ABSTRACT

BACKGROUND: Unhealthy eating and lack of exercise during adolescence culminated into earlier onset and increasing burden of atherosclerotic cardiovascular diseases (CVDs) worldwide. Among urban Indian adolescents, prevalence of these risk factors of CVD seemed to be high, but data regarding their pattern and predictors was limited. To address this dearth of information, a survey was conducted among urban adolescent school-students in Kolkata, a highly populated metro city in eastern India. METHODS: During January-June, 2014, 1755 students of 9th-grade were recruited through cluster (schools) random sampling. Informed consents from parents and assents from adolescents were collected. Information on socio-demographics, CVD-related knowledge and perception along with eating and exercise patterns were collected with an internally validated structured questionnaire. Descriptive and regression analyses were performed in SAS-9.3.2. RESULTS: Among 1652 participants (response rate = 94.1%), about 44% had poor overall knowledge about CVD, 24% perceived themselves as overweight and 60% considered their general health as good. Only 18% perceived their future CVD-risk and 29% were engaged in regular moderate-to-vigorous exercise. While 55% skipped meals regularly, 90% frequently consumed street-foods and 54% demonstrated overall poor eating habits. Males were more likely to engage in moderate-to-vigorous exercise [adjusted odds ratio (AOR) = 3.40(95% confidence interval = 2.55-4.54)] while students of higher SES were less likely [AOR = 0.59(0.37-0.94)]. Males and those having good CVD-related knowledge were more likely to exercise at least 1 h/day [AOR = 7.77(4.61-13.07) and 2.90(1.46-5.78) respectively]. Those who perceived their future CVD-risk, skipped meals more [2.04(1.28-3.25)] while Males skipped them less [AOR = 0.62(0.42-0.93)]. Subjects from middle class ate street-foods less frequently [AOR = 0.45(0.24-0.85)]. Relatively older students and those belonging to higher SES were less likely to demonstrate good eating habits [AOR = 0.70(0.56-0.89) and 0.23(0.11-0.47) respectively]. A large knowledge-practice gap was evident as students with good CVD-related knowledge were less likely to have good eating habits [AOR = 0.55(0.32-0.94)]. CONCLUSIONS: CVD-related knowledge as well as eating and exercise habits were quite poor among adolescent school-students of Kolkata. Additionally, there was a large knowledge-practice gap. Multi-component educational interventions targeting behavioral betterment seemed necessary for these adolescents to improve their CVD-related knowledge, along with appropriate translation of knowledge into exercise and eating practices to minimize future risk of CVDs.

ABSTRACT

BACKGROUND: Increasing burden of cardiovascular risk-factors among adolescent school-children is a major concern in India. Dearth of information regarding the burden of these factors and the efficacy of educational intervention in minimizing them among urban school-students of India called for a school-based, educational intervention involving a representative sample of these students and their caregivers. METHODOLOGY: Using a randomized-controlled design with stratified-random sampling, 1000 students (approximately 50/school) of 9th grade from 20 randomly selected schools (representing all socio-economic classes and school-types) and their caregivers (preferably mothers) will be recruited. Objectives of the study will include: estimation of the baseline burden and post-interventional change in cardiovascular risk-factors, related knowledge, perception and practice among participants in Kolkata. DATA COLLECTION: After obtaining appropriate consent (assent for adolescents), collection of the questionnaire-based data (regarding cardiovascular disease/risk-factor related knowledge, perception, practice), anthropometric measurements, stress assessment and cardiological check-up (pulse and blood pressure measurement along with auscultation for any abnormal heart sounds) will be conducted for each participating students twice at an interval of six months. In between 6 educational sessions will be administered in 10 of the 20 schools randomized to the intervention arm. After the follow-up data collection, same sessions will be conducted in the non-interventional schools. DATA ANALYSES AND DELIVERABLE: Descriptive and inferential analyses (using SAS 9.3) will be conducted to determine the distribution of the risk-factors and efficacy of the intervention in minimizing them so that policy-making can be guided appropriately to keep the adolescents healthy in their future life.

ABSTRACT

AIMS: Little information exists about the use of noninvasive methods to characterized left ventricular mechanical adaptation during normal pregnancy. The aim of this study was to evaluate left ventricular performance during normal pregnancy and study the effect of maternal factors. METHODS AND RESULTS: The study was conducted at Govt. Medical College and New Civil Hospital, Surat between February 2006 to March 2008. M-mode and Doppler echocardiography was performed in 31 normal pregnant women at 30-40 weeks and 8-12 weeks postpartum. Heart rate, stroke volume, cardiac output and left ventricular mass increased significantly, while total vascular resistance decreased significantly during last trimester of pregnancy. Left ventricular contractility indices (percentage ejection fraction and fraction shortening) were within normal limit during pregnancy but fractional shortening was significantly higher post-partum than in the last trimester of pregnancy (p < 0.05). Maternal age was related to the transmitral peak velocity of early filling (E, p = 0.001) and the E to A ratio (p < 0.001), while height was related to heart rate (p < 0.001), stroke volume (p = 0.003), cardiac output (p < 0.001) and left ventricular mass (<0.005). CONCLUSION: This study express that along with gestation, maternal anthropometric profile may affect cardiac performance. Systolic performance was better in tall individuals and diastolic performance was better in younger individuals.
