ABSTRACT
In India, 14.6% of adolescents are currently using tobacco in any form and tobacco control is a major public health challenge. The objective of this systematic review is to analyze all the existing literature and evaluate the effectiveness of school-based tobacco use prevention programs for adolescents in India. The review protocol was registered in PROSPERO (CRD42020159535). Studies were selected using database search, manual search, gray literature, reference chasing, and contacting the authors. All randomized controlled trials, cluster-randomized trials, quasi-experimental, and non-randomized studies reporting school-based tobacco use preventive interventions for adolescents in India; articles published in English (other languages where it can be translated to English) published between January 2000 till May 2020 were included. Data was independently extracted by two reviewers. The Risk of bias (RoB) and quality of the study were assessed using appropriate tools. Among 7972 identified articles, only 13 studies met the inclusion criteria. Each study implemented a unique intervention and measured distinct outcomes. Postintervention, all the studies reported improvements in the study group with respect to the reduction of tobacco use and change in the knowledge, attitude, practices, and/or behavior outcome parameters. Twelve study results were based on short-term assessment. Overall, a 5.17–17.0% tobacco use reduction rate was noted. RoB was high for six studies. Key methodological problems related to study design, duration, outcome parameter, follow-up time, type of intervention, and attrition were identified. School-based tobacco use prevention programs for adolescents in India might have shown positive outcomes but are associated with significant limitations.
ABSTRACT
Purpose: To investigate the practical value of using questionnaires (self perceived assessment) as compared with clinical examinations (normative assessment) and to evaluate the role of socioeconomic status and implications of the results in understanding the public perception of oral health. Materials and Methods: This was a cross-sectional single-blind study. A purposive sample of 860 bank employees of Belgaum city, India, were asked to fill in a close-ended questionnaire inquiring about their socioeconomic status, dental, periodontal health levels and treatment needs. Clinical examinations, employing the WHO dentition status and Community Periodontal Index, were performed to determine normative status and needs. Perceived and normative assessments were compared for sensitivity, specificity, positive and negative predictive values. Results: The kappa values ranged from 0 (treatment needs) to 0.67 (for prosthesis). The degree of agreement with the following kappa values and sensitivity was seen in filled teeth (0.52, 60%), missing teeth (0.62, 83.8%), and prosthesis (0.67, 58.3%). However, the disagreement was seen with all other questions with average kappa value of 0.20. Conclusions: Self-assessment questionnaires were of low value in evaluating dental, periodontal health status and treatment needs in the study subjects. Findings reflect a low level of awareness that may influence care-seeking behavior and socioeconomic status has a clear role to play in dental health perception.
