The clustering of risk behaviours in adolescence and health consequences in middle age.

INTRODUCTION: There is increasing interest in the clustering of risk behaviours in adolescence. However, few studies have examined what clusters of risk behaviours exist among adolescents, their early-life predictors, and their associations with later health. METHODS: We analysed data derived from 8754 participants (women 53.3%) in the 1970 British Cohort Study. Latent class analysis was used to identify clusters of risk behaviours at age 16. Regression modelling was then used to examine predictors of clusters and their consequences of risk behaviours and health outcomes at age 42. RESULTS: We identified two latent classes: a risky-behaviour (men: 20.0%, women: 23.6%) and less-risky-behaviour class. Among men, those in the risky-behaviour class were more likely to report smoking, multiple binge drinking, sexual debut before 16, involvement in fights and delinquency than were women. Membership in risky-behaviour class was mainly predicted by sociodemographic and parental risk behaviours and monitoring. The risky-behaviour class at age 16 was associated with the following outcome age 42: smoking status (more strongly among women), excessive alcohol consumption (more strongly among men), worse self-rated health (more strongly among men), and psychological distress (only among women). CONCLUSIONS: Engagement in multiple risk behaviours in adolescence is an important driver of health inequalities later in life. Early life intervention, for example via school-based interventions, may be warranted for favourable lifelong health.

Parenting attitudes and dimensions as predictors of adolescent behavioural problems in the Indian context: A community-based study.

INTRODUCTION: Adolescent behavioural problems are a growing public health concern. The authors in this study investigated paternal and maternal reports of parenting attitudes and dimensions as predictors of adolescent behavioural problems in the Indian context. MATERIALS AND METHODS: Using stratified sampling at the community level, 640 parents including 419 mothers and 221 fathers participated in the study. Tools included a socio-demographic pro-forma; Parental attitude inventory (PAI) to assess parenting attitudes, Parent Global Report of the Alabama Parenting Questionnaire (APQ) to assess current parenting dimensions, and the parent version of the Strengths and Difficulties Questionnaire (SDQ) to assess behavioural problems among adolescents. We examined the prevalence and predictors of total difficulties, externalizing and internalizing behavioural problems among adolescents from paternal and maternal reports. RESULTS: Paternal and maternal reports of total difficulties (11.3 %, 13.6 %), externalizing (2.3 %, 1.9 %) and internalizing behaviours (8.6 %, 7.4 %) among adolescents are reported. Predictors of abnormal behaviours per paternal reports included lower social class and poor paternal control. Being a male adolescent increased the odds of total difficulties and externalizing problems. Favourable maternal attitude, good maternal warmth and control predicted the reduced likelihood of total difficulties and externalizing behaviours per maternal reports. Paternal control and maternal warmth and control were found to reduce the likelihood of internalizing behaviours among adolescents. CONCLUSION: Maternal attitude, paternal control and maternal warmth and control dimensions emerged as significant predictors of total difficulties, externalizing and internalizing behavioural problems among adolescents.
