Patterns of health-related behaviours among adolescents: a cross-sectional study based on the National Survey of School Health Brazil 2012

Abstract

Objectives: The aim of this study was to analyse the clustering of multiple health-related behaviours among adolescents and describe which sociodemographic characteristics are associated with these patterns.Design: Cross-sectional study. Setting: Brazilian schools assessed by the National Survey of School Health (PeNSE, 2012).Participants: 104 109 Brazilian ninth-grade students from public and private schools (response rate=82.7%). Methods: Exploratory and confirmatory factoranalyses were performed to identify behaviour clustering and linear regression models were used to identify socio-demographic characteristics associated with each one of these behaviour patterns.Results: We identified a good fit model with three behaviour patterns. The first was labelled 'problembehaviour' and included aggressive behaviour, alcohol consumption, smoking, drug use and unsafe sex; the second was labelled 'health-compromising diet and sedentary behaviours' and included unhealthy food indicators and sedentary behaviour; and the third was labelled 'health-promoting diet and physical activity' and included healthy food indicators and physical activity. No differences in behaviour patterns were found between genders. The problembehaviour pattern was associated with male gender, older age, more developed region (socially and economically) and public schools (compared with private). The 'health-compromising diet and sedentary behaviours' pattern was associated with female gender, older age, mothers with higher education level and more developed region. The 'health-promoting diet and physical activity' pattern was associated with male gender and mothers with higher education level.Conclusions: Three health-related behaviour patterns were found among Brazilian adolescents. Interventions to decrease those negative patterns should take into account how these behaviours cluster together and the individuals most at risk.

Systematic review of childhood and adolescence sedentary behavior: analysis of the Report Card Brazil 2018

“…[11][12][13] Most of the studies used self-reported questionnaires, but less than half the studies reported information about instrument validity. 9,14,17,18,[30][31][32][33]36,42,[52][53][54][59][60][61][62]65,[67][68][69][70][73][74][75][77][78][79][80][81]86,93,94,97,[99][100][101][102][103][104][105][106] Only three studies assessed sedentary behavior using accelerometers. 11,15,16 The cut-off point used in the studies varied considerably from 2 to 4 hours, although most studies used cut-off point of 2 hours of screen time: 20 studies 18,20,21,27,[30][31][32][33]…”

The current status of syphilis prevention and control in Jiangsu province, China: A cross-sectional study

“…In particular, clinicians at these institutions should receive more extensive training in syphilis prevention knowledge and PISTC services. At the same time, we should improve patient education so that patients feel comfortable seeking help from healthcare providers after unsafe sex [ 21 ].…”

Sport Types and Time Spent Playing Sport Are Associated with Eating Pattern Among Young Brazilian Athletes

“…The athletes reported on their weekly frequency of physical exercise (1,2,3,4, and ≥ 5 days per week), annual competition frequency (1 per year, or ≥ 2 per year), sports type (volleyball, basketball, handball, or soccer), and time spent practicing this sport (months). We used a validated and reproducible questionnaire from The Brazilian National School-Based Health Survey (PeNSE) (16,20) to assess the eating pattern. Food consumption was assessed based on the frequency of consumption of the 5 following healthy food items in the previous 7 days: bean, raw salad (cucumber, lettuce, tomato, carrot, and onion), vegetables (cabbage, chayote, broccoli, spinach, and pumpkin), fruits, and milk; as well as the 5 following unhealthy food items in the previous 7 days: deep-fried salty snacks, processed meat (hamburger, sausage, and ham), bagged salty snacks, sweets, and soft drinks.…”
