Association between sedentary recreational time and cardiac autonomic modulation in adolescent boys: cross-sectional study

Individuals with Duchenne Muscular Dystrophy (DMD) have an impairment of cardiac autonomic function categorized by parasympathetic reduction and sympathetic predominance. The objective of this study was to assess the cardiac autonomic modulation of individuals with DMD undergoing therapy with Prednisone/Prednisolone and Deflazacort and compare with individuals with DMD without the use of these medications and a typically developed control group. Methods: A cross-sectional study was completed, wherein 40 boys were evaluated. The four treatment groups were: Deflazacort; Prednisone/Prednisolone; no corticoid use; and typical development. Heart Rate Variability (HRV) was investigated via linear indices (Time Domain and Frequency Domain) and non-linear indices Results: The results of this study revealed that individuals with DMD undertaking pharmacotherapies with Prednisolone demonstrated HRV comparable to the Control Typically Developed (CTD) group. In contrast, individuals with DMD undergoing pharmacotherapies with Deflazacort achieved lower HRV, akin to individuals with DMD without any medications, as demonstrated in the metrics: RMSSD; LF (n.u.), HF (n.u.), LF/HF; SD1, α1, and α1/α2, and a significant effect for SD1/SD2; %DET and Ratio; Shannon Entropy, 0 V%, 2 LV% and 2 ULV%. Conclusions: Corticosteroids have the potential to affect the cardiac autonomic modulation in adolescents with DMD. The use of Prednisone/Prednisolone appears to promote improved responses in terms of sympathovagal activity as opposed to Deflazacort.

Stress Levels

Abstract Background: Adolescence is a tumultuous period of hormonal and psychological transitions ranging from 10 to 19 years (WHO). This growth phase is usually accompanied by stressors. Very few studies have reported the prevalence of stress levels among adolescent boys. Our aim was to assess the prevalence and determinants of stress and its tolerance levels among high school boys. Methods: A cross sectional study design was selected for this purpose. A standardized self reported questionnaire was administered to 1153 high school boys. A score of 130 and more was used to classify the participants as stressed. Results: The prevalence of stress and its tolerance levels was found to be 55% and 33.7%, respectively. Also correlations suggest that parental education and occupational status play a significant role in adolescent stress. Together, these findings suggest necessitating an intervention to counter the same. Conclusion: The proportion of stressed adolescent boys (55.5%) reported to have poor stress tolerance (41%). Studies addressing stress among high school adolescents remain unexplored. The basic determinants of stress are not researched upon these age groups. Our study reports the prevalence of stress to be 55% among high school boys. This could be the fundamental basis of designing suitable stress management programs for adolescents that could reduce their stress levels.

Background: Tobacco abuse is one of the biggest curses that modern society has come across. It is not confined to any one country or region alone, but has widely afflicted the globe. The most susceptible time for initiating use of tobacco in India is adolescence and early adulthood, ages 15-24 years while some start as young as 10 years.Approximately 55,500 adolescent start using tobacco every day in India, joining the 7.7 million young people under the age of 15 who already use tobacco on a regular basis.Methods: It is a community based cross-sectional study conducted among school going adolescent boys of urban field practice area of medical college during July to September 2017. Data was collected through pretested semi-structured self -administered questionnaire given to students by the investigators. Data collected were analyzed using statistical package for social sciences (SPSS) 17 software.Results: The prevalence of ever use of tobacco was 17.5% among school going adolescent boys in urban field practice area. In the present study it was observed that 174 (95.1%) adolescent boys had knowledge regarding hazards of tobacco. 110 adolescents (60.1%) had knowledge that passive smoking was harmful.Conclusions: The study suggests that the prevalence of tobacco consumption was high among school going adolescent boys in urban field practice area of medical college. The knowledge of students regarding harmful effects of tobacco was not adequate. Attitude and practice regarding tobacco consumption is also not satisfactory.

Abstract This study aimed to analyze the relationship of physical activity in different domains with cardiac autonomic modulation in adults. A sample of 252 adults was randomly selected, with mean age of 42.1 (± 16.5) years, being 58% of women. Cardiac autonomic modulation was assessed through indexes of heart rate variability in time (SDNN, RMSSD) and frequency (LF, HF) domains for linear method, and by Poincaré plot for non-linear method (SD1, SD2 components). Domains of PA (occupation, sport, leisure time/commuting, and total) were assessed by Baecke’s questionnaire. Variables of age, gender, socioeconomic status (questionnaire) and body mass index (objectively measures) were covariates. Occupational PA was positively related to LF (β = 2.39, 95% CI 0.24; 4.54), sports PA was positively related to SDNN (β = 3.26, 95% CI 0.18; 7.05), RMSSD (β = 4.07, 95% CI 0.31; 7.85), and SD1 (β = 2.85, 95% CI 0.11; 5.81), and leisure time/commuting PA was positively related to SDNN (β = 3.36, 95% CI 0.28; 6.70) and RMSSD (β = 3.53, 95% CI 0.46; 7.52) indexes. Total PA was related to RMSSD (β = 1.70, 95% CI 0.04; 3.72). Sports, leisure time/commuting, and total PA were related to higher parasympathetic modulation, while occupational PA was related to higher sympathetic modulation to the heart in adults.
