		 24 April 2019 | GENEVA: Children  under five must spend less time sitting watching screens, or restrained  in prams and seats, get better quality sleep and have more time for  active play if they are to grow up healthy, according to new guidelines  issued by the World Health Organization (WHO).
24 April 2019 | GENEVA: Children  under five must spend less time sitting watching screens, or restrained  in prams and seats, get better quality sleep and have more time for  active play if they are to grow up healthy, according to new guidelines  issued by the World Health Organization (WHO). 
“Achieving  health for all means doing what is best for health right from the  beginning of people’s lives,” says WHO Director-General Dr Tedros  Adhanom Ghebreyesus. “Early childhood is a period of rapid development  and a time when family lifestyle patterns can be adapted to boost health  gains.”
 
 The new guidelines on physical activity, sedentary behaviour and sleep  for children under 5 years of age were developed by a WHO panel of  experts. They assessed the effects on young children of inadequate  sleep, and time spent sitting watching screens or restrained in chairs  and prams. They also reviewed evidence around the benefits of increased  activity levels.
 “Improving physical activity, reducing sedentary time and ensuring  quality sleep in young children will improve their physical, mental  health and wellbeing, and help prevent childhood obesity and associated  diseases later in life,” says Dr Fiona Bull, programme manager for  surveillance and population-based prevention of noncommunicable  diseases, at WHO.
 
 Failure to meet current physical activity recommendations is  responsible for more than 5 million deaths globally each year across all  age groups. Currently, over 23% of adults and 80% of adolescents are  not sufficiently physically active. If healthy physical activity,  sedentary behaviour and sleep habits are established early in life, this  helps shape habits through childhood, adolescence and into adulthood.
 
 “What we really need to do is bring back play for children,” says Dr  Juana Willumsen, WHO focal point for childhood obesity and physical  activity. “This is about making the shift from sedentary time to  playtime, while protecting sleep. “
 The pattern of overall 24-hour activity is key: replacing prolonged  restrained or sedentary screen time with more active play, while making  sure young children get enough good-quality sleep. Quality sedentary  time spent in interactive non-screen-based activities with a caregiver,  such as reading, storytelling, singing and puzzles, is very important  for child development.
 The important interactions between physical activity, sedentary  behaviour and adequate sleep time, and their impact on physical and  mental health and wellbeing, were recognized by the Commission on Ending Childhood Obesity, which called for clear guidance on physical activity, sedentary behaviour and sleep in young children.
 
 Applying the recommendations in these guidelines during the first five  years of life will contribute to children’s motor and cognitive  development and lifelong health.
 
 Recommendations at a glance:
 
 Infants (less than 1 year) should: 
 
-  Be physically active several times a day in a variety of ways, particularly through interactivY
-  floor-based  play; more is better. For those not yet mobile, this includes at least  30 minutes in prone position (tummy time) spread throughout the day  while awake.
-  Not  be restrained for more than 1 hour at a time (e.g. prams/strollers,  high chairs, or strapped on a caregiver’s back). Screen time is not  recommended. When sedentary, engaging in reading and storytelling with a  caregiver is encouraged.
-  Have 14–17h (0–3 months of age) or 12–16h (4–11 months of age) of good quality sleep, including naps.
 
 Children 1-2 years of age should:
-  Spend  at least 180 minutes in a variety of types of physical activities at  any intensity, including moderate-to-vigorous-intensity physical  activity, spread throughout the day; more is better.
 
-  Not  be restrained for more than 1 hour at a time (e.g., prams/strollers,  high chairs, or strapped on a caregiver’s back) or sit for extended  periods of time. For 1-year-olds, sedentary screen time (such as  watching TV or videos, playing computer games) is not recommended. For  those aged 2 years, sedentary screen time should be no more than 1 hour;  less is better. When sedentary, engaging in reading and storytelling  with a caregiver is encouraged.
-  Have 11-14 hours of good quality sleep, including naps, with regular sleep and wake-up times.
 
 Children 3-4 years of age should:
-  Spend  at least 180 minutes in a variety of types of physical activities at  any intensity, of which at least 60 minutes is moderate- to vigorous  intensity physical activity, spread throughout the day; more is better.
-  Not  be restrained for more than 1 hour at a time (e.g., prams/strollers) or  sit for extended periods of time. Sedentary screen time should be no  more than 1 hour; less is better. When sedentary, engaging in reading  and storytelling with a caregiver is encouraged.
-  Have 10–13h of good quality sleep, which may include a nap, with regular sleep and wake-up times.
