Prevalence of clustering of non-communicable disease risk factors in a highly urbanized district of India: findings of a cross-sectional survey in Puducherry.

Background: In an individual, the development and severity of Non-Communicable Diseases (NCDs) are determined by the presence or absence of clustering of NCD risk factors in them. We aimed to determine the prevalence and the factors associated with clustering of risk factors of NCDs in the district of Puducherry in India. Methodology: We conducted a community-based cross-sectional survey among the adult population (18-69 years) of Puducherry district (N = 1114) between February 2019 and February 2020. Ten risk factors of NCDs (behavioral, physical measurements and biochemical) were assessed. Individuals having ≥ 3 risk factors were regarded as having clustering of risk factors. Categorical variables are summarized using proportions (95% CI). Adjusted prevalence ratio was estimated using weighted forward stepwise generalized linear modelling. Results: Clustering of NCD risk factors was present in majority (95.2%, 95% CI: 93.8-96.3) of the population. The presence of clustering was significantly higher among women (97.1%, 95% CI: 95.9-98.3) and the urban population (97.2%, 95% CI: 96.1-98.3). The risk factors that primarily drove the high prevalence of clustering were raised salt intake and inadequate intake for fruits and vegetables in nine out of 10 people in the district. Nearly 1 in 10 (13.3%, 95% CI: 11.3-15.3), 1 in 5 (21.5%, 95% CI: 19.1-23.8) and 1 in 4 (26.8%, 95% CI: 24.1-29.4) participants had three, four and five risk factors, respectively. Conclusion: We highlight the urgent need for population-based health promotion interventions in the district of Puducherry targeting the highly prevalent NCD risk factors, especially among the women and urban populations.

Predictors of Control Status of Hypertension in India: A Systematic Review and Meta-analysis.

Predictors of hypertension (HTN) control status have not been well understood in India. This information is crucial for policymakers and program managers to devise newer HTN control strategies and implement relevant policies and programs. Therefore, we undertook this meta-analysis to estimate the effect of various factors on the control status of HTN in India. We systematically searched PubMed and Embase for observational studies and community-based trials published between April 2013 and March 2021 conducted among people (≥ 15 years) with hypertension in India. Quality of studies was assessed using Newcastle Ottawa (NO) scale. Meta-analysis was performed using random effects model. We reported the effect of various factors on the prevalence of controlled HTN using pooled odds ratio (OR) with 95% confidence interval (CI). Of the 842 studies screened, we analyzed nine studies that included 2,441 individuals. Based on the NO scale, majority (90%) of studies had a low risk of bias. The odds of having controlled HTN were significantly higher among women (OR 1.78, 95% CI 1.62-1.95), those aged > 45 years (OR 1.69, 95% CI 1.44-1.97), and those residing in urban parts of India (OR 1.74; 95% CI 1.48-2.03). These measures varied considerably across different regions of the country. Very few studies reported data on the relationship between behavioural risk factors of non-communicable diseases (NCDs) and HTN control status. We did not find any statistically significant differences between behavioural risk factors of NCDs and HTN control status. To improve HTN control in India, the ongoing/newer HTN control programs need to target men, those aged 15-45, and rural residents. Future studies on HTN control determinants should report disaggregated data and use standardized definitions for behavioral risk factors to enhance reliability and comprehensiveness of findings on the determinants of HTN control in future reviews.

Cost-effectiveness of population-based screening for microalbuminuria in people with type 2 diabetes mellitus in India.

OBJECTIVES: Patients with diabetes have a higher risk of developing chronic kidney disease (CKD). Early detection of CKD through microalbuminuria screening, followed by treatment, delays the progression of CKD. We evaluated the cost-effectiveness of population-based screening of microalbuminuria among normotensive type 2 diabetes mellitus patients aged >40 years compared with no screening scenario using a decision tree combined with the Markov model. METHODS: We considered two scenarios: Scenario I - dipstick microalbuminuria followed by spot-urine albumin-creatinine ratio (ACR) and serum creatinine in sequence; Scenario II - spot urine ACR plus serum creatinine. A mathematical cohort of the target population was simulated over a lifetime horizon with an annual cycle. Data for the model were obtained from secondary resources. The incremental cost-effectiveness ratios (ICERs) were estimated for screening scenarios compared to nonscreening scenario, along with sensitivity analyses. RESULTS: The discounted ICER per quality-adjusted life years gained for annual microalbuminuria screening in the normotensive diabetic population in India were ₹ 24,114 (US$ 308) and ₹ 13,790 (US$ 176) for scenarios I and II, respectively. Annual screening by scenarios I and II resulted in a reduction of 180 and 193 end-stage renal disease (ESRD) cases per 100,000 population, respectively, resulting in a cost saving of ₹ 12.3 and 13.3 Crore spent on ESRD management over 10 years. Both scenarios were also cost-effective even at the screening frequencies of 5 and 10 yearly. CONCLUSION: Microalbuminuria screening was cost-effective at the threshold of one-time GDP per capita in India.

Control status of hypertension in India: systematic review and meta-analysis.

BACKGROUND AND AIMS: Uncontrolled hypertension is a major risk factor for cardiovascular diseases (CVDs). The present study aimed to conduct a systematic review and meta-analysis to estimate the pooled prevalence of control status of hypertension in India. METHODS AND RESULTS: We carried out systematic search (PROSPERO No.: CRD42021239800) in PubMed and Embase published between April 2013 and March 2021 followed by meta-analysis with random-effects model. The pooled prevalence of controlled hypertension was estimated across geographic regions. The quality, publication bias and heterogeneity of the included studies were also assessed. We included 19 studies with 44 994 hypertensive population, among which 17 studies had low risk of bias. We found statistically significant heterogeneity ( P  ≤ 0.05) and absence of publication bias among the included studies. The pooled prevalence of control status among patients with hypertension was 15% (95% CI: 12-19%) and among those under treatment was 46% (95% CI: 40-52%). The control status among patients with hypertension was significantly higher in Southern India 23% (95% CI: 16-31%) followed by Western 13% (95% CI: 4-16%), Northern 12% (95% CI: 8-16%), and Eastern India 5% (95% CI: 4-5%). Except for Southern India, the control status was lower among the rural areas compared with urban areas. CONCLUSION: We report high prevalence of uncontrolled hypertension in India irrespective of treatment status, geographic regions and urban and rural settings. There is urgent need to improve control status of hypertension in the country.

Perception of Threat and Efficacy in Contracting COVID-19 Infection among Tobacco Users - A Cross-sectional Analytical Study from Four Indian States.

BACKGROUND: To trigger quit intention and practice of preventive measures for COVID-19 among tobacco users; it is imperative for them to be well aware of the fact that they are at higher risk of COVID-19 infection and should be at higher efficacy to practice preventive measures for the disease as compared to nonusers of tobacco. OBJECTIVES: This community-based cross-sectional analytical study was conducted from April 2020 to May 2020 among 1203 adult participants to compare the threat and efficacy perception among users and nonusers of tobacco. MATERIALS AND METHODS: Perception of threat was assessed using three questions on perceived threat and one question on perceived susceptibility; whereas perception of efficacy was assessed using four questions each on self-efficacy and response efficacy through telephonic interview. RESULTS: There was no significant difference in the overall threat perception among users and nonusers of tobacco. However, state-wise analysis showed that tobacco users had higher perception of threat for SARS-CoV-2 infection in all the states except Telangana. The overall perception of efficacy among tobacco users was significantly higher as compared to nonusers of tobacco. CONCLUSION: The study calls for active collaboration between tobacco control enthusiasts and the Government to promote awareness of a higher risk of COVID-19 disease among tobacco users. In essence, the study's implications extend beyond COVID-19 and can guide targeted efforts to promote awareness, behavior change, and collaboration in the context of other infectious diseases among tobacco users.

Impact of second wave of COVID-19 pandemic on the hesitancy and refusal of COVID-19 vaccination in Puducherry, India: a longitudinal study.

The second wave of COVID-19 pandemic has spread rampantly throughout India between April and May 2021, leading to high mortality rates. Identifying any change in the rate of vaccine hesitancy or refusal due to such mass casualty events will provide further insights on developing appropriate risk communication strategy. Hence, this study was undertaken to identify the vaccine hesitancy and refusal before and during the second wave of COVID-19 pandemic. We conducted a longitudinal study among 900 adults to know about their vaccine hesitancy and refusal pattern before (March 2021 - round-1) and during the second wave of COVID-19 pandemic (May 2021 - round-2). Telephonic interview was conducted using the pre-tested semi-structured questionnaire. There was an increase in the vaccine hesitancy (27.8% in round-1 to 32.7% in round-2) and refusal (25.6% in round-1 to 35.6% in round-2) during the second wave of pandemic in Puducherry. In adjusted analysis, vaccine hesitancy was found to increase by 1.19 times during the round-2 survey compared to round-1 survey (aIRR = 1.19; 95%CI: 1.03-1.37). We also found that the vaccine refusal increased by 1.40 times during the round-2 survey compared to round-1 survey (aIRR = 1.40; 95%CI: 1.22-1.62) after adjusting for age, place of residence, and occupation. We found that the confidence in COVID-19 vaccine efficacy and safety has declined over time leading to increase in the vaccine hesitancy and refusal in our study cohort, with more than one-third refusing to get themselves vaccinated during the second wave of pandemic.
