Clinical Trial Summary

This proposed 'KeySteps Phase Two Study' is a 5-year study, which aims to investigate the effectiveness and sustainability of a Community Child Health Model with different services related to healthy lifestyle programmes and health promotion implemented in community settings of deprived living areas. Potential participants are children studying or living in the five selected districts, namely Sham Shui Po, Yuen Long, Tuen Mun, Sha Tin and Kowloon City. Data including children's health and psychosocial conditions, and family demographics will be collected. In addition, subjects will receive on-site assessments on general health and development. Medical and health related events of subjects will be tracked through the existing health care system. Subjects will receive health promotion services and/or lifestyle modification programmes according to their needs.

Description:

With the improved economy and rapid growth of socio-economic activities, the socioeconomic gaps between social groups in Hong Kong are widening continuously. According to the Hong Kong Poverty Report of Oxfam Hong Kong (OHK), the richest decile of households made 34.3 times more than the poorest decile prior the COVID pandemic (2019), that number surged to 47.3 times by the first quarter of 2022.1 Similar to the experience in other countries, children from low socio-economic status (SES) families in Hong Kong are at higher risk of physical health, psychological and behavioural problems including obesity/overweight and hypertension, visual, behavioural and learning problems.

Major chronic diseases such as central obesity, hypertension, diabetes mellitus, ischemic heart disease, degenerative retinal and other eye diseases are found to be rooted in childhood related to unhealthy lifestyles, adverse thriving and nutritional environment. The COVID-19 pandemic has exaggerated the existing risks and led to emerging threats among young children, especially in disadvantaged families in Hong Kong in the past two years. With the stringent social isolation, school suspension and home confinement, children's physical health, developmental and behavioral problems have worsened. Experience in a local project, KeySteps@JC funded by HKJC 2017-2022 showed that children in deprived districts were susceptible to nutritional imbalance, physical inactivity and weight problems, especially during the COVID-19 period. Another study also reported the overuse of electronic devices in disadvantaged families. Several other studies also indicated that there were adverse health effects related to COVID-19 pandemic including obesity, deteriorated physical fitness, visual impairment in particular myopia, sleep and emotional disturbance, decreased school readiness, and increased risk of child maltreatment, inattention/hyperactivity and neurodevelopmental disorders, etc.

Lifestyle modification addresses the poor lifestyle choices that are the root causes of chronic diseases. The goal of the lifestyle modification programme is to empower the patient with knowledge, skills, and a desire to create and maintain new habits which are needed to manage their chronic disease and potentially eliminate the root cause. Parental or family involvement in interventions is found to be impactful on lifestyle changes in children, leading to favourable health outcomes. As a result of modelling their parents' behaviour, children are more likely to adopt a healthy lifestyle if their parents demonstrate healthy lifestyle behaviours. Research also found that parents perceived social support to be a key enabler for children to eat healthfully and be active. Group-based health interventions may encourage the building of peer support with additional benefits of social support in the community.

Although lifestyle modification programmes seem promising to address the increasing need of young children, they have not been widely implemented in early childhood public health settings as a main health promotion and disease prevention strategy. This research is to investigate the effectiveness and sustainability of a Community Child Health Model with different services related to healthy lifestyle programmes and health promotion implemented in community settings of deprived living areas.

Potential participants are children studying or living in the five selected districts, namely Sham Shui Po, Yuen Long, Tuen Mun, Sha Tin and Kowloon City. Those districts shared some common disadvantaged backgrounds such as families with lower socio-economic status, mostly living in subdivided units and crowded housing, insufficient public play area and early childhood services. According to the Hong Kong Poverty Situation Report from Census and Statistics Department in 2018, Yuen Long ranked 2nd highest, Tuen Mun 4th, Sham Shui Po 5th, Sha Tin 6th and Kowloon City 9th in terms of 0-6 years old child living in poverty population.11 Moreover, Sham Shui Po was the second-highest district with subdivided units12and Kowloon City ranked third in terms of the number of partitioned flats and second-lowest districts in the public play space area managed by Leisure and Cultural Services Department (LCSD).

This study will be conducted in compliance with the protocol, Declaration of Helsinki and other applicable regulatory requirements.
