The family is a crucial contributor to mental health and physical well-being. While bidirectional relationships between physical activity, diet, sleep, and mental well-being are well-documented, the influence of the family on these behaviours is less explored. This study aimed to examine the relationships between family resilience and individual lifestyle behaviours in community-dwelling adults, focusing on the roles of a supportive family health climate and reduced biobehavioural reactivity. Data were collected from 200 family dyads in Singapore through questionnaires assessing family resilience, health climate related to physical activity and nutrition, individual lifestyle behaviours (physical activity, diet, sleep), and demographics. Structural equation modelling was used to explore the connections between family resilience and individual lifestyle behaviours, particularly how family health climate and biobehavioural reactivity mediate these relationships. Participants included 200 dyads with a mean age of 42 years (SD = 15.18; range 15-85), 62.7% female and 67.3% with tertiary education. 85.5% were Chinese households and 83% lived in public housing. Family resilience was associated with increased engagement in physical activity, diet quality, and sleep quality, with higher engagement linked to lower biobehavioural reactivity and a healthier family health climate. Significant mediation effects were observed, with family resilience positively influencing physical activity (total indirect effect: β = .164, p < .001) and diet quality (β = .113, p = .004) through family health climate, while negatively impacting sleep quality (β = -.168, p < .001) mediated by biobehavioural reactivity. This study highlights that family dynamics significantly influence individual physical activity, dietary habits, and sleep quality, thereby enhancing health outcomes. Specifically, family resilience promotes healthier lifestyle behaviours by fostering a supportive family health climate and reducing biobehavioural reactivity. Interventions aimed at strengthening family resilience may thus provide a cost-effective strategy for improving population health.
家庭是心理健康和身体健康的重要贡献因素。虽然体育活动、饮食、睡眠与心理健康之间的双向关系已有充分记录，但家庭对这些行为的影响却较少被探讨。本研究旨在调查社区居住成年人的家庭复原力与个体生活方式行为之间的关系，重点关注支持性家庭健康氛围和降低生物行为反应性的作用。通过问卷调查收集了新加坡200个家庭二元组的数据，问卷评估了家庭复原力、与体育活动和营养相关的健康氛围、个体生活方式行为（体育活动、饮食、睡眠）以及人口统计学信息。采用结构方程模型来探索家庭复原力与个体生活方式行为之间的联系，特别是家庭健康氛围和生物行为反应性如何介导这些关系。参与者包括200个二元组，平均年龄为42岁（标准差=15.18；范围15 - 85岁），62.7%为女性，67.3%拥有高等教育学历。85.5%为华裔家庭，83%居住在公共住房中。家庭复原力与体育活动参与度增加、饮食质量和睡眠质量提高相关，更高的参与度与更低的生物行为反应性以及更健康的家庭健康氛围相关。观察到显著的中介效应，家庭复原力通过家庭健康氛围对体育活动产生积极影响（总间接效应：β = 0.164，p < 0.001）和饮食质量（β = 0.113，p = 0.004），而通过生物行为反应性对睡眠质量产生负面影响（β = -0.168，p < 0.001）。本研究强调家庭动态显著影响个体的体育活动、饮食习惯和睡眠质量，从而改善健康结果。具体而言，家庭复原力通过营造支持性的家庭健康氛围和降低生物行为反应性来促进更健康的生活方式行为。因此，旨在增强家庭复原力的干预措施可能为改善人群健康提供一种具有成本效益的策略。
