Background:The Chinese government has taken many incentives to promote the implementation of the family doctor (FD) contract service; however, whether primary health care providers establishing a strong relationship with patients that shapes their loyalty is still unknown. Under this circumstance, drawing the public attention to patient loyalty in primary care and clarifying the underlying mechanism of loyalty is imperative to the development of primary care.Objective: To analyse the effect of patient perceived involvement on patient loyalty in primary care, investigate the mediating role of patient satisfaction, and explore the moderating role of the FD contract service on the relationship between patient perceived involvement and patient loyalty.Methods: A cross-sectional questionnaire survey of patients in primary health facilities was conducted in Jilin province of China. Participants comprised 1334 patients selected via a multi-stage sampling method.Results: Patient perceived involvement not only had a direct positive impact on patient loyalty but also had an indirect effect on patient loyalty via patient satisfaction. Furthermore, for patients who contracted with FDs, patient perceived involvement had a higher direct effect and indirect effect on patient loyalty when compared with patients who did not contract with FDs.

Participation by patients with chronic diseases under primary health care requires more attention to achieve effective disease management and better health outcomes. In 2016, China proposed accelerating the establishment of a system of family doctors (FDs) and strengthening doctor-patient communication to better meet residents’ health service needs. This study aimed to describe perceived participation in primary health care among patients with chronic diseases in northeastern China and explore the impact of FD contract services and patient’s trust on patients’ perceived participation. A cross-sectional survey of 847 patients with chronic diseases in 16 primary healthcare institutions was conducted in Jilin Province, China. Among all participants, 453 patients reported signing up for FD contract services (62.93%). The perceived participation of patients with chronic diseases was at a low level (mean = 6.71 and SD = 3.35). After controlling for sociodemographic variables and health-related variables, FD contract services directly and indirectly influenced patients’ perceived participation. The patient’s trust was a mediator in the relationship between FD contract services and perceived participation. This study confirmed the valuation of family doctor contract services and provided a theoretical basis for the formulation of primary health service policies. Health organizations should continue to enhance the capacity of primary health services and attract more chronic disease patients to contract with FD teams, thereby enhancing doctor-patient trust and increasing patient’s participation in primary health care.

Background: Intention to smoke is an important predictor of future smoking among adolescents. The purpose of our study was to examine the interaction between academic performance and parents/peer tobacco use on adolescents’ intention to smoke. Methods: A multi-stage stratified sampling was used to select participants, involving 9394 students aged between 9–16 years in Changchun city, northeastern China. Multiple logistic regression analyses were conducted to examine the individual effect of academic performance and peer/parental smoking behavior. Stratified logistic regressions were conducted to examine the protective effect of academic performance based on peer or parental smoking. Interaction effects of academic performance × peer/parental smoking on adolescents’ intention to smoke were tested. Results: Of all the non-smoking students sampled, 11.9% intended to smoke within the next five years. The individual effect of academic performance and peer/parental smoking was significant. The protective effect of academic performance on the intention to smoke was significant regardless of whether peers smoked or not. However, the protective effect was not significant among adolescents with only maternal smoking and both parental smoking. The current study found the significant interaction effects of academic performance × peer smoking and the academic performance × both parents’ smoking. Students with poor academic performance were more likely to intend to smoke if their peers or both parents smoked. Conclusion: These preliminary results suggest that peer smoking or smoking by both parents reinforces the association between low academic performance and the intention to smoke among adolescents. Enhancing school engagement, focusing on social interaction among adolescents with low academic performance, and building smoke-free families may reduce adolescents’ intention to smoke.
