RESUMO

Background: COVID-19 was declared as a Public Health Emergency of International Concern on 30th January 2020. Compared to the general population, healthcare workers and their families have been identified to be at a higher risk of getting infected with COVID-19. Therefore, it is crucial to understand the risk factors responsible for the transmission of SARS-CoV-2 infection among health workers in different hospital settings and to describe the range of clinical presentations of SARS-CoV-2 infection among them. Methodology: A nested case-control study was conducted among healthcare workers who were involved in the care of COVID-19 cases for assessing the risk factors associated with it. To get a holistic perspective, the study was conducted in 19 different hospitals from across 7 states (Kerala, Tamil Nadu, Andhra Pradesh, Karnataka, Maharashtra, Gujarat, and Rajasthan) of India covering the major government and private hospitals that were actively involved in COVID-19 patient care. The study participants who were not vaccinated were enrolled using the incidence density sampling technique from December 2020 to December 2021. Results: A total of 973 health workers consisting of 345 cases and 628 controls were recruited for the study. The mean age of the participants was observed to be 31.17 ± 8.5 years, with 56.3% of them being females. On multivariate analysis, the factors that were found to be significantly associated with SARS-CoV-2 were age of more than 31 years (adjusted odds ratio [aOR] 1.407 [95% CI 1.53-1.880]; p = 0.021), male gender (aOR 1.342 [95% CI 1.019-1.768]; p = 0.036), practical mode of IPC training on personal protective equipment (aOR 1. 1.935 [95% CI 1.148-3.260]; p = 0.013), direct exposure to COVID-19 patient (aOR 1.413 [95% CI 1.006-1.985]; p = 0.046), presence of diabetes mellitus (aOR 2.895 [95% CI 1.079-7.770]; p = 0.035) and those received prophylactic treatment for COVID-19 in the last 14 days (aOR 1.866 [95% CI 0.201-2.901]; p = 0.006). Conclusion: The study was able to highlight the need for having a separate hospital infection control department that implements IPC programs regularly. The study also emphasizes the need for developing policies that address the occupational hazards faced by health workers.

RESUMO

OBJECTIVES: India introduced BBV152/Covaxin and AZD1222/Covishield vaccines in January 2021. We estimated the effectiveness of these vaccines against severe COVID-19 among individuals aged ≥45 years. METHODS: We did a multi-centric, hospital-based, case-control study between May and July 2021. Cases were severe COVID-19 patients, and controls were COVID-19 negative individuals from 11 hospitals. Vaccine effectiveness (VE) was estimated for complete (2 doses ≥ 14 days) and partial (1 dose ≥ 21 days) vaccination; interval between two vaccine doses and vaccination against the Delta variant. We used the random effects logistic regression model to calculate the adjusted odds ratios (aOR) with a 95% confidence interval (CI) after adjusting for relevant known confounders. RESULTS: We enrolled 1143 cases and 2541 control patients. The VE of complete vaccination was 85% (95% CI: 79-89%) with AZD1222/Covishield and 71% (95% CI: 57-81%) with BBV152/Covaxin. The VE was highest for 6-8 weeks between two doses of AZD1222/Covishield (94%, 95% CI: 86-97%) and BBV152/Covaxin (93%, 95% CI: 34-99%). The VE estimates were similar against the Delta strain and sub-lineages. CONCLUSION: BBV152/Covaxin and AZD1222/Covishield were effective against severe COVID-19 among the Indian population during the period of dominance of the highly transmissible Delta variant in the second wave of the pandemic. An escalation of two-dose coverage with COVID-19 vaccines is critical to reduce severe COVID-19 and further mitigate the pandemic in the country.

RESUMO

BACKGROUND: Approaching 100 million in number, India has the second largest population of elderly people after China. India's elderly are growing faster than the general population. By the year 2050, the number of elderly population is expected to increase to 323 million. In the geriatric population, fall is the leading cause of nonfatal injuries and hospital admissions. Falls account for 40% of all injury deaths, and the death rates are the highest among 60 years and above in all the regions of the world. OBJECTIVES: The objective of this study is to assess the factors associated with the risk of fall among the elderly of 60 years and older in rural Kattankulathur block. MATERIALS AND METHODS: The study is a community-based case-control design among the elders in a rural setting. Those who had fallen in the past 12 months were selected as cases, and an equal number of age- and gender-matched controls were selected. Multiple logistic regression was conducted with biological, behavioral, environmental, and socioeconomic variables. RESULTS: Of the 747 elderly contacted for the survey, 140 cases and 140 controls each were selected based on self-reported fall in the previous 12 months. The mean age of the participants was 66 with 95% confidence interval (65-67). Individual risk factors for fall were fear of falling (odds ratio [OR] 6.7) and dizziness (OR 4.9). CONCLUSIONS: There is now, more than ever, a need to refocus public health priorities for falls prevention in rapidly aging elders in India. This study provides a much-needed information for further investigation into fall and fall-related injury in developing countries like India.

RESUMO

BACKGROUND: Depression among elderly is an important public health problem responsible for considerable morbidity and disability. Causes of depression are multifactorial and often preventable. As there was dearth of community studies in Tamil Nadu, the present study was undertaken. OBJECTIVES: The objective of this study is to estimate the prevalence of depression and to assess the factors which are associated with depression among elderly. METHODS: A cross-sectional study was done from July 2014 to July 2015 among elderly in Kattankulathur block with a sample size of 690 by cluster sampling method. House-to-house interview was conducted using a predesigned, pre-tested questionnaire, and depression was assessed using geriatric depression scale-30. Data were analyzed using SPSS version 20 (Trial). The statistical tests used were proportions, Chi-square test. P<0.05 was considered to be statistically significant. RESULTS: The overall prevalence of depression was 35.5% (95% confidence interval: 31.9%-39.0%). Sociodemographic factors such as female sex, nuclear family, being widowed, unemployed status, low socioeconomic status, financially dependent, medical factors such as cardiac disease, visual impairment, arthritis, anemia, life events such as conflicts in family, death of the family member or close relative, and illness of self/family member were significantly associated with depression (P < 0.05). CONCLUSIONS: More strength of association for depression was seen with low socioeconomic status, nuclear family, low-intensity work, conflicts in the family, death of family members using multiple logistic regression. These findings show the need for proper care by the family members and counseling for the elderly which are of much importance in preventing depression.

RESUMO

BACKGROUND: Almost all institutions, colleges, universities and homes today were using computer regularly. Very little research has been carried out on Indian users especially among college students the effects of computer use on the eye and vision related problems. AIM: The aim of this study was to assess the prevalence of computer vision syndrome (CVS) among medical and engineering students and the factors associated with the same. SUBJECTS AND METHODS: A cross-sectional study was conducted among medical and engineering college students of a University situated in the suburban area of Chennai. Students who used computer in the month preceding the date of study were included in the study. The participants were surveyed using pre-tested structured questionnaire. RESULTS: Among engineering students, the prevalence of CVS was found to be 81.9% (176/215) while among medical students; it was found to be 78.6% (158/201). A significantly higher proportion of engineering students 40.9% (88/215) used computers for 4-6 h/day as compared to medical students 10% (20/201) (P < 0.001). The reported symptoms of CVS were higher among engineering students compared with medical students. Students who used computer for 4-6 h were at significantly higher risk of developing redness (OR = 1.2, 95% CI = 1.0-3.1,P = 0.04), burning sensation (OR = 2.1,95% CI = 1.3-3.1, P < 0.01) and dry eyes (OR = 1.8, 95% CI = 1.1-2.9, P = 0.02) compared to those who used computer for less than 4 h. Significant correlation was found between increased hours of computer use and the symptoms redness, burning sensation, blurred vision and dry eyes. CONCLUSION: The present study revealed that more than three-fourth of the students complained of any one of the symptoms of CVS while working on the computer.

RESUMO

A study was conducted to estimate prevalence of metabolic syndrome among 150 rural women in the age group of 30-50 years in a primary health centre area in Tamil Nadu. Prevalence of metabolic syndrome was estimated using National Cholesterol Education program (NCEP), Third report Adult Treatment Panel ATP III criteria, and Modified NCEP ATP III criteria for Asian Indians. Prevalence of metabolic syndrome was found to be 30.7% based on NCEP, ATP-III Criteria. Based on the Modified NCEP, ATP-III Criteria, the prevalence was found to be 36%.The most commonly observed components of metabolic syndrome in this study was increased waist circumference (56.0%) followed by low HDL (45.3%), high triglyceride (37.3%), high blood pressure 29.3%, and fasting blood sugar 12.7%. Identifying the risk factors and treating patients with the metabolic syndrome is a public health challenge especially in the rural population.

RESUMO

A population based cross-sectional study was carried out to assess the awareness, attitude, and treatment seeking behaviour regarding TB in rural Tamil Nadu. Out of 1985 people interviewed, 56% had heard of TB, but 80% were not aware of the cause and mode of spread of TB. Television was reported to be the main source of information (45%). Only 34% people were aware that treatment for TB was available free of cost. Less than 10% people felt the need to maintain confidentiality, if contracted TB. More than 80% people preferred to visit Government hospital, if developed TB, whereas 54% actually sought treatment from government hospital for cough of more than three weeks.
