Parental perspectives on physical inactivity and unhealthy diet as linked Non-Communicable Disease (NCD) risk factors among adolescents in Coastal Karnataka, India: a qualitative study.
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundUnhealthy dietary practices and physical inactivity during adolescence are key contributors to the future burden of non-communicable diseases (NCDs). Although parental influence on adolescents' lifestyle behaviours is well recognized, evidence from low- and middle-income countries (LMICs), particularly within context-specific settings, remains limited. This study aimed to explore parents' perspectives on physical inactivity and unhealthy dietary practices as inter-related risk factors for NCDs among adolescents in Coastal Karnataka, India.
methodsThis qualitative study employed semi-structured interviews with 16 parents (10 mothers and 6 fathers) of adolescents aged 11-17 years in Coastal Karnataka, India. Participants were purposively recruited to ensure variation across school types and socio-economic backgrounds. Interviews were audio-recorded, transcribed verbatim, and analysed using a hybrid inductive-deductive thematic approach informed by the Capability-Opportunity-Motivation Behaviour (COM-B) model, Social Cognitive Theory, and the Theory of Planned Behaviour.
resultsSix interrelated themes were identified: (1) sustained awareness of healthy behaviours with a persistent awareness-practice gap; (2) the home environment as a space of negotiation rather than control; (3) normalization of intermittent unhealthy dietary practices and episodic physical inactivity; (4) academic demands as key barriers to healthy lifestyles; (5) schools as conditional but time-limited protective environments; and (6) gendered and culturally embedded influences on physical activity. Despite high levels of awareness, parents reported increasing difficulty in sustaining healthy behaviours due to academic pressures, adolescents' autonomy, and environmental constraints.
conclusionsParental recognition of the importance of healthy behaviours is constrained by structural, academic, and socio-cultural factors that limit sustained adoption. Interventions targeting adolescent NCD prevention in LMIC settings should adopt multi-level strategies that integrate family support, school-based initiatives, and context-specific considerations such as academic pressures and cultural practices.
