the immune mechanisms involved in disease progression. CONCLUSIONS: This study will help determine whether undernutrition and parasite infection are associated with gene signatures that predict risk of TB and whether providing nutritional supplementation and/or treating parasitic infections improves immune response towards this infection. This study transcends individual level care and presents the opportunity to benefit the population at large by analyzing factors that affect disease progression potentially reducing the overall burden of people who progress to TB disease. Trial registration ClinicalTrials.gov; NCT03598842; Registered on July 26, 2018; https://clinicaltrials.gov/ct2/show/NCT03598842.

Comparing tuberculosis gene signatures in malnourished individuals using the TBSignatureProfiler.

BACKGROUND: Gene expression signatures have been used as biomarkers of tuberculosis (TB) risk and outcomes. Platforms are needed to simplify access to these signatures and determine their validity in the setting of comorbidities. We developed a computational profiling platform of TB signature gene sets and characterized the diagnostic ability of existing signature gene sets to differentiate active TB from LTBI in the setting of malnutrition. METHODS: We curated 45 existing TB-related signature gene sets and developed our TBSignatureProfiler software toolkit that estimates gene set activity using multiple enrichment methods and allows visualization of single- and multi-pathway results. The TBSignatureProfiler software is available through Bioconductor and on GitHub. For evaluation in malnutrition, we used whole blood gene expression profiling from 23 severely malnourished Indian individuals with TB and 15 severely malnourished household contacts with latent TB infection (LTBI). Severe malnutrition was defined as body mass index (BMI) < 16 kg/m2 in adults and based on weight-for-height Z scores in children < 18 years. Gene expression was measured using RNA-sequencing. RESULTS: The comparison and visualization functions from the TBSignatureProfiler showed that TB gene sets performed well in malnourished individuals; 40 gene sets had statistically significant discriminative power for differentiating TB from LTBI, with area under the curve ranging from 0.662-0.989. Three gene sets were not significantly predictive. CONCLUSION: Our TBSignatureProfiler is a highly effective and user-friendly platform for applying and comparing published TB signature gene sets. Using this platform, we found that existing gene sets for TB function effectively in the setting of malnutrition, although differences in gene set applicability exist. RNA-sequencing gene sets should consider comorbidities and potential effects on diagnostic performance.

Extent of contraception methods practised by unmet need couples after counselling: a cross-sectional follow-up study in Puducherry, South India.

BACKGROUND: Information is paucity about the extent of contraception practise among the unmet need eligible couples after counselling. OBJECTIVE: To assess the prevalence and associated factors of unmet need for family planning (FP), the extent to which they practise desired contraception methods after baseline counselling and the reasons for not practicing it. METHODS: A community-based cross-sectional analytical study was conducted between 2016 and 2019 among 2228 currently married couples with periodic follow ups of unmet need group. Baseline data on unmet need were collected based on the National Family Health Survey questionnaire. Individual and couple counselling were performed through informing choice and the support for decision making was based on the unmet need reasons with follow-ups. The data were analysed using Stata software version 12.0 (StataCorp, College Station, TX). RESULTS: The total study population was 1924. The prevalence of unmet need for FP was 7.1% (137) with 2.9% (55) of unmet need for spacing and 4.3% (82) of limiting births. Age groups between 18 and 24 [adjusted odds ratio (AOR) = 4.463], 25-29 (AOR = 2.339), not having a child (AOR = 0.250), having one child (AOR = 2.369) and having lower socioeconomic status (AOR = 0.155) were significantly associated with unmet need. During the follow-ups, 37.2% (29/78) received who desired limiting births, while 43.6% (34/78) changed to spacing methods. In fact, the main reason for not adopting limiting births is the fear of post-operative surgery-related health problems. CONCLUSIONS: This study emphasizes the need for follow-up counselling for guiding contraceptive use and recorded that majority of the unmet need couples started practicing contraception methods during the follow-ups. Besides, change in desired contraception methods was observed.

Contraceptive knowledge, practice, and associated factors among currently married women of reproductive age group: A community-based study in Puducherry, India.

In the present cross-sectional study, the researchers aimed to assess the contraceptive knowledge, practice, and associated factors among 2228 women in Puducherry, India. National Family Health Survey questionnaire was adopted for data collection and about 1924 women participated. Current use of any contraceptive was 78.6% and female sterilization was 62%. The majority (99.8%) knew female sterilization, but below average for other contraceptive methods. About 10.4% were aware of more than three contraceptive methods. Age group, homemaker, with children or one son, aware of less than three methods, residing nearby to health facility were associated with the higher practice of contraceptive methods.

Preference on prenatal sex determination and its associated factors among currently married women of reproductive age group in Puducherry, India.

BACKGROUND: Sex determination refers to knowing the sex of foetus during prenatal period for non-medical reasons. Attitude of married women to sex determination is important to improve the sex ratio at birth. AIM AND OBJECTIVES: This study aimed to assess preference on sex determination and associated factors among currently married reproductive age group women. MATERIALS AND METHODS: This cross-sectional community-based study was done during 2016-2017 among 2228 currently married women of 18-49 years' age group in urban and rural Puducherry, India. Information on the demographic characteristics, level of awareness and preference for sex determination was obtained. Multiple logistic regression was used to identify factors influencing preference for sex determination. Unadjusted and adjusted odds ratio (AOR) as a measure of effects was used. RESULTS: Of 1979 respondents, all were aware that sex determination is possible. Majority of them did not prefer sex determination (95.4%, 1888). About 80 (4.0%) preferred, while 11 (0.6%) were undecided about it. Majority of them were aware that sex determination without medical indication is a crime. Common source of information was healthcare workers (76.4%). After adjusting for confounders, age group (18-24, AOR = 5.334; 25-29, AOR = 3.249; 30-34, AOR = 3.857; 35-39, AOR = 2.279), middle level education (AOR = 2.3), those with unmet need for family planning (AOR = 2.970) and urban area (AOR = 67.679) subjects were preferred more; housewife (AOR = 0.481) and those without living son (AOR = 0.406) had preferred lesser for sex determination compared to their counterparts. CONCLUSION: About one in 25 currently married women preferred sex determination. It is comparatively more in urban areas. High-risk groups should be educated to develop correct awareness and attitude on prenatal sex determination.

Interaction of nutritional status and diabetes on active and latent tuberculosis: a cross-sectional analysis.

BACKGROUND: Malnutrition and diabetes are risk factors for active tuberculosis (TB), possible risk factors for latent TB infection (LTBI), and may interact to alter their effect on these outcomes. Studies to date have not investigated this interaction. METHODS: We enrolled 919 newly diagnosed active TB patients and 1113 household contacts at Primary Health Centres in Puducherry and Tamil Nadu, India from 2014 to 2018. In cross-sectional analyses, we used generalized estimating equations to measure additive and multiplicative interaction of body mass index (BMI) and diabetes on two outcomes, active TB and LTBI. RESULTS: Among overweight or obese adults, active TB prevalence was 12-times higher in diabetic compared to non-diabetic participants, 2.5-times higher among normal weight adults, and no different among underweight adults (P for interaction < 0.0001). Diabetes was associated with 50 additional active TB cases per 100 overweight or obese participants, 56 per 100 normal weight participants, and 17 per 100 underweight participants (P for interaction < 0.0001). Across BMI categories, screening 2.3-3.8 active TB patients yielded one hyperglycemic patient. LTBI prevalence did not differ by diabetes and BMI*diabetes interaction was not significant. CONCLUSIONS: BMI and diabetes are associated with newly diagnosed active TB, but not LTBI. Diabetes conferred the greatest risk of active TB in overweight and obese adults whereas the burden of active TB associated with diabetes was similar for normal and overweight or obese adults. Hyperglycemia was common among all active TB patients. These findings highlight the importance of bi-directional diabetes-active TB screening in India.

Prevalence and correlates of elder abuse: A cross-sectional, community-based study from rural Puducherry.

Background: Elder abuse is a neglected problem and needs to be addressed to improve the quality of life (QoL) of the elderly. We aimed to study the correlates of elder abuse in rural Puducherry. Methods: We conducted a cross-sectional, communitybased study among all the elderly people (60 years and above), from one of the four villages of a rural primary health centre in Puducherry. Participants were contacted at their homes. After obtaining consent, data were collected using (i) a structured, pre-tested questionnaire on sociodemographic details; (ii) elder abuse using the Hwalek-Sengstock Elder Abuse Screening Test; and (iii) QoL using WHO QoL-BREF. Multivariable logistic regression was used to identify predictors of elder abuse. Results: Of the 243 elderly individuals studied, 63% were women. The prevalence of elder abuse was 50.2%. On multivariable analysis, elderly with higher education status were found to have lower odds for suffering from abuse (primary education odds ratio [OR] 0.39 [0.18-0.84]; middle school OR 0.35 [0.14-0.86]; high school OR 0.08 [0.01-0.4]) compared to those with no formal education and those above 80 years of age were found to have higher odds for abuse (OR 3.02 [1.1-7.9]) compared to those <80 years, after adjusting for confounders such as sex, socioeconomic status, marital status and living arrangement. Conclusion: Half the elderly in our sample suffered from abuse. The higher age group and absence of formal education emerged as independent predictors of elder abuse.

Predictors of delayed care seeking for tuberculosis in southern India: an observational study.

BACKGROUND: Reducing delay to accessing care is necessary to reduce the Tuberculosis (TB) burden in high incidence countries such as India. This study aimed to identify factors associated with delays in seeking care for TB in Southern India. METHODS: We analyzed data from newly diagnosed, smear-positive, culture-confirmed, pulmonary TB patients in the Regional Prospective Observational Research for TB (RePORT) cohort in Puducherry and Tamil Nadu, India. Data were collected on demographic characteristics, symptom duration, and TB knowledge, among other factors. Delay was defined as cough ≥4 weeks before treatment initiation. Risky alcohol use was defined by the AUDIT-C score which incorporates information about regular alcohol use and binge drinking. TB knowledge was assessed by knowing transmission mode or potential curability. RESULTS: Of 501 TB patients, 369 (73.7%) subjects delayed seeking care. In multivariable analysis, risky alcohol use was significantly associated with delay (aOR 2.20, 95% CI: 1.31, 3.68). Delay was less likely in lower versus higher income groups (<3000 versus >10,000 rupees/month, aOR 0.31, 95% CI: 0.12, 0.78). TB knowledge was not significantly associated with delay. CONCLUSIONS: Local TB programs should consider that risky alcohol users may delay seeking care for TB. Further studies will be needed to determine why patients with higher income delay in seeking care.
