Article Synopsis
  • The study systematically reviewed how secondary smoking affects early childhood caries (ECC) in preschool children, focusing on children under 71 months old.
  • Out of 1243 publications, only 16 met the criteria for inclusion, leading to a meta-analysis showing that children exposed to secondary smoking have a significantly higher risk of developing caries.
  • The findings suggest a clear correlation between secondary smoking and ECC, but emphasize that further high-quality research is needed to strengthen these conclusions.

Primary health care (PHC) is the most effective way to improve people's health and well-being, and primary care services should act as the cornerstone of a resilient health system and the foundation of universal health coverage. To promote high quality development of PHC, an International Symposium on Quality Primary Health Care Development was held on December 4-5, 2023 in Beijing, China, and the participants have proposed and advocated the Beijing Initiative on Quality Primary Health Care Development. The Beijing Initiative calls on all countries to carry out and strengthen 11 actions: fulfill political commitment and accountability; achieve "health in all policies" through multisectoral coordination; establish sustainable financing; empower communities and individuals; provide community-based integrated care; promote the connection and integration of health services and social services through good governance; enhance training, allocation and motivation of health workforce, and medical education; expand application of traditional and alternative medicine for disease prevention and illness healing; empower PHC with digital technology; ensure access to medicinal products and appropriate technologies; and last, strengthen global partnership and international health cooperation.

Probationers, offenders with less serious and non-violent offences, and under statutory supervision, have low levels of self-esteem and physical health, and high level of family conflict, and poorer quality of family relationships. This study examined the effectiveness of the existing probation service and the additional use of a positive family holistic health intervention to enhance physical, psychological, and family well-being in probationers and relationships with probation officers. Probationers under the care of the Hong Kong Social Welfare Department were randomized into a care-as-usual control group (CAU), a brief intervention group (BI) receiving two 1-h individual sessions [of a brief theory-based positive family holistic health intervention integrating Zero-time Exercise (simple and easy-to-do lifestyle-integrated physical activity) and positive psychology themes of "Praise and Gratitude" in the existing probation service], or a combined intervention group (CI) receiving BI and a 1-day group activity with family members.
