General practitioners (GPs) are in prime position to help shape their patients' lifestyle habits from a very young age. Learn the latest integrated activity guidelines for children and adolescents, and how GPs can get involved through patient assessment, physical activity promotion and referral to a specialist centre when needed.  


Childhood is a critical period for adopting healthy lifestyle behaviours and shaping the foundation for present and future well-being.

The World Health Organization also advocates for early interventions in childhood to offer the best protection against noncommunicable diseases (NCDs) such as cardiovascular diseases, cancers, chronic respiratory diseases and diabetes.1

To promote healthy lifestyle habits in Singapore children, the College of Paediatrics and Child Health, Singapore has published the Singapore Integrated 24-Hour Activity Guidelines for Early Childhood (aged under seven years), and for Children and Adolescents (aged seven to 17 years) to provide up-to-date recommendations and resources.2-3


The proportion of Singapore students who were overweight (i.e., body mass index-for-age at or above the 90th percentile) increased from 13% to 16%, from 2017 to 2021.4

Furthermore, only 44.4% of children and adolescents met the Global Recommendations on Physical Activity for Health – a daily average of 60 minutes or more of moderate to vigorous physical activity (MVPA).5


There is strong evidence that regular physical activity among the paediatric population improves:6-7

  • Physical fitness

  • Muscle strength

  • Cardiometabolic health (e.g., blood pressure, fasting glucose and cholesterol)

  • Bone health

There is also some evidence that physical activity reduces the risk of adiposity and depression, and improves motor skill development and cognitive function among this group.6-7


While the Singapore Integrated 24-Hour Activity Guidelines comprise physical activity, sedentary behaviour, sleep, and dietary and eating habits framed within a 24-hour concept, we will focus on the physical activity recommendations in this article.2-3




(0 to <1 year)

  • Be physically active several times daily within a safe and supervised environment

  • Activities include non-screen based, interactive floor-based play and tummy time

  • Build up tummy time towards 30 minutes or more, spread throughout the day


(1 to <3 years)

  • Accumulate 180 minutes or more of physical activity throughout the day within a safe environment

  • Daily outdoor play is highly encouraged


(3 to <7 years)

  • Accumulate 180 minutes or more of physical activity throughout the day within a safe environment

  • Daily outdoor play is highly encouraged

  • Physical activity for older pre-schoolers (5 to 6 years) should include 60 minutes or more of MVPA daily, and muscle- and bone-strengthening activities several times a week

Children and adolescents 

(7 to 17  years)

  • Accumulate a daily average of 60 minutes or more of MVPA

  • Engage in muscle- and bone-strengthening exercises 3 times or more in a week

  • Engage in light physical activities throughout the day



GPs can provide advice on physical activity during routine check-ups of paediatric patients, and identify those who will benefit from physical activity counselling or prescription.

Additionally, GPs are also able to help them adopt these new lifestyle habits through regular reviews, and provide timely referral for those who require further assessments or treatment.


1. Assessment of physical activity

  • GPs can assess the amount of physical activity using the Get Active Questionnaire:8

  • During a typical week, on how many days do you do moderate- to vigorous-intensity aerobic physical activity (e.g., brisk walking, cycling or jogging)? (Days/week)

  • On days that you do at least moderate-intensity aerobic physical activity (e.g., brisk walking), for how many minutes do you do this activity? (Minutes/day)

2. Physical activity recommendations

GPs can provide advice on the recommended amount and type of activities for the respective age groups based on the Singapore Integrated 24-Hour Activity Guidelines.2-3

The guidelines include a practical reference section with examples of activities, practical tips and community resources available to help both GPs and parents/caregivers.

3. Referral to a specialist centre

GPs can refer patients to the Singapore Sport and Exercise Medicine Centre @ KK Women's and Children's Hospital (SSMC@KKH) for further evaluation or treatment.

The patients include but are not limited to the following:

  • Patients who 'failed' pre-participation screening using the Get Active Questionnaire

  • Patients requiring an exercise prescription or programme for treatment

  • Patients experiencing symptoms during exercise

SSMC@KKH is able to provide patient-centric exercise counselling and prescription, and conduct inpatient exercise programmes for children up to 18 years of age. SSMC@KKH also performs pre-participation screening and cardiopulmonary exercise tests for paediatric patients and athletes.


GPs play a pivotal role in shaping the patient's lifestyle habits from a very young age, and by adopting healthy lifestyle habits during childhood, we aim to provide them with the best start in life.

We hope that through the benefits of regular physical activity, the patient will continue to practise these healthy habits in his or her adulthood and reduce the risks of NCDs.
