Classroom intervention to improve behavioral intention toward regular physical activity among adolescents.

Background: During adolescence, a critical phase in human life, the groundwork for a healthful future is established. Physical inactivity poses a significant risk factor for non-communicable diseases (NCDs) and related mortality worldwide. To assess adolescents' behavioral intentions regarding regular physical activity, the Theory of Planned Behavior (TPB) examines 'Attitude,' 'Subjective norm,' and 'Perceived behavioral control.' Utilizing TPB, this study focuses on evaluating the impact of a school-based health promotion intervention on behavioral intentions toward physical activity among urban adolescents in West Bengal, India. Methods: A school-based nonrandomized controlled interventional study with parallel group design was conducted among adolescents aged between 12 and 16 years. Behavioral intention towards performing regular physical activity was determined with the measurements of the constructs from the TPB. Cluster analysis was conducted using measurements from both the intervention and control groups. Participants with higher mean scores in the constructs were classified as intenders, while the rest were considered non-intenders. The intervention's impact was evaluated by calculating the Relative Risk (RR) through a generalized linear model with robust standard error estimates, to ascertain the probability of belonging to the higher intention cluster. Result: Following the intervention, construct-wise scores improved significantly, particularly the perceived behavioral control mean score in the intervention group. The Relative Risk (RR) of becoming an intender for regular physical activity in the intervention group was 1.24 (95% CI: 1.04-1.48) when compared to the control group. Conclusion: Health Promoting Schools has been recognized as a strategic and cost-effective vehicle to promote positive development and healthful living, and the current evidence suggests they can effectively reduce the emergence of significant NCD risk factor like physical inactivity. Schools must establish strong partnerships with diverse stakeholders to address barriers beyond the school environment and enhance their control over critical issues.

Perception and Acceptance of the Newly Introduced COVID-19 Precaution (THIRD) Vaccination Dose among Health Workers at an Indian Medical College.

INTRODUCTION: India has run a nationwide vaccination campaign against COVID-19, which has recently introduced a precaution (third) dose for health workers. This study assessed the perception and attitude of health workers toward the Indian vaccination campaign against COVID-19, with an emphasis on this major change. MATERIALS AND METHODS: A printed questionnaire was distributed among health-care workers at the Medical College of West Bengal. The completed forms were analyzed. RESULTS: Most of the participants were doctors (83.7%). Although all had received two doses of vaccine before, 44.4% were unwilling to be vaccinated with the third dose in the present scenario. The majority (63.8%) of the patients were concerned about side effects. The emergence of new COVID strains (65.6%) was viewed as a threat to the effectiveness of the vaccines. Participants with higher age, comorbidities, and those with the perception that the third dose was being introduced appropriately and would be effective against newer strains of the vaccine tended to be more willing to get vaccinated with the precaution dose compared to their counterparts. CONCLUSION: A dilemma regarding the acceptance of precaution doses was noted among health workers. This warrants the availability of more comprehensive information to increase acceptance of these vaccines.

Addiction habits in a rural cohort of injection drug users and effects on serum lipid profile: Analysis of a repeated measures study from an eastern state of India.

Background Injecting drug use (IDU) is associated with several cardiometabolic risks. We aimed to measure the independent effects of IDU behaviour and related factors on serum lipid profile among people who inject drugs (PWIDs). Methods We did a longitudinal study with six follow-up measurements at an interval of 2 months among 104 PWIDs from 11 selected hotspots under two blocks in West Bengal, India. Generalized estimating equations with robust standard errors analysed the effect of addiction habits on lipid profile parameters. Results The mean (SD) age of the participants was 27.6 (5.24) years, 36.5% married and 44.3% were unemployed at the time of recruitment. At the baseline, the mean (SD) body mass index (BMI) and fasting blood sugar (FBS) were 20.0 (1.82) kg/m2 and 112.0 (15.90) mg/dl, respectively. The mean duration of drug use was 2.5 (1.20) years. While 62.5% had normal triglyceride (TG), 14.4% had high total cholesterol (TC) and 69.2% had dyslipidaemia at the baseline. Adjusted for age, BMI, FBS and other addiction-related variables, models showed that longer duration of drug use (>3 years) resulted in higher levels of TG, higher TC-to-high-density lipoprotein ratio and dyslipidaemia. Tobacco use and high FBS level were also risk factors for dyslipidaemia. Conclusions Higher duration of IDU, tobacco use and higher FBS were associated with deranged lipid profile among PWIDs.
