Health-related physical fitness, physical activity and its correlates among school going adolescents in hilly state in north India: a cross sectional survey.

INTRODUCTION: Health-related physical fitness, which includes body composition, cardiorespiratory fitness, muscular endurance, flexibility, power, and strength are associated with risks of chronic diseases and promote good health and wellness. There have been reports of increasing levels of physical inactivity among children and adolescents, leading to increasing rates of obesity and decreased physical fitness. The present study was conducted among school going adolescents to estimate the levels and correlates of PF for timely intervention. METHODOLOGY: School based cross-sectional study was done among students of class 8-11th in Government schools of Garhwal division of Uttarakhand. Multistage stratified random sampling was applied for recruitment of study participants. We recruited a final sample size of 634 students. Validated questionnaires and standard methods for assessment of physical fitness, physical activity levels and other variables such as waist circumference, hip circumference, BMI and hemoglobin estimation were done. RESULTS: Average and above average cardiorespiratory fitness score as per Harvard step test among boys (54.3%) was significantly higher as compared to girls (21.3%) (χ2 = 88.93, p < 0.001). There was a significant association between gender and dominant handgrip strength (χ2 = 8.02, p = 0.01) as well as between gender and Shoulder stretch test (SST) of dominant (χ2 = 17.5, p < 0.05) as well as nondominant arm (χ2 = 13.5, p < 0.05). Sit and reach test results also showed a significant association with gender (χ2 = 27.17, p < 0.001). Gender, hemoglobin level, BMI and PAL scores significantly predicted cardiorespiratory fitness scores (R2 = 0.188, F value of the model = 37.69, p =< 0.001)). CONCLUSION: Physical fitness of school going adolescents in Garhwal division of Uttarakhand was better than other parts of India, with significant gender differences. Physical activity levels (PAL) were poor and are also a significant predictor of physical fitness. More emphasis needs to be paid on the health and fitness of girl students. School based policies to increase PAL among students through innovation and rewards may go a long way in improving the long-term health of the students.

The Effect of Two Health Education Packages on Nutritional Knowledge, Practices, and Physical Activity Levels Among School-Going Adolescents in Rishikesh: A Cluster Randomized Trial.

Introduction Adolescence is a critical period known for presenting specific challenges in disease treatment and health promotion. Studies have highlighted that increased nutritional awareness is associated with healthier eating habits, while regular physical activity aids in controlling and preventing non-communicable diseases. Equipping adolescents with health education in schools prepares them to adopt and maintain healthy lifestyles throughout their lives. To assess and compare the efficacy of health education packages targeting nutrition knowledge, practices, and physical activity levels, a cluster-randomized trial was conducted among school-going adolescents. Methodology Two distinct health education packages were developed for the two intervention groups. In group 1, a health talk supported by a flip chart was delivered, followed by pamphlet distribution. In contrast, in group 2, only information pamphlets were distributed. The study was conducted in government schools in Rishikesh, with four schools selected. Two schools were randomly allocated to each intervention arm. In each school, a questionnaire was administered to assess the students' nutrition knowledge, practices and physical activity levels. This was followed by the intervention, and the students were reassessed for the same parameters after two weeks. Result The pre-intervention and post-intervention comparisons within the same group- the mean scores for nutrition knowledge, food practice, sleep duration, and recreational screen time were comparable in the intervention group 1 (p>0.05). There was a decrease in the mean physical activity score and screen time for studies in intervention group 1, and these differences were statistically significant (p<0.05). The mean scores for nutrition knowledge, physical activity, sleep duration, and screen time for studies were comparable in the intervention group 2 (p>0.05). There was an increase in the mean food practice score and a decrease in recreational screen time in intervention group 2, and these differences were statistically significant (p<0.05). On comparing the groups with each other, it was found that Group 2 exhibited a significantly higher mean food practice score compared to group 1 post-intervention. While there was a statistically significant decrease in the mean physical activity score in intervention group 1, this group still had higher physical activity levels than group 2. Post-intervention, group 2 exhibited a higher screen time for studies compared to group 1. Both groups had comparable sleep durations at baseline and post-intervention, with intervention group 1's mean sleep duration falling within the recommended range set by the American Academy of Sleep Medicine. Regression analysis provided valuable insights into the relationship between baseline values of various variables and their post-intervention values, aiding in understanding the impact of the health education packages. Conclusion The findings emphasize the significance of incorporating nutrition and physical activity education into the curriculum of students.
