India's healthcare system is, for a large part, organized around a vast network of Primary Healthcare Centres (PHCs) that form the pillar on which the public healthcare sector functions. The World Health Organization (WHO) has emphasized the important role that PHCs play in strengthening community health and the provision of healthcare. Although a few studies have assessed specific elements of services offered by PHCs, only a few have studied the patients' perspectives on the functioning and performance of PHCs in the Indian context.

Background: Primary healthcare centres (PHCs) form the foundation of the Indian public health system, and thus their effective functioning is paramount in ensuring the population's health. The World Health Organisation (WHO) has set six aspects of performance assessment for general health systems, which are hardly applicable to the PHC setup in a low- and middle-income country. The Primary Health Care Performance Initiative (PHCPI) has prescribed a framework with five domains consisting of 36 indicators for primary healthcare performance assessment from a policy point of view.

Background: It is universally accepted that primary healthcare is essential for achieving public health and that assessment of its performance is critical for continuous improvement. The World Health Organization's (WHO's) framework for performance assessment is a comprehensive global standard, but difficult to apply in developing countries because of financial and data constraints. This study aims to review the empirical literature on measures for Primary Health Centre (PHC) performance assessment in developing countries, and compare them for comprehensiveness with the aspects described by the WHO Framework.

We tested the effectiveness of a program consisting of motivational interviewing (MI) and feedback of urine cotinine to stop passive smoking (PS) in children at risk for asthma. Fifty-eight families with children 0-13 years with a high risk of asthma and PS exposure were randomised in a one-year follow-up study. The intervention group received the intervention program during 6 sessions (1/month) and the control group received measurements (questionnaires, urine cotinine, and lung function) only.

Background: Stimulating successful tobacco cessation among employees has multiple benefits. Employees who quit tobacco are healthier, more productive, less absent from work, and longer employable than employees who continue to use tobacco. Despite the evidence for these benefits of tobacco cessation, a successful method to stimulate employees to quit tobacco is lacking.

Background: Asthma and obesity are highly prevalent in children, and are interrelated resulting in a difficult-to-treat asthma-obesity phenotype. The exact underlying mechanisms of this phenotype remain unclear, but decreased physical activity (PA) could be an important lifestyle factor. We hypothesize that both asthma and overweight/obesity decrease PA levels and interact on PA levels in asthmatic children with overweight/obesity.

Evidence from developing countries demonstrates a mixed relationship of overweight/obesity with socioeconomic status (SES) and place of residence. Theory of nutrition transition suggests that over the course of development, overweight first emerges among rich and urban people before spreading among rural and poor people. India is currently experiencing a rapid rise in the proportion of overweight and obese population especially among adult women.
